Technical Field

[0001] The present invention belongs to the technical field of cutting devices, and specifically relates to a cutting device for automobile socket production and its usage method. Background Art

[0002] Automobile sockets are commonly used tools in automobile maintenance and repair, mainly used for disassembling and assembling bolts or nuts. During the production process of automobile sockets, the use of various devices is involved. Among them, the cutting device plays a crucial role. It is the core equipment in the production process of automobile sockets, and its main function is to accurately cut raw materials into the required sizes and shapes to meet the specifications of automobile sockets;

A screw rod is jointly movably connected to both sides of the inner wall of the chute plate. A slider is slidably connected inside the chute plate. A sliding bracket is fixedly installed on one side of the slider. By driving a rotating rod to rotate inside the chute plate through a first motor, the slider is linked to slide inside the chute plate, and the slider drives the sliding bracket to adjust the cutting length and distance. The cutting blade is driven by a third electric telescopic rod to cut the sealing socket.

[0018] A method for using a cutting device for producing automotive sleeves includes the following steps:

[0019] S1: When it is necessary to cut the sleeve body, first place the sleeve body on the tops of two fixed bottom plates, and make the cutting point located below the cutting structure. Then start the motor. When the motor starts, it drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the rotation of the second gear. The rotation of the second gear drives the rotation of the first gear. The rotation of the first gear drives the rotation of the first rotating shaft. When the first rotating shaft rotates, it drives another first rotating shaft to rotate synchronously through the second pulley group. When the first rotating shaft rotates, it drives the first threaded rod to rotate through the first pulley group. The rotation of the first threaded rod drives the lifting plate to move downward. The movement of the lifting plate drives the movement of the fixed top plate, so that the fixed top plate moves to the top of the sleeve body and cooperates with the fixed bottom plate to fix it. The two fixed top plates and the fixed bottom plates are respectively located on both sides of the cutting structure to fix both sides of the cutting point of the sleeve body.

[0020] S2: Then the second rotating shaft continues to rotate to drive the third gear to rotate. The rotation of the third gear drives the rotation of the fourth rotating shaft. The rotation of the fourth rotating shaft drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the third rotating shaft. When the third rotating shaft rotates, it drives the second threaded rod to rotate through the third pulley group. When the second threaded rod rotates, it drives the moving plate to move. The movement of the moving plate drives the movement of the inner shaft, so that the inner shaft moves toward the side close to the cutting structure and is embedded inside the sleeve body.

[0021] S3: At the same time, the movement of the moving plate drives the movement of the first magnetic block. When the first magnetic block moves to one side of the second magnetic block, the two are magnetically connected, causing the first magnetic block to move a certain distance toward the side of the second magnetic block. At the same time, the movement of the first magnetic block drives the movement of the connecting plate. The movement of the connecting plate drives the movement of the connecting shaft. The movement of the connecting shaft drives the movement of the guide ring. The movement of the guide ring pushes the bump upward, so that the bump closely fits against the inner wall of the sleeve body to support it.

[0022] S4: Then the sleeve body is cut by the cutting structure.

[0023] S5: After cutting, start the motor again to reverse the second rotating shaft, so that the second gear first meshes with the third gear, driving the two inner shafts to move outward and slide out of the sleeve body. Then the second gear continues to rotate and meshes with the first gear, driving the two fixed top plates to move upward and separate from the sleeve body, and the sleeve body is taken out.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. Through the setting of the fixing components, when the sleeve body needs to be cut, first place the sleeve body on the tops of the two fixed bottom plates, and make the cutting point located below the cutting structure. Then start the motor. When the motor starts, it drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the rotation of the second gear. The rotation of the second gear drives the rotation of the first gear. The rotation of the first gear drives the rotation of the first rotating shaft. When the first rotating shaft rotates, it drives another first rotating shaft to rotate synchronously through the second pulley group transmission. When the first rotating shaft rotates, it drives the first threaded rod to rotate through the first pulley group transmission. The rotation of the first threaded rod drives the lifting plate to move downward. The movement of the lifting plate drives the movement of the fixed top plate, so that the fixed top plate moves to the top of the sleeve body and cooperates with the fixed bottom plate to fix the sleeve body. By having the two fixed top plates and the fixed bottom plates located on both sides of the cutting structure respectively, the two sides of the cutting point of the sleeve body are fixed, so as to reduce the vibration and deformation of the sleeve during the cutting process, thereby improving the cutting accuracy and cutting quality.

