Description

Technical Field

[0001] The present invention relates to the technical field of fastener cutting, and specifically to an automatic cutting device for fastener processing. Background Art

[0002] Fasteners are commonly used connecting components in mechanical engineering for fixing two or more components together. They usually have standard shapes and sizes to meet various application requirements. However, with the development of engineering technology, the requirements for the shape, size, and function of fasteners are getting higher and higher, and various special-shaped fasteners have emerged to meet the needs in specific applications. These special-shaped fasteners may have non-standard head shapes, thread designs, or overall structures. Therefore, special cutting devices are required during the processing to ensure their accuracy and performance.

[0003] In reality, when cutting fasteners, only fasteners of fixed models can be clamped and limited for cutting. However, in reality, there are various special-shaped fasteners of different shapes. The existing fastener cutting devices cannot perform more secure limited cutting on special-shaped fasteners. Therefore, the overall cutting device will reduce the processing efficiency in reality, and also reduce the quality during processing and the accuracy of cutting in reality due to human error factors, thus increasing the related production costs, affecting the overall performance and reliability of the product, resulting in a decline in customer satisfaction, and affecting the reputation and market competitiveness of the enterprise.

[0004] At the same time, when cutting fasteners of different shapes, a large amount of debris will be generated. If the debris generated during cutting is not processed in a timely manner, it will have a certain impact on the environment, and also increase the related production safety hazards. Environmental pollution and safety hazards may damage the enterprise image and hinder the sustainable development of the enterprise.

[0005] Moreover, after the overall cutting is completed, the fasteners cannot be collected and processed, which will lead to inventory chaos, making it difficult to accurately count the quantity and types of parts, affecting inventory management and production plans. Additionally, if they are not centrally collected and processed, it will also become a safety hazard, and employees are prone to tripping and causing personal injuries when walking or working.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The automatic cutting device for processing such fasteners can provide a relevant power source when limiting the fasteners through the use of a fixed plate and a cylinder. Only one set of cylinders can reduce energy consumption. Through the use of a connecting block, a connecting torsion spring, an elastic rod, a connecting frame, a connecting rotating rod, a first ratchet plate, and a proximity switch, it is possible to first perform relevant limiting abutment on regular fasteners through operation. When limiting irregular fasteners, one side of the anti-slip abutment pad can be first abutted against the fastener, and then the abutment of the other set of anti-slip abutment pads can be driven, so as to limit the irregular fasteners. Through the use of a fixed bottom plate and a T-shaped limiting groove, when the position of the connecting frame moves left and right, the stability during parallel operation can be ensured. Through the use of a proximity switch, the driving force of the cylinder can be weakened and changed, and an adaptive limiting abutment operation can be performed on fasteners of different quality models, thus solving the problem of how to perform limiting abutment on fasteners, achieving the effect of adapting to special-shaped fasteners, improving the efficiency of limiting fasteners, realizing automatic limiting abutment, avoiding human factor errors, improving the quality and accuracy during cutting, reducing relevant production costs, and improving the overall performance and reliability of the product.

[0019] 2. The automatic cutting device for processing such fasteners can slide the U-shaped support on the outer surfaces of the screw and the limiting rod through the use of a first receiving plate, a second motor, a screw, a second receiving plate, and a limiting rod, and can sweep the debris generated during cutting, and can conveniently clean and collect the debris generated during cutting. Then, through the use of a concave pushing plate, when the position of the screw slides on the outer surfaces of the limiting rod and the screw, the synchronous sliding of the concave pushing plate can be driven, and the position of the concave pushing plate can slide on the outer surface of the rectangular plate, so as to clean the debris falling on the upper surface of the rectangular plate during cutting. Through the use of a debris collection box and a pulling frame, the cleaned debris can be collected and processed. Pulling the pulling frame can make the debris leave the inside of the cutting table for centralized processing, thus solving the problem of how to clean the debris generated during cutting, achieving the effect of conveniently cleaning the cutting debris of fasteners, being able to clean the debris in time, avoiding affecting the environment, and reducing relevant safety hazards, and improving the sustainable development of the enterprise in reality.

