A grinding mechanism 3 is movably connected to one side of the positioning frame 2. The grinding mechanism 3 includes a transmission wheel 31, a movable plate 32, and a sanding belt 33. The transmission wheel 31 is rotatably installed at one corner of the base 1. The movable plate 32 is located at the opposite corner of the transmission wheel 31. Driven wheels 34 are rotatably installed at the two corners of the movable plate 32. The sanding belt 33 is movably connected to the surfaces of the driven wheels 34 and the transmission wheel 31. A control lever 35 is rotatably connected to one end of the positioning frame 2. An adjusting wheel 36 is rotatably installed on one side of the control lever 35. The adjusting wheel 36 overlaps the inner side of the sanding belt 33.

[0019] The specific setup and function of this embodiment are described below. The reduction motor 4 is fixed to the base 1. During operation, the reduction motor 4 drives the transmission wheel 31 to rotate. The transmission wheel 31 drives the driven wheel 34 to rotate via the sanding belt 33, causing the sanding belt 33 to form a cyclic transmission, thereby achieving the grinding of the automotive parts surface. The positioning frame 2 has a fixed edge and one side is movably connected to the grinding mechanism 3. The movable plate 32 is located at the opposite corner of the transmission wheel 31. The driven wheel 34 at its corner, together with the transmission wheel 31, supports the sanding belt 33. The control lever 35 is rotatably connected to one end of the positioning frame 2, and its side adjustment... The adjustable wheel 36 overlaps the inner side of the sanding belt 33. By rotating the control lever 35, the angle of the sanding belt 33 can be adjusted by the adjusting wheel 36 to ensure that the sanding belt 33 maintains a proper position during the sanding process and ensures the sanding effect. The structure of this belt sander uses the geared motor 4 to drive the transmission wheel 31 and the driven wheel 34 to cooperate with the sanding belt 33 to achieve the sanding function. The adjusting wheel 36 can flexibly adjust the angle of the sanding belt 33. The positioning frame 2 ensures the structural stability. It has the beneficial effects of stable transmission, convenient adjustment, high sanding efficiency and guaranteed sanding quality, and can be effectively applied to the surface sanding of automotive parts.

[0020] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, a first positioning rod 38 is fixedly installed on one side of the end of the control lever 35. The first positioning rod 38 is perpendicular to the control lever 35. A support base 39 is fixedly installed at the corner of the base 1. The support base 39 is located on one side of the movable plate 32. A second positioning rod 310 is fixedly installed on one side of the support base 39. The second positioning rod 310 is parallel to the first positioning rod 38. An electric cylinder 37 is rotatably installed on the outer wall of the second positioning rod 310. One end of the piston rod of the electric cylinder 37 is rotatably connected to the first positioning rod 38. A guide rod 312 is fixedly connected to one side of the movable plate 32. One end of the guide rod 312 is inserted into the interior of the positioning frame 2. A strip groove 311 is opened at the junction of the movable plate 32 and the transmission wheel 31. A limit groove 5 is opened on one side of the positioning frame 2.

[0021] The overall effect of this embodiment is as follows: one end of the electric cylinder 37 is rotatably mounted on the second positioning rod 310, which is fixed to one side of the support base 39. The support base 39 is fixed at the corner of the base 1 and located on one side of the movable plate 32. One end of the piston rod of the electric cylinder 37 is rotatably connected to the first positioning rod 38, which is fixed to one side of the end of the control rod 35 and perpendicular to it. When the piston rod of the electric cylinder 37 extends or retracts, it drives the first positioning rod 38 to move, thereby causing the control rod 35 to rotate around its rotatable connection with the positioning frame 2. When the control rod 35 rotates, it drives the adjusting wheel 36 to move, thereby achieving precise adjustment of the angle of the sanding belt 33. The guide rod 312 on one side of the movable plate 32 is inserted into the positioning frame. Inside the 2, a tension spring is fixedly connected between the guide rod 312 and the positioning frame 2 to support the guide rod 312 and ensure the stability of the movement of the movable plate 32. The strip groove 311 at the junction of the movable plate 32 and the transmission wheel 31, as well as the limiting groove 5 on one side of the positioning frame 2, can limit the movement range of the movable plate 32 and prevent it from moving excessively. This structure drives the control lever 35 to rotate through the electric cylinder 37 to realize the electric adjustment of the angle of the sanding belt 33. It has the beneficial effects of high adjustment accuracy and convenient operation. The setting of the guide rod 312, the strip groove 311 and the limiting groove 5 ensures the stability and reliability of the movement of the movable plate 32, improves the working efficiency and service life of the equipment, and can better meet the needs of surface grinding of automotive parts.

[0022] The usage and working principle of this device are as follows: First, check the sanding belt 33 for damage and ensure all connections are secure. Ensure the reduction motor 4 and electric cylinder 37 are functioning correctly. Then, based on the size of the parts to be sanded and the sanding requirements, start the electric cylinder 37. The extension and retraction of its piston rod will drive the first positioning rod 38, causing the control lever 35 to rotate around its connection with the positioning frame 2. This, in turn, drives the adjusting wheel 36 to precisely adjust the angle of the sanding belt 33. The guide rod 312 on one side of the movable plate 32 slides within the positioning frame 2, ensuring stable movement of the movable plate 32. The strip groove 311 and the limiting groove 5 restrict the range of movement of the movable plate 32 to prevent excessive movement. After the angle is properly adjusted, place the car... The parts are fixed on the worktable, so that the surface to be polished is in contact with the sanding belt 33. Then, the geared motor 4 is started, driving the transmission wheel 31 to rotate. The transmission wheel 31 drives the driven wheel 34 to rotate through the sanding belt 33, so that the sanding belt 33 forms a cyclic transmission, and the surface of the automotive parts is polished. During the polishing process, the angle of the sanding belt 33 can be finely adjusted at any time by the electric cylinder 37 according to the polishing effect and needs to ensure the polishing quality. After polishing is completed, the geared motor 4 is turned off first. After the sanding belt 33 has completely stopped rotating, the electric cylinder 37 is released to adjust the angle of the sanding belt 33 to a relaxed state. Finally, the polished parts are removed, and the debris and debris on the equipment are cleaned to prepare for the next use.
