Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically a clamping device for automobile shell production. Background Technology

[0002] The car body, commonly referred to as the car body or shell, is an important component of a vehicle, providing protection for passengers and withstanding various forces from the external environment, such as impacts, friction, and shocks. Modern car bodies are typically made of high-strength steel and other composite materials to improve safety and durability. The production process of car bodies includes welding, gluing, and other manufacturing steps. When welding and gluing are required, the car body needs to be clamped and fixed. Traditional clamping equipment often clamps and fixes the body from both sides. After the production process on the front is completed, it needs to be manually flipped over for processing on the back side, resulting in low production efficiency. To improve this situation, a clamping device for car body production is proposed.

[0003] For example, the clamping device for processing automobile shells disclosed in the authorization announcement number CN214723557U includes a fixed box. The top of the fixed box has two rectangular holes symmetrically opened. A rectangular block is slidably installed in each of the two rectangular holes. A movable plate is fixedly installed on the top of each of the two rectangular blocks. A flip plate is rotatably installed on the top of each of the two movable plates. A pressing plate is slidably installed on the outer side of each of the two flip plates. A rubber sleeve is provided on the top of each of the two pressing plates. Two guide rods are slidably installed laterally on each of the two movable plates. One end of a pull rope is fixedly connected to each of the two guide rods.

[0004] Although it achieves convenient operation, it can not only squeeze and fix the two sides of the shell, but also squeeze and fix the top, increasing the fixing effect;

[0005] However, this does not solve the problem that existing clamping equipment is not conducive to convenient and flexible adjustment of the height and rotation of the car body for processing, nor to centering and fixing the car body, thus affecting the flexibility of clamping the car body and the convenience of production and processing. Utility Model Content

[0006] The purpose of this utility model is to provide a clamping device for automobile shell production, so as to solve the problems mentioned in the background art, which are not convenient and flexible to adjust the height and rotation of the automobile shell to adjust the processing position of the automobile shell, which is not conducive to the centering and fixing of the automobile shell, thus affecting the flexibility of clamping the automobile shell and the convenience of production and processing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for automobile shell production, comprising a placement seat and an integrated plate. The integrated plate is installed inside the placement seat. A clamping motor is installed at the center of the top of the integrated plate. A gear is installed at the output end of the clamping motor. Slider blocks are slidably installed on the tops of the integrated plate on both sides of the clamping motor. Racks are installed on the side walls of the sliders, and the racks mesh with the gears. Integrated frames are symmetrically slidably installed on the top of the placement seat, and the integrated frames are respectively connected to the racks. Lead screws are movably installed inside the integrated frames. Servo motors are installed on the tops of the integrated frames, and the output ends of the servo motors are connected to the lead screws. Threaded sleeves are fitted on the surface of the lead screws, and the threaded sleeves are threadedly connected to the lead screws. Rotary seats are installed on the side walls of the threaded sleeves.

[0008] Preferably, each of the rotating seats has a worm gear movably installed inside, and each of the rotating seats has a drive motor installed at its top, with the output end of the drive motor connected to the worm gear.

[0009] Preferably, a rotating shaft is movably installed inside the rotating seat on one side of the worm, and a worm wheel is fitted on the surface of the rotating shaft, with the worm wheel meshing with the worm.

[0010] Preferably, a bearing block is installed at the end of the rotating shaft away from the rotating seat, and two sets of grippers are symmetrically arranged on the outer wall of the bearing block.

[0011] Preferably, each of the bearing blocks is symmetrically provided with an electric push rod, and the tail of the electric push rod is movably connected to a set of grippers.

[0012] Preferably, each of the electric push rods has a push arm installed at its output end, and each push arm has a linkage shaft at the end near the other set of grippers, and the push arm is movably connected to the grippers through the linkage shaft.

[0013] Preferably, each of the grippers has a movable shaft at one end near the support block, and the grippers are movably connected to the support block through the movable shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the clamping device not only realizes the convenient and flexible adjustment of the height of the car body and the rotation adjustment of the processing position of the car body, which facilitates the centering clamping and fixing of the car body, but also improves the flexibility of clamping the car body and the convenience of production and processing.

[0015] The car body is placed on top of the mounting base. A servo motor drives a lead screw to rotate, which in turn moves a threaded sleeve. The threaded sleeve then moves a rotating base, a rotating shaft, a support block, and grippers, bringing the grippers to the height of the car body's side. A clamping motor drives a gear to rotate, which in turn moves two sets of racks towards each other. The racks then move an integrated frame, a rotating base, a rotating shaft, a support block, and grippers towards each other, bringing the grippers closer to the side of the car body. An electric push rod drives a push arm to move, which in turn drives one set of grippers to rotate around a movable shaft via a linkage shaft. The electric push rod also drives the other set of grippers to rotate around the movable shaft, causing the two sets of grippers to rotate towards each other and clamp and fix the car body, providing stable support. Afterward, the car body can be processed. This system allows for convenient and flexible adjustment to adapt to the height of the car body, facilitating center-type clamping and fixing of the car body and improving the flexibility of clamping the car body.

