Description

Technical Field

[0001] This invention relates to the field of lathe loading and unloading technology, specifically to an automatic loading and unloading conveying device for lathes and its usage method. Background Technology

[0002] A lathe is a machine tool primarily used to machine rotating workpieces using a cutting tool. It is the most important type of metal cutting machine tool, and is the most numerous and prevalent type in general machine manufacturing plants; it is also known as the "mother machine." Drills, reamers, taps, dies, and knurling tools can also be used on lathes for various machining operations. The function of a lathe is to cut rotating surfaces of various sizes and shapes, as well as helical surfaces.

[0003] The existing flange processing first requires forging a disc-shaped blank, then turning and drilling the forged disc-shaped blank, and only after passing inspection can it be put into storage or shipped.

[0004] The existing flange lathe machining and loading / unloading technology has the following shortcomings: 1. Generally, the flange is placed manually into the chuck of the lathe. After the chuck positions the flange, one end face of the flange is machined first. Then the machine needs to be stopped, the flange is rotated 180 degrees and clamped back into the chuck, and the other end face is machined. The circumferential surface of the flange also needs to be machined. Then drilling is performed. Then the machine is stopped and the machined flange is removed manually. During the processing, the loading and unloading of the flange and the flipping of the machined surface all need to be done manually, which results in a high degree of human involvement. This not only increases labor costs, but also poses certain safety hazards because workers frequently come into direct contact with the lathe. 2. Dust or metal shavings are easily adhering to the outer wall of the freshly forged flange blank. If it is not cleaned and directly turned or drilled, the dust and metal shavings will damage the cutting tools and reduce the assembly accuracy of the flange, thereby reducing the machining accuracy and increasing the scrap rate.

[0015] A method of using an automatic loading and unloading conveyor for a lathe includes the following steps: S1: Flange loading: This equipment is equipped with a controller, and all electrical devices on the equipment are electrically connected to the controller. When processing flanges, firstly, the controller activates the electric push rod on the right side of the top of the base, causing its output end to extend upwards. This, in turn, drives the movable support rod upwards via the first slider. Then, the flanges are fitted one by one between the movable support rod and the three fixed support rods, ensuring that one end of the first flange being fed is in contact with several rubber stops. This continues until the space between the movable support rod and the three fixed support rods is filled with flanges, indicating that the flange feeding is complete. Then, the controller retracts the output end of the electric push rod, which in turn drives the movable support rod to reset via the first slider. The movable support rod and the three fixed support rods provide support for the inner rings of all flanges.

[0016] S2: Flange cutting: After the anti-rust oil applied to the flange has solidified, the electric push rod on the left side of the top of the base is activated by the controller, causing its output end to extend upward. This, in turn, drives another movable support rod to slide upward via another first slider. This allows the worker to easily grasp the flange on the left side of the top of the base and simultaneously pull it away from the bearing plate during the upward lifting process, until the oiled flange is removed from the left side of the top of the base, thus completing the unloading process.

[0017] S3: Flange clamping, turning, and drilling: After the movable support rod and three fixed support rods on the right side of the top of the base provide support for the inner rings of all flanges, the servo motor is started by the controller, so that its output end rotates. Since each synchronous pulley is rotatably connected to one end of the mounting frame through the first rotating shaft, the output end of the servo motor is fixedly connected to the end of one of the first rotating shafts through the coupling. The two synchronous pulleys are sleeved by the synchronous belt, the connecting block is fixedly connected to the synchronous belt, the second slide plate is slidably connected to the guide rail, and the second slide plate and the connecting block are both fixedly connected to the lead screw slide table. The second slider is slidably mounted on the lead screw slide table, thereby driving the second slider to slide towards the end of the material rack on the right side of the top of the base.

[0018] When the second slider slides towards the end of the material rack near the top right of the base until the two grippers are aligned with the first flange on the material rack at the top right of the base, the servo motor is first powered off by the controller, causing the two grippers to stop sliding. Then, the stepper motor is started by the controller, causing its output end to drive the turntable. Since the adapter plate is fixedly connected to the bottom of the second rotating shaft, and the mounting rod is fixedly connected to the bottom of the adapter plate, each T-shaped slide bar is slidably connected to a T-slot, and each centering plate is fixedly connected to the bottom of a T-shaped slide bar. The turntable and a centering plate are respectively hinged to the two ends of a connecting rod. Each gripper... Each jaw is fixedly connected to a centering plate, which causes the two jaws to move closer together and clamp the first flange located on the far left of the material rack. Then, the sliding assembly drives the two jaws and the clamped first flange to slide towards the end of the lathe. When it slides above the machining area of ​​the lathe, the screw slide drives the second slider to descend until the clamped flange is aligned with the automatic chuck on the lathe. Then, the automatic chuck clamps the flange to facilitate machining. Then, the screw slide drives the second slider to slide vertically upward, thereby moving the two jaws out of the machining area to prevent affecting the flange machining.

[0019] After one end of the flange is machined, the second slide is driven down by the lead screw slide, which in turn drives the two jaws to re-enter the machining area and clamp the flange. After the automatic chuck on the machine tool releases, the second slide moves the two jaws and the clamped flange from the machining area to the top of the lathe. Then, the DC motor is started by the controller, which drives the first gear to rotate through its output end. Since the second gear is rotatably connected to the mounting plate through the second shaft, the first gear and the second gear mesh, which drives the adapter plate at the bottom of the second shaft to rotate 180 degrees. This, in turn, drives the flange between the two jaws to rotate 180 degrees through the mounting rod. The second slide is then driven down to the machining area by the lead screw slide and placed back onto the automatic chuck according to the above steps for machining the other end of the flange. After all the outer walls of the flange are machined, the flange is then drilled.

[0020] S4: Simultaneous processing of flange loading and pre-processing outer wall cleaning: As the sliding assembly moves the two grippers and the first flange on the right side of the base to slide closer to the lathe, the inner ring of the flange will abut against the wedge block. Under the contraction of the return spring, the wedge block follows the slide rod down, thereby causing the first slide plate to slide vertically down. Since the lifting rod is fixedly connected to one of the first slide plates, the first insert rod is fixedly connected to the lifting rod, the swing rod is rotatably connected to one of the limit plates, the first insert rod and the second insert rod are respectively inserted into two slots, and the baffle is fixedly connected to one end of the second insert rod, the rotation of the swing rod drives the second insert rod and the baffle to rise vertically from inside one of the covers, thereby opening the air supply pipe.

