介绍一种直接在汽车上镗削制动鼓的装置(见图)。在由两个30号槽钢焊成的框架2上紧固一虎钳6,虎钳的固定钳口换一滑板1。刀架的横向部分3和夹刀器4就固定在此滑板上。由专门的限制器防止刀架侧移。在镗削制动鼓之前,汽车用千斤顶顶起,并且支架支住,然后取下车轮,而制动鼓5的情况如图所示。此装置放在地上,但要放平。起动汽车发动机,镗削左侧制动鼓时挂头档,镗削右侧制动鼓时挂倒
Describe a device that bores the brake drum directly on the car (see picture). A vise 6 is fastened to the frame 2 welded by two No. 30 channel steel. The fixing jaws of the vise are exchanged for a sliding plate 1. The transverse part 3 of the tool holder and the gripper 4 are fastened to this slide. A special limiter prevents the carriage from being displaced sideways. Before boring the brake drum, the truck jack is lifted and the bracket is supported, and then the wheel is removed. The condition of the brake drum 5 is as shown. Place the unit on the ground, but level it down. Start the car engine, hang the first gear when boring the left brake drum, hang the right brake drum when boring
