Automatic deviation rectifying method and device for machining hollow shaft

Abstract

The invention discloses an automatic deviation rectifying method and device for machining a hollow shaft, and relates to the technical field of lathe machining. The device comprise a lathe body, wherein one side of the lathe body is fixedly connected with a fixing plate, the upper surface and the lower surface of the surface of the fixing plate are respectively fixedly connected with a pre-deviation rectifying device and a fine deviation rectifying device, and one end of a rotating rod is fixedly connected with a detector. The hollow shaft needing machining is measured for the first time through the pre-deviation rectifying device, so that whether the hollow shaft has a position deviation phenomenon or not is determined, the pre-deviation rectifying device prepares for the fine deviation rectifying device, if the position deviation phenomenon exits, the precise deviation rectifying device does not need to perform detection, the detection time of the precise deviation rectifying deviceis reduced, the whole-plane detection of the precise deviation rectifying device greatly improves the accuracy of deviation rectifying of the hollow shaft, the completeness of deviation rectifying ofthe hollow shaft can be guaranteed, and the situation that a hollow shaft has errors, finally, the hollow shaft is scrapped, and the material is wasted is avoided.

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.