[0021] As the first slide plate slides vertically downwards, the swing arm drives the baffle plate to rise vertically, opening the air supply pipe. At the same time, the position sensor detects that the first slide plate has reached its maximum stroke, that is, the swing arm drives the baffle plate to rise to its maximum distance inside the cover, meaning the baffle plate no longer blocks the air supply pipe. This sends a signal to the controller, which then starts the blower. Since the air supply pipe is fixedly connected to the output end of the blower, several first branch pipes are designed at equal intervals at the end of the air supply pipe away from the blower. Each first U-shaped pipe is fixedly connected to one first branch pipe. Several high-pressure nozzles are fixedly connected to several first U-shaped pipes respectively. Every two high-pressure nozzles are fixedly connected to both ends of one first U-shaped pipe. High-pressure air is then sprayed out through several high-pressure nozzles. At the same time that the flange is removed from the material rack by the two grippers, the outer wall of the flange is simultaneously blown to clean the dust or metal debris on its outer wall.

[0022] S5: Simultaneous processing of flange blanking and post-processing external wall oiling: After flange drilling is completed, the processed flange is moved from the processing area to the material rack on the top left of the base via a material transfer mechanism. When the flange moves to the point where its inner ring abuts against the wedge block, due to the identical structure of the two trigger components and the two opening and closing components, another baffle is pulled out from the cover on the oil pipe, thus opening the oil pipe. Simultaneously, as the first slide plate slides vertically down, driving the baffle to rise vertically via the swing arm to open the oil pipe, the position sensor detects that the first slide plate has reached its maximum stroke, meaning the baffle has risen to its maximum distance inside the cover via the swing arm, thus no longer blocking the oil pipe. This sends a signal to the controller, which then controls the flow. The controller starts the oil pump, and the discharge pipe is fixedly connected to the bottom of the oil outlet. The discharge pipe and the oil supply pipe are fixedly connected to the input and output ends of the oil pump, respectively. Several second branch pipes are designed at equal intervals at the end of the oil supply pipe away from the oil pump. Each second U-shaped pipe is fixedly connected to a second branch pipe. Several atomizing nozzles are fixedly connected to several second U-shaped pipes. Every two atomizing nozzles are fixedly connected to both ends of a second U-shaped pipe. Then, rust-preventive oil is sprayed out through several atomizing nozzles. At the same time as the flange is moved from the lathe machining area to the material rack on the top left of the base by the material transfer mechanism, the outer wall of the machined flange is simultaneously sprayed with rust-preventive oil.

[0023] The beneficial effects of this invention are: This invention designs a material transfer mechanism, comprising a mounting frame, a sliding component, a rotating component, a driving component, and two grippers. It also incorporates two material racks: one for holding unfinished flange blanks awaiting processing, and the other for holding finished flanges. Through the coordinated operation of the sliding, rotating, and driving components, the unfinished flanges can be gripped from the racks and then transferred to the lathe machining area. The rotating component allows for the flipping of the unfinished flanges, enabling turning at both ends and overall drilling. After processing, the flanges are automatically placed back onto the other rack, achieving automated loading and unloading for flange lathe machining. The entire machining process, except for placing the unfinished flanges onto the racks, requires no manual intervention, reducing labor costs and minimizing worker contact with the lathe, thus reducing safety hazards during processing.

[0024] This invention, through the design of a jet assembly, a material rack, a trigger assembly, and an opening and closing assembly, allows for the simultaneous blowing of high-pressure air through several high-pressure nozzles during the loading of the flange onto the lathe machining area before machining, as the flange contacts one of the wedge blocks. This simultaneously blows air from the flange's outer wall, cleaning away dust and metal debris, preventing tilting or eccentricity during clamping, thus improving clamping accuracy, machining accuracy, and reducing scrap rate. It also protects the machining tool from chipping due to impacts from hard points on the flange surface, preventing slippage and accidental ejection of the flange during machining. Notably, the high-pressure nozzles are arranged in a circumferential array with equidistant installation, and the high-pressure nozzles at both ends of each first U-shaped tube are designed to be staggered at different heights. This allows for automatic blowing of the flange's circumferential and end faces as it is removed from the material rack, preventing any omissions and improving pre-machining cleaning efficiency.

[0025] This invention, through its design including an oil spraying assembly, a material rack, a triggering assembly, and an opening and closing assembly, allows for the spraying of rust-preventive oil through several atomizing nozzles during the process of placing the finished flange onto another material rack and contacting another wedge block. Simultaneously, as the flange is moved from the lathe machining area to the material rack on the top left of the base by the material transfer mechanism, the outer wall of the finished flange is sprayed with rust-preventive oil. This effectively blocks the intrusion of moisture and oxygen, achieving a rust-preventive effect, thus facilitating long-term storage or long-distance transportation. The oil collection box collects and collects any rust-preventive oil that drips during the spraying process, facilitating secondary use and reducing oiling costs.

[0026] This invention designs two position sensors and two triggering components. The oil pump or blower only starts when the position sensor detects that the first slide has slid down to its maximum stroke, that is, when the swing arm drives the baffle to rise to its maximum distance inside the cover, meaning that the baffle no longer blocks the oil or gas pipeline. Instead of being in a continuously open state, this invention can minimize the power consumption of the equipment and thus reduce the cost of cleaning and lubricating the flange.

[0027] This invention, by designing two trigger components, can automatically complete the pre-processing outer wall cleaning and post-processing outer wall oiling of flanges during the loading of blank flanges and the unloading of finished flanges, without the need for additional electric or manual drive, thereby improving the automation and functional integration of the equipment.

[0028] This invention designs an oil collection box that can collect and collect the rust-preventive oil that drips during the spraying process, facilitating its reuse and reducing oiling costs. Attached Figure Description

Detailed Implementation

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the invention. To better illustrate the embodiments of the invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions.

[0034] Reference Figures 1 to 15 As shown, the present invention provides a technical solution: an automatic loading and unloading conveying device for a lathe, including a base; It also includes a material transfer mechanism and a spraying mechanism; The material transfer mechanism is located on the top of the base. The material transfer mechanism includes a mounting frame 10, a sliding component, a rotating component, a driving component, and two grippers 11. Two pillars are fixedly provided on the top of the base. The mounting frame 10 is fixedly provided on the top of the two pillars. The sliding component is provided on the mounting frame 10. The rotating component is provided on the sliding component. The driving component is provided on the rotating component. The two grippers 11 are symmetrically arranged on the driving component. The spraying mechanism is located on the top of the base. The spraying mechanism includes a jetting component, an oil spraying component, two material racks 12, two triggering components, and two opening and closing components. The two material racks 12 are fixedly located at the top two ends of the base, and the two triggering components and the two opening and closing components are respectively located on the two material racks 12. The jetting component and the oil spraying component are respectively located on the two material racks 12.