[0020] 3. The automatic cutting device for processing such fasteners can, by using the second electric rotating shaft and the rotating plate, make the cut fasteners fall on the upper surface of the rotating plate. Then, under the power action of the second electric rotating shaft, it drives the cut fasteners to fall. Through the setting and use of the cutting collection box, the chute, and the electric slide rail, the fasteners collected inside can leave the inside of the cutting table under the power action of the electric slide rail, so as to centrally process the cut fasteners. By using the buffer baffle, it can buffer the falling of the cut fasteners to avoid damage to the fasteners, improve the quality after cutting, and thus solve the problem of how to collect the fasteners after cutting, achieving the effect of collection during cutting and collection, avoiding inventory chaos. The staff can accurately count the quantity and types of parts, avoid chaotic placement, and avoid tripping people, which can improve safety in reality. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-4, an automatic cutting device for fastener processing, including a cutting table 1. On both sides of the upper surface of the cutting table 1, there are provided limit abutting parts 35. The limit abutting part 35 includes a fixing plate 7, a cylinder 8, a fixing frame 9, a fixing U-shaped frame 10, a sliding bearing block 11, a rectangular block 12, a first electric rotating shaft 13, a steering block 14, an anti-slip abutting pad 15, a connecting block 16, a connecting torsion spring 17, a fixing bottom plate 18, a connecting frame 39, a connecting rotating rod 40 and a first ratchet plate 41. The bottom of the fixing plate 7 is fixedly connected to the upper surface of the cutting table 1. The right side of the cylinder 8 is fixedly connected to the left side of the fixing plate 7. The left side of the fixing frame 9 is fixedly connected to the right side of the fixing plate 7. The back of the fixing U-shaped frame 10 is fixedly connected to the front of the fixing frame 9. The outer surface of the sliding bearing block 11 is slidably connected to the inner wall of the fixing U-shaped frame 10. The left side of the rectangular block 12 is fixedly connected to the right side of the sliding bearing block 11. The outer surface of the first electric rotating shaft 13 is rotatably connected to the inside of the rectangular block 12. The inside of the steering block 14 is fixedly connected to the outer surface of the first electric rotating shaft 13. The left side of the anti-slip abutting pad 15 is fixedly connected to the right side of the steering block 14. The left side of the connecting block 16 is fixedly connected to one end of the output shaft of the cylinder 8. One end of the connecting torsion spring 17 is clamped inside the right side of the connecting block 16. The upper surface of the fixing bottom plate 18 is fixedly connected to the bottom of the fixing frame 9. A T-shaped limit groove 19 is opened inside the fixing bottom plate 18. The bottom of the connecting frame 39 is slidably connected to the inner wall of the T-shaped limit groove 19. The outer surface of the connecting rotating rod 40 is slidably connected to the inside of the connecting frame 39. The inside of the first ratchet plate 41 is fixedly connected to the outer surface of the connecting rotating rod 40, and the inside of the left side of the first ratchet plate 41 is clamped to the other end of the connecting torsion spring 17. A second ratchet plate 42 is fixedly installed on the back of the sliding bearing block 11. The back of the second ratchet plate 42 meshes with the front of the first ratchet plate 41. The right side of the connecting block 16 is clamped to one end of an elastic rod 44, and the other end of the elastic rod 44 is clamped to the left side of the first ratchet plate 41. The upper and lower surfaces of the first ratchet plate 41 are both in contact with the inside of the connecting frame 39. A proximity switch 43 is arranged inside the fixing bottom plate 18. The outer surface of the steering block 14 is in contact with the inside of the rectangular block 12. Anti-slip grooves are evenly arranged on the right side of the anti-slip abutting pad 15.

[0031] Specifically, through the drive of the cylinder 8, the connecting block 16 drives the connecting torsion spring 17 and the first gear plate 41 to move, and then engages with the second gear plate 42 for transmission, thereby realizing the smooth sliding and precise positioning of the sliding receiving block 11 and the steering block 14 on the fixed U-shaped frame 10. This design not only improves the adjustment efficiency of the limiting abutment part 35, but also ensures its flexibility and accuracy under different working requirements. The anti-slip abutment pad 15 design on the steering block 14, especially the anti-slip grooves evenly arranged on its right side, effectively increases the friction between the material being processed and prevents the material from sliding or displacing during the cutting process. Moreover, through the detachable use of the connecting torsion spring 17, it can be adapted to the use in different occasions in practice according to the weight and size of the actual limited abutment fastener.

