[0002] As the foundation of the automotive industry, automotive parts are essential for its continued healthy development. During the processing and production of automotive parts, it is necessary to calibrate and inspect the parts before they leave the factory to ensure the stability of each part. Therefore, calibration devices for automotive parts are required. For example, a Chinese patent discloses an efficient calibration device for automotive parts, with application number CN201721701440.5. This calibration device has a simple and reasonable overall structural design, is compact in size, and can be used for calibration operations of various different parts' levelness, making it highly practical. However, it cannot perform automatic alignment and fixation; the automotive parts need to be manually moved to the designated position for fixation, which takes a certain amount of time.

[0023] Reference Figure 1-6This utility model embodiment provides a calibration device for automotive parts, comprising: a base 1, an electric motor 2 fixedly connected inside the base 1, a gear 3 fixedly connected to the output end of the electric motor 2, two racks 4 meshing with the outside of the gear 3, the two racks 4 being slidably connected to the base 1 through a sliding groove 5, and a clamping plate 6 fixedly connected to the outside of each of the two racks 4, the two clamping plates 6 being slidably connected to the base 1, and the two clamping plates 6 having a T-shaped structure;

[0024] Specifically, starting the first motor 2 drives the gear 3 to move the two racks 4. Each of the two racks 4 drives the corresponding clamping plate 6 to move towards the center, thereby aligning and fixing the car parts with the clamping plate 6.

[0025] A second motor 7 is fixedly connected inside the base 1. A lead screw 8 is fixedly connected to the output end of the second motor 7. A positioning plate 9 is threadedly connected to the external end of the lead screw 8. Two guide rods 16 are fixedly connected to the upper surface of the base 1. The two guide rods 16 are slidably connected to the positioning plate 9. A fixing assembly 10 is provided on the outside of the positioning plate 9. The fixing assembly 10 includes a fixing block 17. The upper surface of the fixing block 17 is fixedly connected to the positioning plate 9. A screw 18 is threadedly connected inside the fixing block 17. A limit block 19 is fixedly connected to the end of the screw 18. A detachable connection is made inside the fixing assembly 10. Plate 23, with a cylinder 11 fixedly connected to its lower surface. A pressure sensor 12 is installed inside the cylinder 11. An elastic element 13 is fixedly connected inside the cylinder 11. A calibration column 14 is fixedly connected inside the elastic element 13. The outside of the calibration column 14 is slidably connected to the cylinder 11. The top of the pressure block 15 is in contact with the pressure sensor 12. The top of the calibration column 14 is fixedly connected to the pressure block 15. An alarm light 21 is fixedly installed on the lower surface of the positioning plate 9. The alarm light 21 is electrically connected to the pressure sensor 12. The pressure sensor 12 is electrically connected to the second motor 7.

[0026] Specifically, starting the second motor 7 drives the positioning plate 9 to move downwards, causing the calibration pins 14 to pass through their corresponding punching holes. If there are any missing punching holes or incorrect positions on the automotive parts, the calibration pins 14 will be blocked, causing them to squeeze the elastic element 13. This causes the calibration pins 14 to move the pressure block 15 upwards inside the cylinder 11, thereby squeezing the pressure sensor 12. The pressure sensor 12 receives the pressure signal and transmits it to the warning light 21, causing it to sound an alarm, indicating that the automotive parts are defective.

[0027] A horizontal frame plate 20 is fixedly connected inside the base 1. The interior of the horizontal frame plate 20 is slidably connected to the clamping plate 6. A bidirectional scale 22 is provided on the lower surface of the horizontal frame plate 20. The horizontal frame plate 20 is located below the calibration column 14.

[0028] Specifically, the crossbeam 20 provides sliding support for the clamping plate 6, and the bidirectional ruler 22 is used to calibrate the dimensions of the automotive parts.

[0029] Working principle: First, the car parts are placed on the cross plate 20. Then, the first motor 2 is started, which drives the gear 3 to move the two racks 4. Each of the two racks 4 drives the corresponding clamping plates 6 to move towards the center, thereby aligning and fixing the car parts. Then, the second motor 7 is started, which drives the positioning plate 9 to move down, and the alignment pins 14 pass through the corresponding punch holes. If there are any missing punches or incorrect positions on the punch holes of the car parts, the alignment pins 14 will be blocked, thereby squeezing the elastic element 13. This causes the alignment pins 14 to drive the pressure block 15 to move upward inside the cylinder 11, thereby squeezing the pressure sensor 12. The pressure sensor 12 receives the pressure signal and transmits it to the warning light 21, which sounds an alarm, indicating that the car parts are unqualified. At the same time, the pressure sensor 12 stops the second motor 7.
