[0003] Currently, in the prior art, for square pipe welding, a C-shaped bevel needs to be pre-processed so that it can be assembled with a round pipe for welding. For the intelligent manufacturing of square pipes, an automated bevel milling device is required to complete the automated and intelligent processing and production of square pipes. This device mainly drives the milling cutter to rotate at high speed through the machine head, and then makes the milling cutter move along a corresponding trajectory to complete the milling of the square pipe bevel.

[0004] However, during use, during the milling process, the collision between the milling cutter and the square pipe causes the square pipe to vibrate to a certain extent, which in turn causes the square pipe to displace, resulting in a decrease in milling accuracy, and thus a decrease in the fit between the square pipe bevel and the round pipe to be welded, which in turn affects the subsequent welding. Therefore, an automatic square pipe bevel milling device is proposed for the above problems. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Specific embodiments are given below.

[0022] Please refer to Figures 1-5As shown, the automatic square pipe bevel milling equipment includes a workbench 11; a fixed frame is fixedly connected to the top of the workbench 11; an adjustment assembly is provided on the side of the workbench 11; a milling head 15 is provided on the adjustment assembly; a milling cutter is fixedly connected to the output end of the milling head 15; a driving electric push rod 16 is fixedly connected to the top of the fixed frame; a cross bar 17 is fixedly connected to the output end of the driving electric push rod 16; a hinge seat is slidably connected to the cross bar 17; the hinge seat is hinged to the head 15; a lifting hydraulic cylinder 12 is fixedly connected to the bottom of the workbench 11; a flat plate 13 is fixedly connected to the output end of the lifting hydraulic cylinder 12; a fixing plate 14 is fixedly connected to the top of the fixed frame at a position corresponding to the flat plate 13; a longitudinal push hydraulic cylinder 18 is fixedly connected to the front side of the workbench 11; during use, the staff hoists and places the square pipe on the workbench 11, and then starts the longitudinal push hydraulic cylinder 18 to push the square pipe to move above the flat plate 13. The longitudinal push hydraulic cylinder 18 is in a retracted state in the initial state. After the square pipe moves above the flat plate 13, the longitudinal push hydraulic cylinder 18 is reset. The lifting hydraulic cylinder 12 is started to drive the flat plate 13 to move upward. The lifting hydraulic cylinder 12 is in a retracted state in the initial state. The square pipe is clamped and fixed by the cooperation of the flat plate 13 and the fixing plate 14. With the above settings, during the milling process, the square pipe is clamped and fixed, so as to reduce the influence of shaking on the milling accuracy during the milling process, and further reduce the fit degree between the bevel and the pipe to be welded in the subsequent process, thereby reducing the influence on welding.

[0023] Further, as Figures 1-2 and Figure 6As shown in the figure, the adjusting assembly includes an adjusting rod 22; a first bracket is fixedly connected to the side of the workbench 11; a moving seat 21 is slidably connected to the top of the first bracket; the end of the adjusting rod 22 is rotatably connected to the side of the moving seat 21 away from the workbench 11; a support rod 23 is slidably connected to the adjusting rod 22; the top of the support rod 23 is fixedly connected to the machine head 15; a first screw rod 24 is rotatably connected to the top of the first bracket; the first screw rod 24 passes through the moving seat 21 and is threadedly connected thereto; the middle of the adjusting rod 22 is rotatably connected to a second screw rod 25; the second screw rod 25 passes through the bottom of the support rod 23 and is threadedly connected thereto; during use, relying on the push of the driving electric push rod 16 to drive the cross bar 17, the hinge seat and the machine head 15 to move, so that the support rod 23 and the adjusting rod 22 rotate around the rotating connection of the moving seat 21, and then drive the milling cutter to rotate around the rotating connection of the moving seat 21 as the center, so as to complete the milling of the square tube groove. During the production process, the sizes of the round tubes to be welded are different, so that the groove of the square tube needs to be adjusted. At this time, the position of the moving seat 21 can be adjusted by rotating the first screw rod 24, so as to adjust the center point of the rotation of the milling cutter, so as to adjust the groove, and then rotate the second screw rod 25, so that the support rod 23 moves in the opposite direction by the same length, and then the original position of the movement of the milling cutter. With the above settings, the applicable range of the embodiment of the present invention can be improved, it is convenient to mill grooves of different sizes, which is convenient for the staff to use. The motor inside the machine head 15 fixes and installs the milling cutter through a chuck, and the motor inside the machine head 15 drives the milling cutter to rotate and mill.

