DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-4 An electrophoretic coating fixture in this embodiment includes an electrophoretic pool 1 and an adjusting coating mechanism arranged on the electrophoretic pool 1.

[0033] In this embodiment, the coating adjustment mechanism includes a fixing frame 2 fixedly mounted on the top of the electrothermal pool 1, a servo motor 3 fixedly mounted on the right side of the fixing frame 2, and a rotating rod 4 fixedly mounted on the output shaft of the servo motor 3 and rotatably connected to the inner wall of the fixing frame 2. When in use, the servo motor 3 drives the rotating rod 4 to rotate on the fixing frame 2.

[0034] The coating adjustment mechanism also includes a mounting block 5 fixedly mounted on the outside of the rotating rod 4 and a connecting column 6 fixedly mounted on the front and bottom of the mounting block 5. Specifically, when in use, the mounting block 5 on the rotating rod 4 is driven to rotate by the rotation of the servo motor 3, thereby adjusting the position of the connecting column 6.

[0035] The coating adjustment mechanism also includes a hand-held frame 7 installed on the front of the connecting column 6, a clamping seat 8 fixedly installed on the side of the connecting column 6 away from the mounting block 5, a positioning block 9 fixedly installed inside the clamping seat 8, a bidirectional screw 10 rotatably connected to the inside of the positioning block 9 and extending to the outside of the clamping seat 8, and two movable clamping blocks 11 threadedly connected to both ends of the bidirectional screw 10 and extending to the outside of the clamping seat 8. Two sections of opposite thread grooves are opened on the outside of the bidirectional screw 10, and threaded holes corresponding to the opposite thread grooves are opened inside the movable clamping block 11. Specifically, when the user is in use, the movable clamping block 11 is adjusted on the bidirectional screw 10 according to the size of the workpiece, so as to facilitate better clamping and fixing of the workpiece.

[0036] A first through slot 18 is provided on one side of the clamping seat 8 away from the connecting column 6, and the movable clamping block 11 extends to the outside of the clamping seat 8 through the first through slot 18, so as to facilitate the adjustment of the position of the movable clamping block 11 on the clamping seat 8. The coating adjustment mechanism also includes an anti-skid washer 12 fixedly mounted on the outside of the movable clamping block 11, wherein the anti-skid washer 12 is made of rubber, which increases the friction when in contact with the workpiece, so that the workpiece is fixed more securely.

[0037] In this embodiment, the coating adjustment mechanism also includes an adjustment seat 13 fixedly mounted on the bidirectional screw rod 10. A first through hole 19 is opened on the right side of the clamping seat 8. The bidirectional screw rod 10 extends through the first through hole 19 to the outside of the clamping seat 8 and is fixedly connected to the adjustment seat 13. Specifically, it is convenient for the user to rotate the adjustment seat 13 to drive the bidirectional screw rod 10 to rotate.

[0038] Among them, the adjustment coating mechanism also includes a movable plate 14 slidably connected to the inner wall of the adjustment seat 13, and a first sliding groove 20 is opened on the inner wall of the adjustment seat 13. The movable plate 14 is slidably connected to the inner wall of the adjustment seat 13 through the first sliding groove 20. The movement of the movable plate 14 is restricted by the first sliding groove 20, so that the movement of the movable plate 14 is more stable and smooth.

[0039] Among them, the adjusting coating mechanism also includes a limiting rod 15 fixedly installed on the movable plate 14 and extending to one side of the clamping seat 8. A second through hole 21 is provided on the side of the adjusting seat 13 close to the clamping seat 8, and a limiting groove 22 is provided on the side of the clamping seat 8 close to the adjusting seat 13. The limiting rod 15 extends through the second through hole 21 to the outside of the adjusting seat 13 and is movably connected with the limiting groove 22. The position of the adjusting seat 13 is fixed by the limiting rod 15, thereby preventing the bidirectional screw 10 from rotating arbitrarily and causing the clamped workpiece to fall, which brings inconvenience to production.

[0040] The coating adjustment mechanism further includes a pull rod 16 rotatably mounted on one side of the movable plate 14, a first threaded hole 23 is provided on the side of the adjustment seat 13 away from the clamping seat 8, a threaded section is fixed on the pull rod 16, and the pull rod 16 is threadedly connected to the adjustment seat 13 through the first threaded hole 23. The coating adjustment mechanism further includes a spring 17 fixedly mounted on the side of the movable plate 14 away from the limiting plug rod 15 and sleeved on the outside of the pull rod 16. When in use, the elastic force of the spring 17 applies pressure to the movable plate 14, so that the limiting plug rod 15 is plugged and fixed to the clamping seat 8.

[0041] It should be noted that the electrophoretic coating fixture, through the setting of the adjusting coating mechanism, with the mutual cooperation between the various structures on the electrophoretic tank 1, can clamp and fix another workpiece through another clamping seat 8 when one workpiece is clamped and fixed for electrophoretic coating operation, thereby reducing the time waste caused by the single workpiece coating fixture when replacing the workpiece and the vacancy phenomenon of the electrophoretic tank 1, thereby helping to improve the electrophoretic coating efficiency of the workpiece and enhancing the practical performance of the electrophoretic coating equipment.

[0042] The working principle of the above embodiment is:

[0043] When using the electrophoretic coating fixture, the workpiece is first fixed on the clamping seat 8. The specific fixing operation is as follows: first, pull the pull rod 16 to make the threaded section on the pull rod 16 contact the first threaded hole 23, then rotate the pull rod 16 to make the movable plate 14 drive the limiting plug 15 to disengage from the limiting groove 22 on the clamping seat 8, and then rotate the adjustment seat 13 to drive the bidirectional screw rod 10 to rotate. The rotation of the bidirectional screw rod 10 drives the two movable clamping blocks 11 to move relative to or away from each other according to the size of the workpiece, and the workpiece is clamped and fixed by the movable clamping blocks 11. After the fixing is completed, the servo motor 3 rotates to drive the workpiece into the electrophoretic tank 1 for coating, and the staff repeats the above steps to clamp and fix another workpiece. After the current workpiece enters the electrophoretic tank 1, the previously entered workpiece leaves the electrophoretic tank 1 and is disassembled and replaced with a new workpiece by the staff. This reciprocating cycle can avoid the electrophoretic tank 1 from being idle, thereby helping to improve the efficiency of electrophoretic coating of the workpiece.
