Problems solved by technology

[0003] However, at present, screw connections on the production line are used in every device, and the screw and nut tightening devices hardly form a production line scale, which obviously affects the production efficiency of the enterprise. Therefore, this project solves the online tracking of screws. The problem of online tightening of screws and nuts at the same time solves the problem of high product efficiency and large-scale production

Embodiment Construction

[0022] The present invention will be further described below in combination with principle diagrams and specific operation examples.

[0023] Due to the small installation space of the overall device in actual use, the whole device should be compact and flexible, and can also realize the entire functional process. Therefore, the device adopts a micro servo motor to drive the inner sleeve and the outer sleeve to rotate, and the inner sleeve It consists of two parts, one is the part connected with the motor, and the other is the part for tightening the screws. The two parts are connected by a flexible steel wire rope, which is at the advanced and leading level in China.

[0024] In order to realize the adjustment of the screw and nut without additional force, a synchronous control strategy for the mutual cooperation of the two motors is designed, which can well eliminate the difference error and installation error of the motor itself, and ensure the high precision requirements of...

Abstract

The invention discloses a high-precision screw and screw nut screwing device, which has the advantages that the deformation state of a low-voltage electric appliance key component, i.e., a bimetallic strip is used as a predicating object, the randomness and the uncertainty of the heated stress deformation and the material of the bimetallic strip are subjected to predictive inference analysis, and the feedforward quantity is provided for a test system; the critical scientific problem of additional-force-free screwing of screws and screw nuts of a component at the tail end of the bimetallic strip is solved.

Description

technical field [0001] The invention relates to a tightening device, in particular to a high-precision screw and nut tightening device. Background technique [0002] With the continuous advancement of science and technology, the screw and nut tightening devices on the production lines of many factories have changed from manual to automatic, and the intelligence of production lines has been vigorously developed. Enterprises continue to improve production process requirements and production efficiency. The demand for production equipment with a high degree of modernization has been greatly increased, so as to improve the benefits of enterprises, and the development of new high-efficiency intelligent production equipment has become the driving force for the development of the manufacturing industry. [0003] However, at present, screw connections on the production line are used in every device, and the screw and nut tightening devices hardly form a production line scale, which ...
