Description

Technical Field

[0001] The present invention relates to the technical field of machining, and specifically to a fully automatic spline shaft quenching processing device. Background Art

[0002] Spline shaft quenching is an important metal heat treatment process, mainly used to improve the hardness, strength and wear resistance of the spline shaft. Spline shaft quenching heats the spline shaft rapidly through a high-frequency induction heating device to make its surface reach the quenching temperature, and then rapidly cools its surface to below the quenching temperature through rapid cooling (such as water spraying cooling) to achieve the hardening effect. At present, some devices use a manipulator to achieve automatic loading and unloading, realizing the automation of quenching processing.

[0003] During the quenching process of the spline shaft, it is necessary to drive the spline shaft to rotate through upper and lower centers to achieve uniform heating and cooling. However, the cooling water directly sprays onto the surface of the spline shaft, which is easy to splash everywhere. The splashing cooling water may carry pollutants such as oil and impurities, polluting the equipment. Moreover, the direct discharge of the steam generated during quenching may cause condensation or corrosion inside the quenching equipment, affecting the performance and service life of the equipment. The generated steam contains elements such as carbon, sulfur, and nitrogen, and direct discharge also pollutes the workshop environment. Summary of the Invention

And with the cooperation of the horizontal column, the second gear, and the second rack, the outer cylinder is driven to rise. At the same time, by using the rising action of the outer cylinder and in combination with the action of the fourth gear, the third gear, and the tooth track, the sealing cover is closed, forming a relatively sealed space above the quenching processing position.

And the top of the telescopic shaft 15 is connected with the transmission column 13 through bevel gears. When the driving motor 12 is started, its output shaft drives the transmission column 13 to rotate. Then the transmission column 13 drives the telescopic shaft 15 to rotate through bevel gears. The top of the telescopic shaft 15 is fixed to the bottom of the lower center 19. The telescopic shaft 15 drives the lower center 19 to rotate. Inner cylinders 20 are bolted on both sides of the top of the connecting seat 14. A fixing seat 16 is bolted inside the inner cylinder 20.

[0042] The lifting control mechanism 27 includes a main pipe 271, a long cylinder 272 and a piston 273. The long cylinder 272 communicates with the main pipe 271. The other end of the main pipe 271 is connected to a supply pump and a chiller for transporting cooling water. The piston 273 is slidably connected to the inner wall of the long cylinder 272. A delivery pipe 2715 is communicated with the surface of the long cylinder 272 away from the main pipe 271. A plurality of connecting pipes 2716 are communicated with the surface of the delivery pipe 2715. One end of the connecting pipe 2716 away from the delivery pipe 2715 penetrates to the inside of the inner cylinder 20 and communicates with the annular ring 25. Under the action of the connecting pipe 2716, the delivery pipe 2715 is connected to the annular ring 25. A fixing rod 276 is also bolted to one side of the horizontal frame 10. A sliding sleeve 277 is bolted to the top of the fixing rod 276. A movable rod 275 is slidably connected to the inner wall of the sliding sleeve 277. The other end of the movable rod 275 extends into the inside of the long cylinder 272 and is fixed to the piston 273. A circular plate 274 is also bolted to the surface of the movable rod 275. A compression spring 278 is fixed to the surface of the circular plate 274. The other end of the compression spring 278 is fixed to the surface of the sliding sleeve 277. The compression spring 278 is sleeved on the surface of the movable rod 275. A first rack 279 is also fixed to one side of the surface of the circular plate 274 through a connecting rod. The lifting control mechanism 27 further includes a vertical plate 2710 bolted to the inside of the machine shell 1. A horizontal column 2711 is rotatably connected to the surface of the vertical plate 2710. A first gear 2712 is fixed to one end of the horizontal column 2711. The first gear 2712 meshes with the first rack 279. A plurality of second gears 2713 are also fixed to the surface of the horizontal column 2711. Cross bars 2714 are bolted to both sides of the surface of the outer cylinder 21. A second rack 2719 is bolted to the other end of the cross bar 2714. The second rack 2719 meshes with the second gear 2713. Drain pipes 2717 are communicated with both sides of the bottom of the inner cylinder 20. One end of the drain pipe 2717 away from the inner cylinder 20 is communicated with a lower pipe 2718. One end of the lower pipe 2718 is communicated with the water storage tank 8. The cooling water can flow into the inside of the water storage tank 8 through the inner cylinder 20, the drain pipe 2717 and the lower pipe 2718 for temporary storage.

