For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be an electrical connection; it can be a hydraulic oil circuit connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0025] Refer to Figures 1-5As shown in the figure, a plating jig for a plate-shaped metal part provided by the utility model includes a suspension rod 1. The suspension rod 1 is made of a cylindrical insulating material and has a certain length. A chuck 2 is connected to the lower end of the suspension rod 1. The chuck 2 is used to fix the plate-shaped metal part, so that the workpiece will not move or shake during the processing. A central hole 11 is provided inside the suspension rod 1. The central hole 11 extends along the length direction of the suspension rod 1 and penetrates the suspension rod 1. The plate-shaped metal part can be clamped by the chuck 2, and then the plate-shaped metal part is completely immersed in the plating solution to achieve electroplating.

[0026] The above-mentioned chuck 2 and the suspension rod 1 are detachably connected. The chuck 2 includes a reference part 21 and a clamping part 24. Both the reference part 21 and the clamping part 24 are made of insulating materials. The reference part 21 includes a plate body and a sleeve 28. The sleeve 28 is made of insulating material. The sleeve 28 is fixed to the upper end of the plate body, and the sleeve 28 can be inserted into the central hole 11 on the suspension rod 1 to realize the connection between the chuck 2 and the suspension rod 1.

[0027] The reference part 21 is a rectangular plate suitable for the plate-shaped metal part. A cavity is provided inside the reference part 21. Two rows of round holes are provided on the surface of the reference part 21 opposite to the clamping part 24, with 6 round holes in each row. A long strip-shaped metal disk 22 is provided in the cavity inside the reference part 21. The metal disk 22 has a certain thickness. Two rows of threaded holes are arranged in an array on the metal disk 22, with 6 threaded holes in each row. The threaded holes on the metal disk 22 correspond to the round holes on the reference part 21. The threaded holes completely penetrate the metal disk 22. A metal column 23 can be connected to the reference part 21. The metal column 23 is used to clamp the plate-shaped metal part. The metal column 23 is made of a conductive material such as iron or copper. One end of the metal column 23 passes through the round hole and enters the cavity inside the reference part 21. At this time, an external thread is provided at the end located in the cavity. The other end of the metal column 23 is located outside the reference part 21, and then the end with the external thread is screwed with the threaded hole on the metal disk 22. By rotating the metal column 23, the metal column 23 is docked on the metal disk 22, so that the metal column 23 forms a conveniently detachable connection. In this way, when electroplating metal plates of different materials, only the metal column 23 of different materials needs to be replaced, which is more convenient. The end of the metal column 23 extending out of the reference part 21 is used to contact the plate-shaped metal plating part. A support rod 29 is also fixedly connected to the lower end of the reference part 21. It is located in the middle of the reference part and extends downward. The support rod 29 is an L-shaped insulating cylindrical rod. During the electrolysis process, the support rod 29 can provide a support and fixing function for the plate-shaped metal part, so that the plate-shaped metal part will not move or shake during the processing. To increase the scope of application, the support rod 29 can also be set as a telescopic structure.

[0028] The above-mentioned clamping part 24 is also plate-shaped. Threaded holes are provided on the clamping part 24, which completely penetrate the clamping part 24. A metal screw 25 is screwed onto the threaded holes. It should be noted that the metal screw 25 on the clamping part 24 corresponds to the metal column 23 on the reference part 21, so as to ensure uniform force and stable clamping during the clamping process of the plate-shaped metal part. The clamping part 24 and the reference part 21 are hinged by a pin shaft. When a pressing force is applied to one end of the clamping part 24, the other end moves upward. At this time, the plate-shaped metal part can be placed between the clamping part 24 and the reference part 21, and then the pressing on the clamping part 24 is released. An arched elastic rod 26 is connected between the clamping part 24 and the reference part 21. The elastic rod 26 provides elastic support for the clamping part 24 and the reference part 21. Under the action of the restoring force of the elastic rod 26, the metal screw 25 on the clamping part 24 and the metal column 23 on the reference part 21 contact the plate-shaped metal part, and the plate-shaped metal part is clamped by the chuck 2 at this time.

