Detailed implementation

[0027] The present utility model provides a three-chuck bevel pipe cutting device. To make the purpose, technical solution and effects of the present utility model clearer and more definite, the following further elaborates on the present utility model by way of examples with reference to the accompanying drawings. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0028] Please refer to Figure 1 and Figure 2, the present utility model provides a three-chuck bevel pipe cutting device, which includes a side-mounted bed 1 composed of a first sub-frame 111 and a second sub-frame 112 spliced together, a gantry 13 arranged on the second sub-frame 112, a laser cutting assembly 3 arranged on the gantry 13 and displaceable along the x-axis, z-axis and A-axis, a first chuck structure 71, a second chuck structure 72 and a third chuck structure 73 slidably arranged on the side-mounted bed 1 in sequence from back to front, a loading mechanism 8 arranged beside the first sub-frame 111, and a receiving mechanism 9 arranged beside the second sub-frame 112; a plurality of mounting side seats 16 are fixedly connected beside the first sub-frame 111, and a centering support mechanism 5 is arranged on some of the mounting side seats 16, and the centering support mechanism 5 is used for centering and supporting the pipe.

[0029] In practical applications, the pipe is orderly transported above the centering support mechanism 5 through the loading mechanism 8, and then the centering support mechanism 5 centers and positions the pipe and lifts the pipe to be coaxial with the first chuck structure 71, the second chuck structure 72 and the third chuck structure 73. The pipe will be clamped by the first chuck structure 71 and the second chuck structure 72 and the pipe is pushed forward by the first chuck structure 71 towards the laser cutting assembly 3 to achieve cutting feed. The cut pipe section will be clamped by the third chuck structure 73 for blanking. Since the laser cutting assembly 3 can move in multiple axes, it can not only perform straight cutting on the pipe but also perform bevel cutting on the pipe. The cut pipe section is received by the receiving mechanism 9 and slides into the finished product storage rack 90 to achieve blanking. It can be understood that the second chuck structure 72 can move relative to the laser cutting assembly 3. When there is remaining tail material of the pipe, the A-axis turntable 38 controls the laser cutting head 39 to be vertically downward, reduces the distance between the second chuck structure 72 and the laser cutting assembly 3, and then straight cuts the remaining pipe, thereby reducing the amount of tail material.

[0030] In practical applications, two three-chuck bevel pipe cutting devices are arranged in a mirror-symmetrical manner. The mirror-symmetrical arrangement allows the devices to be arranged closely, which can significantly reduce the floor area of the production line. Especially in a factory building with limited space, this layout can make more effective use of the available space. The operator can monitor and control the two devices without moving significantly, which simplifies the operation process, reduces the physical consumption of the operator, and improves the work efficiency.

[0031] Specifically, see Figure 1 and Figure 8As shown in the figure, the feeding mechanism 8 includes two feeding components 81 and a supporting component 82 disposed between the two feeding components 81. The feeding component 81 includes a first frame 811, a first sprocket 812 rotatably disposed on the frame, a second sprocket 813, and a transport chain 814 wound around the first sprocket 812 and the second sprocket 813. A plurality of material limiting blocks 815 are provided on the outer side surface of the transport chain 814, and a material storage bayonet 816 is formed between two adjacent material limiting blocks 815. The first sprockets 812 on the two feeding components 81 are drivingly connected through a transmission shaft 83, and the transmission shaft 83 is drivingly connected to a rotation driving device 84; the supporting component 82 includes a second frame 821 and a smooth shaft 822 fixed on the second frame 821, and the smooth shaft 822 extends along the pipe conveying direction; one leg of the first frame 811 and the second frame 821 is fixedly connected to the corresponding mounting side seat 16, and the other leg of the first frame 811 and the second frame 821 is placed on the ground.

