[0016] Compared with related technologies, the heavy-duty horizontal lathe drilling and milling integrated machining device provided by the present invention has the following beneficial effects: This invention provides a heavy-duty horizontal lathe drilling and milling integrated machining device. Through the cooperation of lifting components, locking components, clamping components, and internal components, the device uses a motor-driven gear meshing to drive the screw to rotate. The relative sliding of two moving plates is achieved by the opposing threads, which can smoothly lift and lower the lifting base. Through the cooperation of the locking shaft, locking plate, third spring, and unlocking plate, the material bin and the lifting base can be automatically locked and unlocked. When the material bin slides in, the locking shaft is squeezed and contracted. After it is in place, it automatically pops out and locks, effectively preventing displacement and shaking during lifting. When it is raised to the top, the unlocking plate squeezes the locking shaft to automatically unlock, thus eliminating the need for manual operation and improving the degree of automation. Driven by a hydraulic cylinder and guided by the second roller, the device can guide shaft parts to automatically center. The subsequent pressure plate clamps the part by squeezing the clamping seat through the inclined surface and is fixed with an electromagnetic pin to ensure that the part is firmly clamped. It is suitable for parts of different diameters. By cooperating with the moving mechanism and internal components, the material hopper can be smoothly transferred, providing convenience for clamping and processing shaft parts. Multiple second cylinders can drive the moving frame to slide up and down, precisely adjust the height of the material hopper, and ensure that the circular openings on both sides of the material hopper are aligned with the center of the lathe chuck. The first motor drives the rotating shaft to rotate, and through the transmission of sprockets and chain belts, all rollers rotate synchronously, thereby realizing the smooth movement of the material hopper along the axial direction. This reduces the labor intensity of operators and avoids the problems of part collisions, positional shifts, and frequent use and scheduling of auxiliary tools such as cranes and forklifts caused by manual transfer. Through the cooperation of the lubrication assembly and its internal components, the lubrication assembly is linked with the lifting base. When the lifting base rises, the trapezoidal stop block moves upward. Since the trapezoidal stop block can only rotate upward, its sixth inclined surface will precisely contact and press against the fifth inclined surface of the trapezoidal pressure block. The rectangular pressing plate presses the airbag, and after the airbag is compressed, the internal air is injected into the filling seat through the air pipe, thereby pressurizing the lubricating medium in the storage box chamber. It is then precisely delivered to the lubrication part in the transport frame through the oil drain pipe, realizing the synchronous action of lubrication upon lifting. This ensures the lubrication needs of the sliding parts during the lifting process. When the lifting base descends, the trapezoidal stop block cannot rotate downward due to structural limitations and has no pressing contact with the trapezoidal pressure block. It will not drive the airbag to move, avoiding the ineffective consumption of the lubricating medium and realizing lubrication on demand. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] First embodiment: Please refer to the following: Figures 1-12 In the first embodiment of the present invention, the heavy-duty horizontal lathe drilling and milling integrated machining device includes: a base plate 2 and two transport frames 8 disposed at the bottom of the lathe 1. The base plate 2 is slidably installed on the bottom inner wall of the lathe 1. The two transport frames 8 are respectively fixedly installed at both ends of the base plate 2. A material bin 6 is slidably installed in one of the transport frames 8. The material bin 6 has circular openings on both sides. A clamping assembly is disposed in the material bin 6. The clamping assembly is used to clamp shaft parts. A lifting mechanism is disposed on the top of the base plate 2 and in the two transport frames 8. The lifting mechanism includes a lifting assembly and two sets of locking assemblies. The lifting assembly is used to lift and lower the material bin 6 in the transport frame 8. The locking assembly is used to fix the material bin 6 in the lifting base 3. The two transport frames 8 are provided with the same moving mechanism 9. The moving mechanism 9 is used to move the material bin 6 to a designated position, and the moving mechanism 9 is located above the lathe 1.