[0032] See also Figure 5 , debris cleaning parts 36 are provided on both sides of the upper surface of the cutting table 1, and the debris cleaning parts 36 include a first receiving plate 20, a second motor 21, a screw 22, a concave pushing plate 23, a U-shaped receiving frame 38, a second receiving plate 24 and a limiting rod 25, the outer surface of the first receiving plate 20 is fixedly connected to the inside of the cutting table 1, the right side of the second motor 21 is fixedly connected to the left side of the first receiving plate 20, one end of the screw 22 is fixedly connected to the output shaft of the second motor 21, and the inside of the U-shaped receiving frame 38 is fixedly connected to the outer surface of the screw 22 Rotating connection, the upper surface of the concave pushing plate 23 is fixedly connected to the bottom of the U-shaped receiving frame 38, the outer surface of the second receiving plate 24 is fixedly connected to the inside of the cutting table 1, one end of the limiting rod 25 is fixedly connected to the right side of the second receiving plate 24, the outer surface of the limiting rod 25 is slidably connected to the inside of the U-shaped receiving frame 38, the inside of the cutting table 1 is slidably connected with a debris collection box 26, two sets of pulling frames 27 are installed on the left side of the debris collection box 26, and the right sides of the two sets of pulling frames 27 are fixedly connected to the left side of the debris collection box 26.

[0033] Specifically, the second motor 21 drives the screw 22 to rotate, thereby driving the concave pushing plate 23 to slide along the surface of the cutting table 1 under the guidance of the U-shaped receiving frame 38 and the limiting rod 25, effectively pushing the debris and waste generated during the cutting process into the debris collection box 26. This process realizes the automatic collection and cleaning of debris, greatly reducing the burden of manual cleaning. The rotational connection between the U-shaped receiving frame 38 and the screw 22 and the sliding connection between the limiting rod 25 together constitute a stable pushing mechanism, which ensures the stability and accuracy of the concave pushing plate 23 during the pushing process and avoids the omission of debris caused by shaking or deviation. The setting of the pulling frame 27 makes it more convenient to extract and replace the debris collection box 26. The operator only needs to pull it lightly to complete it, thereby improving work efficiency and convenience of operation.

[0034] See also Figure 6 and Figure 7, a centralized collection part 37 is arranged inside the cutting table 1. The centralized collection part 37 includes a rectangular plate 28, a second electric rotating shaft 29, a rotating plate 30, a cutting collection box 31, an electric slide rail 33 and a buffer baffle 34. The outer surface of the rectangular plate 28 is fixedly connected to the inside of the cutting table 1. The outer surface of the second electric rotating shaft 29 is rotatably connected to the inside of the rectangular plate 28. The inside of the rotating plate 30 is fixedly connected to the outer surface of the second electric rotating shaft 29. The bottom of the cutting collection box 31 fits against the bottom end inside the cutting table 1. A chute 32 is opened at the bottom of the cutting collection box 31. The bottom of the electric slide rail 33 is fixedly connected to the bottom end inside the cutting table 1. The left side of the buffer baffle 34 is fixedly installed inside the left side of the cutting collection box 31. The upper surface of the rectangular plate 28 fits against the bottom of the concave pushing plate 23. The four sides of the rotating plate 30 fit against the inside of the rectangular plate 28.

[0035] Specifically, the combination of the second electric rotating shaft 29 and the rotating plate 30 enables the cut fasteners to be effectively guided into the cutting collection box 31. Through the rotation of the rotating plate 30, the collection direction of the cut fasteners can be flexibly adjusted according to the specific position of the cutting operation, improving the collection efficiency and accuracy of the cut fasteners. The combined use of the cutting collection box 31 and the electric slide rail 33 enables the cutting collection box 31 to slide easily inside the cutting table 1, facilitating the operator to quickly take out the cutting collection box 31 filled with cut fasteners and replace it with a new empty box, reducing the time for collecting the cut fasteners and improving the work efficiency. The setting of the buffer baffle 34 effectively prevents the cut fasteners from splashing and scattering when falling, keeping the working environment clean. At the same time, it also reduces the impact of the cut fasteners on the equipment and extends the service life of the equipment.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3 , a connecting frame 2 is fixedly installed on the upper surface of the cutting table 1. A hydraulic cylinder 3 is fixedly installed on the upper surface of the connecting frame 2. The output shaft of the hydraulic cylinder 3 is fixedly connected to an L-shaped frame 4. A first motor 5 is fixedly installed on the right side of the L-shaped frame 4. The output shaft of the first motor 5 is fixedly connected to a grinding wheel cutter 6. Two groups of third bearing plates 45 are fixedly installed on the outer wall of the cutting table 1. A group of first placing plates 46 are fixedly connected to the closer side of the two groups of third bearing plates 45. A group of electric push rods 47 are fixedly installed inside the two groups of third bearing plates 45. One end of each of the two groups of electric push rods 47 is fixedly installed with a group of second placing plates 48, and the two groups of second placing plates 48 are both slidably connected to the inner walls of the third bearing plates 45.

