Problems solved by technology

Especially for the processing of shaft workpieces, in order to realize the simultaneous processing of multiple stations, it is often necessary to erect multiple shaft workpieces on the fixture disk in a circular array. However, for some longer and smaller diameter shaft workpieces In terms of processing, since the processing force is often applied along the radial direction of the workpiece, it is easy to cause the workpiece to bend, which will lead to a greater adverse effect on the processing accuracy of the workpiece.

Abstract

The invention discloses a new type of fixture for precision machine tool parts processing. After each clamping claw assembly clamps and fixes the upper and lower ends of the workpiece or shaft and before starting to process, the lower clamping plate mechanism can Driven by the linear tension driver, the workpiece or shaft is tightened downwards and processed after reaching a certain tension pre-tension force, and the limit and tension detection seat can The tightening force is detected and the linear tensioning driver is feedback-controlled. By setting the tensioning pretensioning force, it can effectively ensure the ability of the workpiece or shaft to resist bending during processing, and at the same time, it can prevent the workpiece from being damaged when the workpiece is tightened. , improve adaptability. The optical calibration assembly of the invention can ensure the accuracy of the workpiece when it is clamped, ensure the coaxial clamping of the upper and lower sides, and improve the machining accuracy of the workpiece.

Description

technical field [0001] Specifically, the invention relates to a novel jig for processing precision machine tool parts, and relates to the related field of mechanical processing equipment. Background technique [0002] At present, in high-precision machining, the clamping accuracy of the fixture is crucial to the machining accuracy of the workpiece. Especially for the processing of shaft workpieces, in order to realize the simultaneous processing of multiple stations, it is often necessary to erect multiple shaft workpieces on the fixture disk in a circular array. However, for some longer and smaller diameter shaft workpieces Generally speaking, during processing, since the processing force is often applied along the radial direction of the workpiece, it is easy to cause the workpiece to bend, which will lead to a greater adverse effect on the processing accuracy of the workpiece. Therefore, how to reduce the influence of this processing force on the deformation of the workp...
