Description

Technical Field

[0001] The utility model relates to the technical field of turning fixtures, in particular to a turning mechanism. Background Art

[0002] Turning is an important metal cutting method that mainly uses a rotating cutting tool to cut the workpiece to achieve the desired shape and size. The tool is used to cut on the rotating material and form the desired shape by removing excess material. During the turning process, the workpiece is fixed to the spindle of the lathe by a fixture and rotated, while the cutting tool rotates on the surface of the workpiece through the tool holder. By controlling parameters such as cutting depth, feed speed and rotation speed, high-precision processing can be achieved.

[0003] In the traditional turning process, the stability and reliability of the center fixture have always been important factors affecting the processing quality and efficiency. There are some problems with the turning center fixtures used in the past. First, during the turning process, due to design defects of the fixture or insufficient clamping force, the center is prone to turning, which may lead to a decrease in processing accuracy and cause the workpiece to be scrapped, increasing production costs. Secondly, when clamping the workpiece, the traditional fixture is likely to leave clamping marks on the workpiece surface. These clamping marks will affect the surface quality of the workpiece, and additional surface treatment steps will be required later, which increases the complexity of production. Therefore, a turning mechanism is needed to meet people's needs. Utility Model Content