[0035] Reference Figures 1 to 15 As shown, each material rack 12 includes a support plate 13, a movable support rod 14, and three fixed support rods 15. The support plate 13 is fixedly mounted on the top of the base. Several rubber blocks 16 are evenly spaced on the top of the support plate 13. The three fixed support rods 15 are evenly spaced on the top of the support plate 13. A sliding groove is provided on the support plate 13, and a first slider 17 is slidably mounted inside the groove. The movable support rod 14 is fixedly mounted on the first slider 17. An electric push rod 18 is fixedly mounted on the top of each support plate 13, and its output end is fixedly connected to the end of one of the first sliders 17 away from the movable support rod 14. This equipment is equipped with a controller, and all electrical devices on the equipment are electrically connected to the controller. When flange 63 needs to be processed, the controller first activates the electric push rod 18 on the material rack 12 on the top right of the base, causing its output end to extend upwards. This, in turn, drives the movable support rod 14 to slide upwards via the first slider 17. Then, flanges 63 are placed one by one between the movable support rod 14 and the three fixed support rods 15, ensuring that one end of the first flange 63 is in contact with several rubber stops 16, until the space between the movable support rod 14 and the three fixed support rods 15 is filled with flanges 63, indicating that flange 63 has been loaded. After completion, the controller retracts the output end of the electric push rod 18, thereby resetting the movable support rod 14 via the first slider 17. The movable support rod 14 and the three fixed support rods 15 provide support for the inner rings of all flanges 63. It should be noted that the above feeding operation is to prevent the flanges 63 from contacting the wedge block 19 and triggering it when manually feeding them onto the material rack 12, thus avoiding triggering the air jet assembly. After the anti-rust oil applied to the flanges 63 has solidified, the controller activates the electric push rod 18 on the left side of the material rack 12 at the top of the base, causing its output end to move upward. Extending out, another first slider 17 drives another movable support rod 14 to slide upward, thus facilitating the worker to grasp the flange 63 on the left side of the top of the base and simultaneously pull it away from the bearing plate during the upward lifting process until the oiled flange 63 is removed from the left side of the top of the base, realizing the unloading. It should be noted that the above material handling operation is to prevent the wedge block 19 on the material rack 12 from being triggered when unloading manually, thereby avoiding triggering the oil spraying component and preventing the anti-rust oil from spraying onto the worker's body and causing harm to the worker's skin or respiratory tract during material handling.

[0036] Reference Figures 1 to 15As shown, each triggering component includes a wedge block 19, a return spring 20, a slide rod 21, and a first sliding plate 22. Two limiting blocks 23 are fixedly provided at the ends of the two fixed support rods 15 away from the support plate 13. The slide rod 21 slides on one of the limiting blocks 23. The wedge block 19 and the first sliding plate 22 are fixedly provided at the top and bottom ends of the slide rod 21, respectively. The return spring 20 is sleeved on the outer wall of the slide rod 21. The wedge block 19 and the limiting block 23 abut against the two ends of the return spring 20, respectively. The sliding component drives the two grippers 11... As the first flange 63 on the right side of the top of the clamping base slides closer to the end near the lathe 64, the inner ring of the flange 63 will abut against the wedge block 19. Under the contraction of the return spring 20, the wedge block 19 follows the slide rod 21 down, thereby driving the first slide plate 22 to slide vertically down. Preferably, the material of the wedge block 19 can be selected as hard rubber, which can both abut against the flange 63 to complete the triggering operation and prevent scratches on the flange 63, thus preventing damage to the processed flange 63 and protecting the product.

[0037] Reference Figures 1 to 15 As shown, each opening and closing assembly includes a first insert rod 24, a second insert rod 25, a swing rod 26, a lifting rod 27, and a baffle 28. The lifting rod 27 is fixedly mounted on one of the first slide plates 22. The first insert rod 24 is fixedly mounted on the lifting rod 27. Two limiting plates are fixedly mounted at the bottom of the two movable support rods 14. The swing rod 26 is rotatably mounted on one of the limiting plates. Two slots are provided at both ends of the swing rod 26. The first insert rod 24 is inserted into one of the slots, and the second insert rod 25 is inserted into the other slot. The baffle 28 is fixedly mounted on one end of the second insert rod 25. Two position sensors 29 are fixedly mounted at the bottom of the two movable support rods 14. The detection surface of each position sensor 29 faces one of the first slide plates 22. When the first slide plate 22 slides down vertically, since the lifting rod 27 is fixedly connected to one of the first slide plates 22... The first insertion rod 24 is fixedly connected to the lifting rod 27, the swing rod 26 is rotatably connected to one of the limiting plates, the first insertion rod 24 and the second insertion rod 25 are respectively inserted into two slots, and the baffle 28 is fixedly connected to one end of the second insertion rod 25. Thus, the rotation of the swing rod 26 drives the second insertion rod 25 and the baffle 28 to rise vertically from inside one of the covers 42, thereby opening the air supply pipe 31.

[0038] Reference Figures 1 to 15As shown, the jet assembly includes a blower 30, an air supply pipe 31, several first branch pipes 32, several first U-shaped pipes 33, and several high-pressure nozzles 34. A support plate is fixedly mounted on the top of each support plate 13. The blower 30 is fixedly mounted on the top of one of the support plates. The air supply pipe 31 is fixedly mounted on its output end and passes through one of the support plates 13. Several first branch pipes 32 are evenly spaced at the end of the air supply pipe 31 furthest from the blower 30. Each first U-shaped pipe 33 is fixedly mounted on one of the first branch pipes 32. Several high-pressure nozzles 34 are respectively fixedly mounted on several first U-shaped pipes. On the 33, each pair of high-pressure nozzles 34 is fixedly connected to both ends of a first U-shaped tube 33. As the first slide plate 22 slides vertically down, the swing rod 26 drives the baffle 28 to rise vertically, opening the air supply pipe 31. Simultaneously, the position sensor 29 detects that the first slide plate 22 has reached its maximum stroke, meaning the swing rod 26 drives the baffle 28 to rise to its maximum distance inside the cover 42, thus the baffle no longer blocks the air supply pipe 31. This sends a signal to the controller, which then starts the blower 30. Since the air supply pipe 31 is fixedly connected to the output end of the blower 30, several first branch pipes 32 are designed at equal intervals on the air supply pipe 3... At the end furthest from the blower 30, each first U-shaped tube 33 is fixedly connected to a first branch tube 32. Several high-pressure nozzles 34 are fixedly connected to several first U-shaped tubes 33 respectively. Two high-pressure nozzles 34 are fixedly connected to both ends of each first U-shaped tube 33. High-pressure air is then ejected through these nozzles. Simultaneously, as the flange 63 is removed from the material rack 12 by the two grippers 11, the outer wall of the flange 63 is blown clean, removing dust or metal debris. This prevents the flange 63 from tilting or becoming eccentric during clamping, improving clamping accuracy and thus machining accuracy, while reducing... This reduces the scrap rate and prevents the cutting tool from chipping due to impacts from hard points on the surface of the flange 63, thus protecting the tool. It also prevents the flange 63 from slipping and flying off during processing, preventing safety accidents. It should be noted that the high-pressure nozzles 34 are arranged in a circumferential array and are installed at equal intervals. At the same time, the high-pressure nozzles 34 at both ends of each first U-tube 33 are designed to be parallel and staggered at different heights. This allows the flange 63 to be automatically purged on its circumferential surface and end face as it is removed from the material rack 12, thus avoiding any omissions and improving the cleaning efficiency of the flange 63 before processing.