[0043] During operation, first, the first manipulator 5 moves to grasp the spline shaft on the first conveying device 2 and moves along the transverse track 4 to move the spline shaft between the upper center 35 and the lower center 19 and to the processing position. Then, the upper center 35 descends to cooperate with the lower center 19 to fix the spline shaft up and down, realizing automatic feeding. Then the manipulator moves away. At this time, the spline shaft passes through the heating coil body 18, and heating of the spline shaft begins. At the same time, the high-pressure supply pump connected to the main pipe 271 is turned on, and cold water is conveyed through the main pipe 271. When the cold water enters the interior of the long cylinder 272, it pushes the piston 273 forward. The piston 273 drives the movable rod 275 and the circular plate 274 to move forward together, causing the circular plate 274 to approach the sliding sleeve 277 and compressing the compression spring 278. After that, when the piston 273 passes through the inlet at the connection between the conveying pipe 2715 and the long cylinder 272, the cold water enters through the conveying pipe 2715, and the cold water no longer exerts pressure on the piston 273, so the piston 273 stops moving. During the forward movement of the circular plate 274, it can drive the first rack 279 to move. The first rack 279 drives the transverse column 2711 to rotate clockwise through the first gear 2712, thereby driving the second gear 2713 on its surface to rotate clockwise together. The second gear 2713 drives the second rack 2719 to rise, and drives the cross bar 2714 and the outer cylinder 21 to rise to cover the inlet of the inner cylinder 20. Moreover, at this time, both the first manipulator 5 and the second manipulator 6 are far away from the processing position and will not affect the rising of the outer cylinder 21.

[0044] The opening and closing control mechanism 28 includes a long plate 281, a third gear 282 and a support plate 283. The long plate 281 is bolted to the surface of the lower connecting plate 23. A transmission rod 286 is fixed to the top of the long plate 281 through a bearing seat. One end of the transmission rod 286 is connected to the rotating shaft 24 on one side through a bevel gear transmission. The other end of the transmission rod 286 is bolted to the fourth gear 284. The number of support plates 283 is two groups and they are respectively fixed above the top of the water tank 8 and the transverse frame 10. A toothed track 285 is bolted to the surface of the support plate 283, and the fourth gear 284 is meshed with the toothed track 285. The third gear 286 is connected to the rotating shaft 24 on one side through a bevel gear transmission. The fourth gear 284 is meshed with the toothed track 285. There are two groups of gears 82, which are respectively fixed on the surfaces of the rotating shafts 24 on both sides and mesh with each other. During the rising process of the outer cylinder 21, the connecting plate 23, the long plate 281, the transmission rod 286 and the fourth gear 284 can be driven to rise together. The fourth gear 284 rises along the surface of the tooth track 285 and drives the transmission rod 286 to rotate. The transmission rod 286 drives the rotating shaft 24 on one side to rotate through the bevel gear, and then the rotating shaft 24 on the side drives the other group of rotating shafts 24 to rotate through the two groups of third gears 282. The rotating shafts 24 on both sides rotate synchronously, driving the upper sealing covers 22 to approach each other, sealing The cover 22 is designed as a whole in a semi-arc shape, and a groove 31 is provided on the surface of the sealing cover 22. The inner wall of the groove 31 is designed in an arc shape. The sealing cover 22 areas on both sides are closed loops, and the top of the outer cylinder 21 is sealed to prevent a large amount of steam from escaping. In addition, the design of the groove 31 can provide space for the spline shaft to pass through during the processing. After passing through the delivery pipe 2715 and the connecting pipe 2716, the cold water enters the interior of the annular ring 25, and the nozzle 26 sprays cold water onto the surface of the spline shaft to be processed to cool it down and perform quenching processing. At the same time, the drive motor 12 is turned on to drive the transmission column 13 to rotate, and the transmission column 13 The telescopic shaft 15 and the lower center 19 are driven to rotate by the bevel gear, thereby driving the processed spline shaft to rotate and performing a comprehensive quenching process. At this time, under the action of the inner cylinder 20, the outer cylinder 21 and the sealing cover 22, a relatively sealed space is formed, water will not splash everywhere, and steam will not escape in large quantities. The generated waste water passes through the discharge pipe 2717 and the lower pipe 2718 and enters the water storage tank 8 for temporary storage. The length of the tooth track 285 is greater than the up and down movement range of the outer cylinder 21, which ensures that the fourth gear 284 will not be separated from the surface of the tooth track 285 when following the up and down movement of the outer cylinder 21.

