DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 2As shown, an automatic pipe mouth chamfering machine according to an embodiment of the present invention comprises a workbench 1; a pair of symmetrically arranged moving seats are slidably connected to the top surface of the workbench 1, and both moving seats are driven by a servo motor; the two moving seats are rotatably connected to a rotating seat 2 on the side close to each other, and the rotating seat 2 is driven by a servo motor; a three-jaw chuck 3 is installed on the side close to each other of the two rotating seats 2; a tool head 4 is installed at the claws of the three-jaw chuck 3; an adjusting rod 5 is rotatably connected to the side surface of the three-jaw chuck 3; the adjusting rod 5 is embedded in the inside of the three-jaw chuck 3 and is used to adjust the claws on the three-jaw chuck 3; A pair of symmetrically arranged clamping seats 6 are installed on the top surface of the workbench 1 between the two moving seats; a pair of symmetrically arranged clamping plates 7 are slidably connected to the top surface of the clamping seats 6, and the clamping plates 7 are driven by a hydraulic system; the two clamping plates 7 are arranged in an arc shape on one side close to each other; a loading assembly is provided at the workbench 1; the loading assembly is used to transfer the pipe to be chamfered between the pair of clamping plates 7; the adjusting rod 5 drives the plane thread in the three-jaw chuck to rotate through gear meshing, thereby driving the jaws on the surface of the three-jaw chuck 3 to move; during work, in order to facilitate chamfering of pipes of different sizes, the present invention can be used For example, when chamfering pipes of different diameters, the user needs to first screw the adjusting rod 5 on the surface of the three-jaw chuck 3, and drive the claws on the surface of the three-jaw chuck 3 through the adjusting rod 5, and then the claws on the surface of the three-jaw chuck 3 drive the cutter head 4 toward or away from the center of the circle of the three-jaw chuck 3, thereby changing the spacing between each cutter head 4, and then ensuring that the cutter head 4 can correctly contact the pipe openings of pipes of different diameters. When the spacing between the cutter heads 4 is adjusted, the user can move the pipe to be chamfered to the clamping seat 6 through the feeding assembly. At this time, the hydraulic system will drive the two clamping plates 7 on the top surface of the clamping seat 6 to clamp each other. The two ends of the pipe are approached and clamped, and then the servo motor drives the movable seats on both sides to move toward the two ends of the pipe. At the same time, the rotating seat 2 drives the three-jaw chuck 3 to rotate, and then drives the cutter head 4 to rotate. When the cutter head 4 contacts the pipe mouth of the pipe, the cutter head 4 will complete the cutting of the pipe, thereby completing the chamfering operation of the pipe mouth at both ends of the pipe. The user adjusts the claws on the surface of the three-jaw chuck 3 through the adjusting rod 5, and then the claws drive the cutter head 4 to move, and then adjust the spacing between the cutter heads 4 to adapt to pipes of different diameters. Therefore, the user does not need to prepare multiple chamfering tools of different sizes, thereby reducing the user's cost.

[0023] like Figure 1 、 Figure 3 、 Figure 5 and Figure 6As shown, the top surface of the workbench 1 is provided with a pair of symmetrically arranged ejection holes 8; a driving rod 9 is provided inside the ejection hole 8; the top of the driving rod 9 is provided in a hexagonal prism; the end of the adjusting rod 5 facing the outside of the three-jaw chuck 3 is provided with a groove 10, and the groove 10 is adapted to the top of the driving rod 9; the bottom surfaces of the two driving rods 9 are connected to a connecting plate 11 for common rotation, and the connecting plate 11 is slidably connected to the inside of the workbench 1; the two driving rods 9 are connected by a chain and driven by a servo motor; when working, when the user needs to rotate the adjusting rod 5, the user can drive the two The moving seats move away from each other, so that the three-jaw chuck 3 moves to the ejection hole 8, and then the user rotates the three-jaw chuck 3 so that the adjustment rod 5 on the surface of the three-jaw chuck 3 faces the ejection hole 8. Then the user lifts the connecting plate 11, and the connecting plate 11 drives the driving rod 9 to eject the ejection hole 8, and finally the top hexagonal prism of the driving rod 9 is inserted into the groove 10 on the end face of the adjusting rod 5, so that the two are spliced ​​together and can rotate synchronously. Then the servo motor drives the two driving rods 9 to rotate in the same direction at the same time through the chain, thereby realizing the synchronous adjustment of the three-jaw chucks 3 on both sides, thereby ensuring that the chamfering effect at both ends of the pipe is consistent.

