[0029] The placement plate 4 is provided with a guide portion 4b, which is arranged in an inclined structure for guiding the grinding debris.

[0030] A filter screen 4a is provided on the guide portion 4b, and the filter screen 4a is made of a high-hardness metal material and is used to support the automobile parts and promote the polishing of the automobile parts.

[0031] The limiting roller 7 has a structure with large ends and a small middle part. The two ends are used to limit the grinding belt 3, and the middle part is used to avoid the grinding belt 3 to prevent the grinding belt 3 from being damaged by excessive friction of the limiting roller 7.

[0032] The end of the telescopic tube 9 is provided with bristles for cleaning the grinding debris on the surface of the grinding belt 3 .

[0033] First, install the grinding device for automobile accessories at the position where it is needed, and then the staff removes the first connecting plate 5 and the second connecting plate 6. Then the staff installs the grinding belt 3 on the vertical belt grinder 2, and at the same time passes the grinding belt 3 through the gap between the corresponding two limiting rollers 7, and then installs the first connecting plate 5 and the second connecting plate 6 back to their original positions, and drives the corresponding limiting roller 7 to rotate through the torsion spring at the connection between the upper first connecting plate 5 and the second connecting plate 6, that is, drives the corresponding limiting roller 7 to rotate clockwise from the perspective of looking from right to left, and at the same time, drives the corresponding limiting roller 7 to rotate through the torsion spring at the connection between the lower first connecting plate 5 and the second connecting plate 6, that is, drives the corresponding limiting roller 7 to rotate from right to left. The viewing angle rotates counterclockwise, that is, the grinding belt 3 is tightened by the cooperation of the upper and lower first connecting plates 5 and the second connecting plates 6, the limiting roller 7 and the torsion spring, so that the grinding belt 3 is pushed forward a distance, which is used to tighten the grinding belts 3 of different sizes, and then the vertical belt grinder 2 is controlled to drive the grinding belt 3 to rotate, that is, the grinding belt 3 is driven to rotate counterclockwise from the right to the left viewing angle, and then the staff puts the auto parts to be polished on the placement plate 4, and then the staff pushes the auto parts to make them approach and contact the grinding belt 3 to perform the grinding work, and then squeezes the grinding belt 3 to make the grinding belt 3 concave inward, and at the same time, the grinding belt 3 moves the limiting roller 7 to follow the movement, so that the limiting roller 7 drives the second connecting plate 6 to follow the movement The second connecting plate 6 is limited by the first connecting plate 5, forcing the upper second connecting plate 6 to rotate with the connection with the first connecting plate 5 as the rotation center, and the second connecting plate 6 rotates counterclockwise from the perspective of looking from right to left, and in this way, the grinding belt 3 is kept taut to ensure that the grinding belt 3 is in a taut state during the grinding process to improve the grinding efficiency. After long-term grinding work, the grinding belt 3 will inevitably wear out. Under this premise, when the force of the staff pushing the auto parts is too large, the grinding belt 3 will break. The main part of the breaking is the position where it contacts the auto parts. When the auto parts break, under the action of the torsion spring between the upper first connecting plate 5 and the second connecting plate 6, the corresponding The second connecting plate 6 and the limiting roller 7 rotate counterclockwise, and at the same time, the torsion spring between the first connecting plate 5 and the second connecting plate 6 below forces the corresponding second connecting plate 6 and the limiting roller 7 to rotate clockwise, that is, the second connecting plate 6 drives the corresponding first magnetic block 6a to follow and move close to the corresponding second magnetic block 10a on the third connecting plate 10, and then the first magnetic block 6a and the second magnetic block 10a are magnetically attracted to each other, and the second magnetic block 10a drives the third connecting plate 10 to follow and move to stretch the telescopic tube 9 and the telescopic rod 11, that is, the two ends of the broken grinding belt 3 are fixed by the second connecting plate 6, the limiting roller 7 and the telescopic tube 9, so as to prevent the broken grinding belt 3 from being driven by the vertical belt grinder 2, causing the broken grinding belt 3 to injure the staff;

[0034] Before the grinding work begins, the staff first uses an external vacuum cleaner to connect with the square connecting pipe 8, and during the grinding process, the debris produced by the grinding belt 3 first passes through the filter 4a, and then moves downward under the guidance of the guide part 4b, so as to avoid the accumulation of the debris produced by the grinding on the placement plate 4, affecting the subsequent grinding work, and the debris attached to the grinding belt 3 is cleaned by the bristles on the telescopic tube 9, and the external vacuum cleaner is controlled to absorb the cleaned debris through the square connecting pipe 8 and the telescopic tube 9.

