TECHNICAL FIELD

[0001] The utility model relates to the technical field of pipe body processing, and specifically relates to an automatic pipe cutting and assembling machine. BACKGROUND

[0002] The hose connection is a connection mode for transmitting fluid or sometimes transmitting power in machinery, equipment or pipeline system through flexible pipeline and its accessories, which solves the problems difficult to handle by rigid connection such as vibration, displacement and installation error, and is used in many fields such as motorcycle brake systems. When the hose is installed, a joint accessory is usually arranged at both ends of the pipeline for connection. The hose needs to be pulled out to the required length for cutting during processing, and then the cutting surface is polished and chamfered for convenient insertion of the joint. Then the joint is inserted and then the joint is riveted to compress it tightly. The existing processing is processed by manual operation. A production line is usually arranged to allow workers to cut in batches, then take the cut hose to the next station for polishing and chamfering, and then install the joint at the next station for riveting. It is very troublesome, wastes manpower and has low efficiency. SUMMARY

[0003] In order to overcome the shortcomings of the prior art, the utility model provides an automatic pipe cutting and assembling machine which can automatically cut and assemble the pipe body.

[0004] In order to achieve the above object, the utility model provides the following technical scheme: an automatic pipe cutting and assembling machine, comprising a rack, a cutting device, a chamfering device, an assembling device and a riveting device, the cutting device comprising a feeding mechanism, a cutting mechanism, a discharging mechanism and a conveying mechanism, the feeding mechanism being connected with the cutting mechanism, the discharging mechanism being connected with the cutting mechanism and the conveying mechanism, the chamfering device, the assembling device and the riveting device each being provided with two and being arranged on both sides of the conveying mechanism.

[0005] In this way, when the machine is started, the feeding mechanism moves the pipe body raw material into the cutting mechanism for cutting. After cutting, the discharging mechanism moves the pipe body of the determined length to the conveying mechanism, which transports it to the chamfering device position for edge polishing and chamfering treatment of both ends of the pipe body. After chamfering both ends of the pipe body, the conveying mechanism transports the pipe body to the assembling device position to insert the joint at both ends, and then transports it to the riveting device position to rivet the joint. The joint is fastened to the connection position of the pipe body. In this way, the cutting and assembling connection process of the pipe body is completed. Then the conveying mechanism sends the assembled pipe body out of the rack. The whole process only needs to start the machine, and the pipe body processing can be automatically completed without manual operation, which is more efficient.

[0006] Further, the cutting mechanism comprises a cutting disc and a supporting rod, the cutting disc is arranged towards the supporting rod, the blanking mechanism comprises a first driving member, the first driving member controls the supporting rod to rotate reciprocatingly towards the direction of the conveying mechanism.

[0007] In this way, the feeding mechanism conveys the pipe body to the supporting rod, then the cutting disc is inserted from the side of the supporting rod after being rotated by the motor and being pushed by a push rod or the like, or the cutting disc is inserted into a cutting groove arranged on the supporting rod, so that the pipe body on the supporting rod can be cut, and the pipe body with the required length is left on the supporting rod after the cutting is completed, at this time, the first driving member controls the supporting rod to rotate towards the conveying mechanism, so that the pipe body on the supporting rod is placed on the conveying mechanism, and then the supporting rod is rotated back to the original position for conveying the pipe body and cutting the pipe body again, and a cover can be arranged on the cutting disc, so that the cutting disc is safer and manual operation is not needed, and the efficiency is high.

[0008] Further, the blanking mechanism further comprises a first driving rod, the first driving rod is rotationally connected with the rack, the supporting rod is connected with the first driving rod, the first driving member is a motor, and the first driving rod is connected with an output shaft of the first driving member.

[0009] In this way, the rod-shaped first driving rod is selected as the main rotating member, so that the supporting rod can be freely arranged in a required shape to conveniently place the pipe body and cut the pipe body.

[0010] Further, the conveying mechanism comprises a second push-pull machine, a sliding rod and a plurality of clamping assemblies, the plurality of clamping assemblies are connected with the sliding rod, and the second push-pull machine controls the sliding rod to move reciprocatingly in the direction away from the cutting mechanism.

[0011] In this way, the clamping assemblies can clamp the pipe body falling from the blanking mechanism, then the second push-pull machine operates to drive the sliding rod to move the pipe body to the next station, at this time, other components on the station can fix the pipe body to process the pipe body, at this time, the clamping assemblies can release the pipe body, and then the second push-pull machine drives the sliding rod to be pulled back to clamp the next falling pipe body, and the pipe body processed by other stations is also clamped by other clamping assemblies on the sliding rod after being released by the station, so that the pipe body can be continuously conveyed to the next position, the conveying mechanism needs smaller moving space, and the space utilization rate is higher.

[0012] Further, the chamfering device comprises a third push-pull machine, a fifth driving member and a chamfering disc, the fifth driving member controls the chamfering disc to rotate, and the third push-pull machine controls the chamfering disc to move reciprocatingly relative to the pipe body.

