[0023] In this embodiment, after the worker sets the alloy tube on the base 204, he uses the elasticity of the elastic rod 202 to drive the top fixing block on the top plate 201 to press down on the top of the alloy tube, and fix the alloy tube between the base 204 and the top fixing block; then, the fixed alloy tube is driven downward by the driving component 3 and completely immersed in the electroplating solution in the electroplating tank 101 for electroplating, at which time the pin 8 is inserted into the plug rod 7, and the pin 8 is frictionally connected with the plug rod 7; Starting the pump body 4 drives the plating liquid in the plating tank 101 to flow into the drainage tank 102, and the plating liquid in the drainage tank 102 flows back to the plating tank 101 through the connecting pipe 9, so that the liquid circulates and improves the electroplating effect. In addition, the pressurized plating liquid sprayed by the pump body 4 in the drainage tank 102 will impact the paddle blades and drive the paddle rod 6 to rotate. The rotating paddle rod 6 drives the plug rod 7 to rotate through the latch 8. The rotating plug rod 7 drives the secondary transmission wheel 207 to rotate. The secondary transmission wheel 207 drives multiple groups of main transmission wheels 205 to rotate synchronously through the transmission belt 208, so that the alloy tube clamped between the base 204 and the top fixed block rotates, so that the multiple groups of alloy tubes can rotate in the flowing plating liquid, ensuring that each part of the surface of the alloy tube can obtain consistent metal deposition, thereby further improving the electroplating effect of the alloy tube and reducing the time required for electroplating.

[0024] Preferably, the driving assembly 3 includes an electric slide rail 301, which is fixedly arranged on the side of the operating box 1, and an electric telescopic rod 302 is arranged on the electric slide rail 301. The electric slide rail 301 can drive the electric telescopic rod 302 to move forward and backward, and the top of the electric telescopic rod 302 is fixedly connected to the bottom of the top plate 201; Starting the electric telescopic rod 302 can drive the top plate 201 to move up or down, and the top plate 201 drives the bottom plate 203 to move up or down synchronously through the elastic rod 202, thereby driving the clamped alloy tube to move up or down, so that the alloy tube can be completely moved down and immersed in the electroplating solution for electroplating, or moved up and out of the electroplating solution.

[0025] Preferably, both ends of the electroplating tank 101 are gradually narrowed, and a spoiler rod 1011 is provided on the narrowing surface; the spoiler rod 1011 is specifically an L-shaped rod, and the extension direction of the rod portion is close to the water inlet end of the electroplating tank 101; The pump body 4 can drive the electroplating solution to enter from the left side of the electroplating tank 101 and flow out from the right side of the electroplating tank 101; When the plating solution enters from the liquid inlet end, the flow rate is relatively high due to the small aperture at the inlet, and the flow rate is relatively large at this time; when the liquid flows to the middle part, the aperture gradually increases, and with the increase of the cross-sectional area, the flow rate gradually decreases, and the flow rate reaches the lowest point in the middle area; when moving from the middle area to the other end, the flow rate will increase again; by gradually shrinking the two ends of the electroplating tank 101 and through the spoiler rod 1011, the flow rate is changed by utilizing the contraction angle of the tank wall and the spoiler rod 1011, the liquid impacting the spoiler rod 1011 will change the flow rate of part of the liquid, so that the liquid flow is separated to form a vortex or turbulence, and the turbulence can effectively mix the plating solution, so that the metal ions are more evenly distributed in the entire solution, reducing the concentration polarization phenomenon, and ensuring that all parts of the alloy tube surface can obtain consistent metal deposition.

[0026] Preferably, two groups of limit rods 5 are provided on the top of the operation box 1, and the two groups of limit rods 5 are symmetrically arranged at both ends of the electroplating tank 101, and the limit rods 5 are in an inverted L shape to limit the bottom plate 203 from being moved out of the operation box 1; The elastic rod 202 includes a sleeve rod 2021, the bottom of which is fixedly arranged on the top of the bottom plate 203, a movable rod 2022 is slidably sleeved on the inner circumference of the sleeve rod 2021, the top of the movable rod 2022 is fixedly arranged on the bottom of the top plate 201, a spring 2023 is arranged inside the sleeve rod 2021, the top of the spring 2023 is fixedly connected to the bottom of the movable rod 2022, and the bottom of the spring 2023 is fixedly connected to the sleeve rod 2021; By means of the limit rod 5, when the driving assembly 3 drives the top plate 201 to move up to the top, the elastic rod 202 first uses its own elasticity to drive the bottom plate 203 and the top plate 201 to move up synchronously. When the two ends of the bottom plate 203 abut against the limit rod 5, the bottom plate 203 is limited and fixed by the limit rod 5, and the top plate 201 continues to move up. The spring 2023 in the elastic rod 202 is stretched and deformed to generate energy storage, and the top fixing block is separated from the alloy tube. When the top plate 201 moves up to the top, the top fixing block is completely separated from the alloy tube, which is convenient for workers to take the alloy tube out of the base 204. Similarly, when the worker places another set of alloy tubes on the base 204, the top plate 201 is driven downward by the driving assembly 3. When the top plate 201 moves downward and abuts the alloy tube, the spring 2023 releases the stored energy, and the bottom plate 203 keeps its position, while the top plate 201 continues to move downward. When the top plate 201 abuts the alloy tube, the top plate 201 drives the alloy tube and the bottom plate 203 to move downward synchronously through the action of the alloy tube on the bottom plate 203, until they are completely immersed in the electroplating solution for electroplating. This meets the use requirements of alloy tubes of different lengths and improves the practicality of the device.