[0024] like Figures 4 to 6As shown, the movable seat includes a receiving seat 12 and a driving seat 13; the rotating seat 2 rotates on the side of the receiving seat 12 away from the driving seat 13; the top surface of the workbench 1 is provided with guide grooves 14 at both sides; the bottom surface of the driving seat 13 is rotatably connected to the plug plate 15; the rotating connection between the plug plate 15 and the driving seat 13 is installed with a torsion spring, and the plug plate 15 is L-shaped; the bottom surface of the receiving seat 12 is provided with a slot 27; the bottom of the driving seat 13 is fixedly connected to the connecting frame 16; the bottom of the connecting frame 16 is slidably connected to the workbench 1 The interior of the workbench 1 is fixedly connected to a connecting pipe 17 on the side away from each other of the two connecting frames 16, and the connecting pipe 17 is set in an L shape; both ends of the connecting pipe 17 are slidably connected to the extrusion rod 18; when working, when chamfering the pipe, one end of the inserting plate 15 is inserted into the slot 27, and the driving seat 13 can drive the receiving seat 12 to move together, and when the user needs to rotate the adjusting rod 5, the user needs to control the driving seat 13 to move the receiving seat 12 toward the guide groove 14, and when the inserting plate 15 moves to the guide groove 14, the inserting plate 15 will Driven by the torsion spring, it disengages from the slot 27. At this time, the three-jaw chuck 3 at the end of the receiving seat 12 will be at the ejection hole 8, and then the driving seat 13 will continue to move in the direction of the guide groove 14, but at this time the receiving seat 12 will no longer move with the driving seat 13. During the movement of the driving seat 13, the driving seat 13 will drive the connecting frame 16 to squeeze the extrusion rod 18 at the bottom of the connecting tube 17, and then lift the extrusion rod 18 at the top of the connecting tube 17, thereby lifting the connecting plate 11, and finally allowing the driving rod 9 on the top surface of the connecting plate 11 to be inserted into the groove 10 at the end of the adjusting rod 5. When the three-jaw chuck 3 is adjusted, the driving seat 13 drives the connecting frame 16 to move toward the middle of the workbench 1. When the connecting frame 16 no longer squeezes the bottom squeezing rod 18, the top squeezing rod 18 will be reset under the action of the gravity of the connecting plate 11 and the driving rod 9. When the inserting plate 15 passes through the guide groove 14, the inserting plate 15 will also be squeezed and inserted into the slot 27, so that the receiving seat 12 and the driving seat 13 are combined together again, and the subsequent pipe chamfering operation can be carried out normally.

[0025] like Figure 4 and Figure 7 As shown, a rotation groove 19 is provided at the bending portion of the plug board 15; a rotation roller 20 is rotatably connected in the rotation groove 19; during operation, when the plug board 15 passes through the guide groove 14, the rotation roller 20 in the rotation groove 19 on the surface of the plug board 15 will contact the bottom of the guide groove 14, thereby reducing the friction force of the plug board 15 when moving in the guide groove 14, thereby reducing the wear of the plug board 15 and increasing the service life of the plug board 15.

