[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1-5This utility model provides a technical solution: an acceleration sensor gripping mechanism for detecting abnormal noise in a seat frame, including an X-axis cylinder 1, a support plate 5 at the end of the X-axis cylinder 1, a pneumatic gripper 6 on the support plate 5, a gripper 7 on each of the two grippers of the pneumatic gripper 6, a groove on the adjacent side of the two grippers 7, the two grooves forming a clamping cavity, a sensor sleeve 8 inside the clamping cavity, an acceleration sensor inside the sensor sleeve 8, the acceleration sensor is installed inside the sensor sleeve 8, the sensor sleeve 8 can protect the acceleration sensor, the gripper 7 is assembled on the two grippers of the pneumatic gripper 6, the two grippers 7 can automatically grip the sensor sleeve 8;

[0020] Among them, the pneumatic gripper 6 uses compressed air as power to grip or grasp the sensor sleeve 8.

[0021] The pneumatic gripper 6 is moved along the X-axis by the X-axis cylinder 1, thereby adjusting the distance between the acceleration sensor and the seat frame to be tested. The pneumatic gripper 6 can automatically grasp the sensor sleeve 8 carrying the acceleration sensor. The acceleration sensor is fixedly installed using the sensor sleeve 8. The use of the sensor sleeve 8 avoids damage to the acceleration sensor caused by the pneumatic gripper 6 directly grasping it.

[0022] Among them, the support plate 5 is provided with an elastic compensation component 9 at the position corresponding to the pneumatic gripper 6. The pneumatic gripper 6 is installed on the support plate 5 through the elastic compensation component 9. The installation of the pneumatic gripper 6 on the support plate 5 through the elastic compensation component 9 can play a buffering role.

[0023] The output end of the X-direction cylinder 1 is provided with an L-shaped bracket 4. One end of the support plate 5 is fixedly installed on the L-shaped bracket 4. The long side of the L-shaped bracket 4 is parallel to the X-direction cylinder, and the short side of the L-shaped bracket 4 is parallel to the support plate 5. The support plate 5 is installed on the short side of the L-shaped bracket 4.

[0024] The X-axis cylinder 1 has a slide rail 2 on its back, and a slide block 3 is slidably mounted on the slide rail 2. One end of the L-shaped bracket 4 is fixedly connected to the output end of the X-axis cylinder 1, and the other end of the L-shaped bracket 4 is fixedly connected to the slide block 3. The end of the long side of the L-shaped bracket 4 is connected to the slide block 3. When the X-axis cylinder 1 is working, the X-axis cylinder 1 can push the support plate 5 to move along the X direction through the L-shaped bracket 4. At the same time, the stability of the movement of the L-shaped bracket 4 is ensured by the cooperation of the slide block 3 and the slide rail 2.

The mounting plate 91 is provided with a damper 92 that passes through the support plate 5. A telescopic spring 93 is sleeved on the damper 92. One end of the telescopic spring 93 is fixedly connected to the support plate 5, and the other end of the telescopic spring 93 is fixedly connected to the end of the damper 92. During the detection process, when a collision occurs, the pneumatic gripper 6 will drive the support plate 5 to squeeze the damper 92, causing the damper 92 to contract. At the same time, the telescopic spring 93 will also contract. Then, the damper 92 and the telescopic spring 93 work together to achieve a buffering effect.

[0026] Working principle: During use, the X-axis cylinder 1 pushes the pneumatic gripper 6 to move on the X-axis, thereby adjusting the distance between the accelerometer and the seat frame to be tested. The pneumatic gripper 6 can automatically grasp the sensor sleeve 8 carrying the accelerometer. The accelerometer is fixedly installed using the sensor sleeve 8. The use of the sensor sleeve 8 avoids damage to the accelerometer caused by the pneumatic gripper 6 directly grasping it. Then, the accelerometer inside the sensor sleeve 8 detects the seat frame.
