Description

Technical Field

[0001] This invention relates to the field of automotive pipe processing technology, and in particular to a continuous clamping and feeding device for automotive pipes. Background Technology

[0002] Automotive parts are the basic units that make up the various parts of a vehicle, also called auto components or simply auto parts. They mainly consist of engine parts, transmission parts, braking system parts, etc. Some automotive parts require grinding during processing, and grinding equipment is an essential piece of equipment for this process. In the automotive manufacturing and parts processing field, surface treatment (such as grinding, polishing, and deburring) of pipes (such as exhaust pipes, fuel pipes, hydraulic pipes, etc.) is a key process to ensure their sealing performance, corrosion resistance, and assembly accuracy.

[0003] Utility model patent CN222449534U discloses an automotive parts grinding device, including a feeding mechanism, an intermittent conveying mechanism, a clamping mechanism, a grinding mechanism, a unloading mechanism, and a pipe fitting. The intermittent conveying mechanism includes a shelf, an inlet, an outlet, and an intermittent conveying assembly. The shelf is distributed along the conveying direction, and the inlet and outlet of the shelf are connected to the feeding mechanism and the unloading mechanism, respectively. The intermittent conveying assembly is disposed inside the shelf, and its driving end can drive the pipe fitting to move intermittently along the conveying direction at the top of the shelf, and can convey the pipe fitting to the unloading mechanism. The clamping mechanism is disposed above the shelf, and its clamping end can clamp the pipe fitting at the top of the shelf. The grinding mechanism is disposed on one side of the shelf and distributed along the vertical conveying direction, and its grinding end can grind the pipe fitting clamped by the clamping mechanism.

[0004] The above-mentioned device has the following shortcomings: it feeds materials through an intermittent conveying mechanism, and the positions of the first and second arc-shaped placement ports limit the size of the pipe fittings, making it unable to accommodate multiple specifications of pipe fittings. Furthermore, during the feeding process, the position of the pipe fittings on the first and second arc-shaped placement ports is prone to axial displacement, affecting the subsequent grinding work. Summary of the Invention

[0005] The purpose of this invention is to provide a continuous clamping and feeding device for automotive pipe fittings, which can realize continuous clamping and feeding of pipe fittings, thereby improving grinding efficiency and grinding accuracy.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a continuous clamping and feeding device for automotive pipe fittings, comprising a base, on which a support frame, a conveyor frame, and a grinding frame are sequentially fixed; an arc-shaped feeding frame is fixed on the support frame, the arc-shaped feeding frame having a feeding channel; a feeding cylinder located at the bottom end of the arc-shaped feeding frame is rotatably connected to the support frame; the feeding cylinder has a feeding port communicating with the feeding channel; a storage rack located on the side of the feeding cylinder away from the arc-shaped feeding frame is fixed to the support frame; and a sliding support frame is mounted on the conveyor frame. The device includes a movable platform with mirror-slidable movable frames on both sides. Clamping components, located on either side of the storage rack, are mirror-slidably arranged on the inner sides of the movable frames. A first support slides on the grinding rack, and a second support slides on the first support. A grinding wheel is mounted on the second support. A feeding component that drives the feeding cylinder to rotate is mounted on the support frame. A conveying frame that drives the movable platform to move from the support frame towards the grinding rack is mounted on the conveyor frame. An adjustment component that drives the mirror-slidable movable frames on both sides is mounted on the movable platform.

[0007] By adopting the above technical solution, multiple pipe fittings to be ground are stacked side by side on the arc-shaped feeding rack. Initially, the feeding port on the feeding cylinder is directly opposite the feeding channel. The pipe fitting at the bottom falls into the feeding cylinder under its own weight through the feeding port. Subsequently, the feeding assembly drives the feeding cylinder to rotate, sending the pipe fittings in the feeding cylinder to the storage rack. During the rotation of the feeding cylinder towards the storage rack, the cylinder wall blocks the pipe fittings in the feeding channel, preventing them from falling. When the feeding cylinder rotates back to the point where the feeding port is directly opposite the feeding channel again, the pipe fittings in the feeding channel fall back into the feeding cylinder, achieving... Automatic feeding of pipe fittings improves overall feeding efficiency. The adjusting component drives the two sides of the moving frame on the moving platform to move in a mirror image, so that the clamping component on the moving frame clamps the pipe fitting. The feeding component drives the moving platform to move from the support frame to the grinding frame, so that the clamped pipe fitting is moved from above the storage rack to the grinding frame to be ground by the grinding wheel. This can avoid the displacement of the pipe fitting during feeding, improve the subsequent grinding accuracy, and at the same time, it can be used for multiple specifications of pipe fittings, meet the continuous clamping and feeding of multiple specifications of pipe fittings, reduce intermittent waiting time, and improve the overall grinding production efficiency.

