The invention relates to welding, namely, devices for welding when restoring the flat surfaces of worn parts, such as parts of caterpillar tractors.

Known restoration of worn parts lying electrodes that have surfaced on the surface through the insulating layer of the flux and the electrode and the workpiece is connected to the power source (see U.S. Pat. EN 2133177, CL 23 To 9/04, 1999).

However, such welding is limited in scope and is characterized by low productivity.

The closest analogue is a device for welding of a recumbent electrode when restoring worn parts, containing the tabs recreated, current lead and electrode holder with the electrode (see and.with. SU 144925, CL 23 To 9/04, 1961).

This device is unreliable, has limited technological capabilities and are not designed for quick replacement of units, resulting in reduced maneuverability, to the inconvenience of operation and increase the time of repair.

In addition, in the known device does not provide the ability to move the recumbent electrode surfaced along the surface and cannot commit on any Tocco technical solution is to increase mobility and productivity device, the expansion of its technological capabilities while improving facilities operation, improving the quality of the fused surface simplification and increase reliability.

To solve this problem, an apparatus for surfacing a recumbent electrode when restoring worn parts, containing the tabs recreated, current lead and electrode holder with the electrode according to the invention equipped with a rotary table with the frame and consoles, one of which is pivotally mounted on the frame of the table can be rotated about a vertical axis, surfacing cameras and flashbanners, and the electrode holder and facing cameras made in the form of standardized modules, and the electrode holder is mounted on a hinge mounted console, which has the facility consistent fixation of the electrode holder on one of the facing cameras when carrying out welding, and facing the camera evenly placed on the turntable and mounted on the respective brackets, each facing camera has a bottom, the vertical rails and the front and rear movable walls, the front wall of each chamber is installed in the vertical is it mounted on the rear wall of each of the facing cameras and made in the form of fixed and movable brackets, and current lead is made in the form of a graphite plate attached to a fixed bracket, and has a clamping rotary Cam and the screw associated with the Cam, the Cam positioned below the fixed bracket, and the screw is embedded in the rear wall of the chamber can be rotated to clamp the graphite electrical power supply to the part.

In addition, according to the invention console electrode holder has fixed thereto a horizontal guide with the slide on which you installed the electrode holder and the slider includes a screw for pressing the electrode holder.

In Fig.1 shows the proposed device - top view.

In Fig.2 shows the device - side view.

In Fig. 3 shows a section facing camera and shows the location of the electrode holder with a recumbent electrode over facing the camera.

The device comprises a turntable 1 with the frame 11. On the turntable 1 is evenly installed facing camera 2 to host 3 parts. Surfacing camera 2 mounted on the respective brackets 4 of the turntable 1.

Surfacing camera 2 and the electrode holder 5 made in the form of standardized modules for welding of various parts.

Elekta about a vertical axis, for example, using fixed on console 6 and coaxially connected with the frame of the sleeve 61(see Fig.2). Console 6 provided with a means of successive fixation of the electrode holder on one of the facing cameras when carrying out welding.

Each of surfacing camera 2 is made with a movable front wall 8, which is fixed in vertical guides 9 facing camera 2 with an emphasis in the bottom 10. The bottom 10 is tilted to the front wall 8. On the rear wall 11 is provided inside the chamber 2 fixed clamps recreated 3, which are made in the form of movable and fixed brackets 12, 13. On the fixed bracket 13 fixed current lead 14, which is made in the form of a graphite plate. Under the bracket 13 is fixed presser Cam 15, controlled by the screw 16, embedded in the rear wall 11 of the camera can be rotated to compress the graphite plate current supply 14 to the workpiece 3 during welding.

The electrode holder 5 lying electrode 17 is installed on the slider 18, which is located on the horizontal guide 19, which is fixed on the console 6 of the electrode holder 5 and is oriented along the surfaced workpiece surface. The slider 18 is equipped with a screw preload 20 of the electrode holder 5 crept to lusoponte 22 is designed to crumble flux.

The operation of the device.

On the turntable 1 set a set of surfacing cameras 2 and the corresponding electrode holder 5, selected for surfacing of parts 3 of a certain type. Surfacing camera 2 and the electrode holder 5 made in the form of standardized modules, which are designed for the surfacing of a certain type and connected with the rotary table with the possibility of easy replacement. This allows you to increase mobility, improve productivity and expand the technological capabilities of the device.

Surfacing camera 2 is fixed on the consoles 4 rotary table 1, for example, easily detachable threaded connection 21. The electrode holder 5 with the console 6 pivotally secured on the frame 1 of the table can be rotated about a vertical axis, for example, using the installed coaxially to the main frame 11and mounted on the console of the sleeve 61. This is achieved by reducing the time to reinstall sets of modules and increase the convenience of operation.

When the turn table 1 facing camera 2 in series are installed in a working position for welding and repair of worn parts. The electrode holder 5 is mounted above facing camera, ky 2 move upward along vertical guides 9 and remove, and part 3 is installed in the filler chamber 2 on the clamps, which are made in the form of movable and fixed brackets 12, 13 and fixed to the rear wall 11 of the camera. At the turn of the screw 16 and the associated Cam 15 part 3 is pressed tightly to the graphite plate current supply 14. This allows to increase reliability while improving usability.

The bracket 12 is made movable and can change position relative to the fixed bracket 13, which allows you to expand the technological capabilities of the device and allows the surfacing of various sizes.

Then the front wall 8 along the vertical guides 9 of the chamber 2 is lowered all the way down in the bottom 10.

Fixed in the electrode holder 5 recumbent electrode 17 is set over the worn area of the sheet 3. Item 3 is filled with flux to the electrode 17. The electrode 17 is put additional filler metal in powder form, which is the initial part of the electrode 17 is closed with item 3, which allows to provide electrical contact, and facing the camera 2 fill up the flux. After turning on the power source (not shown) between the electrode 17 and the recovered item 3 obrazu Volnoe melting of the electrode 17.

If necessary, eliminate process defects electrode holder with recumbent electrode 17 can be moved and secured by a screw preload electrode holder 20 to slide over the desired point fused surface. For this purpose, the slider 18 is installed on the electrode holder 5, to be moved along the horizontal guide rail 19. This is achieved by improving the quality of welding and increase usability.

After surfacing table 1 turn, facing the camera 2 with the restored item 3 is set to the "cooling-off" and proceed to the surfacing of the following items on the same technology. The following worn parts installed in the other facing the camera 2 and the electrode 5 is set on a plot overlaying the next part. So consistently napravlyayut all the details.

Before groove weld details in each facing the camera on the vertical guides 9 raise the front wall 8, and the flux is easily poured in the bottom 10 in glucovance 22. The screw 16 is embedded in the rear wall 11 of the camera, turn the Cam 15 and free refurbished parts, which are placed in a container (not shown). This is achieved by simplifying the device is worn parts other type enough on the turntable to change the set of unified modules facing cameras and electrode holder kit for other details. When this setting sets the other parts perform exactly the same. This is achieved by increasing the mobility and performance of the device.

Technical and economic effect is to increase mobility and productivity, to enhance its technological capabilities, to simplify and increase operational reliability while improving usability and increasing the quality of welding.