[0016] The drive motor rotates the worm gear, which in turn drives the rotating shaft via the worm wheel. The rotating shaft then rotates the bearing block, grippers, and car body, thus turning the back of the car body to the front. After that, the back side can be processed. If the mounting block blocks the rotation path, the height of the car body can be adjusted by controlling the servo motor, and then the car body can be rotated. This allows for convenient rotation and adjustment of the processing position of the car body, improving the convenience of car body production and processing. Attached Figure Description

A threaded sleeve 9 is fitted on the surface of the lead screw 10, and the threaded sleeve 9 is threadedly connected to the lead screw 10. A rotating seat 3 is installed on the side wall of the threaded sleeve 9.

[0025] The car body is placed on top of the placement seat 1. The servo motor 8 is turned on, which drives the lead screw 10 to rotate. With the lead screw 10 and the threaded sleeve 9 connected by threads, the lead screw 10 drives the threaded sleeve 9 to move. The threaded sleeve 9 drives the rotating seat 3, the rotating shaft 5, the bearing block 6, and the gripper 4 to move, so that the gripper 4 moves to the height of the side of the car body. Then, the clamping motor 15 is turned on, which drives the gear 16 to rotate. With the gear 16 and the rack 17 meshing with each other, and with the sliding engagement between the slider 18 and the integrated plate 7, the gear 16 drives the two sets of racks 17 to move towards each other. The racks 17 drive the integrated frame 2, the rotating seat 3, and the rotating shaft 5. The bearing block 6 and the gripper 4 move towards each other to bring the gripper 4 closer to the side of the car body. Then, the electric push rod 21 is opened, which drives the push arm 19 to move. The push arm 19 drives one set of grippers 4 to rotate around the movable shaft 20 via the linkage shaft 12. The electric push rod 21 drives another set of grippers 4 to rotate around the movable shaft 20, so that the two sets of grippers 4 rotate towards each other and clamp and fix the car body, providing stable support for the car body. Then, the relevant processing operations can be performed on the car body. This realizes convenient and flexible adjustment to adapt to the height of the car body, facilitates the centering clamping and fixing of the car body, and improves the flexibility of clamping the car body.

[0026] The rotating seat 3 has a worm gear 13 movably installed inside. The top of the rotating seat 3 is equipped with a drive motor 14, and the output end of the drive motor 14 is connected to the worm gear 13. The rotating seat 3 on one side of the worm gear 13 has a rotating shaft 5 movably installed inside. The surface of the rotating shaft 5 is fitted with a worm wheel 11, and the worm wheel 11 meshes with the worm gear 13.

[0027] A bearing block 6 is installed at the end of the rotating shaft 5 away from the rotating seat 3. Two sets of grippers 4 are symmetrically arranged on the outer wall of the bearing block 6. Electric push rods 21 are symmetrically arranged on the outside of the bearing block 6. The electric push rods 21 play a power driving role, and the tail of the electric push rods 21 is movably connected to a set of grippers 4.

[0028] Each of the output ends of the electric push rod 21 is equipped with a push arm 19. Each push arm 19 is provided with a linkage shaft 12 at the end near the other set of grippers 4. The push arm 19 is movably connected to the grippers 4 through the linkage shaft 12. Each gripper 4 is provided with a movable shaft 20 at the end near the bearing block 6. The gripper 4 is movably connected to the bearing block 6 through the movable shaft 20.

[0029] After the front of the car body is processed, the drive motor 14 is turned on, which drives the worm gear 13 to rotate. Under the mutual meshing of the worm gear 13 and the worm wheel 11, the worm gear 13 drives the rotating shaft 5 to rotate through the worm wheel 11. The rotating shaft 5 drives the bearing block 6, the gripper 4 and the car body to rotate, so as to rotate the back of the car body to the front. Then the processing work on the back can be completed. If the mounting seat 1 blocks the rotation path during rotation, the height of the car body can be adjusted by controlling the servo motor 8. Then the car body can be rotated. This realizes convenient rotation adjustment of the processing position of the car body and improves the convenience of car body production and processing.

[0030] Working principle: The car body is placed above the placement seat 1. The servo motor 8 drives the lead screw 10 to rotate, which in turn drives the threaded sleeve 9 to move. The threaded sleeve 9 then drives the rotating seat 3, rotating shaft 5, bearing block 6, and gripper 4 to move, bringing the gripper 4 to the height of the side of the car body. The clamping motor 15 drives the gear 16 to rotate, which in turn drives two sets of racks 17 to move towards each other. The racks 17 then drive the integrated frame 2, rotating seat 3, rotating shaft 5, bearing block 6, and gripper 4 to move towards each other, bringing the gripper 4 closer to the side of the car body. The electric push rod 21 drives the push arm 19 to move, which in turn drives one set of grippers 4 to rotate around the movable shaft 20 via the linkage shaft 12. The electric push rod 21 then drives the other set of grippers 4 to rotate around the movable shaft 20. The movable shaft 20 rotates to cause the two sets of grippers 4 to rotate in opposite directions and clamp and fix the car body, providing stable support for the car body. After that, the relevant processing operations can be performed on the car body. After the front of the car body is processed, the drive motor 14 drives the worm gear 13 to rotate. The worm gear 13 drives the rotating shaft 5 to rotate through the worm wheel 11. The rotating shaft 5 drives the bearing block 6, grippers 4 and car body to rotate, so that the back of the car body is rotated to the front. Then the processing operations can be completed on the back. If the mounting seat 1 blocks the rotation path during rotation, the height of the car body can be adjusted by controlling the servo motor 8. Then the car body can be rotated. The above is the complete usage of the clamping equipment used for the production of car bodies.
