Description

Technical Field

[0001] This utility model relates to the field of automotive pulley technology, specifically to the electroplating structure of automotive pulleys. Background Technology

[0002] Pulleys, belonging to the category of disc-hub parts, are generally manufactured using casting and forging processes. They are primarily used for long-distance power transmission, such as in small diesel engines, mining machinery, machining equipment, textile machinery, packaging machinery, agricultural machinery, air compressors, speed reducers, generators, cotton gins, and so on.

[0003] Currently, during the manufacturing process of automotive pulleys, an additional layer of wear-resistant metal is often electroplated onto the surface to alter the surface properties of the substrate, enhance the corrosion resistance, hardness, wear resistance, smoothness, and heat resistance of the substrate metal, and improve the aesthetics of the surface.

[0004] China has authorized a utility model publication (announcement) number: CN205653521U, which describes an electroplating device for automotive pulleys. The device includes an electroplating tank, a support column, a motor, and an air pump. The support column is vertically fixed to the outer wall of the electroplating tank. A slide rail is provided on the upper part of the support column near the electroplating tank. The air pump is mounted on the support column on the side opposite to the slide rail. The motor is horizontally mounted at the top of the support column, with its output end located above the slide rail. A hook is provided above the electroplating tank. The hook includes a vertical column and a horizontal bar fixed to the lower end of the vertical column. The horizontal bar is a horizontally arranged cylinder. An air bladder is provided on the horizontal bar, and the air pipe of the air pump is connected to the air bladder. A slider is fixed to the hook, and the slider slides in cooperation with the slide rail. A drum is connected to the output end of the motor, and a cable is fixed to the drum. The free end of the cable is fixed to the slider.

[0005] However, if the cable of the existing automotive pulley electroplating structure breaks due to accident or poor quality, the slider may collide violently with the column, which may damage the slider. Utility Model Content

[0006] The purpose of this invention is to provide an electroplating structure for automotive pulleys to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model's automotive pulley electroplating structure uses a drive motor to rotate a lead screw, thereby moving a sliding block. Unlike existing lead screw drives, this design incorporates a telescopic rod at the bottom of the interlocking block to prevent transmission accidents caused by wear on the lead screw's threads. If wear causes an accident involving the slider, interlocking block, and sliding block assembly, the telescopic rod provides support. Furthermore, a buffer spring on the telescopic rod's surface provides cushioning, ensuring safer and more convenient lifting and lowering of the slider, interlocking block, and sliding block assembly.

[0023] Please see Figure 1-3 This utility model provides a technical solution:

[0024] The electroplating structure for an automotive pulley includes an electroplating tank 1 and a support column 2. The support column 2 is located on the back of the electroplating tank 1, and a sliding inner cavity 9 is formed on the front of the support column. The top and bottom centers of the sliding inner cavity 9 are respectively connected to two different ends of a lead screw 10. A sliding block 11 is sleeved on the surface of the lead screw 10, and fitting blocks 12 are provided on both sides of the sliding block 11. Sliding guide rails 16 are provided on the top and bottom sides of the sliding inner cavity 9, and fitting inner cavities 17 are formed on the inner sides of the sliding guide rails 16. The fitting inner cavities 17 are slidably connected to the sliding inner cavities. The two ends of the interlocking block 12 and the sliding block 11 are provided with clamping blocks 13. The back of the clamping blocks 13 is in contact with the side of the sliding guide rail 16. The front of the combination of the sliding block 11 and the interlocking block 12 is provided with a slider 4. The front of the slider 4 is provided with a column 5 in the longitudinal direction. The surface of the column 5 is provided with a crossbar 6. The surface of the crossbar 6 is provided with an airbag 7. Specifically, it should be noted that in this utility model, the car pulley is placed at the airbag 7. The specific usage method is the same as that of the prior art, and will not be described in detail here.

[0025] Furthermore, an air pump 3 is fixedly connected to the top of the back of the support column 2. An air pipe 8 is provided at the top air outlet of the air pump 3. The other end of the air pipe 8 is connected to the crossbar 6. The air pipe 8 is connected to the airbag 7.

[0026] Furthermore, a telescopic rod 14 is provided at the bottom center of the fitting cavity 17, and the top telescopic end of the telescopic rod 14 is connected to the bottom of the fitting block 12.

[0027] Furthermore, a buffer spring 15 is sleeved on the surface of the telescopic rod 14. The bottom of the buffer spring 15 is connected to the bottom of the fitting inner cavity 17, and the top of the buffer spring 15 is connected to the bottom of the fitting block 12.

[0028] Furthermore, the sliding guide rail 16 has longitudinal grooves on both sides, and the back of the clamping block 13 is provided with a sliding rod. The sliding rod is fitted and slidably connected to the groove. During the movement of the combination of slider 4, fitting block 12 and sliding block 11, the sliding rod at the clamping block 13 will move along the groove, making the movement between the combination more stable.

[0029] Furthermore, a drive motor 18 is fixedly connected to the top center of the support column 2, and the bottom output end of the drive motor 18 is connected to the top of the lead screw 10.

[0030] Working principle: The electroplating structure of the automotive pulley of this utility model drives the lead screw 10 to rotate through the rotation of the drive motor 18. Since the sliding block 11 is sleeved on the lead screw 10, and the two sides of the sliding block 11 are fitted and slidably connected in the fitting cavity 17, the sliding block 11 can move up and down. Unlike the lead screw 10 transmission in the prior art, in order to prevent the transmission accident caused by the wear of the threads on the surface of the lead screw 10, a telescopic rod 14 is provided at the bottom of the fitting block 12. When the lead screw 10 wears and causes the combination of slider 4, fitting block 12 and sliding block 11 to fall rapidly downward, the telescopic rod 14 can provide simple support for the combination. In addition, a buffer spring 15 is provided on the surface of the telescopic rod 14. The buffer spring 15 mainly plays a buffering role, making the lifting and lowering of the combination of slider 4, fitting block 12 and sliding block 11 safer and more convenient to use.

[0031] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0032] 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.