[0024] Further, as Figures 3-4 shown in the figure, a first moving frame 31 and a second moving frame 32 are slidably connected to the bottom of the flat plate 13; first racks are fixedly connected to both sides of the first moving frame 31; second racks are fixedly connected to both sides of the second moving frame 32; a pair of gears 33 are rotatably connected to the bottom side of the flat plate 13; the gears 33 are meshed with the first racks and the second racks; a screw cylinder 34 is fixedly connected to the bottom of the gears 33; a driving screw rod 35 is fixedly connected to the middle of the screw cylinder 34; the bottom end of the driving screw rod 35 is fixedly connected to the workbench 11; turning components are arranged on both sides of the flat plate 13; clamping plates 36 are arranged on the turning components; during use, as the flat plate 13 moves upward, the driving screw rod 35 is continuously pulled out from the screw cylinder 34, and then the screw cylinder 34 and the gears 33 can be rotated. The gears 33 are located between the first gear 33 and the second gear 33, so as to drive the first racks, the second racks, the first moving frame 31 and the second moving frame 32 to approach each other, so as to drive the clamping plates 36 on both sides to approach each other, so as to fix the square tube and position the square tube, so that the square tube moves to the center position of the flat plate 13, so as to facilitate subsequent milling, reduce the influence of misalignment on the milling accuracy, and facilitate subsequent welding.

[0025] Furthermore, as Figures 3-4 shown, the flipping assembly includes a flipping plate 43; a pair of flipping plates 43 are hinged to the sides of the first moving frame 31 and the second moving frame 32; a torsion spring is installed at the hinge of the flipping plate 43; a first pulley 42 is rotatably connected to the side of the flipping plate 43; a first spring is fixedly connected to the side of the flipping plate 43 away from the first pulley 42; the end of the first spring is fixedly connected to the clamping plate 36; a guide plate 41 is fixedly connected to the position corresponding to the first pulley 42 on the bottom side of the flat plate 13; during the upward movement of the flat plate 13, the first pulley 42 slides on the guide plate 41, and both sides of the guide plate 41 are designed in a Z-shaped structure, and the first pulley 42 slides upward along the inclined surface of the guide plate 41, so that the flipping plate 43 flips upward. The initial states of the flipping plate 43 and the clamping plate 36 are parallel to the flat plate 13, and are perpendicular to the flat plate 13 after flipping. With this setting, the situation where the clamping plate 36 hinders can be reduced, which is convenient for pushing the square tube onto the flat plate 13. At the same time, the setting of the first spring can facilitate adapting to square tubes of different widths and improve the adaptation range. The torsion spring is used to reset the flipping plate 43.

[0026] Furthermore, as Figures 2-3 shown, a vertical rod is fixedly connected to the side of the workbench 11 away from the first bracket; a pair of spring telescopic rods 53 are fixedly connected to the vertical rod; an arc-shaped plate 54 is fixedly connected to the side of the spring telescopic rod 53 close to the first bracket; the arc-shaped plate 54 is arranged in a V shape; a vertical plate 51 is fixedly connected to the side of the workbench 11 close to the first bracket; a positioning seat 52 is slidably connected to the bottom of the flat plate 13 away from the first bracket; a second spring is fixedly connected between the positioning seat 52 and the flat plate 13; a second pulley is rotatably connected to the side of the positioning seat 52 away from the flat plate 13; during use, as the flat plate 13 moves upward, the flat plate 13 will drive the positioning seat 52 to move upward, and the second pulley rolls upward along the surface of the arc-shaped plate 54, so that the positioning seat 52 moves in the direction close to the vertical plate 51, causing the square tube on the flat plate 13 to slide. With the cooperation of the positioning seat 52 and the vertical plate 51, the position of the square tube is positioned, which can facilitate improving the accuracy of groove milling and is convenient for subsequent welding. When the length of the square tube is relatively long, after the positioning seat 52 fits with the square tube, the movement of the positioning seat 52 will cause the arc-shaped plate 54 to move backward, enabling the positioning seat 52 to continue to move upward normally. With this setting, the application range of this embodiment can be improved, and it is convenient to process square tubes of different lengths.

