Description

Technical Field

[0001] The utility model relates to the technical field of bicycle parts processing, in particular to a pre-soaking device for electroplating bicycle pistons. Background Technique

[0002] In the process of bicycle production and processing, a large number of parts are required. In order to achieve the effect of rust prevention and extended service life, some parts are usually electroplated. Before electroplating, they need to be pickled and soaked to remove surface stains and oxide layers, so as to make the adhesion effect better during electroplating.

[0003] When electroplating parts, a hanging rack is usually set at the top of the soaking tank, and the workpiece is hung inside the soaking tank for processing. However, in actual use, for some medium-sized parts, the soaking tank is also relatively large during soaking, which makes it very inconvenient to pick up and place, and the operator is very likely to come into contact with the acidic liquid in the soaking tank. Therefore, a pre-soaking device for electroplating bicycle pistons is provided to solve the above problems. Summary of the Invention

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: A pre-soaking device for electroplating bicycle pistons includes a pickling tank and a hanging mechanism arranged on the top of the pickling tank. Lifting frames are arranged on both sides of the pickling tank, and the lifting frames are used to drive the hanging mechanism to move up and down;

[0010] Preferably, a support frame is arranged on the top of the pickling tank, and a lifting hydraulic cylinder is fixedly installed on the top of the support frame. The lifting hydraulic cylinder is used to drive the lifting frame to move up and down.

[0011] Preferably, the output end of the lifting hydraulic cylinder and both sides of the support frame penetrate through the support frame, and the output end of the lifting hydraulic cylinder is fixedly connected to the bottom of the support frame.

[0012] Preferably, a positioning slide rail is fixedly connected to the side surface of the pickling tank, and the bottom of the support frame is slidably connected to the outer surface of the positioning slide rail.

[0013] Preferably, a device seat is fixedly installed on the top of the support frame. Two sets of transmission gears are rotatably connected inside one set of device seats, and a driving motor is installed on the outer surface of the other set of device seats. The output end of the driving motor is fixedly connected to one set of rotating shafts.

[0014] Preferably, a hook is provided at the end of the suspension arm, and an anti-detachment strip is movably inserted into the inner top of the hook.

[0023] By providing a pre-soaking device for electroplating bicycle pistons in the embodiments of this application, the problem is solved that for some medium-sized fittings, when soaking, the soaking tank is relatively large, which makes it very inconvenient to take and place, and the operator is very likely to come into contact with the acidic liquid in the soaking tank.

[0024] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0025] An embodiment of the utility model discloses a pre-soaking device for electroplating bicycle pistons.

[0026] According to the attached Figures 1-3 As shown, it includes a pickling tank 1 and a hanging mechanism 2 arranged on the top of the pickling tank 1. Lifting frames 4 are arranged on both sides of the pickling tank 1, and the lifting frames 4 are used to drive the hanging mechanism 2 to move up and down;

[0027] The hanging mechanism 2 includes;

[0029] A suspension arm 22, which is fixedly installed on the outer surface of the rotating shaft 21, and the suspension arm 22 is used to support the suspended object;

[0030] A transmission gear 7 is installed at the end of the rotating shaft 21, and the two groups of transmission gears 7 are meshed with each other.

[0031] A support frame 3 is arranged on the top of the pickling tank 1, and a lifting hydraulic cylinder 5 is fixedly installed on the top of the support frame 3. The lifting hydraulic cylinder 5 is used to drive the lifting frame 4 to move up and down.

[0032] The output end of the lifting hydraulic cylinder 5 and both sides of the support frame 3 penetrate through the support frame 3, and the output end of the lifting hydraulic cylinder 5 is fixedly connected to the bottom of the support frame 3.

[0033] A positioning slide rail 8 is fixedly connected to the side of the pickling tank 1, and the bottom of the support frame 3 is slidably connected to the outer surface of the positioning slide rail 8 to prevent the support frame 3 from tilting when moving up and down.

[0034] The top of the support frame 3 is fixedly installed with a device base 6. Two sets of transmission gears 7 are rotatably connected inside one set of device bases 6. The outer surface of the other set of device bases 6 is installed with a driving motor 10. The output end of the driving motor 10 is fixedly connected to a set of rotating shafts 21. The cylinder body of the lifting hydraulic cylinder 5 penetrates the device base 6. When the output shaft of the lifting hydraulic cylinder 5 contracts, the device base 6 slides upward along the outer wall of the cylinder body of the lifting hydraulic cylinder 5.

[0035] A hook 24 is provided at the end of the suspension arm 22. An anti-detachment strip 23 is movably inserted into the inner top of the hook 24.

[0039] When the device is in use, the materials are suspended inside the pickling tank 1 through a plurality of hooks 24. At this time, the suspension arm 22 is supported by the support frame 9. When taking materials, by starting the lifting hydraulic cylinder 5, the lifting frame 4 slides upward along the positioning slide rail 8, so that the materials are lifted upward from the liquid, and then drained. Then, by starting the driving motor 10, a set of rotating shafts 21 are driven to rotate outward. At the same time, the rotating shafts 21 drive the other set of rotating shafts 21 to rotate in the opposite direction and rotate toward the other side through two sets of transmission gears 7, so that the two sets of suspension arms 22 rotate outward. At this time, by pushing the cross arm 26 inward, the anti-detachment strip 23 is moved away from the opening of the hook 24, so as to facilitate taking the suspended materials and avoid contacting the liquid inside the pickling tank 1.