[0026] like Figure 1 and Figure 5As shown, the loading assembly includes a support frame 21; the workbench 1 is located on the bottom surface of the support frame 21; the top of the support frame 21 is slidably connected to a movable plate 22, and the movable plate 22 is driven by a driving assembly; the bottom surface of the movable plate 22 is fixedly connected to hydraulic rods 23 at both ends; the telescopic end of the hydraulic rod 23 is equipped with a clamping claw 24, and the clamping claw 24 is driven by a hydraulic system; during operation, when loading is required, the movable plate 22 on the support frame 21 will first move to the pipe to be chamfered, and the other chamfer is located directly above the clamping seat 6, and then the two hydraulic rods 23 drive the clamping claw 24 to descend, and the clamping claw 24 at one end clamps the pipe to be chamfered, and then the hydraulic rod 23 rises and moves The movable plate 22 is reset so that the clamping jaws 24 holding the pipe are located on the top of the clamping seat 6, and then the hydraulic rod 23 descends to place the pipe to be chamfered between the two clamping plates 7. When the pipe to be chamfered is chamfered, the previous operation of clamping the pipe to be chamfered is repeated. However, while one clamping jaw 24 clamps the pipe to be chamfered, the other clamping jaw 24 can clamp the pipe that has been chamfered. When the movable plate 22 drives the clamping jaws 24 to move the new pipe to be chamfered to the clamping seat 6, the other clamping jaw 24 also moves the chamfered pipe out of the top surface of the workbench 1, thereby completing the loading and unloading operations, thereby eliminating the need for the user to manually load and unload, further reducing the usability of the embodiment of the present invention.

[0027] like Figure 1 、 Figure 5 and Figure 6 As shown, the driving assembly includes a rotating rod 25; the rotating rod 25 is rotatably connected to the workbench 1, and the rotating rod 25 extends to the outside of the workbench 1; a toothed plate 26 is fixedly connected to the bottom surface of the connecting frame 16 near the rotating rod 25; a gear 28 is fixedly connected to the surface of the rotating rod 25 at the corresponding position of the toothed plate 26, and the gear 28 is meshed with the toothed plate 26; a sleeve 29 is threadedly connected to the surface of the rotating rod 25; a transmission plate 30 is fixedly connected between the sleeve 29 and the movable plate 22; during operation, when the two driving seats 13 approach or move away from each other, the driving seat will synchronously drive the toothed plate 26 to move through the connecting plate 11, and the toothed plate 26 will drive the gear 28 meshing with it to rotate, and the gear 28 will drive the rotating rod 25 to rotate, and the rotating rod 25 will finally drive the movable plate 22 to move through the sleeve 29 on its surface, thereby eliminating the need to add an additional power source, thereby reducing the cost of the embodiment of the present invention.

[0028] like Figure 1 and Figure 8The loading platform 31 is fixedly connected to one side of the workbench 1, and the top surface of the loading platform 31 is recessed at the corresponding position of the clamping jaws 24; the top surface of the loading platform 31 is inclined; the top surface of the loading platform 31 is provided with a pair of ejection grooves 32; the ejection grooves 32 are slidably connected with ejection blocks 33; the ejection blocks 33 are driven by a hydraulic system; the loading platform 31 is fixedly connected to a guide plate 34 on the side away from the workbench 1; the guide plate 34 is inclined; during work, in order to further facilitate loading, the user can transfer the pipe to be chamfered to the guide plate 34 through the conveyor belt, and the guide plate 34 will guide the pipe to the side of the loading platform 31 close to the ejection groove 32, and then the ejection block 33 in the ejection groove 32 is lifted, thereby pushing a pipe at the guide plate to the loading platform 31, thereby facilitating the clamping of the clamping jaws 24 and avoiding the pipes from piling up and affecting the clamping of the clamping jaws 24.

[0029] like Figure 8 As shown, a partition plate 35 is provided on the top surface of the ejection block 33; the partition plate 35 is made of a magnet; the ejection block 33 is made of a magnetizable metal; the cross-section of the partition plate 35 is triangular; during operation, when processing pipes of different diameters, the user can adjust the position of the partition plate 35 on the top surface of the ejection block 33 so that the ejection block can only lift one pipe to the loading platform 31 at a time, thereby improving the scope of application of the embodiment of the present invention.

[0030] like Figure 1 and Figure 9 As shown, a bottom plate 36 is fixedly connected to the side where the two receiving seats 12 are close to each other; a baffle 37 is fixedly connected to the side where the baffle 37 is away from the receiving seat 12; the top of the baffle 37 is arc-shaped; during operation, when the cutter head 4 chamfers the pipe, the bottom plate 36 and the baffle 37 can shield the debris, preventing the debris from splashing everywhere, which is not conducive to cleaning by the user.

