Abstract

The invention relates to the field of machining, in particular to a non-rigid shaft combined machining device. The non-rigid shaft combined machining device comprises a bottom plate which is fixed on a lathe carriage through a wedge, and the bottom plate is fixedly connected with a bottom plate body through a fastening screw and an adjusting screw. The bottom plate body is connected with a machining head and a machine body. The two end faces corresponding to the machining head are each provided with a center, and the centers comprise the front center and the rear center. The front center and the rear center are each provided with a guide sleeve, and the guide sleeves comprise the front guide sleeve and the rear guide sleeve. A guide rail is arranged at one end of the machine body, and the guide rail is connected with a tool apron through a presser. The other end of the machine body 8 is provided with a taper hole. According to the non-rigid shaft combined machining device, the microcosmic uneven degree height can be reduced, the product surfaces can be enhanced, the dispersive range of product dimension and geometrical shape tolerances is reduced, the surface residual stress and microcosmic structure variation is stable, and the machined surface precision and the production efficiency are improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a non-rigid shaft combined processing device. Background technique [0002] The non-rigid shaft is a common part in the machine, such as the piston rod of the hydraulic cylinder of the tractor in the agricultural machinery, and the joystick in the textile machinery is one of them. Frames, heel holders, double-wheel knives, etc. When the precision requirements of non-rigid shaft parts are high (IT7-IT8, Ra = 0.32mm), the traditional processing method cannot meet the requirements, the geometric shape deviation of the product is large, the processing accuracy cannot be required, the production efficiency is low, time-consuming and laborious, and The workpiece has high requirements on the processing equipment, which increases the production cost. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method that can reduce th...
