Protection device of track of machine tool

Abstract

The invention discloses a protection device of a track of a machine tool. The protection device comprises a guide rail stretching out of a base of the machine tool. A protection cover is installed on the portion, stretching out of the base, of the guide rail and comprises a hollow cover body. The cover body comprises five sliding covers, wherein the five sliding covers are overlapped, can slide relative to one another, and are connected through connecting rods. A supporting frame is connected to the sliding cover of the innermost layer, and more than three idler wheels capable of rolling on the guide rail are connected to the supporting frame. The sliding covers of the protection cover can be pulled to make the idler wheels slide on the guide rail; because the guide rail stretches out of the base of the machine tool, the sliding covers will not be affected when sliding on the guide rail and can very smoothly move without shaking, and neither the surface quality of the guide rail nor the service life of the guide rail will be affected.

Description

technical field [0001] The invention relates to a protection device for a rail of a machine tool. Background technique [0002] At present, some machine tools are exposed in the air and there is no protective cover on the guide rails, so that some dust and other pollutants will be attached to the guide rails, which will affect the normal movement of the workbench. Or the protective cover is installed on the guide rail of some machine tools, but the guide rail does not protrude from the base of the machine tool. Instead, a receiving rod with the same size as the guide rail is installed on the base corresponding to the position of the guide rail to accept the protective cover. There is a gap between the receiving rod and the guide rail. When the roller on the protective cover rolls through the gap, it is often affected, and it is not easy to move from the receiving rod to the guide rail, or it will shake when rolling over, which will make the protective cover Collision with t...
