[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a uniform nickel-gold plating device for precision parts, including an electroplating tank 1, an electroplating mechanism 2 is provided on the upper side of the electroplating tank 1, the electroplating mechanism 2 is used to make the electroplated film more uniform, and a disassembly mechanism 3 is provided on the outer side of the electroplating tank 1, the disassembly mechanism 3 facilitates loading and unloading of parts.

[0035] The electroplating mechanism 2 includes a support plate 21, which is slidably connected to the upper part of the electroplating tank 1. An electric telescopic rod 22 is fixedly connected to the bottom of the support plate 21. When the electric telescopic rod 22 extends downward, it drives the fixed box 23 and the turntable 25 to descend as a whole. The fixed box 23 is fixedly connected to the bottom of the electric telescopic rod 22. A motor 24 is fixedly connected to the inner side of the fixed box 23. The output end of the motor 24 passes through the fixed box 23 and is fixedly connected to a fixing block 31. The fixing block 31 engages with a fixing block 32. A turntable 25 is fixedly connected to the bottom of the fixing block 32. Multiple hooks 26 are fixedly connected to the bottom of the turntable 25 for placing workpieces. The turntable 25 is rotated by the motor 24, which continuously stirs the electroplating solution, thereby making the electroplated film more uniform. Anode components 27 are provided on both the front and rear sides of the inside of the electroplating tank 1. A stirring component 28 is provided at the bottom of the electroplating tank 1. A heating component 29 is provided at the bottom of the inner side of the electroplating tank 1.

[0036] Specifically, electroplating solution is first injected into the electroplating tank 1. The workpiece to be coated is hung on the hook 26 at the bottom of the turntable 25. By engaging the first fixing block 31 and the second fixing block 32, the first electric telescopic rod 22 is activated to extend downward, causing the fixing box 23 and the turntable 25 to descend as a whole. After the motor 24 is started, it drives the first fixing block 31 to rotate through the output shaft, which in turn drives the second fixing block 32 to rotate synchronously with the turntable 25. The rotation of the turntable 25 causes the suspended workpiece to move continuously in the electroplating solution. The anode components 27 on the front and rear sides of the electroplating tank 1 generate an electric field when energized. Under the action of the electric field, the metal ions in the plating solution gather on the surface of the workpiece. After the electroplating is completed, the first electric telescopic rod 22 rises and drives the turntable 25 to detach from the electroplating solution, achieving a more uniform coating effect on the workpiece.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The disassembly mechanism 3 includes a support frame 37, which is fixedly connected to the top outer side of the electroplating tank 1. An electric telescopic rod 36 is fixedly connected to the outer side of the support frame 37. The front end of the electric telescopic rod 36 is fixedly connected to the support plate 21. By activating the electric telescopic rod 36, the support plate 21 is slidably driven, causing the turntable 25 to move outside the electroplating tank 1. A lever 33 is slidably connected inside the first fixing block 31. A transmission rod 35 is rotatably connected to the left and right sides inside the lever 33. A slider 34 is rotatably connected to the outer side of the transmission rod 35. The slider 34 passes through the first fixing block 31 and is fixedly connected to the second fixing block 32. By moving the lever 33, the slider 34 slides inside the first fixing block 31 and the second fixing block 32, achieving the effect of locking and unlocking, so that the turntable 25 can be installed and removed from the device, facilitating the loading and unloading of workpieces. A drain assembly 38 is provided on the front side of the electroplating tank 1, a temperature measuring assembly 39 is provided inside the electroplating tank 1, and a controller 310 is provided on the right side of the electroplating tank 1.

[0038] Specifically, when it is necessary to load or unload workpieces, the electric telescopic rod 36 is activated, pushing the support plate 21 to slide outward, causing the turntable 25 to move out of the working area of ​​the electroplating tank 1. By pushing the lever 33 upward, the movement of the lever 33 drives the transmission rod 35 to rotate. The rotation of the transmission rod 35 pushes the slider 34 to slide inside the fixed block 31 and the fixed block 32. When the slider 34 slides into the fixed block 32, the engagement between the fixed block 31 and the fixed block 32 is released, and the turntable 25 can be separated from the bottom of the fixed block 31. The workpiece is removed along with the turntable 25, completing the unloading. When installing workpieces, the fixed block 32 of the turntable 25 is aligned with the fixed block 31, and the lever 33 is pushed downward, causing the slider 34 to slide into the fixed block 32, realizing the engagement between the fixed block 31 and the fixed block 32, thus achieving quick loading and unloading of workpieces.

[0039] Reference Figure 4 , Figure 5 and Figure 6 The anode assembly 27 includes a support rod 271, which is slidably connected to the outside of the electroplating tank 1. An anode bag 273 is fixedly connected to the outside of the support rod 271 to wrap the anode plate 272, preventing anode mud and particulate impurities from entering the plating solution and ensuring the purity of the plating layer. The anode plate 272 is slidably connected inside the anode bag 273. The stirring assembly 28 includes a rotating shaft 281, with two rotating shafts 281 fixedly connected to the bottom front and rear sides of the electroplating tank 1, respectively. A paddle 282 is fixedly connected to the top of the rotating shaft 281. Starting the rotating shaft 281 drives the paddle 282 to rotate, thereby achieving the effect of stirring the electroplating solution. The heating assembly 29 includes a protective sleeve 291, which is fixedly connected to the bottom of the electroplating tank 1. A heating tube 292 is fixedly connected inside the protective sleeve 291. The protective sleeve 291 is used to protect the heating tube 292 from corrosion by the electroplating solution and to keep the heating effect stable.

