[0002] In the manufacturing and processing of mechanical parts, some pipe fittings require outer diameter turning. Using lathe tools, the outer surface of the pipe fitting is machined to the required diameter, surface finish, and dimensional accuracy. Currently, this process often involves manual handling of the pipe fittings, which are then manually installed and adjusted on the corresponding lathe. This manual installation and adjustment is time-consuming, especially in mass production, making this method inefficient. Each adjustment and installation wastes time and reduces overall production efficiency. Summary of the Invention

A push plate is fixedly connected to the output end of the feeding cylinder. An arc-shaped structure for workpiece cooperation is fixedly connected to the top of the push plate. When the feeding cylinder drives the push plate to extend, the arc-shaped structure pushes the workpiece between the first support pin and the second support pin. At the same time, the push plate limits the material on the guide groove.

[0005] Preferably, the clamping drive assembly includes a support base one and a support base two fixedly connected to the top two ends of the support groove. A drive motor is fixedly connected to one side of the support base one, and a support pin one is rotatably installed in the middle of the support base one.

[0010] Preferably, a linear module three is fixedly connected to the top of the storage rack. A pusher plate for driving the workpiece to move laterally is fixedly connected to the sliding surface of the linear module three. A limiting guide rod is fixedly connected to the top of the linear module three. Connecting rods are slidably connected to both ends of the limiting guide rod. An inclined support wheel is fixedly connected to one side of each connecting rod for supporting and guiding the workpiece from the bottom.

[0011] Preferably, the top of the linear module three is fixedly connected to a dual-axis cylinder that drives the connecting rod to move. The middle part of the connecting rod and the support wheel are alternately arranged with extrusion wheels. The middle part of the extrusion wheel has an arc-shaped structure for guiding and limiting the workpiece. A fixed clamp is fixedly connected to the outside of the support wheel located near the guide groove for clamping and fixing the workpiece.

[0012] Compared with the prior art, the beneficial effects of this invention are as follows: Automatic feeding of pipe fittings is achieved through the cooperation of a feeding cylinder, a push plate, and a guide trough; when the feeding cylinder retracts, the pipe fitting to be processed rolls down into the arc-shaped structure at the end of the push plate and limits the remaining pipe fittings; during extension, the pipe fitting is pushed between the support pins, and during reset, the pipe fitting at the end of the guide trough rolls down again to the top of the push plate. The entire process requires no frequent manual operation, improving feeding efficiency; when the feeding cylinder drives the push plate to push the pipe fitting to its limit position, the controller controls the hydraulic cylinder to drive the support pins to move towards the first support pin, automatically squeezing and fixing the pipe fitting, achieving automated clamping; the drive motor drives the first support pin to rotate through the transmission belt assembly, thereby… The system rotates the pipe fitting, while the linear module and cylinder work together to move the cutting tool holder so that the cutting tool contacts the outer side of the pipe fitting, achieving automatic cutting of the outer surface of the pipe fitting and reducing manual intervention. When the end of the pipe fitting contacts the sensor, the controller controls the extrusion cylinder to clamp the pipe fitting, and the lifting cylinder drives the cutting machine to descend to cut the pipe fitting. After cutting, the extrusion cylinder resets, and the cut pipe fitting rolls along the guide groove, realizing automated cutting. The second linear module drives the lifting plate to raise and lower the pipe fitting, and the third linear module drives the pipe fitting to move laterally through the pusher plate. The dual-axis cylinder drives the support wheel and extrusion wheel to move, realizing automatic material storage, support, guidance and pushing of the pipe fitting, which facilitates the cutting machine to cut the pipe fitting in sections.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-8 This invention provides a technical solution: a mechanical parts manufacturing and processing device, comprising: a U-shaped support groove 1, a clamping and driving assembly mounted on the top of the support groove 1, the clamping and driving assembly including a first support pin 4 and a second support pin 31, used for positioning and driving workpiece rotation; an outer diameter turning assembly placed on one side of the support groove 1, the outer diameter turning assembly including a movable tool holder 10 on which a turning tool 11 is mounted, a driving part mounted on the bottom of the movable tool holder 10, used for driving the turning tool 11 to move horizontally; and a loading assembly placed in the middle of the support groove 1. The feeding assembly includes a guide trough 14 that is inclined and fixed to one side. The guide trough 14 is located at one end of the support trough 1 and is inclined downward. A feeding cylinder 12 is inclined and fixed to the support trough 1 at the position corresponding to the guide trough 14. A push plate 13 is fixedly connected to the output end of the feeding cylinder 12. An arc-shaped structure for workpiece cooperation is fixedly connected to the top of the push plate 13. When the feeding cylinder 12 drives the push plate 13 to extend, the arc-shaped structure pushes the workpiece between the support pin 1 4 and the support pin 2 31. At the same time, the push plate 13 limits the material on the guide trough 14.