[0039] Reference Figures 1 to 15As shown, the fuel injection assembly includes a fuel tank 35, a fuel pump 36, a discharge pipe 37, a fuel delivery pipe 38, several second branch pipes 39, several second U-shaped pipes 40, and several atomizing nozzles 41. The fuel tank 35 is fixedly mounted on the base, and the fuel pump 36 is fixedly mounted on the top of another support plate. The bottom of the fuel tank 35 has a discharge port, and the discharge pipe 37 is fixedly mounted at the bottom of the discharge port. The fuel delivery pipe 38 is inserted into another support plate 13. The discharge pipe 37 and the fuel delivery pipe 38 are fixedly connected to the input and output ends of the fuel pump 36, respectively. Several second branch pipes 39 are evenly spaced at the end of the fuel delivery pipe 38 away from the fuel pump 36. Each second U-shaped pipe 40 is fixedly mounted on a second branch pipe 39. Several atomizing nozzles 41... 1. Each of the two atomizing nozzles 41 is fixedly installed on several second U-shaped tubes 40. Each pair of atomizing nozzles 41 is fixedly connected to both ends of a second U-shaped tube 40. A cover 42 is fixedly installed on the outer wall of the oil supply pipe 38 and the air supply pipe 31. Each baffle 28 is inserted into a cover 42. Each cover 42 has a receiving groove for the baffle 28 to be inserted. An oil receiving box 43 is provided at one end of the top of the base. When the flange 63 is drilled, the processed flange 63 is moved from the processing area to the material rack 12 on the left side of the top of the base by the material transfer mechanism. When the flange 63 moves to the point where its inner ring abuts against the wedge block 19, due to the identical structure of the two trigger components and the two opening and closing components, another baffle 28 is driven from the oil supply pipe 38. The first slide plate 22 slides vertically down, driving the baffle 28 to rise vertically via the swing rod 26 to open the oil pipe 38. Simultaneously, the position sensor 29 detects that the first slide plate 22 has reached its maximum stroke, meaning the baffle 28 has risen to its maximum distance inside the cover 42 via the swing rod 26, thus no longer blocking the oil pipe 38. This sends a signal to the controller, which then starts the oil pump 36. The discharge pipe 37 is fixedly connected to the bottom of the discharge port. The discharge pipe 37 and the oil pipe 38 are fixedly connected to the input and output ends of the oil pump 36, respectively. Several second branch pipes 39 are equally spaced at the end of the oil pipe 38 furthest from the oil pump 36. Each second branch pipe... Each U-shaped tube 40 is fixedly connected to a second branch tube 39, and several atomizing nozzles 41 are fixedly connected to several second U-shaped tubes 40 respectively. Every two atomizing nozzles 41 are fixedly connected to both ends of a second U-shaped tube 40. Rust-preventive oil is sprayed through several atomizing nozzles 41. At the same time as the flange 63 is moved from the machining area of ​​the lathe 64 to the material rack 12 on the left side of the top of the base by the material transfer mechanism, the outer wall of the machined flange 63 is simultaneously sprayed with rust-preventive oil, thereby effectively blocking the intrusion of moisture and oxygen, achieving the effect of rust prevention, and facilitating long-term storage or long-distance transportation. The oil receiving box 43 can collect the rust-preventive oil that falls during the rust-preventive oil spraying process, which is convenient for secondary use and helps to reduce the oiling cost.

[0040] Reference Figures 1 to 15As shown, the sliding assembly includes a servo motor 44, an adapter frame 45, a second slide plate 46, a lead screw slide 47, a connecting block 48, a synchronous belt 49, and two synchronous pulleys 50. The servo motor 44 is fixedly mounted on the outer wall of the mounting frame 10. Each synchronous pulley 50 is rotatably mounted on one end of the mounting frame 10 via a first rotating shaft. The output end of the servo motor 44 is fixedly connected to the end of one of the first rotating shafts via a coupling. The synchronous belt 49 is sleeved between the two synchronous pulleys 50. The connecting block 48 is fixedly mounted on the outer wall of the synchronous belt 49. A guide rail is fixedly mounted on the outer wall of the mounting frame 10. The second slide plate 46 is slidably mounted on the guide rail. The lead screw slide 47 is fixedly mounted between the second slide plate 46 and the connecting block 48. A second slider 51 is slidably mounted on the lead screw slide 47. The adapter frame 45 is fixedly mounted on the outer wall of the mounting frame 10. On the second slider 51, after the movable support rod and three fixed support rods 15 on the right side of the top of the base provide support for the inner ring of all flanges 63, the servo motor 44 is started by the controller, so that its output end rotates. Since each synchronous wheel 50 is rotatably connected to one end of the mounting frame 10 through the first rotating shaft, the output end of the servo motor 44 is fixedly connected to the end of one of the first rotating shafts through the coupling. The two synchronous wheels 50 are sleeved by the synchronous belt 49. The connecting block 48 is fixedly connected to the synchronous belt 49. The second slide plate 46 is slidably connected to the guide rail. The second slide plate 46 and the connecting block 48 are both fixedly connected to the lead screw slide table 47. The second slider 51 is slidably mounted on the lead screw slide table 47, thereby driving the second slider 51 to slide towards the end of the right side of the top of the base 12.

[0041] Reference Figures 1 to 15As shown, the rotating assembly includes a DC motor 52, a first gear 53, a second gear 54, and a second rotating shaft 55. A mounting plate is fixedly installed at the bottom of the adapter frame 45. The DC motor 52 is inserted into the mounting plate, the first gear 53 is fixedly mounted on its output end, the second rotating shaft 55 is rotatably mounted on the mounting plate, and the second gear 54 is fixedly mounted on the second rotating shaft 55. The first gear 53 and the second gear 54 are meshed together. When one end of the flange 63 is finished, the second slider 51 is driven to descend via the lead screw slide 47, thereby causing the two grippers 11 to re-enter the machining area and clamp the flange 63. After the automatic chuck on the machine tool releases, the two grippers 11 and the clamped flange 63 are moved from the machining area to above the lathe 64 via the second slider 51. Then, the machine is started by the controller. A DC motor 52 drives the first gear 53 to rotate through its output end. Since the second gear 54 is rotatably connected to the mounting plate through the second rotating shaft 55, the first gear 53 and the second gear 54 mesh with each other, thereby driving the adapter plate 56 at the bottom of the second rotating shaft 55 to rotate 180 degrees. Then, through the mounting rod 57, the flange 63 between the two jaws 11 is rotated 180 degrees. Then, through the lead screw slide 47, the second slider 51 is driven to descend to the processing area and is placed back on the automatic chuck according to the above steps to perform turning processing on the other end of the flange 63. After all the outer walls of the flange 63 are turned, the flange 63 is then drilled. It should be noted that the lathe 64 used in conjunction with this equipment is a composite machining tool with multiple processing functions such as turning and drilling.

