When processing control levers of different diameters, lengths, or curved surfaces, the entire processing mechanism must be replaced or the overall equipment layout adjusted, increasing production costs and reducing processing efficiency. Therefore, this invention proposes a high-precision automotive control lever surface treatment device to address these issues. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Example: like Figure 1-9 As shown, this embodiment proposes a high-precision automotive control lever surface treatment device, comprising: Base 10; Support plate 20; the support plate 20 is mounted on the base 10; support wheels 22 are mounted on the support plate 20; A drive motor 11 is mounted on a base 10; a drive wheel 12 is mounted on the drive motor 11. Displacement plate 40; two sets of driven wheels 41 are symmetrically arranged on the displacement plate 40; Adjustment component 30; the adjustment component 30 is disposed on the support plate 20; Among them, a grinding belt 60 is provided between the two sets of driven wheels 41 and a set of support wheels 22 and a set of drive wheels 12; The adjustment component 30 is also connected to the displacement plate 40, which changes the distance between the two sets of driven wheels 41 and the drive wheel 12, thereby adjusting the position of the grinding area.

[0019] In this embodiment, when processing the surface of the car control lever, the base 10 is first fixed, and then the position of the displacement plate 40 is adjusted by the adjustment component 30. Then, the polishing belt 60 is placed between the two sets of driven wheels 41, a set of support wheels 22, and a set of drive wheels 12, and the drive motor 11 is turned on. The drive motor 11 drives the drive wheels 12 to rotate, thereby causing the polishing belt 60 to move between the two sets of driven wheels 41, a set of support wheels 22, and a set of drive wheels 12. Then, the car control lever is brought into contact with the surface of the polishing belt 60 to complete the surface treatment process. With the help of the connection between the adjustment component 30 and the displacement plate 40, the displacement plate 40 can be driven to move the two sets of driven wheels 41, changing the distance between the driven wheels 41 and the drive wheel 12, so that the position of the grinding area formed by the grinding belt 60 can be adjusted, which can be adapted to different specifications of car control levers, effectively expanding the adaptability range of the device to different processing needs. The support wheel 22 on the support plate 20 and the drive wheel 12 driven by the drive motor 11 together with the two sets of driven wheels 41 on the displacement plate 40 form a multi-point support structure, which makes the grinding belt 60 tensioned between them. With the power output of the drive motor 11, the grinding belt 60 can be guaranteed to run smoothly, reduce deviation and vibration, and improve the uniformity and precision of the surface treatment of the car control lever. The adjustment component 30 acts directly on the displacement plate 40 to achieve precise adjustment of the position of the driven wheel 41. Combined with the fixing effect of the base 10, the device can first be stably adjusted by adjusting the position of the displacement plate 40 through the adjustment component 30, and then the drive motor 11 drives the drive wheel 12 to drive the grinding belt 60 to rotate, which simplifies the operation process and improves the convenience of debugging and use.

[0020] Specifically, the displacement plate 40 is provided with a grinding back plate 44, which is disposed between two sets of driven wheels 41; Two sets of connecting plates 43 are symmetrically arranged on the grinding back plate 44, and the connecting plates 43 are connected to the displacement plate 40.

[0021] In this embodiment, the grinding back plate 44 is disposed between the two sets of driven wheels 41, which can form a rigid support for the grinding belt 60 between the two sets of driven wheels 41. This effectively prevents the grinding belt 60 from being excessively deformed or dented due to force when the car control lever comes into contact with the grinding belt 60 for grinding, ensuring the contact stability and fit between the grinding belt 60 and the surface of the control lever, thereby significantly improving the uniformity and precision of the surface treatment.

[0022] Specifically, the connecting plate 43 is provided with a connecting groove 42, and a bolt for connecting to the displacement plate 40 is provided in the connecting groove 42; The displacement plate 40 is also provided with a placement plate 50, and a placement support rod 51 is provided between the placement plate 50 and the displacement plate 40. The placement support rod 51 is connected to the placement plate 50 and the displacement plate 40 by bolts.

[0023] In this embodiment, a connecting slot 42 is provided on the connecting plate 43 and is connected to the displacement plate 40 with bolts. By reserving an adjustment margin in the length direction of the connecting slot 42, the position of the grinding back plate 44 relative to the displacement plate 40 can be finely adjusted within a certain range, thereby adapting to grinding belts 60 of different thicknesses and curvatures or automotive control levers with different surface treatment requirements. This solves the problem of limited adaptability caused by the inability to adjust the position of the grinding back plate 44 under the traditional fixed connection method. At the same time, the bolt connection can form a stable lock after adjustment, ensuring the reliability of the support of the grinding back plate 44.

[0024] Specifically, the adjustment component 30 includes an adjustment sleeve 32, which is connected to the support plate 20; The adjusting sleeve 32 is provided with an adjusting through hole 37, and an adjusting rod 31 is slidably disposed in the adjusting through hole 37. The adjusting rod 31 is connected to the displacement plate 40.

[0025] In this embodiment, the adjusting sleeve 32 is fixedly connected to the support plate 20, and its internal adjusting through hole 37 provides axial sliding guide constraint for the adjusting rod 31, which can limit the radial offset or shaking of the adjusting rod 31 during the adjustment process. Since the adjusting rod 31 is directly connected to the displacement plate 40, the guide structure can guide the displacement plate 40 and the two sets of driven wheels 41 to move smoothly in the preset direction, ensuring that the distance adjustment between the driven wheel 41 and the drive wheel 12 is accurate and controllable, thereby realizing the accurate positioning of the grinding area formed by the grinding belt 60, effectively solving the positioning deviation problem caused by the lack of guide adjustment, and improving the accuracy and consistency of surface treatment.

