A method and device for automatic deviation correction in hollow shaft machining

Abstract

The invention discloses an automatic deviation correction method and device for processing a hollow shaft, which comprises a lathe body, one side of the lathe body is fixedly connected with a fixing plate, and the upper surface and the lower surface of the surface of the fixing plate are respectively fixedly connected with a pre-deviation correction device and a fine deviation correction device , one end of the rotating rod is fixedly connected with a detector. The invention relates to the technical field of lathe processing. The pre-correction device can be used to measure the hollow shaft to be processed for the first time, so as to determine whether the hollow shaft has a position deviation phenomenon. The pre-deviation correction device will be prepared for the fine deviation correction device. If there is a deviation, it does not need to be detected by the fine deviation correction device, which reduces the detection time of the fine deviation correction device. The detection of the whole plane of the fine deviation correction device greatly improves the accuracy The accuracy of the deviation correction of the hollow shaft can ensure the comprehensive deviation correction of the hollow shaft, and avoid the error of the hollow shaft, which will eventually lead to the scrapping of the hollow shaft and the waste of materials.

Description

technical field [0001] The invention relates to the technical field of lathe processing, in particular to an automatic deviation correction method and device for hollow shaft processing. Background technique [0002] Lathe processing is a part of mechanical processing. There are mainly two processing forms: one is to fix the turning tool and process the unformed workpiece during rotation; the other is to fix the workpiece and rotate the turning tool (tool holder) ) horizontal and vertical movement for precision machining. CNC lathe processing is usually composed of control system, servo system, detection system, mechanical transmission system and other auxiliary systems, which is easy to ensure the accuracy of each processing surface of the workpiece; during processing, the workpiece rotates around a fixed axis, and each surface has the same axis of rotation , so it is easy to ensure the coaxiality requirements between the processing surfaces; 2, the cutting process is rela...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an automatic deviation correction method and device for hollow shaft processing, which solves the problem that when the hollow shaft is processed by a little bit of deviation due to loading. It also leads to the size error of the hollow shaft during processing, which will eventually lead to the scrapping of the hollow shaft and the waste of materials.
