Description

Technical Field

[0001] This utility model belongs to the technical field of hardware processing equipment, and in particular relates to a quick-change rotary chuck for small hardware electroplating fixtures. Background Technology

[0002] In the field of small metal parts processing for leather bags, electroplating is an important processing method to improve the appearance quality and corrosion resistance of metal parts. With the development of the leather bag industry, higher requirements have been put forward for the electroplating quality and production efficiency of small metal parts.

[0003] Currently, in the electroplating process, the commonly used electroplating racks are usually hung with hooks and a rotating disk, and then fixed with bolts. This method allows the rotating disk to drive the electroplating rack to rotate during the electroplating process, so that small metal parts can be subjected to current more evenly in the electroplating solution, increasing the uniformity of electroplating and improving the electroplating quality.

[0004] Before and after electroplating, workers need to manually remove and install the bolts of the fixing fixture. Since the removal and installation of bolts requires special tools, and in some cases, due to space constraints, rust, or loose bolts, the removal and installation process may be very difficult. This results in a lot of time being spent each time the fixture is replaced, which seriously affects the continuity and efficiency of electroplating production.

[0005] To address these issues, we provide a quick-change rotary chuck for small metal plating fixtures. Utility Model Content

[0006] The purpose of this utility model is to provide a quick-change rotary chuck for small metal electroplating racks. Through the cooperation of the snap-fit ​​component and the rotating component, it solves the technical problem that the electroplating racks in the prior art need to be manually disassembled and assembled, which is inconvenient and inefficient, and ultimately affects the electroplating production efficiency.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0030] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Example 1

[0032] Please see Figures 1-6This utility model is a quick-change rotary chuck for a small metal electroplating fixture, including an electroplating shell 1, a bracket 2 on the top of the electroplating shell 1, a turntable 3 on the top of the bracket 2, and a snap-fit ​​component on one side of the turntable 3.

[0033] The snap-fit ​​assembly includes a snap-fit ​​plate 4 mounted on the top of the turntable 3, a rotating piece 5 snapped onto the snap-fit ​​plate 4, and the rotating piece 5 mounted on the rotating shaft 16 at the output end of the servo motor 15. The servo motor 15 drives the rotating piece 5 to rotate. The snap-fit ​​assembly also includes a disc 6 slidably connected inside the turntable 3, and a snap-fit ​​block 7 mounted on the top of the disc 6.

[0034] A rotating assembly is provided on one side of the electroplating shell 1. The rotating assembly includes a drive motor 8 mounted on one side of the electroplating shell 1, a horizontal plate 9 mounted on the output end of the drive motor 8, and a slot 10 formed inside the horizontal plate 9. The drive motor 8 is used to drive the horizontal plate 9 to rotate, thereby adjusting the position of the two sets of hangers 2. This allows the electroplated hardware parts to be moved out of the electroplating shell 1, and the unplated parts to be transferred to the top of the electroplating shell 1, thus effectively improving the electroplating efficiency of the hardware parts.

[0035] Example 2

[0036] Please see Figures 1-6 Based on Embodiment 1, a driving assembly is provided on the top of the electroplating shell 1. The driving assembly includes a support column 11 installed on one side of the electroplating shell 1, a first hydraulic rod 12 installed on the top of the support column 11, and a second hydraulic rod 13 located on one side of the first hydraulic rod 12. The first hydraulic rod 12 is used to drive the hanger 2 to move left and right, and the second hydraulic rod 13 can adjust the height of the hanger 2, making it convenient to sink the hanger 2 into the electroplating shell 1 for electroplating of hardware parts.

[0037] The drive assembly also includes a movable frame 14 mounted on the output end of the second hydraulic rod 13, and a servo motor 15 mounted inside the movable frame 14. The output end of the servo motor 15 is fixedly connected to a rotating shaft 16, and the other end of the rotating shaft 16 is fixedly connected to a rotating plate 5. A bracket 17 is fixedly connected to the surface of the second hydraulic rod 13, and the output end of the first hydraulic rod 12 is fixedly connected to the bracket 17.

