Description

Technical Field

[0002] Linear guides are also called linear guides. The function of linear guides is to support and guide moving parts to perform reciprocating linear motion in a given direction. Depending on the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types. Linear guides are mainly used in mechanical structures with relatively high precision requirements.

[0003] During the processing of linear guides, they need to be fixed with a clamp. However, traditional clamps usually have a simple structure. When clamping longer workpieces such as linear guides, they are prone to shaking, which makes it difficult to ensure processing accuracy. At the same time, it is difficult to adjust the position of the workpiece after clamping, which makes processing inconvenient and affects efficiency. Therefore, technical personnel in this field provide a clamp for linear guide processing to solve the problems raised in the above background technology. Utility Model Content
