Description

Technical Field

[0001] This invention relates to the field of workpiece weld grinding technology, specifically to an automatic workpiece weld grinding device. Background Technology

[0002] A weld is a seam formed by melting and connecting the welding rod and the metal at the joint using the high temperature of the welding heat source. After the weld metal cools, the two welded parts are connected into a whole. Depending on the shape of the weld metal and the relative positions of the welded parts, welds are classified as butt welds, fillet welds, plug welds, and electric riveting welds.

[0003] After the workpiece is welded, the weld seam needs to be ground by a grinding device to improve the appearance of the workpiece. In traditional workpiece weld seam grinding operations, the weld seam is mostly processed by hand-held grinding equipment, or semi-automatic grinding equipment is used to clamp and fix the workpiece. The clamping of the workpiece by traditional grinding equipment often requires the worker to manually adjust the clamping device, which is cumbersome. Moreover, after the workpiece is fixed, the worker needs to manually disassemble, flip and refix the workpiece to complete the grinding of multiple weld seams, which affects the overall grinding efficiency.

[0020] The present invention has the following beneficial effects:

[0021] When the elastic telescopic frame of this invention moves, it pushes the limiting ring to move. The limiting ring then fits around the outer end of the workpiece.

The stabilizing plate clamps and fixes the workpiece on all four sides, improving the stability of the workpiece during weld grinding. The workpiece is clamped and fixed by extrusion, which is convenient and does not require the worker to manually adjust the clamping device to fix the workpiece.

[0023] When the power device of this invention drives the threaded rod to rotate, the threaded rod will push the moving plate to slide inside the frame through the telescopic frame. The moving plate supports the telescopic frame, improving the stability of the telescopic frame's support for the grinding wheel. When the moving plate slides, it will adjust the position of the grinding wheel so that the grinding wheel can quickly correspond to the weld seam of the workpiece, thereby improving the grinding efficiency of the workpiece.

[0024] After the worker places the workpiece on top of the support platform, the drive device is activated to rotate the screw inside the slide plate. During operation, the screw pushes the slider to slide inside the slide plate. As the slider moves, it pushes the circular groove plate to move through the electric telescopic plate. At this time, the support platform transports the workpiece to the bottom of the frame for weld grinding. The support platform supports the center of the workpiece, and the two ends of the workpiece are suspended in the air so that the rotating ring can clamp and fix the workpiece, improving the convenience of loading and unloading the workpiece.

A driver 16 is fixedly connected to the surface of the fixing cover 15. The output end of the driver 16 is fixedly connected to the surface of the gear 17. When the elastic telescopic frame 13 of the present invention moves... The limiting ring 14 will be moved, and when it moves, it will be placed on the outer end of the workpiece. At this time, the stabilizing component 6 in the limiting ring 14 will be clamped and fixed by the pressure, which improves the convenience of loading the workpiece. The elastic telescopic frame 13 is slidably connected to the surface of the bearing plate 11, and the bearing plate 11 supports the limiting ring 14, which improves the stability of the limiting ring 14 when supporting the workpiece. When unloading, the limiting ring 14 will be pulled apart from the workpiece by extending the bidirectional electric push rod 12, which completes the unloading operation of the workpiece and improves the convenience of loading and unloading the workpiece.

[0046] The end of the bidirectional electric actuator 12 passes through the frame 10 and extends to the outer end of the frame 10. There are two elastic telescopic frames 13, which are symmetrically arranged with the frame 10 as the center. The inner wall of the elastic telescopic frame 13 is slidably connected to the surface of the bearing plate 11. The center of the end of the elastic telescopic frame 13 corresponds to the center of the limiting ring 14. The lower surface of the gear 17 extends into the interior of the limiting ring 14.

[0047] The stabilizing component 6 includes a grooved ring 21, the surface of which is rotatably connected to the inner wall of the limiting ring 14, and the inner wall of which is fixedly connected to the surface of the rotating ring 22. A pressing frame 20 is rotatably connected to the surface of the elastic telescopic frame 13, and a sliding hole frame 24 is fixedly connected to the end of the pressing frame 20 away from the elastic telescopic frame 13. A force-bearing frame 26 is fixedly connected to the surface of the rotating ring 22. The inner wall of the sliding hole frame 24 is slidably connected to the inner wall of the sliding hole plate 25. When the elastic telescopic frame 13 retracts, it presses the sliding hole plate 25 through the connection between the pressing frame 20 and the sliding hole frame 24. Under the pressure of the sliding hole plate 25, the stabilizing plate 23 retracts towards the center of the limiting ring 14. At this time, the stabilizing plate 23 clamps and fixes the workpiece. The stabilizing plate 23 clamps and fixes the workpiece on all four sides, improving the stability of the workpiece during weld grinding. The workpiece is clamped and fixed by pressing, which is convenient and eliminates the need for manual adjustment of the clamping device by the worker.

