[0026] Example:

[0027] Reference Figure 1 、 Figure 2and Figure 3 As shown, a copper-plated hanger for core large-size gear parts includes a main frame 1, a conductive hook 2 is provided on the top of the main frame 1, and a support assembly is provided inside. The support assembly includes a lower support rod 3 and an upper support rod 4 arranged in parallel, and connecting members 5 are symmetrically provided on the two side walls on opposite sides of the main frame 1. The connecting member 5 passes through the side wall of the main frame 1, and the connecting member 5 and the main frame 1 are insulated. One end of the connecting member 5 located in the main frame 1 is connected to the end of the lower support rod 3, and the other end is fixed with a conductive rod 12. A conductive connecting rod 13 is provided between the conductive rods 12 on both sides of the main frame 1, and a conductive belt 14 is provided on the conductive connecting rod 13; the upper support rod 4 is located above the lower support rod 3, and its two ends are fixed on the main frame 1, and an annular fixing frame 8 is provided on it, and a plurality of positioning rods 9 are provided on the fixing frame 8; the lower support rod 3 is provided with an electrode rod 7, and one end of the electrode rod 7 passes through the fixing frame 8.

[0028] The conductive hook 2 is used to facilitate the hanger to be hung above the electroplating tank and connected to the cathode of the external power supply line. A plurality of positioning rods 9 are installed on the fixing frame 8, and the parts are clamped on the fixing frame 8. The positioning rods 9 support and position the parts, and the end of the upper support rod 4 on which the fixing frame 8 is installed is fixed on the main frame 1. The conductive hook 2 is connected to the main frame 1. After the conductive hook 2 is connected to the cathode, the main frame 1 is also connected to the cathode, and the upper support rod 4 connected to the main frame 1 is also connected to the cathode, so that the fixing frame 8 and the positioning rod 9 are connected to the cathode, and then the parts clamped between the positioning rods 9 are connected to the cathode; and the lower support rod 3 is fixed on the connecting piece 5, and the connecting piece 5 is connected to the main frame 1 The insulation is set between them, so the main frame 1 is connected to the cathode without causing the connector 5 to be connected to the cathode, and the connector 5 is connected to the conductive rod 12, and the conductive rod 12 is connected to the conductive belt 14 through the conductive connecting rod 13. The conductive belt 14 is connected to the anode of the external power supply line, so that the conductive connecting rod 13, the conductive rod 12 and the connector 5 are connected to the cathode, and then the lower support rod 3 is connected to the cathode, so that the electrode rod 7 on the lower support rod 3 is connected to the cathode, and the electrode rod 7 passes through the fixed frame 8. Since the part is stuck on the fixed frame 8, the electrode rod 7 will pass through the core of the part. After power is turned on, the electrode rod 7 is connected to the anode, and the part is connected to the cathode. During electroplating, a copper plating layer can be formed on the surface of the core of the part. The hanger improves the stability of the part in the electroplating tank, does not shake, improves the uniformity and consistency of the formed copper plating layer, and improves the quality of the product.

[0029] A mounting rod 6 is provided on the lower support rod 3 , and one end of an electrode rod 7 is fixed on the mounting rod 6 . The electrode rod 7 is arranged perpendicular to the fixing frame 8 , and the electrode rod 7 is located on the central axis of the fixing frame 8 .

[0030] The electrode rod 7 is perpendicular to the fixing frame 8. Since the part is clamped on the fixing frame 8, the electrode rod 7 is inserted vertically into the core of the part. At the same time, the electrode rod 7 is located on the central axis of the fixing frame 8, so that the electrode rod 7 is also on the central axis of the part. This makes the distance between the electrode rod 7 and the side wall of the part core uniform, further improving the uniformity of the copper plating layer formed on the core. The electrode rod 7 is installed by the mounting rod 6, which facilitates the perpendicular arrangement of the electrode rod 7 and the fixing frame 8.

[0031] A plurality of annular fixing frames 8 are provided on the upper support rod 4 , and connecting rods 10 are provided between adjacent fixing frames 8 . Electrode rods 7 are provided at corresponding positions on the lower support rod 3 , and the fixing frames 8 and the electrode rods 7 are provided in a one-to-one correspondence.

[0032] By providing multiple fixing brackets 8 on the upper support rod 4 and corresponding electrode rods 7 on the lower support rod 3, multiple electroplated parts can be placed on the hanger at the same time, improving work efficiency and facilitating large-scale production and processing. The stability and structural strength of the fixing brackets 8 are enhanced by connecting rods 10.

[0033] The main frame 1 is a rectangular structure with reinforcing ribs 17 provided at its top corners.

[0034] The main frame 1 is configured as a rectangular structure, which facilitates the arrangement of an upper support rod 4 and a lower support rod 3 therein, and reinforcing ribs 17 are provided at the top corners to improve the structural strength of the main frame 1 and prevent the main frame 1 from being deformed due to stress, thereby affecting the relative position of the electrode rod 7 and the fixing frame 8, thereby affecting the uniformity of the copper plating layer, and resulting in reduced product quality or even unqualified products.

