Description

Technical Field

[0002] Guide rail (TTWguide): A device with grooves or ridges made of metal or other materials that can bear, fix, guide moving devices or equipment and reduce their friction. The longitudinal grooves or ridges on the surface of the guide rail are used to guide and fix machine parts, special equipment, instruments, etc. Guide rails are also called slide rails, linear guides, and linear slides. They are used in linear reciprocating motion occasions. They have higher rated loads than linear bearings, and can bear a certain torque. They can achieve high-precision linear motion under high loads. After the production of the guide rail, it is usually necessary to test the size specifications of the guide rail and the sliding effect of the slider installed on it. During the test process of the guide rail, it is easy to affect the test accuracy due to changes in the position of the guide rail. Therefore, a guide rail test positioning device is required. However, the existing guide rail test positioning device is not convenient for positioning guide rails of different lengths, resulting in the guide rail shaking during the test process, thereby affecting the measurement accuracy. To solve the above problems, we have launched the following device. Utility Model Content
