Description

Technical Field

[0001] The present invention relates to the technical field of workpiece painting equipment, and specifically relates to a surface painting device for automobile parts. Background Technique

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. It can be divided into cutting machining and pressure machining according to the difference in machining methods. After machining, the surface of the workpiece needs to be painted to prevent rusting.

[0003] However, when painting the surface of the workpiece, since the position of the spray head is fixed, the paint on the surface of the workpiece will be uneven during painting, which reduces the working quality of the surface painting device.

[0004] At the same time, after spraying the upper surface of the workpiece, the operator needs to manually turn the workpiece over before continuing the processing. This requires turning off the painting device, fixing the workpiece after turning it over, and then continuing to work, which reduces the working efficiency of the surface painting device.

[0005] After painting the workpiece, the operator needs to manually remove the workpiece for collection, which increases the workload of the operator. Summary of the Invention

In this way, the workpiece can be blanked without the operation of the operator, which reduces the workload of the operator.

[0043] Working principle:

[0044] When painting the workpiece after machining:

[0045] Workpiece fixing stage:

[0046] First, the operator places the machined workpiece on the square plate 9. Then, connect the external power supply of the first motor 404 and start the first motor 404. The first motor 404 drives the double-headed stud 405 to rotate. The double-headed stud 405 drives the two clamping plates 406 to move. The clamping plates 406 drive the abutting plate 409 to move through the first slide bar 407. After the abutting plate 409 abuts against the workpiece, the first spring 408 is compressed and the first spring 408 starts to contract. Then, the first motor 404 stops working.

[0047] Workpiece upper surface painting stage:

[0048] Connect the external power supply of the nozzle 506 and start the nozzle 506. The nozzle 506 sprays the paint in the external hose onto the upper surface of the workpiece through the cross beam 505. While the nozzle 506 is working, connect the external power supply of the second cylinder 502 and start the second cylinder 502. The second cylinder 502 drives the bent plate 503 to move. The bent plate 503 drives the second vertical plate 504 to move. The second vertical plate 504 drives the cross beam 505 to move. The cross beam 505 drives the nozzle 506 to move, so that the nozzle 506 can evenly paint the upper surface of the workpiece. After the painting is completed, the nozzle 506 stops working and the second cylinder 502 contracts. In this way, the nozzle 506 evenly paints different positions of the workpiece. After the upper surface of the workpiece is painted, turn off the nozzle 506. Then, the output end of the second cylinder 502 contracts. In this way, the nozzle 506 moves away from above the workpiece. Then, the second cylinder 502 stops working.

[0049] Workpiece lower surface painting stage:

[0050] Connect the external power supply of the first cylinder 401 and start the first cylinder 401. The first cylinder 401 drives the first cross plate 402 to move. The first cross plate 402 drives the T-shaped plate 403 to move. The T-shaped plate 403 drives the abutting plate 409 to move by driving the double-headed stud 405 to move. The abutting plate 409 drives the clamped workpiece to move upward, so that the lower surface of the workpiece leaves the square plate 9. After that, since the spray head 506 is movably connected to the cross beam 505, the operator manually rotates the spray head 506 to make the spray head 506 spray paint upward, and the lower surface of the workpiece is painted through the spray head 506. After the painting is completed, the spray head 506 is closed, and the output end of the first cylinder 401 moves in the reverse direction. The workpiece is placed on the square plate 9 in the above manner. Then, the output shaft of the first motor 404 rotates in the reverse direction, and the abutting plate 409 is moved away from the workpiece in the above manner. Then, the first motor 404 stops working.

[0051] Workpiece blanking stage:

[0052] Connect the external power supply of the third cylinder 8 and start the third cylinder 8. The third cylinder 8 drives the square plate 9 to descend. When the square plate 9 descends to a suitable position and the workpiece descends to the same height as the push plate 704, the third cylinder 8 stops working. Then, connect the external power supply of the second motor 701 and start the second motor 701. The second motor 701 drives the gear 702 to rotate. The gear 702 drives the rack 703 to move. The rack 703 drives the push plate 704 to move on the third slide bar 705 and compresses the second spring 706 at the same time. The push plate 704 pushes the workpiece on the square plate 9 into the collection box 10. Then, the output shaft of the second motor 701 rotates in the reverse direction, and the push plate 704 can be reset in the above manner. Then, the second motor 701 is closed. Then, the output end of the third cylinder 8 resets the square plate 9 in the above manner. Then, the third cylinder 8 stops working, and the surface painting work of the machined workpiece is completed.