[0040] Specifically, when electroplating is required, the support rod 271 is placed on the outer groove of the electroplating tank 1, and the anode plate 272 is inserted into the anode bag 273. The microporous structure of the anode bag 273 allows metal ions to pass through while blocking anode mud and solid particles from entering the electroplating solution. After being energized, the anode plate 272 dissolves, and the metal enters the electroplating solution in the form of ions. When the stirring assembly 28 is running, the rotating shaft 281 rotates under the drive of the drive device, and the blade 282 fixed on the top of the rotating shaft 281 rotates accordingly. The rotation of the blade 282 causes the electroplating solution to flow continuously, so that the components of the electroplating solution in the electroplating tank 1 are evenly distributed. When the heating assembly 29 is working, the heating tube 292 is energized to generate heat. The heat is conducted to the electroplating solution through the protective sleeve 291. The sealing structure of the protective sleeve 291 isolates the heating tube 292 from direct contact with the electroplating solution, preventing the electroplating solution from corroding the heating tube 292.

[0041] Reference Figure 1 , Figure 2 and Figure 4The drain assembly 38 includes a drain pipe 381, which is connected to the outside of the electroplating tank 1. A valve 382 is rotatably connected to the top of the drain pipe 381. When the electroplating solution needs to be replaced or the device needs to be repaired, the drain pipe 381 is opened by rotating the valve 382, ​​allowing the liquid in the electroplating tank 1 to flow out through the drain pipe 381. The temperature measuring assembly 39 includes two thermometers 391, which are fixedly connected to the left and right sides of the inside of the electroplating tank 1, respectively. The detection end of the thermometer 391 is fixedly connected to a protective device. The second sleeve 392 is used to protect the detection end of the thermometer 391 from corrosion by the electroplating solution, so as to keep the temperature measurement effect stable. The controller 310 is fixedly connected to the right side of the electroplating tank 1. The controller 310 is electrically connected to the electric telescopic rod 22, the motor 24, the anode plate 272, the rotating shaft 281, the heating tube 292, the electric telescopic rod 36, and the thermometer 391. In this way, the working status of different parts in the device can be controlled by the controller 310, making the operation of the device more convenient.

[0042] Specifically, when it is necessary to replace the electroplating solution or perform maintenance on the device, the valve 382 is rotated from the closed state to the open state, and the liquid in the electroplating tank 1 is discharged from the drain pipe 381. The valve 382 adopts a sealing structure design, which can effectively prevent liquid leakage when closed. After the liquid is drained, the valve 382 is rotated in the opposite direction to the closed position to cut off the drain channel. The temperature measuring component 39 monitors the temperature of the electroplating solution in real time and displays the temperature on the display screen of the controller 310. The controller 310 can simultaneously control the lifting and lowering of the electric telescopic rod 22, the speed adjustment of the motor 24, the start and stop of the rotating shaft 281, the extension and retraction of the electric telescopic rod 36, and the energization status of the anode plate 272, making the operation of the device more convenient.

[0043] Working principle: First, electroplating solution is injected into the electroplating tank 1. The workpiece to be coated is hung on the hook 26 at the bottom of the turntable 25. The turntable 25 is fixedly installed by the engagement of the first fixing block 31 and the second fixing block 32. The first electric telescopic rod 22 extends downward, driving the fixing box 23 and the turntable 25 to descend as a whole. After the motor 24 starts, it drives the first fixing block 31 to rotate through the output shaft, which in turn drives the second fixing block 32 to rotate synchronously with the turntable 25. The rotation of the turntable 25 causes the suspended workpiece to move continuously in the electroplating solution. The anode components 27 on the front and rear sides of the electroplating tank 1 generate an electric field when energized. Under the action of the electric field, the metal ions in the plating solution gather on the surface of the workpiece. After the electroplating is completed, the first electric telescopic rod 22 rises and drives the turntable 25 to detach from the electroplating solution, achieving a more uniform coating effect on the workpiece.

[0044] Furthermore, when it is necessary to load or unload workpieces, the electric telescopic rod 36 is activated to push the support plate 21 to slide outward, so that the turntable 25 is moved out of the working area of ​​the electroplating tank 1. By pushing the lever 33 upward, the movement of the lever 33 drives the transmission rod 35 to rotate. The rotation of the transmission rod 35 pushes the slider 34 to slide inside the fixed block 31 and the fixed block 32. When the slider 34 slides into the fixed block 32, the fixed block 31 and the fixed block 32 are released from engagement, the turntable 25 is separated from the fixed block 31, and the workpiece is removed together with the turntable 25. When installing the turntable, the fixed block 32 of the turntable 25 is aligned with the fixed block 31, and the lever 33 is pushed downward, so that the slider 34 slides into the fixed block 32, realizing the engagement of the fixed block 31 and the fixed block 32, thus achieving quick loading and unloading of workpieces.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
