The first 7 and second 8 razmerchik pen blades, and optoelectronic head 26 of the first 10 and second 11 measuring channels are placed respectively on the second 5 and third 6 carriages on opposite sides of the pen controlled vanes 13.

Each of the optoelectronic heads 26 consists of a source 34 of a light beam such as a laser, the photodetector 35 and lens 36 (figure 1). This controlled blade 13 is installed between the optical head 26 so that the lens 36 provide triangulation optical communication photodetectors 35 sources 34 a narrow light beam through the corresponding surface of the pen blades 13.

Thus the outputs 42 and 43 of the block 29 scanner is connected to the clock inputs 44 and 45, respectively optoelectronic head 26 and the block 28 of the code generation.

Photodetectors 35 optoelectronic heads 26 each made in the form of a photodiode line (not shown).

Structurally, each of the measuring channels 10 or 11 can be placed inside the corresponding optoelectronic head 26 (Fig 1).

Marker 7 or 8 pen blades (figure 3) comprises a cylindrical housing 46 made of a nonmagnetic material, inside which is placed a marker 47 and spring 48 preload, adjusting washer 49 and the fastening screw 50, and an Executive body, consisting of winding 51 is placed on the housing 46, and installed inside the housing 46 of the armature 52 with a spring 53 preload. Marker 47 has a fibrous rod 54, impregnated ink liquid, such as ink. On the ends of the cylindrical body 46 by means of threaded connections fixed cover 56 and the lug 57.

Bus 58 of the winding 51 is connected to the relevant control outputs 59 and 60 of the PC 12 (figure 2).

Snap 9 to install the blade contains the node 61 fixation of the scapula and the node 62 mates with the first carriage 4 (figure 1).

Node 61 of the fixing blade consists of the fixed and movable parts and the stationary part provides the necessary orientation of the blades 13 in the space, Breakfast is as, and the movable part is intended to ensure the sustainability of its location in this position.

Figs.4-7 stationary part of the node 61 fixation is a stand 63 to set shank blades 13 and contains the basic elements 64.

On figa, b (front and left) stand 63 contains three basic element 64 in the form of lugs, and the movable part of the node 61 fixation is made in the form of a spring-loaded lever 65. When attaching the blades 13, the lever 65 is released, the shank of the blade 13 is placed on the stand 63, pressed to the basic elements 64 and in this position is fixed by a spring-assisted lever 65.

On figa, b (front and left) stand 63 contains one basic element 64 in the form of a stop and the two base element 64, the surfaces of which repeat the mating surface of the shank blades 13 (in the form of a "Christmas tree"). The movable part of the node 61 fixation is made in the form of a clamped screw (slider) 66. When attaching the blades 13, the slider 66 is put aside, the shank of the blade 13 is placed in the grooves of two basic elements 64, pressed against the base of the stop 64 and in this position is fixed by the slider 66.

Figure 6 stand 63 contains one basic element 64 in the form of emphasis and one basic element 64 in the form of a plane on which is mounted the shank of the blade 13. The movable part of the node 61 fixation is made in the form of a spring-loaded on the zunka 67. When mounting the blade 13 by pressing the slider 67 is pressed (up-drawing), the shank of the blade 13 is placed on the base surface 64 of the cradle 63, pressed against the base of the stop 64 and in this position the fixed spring-loaded slider 67.

On figa, b, (front, top and back) stand 63 is made in the shape of a frame and consists of six basic elements 64 in the form of emphasis placed on the inner surface. The movable part of the node 61 fixation is made in the form of a spring-loaded lever 68 mounted on the specified frame. When attaching the blades 13, the lever 68 is released, the shank of the blade 13 is pressed shank and pen to six basic elements 64 and in this position is fixed by a spring-assisted lever 68.

The choice of the construction site 61 fixation depends on the shape and size controlled blade (workpiece) and the particular design of optoelectronic devices control the geometric parameters of the blades. In all cases, the feather blades 13 are rigidly oriented in a vertical plane, while the axis 69 also lies in the vertical plane (the X-Z plane), in particular, may be parallel to the X-axis (as in figure 1) or the Z-axis of the device coordinate system.

Node 61 fixation together with controlled blade 13 is attached to the node 62 mates with the first carriage 4 (figure 1).

The proposed optoelectronic monitoring device g is americasa parameters blades can operate in two modes: mode control (measurement) and the layout.

Before working device in a control mode in the PC 12 is entered, the program control (measurements) and the necessary source data, including tolerances in the geometry of the blades 13, and with the help of the fixing unit 9 is positioning (orientation) of the pen blades 13 in the vertical plane, for example according to figure 1.

Geometric control vanes assumes that the measured values of the distance a and b from the center of the optical systems 36 optoelectronic heads 26 to points of the contour sections of the pen blades 13 (smfg).

The operation of the device begins with the issuance with the PC 12 signal installation, in which all blocks are set to the initial state "0", and the carriage 4-6 occupy the original position. In the drawings, the installation scheme "0" conventionally not shown.

The control signal from the output 17 of the carriage 4 with the actuator 14 and the linear displacement sensor 20, moves the blade 13 in the horizontal plane (in the direction perpendicular to the plane of the drawing in figure 1) to a predetermined program of measurements of the coordinates of X.

