Problems solved by technology

Due to various reasons such as the manufacturing deviation of the cassette shell and the tightening device, the manufacturing deviation and installation deviation of the screw and the iron buckle, and the positioning deviation of the turntable, it is easy to locate the three parts of the cassette housing, the screw and the iron buckle during the automatic assembly process of the cassette. Deviations lead to screw jamming or over-tightening during the assembly process of the cassette, which affects the use of the cassette product, and the screwing process is seriously interrupted, affecting the normal assembly and production of the cassette

Abstract

The invention relates to the technical field of the switch dark box, especially to a method for controlling a screw driving offset of a switch dark box. A torque transducer arranged between a rotary table and a motor is measured to obtain an nth torque offset value en and a change rate delta en of the nth torque offset; and then according to the nth torque offset value en and the change rate delta en of the nth torque offset, specific regulation is carried out. According to the method provided by the invention, the offset during screw driving is small.

Description

technical field [0001] The invention relates to the technical field of switch cassettes, in particular to a method for controlling screwing deviation of a switch cassette. Background technique [0002] At present, the switch cassettes on the market generally include three parts: the shell, the screw and the iron buckle. The assembly is mostly manual assembly. There are a lot of simple and repetitive tasks in the product assembly. The poor environment leads to a large turnover of personnel, which further causes the instability of product quality. However, as labor costs continue to rise and the employment situation becomes increasingly severe, it will be an inevitable trend for the development of the cassette manufacturing industry in the future to adopt automated assembly technology to improve the production efficiency and product quality of cassettes, and effectively solve the problems of labor shortages faced by enterprises. . [0003] The prior art screwing machine comp...
