Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and specifically to an automatic linear guide rail cutting machine. Background Technology

[0002] Linear guides are used to support and guide moving parts, and are mainly used in mechanical structures with high precision requirements. According to the actual size of the mechanical equipment, installation space and functional requirements, the linear guides need to be precisely cut to a certain length to ensure the smooth operation of the equipment. The guide rail cutting machine is a commonly used cutting equipment for cutting linear guides.

[0003] Linear guide rail cutting commonly employs manual cutting and automated cutting machine cutting. Manual cutting is flexible and convenient, but it suffers from poor quality, large dimensional errors, and a large workload in subsequent processing. Furthermore, it involves harsh working conditions and low production efficiency. Among automated cutting machines, contour cutting machines produce better workpiece quality. However, because they use cutting molds, they are not suitable for single-piece or small-batch cutting of special dimensions, easily leading to material waste and increased costs.

[0004] In view of this, we propose an automatic linear guide cutting machine to solve the above problems. Utility Model Content
