Problems solved by technology

The currently widely used wind tunnel strain balance gluing fixture does not have the function of quantitative pressure. The structure and dimensions of the fixture are customized according to the structure and size of the specific balance. The gluing fixtures are not interchangeable between different balances, and the gluing fixture cannot be realized. Common to all stick wind tunnel strain balance implementations
In addition, using the existing fixture can only pressurize two components of the balance at the same time, resulting in the problem of increased workload caused by multiple disassembly and assembly

Embodiment Construction

[0029] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0030] figure 1 and figure 2 Shown is the overall layout of the quantitative pressurization system of the invention. According to the working effects of each component, the quantitative pressurization system is divided into several parts: support connection parts, radial force application parts and axial force application parts. The four main shafts connect and fix the front support base and the rear support base to form the basic frame of the entire support part. The force applying part moves freely on the main shaft, and when it reaches the designated force applying position, it is fixed by the locking device on the force applying part. Apply a constant amount of force. Depend on figure 1 It can be seen intuitively that the axial force application system and the radial force applicatio...

Abstract

The invention discloses a universal quantitative pressure application system for pasting a rod type wind tunnel strain balance. The universal quantitative pressure application system is characterizedby comprising a supporting and connecting part, radial force application parts and an axial force application part; the quantitative pressure application control is used as an idea; the stable performance of an integrated frame structure is used; the influence of the temperature on the integral deformation is fully considered in material selection; the quantitative pressure application control onall weights in the process of pasting and curing the strain balance is ensured. Through the universal pressure application system, the problem that a pressure application value cannot be quantified inthe pasting process of the rod type wind tunnel strain balance is solved; meanwhile, the problems of low universality and the insufficient one-time pressure application weight of a pasting clamp aresolved; the inconvenience caused by frequently assembling and disassembling is avoided; the pasting quality and efficiency of the rod type wind tunnel strain balance are improved; meanwhile, the production cost of the pasting clamp is reduced; the quality and the benefit of wind tunnel test are favorably improved.

Description

technical field [0001] The invention relates to the field of rod-type balances, in particular to a general-purpose rod-type wind tunnel strain balance pasting quantitative pressurization system. Background technique [0002] During the bonding process of the wind tunnel strain balance, applying quantitative pressure to the resistance strain gauge on the surface of the measuring element is an important link to ensure the balance has good performance. The currently widely used wind tunnel strain balance gluing fixture does not have the function of quantitative pressure. The structure and dimensions of the fixture are customized according to the structure and size of the specific balance. The gluing fixtures are not interchangeable between different balances, and the gluing fixture cannot be realized. Common to all stick wind tunnel strain balance implementations. In addition, using the existing fixture can only pressurize the two components of the balance at the same time, wh...
