[0032] The outer wall of the machine body 1 is fixedly provided with a control console 24, and each sensor in the detection assembly is electrically connected to a processor in the control console 24 through a data line.

[0033] The implementation principle of the detection device for motor machining and production is as follows: when in use, the motor 23 is placed between the two positioning blocks 20, the inner walls of the two positioning blocks 20 are shaped to be matched with the outer wall of the motor 23, so that the motor 23 is embedded between the two positioning blocks 20, the motor 23 is positioned, and the motor 23 is prevented from shaking, then the control console 24 controls the clamping cylinder 21 to start, the output ends of the two clamping cylinders 21 drive the two clamping blocks 22 to press down, and the top of the motor 23 is pressed tightly, and at this time, the motor 23 is fixed.

[0034] When detecting, first detect the rotating speed of the motor 23, start the direct drive motor two 18, the direct drive motor two 18 drives the block to push the connecting block 13 to move, the connecting block 13 drives the moving plate 12 to move left and right, the moving plate 12 drives the slider 11 to slide on the outer wall of the guide rail 10, and the slider 11 plays a guiding role, so that the moving plate 12 always moves linearly left and right, until the hollow structure on the outer wall of the fixed frame one 14 driven by the moving plate 12 is located directly above the magnetic turntable 25, at this time the direct drive motor two 18 stops, the direct drive motor one 9 starts, its driving block drives the lifting block 7 to move down, the lifting block 7 slides on the outer wall of the two guide rods 6, and the lifting block 7 plays a guiding role, so that the lifting block 7 linearly and stably rises and falls, the lifting block 7 drives the mounting plate 8 and the moving plate 12 to descend, and the moving plate 12 drives the fixed frame one 14 and the Hall sensor 15 on the top of the fixed frame one 14 to approach the magnetic turntable 25.

[0035] After starting the motor 23, the Hall sensor 15 outputs a pulse signal, which is processed by the signal processing circuit in the console 24, and the processor built in the console 24 calculates according to the following formula and displays the rotating speed of the motor 23 on the display panel on the outer wall of the console 24, and the principle is that the Hall sensor 15 is based on the Hall effect, and a magnetic turntable 25 is installed on the output shaft of the motor 23, when the magnetic turntable 25 rotates with the motor 23, the Hall sensor 15 will sense the change of the magnetic field. Whenever a small magnet passes through the Hall sensor 15, a Hall potential pulse will be generated, the number of pulses in a unit time is detected to calculate the rotating speed of the motor 23, assuming that the number of pulses in a unit time t is n, and the number of magnets on the turntable is m, then the rotating speed N of the motor is 60n / (mt) (unit: rpm);

[0036] When detecting the torque of the motor 23, the direct drive motor one 9 drives the lifting block 7 to rise, so that the fixed frame one 14 rises and resets, and then the direct drive motor two 18 is started, the driving block of the direct drive motor two 18 drives the moving plate 12 to move right through the connecting block 13, so that the fixed frame two 16 moves right, until the hollow structure on the outer wall of the fixed frame two 16 is located directly above the magnetic turntable 25, after starting the motor 23, the output shaft drives the magnetic turntable 25 to rotate, the torque changes the magnetic properties of the magnetic turntable 25, the magnetic elastomeric sensor head 17 detects the change of the output signal, the signal is processed by the processor in the console 24 and displayed on the display panel on the console 24 for recording, and the principle is that the magnetic elastomeric sensor head 17 utilizes the magnetostriction effect of ferromagnetic materials. When the output shaft of the motor 23 drives the magnetic turntable 25 to rotate and is subjected to torque, the magnetic domain structure inside the magnetic turntable 25 will change, causing the magnetic permeability of the magnetic turntable 25 to change, at this time through the excitation coil and the detection coil on the magnetic elastomeric sensor head 17, the excitation coil generates an alternating magnetic field, when the magnetic permeability of the magnetic turntable 25 changes, the inductance or induced electromotive force of the detection coil will change, and this change is related to the size of the torque.
