Description

Technical Field

[0001] This utility model relates to the field of blade connection technology, specifically to an axial limiting installation mechanism for a rolling blade. Background Technology

[0002] In modern industrial production, cutting rollers, as a fundamental and crucial cutting tool, have a wide range of applications, almost ubiquitous in all material processing stages. Whether cutting and shaping metal materials or processing non-metallic materials such as wood, plastics, and paper, cutting rollers play an irreplaceable role. Through their sharp cutting edges and efficient rotary motion, they enable precise and efficient cutting operations, significantly improving production quality and work efficiency. Therefore, cutting rollers have become an indispensable component of modern manufacturing.

[0003] For example, patent number CN 218570881 U discloses a weeding device, including a mounting frame. A spraying mechanism is installed at the top of the mounting frame, and multiple movable wheels are connected to the bottom of the mounting frame via a connecting frame. A lifting mechanism is also symmetrically arranged at the bottom of the mounting frame, and weeding mechanisms are connected between the symmetrically arranged lifting mechanisms. The weeding mechanism at the end of the lifting mechanism can remove weeds from the ground. At least one weeding mechanism is provided. When multiple weeding mechanisms are provided, the weeding wheels of the rear weeding mechanism can be aligned with the gaps between the weeding wheels of the front weeding mechanism, thereby improving weeding efficiency and ensuring effective removal of weeds in one go. Simultaneously, the height of the weeding mechanism can be adjusted via the telescopic rod of the lifting mechanism in conjunction with a hydraulic rod, preventing damage to the blades on the surface of the weeding wheel from collision with stones or other debris due to the wheel being too low.

[0004] For example, patent number CN 216164743 U discloses a weeding device for agricultural production, including a connecting rod. The left end of the connecting rod is connected to an upper support rod and a lower support rod arranged in a V-shape. The upper support rod is fixedly connected to a wire rope weeding mechanism, and the lower support rod is fixedly connected to a serrated blade weeding mechanism. The connecting rod is connected and fixed to a rotating shaft driven by a motor on the weeder. Depending on the amount of weeds on the land or the geological conditions, the wire rope weeding mechanism or the serrated blade weeding mechanism can be selected for weeding. For soft soil with few weeds, the wire rope weeding mechanism can be selected. For Gobi deserts, mortar-rich soils, or soft soils with many weeds, the serrated blade weeding mechanism can be selected. It has dual functions. The wire rope weeding is convenient and has a good weeding effect. The structure is simple and easy to maintain. The serrated blade head rolls by itself, and the weeds are pulled up by the roots, making weeding convenient and fast.

[0005] In the blade mounting method described in the aforementioned patent, the roller blade lacks an effective limiting structure in the axial direction. This makes the roller blade prone to axial displacement when rotating at high speed or subjected to external impact. Axial displacement not only affects the cutting accuracy of the roller blade, leading to a decrease in cutting quality, but may also cause the roller blade to collide with other components, resulting in equipment damage, increased maintenance costs, and downtime. Furthermore, it prevents flexible adjustment of the distance between the various sets of blades. Utility Model Content

This solves the problem of the aforementioned hobbing cutters lacking an effective limiting structure in the axial direction. This design flaw directly leads to frequent axial displacement of the hobbing cutter during operation, resulting in decreased cutting quality. It can also cause the hobbing cutter to collide with other components, causing equipment damage, increasing maintenance costs and downtime, and preventing flexible adjustment of the distance between different sets of cutters.

[0016] 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.

[0017] Please see Figure 1-6 This utility model provides a technical solution: an axial limiting installation mechanism for a hobbing cutter, comprising a rotating spindle 1 and a tool holder 6. Two limiting worm gears 2 are disposed inside the rotating spindle 1, and a worm gear connecting block 3 is disposed between the limiting worm gears 2. Six positioning sliders 4 are disposed on each limiting worm gear 2. The positioning sliders 4 pass through the inner wall of the rotating spindle 1 and connect to four tool holder connecting blocks 5. The tool holder connecting blocks 5 are connected to the tool holder 6. A guide shaft 8 is connected between each tool holder connecting block 5. Fixed discs 13 are disposed at both ends of the guide shaft 8 and the rotating spindle 1. A pad ring 14 is disposed on the outer side of the fixed disc 13. A fixing locking plate 15 is disposed on the pad ring 14. A pulley support shaft 17 is connected to the right side of the fixing locking plate 15, and a pulley 1 is connected to the pulley 1. 8. A support shaft 20 is connected to the left side of the fixed locking plate 15. The support shaft 20 and the pulley support shaft 17 can be connected to the required carrier. The inner side of the fixed locking plate 15 is locked to the outer end of the limiting worm gear 2. The fixed locking plate 15 and the pad ring 14 are fixed with fixing screws 16. A guide fixing plate 7 is provided in the middle of the guide shaft 8. The guide fixing plate 7 is provided with four lifting eye holes 19. The lifting eye holes 19 can be connected to lifting hooks. A guide fixing block 9 is provided between the guide fixing plate 7 and the guide shaft 8. A tool holder fixing rod 10 is provided between each group of the tool holder connecting block 5 and the tool holder 6. Tool holder rod fixing rings 11 are provided at both ends of the tool holder fixing rod 10. A fixing nut 12 is provided between the tool holder fixing rod 10 and the tool holder rod fixing ring 11 to fix its position.

[0018] During use, the limiting worm gear 2 is locked by the fixing plates 15 at both ends, preventing it from rotating within the rotating spindle 1. Due to the cooperation between the positioning slider 4 and the limiting worm gear 2, the axial movement of the positioning slider 4 is also restricted. When the rotating spindle 1 rotates, the positioning slider 4 drives the tool holder connecting block 5 and the tool holder 6 to rotate together, and the hobbing blade mounted on the tool holder 6 rotates accordingly to perform the cutting work. During this process, due to the action of the limiting worm gear 2 and the positioning slider 4, the tool holder 6 and the hobbing blade are firmly fixed in the axial direction, preventing axial displacement. To adjust the distance between the blades, the mechanism can be removed from the carrier. Use a hook to lift the entire device by hooking it into the lifting eye hole 19. Then, remove the pulley support shafts 17 and 20 at both ends. Finally, unscrew the four fixing screws 16 at both ends and remove the fixing locking plates 15 at both ends, exposing the outer end of the limiting worm gear 2. Next, use a tool to rotate the limiting worm gear 2 to remove it from the inside of the rotating spindle 1. Then, adjust the axial position of the positioning slider 4 inside the rotating spindle 1. After adjustment, reinsert the limiting worm gear 2 and re-align it with the positioning slider 4. Finally, install the fixing locking plate 15, pulley support shaft 17, and support shaft 20 in sequence, and place the device back onto the carrier. This completes the adjustment of the distance between the blades.

[0019] In summary, the axial limiting mounting mechanism of this hobbing cutter has significant advantages, effectively solving the problem of insufficient axial limiting of hobbing cutters in existing technologies. Its unique limiting worm gear and positioning slider design greatly improves the axial stability of the hobbing cutter. The arrangement of the limiting worm gear allows the positioning slider to be precisely positioned within the rotating spindle, ensuring that the tool holder connecting block and tool holder are not easily displaced axially. This guarantees stability and accuracy during cutting, prevents the reduction in cutting quality caused by axial displacement, and allows for flexible adjustment of the distance between each set of cutters.
