Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and in particular to a grinding equipment for the production of new energy vehicle parts. Background Technology

[0002] In the field of new energy vehicle component manufacturing, pipe bends are key components connecting battery cooling systems, motor oil circuits, and brake lines. Pipe bends are typically manufactured using a one-piece casting process. The gate, serving as the channel for molten metal injection into the mold, inevitably leaves excess metal residue after molding. If not thoroughly removed, these sharp edges or protrusions can become stress concentration points, easily leading to fatigue cracks under long-term alternating loads, threatening structural safety.

[0003] Currently, most pipe bends are made of aluminum alloy. For grinding the gates of these aluminum alloy pipe bends, the common equipment is a disc grinder. This equipment is equipped with a rotary worktable with a special fixture that fits tightly to the shape of the pipe bend. Before grinding, the worker places the pipe bend to be ground in the fixture, then the rotary worktable rotates, transporting the pipe bend to the grinding area where the sanding belt automatically grinds the gate at its end. After grinding, the worktable rotates again, sending the pipe bend back to the loading / unloading station, where the worker removes it from the fixture. However, in actual operation, it has been found that when the sanding belt grinds the gate area of ​​the pipe bend at high speed, some thin layers of metal at the edge of the pipe bend end are not completely broken off after being thinned and stretched. Instead, they curl up and adhere to the edge of the pipe bend end in sheet or filament form. Currently, this mainly relies on manual secondary finishing for removal, which adds extra processing time and labor costs. Therefore, a grinding device for the production of new energy vehicle parts is needed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding device for the production of new energy vehicle parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A grinding device for the production of new energy vehicle parts includes a housing, a rotary worktable and a belt sander body installed inside the housing, and a mold for fixing a bent pipe joint installed on the top of the rotary worktable. The top of the inner wall of the housing is provided with a cleaning mechanism for cleaning the residue at the edge of the bent pipe joint. The cleaning mechanism includes a cleaning section, a driving section, and a reversing section; The cleaning unit includes a bracket, which is fixedly connected to the top of the inner wall of the housing. The bottom of the bracket is connected to a fixed frame via a first elastic telescopic rod. A first rotating groove is formed through the bottom of the inner wall of the fixed frame. A rotating tube is rotatably connected in the first rotating groove. A connector is fixedly sleeved on the outside of the rotating tube. A support groove is formed through one side of the front of the connector. A support block is provided inside the support groove. A scraper is fixedly connected to one side of the support block via a crossbar. The driving unit and the reversing unit cooperate to drive the rotating tube to perform lifting and rotating movements.

[0006] By adopting the above technical solution, when the bent pipe joint is transported to the bottom of the cleaning mechanism by the rotary worktable after grinding, the rotating tube moves up and down, so that the scraper can extend into the inside of the bent pipe joint and closely adhere to its end edge. By rotating and scraping, the flaky or filamentous metal residues remaining on the end edge of the bent pipe joint after sanding are completely removed, thus avoiding the tedious steps of manual secondary repair and effectively reducing process time and labor costs.

[0007] Preferably, the cleaning mechanism further includes an adjustment part, which includes a mounting ring fixedly sleeved on the outside of the rotating tube. A first ear is fixedly connected to one side of the mounting ring, and a first rotating shaft is rotatably connected inside the first ear. An adaptation plate is fixedly sleeved on the outside of the first rotating shaft. Two second rotating shafts are fixedly connected to the front and back of the adaptation plate and the support block. A connecting arm is rotatably sleeved on the outside of two adjacent second rotating shafts. The support block is slidably connected in the support groove. A second elastic telescopic rod is hinged between the adaptation plate and the rotating tube. A third rotating shaft is fixedly connected to both sides of the fixed section of the second elastic telescopic rod. A fourth rotating shaft is fixedly connected to both sides of the movable section of the second elastic telescopic rod. A second ear is fixedly connected to one side of the adaptation plate. A third ear is fixedly connected to the outside of the rotating tube. The third rotating shaft is rotatably connected to the inside of the third ear. The fourth rotating shaft is rotatably connected to the inside of the second ear. Sliding grooves are provided at the top and bottom of the inner wall of the support groove. Sliding blocks are fixedly connected to the top and bottom of the support block. The sliding blocks are slidably connected in the sliding grooves.