[0031] like Figure 9 As shown, the side of the base plate 36 close to the three-jaw chuck 3 is fixedly connected to an air guide tube 38, and the air guide tube 38 is arranged in a ring shape; the side of the air guide tube 38 close to the three-jaw chuck 3 is provided with an air guide groove 39; both sides of the baffle 37 are fixedly connected with a conduit 40; the conduit 40 is connected to the air guide tube 38, and the conduit 40 is connected to an external air pump; when working, in the process of chamfering the pipe, the external air pump will pump air into the air guide tube 38 through the conduit 40, and then the gas will be blown to the three-jaw chuck 3 through the air guide groove 39 on the surface of the air guide tube 38, thereby preventing debris from entering the interior of the three-jaw chuck 3, causing the jaws on the surface of the three-jaw chuck 3 to move poorly.

[0032] During operation, in order to facilitate chamfering of pipes of different sizes, the embodiment of the present invention can be used. When chamfering pipes of different diameters, the user needs to first screw the adjusting rod 5 on the surface of the three-jaw chuck 3, and drive the claws on the surface of the three-jaw chuck 3 through the adjusting rod 5, and then the claws on the surface of the three-jaw chuck 3 drive the cutter head 4 toward or away from the center of the circle of the three-jaw chuck 3, thereby changing the spacing between each cutter head 4, and then ensuring that the cutter head 4 can correctly contact the pipe openings of pipes of different diameters. When the spacing between the cutter heads 4 is adjusted, the user can move the pipe to be chamfered to the clamping seat 6 through the loading assembly. At this time, the hydraulic system will drive the clamping The two clamping plates 7 on the top surface of the seat 6 are close to each other, thereby clamping the two ends of the pipe. Then the servo motor drives the movable seats on both sides to move toward the two ends of the pipe. At the same time, the rotating seat 2 drives the three-jaw chuck 3 to rotate, and then drives the cutter head 4 to rotate. When the cutter head 4 contacts the pipe mouth of the pipe, the cutter head 4 will complete the cutting of the pipe, thereby completing the chamfering operation of the pipe mouth at both ends of the pipe. The user adjusts the claws on the surface of the three-jaw chuck 3 through the adjusting rod 5, and then the claws drive the cutter head 4 to move, and then adjust the spacing between the cutter heads 4 to adapt to pipes of different diameters. Therefore, the user does not need to prepare multiple chamfering tools of different sizes, thereby reducing the user's cost.

[0033] When the user needs to rotate the adjusting rod 5, the user can drive the two moving seats away from each other, so that the three-jaw chuck 3 moves to the ejection hole 8, and then the user rotates the three-jaw chuck 3 so that the adjusting rod 5 on the surface of the three-jaw chuck 3 faces the ejection hole 8, and then the user lifts the connecting plate 11, and the connecting plate 11 drives the driving rod 9 to eject the ejection hole 8, and finally the top hexagonal prism of the driving rod 9 is inserted into the groove 10 on the end face of the adjusting rod 5, so that the two are spliced ​​together and can rotate synchronously, and then the servo motor drives the two driving rods 9 to rotate in the same direction at the same time through the chain, thereby realizing the synchronous adjustment of the three-jaw chucks 3 on both sides, thereby ensuring that the chamfering effect at both ends of the pipe is consistent.

