Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection, in particular to an installation structure for online motor vibration acceleration detection. Background Art
[0002] As the power source of steering products, the noise level of the motor directly affects the ride comfort of the vehicle's customers. The motor's vibration acceleration and noise level are closely related. To improve user comfort, it is essential to evaluate the motor's operating vibration acceleration before it leaves the factory.
[0003] To measure motor vibration energy, the vibration accelerometer must be in close contact with the motor. This ensures that the motor's vibration energy is transferred to the vibration accelerometer through intermolecular forces. The vibration accelerometer uses its sensing components to convert acceleration into voltage, thereby measuring the motor's own acceleration. Therefore, close contact between the vibration accelerometer and the motor is crucial for measuring motor acceleration.
[0004] See also Figure 1 In traditional motor acceleration testing, a vibration accelerometer (1) is secured to a motor (3) using specialized glue (2). This structure requires applying glue to the motor. After the sensor is positioned, pressure must be applied continuously to ensure the glue secures it to the motor. After the test, any remaining glue on the sensor and motor surfaces must be removed. Due to the complex procedures involved in traditional motor acceleration testing, this approach is difficult to implement on mass production lines.
[0005] Therefore, it is necessary to design an installation structure for online motor vibration acceleration detection, which can improve the test efficiency while ensuring the test accuracy and facilitate use on batch production lines. Summary of the Invention
[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an installation structure for online motor vibration acceleration detection, which improves test efficiency while ensuring test accuracy and is convenient for use on batch production lines.
[0007] In order to achieve the above-mentioned purpose, the utility model is an installation structure for online motor vibration acceleration detection, including a magnet tooling and a vibration acceleration sensor. The bottom of the magnet tooling has an arc mating surface that fits the surface of the motor. The vibration acceleration sensor is fixed on the top of the magnet tooling and is located directly above the center point of the arc mating surface. A notch is provided on each side of the magnet tooling, and the structure of the notch matches the end structure of the handling tooling.
[0008] The vibration acceleration sensor and the magnet fixture are fixed with screws or glue.
[0009] The arc matching surface is adsorbed on the surface of the motor.
[0010] The end structure of the handling tool is inserted into the recess.
[0011] Compared to existing technologies, this new device connects the vibration accelerometer and motor via a magnetic fixture. The motor is fixed to the top of the magnetic fixture, and the magnetic fixture adheres to the motor surface through magnetic field attraction, enabling rapid installation of the vibration accelerometer. The structure of the magnetic fixture ensures close contact with the motor surface, ensuring test accuracy. This device offers the advantages of high efficiency and simplicity, making it suitable for repeated batch use on production lines. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will now be further described with reference to the accompanying drawings.
[0017] See also Figure 2 The present invention is an installation structure for online motor vibration acceleration detection, comprising a magnet fixture 4 and a vibration acceleration sensor. The bottom of the magnet fixture 4 has an arc-shaped mating surface 41 that fits the surface of the motor 3. The arc-shaped mating surface 41 has a contoured structure that allows the magnet fixture 4 to better fit the surface of the motor 3. The vibration acceleration sensor 1 is fixed to the top of the magnet fixture 4 and is located directly above the center point of the arc-shaped mating surface 41, bringing the vibration acceleration sensor 1 closer to the motor 3, thereby ensuring measurement accuracy. A notch 42 is provided on each side of the magnet fixture 4, and the structure of the notch 42 matches the end structure 81 of the handling fixture 8.
[0018] The vibration acceleration sensor 1 and the magnet fixture 4 are fixed with screws or glue, thereby achieving pre-fixation of the vibration acceleration sensor 1 and the magnet fixture 4 .
[0019] See also Figure 3The motor 3's housing is made of aluminum, and the magnet fixture 4 securely attaches to the stator 5 (electromagnetic steel sheet) through adsorption. Because the magnet fixture 4 fits tightly against the motor 3's surface, and the vibration accelerometer 1 is pre-attached to the magnet fixture 4, when vibrations on the motor 3's surface are transmitted to the magnet fixture 4 through molecular interaction. From there, the vibration is transmitted to the vibration accelerometer 1, which then detects the acceleration through its own sensing unit.
[0020] See also Figure 4 During assembly, the end structure 81 of the handling jig 8 is inserted into the recess 42 of the magnet jig 4. With the aid of external force, the magnet jig 4 is placed on the motor 3 via the handling jig 8, with the arcuate mating surface 41 adsorbed onto the surface of the motor 3. After installation, the end structure 81 of the handling jig 8 is removed from the recess 42 of the magnet jig 4. Since the vibration acceleration sensor 1 and the magnet jig 4 are pre-attached, the assembly of the vibration acceleration sensor 1 is completed by installing the magnet jig 4.
[0021] Similarly, when removing the vibration acceleration sensor 1 from the motor 3, the end structure 81 of the handling tooling 8 is inserted into the recess 42 of the magnetic tooling 4, and then with the help of external power, the magnetic tooling 4 can be removed by the handling tooling 8, thereby completing the removal of the vibration acceleration sensor 1 from the motor 3.
[0022] This utility model connects the vibration accelerometer and motor via a magnetic fixture. The motor is fixed to the top of the magnetic fixture, and the magnetic fixture adheres to the motor surface through magnetic field attraction, enabling rapid installation of the vibration accelerometer. The structure of the magnetic fixture ensures close contact with the motor surface, ensuring test accuracy. This utility model offers the advantages of high efficiency and simplicity, making it suitable for repeated batch use on production lines.
