Pre-positioning lining core for assembling solid lubricating gasket

Abstract

The invention discloses a pre-positioning lining core for assembling a solid lubricating gasket, and relates to the technical field of assembling of solid lubricating gaskets. The pre-positioning lining core comprises a pre-positioning lining core body, a circular baffle and fins, wherein the pre-positioning lining core is designed to be cylindrical, meanwhile, the fins are fixedly mounted on theouter side of the pre-positioning lining core, the round baffle is fixedly mounted at the end part of one side of the pre-positioning lining core, the pre-positioning lining core body is clamped on the inner wall of the solid lubricating gasket through the fins, so that the pre-positioning lining core body cannot slide off from the inner wall of the solid lubricating gasket due to the self weightof the pre-positioning lining core body, and the pre-fixing of the solid lubricating gasket is realized, so that the solid lubricating gasket is in concentric with an unthreaded hole of a frame; and during the assembly process of a module, when a connecting screw on the module enters the gasket, the lining core falls off easily by means of the weight of the module, and meanwhile, the pre-positioning lining core is made of polytetrafluoroethylene which is proper in elasticity and hardness, so that the solid lubricating gasket can be reliably pre-positioned, and the surface quality of the gasketis not influenced.

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
