AI Technical Summary

Technical Problem

Existing stud wrenches that apply torque through thread characteristics may cause the stud to rotate inversely when reversely disassembled, the torque is inaccurate, and the thread is prone to deformation and fatigue cracking under the action of axial forces.

Method used

A torque tooling for double-headed studs is designed, including a sleeve assembly, a top tightening assembly and a connecting rod. By providing symmetrical slots on the sleeve assembly and a round hole in the top tightening assembly, the connecting rod is passed through the slots and round holes to connect the sleeve assembly and the top tightening assembly to achieve top tightening of the double-headed studs.

Benefits of technology

It effectively avoids thread failure, improves the assembly accuracy, assembly efficiency and reliability of double-headed studs, is simple to operate, has a long service life, and greatly improves production efficiency and saves labor costs.

Abstract

The utility model provides a moment tool for a double-end stud, which belongs to the field of moment tools, and comprises a sleeve assembly, a jacking assembly and a connecting rod, the sleeve assembly is provided with two symmetrical slotted holes, and the sleeve assembly is connected with one end of the double-end stud; a round hole is formed in the jacking assembly, and the jacking assembly is arranged in the sleeve assembly in a penetrating mode; the connecting rod penetrates through the groove hole and the round hole to be used for connecting the sleeve assembly and the jacking assembly. Wherein the jacking assembly makes contact with the end face of the double-end stud, the jacking assembly is rotated to move upwards / downwards along the groove hole, the rotation freedom degree of the jacking assembly is converted into the linear freedom degree through the groove hole, and jacking of the double-end stud is achieved. The double-end stud has the advantages of being easy to operate, long in service life and capable of effectively avoiding failure of threads and greatly improving the assembling efficiency and reliability of the double-end stud.
