Embodiment

[0030] see Figure 1-5 , this implementation shows a manufacturing method with three relative angle eccentric shafts, including the following steps:

[0031] 1) Carry out the excircle cutting of the shaft part a101, the shaft part b102, the shaft part c103, the shaft part d104 and the shaft part e105 of the concentric part;

[0032] 2) Machining the shaft portion a101, the shaft portion b102, and the keyway 106 on the shaft portion c103;

[0033] 3) Prepare a fixture a2, which includes a cylindrical body a21 concentric with the eccentric shaft part 107, a device groove a22 provided on the cylindrical body a21 and matched with the shaft part a101;

[0034] 4) After the shaft part a101 and the shaft part b102 are installed on the clamp a2, the cutting process of the eccentric shaft part 107 is performed after clamping the clamp a2;

[0035] 5) Prepare the jig b3, the jig b3 includes a cylindrical body b31 concentric with the eccentric shaft part 107, a device groove b32 opened...

Abstract

The invention provides a manufacture method of an eccentric shaft with three relative angles. The method includes the following steps: performing cylindrical cutting of a shaft portion a, a shaft portion b, a shaft portion c, a shaft portion d and a shaft portion e of the concentric portion; machining key slots in the shaft portion a, the shaft portion b and the shaft portion c; manufacturing a clamp a which comprises a cylindrical body a concentric with an eccentric shaft portion and a mounting slot a formed in the cylindrical body a and matched with the shaft portion a; after installing the shaft portion a and the shaft portion b to the clamp a, performing cutting machining on the eccentric shaft portion after clamping the clamp a; manufacturing a clamp b which comprises a cylindrical body b concentric with the eccentric shaft portion and a mounting slot b formed in the cylindrical body b and matched with the shaft portion a, and arranging the cylindrical body b as a clamping plane; after arranging the shaft portion a and the shaft portion b to the clamp b, machining the machining face on the eccentric shaft after clamping the clamp b. Through the method, manufacture efficiency and manufacture precision of the eccentric shaft with three relative angles can be assured.

Description

technical field [0001] The present invention relates to machining technology, specifically, it shows a manufacturing method with three eccentric shafts with relative angles. Background technique [0002] In the operating mechanism, an eccentric shaft with a specific angle is needed between the cam pair and the spring energy storage indication to realize. There are mutual angular constraints between the keyway, milling plane and eccentric position on this shaft, which are difficult to machine. [0003] Such as figure 1 The eccentric shaft 100 is shown with three relative angles, having concentric shaft portions a101, b102, and c103, d104, e105, on a101, b102, and c103 Corresponding key grooves 106 are provided in each, and an eccentric shaft portion 107 is provided outside the shaft portion e105 , and a processed surface is provided on the eccentric shaft portion 107 . [0004] The current processing method is as follows: first turn the concentric and eccentric parts, then...
