An Intelligent Wrench Control System

Abstract

The invention belongs to the technical field of connection and fastening, and relates to an intelligent wrench control system. The intelligent wrench control system comprises a power source, a torquecontroller, a power wrench and a torque measurement feedback sleeve, wherein the power source is connected with the power wrench through the torque controller, the power wrench rotates a target fastener by sleeving the torque measurement feedback sleeve, the torque controller is connected with the torque measurement feedback sleeve in wireless mode, the torque measurement feedback sleeve is used for collecting real-time torque data, and feeds the collected torque data back to the torque controller, and the torque controller controls intensity and blocking and unblocking of power output from the power source to the power wrench. The intelligent wrench control system performs accurate fastening work by presetting torque value of the target fastener, improves accuracy and efficiency of the fastening work, and is easy and convenient to operate, and accurate and rapid in target torque fastening work.

Description

technical field [0001] The invention belongs to the technical field of connection and fastening, and in particular relates to an intelligent wrench control system. Background technique [0002] A wrench is a commonly used tool. The traditional wrench uses the principle of leverage to twist bolts, screws, nuts and other openings or hole-hole fastener tools that hold the bolts tightly. After the development of technology, the wrench tool has developed from the original principle of human leverage to The form of electric torque is used as an index to evaluate the bolt installation process. The torque value directly affects the bolt installation process. Currently, there are many automatic or semi-automatic torque wrenches available. However, these wrenches are all used in light bolt assembly on the workshop assembly line. In petrochemical, wind power, bridges, railways and other outdoor workplaces that require heavy bolt assembly, there is no suitable automatic wrench to choose...

AI Technical Summary

Problems solved by technology

However, these wrenches are all used in light bolt assembly on the workshop assembly line. In petrochemical, wind power, bridges, railways and other outdoor workplaces that require heavy bolt assembly, there is no suitable automatic wrench to choose from, and relatively primitive operations are still used. tool

The traditional heavy-duty bolt fastening process uses non-precision impact wrench or hydraulic wrench. The error value of impact wrench is as high as more than 20%. The error value of hydraulic wrench is much higher than that due to the need to manually adjust the oil pressure and the introduction of human factors. its nominal range

[0003] The bad thing is that due to the lack of reliable precision tightening tools, the quality of assembly cannot be guaranteed in some important projects, which has led to serious safety accidents, such as several accidents in the current petrochemical industry that caused heavy losses

In practice, there are often low-level operators who are unwilling to strictly abide by the procedures because of the bulky and cumbersome existing tools, and use simple and rough methods to operate, and there is no good method for monitoring and tracking, resulting in complete loss of control of assembly quality
