Description

Technical Field

[0001] This utility model relates to the field of nickel plating process, and more particularly to a workpiece suspension and rotation mechanism for electroless nickel plating process. Background Technology

[0002] When depositing highly corrosion-resistant and wear-resistant nickel-phosphorus alloys on complex workpiece surfaces using electroless nickel plating processes, challenges arise from mass transfer limitations, bubble retention, and uneven plating coverage in deep holes. Static suspension is insufficient to overcome these problems, easily leading to uneven thickness, incomplete plating, and pinhole defects. Dedicated workpiece suspension and rotation mechanisms have been developed to address these issues, becoming core equipment for ensuring coating quality. Through controllable rotational motion, they force solution renewal on the workpiece surface, accelerating reactant transfer and byproduct removal, significantly improving coating uniformity, density, and deep hole coverage.

[0003] Existing workpiece suspension and rotation mechanisms used in electroless nickel processing typically require the workpiece to be hung on hooks on the suspension mechanism so that the workpiece can move with the suspension mechanism in the solution. However, in actual use, since most suspension mechanisms are welded together, when a long workpiece is hung on the suspension mechanism, the bottom of the workpiece will contact the upper hook structure, thus affecting the stability of the workpiece suspension. Therefore, a workpiece suspension and rotation mechanism for electroless nickel processing is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a workpiece suspension and rotation mechanism for electroless nickel processing, aiming to improve the problem that the spacing of the suspension mechanism in the prior art is not easy to adjust, which affects the suspension stability of long workpieces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A workpiece suspension and rotation mechanism for electroless nickel processing includes a vertical rod, a rack fixedly connected to the front inner wall of the vertical rod, a limit rod fixedly connected to the middle of the vertical rod, a slider slidably connected to the outer periphery of the limit rod, a rotating shaft fixedly connected to the outer periphery of the slider, a gear rotatably connected to the outer periphery of the rotating shaft, the gear meshing with the rack, a locking assembly installed on the front side of the slider, a sleeve fixedly connected to the end of the slider away from the gear, a crossbar slidably connected to the middle of the sleeve, a hook fixedly connected to the outer side of the crossbar, and a fixing assembly installed between the sleeve and the crossbar.

A blocking block is fixedly connected to the outer periphery of the pull rod. A compression spring is sleeved on the outer periphery of the pull rod. A pull block is fixedly connected to one end of the pull rod, and the other end of the pull rod is slidably connected to the middle of the gear.

[0010] As a further description of the above technical solution:

[0011] A mounting base is slidably connected to the top of the upright, a speed reducer is fixedly connected to the top of the mounting base, a servo motor is fixedly connected to the top of the speed reducer, and the output end of the speed reducer is connected to the servo motor. A round rod is fixedly connected to the middle of the upright, a movable plate is slidably connected to the outer circumference of the round rod, a locking block is fixedly connected to the outer side of the movable plate, the other end of the locking block passes through the upright and is slidably connected to the middle of the mounting base, a push rod is fixedly connected to the outer side of the movable plate, and a compression spring is sleeved on the outer circumference of the round rod.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the pull rod is first pulled out from the middle of the gear so that the gear rotates when the slider is moved.

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.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a workpiece suspension and rotation mechanism for electroless nickel processing, comprising a vertical rod 1, a rack 10 fixedly connected to the front inner wall of the vertical rod 1, a limiting rod 3 fixedly connected to the middle of the vertical rod 1, a slider 4 slidably connected to the outer periphery of the limiting rod 3, a limiting hole 15 formed in the middle of the slider 4, the limiting rod 3 located in the middle of the limiting hole 15, a rotating shaft 16 fixedly connected to the outer periphery of the slider 4, and a gear 11 rotatably connected to the outer periphery of the rotating shaft 16, the gear 11 meshing with the rack 10. A locking assembly is installed on the front side of the slider 4. The locking assembly includes a connecting block 21, which is fixedly connected to the front side of the slider 4. A pull rod 20 is slidably connected to the middle of the connecting block 21. A stop block 18 is fixedly connected to the outer periphery of the pull rod 20. A compression spring 19 is sleeved on the outer periphery of the pull rod 20. A pull block 22 is fixedly connected to one end of the pull rod 20. The other end of the pull rod 20 is slidably connected to the middle of the gear 11. A locking hole 17 is opened in the middle of the gear 11. The pull rod 20 is slidably connected to the middle of the locking hole 17. First, according to the required length of the workpiece to be processed, pull the pull block 22 to drive the pull rod 20 to slide out of the locking hole 17 so that the gear 11 can rotate, thereby moving the slider 4 to slide on the outer periphery of the limiting rod 3, and thus adjusting the spacing of multiple sliders 4. At the same time, when the pull rod 20 is pulled, it will drive the blocking block 18 to squeeze the compression spring 19. After the pull block 22 is released, the compression spring 19 pushes the pull rod 20 to insert into the locking hole 17, thereby locking the gear 11, so that the spacing of the sliders 4 can be positioned under the action of the gear 11 and the rack 10.

