EFFECT: simple design and high stability of operation of the engraving device.

The technical field.

The invention relates to engraving devices designed for machining of surfaces of solid materials.

The prior art.

Known engraving device includes a base with a fixed rack, to which is attached one end of a flat spring, and the other with one end of the l-shaped yoke of an electromagnet attached to the plate rigidly mounted on the base. To the other end of the l-shaped yoke attached to the collet, which features a percussion instrument in the form of needles with a diamond tip, on the basis of the control-Cam installed the bearing is fixed by the screw, with the ability to track topography of the workpiece, the gap between the workpiece and the point of the needle should be less than 0.02 mm, with the possibility of transmission of color without distortion (RF patent for useful model №67926, IPC WV 3/00 (2006.01), 2007 [1]).

The disadvantage of this analog is the use of a flat spring. When repeated flexing mechanical flat spring stops to restore its shape, resulting in replacement for preserving the quality of the engraving.

Known engraving device And containing a stepper motor, the control winding with which the control unit receives control is engaged pulses. On the motor shaft mounted rocker with the working tool at the end. The rocker is equipped with a lever, to which is rigidly connected to the first disk permanent magnets, in parallel with the second permanent magnets. The second magnets placed on the adjusting elements, which are fixed to the body. In the case also fixed the motor (the stator of the motor). The first and second magnets are a differential circuit in the mode of repelling forces (RF patent for the invention №2429139, IPC WV 3/00 (2006/01), 2011 [2]).

The disadvantage of this analogue is the presence of a lever, which is fixed to the first magnet. This complicates the design, reduces the maintainability of the rocker arm and reliability of the entire device. When working engraving device rocker makes angular oscillation. The probability of damage is the breaking of the arm with magnets, which leads to having to replace the entire arm.

Another drawback of this analogue is the performance gap between the magnets open. This leads to it from dust from treated surfaces, which, for granite, for example, is itself magnetic. It is mechanically limits the amplitude of the drummer and changes the strength of the interaction of the magnets, which leads to the need podster the key.

The third disadvantage of this is similar fastening the second magnets of the adjusting elements. It also complicates the design and reduces the stability of the device. To configure the device requires a accurate calculations for the establishment of equilibrium. To satisfy the law of conservation of energy for a closed system, the existing and opposing forces must be equal. That is, the operator or by automatic machine should be perfect complex steps and settings to achieve the equilibrium position.

The first of these shortcomings in known from the same source [2] engraving device containing a stepper motor, the control winding with which the control unit receives control pulses. On the motor shaft mounted rocker with the working tool at the end. The top and bottom of the arm parallel to its axis fixed first disk permanent magnets, in parallel with the second permanent magnets. The second magnets placed on the adjusting elements, which are fixed to the body. In the case also fixed the motor (the stator of the motor). The first and second magnets are a differential circuit in the mode of repelling forces (RF patent for the invention №2429139, IPC WV 3/00 (2006/01), 011 [2]).

The disadvantage of this analog is the placement of the first magnets on the yoke at the top and bottom. This placement due to the differences in action of gravity in the systems of the upper and lower pairs of magnets leads to the need for individual adjustment of the distance between the magnets, which complicates the design of the device and its configuration.

Another disadvantage of this remains similar fastening the second magnets of the adjusting elements. It also complicates the design and reduces the reliability of the device.

The third disadvantage of this analogue is the location of the magnets close to the granite stone that increases the likelihood of clogging imagning gap.

The job description.

When using engraving device it freely set on the vertical axis engraving machine. Under the action of gravity engraving device occupies the position on the workpiece surface. When this wheel (13) is mechanically in contact with a processed surface (10).

In the initial position the striker (4) is horizontal and stationary, the force of interaction of the magnets (6, 7, 8, 9) are balanced.

Using a controller on one of the windings of the motor (2) serves the control pulses. The choice of the winding, which serves such pulses as well as pulse duration and distance of the diamond needle (5) from the treated surface (10) is produced depending on the force of the blow, which should make a diamond needle (5) on the treated surface (10). The flow of current in the winding of the motor (2) drives his shaft into rotation (small angle). The striker (4) it also scrolls, and deals diamond needle (5) the impact on the operating surface (10), the cat is Roy from the impact point remains.

The rotation of the striker (4) and moving the fixed magnets (6, 7) leads to the imbalance of forces of interaction of magnets(6, 7, 8, 9). While the resulting interaction force of the magnets (6, 7, 8, 9) tends to return the striker (4) to its original position.

The decay of the pulse control force of the rotation shaft (3) of the motor (2) is reduced to zero, and the resulting interaction force of the magnets (6, 7, 8, 9) returns the striker (4) to its original position.

Thus, from the foregoing that in the present engraving device claimed technical result: "simplifying the design and improving stability" is achieved due to the fact that the engraving device includes a housing with fixed therein stepper motor, the axis of which a drummer with a diamond needle, to which the right and left of the axis of the fixed first and second magnets. The device contains fixed to the housing, the third and fourth magnets, oriented relative to the first and second magnets so that the first and third and second and fourth magnets act on each other pairwise repulsive. While the first and second and third and fourth magnets pairs are oriented relative to each other so that the said repulsive force of their interaction have a component lying in the plane of motion of the striker.

No need to adjust the gap between the magnets reduces the likelihood of breaking up (rosregulirovanie), which would lead to a reduction in the quality of the engraving. In the inventive engraving device does not require manual or adjusting the equilibrium position of the striker.

Industrial applicability.

The author of the engraving device prototype, tests confirmed the achievement of the technical result.

Declare engraving device is realized by application of industrial output devices and materials, can be manufactured at any plant and will find wide application in the field of engraving devices.