[0013] Thus, when the pipe body is moved by the conveying mechanism to the chamfering device, the fifth driving member will start to drive the chamfering disc to rotate, and then the third push-pull machine will push the chamfering disc to move towards the pipe body, and when the chamfering disc contacts the pipe body, the end of the pipe body will be chamfered, and after the chamfering is completed, the third push-pull machine will pull the chamfering disc back, and then the fifth driving member will stop working. The third push-pull machine can directly control the movement of the chamfering disc towards the pipe body, or control the movement of the pipe body towards the chamfering disc. The relative movement in other aspects of the application can be in this form.

[0014] Further, the chamfering device further comprises a sixth driving member and a connecting plate, the chamfering disc is provided with two, the two chamfering discs are connected with the connecting plate, and the sixth driving member controls the rotation of the connecting plate at a position between the two chamfering discs.

[0015] Thus, when polishing, the sixth driving member will drive the connecting plate to rotate, and the two chamfering discs on the connecting plate will be rotated at the same time, and each of the two chamfering discs is driven by the fifth driving member. In this way, the pipe body can be chamfered more quickly, and the residues after polishing are more easily dropped from the gap between the two chamfering discs and are not easily left on the chamfering disc.

[0016] Further, the assembling device comprises a vibrating disc, a conveying belt and a mechanical hand, the conveying belt is connected with the vibrating disc, and the mechanical hand is located on the side of the conveying belt facing the conveying mechanism.

[0017] Thus, a large number of joints are placed in the vibrating disc, and the joints are moved to the conveying belt during the vibration process. When the joints reach the position of the pipe body, the mechanical hand will operate to clamp the joints and insert the joints into the end position of the pipe body, without manual operation.

[0018] Further, the riveting device comprises a riveting frame, a ninth driving member, a sixth push-pull machine and a plurality of riveting blocks, the riveting frame is provided with a riveting hole, the plurality of riveting blocks are located in the riveting hole, the ninth driving member controls the reciprocating movement of the riveting blocks towards the center of the riveting hole, and the sixth push-pull machine controls the reciprocating relative movement of the riveting frame towards the pipe body.

[0019] Thus, when riveting, the sixth push-pull machine will control the pipe body to enter the riveting hole in the riveting frame, and after entering, the ninth driving member drives the plurality of riveting blocks to move towards the joint on the pipe body until the joint is clamped and riveted, and then the riveting blocks retreat, and then the sixth push-pull machine extracts the pipe body. At this time, the joint will be deformed and fixed on the end of the pipe body, and then it can continue to be conveyed to the rear, without manual operation throughout the process, and the efficiency is higher.

[0020] Furthermore, the top of the frame is provided with a fixed platform and an adjusting platform. The adjusting platform is slidably connected to the frame. The frame is provided with an eighth push-pull mechanism, which controls the adjusting platform to move back and forth toward the fixed platform. The two chamfering devices, the assembly device, and the riveting device are respectively arranged on the fixed platform and the adjusting platform.

[0021] With this setup, the spacing between the two chamfering devices, assembly devices, and riveting devices can be controlled by changing the adjustment table, thus adapting to different tube lengths. In use, simply drive the eighth push-pull machine to move the adjustment table to achieve the effect of adjusting the processing length, making operation convenient.

[0022] Furthermore, the eighth push-pull machine is a motor, and a screw is provided at the output shaft position of the eighth push-pull machine. An adjustment block that is threadedly connected to the screw is provided at the bottom of the adjustment platform.

[0023] With this configuration, the eighth push-pull machine uses a motor and screw structure to provide stronger and more stable driving force. The screw, in conjunction with the adjusting block, can move the adjusting table, which includes a chamfering device, assembly device, riveting device, and other parts, toward the fixed table in one go. The adjusting table can slide on the frame using a combination of rails and rail grooves. Attached Figure Description

[0043] This specific embodiment is merely an explanation of the present embodiment and is not intended to limit the present embodiment. After reading this specification, those skilled in the art can make modifications to the present embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present embodiment.

[0044] Referring to the accompanying drawings, this utility model provides the following technical solution: an automatic pipe cutting and assembly machine, including a frame 1, a cutting device 2, a chamfering device 3, an assembly device 4, and a riveting device 5. The cutting device 2 includes a feeding mechanism 201, a cutting mechanism 202, a discharging mechanism 203, and a conveying mechanism 204. The feeding mechanism 201 is connected to the cutting mechanism 202, and the discharging mechanism 203 is connected to the cutting mechanism 202 and the conveying mechanism 204. Two chamfering devices 3, two assembly devices 4, and two riveting devices 5 are respectively arranged on both sides of the conveying mechanism 204.

[0045] With this setup, when the machine is started, the feeding mechanism 201 will move the tube material to the cutting mechanism 202 for cutting. After cutting, the unloading mechanism 203 will move the cut tube of a predetermined length to the conveying mechanism 204, which will then transport it to the chamfering device 3 for edge grinding and chamfering of both ends. After chamfering, the conveying mechanism 204 will then transport the tube to the assembly device 4 for inserting connectors at both ends. Finally, the tube will be transported to the riveting device 5 for riveting, securing the connection between the connectors and the tube. This completes the tube cutting and assembly process. The assembled tube will then be sent out of the frame 1 by the conveying mechanism 204. The entire process can be completed automatically by starting the machine, without manual operation, resulting in higher efficiency.

