Rotating self-pulling type framework gasket

Abstract

The invention discloses a rotating self-puling type framework gasket which comprises a framework appearance piece, a rod and a positioning block. The framework appearance piece is arranged at one endof the rod, and the other end of the rod is sleeved with a nut. The positioning block is installed at the body portion of the rod in a pre-compressing and limiting manner. The positioning block comprises an upper plate, a vertical plate and a lower plate. One side of the upper portion of the lower plate is provided with the upper plate through the vertical plate, and a rod passing hole is formed in the vertical plate. Installation lugs are arranged on the front side and the rear side of the lower portion of the lower plate in an outwards-extending manner. Installation holes are formed in the installation lugs, and a pin hole is formed in the rod in the radial direction. A cylindrical pin is arranged in the pin hole. Longitudinal grooves matched with the cylindrical pin in a limiting mannerare formed in the sides, close to the framework appearance piece, of the upper plate and the lower plate. By means of the rotating self-pulling type framework gasket, the appearance of a clamping plate does not need to be damaged, the rotating self-puling type framework gasket is conveniently used at the appearance position of a product with a protruding rivet head, the product assembling qualityand the product assembling efficiency are improved, the manufacturing period of the product is shortened, and therefore the production operation efficiency is effectively improved.

Description

technical field [0001] The invention relates to a rotary self-pull type skeleton gasket. Background technique [0002] In the aircraft assembly process, the positioning pad is also called the skeleton gasket. The skeleton gasket is used to simulate the thickness of the aircraft skin, so that the pallet can not only assemble the product skeleton but also complete the product skin 100 riveting assembly after the assembly is completed. The existing frame spacer refers to [Aviation Industry Standard] HB 611-1989 positioning plate, its front view is as follows figure 2 As shown, when using figure 1 As shown; before assembling the skin 100, it is necessary to simulate the thickness of the skin 100 at the backing plate, install the skeleton gasket on the clamping plate 200, and then tighten the wing nuts to adjust to the correct position; when the skin 100 is installed , it is necessary to loosen the wing nut. In order to prevent the skeleton gasket from interfering with the pro...

AI Technical Summary

Problems solved by technology

[0004] 1. The steps are cumbersome, and the wing nut needs to be loosened and tightened repeatedly, which wastes labor costs, reduces the service life of the skeleton gasket, and reduces the assembly accuracy;

[0005] 2. Opening the exit groove of the skeleton gasket on the pallet will destroy the consistency of the pallet, reduce the product profile that the pallet can be positioned on, and make the profile of the pallet incomplete. If there is a protruding rivet head Due to the limited exit space, in order to prevent the gasket from interfering with the rivet head, the exit groove on the pallet needs to be deepened before it can be used, which increases the damage to the pallet and increases the Difficult to process and easy to cause card board damage

[0006] 3. If a round-head rivet is used at the joint of the aircraft skin, that is, when the rivet head protrudes from the skin shape, it will be inconvenient or impossible to use the skeleton gasket in this form.
