Abstract

The invention discloses a measuring device for a spring washer elasticity test and a measuring method of the measuring device for the spring washer elasticity test. The measuring device for the spring washer elasticity test comprises a base, a load unit, a pressure measuring unit and a height measuring unit. The load unit comprises an oil cylinder, an oil rod, a connecting sleeve and a top plate. The oil cylinder is vertically installed on the base, the connecting sleeve is installed at the top end of the oil cylinder, the top plate is installed at the top end of the connecting sleeve, a central hole is formed in the middle of the top plate, and the oil rod is vertically installed in the oil cylinder. The pressure measuring unit comprises a pressure gauge and a connecting oil pipe. The pressure gauge is installed on the base, one end of the connecting oil pipe is communicated with the pressure gauge, and the other end of the connecting oil pipe is communicated with the oil cylinder. The height measuring unit comprises a length measuring instrument, a conducting strip and an insulating block. The insulating block is inlaid into the top plate, the conducting strip is arranged in the insulating block in a built-in mode, the length measuring instrument is provided with an ejecting rod, and the length measuring instrument is installed in the central hole in the conducting strip in an inserting mode. The measuring device for the spring washer elasticity test is high in detection speed and accurate in measurement data. The invention further discloses the measuring method using the measuring device for the spring washer elasticity test.

Description

technical field [0001] The invention relates to a measuring device for a spring washer and a measuring method thereof, in particular to a measuring device and a measuring method for the elasticity test of a spring washer. Background technique [0002] Spring washer is a kind of washer widely used in load-bearing and non-load-bearing structures of general mechanical products. It is used under nuts to prevent nuts from loosening. It is characterized by low cost and easy installation, and is suitable for parts that are frequently assembled and disassembled. The national standard has requirements on the size of the spring washer, especially the free height of the spring washer after the elasticity test. The free height of the spring washer includes the free height of the initial state of the spring washer just produced and the free height of the spring washer after the test loading test. The height measurement values ​​of the two free heights are measured by measuring the height...