[0027] Furthermore, as Figure 1 and 6As shown in Fig. -7, a second bracket is fixedly connected to the side of the workbench 11; the second bracket is located on the side of the first bracket away from the arc-shaped plate 54; a first ring body 76 and a second ring body 77 are fixedly connected to the top of the vertical plate 51; the first ring body 76 is located in the middle of the second ring body 77; a cleaning electric push rod 71 is fixedly connected to the top of the second bracket; a fixed seat 72 is fixedly connected to the output end of the cleaning electric push rod 71; a plurality of pairs of elastic rods 73 are fixedly connected to the side of the fixed seat 72; a grinding plate 74 is fixedly connected to the end of the elastic rod 73 away from the fixed seat 72; an elastic hook 75 is fixedly connected to the side of each pair of elastic rods 73 away from each other; after milling is completed, the cleaning electric push rod 71 is started. The cleaning electric push rod 71 is initially in a contracted state. The cleaning electric push rod 71 will push the fixed seat 72 and the elastic rods 73 to move towards the square tube. The positions of the elastic hooks 75 correspond to those of the first ring body 76 and the second ring body 77. As it moves, the first ring body 76 and the second ring body 77 will be caught in the elastic hooks 75, causing the two mutually approaching elastic rods 73 to bend and open towards the mutually away side, so as to facilitate the insertion of the tube wall of the square tube between the two grinding plates 74. As it continues to be inserted, the elastic hooks 75 will bend and separate from the first ring body 76 and the second ring body 77, and the elastic rods 73 will drive the grinding plates 74 to clamp the square tube. The milling part of the square tube can be polished by relying on the grinding plates 74 to reduce burrs, so as to facilitate subsequent fitting and welding, reduce the influence of burrs on the welding quality, and at the same time, the above settings can facilitate the grinding of square tubes with different sizes and different thicknesses.

[0028] Further, as Figures 7-8As shown, on the side of the fixed seat 72 away from the cleaning electric push rod 71, a plurality of cleaning rods 81 are fixedly connected; on the surface of the cleaning rods 81, a plurality of cleaning hairs 82 are fixedly connected; both the cleaning hairs 82 and the cleaning rods 81 are made of elastic materials; at one end of the cleaning rod 81 away from the fixed seat 72, an elastic rope 83 is fixedly connected; at the end of the elastic rope 83, a pulling rope 84 is fixedly connected; a plurality of through holes are formed in the fixed seat 72; the pulling rope 84 passes through the through holes and its end is fixedly connected to the second bracket; a rubber ball 85 is fixedly connected to the pulling rope 84; the rubber ball 85 is located on the side of the fixed seat 72 close to the elastic rod 73; during use, the cleaning rod 81 will be inserted into the inside of the square tube as the fixed seat 72 moves. After being inserted to a certain depth, the pulling rope 84 will be tightened. The continuous movement of the cleaning rod 81 will cause the pulling rope 84 to pull the cleaning rod 81 to bend towards the square tube, so that the cleaning rod 81 and the cleaning hairs 82 open and block the inside of the square tube. At the same time, the rubber ball 85 will move through the through hole along with the pulling rope 84. When the fixed seat 72 pulls the cleaning rod 81 to reset, the opened cleaning rod 81 will pull out the iron filings milled and polished inside the square tube, thereby playing a role in cleaning the inside of the square tube, and reducing the influence of iron filings adhering to the welding surface on the welding effect during subsequent welding. Since the rubber ball 85 has a certain elasticity, after the fixed seat 72 resets, the rubber ball 85 blocks the side of the through hole, so that the cleaning rod 81 will not immediately recover, and it remains open and is pulled out from the square tube. After a certain period of time, the rubber ball 85 will deform and reset, causing the cleaning rod 81 to recover, and the resulting jitter will shake off the foreign objects on the cleaning rod 81, performing self-cleaning on it.

[0029] Further, as Figures 7-8 shown, a plurality of pull rings 61 are sleeved on the surface of the cleaning rod 81; the pull rings 61 are slidably connected to the cleaning rod 81; a plurality of connecting ropes 62 are fixedly connected to the pull rings 61; the connecting ropes 62 are fixedly connected to the end of the pulling rope 84; during use, the pulling of the connecting ropes 62 will cause the elastic rope 83 to stretch, and then pull the connecting ropes 62 to move, thereby pulling the pull rings 61 to move, so that the cleaning hairs 82 open, and thus the volume of the opened cleaning hairs 82 is larger, improving the fit between the cleaning hairs 82 and the square tube, and facilitating the cleaning of the square tube by the cleaning hairs 82.

