[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 5 As shown in this embodiment, an automotive parts lifting fixture includes a crossbeam 1. Two upper rotating seats 2 are symmetrically arranged on the front and rear sides of the crossbeam 1. An upper rotating plate 3 is rotatably connected inside the two upper rotating seats 2. A guide groove 4 is opened inside the upper rotating plate 3. A lower rotating plate 5 is rotatably connected to the bottom of the upper rotating plate 3. A mounting block 6 is fixedly connected to the side of the lower rotating plate 5 near the crossbeam 1. A rotating block 7 is rotatably connected to the top of the mounting block 6. A sliding screw 8 is fixedly connected to the top of the rotating block 7. A positioning nut 9 is threadedly connected to the surface of the sliding screw 8.

[0023] During the closing process of gripper 13 and gripper 24, the upper rotating plate 3 and the lower rotating plate 5 rotate relative to each other, and the sliding screw 8 slides inside the guide groove 4. After gripper 13 and gripper 24 clamp the part, the positioning nut 9 is rotated so that it rotates on the surface of the sliding screw 8 and abuts against the upper rotating plate 3, thereby restricting the movement of gripper 13 and gripper 24 to improve stability during movement. The rotating block 7 at the bottom of the sliding screw 8 is connected to the mounting block 6 by connecting bolts and nuts. By controlling the number of rotations of the nut, the rotation or fixation between the rotating block 7 and the mounting block 6 can be controlled to adapt to the storage and use of the fixture.

[0024] A connecting bolt is provided between the mounting block 6 and the rotating block 7. A nut is provided on the surface of the connecting bolt to control the rotation or fixation between the rotating block 7 and the mounting block 6. The sliding screw 8 passes through the guide groove 4 and extends to the top of the upper rotating plate 3. The positioning nut 9 abuts against the upper rotating plate 3.

[0025] Two mounting seats 10 are symmetrically arranged on both sides of the bottom of the crossbeam 1. The bottom of the two mounting seats 10 is rotatably connected to a side rotating plate 11 and a side rotating plate 2 12. The bottom of the side rotating plate 11 is rotatably connected to a clamp 13, and the bottom of the side rotating plate 2 12 is rotatably connected to a clamp 2 14. The clamp 2 14 is located inside the clamp 13.

[0026] During the process of the hanging ring 28 driving the crossbeam 1 to move up and down, the side rotating plate 11 and the side rotating plate 22 rotate inside the mounting base 10. The side rotating plate 11 and the gripper 13 rotate relative to each other, and the side rotating plate 22 and the gripper 24 rotate relative to each other, thereby realizing the opening and closing of the gripper 13 and the gripper 24 to facilitate the clamping and separation of the parts.

[0027] Rubber pads 15 are fixedly connected to the sides of the grippers 13 and 14 that are close to each other, and multiple friction protrusions 16 are fixedly connected to one side of the rubber pads 15.

[0028] By setting rubber pads 15 on the first jaw 13 and the second jaw 14, direct contact with the surface of the part is avoided, thus preventing damage to the part. In addition, multiple friction bumps 16 are set on the rubber pads 15 to increase the friction between the part and the gripper, thereby improving the stability of the fixture during use.

[0029] Both gripper 13 and gripper 214 are fixedly connected to guide rods 17 on the side near the upper rotating plate 3. Guide plates 18 are provided on the surface of guide rods 17. Two moving grooves 19 are symmetrically opened inside the guide plates 18. Guide rods 17 are slidably connected inside the moving grooves 19.

[0030] A connecting plate 20 is fixedly connected to the side of the guide plate 18 away from the guide rod 17. A positioning frame 21 is fixedly connected to the top of the connecting plate 20. A fixing groove 22 is opened on the top of the positioning frame 21. Two lower rotating seats 23 are symmetrically arranged on the front and rear sides of the connecting plate 20. The two lower rotating seats 23 are rotatably connected to the lower rotating plate 5.

[0031] An adjusting seat 24 is fixedly connected to the bottom of the crossbeam 1. A connecting column 25 is rotatably connected to the bottom of the adjusting seat 24. A locking column 26 is fixedly connected to the bottom of the connecting column 25. A lifting lug 27 is fixedly connected to the top of the crossbeam 1. A hanging ring 28 is rotatably connected to the top of the lifting lug 27.

[0032] Rotate the connecting column 25 so that it rotates inside the adjusting seat 24. After it deflects to a certain angle, install the locking column 26 in the fixing groove 22 of the positioning frame 21. The connecting column 25 drives the locking column 26 to return to the vertical state. The locking column 26 is limited by the limiting plate at the bottom of the locking column 26, thereby limiting the rotation of the side rotating plate 11 and the gripper 13, and the rotation of the side rotating plate 22 and the gripper 24, so as to realize the storage of the clamp.

[0033] This utility model provides a lifting fixture for automotive parts, the specific working principle of which is as follows:

[0034] In use, rotate the nut and engage it with the connecting bolt to fix the position between the rotating block 7 and the mounting block 6. Use the hook and hanging ring 28 to lift the clamp and move it above the part, so that the part is between the first clamp 13 and the second clamp 14. Pull the hanging ring 28 upward, and the first side rotating plate 11 and the second side rotating plate 12 will rotate inside the mounting base 10. The upper rotating plate 3 and the lower rotating plate 5 will rotate accordingly. At the same time, the sliding screw 8 moves inside the guide groove 4, and the sliding rod slides in the moving groove 19 of the guide plate 18. The first clamp 13 and the second clamp 14... 14 then rotates and moves closer to the part, thereby clamping the part. Rotate the positioning nut 9 so that it rotates on the surface of the sliding screw 8 and abuts against the upper rotating plate 3, thereby restricting the movement of gripper 13 and gripper 24. After moving to the work site, the part contacts the processing table. Rotate the positioning nut 9 to release the restriction. Side rotating plate 11 and gripper 13 rotate, side rotating plate 212 and gripper 24 rotate, gripper 13 and gripper 214 separate from the part, and the operator can then remove the fixture for subsequent hoisting work.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
