[0028] A display screen 4 is connected to the upper side of the testing device main body 1. The display screen 4 is electrically connected to the motor speed measuring instrument 22. The positioning concave plate 13 is used to fix the DC motor main body 12. Two mounting frames 14 are fixedly connected to the other side of the positioning concave plate 13. A second bolt 15 is threadedly connected to the upper sides of the two mounting frames 14. The lower side of the second bolt 15 penetrates through the mounting frame 14 and extends to the lower side of the mounting frame 14. A limiting pressure plate 16 for fixing the DC motor main body 12 is installed on the lower sides of the two second bolts 15.

[0029] On the upper side of the main body 1 of the test device, two guide plates 17 for guiding the displacement plate 5 are fixedly installed. Through the arrangement of the guide plates 17, the movement of the displacement plate 5 can be guided by the two guide plates 17, so that the displacement plate 5 can drive the DC motor to move to the detection position, facilitating the detection of the rotation speed of the DC motor. The left side of the displacement plate 5 is rotatably connected with a second gear rod 18. Through the installation and use of the first gear rod 7 and the second gear rod 18, the second gear rod 18 can drive the first gear rod 7 to rotate slowly, so as to facilitate the adjustment of the DC motor to the detection position, which is convenient to use.

[0033] The working principle of a DC motor test device provided by the present utility model is as follows:

[0034] By rotating the first bolt 10, the first bolt 10 can drive the positioning concave plate 13 to adjust and move. At this time, the positioning concave plate 13 can be adjusted up and down. Then, a plurality of DC motor main bodies 12 are placed on the positioning concave plate 13, and then the plurality of DC motor main bodies 12 are sequentially installed inside the tooling circular plate 8. Then, the two second bolts 15 are rotated respectively, and the two second bolts 15 can drive the two limiting pressing plates 16 to move downward to squeeze and position the DC motor main body 12, so that DC motors of different sizes can be flexibly clamped and fixed, improving the adaptability of the DC motor test device. Then, the servo motor 19 drives the second gear rod 18 to rotate, and the second gear rod 18 can drive the meshed first gear rod 7 to rotate. In this way, the DC motor main bodies 12 on the tooling circular plate 8 can be sequentially rotated to the detection position, so that a plurality of DC motors can be batch-detected, improving the test efficiency of the DC motor test device;

[0035] By starting the electric push rod 3, the electric push rod 3 can drive the tooling circular plate 8 at the displacement plate 5 to move to the right, so that the DC motor main body 12 can be clamped into the mounting seat 25 of the motor speed measuring instrument 22. At this time, the rubber pad 23 inside the mounting seat 25 can increase the friction force with the output shaft of the DC motor main body 12, so that the DC motor main body 12 can be positioned in the mounting seat 25. Then rotate the fourth bolt 24 so that the fourth bolt 24 can squeeze and position the output shaft of the DC motor main body 12 to ensure the stability of the mounting seat 25. Then the motor speed measuring instrument 22 can detect the speed of the working DC motor main body 12, and the display screen 4 can display the speed parameters of the DC motor.
