Flexible test clamp and application method

Abstract

The invention provides a flexible test clamp and an application method and belongs to the technical field of strength and rigidity test loading of threaded connection and structural parts. The flexible test clamp can be adaptive to mounting angles and mounting manners of different test pieces and the accuracy of testing data can be ensured. The test clamp has good mounting manufacturability and is simple and convenient to use; a test period is shortened and the test efficiency is improved. A design concept that traditional special test clamps have a one to one correspondence direction is changed so that a large amount of time is saved in view of all aspects of a test, the design cost of the clamp is reduced and the problems of design defects, poor mounting manufacturability and the like are avoided; the work of big data can be planned as a whole and a test sequence is reasonable arranged, so that the manufacturing period of the test clamp is saved and the problem of managing a lot of test clamps is avoided. According to the test clamp provided by the invention, the problems of changes and the like are considered; a connector is designed so that only the connector needs to be replaced and changed even if the test pieces are changed temporarily, and furthermore, the current situation of remanufacturing the test clamp is avoided.

Description

technical field [0001] The invention relates to a flexible test fixture and a use method thereof, and belongs to the technical field of thread connection and strength and stiffness test loading of structural parts. Background technique [0002] At present, the unloading of aircraft parts requires special tooling and slings to complete, and the connection methods are mostly hooks, rings and threaded connections. In order to ensure the safety of aircraft parts, the tooling spreader must be safe and reliable. At the beginning of the design, a factor of 2 to 3 times will be reserved, but theory and practice must be combined to ensure the safety and reliability of the tooling spreader, and there are often complicated It is difficult to use computer software analysis or pure theory to realize the structure of the structure, and only the estimated value or the trend of the load can be obtained, so the practical stiffness and strength test is an indispensable link. [0003] Due to ...

AI Technical Summary

Problems solved by technology

[0004] After the design, due to the large number of spreaders and the huge special test fixtures, the maintenance and management of fixtures takes up a lot of time, space, and a lot of manpower. During the test, each spreader needs to be tested one by one. , It also takes a lot of resources to find, transport and install the fixture, and when the lifting fixture has design defects, once the tooling and lifting fixture changes its shape slightly, the special fixture can only be scrapped and it is difficult to modify