[0008] By adopting the above technical solution, the adapting plate can automatically adjust its tilt angle according to the actual size of the inner wall of the joint when it enters the bend joint of different diameters. With the help of the linkage between the connecting arm and the second rotating shaft, the horizontal sliding of the support block in the support groove is precisely controlled, thereby driving the scraper to move synchronously. This realizes the adaptive fitting of the scraper to bend joints of different diameters, significantly expands the processing application range of a single machine, and improves the versatility and flexibility of the machine.

[0009] Preferably, the adapting plate is inclined, with its bottom adjacent to the rotating tube and its top away from the rotating tube.

[0010] By adopting the above technical solution, the bottom of the adapting plate can smoothly enter the port of the bend joint first during the descent process. During the continuous descent, the inclined outer wall surface plays a guiding role, guiding the entire adapting plate and scraper to accurately enter the interior of the bend joint. This effectively reduces the difficulty of docking the scraper with the end of the bend joint, reduces the risk of equipment collision caused by misalignment, and improves the reliability of equipment operation.

[0011] Preferably, the cleaning mechanism further includes a lubrication unit, which includes a storage tank. A sealing cap is threaded onto the top of the storage tank. Multiple fixing pipes are fixedly connected to one side of the storage tank. One end of each fixing pipe is fixedly connected to one side of an adaptation plate. Multiple mounting grooves are provided on the other side of the adaptation plate. Ball bearings are embedded in the mounting grooves. Multiple flow grooves are provided through one side of the adaptation plate. The flow grooves are connected to the mounting grooves and the fixing pipes.

[0012] By adopting the above technical solution, the storage tank stores lubricating oil, and the lubricating oil is guided to the flow groove on one side of the adapting plate by a fixed pipe. Then, the lubricating oil is evenly coated on the inner wall surface of the elbow joint by the rolling contact of the ball embedded in the installation groove with the inner wall of the elbow joint. This effectively reduces the friction coefficient between the adapting plate, the scraper and the inner wall of the elbow joint, avoids damage to the inner wall of the elbow joint caused by the scraper's direct hard scraping, and reduces the wear rate of the adapting plate and the scraper, thus extending the service life of the cleaning mechanism.

[0013] Preferably, a plurality of connecting rings are fixedly connected to the inner side of the fixed pipe, and an oil-absorbing rope is fixedly connected inside the connecting rings. The oil-absorbing rope is located in the flow groove and the installation groove.

[0014] By adopting the above technical solution, the oil-absorbing rope continuously and slowly draws the lubricating oil in the fixed tube to the ball through capillary action, thereby achieving precise supply and quantity control of the lubricating oil. This ensures sufficient lubrication of the ball surface while avoiding excessive overflow and waste of lubricating oil.

[0015] Preferably, the driving unit includes a lifting tube, and a second rotating groove is provided through the top of the fixed frame. A first bearing and a second bearing are respectively installed in the first rotating groove and the second rotating groove. The lifting tube is rotatably connected to the second rotating groove through the second bearing, and the rotating tube is rotatably connected to the first rotating groove through the first bearing. The reversing unit includes a first bevel gear, which is fixedly sleeved on the outside of the lifting tube. The lifting tube is located inside the rotating tube. A second bevel gear is fixedly sleeved on the outside of the rotating tube. Horizontal shafts are rotatably connected to both sides of the inner wall of the fixed frame. Third bevel gears are fixedly sleeved on the outside of both horizontal shafts. The third bevel gears mesh with the first and second bevel gears. Multiple first springs are fixedly connected to one side of the inner wall of the storage tank. A sealing ball for sealing the fixed tube is fixedly connected to one end of each first spring. A magnetic block is fixedly connected to one side of the lifting tube. The sealing ball is made of magnetic material and is magnetically attracted to the magnetic block.

