[0017] In order to deepen the understanding of the present utility model, the following will further describe the present utility model in detail in combination with embodiments. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0018] According to Figure 1 , Figure 2 , Figure 3As shown in the figure, this embodiment provides a fixture for an automotive stabilizer bar assembly with an automatic centering function, including a fixture table 1, a control box 2, a pneumatic centering mechanism, a centering limit mechanism, and a clamping mechanism. The control box 2 is fixedly arranged on the front side of the fixture table 1. The pneumatic centering mechanism includes a cylinder 3, a longitudinal push rod 4, a first limit sleeve 5, an articulated connecting rod 6, a transverse push rod 7, a second limit sleeve 8, and a centering top block 9. The cylinder 3 is fixedly arranged in the middle of the rear side of the fixture table 1, and the telescopic end of the cylinder 3 is fixedly provided with the longitudinal push rod 4. The first limit sleeve 5 is fixedly arranged in the middle of the rear side of the fixture table 1. The two sides of the rear end of the longitudinal push rod 4 are symmetrically and hingedly connected with the articulated connecting rod 6. The outer side of the articulated connecting rod 6 is correspondingly and hingedly connected with the transverse push rod 7. The second limit sleeves 8 are symmetrically and fixedly arranged on both sides of the rear upper part of the fixture table 1. The end of the transverse push rod 7 is correspondingly fixedly provided with the centering top block 9. The centering limit mechanisms are symmetrically arranged on both sides of the rear upper part of the fixture table 1. The clamping mechanism is arranged in the middle of the front side of the fixture table 1. The fixture table 1 is electrically connected to the control box 2. The front end of the longitudinal push rod 4 longitudinally slides through the first limit sleeve 5. When centering, the control box 2 is used to control the cylinder 3 to be powered on and started to push out the longitudinal push rod 4. When the longitudinal push rod 4 is pushed out, it slides along the first limit sleeve 5. When the longitudinal push rod 4 is pushed out, it drives the articulated connecting rod 6 to rotate and unfold by hinge. The articulated connecting rod 6 is used to push the transverse push rods 7 to move outwards to both sides respectively. The transverse push rods 7 drive the centering top blocks 9 to move synchronously to cooperate with the outer fixing blocks 14 to perform centering detection on the automotive stabilizer bar clamp. When the centering top blocks 9 and the outer fixing blocks 14 cannot accurately hold the clamp at the end of the automotive stabilizer bar, it indicates that the assembly symmetry of the clamp has shifted.

[0019] A plurality of groups of the second limit sleeves 8 are symmetrically fixed. The transverse push rod 7 transversely slides through the second limit sleeve 8. When the transverse push rod 7 is pushed out, it slides along the second limit sleeve 8 to maintain stability.

[0020] The centering limit mechanism includes an inner fixing seat 10, a chute 11, a first slider 12, an outer fixing seat 13, and an outer fixing block 14. The inner fixing seats 10 are symmetrically and fixedly arranged on the rear side of the fixture table 1. The chutes 11 are correspondingly opened on the inner fixing seats 10. The bottom of the centering top block 9 is correspondingly fixedly provided with the first slider 12. The first slider 12 slides in cooperation with the chute 11. The centering top block 9 and the inner fixing seat 10 are corresponding in the up and down positions. When the transverse push rod 7 drives the centering top block 9 to move, the first slider 12 and the chute 11 cooperate to guide the stable sliding of the centering top block 9. The centering top block 9 and the outer fixing block 14 cooperate to clamp the automotive stabilizer bar clamp, and centering is performed by using the thrust generated by the centering top block 9.

[0021] The clamping mechanism includes a fixed table 15, a slide rail 16, a second slider 17, a clamping table 18, a first semi-circular fixing ring 19, a fixture 20 and a second semi-circular fixing ring 21. On the front side of the fixture table 1, the fixed tables 15 are symmetrically and fixedly arranged. The slide rail 16 is fixedly arranged on the fixed table 15 in a matching manner. The second slider 17 is slidably arranged on the slide rail 16. Above the second sliders 17, the clamping table 18 is fixedly arranged. The first semi-circular fixing rings 19 are symmetrically and fixedly arranged on the clamping table 18. The fixtures 20 are symmetrically and fixedly arranged on the rear side of the clamping table 18. The second semi-circular fixing ring 21 is fixedly arranged above the fixture 20. The top of the fixture 20 is hinged and rotatable. The first semi-circular fixing ring 19 and the second semi-circular fixing ring 21 are corresponding in the up-and-down position. When performing the centering detection, according to the model of the automotive stabilizer bar, the clamping table 18 and the second slider 17 are pushed to adjust to a suitable position along the slide rail 16 to facilitate quick placement and installation for the centering detection. After placing the automotive stabilizer bar, the fixture 20 is rotated to drive the first semi-circular fixing ring 19 and the second semi-circular fixing ring 21 to merge, so as to clamp and limit the automotive stabilizer bar.

[0022] When the automotive stabilizer bar assembly fixture with an automatic centering function is performing detection, the middle of the automotive stabilizer bar is placed inside the first semi-circular fixing ring. The fixture is hinged and rotated to drive the second semi-circular fixing ring to rotate and merge to clamp the automotive stabilizer bar. When performing the detection, the cylinder is controlled by the control box to be electrified and started to push the longitudinal push rod to slide out along the first limiting sleeve. While the longitudinal push rod is moving, it drives the articulated connecting rod to be articulated and unfolded, and at the same time, it pushes the transverse push rod to slide out along the second limiting sleeve. The transverse push rod drives the centering ejector block to slide out and cooperate with the outer fixing block to clamp and detect the clamp at the end of the automotive stabilizer bar. When stable clamping cannot be achieved, it can be judged that the symmetry of the clamp assembly is offset.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
