Description

Technical Field

[0001] This utility model relates to the field of pipe positioning technology, and in particular to a pipe positioning device for a multi-axis pipe bending machine. Background Technology

[0002] The pipe positioning device of a multi-axis pipe bending machine is a mechanical device used to precisely fix and position pipes on the machine. Its main function is to ensure that the pipe maintains the correct position and angle during bending, achieving high-precision bending operations. Through a high-precision clamping, guiding, rotating, and detection system, it ensures the precise position and angle of the pipe during bending, improving production efficiency and product quality. It is a key component ensuring the accuracy of the pipe's position and angle during bending.

[0003] Existing bending machines typically have a bending die at the front end for positioning and bending the tube. Since the dimensions of the tube being bent have significant requirements for the bending die, multiple bending components are usually fixed together. The tube is positioned and bent by adjusting the position of the bending components. The production of multiple bending components increases the production cost of the device. At the same time, the installation of the bending components is relatively complex, and when it is necessary to disassemble and replace the bending components, it affects the operation of the workers and reduces the bending efficiency of the device for the tube.

[0007] By adopting the above technical solution, the slide rail provides moving support for the slide block.

[0008] A further feature of this invention is that the bottom of the slide block has a groove of a corresponding size corresponding to the positions of the two slide rails.

[0009] By adopting the above technical solution, the slide rail and slide groove can provide guiding and moving support for the slide block.

[0010] A further feature of this invention is that a fixing block is fixed to the top of the slide block by bolts, and a clamping limiting plate is provided on the front side of the fixing block.

[0011] By adopting the above technical solution, the bending tube can be limited by contacting one side of the inverted clamping limiting plate, thus avoiding deformation caused by bending force at the front end of the bending tube.

[0012] A further feature of this invention is that a first motor is provided inside one side of the movable seat, and a mounting bracket is provided on one side of the movable seat, with the upper and lower ends of one end of the mounting bracket being movably connected to the movable seat.

[0013] By adopting the above technical solution, the mounting bracket can rotate with the end movably connected to the movable seat as the center.

[0014] A further feature of this invention is that: the top end of the first motor passes through the mounting bracket and is movably connected to a first grinding wheel via a bearing; a second grinding wheel is provided on the top of the first grinding wheel; a second motor is fixed to the top of the second grinding wheel via bolts; and a lead screw is movably connected to the bottom end of the second motor through the second grinding wheel via a bearing. The bottom end of the lead screw is threadedly connected to the inside of the first grinding wheel.

[0015] By adopting the above technical solution, the second motor can drive the lead screw to rotate, and while the lead screw rotates, it can drive the second grinding wheel and the second motor to move up and down through the threaded connection with the first grinding wheel.

[0016] A further feature of this invention is that two fixed sliding rods are provided on both sides of the first grinding wheel, the top of the fixed sliding rods is slidably connected to the second grinding wheel, and a second limiting spring is sleeved on the outer side of the fixed sliding rods, with the two ends of the second limiting spring being fixedly connected to the first grinding wheel and the second grinding wheel, respectively.

[0017] By adopting the above technical solution, the fixed slide rod can provide a guiding up-and-down action for the second grinding wheel, and the two ends of the second limiting spring are fixedly connected to the first grinding wheel and the second grinding wheel. The reset force of the second limiting spring can keep the first grinding wheel and the second grinding wheel at a certain distance.

[0018] A further feature of this invention is that a fixing plate is fixed to the top of the mounting bracket by bolts, a mounting seat is provided on one side of the top of the fixing plate, and multiple limiting holes are symmetrically opened on both sides of the mounting seat.

The two ends of the first limiting spring are respectively fixedly connected to the bent component and the positioning pin.

[0023] By adopting the above technical solution, the positioning pin and the bent part are fixed at both ends of the first limiting spring, which prevents the positioning pin from separating from the bent part while giving the positioning pin a certain degree of mobility.

[0024] The beneficial effects of this utility model are as follows: the rotation of the second motor drives the lead screw to rotate, and the rotation of the lead screw drives the second grinding wheel to move upward through the fixed slide rod. While the second grinding wheel moves upward through the fixed slide rod, it stretches the second limit spring. By adjusting the distance between the first grinding wheel and the second grinding wheel, it is convenient to perform bending operations on bending tubes of various sizes. When it is necessary to replace or disassemble, one end of the positioning pin on both sides of the bent part is pulled out of the limit hole. The bent part is then moved upward and separated from the mounting seat through the T-shaped slide groove and T-shaped slider, which facilitates the quick installation and disassembly of the bent part and improves bending efficiency.

[0031] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Reference Figure 1-4 A pipe positioning device for a multi-axis pipe bending machine includes a pipe bending machine body 1, with support blocks 2 at each of the four bottom corners of the pipe bending machine body 1, a movable plate 3 at the top of the pipe bending machine body 1, a trolley chuck 4 at the top of the movable plate 3, and a movable seat 5 at the front end of the pipe bending machine body 1.

