Description

Technical Field

[0001] The invention relates to the technical field of shaft parts processing devices, in particular to a turning device for processing metal shaft parts. Background Art

[0002] When using machine tools to process small shaft parts, long metal rods are generally used for processing. After the machine tool completes processing the part, the machine tool continues to drive the metal rod and the part to rotate. The machine tool can then use a cutter to cut off the connection between the metal rod and the part. After cutting off the connection between the metal rod and the part, the machine tool will pull out another section of the metal rod and then process the next part.

[0003] When the machine tool cuts off the connection between the metal rod and the part, the metal rod and the part are in a rotating state. Therefore, when the part is disconnected, the part has great kinetic energy, which makes it easy for the part to be damaged by bumps when it falls. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention, by arranging a clamping assembly, a blanking assembly and a buffer assembly for use in conjunction, can enable the clamping assembly to clamp the metal shaft when the metal shaft is cut, so that the metal shaft will not fall directly when the metal shaft is cut, thereby avoiding the problem of the metal shaft with huge kinetic energy falling directly and being easily damaged.

[0015] 3. In the present invention, by using a buffer plate and a torsion spring in cooperation, the metal shaft falls into the material receiving groove through the material leakage hole. After the metal shaft that has fallen into the material receiving groove moves to a certain position and collides with the buffer plate, the buffer plate can rotate, converting the kinetic energy of the metal shaft into the elastic potential energy of the torsion spring for buffering, further avoiding damage to the metal shaft.

[0016] 4. In the present invention, by using an inclined groove and a knob in cooperation, the force of the torsion spring can be adjusted. After the torsion spring becomes loose due to long-term use, the knob can be rotated, and the rotating knob drives one end of the torsion spring to rotate, recharging the torsion spring.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Please refer to Figures 1-10 , a turning device for processing metal shaft parts, including a machine tool body 1, a guide rail 2 and a chuck 3. A frame body 4 is arranged on the guide rail 2, and one end of the frame body 4 is slidably connected with a sleeve 5. One end of the sleeve 5 penetrates through the frame body 4 and extends to the outside of the frame body 4. A clamping mechanism is arranged at one end of the sleeve 5 located outside the frame body 4. A material leakage hole 6 is opened on the lower surface of the sleeve 5, and the material leakage hole 6 communicates with the frame body 4. A strip-shaped groove 7 is opened on the upper surface of the sleeve 5, and a blanking component is arranged in the strip-shaped groove 7. A telescopic driving part is fixedly connected to one side side wall of the frame body 4. A receiving groove 9 is opened on one side side wall of the frame body 4, and a buffering component is arranged in the receiving groove 9.

[0021] It can be seen from the above structure that by setting the clamping component, the blanking component and the buffering component to be used in cooperation, when cutting the metal shaft, the clamping component can clamp the metal shaft. In this way, when the metal shaft is cut, the metal shaft will not directly fall, thereby avoiding the problem that the metal shaft with great kinetic energy directly falls and is easily damaged.

[0022] Furthermore, the clamping mechanism includes an electromagnet 10 fixedly sleeved at one end of the sleeve 5. One end of the sleeve 5 is rotatably connected with a rotating pipe 11. An annular cavity 12 is opened inside the rotating pipe 11, and a piston 13 is slidably connected to the inner wall of the annular cavity 12. A flexible sleeve 14 is fixedly connected to the inner wall of the rotating pipe 11, and a guide hole 15 communicating with the flexible sleeve 14 is opened on one side side wall of the rotating pipe 11. A connecting shaft 16 is fixedly connected to one side side wall of the piston 13, and a rotating ring 17 is fixedly connected to one end of the connecting shaft 16. An annular magnet 18 is rotatably sleeved at one end of the rotating ring 17. A first magnet sheet 19 is fixedly connected to one side side wall of the rotating pipe 11, and a second magnet sheet 20 is fixedly connected to one side side wall of the chuck 3. By setting the first magnet sheet 19 and the second magnet sheet 20 to be used in cooperation, before the clamping mechanism clamps the metal shaft, the clamping mechanism and the chuck 3 can complete magnetic coupling through the first magnet sheet 19 and the second magnet sheet 20, thereby making the clamping mechanism rotate. In this way, when the rotating clamping mechanism clamps the metal shaft, both are rotating, making the clamping mechanism and the metal shaft relatively stationary. Therefore, when the clamping mechanism clamps the metal shaft, there will be no mutual friction between it and the metal shaft, thereby protecting the outer wall of the metal shaft and preventing the outer wall of the metal shaft from being damaged due to friction.

