Description

Technical Field

[0001] The utility model belongs to the technical field of clamps, in particular to an electrical automation clamp. Background Art

[0002] A fixture is a tool or device that fixes the workpiece to maintain its stability and accurate position during the machining process. It is usually used in processes such as machining, welding, assembly and testing, and can improve production efficiency and machining accuracy. Among them, the function of a machining fixture is to fix metal or other material workpieces for machining operations such as milling, drilling and turning.
