Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Example: As attached Figure 1-5 As shown, a vehicle-mounted ACC static test mechanism includes a support frame 1, on which a rotatable first frame 2 and a first power device that drives the first frame 2 to rotate are installed, and the first frame 2 is connected to a rotatable second frame 3 and a second power device that drives the second frame 3 to rotate.
[0024] like Figure 1-3 As shown, in this embodiment, the first frame 2 is arranged in a U shape, and the first frame 2 includes a first bottom plate 4 and first side plates 5 located at both ends of the first bottom plate 4, and the two first side plates 5 are arranged on the same side of the first bottom plate 4 and are arranged perpendicular to the first bottom plate 4. A rotating platform 6 is arranged on the support frame, and the first bottom plate 4 is installed on the rotating platform 6. The first power device is a servo motor 29, which is connected to the rotating platform 6 to drive the first bottom plate 4 to rotate, thereby realizing the rotation of the entire first frame 2.
[0025] like Figure 2-3As shown, the support frame 1 is provided with a first photoelectric switch 7, a first origin stop block 8 and a first end stop block 9, and the first frame 2 is provided with a first detection piece 10 corresponding to the first photoelectric switch 7 and a first limit block 11 corresponding to the first origin stop block 8 and the first end stop block 9. The first photoelectric switch 7, the first origin stop block 8 and the first end stop block 9 are installed on the side of the support frame 1 close to the first frame 2, and the first detection piece 10 and the first limit block 11 are installed on the first bottom plate 4. In this embodiment, the first photoelectric switch 7 and the first origin stop block 8 are arranged along the radial direction of the rotation of the first frame 2, and the first detection piece 10 and the first limit block 11 rotate with the first frame 2. When it is necessary to return to the origin, the first detection piece 10 is located at the first photoelectric switch 7, and at this time, the first limit block 11 is located at the first origin stop block 8 and is blocked and positioned. When the first frame 2 moves, the servo motor drives the first limit block 11 to rotate to the first end stop block 9, and the first limit block 11 is located at the first end stop block 9 and is blocked and positioned. Therefore, the rotation range of the first frame 2 is the range from the first origin stopper 8 to the first end stopper 9, which is 270° in this embodiment.
[0026] like Figure 1-2 As shown, in this embodiment, the second frame 3 is arranged in a U shape, and the second frame 3 includes a second bottom plate 12 and second side plates 13 located at both ends of the second bottom plate 12. The two second side plates 13 are arranged on the same side of the second bottom plate 12 and are arranged perpendicular to the second bottom plate 12. In this embodiment, the two second side plates 13 and the two first side plates 5 are arranged in parallel, and the two second side plates 13 are fixedly connected with a rotating shaft, and the other end of the rotating shaft is connected to the corresponding first side plate 5 through a bearing. The second power device is a stepper motor 14, which is fixed on the first frame 2. The output end of the stepper motor 14 is connected to one of the rotating shafts through a synchronous belt, so that the stepper motor 14 drives the rotation of the second frame 3 through the synchronous belt.
[0027] like Figure 2 and Figure 4As shown, the first frame 2 is provided with a second photoelectric switch 15, a second origin stop block 16 and a second end stop block 17, and the second frame 3 is provided with a second detection piece 18 corresponding to the second photoelectric switch 15 and a second limit block 19 corresponding to the second origin stop block 16 and the second end stop block 17.

In this embodiment, the second detection piece 18 and the second limit block 19 rotate with the second frame 3. When it is necessary to return to the origin, the second detection piece 18 is located at the second photoelectric switch 15. At this time, the second limit block 19 is located at the second origin stop block 16 and is blocked and positioned. When the second frame 3 moves, the stepper motor 14 drives the second limit block 19 to rotate to the second end stop block 17, and the second limit block 19 is located at the second end stop block 17 and is blocked and positioned. Therefore, the rotation range of the second frame 3 is the range from the second origin stopper 16 to the second end stopper 17, which is 180° in this embodiment.
[0028] like Figure 1-2 As shown, in this embodiment, two third side panels 20 are fixedly connected to the second bottom plate 12, and the two third side panels 20 are arranged on the same side of the second bottom plate 12 and are arranged perpendicular to the second bottom plate. In this embodiment, one end of the two third side panels 20 away from the second bottom plate is fixedly connected to the tooling 21. The tooling 21 is arranged parallel to the second bottom plate 12.
[0029] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the tooling 21 is provided with two workstations for installing products, and two products can be tested at one time. An inclinometer 22 is installed on the tooling 21, and the bottom surface of the inclinometer 22 is horizontally fixed to the test tooling 21. The inclinometer 22 is used for directional horizontal calibration. A pressure head 23 that can approach or move away from the tooling 21 is provided above the tooling 21. The pressure head 23 is used to fix the product in the tooling 21. The pressure head 23 is connected to a third power device that drives it to move. A detection head 24 for detecting the product is provided on the side of the tooling 21. The detection head 24 is connected to a fourth power device that drives it to approach or move away from the product. In this embodiment, the third power device is a third cylinder 25, and the fourth power device is a fourth cylinder 26. The fourth cylinder 26 is fixed on the second base plate 12.

[0030] During testing, the servo motor drives the rotating platform, and the first frame is at the origin. The stepper motor drives the synchronous belt, and the second frame is at the origin. The servo motor drives the rotating platform, driving the first frame to rotate clockwise to a horizontal position, so that the product can be placed in the test station. The third cylinder 25 extends, the fourth cylinder 26 extends, the pressure rod and the probe head are in the avoidance position, and the vehicle-mounted product is automatically placed in the test fixture 21. The third cylinder 25 rotates to press down the product, the fourth cylinder 26 retracts, and the probe head contacts the vehicle-mounted PIN pin for testing. The equipment runs automatically according to Figure 6 Product XYZ arrow direction rotation:
[0031] In the X direction, the servo motor drives the rotating platform to rotate 90 degrees counterclockwise so that the product's X arrow points downward, and then rotates 180 degrees clockwise so that the product's arrow points upward, and finally returns to the horizontal loading and unloading position.
[0032] In the Y direction, the stepper motor drives the synchronous belt to rotate 90 degrees counterclockwise so that the Y arrow of the product points upward, and the servo motor drives the rotating platform to rotate 180 degrees clockwise so that the arrow of the product points downward, and finally returns to the horizontal loading and unloading position.
[0033] In the Z direction, the product's Z arrow points upward, and the stepper motor drives the synchronous belt to rotate 180 degrees counterclockwise, so that the product's Z arrow points downward, and finally returns to the horizontal loading and unloading position.
[0034] After the equipment is finished running, it rotates to the horizontal direction to unload. According to the test results, it automatically identifies the defective products, and the qualified products enter the next station. The defective products are automatically discharged and recycled again for the next round of static testing. The rotation angle, rotation direction, and automatic testing can be realized. The angle, direction, and speed are easy to debug, and the horizontal calibration is automatic.
