Description

Technical Field

[0001] This utility model relates to the field of production and processing technology, specifically to a cutting device for screw processing. Background Technology

[0002] As a basic component in industrial production, screws are widely used in automobile manufacturing, aerospace, electronic equipment and other fields. With the development of the manufacturing industry, the requirements for product performance and quality are constantly improving, and the requirements for screw quality and processing precision are becoming more and more stringent.

[0003] However, traditional screw cutting devices currently have significant shortcomings in the processing stage. These devices can only cut threads on the screw shank and part of its surface, making it difficult to process multiple surfaces of the screw head simultaneously. This results in poor fit between the screw and the connected parts, reducing the stability and reliability of the connection. In scenarios with extremely high safety requirements, such as bridges and nuclear power equipment, this can also pose serious safety hazards. In addition, traditional equipment has poor adaptability to screws of different specifications. When changing processed products, it is necessary to frequently change tools and adjust the equipment manually, which not only results in low production efficiency but also significantly increases production costs.

[0004] Against this backdrop, the development of a cutting device that can cut threads on all surfaces of the screw head and has high versatility and high production efficiency can not only meet the stringent quality requirements of high-end manufacturing industries and reduce equipment investment and labor costs, but also inject new vitality into the technological innovation of the screw processing industry.

[0005] A search revealed prior art publication number CN112276238A, which discloses a cutting device for machining, particularly a cutting device for screw machining. This invention provides a screw machining cutting device capable of uniform cutting and reducing errors. The device includes: a main base plate with an extended base plate connected to one side; a mounting plate with a mounting plate connected to the end of the main base plate; a chip hopper connected to the side of the main base plate near the mounting plate; a support rod connected to the extended base plate; a storage plate connected to the support rod; and a cutting mechanism installed between the storage plate and the mounting plate. The invention's clamping device secures the screw within the cutting mechanism, and a limiting mechanism assists the cutting mechanism in its operation. The cutting mechanism and the rotating mechanism work together to uniformly cut the screw's edges, eliminating the need for manual hand-held cutting and thus reducing errors.

[0006] Therefore, based on the above search and combined with the existing methods, the above solutions can only cut and grind the outer wall of the screw, and cannot cut the screw head from all directions, which has limitations. In order to solve the problem of not being able to cut the screw head from all directions, we propose a screw cutting device. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a cutting device for screw processing, which solves the problems mentioned below.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

A rotating wheel is fixedly connected to the output end of the drive motor, and a mating rod is fixedly connected to the end of the rotating wheel away from the drive motor. Moving blocks are slidably connected to the outer walls of the two connecting rods, and a rectangular opening is provided inside the moving block. The outer wall of the mating rod abuts against the inner wall of the rectangular opening.

[0011] As a further aspect of this solution, the edge-cutting mechanism includes a third connecting plate, which is fixedly connected to the outer wall of the moving block. The upper and lower ends of the third connecting plate are respectively fixedly connected to a second rubber sleeve and a first rubber sleeve. The end of the moving block near the third connecting plate is also fixedly connected to a connecting arm, and the end of the connecting arm away from the third connecting plate is fixedly connected to a first connecting plate and a second connecting plate.

[0012] As a further aspect of this solution, a first elastic telescopic rod is fixedly connected to the bottom of the first connecting plate. The first elastic telescopic rod and the second rubber sleeve are fixedly connected through a pipe. A second elastic telescopic rod is fixedly connected to both the left and right ends of the second connecting plate. A cutting blade is fixedly connected to the output ends of both the second elastic telescopic rod and the first elastic telescopic rod. The second elastic telescopic rod and the first rubber sleeve are fixedly connected through a pipe.

[0013] As a further aspect of this solution, the limiting mechanism includes a gear, which is rotatably connected to the outer wall of the third connecting plate. A rack is fixedly connected between the mounting base and the abutment plate, and the rack meshes with the gear.

An abutting strip is fixedly connected between every four parallel second connecting plates, and the abutting strip is located inside the abutting pipe.