[0023] Further, the telescopic driving member includes a cylinder 21 fixedly connected to the frame body 4, and the output end of the cylinder 21 is fixedly connected to the electromagnet 10; by providing the cylinder 21, the cylinder 21 can push the sleeve 5 to expand and contract.

[0024] Further, the blanking assembly includes a first magnet plate 8 slidably connected to the inner wall of the strip-shaped groove 7, and a long groove 22 is formed in one side wall of the strip-shaped groove 7. A limiting assembly is arranged in the long groove 22. A second magnet plate 23 is arranged on one side of the frame body 4, and a connecting rod 24 is fixedly connected to one side wall of the second magnet plate 23. One end of the connecting rod 24 is fixedly connected to the electromagnet 10; by providing the first magnet plate 8 and the second magnet plate 23 to cooperate with each other, when the cylinder 21 pushes the electromagnet 10 and the clamping mechanism to move towards one side of the metal shaft, the moving electromagnet 10 drives the second magnet plate 23 to move through the connecting rod 24, and the moving second magnet plate 23 drives the first magnet plate 8 to move through magnetism. After the first magnet plate 8 moves to a certain position, the limiting assembly blocks the first magnet plate 8 from continuing to move; After the metal shaft is cut off, the cylinder 21 drives the electromagnet 10 and the clamping mechanism to reset. After the clamping mechanism resets to a certain position, the first magnet piece 19 and the second magnet piece 20 are disengaged from magnetic coupling, so that the clamping mechanism can gradually stop rotating. When the clamping mechanism continues to move a certain position, the cut metal shaft contacts the first magnet plate 8. Subsequently, the electromagnet 10 is powered off. At this time, the first magnet plate 8 attracts the electromagnet 10, so that the first magnet plate 8 and the piston 13 are reset in the reverse direction. After the piston 13 is reset, the flexible sleeve 14 is reset, so that the flexible sleeve 14 releases the clamping of the metal shaft. At the same time, the cylinder 21 continues to drive the electromagnet 10 and the like to reset. After the electromagnet 10 resets to a certain position, the second magnet plate 23 moves above the first magnet plate 8. Subsequently, the continuously reset electromagnet 10 drives the first magnet plate 8 to move through the second magnet plate 23. The moving first magnet plate 8 attracts the metal shaft, so that the first magnet plate 8 drives the metal shaft to move. After the metal shaft moves to a certain position, the metal shaft falls into the material receiving groove 9 through the material leakage hole 6, and the blanking of the metal shaft can be completed.

[0025] Further, the limiting assembly includes a stopper 25 slidably connected to the long groove 22, and a fixing bolt 26 is threadedly connected to the inner wall of the stopper 25. One end of the fixing bolt 26 penetrates through the stopper 25 and abuts against the strip-shaped groove 7; by providing the stopper 25 and the fixing bolt 26 to cooperate with each other, after the first magnet plate 8 moves to a certain position, the stopper 25 can block the first magnet plate 8 from continuing to move.

[0026] Furthermore, the buffer assembly includes a buffer plate 27 disposed in the material receiving groove 9. One side wall of the buffer plate 27 is fixedly connected to a rotating rod 28. One end of the rotating rod 28 is rotatably connected to the material receiving groove 9. One side wall of the frame body 4 is fixedly connected to a fixed sleeve 30. One end of the rotating rod 28 penetrates through the material receiving groove 9 and extends into the fixed sleeve 30. One end of the rotating rod 28 located inside the fixed sleeve 30 is fixedly connected to a torsion spring 31. One end of the torsion spring 31 is fixedly connected to an adjusting assembly. By setting the buffer plate 27 and the torsion spring 31 to cooperate with each other, when the metal shaft falls into the material receiving groove 9 through the material leakage hole 6, after the metal shaft that has fallen into the material receiving groove 9 moves to a certain position and collides with the buffer plate 27, the buffer plate 27 can rotate, converting the kinetic energy of the metal shaft into the elastic potential energy of the torsion spring 31 for buffering, further avoiding the metal shaft from being bruised.