[0017] It should be noted that in this embodiment, a controller and a corresponding operating switch are provided. When the feeding cylinder 12 is in the retracted state, the tube to be processed rolls down into the arc-shaped structure at the end of the push plate 13, and it squeezes and limits the other tubes. When the push plate 13 drives the feeding cylinder 12 to lift the top tube, the tube at the very end inside the multi-guide groove 14 on the side of the push plate 13 is blocked, thereby limiting the tube inside the guide groove 14. When the feeding cylinder 12 drives the push plate 13 to extend to the limit position, the tube at the end of the push plate 13 is located between the first support pin 4 and the second support pin 31. Concentrically, at this moment, the second support pin 31 moves to one side, clamping the pipe between the first support pin 4 and the second support pin 31. When the feeding cylinder 12 drives the push plate 13 to reset, the pipe at the end of the guide groove 14 rolls down to the top of the push plate 13 again. The pipe is driven to rotate by the first support pin 4, and the cutting tool 11 contacts the outer side of the key under the action of the drive unit, thereby machining the outer side of the pipe. After machining, the first support pin 4 and the second support pin 31 separate, allowing the machined pipe to fall and separate. The whole process is automated, reducing manual operation and improving production efficiency. The cooperation of the guide groove and the pins effectively avoids the positional deviation of the pipe and improves the machining accuracy. The stable clamping of the pipe reduces machining errors or safety accidents caused by pipe vibration or loosening. The feeding, clamping, machining and separation of the pipe are carried out automatically, reducing downtime and manual intervention.

[0018] In one embodiment, the clamping drive assembly includes a first support 3 and a second support 5 fixedly connected to the top two ends of the support groove 1. A drive motor 2 is fixedly connected to one side of the first support 3. A first support pin 4 is rotatably installed in the middle of the first support 3. The output end of the drive motor 2 is connected to the first support pin 4 via a transmission belt assembly. A hydraulic cylinder 6 is fixedly connected to one side of the second support 5. The output end of the hydraulic cylinder 6 passes through the second support 5 and is rotatably connected to a second support pin 31. The first support pin 4 and the second support pin 31 are concentric. A receiving groove 15 is obliquely fixedly connected in the middle of the support groove 1 and between the first support pin 4 and the second support pin 31.

[0019] It should be noted that in this embodiment, when the feeding cylinder 12 reaches the limit of the tube through the push plate 13, under the action of the limit switch, the controller controls the hydraulic cylinder 6 to drive the second support pin 31 to move towards the first support pin 4, thereby squeezing and fixing the tube between the first support pin 4 and the second support pin 31. Then, the feeding cylinder 12 drives the push plate 13 to reset, and then the drive motor 2 drives the large pulley to rotate through the small pulley. The large pulley drives the first support pin 4 to rotate, thereby rotating the tube squeezed between the first support pin 4 and the second support pin 31. After processing, when the second support pin 31 moves away from the first support pin 4, the workpiece falls onto the receiving groove 15 and is discharged downwards. The entire process, from feeding, clamping, rotation processing to discharge, is almost completely automated, reducing manual operation and improving production efficiency. The clamping action of the first support pin 4 and the second support pin 31 ensures the stability of the tube during processing and avoids processing errors caused by vibration or eccentricity. The drive motor and belt system rotate the support pin 4, ensuring stable speed and precision in the processing of the pipe fittings. The processed pipe fittings are discharged downwards through the receiving trough 15, simplifying subsequent processing.