[0045] The inhalation mechanism 29 includes a hose 291, a blower 292 and a stop block 293. One end of the hose 291 is in communication with the outer cylinder 21, and the other end of the hose 291 is in communication with the transverse channel 7. The stop block 293 is bolted to the lower part inside the transverse channel 7. When the blower 292 is turned on, a negative pressure is generated inside the transverse channel 7, which causes the steam inside the outer cylinder 21 and the inner cylinder 20 to enter the inside of the transverse channel 7 through the hose 291. The spraying mechanism 30 includes a pump body 301, an impeller 302 and a suction pipe 303. The pump body 301 is bolted to the top of the water storage tank 8. The impeller 302 is rotatably connected to the inside of the pump body 301. The rotating shaft of the impeller 302 extends to the outside and is connected to the transmission column 13 through gear transmission. A vertical plate 308 is also bolted to the top of the water storage tank 8, and the transmission column 13 is rotatably connected to the surface of the vertical plate 308 to increase the rotational stability of the other end of the transmission column 13. One end of the suction pipe 303 is in communication with the inlet end of the pump body 301, and the other end of the suction pipe 303 extends to the lower part inside the water storage tank 8. The outlet end of the pump body 301 is connected with a delivery pipe 304. A transverse pipe 305 is arranged above the transverse channel 7, and the other end of the delivery pipe 304 is in communication with the transverse pipe 305. A plurality of spray nozzles 306 are connected to the bottom of the transverse pipe 305 through pipes. The spray nozzles 306 are located inside the transverse channel 7. During the rotation of the transmission column 13, it can drive the impeller 302 to rotate through gears. The rotation of the impeller 302 generates centrifugal force, forming a negative pressure, similar to the principle of the impeller of a centrifugal water pump. It causes the waste water inside the water storage tank 8 to be sprayed into the inside of the transverse channel 7 by the spray nozzles 306 after passing through the suction pipe 303, the pump body 301, the delivery pipe 304 and the transverse pipe 305. When the steam passes through the inside of the transverse channel 7, water is sprayed on the surface of the steam. The recovered waste water is used as an absorbent to absorb elements such as carbon, sulfur, nitrogen, etc. in the steam, and the water vapor is also cooled, directly avoiding the emission of hot steam. After the waste water is absorbed, a vertical pipe 307 is also connected to the bottom of the transverse channel 7, and the bottom of the vertical pipe 307 is in communication with the water storage tank 8, and the waste water can return to the inside of the water storage tank 8 again. A waste water pump 32 is also connected to one side of the water storage tank 8. The outlet end of the waste water pump 32 is connected with a waste water discharge pipe 33. A liquid level sensor 36 is also arranged above the inside of the water storage tank 8. The liquid level sensor 36 is externally connected to the main control system (PLC controller) of the device, and the waste water pump 32 is also connected to the main control system. The waste water discharge pipe 33 is connected to the subsequent waste water treatment equipment. As the processing operation continues and waste water enters, when the water level of the waste water inside the water storage tank 8 touches the liquid level sensor 36, the waste water pump 32 is turned on, and the waste water is discharged into the subsequent waste water treatment equipment through the waste water discharge pipe 33. The setting of the stop block 293 can prevent waste water from entering the hose 291.

[0046] After the spline shaft is processed, the chiller stops supplying water, and there is a lack of water pressure inside the main pipe 271. The piston 273 and the movable rod 275 are reset under the action of the compression spring 278, so as to drive the transverse column 2711 to rotate counterclockwise through the first rack 279 and the first gear 2712, and drive the second rack 2719 and the outer cylinder 21 to descend. At the same time, the outer cylinder 21 drives the fourth gear 284 to descend, and under the action of the transmission rod 286, the third gear 282 and the rotating shaft 24, the sealing covers 22 on both sides are opened, exposing the top of the outer cylinder 21. Moreover, the height of the outer cylinder 21 at this time is lower than the height of the top of the inner cylinder 20, preventing interference with the second manipulator 6 from grasping the spline shaft after quenching processing.
