Abstract

The invention provides a gasket elasticity test tooling. The gasket elasticity test tooling comprises an upper clamping block and a lower clamping block which are used for clamping a compressing to-be-measured gasket, wherein facing ends of the two clamping blocks are correspondingly provided with an upper positioning plane and a lower positioning plane. The gasket elasticity test tooling also comprises a supporting base; the lower clamping block is arranged on the supporting base through a supporting adjusting mechanism along the vertical direction in an adjustable supporting mode; the supporting adjusting mechanism also comprises a driving portion which is in transmission connection with the lower clamping block to drive the lower clamping block to move in the vertical direction; a supporting positioning platform is arranged on the side of the lower clamping block on the supporting base; the supporting positioning platform is provided with a supporting positioning plane which is used for being in contact top press fit with the upper positioning plane; the height difference between the supporting positioning plane and the lower positioning plane in the vertical direction is equal to the set test thickness of the to-be-measured gasket. The gasket elasticity test tooling does not need to satisfy test requirements of gaskets in different sizes through positioning gasket blocks in different thicknesses in the prior art, is low in manufacture cost and rapid and convenient to test.

Description

technical field [0001] The invention relates to a washer elasticity test tool. Background technique [0002] Washers in the field of mechanical fasteners include elastic washers, spring washers and lock washers, and lock washers can be divided into tapered lock washers, internal tooth lock washers and external tooth lock washers. For the above-mentioned gaskets that can rely on their own elasticity to play a locking and fastening role, the elasticity of the gasket itself is a major criterion for measuring its performance. National standards such as GB94.2 stipulate the elasticity test methods for such gaskets. , it is required to place the gasket to be tested in two parallel planes for compression, and compress the gasket to the set test thickness (for example, for internal tooth lock washers and external tooth lock washers, the set test thickness is S+0.12mm , where S is the thickness of the washer body), then loosen and then measure the height of the washer.