[0016] By adopting the above technical solution and combining it with the magnetic attraction control of the sealing ball and the magnetic block, oil supply is achieved only when the lifting pipe rotates to a specific angle, which further optimizes the intermittent supply strategy of lubricating oil and significantly reduces the consumption of lubricating oil and production costs.

[0017] Preferably, the drive unit further includes a rotating tube, a rotating groove is formed through the top of the bracket, the rotating tube is rotatably connected to the rotating groove via a third bearing, guide grooves are formed on both sides of the inner wall of the rotating tube, guide strips are fixedly connected to the top of both sides of the lifting tube, the guide strips are slidably connected to the guide grooves, a motor is installed on the top of the inner wall of the bracket, spur gears are fixedly sleeved on the output shaft of the motor and the outer side of the rotating tube, the two spur gears mesh, a worm gear is fixedly sleeved on the outer side of the rotating tube, a connecting frame is fixedly connected to one side of the inner wall of the bracket, a shaft groove is formed through both sides of the connecting frame, a first connecting shaft is rotatably connected in the shaft groove, and a first connecting shaft is fixedly sleeved on the outer side of the first connecting shaft. A worm gear is provided for cooperating with the worm. A rotating plate is fixedly connected to one end of the first connecting shaft. A vertical groove is opened on one side of the rotating plate, and an adjusting block is provided in the vertical groove. An ear plate is fixedly connected to one side of the inner wall of the bracket. A third connecting shaft is rotatably connected to the inner side of the ear plate. A lifting frame is fixedly sleeved on the outer side of the third connecting shaft. A fourth connecting shaft is rotatably connected to both sides of the inner wall of the lifting frame. A rotating ring is fixedly connected between the two fourth connecting shafts. A limiting ring is rotatably connected to the inner side of the rotating ring. The limiting ring is fixedly sleeved on the outer side of the lifting tube. A second connecting shaft is fixedly connected to one side of the adjusting block and the lifting frame. A swing arm is rotatably sleeved on the outer side of the two second connecting shafts.

[0018] By adopting the above technical solution, the scraper can perform stable periodic lifting and lowering while rotating, realizing the gradual scraping of the edge of the bend joint from top to bottom. This movement mode can effectively avoid the scraper jamming or bend joint damage caused by excessive scraping at one time, ensuring the stability and safety of the cleaning process.

[0019] Preferably, a circular groove is provided through the top of the rotating plate, and a lead screw is rotatably connected to the groove through a damping bearing. The lead screw is located in the vertical groove, and the adjusting block is threaded onto the outside of the lead screw and slidably connected in the vertical groove.

[0020] By adopting the above technical solution, the operator can precisely adjust the position of the adjusting block in the vertical groove by rotating the screw, change the rotation radius of the adjusting block, and thus adjust the swing amplitude of the swing arm and the rotation angle of the lifting frame. Ultimately, this achieves flexible adjustment of the lifting stroke of the lifting pipe and the rotating pipe, enabling the cleaning device to quickly adjust the scraping depth and path of the scraper according to the requirements of different types or sizes of bent pipe joints, greatly enhancing the operability of the equipment and its adaptability to different working conditions.

[0021] Preferably, an air pump is installed on the top of the bracket, and the air outlet of the air pump is fixedly connected to a jet pipe through a telescopic hose. The lifting pipe is rotatably sleeved on the outside of the jet pipe through a sealed bearing.

[0022] By adopting the above technical solution, the air pump delivers compressed air to the inside of the lifting pipe through the telescopic hose and the jet pipe, and finally sprays it out from the bottom of the rotating pipe. While the scraper cleans the residue, the high-speed airflow blows away the scraped but potentially fallen and accumulated residue at the bend of the pipe joint in time, effectively preventing the accumulation of residue inside the joint and avoiding the potential impact of residue residue on subsequent assembly or use, and further improving the internal cleanliness of the pipe joint after grinding.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting up a cleaning mechanism, the scraper can be inserted into the inside of the pipe joint to automatically rotate and scrape away the flaky or filamentous metal residues left on the edge of the pipe joint after grinding. This achieves automation and high efficiency in cleaning the residues left after grinding the end of the pipe joint, significantly reducing labor costs and improving production efficiency.