[0046] In a preferred embodiment, the cutting mechanism 202 includes a cutting disc 2021 and a support rod 2022, with the cutting disc 2021 facing the support rod 2022. The feeding mechanism 203 includes a first driving member 2031, which controls the support rod 2022 to reciprocate in the direction of the conveying mechanism 204.

[0047] With this setup, the feeding mechanism 201 will transport the tube to the support rod 2022. Then, the cutting disc 2021 is rotated by the motor and pushed by a push rod or similar component to insert into the side of the support rod 2022. Alternatively, the support rod 2022 can have a groove for the cutting disc 2021 to insert into, thus cutting the tube on the support rod 2022. After cutting, the tube of the required length will remain on the support rod 2022. At this point, the first driving component 2031 will control the support rod 2022 to rotate toward the conveying mechanism 204, pouring the tube on the support rod 2022 onto the conveying mechanism 204. Then, the support rod 2022 will rotate back to its original position for the next tube cutting. A cover can also be installed on the cutting disc 2021 for added safety, eliminating the need for manual operation and increasing efficiency.

[0048] In a preferred embodiment, the unloading mechanism 203 further includes a first drive rod 2032, which is rotatably connected to the frame 1. The support rod 2022 is connected to the first drive rod 2032. The first drive component 2031 is a motor, and the first drive rod 2032 is connected to the output shaft of the first drive component 2031. The above configuration is not limited. The first drive component 2031 can also be a push rod, which drives the support rod 2022 to rotate by pushing, or other conventional parts can be used for driving. Other drive components that control rotation in this application can be selected in the same way as the first drive component 2031.

[0049] With this configuration, the first drive rod 2032, which is rod-shaped, is selected as the main rotating component, making it easier to rotate and connect with the frame 1. In this way, the support rod 2022 can be freely set into the required shape to facilitate the placement of the tube and cutting.

[0050] In a preferred embodiment, the feeding mechanism 203 further includes a support hook 2033, which is hook-shaped and is positioned below the support rod 2022 and facing the conveying mechanism 204.

[0051] With this setup, the cut pipe will first fall onto the support hook 2033 and stay there temporarily. Since the support hook 2033 is a checkmark shape, the pipe will fall at the corner of the checkmark. This will help to position the pipe and prevent it from falling over due to gravity, making it easier for the conveying mechanism 204 to transport it away.

[0052] In a preferred embodiment, the feeding mechanism 203 further includes a second driving member 2034 and a second driving rod 2035. The support hook 2033 is connected to the second driving rod 2035, and the second driving rod 2035 is rotatably connected to the frame 1. The second driving member 2034 controls the second driving rod 2035 to reciprocate in the direction of the conveying mechanism 204.

[0053] With this configuration, when the conveying mechanism 204 contacts the tube on the support hook 2033, the second driving member 2034 can control the second driving rod 2035 to rotate, causing the support hook 2033 on the second rotating rod to swing downward. In this way, the conveying mechanism 204 does not need to be raised during conveying; it can simply move horizontally to remove the tube from the support hook 2033.

[0054] In this preferred embodiment, the cutting mechanism 202 further includes a positioning block 2023, and the support rod 2022 is provided with a conveying groove 20221. The positioning block 2023 is adapted to the conveying groove 20221. The above setting is not limited, and the positioning block 2023 can also be directly set on the support rod 2022 without the conveying groove 20221.

[0055] With this configuration, the conveying trough 20221 is more convenient for placing the pipe inside, making the pipe cutting process more stable. The positioning block 2023 can position the pipe inside the conveying trough 20221, positioning it after the pipe reaches a certain length on the support rod 2022.

[0056] In a preferred embodiment, the cutting mechanism 202 further includes a first push-pull mechanism 2024, which controls the positioning block 2023 to reciprocate on the support rod 2022 toward the conveying groove 20221. The above setting is not limited. One of the first push-pull mechanism 2024 and one of the positioning block 2023 can be set at each end of the support rod 2022, so that the positioning and cutting at both ends is more stable. The positioning block 2023 can also be directly set in the conveying groove 20221 and then a slot adapted to the tube body is set.

[0057] With this configuration, during cutting, the first push-pull machine 2024 will drive the positioning block 2023 to insert it into the conveying groove 20221. After cutting, the first push-pull machine 2024 will pull the positioning block 2023 out of the conveying groove 20221. At this time, the support rod 2022 can rotate freely and will not be stuck by the positioning block 2023. The first push-pull machine 2024 can also be equipped with an infrared sensor for greater sensitivity. The first push-pull machine 2024 can use conventional push-pull parts such as telescopic motors, telescopic cylinders, and hydraulic cylinders. Other push-pull machines in this application can also use the same selection as the first push-pull machine 2024.

