[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.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention, by providing 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. In this way, 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] 2. The present invention sets a first magnet sheet and a second magnet sheet for use in conjunction with each other. Before the clamping mechanism clamps the metal shaft, the clamping mechanism and the chuck can complete magnetic coupling through the first magnet sheet and the second magnet sheet, thereby causing the clamping mechanism to rotate. In this way, the rotating clamping mechanism and the metal shaft both rotate when clamping, so that the clamping mechanism and the metal shaft are relatively stationary. 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 so that the outer wall of the metal shaft will not be damaged by friction.

[0016] 3. The present invention sets a buffer plate for use in conjunction with a torsion spring, etc., and the metal shaft falls into the receiving trough through the leakage hole. After the metal shaft dropped into the receiving trough moves to a certain position, when the metal shaft collides with the buffer plate, the buffer plate can rotate to convert the kinetic energy of the metal shaft into the elastic potential energy of the torsion spring for buffering, thereby further preventing the metal shaft from being damaged.

[0017] 4. The present invention can adjust the force of the torsion spring by providing an inclined groove and a knob. When the torsion spring becomes loose due to long-term use, the knob can be rotated. The rotating knob drives one end of the torsion spring to rotate, thereby recharging the torsion spring.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figures 1-10 A turning device for processing metal shaft parts includes a machine tool body 1, a guide rail 2 and a chuck 3. A frame 4 is provided on the guide rail 2, and one end of the frame 4 is slidably connected to a sleeve 5. One end of the sleeve 5 passes through the frame 4 and extends to the outside of the frame 4. A clamping mechanism is provided at one end of the sleeve 5 located outside the frame 4. A leakage hole 6 is provided on the lower surface of the sleeve 5, and the leakage hole 6 is connected to the frame 4. A strip groove 7 is provided on the upper surface of the sleeve 5, and a blanking assembly is provided in the strip groove 7. A telescopic driving member is fixedly connected to one side wall of the frame 4. A receiving groove 9 is provided on one side wall of the frame 4, and a buffer assembly is provided in the receiving groove 9.

[0031] It can be seen from the above structure that: by setting up the clamping assembly, the blanking assembly and the buffer assembly for use together, the clamping assembly can clamp the metal shaft when cutting the metal shaft, 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.

[0032] Furthermore, the clamping mechanism includes an electromagnet 10 fixedly sleeved on one end of the sleeve 5, and one end of the sleeve 5 is rotatably connected to a rotating tube 11, an annular cavity 12 is provided inside the rotating tube 11, and a piston 13 is slidably connected to the inner wall of the annular cavity 12, the inner wall of the rotating tube 11 is fixedly connected to a flexible sleeve 14, and a guide hole 15 communicating with the flexible sleeve 14 is provided on one side wall of the rotating tube 11, one side wall of the piston 13 is fixedly connected to a connecting shaft 16, and one end of the connecting shaft 16 is fixedly connected to a rotating ring 17, one end of the rotating ring 17 is rotatably sleeved with an annular magnet 18, one side wall of the rotating tube 11 is fixedly connected to a first magnet piece 19, and the chuck A second magnet piece 20 is fixedly connected to one side wall of 3; by arranging the first magnet piece 19 and the second magnet piece 20 for use in conjunction with each other, before the clamping mechanism clamps the metal shaft, the clamping mechanism and the chuck 3 can complete magnetic coupling through the first magnet piece 19 and the second magnet piece 20, thereby causing the clamping mechanism to rotate. In this way, the rotating clamping mechanism and the metal shaft are both rotating when clamping, so that the clamping mechanism and the metal shaft are relatively stationary, and then 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 so that the outer wall of the metal shaft will not be damaged by friction.

[0033] Furthermore, the telescopic driving member includes a cylinder 21 fixedly connected to the frame 4, and the output end of the cylinder 21 is fixedly connected to the electromagnet 10; by setting the cylinder 21, the cylinder 21 can push the sleeve 5 to extend and retract.

[0034] Furthermore, the blanking assembly includes a first magnet plate 8 that is slidably connected to the inner wall of the strip groove 7, and a long groove 22 is opened on one side wall of the strip groove 7, and a limit assembly is arranged in the long groove 22, and a second magnet plate 23 is arranged on one side of the frame 4, and a connecting rod 24 is fixedly connected to one side wall of the second magnet plate 23, and one end of the connecting rod 24 is fixedly connected to the electromagnet 10; by setting the first magnet plate 8 and the second magnet plate 23 for use in conjunction with each other, when the cylinder 21 pushes the electromagnet 10 and the clamping mechanism to move toward 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 limit assembly prevents the first magnet plate 8 from continuing to move;

[0035] After the metal shaft is cut, the cylinder 21 drives the electromagnet 10 and the clamping mechanism to reset. After the clamping mechanism is reset to a certain position, the first magnet piece 19 and the second magnet piece 20 are disconnected from the magnetic coupling, so that the clamping mechanism can gradually stop rotating. When the clamping mechanism continues to move to a certain position, the cut metal shaft contacts the first magnet plate 8. Then 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 opposite direction. After the piston 13 is reset, the flexible sleeve 14 is reset, so that the flexible sleeve 14 is reset. The sex sleeve 14 releases the clamping of the metal shaft, and at the same time, the cylinder 21 continues to drive the electromagnet 10 to reset. After the electromagnet 10 is reset to a certain position, the second magnet plate 23 moves to the top of the first magnet plate 8, and then the electromagnet 10 that continues to reset drives the first magnet plate 8 to move through the second magnet plate 23. The moving first magnet plate 8 attracts the metal shaft, and then the first magnet plate 8 moves with the metal shaft. After the metal shaft moves to a certain position, the metal shaft falls into the receiving trough 9 through the leakage hole 6, and the unloading of the metal shaft can be completed.