[0032] In other words, the first frame 811 and the second frame 821 are in an L-shaped structure, that is, one leg of the first frame 811 on the feeding component 81 is shorter and is fixed to the mounting side seat 16 by screws, and the other leg is in contact with the ground through a height-adjusting foot cup. One leg of the second frame 821 is shorter and is fixed to the mounting side seat 16 by screws, and the other leg of the second frame 821 is in contact with the ground through a height-adjusting foot cup. Similarly, the rotation driving device 84 is also fixed to the mounting side seat 16. It can be understood that a discharging station is provided at a position of the transport chain 814 close to the second sprocket 813, and a feeding station is provided at a position of the transport chain 814 close to the first sprocket 812. The pipe fittings placed at the discharging station move towards the feeding station along with the movement of the transport chain 814.

[0033] During feeding, the pipe fittings are placed horizontally and extend transversely. After the pipe fittings are placed at the discharging station, the two ends of the pipe fittings are clamped in the material storage bayonets 816 of the two transport chains 814. Driven by the rotation driving device 84, the transport chains 814 of the two feeding components 81 move synchronously, driving the pipe fittings to be transported forward; at the same time, the middle part of the pipe fittings is supported by the smooth shaft 822 to prevent the middle part of the pipe fittings from bending and sagging. Since the surface of the smooth shaft 822 is chrome-plated, the surface is smooth and has high hardness, and the friction between the pipe fittings and the smooth shaft 822 is small, which will not cause damage to the pipe fittings. Whenever a pipe fitting is transported to the feeding station, the transport chains 814 of the two feeding components 81 stop moving and wait for the centering and supporting mechanism to lift the pipe fitting so that the pipe fitting is separated from the feeding rack.

[0034] The three-chuck bevel pipe cutting equipment provided by the utility model, on the one hand, designs the bed body as a side-mounted bed body 1 composed of a first sub-frame 111 and a second sub-frame 112 spliced together. On the other hand, the feeding mechanism 8 is designed in a simplified manner and is connected and fixed by means of the installation side seat 16, so that the overall width is reduced, and the space can be effectively utilized even in a factory building with limited area, which is beneficial to the arrangement of multiple devices, thereby improving the flexibility of the production layout.

[0035] In order to be able to adjust the tightness of the transport chain 814, the second sprocket 813 is arranged on the adjustment support shaft 817 through a bearing. Stopping planes are provided on the peripheral walls at both ends of the adjustment support shaft 817, and tensioning threaded holes are provided on the stopping planes. Two fixing blocks 818 are arranged on the first frame 811. A tensioning screw 819 that cooperates with the tensioning threaded hole passes through each fixing block 818. The head of the tensioning screw 819 presses against the fixing block 818, and the screw part of the tensioning screw 819 is connected to the tensioning threaded hole; by turning the head of the tensioning screw 819, the front and rear positions of the adjustment support shaft 817 can be finely adjusted, so that the transport chain 814 obtains an appropriate tensioning force. In order to prevent the tensioning screw 819 from loosening due to resonance during long-term operation, two locking nuts are assembled on the tensioning screw 819. One of the locking nuts presses against the stopping plane of the adjustment support shaft 817, and the other locking nut and the head of the tensioning screw 819 jointly clamp the fixing block 818.

[0036] Preferably, as shown in Figure 8 shown, the first sprocket 812 is sleeved on the rotating shaft 810. The rotating shaft 810 is connected to the first frame 811 through two pedestal bearings. One end of the rotating shaft 810 is connected to the transmission shaft 83 through a universal joint coupling 8101. In other words, when one of the rotating shafts 810 rotates, the power is sequentially transmitted to the other rotating shaft 810 through the universal joint coupling 8101, the transmission shaft 83, and the universal joint coupling 8101. The universal joint coupling 8101 can compensate for the misalignment problem caused by a certain angular deviation or displacement between the axes of the two rotating shafts 810, so that the two rotating shafts 810 can be kept connected to each other and transmit torque, reducing the strict requirements for axis pairing.

[0037] Preferably, the rotation driving device 84 is specifically that the feeding driving motor drives the rotating shaft 810 to rotate through a synchronous belt transmission structure or a chain transmission structure, and then drives the first sprocket 812 on the rotating shaft 810 to rotate, providing power for the transport chain 814.

