DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a three-station eccentric wheel pressing device, including a workbench 1, a hydraulic rod 2 is fixedly connected inside the workbench 1, a fixed block 3 is fixedly connected to the output end of the hydraulic rod 2, a rotating block 4 is rotatably connected inside the fixed block 3, a fixed shaft 5 is fixedly connected inside the rotating block 4, a sliding block 6 is rotatably connected to the outer wall of the fixed shaft 5, a clamping block 8 is fixedly connected to one side of the outer wall of the sliding block 6, a slide groove 9 is opened inside the workbench 1, the outer wall of the clamping block 8 is slidably connected to the inner wall of the slide groove 9, a limiting groove 7 is opened inside the workbench 1, one side of the outer wall of the clamping block 8 is slidably connected to the inner wall of the limiting groove 7, a connecting plate 10 is fixedly connected to the outer wall of the workbench 1, a limiting ring 11 is fixedly connected to one side of the outer wall of the connecting plate 10, and a fixing component is arranged inside the limiting ring 11.

[0023] Specifically, a hydraulic rod 2 is provided inside the workbench 1, and the hydraulic rod 2 drives the fixed block 3 to move, so that the rotating block 4 can smoothly drive the sliding block 6 to slide inside the slide groove 9. A protrusion is provided on one side of the outer wall of the sliding block 6, which can be engaged with the inside of the limiting groove 7, so as to limit the movement of the clamping block 8 and improve the stability of the device. The inner wall of the connecting plate 2 16 is provided with a pressing block 18 and a pressing block 2 19. These two pressing blocks can fix a part of the tire, so that the extrusion block 20 and the roller 21 can smoothly press the tire, which not only improves the work efficiency, but also avoids the problem of inaccurate pressing caused by tire displacement.

[0024] Reference Figure 1 and Figure 2The fixed component includes a rotating block 12, the outer wall of the rotating block 12 is rotatably connected to the inner wall of the limiting ring 11, a cam 13 is arranged on the upper surface of the rotating block 12, a motor 14 is arranged just above the limiting ring 11, and the output end of the motor 14 is fixedly connected to the inside of the cam 13, the upper surface of the rotating block 12 is fixedly connected to a fixed block 15, one side of the outer wall of the cam 13 is slidably connected to the outer wall of the fixed block 15, an extrusion block 20 is arranged on the lower surface of the rotating block 12, a roller 21 is arranged on the lower surface of the rotating block 12, a connecting plate 16 is fixedly connected to the outer wall of the connecting plate 16, a hydraulic rod 17 is fixedly connected to the inner wall of the connecting plate 16, a pressure block 18 is fixedly connected to the output end of the hydraulic rod 17, and a pressure block 19 is arranged on the inner wall of the connecting plate 16.

[0025] Specifically, the motor 14 transmits power to the cam 13 by driving the cam 13 to rotate. The outer wall of the cam 13 fits tightly with the outer side of the fixed block 15, thereby realizing the motion control of the rotating block 12. Driven by the cam 13, the rotating block 12 presents regular motion pauses, which helps to improve the accuracy and stability of tire pressing. The outer wall of the rotating block 12 is constrained by the inner wall of the limit ring 11, and the rotation range is effectively limited. The limit ring 11 makes the movement of the rotating block 12 more stable, which helps to reduce equipment wear and extend the service life.

[0026] Working principle: when the three-station eccentric wheel pressing device is needed, first, the rotating block 4 rotating inside the fixed block 3 is driven to move by the hydraulic rod 2, so that the sliding block 6 connected to the rotating block 4 can slide inside the limit groove 7, and then the clamping block 8 can fix the workpiece to prevent the workpiece from being displaced during pressing and causing the pressing efficiency to decrease. Then, the cam 13 is driven to rotate by the motor 14, so that the cam 13 can rotate on the outer wall of the rotating block 2 12, and the extrusion block 20 and the roller 21 can follow the fixed block 2 15 and be driven to rotate by the cam 13. The cam 13 can move the fixed block 2 15 to rotate one circle, and after one circle of rotation, it drives the extrusion block 20 and the roller 21 to rotate again, and regularly presses and improves the practicality of the device. When the rotating block 2 12 rotates, it drives the extrusion block 20 to press the tire to the outside of the workpiece, so as to improve the pressing quality. The hydraulic rod 2 17 connected to the connecting plate 2 16 can drive the pressing block 1 18 to cooperate with the pressing block 2 19 to fix the position of the tire, which is convenient for the machine to perform pressing work and improve the work efficiency.

[0027] 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 substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