[0008] A further configuration of the present invention is as follows: the feeding assembly includes a first screw rotatably connected to the conveyor frame and a first guide rod parallel to the first screw fixedly connected to the conveyor frame; a first motor for driving the first screw to rotate is mounted on the conveyor frame; and a fixing block threadedly connected to the first screw and a slider slidably connected to the first guide rod are fixed at the bottom of the moving table.

[0009] By adopting the above technical solution, the first motor is started, which drives the first screw to rotate. The first screw then drives the moving table to slide on the conveyor frame, thereby realizing the feeding and resetting of the moving table. The pipes clamped on the storage rack are moved from the storage rack to the area under the grinding wheel for grinding.

[0010] A further configuration of the present invention is as follows: a drive rack is fixed at the bottom of the moving platform; the feeding assembly includes a first rotating shaft rotatably connected to the conveyor frame; a first gear meshing with the drive rack is fixed at one end of the first rotating shaft; a second rotating shaft rotatably connected to the support frame is fixed on the side of the feeding cylinder; and a first belt is sleeved between the second rotating shaft and the first rotating shaft.

[0011] By adopting the above technical solution, when the moving table moves towards the grinding frame, the drive rack meshes with the first gear, driving the first gear and the first rotating shaft to rotate. The first rotating shaft drives the second rotating shaft and the feeding cylinder to rotate through the first belt. The rotation of the feeding cylinder feeds the pipes inside the cylinder into the storage rack. At the same time, the cylinder wall of the feeding cylinder blocks the pipes in the feeding channel, preventing the pipes in the feeding channel from falling. When the moving table moves towards the storage rack, the drive rack drives the feeding cylinder to rotate in the opposite direction, so that the feeding cylinder rotates back to face the feeding channel again. The pipes in the feeding channel fall back into the feeding cylinder. At the same time, the clamping assembly clamps the pipes that have fallen into the storage rack and feeds them, realizing continuous feeding and clamping of pipes, reducing the waiting time for pipe feeding, and improving the overall grinding production efficiency.

[0012] A further configuration of the present invention is as follows: the storage rack includes a guide plate that is inclinedly fixed to the support frame, a flap is hinged to the side of the guide plate away from the feeding cylinder, a torsion spring is installed between the flap and the guide plate, and a conveyor platform located below the storage rack is provided on the base.

[0013] By adopting the above technical solution, after the two sets of clamping components on both sides of the storage rack clamp the two ends of the pipe, the feeding component drives the moving table to move on the conveyor frame to feed the pipe. When the clamped pipe passes the flip plate, it pushes the flip plate to flip relative to the guide plate to avoid obstructing the movement of the pipe. After the pipe passes the flip plate, the flip plate rotates under the action of the torsion spring to form a groove between it and the guide plate to allow the pipe to fall in. The guide plate guides the pipe that falls out of the feeding cylinder again into the groove, waiting for the next clamping and feeding operation. When the clamped pipe is polished by the grinding wheel, the feeding component drives the moving table to reset and move close to the storage rack. At the same time, the clamping component releases the pipe, and the adjusting component drives the two moving frames on both sides to move in opposite directions to move away from each other and release the pipe. The polished pipe falls onto the conveyor table and is removed.

[0014] A further configuration of the present invention is as follows: the adjustment assembly includes a second screw with reverse threads at both ends rotatably connected to the movable platform, the bottoms of the two movable frames on both sides being threaded to the two ends of the second screw, and a second motor for driving the second screw to rotate is mounted on the movable platform.

[0015] By adopting the above technical solution, the second motor is started, which drives the second screw to rotate. The second screw then drives the two moving frames on both sides to move in opposite directions on the moving platform to move closer to the moving platform and cooperate with the clamping components to clamp the pipe to achieve feeding and grinding, or to move in opposite directions away from the moving platform to cooperate with the clamping components to release the pipe and achieve automatic unloading.