[0021] The lifting assembly includes two lifting bases 3, a first screw 16, two moving plates 14, and a second motor 17. The two lifting bases 3 are slidably installed in two transport frames 8, and the hopper 6 is set in the two lifting bases 3. The first screw 16 is rotatably installed on the top of the base plate 2. The two moving plates 14 are slidably installed on the top of the base plate 2, and both moving plates 14 are threadedly connected to the first screw 16. One end of the lifting rod 15 is rotatably installed on the top of each of the two moving plates 14, and the other end of the two lifting rods 15 is rotatably installed on the side of the two lifting bases 3 that are close to each other. The second motor 17 is fixedly installed on the top of the base plate 2. A first gear 18 is fixedly installed on the output shaft of the second motor 17, and a second gear 20 is fixedly installed on the outer wall of the first screw 16. The second gear 20 meshes with the first gear 18. When the first screw 16 rotates, since the two moving plates 14 are threadedly connected to the first screw 16 and the threads are opposite, the two moving plates 14 will slide in a direction away from each other. The lifting rod 15 drives the lifting base 3 to slowly rise in the transport frame 8.

[0022] Each locking assembly includes two locking plates 13, two limiting seats 11, two locking shafts 12, and two unlocking plates 19. The two unlocking plates 19 are fixedly installed on the top inner wall of the transport frame 8, and each unlocking plate 19 has a first inclined surface at its bottom. The two limiting seats 11 are fixedly installed on the top of the hopper 6. The two locking plates 13 are fixedly installed on the top of the lifting base 3, and each locking plate 13 has a guide groove on its opposite side. Each guide groove has a second inclined surface at its bottom, and each guide groove has a locking hole on its side near the limiting seat 11. The two locking shafts 12 are slidably installed in the two limiting seats 11, and the ends of the two locking shafts 12 near the locking plates 13 pass through the two locking holes and extend to the two locking plates 13. Inside the guide groove, one end of a third spring 30 is fixedly installed at one end of each of the two clamping shafts 12 that are close to each other. The other ends of the two third springs 30 are fixedly connected to the two limiting seats 11 respectively. During the sliding process of the hopper 6 in the lifting base 3, the end of the clamping shaft 12 in the limiting seat 11 first contacts the clamping plate 13 at the top of the lifting base 3. Under the pressure of the clamping plate 13, the clamping shaft 12 retracts into the limiting seat 11, and at the same time compresses the third spring 30. When the hopper 6 falls completely into the lifting base 3 and fits in place, the clamping shaft 12 aligns with the clamping hole on the clamping plate 13, the third spring 30 resets, pushes the clamping shaft 12 through the clamping hole and extends into the guide groove, and the hopper 6 is locked in the lifting base 3 to prevent the hopper 6 from shifting when the lifting base 3 rises.

[0023] The clamping assembly includes two hydraulic cylinders 5, two pressure plates 4, a movable frame 21, and two clamping seats 24. The two hydraulic cylinders 5 are fixedly installed on the top inner wall of the hopper 6. The movable frame 21 is slidably installed inside the hopper 6. Multiple guide limit bolts 22 are fixedly installed on the top of the movable frame 21. The two pressure plates 4 are slidably installed on the multiple guide limit bolts 22. The telescopic ends of the hydraulic cylinders 5 are fixedly connected to the pressure plates 4. A first spring 23 is sleeved on the outer side of each of the multiple guide limit bolts 22. The two ends of the first spring 23 are fixedly connected to the pressure plates 4 and the movable frame 21, respectively. The two clamping seats 24 are slidably installed inside the movable frame 21, and a second roller 27 is rotatably installed on the side of each clamping seat 24 that is close to each other. The inner wall of 21 is provided with multiple sliding grooves, and guide rods 28 are fixedly installed in each of the multiple sliding grooves. Fixing ears are slidably installed on the outer walls of the multiple guide rods 28, and the fixing ears are respectively fixedly installed on the outer walls of the two clamps 24. Second springs 25 are sleeved on the outer walls of the multiple guide rods 28, and the two ends of the second springs 25 are respectively fixedly connected to the fixing ears and the sliding grooves. The top of each of the two clamps 24 is provided with a groove, and the bottom of the groove is provided with a third inclined surface. Both sides of the two grooves are provided with mounting grooves, and electromagnetic pins 29 are fixedly installed in the mounting grooves. Abutment plates 26 are fixedly installed at the bottom of each of the two pressure plates 4. The bottom ends of the two abutment plates 26 are provided with a fourth inclined surface, and the bottom ends of the two abutment plates 26 extend into the grooves. The pressure plate 26 has a through hole, and the telescopic end of the electromagnetic pin 29 extends into the through hole. The telescopic end of the electromagnetic pin 29 can extend into the through hole of the pressure plate 26. After the pressure plate 26 presses against the clamping seat 24 to clamp the part, the electromagnetic pin 29 extends and inserts into the through hole of the pressure plate 26, fixing the pressure plate 26 to the clamping seat 24. This prevents the pressure plate 26 from loosening due to vibration during processing, ensuring firm clamping and improving processing stability. During unloading, the electromagnetic pin 29 retracts, releasing the fixation. The telescopic ends of the two hydraulic cylinders 5 drive the movable frame 21 to descend via the pressure plate 4, simultaneously compressing the first spring 23. The second rollers 27 on the two clamping seats 24 first contact the surface of the shaft-like parts. As the descent continues, the shaft-like parts contact the second rollers... Shaft 27 generates a lateral force, pushing the two clamps 24 to slide away from each other along the guide rod 28, while compressing the second spring 25. Under the guidance of the second roller 27, the shaft part automatically centers itself between the two clamps 24. When the movable frame 21 descends to the lowest position in the hopper 6, it stops moving downward. At this time, the telescopic end of the hydraulic cylinder 5 continues to extend downward, driving the pressure plate 4 to continue to descend. The pressure plate 26 at the bottom of the pressure plate 4 moves downward accordingly, and its fourth inclined surface at the bottom contacts the third inclined surface at the bottom of the groove of the clamp 24 and generates pressure, pushing the two clamps 24 to move synchronously towards the shaft part along the guide rod 28. As the clamps 24 continue to press, the shaft part is smoothly lifted and clamped by the second roller 27.

