[0001] The utility model relates to the technical field of linear guide rails, in particular to an anti-warping mechanism for linear guide rails. Background Technique
[0002] The function of the linear guide rail movement is to support and guide the moving parts to make reciprocating linear motion in a given direction. According to the friction property, the linear motion guide rail can be divided into sliding friction guide rail, rolling friction guide rail, elastic friction guide rail, fluid friction guide rail and other types. Linear bearings are mainly used in automated machinery, such as imported machine tools, bending machines, laser welding machines, etc. Of course, linear bearings and linear shafts are used in pairs. Like linear guide rails are mainly used in mechanical structures with relatively high precision requirements. There is no intermediate medium between the moving element and the fixed element of the linear guide rail, but rolling steel balls are used.

[0004] Therefore, it is necessary to provide an anti-warping mechanism for linear guide rails to solve the above technical problems. Content of the Utility Model

[0024] Clamping plates 3, the clamping plates 3 are respectively arranged at both ends of the top of the mounting seat 21, a moving groove 32 is opened inside the clamping plates 3, a threaded rod 34 is threadedly connected to the top of the clamping plates 3, and a pressing plate 35 is arranged at the bottom of the threaded rod 34.
[0025] A crank 25 is fixedly installed at one end of the rotating shaft 24.
[0026] The bottom of the clamping plate 3 is fixedly installed with a slider 31, and the bottom of the slider 31 is attached to the bottom of the inner side of the chute 22.

Then, the bottom of the screw rod 34 presses the pressing plate 35, and then the bottom of the pressing plate 35 presses on the top of the guide rail. In this way, it can play an effect of preventing the guide rail from warping.
