Description

Technical Field

[0001] This utility model relates to the field of motor shaft technology, and in particular to a motor shaft detection device. Background Technology

[0002] The motor shaft is a key component in a motor that supports rotating parts. It provides the central axis of rotation for the rotor, ensuring that the rotor can rotate stably in the magnetic field generated by the stator, thereby realizing the conversion of electrical energy into mechanical energy. When the motor is running, the shaft transmits the torque generated by the motor to the load, driving the load to rotate, thereby driving various mechanical equipment to work. The performance of the motor shaft needs to be tested during its production.

[0003] Currently, most testing devices for motor shafts fix one end of the shaft using a rotating mechanism, while the other end is fixed only by a contact pin. This can cause the end contacting the pin to wobble when the rotating mechanism drives the motor shaft to rotate, indicating that the fixing method is not secure enough and thus affects the accuracy of the motor shaft testing results. To address this issue, we propose a motor shaft testing device. Utility Model Content

[0004] The purpose of this invention is to provide a motor shaft detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A motor shaft testing device includes a testing platform. A fixed base is connected to the upper surface of the testing platform. A rotating bearing is embedded inside the fixed base. A connecting rod is connected to the inner ring of the rotating bearing. A drive motor is installed at one end of the connecting rod, and a rotating cylinder is connected to the other end of the connecting rod. A groove is formed on the upper surface of the testing platform. Two threaded rings are embedded in the inner sidewall of the groove. The inner rings of the two threaded rings are connected to a threaded rod. A threaded block is threadedly connected to the outer ring of the threaded rod. A forward and reverse motor is installed at one end of the threaded rod. A movable seat is connected to the upper surface of the threaded block. A fixed cylinder is installed on the left side of the movable seat. Two limiting components are formed on the upper surface of the testing platform. A sound sensor is installed on the upper surface of the fixed base, and a vibration sensor is installed on the upper surface of the movable seat.

[0007] In a further embodiment, each of the limiting components includes a groove, and a slider is slidably connected inside each groove, with the upper surface of each slider connected to the bottom surface of the movable seat.

[0008] In a further embodiment, a support plate is connected to the right side of the testing platform and the left side of the fixed base, and the upper surfaces of the two support plates are respectively connected to the outer surfaces of the drive motor and the forward and reverse motor.

[0009] In a further embodiment, an annular groove is provided on the right side of the fixed base, and an annular plate is slidably connected inside the annular groove. The right end of the annular plate is connected to the left side of the rotating cylinder.

[0010] In a further embodiment, the upper surface of the testing station is connected to two reinforcing seats, and the two reinforcing seats are respectively connected to the front and back of the fixing seat on their sides that are close to each other.

[0011] In a further embodiment, the bottom surface of the testing station is connected to two support bases, and the upper surface of both support bases is provided with mounting holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device first utilizes a forward and reverse motor to drive a threaded rod to rotate. The rotation of the threaded rod causes the threaded block to slide left and right on the movable seat. In turn, the left and right sliding of the movable seat causes the fixed cylinder to tighten around one end of the motor shaft. This prevents the motor shaft from wobbling up and down when the drive motor drives the rotating cylinder and the motor shaft to rotate, thereby indirectly improving the accuracy of the motor bearing test results.

[0023] Please see Figure 1-5In this utility model, a motor shaft testing device includes a testing platform 1. A fixed seat 3 is connected to the upper surface of the testing platform 1. A rotating bearing 4 is embedded inside the fixed seat 3. A connecting rod 5 is connected to the inner ring of the rotating bearing 4. A drive motor 6 is installed at one end of the connecting rod 5, and a rotating cylinder 7 is connected to the other end of the connecting rod 5. A groove 8 is formed on the upper surface of the testing platform 1. Two threaded rings 9 are embedded in the inner sidewall of the groove 8. A threaded rod 10 is connected to the inner ring of the two threaded rings 9. A threaded block 11 is threadedly connected to the outer ring of the threaded rod 10. A forward and reverse motor 12 is installed at one end of the threaded rod 10. A movable seat 13 is connected to the upper surface of the threaded block 11. A fixed cylinder 14 is installed on the left side of the movable seat 13. Two limiting components 2 are provided on the upper surface of the platform 1. A sound sensor 15 is installed on the upper surface of the fixed seat 3, and a vibration sensor 16 is installed on the upper surface of the movable seat 13. Each limiting component 2 includes a slide groove 201, and a slider 202 is slidably connected inside each slide groove 201. The upper surface of each slider 202 is connected to the bottom surface of the movable seat 13. The drive motor 6 can drive the connecting rod 5 and the rotating cylinder 7 to rotate, and then the rotating cylinder 7 can drive the motor shaft to rotate, thereby testing the performance of the motor shaft. By using the cooperation of the slide groove 201 and the slider 202, the movable seat 13 can be limited, so that the movable seat 13 can slide more smoothly when it slides left and right.

[0024] The right side of the testing table 1 and the left side of the fixed base 3 are both connected to the bearing plate 17. The upper surfaces of the two bearing plates 17 are connected to the outer surfaces of the drive motor 6 and the forward and reverse motor 12, respectively. The right side of the fixed base 3 is provided with an annular groove 18. An annular plate 19 is slidably connected inside the annular groove 18. The right end of the annular plate 19 is connected to the left side of the rotating cylinder 7. The two bearing plates 17 can support the drive motor 6 and the forward and reverse motor 12, which can make the drive motor 6 and the forward and reverse motor 12 run more stably. The annular groove 18 and the annular plate 19 can reinforce the rotating cylinder 7, which can make the rotating cylinder 7 rotate more smoothly.

[0025] The upper surface of the testing table 1 is connected to two reinforcing seats 20. The side of the two reinforcing seats 20 that are close to each other is connected to the front and back of the fixed seat 3, respectively. The bottom surface of the testing table 1 is connected to two support seats 21. The upper surface of the two support seats 21 is provided with mounting holes 22. The two reinforcing seats 20 can be used to reinforce the fixed seat 3, so that the connection between the fixed seat 3 and the testing table 1 can be more secure.

[0026] The working principle of this utility model is as follows:

[0027] When using this device, the operator first uses the support base 21 and mounting hole 22 to fix the testing platform 1 to the ground and connects the device to an external power source. Then, the operator inserts the end of the motor shaft to be tested into the rotating cylinder 7 and starts the forward and reverse motor 12 using the control panel. The forward and reverse motor 12 drives the threaded rod 10 to rotate, and the rotation of the threaded rod 10 causes the threaded block 11 to move the movable seat 13 and the fixed cylinder 14 to the left until the fixed cylinder 14 is fitted onto one end of the motor shaft. At this time, the operator starts the drive motor 6 using the control panel, and the drive motor 6 drives the connecting rod 5 and the rotating cylinder 7 to rotate, and the rotating cylinder 7 drives the motor shaft to rotate. This allows the sound sensor 15 and the vibration sensor 16 to detect the vibration and noise values ​​of the motor shaft. The above is the complete operation procedure of this device.
