A pre-positioning bushing for solid lubricating gasket assembly

Abstract

The invention discloses a pre-positioning liner used for assembling solid lubricating gaskets, and relates to the technical field of solid lubricating gasket assembly, comprising a pre-positioning liner body, a circular baffle and fins, the pre-positioning liner The core is designed in a cylindrical shape, and at the same time, fins are fixedly installed on the outside of the pre-positioning core body, and a circular baffle is fixedly installed on one end of the pre-positioning core body, and the pre-positioning core body is clamped by the fins On the inner wall of the solid lubricating gasket, it will not slide off the inner wall of the solid lubricating gasket due to the self-weight of the pre-positioning core body, thereby realizing the pre-fixation of the solid lubricating gasket, making it concentric with the light hole of the frame, During the assembly process of the module, when the connecting screw on the module enters the gasket, the lining core will fall off easily by relying on the weight of the module. At the same time, the material of the pre-positioning lining core is polytetrafluoroethylene, which has proper elasticity and hardness, and can not only lubricate the solid The gasket is reliably pre-positioned without compromising the surface quality of the gasket.

Description

technical field [0001] The invention relates to the technical field of solid lubricating gasket assembly, in particular to a pre-positioning bushing used for solid lubricating gasket assembly. Background technique [0002] The antenna panel assembly is to integrate the active integrated module with the antenna carbon fiber frame. 10 screws have been installed on the module, the frame is placed on the tooling horizontally, the module is assembled from the top of the frame downwards, and a solid lubricating gasket is required between the module and the frame. The process flow is: 1) Place solid lubricating gaskets above the 10 light holes of the frame lugs; 2) Install the module into the frame, and insert the 10 screws on the module into the corresponding 10 gaskets and light holes on the frame lugs. In the hole, the solid lubricating gasket must not slip out or fall; 3) 10 screws are installed with ordinary flat washers, ordinary spring washers and nuts, and then tighten the...

AI Technical Summary

Problems solved by technology

When installing a single active integrated module into the antenna frame, it is necessary to accurately and reliably pre-position 10 solid lubricating gaskets so that they do not deviate from the center of the optical hole, slip out or fall during the assembly process to ensure the quality of the gaskets. Ensure that the module assembly is foolproof, but at present, the solid lubricating gasket is assembled between the active integrated module and the antenna frame lug, and the conventional method is prone to eccentricity, slipping, and low efficiency, which affects product reliability and surface quality of the gasket