[0038] To prevent the transport chain 814 from still driving the pipe forward due to control failure after the pipe is transported to the loading station, resulting in the pipe fitting falling from the transport chain 814 to the ground and being damaged, a baffle plate 85 for blocking the continuous forward conveyance of the pipe is provided on the side of the first rack 811, and an in-stroke sensing mechanism 86 for sensing the pipe is provided upstream of the baffle plate 85 and a loading station is provided.

[0039] Specifically, the in-stroke sensing mechanism 86 includes a support plate fixed to the first rack 811, a travel switch provided on the support plate, and a pressure plate provided at the output end of the travel switch. When the transport chain 814 drives the pipe fitting to approach the loading station, the pipe fitting slides into the center of the pressure plate, and the weight of the pipe fitting causes the pressure plate to turn over, thereby triggering the travel switch, causing the travel switch to feedback to the control system. The control system controls the rotation drive device 84 to stop working, so that the pipe just displaces to the loading station.

[0040] In this embodiment, see Figure 6 and Figure 7 As shown, both the first sub-rack 111 and the second sub-rack 112 include a group of horizontal pipes 14 stacked and fixedly connected by multiple horizontal pipes, and a reinforcing frame 15 provided behind the group of horizontal pipes 14. By setting it like this, the bed body is designed with light weight, adapts to the rapid manufacturing rhythm, and has good structural stability.

[0041] Specifically, see Figure 6 and Figure 7 As shown, an installation sealing plate 123 is provided at the connection end of the first sub-rack 111 and the second sub-rack 112, and a decorative sealing plate 124 is provided at the non-connection end of the first sub-rack 111 and the second sub-rack 112. The corresponding installation sealing plates 123 of the first sub-rack 111 and the second sub-rack 112 are connected by bolts. The installation surface of the installation sealing plate 123 is processed by precision machining to improve the splicing accuracy of the first sub-rack 111 and the second sub-rack 112, and thus ensure the straightness of the side-mounted bed body 1.

[0042] Furthermore, see Figure 6 and Figure 7 As shown, the reinforcing frame 15 includes a reinforcing upper cross beam 151, a reinforcing lower cross beam 152 provided below the reinforcing upper cross beam 151, and a plurality of connecting vertical beams 153 connecting the reinforcing upper cross beam 151 and the reinforcing lower cross beam 152. The reinforcing upper cross beam 151, the reinforcing lower cross beam 152 and the connecting vertical beams 153 together form a more stable frame structure, significantly enhancing the rigidity and anti-deformation ability of the entire side-mounted bed body 1.

[0043] The top surface of the reinforced upper crossbeam 151 can be used as the support surface of the Y-axis drag chain, and the reinforced upper crossbeam 151 supports the movement of the Y-axis drag chain. The bottom of the connecting vertical beam 153 is provided with a wiring notch 154 near the horizontal tube group 14. The wiring notch 154 design provides a convenient wiring channel, standardizes the line direction, is beautiful and improves safety, and also simplifies the maintenance and repair process.

[0044] In the above, the transverse tubes on the transverse tube group 14, the reinforced upper transverse beam 151, the reinforced lower transverse beam 152, and the connecting vertical beam 153 are all made of rectangular steel tubes or square steel tubes, which have sufficient structural strength and rigidity. The various components in the first subframe 111 and the second subframe 112 are fixed by welding, and the overall structural strength is good.

[0045] In this embodiment, the transverse tube group 14 of the second sub-frame 112 is provided with an exhaust dust removal port 121 near the laser cutting assembly 3. The exhaust dust removal port 121 is provided with an inner sealing plate 122 that is separated from the interior of the transverse tube. The inner sealing plate 122 ensures that the exhaust airflow is concentrated on the exhaust dust removal port 121, and avoids the exhaust airflow entering the interior of the transverse tube to cause airflow dispersion, thereby enhancing the efficiency of the exhaust system and more efficiently extracting the dust generated during the cutting process. In fact, the exhaust dust removal port 121 works with the exhaust dust removal mechanism, so that the exhaust dust removal port 121 has a negative pressure exhaust capability. During the cutting process, when the exhaust dust removal mechanism is started, the airflow in the cutting area is sucked into the exhaust dust removal port 121 by negative pressure, thereby sucking the metal dust generated during the laser cutting process, effectively reducing the spread of dust in the workshop, improving the working environment, and protecting the health of operators.