[0058] In this preferred embodiment, the positioning block 2023 is slidably connected to the frame 1 in the conveying direction toward the conveying groove 20221.

[0059] This configuration allows the position of the positioning block 2023 to be changed to accommodate different tube lengths. A sliding connection can be achieved by setting a long rod so that the positioning block 2023 or the first push-pull machine 2024 can slide on the long rod.

[0060] In a preferred embodiment, the conveying mechanism 204 includes a second push-pull mechanism 2041, a sliding rod 2042, and a plurality of clamping components 2043. The plurality of clamping components 2043 are connected to the sliding rod 2042, and the second push-pull mechanism 2041 controls the sliding rod 2042 to reciprocate in a direction away from the cutting mechanism 202.

[0061] With this configuration, the clamping component 2043 can clamp the tube falling from the unloading mechanism 203. Then, the second push-pull machine 2041 will operate, pushing the sliding rod 2042 to move the tube to the next station. At this time, the parts at other stations will fix the tube for processing. Then, the clamping component 2043 can release the tube. Then, the second push-pull machine 2041 will pull the sliding rod 2042 back to clamp the next falling tube. After the tube is processed by other stations, it will be clamped by other clamping components 2043 on the sliding rod 2042 after being released by the station. This process is repeated to continuously transport the tube to the next position. The conveying mechanism 204 requires less space and has a higher space utilization rate.

[0062] In a preferred embodiment, the clamping assembly 2043 includes a third driving member 20431 and two opposing clamping claws 20432. The third driving member 20431 controls the clamping claws 20432 to move toward the other clamping claw 20432.

[0063] With this setup, the tube will fall between the two clamping claws 20432, and then the third drive unit 20431 can control the two clamping claws 20432 to retract, thus clamping the tube between them and ensuring stable clamping.

[0064] In this preferred embodiment, the clamping claw 20432 is rotatably connected to the third driving member 20431.

[0065] With this configuration, the gripper 20432 is in the unfolded state with both sides facing down, which does not occupy its top support surface and makes it easier to pass under the pipe being processed when moving. The third drive unit 20431 can be driven by pneumatic, electric or other means.

[0066] In this preferred embodiment, the two clamping claws 20432 are provided with a plurality of interleaved V-shaped clamping blocks 204321 on the side facing each other.

[0067] With this configuration, the V-shaped clamping block 204321 can clamp the tube body at the bend of the V-shape, making it more stable, and the clamping claws 20432 will not shift after being clamped by the staggered configuration.

[0068] In a preferred embodiment, the conveying mechanism 204 further includes a support plate 2044, which is connected to a plurality of the clamping components 2043.

[0069] With this configuration, the support plate 2044 can be used to support and stabilize the height of the tube, keeping it at the folded position of the V-shaped clamping block 204321. This way, even if the clamping claw 20432 releases the tube, the tube will not fall and will always maintain this height before being clamped by the clamping parts of other stations, making the processing more stable.

[0070] In this preferred embodiment, there are two conveying mechanisms 204, which are respectively arranged on both sides of the frame 1.

[0071] With this configuration, two conveying mechanisms 204 support the tube from both sides, allowing for the transport of long tubes through the small-volume conveying mechanisms 204.

[0072] In a preferred embodiment, the frame 1 is provided with a plurality of support bars 101 located between the two conveying mechanisms 204.

[0073] With this configuration, the support bar 101 can support the suspended tube and prevent it from bending and falling from the middle.

[0074] In a preferred embodiment, the frame 1 is provided with a plurality of sliding blocks 102, and the sliding rod 2042 is connected to the sliding block 102 via a track.

[0075] With this configuration, the sliding rod 2042 will use a track rod with an irregular cross-section, and the sliding block 102 will be provided with a matching slot for insertion. This allows the track connection to make the sliding rod 2042 slide on the frame 1 while driving all the clamping components 2043 to move together, resulting in stable movement.

[0076] In a preferred embodiment, the feeding mechanism 203 further includes a guide plate 2036, which is located between the feeding mechanism 203 and the conveying mechanism 204, and the guide plate 2036 is provided with a guide channel 20361.

[0077] With this configuration, the guide channel 20361 on the guide plate 2036 can guide the pipe that is tilted down by the feeding mechanism 203, preventing it from bouncing around. The guide channel 20361 can be formed by slotting a plate or by installing two plates one above the other with a gap.

[0078] In a preferred embodiment, the feeding mechanism 201 includes a fourth driving member 2011 and two conveying wheels 2012, wherein the fourth driving member 2011 controls the two conveying wheels 2012 to rotate in opposite directions.

[0079] With this setup, the two conveyor wheels 2012 will clamp the tube body, and when they rotate in opposite directions, they will transport the tube body to the same direction, namely the cutting mechanism 202. The structure is simple. The two conveyor wheels 2012 can be driven by two independent motors, or by one motor and two gears meshing together. Several guide wheels can also be set in front of the conveyor wheels 2012 to straighten the tube body and transport it stably. A pipe can also be set between the conveyor wheels 2012 and the cutting mechanism 202 to allow the tube body to pass through, thereby straightening the flexible tube and preventing it from bending during cutting.

