Description

Torque wrench synchronous calibration system

The present invention is a torque wrench synchronous calibration system, and in particular, an innovative system that can synchronously adjust and calibrate multiple sets of power torque wrenches.

There are various common torque wrench calibration mechanisms on the market, such as China New Type Announcement No. CN211504522U "A Calibration and Verification Fixture for a Torque Wrench", No. CN215414352U "A Torque Testing Fixture", or Taiwan Invention Publication No. 201207364 "Electronic Torque Wrench Calibration Device and Its Application Method", No. 201429640 "A Constant Torque Measurement Method and Device", and No. 201721118 "Wrench Torque Testing Device and Torque Sensor". The calibration mechanisms of these torque wrenches are all one-to-one calibration modes. The reason is that the current application of torque wrenches mainly adopts manual methods to perform various bolt locking operations. Therefore, there is no need to use multiple sets of torque wrenches at the same time in practical operations. Ordinary operators cannot operate multiple sets of torque wrenches at the same time. There has never been any device that can accurately and quickly calibrate multiple sets of torque wrenches at the same time.

During the flange bolt locking operation of large pipe fittings, operators need to perform locking operations on multiple sets of bolts one by one and in sequence with various torque values. In order to speed up the bolt locking efficiency, the inventor team of this case invented a "pipe fitting flange bolt locking robot" with invention patent application number 110132920. This innovative pipe fitting flange bolt locking robot can synchronously drive multiple sets of power torque wrenches to perform bolt locking operations, which can greatly improve the efficiency of pipe fitting flange bolt locking.

However, the inventor team of this case found that although the pipe flange bolt locking robot can improve the efficiency of pipe flange bolt locking operation by several times, in the process of adjusting and calibrating multiple torque values of multiple sets of power torque wrenches, the operator still needs to use a torque detector to adjust and calibrate each set of power torque wrenches one by one. This will take a lot of time in the process of adjusting and calibrating multiple sets of power torque wrenches, making it impossible to achieve the best efficiency in the locking of pipe flange bolts.

To this end, the inventor team of this case has accumulated many years of experience in the research and development of technologies in the fields of electronics, electrical machinery, and machinery. They have conducted research and analysis on the above-mentioned issues and invented this case.