[0026] 2. Through the setting of the convex block to support the inner wall of the sleeve body, when the sleeve body needs to be cut, first place the sleeve body on the tops of the two fixed bottom plates, and then start the motor. When the motor starts, it drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the rotation of the third gear. The rotation of the third gear drives the rotation of the fourth rotating shaft. The rotation of the fourth rotating shaft drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the third rotating shaft. When the third rotating shaft rotates, it drives the second threaded rod to rotate through the third pulley group transmission. When the second threaded rod rotates, it drives the moving plate to move. The movement of the moving plate drives the movement of the inner shaft, so that the inner shaft moves towards the side close to the cutting structure and is embedded in the inside of the sleeve body, thereby supporting the inside of the sleeve body. This can prevent the material from collapsing or deforming due to the loss of internal support during the cutting process, especially during the processing of thin-walled sleeves. By supporting the inside of the sleeve, the stress generated during the cutting process can be effectively dispersed, reducing the deformation of the material caused by stress concentration and maintaining the original shape and dimensional accuracy of the material.

[0027] 3. In the present invention, through the arrangement of the first magnetic block and the second magnetic block, when the inner shaft is inserted into the sleeve body, the movement of the moving plate drives the movement of the first magnetic block. When the first magnetic block moves to one side of the second magnetic block, the magnetic connection between the two causes the first magnetic block to move a certain distance towards one side of the second magnetic block. At the same time, the movement of the first magnetic block drives the movement of the connecting plate, the movement of the connecting plate drives the movement of the connecting shaft, and the movement of the connecting shaft drives the movement of the guiding ring. The movement of the guiding ring pushes the convex block upwards, causing the convex block to closely fit against the inner wall of the sleeve body to support it. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 7 As shown, in an embodiment of the present invention, a cutting device for automobile sleeve production includes a workbench 1, a side plate 2 is fixedly installed on the top of the workbench 1, a cutting structure 3 is installed on the bottom of the side plate 2, and a fixing component is arranged on the top of the workbench 1;

[0038] The fixed assembly includes a fixed bottom plate 6 fixedly mounted on the top of the workbench 1, two fixed bottom plates 6 are provided, the tops of the two fixed bottom plates 6 are provided with sleeve bodies 7, the tops of the two fixed bottom plates 6 are both provided with fixed top plates 5, and the tops of the two fixed top plates 5 are both fixedly connected with lifting plates 4;

[0039] The inside of the two lifting plates 4 are meshedly connected with the first threaded rod 9, the tops of the two first threaded rods 9 are connected to the first rotating shaft 11 through the first pulley set 10, the two first rotating shafts 11 are connected through the second pulley set 12, a first gear 13 is fixedly installed on the top of one of the first rotating shafts 11, a second gear 14 is meshedly connected to one side of the first gear 13, a second rotating shaft 15 is fixedly connected inside the second gear 14, and a motor 16 is installed on the top of the second rotating shaft 15.

[0040] This device is suitable for cutting the sleeve body 7 of a shorter length, such as removing end surface defects or adjusting length tolerance, and secondary precision cutting after forging, but is not suitable for fixed-length cutting of a longer length;

[0041] A limit shaft is slidably installed inside the lifting plate 4, and the limit shaft is fixedly installed at the bottom end of the side plate 2;

[0042] When the sleeve body 7 needs to be cut, first place the sleeve body 7 on the top of the two fixed bottom plates 6, and make the cutting point below the cutting structure 3. Then start the motor 16. When the motor 16 starts, it drives the second rotating shaft 15 to rotate. The rotation of the second rotating shaft 15 drives the rotation of the second gear 14. The rotation of the second gear 14 drives the rotation of the first gear 13. The rotation of the first gear 13 drives the rotation of the first rotating shaft 11. When the first rotating shaft 11 rotates, it drives another first rotating shaft 11 to rotate synchronously through the second pulley group 12. When the first rotating shaft 11 rotates, it drives the first threaded rod 9 to rotate through the first pulley group 10. The rotation of the first threaded rod 9 drives the lifting plate 4 to move downward. The movement of the lifting plate 4 drives the movement of the fixed top plate 5, so that the fixed top plate 5 moves to the top of the sleeve body 7 to cooperate with the fixed bottom plate 6 to fix the sleeve body 7. By having the two fixed top plates 5 and the fixed bottom plates 6 located on both sides of the cutting structure 3 respectively, the two sides of the cutting point of the sleeve body 7 are fixed to reduce the vibration and deformation of the sleeve during cutting, thereby improving the cutting accuracy and cutting quality.

