Cylindrical helical compression spring performance test fixing support

Abstract

A cylindrical helical compression spring performance test fixing support provided by the invention comprises an upper fixing support and a lower fixing support which are independent, wherein the upper fixing support comprises a first fixing plate, a first limiting base stand, a first axis tube and an upper blocking tube, the lower fixing support comprises a second fixing plate, a second limiting base stand, a second axis tube and a lower blocking tube, and mounting holes are respectively formed in the first fixing plate and the second fixing plate. According to the cylindrical helical compression spring performance test fixing support, the upper and lower fixing supports can be reliably and effectively fastened with test equipment through bolts, so that the upper and lower supports are ensured not to loosen or displace in the test working process; the first limiting base stand and the second limiting base stand can effectively limit the displacement or dislocation of a spring in the test process; and when the first axis tube and the second axis tube are installed with detection equipment, the coaxiality of the upper fixing support and the lower fixing support can be adjusted, and it is guaranteed that the axial perpendicularity deviation of the spring caused by the detection equipment is avoided before the spring is tested and installed.

Description

technical field [0001] The invention relates to the field of spring performance test devices, in particular to a cylindrical helical compression spring performance test fixed support. Background technique [0002] With the widespread use of spring vibration isolators in vibration reduction and shock resistance, the use of helical compression springs increases accordingly. Generally, spring vibration isolators use metal cylindrical helical compression springs. [0003] While the metal cylindrical helical compression spring is widely used, the quality of the spring is required to be reliably guaranteed. Facing the huge spring performance test and detection, a series of test requirements are put forward for the control of the spring test conditions. Therefore, the use of reliable spring test-assisted test supports can reasonably and effectively improve the accuracy of test data, which is the current test requirement. [0004] The existing spring performance test mainly has the...

AI Technical Summary

Problems solved by technology

[0004] The existing spring performance test mainly has the following problems: first, during the existing spring performance test, the spring is generally placed directly on the testing equipment workbench for various tests, because the long-term reciprocating test will cause the spring test process to produce different degrees Offset, which will lead to large discrete test data, and excessive offset will cause damage to the spring reciprocating test process, and it is impossible to obtain accurate and reliable test data

Second, in the process of spring lateral large-scale deviation test, when the lateral force of the spring will be greater than the friction force between the spring and the test bench, if the spring is not fixed up and down, the spring will fall over, which will bring great harm to the test equipment or test personnel. harm, and the spring steel wire is generally cylindrical and cannot form an effective fixation with the test bench