[0038] Furthermore, the snap-fit ​​assembly also includes a return spring 18 installed at the bottom of the disc 6. The return spring 18 can provide elastic support for the disc 6, allowing the two sets of snap-fit ​​blocks 7 to move out of the top of the turntable 3. There are two moving rods 19 installed at the bottom of the disc 6. When the two moving rods 19 rotate to align with the slots 10 of the horizontal plate 9, the two sets of moving rods 19 can move into the slots 10 of the horizontal plate 9.

[0039] Furthermore, a limit block 20 is installed at the bottom of the moving rod 19, which can prevent the two sets of moving rods 19 from moving upward.

[0040] A DC rectifier 21 is installed on the electroplating shell 1, and the electroplating shell 1 contains an electrolyte (a solution containing the metal ions to be plated). Both the positive and negative terminals of the DC rectifier 21 are equipped with conductive rods, with the anode located on the positive conductive rod. When the hanger 2 is submerged in the electroplating shell 1 and positioned for electroplating, the hanger 2 abuts against the conductive rod of the negative terminal. The metal parts to be electroplated are hung on the hooks on the side of the hanger 2.

[0041] The current required for electrolysis is provided by DC rectifier 21. The anode is made of the metal to be plated. During electroplating, the anode metal is oxidized, releases electrons and dissolves into metal ions. The cathode (hardware) gains electrons, and the metal ions in the solution gain electrons on the cathode surface and are deposited into a plating layer.

[0042] Furthermore, the width of the limiting block 20 is greater than the width of the slot 10, the bottom of the moving rod 19 extends through to the outside of the turntable 3, and one end of the reset spring 18 is fixedly connected to the disc 6.

[0043] The working principle of this utility model is as follows: the hardware parts to be electroplated are hung on the hook on the side of the hanging frame 2, the second hydraulic rod 13 is activated, the second hydraulic rod 13 drives the moving frame 14 and the hanging frame 2 to move downward until the hanging frame 2 reaches the electroplating position and abuts against the conductive rod of the negative terminal of the DC rectifier 21.

[0044] Start the DC rectifier 21 to perform electroplating until the metal parts on the surface of the bracket 2 are electroplated. Then start the second hydraulic rod 13. The second hydraulic rod 13 drives the moving frame 14 and the servo motor 15 to move upward. The servo motor 15, together with the rotating plate 5, drives the disc 6 to move upward. The disc 6 drives the bracket 2 to move, so that the moving rod 19 is aligned with the slot 10 of the horizontal plate 9.

[0045] Then, the first hydraulic rod 12 is activated, which pushes the disc 6 and the bracket 2 to the left, as shown. Figure 4 As shown, insert the two sets of moving rods 19 into the slots 10 of the horizontal plate 9, and then activate the second hydraulic rod 13 again. The second hydraulic rod 13 drives the rotating plate 5 and the turntable 3 to move. At this time, the horizontal plate 9 will contact the limit block 20, preventing the moving rods 19 from moving upward. At the same time, the moving rods 19 can drive the disc 6 and the locking block 7 to move and squeeze the return spring 18. After the locking block 7 moves back into the turntable 3, the limit on the rotating plate 5 can be released. At this time, the servo motor 15 is activated, driving the rotating shaft 16 and the rotating plate 5 to rotate clockwise, so that the rotating plate 5 is disengaged from the locking plate 4, and the second hydraulic rod 13 drives the rotating plate 5 to move upward and disengage from the turntable 3, thus completing the quick disassembly of the hanger 2.

[0046] After the bracket 2 is removed, it will hang on the surface of the horizontal plate 9. At this time, the drive motor 8 can be started to adjust the position of the two brackets 2. The metal parts that have been electroplated are transferred out of the electroplating shell 1 by rotation, and the unplated metal parts are transferred to the top of the electroplating shell 1. The second hydraulic rod 13 is started again to drive the rotating plate 5 to contact the turntable 3. Then the servo motor 15 is started again, and the servo motor 15 drives the rotating plate 5 to rotate counterclockwise, so that the rotating plate 5 is inserted into the snap-fit ​​plate 4, thus completing the quick installation and effectively improving the electroplating efficiency of the metal parts.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