[0016] A further configuration of the present invention is as follows: the clamping assembly includes a movable plate rotatably connected to the movable frame, an adjusting plate rotatably connected to the movable plate, a through hole in the middle of the adjusting plate, a connecting plate fixed to the movable plate at the through hole, a fixing plate fixed to the end of the connecting plate away from the movable plate, the adjusting plate being located between the fixing plate and the movable plate, an adjusting groove surrounding the through hole on the adjusting plate, the adjusting groove being arc-shaped, one end of the adjusting groove being close to the through hole and the other end being away from the through hole, a first limiting groove on the fixing plate, a limiting plate slidably connected within the first limiting groove, an adjusting rod slidably sliding within the adjusting groove fixed to the side of the limiting plate close to the adjusting plate, an inner support plate fixed to the side of the limiting plate away from the adjusting plate, a clamping motor fixedly mounted on the movable plate, a gear ring fixedly fixed to the outside of the adjusting plate, and a second gear meshing with the gear ring fixed to the output end of the clamping motor.

[0017] By adopting the above technical solution, the two movable frames move closer to each other on the movable platform, and the inner support plates of the clamping components on both sides are respectively sent into the inside of both ends of the pipe. The clamping motor is started, and the output end of the clamping motor drives the second gear to rotate, which in turn drives the gear ring and the adjusting plate to rotate. The rotation of the adjusting plate pushes the limiting plate to move away from the through hole in the first limiting groove through the adjusting groove and the adjusting rod. Then, multiple inner support plates located on the same fixed plate move synchronously away from the through hole until the inner support plates abut against the inner wall of the pipe, so that the pipe and the movable plate are relatively fixed. It is suitable for pipes of various diameters. When the movable platform and the movable frame move, they drive the clamped pipe to move synchronously for feeding, avoiding displacement or offset during pipe feeding and processing, and avoiding affecting the grinding work and processing accuracy.

[0018] A further feature of the present invention is that: each of the movable plates on both sides is fixed with a third rotating shaft rotatably connected to the movable frame; a telescopic rod is rotatably connected between the two movable frames on both sides; an adjusting motor for driving the telescopic rod to rotate is installed on one of the movable frames; and a second belt is sleeved between each end of the telescopic rod and one of the two third rotating shafts.

[0019] By adopting the above technical solution, when the two moving frames move closer or further away, the telescopic rod extends or shortens as a whole. When the grinding wheel grinds the pipe, the adjustment motor is started, causing the output end of the adjustment motor to drive the telescopic rod to rotate as a whole. Then, the two ends of the telescopic rod drive the third rotating shaft to rotate through the second belt. In turn, the third rotating shaft on both sides, the movable plate, and the pipe clamped on the movable plate rotate synchronously, adjusting the grinding position of the pipe so that the pipe can be ground from all directions, thus improving the grinding efficiency.

[0020] A further configuration of the present invention is as follows: the telescopic rod includes a sleeve rod rotatably connected to one of the movable frames, and a slide rod rotatably connected to the other movable frame, the end of which slides within the sleeve rod; the inner wall of the sleeve rod is provided with a groove along its axial direction, and the outer wall of the slide rod is fixed with a slide bar that slides within the groove along its axial direction.

[0021] By adopting the above technical solution, when the two moving frames move, the slide rod slides in the sleeve rod to adjust the overall length of the telescopic rod. When the adjusting motor is installed on one of the moving frames and drives the slide rod or sleeve rod to rotate, the slide rod and sleeve rod can be driven to rotate synchronously through the cooperation of the slide bar and the slide groove, and then the telescopic rod rotates as a whole, so that the two ends of the telescopic rod drive the third rotating shaft and the pipe to rotate through the second belt.

[0022] A further configuration of the present invention includes: a horizontally arranged third screw rotatably connected to the grinding frame; a first moving block threadedly connected to the third screw and slidably connected to the grinding frame fixed at the bottom of the first bracket; a third motor driving the third screw to rotate mounted on the grinding frame; a vertically arranged fourth screw rotatably connected to the first bracket; a second moving block threadedly connected to the fourth screw and slidably connected to the first bracket fixed on one side of the second bracket; a fourth motor driving the fourth screw to rotate mounted on the first bracket; a grinding wheel rotatably connected to the second bracket; and a grinding motor driving the grinding wheel to rotate mounted on the second bracket.