[0080] In this preferred embodiment, the chamfering device 3 includes a third push-pull mechanism 301, a fifth drive component 302, and a chamfering disc 303. The fifth drive component 302 controls the rotation of the chamfering disc 303, and the third push-pull mechanism 301 controls the chamfering disc 303 to reciprocate relative to the tube body.

[0081] With this configuration, when the tube is conveyed to the chamfering device 3 by the conveying mechanism 204, the fifth drive unit 302 will be activated, driving the chamfering disk 303 to rotate. Then, the third push-pull machine 301 will push the chamfering disk 303 to move towards the tube. When the chamfering disk 303 contacts the tube, its end will be ground and chamfered. After the chamfering is completed, the third push-pull machine 301 will pull the chamfering disk 303 back, and then the fifth drive unit 302 will stop operating. The third push-pull machine 301 can directly control the chamfering disk 303 to move towards the tube, or it can control the tube to move towards the chamfering disk 303. Other relative movements in this application can also be in this form.

[0082] In a preferred embodiment, the chamfering device 3 further includes a sixth driving member 304 and a connecting plate 305. Two chamfering discs 303 are provided, and the two chamfering discs 303 are connected to the connecting plate 305. The sixth driving member 304 controls the rotation of the connecting plate 305 by positioning it between the two chamfering discs 303.

[0083] With this setup, during grinding, the sixth drive component 304 will drive the connecting plate 305 to rotate, and the two chamfering discs 303 on the connecting plate 305 will be rotated simultaneously. Each of the two chamfering discs 303 is then rotated by the fifth drive component 302. This allows for faster chamfering and grinding of the tube body, and the grinding residue is more likely to fall out from the gap between the two chamfering discs 303, making it less likely to remain on the chamfering discs 303.

[0084] In a preferred embodiment, the chamfering device 3 further includes a pin 306, and the two chamfering discs 303 are spaced apart, with the pin 306 located in the gap between the two chamfering discs 303.

[0085] With this setup, the ejector pin 306 will be inserted into the inner hole of the tube body for positioning during grinding. After the conical head of the ejector pin 306 is inserted into the inner hole, it will straighten the end angle of the tube body so that it is perpendicular to the chamfering plate 303, making the chamfering more accurate.

[0086] In this preferred embodiment, the ejector pin 306 is connected to the output shaft of the sixth driving member 304.

[0087] With this configuration, the ejector pin 306 can not only position the tube body, but also grind and chamfer the edge of the inner hole of the tube body, removing burrs caused by cutting at that location.

[0088] In this preferred embodiment, the output shaft of the sixth driving member 304 is provided with a connecting hole 3041, and the ejector pin 306 is slidably connected to it in the connecting hole 3041. The ejector pin 306 is provided with a pressure spring 3061 that applies a force to it in the opposite direction to the sixth driving member 304. The above setting is not limited, and the pressure spring 3061 can also be other elastic parts such as spring sheets.

[0089] With this setup, during chamfering, the ejector pin 306 will first contact the inner hole of the tube. Then, as the sixth drive unit 304 continues to operate and controls the chamfering disc 303 to move toward the tube, the ejector pin 306 will compress the pressure spring 3061 and retract it into the connecting socket 3041 until the chamfering disc 303 contacts the tube for chamfering. In this way, after the outer ring of the tube is chamfered, the inner hole will not be chamfered too deeply.

[0090] In a preferred embodiment, a baffle 3042 is provided inside the connecting socket 3041, the pressure spring 3061 is located between the baffle 3042 and the ejector pin 306, the ejector pin 306 is provided with a third strip groove 3062, the ejector pin 306 is provided with a positioning rod 3063, and the positioning rod 3063 passes through the output shaft of the sixth driving member 304 and is inserted into the third strip groove 3062.

[0091] With this configuration, the pressure spring 3061 will apply force to the ejector pin 306 on the baffle 3042. Installation is convenient. The baffle 3042 can be installed in a split configuration, inserted through the outer wall of the sixth drive member 304 into the connecting hole 3041. Alternatively, the connecting hole 3041 can be made into a blind hole, with the bottom surface of the blind hole serving as the baffle 30472. After the ejector pin 306 is connected by inserting the positioning rod 3063 into the third strip groove 3062, its sliding distance can be limited, preventing it from being pushed out by the pressure spring 3061. The ejector pin 306 can still rotate with the output shaft.

[0092] In this preferred embodiment, the chamfered disk 303 is frustum-shaped.

[0093] With this design, the inclined surface of the frustum only needs to rotate normally to bevel the tube in contact with it, resulting in a simple structure.

[0094] In this preferred embodiment, a clamping component 2043 is provided at the position between the chamfering device 3 and the conveying mechanism 204.

[0095] With this configuration, the clamping component 2043 will clamp the tube body during chamfering, preventing the tube body from moving and affecting the chamfering effect. The clamping component 2043 can use the same structure as the conveying mechanism 204.

