Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a full-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 spline shafts. Spline shaft quenching uses high-frequency induction heating equipment to quickly heat the spline shaft to the quenching temperature, and then quickly cools the surface to below the quenching temperature through rapid cooling (such as water spray cooling), thereby achieving a hardening effect. At present, some equipment uses robots to realize automatic loading and unloading, realizing the automation of quenching processing.

[0003] During the quenching process of the spline shaft, the upper and lower centers are required to drive the spline shaft to rotate to achieve uniform heating and cooling. However, the cooling water is sprayed directly 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, causing pollution to the equipment. In addition, the direct discharge of the steam generated by quenching may cause condensation or corrosion inside the quenching equipment, affecting the performance and 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

[0022] During operation, the first manipulator 5 moves first, grabs the spline shaft on the first conveying device 2, and moves along the transverse track 4, moves the spline shaft to between the upper center point 35 and the lower center point 19, moves to the processing position, and then the upper center point 35 descends and cooperates with the lower center point 19 to fix the spline shaft up and down to realize automatic loading, and then the manipulator moves away. At this time, the spline shaft passes through the heating ring body 18 and starts to heat the spline shaft. At the same time, the high-pressure supply pump external to the main pipe 271 is turned on, and cold water is transported through the main pipe 271. When the cold water enters the interior of the long cylinder 272, the piston 273 is pushed forward, and the piston 273 drives the movable rod 275 and the circular plate 274 to move forward together, so that the circular plate 274 approaches the direction of the sliding sleeve 277 and makes the compression spring 278 in The piston 273 is in a compressed state. When the piston 273 passes through the entrance of the connection between the delivery pipe 2715 and the long cylinder 272, cold water enters through the delivery pipe 2715. The cold water no longer applies pressure to the piston 273, and the piston 273 stops moving. In the process of moving forward, the circular plate 274 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 the surface to rotate clockwise. The second gear 2713 drives the second rack 2719 to rise, and drives the cross bar 2714 and the outer cylinder 21 to rise, covering the entrance of the inner cylinder 20. At this time, 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.

[0023] 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.

[0024] The suction mechanism 29 includes a hose 291, a fan 292 and a stopper 293. One end of the hose 291 is interconnected with the outer cylinder 21, and the other end of the hose 291 is interconnected with the transverse channel 7. The stopper 293 is bolted to the lower part of the inside of the transverse channel 7. When the fan 292 is turned on, negative pressure is generated inside the transverse channel 7, which allows the steam inside the outer cylinder 21 and the inner cylinder 20 to enter the inside of the transverse channel 7 after passing through the hose 291. The spray 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, and 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 communicates with the transmission column 13. The top of the water tank 8 is also bolted with a vertical plate 308 through a gear transmission connection, 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 connected to the inlet end of the pump body 301, and the other end of the suction pipe 303 extends to the bottom of the water tank 8. The outlet end of the pump body 301 is connected with a delivery pipe 304, and a transverse pipe 305 is provided above the transverse channel 7, and the other end of the delivery pipe 304 is connected to the transverse pipe 305. The bottom of the transverse pipe 305 is connected through a pipeline and provided with a plurality of nozzles 306. The nozzles 306 are located inside the transverse channel 7. During the rotation of the transmission column 13, they can be connected through The impeller 302 is driven to rotate by the gears. The rotation of the impeller 302 generates centrifugal force and forms negative pressure, which is similar to the principle of the impeller of a centrifugal water pump. The waste water in the water storage tank 8 passes through the suction pipe 303, the pump body 301, the delivery pipe 304, and the transverse pipe 305, and then is sprayed out to the inside of the transverse channel 7 by the nozzle 306. When the steam passes through the inside of the transverse channel 7, the water is sprayed on the surface of the steam. The recovered waste water is used as an absorbent to absorb carbon, sulfur, nitrogen and other elements in the steam, and the water vapor is also cooled to directly avoid the discharge of hot steam. After the waste water is absorbed, the bottom of the transverse channel 7 is also connected to a vertical pipe 307, and the bottom of the vertical pipe 307 is connected to the water storage tank 8. The waste water is It can return to the interior of the water tank 8. A waste pump 32 is also connected to one side of the water tank 8. The outlet end of the waste pump 32 is connected to a waste pipe 33. A liquid level sensor 36 is also arranged above the interior of the water tank 8. The liquid level sensor 36 is connected to the main control system (plc controller) of the external device. The waste pump 32 is also connected to the main control system. The waste pipe 33 is connected to the subsequent wastewater treatment equipment. As the processing operation continues, wastewater enters. When the water level of the wastewater in the water tank 8 contacts the liquid level sensor 36, the waste pump 32 is turned on, and the wastewater is discharged into the subsequent wastewater treatment equipment through the waste pipe 33. The setting of the block 293 can prevent the wastewater from entering the hose 291.

[0025] After the spline shaft is processed, the water supply of the chiller stops, 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, thereby driving the transverse column 2711 to rotate counterclockwise through the first rack 279 and the first gear 2712, and driving 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 to expose the top of the outer cylinder 21. At this time, the height of the outer cylinder 21 is lower than the height of the top of the inner cylinder 20 to prevent the second manipulator 6 from grabbing the spline shaft after quenching. Then the upper center 35 rises, and the second manipulator 6 transfers the spline shaft to the second conveying equipment 3 to complete the processing.