[0043] As Figures 1 to 3 shown, buffer pads 8 are installed on the inner walls of the fixed top plate 5 and the fixed bottom plate 6.

[0044] The buffer pads 8 absorb the vibration generated during cutting, reduce its impact on the sleeve body 7 and the cutting equipment, thereby improving the cutting stability.

[0045] As Figures 1 to 7 shown, an inner shaft 18 is arranged inside the sleeve body 7. There are two inner shafts 18 symmetrically arranged. Convex blocks 19 are evenly installed on the inner walls of the two inner shafts 18. One end of each of the two inner shafts 18 is fixedly connected to a moving plate 17. The two moving plates 17 are both slidably installed inside the workbench 1;

[0046] The inner walls of the two moving plates 17 are threadedly connected to a second threaded rod 28. The second threaded rod 28 is rotatably installed inside the workbench 1. A third pulley group 29 is installed on the outer wall of the second threaded rod 28. A third rotating shaft 30 is embedded at the top of the third pulley group 29. One end of the third rotating shaft 30 is fixedly connected to a first bevel gear 31. The top of the first bevel gear 31 is meshed with a second bevel gear 32. The top of the second bevel gear 32 is fixedly installed with a fourth rotating shaft 33. The top of the fourth rotating shaft 33 is fixedly installed with a third gear 34. The third gear 34 is arranged on one side of the second gear 14 and the two are meshed.

[0047] The convex blocks 19 are elastically arranged;

[0048] Two threads are provided on the outer wall of the second threaded rod 28, and the directions of the two threads are opposite, which is used to make the two moving plates 17 move relatively;

[0049] When the sleeve body 7 needs to be cut, first place the sleeve body 7 on the tops of the two fixed bottom plates 6, and then start the motor 16. When the motor 16 starts, it drives the second rotating shaft 15 to rotate. The rotation of the second rotating shaft 15 drives the rotation of the third gear 34. The rotation of the third gear 34 drives the rotation of the fourth rotating shaft 33. The rotation of the fourth rotating shaft 33 drives the rotation of the second bevel gear 32. The rotation of the second bevel gear 32 drives the rotation of the first bevel gear 31. The rotation of the first bevel gear 31 drives the rotation of the third rotating shaft 30. When the third rotating shaft 30 rotates, it drives the rotation of the second threaded rod 28 through the third pulley group 29. When the second threaded rod 28 rotates, it drives the moving plate 17 to move. The movement of the moving plate 17 drives the movement of the inner shaft 18, so that the inner shaft 18 moves towards the side close to the cutting structure 3 and is embedded in the interior of the sleeve body 7, thereby supporting the interior of the sleeve body 7 and preventing the material from collapsing or deforming due to the loss of internal support during the cutting process, especially during the processing of thin-walled sleeves. By supporting the inside of the sleeve, the stress generated during the cutting process can be effectively dispersed, reducing the deformation of the material caused by stress concentration and maintaining the original shape and dimensional accuracy of the material.

[0050] It should be noted that when the two inner shafts 18 are embedded in the sleeve body 7, there should be enough distance in the middle for cutting.

[0051] As Figure 5 shown, the third gear 34 and the first gear 13 are symmetrically distributed on both sides of the second gear 14.

[0052] The tooth blocks on the outer wall of the second gear 14 are fan-shaped distributed;

[0053] When cutting the sleeve body 7, the second gear 14 rotates and first meshes with the first gear 13, so that the two fixed top plates 5 first move downwards to fix the sleeve body 7, and then the second gear 14 continues to rotate and meshes with the third gear 34 to drive the two inner shafts 18 to move inwards and be embedded in the sleeve body 7 for support;

[0054] After cutting the sleeve body 7, the motor 16 is driven to reverse the second rotating shaft 15, so that the second gear 14 rotates and first meshes with the third gear 34, driving the two inner shafts 18 to move outwards and slide out of the sleeve body 7, and then the second gear 14 continues to rotate and meshes with the first gear 13 to drive the two fixed top plates 5 to move upwards and separate from the sleeve body 7.

[0055] As Figure 6 and Figure 7 shown, a connecting shaft 23 is arranged inside the inner shaft 18, and a guide ring 22 is fixedly installed on the outer wall of the connecting shaft 23, and the guide rings 22 are evenly distributed.

[0056] As Figure 6 andFigure 7 As shown, the bumps 19 are uniformly arranged in an annular array, and one end of each bump 19 is disposed on the outer wall of the guiding ring 22.