[0015] This utility model provides a cutting device for screw processing. Compared with the prior art, it has the following advantages:

[0016] Beneficial effects:

[0017] As the screw rotates, the outer wall of the cutting blade at the output end of the first elastic telescopic rod abuts against the upper end of the screw head. At this time, the screw is still rotating, and the cutting blade will cut off the residual material and threads at the upper end of the screw head. The extension of the second elastic telescopic rod will drive the corresponding second elastic telescopic rod to abut against the left and right ends of the screw head. When the screw rotates, the residual material and threads on the left and right sides will be cut off. In this way, the residual material and threads on the screw head can be cut off more cleanly.

[0024] 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.

[0025] Example 1: Please refer to Figure 1 This utility model provides a technical solution: a screw cutting device, including a mounting base 3, two connecting rods 8 fixedly connected to the upper end of the mounting base 3, the two connecting rods 8 being symmetrically distributed front and back at the upper end of the mounting base 3, an abutment plate 1 fixedly connected between the two connecting rods 8, a power mechanism 101 fixedly installed between the two connecting rods 8 and the mounting base 3, a limiting mechanism 201 for fixing screws fixedly installed between the two connecting rods 8, a cutting mechanism 301 for cutting the large head of screws is also provided above the mounting base 3, and a magnetic block 2 is fixedly connected to the upper end of the mounting base 3.

[0026] Example 2: Please refer to Figure 2 , Figure 3 The power mechanism 101 includes a drive motor 6, which is fixedly mounted on the upper end of the mounting base 3. The output end of the drive motor 6 is bolted to a rotating wheel 4. Multiple weight-reducing openings are provided on the outer wall of the rotating wheel 4, arranged circumferentially. A mating rod 7 is fixedly connected to the end of the rotating wheel 4 furthest from the drive motor 6. Moving blocks 5 are slidably connected to the outer walls of two connecting rods 8. Specifically, two sliding openings are provided inside the moving block 5, symmetrically distributed front and back on the outer wall of the moving block 5. Each sliding opening... The inner walls are all slidably connected to the outer walls of the corresponding connecting rods 8. When the moving block 5 slides on the outer wall of the connecting rod 8 through the sliding port, the connecting rod 8 can limit the moving block 5 through the sliding port and also has a guiding function, improving the stability of the moving block 5 when it moves. The inner wall of the sliding port and the outer wall of the connecting rod 8 are both coated with lubricating oil. The lubricating oil can greatly reduce the friction between the inner wall of the sliding port and the connecting rod 8, and extend the service life of the sliding port and the connecting rod 8. The moving block 5 has a rectangular opening 9 inside, and the outer wall of the mating rod 7 and the inner wall of the rectangular opening 9 abut against each other.

[0027] Please see Figure 3 - Figure 4The trimming mechanism 301 includes a third connecting plate 10, which is bolted to the outer wall of the movable block 5. A second rubber sleeve 16 and a first rubber sleeve 11 are fixedly connected to the upper and lower ends of the third connecting plate 10, respectively. Both the second rubber sleeve 16 and the first rubber sleeve 11 are made of rubber, which has good elasticity, corrosion resistance, and high-temperature resistance, making it durable. A connecting arm 13 is also fixedly connected to the end of the movable block 5 closest to the third connecting plate 10. A first connecting plate 14 and a second connecting plate 22 are fixedly connected to the end of the connecting arm 13 furthest from the third connecting plate 10. The first connecting plate 14 and the second connecting plate 22 are symmetrically distributed vertically on the outer wall of the connecting arm 13. The bottom of the first connecting plate 14 is fixedly connected to the first elastic telescopic rod 18. The first elastic telescopic rod 18 and the second rubber sleeve 16 are fixedly connected through a pipe. The left and right ends of the second connecting plate 22 are fixedly connected to the second elastic telescopic rod 21. The output ends of the second elastic telescopic rod 21 and the first elastic telescopic rod 18 are fixedly connected to the cutting blades 20. The cutting blades 20 at the output ends of the first elastic telescopic rod 18 and the second elastic telescopic rod 21 are arranged horizontally and vertically. The second elastic telescopic rod 21 and the first rubber sleeve 11 are fixedly connected through a pipe.

