Combined protective cover for linear cutting machine screw guide rail

Abstract

The invention discloses a combined protective cover for a linear cutting machine screw guide rail and relates to the field of combined protective covers mounted around carriages for protecting screw guide rails under the carriages. A left sliding rail (8), a left sliding rail mounting bending plate (10), a left spring (12), a right sliding rail (9), a right sliding rail mounting bending plate (11) and a right spring (13) are mounted between both sides of a front outer protective cover body (1) and a front inner protective cover body (5) as well as on both sides of a rear outer protective cover body (3) and a rear inner protective cover body (6), so that the front outer protective cover body (1) and the front inner protective cover body (5) as well as the rear outer protective cover body (3) and the rear inner protective cover body (6) are slidably connected to each other respectively, and a left connecting protective cover body (2) and a right connecting protective cover body (4) are mounted between both left and right sides of the front outer protective cover body (1) and the rear outer protective cover body (3) to form the combined protective cover for the screw guide rail under the carriage. The combined protective cover for the linear cutting machine screw guide rail is compact in structure, small in space size, free of noise and good in protection.

Description

technical field [0001] The invention relates to a combined protective cover for a lead screw guide rail of a wire cutting machine tool, which relates to the field of a combined protective cover which is installed around a carriage and protects the lead screw guide rail under the carriage. Background technique [0002] In the past, the protection methods for the screw and guide rail under the carriage of the wire cutting machine tool were often protected by organ-type artificial leather curtains or three-layer sheet metal superimposed protection. The disadvantages are as follows: [0003] 1. Install sheet metal shields at both ends of the guide rails of the upper and lower carriages of the X-axis and Y-axis, and install an organ-type leather curtain in the inner cavity of the sheet metal shield. One end of the leather curtain is connected to the carriage, and the other end Connected with the sheet metal cover, when the carriage moves in the X-axis and Y-axis directions, the p...

[0004] 2. On the guide rails of the upper and lower pallets of the X-axis and Y-axis, three layers of sheet metal are superimposed for protection, that is, a layer of floating sheet metal that can slide along the X-axis and Y-axis is installed between the two fixed sheet metals protection, but this structure takes up a lot of space, and the sliding friction resistance of the floating sheet metal is large, which affects the movement accuracy of the carriage and generates noise