[0042] Reference Figures 1 to 15As shown, the drive assembly includes an adapter plate 56, a mounting rod 57, a stepper motor 58, a turntable 59, two connecting rods 60, two T-shaped sliders 61, and two centering plates 62. The adapter plate 56 is fixedly mounted on the bottom end of the second rotating shaft 55. The mounting rod 57 is fixedly mounted on the bottom of the adapter plate 56. The stepper motor 58 is inserted into the top of the mounting rod 57. The turntable 59 is fixedly mounted on its output end. The bottom of the mounting rod 57 has two symmetrically arranged T-shaped slots. Each T-shaped slider 61 is slidably mounted on one T-shaped slot. Each centering plate 62 is fixedly mounted on the other T-shaped slider. A T-shaped slider 61 is fixed at the bottom. Each connecting rod 60 is hinged between a turntable 59 and a centering plate 62. Each gripper 11 is fixedly connected to a centering plate 62. When the second slider 51 slides towards the end of the material rack 12 on the top right of the base until the two grippers 11 are aligned with the first flange 63 on the material rack 12 on the top right of the base, the servo motor 44 is first powered off by the controller, so that the two grippers 11 stop sliding. Then, the stepper motor 58 is started by the controller, so that its output end drives the turntable. Option 59: Since the adapter plate 56 is fixedly connected to the bottom end of the second rotating shaft 55, the mounting rod 57 is fixedly connected to the bottom of the adapter plate 56, each T-shaped slide bar 61 is slidably connected to a T-slot, each centering plate 62 is fixedly connected to the bottom of a T-shaped slide bar 61, the turntable 59 and a centering plate 62 are respectively hinged to both ends of a connecting rod 60, and each gripper 11 is fixedly connected to a centering plate 62, thereby driving the two grippers 11 to move closer to each other and clamp the first flange 63 located on the leftmost side of the material rack 12. The sliding assembly drives the two grippers 11 and the first flange 63 to slide towards the end of the lathe 64. When it slides above the machining area of ​​the lathe 64, the lead screw slide 47 drives the second slider 51 to descend until the clamped flange 63 is aligned with the automatic chuck on the lathe 64. Then the automatic chuck clamps the flange 63 to facilitate machining. Then the lead screw slide 47 drives the second slider 51 to slide vertically upward, thereby moving the two grippers 11 out of the machining area to prevent affecting the machining of the flange 63.

[0043] A method of using an automatic loading and unloading conveyor for a lathe includes the following steps: S1: Flange loading: This equipment is equipped with a controller, and all electrical devices on the equipment are electrically connected to the controller. When flange 63 needs to be processed, the controller first activates the electric push rod 18 on the material rack 12 on the top right of the base, so that its output end extends upward. This causes the movable support rod 14 to slide upward through the first slider 17. Then, flanges 63 are placed one by one between the movable support rod 14 and the three fixed support rods 15, keeping one end of the first flange 63 in contact with several rubber blocks 16, until the space between the movable support rod 14 and the three fixed support rods 15 is full of flanges 63. This indicates that the flanges 63 have been fed. Then, the controller drives the output end of the electric push rod 18 to retract, which causes the movable support rod 14 to reset through the first slider 17. The movable support rod 14 and the three fixed support rods 15 provide support for the inner ring of all flanges 63.

[0044] S2: Flange cutting: After the anti-rust oil applied to flange 63 has solidified, the electric push rod 18 on the left side of the top of the base is activated by the controller, so that its output end extends upward. Through another first slider 17, another movable support rod 14 slides upward, making it easier for the worker to grasp the flange 63 on the left side of the top of the base and pull it away from the bearing plate in the process of lifting it up, until the oiled flange 63 is removed from the left side of the top of the base, thus realizing the unloading.

[0045] S3: Flange clamping, turning, and drilling: After the movable support rod and three fixed support rods 15 on the right side of the top of the base provide support for the inner ring of all flanges 63, the servo motor 44 is started by the controller, so that its output end rotates. Since each synchronous wheel 50 is rotatably connected to one end of the mounting frame 10 through the first rotating shaft, the output end of the servo motor 44 is fixedly connected to the end of one of the first rotating shafts through the coupling. The two synchronous wheels 50 are sleeved by the synchronous belt 49. The connecting block 48 is fixedly connected to the synchronous belt 49. The second slide plate 46 is slidably connected to the guide rail. The second slide plate 46 and the connecting block 48 are both fixedly connected to the lead screw slide table 47. The second slider 51 is slidably provided on the lead screw slide table 47, thereby driving the second slider 51 to slide towards one end of the material rack 12 on the right side of the top of the base.

[0046] When the second slider 51 slides towards the end of the material rack 12 on the right side of the top of the base until the two grippers 11 are aligned with the first flange 63 on the material rack 12 on the right side of the top of the base, the servo motor 44 is first powered off by the controller, so that the two grippers 11 stop sliding. Then, the stepper motor 58 is started by the controller, so that its output end drives the turntable 59. Since the adapter plate 56 is fixedly connected to the bottom end of the second rotating shaft 55, the mounting rod 57 is fixedly connected to the bottom of the adapter plate 56, each T-shaped slide bar 61 is slidably connected to a T-shaped groove, and each centering plate 62 is fixedly connected to the bottom of a T-shaped slide bar 61. The turntable 59 and the centering plate 62 are respectively hinged to the two ends of a connecting rod 60. Each of the grippers 11 is fixedly connected to a centering plate 62, thereby driving the two grippers 11 to move closer to each other and clamp the first flange 63 located on the leftmost side of the material rack 12. Then, the two grippers 11 and the clamped first flange 63 are driven to slide towards the end of the lathe 64 through the sliding assembly. When they slide above the machining area of ​​the lathe 64, the second slider 51 is driven to descend through the lead screw slide 47 until the clamped flange 63 is aligned with the automatic chuck on the lathe 64. Then, the automatic chuck clamps the flange 63 to facilitate machining. Then, the second slider 51 is driven to slide vertically upward through the lead screw slide 47, thereby moving the two grippers 11 out of the machining area to prevent affecting the machining of the flange 63.

[0047] After one end of flange 63 is machined, the second slider 51 is driven down by the lead screw slide 47, which causes the two jaws 11 to re-enter the machining area and clamp flange 63. After the automatic chuck on the machine tool is released, the second slider 51 drives the two jaws 11 and the clamped flange 63 to move out of the machining area and onto the lathe 64. Then, the DC motor 52 is started by the controller, which drives the first gear 53 to rotate through its output end. Since the second gear 54 is rotatably connected to the mounting plate through the second shaft 55, the first gear 53 and the second gear 54 are meshed, which drives the adapter plate 56 at the bottom of the second shaft 55 to rotate 180 degrees. Then, the mounting rod 57 drives the flange 63 between the two jaws 11 to rotate 180 degrees. The second slider 51 is then driven down to the machining area by the lead screw slide 47 and placed back onto the automatic chuck according to the above steps to machine the other end of flange 63. After all the outer walls of flange 63 are machined, the flange 63 is then drilled.