[0023] By adopting the above technical solution, when performing the grinding work, the third motor is started, which drives the third screw to rotate, thereby causing the first bracket to move horizontally on the grinding frame and adjust the horizontal position of the grinding wheel; the fourth motor is started, which drives the fourth screw to rotate, thereby causing the second bracket to move vertically on the first bracket and adjust the height of the grinding wheel, so as to realize the comprehensive grinding work on the outer surface of the pipe fitting.

[0024] A further configuration of the present invention is as follows: a fixed frame is fixed on the side of the conveyor frame away from the arc-shaped feeding frame, a grinding cover is fixed on the fixed frame, slots are opened on both sides of the grinding cover, and a feed inlet is opened on the side facing the feeding cylinder, a second limiting groove is provided at the bottom of the grinding cover, a baffle that covers the feed inlet slides in the second limiting groove, a fifth screw is rotatably connected to the fixed frame, the baffle has an inner cavity, the inner cavity wall has an internal thread that mates with the fifth screw, a first bevel tooth is fixed at the bottom end of the fifth screw, a fourth rotating shaft and a fifth rotating shaft are rotatably connected to the conveyor frame, a second bevel tooth that meshes with the first bevel tooth is fixed on the fourth rotating shaft, a third gear that meshes with the drive rack is fixed on the fifth rotating shaft, a third belt is sleeved between the fourth rotating shaft and the fifth rotating shaft, and a negative pressure pipe is connected to the grinding cover.

[0025] By adopting the above technical solution, the groove on the grinding cover is used for the passage of the movable plate. When the moving table moves towards the grinding frame and the pipe is moved into the grinding cover, the drive rack meshes with the third gear, causing the third gear to rotate. This, in turn, causes the fifth rotating shaft to rotate. The third belt drives the fourth rotating shaft to rotate synchronously. The rotation of the fourth rotating shaft drives the first bevel gear to rotate through the second bevel gear. This, in turn, causes the fifth screw to rotate, causing the baffle connected to it to slide up in the second limiting groove to close the feed port. This allows the pipe to be ground inside the grinding cover. The grinding cover blocks the debris generated during grinding, preventing contamination of the processing site. When the grinding work is finished and the moving table moves back to the storage rack to reset, the drive rack drives the third gear to reverse. This, in turn, causes the fifth rotating shaft, the fourth rotating shaft, the second bevel gear, the first bevel gear, and the fifth screw to reverse. The baffle slides down in the second limiting groove to open the feed port. The moving table continues to move, causing the pipe to be moved out of the grinding cover.

[0026] The beneficial effects of this invention are:

[0027] 1. Multiple pipe fittings to be ground are stacked side by side on the arc-shaped feeding rack. The feeding assembly drives the feeding cylinder to rotate to realize automatic feeding of the pipe fittings and improve the overall feeding efficiency.

[0028] 2. The adjustment component drives the moving frame to move, so that the clamping component on the moving frame clamps the pipe fitting. The feeding component drives the moving table to move from the support frame to the grinding frame, so that the clamped pipe fitting is moved from above the storage rack to the grinding frame to be ground by the grinding wheel. This satisfies the continuous clamping and feeding of multi-specification pipe fittings, reduces intermittent waiting time, and improves the overall grinding production efficiency.

[0029] 3. The clamping assembly can clamp pipes of various diameters, so that the moving table and moving frame can move synchronously to feed the clamped pipes when they move, avoiding displacement or offset during pipe feeding and processing, and avoiding affecting the grinding work and processing accuracy.

[0030] 4. Adjust the motor output to drive the telescopic rod to rotate as a whole. Then, the two ends of the telescopic rod drive the third rotating shaft to rotate through the second belt. Then, the third rotating shaft on both sides, the movable plate, and the pipe clamped on the movable plate rotate synchronously. Adjust the grinding position of the pipe so that the pipe can be ground from all directions, thus improving the grinding efficiency.

[0031] 5. When performing grinding, start the third motor, which drives the third screw to rotate, thereby moving the first support horizontally on the grinding frame to adjust the horizontal position of the grinding wheel; start the fourth motor, which drives the fourth screw to rotate, thereby moving the second support vertically on the first support to adjust the height of the grinding wheel, thus achieving comprehensive grinding of the outer surface of the pipe fitting.

