Description

Technical Field

[0001] This utility model relates to the field of automotive testing technology, specifically a deformation measuring device for automotive body doors and windows. Background Technology

[0002] In the automobile production process, the torsional stiffness test of the automobile body-in-white is an important part of the static analysis of the automobile. According to relevant testing standards, the deformation of the diagonal of the doors and windows of the body-in-white needs to be measured during the torsional stiffness test.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN211855763U) discloses a deformation measuring device for doors and windows of an automobile body-in-white, comprising: a fixed rod; a sliding rod slidably sleeved on one end of the fixed rod; a first telescopic rod slidably sleeved on the other end of the fixed rod, the end of the first telescopic rod having a first clamp for clamping the edge of the door / window; a second telescopic rod slidably sleeved on the end of the sliding rod, the end of the second telescopic rod having a second clamp for clamping the edge of the door / window; and a displacement sensor disposed on the fixed rod or the sliding rod for detecting the relative sliding distance between the fixed rod and the sliding rod.

[0004] This invention, by setting two telescopic rods that are slidably sleeved in the fixed rod and the sliding rod, allows the length of the entire deformation measuring device to be quickly and adaptably changed according to the diagonal dimensions of different doors and windows, thus improving the versatility of the deformation measuring device. However, there are still many shortcomings in practical applications. When we fix the deformation measuring device to the door or window of a car body, we may encounter some minor adjustment problems, such as the device being slightly too long or too short. In this case, if we want to make a small tightening adjustment to the device, the operation process will be very cumbersome and inconvenient, which can easily have an adverse effect on the measurement accuracy of the displacement sensor, thereby greatly reducing the accuracy and reliability of the measurement results.

[0005] Therefore, this utility model provides a deformation measuring device for automobile body doors and windows to solve the above problems. Utility Model Content

Detailed Implementation

[0017] This utility model provides a deformation measuring device for automobile body doors and windows, such as... Figure 1-5 As shown, the deformation measuring device for automobile body doors and windows includes a displacement sensor 1 and two round rods 4. The displacement sensor 1 has round rods 2 installed on its left and right sides, and extension blocks 6 are fixedly connected to the outer surfaces of the two round rods 2. Both round rods 24 have extension blocks 15 fixedly connected to their outer surfaces. A rotating ring 21 is rotatably connected inside the extension block 15. A threaded rod 3 is threadedly connected inside the rotating ring 21. The outer surface of the threaded rod 3 is slidably connected to the inside of the round rod 24. Four limiting blocks 17 are fixedly connected to the outer surface of the threaded rod 3 on the side closest to the round rod 2. Four limiting grooves 20 are opened inside the round rod 24. The outer surface of the limiting block 17 is slidably connected to the inside of the limiting groove 20.

[0018] Specifically, by setting up a rotating ring 11 and manually turning it, the rotating ring 11 will drive the fixed block 8 to move outward or inward through the threaded rod 3. This movement process can then precisely adjust the position of the clamping plate 10. The entire operation process is relatively simple and convenient, which can not only effectively improve the connection tightness between the device and the vehicle body doors and windows, but also further improve the measurement accuracy of the displacement sensor 1, ensuring the accuracy and reliability of the measurement results.

[0019] The outer surface of the rotating ring 11 is provided with anti-slip texture. The outer surface of the threaded rod 3 away from the round rod 2 is rotatably connected to a universal ball 18. The outer surface of the universal ball 18 is fixedly connected to a fixing block 8.

[0020] Two clamping plates 10 are provided on the back of the fixing block 8. A pad 19 is fixedly connected to the opposite side of each clamping plate 10. The front of the outer clamping plate 10 is slidably connected to the inside of the fixing block 8.

[0021] The fixed block 8 has a bolt 9 internally threaded on the side away from the round rod 4. The side of the bolt 9 near the threaded rod 3 is rotatably connected to the side of the clamping plate 10 away from the threaded rod 3.

[0022] The inner surface of the first round rod 2 is slidably connected to the outer surface of the second round rod 4. The outer surface of the second extension block 6 is provided with a thread 14. The outer surface of the second extension block 6 is threadedly connected to a rotating ring 7. The outer surface of the rotating ring 7 is provided with anti-slip texture 2. A guide ring 13 is fixedly connected to the side of the rotating ring 7 away from the displacement sensor 1.

[0023] The guide ring 13 has two wedge blocks 16 inside, and each of the two wedge blocks 16 is fixedly connected to a connecting block 15 on the side of the round rod 2.

[0024] A clamping ring 12 is fixedly connected to the side of the connecting block 15 near the round rod 2, and the outer surface of the connecting block 15 is slidably connected to the inside of the round rod 2.

[0025] By setting the rotating ring 7 and turning it, the rotating ring 7 drives the guide ring 13 to move outward. Due to the inclined surface design inside the guide ring 13, when the guide ring 13 moves to the left, it will drive the connecting block 15 to slide into the round rod 2 through the wedge block 16. The connecting block 15 drives the clamping ring 12 to clamp the round rod 2. At this time, the round rod 2 is fixed. Make a rough adjustment to the size of the device, and then fix the device to the car door window through the clamping plate 10. Finally, make a fine adjustment by turning the rotating ring 11 to drive the threaded rod 3 to move. The threaded rod 3 drives the fixing block 8 to make a fine adjustment through the universal ball 18. After the final adjustment, test it.
