Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as Figure 1-5As shown, the temperature-controlled multi-phase horizontal spring fatigue testing machine includes a working platform 1 and a driving mechanism. The working platform 1 is provided with a spring horizontal installation mechanism for installing the spring under test and making the spring under test in a horizontal state. 2. There are several spring horizontal installation mechanisms 2 and they are evenly distributed in the circumferential direction. The working platform 1 is provided with a transmission mechanism 3 connected to the drive mechanism, and the transmission mechanism 3 is arranged on each spring horizontal installation mechanism 2. The center of the formed circle, and when the driving mechanism drives the transmission mechanism 3 to move, the transmission mechanism 3 can drive the measured springs ...

Abstract

The invention provides a temperature-controlled multiphase horizontal spring fatigue tester, aiming to solve the problems like uneven stress during existing spring tests. The tester comprises a workbench and a driving mechanism. A plurality of spring horizontal mounting mechanisms are arranged on the workbench and evenly distributed in the peripheral direction. A transmission mechanism connected with the driving mechanism is arranged on the workbench and at the center of a circle formed by the spring horizontal mounting mechanisms in a surrounding manner. When being driven by the driving mechanism to move, the transmission mechanism sequentially drives to-be-tested springs to axially stretch back and forth. Heating and insulating devices are arranged on the peripheries of the spring horizontal mounting mechanisms. The temperature-controlled multiphase horizontal spring fatigue tester has the advantages of simple and reasonable structure, high stability, capability of testing fatigue properties of the springs at different temperatures, high testing accuracy, high working efficiency, capability of testing a plurality of springs at the same time, high safety, wide application range, convenience in mounting of the to-be-tested springs and high automation degree.

Description

technical field [0001] The invention belongs to the technical field of springs, in particular to a temperature-controlled multi-phase horizontal spring fatigue testing machine. Background technique [0002] The spring fatigue characteristic is an important indicator of the quality of the spring. It refers to the fracture phenomenon of the spring after being squeezed and deformed. Generally, cracks will occur after the metal is deformed. It is generally small, and sometimes it can be ignored, but it is often deformed. The number of cracks will increase, and the crack gap will increase, eventually leading to spring fatigue. The spring fatigue testing device mainly performs fatigue testing on the spring by compressing or stretching the spring to obtain the fatigue characteristics of the tested spring, so that the appropriate spring can be used correctly in different applications, so the spring fatigue testing device has become And one of the necessary devices for application m...
