Description

Technical Field

[0001] The utility model belongs to the technical field of guide rail processing and positioning, and in particular relates to an automatic guide rail positioning device. Background Art

[0002] A guide rail is 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. During the production and manufacturing process of the guide rail, it is sometimes necessary to weld other workpieces on its surface, and a guide rail positioning device is required to position the guide rail and the welded workpiece. The traditional guide rail positioning device does not accurately fix the guide rail, and during the welding process, the workpiece to be welded needs to be manually placed on the guide rail, which makes the welding work inconvenient, inefficient, and difficult to ensure quality, which is not conducive to the processing of the guide rail.
