Method for producing workpiece

Abstract

The workpiece manufacture process includes the following steps: 1) forming one blank, drilling holes, threading, chamfering, etc.; 2) coaxially cutting the blank to form coaxially fitted inner part and outer part; 3) milling the inner part and outer part separately and heat treatment to fix the contour, holes and threads of both inner part and outer part; 4) combining the inner part and the outer part and forming several pairs of guide pin holes parallel to the axis in the adjoining parts of the inner part and the outer part; 5) eliminating unneeded parts; and 6) combining the inner part and the outer part to finish the machining. The said process can raise the coaxiality of coaxial workpiece and lower workpiece manufacture cost.

Description

【Technical field】 [0001] The invention relates to a workpiece, in particular to a method for manufacturing a coaxial workpiece. 【Background technique】 [0002] Please refer to FIG. 1 , the coupling device 2 generally used to connect the transmission device and the driven part mainly includes two couplings 21 and a set of working shafts 22 connected between the couplings 21 . The couplings 21 respectively include an inner part 211 and an outer part 212 that fit together, and several guide posts 213 that pass through the adjacent parts of the inner part 211 and the outer part 212 . In this way, the inner part 211 and the outer part 212 can use the locking effect formed by the guide post 213 to make the inner part 211 and the outer part 212 form a linkage relationship, and use the guide post 213 to enhance the transmission function. [0003] At present, when the industry manufactures the shaft coupling 21, it first makes the inner part 211 and the outer part 212 respectively, ...

Problems solved by technology

[0003] At present, when the industry manufactures the shaft coupling 21, it first makes the inner part 211 and the outer part 212 respectively, and then combines the inner part 211 and the outer part 212 to form, and the shaft coupling 2 and the outer part 212 When assembling the transmission shaft (not shown), it is necessary to consider whether its axis is on the same axis, so as to ensure the smoothness of rotation, the service life of the coupling device 2, and the smooth transmission of the driven part (not shown) Therefore, in the case where the inner part 211 and the outer part 212 are manufactured separately, there are often defects such as the inability to control the processing precision and the large concentricity error value, resulting in difficult processing and high manufacturing costs.
