TORQUE WRENCH CALIBRATION AUTOMATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/204593
Kind Code:
A1
Abstract:
The present invention provides a torque wrench calibration automation system that is capable of eliminating backlash between a handle part and a body part by installing an elastic contact member on a side of a jaw and lightly turning the side of the handle part first before the front surface of the jaw comes into contact with the outer circumferential surface of the handle part of a torque wrench. The torque wrench calibration automation system of the present invention comprises: a body part; a handle rotation drive part; and a handle push drive part, wherein the body part includes a calibrator that collects data, transmits the data, and receives control signals, a head fixing part that fixes the position of a head part of a torque wrench, a body part base with a flat top surface, and a handle base that moves linearly from the top of the body part base; the handle rotation drive part includes a handle rotation motor installed on the handle base of the body part, and a handle rotation module connected to the front end of the handle rotation motor and rotating the handle part of the torque wrench; and the handle rotation module includes an air pressure supply part that provides air pressure required when mounting or dismounting the handle part of the torque wrench, and a chuck provided with a plurality of jaws that operate to grip or release the rear end of the handle part of the torque wrench in the circumferential direction by using the supplied air pressure so as to mount the torque wrench to the body part, wherein each of the jaws has an elastic contact member formed of an elastic material installed on one side thereof.