[0028] The limiting mechanism 201 includes a gear 15, which is rotatably connected to the outer wall of the third connecting plate 10 via a rotating shaft. A rack 12 is fixedly connected between the mounting base 3 and the abutment plate 1, and the rack 12 meshes with the gear 15. An abutment tube 19 is fixedly connected to the end of the gear 15 away from the third connecting plate 10. An abutment barrel 17 with a reset function is slidably connected to the outer wall of the abutment tube 19. The abutment barrel 17 and the abutment tube 19 are fixedly connected by a second spring 26. The second spring 26 can drive the abutment barrel 17 to reset quickly. An abutment sleeve 24 is fixedly connected to the left end of the abutment barrel 17. Multiple second connecting plates 22 with reset functions are slidably connected to the outer wall of the abutment tube 19. Each second connecting plate 22 is fixedly connected to the abutment tube 19 by a first spring 23. An abutment strip 25 is fixedly connected between every four parallel second connecting plates 22. The abutment strip 25 is located inside the abutment tube 19.

[0029] Working principle: In use, simply pull the abutment barrel 17. When the inner wall of the abutment barrel 17 disengages from the outer wall of all the second connecting plates 22, the first spring 23 will drive the second connecting plates 22 and the abutment strip 25 to reset. At this time, insert the tail of the screw into the inside of the abutment tube 19, and the large end of the screw abuts against the outer wall of the abutment tube 19. Then release the pull on the abutment barrel 17, and the second spring 26 will drive the abutment barrel 17 and the abutment sleeve 24 to reset. The abutment sleeve 24 first abuts against the outer wall of the second connecting plate 22, and the outer wall of the second connecting plate 22 will abut against the inner wall of the abutment sleeve 24. When the abutment sleeve 24 and the abutment barrel 17 continue to move, the outer wall of the second connecting plate 22 will abut against the inner wall of the abutment barrel 17, and the second connecting plate 22 will drive the abutment strip 25 to abut against the outer wall of the screw tail, thus fixing the screw.

[0030] At this time, the drive motor 6 is started. The drive motor 6 will drive the rotating wheel 4 to rotate. The rotating wheel 4 will drive the mating rod 7 to move inside the rectangular opening 9. The mating rod 7 will move along the inner wall of the rectangular opening 9. The moving block 5 will move back and forth on the outer wall of the connecting rod 8. The moving block 5 will drive the connecting arm 13 and the third connecting plate 10 to move up and down. When the third connecting plate 10 moves up and down back and forth, the gear 15 will move along the outer wall of the rack 12. The gear 15 will rotate. The gear 15 will drive the abutment tube 19 and the fixed screw to rotate.

[0031] When the third connecting plate 10 moves upward, the upper end of the second rubber sleeve 16 abuts against the bottom of the abutment plate 1, and the gas inside the second rubber sleeve 16 enters the first elastic telescopic rod 18. The outer wall of the cutting blade 20 at the output end of the first elastic telescopic rod 18 abuts against the upper end of the screw head. It is worth noting that since the first rubber sleeve 11 and the second rubber sleeve 16 are made of rubber, when the third connecting plate 10 presses the second rubber sleeve 16 and the first rubber sleeve 11 from above and below, the second rubber sleeve 16 and the first rubber sleeve 11 can expand. When the first elastic telescopic rod 18 outputs... When the outer wall of the cutting blade 20 at the end abuts against the upper end of the screw head, the screw is still rotating. The cutting blade 20 will cut off the residual material and wire at the upper end of the screw head. When the third connecting plate 10 descends, the first rubber sleeve 11 is squeezed. The gas inside the first rubber sleeve 11 will enter the two second elastic telescopic rods 21. The extension of the second elastic telescopic rods 21 will drive the corresponding second elastic telescopic rods 21 to abut against the left and right ends of the screw head. When the screw rotates, the residual material and wire on the left and right sides will be cut off. The falling debris will be attracted and collected by the magnetic block 2.

[0032] After the trimming is completed, the mating rod 7 is aligned with the center of the rotating wheel 4. At this point, the abutment barrel 17 is pulled. According to the working principle described above, when all the abutment bars 25 disengage from the outer wall of the screw, the screw can be removed.