[0048] S4: Simultaneous processing of flange loading and pre-processing outer wall cleaning: As the sliding assembly drives the two grippers 11 and the first flange 63 on the right side of the base 12 to slide closer to the lathe 64, the inner ring of the flange 63 will abut against the wedge block 19. Under the contraction of the return spring 20, the wedge block 19 follows the slide rod 21 down, thereby driving the first slide plate 22 to slide vertically down. Since the lifting rod 27 is fixedly connected to one of the first slide plates 22, the first insertion rod 24 is fixedly connected to the lifting rod 27, the swing rod 26 is rotatably connected to one of the limiting plates, the first insertion rod 24 and the second insertion rod 25 are respectively inserted into the two slots, and the baffle 28 is fixedly connected to one end of the second insertion rod 25, the rotation of the swing rod 26 drives the second insertion rod 25 and the baffle 28 to rise vertically from inside one of the covers 42, thereby opening the air supply pipe 31.

[0049] As the first slide plate 22 slides vertically downwards, the lever 26 drives the baffle 28 to rise vertically, opening the air supply pipe 31. Simultaneously, the position sensor 29 detects that the first slide plate 22 has reached its maximum stroke, meaning the lever 26 drives the baffle 28 to rise to its maximum distance inside the housing 42, thus removing the baffle from blocking the air supply pipe 31. This sends a signal to the controller, which then starts the blower 30. Since the air supply pipe 31 is fixedly connected to the output end of the blower 30, several first branch pipes 32 are designed at equal intervals... At the end of the air supply pipe 31 away from the blower 30, each first U-shaped pipe 33 is fixedly connected to a first branch pipe 32, and several high-pressure nozzles 34 are fixedly connected to several first U-shaped pipes 33 respectively. Every two high-pressure nozzles 34 are fixedly connected to both ends of a first U-shaped pipe 33 respectively, so that high-pressure air is sprayed out through several high-pressure nozzles 34. At the same time as the flange 63 is removed from the material rack 12 by the two grippers 11, the outer wall of the flange 63 is simultaneously blown to clean the dust or metal debris on its outer wall.

[0050] S5: Simultaneous processing of flange blanking and post-processing external wall oiling: After drilling of flange 63 is completed, the processed flange 63 is moved from the processing area to the material rack 12 on the top left of the base by the material transfer mechanism. When the flange 63 moves to the point where its inner ring abuts against the wedge block 19, due to the identical structure of the two trigger components and the two opening and closing components, another baffle 28 is pulled out from the cover 42 on the oil pipe 38, thus opening the oil pipe 38. At the same time as the first slide plate 22 slides down vertically and drives the baffle 28 to rise vertically through the swing rod 26 to open the oil pipe 38, the position sensor 29 detects that the first slide plate 22 has slid down to its maximum stroke, that is, the baffle 28 is driven to rise to its maximum distance inside the cover 42 through the swing rod 26, meaning that the baffle no longer blocks the oil pipe 38, thereby sending a signal to the controller, and then controlling the... The controller starts the oil pump 36, and the discharge pipe 37 is fixedly connected to the bottom of the oil outlet. The discharge pipe 37 and the oil supply pipe 38 are fixedly connected to the input end and output end of the oil pump 36, respectively. Several second branch pipes 39 are designed at equal intervals at the end of the oil supply pipe 38 away from the oil pump 36. Each second U-shaped pipe 40 is fixedly connected to a second branch pipe 39. Several atomizing nozzles 41 are fixedly connected to several second U-shaped pipes 40. Every two atomizing nozzles 41 are fixedly connected to both ends of a second U-shaped pipe 40, and then the anti-rust oil is sprayed out through several atomizing nozzles 41. At the same time as the flange 63 is moved from the machining area of ​​the lathe 64 to the material rack 12 on the top left of the base by the material transfer mechanism, the outer wall of the machined flange 63 is simultaneously sprayed with anti-rust oil.

[0051] The working principle of this invention is as follows: This equipment is equipped with a controller, and all electrical devices on the equipment are electrically connected to the controller. When flange 63 needs to be processed, the controller first activates the electric push rod 18 on the material rack 12 on the top right of the base, so that its output end extends upward. This causes the movable support rod 14 to slide upward through the first slider 17. Then, flanges 63 are placed one by one between the movable support rod 14 and the three fixed support rods 15, and one end of the first flange 63 is kept in contact with several rubber blocks 16 until the space between the movable support rod 14 and the three fixed support rods 15 is full of flanges 63. This indicates that the flanges 63 have been fed. Then, the controller drives the output end of the electric push rod 18 to retract, which causes the movable support rod 14 to reset through the first slider 17. The movable support rod 14 and the three fixed support rods 15 provide support for the inner ring of all flanges 63.

[0052] After the movable support rod and three fixed support rods 15 on the right side of the top of the base provide support for the inner ring of all flanges 63, the servo motor 44 is started by the controller, so that its output end rotates. Since each synchronous wheel 50 is rotatably connected to one end of the mounting frame 10 through the first rotating shaft, the output end of the servo motor 44 is fixedly connected to the end of one of the first rotating shafts through the coupling. The two synchronous wheels 50 are sleeved by the synchronous belt 49. The connecting block 48 is fixedly connected to the synchronous belt 49. The second slide plate 46 is slidably connected to the guide rail. The second slide plate 46 and the connecting block 48 are both fixedly connected to the lead screw slide table 47. The second slider 51 is slidably provided on the lead screw slide table 47, thereby driving the second slider 51 to slide towards one end of the material rack 12 on the right side of the top of the base.

[0053] When the second slider 51 slides towards the end of the material rack 12 on the right side of the top of the base until the two grippers 11 are aligned with the first flange 63 on the material rack 12 on the right side of the top of the base, the servo motor 44 is first powered off by the controller, so that the two grippers 11 stop sliding. Then, the stepper motor 58 is started by the controller, so that its output end drives the turntable 59. Since the adapter plate 56 is fixedly connected to the bottom end of the second rotating shaft 55, the mounting rod 57 is fixedly connected to the bottom of the adapter plate 56, each T-shaped slide bar 61 is slidably connected to a T-shaped groove, and each centering plate 62 is fixedly connected to the bottom of a T-shaped slide bar 61. The turntable 59 and the centering plate 62 are respectively hinged to the two ends of a connecting rod 60. Each of the grippers 11 is fixedly connected to a centering plate 62, thereby driving the two grippers 11 to move closer to each other and clamp the first flange 63 located on the leftmost side of the material rack 12. Then, the two grippers 11 and the clamped first flange 63 are driven to slide towards the end of the lathe 64 through the sliding assembly. When they slide above the machining area of ​​the lathe 64, the second slider 51 is driven to descend through the lead screw slide 47 until the clamped flange 63 is aligned with the automatic chuck on the lathe 64. Then, the automatic chuck clamps the flange 63 to facilitate machining. Then, the second slider 51 is driven to slide vertically upward through the lead screw slide 47, thereby moving the two grippers 11 out of the machining area to prevent affecting the machining of the flange 63.

