Description

Technical Field

[0001] The utility model relates to the technical field of torque testing, in particular to a coupling torque testing and calibration device. Background Art

[0002] During the production and application of couplings, it is necessary to perform torque testing on the rotating shaft head of the coupling.

[0003] The torque test structure currently on the market is only suitable for torque testing of large quantities of couplings of the same specification. It is difficult to deal with coupling shaft heads of various sizes and specifications, and the position of the fixture needs to be adjusted continuously. The current clamping method is generally symmetrical clamping on both sides. This clamping method will cause the coaxiality of the shaft head and the torque test structure to deviate, resulting in fluctuations and inaccuracies in the experimental results.

[0004] To this end, we propose a coupling torque test and calibration device to solve the existing problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] During use, the coupling torque test and calibration device of the utility model can place the coupling to be tested at a specified position, and adjust the height of the main body through the lifting assembly so that the working end of the coupling is between the three clamping arms, and then rotate the three screws through the cap block so that the three clamping arms clamp and position the working end, and the working end and the rotating head are in a coaxial state;