[0035] The conductive rod 12 is arranged along the height direction of the main frame 1 , and the conductive connecting rod 13 is arranged at the top end of the conductive rod 12 .

[0036] The conductive rod 12 is connected to the connector 5. Multiple support components can be set on the main frame 1. Then the conductive rod 12 is set along the height direction of the main frame 1, and multiple connectors 5 can be connected at the same time; and a conductive connecting rod 13 is set on the top of the conductive rod 12. Since the fixing frame 8 for placing parts will enter the electroplating pool when in use, the conductive connecting rod 13 is located on the top of the conductive rod 12, so that the conductive connecting rod 13 is located above the electroplating pool, which is convenient for workers to operate the conductive connecting rod 13 and the external power supply line.

[0037] The conductive hook 2 includes a hook 18 , one end of which is fixed to the top of the main frame 1 , and a copper bus 15 is provided on the inner side wall of the end, and a pressing spring 16 is provided on the other end.

[0038] The copper bus 15 is arranged inside the hook 18 to improve the conductivity of the conductive hook 2 , and the contact stability between the external power supply line and the copper bus 15 is ensured by pressing the spring piece 16 , further ensuring the uniformity of the copper plating layer.

[0039] A structural reinforcement rod 11 is further provided between the fixing frame 8 and the upper support rod 4 .

[0040] The structural reinforcement rod 11 is used to improve the strength of the connection structure between the fixing frame 8 and the upper support rod 4. Since parts are placed on the fixing frame 8, the structural reinforcement rod 11 is used to prevent the fixing frame 8 from being deflected downward by the pressure of the parts. At that time, the relative position of the fixing frame 8 and the electrode rod 7 changes, making the distance between the electrode rod 7 and the core of the part uneven, and further making the copper plating layer uneven, affecting the quality of the product.

[0041] A plurality of positioning rods 9 are evenly arranged on the fixing frame 8 .

[0042] The pressure of the parts is evenly distributed on the fixing frame 8 by the evenly arranged positioning rods 9, and the fixing frame 8 is evenly stressed, thereby preventing the fixing frame 8 from being deformed due to uneven stress, resulting in unstable fixation of the parts by the fixing frame 8 and the positioning rods 9, which will cause the position of the parts in the electroplating tank to change, and further make the copper plating layer uneven, thereby affecting the quality of the product.

[0043] During use, the two ends of the upper support rod 4 are welded to the inner wall of the main frame 1, and connecting parts 5 are set through the two side walls of the main frame 1. At the same time, the connecting parts 5 and the main frame 1 are insulated. The two ends of the lower support rod 3 are respectively welded to the connecting parts 5 on both sides, and the conductive rod 12 is welded to the outside of the connecting part 5. The conductive connecting rod 13 is welded and fixed to the top of the conductive rod 12. The conductive belt 14 is connected to the conductive connecting rod 13 by bolts and nuts, and the conductive hook 2 is also connected to the main frame 1 by bolts and nuts. Then, the mounting rod 6 is welded to the lower support rod 3, the electrode rod 7 is welded to the mounting rod 6, the fixing frame 8 is welded to the upper support rod 4, and multiple positioning rods 9 are evenly welded on the fixing frame 8 to complete the hanger assembly. Then the large-sized gear parts with copper-plated cores are clamped on the fixing frame 8, and the positioning rods 9 are pressed against the outer wall of the parts for positioning support. At the same time, the core of the parts are sleeved on the electrode rods 7 to complete the positioning of the parts. Then the hanger is hung above the electroplating tank, and the parts enter the electroplating solution. The conductive hook 2 is hung on the cathode of the external power supply line, so that the conductive hook 2 is connected to the cathode, and then the main frame 1, the upper support rod 4, the fixing frame 8, and the positioning rod 9 are connected to the cathode, so that the copper-plated parts are connected to the cathode, and the conductive belt 1 4 is connected to the anode of the external power supply line, so that the conductive belt 14 is connected to the anode, and then the conductive connecting rod 13, the conductive rod 12, the connecting piece 5, the lower support rod 3, and the mounting rod 6 are connected to the anode, so that the electrode rod 7 is connected to the anode. At this time, in the electroplating tank, the electrode rod 7 is connected to the anode, and the part is connected to the cathode, so that a copper plating layer can be formed on the surface of the part core. The use of this hanger improves the stability of the part position in the electroplating tank and the consistency of the distance between the electrode rod 7 and the part core, thereby improving the uniformity of the copper plating layer and improving the quality of the product.

[0044] In actual use, an insulating layer is provided on the surface of the main frame 1, the upper support rod 4, the lower support rod 3, the fixing frame 8, the conductive connecting rod 13, the conductive rod 12, the connecting piece 5, the mounting rod 6, the reinforcing rib 17, the structural reinforcement rod 11 and the connecting rod 10 to prevent the formation of a copper plating layer on the surface of the above components during electroplating, which wastes resources and increases production costs.

[0045] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model.
