[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 and Figure 2The utility model provides an embodiment of an automatic positioning and clamping device, comprising a lifting plate 1, the top of the lifting plate 1 is fixedly connected to a clamping base 2, the top of the clamping base 2 is provided with four moving grooves 3, the bottom of the lifting plate 1 is fixedly connected to a motor 4, the output end of the motor 4 is fixedly connected to a turntable 5, the inner wall of the clamping base 2 is fixedly connected to four limit plates 6, the outside of the four limit plates 6 are slidably connected to a slider 7, a connecting rod 8 is provided between the slider 7 and the turntable 5, the top of the four sliders 7 are fixedly connected to the clamping plate 9, two slide grooves 2 19 are provided on the right side of the bottom of the lifting plate 1, and a lifting assembly is provided at the bottom of the lifting plate 1 for adjusting the height of the clamping base 2, the outer side of the clamping plate 9 is slidably connected to the inside of the moving groove 3, one end of the connecting rod 8 is rotatably connected to the outside of the slider 7, and the other end of the connecting rod 8 is rotatably connected to the outside of the turntable 5, and the bottom of the slider 7 is slidably connected to the inner bottom wall of the clamping base 2.

[0031] Specifically, the lifting platform 1 serves as the supporting structure for the entire device. It moves up and down via a lifting assembly at its base, adjusting the height of the clamping base 2 to accommodate operators of varying heights or workpiece positioning requirements. The clamping base 2, located atop the lifting platform 1, secures and supports the workpiece. Four movable slots 3 on its top provide a track for the movement of the clamping plate 9, ensuring its stability and precision during clamping. A motor 4, serving as the power source, drives the entire system through a turntable 5 connected to its output terminal. The operation of the motor 4 drives the turntable 5 to rotate, and then through the linkage of the connecting rod 8 and the slider 7, the clamping plate 9 moves in the moving groove 3 to achieve clamping and release of the workpiece. The limit plate 6 is set on the inner wall of the clamping base 2. The limit plate 6 provides a limited track for the movement of the slider 7 to ensure that the slider 7 maintains linear motion during the movement process, thereby improving the accuracy of the movement of the clamping plate 9. The slider 7 moves in a straight line under the guidance of the limit plate 6. It is connected to one end of the connecting rod 8 and is driven by the rotation of the connecting rod 8 to move the clamping plate 9 to achieve clamping or release of the workpiece. The clamping plate 9 slides in the moving groove 3 through the movement of the slider 7, thereby achieving clamping and release of the workpiece. The design of the outer sliding connection inside the moving groove 3 ensures the stability and flexibility of the clamping plate 9 during the movement. One end of the connecting rod 8 is connected to the slider 7, and the other end is connected to the turntable 5. The linkage between the slider 7 and the turntable 5 is achieved through the drive of the motor 4, thereby controlling the movement of the clamping plate 9 to complete the clamping operation of the workpiece. The lifting assembly is a key component for adjusting the height of the clamping base 2. The lifting assembly adapts to the height positioning of the workpiece with different requirements through the up and down movement of the lifting plate 1, ensuring the flexibility and applicability of the operation.

[0032] Reference Figure 1 and Figure 3The lifting assembly includes two sliders 10, the outer side of the slider 2 10 is slidably connected to the inside of the slide groove 2 19, a bottom plate 11 is provided under the lifting plate 1, and two slide grooves 12 are provided on the top right side of the bottom plate 11. A fixed plate 14 is fixedly connected to the top left of the bottom plate 11, and a cylinder 15 is fixedly connected to the top of the bottom plate 11. The output end of the cylinder 15 is fixedly connected to the movable plate 16, and the front and rear sides of the bottom of the movable plate 16 are fixedly connected to sliders 3 13. A connecting rod 17 is provided between the lifting plate 1 and the movable plate 16, and a connecting rod 2 18 is provided between the fixed plate 14 and the slider 2 10. The outer side of the slider 3 13 is slidably connected to the inside of the slide groove 12, and the bottom of the movable plate 16 is slidably connected to the top of the bottom plate 11. One end of the connecting rod 2 18 is rotatably connected to the bottom of the slider 2 10, and the other end of the connecting rod 2 18 is rotatably connected to the top of the fixed plate 14. One end of the connecting rod 17 is rotatably connected to the bottom of the lifting plate 1, and the other end of the connecting rod 17 is rotatably connected to the top of the movable plate 16.

[0033] Specifically, the outer side of the slider 2 10 slides inside the chute 2 19 and is connected to both ends of the connecting rod 2 18. Driven by the cylinder 15, it moves up and down along the chute 2 19, driving the vertical movement of the entire lifting assembly to adjust the height of the clamping base 2. As the basic support structure of the lifting assembly, the cylinder 15 is fixedly connected to the top of the base plate 11, providing a platform for the installation and operation of the cylinder 15. At the same time, the chute 12 on the right side of the top of the base plate 11 provides guidance for the movement of the slider 3 13, ensuring the linearity of the movement. The fixed plate 14 is fixedly connected to the left side of the top of the base plate 11 and is connected to the slider 2 10 and the other end of the connecting rod 2 18, providing a fixed support point to ensure the stability and guidance of the entire lifting assembly. The cylinder 15 acts as a driving device, driving the entire lifting assembly up and down through the moving plate 16 connected to the output end. The driving force of the cylinder 15 can accurately control the movement of the movable plate 16 and the connecting rod 2 18 to achieve the adjustment of the height of the clamping base 2. The movable plate 16 is driven by the cylinder 15 to move up and down, and the front and rear sides of its bottom are connected with sliders 3 13. The movement of the movable plate 16 is driven by the sliding of the slider 3 13 in the slide groove 12, driving the entire lifting assembly to move up and down. The outer side of the slider 3 13 slides inside the slide groove 12 and is connected to the bottom of the movable plate 16. The movement of the connecting rod 17 and the connecting rod 2 18 is driven by its movement. One end of the connecting rod 17 is connected to the bottom of the lifting plate 1, and the other end is connected to the top of the movable plate 16. The up and down movement of the movable plate 16 drives the lifting plate 1 to move up and down, thereby adjusting the height of the clamping base 2. One end of the connecting rod 2 18 is connected to the bottom of the slider 2 10, and the other end is connected to the top of the fixed plate 14. The up and down movement of the slider 2 10 drives the movement of the fixed plate 14 and the connecting rod 2 18, further adjusting the position of the entire lifting assembly.

[0034] Working principle: When it is necessary to adjust the height of the clamping base 2 according to the height of different workers, start the cylinder 15 to pull the movable plate 16 to move. The movement of the movable plate 16 drives the slider three 13 to slide inside the slide groove 12, and at the same time pushes the connecting rod 17 and the connecting rod 2 18 to rotate upward, thereby causing the lifting plate 1 to move upward. At this time, the slider 2 10 on the connecting rod 2 18 will slide in the slide groove 2 19. When it reaches the appropriate position, the driving cylinder 15 is stopped to complete the adjustment. When it is necessary to position and clamp workpieces of different sizes, first place the workpiece between the four clamping plates 9, start the motor 4 to drive the turntable 5 to rotate, so that the connecting rod 8 is tightened toward the middle, and the slider 1 7 is driven to slide inward outside the limit plate 6, so that the clamping plate 9 clamps the workpiece to be processed.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
