Description

Technical Field

The existing steel plate telescopic protective cover generally includes multiple sets of nested protective covers, one end of the multiple sets of protective covers is connected to the machine tool, and the other end is connected to the mobile machining center, so that the telescopic protective cover can be retracted and extended with the mobile machining center to protect the surface of the machine tool.

[0003] It was found during use that the existing steel plate telescopic protective covers have no heat dissipation function between adjacent protective covers. When the machine tool is in use, the heat generated inside will accumulate inside the protective cover, which will cause the temperature of the machine tool to be too high for a long time, affecting the normal use of the machine tool.

The utility model fills the gap between the first protective cover plate and the second protective cover plate and the gap between two adjacent second protective cover plates with a sealing scraper strip, so that the protective cover itself can be more sealed, and the oil or water generated by the machine tool operation will not enter the machine or product, so as to better protect the machine itself, and the noise is greatly reduced during the movement of the second protective cover plate.

[0005] Although the above patent has achieved that the gap between the first protective cover plate and the second protective cover plate and the gap between two adjacent second protective cover plates are filled with sealing scraper strips, which can make the protective cover itself more sealed and the oil or water generated by the machine tool operation will not enter the machine or product; however, the device lacks a quick-release mechanism, which is not convenient for the staff to quickly fix the equipment on the surface of the machine tool. It needs to be fixed by screwing screws, and the operation is more cumbersome.
