Description

Technical Field

[0001] This invention relates to the field of pipe fitting manufacturing technology, and in particular to a flat-end assembly and a flat-end machine and method for processing pipe fittings. Background Technology

[0002] In the field of pipe fitting processing, the quality of end-cutting directly affects the subsequent connection, installation, and overall performance of the pipe fittings. Traditional end-cutting equipment has many inconveniences when processing pipe fittings of different diameters. On the one hand, it is difficult to adjust the blade spacing. Pipe fittings of different diameters require blades with different spacing for end-cutting. However, traditional equipment usually lacks a convenient and effective blade spacing adjustment mechanism. As a result, when processing pipe fittings of different diameters, a lot of time and effort is required to adjust the blade position, and some parts may even need to be disassembled, which seriously affects processing efficiency.

[0003] Furthermore, traditional flat-end milling equipment lacks effective limiting and debris collection devices during processing. Without accurate limiting during pipe fitting processing, the cutting blade may not be able to precisely machine the pipe fitting end, leading to dimensional deviations. At the same time, if the debris generated during processing is not collected and disposed of in a timely manner, it will not only pollute the working environment but may also enter the equipment, affecting its normal operation and service life. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing methods that cannot adjust the blade spacing according to the pipe diameter, cannot accurately control the processing precision of the pipe end, and cannot collect and process debris in a timely manner. Therefore, this invention proposes a flat-end assembly and a flat-end machine and method for processing pipe fittings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flat-mouth assembly, comprising:

[0007] A housing, in which a motor is fixedly installed; a drive cylinder, fixed to the output shaft of the motor and rotatably connected to the housing; a drive shaft, slidably connected inside the drive cylinder; a drive disc, fixed to one end of the drive shaft; two blades, disposed on one side of the drive disc; and an adjustment structure, including:

[0008] A rotating ring (No. 1) is rotatably fitted onto the outer wall of the drive shaft; a tube is fixedly inserted through the drive shaft; an oil reservoir is located inside the drive shaft and extends axially; multiple connecting holes are located between the rotating ring (No. 1) and the drive shaft, allowing the rotating ring (No. 1) to communicate with the oil reservoir; a hole radially connects the oil reservoir and the tube; two U-shaped rods are slidably connected to both ends of the tube; a sliding groove is located on the side of the drive disc away from the drive shaft; two mounting seats are slidably connected within the sliding groove and fixedly connected to the two U-shaped rods respectively; when hydraulic oil is injected into or extracted from the rotating ring (No. 1), the hydraulic oil enters or exits the tube through the connecting holes, the oil reservoir, and the hole, driving the U-shaped rods to move the mounting seats in opposite directions or away from each other to adjust the distance between the two blades.

[0009] In one possible design, the adjustment structure further includes:

[0010] A hydraulic cylinder is fixedly embedded in the base; a hydraulic cylinder is sealed and slides through the hydraulic cylinder; a fixing plate is fixed to the top of the hydraulic cylinder; a connecting hose connects the hydraulic cylinder to the No. 1 rotating ring; wherein, the hydraulic oil driven by the lifting and lowering of the hydraulic cylinder is injected into or withdrawn from the No. 1 rotating ring through the connecting hose.

[0011] Pipe fitting finishing machine, including the above-mentioned finishing assembly, also includes:

[0012] Base plate; base, fixed to the top of the base plate; protective cover, fixed to the top of the base, housing the outer shell, drive cylinder and drive disc; frame, fixed to the top of the base and adjacent to the protective cover; two clamping blocks, slidably connected to the frame, arranged vertically; wherein, the lower clamping block is fixedly connected to the fixed plate, and when the clamping block clamps the pipe body, it drives the hydraulic cylinder to rise and fall to synchronously adjust the blade spacing.

