Description

Technical Field

[0002] A fixture is a process device used to quickly fasten the workpiece during processing to keep the machine tool, tool, and workpiece in the correct relative position. That is to say, tooling fixtures are indispensable parts of mechanical processing. Driven by the development of machine tool technology towards high speed, high efficiency, precision, compound, intelligent, and environmental protection, fixture technology is developing towards high precision, high efficiency, modular, combined, universal, and economical directions. When processing workpieces on machine tools, in order to make the surface of the workpiece meet the technical requirements of size, geometry, and relative position accuracy with other surfaces specified in the drawings, the workpiece must be installed (positioned) and clamped (clamped) before processing.

[0003] For example, a multi-station clamp for CNC machine tools disclosed in a Chinese patent document (publication number: CN220240784U) can clamp multiple cylinder flanges at one time and can position the cylinder flanges up and down, with good processing effect. However, when clamping and loosening the cylinder flanges, it is necessary to turn the locking screws one by one, resulting in a waste of time and reduced efficiency. In addition, the adjustable range of the locking V-block is too small to adapt to cylinder flanges of various sizes. Utility Model Content