[0029] The upper end of the hanging rod 1 is connected with a winding reel 3. The winding reel 3 includes a circular disc and a handle 33. A winding core shaft 31 is provided at the center of the circular disc 32. The wire 4 is wound around the winding core shaft 31. The side edge position of the circular disc 32 is connected with a folding handle 33. The surface of the folding handle 33 has protruding textures to increase the friction between the hand and the folding handle 33 and prevent the folding handle 33 from slipping during operation.

[0030] The central hole 11 inside the above-mentioned hanging rod 1 can be used as the passage for the wire 4, enabling the wire 4 to pass through the hanging rod 1, which avoids the random distribution of the wire 4 in space and reduces the possibility of the wire 4 being damaged. After the wire 4 passes through the central hole 11, it continues to pass through the sleeve 28. An extension hole is provided on the reference part 21, which extends from the upper end of the reference part 21 to the cavity. After the wire passes through the sleeve 28, it is guided into the extension hole and finally the wire is docked with the metal disc 22. Therefore, the winding and unwinding of the wire 4 by the winding reel 3 can control the vertical adjustment of the chuck.

[0031] When the chuck 2 moves vertically downward, the winding reel 3 needs to perform a wire unwinding operation. Under the influence of gravity, the reference part 21 moves downward. The wire 4 is connected to the reference part 21 and is continuously released from the winding core shaft 31 on the winding reel 3. At this time, the upper end of the sleeve 28 gradually moves out of the central hole 11 on the hanging rod 1, controlling the downward movement of the chuck 2 and the plate-shaped metal part, so that the chuck 2 and the plate-shaped metal part are all immersed in the electroplating solution. When the chuck 2 needs to move vertically upward, the folding handle 33 can be shaken to rotate the winding reel 3 to provide power for the retraction of the wire 4, so that the wire 4 winds around the winding core shaft 31 on the winding reel 3, realizing the wire retraction operation and taking the chuck 2 and the plate-shaped metal part out of the electroplating solution to realize the vertical upward adjustment of the chuck 2 and the plate-shaped metal part.

[0032] At the vertical middle position of the suspension rod 1, a short connection sleeve 12 is also fixed. The short connection sleeve 12 is also made of cylindrical insulating material. A threaded hole is provided at the central axis of the short connection sleeve 12. A conductive top rod 13 is screwed into the short connection sleeve 12. An external thread is provided on the conductive top rod 13. The short connection sleeve 12 and the conductive top rod 13 are docked by means of threaded connection. The conductive top rod 13 can move axially when being screwed. The conductive top rod 13 is composed of a rod body and a contact end. The rod body of the conductive top rod 13 is made of a metal material with good electrical conductivity and is cylindrical in shape. The contact end of the conductive top rod 13 is located at one end of the rod body. An insulating layer is wrapped around the outside of the conductive top rod 13 to prevent current leakage and short circuit. Move the conductive top rod 13 close to the short connection sleeve 12 so that the threaded part of the conductive top rod 13 is aligned with the threaded hole of the short connection sleeve 12. When the conductive top rod 13 and the short connection sleeve 12 are aligned, start applying a rotational force to make the conductive top rod 13 continuously enter the short connection sleeve 12 until the inner end of the conductive top rod 13 passes through the short connection sleeve 12 and enters the central hole 11 on the suspension rod 1. The inner end of the conductive top rod 13 starts to contact the wire 4 in the central hole 11. Continue to apply a rotational force, and the conductive top rod 13 pushes the wire 4 towards the inner wall of the central hole 11 until the conductive top rod 13 presses the wire 4 against the inner wall of the central hole 11. At this time, the wire 4 can no longer move downward, forming the positioning of the reference part 21. Then, the conductive top rod 13 can be connected to the negative or positive pole of the power supply.

[0033] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