[0030] Further, as Figure 2As shown in the figure, a blanking inclined plate 91 is fixedly connected to the side of the workbench 11 away from the longitudinal push hydraulic cylinder 18; a plurality of rollers 92 are rotatably connected to the bottom of the blanking inclined plate 91; during use, after the square tube is cleaned, it is pushed from the workbench 11 onto the blanking inclined plate 91 by the longitudinal push hydraulic cylinder 18, and the square tube slides off the blanking inclined plate 91. The blanking inclined plate 91 is inclined in the direction away from the machine head 15. Then, during the sliding process of the square tube, relying on the slightly upward convex rollers 92, one end of the square tube is lifted, so that the square tube vibrates back and forth during the sliding process, thereby shaking off some iron chips that have not been cleaned inside or on the surface of the square tube, improving the cleaning effect and the cleaning effect. Due to the insertion of the grinding plate 74 and the cleaning rod 81, some of the milled iron chips will be stabbed deep into the square tube, and these iron chips can be processed by this setting.

[0031] Further, as Figure 6 shown in the figure, a collection box 101 is fixedly connected to the bottom of the vertical plate 51; the collection box 101 is located at the bottom of the machine head 15; a shielding cover 102 is fixedly connected to the top of the vertical plate 51; during use, the collection box 101 can be used to collect the milled metal chips, so as to facilitate the staff to collect and process the chips. The shielding cover 102 is used for shielding and collecting, facilitating the chips to enter the interior of the collection box 101.

[0032] Further, it also includes a visual tracking sensor and a control host installed on the fixed frame: The visual tracking sensor can track the position of the square tube and transmit the visual image of the square tube to the control host: The milling head 15, the driving electric push rod 16, the lifting hydraulic cylinder 12, the longitudinal push hydraulic cylinder 18, and the cleaning electric push rod 71 are controlled by a servo system; During use, rely on the visual tracking sensor to track the processing position of the square tube and transmit the visual position data to the control host. The control host is used to control and process the data of the servo system, and the control host is adapted to an artificial intelligence algorithm. The control host controls the "milling head 15, the driving electric push rod 16, the lifting hydraulic cylinder 12, the longitudinal push hydraulic cylinder 18, and the cleaning electric push rod 71" to work according to the position of the square tube for automated processing.