[0024] 2. By setting an adjustment part, the adaptation plate can be tilted and the second elastic telescopic rod can be elastically coordinated to make the adaptation plate self-adaptively deflect when it is inserted into the bend joints of different diameters. The horizontal position of the scraper can be precisely adjusted by the connecting arm, so that the scraper can closely fit the inner wall of the bend joints of different diameters, effectively expanding the cleaning capacity of the grinding device for bend joints of different specifications.

[0025] 3. By setting up a lubrication section, the storage tank, fixed pipe and ball bearings work together to lubricate the inner wall of the pipe bend joint as the scraper enters it. This effectively reduces the friction between the scraper and the pipe bend joint, which not only reduces scraper wear and extends its service life, but also prevents the scraper from scratching the inner wall of the pipe bend joint, thus ensuring the processing quality of the product.

[0026] 4. By setting up oil suction ropes and sealing balls, precise delivery and on-demand supply of lubricating oil are achieved, which not only ensures sufficient lubrication of the balls but also avoids waste of lubricating oil. At the same time, by utilizing the magnetic attraction between the magnetic blocks and the sealing balls, intermittent oil supply synchronized with the equipment's movement cycle is achieved, further optimizing the lubrication effect and reducing the consumption of auxiliary materials and operating costs in the production process.

[0027] 5. By setting up a drive unit, the periodic lifting and lowering motion of the lifting pipe is realized, which enables the scraper to gradually clean the residue in a combined rotation and lifting motion. This effectively avoids equipment overload or workpiece damage caused by excessive scraping in a single operation, and ensures the stability and reliability of the cleaning process.

[0028] 6. By setting up an air pump and a jet pipe, and rotatably connecting the jet pipe to the inside of the lifting pipe through a sealed bearing, a high-speed airflow can be blown into the inside of the bend joint while cleaning residue. This blows away the scraped residue from the bend of the joint in a timely manner, effectively preventing residue accumulation, ensuring the cleanliness of the inside of the bend joint after cleaning, and improving the final quality of the product.

[0029] 7. By setting a lead screw and adjusting block, the operator can easily adjust the position of the adjusting block on the rotating plate, thereby changing the lifting range of the lifting pipe. This allows the equipment to flexibly adjust the scraping stroke of the scraper according to the depth of different pipe joints, simplifying the equipment debugging process and improving the equipment's ability to respond quickly to different processing needs.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Reference Figures 1-11 A grinding device for the production of new energy vehicle parts includes a housing 1, a rotary worktable 2 and a belt sander body 4 installed in the housing 1, and a mold 3 for fixing a bent pipe joint installed on the top of the rotary worktable 2. A cleaning mechanism 5 is provided on the top of the inner wall of the housing 1 for cleaning the residue at the edge of the bent pipe joint. The cleaning mechanism 5 includes a cleaning unit 51, a drive unit 55, and a reversing unit 54; The cleaning unit 51 includes a bracket 5101, which is fixedly connected to the top of the inner wall of the housing 1. The bottom of the bracket 5101 is connected to a fixed frame 5103 via a first elastic telescopic rod 5102. A first rotating groove is provided through the bottom of the inner wall of the fixed frame 5103. A rotating tube 5104 is rotatably connected in the first rotating groove. A connector 5105 is fixedly sleeved on the outside of the rotating tube 5104. A support groove is provided through one side of the front of the connector 5105. A support block 5106 is provided inside the support groove. A scraper 5107 is fixedly connected to one side of the support block 5106 via a crossbar. The driving unit 55 and the reversing unit 54 cooperate to drive the rotating tube 5104 to perform lifting and rotating movements, so that the scraper 5107 can descend and move to the inside of the bent pipe joint and rotate. This facilitates the scraping and cleaning of the flaky or filamentous residues remaining at the end of the polished bent pipe joint by using the rotating scraper 5107, reducing process time and labor costs.

