Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1 to Figure 3 Shown, a kind of torsion spring fatigue testing machine, this testing machine comprises main body 11, motor 12, transmission mechanism 13, torsion spring fixture, lifting table 16 and rotary handle 15, and this main body 11 provides an installation foundation, motor 12, lifting table 16 and the torsion spring fixture are respectively fixedly connected to the main body 11; the motor 12 provides the driving force of the test, and the transmission mechanism 13 transmits the driving force. The moving direction of the lifting platform 16 is perpendicular to the swing plane of the torsion spring base 142 , and the torsion spring top base 141 is fixed on the lifting platform 16 . The torsion spring top seat 141 is arranged on the lifting platform 16, so that the distance between the torsion spring top seat 141 and th...

Abstract

The invention provides a torsional spring fatigue tester, which includes a main body, a motor, a transmission mechanism, a torsional spring fixture, a lifting platform and a rotating handle. The motor and the lifting platform are fixed and connected with the main body respectively; the torsional spring fixture includes a torsional spring top seat and a torsional spring bottom seat, which are arranged face to face rightly; the torsional spring bottom seat is also fixed and connected with the main body; the torsional spring bottom seat is driven to swing by the motor through the transmission mechanism; the lifting platform is driven to move linearly by the rotating handle; the moving direction of the lifting platform is perpendicular to the swinging plane of the torsional spring bottom seat; the torsional spring top seat is fixed and connected with the lifting platform; and the transmission mechanism includes a crank and rocker mechanism. The invention has the benefits as follows: a torsional spring in springs is subjected to a fatigue test, and the cyclic stress resistance of the special torsional spring under special work conditions can be simulated and determined. The crank and rocker mechanism drives a fixture bottom seat to swing, the simple structure can provide the cyclic swinging test stress, and meanwhile the length of a connecting rod can be adjusted according to special work conditions, so that the swinging angle of the torsional spring can be changed.

Description

technical field [0001] The invention relates to the technical field of spring testing, in particular to a torsion spring fatigue testing machine. Background technique [0002] Springs are widely used in automobiles, chemicals, abrasive tools and other fields, and their performance directly affects the use characteristics of the machines they belong to. The performance of the spring is mainly determined by the following parameters: the diameter of the spring steel wire, the diameter of the spring, the pitch of the spring, the material of the spring, etc. The strength of the spring material itself has basically nothing to do with the working performance of the spring. [0003] During the use of the spring, it is subjected to random loads and undergoes more than tens of millions of cyclic stress changes and finally fails. The failure of the spring is generally fatigue damage, so the research on the spring fatigue damage test is very important. The existing spring testing equ...
