Description

A grinding and derusting machine tool for the raceway of amphibious tank turret raceway

technical field

The invention relates to a grinding and derusting machine tool for the raceway of a turret raceway of an amphibious tank.

Background technique

Due to the harsh working environment of the amphibious tank, the turret seat ring is easily eroded and polluted by foreign matter such as smoke, sea water, dust, etc., which leads to the corrosion of the raceway of the turret seat ring and affects the working performance of the tank. Carry out "grinding and derusting" maintenance work. At present, the army maintains the turret ring by lifting the tank turret that needs maintenance, decomposing the inner and outer rings of the turret, and then having the maintenance personnel perform grinding and derusting work; then adding grease; finally installing the turret ring and the turret . The existing grinding work adopts the forming method, which requires that the contour curve on the cross section of the grinding part must be consistent with the longitudinal section shape of the raceway (busbar), and then cooperate with the grinding tool to rotate around the workpiece axis (wire), so that the workpiece can be polished All surfaces to be sanded to remove rust. The grinding process is as follows: the maintenance personnel hold the angle grinder to grind the longitudinal section of the surface to be polished, and slowly circle around the axis of the workpiece (wire) to perform the grinding process. The maintenance personnel need to check the grinding effect of the polished position at any time. If Where there are omissions, it needs to be re-polished. This manual maintenance method is not only difficult to guarantee the maintenance quality, but also takes a long time to maintain, has low efficiency, high labor intensity, and requires high physical fitness of the maintenance personnel.
