U-shaped spring clamp elasticity test system and elasticity test method

Abstract

The invention relates to a U-shaped spring clamp elasticity test system and an elasticity test method. The U-shaped spring clamp elasticity test system comprises: a testing tool, wherein the testing tool comprises a pressing block used for applying pressure to a U-shaped clamp, a cushion block used for positioning the deformation size of the U-shaped clamp and a containing table, the containing table is provided with a transverse groove used for containing the U-shaped clamp and allowing the pressing block to be inserted and a vertical groove allowing the cushion block to be inserted into theopening of the U-shaped clamp, and the transverse groove and the vertical groove are communicated in a crossed mode; a manual pressing machine which is used for applying pressure to the pressing block; and a detection assembly which is connected to the manual pressing machine and is used for detecting the elastic force of the U-shaped clamp. The U-shaped spring clamp elasticity test system is convenient to install, easy to operate, capable of utilizing existing equipment, simple in tool, small in machining difficulty and small in investment; and when the U-shaped spring clamp elasticity test system is used for elasticity testing, the elasticity value of the U-shaped spring clamp compressed under the specified size can be rapidly tested.

Description

technical field [0001] The invention belongs to the field of testing automobile motor parts, in particular to a U-shaped spring clamp elastic force testing system and an elastic force testing method. Background technique [0002] With the continuous development of the automobile industry, the lifting and lowering of car windows has bid farewell to the era of hand cranking, which is basically driven by motors. However, the motor stator part of some car window shakers on the market also uses U-shaped spring clips to support the magnet. The fixing method of steel has relatively high requirements on the elastic force of the U-shaped spring clip. Therefore, a strict elastic force test is required before the U-shaped spring clip is put into use. [0003] At present, the elastic force of the U-shaped spring clip is verified by indirect means, such as the spring force of the U-shaped spring clip according to the pull-out force of the magnetic steel after the motor stator is assemble...

[0003] At present, the elastic force of the U-shaped spring clip is verified by indirect means, such as the spring force of the U-shaped spring clip according to the pull-out force of the magnetic steel after the motor stator is assembled, the strength of the U-shaped spring clip material, etc., but these verification methods are not It is hysteresis, and is greatly affected by the unstable factors of the material, and has the risk of bad batch
