[0032] The processing box 21 and the linear sliding base 22 are placed in the assembly box 13, which has a sealed space, and the linear sliding base 22 slides back and forth.
[0033] In this embodiment: A push base 24 for sliding back and forth is placed horizontally at the top center of the linear sliding base 22. A linear push block 25 is clamped on the top surface of the push base 24. A drive motor 26 is provided on the side of the linear push block 25. An ultrasonic detector 27 is provided on the surface of the linear push block 25.
[0034] In this embodiment: the detection end of the ultrasonic detector 27 is clamped to the middle of the corresponding car steering wheel 392, and a polishing mechanism 3 is also placed on the top side of the processing box 21;
[0035] The polishing mechanism 3 includes a clamping push motor 31 placed on the top side of the processing box 21. A motor support 32 is also installed on the middle side of the clamping push motor 31. A polishing bearing plate 33 for polishing is provided at the top center of the motor support 32. Two polishing motors 34 are symmetrically arranged on the top surface of the polishing bearing plate 33.
[0036] The fixture push motor 31 is used to control the position of the fixture inside the processing box 21, and one end of the polishing motor 34 is used to clamp it.
[0037] In this embodiment: the top of the polishing motor 34 is fitted with a sanding belt drive roller shaft 35, the surface of the sanding belt drive roller shaft 35 is fitted with a transmission sanding belt 36 for transmission, the top center of the transmission sanding belt 36 is fitted with a connecting protrusion 37 for support, the end of the connecting protrusion 37 is horizontally fitted with a pneumatic cylinder 38, the other end of the pneumatic cylinder 38 is fitted with a transmission base 39, the two ends of the transmission base 39 are respectively symmetrically fitted with belt roller shafts 391, and the belt roller shafts 391 are connected to the surface of the transmission sanding belt 36 for transmission.
[0038] The transmission abrasive belt 36 is driven by the polishing motor 34, which is energized to drive the transmission abrasive belt 36 to rotate.
[0039] In this embodiment: a steering wheel 392 for polishing is clamped in the gap between adjacent transmission abrasive belts 36, the edge of the steering wheel 392 is clamped between the corresponding two transmission abrasive belts 36, a U-shaped clamp 3921 is clamped on the surface of the steering wheel 392, and a transmission roller shaft 3922 is hinged to the bottom of the U-shaped clamp 3921.
[0040] The U-shaped clamp 3921 is used to place and fix the steering wheel 392 in a clamping structure, which facilitates subsequent polishing.
[0041] In this embodiment: the bottom of the transmission roller shaft 3922 is provided with an arc-shaped bracket 394, the middle part of the arc-shaped bracket 394 is provided with a drive roller shaft 395, and the middle part of the drive roller shaft 395 is clamped with a damper 396.
[0042] The axial structural changes of the arc-shaped bracket 394 and the drive roller shaft 395.
[0043] In this embodiment: the side wall of the assembly box 13 is provided with a control box 393, and the surface of the arc-shaped processing cover 14 is covered with a protective cover.
[0044] The control box 393 is fixed in place.
[0045] In practical use, the first step is to lift the protective cover;
[0046] After opening, a material is directly exposed inside the steering wheel insertion cavity 15 for better placement. Then, the user activates the drive motor 26, which slides and moves back and forth, causing the surface of the polishing support plate 33 to move and reposition. It stops when it reaches the appropriate position. The user then uses the ultrasonic detector 27 to activate the back and forth movement, further controlling the connecting protrusions 37 for transmission. Following the corresponding clamps, the motor 31 moves back and forth, changing the structure of the polishing support plate 33 to achieve the position of the polishing motor 34, thus achieving the desired displacement. When the photoelectric motor 34 is energized, it drives the drive roller shaft 395 to rotate, which in turn drives the transmission abrasive belt 36 to rotate. This causes the edge of the steering wheel 392 to come into contact and clamp, achieving closure. The clamping is achieved through the axial support of the belt roller shaft 391. At this time, the user adjusts the connection of the drive roller shaft 395 to achieve rotation. As the arc support 394 rotates, it directly drives the rotation and turning process. During the turning process, the structure of the transmission roller shaft 3922 is further changed to achieve rotation. After clamping by the U-shaped clamp 3921, the surface of the steering wheel 392 is clamped to achieve surface polishing.
[0047] Step 2: Remove the polished steering wheel 392;
[0048] At this point, the user only needs to loosen the slot in the middle of the U-shaped clamp 3921 to open it, and then take out the steering wheel 392. It can be taken out by adjusting the rotation of the drive roller 395.
[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