[0034] Furthermore, refer to Figures 5-8 It can be seen that the cleaning mechanism 5 also includes an adjustment part 52, which includes a mounting ring 5201. The mounting ring 5201 is fixedly sleeved on the outside of the rotating tube 5104. A first ear seat 5202 is fixedly connected to one side of the mounting ring 5201.

A connecting arm 5205 is rotatably sleeved on the outside of two adjacent second rotating shafts 5204. The support block 5106 is slidably connected in the support groove. A second elastic telescopic rod 5208 is hinged between the adaptation plate 5211 and the rotating tube 5104, so that the scraper 5107 can adapt to the bent pipe joints of different diameters, thus expanding the applicability of the device.

[0035] Furthermore, refer to Figures 5-8It can be seen that the fixed section of the second elastic telescopic rod 5208 is fixedly connected to both sides of the third rotating shaft 5209, the movable section of the second elastic telescopic rod 5208 is fixedly connected to both sides of the fourth rotating shaft 5210, the adapting plate 5211 is fixedly connected to one side of the second ear seat 5206, the rotating tube 5104 is fixedly connected to the outside of the third ear seat 5207, the third rotating shaft 5209 is rotatably connected to the inside of the third ear seat 5207, and the fourth rotating shaft 5210 is rotatably connected to the inside of the second ear seat 5206, thereby allowing the adapting plate 5211 to... After entering the bend joint, as the adapting plate 5211 gradually goes deeper, it can rotate around the first rotating shaft 5203. This allows the second rotating shaft 5204 and the connecting arm 5205 to push the support block 5106 to move within the support groove. The movement of the support block 5106 can drive the crossbar to move, and the movement of the crossbar can drive the scraper 5107 to move. This allows the scraper 5107 to be adapted to cleaning the residue at the ends of bend joints of different diameters, thus expanding the applicability of the scraper 5107.

[0036] Furthermore, refer to Figures 5-8 It can be seen that the adapting plate 5211 is inclined, with the bottom of the adapting plate 5211 adjacent to the rotating tube 5104 and the top of the adapting plate 5211 far from the rotating tube 5104, so that the adapting plate 5211 can more easily enter the inside of the bend joint when it moves downward.

[0037] Furthermore, refer to Figures 5-8 It can be seen that the top and bottom of the inner wall of the support groove are provided with sliding grooves, and the top and bottom of the support block 5106 are fixedly connected with sliders.

Ball bearings 5302 are embedded in the mounting grooves. Multiple flow grooves are opened through one side of the adaptation plate 5211. The flow grooves are connected to the mounting grooves and the fixed pipes 5303. This allows the lubricating oil in the storage tank 5301 to enter the mounting grooves and wet the ball bearings 5302, so that the ball bearings 5302 can contact the inner wall of the bend joint, further reducing the friction of the adaptation plate 5211 entering the bend joint and extending the service life of the adaptation plate 5211 and the scraper 5107.

A third bevel gear 5403 is fixedly sleeved on the outer side of each of the two horizontal shafts. The third bevel gear 5403 meshes with the first bevel gear 5401 and the second bevel gear 5402, so that when the lifting tube 5514 rotates, it can drive the first bevel gear 5401 to rotate. The rotation of the first bevel gear 5401 can drive the third bevel gear 5403 to rotate. The rotation of the third bevel gear 5403 can drive the second bevel gear 5402 to rotate. The rotation of the second bevel gear 5402 can drive the rotating tube 5104 to rotate, so that the lifting tube 5514 and the rotating tube 5104 can perform coaxial and reverse rotation.

[0042] Furthermore, refer to Figures 5-8It can be seen that multiple first springs 5307 are fixedly connected to one side of the inner wall of the storage tank 5301. One end of the first spring 5307 is fixedly connected to a sealing ball 5306 for sealing the fixed pipe 5303. A magnetic block 5309 is fixedly connected to one side of the lifting pipe 5514. The sealing ball 5306 is made of magnetic material, and the sealing ball 5306 and the magnetic block 5309 are magnetically attracted to each other, which facilitates further reduction of the amount of lubricating oil used and further reduces the production cost of the enterprise.