[0024] The moving mechanism 9 includes multiple second cylinders 94, a moving frame 91, multiple rollers 92, multiple sprockets 97, and two chain belts 98. The moving frame 91 is slidably mounted on the outer wall of one side of the two transport frames 8 that are close to each other. The moving frame 91 is provided with multiple strip grooves, and a first roller 93 is rotatably mounted in each of the multiple strip grooves. The multiple second cylinders 94 are respectively fixedly mounted on the outer wall of one side of the two transport frames 8 that are close to each other. The second cylinders 94 can drive the moving frame 91 to rise and fall along the outer wall of the transport frame 8 through their telescopic ends, thereby ensuring that the circular opening on the hopper 6 is in a horizontal position with the chuck on the lathe 1. The telescopic ends of the multiple second cylinders 94 are all fixedly connected to the moving frame 91. Multiple rotating shafts 96 are rotatably mounted on both outer walls of the transport frame 91. Multiple rollers 92 are fixedly mounted on the outer walls of the multiple rotating shafts 96. Multiple sprockets 97 are fixedly mounted on the bottom ends of the multiple rotating shafts 96. Two chain belts 98 are respectively sleeved on the outside of the multiple sprockets 97 and mesh with the multiple sprockets 97. Two first motors 95 are fixedly mounted on the bottom of the moving frame 91. The output shafts of the two first motors 95 are fixedly connected to the bottom ends of two of the rotating shafts 96. A support plate is fixedly mounted on the outer wall of the transport frame 8 away from the moving frame 91. A first cylinder 7 is fixedly mounted on the outer wall of one side of the support plate. The telescopic end of the first cylinder 7 extends into the transport frame 8 and a push plate 10 is fixedly mounted thereon.