[0033] Reference Figure 1-3 Two slide rails 6 are symmetrically arranged on one side of the top of the movable seat 5, and a slide block 7 is arranged on the top of the two slide rails 6.

[0034] The bottom of the slide block 7 has a groove of corresponding size corresponding to the position of the two slide rails 6;

[0035] The top of the slide block 7 is fixed with a fixing block 8 by bolts, and a clamping limit plate 9 is provided on the front side of the fixing block 8;

[0036] A first motor 10 is installed inside one side of the movable seat 5, and a mounting bracket 11 is installed on one side of the movable seat 5. The upper and lower ends of one end of the mounting bracket 11 are movably connected to the movable seat 5.

[0037] The top of the first motor 10 passes through the mounting bracket 11 and is movably connected to the first grinding wheel 20 via a bearing. The top of the first grinding wheel 20 is provided with the second grinding wheel 21. The top of the second grinding wheel 21 is fixed with the second motor 22 by bolts. The bottom of the second motor 22 passes through the second grinding wheel 21 and is movably connected to the lead screw 23 via a bearing. The bottom of the lead screw 23 is threadedly connected to the inside of the first grinding wheel 20.

[0038] In this invention, one end of the pipe bending machine body 1 is positioned appropriately. Support blocks 2 at the four corners of the bottom of the pipe bending machine body 1 provide support for the pipe bending machine body 1. The pipe to be bent is fixed by the trolley claw 4. The position of the trolley claw 4 and the bent pipe can be adjusted by the movable plate 3. The slide 7 moves to one side via the slide rail 6. The slide 7 is guided to one side by the slide rail 6, which drives the fixing block 8 to move to one side. The fixing block 8 moves to one side, which drives the inverted clamping limit plate 9 to limit one side of the pipe to be bent. The second motor 22 is turned on. The rotation of the second motor 22 drives the lead screw 23 to rotate. The rotation of the lead screw 23 drives the second wheel mill 21 to move upward via the fixed slide rod 24. While the second wheel mill 21 moves upward via the fixed slide rod 24, the second limit spring 25 is stretched. By adjusting the distance between the first wheel mill 20 and the second wheel mill 21, it is convenient to perform bending operations on pipes of various sizes.

[0039] Reference Figure 2-4 Two fixed sliding rods 24 are set on both sides of the first grinding wheel 20. The top of the fixed sliding rod 24 is slidably connected to the second grinding wheel 21. A second limiting spring 25 is sleeved on the outside of the fixed sliding rod 24. The two ends of the second limiting spring 25 are fixedly connected to the first grinding wheel 20 and the second grinding wheel 21 respectively.

[0040] The top of the mounting bracket 11 is fixed with a fixing plate 12 by bolts. A mounting base 13 is provided on one side of the top of the fixing plate 12. Multiple limiting holes 15 are symmetrically opened on both sides of the mounting base 13.

[0041] The front end of the mounting base 13 is provided with a bending part 16. Two T-shaped sliders 17 are symmetrically arranged on the side of the bending part 16 near the mounting base 13. The mounting base 13 is provided with T-shaped grooves 14 of corresponding size at the positions of the two T-shaped sliders 17. The T-shaped sliders 17 are slidably connected to the T-shaped grooves 14.

[0042] Two positioning pins 18 are provided on both sides of the bent part 16 at the positions corresponding to the limiting holes 15. A first limiting spring 19 is sleeved on the outer side of one end of the positioning pin 18. The two ends of the first limiting spring 19 are fixedly connected to the bent part 16 and the positioning pin 18 respectively.

[0043] In this invention, the second motor 22 drives the lead screw 23 to rotate in the opposite direction. When the second limit spring 25 returns to its original position, the second grinding wheel 21 moves downwards to contact the bending tube, providing a certain clamping and fixing effect to the bending tube, preventing it from moving during the bending operation and affecting the bending effect. The positioning pins 18 on both sides of the bending piece 16 are pulled outwards. Simultaneously, the positioning pins 18 move, stretching the first limit spring 19. The T-shaped slider 17 on one side of the bending piece 16 is aligned with the T-shaped groove 14 on the front side of the mounting base 13 and inserted. The T-shaped slider 17 and... The T-shaped slide 14 guides the bending part 16 downwards, adjusting its height. The positioning pin 18 is then released, and the force of the first limit spring 19 pushing one end of the positioning pin 18 into the limit holes 15 on both sides of the mounting base 13 completes the fixing of the bending part 16. When replacement or disassembly is required, one end of the positioning pin 18 on both sides of the bending part 16 is pulled out of the limit holes 15. The bending part 16 is then moved upwards and separated from the mounting base 13 by the T-shaped slide 14 and T-shaped slider 17, facilitating the quick installation and disassembly of the bending part 16 and improving bending efficiency.
