Description

Technical Field

[0001] This utility model relates to the field of electroplating fixture technology, specifically to an electroplating fixture for hardware parts. Background Technology

[0002] Electroplating fixtures are devices used to fix and support parts to be electroplated, playing a crucial role in the electroplating process. They ensure that parts remain stable in the electroplating solution, preventing uneven plating or damage caused by movement or deformation. The design and manufacture of electroplating fixtures must take into account factors such as the shape of the parts, plating technology requirements, electroplating processes, and equipment size.

[0003] After the parts are clamped and fixed in place using an electroplating fixture, they can be placed into the electroplating solution for electroplating. However, because the concentration of the electroplating solution changes during use, the surface coating of the parts may become uneven after they are placed in the electroplating solution, which will affect the overall quality of the electroplating. Utility Model Content

[0004] The purpose of this utility model is to provide a metal electroplating fixture to solve the problems mentioned in the background art.

[0012] This utility model provides a metal electroplating fixture, which has the following advantages:

[0013] (1) By starting the drive motor, the output shaft of the drive motor drives the drive gear to rotate. Due to the meshing of the transmission gear and the drive gear, the transmission gear drives the connecting shaft and the rotating plate to rotate, thereby causing the hardware to rotate in the electroplating solution.

[0014] (2) This utility model uses a rotating turntable to make the rotating shaft drive the convex plate to rotate. The spiral spring sheet is wound up with the rotation of the rotating shaft. After rotating a certain angle, the convex plate contacts the adjusting plate and squeezes the adjusting plate inward.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 and Figure 5 As shown, in this embodiment, a metal electroplating fixture includes a top plate 1, a connecting frame 2 fixedly connected to the top of the top plate 1, a drive motor 3 fixedly connected to the top of the connecting frame 2, a drive gear 4 fixedly sleeved on the output shaft of the drive motor 3, a transmission gear 5 meshing on the surface of the drive gear 4, a connecting shaft 6 fixedly connected to the inner wall of the transmission gear 5, a rotating plate 7 fixedly connected to the bottom end of the connecting shaft 6, a sliding rod 8 fixedly connected to the top of the rotating plate 7, a guide groove 9 opened at the bottom of the top plate 1, a hanging plate 10 fixedly connected to the top of the top plate 1, and a hole groove 11 opened in the middle of the hanging plate 10.

[0023] By starting the drive motor 3, its output shaft drives the drive gear 4 to rotate. Since the transmission gear 5 and the drive gear 4 mesh, the transmission gear 5 drives the connecting shaft 6 and the rotating plate 7 to rotate, thereby causing the hardware parts to rotate in the electroplating solution. The electroplating solution flows with the rotation of the hardware parts, thereby keeping the concentration of the electroplating solution uniform, so as to ensure that the plating layer on each side of the hardware parts is consistent, thereby improving the overall effect after electroplating. At the same time as the rotating plate 7 rotates, the slide rod 8 slides in the guide groove 9 to ensure the stability during the rotation process.

[0024] The connecting frame 2 adopts a U-shaped structure. The drive gear 4 and transmission gear 5 are located inside the connecting frame 2. The slide rod 8 and guide groove 9 are matched. There are two holes and slots 11.

[0025] The bottom of the rotating plate 7 is fixedly connected to the mounting frame 12. The inside of the mounting frame 12 is rotatably connected to the rotating shaft 13. The front of the rotating shaft 13 is fixedly connected to the turntable 14. The surface of the rotating shaft 13 is fixedly fitted with a convex rib plate 15. The surface of the rotating shaft 13 is fixedly connected with a helical spring plate 16. The left side of the mounting frame 12 is provided with a notch 17.

[0026] By rotating the turntable 14, the rotating shaft 13 drives the convex plate 15 to rotate. The spiral spring plate 16 is wound up with the rotation of the rotating shaft 13. After rotating a certain angle, the convex plate 15 contacts the adjusting plate 23 and presses the adjusting plate 23 inward. The connecting spring 26 is compressed and contracted, thereby causing the adjusting plate 23 and the connecting rod 18 to rotate, so as to improve the convenience of opening and closing the electroplating fixture.

[0027] The turntable 14 is located outside the mounting frame 12, the convex rib plate 15 and the notch 17 are adapted to each other, and the end of the helical spring plate 16 away from the rotating shaft 13 is fixedly connected to the mounting frame 12.

[0028] A connecting rod 18 is fixedly connected to the bottom end of the rotating plate 7. A first clamping plate 19 is fixedly connected to the bottom end of the connecting rod 18. A guide plate 20 is fixedly connected to the side of the first clamping plate 19 near the mounting frame 12. A first gasket 21 is fixedly connected to the side of the first clamping plate 19 near the guide plate 20.

[0029] A connecting block 22 is fixedly connected to the side of the connecting rod 18 near the guide plate 20. An adjusting plate 23 is rotatably connected to the surface of the connecting block 22. A second clamping plate 24 is fixedly connected to the bottom end of the adjusting plate 23. A second gasket 25 is fixedly connected to the side of the second clamping plate 24 near the first clamping plate 19.

[0030] By providing a first gasket 21 and a second gasket 25 on one side of the first clamping plate 19 and the second clamping plate 24, and by providing friction surfaces on the first gasket 21 and the second gasket 25, the stability of the hardware after fixing is improved.

[0031] A connecting spring 26 is fixedly connected to the side of the adjusting plate 23 near the connecting rod 18. A connecting bolt 27 is provided inside the adjusting plate 23, and a nut 28 is threaded onto the surface of the connecting bolt 27.

[0032] By using connecting bolts 27 and nuts 28 to connect the connecting rod 18 and the adjusting plate 23, when it is necessary to disassemble and replace the electroplating fixture components, the nut 28 can be separated from the connecting bolts 27 using a wrench, and the worn parts can be replaced.

[0033] This utility model provides a metal electroplating fixture, the specific working principle of which is as follows:

[0034] In use, the electroplating fixture is suspended on the hanger via the hanging plate 10. Rotating the turntable 14 causes the rotating shaft 13 to drive the convex plate 15 to rotate. The spiral spring 16 winds up as the shaft 13 rotates. After rotating a certain angle, the convex plate 15 contacts the adjusting plate 23 and presses it inward, compressing the connecting spring 26. This causes the adjusting plate 23 and connecting rod 18 to rotate, opening the electroplating fixture. The hardware is then placed between the first clamping plate 19 and the second clamping plate 24. After releasing the handle, the spiral spring 16... 16 springs back, causing the convex rib plate 15 to rotate and separate from the adjusting plate 23. Under the elastic force of the connecting spring 26, the second clamping plate 24 moves closer to the first clamping plate 19, thereby fixing the position of the hardware. After the hardware is placed into the electroplating solution, the drive motor 3 is started, and its output shaft drives the drive gear 4 to rotate. Since the transmission gear 5 and the drive gear 4 mesh, the transmission gear 5 drives the connecting shaft 6 and the rotating plate 7 to rotate, thereby causing the hardware to rotate in the electroplating solution to ensure the uniformity of the plating layer on each surface of the hardware.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