[0032] 6. When the moving table moves towards the grinding frame and the pipe is moved into the grinding hood, the drive rack meshes with the third gear, causing the third gear to rotate. This, in turn, causes the fifth shaft, the fourth shaft, the second bevel gear, the first bevel gear, and the fifth screw to rotate, which in turn causes the baffle to slide up in the second limiting groove to close the feed port. This allows the pipe to be ground inside the grinding hood. The grinding hood blocks the debris generated during grinding, preventing contamination of the processing area.

Detailed Implementation

[0043] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0044] Example 1: A continuous clamping and feeding device for automotive pipe fittings, such as... Figure 1-8As shown, the system includes a base 1, on which a support frame 2, a conveyor frame 3, and a grinding frame 4 are sequentially fixed. An arc-shaped feeding frame 5 is fixed to the support frame 2, and the arc-shaped feeding frame 5 has a feeding channel 6. A feeding cylinder 7 located at the bottom end of the arc-shaped feeding frame 5 is rotatably connected to the support frame 2. The feeding cylinder 7 has a feeding port 8 communicating with the feeding channel 6. A storage rack 9 is fixed to the support frame 2 on the side of the feeding cylinder 7 away from the arc-shaped feeding frame 5. A movable platform 10 slides on the conveyor frame 3, and movable frames 11 slide mirror-on both sides of the movable platform 10. The inner side of the movable frame 11 is mirror-equipped with clamping components 12 located on both sides of the storage rack 9. A first support 13 slides on the grinding rack 4, a second support 14 slides on the first support 13, a grinding wheel 15 is installed on the second support 14, a feeding component 16 that drives the feeding cylinder 7 to rotate is installed on the support frame 2, a feeding component 17 that drives the movable table 10 to move from the support frame 2 to the grinding rack 4 is installed on the conveying frame 3, and an adjustment component 18 that drives the two movable frames 11 to slide mirror-equipped on the movable table 10.

[0045] Multiple pipe fittings to be ground are stacked side-by-side on the arc-shaped feeding rack 5. Initially, the feeding port 8 on the feeding cylinder 7 is aligned with the feeding channel 6. The pipe fitting at the bottom falls into the feeding cylinder 7 under its own weight through the feeding port 8. Subsequently, the feeding assembly 16 drives the feeding cylinder 7 to rotate, feeding the pipe fittings in the feeding cylinder 7 into the storage rack 9. During the rotation of the feeding cylinder 7 towards the storage rack 9, the cylinder wall of the feeding cylinder 7 blocks the pipe fittings in the feeding channel 6, preventing them from falling. When the feeding cylinder 7 rotates back to the feeding port 8 being aligned with the feeding channel 6 again, the pipe fittings in the feeding channel 6 fall back into the feeding cylinder 7, realizing automatic feeding of the pipe fittings. The material feeding component 17 drives the moving table 10 to move the two moving frames 11 on both sides in a mirror manner, so that the clamping component 12 on the moving frame 11 clamps the pipe. The feeding component 17 drives the moving table 10 to move from the support frame 2 to the grinding frame 4, so that the clamped pipe is moved from above the storage rack 9 to the grinding frame 4 and ground by the grinding wheel 15. This can avoid the displacement of the pipe during the feeding process, improve the subsequent grinding accuracy, and at the same time, it can be used for multiple specifications of pipes, meet the continuous clamping and feeding of multiple specifications of pipes, reduce the intermittent waiting time, and improve the overall grinding production efficiency.

[0046] Furthermore, the feeding assembly 17 includes a first screw 171 rotatably connected to the conveyor frame 3 and a first guide rod 172 parallel to the first screw 171 and fixedly connected to the conveyor frame 3. A first motor 173 that drives the first screw 171 to rotate is installed on the conveyor frame 3. A fixing block 174 threadedly connected to the first screw 171 and a slider slidably connected to the first guide rod 172 are fixed at the bottom of the moving table 10.

[0047] By starting the first motor 173, the first motor 173 drives the first screw 171 to rotate, and then the first screw 171 drives the moving table 10 to slide on the conveyor frame 3, so as to realize the feeding and resetting of the moving table 10, and move the pipes clamped on the storage rack 9 from the storage rack 9 to the ground wheel 15 for grinding.

