[0026] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0027] Example 1

[0028] See also Figures 1 to 3 As shown, this embodiment provides a large-load lifting and positioning device, which includes a base plate 1, a cylinder 2, a lifting shaft 3, a support shaft 4, a roller bearing follower 5, and a roller 6; wherein the cylinder 2 is connected to the support shaft 4; the lifting shaft 3 is vertically installed on the base plate 1; the support shaft 4 passes through the lifting shaft 3 in a horizontal state; the roller bearing follower 5 is arranged at the upper end of the lifting shaft 3, and the roller 6 is arranged at the lower end of the lifting shaft 3.

[0029] In this embodiment, the upper surface of the support shaft 4 is provided with an upper inclined groove 7, and the lower surface is provided with a lower inclined groove 8. Figure 4 and 5 As shown, the upper inclined groove 7 contacts the roller bearing follower 5, and the lower inclined groove 8 contacts the roller 6. Specifically, the upper surface of the support shaft 4 is provided with an upper inclined groove 7, as shown in FIG. Figure 4 and 5 As shown, the inclined groove 7 opens upward, and the inclined surface is inclined to the upper left; the roller bearing follower 5 is installed at the upper end of the lifting shaft 3 and contacts the upper surface groove 7 of the support shaft 4. When the cylinder 2 moves with the support shaft 4, the roller bearing follower 5 will be carried by the support shaft 4 to roll on the inclined surface of the upper surface groove 7, thereby driving the lifting shaft 3 to move upward. The lower surface of the support shaft 4 is provided with a lower inclined groove 8, which opens downward and the inclined surface is inclined to the lower right; the roller 6 is installed at the lower end of the lifting shaft 3 and contacts the lower surface groove 8 of the support shaft 4. When the cylinder 2 moves with the support shaft 4, the roller 6 will be carried by the support shaft 4 to roll on the inclined surface of the lower surface groove 8, thereby driving the lifting shaft 3 to move downward.

[0030] In this embodiment, guide sleeves 9 are installed at both ends of the support shaft 4. Specifically, guide sleeves 9 are installed at both ends of the support shaft 4, and the guide sleeves 9 are used to limit the movement of the support shaft 4 in the axial direction. The support shaft 4 is connected to the cylinder 2. When the cylinder 2 moves, it will drive the movement of the support shaft 4. The guide sleeves 9 play a guiding role at this time. When the support shaft 4 moves forward and hits the guide sleeves 9, it means that the cylinder 2 has completed an extension action.

[0031] In this embodiment, the roller bearing follower 5 is installed on the upper end of the lifting shaft 3 through the first shaft pin 14, and the roller 6 is installed on the lower end of the lifting shaft 3 through the second shaft pin 15. In addition, a round pin 13 is provided at the top of the lifting shaft 3 for fixing the lifting tray. Specifically, the roller bearing follower 5 is installed on the upper end of the lifting shaft 3 through the first shaft pin 14 and contacts the upper surface groove 7 of the support shaft 4. When the cylinder 2 extends forward and moves forward with the support shaft 4, the roller bearing follower 5 rolls counterclockwise on the inclined surface of the upper surface groove 7 along with the first shaft pin 14, and the lifting shaft 3 moves upward along the rotation direction of the first shaft pin 14. The roller 6 is installed at the lower end of the lifting shaft 3 through the second shaft pin 15 and contacts the lower surface groove 8 of the support shaft 4. When the cylinder 2 retracts and takes the support shaft 4 backward, the roller bearing follower 5 rolls clockwise on the inclined surface of the upper surface groove 7 along with the first shaft pin 14. At the same time, the backward movement of the support shaft 4 causes the lower surface groove 8 to roll clockwise on the inclined surface of the lower surface groove 8 with the roller 6 along with the second shaft pin 15, and the lifting shaft 3 moves downward along the rotation direction of the first shaft pin 14 and the second shaft pin 15. A round pin 13 is also provided at the top of the lifting shaft 3, and the round pin 13 is used to fix the tray that holds the objects to be lifted.

[0032] In this embodiment, the lifting and positioning device includes a mounting seat 10, which is fixed to the bottom plate 1 through a pad 11; the lifting shaft 3 is vertically mounted on the mounting seat 10, and the upper and lower ends are clamped by a clamping sleeve 12. Specifically, the mounting seat 10 is vertically mounted on the bottom plate 1. In order to make the mounting seat 3 stable, the device inserts a pad 11 between the mounting seat 10 and the bottom plate 1; the lifting shaft 3 passes through the mounting seat 10 in a vertical state, and the upper and lower ends of the lifting shaft 3 are clamped by clamping sleeves to ensure the stability of the lifting shaft and the safety of the lifting process.

[0033] In this embodiment, the cylinder 2 is connected to the support shaft 4 through the cylinder joint 16, and the cylinder 2 is fixed to the bottom plate 1 through the cylinder bracket 17. Specifically, the cylinder 2 is connected to the support shaft 4 through the cylinder joint 16, and when the telescopic rod of the cylinder 2 extends forward, the support shaft 4 will also move forward together with the telescopic rod of the cylinder 2, and when the telescopic rod of the cylinder 2 retracts backward, the support shaft 4 will retract backward accordingly. The cylinder bracket 17 is fixed to the bottom plate 1 and is used to support the cylinder 2.

[0034] In this embodiment, a lifting and positioning device for a large load is provided. The lifting and positioning device drives a supporting shaft to move forward and backward through the action of a cylinder, and drives the lifting shaft to complete lifting and lowering by using the movement of a roller bearing follower and a roller on the inclined surface of the supporting shaft, thereby realizing the lifting and positioning function. The device meets the use requirements of large load lifting and positioning, and has a short cycle time, thereby reducing the working cost.

[0035] The working principle of the utility model is to control the extension and retraction movement of the cylinder 2. When the cylinder 2 extends forward, the roller bearing follower 5 rolls counterclockwise along the upper inclined groove 7 of the support shaft 4, driving the lifting shaft 3 to move upward. When the cylinder 2 is fully extended, it indicates that it has reached the positioning point, and the lifting positioning function is realized; when the cylinder 2 retracts backward, the roller bearing follower 5 rolls clockwise along the upper inclined groove 7 of the support shaft 4, and at the same time, the lower inclined groove of the support shaft 4 will drive the roller 6 at the lower end of the lifting shaft 3 to move clockwise, thereby driving the lifting shaft 3 to move downward and return to its original state. This device meets the use requirements of large load lifting and positioning, and the required cycle time is short, which reduces the working cost.

Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