[0048] The surface of the rotating ring 22 contacts the inner wall of the limiting ring 14, the surface of the gear 17 is rotatably connected to the inner wall of the groove ring 21, the surface of the limiting ring 14 is provided with four stabilizing plates 23, the four stabilizing plates 23 are arranged circumferentially around the limiting ring 14, and the ends of the four stabilizing plates 23 away from the limiting ring 14 are arranged close to each other, and the force-bearing frame 26 is located at the end of the rotating ring 22 close to the elastic telescopic frame 13.

[0049] The grinding component 7 includes a movable plate 30, the end of which is slidably connected to the inner wall of the frame 10. A telescopic frame 36 is fixedly connected to the bottom of the movable plate 30. A power unit 32 is fixedly connected to the inner wall of the frame 10. A threaded rod 31 is fixedly connected to the output end of the power unit 32. A bearing hole 38 is provided at the bottom of the telescopic frame 36. An adapter plate 39 is slidably connected to the inner wall of the bearing hole 38. The bottom of the adapter plate 39 is fixedly connected to the top of the protective cover 33.

The upper surface of the telescopic frame 36 is fixedly connected to an electric rod 35, and the telescopic end of the electric rod 35 is fixedly connected to the lower surface of the telescopic frame 36. When the starting power device 32 drives the threaded rod 31 to rotate, the threaded rod 31 will push the moving plate 30 to slide inside the frame 10 through the telescopic frame 36. The moving plate 30 supports the telescopic frame 36, improving the stability of the telescopic frame 36 in supporting the grinding wheel 34. When the moving plate 30 slides, it will adjust the position of the grinding wheel 34 so that the grinding wheel 34 can quickly correspond to the weld seam of the workpiece, thereby improving the grinding efficiency of the workpiece.

[0050] The end of the threaded rod 31 away from the power unit 32 is rotatably connected to the inner wall of the frame 10, and the surface of the threaded rod 31 is threadedly connected to the inner wall of the telescopic frame 36.

[0052] The feeding component 8 includes a support platform 51, the bottom of which is fixedly connected to the top of a circular groove plate 50. A storage rack 59 is fixedly connected to the bottom of the circular groove plate 50. A grooved filter rack 58 is slidably connected to the inner wall of the storage rack 59. A water pump 57 is connected to the lower surface of the storage rack 59. A support pipe 56 is connected to the end of the water pump 57 away from the storage rack 59. A spray rack 55 is connected to the end of the support pipe 56 away from the water pump 57. A recovery hole 52 is provided on the top of both the circular groove plate 50 and the top of the support platform 51. The worker places the workpiece on the support platform. After the top of 51 is reached, the drive device 4 is activated to drive the screw 3 to rotate inside the slide plate 2. During operation, the screw 3 will push the slider 54 to slide inside the slide plate 2. When the slider 54 moves, it will push the circular groove plate 50 to move through the electric telescopic plate 53. At this time, the support table 51 will transport the workpiece to the bottom of the frame 10 for weld grinding. The support table 51 supports the center of the workpiece. At this time, both ends of the workpiece will be suspended so that the rotating ring 22 can clamp and fix the workpiece, improving the convenience of loading and unloading the workpiece.

[0053] The surface of the slider 54 is slidably connected to the inner wall of the slide plate 2. The end of the slide plate 2 is fixedly connected to the drive device 4. The output end of the drive device 4 is fixedly connected to the screw 3. The end of the screw 3 away from the drive device 4 extends into the interior of the slide plate 2. The surface of the screw 3 is threadedly connected to the inner wall of the slider 54. The support platform 51 and the circular groove plate 50 are connected to the storage rack 59 through the recycling hole 52. The end of the groove filter rack 58 passes through the storage rack 59 and extends to the outer end of the storage rack 59. The spray rack 55 is located above the support platform 51.