[0013] In one possible design, the frame body is equipped with a clamping structure:

[0014] Two movable slots are respectively located on the inner walls of the top and bottom of the frame; a threaded rod, with its top threaded through the frame and its bottom rotatably connected to the clamping block located above; two rotating disks are rotatably located on both sides of the frame; four traction rods are respectively located in four strip slots and fixed to the corresponding two clamping blocks; four connecting rods are respectively hinged at both ends to the eccentric positions of the traction rods and the rotating disks; wherein, rotating the threaded rod drives the clamping block located above to move downward, and through the linkage of the rotating disks and connecting rods, the two clamping blocks move towards each other to clamp the pipe fitting.

[0015] One possible design also includes:

[0016] A limiting plate, sliding through the protective cover, extends at one end into the protective cover to limit the pipe body; a lifting structure, including:

[0017] The push plate is slidably disposed in the rectangular groove of the protective cover; the No. II rotating ring is fixed to the bottom end of the push plate and rotatably fitted with a drive shaft, which is fixed to the No. I rotating ring; the electric push rod is fixed to the top of the protective cover, and its output shaft is connected to the push plate; the sliding seat is fixed to the top of the push plate; the connecting rod is hinged at both ends to the sliding seat and the limiting plate respectively; wherein, when the electric push rod drives the push plate to move the drive disc toward the pipe, the connecting rod pulls the limiting plate to move upward to release the limiting.

[0018] One possible design also includes:

[0019] Two clearance slots are located on the side of the frame away from the protective cover; two connecting plates are slidably located in the clearance slots, with one end fixed to the clamping block located below; a support base is fixed to the other end of the two connecting plates; two support rods are slidably connected to the base at the bottom and fixed to the bottom of the connecting plate at the top; wherein, when the clamping block located below moves, it drives the support base to rise and fall via the connecting plate to support the pipe body.

[0020] One possible design also includes:

[0021] A collection trough is located at the top of the base; an inclined plate is fixed at an angle inside the collection trough; a discharge port is located on one side of the base and connected to the lowest end of the inclined plate; an L-shaped plate slides through the protective cover on the side away from the rotating door; multiple guide rods are fixed to the protective cover and slide through the L-shaped plate; a tension spring is sleeved on the guide rods and fixed at both ends to the protective cover and the L-shaped plate; multiple arc-shaped plates are fixed to one side of the limiting plate; a striking rod is fixed to the L-shaped plate and one end contacts the bottom of the inclined plate; when the limiting plate moves down, the arc-shaped plate squeezes the L-shaped plate to compress the tension spring, and the tension spring rebounds to drive the L-shaped plate to reciprocate, causing the striking rod to strike the inclined plate to vibrate and discharge chips.

[0022] In one possible design, a laser rangefinder is fixed inside the protective cover to detect the distance the pusher moves in order to control the blade feed rate.

[0023] In one possible design, the protective cover has a rotating door on the side near the discharge port.

[0024] The method of using the pipe fitting processing flat-end machine in this application includes the following steps:

[0025] S1. Pipe Fitting Positioning and Limiting: Insert the pipe fitting body into the frame and into the protective cover, where it is limited by the limiting plate;

[0026] S2, pipe clamping: Rotating the threaded rod drives the upper clamping block to move down. The two clamping blocks located above and below move in opposite directions through the rotating disk and connecting rod to clamp the pipe body. The lower clamping block lifts the far end of the pipe to ensure it is horizontal through the connecting plate and support seat.

[0027] S3, Adaptive blade adjustment: When the clamping block located below moves, it drives the hydraulic cylinder through the fixed plate. The hydraulic cylinder injects the oil in the hydraulic cylinder into the No. 1 rotating ring and the oil storage chamber of the drive shaft through the connecting hose, and then injects it into the tube to drive the U-shaped rod to move the mounting seat in the opposite direction, adjusting the blade position to match the diameter of the tube.

[0028] S4. Cutting process: Start the motor to drive the drive cylinder to rotate the drive shaft, drive disc and blade; start the electric push rod to push the push plate through the No. II rotating ring to drive the drive shaft and blade to feed the cutting towards the pipe fitting. At the same time, the push plate drives the limit plate to move up through the connecting rod to release the limit; the laser rangefinder monitors the movement of the push plate and controls the cutting amount; the chips fall to the inclined plate.