[0046] See Figure 1 As shown, a first Y-axis guide rail 21 and a Y-axis rack 22 are provided on the top surface of the side-mounted bed 1 , and a second Y-axis guide rail 23 is provided on a side surface of the side-mounted bed 1 .

[0047] The first chuck structure 71 includes a first side hanging plate 711, a first chuck body 712 provided on the first side hanging plate 711, and a first Y-axis driving motor 713. A first Y-axis gear meshing with the Y-axis rack 22 is provided at the output end of the first Y-axis driving motor 713. The first side hanging plate 711 is slidably connected to the first Y-axis guide rail 21 and the second Y-axis guide rail 23 through Y-axis sliders respectively. Similarly, the second chuck structure 72 includes a second side hanging plate 721, a second chuck body 722 provided on the second side hanging plate 721, and a second Y-axis driving motor 723. A second Y-axis gear meshing with the Y-axis rack 22 is provided at the output end of the second Y-axis driving motor 723. The second side hanging plate 721 is slidably connected to the first Y-axis guide rail 21 and the second Y-axis guide rail 23 through Y-axis sliders respectively. Similarly, the third chuck structure 73 includes a third side hanging plate 731, a third chuck body 732 provided on the third side hanging plate 731, and a third Y-axis driving motor 733. A second Y-axis gear meshing with the Y-axis rack 22 is provided at the output end of the third Y-axis driving motor 733. The third side hanging plate 731 is slidably connected to the first Y-axis guide rail 21 and the second Y-axis guide rail 23 through Y-axis sliders respectively.

[0048] Specifically, the laser cutting assembly 3 includes an X-axis slide table 31 slidably provided on the gantry 13, an X-axis driving mechanism for driving the X-axis slide table 31 to move along the X-axis direction, a Z-axis slide table 35 slidably provided on the X-axis slide table 31, a Z-axis driving mechanism for driving the Z-axis slide table 35 to move along the Z-axis direction, an A-axis turntable 38 provided at the lower end of the Z-axis slide table 35, and a laser cutting head 39 mounted on the A-axis turntable 38. Under the control of the A-axis turntable 38, the laser cutting head 39 rotates within the range of ±45° to change the cutting angle, so that the laser cutting head 39 can not only perform straight cutting on the pipe but also perform bevel cutting on the pipe, and precise positioning and cutting of the laser cutting head 39 in the three-dimensional space are realized by combining the driving of the X-axis driving mechanism and the Z-axis driving mechanism.

[0049] The centering support mechanism 5 includes a fixed vertical plate 51 fixed on the installation side seat 16, a lifting slide plate 52 slidably provided on the fixed vertical plate 51, a lifting driving mechanism 55 for driving the lifting slide plate 52 to move up and down, and a clamping and positioning mechanism 56 provided on the lifting slide plate 52. The clamping and positioning mechanism 56 is used to clamp the pipe to a set position for positioning. Two supports 53 are provided at the top of the lifting slide plate 52, and the two supports 53 jointly support a horizontally extending and rotatable support roller 54.

[0050] After the loading mechanism 8 automatically transports the pipe to the support roller 54, the support roller 54 supports the pipe. The clamping and positioning mechanism 56 first clamps the pipe to the middle of the support roller 54, and then the lifting drive mechanism 55 lifts the pipe to a set height, making the pipe coaxial with the first chuck structure 71, the second chuck structure 72, and the third chuck structure 73, so that the first chuck structure 71 and the second chuck structure 72 can clamp the pipe. During the processing, the support roller 54 follows and supports the pipe fitting. When the pipe needs to rotate or interfere with the movement of the first chuck structure 71, the lifting drive mechanism 55 controls the components on the lifting slide plate 52 to descend for avoidance.
