Lathe machining cutting device for hollow slender shaft

Abstract

The invention discloses a lathe machining cutting device for a hollow slender shaft. The lathe machining cutting device comprises a control body, wherein an electric sliding sleeve is fixedly arrangedon the bottom surface of the control body, the electric sliding sleeve is arranged on the top surface of a sliding rail in a front-back sliding mode, a connecting cavity with a leftward opening, a moving cavity and a sliding cavity are formed in the control body, the moving cavity and the sliding cavity are located on the front side of the connecting cavity, the moving cavity is located on the upper side of the sliding cavity, and two sliding columns symmetrical up and down are fixedly arranged between the front wall and the rear wall of the connecting cavity. The lathe machining cutting device adopts a mode of middle stable positioning and clamping and along-shaft rotating to solve the problems that when a hollow shaft workpiece is machined by a lathe, the side of the lathe cannot be positioned in the circle center, due to too long length, rotating shaking is caused, and due to too long length, the jumping error is too large during cutting, and can effectively improve the precision during hollow shaft workpiece lathe cutting machining.

Description

technical field [0001] The invention relates to the technical field of lathe processing, in particular to a lathe processing cutting device for hollow elongated shafts. Background technique [0002] Lathe processing is a part of mechanical processing. There are two main processing forms: one is to fix the turning tool to process the unformed workpiece during rotation; the other is to fix the workpiece, and through the high-speed rotation of the workpiece, the lateral and Longitudinal movement for precision machining; [0003] The method of workpiece rotation and turning tool feed is generally suitable for processing short-distance workpieces. The hollow and slender shaft is too long, so it is very easy to rotate and shake when the lathe is cutting, and it is easy to happen when the turning tool touches The workpiece jumps. In addition, because the shaft is hollow, it is difficult to locate the device on the opposite side of the lathe fixture for workpiece positioning. There...

Problems solved by technology

[0003] The method of workpiece rotation and turning tool feed is generally suitable for processing short-distance workpieces. The hollow and slender shaft is too long, so it is very easy to rotate and shake when the lathe is cutting, and it is easy to happen when the turning tool touches The workpiece jumps. In addition, because the shaft is hollow, it is difficult to locate the device on the opposite side of the lathe fixture for workpiece positioning. There are also some fixtures for auxiliary lathe machining long axes on the market, but this type of clamping is usually only used on two or three sides. The type splint is clamped by soft contact, and the shaft is easy to rub against the splint when it is being processed and rotated, which will still cause machining and cutting errors.