[0036] Furthermore, the limiting assembly includes a stopper 25 slidably connected to the long slot 22, and the inner wall of the stopper 25 is threadedly connected to a fixing bolt 26, one end of the fixing bolt 26 passes through the stopper 25 and abuts against the strip slot 7; by setting the stopper 25 and the fixing bolt 26 for use in conjunction with each other, the stopper 25 can prevent the first magnet plate 8 from continuing to move after the first magnet plate 8 moves to a certain position.

[0037] Furthermore, the buffer assembly includes a buffer plate 27 arranged in the material receiving trough 9, and a rotating rod 28 is fixedly connected to a side wall of one side of the buffer plate 27, one end of the rotating rod 28 is rotatably connected to the material receiving trough 9, and a fixed sleeve 30 is fixedly connected to a side wall of the frame body 4, and one end of the rotating rod 28 passes through the material receiving trough 9 and extends to the inside of 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, and one end of the torsion spring 31 is fixedly connected to an adjustment assembly; by setting the buffer plate 27 and using it in conjunction with the torsion spring 31, the metal shaft falls into the material receiving trough 9 through the leakage hole 6. After the metal shaft dropped into the material receiving trough 9 moves to a certain position, when the metal shaft collides with the buffer plate 27, the buffer plate 27 can rotate to convert the kinetic energy of the metal shaft into elastic potential energy of the torsion spring 31 for buffering, thereby further preventing the metal shaft from being damaged.

[0038] Furthermore, the adjustment component includes a knob 32 fixedly connected to the torsion spring 31, and the knob 32 is rotatably connected to the fixed sleeve 30. The outer wall of the knob 32 is provided with a plurality of inclined grooves 33, and the inner wall of the fixed sleeve 30 is provided with a clearance groove 34, and a spring piece 35 and an inclined block 36 are provided in the clearance groove 34, and one end of the inclined block 36 passes through the clearance groove 34 and extends to the interior of the inclined groove 33; by setting the inclined groove 33 and using it in conjunction with the knob 32, 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, and the rotating knob 32 drives one end of the torsion spring 31 to rotate, thereby recharging the torsion spring 31.

[0039] Furthermore, a limiting hole is opened on one side wall of the sleeve 5, and the inner wall of the limiting hole is slidably connected to the limiting column 29, and one end of the limiting column 29 is fixedly connected to the frame 4; by setting the limiting column 29, the sleeve 5 can be limited, thereby increasing the stability of the sleeve 5 when moving.

[0040] In the present invention, when in use, when the machine tool body 1 cuts off the connection of the metal shaft, the cylinder 21 pushes the electromagnet 10 and the clamping mechanism to move toward one side of the metal shaft, so that the clamping mechanism is sleeved on the outer wall of the metal shaft. When the clamping mechanism is close to the chuck 3, the clamping mechanism and the chuck 3 are magnetically coupled through the first magnet piece 19 and the second magnet piece 20. In this way, the rotating chuck 3 will drive the clamping mechanism to rotate, and then the electromagnet 10 is started, and the annular magnet 18 is repelled by the electromagnet 10 and moves, thereby causing the annular magnet 18 to push 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 then the flexible sleeve 14 clamps the metal shaft. This is because when the connection of the metal shaft is cut off, the metal shaft will not fall down directly, thereby avoiding the problem of the metal shaft falling directly and being damaged.

[0041] When the cylinder 21 pushes the electromagnet 10 and the clamping mechanism to move toward one side of the metal shaft, the moving electromagnet 10 drives the second magnet plate 23 to move via the connecting rod 24. The moving second magnet plate 23 drives the first magnet plate 8 to move via magnetism. After the first magnet plate 8 moves to a certain position, the limit assembly prevents the first magnet plate 8 from continuing to move.

[0042] After the metal shaft is cut, the cylinder 21 drives the electromagnet 10 and the clamping mechanism to reset. After the clamping mechanism is reset to a certain position, the first magnet piece 19 and the second magnet piece 20 are disconnected from the magnetic coupling, so that the clamping mechanism can gradually stop rotating. When the clamping mechanism continues to move to a certain position, the cut metal shaft contacts the first magnet plate 8. Then 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 opposite 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 to reset. After 0 is reset to a certain position, the second magnet plate 23 moves to the top of the first magnet plate 8, and then the electromagnet 10 that continues to reset drives the first magnet plate 8 to move through the second magnet plate 23. The moving first magnet plate 8 attracts the metal shaft, and then the first magnet plate 8 moves with the metal shaft. After the metal shaft moves to a certain position, the metal shaft falls into the receiving trough 9 through the leakage hole 6. After the metal shaft that falls into the receiving trough 9 moves to a certain position, when the metal shaft 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, thereby further preventing the metal shaft from being damaged.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
