when an error occurs during the torque test, the control unit 2 controls the test motor 19 to stop operating, and controls the brake motor 21 to intervene with the auxiliary brake cylinder 29, the plurality of T-shaped brake blocks 22 drive the contact brake blocks 23 to clamp the driving shaft 18, the corresponding pressure sensor 27 transmits the received pressure information to the control unit 2, the control unit 2 controls the brake motor 21 to run for a certain stroke after analyzing the pressure information until the pressure received by the pressure sensor 27 is equal to the set value in the control unit 2, the control unit 2 controls the brake motor 21 to keep still, meanwhile, the sensing assembly at the tail end of the auxiliary brake rubber pad 30 transmits the pressure information received by the sensing assembly to the control unit 2, the control unit 2 controls the auxiliary brake cylinder 29 to run for a certain stroke until the pressure received by the sensing assembly is equal to the set value in the control unit 2, and the control unit 2 controls the auxiliary brake cylinder 29 to keep a stop state.

The working principle is as follows: when a motor coil needs to be detected, the motor coil needing to be detected is placed into the first station 4 through an external mechanical arm or other transmission mechanisms, after the positioning sensor 6 detects that the coil is placed, the control unit 2 controls the limiting cylinder 7 to operate, the fixing frame 8 is pushed to one side to limit the coil shell 10, after the limiting is completed, the control unit 2 controls the operating platform 3 to rotate the driving shaft by 180 degrees, so that the positions of the first station 4 and the second station 5 are exchanged, the control unit 2 controls the heating cylinder 14 and the preheating gun 15 to synchronously operate, the coil is preheated, the phenomenon that the coil generates large temperature difference due to rapid temperature rise in the initial detection stage to influence the performance of the coil is avoided, the control unit 2 controls the propulsion motor 16 to operate, so that the test platform 17 drives the driving shaft 18 to be clamped with the test rotating shaft 11, and after the test motor 19 is started, the driving shaft 18 drives the test rotating shaft 11 and the coil in the coil shell 10 to rotate at high speed, the torque test is carried out, meanwhile, the two limiting cylinders 7 operate, the limiting effect of the fixing frame 8 on the coil shell 10 after the previous torque test experiment is removed, so that the tested motor coil is taken out by utilizing external transmission mechanisms such as mechanical arms, the high intelligence of the torque detection of the motor coil is realized through the detection method, and the detection efficiency and the accuracy of the coil are improved.

When an emergency condition is detected or the coil detection is finished during the test, the control unit 2 controls the test motor 19 to stop operating, and synchronously controlling the operation of the brake motor 21, so that the driving gear disc in the triangular chuck 20 drives the plurality of T-shaped brake blocks 22 to move towards the direction close to the driving shaft 18, and then the plurality of contact brake blocks 23 rapidly clamp the rotating driving shaft 18 through the plurality of T-shaped lugs 25, at the same time, the pressure springs are pressed, the pressure sensor 27 transmits the pressure information to the control unit 2 for analysis and comparison, when the pressure is equal to the set value in the control unit 2, the brake motor 21 stops operating, therefore, the clamping effect of the contact brake blocks 23 on the driving shaft 18 can be ensured, and the situation that the contact brake blocks 23 are subjected to thermal deformation to weaken the speed reduction effect because the contact brake blocks 23 decelerate the driving shaft 18 for multiple times in a short time is avoided.

In the process of decelerating the driving shaft 18 and the coil, the control unit 2 controls the two auxiliary brake cylinders 29 to synchronously operate, so that the two auxiliary brake rubber pads 30 matched with the rotating shaft in the coil shell 10 are close to each other, the one end with the fan 9 and the rotating shaft are quickly limited, the brake lag time caused by inertia and the like is shortened, the operation stroke of the auxiliary brake cylinders 29 is controlled through the sensing assembly, the auxiliary brake mechanism can keep a good auxiliary brake effect under the condition of multiple braking, the brake capacity is fully improved, the brake time is shortened, the test efficiency of the coil torque can be improved, and the damage influence on the coil and the test device can be prevented when emergencies occur.