[0048] Furthermore, a drive rack 19 is fixed at the bottom of the moving table 10, and the feeding assembly 16 includes a first rotating shaft 161 rotatably connected to the conveyor frame 3. A first gear 162 that meshes with the drive rack 19 is fixed at one end of the first rotating shaft 161. A second rotating shaft 163 rotatably connected to the support frame 2 is fixed on the side of the feeding cylinder 7. Both the second rotating shaft 163 and the first rotating shaft 161 are coaxially fixed with pulleys. A first belt 164 is sleeved between the pulley on the first rotating shaft 161 and the pulley on the second rotating shaft 163.

[0049] When the moving table 10 moves toward the grinding frame 4, the drive rack 19 meshes with the first gear 162, driving the first gear 162 and the first rotating shaft 161 to rotate. The first rotating shaft 161 drives the second rotating shaft 163 and the feeding cylinder 7 to rotate through the first belt 164. The rotation of the feeding cylinder 7 feeds the pipes inside the cylinder into the storage rack 9. At the same time, the cylinder wall of the feeding cylinder 7 blocks the pipes in the feeding channel 6, preventing the pipes in the feeding channel 6 from falling. When the moving table 10 moves toward the storage rack 9, the drive rack 19 drives the feeding cylinder 7 to rotate in the opposite direction, so that the feeding cylinder 7 rotates back to the feeding port 8 and faces the feeding channel 6 again. The pipes in the feeding channel 6 fall back into the feeding cylinder 7. At the same time, the clamping assembly 12 clamps the pipes that have fallen into the storage rack 9 and feeds them, realizing continuous feeding and continuous clamping of pipes, reducing the waiting time for pipe feeding.

[0050] Furthermore, the storage rack 9 includes a guide plate 91 that is tilted and fixed to the support frame 2. A flap 92 is hinged to the side of the guide plate 91 away from the feeding cylinder 7. A torsion spring is installed between the flap 92 and the guide plate 91. A conveyor table 20 located below the storage rack 9 is provided on the base 1.

[0051] After the two sets of clamping components 12 located on both sides of the storage rack 9 clamp the two ends of the pipe, the feeding component 17 drives the moving table 10 to move and feed on the conveyor frame 3. When the clamped pipe passes the flip plate 92, it pushes the flip plate 92 to flip relative to the guide plate 91 to avoid obstructing the movement of the pipe. After the pipe passes the flip plate 92, the flip plate 92 rotates under the action of the torsion spring to form a groove between it and the guide plate 91 to allow the pipe to fall in. The guide plate 91 guides the pipe that falls out of the feeding cylinder 7 into the groove, waiting for the next clamping and feeding operation. When the clamped pipe is polished by the grinding wheel 15, the feeding component 17 drives the moving table 10 to reset and move closer to the storage rack 9. During this process, the clamping component 12 releases the pipe, and at the same time, the adjusting component 18 drives the two moving frames 11 to move in opposite directions and move away from each other to release the pipe. The polished pipe falls onto the conveyor table 20 and is removed.

[0052] Furthermore, the adjustment assembly 18 includes a second screw 181 rotatably connected to the two ends of the movable platform 10 with reverse threads, the bottom of the two movable frames 11 being threaded to the two ends of the second screw 181 respectively, and a second motor 182 for driving the second screw 181 to rotate is installed on the movable platform 10.

[0053] By starting the second motor 182, the second motor 182 drives the second screw 181 to rotate, and then the second screw 181 drives the two side moving frames 11 to move in the opposite direction on the moving table 10 to approach and cooperate with the clamping assembly 12 to clamp the pipe to achieve feeding and grinding, or to move in the opposite direction away from the clamping assembly 12 to release the pipe to achieve automatic unloading.

