DETAILED DESCRIPTION

[0023] The following will be combined with the drawings of the specification 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 of 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.

[0025] Specifically, the rotating button 3 is used to drive the bidirectional threaded column 2 to rotate inside the U-shaped clamp 1. By rotating the bidirectional threaded column 2, the upper clamping column 6 fixedly connected to the lower surface of the upper clamping block 5 is driven to slide into the inner wall of the upper clamping groove 11, and the lower clamping column 8 fixedly connected to the upper surface of the lower clamping block 7 is driven to slide into the inner wall of the lower clamping groove 12. The U-shaped clamp 1 and the first pad 9 can be firmly fixed together to form an integral structure, further improving the stability of the processed workpiece. During the electrophoretic coating process, the processed workpiece needs to be kept in the electric field for a long time. The second pad 17 and the clamping block 16 cooperate with each other to provide necessary support for the clamped workpiece, which helps to ensure that the coated object does not deform or move. The shape and design of the circular turntable 15 make them easy to operate. They can be easily rotated by the palm of your hand without additional force or tools, thereby prompting the clamping block 16 and the second pad 17 to cooperate with each other to achieve support and fixation of the workpiece.

[0026] Reference Figure 1 The outer wall of the second pad 17 is fixedly connected to a fixing seat 19, and the inner wall of the fixing seat 19 is fixedly connected to a wire clamping barrel 20;

[0027] Specifically, the second pad 17 can fix the fixing seat 19 , and the fixing seat 19 can fix the wire clamping barrel 20 .

[0028] Reference Figure 1 and Figure 4 The interior of the wire clamping barrel 20 is fixedly connected with a fixing column 21, and the outer wall of the fixing column 21 is rotatably connected with a pressing plate 22; the interior of the wire clamping barrel 20 is fixedly connected with a fixing ring 23, and the upper surface of the fixing ring 23 is fixedly connected with a cylindrical barrel 24; the top of the cylindrical barrel 24 is fixedly connected with a spring 25, and the outer wall of the spring 25 is slidably connected to the inner wall of the cylindrical barrel 24; the bottom end of the spring 25 is fixedly connected to the upper surface of the pressing plate 22, and the lower surface of the pressing plate 22 is fixedly connected with a connecting column 26; the lower surface of the connecting column 26 is fixedly connected with a wire clamping block 27;

[0029] Specifically, the fixed column 21 has a rotational effect on the pressing plate 22. Pressing the pressing plate 22 can cause the fixed column 21 to rotate on the outer wall of the fixed column 21. The spring 25 has a movement and reset effect on the connecting column 26 and then moves and resets the wire clamping block 27. When the pressing plate 22 rotates on the outer wall of the fixed column 21, it will cause the other part of the pressing plate 22 to press the spring 25 to slide on the inner wall of the cylindrical tube 24 and shrink. When the pressing plate 22 presses the spring 25 to slide on the inner wall of the cylindrical tube 24, it will also drive the connecting column 26 to move upward and then drive the wire clamping block 27 to move upward to leave a gap. When the pressing plate 22 is released, the spring 25 will rebound and push the connecting column 26 to reset, thereby driving the wire clamping block 27 to reset and fix the electrical conductor.

[0030] Working principle: when the limiting cathode clamp is needed, first place the outer wall of the first pad 9 to fit the outer wall of the U-shaped clamp 1, rotate the rotating knob 3 to drive the bidirectional threaded column 2 to rotate on the inner wall of the fixed block 4 while also rotating inside the U-shaped clamp 1, when the bidirectional threaded column 2 rotates inside the U-shaped clamp 1, it will cause the upper clamp block 5 to slide on the inner wall of the U-shaped clamp 1 and drive the upper clamping column 6 to move downward, and at the same time, the bidirectional threaded column 2 will also drive the lower clamp block 7 to slide on the inner wall of the U-shaped clamp 1 and drive the lower clamping column 8 to move upward, when the upper clamp block 5 moves, it drives the upper clamping column 6 to completely slide into the inner wall of the upper clamping groove 11 opened on the upper surface of the rectangular block 10, and drives the lower clamping column 8 to completely slide into the lower clamping groove 12 opened on the lower surface of the rectangular block 10. When the first pad 9 needs to be removed, it is only necessary to rotate the rotating knob 3 in the opposite direction to cause the bidirectional threaded column 2 to rotate again inside the U-shaped clamp 1, while causing the upper clamping block 5 to drive the upper clamping column 6 to slide out from the inner wall of the upper clamping groove 11, and at the same time, it will also cause the lower clamping block 7 to drive the lower clamping column 8 to slide out from the inner wall of the lower clamping groove 12. When the upper clamping column 6 completely slides out from the inner wall of the upper clamping groove 11, and the lower clamping column 8 completely slides out from the inner wall of the lower clamping groove 12, the first pad 9 can be quickly disassembled, thereby achieving the effect of quickly installing and disassembling the pad of the limiting cathode clamp, thereby improving production efficiency, reducing maintenance costs, adapting to the needs of different workpieces, and improving operational safety. After the fixation is completed, the second pad 17 is fixed by bolts through the fixing holes 18, and then the circular turntable 15 is rotated to drive the one-way threaded column 14 to rotate inside the fixed cylinder 13, so that the clamping block 16 moves toward the direction of the second pad 17 to clamp the workpiece to be fixed for connecting the workpiece to form an electrical circuit. When the limited cathode clamp needs to be powered, it is only necessary to press the pressing plate 22 to cause it to rotate on the outer wall of the fixed column 21. When the pressing plate 22 rotates on the outer wall of the fixed column 21, it will cause another part of the pressing plate 22 to compress the spring 25 to slide on the inner wall of the cylindrical tube 24 and contract. When the pressing plate 22 compresses the spring 25 to slide on the inner wall of the cylindrical tube 24, it will also drive the connecting column 26 to move upward, thereby driving the wire clamping block 27 upward. Move to leave a gap, then the electric wire can be placed in the inner wall of the wire clamping barrel 20, and the pressing plate 22 is released at the same time after the placement is completed. At this time, the spring 25 rebounds and pushes the connecting column 26 to reset, driving the wire clamping block 27 to reset and fix the electric wire, thereby achieving the effect of quickly connecting the electric wire, which helps to ensure stable current conduction, save connection time, simplify operation steps, improve reliability and applicability, and promote the efficient implementation of the electrophoretic coating process. The limiting cathode clamp based on the electrophoretic process can not only achieve the effect of quickly installing and disassembling the pad of the limiting cathode clamp during use, but also improve production efficiency, reduce maintenance costs, adapt to the needs of different workpieces, and improve operational safety. In addition, it can also achieve the effect of quickly connecting the electric wire.This helps ensure stable current conduction, saves connection time, simplifies operation steps, improves reliability and applicability, and promotes efficient electrophoretic coating process.
