Description

Technical Field

[0001] The utility model relates to the technical field of tool positioning devices, in particular to a tool positioning device for machine tools. Background Art

[0002] Machine tool processing refers to the processing and production of raw materials using machine tools. The cutting processing of machine tools is achieved by the relative motion between the tool and the workpiece. Its motion can be divided into two categories: surface forming motion and auxiliary motion. The surface forming motion is the motion that enables the workpiece to obtain the required surface shape and size. It includes main motion, feed motion and cutting motion. The main motion is the motion that plays a major role in stripping excess material from the workpiece blank. It can be the rotational motion or linear motion of the workpiece, or the rotational motion or linear motion of the tool. The feed motion is the motion in which the tool and the part to be processed of the workpiece move toward each other, so that cutting can continue.

[0003] In the existing technology, the workpiece positioning process is cumbersome and requires manual positioning. Not only can it not be accurately positioned, but it is also inefficient, affecting the on-site workpiece processing efficiency. In addition, the workpiece positioning device used for machine tool processing is not easy to adjust and cannot position workpieces of different specifications, affecting the processing of the workpiece and bringing inconvenience. In addition, during automatic processing, the cylinder specifications cannot meet the specifications of different workpieces, reducing work efficiency. Utility Model Content
