Description

Technical Field

[0001] The utility model relates to the technical field of motor detection, in particular to a motor detection device. Background Art

[0002] The motor is a core component of new energy vehicles, and its characteristics determine the vehicle's primary performance. Therefore, to calibrate the vehicle's performance, motor performance testing is often performed. Because automotive motors vary in size, testing motors of varying sizes requires prefabricating supports tailored to the size of the motor being tested, completing the testing process.

This application improves the problem of low detection efficiency when detecting motors of different sizes in traditional methods, and can drive the effect of improving the detection efficiency of the motor.

[0004] The above-mentioned motor detection equipment is to fix the motor and then move the motor to the vicinity of the test box, and use the test box to complete the motor detection task. However, in the actual operation process, the sizes of the motors are different. After the motor is clamped, it is impossible to ensure that the output end of the motor and the coupling of the test box are located at the same height and the same position. The above-mentioned equipment only has a relatively complex and cumbersome height adjustment mechanism at the motor, and lacks the necessary lateral adjustment mechanism for the position offset between the motor output end and the coupling. This means that the staff needs to manually adjust it based on experience, which not only takes a lot of time to fix and adjust the motor, but also there will be certain errors. Based on this, the utility model designs a motor detection equipment to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Please refer to Figure 1-Figure 3, a motor detection device, comprising:

[0027] Working frame 1: A moving frame 2 is installed on the top of the working frame 1 and is used to fix the motor. A first rack 3 is installed on the back of the moving frame 2;

[0028] Driving mechanism: The driving mechanism is installed at the bottom of the inner cavity of the working frame 1 and is used to move the moving frame 2;

[0029] Working mechanism: The working mechanism is installed on one side of the inner cavity of the working frame 1 and is used for detecting the motor. The working mechanism includes a lifting assembly, an adjustment assembly and a detection assembly. The lifting assembly is installed at the bottom of the inner cavity of the working frame 1 and is used for adjusting the height of the detection assembly. The adjustment assembly is installed on the top of the lifting assembly and is used for lateral adjustment of the detection assembly. The detection assembly is located on one side of the adjustment assembly and is used for detecting the motor.

[0030] The lifting assembly includes a hydraulic telescopic rod 4 installed at the bottom of the inner cavity of the working frame 1, a lifting frame 5 is installed on the top of the hydraulic telescopic rod 4, and a limit rod 6 is also installed between the lifting frame 5 and the bottom of the inner cavity of the working frame 1. The limit rod 6 is distributed in a matrix array.

[0031] The adjustment component includes a servo motor 7 installed in the inner cavity of the lifting frame 5, a connecting seat 8 is installed on the back of the servo motor 7, a screw rod 9 is installed between the servo motor 7 and the connecting seat 8, the outer ring of the screw rod 9 is threadedly connected to a moving block 10, and a fixed rod 11 is also installed between the servo motor 7 and the connecting seat 8. The moving block 10 is slidably sleeved on the outer ring of the fixed rod 11.

[0032] The detection assembly includes a detection box 12 installed on one side of the moving block 10 . A detection shaft 13 is installed in the inner cavity of the detection box 12 , and a coupling 14 is installed on one side of the detection shaft 13 .

[0033] In this embodiment of the present invention, stepper motor 15 is activated to drive movable frame 2, causing coupling 14 to connect to the motor output terminal. Then, the relevant testing equipment within test box 12 is activated to perform various performance tests on the motor. Testing shaft 13 rotates synchronously with the motor output terminal via coupling 14, thereby simulating actual motor operation and ensuring the accuracy and reliability of the test results. The specific operating principle can be found in patent publication number CN217954662U and will not be detailed here.

[0034] Please refer to Figures 1-4 The driving mechanism includes a stepper motor 15 installed at the bottom of the inner cavity of the working frame 1. A rotating shaft 16 is installed on the top of the stepper motor 15. A first gear 17 is fixedly connected to the top of the rotating shaft 16. The first gear 17 is engaged with the first rack 3. A limiting component is also installed between the moving frame 2 and the working frame 1.

[0035] The limiting assembly includes a slide groove 18 opened at the bottom of the inner cavity of the working frame 1, a slider 19 is installed at the bottom of the moving frame 2, and the slider 19 is slidably connected in the inner cavity of the slide groove 18. A clamping assembly is also installed on the top of the moving frame 2.

[0036] The clamping assembly includes a fixed frame 20 installed on the top of the moving frame 2, an electric push rod 21 is installed at the bottom of the inner cavity of the fixed frame 20, a second rack 22 is installed on the top of the electric push rod 21, a pin 23 is installed in the inner cavity of the fixed frame 20, a second gear 24 is installed on the outer ring of the pin 23, the second gear 24 and the second rack 22 are engaged with each other, a clamping plate 25 is installed on the top of the second gear 24, and a clamping frame 26 is installed on the top of the clamping plate 25.

[0037] In the embodiment of the present invention, the electric push rod 21 is started to retract, driving the second rack 22 to move downward. Since the second rack 22 is engaged with the second gear 24, the second gear 24 rotates accordingly, driving the top clamping plate 25 and the clamping frame 26 to move closer to the center until the motor is firmly clamped.

[0038] During use, the motor to be tested is placed in the fixed frame 20 at the top of the mobile frame 2. The electric push rod 21 is started to retract, driving the second rack 22 to move downward. Since the second rack 22 is engaged with the second gear 24, the second gear 24 rotates accordingly, driving the clamping plate 25 and the clamping frame 26 at the top to move closer to the center until the motor is firmly clamped. Start the stepper motor 15 at the bottom of the inner cavity of the working frame 1, drive the rotating shaft 16 to rotate, and then drive the first gear 17 fixed at the top to rotate. Since the first gear 17 is engaged with the first rack 3 on the back of the mobile frame 2, the mobile frame 2 is driven in the horizontal direction to the vicinity of the detection box 12, realizing the initial positioning of the motor. The cooperation between the slide 18 and the slider 19 can limit the moving direction of the mobile frame 2.

[0039] Once the motor is in position, the hydraulic telescopic rod 4 is activated. Its telescopic motion causes the lifting frame 5 and all components on it to rise or fall vertically until the coupling 14 in the detection box 12 approaches the motor's output terminal. During this process, the limit rod 6 ensures the stable movement of the lifting frame 5, preventing it from shifting.

[0040] After the lifting assembly completes height adjustment, servo motor 7 is activated. This drives screw 9 to rotate. Because screw 9 is threadedly connected to moving block 10, which is slidably mounted on fixed rod 11, moving block 10 moves laterally along the axis of fixed rod 11. This movement drives detection box 12 and its coupling 14 laterally until coupling 14 and the motor output are precisely aligned, completing the subsequent detection process.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
