Multi-station triaxial force application testing machine

Abstract

The invention relates to the technical field of machinery, in particular to a multi-station triaxial force application testing machine. The multi-station triaxial force application testing machine is characterized in that two cylinder brackets and a cylinder supporting plate are arranged on a platform, and each cylinder bracket adopts a T-type plate structure formed by vertically connecting a vertical plate on a horizontal bottom plate; the horizontal bottom plates of the two cylinder brackets are arranged on the platform respectively in an X direction and a Y direction; and the side surfaces on the upper parts of the vertical plates of the cylinder brackets arranged in the X direction and the Y direction and the upper part of the cylinder supporting plate are respectively hinged with the tail ends of cylinders in a drive mechanism to respectively form an X-direction force application mechanism, a Y-direction force application mechanism and a Z-direction force application mechanism. Compared with the prior art, the multi-station triaxial force application testing machine has the advantages that the force application mechanisms are light and can meet the rigidity requirement, so that the real train states of force application in the X direction, the Y direction and the Z direction can be guaranteed; and grooves are distributed on the platform in a shape like a Chinese character jing, so that an adjustable sample piece fixing mechanism and the force mechanisms can be set up as required to meet the requirements of tests of force application directions in multiple forms, and the test efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a multi-station three-axis force testing machine. Background technique [0002] With the development of the machinery industry and the continuous improvement of technical requirements, various stress fatigue simulation testing machines have emerged as the times require. Especially for the steering wheel in the automotive industry, generally the steering wheel needs to be subjected to force fatigue simulation tests by applying X, Y, and Z-direction pressures, where the Z-direction load is applied, that is, the loading direction of the steering wheel steering rim plane Implement positive load at 45 degrees; apply positive load in X / Y direction, even if the steering wheel rim bears tangential force. [0003] Due to design reasons, the original multi-station three-axis force-applying tester for the steering wheel of the simulation test has the following problems: 1. Because the cy...

Problems solved by technology

[0003] Due to design reasons, the original multi-station three-axis force-applying tester for the steering wheel of the simulation test has the following problems: 1. Because the cylinder of the force-applying mechanism is fixed in the form of "a groove at the front end of the cylinder", the cylinder The force exerted by the spindle on the tested steering wheel hub is a fixed linear force, which does not conform to the force state of the actual vehicle.

2. The three-axis force-applying mechanism and prototype fixing mechanism of the original testing machine are fixed, which is not flexible enough, that is, it cannot meet the actual needs of the test task, and the test efficiency is not high
