The present invention provides a sliding surface protection device in which lubricating oil on the sliding surface does not leak to the outside and chips and cutting fluid do not infiltrate into an oil collecting pan of the lubricating oil and mix with the lubricating oil. The cover frame (4) constituting the sliding cover (3) is equipped with a wiper (10) at the lower end that contacts the surface of the overlapping inner cover frame (4), and is provided with a protruding beyond the inner cover frame on the upper back The eave-shaped backboard is formed on the part of the cover frame that descends one step from the upper end, and the upper surface of the cover frame is equipped with sliding shoes that contact the back of the overlapped outer cover frame, and the innermost The cover frame is fixedly installed on the column formed with the sliding surface, and has a bottom plate (14) closing the lower part of the sliding surface, and an oil collecting part for receiving lubricating oil flowing out from the sliding surface is formed on the upper part of the bottom plate (14).
Description
technical field [0001] The present invention relates to a sliding surface protector for protecting a sliding surface of a machine tool from damage such as chips, and more particularly to a sliding surface protector for protecting a sliding surface formed in a vertical direction. Background technique [0002] When the sliding surface is formed in the vertical direction, the sliding surface protection device such as Figure 4 formed as shown. exist Figure 4 In the sliding surface protection device, the sliding cover 22 is applied to the sliding surface protection device. The sliding cover 22 is formed by overlapping and connecting a plurality of cover frames 21 in a telescopic manner. By making the sliding cover 22 move on the sliding surface 23a The body 24 moves up and down to expand and contract, so that the sliding surface 23a is always protected from damage such as cutting chips. Furthermore, an oil collecting pan 25 for recovering lubricating oil flowing out from the s...