[0020] In one embodiment, the drive unit includes a linear module 7 fixedly attached to one side of the support groove 1. A movable stage 8 is fixedly attached to the movable slide of the linear module 7. The movable stage 8 is perpendicular to the linear module 7. A movable tool holder 10 is slidably connected to the top of the movable stage 8. A cylinder 9 for driving the movable tool holder 10 is fixedly connected to the top of the movable stage 8.

[0021] It should be noted that in this embodiment, the linear module 7 is arranged along the length direction of the support groove 1, that is, the linear module 7 is parallel to the axis direction of the support pin 4 and the support pin 31. The moving slide of the linear module 7 drives the moving table 8 along the length direction of the support groove 1. The length direction of the moving table 8 is perpendicular to the length direction of the linear module 7. The cylinder 9 drives the moving tool holder 10 to slide on the top of the moving table 8. The moving tool holder 10 drives the cutting tool 11 to contact the outer side of the pipe. Under the action of the linear module 7 and the cylinder 9, the moving tool holder 10 can move along the X-axis and Y-axis to achieve the cutting of the outer surface of the pipe. Through the cooperation of the linear module and the cylinder, precise X-axis and Y-axis motion control can be achieved to ensure the contact accuracy between the cutting tool and the outer surface of the pipe. It can realize all-round cutting of the outer surface of the pipe and adapt to pipes of various lengths and sizes. The automated control of the pneumatic and linear drive system makes the entire processing process free from manual intervention, which greatly improves production efficiency.

[0022] In one embodiment, a support frame 16 is fixedly connected to one end of the feed chute 14, and extrusion cylinders 17 for fixing workpieces are fixedly connected to both sides of the support frame 16. A lifting cylinder 18 is fixedly connected to the top of the extrusion cylinder 17, and the output end of the extrusion cylinder 17 is fixedly connected to the support frame 16. The top of the support frame 16 has a plurality of metal rods that are slidably connected to the lifting cylinder 18. A cutting machine 19 is fixedly connected to one side of the support frame 16. The cutting machine 19 includes a motor and a cutting blade.

[0023] It should be noted that, in this embodiment, an infrared sensor is installed at one end of the support frame 16 to detect the position of the pipe end. When the pipe end contacts the infrared sensor, the controller controls the extrusion cylinder 17 to operate. The end of the extrusion cylinder 17 is fixedly connected to a V-shaped clamping block to clamp the pipe. The lifting cylinder 18 retracts. Because its piston rod is fixedly connected to the support frame 16, under the pulling force, the cylinder body of the lifting cylinder 18 moves downward outside the metal rod, thereby driving the cutting machine 19 to descend. With the reset of the lifting cylinder 18, the cutting machine 19 rises and falls to cut the pipe that extends into the support frame 16. After cutting, the extrusion cylinder 17 resets, and the cut pipe rolls downward along the guide groove 14. The infrared sensor can accurately detect the end of the pipe, ensuring that the pipe is in the correct position before cutting, avoiding misoperation. The V-shaped clamping block ensures that the pipe is firmly clamped, ensuring that no movement occurs during the cutting process and avoiding processing errors. The automated coordination of the lifting cylinder, the extrusion cylinder, and the cutting machine ensures stable and efficient processing of pipe fittings throughout the entire cutting process. The lifting cylinder controls the vertical movement of the cutting machine, ensuring a smooth cutting process and improving processing quality.