[0029] S5. Reset and chip removal: The electric push rod drives the push plate to reset; the push plate drives the limit plate to move down via the connecting rod, and the limit plate drives the L-shaped plate to reciprocate through the arc plate, L-shaped plate and tension spring, so that the striking rod strikes the inclined plate to vibrate and remove chips, and the chips are discharged through the discharge port.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] In this invention, multiple connecting holes are provided inside the No. I rotating ring and on the drive shaft. The No. I rotating ring is connected to the oil storage chamber through the connecting holes, and the oil storage chamber is connected to the tube through the holes. Both ends of the tube are sealed and slidably connected with U-shaped rods. The ends of the two U-shaped rods that are close to each other slide into the sliding groove and are respectively fixedly connected to the two mounting seats. By injecting or extracting hydraulic oil into the No. I rotating ring, the two blades can be controlled to move towards each other under the action of the No. I rotating ring being connected to the tube through the connecting holes, the oil storage chamber, and the holes. This allows the position of the blades to be adjusted according to the diameter of the tube body, thereby enabling end processing of tube bodies of different diameters.

[0032] In this invention, a hydraulic cylinder is slidably sealed inside the hydraulic cylinder, and a fixing plate is fixed to the top of the hydraulic cylinder. A connecting hose is fixed to one side of the hydraulic cylinder, and one end of the connecting hose is fixedly connected to the No. I rotating ring. Two clamping blocks arranged vertically are slidably connected inside the frame, and the lower clamping block is fixedly connected to the fixing plate. The upper and lower clamping blocks can move towards each other through the cooperation of the rotating disk and the connecting rod, thereby completing the clamping operation of the pipe body. When the lower clamping block moves, the hydraulic cylinder is raised and lowered through the fixing plate, thereby controlling the amount of hydraulic oil in the pipe cylinder and adjusting the distance between the two blades, which enables end processing of pipe bodies of different diameters.

[0033] In this invention, a limiting plate slides through the protective cover, and a push plate is slidably connected in the rectangular groove. The push plate is rotatably connected to the outer wall of the drive shaft via a rotating ring II. The top of the push plate is rotatably connected to the limiting plate via a connecting rod. When the pipe body passes through the frame and is clamped, the limiting plate limits the pipe body, which facilitates precise cutting of one end of the pipe body later. When the electric push rod drives the drive plate to move for end processing via the push plate, the push plate drives the limiting plate to move up through the connecting rod, thus preventing the limiting plate from obstructing the subsequent processing of the pipe body end by the blade.

[0034] In this invention, an L-shaped plate slides through the protective cover on the side away from the rotating door. The two ends of the tension spring are fixedly connected to the protective cover and the L-shaped plate, respectively. A plurality of arc-shaped plates that cooperate with the L-shaped plate are fixed on one side of the limiting plate. A striking rod is fixed on one side of the L-shaped plate. The push plate drives the limiting plate to move down through the connecting rod. The limiting plate can drive the L-shaped plate to move back and forth through the cooperation of the arc-shaped plate, the L-shaped plate and the tension spring. The L-shaped plate continuously strikes the bottom of the inclined plate through the striking rod, causing the inclined plate to vibrate, thereby discharging the debris on the inclined plate to the outside for collection through the discharge port.

[0035] In this invention, the blade spacing can be adjusted to quickly adapt to the processing requirements of pipes with different diameters; the pipe clamping is stable, ensuring processing accuracy; the limit is accurate, realizing automatic coordination between limit and processing; the chip collection effect is good, keeping the working environment clean; the operation is convenient, reducing the difficulty of operation and improving work efficiency.

