[0016] Please see Figure 1-4This utility model provides a technical solution: a gripper mechanism for an overhead suspended vehicle frame tilting machine, including a gripping frame 1, a tilting frame 2, a bracket 3, and a lifting pressure frame 4. A first motor 5 is arranged on the outside of the gripping frame 1. The output shaft of the first motor 5 passes through the gripping frame 1 and is equipped with a drive gear 6. The gripping frame 1 is also equipped with a driven gear 7 through a support shaft. The driven gear 7 meshes with the drive gear 6. The tilting frame 2 is connected to the inside of the driven gear 7. A second motor 8, a guide rail 9, and a first lead screw 10 are vertically arranged on the inside of the tilting frame 2. A first lead screw seat 26 is provided at both the top and bottom of the tilting frame 2. The two ends of the first lead screw 10 are respectively connected to the first lead screw seat 26 at the top and bottom of the tilting frame 2. This structure ensures the stability of the first lead screw 10. The output shaft of the second motor 8 faces upward and is equipped with a drive sprocket 11. The top of the first lead screw 10 is equipped with a driven sprocket 12. The drive sprocket 11 and the driven sprocket 12 are connected by a chain 13. The bottom of the tilting frame 2 is equipped with a bracket 3. Side baffles 14 are provided on both sides of the bracket 3. Several reinforcing plates 15 are provided at the bottom of the bracket 3. One side of the lifting pressure frame 4 is slidably connected to the guide rail 9 through a first slider 16. The lifting pressure frame 4 also cooperates with the first lead screw 10 through a lead screw nut pair. The top of the clamping frame 1 is equipped with a second slider 25 to cooperate with the track at the bottom of the overhead suspension frame tilting machine frame, thereby realizing the lateral movement of the clamping frame 1. The lifting pressure frame 4 has guide grooves 17 on both sides. Two reinforcing plates 18 are provided on the upper surface of the lifting pressure frame 4. Guide rods 19 are provided on the outer sides of the reinforcing plates 18. A bidirectional steering box 20 is provided on the upper surface of the lifting pressure frame 4 between the two reinforcing plates 18. A third motor 21 is provided on the upper surface of the bidirectional steering box 20. The output shaft of the third motor 21 is connected to the input shaft of the bidirectional steering box 20, so that the two output shafts of the bidirectional steering box 20 are rotated by the third motor 21, thereby driving the rotation of the two second lead screws 22, and thus realizing the movement of the slide 23. The output shaft faces both sides and is connected to the second lead screw 22 via couplings. The second lead screw 22 is connected to the slide block 23 via a lead screw nut pair. Both ends of the lifting pressure frame 4 are provided with second lead screw seats 27. The outer end of the second lead screw 22 is connected to the corresponding second lead screw seat 27. This structure ensures the stability of the second lead screw 22. The reinforcing plate 18 is provided with a bearing seat 28. The second lead screw 22 is also connected to the bearing seat 28 to further ensure the stability of the second lead screw 22. The slide block 23 is guided and engaged with the corresponding guide rod 19. The slide block 23 is also movably disposed in the corresponding guide groove 17. The bottom of the slide block 23 is provided with a clamping plate 24.

[0017] Working method and operating principle: First, the two clamping frames 1 are slidably connected to the bottom rail of the overhead suspension frame tilting machine via the second slider 25, and driven by the lead screw pair and motor to make the clamping frames 1 slide along the bottom of the overhead suspension frame tilting machine. When the two clamping frames 1 are close together, they clamp the two ends of the frame. At this time, the two ends of the frame are supported on the corresponding support plates. Then, the second motor 8 is started. The second motor 8 drives the driven sprocket 12 to rotate through the drive sprocket 11 and chain 13, thereby realizing the rotation of the first lead screw 10. This causes the lifting pressure frame 4 to descend along the guide rail 9, thereby pressing it against the upper surface of the frame end. Then, the third motor 21 is started. The third motor 21 drives the two second lead screws 22 to rotate through the bidirectional steering box 20, thereby causing the slide 23 to move towards the middle along the guide groove 17 and guide rod 19. The clamping plate 24 on the lower surface of the slide 23 clamps the two sides of the top of the frame, completing the clamping of the frame end. Next, the first motor 5 is started, which drives the drive gear 6 to rotate. Through the cooperation of the drive gear 6 and the driven gear, the tilting frame 2 is tilted, thereby realizing the tilting of the frame. This utility model has a reasonable structure. The lifting pressure frame 4 can be raised and lowered along the guide rail 9 through the cooperation of the first lead screw 10. Inside the lifting pressure frame 4, there are two second lead screws 22 through the bidirectional steering box 20. Through the cooperation of the two second lead screws 22 and the slides 23, the two slides 23 can be moved closer and further apart. When the lifting pressure frame 4 presses down on the frame and clamps the end of the frame between the pallet and the lifting pressure frame 4, the top of the frame can also be clamped by the two slides 23 and the clamping plate 24, thereby ensuring the stability of the frame during the tilting of the frame and preventing the frame from slipping, thus improving safety. Several reinforcing plates 15 are provided on the lower surface of the pallet, and two reinforcing upright plates 18 are provided inside the lifting pressure frame 4, thereby greatly improving the structural strength of the pallet and the lifting pressure frame 4, and further improving the stability when clamping the frame.
