Detailed Implementation
[0030] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.

A rotating shaft 3 is rotatably connected to the bottom of the inner cavity of the concave plate 2 via a bearing. A turntable 4 is fixedly connected to the top of the rotating shaft 3. The diameters of the turntable 4 and the pressure plate 7 are smaller than the diameter of the tappet. A drive assembly 5 is provided at the bottom of the inner cavity of the base frame 1. An electric cylinder 6 is fixedly installed on the top of the concave plate 2.

The inner surface of the guide frame 11 slides... The guide plate 12 is connected to the guide plate 12. The left end of the guide plate 12 is fixedly connected to the arc plate 9. A limit component 13 is provided on the right side of the front of the guide plate 12. The drive component 5 includes a rotary motor 501. The bottom of the rotary motor 501 is fixedly connected to the bottom frame 1. A main helical gear 502 is fixedly connected to the output end of the rotary motor 501. The bottom of the rotating shaft 3 passes through the concave plate 2 and is fixedly connected to a driven helical gear 503. The main helical gear 502 and the driven helical gear 503 mesh. There are four mounting holes at the four corners of the bottom of the inner cavity of the bottom frame 1. A rotating handle is fixedly connected to the right end of the screw 8. The outer surface of the rotating handle is provided with anti-slip texture. Rubber pads 15 are fixedly connected to the opposite ends of the pressure plate 7 and the turntable 4. The rubber pads 15 are circular.
[0033] In this embodiment: By setting a base frame 1, a concave plate 2, a rotating shaft 3, a turntable 4, a drive assembly 5, an electric cylinder 6, and a pressure plate 7, this utility model can easily hold and limit the tappet. At the same time, the drive assembly 5 can facilitate the rotation of the tappet. By setting a screw 8, an arc plate 9, a polishing cloth 10, a guide frame 11, a guide plate 12, and a limiting assembly 13, it can easily contact and polish tappets of different diameters. By setting the above structure, it is convenient to quickly polish the tappet, thereby meeting the needs of customers. At the same time, it effectively reduces the labor intensity of workers and improves the polishing efficiency of the tappet.
[0034] Example 2:
[0035] Reference Figure 1 , Figure 2 and Figure 4The limiting component 13 includes a stud 131. The front of the stud 131 passes through the guide frame 11 and is threadedly connected to a limiting nut 132. The outer surface of the limiting nut 132 is tightly fitted to the connection of the guide frame 11. The front of the guide frame 11 is provided with a moving groove 14 that cooperates with the stud 131. The outer surface of the stud 131 is fixedly connected to the connection of the guide plate 12.
[0036] In this embodiment: By setting studs 131 and limiting nuts 132, the present invention can conveniently limit the connection between the guide plate 12 and the guide frame 11.
[0037] The implementation principle of this utility model is as follows: When in use, the operator fixes the device in the designated position by using the mounting holes and screws. Then, the device is electrically connected to the mains power. When it is necessary to polish the push column, the operator moves push columns of different sizes so that the bottom of the push column is placed at the center of the rubber pad 15 on the top of the turntable 4. Then, the operator starts the external controller of the electric cylinder 6, so that the extension end of the electric cylinder 6 drives the pressure plate 7 to move downward, so that the pressure plate 7 drives the rubber pad 15 to move downward and press and contact the connection of the push column, thereby completing the pressing and positioning of the push column.
[0038] Next, the operator starts the external controller of the rotary motor 501, causing the output of the rotary motor 501 to drive the main helical gear 502 to rotate. The main helical gear 502 drives the driven helical gear 503 to rotate, which in turn drives the rotating shaft 3 to rotate. The rotating shaft 3 drives the turntable 4, rubber pad 15, and pressure plate 7 to rotate, thus enabling the pressure plate 7, rubber pad 15, and turntable 4 to work together to drive the tappet to rotate. Then, the operator rotates the handle, causing the screw 8 to rotate on the inner surface of the concave plate 2. This causes the screw 8 to move the arc plate 9 to the left, and the arc plate 9 causes the guide plate 12 to slide to the left on the inner surface of the guide frame 11. The polishing cloth 10 is moved to the left to adapt to and contact with push rods of different diameters, allowing the polishing cloth 10 to quickly polish the rotating push rods. At the same time, the operator rotates the limiting nut 132, causing the limiting nut 132 to rotate and move on the outer surface of the push rod 131 and fit tightly against the connection of the guide frame 11. This limits the connection between the guide frame 11 and the guide plate 12, preventing the arc plate 9 from moving the polishing cloth 10 and affecting the polishing effect. This device is simple to operate and facilitates rapid polishing, thus meeting the needs of customers. At the same time, it effectively reduces the labor intensity of operators and improves the polishing efficiency of the push rods.
[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