Detailed Implementation

[0049] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0050] In one embodiment: Refer to Figures 1-3 The flat-mouth assembly relates to the field of pipe fitting production technology and mainly includes a housing 1, a motor, a drive cylinder 2, a drive shaft 3, a drive disc 4, a blade 7, and an adjustment structure.

[0051] Reference Figure 1 The housing 1 provides support and protection for the entire assembly. It is made of high-strength metal materials, such as stainless steel, which has good rigidity and corrosion resistance, effectively protecting the internal components from the influence of the external environment. The housing 1 is designed in a cuboid shape, with sufficient internal space to install the motor and other components.

[0052] Reference Figure 1 and Figure 2 The motor is fixedly installed inside the housing 1, and its power is selected according to actual processing requirements, generally between 500W and 2000W. The motor's output shaft extends rotatably to one side of the housing 1 and is fixed to the drive cylinder 2 by a key connection. The drive cylinder 2 is rotatably connected to one side of the housing 1 through bearings, ensuring that the drive cylinder 2 can rotate smoothly. The drive cylinder 2 adopts a cylindrical design, and its inner diameter is slightly larger than the diameter of the drive shaft 3 so that the drive shaft 3 can slide within it.

[0053] Reference Figures 1-3 The drive shaft 3 is slidably connected inside the drive cylinder 2, and a drive disc 4 is fixed to one end of it. The drive disc 4 is circular. Two blades 7 are provided on one side of the drive disc 4. The blades 7 are mounted on the mounting base 6 by fixing bolts 8, and the mounting base 6 is connected to the adjustment structure on the drive shaft 3. The blades 7 are made of high-hardness alloy material, such as cemented carbide, and have a sharp cutting edge and good wear resistance, enabling efficient cutting of pipe ends.

[0054] Reference Figures 1-4 The adjustment structure is the core component of the flat-mouth assembly, comprising a rotating ring I 13, a tube 16, an oil reservoir, connecting holes 14, orifices, and a U-shaped rod 15. The rotating ring I 13 is rotatably fitted onto the outer wall of the drive shaft 3, its inner diameter matching the outer diameter of the drive shaft 3 to ensure flexible rotation. Multiple connecting holes 14 are provided both inside the rotating ring I 13 and on the drive shaft 3 for injecting hydraulic oil from the rotating ring I 13 into the oil reservoir, and the rotating ring I 13 and the oil reservoir are connected through the connecting holes 14. The oil reservoir is located inside the drive shaft 3. The oil reservoir is connected to the tube 16 through orifices for injecting hydraulic oil into the tube 16.

[0055] Reference Figures 1-4 The tube 16 is fixedly inserted through the drive shaft 3, and both ends of it are slidably connected to U-shaped rods 15. The U-shaped rods 15 are made of high-strength steel and have good toughness and resistance to deformation. The drive disc 4 has a sliding groove 5 on the side away from the drive shaft 3, and two mounting seats 6 are slidably connected in the sliding groove 5. The ends of the two U-shaped rods 15 that are close to each other both extend slidably into the sliding groove 5 and are fixedly connected to the two mounting seats 6 respectively.

[0056] Specifically, when hydraulic oil is injected into or extracted from the rotating ring 13, the hydraulic oil enters the oil storage chamber through the connecting hole 14, and then enters the tube 16 through the hole, pushing the U-shaped rod 15 to move, thereby controlling the two mounting seats 6 to move towards each other, and realizing the adjustment of the distance between the two blades 7.

[0057] Reference Figure 3 The mounting base 6 has two internally threaded fixing bolts 8, both of which penetrate the blade 7, used to secure the mounting base 6 to the blade 7. The fixing bolts 8 are made of stainless steel and are M4-M8 in size, ensuring that the blade 7 can be firmly fixed to the mounting base 6.