Further, the device operation is based on the principle of optical triangulation. Light sources 34 both optoelectronic heads 26 are directed respectively at two opposite points on the path "section" pen blades 13.

Diffuse (diffuse) radiation over the spine of the pen focusing lens 36 to the corresponding photodetectors 35 in the form of light marks.

Block 29 scanner generates clock pulses, providing an optoelectronic converting image light marks on the photodiode lines of the photodetector 35.

Such a transformation takes place in such a way that changes the coordinates of these light marks on the photodetector 35 is proportional to the change of the profile of the blades 13. Image light marks cause changes in the levels of stress in individual cells photodiode arrays, resulting in the distribution of the output signals of the photodiode cells in a time when reading is proportional to the spatial intensity distribution of the light on the cross sections of light marks on the photo-diode arrays.

Information signals from outputs 38 optoelectronic heads 26 are received at the inputs of blocks 37 27 selection signal and further inputs 28 40 units code generation.

The blocks 28 of the code generation measuring channels 10 and 11 provide a measurement of time from the beginning of the survey photodiode ranges to mid-videokursov coming from block 27, which is equivalent to the distance from the beginning of the photodiode lines to the power centers of light marks. As a result, the blocks 28 measuring channels 10 and 11 are formed of digital equivalents of the measured values a and b (figure 1).

Measurement of the values a and b ends overwriting them in memory PAVM. At the same time in the memory of the PC 12 with sensors 20-22 linear movements of the carriages 4-6 entered the appropriate codes of the coordinate values X and Z.

In the next moment on the respective output 17 reappears signal, under which the carriage 4 moves the blade 13 to the new X-coordinates of the horizontal plane and the above-described measurement procedure is repeated.

Upon completion of the specified program number of such operations measurement procedure is terminated, and in the PC 12 is formed by a set of values a and b and the corresponding values of X and Z for a given blade 13.

According to the data in the PC 12 are calculated geometrical parameters of the scapula, in particular the thicknesses of the pen blades in given areas (figure 1):

h=-(a+b)

where C is the distance between the centers of the optical systems (the constant is defined constructively).

In the future, the results of calculations in the PC 12 are compared with predetermined values of geometrical parameters of the scapula (tolerances). If the calculated parameters are outside the tolerances, they form a set of deviations of geometrical parameters of the blades 13 and can be printed and/or displayed on a PC monitor 12, as well as marked (indicated) on the surface of the pen blades for further mechanical processing (see the next mode of the device).

The device layout is as follows.

The control signal from the corresponding output 17 of the carriage 4 moves the blade 13 in a horizontal plane to a given program X, which is the deviation from the geometric tolerance parameter.

Upon completion of this operation on the control signals from the respective outputs 18 and 19 of the carriage 5 and 6 are moved in a vertical plane to a given program coordinate Z, in which razmerchik 7 and 8 are installed across local areas blades 13, which has its output parameters outside tolerances.

In the next moment on the respective outputs 59 and 60 of the PC 12 are formed short control signals in the winding 51 of Ruzmetov 7 and 8. In this case the electromagnetic field winding 51 acts on the corresponding anchor 52. As a result, the anchor 52, overcoming the resistance of the spring 53, sharply strikes the marker 47. Marker 47 for a short time takes off from the housing 46 and its fibrous rod 54, impregnated ink liquid hits the local area pen blades 13, leaving a mark.

Under the action of springs 53 and 48 of the anchor 52 and the handle 47 is returned to its original position.

In the next moment on the respective output 17 reappears signal, under which the caret is ka 4 moves the blade 13 to the new X-coordinates of the horizontal plane and above the partitioning is repeated.

The results of the markup can be used for mechanical tuning the geometrical parameters of the corresponding local areas of the blades 13 to the desired values.

It should be noted that the second 5 and third 6 carriage can move in the directions of Z independently of one another, which allows also independently from each other to measure placed on them optoelectronic heads 10 and 11 (at the same X coordinate).

Similarly, a possible implementation and layout.

Thus, a new set of essential features optoelectronic devices control the geometric parameters of the blades allows you to:

a) to improve the device performance by parallelizing operations geometry measurement vanes simultaneous measurements of both surface and thereby increase the performance of your device, and also the achievement of the possibility of determining the thickness of the pen blade on the local areas in a single pass through the measurement area, without changing orientation;

b) to increase the accuracy of the geometric parameters of the scapula by the orientation of the pen blade in the vertical plane (mounting on edge, when there is minimal deflection) and obtain measurement results for one base without seniorenheim in the measurement process;

C) to extend the functionality of the device by automatic labeling of local areas of the pen blade on which its geometric parameters are outside the tolerances (usually specified marking is done manually, which is characterized by high complexity and low precision);

g) due to the proposed construction site of fixation of the scapula to quickly install and remove the blade, which also improves the performance of the described device.

The most effective use of this device with a large range (sizes) of the controlled blades, which is often the case in practice.

The application of this device in one of the enterprises of Moscow to control the geometry of the compressor and turbine blades, which further proves its compliance with the conditions of patentability "industrial applicability".