[0057] As Figure 3 and Figure 6 shown, one end of the connecting shaft 23 is fixedly connected with a connecting plate 24. A first magnetic block 26 is fixedly installed at the end of the connecting plate 24 away from the connecting shaft 23. A second magnetic block 27 is magnetically connected to one side of the first magnetic block 26, and the second magnetic block 27 is fixedly installed on the inner wall of the workbench 1.

[0058] When the inner shaft 18 is inserted into the sleeve body 7, the movement of the moving plate 17 drives the movement of the first magnetic block 26. When the first magnetic block 26 moves to one side of the second magnetic block 27, the magnetic connection between the two causes the first magnetic block 26 to move a certain distance towards one side of the second magnetic block 27. At the same time, the movement of the first magnetic block 26 drives the movement of the connecting plate 24, the movement of the connecting plate 24 drives the movement of the connecting shaft 23, and the movement of the connecting shaft 23 drives the movement of the guiding ring 22. The movement of the guiding ring 22 pushes the bumps 19 upwards, causing the bumps 19 to closely fit against the inner wall of the sleeve body 7 to support it.

[0059] As Figure 6 shown, the connecting plate 24 is slidably installed inside the moving plate 17, and a tension spring 25 is installed between the connecting plate 24 and the moving plate 17.

[0060] Both ends of the tension spring 25 are fixedly connected to the moving plate 17 and the first magnetic block 26 respectively;

[0061] When the first magnetic block 26 is adsorbed by the second magnetic block 27 and slides inside the moving plate 17, the tension spring 25 deforms to store elastic potential energy;

[0062] After cutting, when the moving plate 17 moves outwards, the first magnetic block 26 separates from the second magnetic block 27. The elastic potential energy stored in the tension spring 25 is released to move the first magnetic block 26 back to its original position. The movement of the first magnetic block 26 drives the movement of the connecting plate 24, the movement of the connecting plate 24 drives the movement of the connecting shaft 23, and the movement of the connecting shaft 23 drives the movement of the guiding ring 22, causing the guiding ring 22 to move away from the bottom of the bumps 19, relieving the pressure of the bumps 19 on the inner wall of the sleeve body 7, and facilitating the removal of the sleeve body 7 after cutting.

[0063] As Figure 7 shown, limiting plates 20 are fixedly connected to both sides of the bumps 19. The limiting plates 20 are slidably installed inside the inner shaft 18, and springs 21 are provided at the tops of the limiting plates 20.

[0064] When supporting the inside of the sleeve body 7, the connecting shaft 23 is located at the bottom end of the bumps 19. At this time, the springs 21 are deformed by the force to store elastic potential energy;

[0065] When the moving plate 17 moves outwards after cutting, the guiding ring 22 moves away from the bottom of the convex block 19, and the elastic potential energy is released by the spring 21, causing the convex block 19 to slide down into the inner shaft 18.

[0066] A method for using a cutting device for producing automotive sleeves includes the following steps:

[0067] S1: When the sleeve body 7 needs to be cut, first place the sleeve body 7 on the top of the two fixed bottom plates 6, and make the cutting point located below the cutting structure 3. Then start the motor 16. When the motor 16 starts, it drives the second rotating shaft 15 to rotate. The rotation of the second rotating shaft 15 drives the rotation of the second gear 14. The rotation of the second gear 14 drives the rotation of the first gear 13. The rotation of the first gear 13 drives the rotation of the first rotating shaft 11. When the first rotating shaft 11 rotates, it drives another first rotating shaft 11 to rotate synchronously through the second pulley group 12. When the first rotating shaft 11 rotates, it drives the first threaded rod 9 to rotate through the first pulley group 10. The rotation of the first threaded rod 9 drives the lifting plate 4 to move downwards. The movement of the lifting plate 4 drives the movement of the fixed top plate 5, so that the fixed top plate 5 moves to the top of the sleeve body 7 to cooperate with the fixed bottom plate 6 to fix it. The two fixed top plates 5 and the fixed bottom plates 6 are respectively located on both sides of the cutting structure 3 to fix both sides of the cutting point of the sleeve body 7.