[0024] In one embodiment, the storage component further includes a storage rack 20 fixedly attached to one side of the guide trough 14. A lifting plate 22 is vertically slidably connected inside the storage rack 20. A linear module 21 is fixedly attached to one side of the storage rack 20. The movable slide of the linear module 21 is fixedly connected to the lifting plate 22.

[0025] It should be noted that in this embodiment, the top side of the storage rack 20 is provided with multiple supports for supporting and limiting the pipes. The pipes to be cut are stacked vertically above the lifting plate 22. Under the side limiting of the linear module 21, the pipes are stacked vertically downwards. After the pipe at the top is cut, the linear module 21 drives the pipe to move upward through the lifting plate 22, so that the pipe above is aligned with the support frame 16 again, which facilitates segmented cutting.

[0026] In one embodiment, a linear module 23 is fixedly connected to the top of the storage rack 20. A pusher plate 30 for driving the workpiece to move laterally is fixedly connected to the sliding surface of the linear module 23. A limiting guide rod 29 is fixedly connected to the top of the linear module 23. A connecting rod 25 is slidably connected to both ends of the limiting guide rod 29. An inclined support wheel 26 is fixedly connected to one side of the connecting rod 25 for supporting and guiding the workpiece from the bottom. A dual-axis cylinder 24 for driving the connecting rod 25 is fixedly connected to the top of the linear module 23. An extrusion wheel 27 is alternately arranged between the middle of the connecting rod 25 and the support wheel 26. The middle of the extrusion wheel 27 has an arc-shaped structure for guiding and limiting the workpiece. A fixing clamp 28 is fixedly connected to the outside of the support wheel 26 located near the guide groove 14 for clamping and fixing the workpiece.

[0027] It should be noted that, in this embodiment, an infrared sensor for detecting pipe fittings is installed at one end of the linear module 21 near the guide trough 14. After the pipe fitting is segmented and cut, the controller controls the linear module 21 to drive the lifting plate 22 to lift the topmost pipe fitting to the position opposite the support frame 16. Simultaneously, the dual-axis cylinder 24 drives the connecting rods 25 on both sides to move, thereby pushing the support rollers 26 and the extrusion rollers 27 towards both sides of the linear module 3 23. When the linear module 21 delivers the top pipe fitting to the designated height, the dual-axis cylinder 24 drives the support rollers 26 on both sides to move towards the center, thus supporting the bottom of the pipe fitting and ensuring that the pipe fitting is aligned with the support frame 16. The bottom pipe is separated, and the extrusion roller 27 fits against the side of the pipe. The arc-shaped structure of the extrusion roller 27 prevents the pipe from moving up and down. The fixing clamp 28 is placed on the outside of the pipe and slidably connected to it. The linear module 3 23, through the pusher plate 30, drives the pipe to slide along the support roller 26 and extrusion roller 27 to one end. When its end contacts the infrared sensor at one end of the support frame 16, the extrusion cylinder 17 extrudes and fixes it. The cutting machine 19 lifts and cuts it. The cut pipe falls into the guide groove 14, where it is clamped by the feeding cylinder 12 and the push plate 13, and then processed by the corresponding support pins 4 and 31. The lifting plate 22 and the infrared sensor ensure that the pipe can be accurately lifted and lowered to the designated position. The support roller, extrusion roller, and fixing clamp ensure that the pipe is stably fixed throughout the conveying and cutting process, avoiding offset and vibration during processing. Through the coordinated operation of various automated components such as linear modules, cylinders, and sensors, the entire process of pipe conveying, cutting, and clamping is effectively automated, greatly improving production efficiency. After cutting, the pipe can be quickly conveyed through the guide chute and clamped by the cooperation of the feeding cylinder and the push plate, ensuring smooth transmission and subsequent processing of the cut pipe.