[0043] Furthermore, refer to Figure 9 It can be seen that the blocking ball 5306 is wrapped with a protective sleeve made of rubber, which facilitates the protection of the blocking ball 5306.

The adjusting block 5507 and the lifting frame 5511 are both fixedly connected to a second connecting shaft 5508 on one side. A swing arm 5509 is rotatably sleeved on the outer side of the two second connecting shafts 5508, which facilitates the lifting pipe 5514 and the rotating pipe 5104 to rotate and lift at the same time, thereby improving the cleaning effect on the residue on the bent pipe joint.

[0045] Furthermore, refer to Figure 5 , Figure 6 and Figure 10 It can be seen that a circular groove is opened through the top of the rotating plate 5506, and a lead screw 5520 is rotatably connected in the circular groove through a damping bearing. The lead screw 5520 is located in the vertical groove, and the adjusting block 5507 is threaded on the outside of the lead screw 5520 and slidably connected in the vertical groove. This makes it convenient for the staff to adjust the position of the adjusting block 5507, and thus convenient for the staff to adjust the lifting distance of the lifting tube 5514 and the rotating tube 5104.

[0046] Furthermore, refer to Figure 10 It can be seen that a knob is fixedly connected to the top of the lead screw 5520, and the outer side of the knob is provided with anti-slip texture to prevent the operator from slipping when turning the lead screw 5520.

[0047] Furthermore, refer to Figure 5 and Figure 6 It can be seen that an air pump 6 is installed on the top of the bracket 5101. The air pump 6 is existing technology and will not be described in detail here. The air outlet of the air pump 6 is fixedly connected to the jet pipe 7 through a telescopic hose. The lifting pipe 5514 is rotatably sleeved on the outside of the jet pipe 7 through the sealed bearing 8, so as to facilitate the delivery of gas through the lifting pipe 5514 to the bent pipe joint, thereby facilitating the blowing away of the residue that falls into the bent pipe joint and preventing the residue from accumulating in large quantities at the bend of the bent pipe joint.

[0048] Furthermore, refer to Figure 5 and Figure 11 It can be seen that the first elastic telescopic rod 5102 and the second elastic telescopic rod 5208 have the same structure, and the sleeve of the first elastic telescopic rod 5102 is fixedly connected to the bottom of the bracket 5101, and the bottom end of the slide rod of the first elastic telescopic rod 5102 is fixedly connected to the top of the fixed frame 5103. This will not be elaborated here.

