Pull rod assembly assembling and detecting integrated device

Abstract

The invention provides a pull rod assembly assembling and detecting integrated device. The pull rod assembly assembling and detecting integrated device is characterized in that a fixed mandrel base and a movable mandrel base are slidably arranged on a linear guide rail body, a fixed mandrel is fixed on the fixed mandrel base; and a micro linear sliding block and the movable mandrel base are relatively fixed in the horizontal direction; a sliding groove is formed in the upper surface of the micro linear sliding block, one sliding block is arranged in the sliding groove in a matched and embeddedmode, and the sliding block is fixed to the lower surface of a movable mandrel; and inner holes of rod end oscillating bearings arranged in rod end bodies at the two ends of a pull rod assembly sleeve the fixed mandrel and the movable mandrel in a matched mode correspondingly, two rod end body cover sleeves cover the two rod end oscillating bearings respectively, and the two rod end body cover sleeves press the two ends of rod end body connecting rods at the two ends correspondingly and are connected with the rod end bodies at the two ends through threads correspondingly. The pull rod assembly assembling and detecting tool is high in adaptability, high in assembling efficiency and high in percent of pass.

Description

technical field [0001] The invention relates to an assembly and testing tool for aerospace tie rod products. Background technique [0002] With the development of aviation technology, people have higher and higher requirements for the performance of aircraft components. Aerospace tie rods are an important part of aircraft components. It has the characteristics of many interface sizes, different center lengths, and high center distance accuracy (±0.1mm). At the same time, the planes of the assembled rod end bodies 5 (fork ears) at both ends are required to be parallel. more stringent requirements. [0003] However, the traditional tie rod assembly method needs to thread the rod end body 5 (fork ear) at one end to the connecting rod 6, manually screw it in and lock it, then connect the other end by the same means, and pass the vernier caliper (three Coordinates) to measure the center distance; this method can easily lead to: [0004] (1) The end faces at both ends are not ...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional tie rod assembly method needs to thread the rod end body 5 (fork ear) at one end to the connecting rod 6, manually screw it in and lock it, then connect the other end by the same means, and pass the vernier caliper (three Coordinates) to measure the center distance; this method can easily lead to:

[0004] (1) The end faces at both ends are not parallel, and manual adjustment cannot control the planes at both ends; after the tie rod is assembled, the nut needs to be locked, and the two planes will not be parallel during the locking process;

[0005] (2) The tolerance requirements for the center distance of the tie rod assembly are relatively strict, and the center distance dimension is measured after assembly, and the pass rate of the dimension is low;

[0006] (3) When the pull rod is assembled, one end is screwed in and then locked, and then the other end is locked, so the assembly efficiency is low;

[0007] (4) The amount of screwing in at both ends cannot be controlled, and it is easy to cause one end to be screwed in more or less than the other end.
