[0002] The fender, also called the wing, is the outer panel of the car body that covers the wheels. It is named because the shape and position of this part on the old car body resemble bird wings. According to the installation position, it is divided into front fenders and rear fenders. The front fender is installed at the front wheel, and the maximum limit space when the front wheel rotates and bounces must be guaranteed. Therefore, the designer will use the "wheel bounce diagram" to verify whether the design size of the fender is appropriate according to the selected tire model size.
[0003] There are many burrs and protrusions on the existing fender semi-finished products. At the same time, a pneumatic grinder is used to grind the burrs and protrusions on the fender to improve the quality of the fender. Since the pneumatic grinder needs to be held tightly by hand, when users with smaller hands hold the pneumatic grinder from the top, the pneumatic grinder may fall off the hand due to insufficient stability, which may cause damage to the pneumatic grinder. For this reason, we provide a grinding device for fender processing. Utility Model Content
