Specific implementation mode

[0023] Refer to Figures 1 - 5 , an accuracy detection device for locomotive components, including the main body 1 of the detection device. A detection installation cavity is provided inside the main body 1 of the detection device. The locomotive motor 10 is arranged in the detection installation cavity, and the bottom plate 4 is fixedly installed in the detection installation cavity.

[0024] A "T"-shaped groove is provided on the bottom plate 4, and a sliding block 5 is movably installed in the "T"-shaped groove. The "T"-shaped groove provides a movement channel for the sliding block 5 and keeps it balanced during the movement process.

[0025] The sliding block 5 is fixedly connected to the mounting plate 6. The lower fixing frame 9 is fixedly installed on the mounting plate 6. The upper fixing frame 7 is arranged above the lower fixing frame 9. Fixing semi-rings 8 are provided at the connection ends of the upper fixing frame 7 and the lower fixing frame 9. The upper fixing frame 7 and the lower fixing frame 9 can complete the limiting and fixing of the locomotive motor 10 to keep the locomotive motor 10 stable.

[0026] The locomotive motor 10 is arranged between multiple fixing semi-rings 8. The locomotive motor 10 is connected with an output shaft 13. A limiting shaft 16 is installed at one end of the output shaft 13. A positioning shaft 14 is coaxially fixed on the output shaft 13. A detection body 15 is coaxially sleeved on the output shaft 13. The detection body 15 is located between the positioning shaft 14 and the limiting shaft 16. The output shaft 13 drives the detection body 15 to rotate at a high speed. The positioning shaft 14 and the limiting shaft 16 limit the detection body 15 to prevent the detection body 15 from flying out due to the centrifugal force generated by the high-speed rotation.

[0027] A first cylinder 2 is fixedly installed in the detection installation cavity. The output end of the first cylinder 2 is connected to a push rod 3. The push rod 3 is fixedly connected to a sliding block 5. When the first cylinder 2 is started, the first cylinder 2 drives the sliding block 5 to move in the "T"-shaped groove through the push rod 3, and the mounting plate 6 drives the locomotive motor 10 to move synchronously, so that the locomotive motor 10 moves to an appropriate position.

[0028] Referring to Figure 3 , the upper fixing frame 7 and the lower fixing frame 9 are of a symmetric structure centered on the center of the fixed semi-ring 8. Fixing holes are provided on both sides of the upper fixing frame 7, and screw rods 11 matching the fixing holes are installed on both sides of the lower fixing frame 9. The top of the screw rod 11 is sleeved with a fixing nut. By rotating the fixing nut, the screw rod 11 is pulled away from the upper fixing frame 7 and the lower fixing frame 9, so that the upper fixing frame 7 and the lower fixing frame 9 are separated, so that the locomotive motor 10 can be disassembled from the upper fixing frame 7 and the lower fixing frame 9, and at the same time it is more convenient to install the locomotive motor 10.

[0029] A machine door is provided on the front side of the detection device main body 1. The machine door is fixedly installed with a handle. The machine door is opened through the handle, so that the locomotive motor 10 can be taken out of the detection installation cavity.

[0030] A first mounting bracket 17 is fixedly installed on the surface of the detection device main body 1. The top of the first mounting bracket 17 is fixedly installed with a second mounting bracket 18. The first mounting bracket 17 and the second mounting bracket 18 can be disassembled, which can save a lot of space when the detection device is not in use.

[0031] The second mounting bracket 18 is fixedly provided with an "L"-shaped frame, and a second cylinder 19 is fixedly installed on the "L"-shaped frame. The "L"-shaped frame plays a role in supporting and fixing the second cylinder 19.

[0032] The second cylinder 19 is connected with a piston rod, the piston rod is connected with a contact plate 20, the contact plate 20 is arc-shaped, a pressure sensor 21 is arranged on the inner end surface of the contact plate 20, a controller 22 is fixedly arranged on the detection device main body 1, and the pressure sensor 21 is wirelessly connected to the controller 22.

[0033] Referring to Figure 1 , when detecting, the detection body 15 is fixed on the output shaft 13, and the second cylinder 19 drives the contact plate 20 to move up and down, so that the contact plate 20 is fixed within the qualified range of the detection body 15. When the locomotive motor 10 rotates for detection, the detection body 15 rotates on the output shaft 13. During the high-speed rotation of the detection body 15, the pressure sensor 21 performs detection. If it does not contact the contact plate 20, it means the detection is qualified. When the detection body 15 contacts the contact plate 20, the pressure sensor 21 transmits a signal to the controller 22, and the display on the controller 22 will send out a signal indicating that the detection is unqualified, thus completing the accuracy detection work of the locomotive parts.

[0034] The contact plate 20 is driven by the second cylinder 19 to adjust its position up and down, which can be used to detect test bodies 15 of different sizes, expanding the detection range.

[0035] Furthermore, to improve the accuracy of the dynamic balance detection of the output shaft 13 of the locomotive motor 10, to meet various detections of the output shaft 13, and to increase the practicality. Through the dynamic balance of the output shaft 13, the output shaft 13 of the locomotive motor 10 is adjusted specifically, thereby improving the service life of the output shaft 13 of the locomotive motor 10.

[0036] The working principle of the present utility model is as follows: When the second cylinder 19 is started, the second cylinder 19 drives the contact plate 20 to move up and down through the piston rod, thereby changing the distance between the contact plate 20 and the test body 15, and different-sized test bodies 15 can be detected. The upper fixing frame 7 and the lower fixing frame 9 can keep the locomotive motor 10 stable and facilitate the fixing of the locomotive motor 10.

[0037] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