[0096] In a preferred embodiment, the chamfering device 3 further includes a protective cover 307, and the chamfering disc 303 is located in the protective cover 307. The protective cover 307 has a movable groove 3071 that runs through both sides of the protective cover 307 on the side facing the conveying mechanism 204. The above setting is not limited, and the grinding mechanism 310 and the riveting device 5 in this application can also be provided with independent protective covers 307.

[0097] With this configuration, the protective cover 307 can cover the chamfering disc 303 of the chamfering device. The debris generated by the chamfering device 3 during the chamfering process will be contained by the protective cover 307 and will not fly around. The tube body can move through the movable groove 3071 without being interfered with by the protective cover 307.

[0098] In a preferred embodiment, the chamfering device 3 further includes a sliding frame 308 and a sliding rail 309. The sliding rail 309 is connected to the frame 1, the chamfering disc 303 is connected to the sliding frame 308, the sliding frame 308 is slidably connected to the sliding rail 309, and the sliding frame 308 is connected to the output shaft of the third push-pull machine 301.

[0099] With this configuration, the sliding frame 308 will have a groove that matches the sliding rail 309, so that it can slide stably on the sliding rail 309 after insertion. When the chamfering device 3 is in operation, the third push-pull machine 301 is driven by a power source such as air or electricity to push the output shaft towards the tube body, which can push the sliding frame 308, causing the chamfering disk 303 on the sliding frame 308 to move towards the tube body. At the same time, other parts such as the sixth drive component 304 can also be mounted on the sliding frame 308.

[0100] In a preferred embodiment, the chamfering device 3 further includes a grinding mechanism 310. The grinding mechanism 310 is located on the side of the chamfering disc 303 facing away from the feeding mechanism 203. The grinding mechanism 310 includes a fourth push-pull mechanism 3101, a seventh drive member 3102, and a grinding member 3103. The seventh drive member 3102 controls the grinding member 3103 to rotate, and the fourth push-pull mechanism 3101 controls the grinding member 3103 to reciprocate relative to the tube body.

[0101] With this configuration, the grinding mechanism 310 will grind the end of the chamfered tube to remove the burrs on the chamfered surface, making it easier to insert the connector. During grinding, the seventh drive component 3102 will drive the grinding component 3103 to rotate, and then the fourth push-pull mechanism 3101 will push the grinding component 3103 toward the tube. Once they come into contact, grinding can begin. After grinding, the component will return to its original position. A clamping component 2043 can also be provided between the grinding mechanism 310 and the tube for stability. The sliding method of the grinding mechanism 310 can also be the same as that of the chamfering device 3, using a sliding frame 308 and a sliding track 309.

[0102] In this preferred embodiment, the grinding component 3103 is a wire brush.

[0103] With this setup, the wire brush can remove burrs from products of various shapes, making it widely applicable and causing minimal damage to parts.

[0104] In a preferred embodiment, the assembly device 4 includes a vibratory feeder 401, a conveyor belt 402, and a robotic arm 403. The conveyor belt 402 is connected to the vibratory feeder 401, and the robotic arm 403 is located on the side of the conveyor belt 402 facing the conveying mechanism 204.

[0105] With this setup, a large number of connectors are placed inside the vibratory feeder 401. During vibration, the connectors are moved to the conveyor belt 402 for transport. When they reach the tube body, the robotic arm 403 will operate to clamp the connectors and insert them into the end of the tube body, without the need for manual operation.

[0106] In a preferred embodiment, the assembly device 4 further includes a fifth push-pull mechanism 404, an eighth drive component 405, and a rotating disk 406. The robotic arm 403 is connected to the rotating disk 406. The eighth drive component 405 controls the rotating disk 406 to rotate, and the fifth push-pull mechanism 404 controls the robotic arm 403 to reciprocate relative to the tube body.

[0107] With this setup, during assembly, the connector moves to a position below the robot arm 403. The robot arm 403 clamps the connector, and then the eighth drive unit 405 drives the rotating disk 406 to rotate, thereby controlling the robot arm 403 to turn towards the tube body. Then, the fifth push-pull mechanism 404 controls the robot arm 403 to move towards the tube body, so that the connector can be inserted into the end of the tube body. Afterward, the robot arm 403 releases and retracts, eliminating the need for manual operation and increasing efficiency. The robot arm 403 can be pneumatic, electric, or other types. A clamping component 2043 can also be set between the assembly device 4 and the tube body for stability. The sliding method of the assembly device 4 can also be the same as that of the chamfering device 3, using a sliding frame 308 and a sliding track 309.

[0108] In a preferred embodiment, the riveting device 5 includes a riveting frame 501, a ninth driving member 502, a sixth push-pull mechanism 503, and a plurality of riveting blocks 504. The riveting frame 501 is provided with riveting holes 5011, and the plurality of riveting blocks 504 are located in the riveting holes 5011. The ninth driving member 502 controls the riveting blocks 504 to reciprocate toward the center of the riveting holes 5011, and the sixth push-pull mechanism 503 controls the riveting frame 501 to reciprocate relative to the tube body.