[0054] After one end of flange 63 is machined, the second slider 51 is driven down by the lead screw slide 47, which causes the two jaws 11 to re-enter the machining area and clamp flange 63. After the automatic chuck on the machine tool is released, the second slider 51 drives the two jaws 11 and the clamped flange 63 to move out of the machining area and onto the lathe 64. Then, the DC motor 52 is started by the controller, which drives the first gear 53 to rotate through its output end. Since the second gear 54 is rotatably connected to the mounting plate through the second shaft 55, the first gear 53 and the second gear 54 are meshed, which drives the adapter plate 56 at the bottom of the second shaft 55 to rotate 180 degrees. Then, the mounting rod 57 drives the flange 63 between the two jaws 11 to rotate 180 degrees. The second slider 51 is then driven down to the machining area by the lead screw slide 47 and placed back onto the automatic chuck according to the above steps to machine the other end of flange 63. After all the outer walls of flange 63 are machined, the flange 63 is then drilled.

[0055] After the anti-rust oil applied to flange 63 has solidified, the electric push rod 18 on the left side of the top of the base is activated by the controller, so that its output end extends upward. Through another first slider 17, another movable support rod 14 slides upward, making it easier for the worker to grasp the flange 63 on the left side of the top of the base and pull it away from the bearing plate in the process of lifting it up, until the oiled flange 63 is removed from the left side of the top of the base, thus realizing the unloading.

[0056] As the sliding assembly drives the two grippers 11 and the first flange 63 on the right side of the base 12 to slide closer to the lathe 64, the inner ring of the flange 63 will abut against the wedge block 19. Under the contraction of the return spring 20, the wedge block 19 follows the slide rod 21 down, thereby driving the first slide plate 22 to slide vertically down. Since the lifting rod 27 is fixedly connected to one of the first slide plates 22, the first insertion rod 24 is fixedly connected to the lifting rod 27, the swing rod 26 is rotatably connected to one of the limiting plates, the first insertion rod 24 and the second insertion rod 25 are respectively inserted into the two slots, and the baffle 28 is fixedly connected to one end of the second insertion rod 25, the rotation of the swing rod 26 drives the second insertion rod 25 and the baffle 28 to rise vertically from inside one of the covers 42, thereby opening the air supply pipe 31.

[0057] As the first slide plate 22 slides vertically downwards, the lever 26 drives the baffle 28 to rise vertically, opening the air supply pipe 31. Simultaneously, the position sensor 29 detects that the first slide plate 22 has reached its maximum stroke, meaning the lever 26 drives the baffle 28 to rise to its maximum distance inside the housing 42, thus removing the baffle from blocking the air supply pipe 31. This sends a signal to the controller, which then starts the blower 30. Since the air supply pipe 31 is fixedly connected to the output end of the blower 30, several first branch pipes 32 are designed at equal intervals... At the end of the air supply pipe 31 away from the blower 30, each first U-shaped pipe 33 is fixedly connected to a first branch pipe 32, and several high-pressure nozzles 34 are fixedly connected to several first U-shaped pipes 33 respectively. Every two high-pressure nozzles 34 are fixedly connected to both ends of a first U-shaped pipe 33 respectively, so that high-pressure air is sprayed out through several high-pressure nozzles 34. At the same time as the flange 63 is removed from the material rack 12 by the two grippers 11, the outer wall of the flange 63 is simultaneously blown to clean the dust or metal debris on its outer wall.

[0058] After drilling of flange 63 is completed, the processed flange 63 is moved from the processing area to the material rack 12 on the top left of the base by the material transfer mechanism. When the flange 63 moves to the point where its inner ring abuts against the wedge block 19, due to the identical structure of the two trigger components and the two opening and closing components, another baffle 28 is pulled out from the cover 42 on the oil pipe 38, thus opening the oil pipe 38. At the same time as the first slide plate 22 slides down vertically and drives the baffle 28 to rise vertically through the swing rod 26 to open the oil pipe 38, the position sensor 29 detects that the first slide plate 22 has slid down to its maximum stroke, that is, the baffle 28 is driven to rise to its maximum distance inside the cover 42 through the swing rod 26, meaning that the baffle no longer blocks the oil pipe 38, thus sending a signal to the controller, which in turn starts the oil pump 36, discharging the bottom of the discharge pipe 37 and the discharge port. The discharge pipe 37 and the oil supply pipe 38 are fixedly connected to the input and output ends of the oil pump 36, respectively. Several second branch pipes 39 are designed at equal intervals at the end of the oil supply pipe 38 away from the oil pump 36. Each second U-shaped pipe 40 is fixedly connected to a second branch pipe 39. Several atomizing nozzles 41 are fixedly connected to several second U-shaped pipes 40. Every two atomizing nozzles 41 are fixedly connected to both ends of a second U-shaped pipe 40. Rust-preventive oil is sprayed out through several atomizing nozzles 41. At the same time as the flange 63 is moved from the machining area of ​​the lathe 64 to the material rack 12 on the top left of the base by the material transfer mechanism, the outer wall of the machined flange 63 is simultaneously sprayed with rust-preventive oil. The oil receiving box 43 can collect and collect the rust-preventive oil that falls during the rust-preventive oil spraying process, which is convenient for secondary use and helps to reduce the oiling cost.

