[0044] Multiple hand wheels are fixed on the side surface of detection bench 110, each hand wheel corresponds to each detection channel, and the multiple hand wheels are used to load torque or unload torque on the measured torque wrench.

[0045] Through the above technical solution, multiple detection channels are set, which can detect different torque ranges of the measured torque wrench, and the torque detection range is wide. When detecting different torque ranges of the measured torque wrench, the detection device does not need to be replaced. Detection instrument is used to perform detection operation and data display, and multiple hand wheels are used to load or unload torque on the measured torque wrench, which is simple in structure and easy to operate.

[0046] In one possible embodiment, the multiple detection channels include a first detection channel 120, a second detection channel 130 and a third detection channel 140. The torque detection range corresponding to the first detection channel 120 is greater than the torque detection range corresponding to the second detection channel 130, and the torque detection range corresponding to the second detection channel 130 is greater than the torque detection range corresponding to the third detection channel 140.

[0047] Among them, the first detection channel 120 represents the first detection position, the second detection channel 130 represents the second detection position, and the third detection channel 140 represents the third detection position.

[0058] In the embodiment, the multifunction integrated chip is an ultra-large scale integrated chip.

[0060] The detection operation system integrates multiple detection functions in the display instrument 150, and is easy to operate.

[0061] The operator can operate the detection operation system on the display instrument 150 to perform a detection operation on the torque wrench to be detected, and the display instrument 150 displays the detection operation system and the data detected on the torque wrench to be detected, so that the operator can intuitively analyze the data and calibrate the torque wrench to be detected by operating the display instrument 150.

[0065] As Figure 1 , Figure 2 shown, in a possible embodiment, the multi-channel torque wrench detection device 100 further includes a counterforce arm 200, and the counterforce arm 200 is arranged on the moving rail 190 of the top surface of the detection table 110. The counterforce arm 200 is used to support the torque wrench to be detected and balance the counterforce received by the torque wrench to be detected.

[0066] The counterforce arm 200 can include a sliding block 201, a support rod 202, and an adjusting rod 203. The sliding block 201 is in contact with the moving guide rail, and the sliding block 201 can reciprocate along the moving guide rail.

[0070] The counterforce arm 200 moves along the moving track 190 to correspond to the torque detection range of the corresponding detection channel.

[0071] In a possible embodiment, the counterforce arm 200 further comprises a fine adjustment slider 204, and the counterforce arm 200 adjusts the position of the to-be-detected torque wrench of different ranges on the counterforce arm 170 through the fine adjustment slider 204.

[0072] The fine adjustment slider 204 is arranged on the support rod 202, and specifically, the fine adjustment slider 204 is arranged on the support rod 202 between the first adjusting branch and the second adjusting branch of the adjusting rod 203. The fine adjustment slider 204 is internally provided with a ball, which can reduce resistance. When the to-be-detected torque wrench is not in a horizontal state during loading, the fine adjustment slider 204 can automatically float the to-be-detected torque wrench to the horizontal state to ensure the accuracy in the horizontal direction.

[0073] As an example, when the detection operation on the to-be-detected torque wrench is performed, the counterforce arm 200 is moved on the moving track 190 to the corresponding position matched with the selected detection channel, and the to-be-detected torque wrench is inserted through the through hole composed of the support rod 202 and the adjusting rod 203, so as to support the to-be-detected torque wrench and balance the force acting on the to-be-detected torque wrench. When the to-be-detected torque wrench is not in a horizontal state during loading, the fine adjustment slider 204 is used to automatically float the to-be-detected torque wrench to the horizontal state, thereby improving the stability of the detection process on the to-be-detected torque wrench and improving the measurement accuracy.