[0058] Reference Figure 1 and Figure 2 To facilitate control of hydraulic oil injection and extraction, the adjustment structure also includes a hydraulic cylinder 9, a hydraulic cylinder 10, a fixing plate 11, and a connecting hose 12. The hydraulic cylinder 10 is slidably inserted through the hydraulic cylinder 9, and the fixing plate 11 is fixed to the top of the hydraulic cylinder 10. A connecting hose 12 is fixed to one side of the hydraulic cylinder 9, and one end of the connecting hose 12 is fixedly connected to the rotating ring 13. The hydraulic cylinder 9 is made of high-strength plastic or metal. The lifting and lowering of the hydraulic cylinder 10 allows for the injection or extraction of hydraulic oil into or from the rotating ring 13, thereby adjusting the distance between the two blades 7.

[0059] Reference Figures 6-8 The pipe fitting processing flat-end machine includes the above-mentioned flat-end component, and also includes a base plate 48, a base 17, a protective cover 18, a frame 20, a clamping block 23, a clamping structure, a limiting plate 38, a lifting structure, and other parts.

[0060] Reference Figure 6 and Figure 7 The base plate 48 provides a stable support foundation for the entire finishing machine. It is made of thick steel plate to ensure the machine does not shake during operation. The base 17 is fixed to the top of the base plate 48. The base 17 is made of cast iron and has good rigidity and shock absorption performance. A protective cover 18 is fixed to the top of the base 17. The outer shell 1, drive cylinder 2, and drive disc 4 are all located inside the protective cover 18. The protective cover 18 protects the internal components and prevents chips from flying. The protective cover 18 is made of transparent plastic or metal mesh, allowing operators to easily observe the processing.

[0061] Reference Figures 7-9The hydraulic cylinder 9 is fixedly embedded in the top of the base 17, and the frame 20 is fixed to one side of the protective cover 18 and connected to the top of the base 17. Two clamping blocks 23 arranged vertically are slidably connected inside the frame 20, and the two clamping blocks 23 are used to clamp the pipe body 21. The lower clamping block 23 is fixedly connected to the fixing plate 11 and is used to control the lifting and lowering of the hydraulic cylinder 10 when the clamping block 23 clamps the pipe body 21, thereby controlling the two blades 7 to perform end processing on pipe bodies 21 of different diameters.

[0062] Reference Figure 8 A clamping structure is installed inside the frame 20 to drive two clamping blocks 23 to move towards each other and smoothly clamp the pipe body 21. The clamping structure includes two movable grooves 22 located on the top and bottom inner walls of the frame 20, with the two clamping blocks 23 slidably disposed within each groove. A threaded rod 24 is rotatably connected to the top of the upper clamping block 23, with its threaded tip threaded through the frame 20 and extending to the top of the frame 20. Two strip grooves 28 are provided on each side of the frame 20, and all four strip grooves 28 are connected to their respective movable grooves 22. Traction rods 25 are slidably connected within each of the four strip grooves 28, and each of the four traction rods 25 is fixedly connected to its respective clamping block 23. Rotary disks 26 are rotatably connected to both sides of the frame 20, and connecting rods 27 are rotatably sleeved on the outer walls of the two traction rods 25 on the same side, with each connecting rod 27 rotatably connected to the side of the rotating disk 26 that is off-center.

[0063] During operation, rotating the threaded rod 24 drives the upper clamping block 23 to move downwards. The two clamping blocks 23 can move towards each other through the cooperation of the rotating disk 26 and the connecting rod 27, thereby completing the clamping operation of the pipe body 21. When the lower clamping block 23 moves, the hydraulic cylinder 10 is raised and lowered through the fixing plate 11, thereby controlling the amount of hydraulic oil in the pipe cylinder 16, and thus adjusting the distance between the two blades 7, enabling end processing of pipe bodies 21 with different diameters.

[0064] Reference Figure 7 The limiting plate 38 slides through the protective cover 18, with one end extending into the protective cover 18, and is used to limit one end of the pipe body 21, so that the blade 7 can accurately complete the end processing of the pipe body 21 later.

