Description

Technical Field

[0001] This utility model relates to the field of electrophoresis tooling technology, and in particular to electrophoresis tooling for automotive sheet metal parts. Background Technology

[0002] Automotive sheet metal parts refer to the metal shell of a car, usually made of steel plates. They are designed to reduce weight as much as possible while ensuring strength. They not only serve a protective and aesthetic purpose, but also withstand air resistance, affecting the car's economy and appearance. The main processes for automotive sheet metal parts include body disassembly and assembly, straightening, repair, and vehicle assembly. During the processing of automotive sheet metal parts, electrophoresis treatment is required using electrophoresis fixtures.

[0003] Patent publication number CN105483801A discloses an electrophoresis fixture for automotive rear axles, belonging to the field of automotive rear axle production.

[0026] By setting up a base 1, mounting bracket 2, servo motor 3, threaded rod 4, slide rod 5, lifting block 6, mounting rod 7, mounting sleeve 8, top rod 9, fixing bolt 10, movable sleeve 11, slider 12, hook 13, insertion rod 14, pull block 15, tension spring 16, cylinder 17, storage rack 18, lifting tool positioning seat 19, and fork hole 20, the electrophoresis fixture is adjustable according to different automotive sheet metal parts. This improves the setting method of electrophoresis fixtures in the existing technology, allowing different automotive sheet metal parts to be electrophoretically treated, saving time and effort, accelerating the processing efficiency of automotive sheet metal parts, and improving the practicality and applicability of the electrophoresis fixture.

[0027] The lower surface of the movable sleeve 11 is provided with an installation component, which includes an installation block 21 and a fixing sleeve 22. The installation block 21 and the fixing sleeve 22 are both fixedly installed on the lower surface of the movable sleeve 11. A fixing plate 23 is fixedly installed on the top of the hook 13. A connecting sleeve 24 is fixedly installed on the upper surface of the fixing plate 23. A positioning block 25 is fixedly installed on the inner wall of the connecting sleeve 24. The connecting sleeve 24 is located between the installation block 21 and the fixing sleeve 22. The side wall of the installation block 21 has a positioning groove that matches the positioning block 25. The side wall of the fixing sleeve 22 is threaded with a positioning bolt 26. The positioning bolt 26 passes through the side wall of the fixing sleeve 22 and the installation block 21. The side wall of the connecting sleeve 24 has a positioning hole for insertion with the positioning bolt 26.

[0028] By setting up the mounting block 21, fixing sleeve 22, fixing plate 23, connecting sleeve 24, positioning block 25 and positioning bolt 26, the function of quickly and conveniently replacing the hook 13 is realized, which improves the installation method of the hook 13 in the prior art. When the hook 13 is damaged after long-term use, it can be quickly disassembled and reassembled, thus facilitating the replacement of the hook 13. On the basis of the original, the practicality of the electrophoresis fixture is further improved.

[0029] Working Principle: When using the electrophoresis fixture to perform electrophoresis treatment on automotive sheet metal parts, the servo motor 3 is started first. When the servo motor 3 runs, it drives the threaded rod 4 to rotate inside the mounting bracket 2, thereby moving the lifting blocks 6. Under the action of the mounting rod 7, the push rod 9, and the sliding rod 5, all four lifting blocks 6 slide downwards inside the mounting bracket 2. Simultaneously, the mounting rod 7 and the push rod 9 drive the hook 13 to descend, making it easier to hang the automotive sheet metal parts. Next, the electrophoresis fixture is adjusted according to the different automotive sheet metal parts. The two fixing bolts 10 are tightened, causing them to extend upwards. When the fixing bolts 10 turn out of the fixing holes, the restriction on the mounting sleeve 8 is released. Then, the two push rods 9 are moved forward or backward, causing the two push rods 9 to drive the two mounting sleeves 8 to move forward or backward on the outer surface of the two mounting rods 7, thus allowing automotive sheet metal parts of different lengths to be hung. When the two mounting rods 7 reach a suitable distance, the two fixing bolts 10 are reversed, causing them to re-insert into the fixing holes. The position of the push rod 9 is fixed by the mounting sleeve 8; pulling the pull block 15 away from the movable sleeve 11 causes the tension spring 16 to stretch and deform, and the insertion rod 14 extends away from the movable sleeve 11. After the insertion rod 14 slides out of the insertion hole, the fixation of the movable sleeve 11 is released. Then, the movable sleeve 11 is pulled to slide on the outer surface of the push rod 9, and the slider 12 slides inside the slide groove, so that automotive sheet metal parts of different widths can be hung. When the movable sleeve 11 drives the hook 13 to the appropriate position, the pull block 15 is released, and the tension spring 16... To restore the position, pull the plug rod 14 by pulling the pull block 15, so that the plug rod 14 is reinserted into the insertion hole, thereby fixing the position of the movable sleeve 11 and the hook 13. Then, the car sheet metal part is hung up by the hook 13. Next, the servo motor 3 is controlled to move in the opposite direction, driving the car sheet metal part to rise. Finally, the cylinder 17 is started and controlled to extend, driving the storage rack 18 to rise. When the storage rack 18 contacts the car sheet metal part, it supports the car sheet metal part. Then, the car sheet metal part can be electrophoretically treated by the electrophoresis fixture.

[0030] When the hook 13 needs to be replaced, tighten the positioning bolt 26 so that the positioning bolt 26 extends away from the fixed sleeve 22. After the positioning bolt 26 is turned out of the positioning hole, the restriction on the connecting sleeve 24 is released. Then, the connecting sleeve 24 is pulled laterally away from the fixed sleeve 22 by the hook 13, so that the connecting sleeve 24 slides inside the fixed sleeve 22 and the positioning block 25 slides inside the positioning groove. When the connecting sleeve 24 is separated from the fixed sleeve 22, the disassembly of the hook 13 is completed. Then, take out the new hook 13 and reverse the above operation to install the new hook 13 onto the movable sleeve 11 to complete the replacement of the hook 13.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
