[0002] At present, linear guides are important parts in machine tools. They are generally used in high-precision or high-speed linear reciprocating motion occasions, and can bear a certain torque, and can achieve high-precision linear motion under high load. The linear guide is 4 meters long as a whole, and is cut into different lengths according to usage requirements. After the guide is cut, there will be burrs on the end of the guide, which will affect the installation of the slider in the next sequence. Therefore, the burrs on the end of the guide need to be removed manually. Workers use handheld sandpaper or abrasives to manually grind the end of the guide to remove the burrs. This method is simple and easy, but the efficiency is low, and the process depends on the experience and skills of the workers. It is difficult to ensure that the burrs can be completely removed from each end of the guide, which affects the installation of the slider in the next sequence. In addition, the processing efficiency is low, and it is impossible to batch process linear guides.

[0003] Therefore, a linear guide rail end face automatic chamfering device is needed to solve the above technical problems. Utility Model Content
