[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 In this embodiment of the present invention, an automotive parts positioning and clamping mechanism includes a base plate 1. A first hydraulic oil tank 5 is fixedly connected to the center of the upper end of the base plate 1. A second hydraulic oil tank 6 is fixedly connected to the upper end of the first hydraulic oil tank 5. A support mechanism for supporting automotive parts of different shapes is provided at the upper end of the second hydraulic oil tank 6. A first electric telescopic rod 10 is vertically fixedly connected to the upper end of the base plate 1 on both sides of the first hydraulic oil tank 5. A second electric telescopic rod 11 is horizontally fixedly connected to the output end of the first electric telescopic rod 10. The output end of the second electric telescopic rod 11 faces the center of the base plate 1. A housing 12 is fixedly connected to the output end of the second electric telescopic rod 11. An adjusting clamping mechanism for adjusting the clamping position according to the surface condition of the automotive parts is provided at the end of the housing 12 away from the second electric telescopic rod 11.

[0024] The support mechanism includes several fixed frames 7 arranged in a matrix. The fixed frames 7 are vertically fixed to the upper end of the second hydraulic oil tank 6, and the lower end of the fixed frames 7 communicates with the interior of the second hydraulic oil tank 6. A piston block 17 is slidably connected to the inner wall of the fixed frame 7. A limit post 8 is vertically fixed to the upper end of the piston block 17. The end of the limit post 8 away from the piston block 17 slides through the top of the fixed frame 7 and is positioned above the fixed frame 7. A spring 16 is fixedly connected to the lower end of the piston block 17. The lower end of the spring 16 is fixedly connected to the bottom of the second hydraulic oil tank 6. The interior of the fixed frame 7 below the piston block 17 and the interior of the second hydraulic oil tank 6 are both filled with hydraulic oil. The interior of the first hydraulic oil tank 5 is not filled with hydraulic oil. The first hydraulic oil tank 5 and the second hydraulic oil tank 6 are provided with fixing components for fixing the limit post 8 after it extends or retracts.

[0025] The fixed assembly includes several electrically controlled valves 2, which are arranged around the side wall of the first hydraulic oil tank 5. A first L-shaped connecting pipe 3 and a second L-shaped connecting pipe 4 are fixedly connected to both ends of each electrically controlled valve 2. The end of the first L-shaped connecting pipe 3 away from the electrically controlled valve 2 passes through the side wall of the first hydraulic oil tank 5 and is vertically installed at the bottom of the first hydraulic oil tank 5. The first L-shaped connecting pipe 3 is sealed and fixedly connected to the side wall of the first hydraulic oil tank 5. The height of the hydraulic oil inside the first hydraulic oil tank 5 is always higher than the end of the first L-shaped connecting pipe 3 away from the electrically controlled valve 2. The end of the second L-shaped connecting pipe 4 away from the electrically controlled valve 2 passes through the side wall of the second hydraulic oil tank 6 and is vertically installed at the bottom of the second hydraulic oil tank 6. The second L-shaped connecting pipe 4 is sealed and fixedly connected to the side wall of the second hydraulic oil tank 6. A controller 9 for controlling the electrically controlled valves 2 is fixedly connected to the upper end of the base plate 1.

[0026] In use, the operator controls the electric valve 2 to open via the controller 9. Then, the operator places the automotive parts on the upper end of the limiting post 8. The parts contact the limiting post 8 and apply pressure. Under the pressure, the limiting post 8 pushes the piston block 17 to move downward within the fixed frame 7. The piston block 17 compresses the spring 16 and presses the hydraulic oil in the second hydraulic oil tank 6 into the first hydraulic oil tank 5 through the second L-shaped connecting pipe 4, the electric valve 2, and the first L-shaped connecting pipe 3. This allows the limiting post 8 to adaptively rise and fall according to the surface shape of the parts, forming initial support.

[0027] Once the parts are placed stably, the controller 9 closes the electronically controlled valve 2, cutting off the hydraulic oil passage between the first hydraulic oil tank 5 and the second hydraulic oil tank 6. At this time, the limit post 8 can no longer move, and the support surface is locked, ensuring that the parts will not be displaced during processing.

[0028] The adjusting clamping mechanism includes a clamping block 15. Two motors 18 are fixedly connected inside the housing 12. The two motors 18 are arranged side by side. The output end of the motor 18 faces the center of the base plate 1. The output end of the motor 18 is fixedly connected to a swing plate 13 through the side wall of the housing 12. The swing plate 13 is perpendicular to the output shaft of the motor 18. A third electric telescopic rod 14 is fixedly connected to the end of the swing plate 13 away from the motor 18. The third electric telescopic rod 14 is parallel to the output shaft of the motor 18. The clamping block 15 is fixedly connected to the output end of the third electric telescopic rod 14.

[0029] In use, the vertical and horizontal positions of the housing 12 are controlled by the first electric telescopic rod 10 and the second electric telescopic rod 11 respectively, so that it is close to the parts. Then, the motor 18 is started to drive the swing plate 13 to rotate. The swing plate 13 drives the third electric telescopic rod 14 and the clamping block 15 to rotate, thereby adjusting the position of the clamping block 15 so that the clamping block 15 can fully fit with the surface of the parts. Then, the third electric telescopic rod 14 is started to push the clamping block 15 to clamp and fix the surface of the automotive parts.

[0030] Working principle of an automotive parts positioning and clamping mechanism:

[0031] In use, the operator controls the electric valve 2 to open via the controller 9. Then, the operator places the automotive parts on the upper end of the limiting post 8. The parts contact the limiting post 8 and apply pressure. Under the pressure, the limiting post 8 pushes the piston block 17 to move downward within the fixed frame 7. The piston block 17 compresses the spring 16 and presses the hydraulic oil in the second hydraulic oil tank 6 into the first hydraulic oil tank 5 through the second L-shaped connecting pipe 4, the electric valve 2, and the first L-shaped connecting pipe 3. This allows the limiting post 8 to adaptively rise and fall according to the surface shape of the parts, forming initial support.

[0032] Once the parts are placed stably, the controller 9 closes the electronically controlled valve 2, cutting off the hydraulic oil passage between the first hydraulic oil tank 5 and the second hydraulic oil tank 6. At this time, the limit post 8 can no longer move, and the support surface is locked, ensuring that the parts will not be displaced during processing.

[0033] Then, the vertical and horizontal positions of the housing 12 are controlled by the first electric telescopic rod 10 and the second electric telescopic rod 11 respectively, so that it is close to the parts. Then, the motor 18 is started to drive the swing plate 13 to rotate. The swing plate 13 drives the third electric telescopic rod 14 and the clamping block 15 to rotate, thereby adjusting the position of the clamping block 15 so that the clamping block 15 can fully fit with the surface of the parts. Then, the third electric telescopic rod 14 is started to push the clamping block 15 to clamp and fix the surface of the automotive parts.

[0034] After processing, the clamping mechanism is released, the workers remove the car parts, and then the electronically controlled valve 2 is reopened. The spring 16 pushes the piston block 17 and the limit post 8 to reset, and the hydraulic oil inside the first hydraulic oil tank 5 is drawn back into the second hydraulic oil tank 6 through the first L-shaped connecting pipe 3, the electronically controlled valve 2, and the second L-shaped connecting pipe 4.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