[0109] With this setup, during riveting, the sixth push-pull machine 503 will control the tube body to enter the riveting hole 5011 on the riveting frame 501. After entering, the ninth drive unit 502 drives several riveting blocks 504 to move toward the joint on the tube body until it is clamped and riveted. Then the riveting blocks 504 retract, and the sixth push-pull machine 503 pulls the tube body out. At this time, the joint will be fixed to the end of the tube body by the riveting deformation. Then it can continue to be transported to the rear. The whole process does not require manual operation and is more efficient.

[0110] In a preferred embodiment, the outer wall of the riveting frame 501 is provided with a riveting groove 5012 that communicates with the riveting hole 5011 and is adapted to the riveting block 504. The riveting groove 5012 is provided with a reset member 5013 that applies a force to the riveting block 504 in the opposite direction to the riveting hole 5011.

[0111] With this configuration, during installation, the rivet block 504 can be directly inserted from the rivet groove 5012 on the outer wall of the rivet frame 501. During use, simply push the rivet block 504 from the outside to move it toward the center of the rivet hole 5011 to achieve the riveting effect. After the riveting is completed, when the rivet block 504 is no longer pushed, it will be pushed back to its original position by the reset member 5013.

[0112] In a preferred embodiment, the riveting block 504 is provided with a first strip groove 5041, and the riveting block 504 is provided with a positioning rod 5042, which penetrates the outer wall of the riveting frame 501 and is inserted into the first strip groove 5041.

[0113] With this configuration, after inserting the rivet block 504 into the rivet groove 5012 during installation, the positioning rod 5042 can be inserted through the rivet frame 501 into the first strip groove 5041. This restricts the movement of the rivet block 504 within the range of the first strip groove 5041, preventing it from being pushed out of the rivet groove 5012 by the reset member 5013. This results in a more stable structure and easier installation. A detachable mounting block can also be provided at the position on the rivet frame 501 where the rivet block 504 is installed to process the rivet groove 5012, facilitating processing and installation.

[0114] In this preferred embodiment, the riveting block 504 has a reset groove 5043 on the side facing the riveting hole 5011, the riveting frame 501 has a reset block 5014 at the bottom of the riveting groove 5012, and the reset member 5013 is a spring disposed between the reset block 5014 and the reset groove 5043.

[0115] With this configuration, the spring will be in the reset groove 5043, while the reset block 5014 is stabilized on the riveting frame 501. The force exerted by the spring on the riveting block 504 can push the riveting block 504 to move toward the opening of the riveting groove 5012. The structure is simple and the reset is stable.

[0116] In this preferred embodiment, the reset block 5014 and the riveting frame 501 are detachably connected.

[0117] With this configuration, the riveting groove 5012 can be directly designed as a through hole, which makes it easier to process. The reset block 5014 can be connected to the riveting frame 501 by conventional methods such as bolt connection.

[0118] In a preferred embodiment, the riveting device 5 further includes a top pressing member 505. The ninth driving member 502 is a push-pull machine that controls the top pressing member 505 to move toward the riveting frame 501. The side of the riveting block 504 facing away from the center of the riveting hole 5011 is an inclined surface that is oriented toward the top pressing member 505 with a reduced diameter. The top pressing member 505 is provided with a top pressing block 5051 at the position corresponding to the inclined surface of the riveting block 504.

[0119] With this configuration, the ninth driving component 502 can use conventional structures such as pneumatic push rods, electric push rods, and hydraulic push rods. When in use, it drives the top pressing component 505 to move toward the riveting frame 501. After moving, the top pressing block 5051 will first contact the inclined surface of the riveting block 504 exposed outside the riveting groove 5012. In this way, during the pushing process, the riveting block 504 will be driven to move toward the center of the riveting hole 5011. The pushing process is stable. The position of the riveting groove 5012 on the riveting frame 501 can also be set in a conical or frustum shape to facilitate the pushing of the top pressing component 505.

[0120] In a preferred embodiment, the riveting device 5 further includes a positioning pin 506, which is connected to the output shaft of the ninth driving member 502.

[0121] With this setup, during riveting, the positioning pin 506 will be inserted into the inner hole of the connector or pipe to position it. After the conical head of the positioning pin 506 is inserted into the inner hole, it will straighten the end angle of the pipe and connector so that they are perpendicular to the riveting hole 5011, making the riveting position more accurate.

[0122] In this preferred embodiment, the positioning pin 506 is slidably connected to the pressing member 505. The positioning pin 506 is provided with a reset plate 5061. The side of the reset plate 5061 facing the pressing member 505 is provided with a reset spring 5062 sleeved on the outer wall of the positioning pin 506. The above setting is not limited, and the reset spring 5062 can also be other elastic structures such as spring sheets.

[0123] With this setup, the positioning pin 506 will be in an active state. When the ninth drive component 502 moves, the positioning pin 506 first contacts the tube body and the connector. Then, the positioning pin 506 compresses the return spring 5062 and moves until the riveting is completed. During this period, the positioning pin 506 always presses against the connector to position it, but will not damage the connector.

