Error-proof electric screwdriver, controller and computer tightening system

Abstract

The invention discloses an error-proof electric screwdriver which comprises an electric screwdriver body. An electric motor shell is arranged on one side of the electric screwdriver body, an electric motor is arranged in an inner cavity of the electric motor shell, and the shaft part of the electric motor is connected with a blade retainer; and the blade retainer is provided with screwdriver blades selected properly with corresponding and matched screws in a disassembly mode. The electric screwdriver and a hot spot controller for relay use transmit and receive data through wireless communication, so that large-range moving and tightening operation is facilitated, the screwdriver can be conveniently inserted into large-scale equipment for assembly without being pulled by a cable, so that the work is more facilitated, and the assembly error-proofing requirement of large-scale complex equipment is met.

Description

technical field [0001] The invention relates to the technical field of mechanical assembly, in particular to an error-proof electric screwdriver, a controller and a computer tightening system. Background technique [0002] In the screw tightening operation, the current electric screwdriver cannot count the torque and tightening results, and cannot guarantee the final quality of diverse and complex tightening assemblies. [0003] At present, the existing method for judging the tightening results is as follows: the electric screwdriver detects the internal current A and the duration L waveform characteristics to judge the normal and abnormal results, the value is fixed and cannot be adjusted; [0004] The principle of system collaboration is: the architecture is MQQT server + processing equipment + electric screwdriver, the MQQT server is the center of the system, the server sends product and process information to the processing equipment, and the processing equipment collect...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the existing error-proof function system is wired connection, which is inconvenient for large-scale equipment assembly, and the judgment of qualified or abnormal standard parameters is single, which is not suitable for error-proofing of the assembly system of adjustable torque electric screwdrivers. In addition, the centralized system is complex and costly. High, the product line sometimes requires a decentralized distributed system