[0049] In this invention, when the worker grinds the end of the bent pipe joint, the bent pipe joint can be installed in the mold 3. Then, the mold 3 and the bent pipe joint are transferred to the grinding area of ​​the belt sander body 4 by the rotary worktable 2 for grinding. The mold 3 and the bent pipe joint are then transferred to the cleaning mechanism 5 by the rotary worktable 2. At this time, the motor 5518 starts, and the rotating tube 5501 is driven to rotate by the cooperation of two spur gears 5519. The rotation of the rotating tube 5501 can drive the guide bar 5517 to rotate through the guide groove. The rotation of the guide bar 5517 can drive the lifting tube 5514 to rotate. The rotation of the lifting tube 5514 can drive the limiting ring 5515 to rotate. The rotation of the lifting tube 5514 drives the first bevel gear 5401 and the magnetic block 5309 to rotate. The rotation of bevel gear 5401 can drive the rotation of third bevel gear 5403, the rotation of third bevel gear 5403 can drive the rotation of second bevel gear 5402, the rotation of second bevel gear 5402 can drive the rotation of rotating tube 5104, thereby causing rotating tube 5104 and lifting tube 5514 to rotate in opposite directions on the same axis. The rotation of rotating tube 5104 can drive mounting ring 5201 to rotate, the rotation of mounting ring 5201 can drive first ear seat 5202, first rotating shaft 5203, and adapting plate 5211 to rotate, the rotation of rotating tube 5104 can also drive connecting piece 5105 to rotate, the rotation of connecting piece 5105 can drive support block 5106 to rotate through the cooperation of sliding groove and slider, the rotation of support block 5106 can drive crossbar and scraper 5107 to rotate; Simultaneously, when the rotating tube 5501 rotates, it drives the worm gear 5502 to rotate. The rotation of the worm gear 5502 drives the worm wheel 5505 to rotate. The rotation of the worm wheel 5505 drives the first connecting shaft 5504 to rotate. The rotation of the first connecting shaft 5504 drives the rotating plate 5506 to rotate. The rotation of the rotating plate 5506 drives the lead screw 5520 and the adjusting block 5507 to rotate. The rotation of the adjusting block 5507 can push and pull the lifting frame 5511 through the cooperation of the second connecting shaft 5508 and the swing arm 5509, so that the lifting frame 5511 rotates around the third connecting shaft 5512 as the axis. When the lifting frame 5511 is pushed and pulled, it can drive the rotating ring 5516 to move up and down through the fourth connecting shaft 5513. The up and down movement of the rotating ring 5516 can drive the limit ring 5515 to move. The up and down movement of the limit ring 5515 can drive the limit ring 5515 to move. The movement can drive the lifting pipe 5514 to move up and down. The movement of the lifting pipe 5514 can drive the guide bar 5517 to move vertically in the guide groove. The lifting pipe 5514 can drive the fixed frame 5103 to move up and down through the second bearing, thereby causing the first elastic telescopic rod 5102 to move in and out of the frame. The lifting and moving of the fixed frame 5103 can drive the rotating pipe 5104 to move up and down through the first bearing. The lifting and moving of the rotating pipe 5104 can cause the scraper 5107 to move up and down through the cooperation of the connector 5105, the support block 5106 and the crossbar. And through the cooperation of the mounting ring 5201 and the first rotating shaft 5203, the adapting plate 5211 can move up and down, so that the scraper 5107 and the adapting plate 5211 can move up and down and rotate at the same time. When the adapting plate 5211 moves down and enters the inner side of the bend joint, the ball bearing 5302 rolls in contact with the inner wall of the bend joint, causing the adapting plate 5211 to rotate around the first rotating shaft 5203. This causes the top of the adapting plate 5211 to rotate towards the rotating tube 5104, causing the second elastic telescopic rod 5208 to retract. When the adapting plate 5211 rotates around the first rotating shaft 5203, it can push the support block 5106 to move through the cooperation of the second rotating shaft 5204 and the connecting arm 5205. The movement of the support block 5106 can drive the crossbar and scraper 5107 to move, thereby adjusting the position of the scraper 5107 so that the scraper 5107 can adapt to bend joints of different diameters. At this time, since the lifting pipe 5514 and the rotating pipe 5104 rotate in opposite directions, when the lifting pipe 5514 rotates and drives the magnetic block 5309 to the side closer to the storage tank 5301, the sealing ball 5306 squeezes the first spring 5307, causing the lubricating oil to be thrown to the fixed pipe 5303 under the action of centrifugal force. When the magnetic block 5309 rotates to the side away from the storage tank 5301, the first spring 5307 rebounds, driving the sealing ball 5306 to reset and move until the sealing ball 5306... When the fixed tube 5303 is sealed, the lubricating oil in the fixed tube 5303 is transferred to the ball 5302 through the oil suction rope 5305, so that the ball 5302 is fully coated with lubricating oil. As the ball 5302 rolls and the adapting plate 5211 rotates in the bend joint, the lubricating oil is coated on the inner wall of the bend joint, making it easier for the adapting plate 5211 and the scraper 5107 to enter the bend joint and reducing the wear of the adapting plate 5211 and the scraper 5107. When the adapting plate 5211 and scraper 5107 enter the bend joint, the adapting plate 5211 and scraper 5107 rotate and move up and down, thereby using the scraper 5107 to clean the residue near the inner wall of the bend joint end. When the cleaned residue falls into the bend of the bend joint, the air pump 6 is started to deliver gas through the telescopic hose and the jet pipe 7 to the inside of the lifting pipe 5514 and spray it into the bend joint, thereby blowing off the residue at the bend inside the bend joint.
