Detection equipment and detection method for torque spanners

Abstract

The invention discloses a detection technology for torque spanners. Detection equipment for the torque spanners comprises a rack, a dynamic torque sensor and a bolt clamping part, wherein one end of arotary shaft of the dynamic torque sensor is used for installing the torque spanner, and the other end of the rotary shaft of the dynamic torque sensor is connected with the bolt clamping part; the rack is provided with a positioning bracket for installing the dynamic torque sensor; a shell of the dynamic torque sensor is arranged on the positioning bracket in a supporting manner, so that a rotary shaft of the dynamic torque sensor can rotate along the torque spanners. According to the detection equipment disclosed by the invention, the dynamic torque sensor is adopted, the rotary shaft of the dynamic torque sensor rotates along the torque spanners, so that no impact is caused to the torque sensor, the actual state when a bolt is screwed can be simulated, the torque in the screwing process of the bolt can be dynamically detected, and the detection equipment can be used for verification, calibration and test of electric and pneumatic torque spanners; the sampling frequency is very high; an instantaneous peak value output by the detected torque spanners can be acquired, so that higher measurement accuracy can be guaranteed.

Description

technical field [0001] The invention relates to the field of torque wrench detection, in particular to a torque wrench detection device and a detection method thereof. Background technique [0002] Torque wrenches are widely used in automobile manufacturing, equipment manufacturing, transportation and other industries. With the development of the industrial level, the control of the assembly process is becoming more and more strict. The tightening of bolts and nuts is an important part of the control of the assembly process of industrial products. Therefore, the performance of the torque wrench is getting more and more attention, especially the electric and The pneumatic torque wrench is driven by electricity and gas pressure, and can directly affect the quality of assembly through the precise control of its output torque, which is of great significance for reducing the occurrence of traffic accidents and reducing the safety hazards of public works. [0003] The torque wren...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the problem that in the existing torque wrench detection device, the sensor is fixedly installed with the fixed stand, so that the sensor cannot rotate together with the torque wrench, and the accuracy of the torque indication is low. The impact mode of the sensor will cause the torque to attenuate, resulting in the technical problem of inaccurate torque detection value. A torque wrench detection device and its detection method are provided. The detection device uses a dynamic torque sensor, and the rotating shaft of the dynamic torque sensor rotates with the torque wrench , will not impact the torque sensor, can simulate the actual state of the bolt tightening, dynamically detect the torque during the bolt tightening process, and can be used for the verification, calibration and testing of electric and pneumatic torque wrenches; and the sampling frequency is very high , can collect the instantaneous peak output of the tested torque wrench to ensure higher measurement accuracy