[0034] Reference Figure 4 A sleeve block 5 is fixedly connected to the end of the slider 4 away from the gear 11. A crossbar 2 is slidably connected to the middle of the sleeve block 5. A hook 6 is fixedly connected to the outer side of the crossbar 2. A fixing assembly is installed between the sleeve block 5 and the crossbar 2. The fixing assembly includes a bolt 12, which is slidably connected to the middle of the sleeve block 5 and the crossbar 2. A nut 23 is threaded onto the outer circumference of the bolt 12. A sliding hole 14 is opened in the middle of both the sleeve block 5 and the crossbar 2, and the bolt 12 is slidably connected to the middle of the sliding hole 14. After the spacing of the slider 4 is adjusted, the crossbar 2 is inserted into the sleeve block 5 at the end of the slider 4, and the crossbar 2 and the slider 4 can be connected by the bolt 12 and the nut 23. Then, the spacing of the hook 6 can be adjusted according to the length of the workpiece, thereby improving the applicability of the suspension mechanism to different workpieces, avoiding collisions, and improving stability and nickel coating effect.

[0035] Reference Figure 5 A mounting base 7 is slidably connected to the top of the upright 1. A reducer 8 is fixedly connected to the top of the mounting base 7. A servo motor 9 is fixedly connected to the top of the reducer 8. The output end of the reducer 8 and the servo motor 9 are connected. A round rod 24 is fixedly connected to the middle of the upright 1. A movable plate 27 is slidably connected to the outer periphery of the round rod 24. A locking block 26 is fixedly connected to the outer side of the movable plate 27. The other end of the locking block 26 passes through the upright 1 and is slidably connected to the middle of the mounting base 7. A push rod 28 is fixedly connected to the outer side of the movable plate 27. A compression spring 25 is sleeved on the outer periphery of the round rod 24. A through hole 13 is opened in the middle of the upright 1. The locking block 26 is slidably connected to the middle of the through hole 13. A rubber sleeve 29 is sleeved on the outer periphery of the push rod 28. By squeezing the push rod 28, the dynamic movable plate 27 slides on the outer periphery of the round rod 24 and squeezes the compression spring 25. At the same time, the movable plate 27 will drive the locking block 26 to retract from the middle of the mounting base 7 into the upright rod 1, thereby quickly separating the suspension mechanism from the servo motor 9. After releasing the locking block 26, the movable plate 27 can drive the locking block 26 to slide out of the through hole 13 and insert into the mounting base 7 under the push of the compression spring 25, so as to improve the efficiency of maintenance and replacement of the suspension mechanism, thereby ensuring work efficiency. In addition, the rubber sleeve 29 can avoid the pain caused by the operator's fingers squeezing.

[0036] Working principle: First, pull rod 20 is pulled out from the middle of gear 11. At the same time, when pull rod 20 is pulled, it will drive the stop block 18 to cooperate with the connecting block 21 to squeeze the compression spring 19, so that gear 11 can rotate when moving slider 4. After moving multiple sliders 4 to the appropriate position, release pull rod 20 and insert it into gear 11, so that gear 11 cannot rotate and thus fix slider 4. Then, bolt 12 and nut 23 are used to connect crossbar 2 and slider 4, so that the suspension mechanism can adjust the spacing of upper and lower hooks 6 according to the length of the workpiece.

[0037] By squeezing the push rod 28, the movable plate 27 is pushed to move around the outer periphery of the round rod 24, so that the movable plate 27 can drive the locking block 26 from the middle of the mounting base 7 into the upright rod 1, thereby quickly separating the suspension mechanism from the drive device. At the same time, after releasing the push rod 28, the locking block 26 can be inserted into the mounting base 7 for fixation under the push of the compression spring 25, thereby improving the efficiency of maintenance and replacement.

[0038] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