[0027] Furthermore, the adjusting assembly includes a knob 32 fixedly connected to the torsion spring 31. The knob 32 is rotatably connected to the fixed sleeve 30. A plurality of inclined grooves 33 are formed on the outer wall of the knob 32. A relief groove 34 is formed on the inner wall of the fixed sleeve 30. A spring piece 35 and an inclined block 36 are disposed in the relief groove 34. One end of the inclined block 36 penetrates through the relief groove 34 and extends into the inclined groove 33. By setting the inclined groove 33 and the knob 32 to cooperate with each other, the force of the torsion spring 31 can be adjusted. After the torsion spring 31 becomes loose due to long-term use, the knob 32 can be rotated. The rotating knob 32 drives one end of the torsion spring 31 to rotate, recharging the torsion spring 31.

[0028] Furthermore, a limiting hole is formed on one side wall of the sleeve 5. A limiting post 29 is slidably connected to the inner wall of the limiting hole. One end of the limiting post 29 is fixedly connected to the frame body 4. By setting the limiting post 29, the sleeve 5 can be limited, thereby increasing the stability of the sleeve 5 during movement.

[0029] In the present invention, during use, when the machine tool body 1 cuts off the connection of the metal shaft, the air cylinder 21 pushes the electromagnet 10 and the clamping mechanism to move towards one side of the metal shaft, so that the clamping mechanism sleeves on the outer wall of the metal shaft. When the clamping mechanism approaches the chuck 3, the clamping mechanism and the chuck 3 complete magnetic coupling through the first magnet sheet 19 and the second magnet sheet 20. In this way, the rotating chuck 3 will drive the clamping mechanism to rotate. Subsequently, the electromagnet 10 is activated, and the annular magnet 18 moves due to the repulsion of the electromagnet 10. Thus, the annular magnet 18 pushes the rotating ring 17, the connecting shaft 16 and the piston 13 to move. The moving piston 13 pushes the medium in the annular cavity 12 into the flexible sleeve 14, causing the flexible sleeve 14 to expand, and thus the flexible sleeve 14 clamps the metal shaft. When the connection of the metal shaft is cut off, the metal shaft will not directly fall down, thereby avoiding the problem that the metal shaft may be bruised due to direct falling. When the cylinder 21 pushes the electromagnet 10 and the clamping mechanism to move towards one side of the metal shaft, the moving electromagnet 10 drives the second magnet plate 23 to move through the connecting rod 24. The moving second magnet plate 23 drives the first magnet plate 8 to move through magnetism. After the first magnet plate 8 moves to a certain position, the limiting component blocks the first magnet plate 8 from continuing to move; After the metal shaft is cut off, the cylinder 21 drives the electromagnet 10 and the clamping mechanism to reset. After the clamping mechanism resets to a certain position, the first magnet piece 19 and the second magnet piece 20 are disengaged from magnetic coupling, so that the clamping mechanism can gradually stop rotating. When the clamping mechanism continues to move a certain position, the cut metal shaft contacts the first magnet plate 8. Subsequently, the electromagnet 10 is powered off. At this time, the first magnet plate 8 attracts the electromagnet 10, so that the first magnet plate 8 and the piston 13 are reset in the reverse direction. After the piston 13 is reset, the flexible sleeve 14 is reset, so that the flexible sleeve 14 releases the clamping of the metal shaft. At the same time, the cylinder 21 continues to drive the electromagnet 10 and the like to reset. After the electromagnet 10 resets to a certain position, the second magnet plate 23 moves above the first magnet plate 8. Subsequently, the continuously resetting electromagnet 10 drives the first magnet plate 8 to move through the second magnet plate 23. The moving first magnet plate 8 attracts the metal shaft, so that the first magnet plate 8 drives the metal shaft to move. After the metal shaft moves to a certain position, the metal shaft falls into the material receiving groove 9 through the material leakage hole 6. When the metal shaft falling into the material receiving groove 9 moves to a certain position and collides with the buffer plate 27, the buffer plate 27 can rotate to convert the kinetic energy of the metal shaft into the elastic potential energy of the torsion spring 31 for buffering, further avoiding the metal shaft from being damaged.