[0068] S2: Then the second rotating shaft 15 continues to rotate to drive the third gear 34 to rotate. The rotation of the third gear 34 drives the rotation of the fourth rotating shaft 33. The rotation of the fourth rotating shaft 33 drives the rotation of the second bevel gear 32. The rotation of the second bevel gear 32 drives the rotation of the first bevel gear 31. The rotation of the first bevel gear 31 drives the rotation of the third rotating shaft 30. When the third rotating shaft 30 rotates, it drives the second threaded rod 28 to rotate through the third pulley group 29. When the second threaded rod 28 rotates, it drives the moving plate 17 to move. The movement of the moving plate 17 drives the movement of the inner shaft 18, so that the inner shaft 18 moves towards the side close to the cutting structure 3 and is embedded in the sleeve body 7.

[0069] S3: At the same time, the movement of the moving plate 17 drives the movement of the first magnetic block 26. When the first magnetic block 26 moves to one side of the second magnetic block 27, the two are magnetically connected, causing the first magnetic block 26 to move a certain distance towards the side of the second magnetic block 27. At the same time, the movement of the first magnetic block 26 drives the movement of the connecting plate 24. The movement of the connecting plate 24 drives the movement of the connecting shaft 23. The movement of the connecting shaft 23 drives the movement of the guiding ring 22. The movement of the guiding ring 22 pushes the convex block 19 upwards, so that the convex block 19 closely fits against the inner wall of the sleeve body 7 to support it.

[0070] S4: Then cut the sleeve body 7 through the cutting structure 3.

[0071] S5: After cutting, start the motor 16 again to reverse the second rotating shaft 15, so that the second gear 14 rotates to engage with the third gear 34 first, driving the two inner shafts 18 to move outward and slide out of the sleeve body 7. Then, the second gear 14 continues to rotate and engages with the first gear 13 to drive the two fixed top plates 5 to move upward and separate from the sleeve body 7, and the sleeve body 7 is taken out.

[0072] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.

Then start the motor (16). When the motor (16) starts, it drives the second rotating shaft (15) to rotate. The rotation of the second rotating shaft (15) drives the rotation of the second gear (14). The rotation of the second gear (14) drives the rotation of the first gear (13). The rotation of the first gear (13) drives the rotation of the first rotating shaft (11). When the first rotating shaft (11) rotates, it drives another first rotating shaft (11) to rotate synchronously through the second pulley group (12). When the first rotating shaft (11) rotates, it drives the first threaded rod (9) to rotate through the first pulley group (10). The rotation of the first threaded rod (9) drives the lifting plate (4) to move downward. The movement of the lifting plate (4) drives the movement of the fixed top plate (5), so that the fixed top plate (5) moves to the top of the sleeve body (7) to cooperate with the fixed bottom plate (6) to fix it. The two fixed top plates (5) and the fixed bottom plates (6) are respectively located on both sides of the cutting structure (3) to fix both sides of the cutting point of the sleeve body (7). S2: Then the second rotating shaft (15) continues to rotate to drive the third gear (34) to rotate. The rotation of the third gear (34) drives the rotation of the fourth rotating shaft (33). The rotation of the fourth rotating shaft (33) drives the rotation of the second bevel gear (32). The rotation of the second bevel gear (32) drives the rotation of the first bevel gear (31). The rotation of the first bevel gear (31) drives the rotation of the third rotating shaft (30). When the third rotating shaft (30) rotates, it drives the second threaded rod (28) to rotate through the third pulley group (29). When the second threaded rod (28) rotates, it drives the moving plate (17) to move. The movement of the moving plate (17) drives the movement of the inner shaft (18), so that the inner shaft (18) moves toward the side close to the cutting structure (3) and is embedded inside the sleeve body (7). S3: Meanwhile, the movement of the moving plate (17) drives the movement of the first magnetic block (26). When the first magnetic block (26) moves to one side of the second magnetic block (27), the two are magnetically connected, causing the first magnetic block (26) to move a certain distance towards one side of the second magnetic block (27). At the same time, the movement of the first magnetic block (26) drives the movement of the connecting plate (24), the movement of the connecting plate (24) drives the movement of the connecting shaft (23), the movement of the connecting shaft (23) drives the movement of the guiding ring (22), and the movement of the guiding ring (22) pushes the convex block (19) upwards, causing the convex block (19) to closely fit against the inner wall of the sleeve body (7) to support it; S4: Then, the sleeve body (7) is cut by the cutting structure (3); S5: After cutting, the motor (16) is started again to reverse the second rotating shaft (15), causing the second gear (14) to rotate and first engage with the third gear (34), driving the two inner shafts (18) to move outwards and slide out of the sleeve body (7). Then, the second gear (14) continues to rotate and engage with the first gear (13), driving the two fixed top plates (5) to move upwards and separate from the sleeve body (7), and the sleeve body (7) is taken out.