10. A method of using an automatic loading and unloading conveyor for a lathe according to any one of claims 1-9, comprising the following steps: S1: Flange loading: This equipment is equipped with a controller. All electrical devices on the equipment are electrically connected to the controller. When a flange needs to be processed, the electric push rod (18) on the right side of the material rack (12) at the top of the base is activated by the controller, so that its output end extends upward. Then, the movable support rod (14) is driven upward by the first slider (17). The flanges are then placed one by one between the movable support rod (14) and the three fixed support rods (15), and one end of the first flange is kept in contact with several rubber blocks (16) until the flanges are fully placed between the movable support rod (14) and the three fixed support rods (15). This indicates that the flange loading is complete. Then, the output end of the electric push rod (18) is retracted by the controller, so that the movable support rod (14) is reset by the first slider (17). The movable support rod (14) and the three fixed support rods (15) provide support for the inner ring of all flanges. S2: Flange cutting: After the anti-rust oil applied to the flange has solidified, the electric push rod (18) on the left side of the top of the base (12) is activated by the controller, so that its output end extends upward. Through another first slider (17), another movable support rod (14) slides upward, so that the worker can easily grasp the flange on the left side of the top of the base (12) and pull it away from the bearing plate in the process of lifting it upward until the oiled flange is removed from the left side of the top of the base (12) and the material is unloaded. S3: Flange clamping, turning, and drilling: After the movable support rod and three fixed support rods (15) on the right side of the top of the base provide support for the inner ring of all flanges, the servo motor (44) is started by the controller, so that its output end rotates. Since each synchronous wheel (50) is rotatably connected to one end of the mounting frame (10) through the first rotating shaft, the output end of the servo motor (44) is fixedly connected to the end of one of the first rotating shafts through the coupling. The two synchronous wheels (50) are sleeved through the synchronous belt (49). The connecting block (48) is fixedly connected to the synchronous belt (49). The second slide plate (46) is slidably connected to the guide rail. The second slide plate (46) and the connecting block (48) are both fixedly connected to the screw slide table (47). The second slider (51) is slidably provided on the screw slide table (47), so that the second slider (51) is driven to slide towards the end of the right side of the top of the base (12). When the second slider (51) slides towards the end of the material rack (12) on the right side of the top of the base until the two grippers (11) are aligned with the first flange on the material rack (12) on the right side of the top of the base, the servo motor (44) is first powered off by the controller, so that the two grippers (11) stop sliding. Then the stepper motor (58) is started by the controller, so that its output end drives the turntable (59) to select. Since the adapter plate (56) is fixedly connected to the bottom of the second rotating shaft (55), the mounting rod (57) is fixedly connected to the bottom of the adapter plate (56), each T-shaped slide bar (61) is slidably connected to a T-shaped groove, and each centering plate (62) is fixedly connected to the bottom of a T-shaped slide bar (61). The turntable (59) and a centering plate (62) are respectively connected to a T-shaped groove. The two ends of the connecting rod (60) are hinged, and each gripper (11) is fixedly connected to a centering plate (62), thereby driving the two grippers (11) to move closer to each other and clamp the first flange on the leftmost side of the material rack (12). Then, the two grippers (11) and the clamped first flange are driven to slide towards the end of the lathe through the sliding assembly. When they slide above the lathe processing area, the second slider (51) is driven down through the screw slide (47) until the clamped flange is aligned with the automatic chuck on the lathe. Then, the flange is clamped by the automatic chuck, which facilitates processing. Then, the second slider (51) is driven to slide vertically upward through the screw slide (47), thereby driving the two grippers (11) to move out of the processing area to prevent affecting the flange processing. After one end of the flange is machined, the second slide (51) is driven down by the lead screw slide (47), thereby driving the two jaws (11) to re-enter the machining area and clamp the flange. After the automatic chuck on the machine tool is released, the two jaws (11) and the clamped flange are moved from the machining area to the top of the lathe by the second slide (51). Then, the DC motor (52) is started by the controller, thereby driving the first gear (53) to rotate through its output end. Since the second gear (54) is connected to the flange by the second rotating shaft (55), the second slide (54) is driven down by the second rotating shaft (55). The mounting plate is rotated and connected, and the first gear (53) and the second gear (54) mesh and connect, thereby driving the adapter plate (56) at the bottom of the second rotating shaft (55) to rotate 180 degrees. Then, the mounting rod (57) drives the flange between the two jaws (11) to rotate 180 degrees. Then, the screw slide (47) drives the second slider (51) to descend to the processing area and put it back on the automatic chuck according to the above steps to perform turning processing on the other end of the flange. After all the outer walls of the flange are turned, the flange is drilled. S4: Simultaneous processing of flange loading and pre-processing outer wall cleaning: As the sliding assembly drives the two grippers (11) and the first flange on the right side of the base (12) to slide closer to the lathe, the inner ring of the flange will abut against the wedge block (19). Under the contraction of the return spring (20), the wedge block (19) slides down with the slide bar (21), thereby driving the first slide plate (22) to slide down vertically. Since the lifting rod (27) is fixedly connected to one of the first slide plates (22), the first insert rod (24) is fixedly connected to the lifting rod (27), the swing rod (26) is rotatably connected to one of the limit plates, the first insert rod (24) and the second insert rod (25) are respectively inserted into the two slots, and the baffle (28) is fixedly connected to one end of the second insert rod (25). Thus, the rotation of the swing rod (26) drives the second insert rod (25) and the baffle (28) to rise vertically from inside one of the covers (42), thereby realizing the opening of the air pipe (31). As the first slide plate (22) slides vertically down, the lever (26) drives the baffle (28) to rise vertically, opening the air supply pipe (31). At the same time, the position sensor (29) detects that the first slide plate (22) has slid down to its maximum stroke, that is, the lever (26) drives the baffle (28) to rise to its maximum distance inside the cover (42), meaning the baffle no longer blocks the air supply pipe (31), thus sending a signal to the controller, which in turn starts the blower (30). Since the air supply pipe (31) is fixedly connected to the output end of the blower (30), several first branch pipes (32), etc. The spacing is designed at the end of the gas pipe (31) away from the blower (30). Each first U-shaped pipe (33) is fixedly connected to a first branch pipe (32). Several high-pressure nozzles (34) are fixedly connected to several first U-shaped pipes (33). Every two high-pressure nozzles (34) are fixedly connected to the two ends of a first U-shaped pipe (33). High-pressure air is sprayed out through several high-pressure nozzles (34). At the same time as the flange is removed from the material rack (12) by the two grippers (11), the outer wall of the flange is blown to clean the dust or metal debris on its outer wall. S5: Simultaneous processing of flange blanking and post-processing external wall oiling: After the flange drilling is completed, the processed flange is transferred from the processing area to the material rack (12) on the left side of the top of the base by the material transfer mechanism. When the flange moves to the point where its inner ring abuts against the wedge block (19), due to the consistent structure of the two trigger components and the two opening and closing components, another baffle (28) is pulled out from the cover (42) on the oil pipe (38), thus opening the oil pipe (38). At the same time as the first slide plate (22) slides down vertically and drives the baffle (28) to rise vertically through the swing rod (26) to open the oil pipe (38), the position sensor (29) detects that the first slide plate (22) has slid down to the maximum stroke, that is, the baffle (28) is driven to rise to the maximum distance inside the cover (42) through the swing rod (26), that is, the baffle no longer blocks the gas pipe (31), thus sending a signal to the controller, and then controlling the controller. The controller starts the oil pump (36), the discharge pipe (37) is fixedly connected to the bottom of the oil outlet, the discharge pipe (37) and the oil supply pipe (38) are fixedly connected to the input end and the output end of the oil pump (36) respectively, several second branch pipes (39) are designed at equal intervals at the end of the oil supply pipe (38) away from the oil pump (36), each second U-shaped pipe (40) is fixedly connected to a second branch pipe (39), several atomizing nozzles (41) are fixedly connected to several second U-shaped pipes (40) respectively, and every two atomizing nozzles (41) are fixedly connected to the two ends of a second U-shaped pipe (40) respectively, and then the anti-rust oil is sprayed out through several atomizing nozzles (41). While the flange is moved from the lathe processing area to the material rack (12) on the left side of the top of the base by the material transfer mechanism, the outer wall of the processed flange is sprayed with anti-rust oil at the same time.
