Problems solved by technology

Since the coil spring itself is a part that has been in service for a long time, the test time is often very long. The traditional test method is to manually install the coil spring on the testing machine and then start the testing machine to start the test.
Not only does this process take a long time, but the replacement of the coil spring requires manual operation, resulting in inefficiency. In addition, the coil spring may lose its elastic deformation ability before it breaks, resulting in inaccurate measurement results.

Abstract

The invention discloses an apparatus of automatically detecting a coil spring life. The apparatus comprises a rack. The apparatus is characterized in that the rack is provided with a fixing mechanism, a detection mechanism and a material moving mechanism. The apparatus has the advantages that through a plurality of sliding tables, automatic material taking and automatic emptying functions are realized so that manual operation is replaced and efficiency is increased; a torsion sensor is used to repeatedly measure torsion changes of a coil spring during contraction and elongation processes so as to determine a service life, and a coil spring fracture mode is replaced so that a measurement result is effective and accurate; continuous measurement of the plurality of coil springs can be realized, personnel intervention is not needed during a whole process, the structure is ingenious, and operation and maintenance are convenient.

Description

technical field [0001] The invention relates to the field of testing plane scroll springs, in particular to an instrument capable of testing the life of plane scroll springs. Background technique [0002] The coil spring, also known as the clockwork spring, is a spring with a helical wire in a plane, a spring made of a special material wound into a plane spiral. One end of the spring is fixed, and the other end is subjected to bending moment after torque is applied to the material, resulting in bending elastic deformation, so the spring is twisted in its own plane. The size of the deformation angle is proportional to the torque. It has high torque and multi-angle torsional moment, so it is used in mechanisms that perform work for a long time. It has the characteristics of not being fatigued, and its application is similar to that of a torsion spring. The main performance indicators of coil springs are maximum torque, minimum torque and service life. [0003] The method of ...
