[0018] (III) Beneficial Effects

[0019] This utility model provides a clamping mechanism for an anti-deviation lifting platform used in an automotive painting production line, which has the following advantages:

[0020] 1. The anti-deviation lifting platform clamping mechanism of this automotive painting production line, through the setting of adjustment components, rotation components, and limit posts, allows the first and second motors to be started respectively according to the width of the car body or the clamping height. This causes the positive and negative threaded rods to move the moving parts, and the screw rods to adjust the height of the lifting parts, clamping the car. The limit posts are then loosened, allowing the rotating shaft to rotate within the fixed tube, adjusting the clamping angle. This achieves the effect of clamping the car and preventing shaking, avoiding potential deviations that may occur during lifting or painting when the car body is large, thus helping to ensure stability during the lifting or painting process.

[0021] 2. The anti-deviation lifting platform clamping mechanism used in this automotive painting production line, through the setting of buffer components and elastic pads, ensures that when the moving clamping plate clamps the car body, upon contact with the car body and during lifting and moving, the damping hydraulic rod is subjected to external force, causing the inner rod to retract inward. The internal piston drives the fluid flow, and the resistance generated during the fluid flow slows down the piston's movement speed, reducing the impact force caused by the movement of the clamping plate or lifting and moving. The elastic pad protects the car body surface, while the buffer spring stores elastic potential energy, allowing it to return to its original shape when the force ends, which helps to improve the protective performance of the clamping mechanism.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4This utility model provides a technical solution: a clamping mechanism for an anti-deviation lifting platform in an automotive painting production line, comprising a platform plate 1 and a control device 2. Two adjusting components 3 are fixedly connected to one side of the platform plate 1. Two moving parts 4 are threadedly connected to the surface of the adjusting components 3. A support frame 5 is fixedly connected to the top of each of the two moving parts 4. An adjusting component 6 is fixedly connected to the top of the support frame 5. A lifting component 7 is threadedly connected to the surface of the adjusting component 6. A fixing pipe 8 is fixedly connected to one side of the lifting component 7. A rotating component 9 is rotatably connected inside the fixing pipe 8. A connecting piece 10 is provided on one side of the rotating component 9. A buffer component 11 is fixedly connected to one side of the connecting piece 10. A clamping plate 12 is fixedly connected to one side of the buffer component 11.

[0029] Adjustment component 3 includes a first motor 301 and a positive and negative threaded rod 302;

[0030] Adjustment component 6 includes a second motor 601 and a lead screw 602;

[0031] The rotating assembly 9 includes a rotating shaft 901 and a rotating rod 902. By adjusting the assembly 3, adjusting the assembly 6, rotating the assembly 9, and setting the limiting post 13, the first motor 301 and the second motor 601 can be started respectively according to the width of the car body or the clamping height during use. The positive and negative threaded rod 302 moves the moving part 4, and the screw 602 adjusts the height of the lifting part 7 to clamp the car. The limiting post 13 is then loosened so that the rotating shaft 901 can rotate within the fixed tube 8 to adjust the clamping angle, thereby clamping the car and preventing it from shaking. This avoids the possibility of displacement during lifting or painting when the car body is large, and helps to ensure the stability during lifting or painting.

[0032] The buffer assembly 11 includes a damping hydraulic rod 1101 and a buffer spring 1102. With the buffer assembly 11 and the elastic pad 14, when the clamping plate 12 moves to clamp the vehicle body, the damping hydraulic rod 1101 is subjected to external force after contact with the vehicle body and during lifting and lowering. The inner rod retracts inward, and the internal piston drives the fluid to flow. The resistance generated during the fluid flow slows down the speed of the piston movement, thereby reducing the impact force caused by the movement of the clamping plate 12 or the lifting and lowering movement. The elastic pad 14 protects the surface of the vehicle body, and the buffer spring 1102 stores elastic potential energy. When the force ends, it returns to its original shape, which helps to improve the protective performance of the clamping mechanism.

[0033] The adjustment component 3 includes a first motor 301 fixedly connected to one side of the platform plate 1. The output end of the first motor 301 is splinedly connected to a transmission rod, and one end of the transmission rod is fixedly connected to a positive and negative threaded rod 302. By setting the adjustment component 3, it can adapt to different cars.

[0034] The adjustment component 6 includes a second motor 601 fixedly connected to the top of the support frame 5. The output end of the second motor 601 is splinedly connected to a transmission rod, and one end of the transmission rod is fixedly connected to a lead screw 602. The adjustment component 6 is used to adjust the height of the clamping plate 12.

[0035] The rotating assembly 9 includes a rotating shaft 901 rotatably connected inside the fixed tube 8. One end of the rotating shaft 901 is fixedly connected to a rotating rod 902, and one end of the rotating rod 902 is fixedly connected to the connecting piece 10. The rotating assembly 9 serves to adjust the angle of the clamping mechanism.

[0036] A limiting hole is provided on the top surface of the fixed pipe fitting 8. A limiting post 13 is connected to the internal thread of the limiting hole. The limiting post 13 is used to fix the rotating rod 902. The setting of the fixed pipe fitting 8 plays the role of allowing the rotating rod 902 to rotate inside.

[0037] The buffer assembly 11 includes a damping hydraulic rod 1101 fixedly connected to one side of the connecting piece 10. A buffer spring 1102 is sleeved on the surface of the damping hydraulic rod 1101. The buffer assembly 11 is designed to prevent excessive clamping force from damaging the vehicle body.

[0038] An elastic pad 14 is fixedly connected to one side of the clamping plate 12. The elastic pad 14 is made of rubber and serves to protect the car body.

[0039] In this invention, the working steps of the device are as follows:

[0040] First step: When in use, depending on the width of the car body or the clamping height, the first motor 301 and the second motor 601 can be started respectively, so that the positive and negative threaded rod 302 moves the moving part 4, and the screw 602 moves the lifting part 7 to adjust the height, clamping the car, and loosening the limit post 13, so that the rotating shaft 901 can rotate in the fixed tube 8 to adjust the clamping angle.

[0041] The second step: During use, the moving clamping plate 12 clamps the vehicle body. Upon contact with the vehicle body, and during lifting and lowering, the damping hydraulic rod 1101 is subjected to external force, causing the inner rod to contract inward. The internal piston drives the fluid flow, and the resistance generated during the fluid flow slows down the piston's movement, reducing the impact force caused by the movement of the clamping plate 12 or the lifting and lowering movement. The elastic pad 14 protects the surface of the vehicle body, while the buffer spring 1102 stores elastic potential energy, returning to its original shape when the force ends. It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model.
