Axial force static torsion composite device

Abstract

The invention discloses an axial force static-torsion composite device, comprising an axial force testing device and a static torque testing device, and a housing structure integrating the axial force testing device and the static torque testing device into a whole. The beneficial effects are as follows: the technical solution of the present application combines the structure for testing the axial force and the static torque into an integral outer frame, so as to realize the integrity of the device, and the installation and testing are convenient and quick; When a non-vertical force acts, the data of the load sensor is linearly distorted, and when there is a non-rotational force on the inner sleeve of the static torque sensor, the data of the static torque sensor is linearly distorted, so as to ensure the correctness of the linearity of the data; there is only one cable output for the whole device. It reflects the integrity of the device.

Description

technical field [0001] The invention relates to a test equipment, in particular to a test device for axial force and thread torque in the friction coefficient test of threaded fasteners. Background technique [0002] Threaded fasteners are mechanical components used in almost all mechanical equipment. The performance of threaded fasteners is one of the most important technologies that affect the reliability of mechanical connection technology. Over-tightening, missing-tightening and under-tightening occur after the occurrence of solids. To ensure that each threaded fastener can work normally after tightening, it is necessary to test the static torque (hereinafter referred to as static torque) and axial force of the threaded fastener. In the traditional test method, only one performance test can be completed when using a testing machine for testing, such as a separate static torsion test or a separate axial force test. The structure of the equipment is complicated and the ope...

Problems solved by technology

In the traditional test method, only one performance test can be completed alone when using a testing machine for testing, such as a separate static torsion test or a separate axial force test. The equipment structure is complicated and the operating procedures are cumbersome; When there is a non-perpendicular force acting on the bearing surface of the load sensor, the linearity of the load sensor data will be distorted; similarly, when the static torque sensor tests static torsion, and when there is a non-rotational force on the inner sleeve of the static torque sensor, the linearity of the static torque sensor data will be distorted. distortion, the existing equipment cannot effectively guarantee the correctness of the test data linearity of the load sensor and the static torque sensor