[0033] Working principle: During use, the operator hangs the square pipe on the workbench 11, and then starts the longitudinal push hydraulic cylinder 18 to push the square pipe to move above the flat plate 13. The longitudinal push hydraulic cylinder 18 is in a contracted state initially. After the square pipe moves above the flat plate 13, the longitudinal push hydraulic cylinder 18 resets. Then, start the lifting hydraulic cylinder 12 to drive the flat plate 13 to move upward. The lifting hydraulic cylinder 12 is in a contracted state initially. Relying on the cooperation of the flat plate 13 and the fixed plate 14 to clamp and fix the square pipe. With the above settings, during the milling process, the square pipe is clamped and fixed, thereby reducing the influence of shaking on the milling accuracy during the milling process, further reducing the fitting degree of the groove and the pipe to be welded in the subsequent process, and thus reducing the influence on welding. Relying on the push of the driving electric push rod 16 to drive the cross bar 17, the hinge seat and the machine head 15 to move, so that the support rod 23 and the adjusting rod 22 rotate around the rotating connection of the moving seat 21, and then drive the milling cutter to rotate around the rotating connection of the moving seat 21 as the center, thereby completing the milling of the square pipe groove. During the production process, the sizes of the pipes to be welded are different, so the groove of the square pipe needs to be adjusted. At this time, the first screw 24 can be rotated to adjust the position of the moving seat 21, thereby adjusting the center point of the rotation of the milling cutter to adjust the groove. Then, rotate the second screw 25 to make the support rod 23 move in the opposite direction by the same length, and then make the milling cutter move back to its original position. With the above settings, the application range of the embodiment of the present invention can be improved, facilitating the milling of grooves of different sizes and convenient for the operator to use. The motor inside the machine head 15 fixes and installs the milling cutter through a chuck, and the motor inside the machine head 15 drives the milling cutter to rotate and mill; During use, as the flat plate 13 moves upward, the driving screw 35 is continuously withdrawn from the screw barrel 34, which can cause the screw barrel 34 and the gear 33 to rotate. The gear 33 is located between the first gear 33 and the second gear 33, which can drive the first rack, the second rack, the first moving frame 31 and the second moving frame 32 to approach each other, thereby driving the clamping plates 36 on both sides to approach each other, so as to fix the square tube and position the square tube, making the square tube move to the center position of the flat plate 13, which is convenient for subsequent milling and reduces the influence of misalignment on the milling accuracy, and is convenient for subsequent welding. During the upward movement of the flat plate 13, the first pulley 42 slides on the guide plate 41. The two sides of the guide plate 41 are designed in a Z-shaped structure, and the first pulley 42 slides upward along the inclined surface of the guide plate 41, causing the flip plate 43 to flip upward. The initial state of the flip plate 43 and the clamping plate 36 is parallel to the flat plate 13, and they are perpendicular to the flat plate 13 after flipping. This setting can reduce the situation of the clamping plate 36 blocking and facilitate the pushing of the square tube onto the flat plate 13. At the same time, the setting of the first spring can facilitate the adaptation to square tubes of different widths and improve the adaptation range. The torsion spring is used to reset the flip plate 43. As the flat plate 13 moves upward, the flat plate 13 will drive the positioning seat 52 to move upward, and the second pulley rolls upward along the surface of the arc plate 54, so that the positioning seat 52 moves toward the vertical plate 51, causing the square tube on the flat plate 13 to slide. With the cooperation of the positioning seat 52 and the vertical plate 51, the position of the square tube is positioned, which can facilitate the improvement of the bevel milling accuracy and is convenient for subsequent welding. When the length of the square tube is relatively long, after the positioning seat 52 fits with the square tube, the movement of the positioning seat 52 will cause the arc plate 54 to move backward, enabling the positioning seat 52 to continue to move upward normally. This setting can improve the application range of this embodiment and facilitate the processing of square tubes of different lengths; After milling is completed, start the cleaning electric push rod 71. The cleaning electric push rod 71 is initially in a contracted state. The cleaning electric push rod 71 will push the fixed seat 72 and the elastic rod 73 towards the square tube. The position of the elastic hook 75 corresponds to that of the first ring body 76 and the second ring body 77. With the movement, the first ring body 76 and the second ring body 77 will be caught in the elastic hook 75, causing the two mutually approaching elastic rods 73 to bend and open towards the mutually separated side, so as to facilitate the insertion of the tube wall of the square tube between the two grinding plates 74. With continuous insertion, the elastic hook 75 will bend and separate from the first ring body 76 and the second ring body 77, and the elastic rod 73 will drive the grinding plate 74 to clamp the square tube. The grinding plate 74 can be relied on to grind the milled part of the square tube, reduce burrs, so as to facilitate subsequent fitting and welding, and reduce the impact of burrs on the welding quality. At the same time, relying on the above settings can facilitate the grinding of square tubes with different sizes and different thicknesses. The cleaning rod 81 will be inserted into the interior of the square tube as the fixed seat 72 moves. After that, when it is inserted to a certain depth, the pull rope 84 will be tightened. The continuous movement of the cleaning rod 81 will cause the pull rope 84 to pull the cleaning rod 81 to bend towards the square tube, causing the cleaning rod 81 and the cleaning hair 82 to open and block the square tube. At the same time, the rubber ball 85 will move through the through hole as the pull rope 84 moves. When the fixed seat 72 pulls the cleaning rod 81 to reset, the opened cleaning rod 81 will pull out the iron filings milled and ground inside the square tube, so as to play a role in cleaning the interior of the square tube, thereby reducing the impact of iron filings adhering to the welding surface on the welding effect during subsequent welding. Since the rubber ball 85 has a certain elasticity, after the fixed seat 72 resets, the rubber ball 85 blocks the side of the through hole, so that the cleaning rod 81 will not immediately return to its original state, and it will be pulled out of the square tube while remaining open. After a certain period of time, the rubber ball 85 will deform and reset, causing the cleaning rod 81 to reset. The jitter generated by the reset will shake off the foreign objects on the cleaning rod 81 and perform self-cleaning. The pulling of the connecting rope 62 will cause the elastic rope 83 to stretch, and then pull the connecting rope 62 to move, thereby pulling the pull ring 61 to move, so as to open the cleaning hair 82, so that the volume of the opened cleaning hair 82 is larger, improving the fit degree of the cleaning hair 82 with the square tube and facilitating the cleaning of the square tube by the cleaning hair 82; After the square tube is cleaned, rely on the longitudinal push hydraulic cylinder 18 to push it from the workbench 11 onto the blanking inclined plate 91. The square tube slides down from the blanking inclined plate 91. The blanking inclined plate 91 is inclined in the direction away from the machine head 15. Then, during the sliding process of the square tube, rely on the slightly upward protruding roller 92 to lift one end of the square tube, causing the square tube to vibrate and bump back and forth during the sliding process, so as to shake off some iron filings that have not been cleaned inside or on the surface of the square tube, improving the cleaning effect and the cleaning effect. Rely on the setting of the collection box 101 to collect the milled metal debris, so as to facilitate the staff to collect and process the debris. The shielding cover 102 is used for shielding and collection, facilitating the debris to enter the interior of the collection box 101.