[0027] Preferably, at least two groups of soft rubber balls are equidistantly arranged at the bottom of the outer edge of the limiting rod 5, and hard rubber balls are symmetrically arranged at both ends of the top of the bottom plate 203; The front side of the notch of the electroplating tank 101 is provided with a chamfer for drainage; When the top plate 201 moves up to the top, the top fixing block is completely separated from the alloy tube, and the driving assembly 3 drives the top plate 201 to move forward to get closer to the workers, so that the workers can take or place the alloy tube from the bottom plate 203; in the process of the top plate 201 moving forward, the top plate 201 drives the bottom plate 203 to move forward through the elastic rod 202, and the hard rubber ball on the bottom plate 203 will cause the bottom plate 203 to move down when it moves to the soft rubber ball, and will cause the bottom plate 203 to move up when it moves out of the soft rubber ball, thereby causing the bottom plate 203 to move up and down slightly in the process of moving forward along the limit rod 5, and the liquid remaining on the alloy tube will be vibrated and drained into the notch and chamfer of the electroplating tank 101.

[0028] Preferably, a rubber sleeve is provided on the top of the latch pin 8 to increase the friction force, thereby increasing the friction force between the latch pin 8 and the insertion rod 7, thereby improving the transmission of the latch pin 8 to the insertion rod 7.

[0029] Preferably, a nickel plate is provided on the front wall of the inner cavity of the electroplating tank 101, and the nickel plate is electrically connected to the anode of the external power supply; the top plate 201 is electrically connected to the cathode of the external power supply, and the main transmission wheel 205 and the main fixing block are both made of conductive materials; During electroplating, the anode of the external power supply energizes the nickel plate in the electroplating tank 101, and the cathode of the external power supply energizes the top plate 201. When the top plate 201 drives the top fixed block to abut against the alloy tube, the cathode current on the top plate 201 flows into the alloy tube, charging the alloy tube, thereby starting the electroplating operation.

[0030] A nickel plating method for an alloy tube nickel plating device comprises the following steps: S1. Placing the alloy tube: The worker sets the alloy tube to be electroplated on the base 204; uses the elasticity of the elastic rod 202 to drive the top fixing block on the top plate 201 to press down on the top of the alloy tube, and fixes the alloy tube between the base 204 and the top fixing block; drives the fixed alloy tube to move downward through the driving component 3, so that it is completely immersed in the electroplating solution in the electroplating tank 101; S2, start the pump body 4: start the pump body 4, so that the electroplating liquid in the electroplating tank 101 flows into the drainage tank 102 through the connecting pipe 9, and then flows back into the electroplating tank 101, forming a liquid circulation flow; S3, the transmission system works: the pressurized electroplating liquid sprayed by the pump body 4 in the drainage groove 102 will impact on the blade, driving the blade rod 6 to rotate; the rotating blade rod 6 drives the plug rod 7 to rotate through the latch 8; the plug rod 7 drives the auxiliary transmission wheel 207 to rotate, and the auxiliary transmission wheel 207 drives multiple sets of main transmission wheels 205 to rotate synchronously through the transmission belt 208; the main transmission wheel 205 drives the top fixing block to rotate, so that the alloy tube clamped between the base 204 and the top fixing block rotates; S4, electroplating operation: the anode of the external power supply energizes the nickel plate in the electroplating tank 101, and the cathode of the external power supply energizes the top plate 201; when the top plate 201 drives the top fixing block to abut against the alloy tube, the cathode current on the top plate 201 flows into the alloy tube, charging the alloy tube, and the electroplating operation begins.

Placing the alloy tube: a worker sets the alloy tube to be electroplated on the base (204); uses the elasticity of the elastic rod (202) to drive the top fixing block on the top plate (201) to press down on the top of the alloy tube, and fixes the alloy tube between the base (204) and the top fixing block; drives the fixed alloy tube to move downward through the driving component (3), so that it is completely immersed in the electroplating solution in the electroplating tank (101); S2, start the pump body (4): start the pump body (4), so that the electroplating liquid in the electroplating tank (101) flows into the drainage tank (102) through the connecting pipe (9), and then flows back into the electroplating tank (101), forming a liquid circulation flow; S3, the transmission system works: the pressurized electroplating liquid ejected from the pump body (4) in the drainage groove (102) impacts the blade, driving the blade rod (6) to rotate; the rotating blade rod (6) drives the insertion rod (7) to rotate through the latch (8); the insertion rod (7) drives the auxiliary transmission wheel (207) to rotate, and the auxiliary transmission wheel (207) drives multiple sets of main transmission wheels (205) to rotate synchronously through the transmission belt (208); the main transmission wheel (205) drives the top fixing block to rotate, thereby causing the alloy tube clamped between the base (204) and the top fixing block to rotate; S4, electroplating operation: the anode of the external power supply energizes the nickel plate in the electroplating tank (101), and the cathode of the external power supply energizes the top plate (201); when the top plate (201) drives the top fixing block to abut against the alloy tube, the cathode current on the top plate (201) flows into the alloy tube, making the alloy tube charged, and the electroplating operation begins.
