[0002] The disc ring support is a disc ring structure, with upper and lower support surfaces, and a through hole in the middle. Some small holes are distributed on the upper and lower support surfaces. The upper and lower small holes are not concentric. It is required to press the bushing on these small holes And the shoulder of the installed bush is on the inner side of the supporting surface, so it is impossible to use the traditional bush pressing tool to realize the installation of the shoulder bush on the upper and lower supporting surfaces, so a set of tooling is designed to complete the shoulder lining Set of installation

Embodiment Construction
[0034] Below we come in conjunction with accompanying drawing and the present invention is made further description:
[0035] A set of tooling for the temperature difference assembly of the bushing on the disc ring support is designed, which is characterized in that it includes: a support 1 for force transmission and a guide column 2 for guidance. The support 1 that plays the role of force transmission is an integral structure, the upper part is the force bearing plate for the press to apply pressure, the middle part is the avoidance groove, and the lower structure has a lower limit, above the lower limit, there is a stepped groove to guide Column 2 has an interference fit relationship with the small round end of the stepped groove, and a clearance fit relationship with the inner hole of the bush 3, and the shoulder of the bush 3 has a clearance fit with the large round end of the stepped groove, and the bushing is press-fitted 3, the bushing 3 is placed on the guide column 2 ...

The invention belongs to the field of composite tools, and particularly relates to a tool for press fitting of a lining on a non-coaxial hole of a supporting piece and a mounting method. The tool comprises a support playing a role in force transmission and a guide column playing a role in guiding, the support is of an integral structure, the upper part is a force bearing plate for pressure applied by a press machine, the middle part is an avoiding groove, the lower part structure has a lower limit, a step-shaped groove is formed above the lower limit, and the guide column is in interference fit with the small round end of the step-shaped groove. The guide column is in clearance fit with the inner hole of the lining, the convex shoulder of the lining is in clearance fit with the large round end of the step-shaped groove, when the lining is pressed, the lining is arranged on the guide column in a sleeving mode, pressing of the lining is achieved, and the maximum size of the lower bottom face of the guide column matched with the support and the maximum size of the lower bottom face of the support do not make contact with a working platform in the assembling process. The tool has the advantages of being simple in structure, convenient to operate and store and the like, the working efficiency is effectively improved, and the process requirement that temperature difference assembly is completed within 20s is met.
Description
technical field [0001] The invention belongs to the field of composite tooling, in particular to a tool and an installation method for press-fitting a bush on a non-coaxial hole of a support. Background technique [0002] The disc ring support is a disc ring structure, with upper and lower support surfaces, and a through hole in the middle. Some small holes are distributed on the upper and lower support surfaces. The upper and lower small holes are not concentric. It is required to press the bushing on these small holes And the shoulder of the installed bush is on the inner side of the supporting surface, so it is impossible to use the traditional bush pressing tool to realize the installation of the shoulder bush on the upper and lower supporting surfaces, so a set of tooling is designed to complete the shoulder lining set of installation. The device is composed of a support for force transmission and a guide column for guidance. The relationship between the guide column a...
