Example Embodiment

[0037] Refer to figure 2 The preferred embodiment of the method for manufacturing a workpiece of the present invention includes the following steps:

[0038] Step 1: Form a prototype block, refer to image 3 , Figure 4 The forming method can be a cylindrical material 3 by turning processing to form a rough blank 3’, and then milling the rough blank 3’ to form such Figure 5 The prototype block 4 shown, or directly by casting or forging, is formed as Figure 5 Prototype block 4 shown. The prototype block 4 has a first ring wall 41 and a second ring wall 42 surrounding an axis X and defining a small hole section 401 and a large hole section 402, and is formed on an inner surface of the first ring wall 41 And roughly a C-shaped groove 45. The diameter width of the first ring wall 41 is larger than that of the second ring wall 42. Refer to Figure 6 , And then perform drilling, tapping, chamfering and other processing procedures on the prototype block 4.

[0039] Step 2: Refer to Fi...

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, ...
