[0026] Please refer to Figures 1 - 5, in this embodiment, a detection device for the mounting hole positions of a motor is provided, which includes a detection table 1. A column 2 is fixedly installed on the upper surface of the detection table 1. A pressing plate 3 is movably installed on the column 2. A detection module is arranged on the pressing plate 3. The detection module includes a rear column 4 fixed on the lower surface. A hole position detection plate 6 is movably installed on the front side of the rear column 4 through an elastic telescopic rod 5. And the motor 9 to be tested is arranged between the hole position detection plate 6 and the rear column 4. There is a mounting hole on the front side of the motor 9 to be tested. A detection nail 7 is arranged at the position corresponding to the mounting hole on the hole position detection plate 6. The elastic telescopic rod 5 includes a guide post 51 and a guide sleeve 52 that are movably sleeved with each other. And a spring 53 is connected between the guide post 51 and the guide sleeve 52. The spring 53 is installed inside the guide sleeve 52. The detection nail 7 includes a mounting piece 71 fixed on the hole position detection plate 6. A hole nail 72 is connected to the side of the mounting piece 71 close to the mounting hole. By arranging the pressing plate 3, the rear column 4, the elastic telescopic rod 5 and the hole position detection plate 6 on the detection table 1, the hole position depth and position of the motor 9 to be tested on the detection table 1 can be well detected by using the detection nail 7, and the detection accuracy is high. By replacing the hole position detection plates 6 of different specifications, the quick detection of the mounting hole positions of motors of different specifications can be completed. Specifically, during operation, the motor 9 to be tested is placed on the detection table 1. Among them, the rear column 4, the elastic telescopic rod 5 and the hole position detection plate 6 are the detection module. On the same detection table, the detection module of the same specification can be used for a long time to prevent the trouble of frequent replacement. By using the specification gasket 16, the positions of motors with different lengths but the same size interval of the mounting holes on the motor can be adjusted, so as to improve the applicable range of the motors that can be detected. Then, the hole position detection plate 6 is pulled forward to stretch the elastic telescopic rod 5. The pressing plate 3 is moved downward to drive the hole position detection plate 6 to move to one side of the motor 9 to be tested. The elastic telescopic rod 5 is released, and the detection nail 7 can be inserted into the mounting hole of the motor 9 to be tested.

[0027] In this embodiment, a pressure sensor 73 is connected between the mounting piece 71 and the hole nail 72. An error reporting buzzer 8 is also installed on the hole position detection plate 6. The error reporting buzzer 8 is electrically connected to the pressure sensor 73 through a controller. Among them, in order to further improve the intuitive effect of the detection result, by setting the pressure sensor 73, it can be judged whether the hole nail 72 penetrates into the corresponding mounting hole position according to the pressure received by the pressure sensor 73. When the pressure of the pressure sensor 73 is too high, it means that the hole nail 72 does not penetrate into the corresponding motor mounting hole position, so that it can be intuitively judged that the motor mounting hole position is unqualified.

[0028] In this embodiment, a motor shaft 10 is provided on one side of the motor 9 to be measured. A positioning plate 11 is fixedly connected to the side of the hole position detection plate 6 close to the motor shaft 10. The positioning plate 11 and the hole position detection plate 6 are arranged perpendicular to each other. The positioning plate 11 is located above the motor shaft 10. A positioning detection groove 12 is formed in the positioning plate 11. The positioning detection groove 12 includes a vertically arranged positioning groove 120, and a detection groove 121 communicated with the top side of the positioning groove 120 is provided. The detection groove 121 is horizontally arranged. A retaining piece 122 is arranged between the detection groove 121 and the positioning groove 120. The retaining piece 122 is movably clamped on the hole position detection plate 6. An inclined guiding groove 123 communicated with the bottom side of the positioning groove 120 is provided. Among them, in order to improve the positioning effect on the hole position detection plate 6 during detection, by providing the positioning plate 11, when the pressing plate 3 moves downward, the positioning plate 11 can be driven to move downward synchronously. The downward-moving positioning plate 11 can make its positioning groove 120 just snap onto the motor shaft 10. At this time, the positioning of the positioning plate 11 and the hole position detection plate 6 can be completed. Then, by removing the retaining piece 122, under the action of the contraction and reset force of the elastic telescopic rod 5, the positioning plate 11 and the hole position detection plate 6 can be driven to move in the direction of the mounting hole of the motor 9 to be measured. Through the detection groove 121, it is helpful for the positioning plate 11 to move synchronously in the direction of the motor 9 to be measured, ensuring the smooth progress of the detection. It should be noted that by using the inclined guiding groove 123, during the downward movement of the pressing plate 3, the front and rear depth positions of the positioning plate 11 and the hole position detection plate 6 can be guided and adjusted through the inclined guiding groove 123, so that the positioning plate 11 drives the hole position detection plate 6 to move in the front side direction of the motor 9 to be measured, that is, away from the mounting hole direction, so as to complete the stretching of the elastic telescopic rod 5, thus eliminating the trouble of manually pulling the hole position detection plate 6 forward in advance to stretch and move down the elastic telescopic rod 5.

[0029] In this embodiment, connecting threads 15 are provided on the outer surface of the column 2. A threaded sleeve 14 is threadedly connected to the connecting threads 15. An activity sleeve 13 is provided below the threaded sleeve 14. The activity sleeve 13 is movably sleeved on the outer surface of the column 2. The activity sleeve 13 is fixedly connected to the pressing plate 3. Among them, by providing the threaded sleeve 14, the activity sleeve 13 can be tightly pressed, so as to tightly press the pressing plate 3 downward, prevent the displacement of the motor 9 to be measured during detection, and improve the stability and detection accuracy during detection.
