Multifunctional Torque Set Tool

Abstract

The invention discloses a multifunctional torsional sleeving tool which at least one set of constant-torsion screwdriver modules, a tire pressure module, a connecting module used for connecting the constant-torsion screwdriver modules and the tire pressure module and a driving module which can rotate to drive the constant-torsion screwdriver modules to rotate. Each constant-torsion screwdriver module comprises an outer sleeve, a tool bit which is detachably connected to the end of the outer sleeve and stressed convex buckles which are distributed on the surface of the tool bit at intervals, a cylindrical through groove is formed in the outer sleeve, and the inner side of the end of the through groove is provided with an inner thread; the tire pressure module comprises a pressure measuring sleeve, a pressure measuring mouth arranged at the end of the pressure measuring sleeve, a pressure measuring groove formed in the pressure measuring sleeve, a pressure guiding hole, a pressure bearing disc which can move up and down, a pressure bearing elastic part and a pressure measuring groove plug. According to the multifunctional torsional sleeving tool, the structure is simple, the screwdriver torsion can be adjusted, and the size of the tightening torsion can be controlled accurately, due to the fact that multiple sets of screwdrivers are arranged, multiple shape requirements can be met; tire pressure monitoring can be performed, operation is convenient, and measuring is precise.

Description

technical field [0001] The invention belongs to the field of hardware tools, in particular to a multifunctional torque set tool. Background technique [0002] On some precision instruments or equipment, the tightening torque of threaded connections is clearly limited, and when replacing or maintaining these precision instruments and equipment, it is often necessary to unscrew these threaded connections, replacement or maintenance-related After fitting, tighten it according to the set torque, such as the fixing bolts of the car battery terminal, the disassembly and assembly of the tire fastening bolts, etc. Usually, people use a screwdriver to manually tighten the threaded connection, and the tightening force is usually judged by the worker's experience. Therefore, when tightening some threaded connections with specific torque requirements, in order to prevent the bolts from loosening, workers generally screw the threaded connections to the limit position to ensure tightenin...

AI Technical Summary

Problems solved by technology

However, for threaded connections with torque requirements, if the tightening torque is too large, the threaded connection will be connected to two components under high torque for a long time, which will not only cause cracks or even breakage of the threaded connection due to excessive stress, but also The precision equipment connected by the threaded connection is subjected to excessive pressure and causes deformation, so that the instrument cannot work normally, and eventually leads to failure or accidents