[0054] Furthermore, the clamping assembly 12 includes a movable plate 1201 rotatably connected to the movable frame 11. An adjusting plate 1202 is rotatably connected to the movable plate 1201. The adjusting plate 1202 has a through hole 1203 in the middle. A connecting plate 1204 located at the through hole 1203 is fixed to the movable plate 1201. A fixing plate 1205 is fixed to one end of the connecting plate 1204 away from the movable plate 1201. The adjusting plate 1202 is located between the fixing plate 1205 and the movable plate 1201. The adjusting plate 1202 has an adjusting groove 1206 surrounding the through hole 1203. The adjusting groove 1206 is arc-shaped. The distance between one end of the adjusting groove 1206 and the axis of the adjusting plate 1202 is equal to the distance between the other end of the adjusting groove 1206 and the axis of the adjusting plate 1202. The distance between the axes of the plate 1202 gradually increases. One end of the adjusting groove 1206 is close to the through hole 1203 and the other end is away from the through hole 1203. The fixed plate 1205 is provided with a first limiting groove 1207. A limiting plate 1208 is slidably connected in the first limiting groove 1207. An adjusting rod 1209 that slides in the adjusting groove 1206 is fixed on the side of the limiting plate 1208 close to the adjusting plate 1202. An inner support plate 1210 is fixed on the side of the limiting plate 1208 away from the adjusting plate 1202. A clamping motor 1211 is fixedly installed on the movable plate 1201. A gear ring 1212 is fixed outside the adjusting plate 1202. A second gear 1213 that meshes with the gear ring 1212 is fixed at the output end of the clamping motor 1211.

[0055] The second motor 182 drives the second screw 181 to rotate, causing the two movable frames 11 to move closer to each other on the movable platform 10. This moves the inner support plates 1210 of the two clamping assemblies 12 into the two ends of the pipe fitting. The clamping motor 1211 is then started, and its output drives the second gear 1213 to rotate, which in turn drives the gear ring 1212 and the adjusting plate 1202 to rotate. The rotation of the adjusting plate 1202 pushes the limiting plate 1208 to move away from the through hole 1203 in the first limiting groove 1207 through the adjusting groove 1206 and the adjusting rod 1209. Consequently, multiple inner support plates 1210 located on the same fixed plate 1205 move synchronously away from the through hole 1203 until the inner support plates 1210 abut against the inner wall of the pipe fitting, thus fixing the pipe fitting relative to the movable plate 1201. This method is suitable for pipes of various diameters. The material is fed synchronously by the moving table 10 and the moving frame 11, which drives the clamped pipe to move synchronously during the feeding and processing of the pipe, thus avoiding displacement or offset during the grinding work and processing accuracy. After the pipe is ground, the moving frame 11 returns and moves the pipe to the top of the conveyor table 20. The output end of the clamping motor 1211 drives the second gear 1213 to rotate in the opposite direction, which in turn drives the gear ring 1212 and the adjusting plate 1202 to rotate in the opposite direction. The reverse rotation of the adjusting plate 1202 pushes the limiting plate 1208 to move towards the through hole 1203 in the first limiting groove 1207 through the adjusting groove 1206 and the adjusting rod 1209. At the same time, the second motor 182 drives the two moving frames 11 to move away from each other on the moving table 10, thereby releasing the pipe. The ground pipe falls onto the conveyor table 20 and is removed.

[0056] Furthermore, both movable plates 1201 on both sides are fixed with a third rotating shaft 21 rotatably connected to the movable frame 11. A telescopic rod 22 is rotatably connected between the two movable frames 11. An adjusting motor 23 for driving the telescopic rod 22 to rotate is installed on one movable frame 11. Both ends of the telescopic rod 22 and the third rotating shaft 21 are fixed with pulleys. The pulleys at both ends of the telescopic rod 22 are respectively connected to the pulleys on the two third rotating shafts 21 with a second belt 24.

[0057] When the two movable frames 11 move closer or further away, the telescopic rod 22 extends or shortens as a whole. When the grinding wheel 15 grinds the pipe, the adjustment motor 23 is started, causing the output end of the adjustment motor 23 to drive the telescopic rod 22 to rotate as a whole. Then, the two ends of the telescopic rod 22 drive the third rotating shaft 21 to rotate through the second belt 24. Then, the third rotating shaft 21 on both sides, the movable plate 1201 and the pipe clamped on the movable plate 1201 rotate synchronously, adjusting the grinding position of the pipe so that the pipe can be ground from all directions.

[0058] Furthermore, the telescopic rod 22 includes a sleeve rod 221 rotatably connected to one of the movable frames 11, and a slide rod 222 rotatably connected to the other movable frame 11 with its end sliding inside the sleeve rod 221. The inner wall of the sleeve rod 221 is provided with a slide groove along its axial direction, and the outer wall of the slide rod 222 is fixed with a slide bar 223 that slides in the slide groove along its axial direction.