[0034] When the pipe is chamfered, one end of the inserting plate 15 is inserted into the slot 27. At this time, the driving seat 13 can drive the receiving seat 12 to move together. When the user needs to rotate the adjusting rod 5, the user needs to control the driving seat 13 to move the receiving seat 12 toward the guide groove 14. When the inserting plate 15 moves to the guide groove 14, the inserting plate 15 will be driven by the torsion spring to disengage from the slot 27. At this time, the three-jaw chuck 3 at the end of the receiving seat 12 will be at the ejection hole 8, and then the driving seat 13 continues to move in the direction of the guide groove 14, but at this time the receiving seat 12 will no longer move with the driving seat 13. In the process of moving the driving seat 13, the driving seat 13 will drive the connecting frame 16 to squeeze the extrusion rod 18 at the bottom of the connecting pipe 17, thereby connecting The squeezing rod 18 at the top of the connecting pipe 17 is lifted up, thereby lifting the connecting plate 11, and finally allowing the driving rod 9 on the top surface of the connecting plate 11 to be inserted into the groove 10 at the end of the adjusting rod 5, thereby eliminating the need for the user to manually lift the connecting plate 11, thereby reducing the difficulty of operation. After the three-jaw chuck 3 is adjusted, the driving seat 13 drives the connecting frame 16 to move toward the middle of the workbench 1. When the connecting frame 16 no longer squeezes the bottom squeezing rod 18, the top squeezing rod 18 will be reset under the action of the gravity of the connecting plate 11 and the driving rod 9, and when the inserting plate 15 passes through the guide groove 14, the inserting plate 15 will also be squeezed and inserted into the slot 27, so that the receiving seat 12 and the driving seat 13 are combined together again, and the subsequent pipe chamfering operation can be carried out normally.

[0035] When the plugboard 15 passes through the guide groove 14, the rotating roller 20 in the rotating groove 19 on the surface of the plugboard 15 will contact the bottom of the guide groove 14, thereby reducing the friction of the plugboard 15 when moving in the guide groove 14, thereby reducing the wear of the plugboard 15 and increasing the service life of the plugboard 15.

[0036] When loading is required, the movable plate 22 on the support frame 21 will first move to the pipe to be chamfered, and the other chamfer is located just above the clamping seat 6, and then the two hydraulic rods 23 drive the clamping claws 24 to descend, and the clamping claws 24 at one end clamp the pipe to be chamfered, then the hydraulic rod 23 rises, and the movable plate 22 is reset, so that the clamping claws 24 with the pipe are located at the top of the clamping seat 6, and then the hydraulic rod 23 descends, and the pipe to be chamfered is placed between the two clamping plates 7. After the corner is completed, the previous operation of clamping the pipe to be chamfered is repeated, but while one clamping jaw 24 clamps the pipe to be chamfered, the other clamping jaw 24 can clamp the pipe that has been chamfered. When the movable plate 22 drives the clamping jaw 24 to move the new pipe to be chamfered to the clamping seat 6, the other clamping jaw 24 also moves the chamfered pipe out of the top surface of the workbench 1, thereby completing the two operations of loading and unloading, so that the user does not need to manually load and unload, further reducing the usability of the embodiment of the present invention.

[0037] When the two drive seats 13 approach or move away from each other, the drive seats will synchronously drive the tooth plate 26 to move through the connecting plate 11, and the tooth plate 26 will drive the gear 28 engaged with it to rotate, and the gear 28 will drive the rotating rod 25 to rotate, and the rotating rod 25 will finally drive the moving plate 22 to move through the sleeve 29 on its surface, thereby eliminating the need to add an additional power source, thereby reducing the cost of the embodiment of the present invention.

[0038] To further facilitate loading, the user can use a conveyor belt to transfer the pipe to be chamfered to the guide plate 34. The guide plate 34 will guide the pipe to the side of the loading platform 31 close to the ejection groove 32. Then the ejection block 33 in the ejection groove 32 will be lifted, thereby pushing a pipe at the guide plate to the loading platform 31, thereby facilitating the clamping of the clamp 24 and preventing the pipes from piling up, which affects the clamping of the clamp 24.

[0039] When processing pipes of different diameters, the user can adjust the position of the partition plate 35 on the top surface of the ejection block 33 so that the ejection block can only lift one pipe to the loading platform 31 at a time, thereby improving the scope of application of the embodiment of the present invention.

[0040] When the cutter head 4 is chamfering the pipe, the bottom plate 36 and the baffle 37 can shield the debris, thereby preventing the debris from scattering everywhere and making it difficult for the user to clean it.

[0041] During the process of chamfering the pipe, an external air pump will pump air into the air guide tube 38 through the conduit 40, and then the air guide groove 39 on the surface of the air guide tube 38 will blow the gas toward the three-jaw chuck 3, thereby preventing debris from entering the interior of the three-jaw chuck 3 and causing the jaws on the surface of the three-jaw chuck 3 to move poorly.

[0042] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