[0065] Reference Figure 7 and Figure 10A lifting structure is installed inside the protective cover 18. This structure releases the limiting plate 38 from the pipe body 21 when the drive disc 4 moves towards the pipe body 21 for port processing, allowing the blade 7 to perform processing smoothly. The lifting structure includes a rectangular groove 33 within the protective cover 18, with a push plate 34 slidably connected within it. A rotating ring 49 (No. II) is fixed to the bottom of the push plate 34 and is rotatably fitted onto the outer wall of the drive shaft 3. One side of the rotating ring 49 is fixedly connected to a rotating ring 13 (No. I), allowing the drive shaft 3 and drive disc 4 to move via the rotating rings 49 and 13 when the push plate 34 moves, thus completing the processing of the pipe body 21 port by the blade 7. An electric push rod 35 is fixed to the top inner wall of the protective cover 18 via a base, and the output shaft of the electric push rod 35 is fixedly connected to the push plate 34. A laser rangefinder 39 is fixed to the inner wall of the protective cover 18 on the side away from the frame 20. It is used to detect the distance the push plate 34 moves, thereby controlling the feed distance of the blade 7. A sliding seat 36 is fixed to the top of the push plate 34, and the sliding seat 36 slides on the top of the protective cover 18. The top of the sliding seat 36 is rotatably connected to one side of the limiting plate 38 through a connecting rod 37. When the push plate 34 drives the drive disk 4 to move towards the pipe body 21 for processing, it can drive the limiting plate 38 to move upward and release the limitation on the pipe body 21.

[0066] During operation, when the pipe body 21 is inserted through the frame 20 and clamped, the limiting plate 38 limits the pipe body 21, facilitating precise cutting of one end of the pipe body 21 later. When the electric push rod 35 drives the drive plate 4 to move for end processing via the push plate 34, the push plate 34 drives the limiting plate 38 upward via the connecting rod 37, preventing the limiting plate 38 from obstructing the subsequent processing of the pipe body 21 end by the blade 7.

[0067] Reference Figure 6 and Figure 8 The frame 20 has two clearance slots 29 on the side away from the protective cover 18. A connecting plate 30 is slidably connected to each of the two clearance slots 29. One end of each connecting plate 30 is fixedly connected to a clamping block 23 located below, and the other end of each connecting plate 30 is fixed to the same support base 31, which supports the pipe body 21. The clamping block 23 below drives the support base 31 to rise and fall via the connecting plates 30, thus supporting the pipe body 21 and preventing tilting during the processing of the pipe body 21's ends. Support rods 32 are fixed to the bottom of each connecting plate 30, and the bottom ends of each support rod 32 are slidably connected to one side of the base 17, supporting the connecting plate 30.

[0068] Reference Figure 5 and Figure 11The base 17 has a collection groove 40 on its top for collecting debris generated during port processing. An inclined plate 41 is fixed inside the collection groove 40 to guide the debris to one side. A discharge port 42, connected to the collection groove 40, is located on one side of the base 17 and cooperates with the inclined plate 41 to discharge debris from the inclined plate 41 to the outside. A rotating door 19 is located on the side of the protective cover 18 near the discharge port 42 for later inspection and maintenance of the components inside the protective cover 18.

[0069] In another embodiment: Refer to Figure 11 and Figure 12 An L-shaped plate 44 slides through the side of the protective cover 18 away from the rotating door 19. Multiple guide rods 45 slide through the L-shaped plate, with one end of each guide rod 45 fixedly connected to one side of the protective cover 18. A tension spring 46 is fitted onto the outer wall of each guide rod 45. The parameters of the tension spring 46 are: wire diameter between 0.5mm and 1.5mm, outer diameter between 8mm and 20mm, free length between 20mm and 50mm, and working load between 5N and 20N. Both ends of the tension spring 46 are fixedly connected to the protective cover 18 and the L-shaped plate 44 respectively by bolts. Multiple arc-shaped plates 43 that mate with the L-shaped plate 44 are fixed to one side of the limiting plate 38.