[0025] In this embodiment: First, roll the single shaft parts piled on the ground into the lifting base 3. Align the hopper 6 with the entrance of the transport frame 8, push it into the transport frame 8, and let it slide along the inner wall of the transport frame 8 into the lifting base 3. During the sliding of the hopper 6, the end of the retaining shaft 12 in the limiting seat 11 first contacts the retaining plate 13 on the top of the lifting base 3. Under the pressure of the retaining plate 13, the retaining shaft 12 retracts into the limiting seat 11, and at the same time compresses the third spring 30. When the hopper 6 has completely fallen into the lifting base 3 and is in place, the retaining shaft 12 aligns with the retaining hole on the retaining plate 13, the third spring 30 resets, pushes the retaining shaft 12 through the retaining hole and extends into the guide groove, and the hopper 6 is locked in the lifting base 3 to prevent the hopper 6 from shifting when the lifting base 3 rises. After confirming that the hopper 6 is fixed in the lifting base 3, start the two hydraulic cylinders 5. The telescopic ends of the two hydraulic cylinders 5 drive the movable frame 21 to descend through the pressure plate 4, and at the same time compress the first spring 23. The second rollers 27 on the two clamps 24 first contact the surface of the shaft parts. Upon contact and continued descent, the shaft parts exert a lateral force on the second roller 27, pushing the two clamps 24 to slide away from each other along the guide rod 28. Simultaneously, the second spring 25 is compressed. Under the guidance of the second roller 27, the shaft parts automatically center themselves between the two clamps 24. When the movable frame 21 descends to the lowest position in the hopper 6, it stops moving downward. At this time, the telescopic end of the hydraulic cylinder 5 continues to extend downward, driving the pressure plate 4 to continue descending. The pressure plate 26 at the bottom of the pressure plate 4 moves downward accordingly, and its fourth inclined surface at the bottom contacts and squeezes the third inclined surface at the bottom of the groove of the clamp 24, pushing the two clamps 24 to move synchronously towards the shaft parts along the guide rod 28. As the clamps 24 continue to squeeze, the shaft parts are smoothly lifted and clamped by the second roller 27 until the pressure plate 26 can no longer move downward. The electromagnetic pin 29 is activated, and the telescopic end of the electromagnetic pin 29 extends and inserts into the through hole on the pressure plate 26, thus fixing the pressure plate 26 to the clamp 24. Then, the second motor 17 is started, driving the first gear 18 to mesh with the second gear 20, causing the first screw 16 to rotate. Since the two moving plates 14 are threadedly connected to the first screw 16, and the threads are opposite, the two moving plates 14 will slide in a direction away from each other. The lifting rod 15 drives the lifting base 3 to slowly rise in the transport frame 8. When the lifting base 3 slides to the top of the transport frame 8, the unlocking plate 19 slides into the guide groove, pressing the locking shaft 12 back into the limiting seat 11 through the first inclined surface, unlocking the hopper 6. Then, the first cylinder 7 is started. The telescopic end of the first cylinder 7 drives the push plate 10 to push the hopper 6 into the moving frame 91. The first cylinder 7 is closed, and the second cylinder 94 is started. The second cylinder 94 drives the moving frame 91 to slide upward along the outer wall of the transport frame 8 through its telescopic end, ensuring that the circular opening on the hopper 6 is aligned with the chuck on the lathe 1. In a horizontal position, the first motor 95 is started, and its output shaft drives the rotating shaft 96 to rotate. The sprocket 97 on the rotating shaft 96 drives all rotating shafts 96 to rotate synchronously through the chain belt 98. The roller 92 rotates with the rotating shaft 96 and drives the hopper 6 to move along the axial direction. After moving to the clamping position, the first motor 95 is turned off, and the two hydraulic cylinders 5 are started. The two hydraulic cylinders 5 drive the movable frame 21 to rise through the telescopic end, lifting the shaft parts to the center of the two circular openings. Then, the two transport frames 8 are moved so that the movable frame 91 moves towards the clamping plate. The clamping plate clamps the shaft parts. Then, the hydraulic cylinders 5 are started, and the hydraulic cylinders 5 drive the movable frame 21 to fall to avoid obstruction between the two circular openings. The hydraulic cylinders 5 are turned off, and the transport frames 8 are moved towards the clamping plate to ensure that the clamping plate completely passes through the two circular openings. Then, the shaft parts are drilled and milled. After processing, the transport frame 8 is moved away from the clamp, and the two hydraulic cylinders 5 are activated. The two hydraulic cylinders 5 drive the movable frame 21 to rise, and then the clamp is released, allowing the shaft parts to be placed on the two clamp seats 24. The first motor 95 is activated, and the roller 92 continues to move the hopper 6 to another lifting base 3. The hopper 6 is fixed to the lifting base 3 by the locking assembly. The second motor 17 is controlled to rotate in the opposite direction, causing the first screw 16 to rotate in the opposite direction. The two moving plates 14 will slide towards each other. The lifting rod 15 drives the lifting base 3 to slowly descend in the other transport frame 8. The electromagnetic pin 29 is closed, and the telescopic end of the electromagnetic pin 29 retracts. The hydraulic cylinder 5 drives the pressure plate 4 and the movable frame 21 to rise, and the pressure plate 26 moves away from the groove. At this time, the two clamp seats 24 return to their original positions by the second spring 25 and no longer clamp the shaft parts, completing the processing. The processed parts are then removed from the hopper 6 manually or by auxiliary equipment.

[0026] Second embodiment: The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Please refer to the following: Figures 13-18In the heavy-duty horizontal lathe drilling and milling integrated machining device provided in this embodiment, a storage box 36 is fixedly installed on the top of one of the transport frames 8. A partition is integrally formed inside the storage box 36, which divides the storage box 36 into two chambers. Two sets of lubrication components are provided on the storage box 36 and the transport frame 8. The lubrication components are used to reduce the resistance when the lifting base 3 rises.

