The number of steering sensors 51 is usually set to two, respectively sensing left steering and right steering. Each steering sensor 51 is connected to the control box 2 by a connecting line to transmit the steering test signal.

[0048] In one embodiment, the steering assembly includes a rotating rod 511, a rotating protective cover 57, a steering wheel 59 and a bearing 58. The rotating rod 511 is aligned with the mounting hole. The rotating rod 511 is cylindrical and has a spring 512 at the bottom. The rotating protective cover 57 is sleeved on the outer surface of the rotating rod 511 and rotates with the rotation of the rotating rod 511. The bearing 58 and the steering wheel 59 are both sleeved on the outer surface of the rotating protective cover 57, and the steering wheel 59 rotates with the rotation of the rotating protective cover 57. A reflective film is also provided on the outer side of the steering wheel 59.

[0049] When the motor 6 is mounted on the motor mounting base 54 and connected to a power source, the output shaft of the motor 6 abuts against the rotating rod 511 and drives the rotating rod 511 to rotate, thereby driving the steering wheel 59 to rotate. The steering sensor 51 tests the steering direction of the motor 6 by sensing the reflective film.

[0050] In this embodiment, the rotating rod 511 is a cylindrical rod, and a spring 512 is arranged at the bottom of the rotating rod 511. The rotating protective cover 57 is in the shape of a circular ring, and its inner diameter is the same as the diameter of the rotating rod 511. It is sleeved on the outer surface of the rotating rod 511 and surrounds the spring 512. The rotating protective cover 57 is used to protect the rotating rod 511 and rotates with the rotation of the rotating rod 511, and can avoid direct contact with the steering wheel 59 to generate wear during the rotation. A steering wheel 59 and a bearing 58 are sleeved on the outer surface of the rotating protective cover 57. There are two bearings 58, which are respectively located above and below the steering wheel 59. A recessed position corresponding to the bearing 58 is provided on the square plate 56 of the steering test mechanism 5. The bearing 58 below the steering wheel 59 is arranged in the recessed position. The bearing 58 can support the rotation of the rotating protective cover 57 to reduce friction. The steering wheel 59 is a cylindrical structure, which is sleeved on the outer surface of the rotating protective cover 57 and rotates with the rotation of the rotating protective cover 57. A reflective film is provided on the outer side of the steering wheel 59. There are multiple reflective films, which are spaced and evenly arranged on the outer surface of the steering wheel 59.

When the motor 6 is installed on the motor mounting seat 54, the second protrusion of the motor output shaft and the rotating rod 5 The first protrusions of 11 cannot correspond to each other, and the output shaft of the motor 6 presses the rotating rod 511 downward, and the rotating rod 511 compresses the spring 512 at the bottom. When the motor 6 is connected to the power supply and started, the output shaft starts to rotate. During the rotation process, the second protrusion also rotates until it complements the first protrusion of the rotating rod 511. At this time, due to the action of the spring 512 at the bottom of the rotating rod 511, the rotating rod 511 is pushed upward, and the second protrusion complements the first protrusion, so that the output shaft of the motor 6 can better drive the rotating rod 511 to rotate, and then drive the steering wheel 59 to rotate, so that the steering sensor 51 can be tested.

[0052] In one embodiment, a terminal interface is disposed on the top surface of the power supply socket 55, and a probe 510 is disposed in the terminal interface for contacting the lead wires in the connection terminals of the motor 6 to connect the power supply.

[0053] In this embodiment, the terminal interface is a downwardly concave groove connected to the top surface of the power socket, and a probe 510 is arranged in the groove. There are two probes 510, which are respectively used to contact the red lead wire and the black lead wire in the terminal of the motor 6. The two probes 510 are connected to the control box 2 through a connecting wire. When the terminal of the motor 6 is inserted, the red lead wire and the black lead wire are properly contacted with the two probes 510 respectively, and the power is connected. A ball screw can also be set on the side wall of the groove. When the terminal is inserted into the groove, the head of the ball screw will be squeezed. Since the head is connected to a spring, the spring squeezes the head of the ball screw toward the terminal, thereby giving the terminal a thrust, so that the terminal can be stuck in the groove, and a certain force is required to pull the terminal out.

[0054] In one embodiment, the indicator light 43 includes a turn indicator light, a polarity indicator light, and a lead indicator light. The turn indicator light, polarity indicator light, and lead indicator light display the correct and incorrect results of the motor direction, magnetic steel polarity, and lead wire in green and red respectively.

[0055] In this embodiment, there are multiple indicator lights 43, and each indicator light 43 is connected to the control box 2 by a connecting wire, which is used to display the correct and incorrect results of the motor direction, magnetic polarity, and lead wire respectively. The red and green colors of an indicator light 43 can be used to display error or correctness, or different indicator lights 43 can be lit to represent different test results.

[0056] The working process of the motor steering test tooling of the present invention is as follows: connect the connecting wires of the control box 2, the switch box 4, and the steering test mechanism 5, and start the power switch on the control box 2; put the motor 6 into the motor mounting seat 54, the Hall sensor 52 tests the polarity of the motor magnet and transmits a signal to the control box 2, the control box 2 judges, if qualified, the polarity indicator light on the switch box 4 lights up green, if unqualified, the polarity indicator light on the switch box 4 lights up red, and the buzzer sounds an alarm to remind; when the polarity test of the motor 6 magnet is qualified, the wiring terminal of the motor 6 is inserted into the power access seat 55, so that the motor 6 is connected to the power supply, and at the same time, the optical fiber sensor 53 starts to work, and tests whether the color of the lead wire in the sensing area is a red lead wire. If the color of the lead wire is black, the test button 42 cannot be started to switch on. Start the steering test. If the lead wire color is red, the lead indicator light will light up green. When the lead indicator light is green, press the test button 42, the motor 6 starts to start, the output shaft drives the rotating rod 511 to rotate, and then drives the steering wheel 59 to rotate. The steering sensor 51 senses the reflective film on the steering wheel 59 and sends a signal to the control box 2. After the control box 2 judges the steering signal, it sends the judgment result to the switch box 4. If the steering is correct, the steering indicator light will light up green, the motor 6 will stop working, and the steering test of the entire motor 6 will be completed. If the steering is wrong, the steering indicator light will light up red, and the buzzer will sound an alarm to remind you. The test tooling can only be reset after the authorized personnel inserts the key into the reset switch 41 to unlock it. After the motor 6 passes the test, the qualified motor is taken out and the tooling is reset before the next steering test can be carried out.
