When the shell cover assembly and the rear axle shell assembly are subjected to press fitting, the shell cover assembly is arranged on one side of the positioning seat, the arc face on the outer side of the shell cover assembly is supported by the arc-shaped supporting face on the positioning clamping jaw, meanwhile, a positioning pin on the positioning seat extends into a positioning hole in the shell cover assembly to position the shell cover assembly, and when the shell cover assembly and the rear axle shell assembly are subjected to annular welding, the shell cover assembly is clamped by the arc-shaped supporting face on the positioning clamping jaw. And the shell cover assembly is stably pressed on one side of the rear axle shell assembly.

Description

Technical Field

[0001] The utility model relates to the field of mechanical processing equipment, in particular to a press-fitting tool for a housing cover assembly and a rear axle housing assembly. Background Art

[0002] During assembly, the shell cover assembly on the rear axle housing assembly is mainly fixed by welding. During welding, the rear axle housing assembly has very high requirements for the assembly holes of the shell cover assembly, including not only the upper and lower position requirements, but also the angle requirements. Some ordinary tooling structures cannot meet the positioning requirements of the shell cover assembly. Utility Model Content

[0003] The purpose of the utility model is to solve the defects of the prior art and provide a press-fitting tool for a housing cover assembly and a rear axle housing assembly.

[0004] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0005] A press-fitting tool for a housing cover assembly and a rear axle housing assembly comprises a positioning seat, a plurality of positioning claws arranged on the positioning seat, the ends of the positioning claws are provided with arc-shaped supporting surfaces; and a positioning pin is provided on the positioning seat.

[0006] Furthermore, the positioning seat supports a shell cover assembly, and the shell cover assembly is supported and positioned by a plurality of positioning claws.

[0007] Furthermore, the arc surface on the outer side of the shell cover assembly is supported by the arc-shaped supporting surface on the positioning claw.

[0008] Furthermore, the positioning pin can extend into the positioning hole on the shell cover assembly to position the shell cover assembly on the positioning seat.

[0009] Furthermore, the number of the positioning claws is three or more.

[0010] Furthermore, the positioning claw is fixed to the positioning seat by means of bolts.

[0011] The beneficial effects of the present invention are as follows: when the shell cover assembly and the rear axle housing assembly are press-fitted, the shell cover assembly is arranged on one side of the positioning seat, and the arc surface on the outer side of the shell cover assembly is supported by the arc-shaped supporting surface on the positioning claw. At the same time, the positioning pin on the positioning seat extends into the positioning hole on the shell cover assembly to position the shell cover assembly. When the shell cover assembly and the rear axle housing assembly are ring-welded, the shell cover assembly is press-fitted stably on one side of the rear axle housing assembly.

[0015] Reference Figures 1 to 3 A press-fitting tool for a shell cover assembly and a rear axle shell assembly includes a positioning seat 1, a plurality of positioning claws 2 arranged on the positioning seat 1, and an arc-shaped supporting surface 3 is provided at the end of the positioning claw 2; a positioning pin 4 is provided on the positioning seat 1.

[0016] The housing cover assembly 5 is supported on the positioning seat 2 , and the housing cover assembly 5 is supported and positioned by a plurality of positioning claws 2 . The outer arc surface of the housing cover assembly 5 is supported by the arc-shaped supporting surface 3 on the positioning claws 2 .

[0017] Furthermore, the positioning pin 4 can extend into the positioning hole on the shell cover assembly 5 to position the shell cover assembly 5 on the positioning seat 1 .

[0018] In this embodiment, the number of the positioning claws 2 is three or more, and the positioning claws 2 are fixed to the positioning seat 1 by bolts.

[0019] When the shell cover assembly 5 and the rear axle housing assembly are press-fitted, the shell cover assembly 5 is arranged on one side of the positioning seat 1, and the outer arc surface of the shell cover assembly 5 is supported by the arc-shaped supporting surface 3 on the positioning claw 2. At the same time, the positioning pin 4 on the positioning seat 1 extends into the positioning hole on the shell cover assembly 5 to position the shell cover assembly 5. When the shell cover assembly 5 and the rear axle housing assembly are ring-welded, the shell cover assembly is press-fitted and stabilized on one side of the rear axle housing assembly.