[0037] Specifically, by using the hydraulic cylinder 3, the effect of precisely adjusting the heights of the L-shaped frame 4 and the grinding wheel cutter 6 is achieved, so as to adapt to the cutting requirements of materials with different thicknesses, improving the flexibility and applicability of the cutting operation. At the same time, by driving the grinding wheel cutter 6 to rotate through the first motor 5, an efficient and stable cutting process is realized, not only improving the cutting efficiency, but also ensuring the flatness and quality of the cutting surface. In addition, the fixed installation of the connecting frame 2 ensures the stability of the structure of the entire cutting device, providing a solid foundation for precise cutting. Through the settings and use of the receiving plate 45, the first placing plate 46, the second placing plate 48 and the electric push rod 47, the clamping operation of the fasteners can be carried out.

[0038] Working principle: When performing limit cutting on fasteners, the fasteners can be first clamped between the first placement plate 46 and the second placement plate 48 through the action of the bearing plate 45, the first placement plate 46, the second placement plate 48, and the electric push rod 47, so that both sides of the fasteners can be clamped, and then the position of the fasteners can be placed. After that, through the power action of the cylinder 8 fixedly installed on the left side of the fixed plate 7, when limiting the regular fasteners, the whole can be driven to move synchronously. The right side of the anti-slip abutting pad 15 is abutted against one side of the fastener to ensure the position of the fastener. When limiting the irregular fasteners, the right side of a group of anti-slip abutting pads 15 can be first abutted against one side of the fastener, and then the cylinder 8 can be started again to drive the whole to move to the right. The bottom of the synchronous T-shaped limit groove 19 slides synchronously on the inner wall of the T-shaped limit groove 19 opened in the fixed bottom plate 18, so as to avoid the change of the direction of the first ratchet plate 41 driven by the driving force. When the position of the connecting block 16 moves above the proximity switch 43, the force of the cylinder 8 can be changed to avoid damage to the fastener caused by excessive force. And then, through the action of the connecting frame 39, the connecting rotating rod 40, and the connecting torsion spring 17, the front surface of the first ratchet plate 41 meshes with the back surface of the second ratchet plate 42 and moves backward, and synchronously, the right side of another group of anti-slip abutting pads 15 can be abutted against one side of the fastener to ensure the stability of the fastener. Through the power action of the hydraulic cylinder 3 installed on the upper surface of the connecting frame 2, the position of the L-shaped frame 4 can be driven to descend. After descending to the relevant position, the first motor 5 can be started to drive the rotation of the grinding wheel cutter 6, and then the limited fasteners can be cut. During cutting, a lot of debris will be generated, and the debris will fall on the upper surfaces of the rectangular plate 28 and the rotating plate 30. When cleaning and collecting the debris, through the power action of the second motor 21 fixedly installed on the left side of the first bearing plate 20, the rotation of the screw rod 22 fixedly connected to the output shaft of the second motor 21 can be driven. Thus, the position of the rectangular plate 28 can slide on the outer surfaces of the screw rod 22 and the limit rod 25 under the limiting action of the limit rod 25. When sliding at the position of the U-shaped bearing frame 38, the synchronous movement of the concave pushing plate 23 fixedly installed at the bottom of the U-shaped bearing frame 38 can be driven. Then, the concave pushing plate 23 can move on the upper surfaces of the rectangular plate 28 and the rotating plate 30 to push the debris generated during cutting, and the debris can be pushed into the debris collection box 26. After the debris in the debris collection box 26 accumulates to a certain extent, the pulling frame 27 can be pulled to move the position of the debris collection box 26 out of the cutting table 1 to process the accumulated debris. After cleaning the debris, the cut fasteners can be collected. First, the debris on the upper surface of the rotating plate 30 can be cleaned, and then the cut fasteners can be loosened, so that the fasteners can fall on the upper surface of the rotating plate 30. Then, through the power action of the second electric rotating shaft 29 rotating inside the rectangular plate 28, the rotation of the rotating plate 30 can be driven.The fasteners that fall on the upper surface of the rotating plate 30 can fall into the inside of the cutting and collecting box 31. After falling into the inside of the cutting and collecting box 31, the buffer baffle 34 fixedly installed inside the cutting and collecting box 31 can buffer the fasteners that fall into the inside of the cutting and collecting box 31 to avoid damage to the fasteners. After the fasteners are collected, the power of the electric slide rail 33 fixedly installed at the bottom inside the cutting table 1 can make the chute 32 opened at the bottom of the cutting and collecting box 31 slide on the outer surface of the electric slide rail 33, so that the cutting and collecting box 31 can leave the inside of the cutting table 1 and perform the operation of collecting the cut fasteners.
