Grinding device for auto parts

Abstract

The invention relates to the technical field of auto parts processing, and discloses a grinding device for auto parts, which includes a frame and a motor. A main bevel gear is fixed on the output shaft of the motor; a support shaft is provided at the bottom of the main bevel gear, and both sides of the support shaft There is a friction plate on the side that is slidingly connected to the main bevel gear. There are bumps fixed on the friction plates, and compression springs are fixed between the bumps. The bottoms of the friction plates are inclined planes that slope downward toward the support shaft; below the main bevel gear It is also equipped with a telescopic cylinder and a support seat. The support seat includes a fixed seat and a sliding seat. The telescopic rod of the telescopic cylinder is fixedly connected to the sliding seat. The sliding seat is slidingly connected with a positioning rod that cooperates with the friction plate. The bottom of the positioning rod is provided with a return spring. ; There is a auxiliary bevel gear rotatably connected to the frame, and the auxiliary bevel gear meshes with the main bevel gear. The frame is provided with a screw, the auxiliary bevel gear drives the screw to rotate, and the nut seat of the screw is fixedly connected to the fixed seat. The invention has a simple structure and can polish and remove burrs from the accessory holes and bottom surfaces of accessories.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a grinding device for auto parts. Background technique [0002] During the processing of auto parts, some accessories such as mounting plates, wind deflectors, brackets and main boards need to be punched. The holes are all for the convenience of installation. There are many ways to punch holes, such as drill drilling, stamping Punching etc. These punching methods are all rough machining, so many metal burrs or plastic burrs will be left on the punched holes. No matter what kind of burrs are easy to scratch the accessory packaging bag, and it is easy to hurt the hands of the installer, so it is necessary to Deal with the remaining burrs after drilling to avoid the above problems. [0003] The existing burr treatment methods are mechanical or manual grinding. However, both grinding methods are used to polish the surface of the accessories, which can only clean the b...

Problems solved by technology

These punching methods are all rough machining, so many metal burrs or plastic burrs will be left on the punched holes. No matter what kind of burrs are easy to scratch the accessory packaging bag, and it is easy to hurt the hands of the installer, so it is necessary to Deal with the remaining burrs after drilling to avoid the above problems

[0003] The existing burr treatment methods are mechanical or manual grinding. However, both grinding methods are used to polish the surface of the accessories, which can only clean the burrs on the surface of the accessories. In fact, the bottom surface of the accessories and the inside of the drilled hole There are still many glitches that are not handled well

When the mounting part passes through the hole for accessories installation, the burrs may increase the resistance of the mounting part and increase the wear of the mounting part, thereby reducing the service life of the mounting part. If the burrs on the bottom surface are not well treated, it will also affect the appearance of the accessories
