Steel wire thread insert friction coefficient detection equipment and detection method

Abstract

The invention discloses steel wire thread insert friction coefficient detection equipment and a detection method, and relates to the technical field of steel wire thread insert detection. In order to solve the problems that how to measure the parameters of the friction coefficient of the steel wire thread insert is not met at present, and a traditional friction coefficient tester in the market is low in detection precision, large in error and incapable of meeting the measurement of workpieces of various models. The steel wire thread insert friction coefficient detection equipment comprises a rack, one side of the upper surface of the rack is fixedly connected with a translation driving mechanism through bolts, and a friction coefficient detection mechanism is installed on the side, close to a fixed case, of the upper surface of the rack. Data of the sensor are read through the controller, the friction coefficient of the steel wire thread insert is calculated according to a formula, digital display and reading are convenient and accurate, the steel pipe die sleeve and the die core are replaced according to measurement of steel wire thread inserts of different models, the production cost is greatly reduced, installation is more convenient and stable, use flexibility is improved, measurement efficiency is improved, and production efficiency is improved. And the continuity of measurement operation is ensured.

Description

technical field [0001] The invention relates to the technical field of steel wire helical sleeve detection, in particular to a detection device and method for the friction coefficient of a steel wire helical sleeve. Background technique [0002] The wire thread sleeve is evenly distributed along the length of the screw, which makes the load stress distribution uniform and is widely used in the industrial field. During the assembly and use of the wire screw insert, in order to ensure the reliable service of the wire screw insert, it is necessary to ensure that there is an appropriate tightening pre-tightening force during assembly. The size of the pre-tightening force is an important factor to ensure the connection quality of the wire screw sleeve. The tightening process of the wire screw sleeve is a process of overcoming friction. In this process, there is friction in the threaded part of the wire screw sleeve, which results in the concept of friction coefficient. . The fr...
