Three-jaw chuck clamping reliability detection device and judgment method

Abstract

The invention discloses a three-jaw chuck clamping reliability detection device and a judgment method. The three-jaw chuck clamping reliability detection device comprises a three-jaw chuck; circumferential-direction detection dial indicators and end-surface-direction detection dial indicators are symmetrically mounted on the two sides of three clamping jaws of the three-jaw chuck through fixing supports respectively; the end-surface-direction detection dial indicators are mounted on the side close to the end surface of a workpiece, and probes of the end-surface-direction detection dial indicators make contact with the end surface of the workpiece; probes of the circumferential-direction detection dial indicators make contact with the circumferential surface of the workpiece. Whether scrap iron exists or not can be deduced through the change of readings of the circumferential-direction detection dial indicators and the end-surface-direction detection dial indicators, if the scrap iron exists, the approximate position of the scrap iron can be deduced according to the change rule of the readings, it is guaranteed that the machined workpiece is not affected by the scrap iron, machining errors are reduced, the machining precision is guaranteed, the number of waste products is reduced, and the cost can be saved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of three-jaw chuck reliability measurement, in particular to a three-jaw chuck clamping reliability detection device and a judging method. Background technique [0002] In the modern machinery manufacturing industry, turning is one of the most important forming methods for metal parts. During the turning process, the existence of iron filings greatly affects the machining accuracy. If the iron filings are not handled properly, it will affect the processing stability of the machine tool. Thus affecting the machining accuracy. When the three-jaw chuck is used to position and clamp the workpiece, if there are iron filings in the circumferential direction of the workpiece and on the positioning end surface, especially the micron-sized iron filings cannot be judged by the naked eye, it is easy to cause positioning errors and processing errors. Therefore, there is a need for a three-jaw chuck clamping reliability...