[0070] During operation, when the limiting plate 38 moves the arc plate 43 upward, the tension of the tension spring 46 drives the L-shaped plate 44 to reciprocate. A striking rod 47 is fixed on one side of the L-shaped plate. One end of the striking rod 47 slides into the collection groove 40 and touches the bottom of the inclined plate 41. It is used to strike the inclined plate 41 when the L-shaped plate 44 moves with the striking rod 47, and discharge the debris on it to the outside through the discharge port 42.

[0071] The push plate 34 drives the limiting plate 38 to move down through the connecting rod 37. The limiting plate 38, through the cooperation of the arc plate 43, the L-shaped plate and the tension spring 46, can drive the L-shaped plate 44 to move back and forth. The L-shaped plate continuously strikes the bottom of the inclined plate 41 through the striking rod 47, causing the inclined plate 41 to vibrate, thereby discharging the debris on the inclined plate 41 to the outside through the discharge port 42 for collection.

[0072] The operating method of a pipe fitting finishing machine includes the following steps:

[0073] S1. One end of the pipe body 21 passes through the frame 20 and extends into the protective cover 18. The limiting plate 38 can limit the pipe body 21, which makes it easier to accurately cut one end of the pipe body 21 later. Then, rotate the threaded rod 24. The threaded rod 24 drives the upper clamping block 23 to move down. The upper and lower clamping blocks 23 can move towards each other through the cooperation of the rotating disk 26 and the connecting rod 27, thereby completing the clamping operation of the pipe body 21. The lower clamping block 23 can lift the end of the pipe body 21 away from the frame 20 through the connecting plate 30 and the support seat 31, ensuring the horizontality of the pipe body 21 and avoiding tilting during the later end cutting.

[0074] S2. When the lower clamping block 23 moves, the hydraulic cylinder 10 is driven to rise and fall by the fixing plate 11. When the outer diameter of the pipe body 21 is large, the lower clamping block 23 drives the hydraulic cylinder 10 to move down by the fixing plate 11. The hydraulic cylinder 10 injects the hydraulic oil in the hydraulic cylinder 9 into the No. I rotating ring 13 through the connecting hose 12, and injects it into the oil storage chamber in the drive shaft 3 through the connecting hole 14. Then, the hydraulic oil in the drive shaft 3 is injected into the pipe cylinder 16 through the connecting hole 14. In this way, the two mounting seats 6 are driven to move in opposite directions by the U-shaped rod 15, so that the position of the blade 7 can be adjusted according to the diameter of the pipe body 21, thereby enabling end processing of pipe bodies 21 with different diameters.

[0075] S3. When port processing is performed, the motor inside the housing 1 drives the drive cylinder 2 to rotate. The drive cylinder 2 drives the drive disk 4 and the blade 7 to rotate through the drive shaft 3. Then, the output shaft of the electric push rod 35 pushes the push plate 34 to move. The push plate 34 drives the drive shaft 3 and the blade 7 to move towards the pipe body 21 through the rotating ring II 49 to complete the port processing operation. The laser rangefinder 39 can detect the moving distance of the push plate 34 to control the cutting amount of the pipe body 21. When the push plate 34 moves, it drives the limit plate 38 to move upward through the connecting rod 37 to release the obstruction on one end of the pipe body 21, which facilitates the subsequent processing of one end of the pipe body 21 by the blade 7.

[0076] S4. During the port processing, the processing debris falls onto the inclined plate 41. After processing is completed, the output shaft of the electric push rod 35 drives the push plate 34 to reset and move. The push plate 34 drives the limiting plate 38 to move down through the connecting rod 37. The limiting plate 38 can drive the L-shaped plate 44 to move back and forth through the cooperation of the arc plate 43, the L-shaped plate 44 and the tension spring 46. The L-shaped plate 44 continuously taps the bottom of the inclined plate 41 through the striking rod 47, causing the inclined plate 41 to vibrate, thereby discharging the debris on the inclined plate 41 to the outside for collection through the discharge port 42.