[0028] The storage tank 36 is equipped with two observation ports, each with a fixed observation glass. The two observation ports correspond to two chambers respectively, allowing operators to visually observe the liquid level of the lubricating medium in the chambers.

[0029] Each lubrication assembly includes a one-way valve 37, a filling seat 35, an air bladder 41, a trapezoidal pressure block 38, and a trapezoidal abutment block 40. The filling seat 35 is fixedly installed on one side of the outer wall of the storage tank 36 and is connected to the chamber. An injection pipe 43 is fixedly installed on the top of the filling seat 35, and a sealing cap 44 is sealed on the top of the injection pipe 43. The one-way valve 37 is fixedly installed on the top of the sealing cap 44. The core function of the one-way valve 37 is to achieve one-way airflow. When the air bladder 41 returns to its original state and generates negative pressure, the one-way valve 37 opens, allowing outside air to smoothly enter the air bladder 41 to replenish the internal air pressure and prepare for the next lubrication action. When the air bladder 41 is compressed, the one-way valve 37 closes to prevent backflow of air inside the air bladder 41 and ensure that the air pressure can effectively drive the lubrication process. The lubricating oil in the storage tank 36 is delivered to the lubrication point. Two oil drain pipes 34 are located within the chamber, with the other ends extending into the transport frame 8. A rectangular groove is provided on one outer wall of the transport frame 8, and an airbag 41 is fixedly installed within it. One end of an air pipe 33 is fixedly installed on the outer wall of the airbag 41, and the other end of the air pipe 33 is fixedly connected to the filling seat 35. A mounting seat 32 is fixedly installed on one outer wall of the transport frame 8, and a trapezoidal pressure block 38 is slidably installed through and within the mounting seat 32. A rectangular pressing plate is integrally formed on the end of the trapezoidal pressure block 38 near the airbag 41, and a fifth inclined surface is provided on the other end of the trapezoidal pressure block 38, extending beyond the mounting seat 32. Multiple fifth springs 42 are fixedly installed on the side of the rectangular pressing plate away from the airbag 41. At one end, the other ends of multiple fifth springs 42 are fixedly connected to the mounting base 32. An L-shaped rod 31 is fixedly installed on one outer wall of the lifting base 3. A limiting groove is provided on one inner wall of the L-shaped rod 31. A trapezoidal stop block 40 is rotatably installed in the limiting groove. The end of the trapezoidal stop block 40 near the trapezoidal pressure block 38 is provided with a sixth inclined surface. The bottom of the trapezoidal stop block 40 is provided with a receiving groove. A first fixing rod is fixedly installed in the receiving groove. A second fixing rod is fixedly installed in the limiting groove. One end of a fourth spring 39 is provided on the outer wall of the first fixing rod. The other end of the fourth spring 39 is provided on the outer wall of the second fixing rod. When the L-shaped rod 31 rises, the trapezoidal stop block 40 in the limiting groove of the L-shaped rod 31 moves upward accordingly. Since the bottom of the trapezoidal stop block 40 contacts the bottom inner wall of the limiting groove, the trapezoidal stop block 40... The trapezoidal abutment block 40 can only rotate upwards, not downwards. Its sixth inclined surface gradually contacts the fifth inclined surface of the trapezoidal pressure block 38. During the continued upward movement, the trapezoidal abutment block 40 presses against the trapezoidal pressure block 38, causing the trapezoidal pressure block 38 to slide closer to the airbag 41. At the same time, the rectangular pressing plate at one end of the trapezoidal pressure block 38 presses against the airbag 41. After the airbag 41 is compressed, the internal air is injected into the filling seat 35 through the air pipe 33, which pressures the lubricating oil in the storage tank 36 chamber, pushing the lubricating oil through the oil drain pipe 34 to the lubrication part in the transport frame 8. When the L-shaped rod 31 continues to rise and the trapezoidal abutment block 40 no longer contacts the trapezoidal pressure block 38, the airbag 41 recovers. During the recovery process, a negative pressure is generated, and air is drawn in from the outside through the one-way valve 37 to replenish the internal air pressure of the airbag 41.When the airbag 41 returns to its original position and the lifting base 3 descends, the L-shaped rod 31 and the trapezoidal stop 40 move down simultaneously. The bottom of the trapezoidal stop 40 contacts the top of the trapezoidal pressure block 38. Since the bottom of the trapezoidal stop 40 is in contact with the bottom inner wall of the limiting groove, it can only rotate upwards and cannot rotate downwards. At this time, the end of the trapezoidal stop 40 near the trapezoidal pressure block 38 is raised, and its sixth inclined surface does not make pressing contact with the fifth inclined surface of the trapezoidal pressure block 38. The trapezoidal pressure block 38 does not compress the airbag 41, ensuring that lubricating oil is sprayed only when it rises. As the lifting base 3 continues to descend, the trapezoidal stop 40 completely disengages from the trapezoidal pressure block 38. Under the elastic pull of the fourth spring 39, it returns to the limiting groove of the L-shaped rod 31, maintaining its initial posture. This achieves synchronized lubrication during lifting, ensuring the lubrication needs of the sliding parts during the lifting process. When the lifting base 3 descends, the trapezoidal stop 40, due to structural limitations, cannot rotate downwards and has no squeezing contact with the trapezoidal pressure block 38, thus not driving the airbag 41 to move. This avoids ineffective consumption of the lubricating medium and achieves lubrication on demand.