[0035] Example 2

[0036] On the basis of the above-mentioned embodiment 1, Figure 5-6 As shown, it also includes an extrusion component, which includes a fourth connecting plate 101, a slide bar 102, a spring 103, an air bag 104 and an air intake pipe 105; two symmetrically arranged fourth connecting plates 101 are fixedly connected to the vertical belt grinder 2; each fourth connecting plate 101 is slidably connected to a slide bar 102; another two symmetrically arranged slide bars 102 are slidably connected to the vertical belt grinder 2; all the slide bars 102 are fixedly connected to the springs 103; the other ends of the two upper springs 103 are respectively fixedly connected to the fourth connecting plates 101; the other ends of the two lower springs 103 are fixedly connected to the vertical belt grinder 2; the two slide bars 102 on the same side are commonly connected to the air bag 104; the air bag 104 is in contact with the grinding belt 3; each air bag 104 is connected to the air intake pipe 105.

[0037] The outer surface of the airbag 104 is covered with a hard protective shell, and the portion that fits the sanding belt 3 is not provided with a hard protective shell, so that the airbag 104 is limited to expand only backwards to fit the sanding belt 3.

[0038] The left and right ends of the grinding belt 3 are made of rubber material, which is used to fit the airbag 104 to prevent the airbag 104 from being subjected to excessive friction and causing damage to the airbag 104.

[0039] First, the staff uses an external air injection device to connect with the air inlet pipe 105, and then controls the external air injection device to inject gas into the airbag 104 through the air inlet pipe 105 to expand the airbag 104, so that the airbag 104 fits the grinding belt 3 to adapt to the grinding belt 3 of different thicknesses. At the same time, the grinding belt 3 is restricted by the first connecting plate 5, the second connecting plate 6 and the limiting roller 7 to be pushed forward for a distance, and then the slide bar 102 and the airbag 104 are pushed forward to stretch the spring 103. Then, during the grinding process, when the automobile parts squeeze the grinding belt 3 for grinding, the grinding belt 3 deforms backward, causing the spring 103 to lose its restriction and then drives the slide bar 102 to push the airbag 104, so that the airbag 104 is close to the grinding belt 3. After completing a grinding action, the staff moves the automobile parts away from the grinding belt 3, and the grinding belt 3 loses the automobile parts. The spring 103 is pressed against the upper edge of the sliding bar 102 to push the airbag 104, and the spring 103 is pressed against the lower edge of the sliding bar 102 to push the airbag 104, so that the spring 103 is pressed against the lower edge of the sliding bar 102 to push the airbag 104, so that the spring 103 is pressed against the upper edge of the sliding bar 102 to push the airbag 104, so that the spring 103 is pressed against the upper edge of the sliding bar 102 to push the airbag 104, so that the spring 103 is pressed against the upper edge of the sliding bar 102 to push the airbag 104, so that the spring 103 is pressed against the upper edge of the sliding bar 102 to push the airbag 104, so that the spring 103 is pressed against the upper edge of the sliding bar 102 to push the airbag 104, so that the spring 103 is pressed against the upper edge of the sliding bar 102 to push the airbag 104, so that the spring 103 is pressed against the upper edge of the sliding bar 102 to push the airbag 104, so that the spring 103 is pressed against the upper edge of the sliding bar 102 to push the airbag 104, so that the spring 103 is pressed against the upper edge of the sliding bar 102

[0042] The surface of the water bag 204 is provided with a wear-resistant coating to reduce friction.

[0043] First, the staff uses an external water injection device to connect with the water inlet pipe 203, and then uses an external drainage device to connect with the drainage pipe 205. During the polishing process of the auto parts, the auto parts squeeze the polishing belt 3 to make the polishing belt 3 fit with the water bag 204, and then control the operation of the water injection device and the drainage device to circulate the water inside the water bag 204 to reduce the temperature of the polishing belt 3 caused by polishing. The water bag 204 can be better used for auto parts of different shapes and sizes. When the polishing belt 3 is broken, the water bag 204 can cooperate with the air bag 104 to clamp the polishing belt 3, and further limit the broken polishing belt 3 to ensure the safety of the front staff.