[0054] In use, after placing the workpiece above the feeding component 8, the workpiece is transferred to the bottom of the frame 10 by the feeding component 8. At this time, when the bidirectional electric push rod 12 is activated to move closer to each other, the bidirectional electric push rod 12 will push the elastic telescopic frame 13 to move towards the center of the frame 10. When the elastic telescopic frame 13 moves, it will push the limiting ring 14 to move. When the limiting ring 14 moves, it will fit around the outer end of the workpiece. At this time, the stabilizing component 6 in the limiting ring 14 will be under pressure and clamp and fix the workpiece, improving the convenience of loading the workpiece. The elastic telescopic frame 13 is slidably connected to the surface of the bearing plate 11, and the bearing plate 11 supports the limiting ring 14, improving the stability of the limiting ring 14 when supporting the workpiece. When unloading, the limiting ring 14 will be pulled apart from the workpiece by the extension of the bidirectional electric push rod 12, thus completing the unloading operation of the workpiece and improving the convenience of loading and unloading the workpiece.

[0055] When the limiting ring 14 moves, it drives the rotating ring 22 to fit onto the surface of the workpiece via the grooved ring 21. As the limiting ring 14 continues to move, the end of the workpiece contacts the surface of the force-bearing frame 26. At this point, the limiting ring 14 and the rotating ring 22 will not move due to the workpiece's limitation. The elastic telescopic frame 13 begins to retract under the operation of the bidirectional electric push rod 12. During retraction, the elastic telescopic frame 13 presses against the sliding hole plate 25 through the connection between the pressing frame 20 and the sliding hole frame 24. Under the pressure of the sliding hole plate 25, the stabilizing plate 23 retracts towards the center of the limiting ring 14, thus clamping and fixing the workpiece. Plate 23 clamps and fixes the workpiece on all four sides, improving the stability of the workpiece during weld grinding. The workpiece is clamped and fixed by extrusion, which is convenient and does not require manual adjustment of the clamping device by the worker. When the workpiece needs to be flipped, the driver 16 is started to drive the gear 17 to start working. When the gear 17 is working, it drives the groove ring 21 to rotate inside the limit ring 14. When the limit ring 14 rotates, it drives the workpiece to rotate through the stabilizing plate 23, thereby flipping the workpiece so that the grinding component 7 can grind multiple sides of the workpiece, improving the grinding efficiency of the workpiece weld.

[0056] After the workpiece is fixed, the electric lever 35 is activated to push the telescopic frame 36 downwards. The telescopic frame 36 supports the protective cover 33, improving the stability of the grinding wheel 34 during grinding. The distance between the grinding wheel 34 and the workpiece is adjusted using the telescopic frame 36, allowing the grinding wheel 34 to grind welds of workpieces of different thicknesses. When the power unit 32 is activated to rotate the threaded rod 31, the threaded rod 31 pushes the moving plate 30 to slide inside the frame 10 via the telescopic frame 36. The moving plate 30 supports the telescopic frame 36, improving the stability of the telescopic frame 36's support for the grinding wheel 34. When the moving plate 30 slides, it will impact the grinding wheel 34. The position of 4 is adjusted so that the grinding wheel 34 can quickly correspond to the weld of the workpiece, improving the grinding efficiency of the workpiece. The motor 40 is started to drive the grinding wheel 34 to rotate. The grinding wheel 34 is used to grind the weld of the workpiece. When the electric push rod 37 is started to retract or extend, the electric push rod 37 will push the adapter plate 39 to slide inside the bearing hole 38. When the adapter plate 39 moves, it pushes the grinding wheel 34 to move on the surface of the workpiece through the protective cover 33, so that the grinding wheel 34 can better grind the weld of the flat workpiece, improve the grinding range of the grinding wheel 34, and avoid the situation that the grinding wheel 34 cannot grind after the workpiece is fixed.

[0057] After the worker places the workpiece on top of the support platform 51, the drive device 4 is activated to drive the screw 3 to rotate inside the slide plate 2. During operation, the screw 3 pushes the slider 54 to slide inside the slide plate 2. As the slider 54 moves, it pushes the circular groove plate 50 to move via the electric telescopic plate 53. At this time, the support platform 51 transports the workpiece to the bottom of the frame 10 for weld grinding. The support platform 51 supports the center of the workpiece, and at this time, both ends of the workpiece are suspended in the air so that the rotating ring 22 can grind the workpiece. The clamping and fixing mechanism improves the convenience of loading and unloading workpieces. When the workpiece is being polished, the water pump 57 will transfer the polishing fluid in the storage rack 59 to the support pipe 56. The polishing fluid will be sprayed onto the surface of the workpiece using the spray rack 55 to avoid high temperature during weld polishing. The impurities generated during polishing will flow into the recovery hole 52 along with the sprayed polishing fluid. The impurities will be centrally processed by the groove filter rack 58. After the groove filter rack 58 is pulled out from the storage rack 59, the impurities can be centrally recovered.
