Specifically, before the detection operation, the braking torque measurement tool 100 needs to be installed on the flywheel disc 200 of the vertical host, that is, the clamping main body 10 can be firstly placed on the surface of the flywheel disc 200, then the first clamping assembly 20 is connected with the first end of the clamping main body 10, the first end of the clamping main body 10 is fixedly clamped with the flywheel disc 200, then the second clamping assembly 30 is connected with the second end of the clamping main body 10, and the second end of the clamping main body 10 is fixedly clamped with the flywheel disc 200, so that the braking torque measurement tool 100 and the flywheel disc 200 can be assembled and fixed into a whole, finally, the torque wrench 300 is connected with the clamping main body 10 and then is rotated, and the braking torque value of the vertical host can be measured quickly and accurately. Compared with the prior art, the brake torque measurement tool 100 is small in number of parts, convenient to install and operate, time-saving and labor-saving, and capable of guaranteeing the efficiency of brake torque measurement operation of the vertical host.
In this embodiment, the flywheel panel 200 is a circular plate, which is coaxially connected to the driving shaft of the vertical main machine, and when rotating, the flywheel panel can synchronously drive the driving shaft to rotate.
With reference to fig. 2 to 4, in some embodiments, the clamping body 10 includes a holder 11 and a connecting block 12, the connecting block 12 is disposed on the holder 11, the connecting block 12 is provided with an assembling hole 121, and the assembling hole 121 is configured as a non-circular hole. The holder 11 is a strip-shaped rectangular plate made of metal and other materials with certain structural strength and rigidity, and the influence on the measurement accuracy caused by deformation when the holder is subjected to torsional force is avoided.
When installed, the cage 11 rests directly on the upper disc surface of the flywheel disc 200. In this embodiment, a positioning hole is formed in the center of the holder 11, and the positioning hole is used for positioning and matching with the central hole of the flywheel panel 200. Through the alignment of the positioning hole and the central hole, the accurate installation and positioning of the retainer 11 and the flywheel disc 200 can be ensured.
