The invention relates to the technical field of
grinding equipment, and discloses an automobile part
machining device. The device comprises a large-model
grinding box, a protection plate is hinged tothe top of the front face of the
grinding box through a hinge, a rotating mechanism is arranged at the bottom in the grinding box, the rotating mechanism comprises a transmission box, a first rotatingshaft, a
rotating disc, a
crank, a first gear, a second gear, a second rotating shaft, a moving block, a threaded hole, a lead screw, a fixed rotary knob, sliding grooves, a movable frame, a fixed plate, a
threaded rod, chucks, anti-skid pads and an adjusting rotary knob, the transmission box is fixedly installed at the bottom in the grinding box, the first rotating shaft penetrates through the top of the transmission box and is in rotary connection with the transmission box, the
rotating disc is fixedly connected to the top of the first rotating shaft, the
crank is rotationally connected with the top of the
rotating disc, the first gear is fixedly installed on the portion, located in the transmission box, of the first rotating shaft, and the second gear is engaged with the first gear. The automobile part
machining device solves the problems that the surfaces of automobile parts are polished unevenly and the automobile parts cannot be assembled.
