Abstract

The invention provides a gasket elasticity test tool, which includes upper and lower clamping blocks for clamping and compressing the gasket to be tested. The opposite ends of the two clamping blocks are correspondingly provided with upper and lower positioning planes. The test tool also includes a supporting base, The lower clamping block is vertically adjustable supported by the support adjustment mechanism on the support base, and the support adjustment mechanism has a transmission connection with the lower clamping block to drive the lower clamping block to move in the vertical direction. In the driving part, a support positioning platform is provided beside the lower clamping block on the support base, and the support positioning platform has a support positioning plane for contacting and press-fitting with the upper positioning plane, and the support positioning plane and the lower positioning plane are at The height difference in the vertical direction is equal to the set test thickness of the gasket to be tested. The elastic test tool does not need to use positioning pads of different thicknesses to meet the test requirements of washers of different sizes as in the prior art, and the manufacturing cost of the tool is low, and the test is quick and convenient.

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. [0003] In ...