[0124] In a preferred embodiment, the top pressing member 505 is provided with a connecting block 5052, the connecting block 5052 is provided with a reset insertion hole 50521 adapted to the positioning pin 506, the positioning pin 506 is provided with a second strip groove 5063, the positioning pin 506 is provided with a positioning strip 5064, and the positioning strip 5064 penetrates the outer wall of the connecting block 5052 and is inserted into the second strip groove 5063.

[0125] With this setup, during installation, the positioning pin 506 is inserted into the reset socket 50521, and then the positioning strip 5064 is inserted through the outer wall of the connecting block 5052 into the second strip groove 5063. In this way, the positioning pin 506 completes the sliding connection and is limited, so it will not pop out, making installation convenient. The connecting block 5052 can be detachably connected to the top pressing part 505 with bolts or other parts, which is convenient for processing. The reset socket 50521 can be a through hole, and the output shaft of the ninth driving part 502 can also be set to be hollow to facilitate the movement of the positioning pin 506.

[0126] In this preferred embodiment, a clamping assembly 2043 is provided at the position of the output shaft of the sixth push-pull machine 503, and the sixth push-pull machine 503 is connected to the riveting frame 501 on the side facing the tube body.

[0127] With this setup, the sixth push-pull machine 503 will control the clamping assembly 2043 on the riveting frame 501 to clamp the tube body and move it toward the riveting groove 5012. Since the riveting device 5 is relatively heavy, it is more labor-saving to control the movement of the lighter tube body. The riveting devices 5 on both sides no longer operate at the same time, and can achieve the riveting effect by using them separately. The clamping assembly 2043 can use the same structure as the conveying mechanism 204, wherein the width of the clamping claw 20432 can be set to be larger, and the number of V-shaped blocks 204321 can be set to be more.

[0128] In a preferred embodiment, the riveting device 5 further includes a seventh push-pull machine 507, which is connected to the frame 1 on the side of the tube body facing away from the riveting frame 501. A clamping assembly 2043 is provided at the output shaft position of the seventh push-pull machine 507.

[0129] With this configuration, the other end of the tube will be clamped by another clamping component 2043, and then driven by the seventh push-pull machine 507 to move together toward the riveting hole 5011. The movement is more stable with both ends of the tube being clamped at the same time.

[0130] In this preferred embodiment, the top of the frame 1 is provided with a fixed platform 103 and an adjusting platform 104. The adjusting platform 104 is slidably connected to the frame 1. The frame 1 is provided with an eighth push-pull mechanism 105. The eighth push-pull mechanism 105 controls the adjusting platform 104 to move back and forth in the direction of the fixed platform 103. The two chamfering devices 3, the assembly device 4, and the riveting device 5 are respectively arranged on the fixed platform 103 and the adjusting platform 104.

[0131] With this setup, the spacing between the two chamfering devices 3, the assembly device 4, and the riveting device 5 can be controlled by changing the adjustment table 104, thereby adapting to different tube lengths. In use, simply drive the eighth push-pull machine 105 to move the adjustment table 104 to achieve the effect of adjusting the processing length, which is convenient to operate.

[0132] In this preferred embodiment, the eighth push-pull machine 105 is a motor, and a screw 1051 is provided at the output shaft position of the eighth push-pull machine 105. An adjustment block 1041 that is threadedly connected to the screw 1051 is provided at the bottom of the adjustment table 104.

[0133] With this configuration, the eighth push-pull machine 105 uses a motor and screw 1051 structure to provide stronger and more stable driving force. The screw 1051, in conjunction with the adjusting block 1041, can move the adjusting table 104, which includes the chamfering device 3, assembly device 4, riveting device 5, and other parts, toward the fixed table 103 in one go. The adjusting table 104 can slide on the frame 1 using a track and track groove.

[0134] In a preferred embodiment, the frame 1 includes a main frame 106 and a sub-frame 107. The fixed platform 103 and the adjusting platform 104 are respectively located on the main frame 106 and the sub-frame 107, and a gap is provided between the fixed platform 103 and the adjusting platform 104.

[0135] With this setup, since the parts are all placed at both ends of the tube during processing, it would be wasteful to place the frame 1 in the space between them. Therefore, setting up the sub-frame 107 to leave the middle empty can avoid wasting space on the frame 1.

[0136] In this preferred embodiment, the frame 1 is provided with a plurality of material collection hooks 108 at the end of the conveying mechanism 204. The above setting is not limited, and a box can also be provided at the end of the conveying mechanism 204 to collect the pipe body.

[0137] With this setup, the processed pipes will fall onto the collecting hook 108, eliminating the need for manual collection of each pipe, which is more convenient. At the same time, the collecting hook 108 can be slidably connected to the frame 1 to accommodate pipes of different lengths.

[0138] Although the present invention has been described in detail with reference to the foregoing embodiments, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be included within the scope of protection of the present invention.