[0030] The transport frame 8 is equipped with multiple oil inlet grooves, and the two oil drain pipes 34 located inside the transport frame 8 are both installed in the oil inlet grooves.

[0031] The outer wall of the one-way valve 37 is provided with two annular grooves, and a rubber ring is fixedly installed in each of the two annular grooves. The outer walls of the two rubber rings are in contact with the inner wall of the injection pipe 43. The rubber rings can prevent air from leaking from the gaps, ensure that the air bag 41 can effectively generate negative pressure to draw in air when it recovers, and at the same time prevent the lubricating medium in the storage tank 36 from overflowing through the gaps, thereby reducing medium waste and equipment contamination.

[0032] In this embodiment: When the second motor 17 meshes with the first gear 18 and the second gear 20, it drives the first screw 16 to rotate, causing the two moving plates 14 to move closer to each other. When the lifting rod 15 pushes the lifting base 3 to rise within the transport frame 8, it will drive the L-shaped rod 31 on one side to rise synchronously. The trapezoidal block 40 in the limiting groove of the L-shaped rod 31 moves upward accordingly. Since the bottom of the trapezoidal block 40 is in contact with the bottom inner wall of the limiting groove, the trapezoidal block 40 can only rotate upward and cannot rotate downward. Its sixth inclined surface gradually contacts the fifth inclined surface of the trapezoidal pressure block 38. During the continued upward movement, the trapezoidal block 40 compresses the trapezoidal... Pressing block 38 causes the trapezoidal pressing block 38 to slide closer to the airbag 41. At the same time, the rectangular pressing plate at one end of the trapezoidal pressing block 38 squeezes the airbag 41. After the airbag 41 is compressed, the internal air is injected into the filling seat 35 through the air pipe 33, which causes the lubricating oil in the storage box 36 to be pressurized. The lubricating oil is pushed through the oil drain pipe 34 to the lubrication part in the transport frame 8. When the L-shaped rod 31 continues to rise and the trapezoidal abutment block 40 no longer contacts the trapezoidal pressing block 38, the airbag 41 recovers. During the recovery process, negative pressure is generated, and air is drawn from the outside through the one-way valve 37 to replenish the internal air pressure of the airbag 41. The airbag 41 returns to its original state. When the lifting base 3 descends, the L-shaped rod 31 and the trapezoidal stop 40 move down simultaneously. The bottom of the trapezoidal stop 40 contacts the top of the trapezoidal pressure block 38. Since the bottom of the trapezoidal stop 40 is in contact with the bottom inner wall of the limiting groove, it can only rotate upward and cannot rotate downward. At this time, the end of the trapezoidal stop 40 close to the trapezoidal pressure block 38 is raised. Its sixth inclined surface does not squeeze into contact with the fifth inclined surface of the trapezoidal pressure block 38. The trapezoidal pressure block 38 does not compress the airbag 41, ensuring that lubricating oil is sprayed only when it rises. As the lifting base 3 continues to descend, the trapezoidal stop 40 and the trapezoidal pressure block 38 completely separate. Under the elastic tension of the fourth spring 39, it returns to the limiting groove of the L-shaped rod 31, maintains the initial posture, and completes the work of spraying lubricating oil on the inner wall of the transport frame 8.
