A grinding and polishing device for grinding and anti-jamming gaps of parts next to the automobile shell

Abstract

The invention discloses a grinding and polishing device for grinding a part beside an automobile shell and free from getting stuck in a gap. The grinding and polishing device comprises a power connection end, an inflation handle, a connection installation opening, a connection hollow column, a polishing cylinder and a button, wherein the power supply connection end is embedded into the bottom endof the inflation handle and is electrically connected, the connection installation opening is arranged at one end, far away from the power supply connection end, of the inflation handle, the bottom end of the connection hollow column penetrates through the interior of the connection installation opening, one end, far away from an inflation middle shaft, of an inclined air inflation opening is connected with an extendable moving ring, and the outer ring of the extendable moving ring and a soft polishing body penetrate through each other. When the polishing cylinder performs polishing on the automobile part, pressing control is carried out on the button by the outside so that the inner part of the inflation middle shaft is inflated, and an inflation column is pushed out and then carries outthe high-speed rotary grinding; and when the polishing cylinder is smaller than the gap, the polishing cylinder can be taken out and free from being torn off, and the portion, between the gaps, of theshell is free from being deformed.

Description

technical field [0001] The invention belongs to the field of automobiles, and more specifically relates to a grinding and polishing device for grinding anti-jamming gaps of parts beside the automobile shell. Background technique [0002] At present, there are more and more ways to polish auto parts, but because some positions are more special, manual polishing is still indispensable. When the car is almost installed, many internal small parts need to be slightly polished and adjusted, and need to be polished. The position and the shell that the car has been installed are just in the position of the adjacent seat. [0003] Based on above-mentioned inventor's discovery, existing auto parts polishing device mainly has the following deficiencies, such as: [0004] Because the polishing of its small parts requires a cylindrical brush similar to a small brush, it will inevitably move to a position with a gap during the high-speed rotary polishing process. Because the brush is too...

Problems solved by technology

[0006] In order to solve the above-mentioned technology, a cylindrical brush similar to a small brush is needed to polish its small parts. During the high-speed rotary polishing process, it will inevitably move to a position with a gap. Because the brush is too thin, it is easier to get stuck into the car shell. In the gap, if the brush is pulled out forcibly, the bristles of the brush will fall off and be damaged at a light point, and the brush will be intact at a serious point. However, due to the hard pulling of the brush, the two parts between the gap The chip shell is pulled out and deformed, even uneven