[0026] Specifically, an adjusting plate 35 is provided in the adjusting through hole 37, and an adjusting screw 34 is rotatably provided on the adjusting plate 35; The adjusting rod 31 has an internal threaded hole 33, and the adjusting screw 34 is threadedly fitted into the internal threaded hole 33.

[0027] In this embodiment, the adjusting plate 35 is provided with a rotating adjusting screw 34. The adjusting screw 34 and the internal threaded hole 33 of the adjusting rod 31 form a threaded transmission structure, which can convert the rotational motion of the adjusting screw 34 into the linear displacement of the adjusting rod 31. The adjustment rod 31 and the displacement plate 40 can be adjusted slightly by the pitch accuracy of the thread, which significantly improves the accuracy of the distance adjustment between the driven wheel 41 and the driving wheel 12, ensures the accurate positioning of the grinding area formed by the grinding belt 60, and effectively solves the problem of insufficient positioning accuracy in the traditional sliding adjustment method.

[0028] Specifically, the cross-sections of the adjusting through hole 37 and the adjusting rod 31 are polygonal; The adjusting plate 35 is also provided with an external hexagonal prism 36, which is connected to the adjusting screw 34 and is rotatably mounted on the adjusting plate 35.

[0029] In this embodiment, the adjusting through hole 37 and the adjusting rod 31 are fitted with a polygonal cross section. The polygonal structure can form a circumferential limiting constraint, which effectively restricts the rotational movement of the adjusting rod 31 within the adjusting through hole 37, allowing it to slide linearly along the axial direction of the adjusting through hole 37. This design avoids the displacement plate 40 and the two sets of driven wheels 41 from being misaligned due to the rotation of the adjusting rod 31, ensuring that the distance adjustment between the driven wheel 41 and the drive wheel 12 is accurately performed in the preset direction, thereby ensuring the positioning accuracy of the grinding area of ​​the grinding belt 60 and solving the problem of circumferential movement that is easy to occur with the circular cross section fit.

[0030] Specifically, the displacement plate 40 is provided with an arc-shaped through groove 45, and the adjusting rod 31 is provided with a first adjusting bolt 38 and a second adjusting bolt 39; The first adjusting bolt 38 is connected to the displacement plate 40, and the second adjusting bolt 39 is disposed in the arc-shaped through groove 45. The arc-shaped through groove 45 is coaxially disposed with the first adjusting bolt 38, so that the displacement plate 40 rotates around the axis of the first adjusting bolt 38 to adjust the position of the two sets of driven wheels 41.

[0031] In this embodiment, the displacement plate 40 is connected to the adjustment rod 31 via the first adjusting bolt 38. It is in cooperation with the sliding fit between the arc-shaped through groove 45 and the second adjusting bolt 39. The arc-shaped through groove 45 and the first adjusting bolt 38 are coaxially arranged, which allows the displacement plate 40 to rotate around the axis of the first adjusting bolt 38. This drives the two sets of driven wheels 41 to rotate synchronously to change their spatial angle, thereby adjusting the tilt posture of the grinding belt 60. This design can adapt to surfaces with different curvatures of automotive control levers, such as bent parts and arc sections, solving the problem that traditional fixed-angle structures cannot fit complex curved surfaces and significantly improving the adaptability of the device to the surface treatment of irregular workpieces.

[0032] Specifically, a movable rod 21 is hinged to the support plate 20, and the support wheel 22 is mounted on the movable rod 21; The movable rod 21 is provided with a movable screw 25, and the support plate 20 is provided with a movable sleeve 26, with the movable screw 25 threaded into the movable sleeve 26.

[0033] In this embodiment, the movable rod 21 is hinged to the support plate 20. With the threaded engagement of the movable screw 25 and the movable sleeve 26, the movable rod 21 can be driven to rotate around the hinge point by rotating the movable screw 25, thereby achieving precise adjustment of the position of the support wheel 22. This design can flexibly adjust the relative distance between the support wheel 22 and the drive wheel 12 and the driven wheel 41, thereby adapting to grinding belts 60 of different lengths and thicknesses. This solves the limitation that traditional fixed support structures cannot adapt to a variety of belts and significantly expands the device's adaptability to grinding belts 60.

[0034] Specifically, the movable screw 25 is provided with a movable connecting part 23, the movable screw 25 is rotatably mounted on the movable connecting part 23, the movable connecting part 23 is hinged to the movable rod 21, and the movable sleeve 26 is hinged to the support plate 20; The outer wall of the movable screw 25 is provided with a toggle hexagonal block 24.

[0035] In this embodiment, the movable connecting part 23 is hinged to the movable rod 21 and rotatably connected to the movable screw 25, and the movable sleeve 26 is hinged to the support plate 20, forming a multi-degree-of-freedom hinged adjustment system. This structure allows the movable screw 25 to adapt to the relative position changes between the movable rod 21, the movable screw 25, and the movable sleeve 26 through angle compensation of each hinge node when driving the movable rod 21 to rotate around the hinge point between it and the support plate 20. This effectively avoids the problem of jamming or sticking caused by structural rigidity interference during the adjustment process, and significantly improves the smoothness and flexibility of the position adjustment of the support wheel 22.

[0036] 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.
