Problems solved by technology

[0002] The busbar direction of the expansion sleeve of the expansion flange generally has a gap, that is, on the basis of the complete rotary surface, a part is removed along the direction of the busbar by milling, pulling, wire cutting, etc., so that the expansion sleeve becomes incomplete. After tightening The expansion sleeve will produce a certain deformation, which will affect the fit of the working surface, and the processing method is more troublesome

Embodiment Construction

[0015] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0016] refer to figure 1 and figure 2 As shown, a double-cone expansion sleeve notch processing technology includes the following steps:

[0017] 1), firstly, a stress groove 5 is opened radially on the expansion sleeve 3;

[0018] 2), then put the inner sleeve with the stress groove 5 on the base 4, and place the two semicircular sleeves 2 in the holes of the expansion sleeve 3;

[0019] 3) Align the indenter 1 with the tapered surface of the semicircular sleeve 2 to force the semicircular sleeve 2 to move radially;

[0020] 4) Finally, force is applied to the expansion sleeve 3 from the inside, and as a result, the expansion sleeve 3 will break at the stress groove 5 where the stress is co...

Abstract

The invention discloses a double-conical-surface expansion sleeve notch machining technology. The technology comprises the steps that (1) firstly, a stress groove is formed in an expansion sleeve in the radial direction; 2) placing the inner sleeve with the stress groove on a base, and placing two semicircular sleeves 2 in holes of the expansion sleeve; 3) aligning a pressure head to the conical surface of the semicircular sleeve to force the semicircular sleeve to move radially; 4, finally, force is applied to the expansion sleeve from the inside, and as a result, the expansion sleeve can be broken at the stress groove where stress is concentrated, and an irregular section is formed. The method has the advantages that no material loss exists, after the expansion sleeve is tightened, the broken position can be completely embedded, the expansion sleeve is not prone to deformation, the working face is easier to guarantee, and the machining process is easier to achieve and faster.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a process for processing a gap of a double-cone expansion sleeve. Background technique [0002] The busbar direction of the expansion sleeve of the expansion flange generally has a gap, that is, on the basis of the complete rotary surface, a part is removed along the direction of the busbar by milling, pulling, wire cutting, etc., so that the expansion sleeve becomes incomplete. After tightening The expansion sleeve will produce a certain deformation, which will affect the fit of the working surface, and the processing method is more troublesome. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of material loss, and after the expansion sleeve is tightened, the fracture can be completely fitted, the expansion sleeve is not easy to deform, the working surface is easier to ensure, and the processing process is ea...
