Detailed Implementation

[0021] Example 1

[0022] like Figures 1-4 As shown, this utility model proposes a liftable double-turn positioner, including a positioner body and an adjustment assembly. The positioner body consists of a positioner head frame 1 and a positioner tail frame 2, which are symmetrically arranged. The adjustment assembly is connected to the positioner tail frame 2 and includes a slide rail 3, a movable seat 4, a first telescopic device 5, a lifting component 6, a lifting plate 7, and a locking structure. The slide rail 3 is located below the positioner tail frame 2, and the first telescopic device 5 is connected to the slide rail 3. The first telescopic device 5 is, but is not limited to, a hydraulic cylinder. The hydraulic cylinder is connected to the external... The hydraulic equipment is connected; the telescopic end of the first telescopic device 5 is connected to the movable seat 4, the movable seat 4 is slidably connected to the slide rail 3, and the lifting member 6 and the lifting plate 7 are arranged sequentially from bottom to top on the movable seat 4. The positioner tail frame 2 is connected to the lifting plate 7, and a locking structure is provided between the lifting plate 7 and the slide rail 3 to lock their positions. The locking structure has a locked state and an unlocked state. When the adjustment component is in use, the lifting member 6 pushes the lifting plate 7 to move vertically and unlocks the locking structure. The first telescopic device 5 pushes the lifting plate 7 and the positioner tail frame 2 to move horizontally.

[0023] Example 2

[0024] like Figures 2-4 As shown, the present invention proposes a liftable double-turn positioner. Compared with Embodiment 1, this embodiment describes the detailed structure of the adjustment component.

[0025] The lifting component 6 consists of a second telescopic device 8 and a moving block 9. The second telescopic device 8 is connected to the moving base 4. The second telescopic device 8 is selected from, but is not limited to, a hydraulic cylinder. The hydraulic cylinder is connected to an external hydraulic device. The telescopic end of the second telescopic device 8 is connected to the two protrusions of the moving block 9. The moving block 9 is slidably connected to the mating groove opened on the lifting plate 7.

[0026] Both the moving block 9 and the mating groove are parallelograms in shape, and the moving block 9 moves in a wedge-shaped direction. The parallelogram shape of the moving block 9 not only enables it to push the lifting plate 7 to move vertically when the wedge block moves forward, but also enables it to restrict the displacement of the lifting plate 7 when it retracts by mating with the mating groove.

[0027] Multiple guide rods 10 are connected to the movable seat 4. One end of the guide rod 10 passes through the lifting plate 7 and is connected to the limit block 11. The guide rod 10 guides the movement of the lifting plate 7 and limits its vertical movement range through the limit block 11.

[0028] The locking structure consists of a first rack 12 and a second rack 13. The parallel first rack 12 is connected to both sides of the slide rail 3, and the parallel second rack 13 is connected to both ends of the lifting plate 7 near the slide rail 3. The first rack 12 and the second rack 13 are engaged.

[0029] Displacement sensors 14 are connected to both sides of the movable seat 4; the displacement sensors 14 can monitor the moving distance of the movable seat 4 in real time, providing data support for precise adjustment of the position of the positioner tail frame 2, and ensuring the accuracy of the adjustment.

[0030] The slide rail 3 is equipped with a reference scale; during manual or assisted adjustment, the operator can intuitively understand the moving position of the moving seat 4 through the reference scale, thereby further improving the adjustment accuracy.

[0031] Multiple parallel limit pins 15 are connected to the lifting plate 7, and the slide rail 3 is provided with a limit groove 16 that cooperates with the limit groove 16. The cooperation between the limit pins 15 and the limit groove 16 can limit the displacement and tilt of the positioner tail frame 2 when it shakes during operation, and prevent overturning.

[0032] In summary, when this utility model is used and the distance between the positioner head frame 1 and the positioner tail frame 2 needs to be adjusted, the telescopic end of the first telescopic device 5 pushes the moving seat 4 and the lifting plate 7 to move horizontally along the slide rail 3. Simultaneously, the second telescopic device 8 will start before the first telescopic device 5. The telescopic end of the second telescopic device 8 drives the moving block 9 to move horizontally. When the parallelogram-shaped moving block 9 moves, it pushes the lifting plate 7 vertically through its inclined surface, and the plane of the parallelogram-shaped moving block 9 provides stable support. The lifting plate 7 moves along... As the guide rod 10 moves, the upper limit block 11 of the guide rod 10 can also limit its range of movement. When the lifting plate 7 moves upward, the second rack 13 connected below it will move away from the first rack 12 on the slide rail 3, and the limit pin 15 will also be pulled out from the limit groove 16. After moving into place, the extension end of the second telescopic device 8 retracts, causing the moving block 9 to return to the mating groove, which plays a certain role in positioning and limiting. At the same time, the lifting plate 7 falls, causing the second rack 13 to engage with the first rack 12, and the limit pin 15 is inserted into the limit groove 16 to prevent the workpiece from vibrating and shaking when rotating, which could lead to overturning.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