[0059] When the two movable frames 11 move, the slide rod 222 slides within the sleeve rod 221 to adjust the overall length of the telescopic rod 22. When the adjusting motor 23 is installed on one of the movable frames 11 and drives the slide rod 222 or the sleeve rod 221 to rotate, the slide bar 223 and the slide groove can drive the slide rod 222 and the sleeve rod 221 to rotate synchronously, thereby causing the telescopic rod 22 to rotate as a whole, so that the two ends of the telescopic rod 22 drive the third rotating shaft 21 and the pipe to rotate through the second belt 24.

[0060] Furthermore, a horizontally arranged third screw 25 is rotatably connected to the grinding frame 4, a first moving block 26 threaded to the third screw 25 and slidably connected to the grinding frame 4 is fixed at the bottom of the first bracket 13, a third motor 27 for driving the third screw 25 to rotate is installed on the grinding frame 4, a vertically arranged fourth screw 28 is rotatably connected to the first bracket 13, a second moving block 29 threaded to the fourth screw 28 and slidably connected to the first bracket 13 is fixed on one side of the second bracket 14, a fourth motor 30 for driving the fourth screw 28 to rotate is installed on the first bracket 13, a grinding wheel 15 is rotatably connected to the second bracket 14, and a grinding motor 31 for driving the grinding wheel 15 to rotate is installed on the second bracket 14;

[0061] When performing the grinding work, the third motor 27 is started, which drives the third screw 25 to rotate, thereby causing the first bracket 13 to move horizontally on the grinding frame 4 and adjusting the horizontal position of the grinding wheel 15; the fourth motor 30 is started, which drives the fourth screw 28 to rotate, thereby causing the second bracket 14 to move vertically on the first bracket 13 and adjusting the height of the grinding wheel 15, so as to achieve the comprehensive grinding work on the outer surface of the pipe fitting.

[0062] Furthermore, a fixing frame 32 is fixed on the side of the conveyor frame 3 away from the arc-shaped feeding frame 5. A grinding cover 33 is fixed on the fixing frame 32. The grinding cover 33 has slots 34 on both sides and a feed inlet 35 on the side facing the feeding cylinder 7. A second limiting groove 36 is provided at the bottom of the grinding cover 33. A baffle 37 that covers the feed inlet 35 slides in the second limiting groove 36. A fifth screw 38 is rotatably connected to the fixing frame 32. The baffle 37 has an inner cavity, and the inner cavity wall is provided with a surface that is flush with the fifth screw 38. The fifth screw 38 has a mating internal thread, and the bottom end of the fifth screw 38 is fixed with a first bevel tooth 39. The fourth rotating shaft 40 and the fifth rotating shaft 41 are rotatably connected on the conveyor frame 3. The fourth rotating shaft 40 is fixed with a second bevel tooth 42 that meshes with the first bevel tooth 39. The fifth rotating shaft 41 is fixed with a third gear 43 that meshes with the drive rack 19. Both the fourth rotating shaft 40 and the fifth rotating shaft 41 are fixedly connected with pulleys. A third belt 44 is sleeved between the pulley on the fourth rotating shaft 40 and the pulley on the fifth rotating shaft 41.

[0063] The groove 34 on the grinding cover 33 is used for the passage of the movable plate 1201. When the moving table 10 moves towards the grinding frame 4 and the pipe is moved into the grinding cover 33, the drive rack 19 meshes with the third gear 43, causing the third gear 43 to rotate. This, in turn, causes the fifth rotating shaft 41 to rotate, which in turn causes the fourth rotating shaft 40 to rotate synchronously via the third belt 44. The rotation of the fourth rotating shaft 40, through the second bevel gear 42, causes the first bevel gear 39 to rotate. This, in turn, causes the fifth screw 38 to rotate, causing the threaded baffle 37 to slide and rise within the second limiting groove 36 to close the feed. The inlet 35 allows the pipe to be ground inside the grinding cover 33. The grinding cover 33 blocks the debris generated during grinding, preventing contamination of the processing area. When the grinding is finished, the moving table 10 moves back to the storage rack 9 to reset. The drive rack 19 drives the third gear 43 to reverse, which in turn causes the fifth rotating shaft 41, the fourth rotating shaft 40, the second bevel gear 42, the first bevel gear 39, and the fifth screw 38 to reverse. The baffle 37 slides down in the second limiting groove 36 to open the feed inlet 35. The moving table 10 continues to move, causing the pipe to be moved out of the grinding cover 33.
