Description

Technical Field

[0002] A pipe cutter is a machine specifically designed for cutting pipes. It is commonly used in industries such as construction, manufacturing, and aerospace. It can cut pipes of various materials, such as copper, steel, iron, and aluminum. Currently, existing pipe cutters have poor pipe fixing effects, which makes the pipes prone to shifting during cutting, thus affecting the cutting quality.

[0003] As disclosed in the prior art, Chinese utility model publication CN220462407U discloses a pipe cutting machine. This utility model includes a cutting table, a lower rubber clamping roller, and a clamping mechanism. The clamping mechanism includes a frame, the inner top surface of which is fixedly connected to the base of a first hydraulic cylinder. The output shaft end of the first hydraulic cylinder is fixedly connected to the top surface of an upper clamping frame cover. The inner surface of the upper clamping frame cover is rotatably connected to the wall of the upper rubber clamping roller. In the above structure, the pipe is clamped only by the upper and lower rubber clamping rollers. Since the rubber roller is circular, the contact area with the pipe is limited. When clamping the pipe, slippage or instability is likely to occur, which means that the pipe is prone to displacement during the cutting process. Therefore, we need to propose a pipe cutting machine with anti-displacement function. Utility Model Content

By setting up a base plate, a first support frame, a cutting machine, a fixing plate and an anti-deviation mechanism, the pipe is surrounded by arc grooves on two sets of lower clamping seats and upper clamping seats, which increases the contact area with the pipe.

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

[0016] Please see Figure 1-4 This utility model provides a technical solution: A pipe cutting machine with anti-deviation function includes: a base plate 1, and a first support frame 2 is fixedly installed on the top of the base plate 1, and a cutting machine 3 is arranged inside the first support frame 2; a fixed plate 4, installed on the top of the base plate 1; an anti-deviation mechanism 5 for preventing the pipe from deviating during cutting, and the anti-deviation mechanism 5 is arranged on the top of the fixed plate 4; the anti-deviation mechanism 5 includes two sets of lower clamping seats 51, two sets of second support frames 52, two sets of connecting plates 53, two sets of upper clamping seats 54, multiple sets of arc grooves 55, and two sets of driving members 56; the two sets of lower clamping seats 51 and the two sets of second support frames 52 are symmetrically fixedly installed on the top of the fixed plate 4, the two sets of driving members 56 are respectively arranged inside the two sets of support frames, the two sets of connecting plates 53 are respectively installed at the bottom of the two sets of driving members 56, the two sets of upper clamping seats 54 are respectively fixedly installed at the bottom of the two sets of connecting plates 53, and arc grooves 55 are respectively opened on the opposite side of the two sets of lower clamping seats 51 and the two sets of upper clamping seats 54.

[0017] Through the coordinated arrangement of the base plate 1, the first support frame 2, the cutting machine 3, the fixing plate 4 and the anti-deviation mechanism 5, the lower clamping seat 51 and the upper clamping seat 54 are fixedly installed by bolts, so that the two can be flexibly replaced according to the specific size of the pipe, which can adapt to more different specifications of pipes and broaden the application range of the pipe cutting machine. Among them, the arc groove 55 is equipped with rubber anti-slip pads, which can increase the friction coefficient with the surface of the pipe through the high friction characteristics of the rubber material, reduce the relative sliding of the pipe during the clamping process, and further enhance the anti-deviation effect. At the same time, the rubber material has a certain elasticity, which can buffer the impact force during clamping and avoid surface scratches caused by direct contact between the hard clamping seat and the pipe. While ensuring the stability of clamping, it protects the appearance quality of the pipe. Meanwhile, the enclosed clamping formed by the arc-shaped grooves 55 of the two sets of lower clamping seats 51 and upper clamping seats 54 increases the contact area. With the help of the drive component 56 to adjust the clamping force, it can effectively prevent the pipe from shifting during cutting. Moreover, the two sets of clamping structures are symmetrically distributed on both sides of the cutting machine 3, which further improves the stability of the pipe during cutting and ensures the cutting accuracy.

[0018] Specifically, the driving component 56 includes a motor 561, a threaded rod 562, a movable plate 563, and two sets of movable rods 564. The motor 561 is fixedly installed on the top of the second support frame 52, and the output end of the motor 561 is fixedly connected to the top end of the threaded rod 562 through a coupling. The threaded rod 562 is rotatably installed on the inner top of the second support frame 52. The movable plate 563 is threadedly connected to the outer side of the threaded rod 562. The top ends of the two sets of movable rods 564 are fixedly connected to the bottom of the movable plate 563, and the bottom ends of the two sets of movable rods 564 are fixedly connected to the top of the connecting plate 53.

[0019] With the configuration of motor 561, threaded rod 562, moving plate 563 and two sets of moving rods 564, motor 561 can be an MD-220 stepper motor as the driving force. When motor 561 drives threaded rod 562 to rotate, it drives moving plate 563 to move stably through thread transmission. Then, moving rod 564 pushes upper clamping seat 54 to rise and fall precisely, realizing precise control of the clamping force of the pipe, thereby improving the stability and reliability of the anti-deviation effect.

[0020] The second support frame 52 has a support plate 6 fixedly installed inside, and the bottom end of the threaded rod 562 is rotatably installed on the top of the support plate 6.

[0021] With the support plate 6, the support plate 6 inside the second support frame 52 provides bottom support for the threaded rod 562, which enhances the stability of the threaded rod 562 when it rotates, avoids shaking or bending caused by the threaded rod 562 being too long or under too much force, ensures the smoothness of the transmission process of the drive component 56, indirectly improves the lifting accuracy of the upper clamping seat 54, and further ensures the stability of the clamping.

[0022] Specifically, the support plate 6 has two sets of through holes 7 symmetrically opened inside, and two sets of moving rods 564 are respectively slidably arranged inside the two sets of through holes 7.

[0023] By setting through hole 7, through hole 7 on support plate 6 guides moving rod 564, restricts radial sway of moving rod 564, and causes moving rod 564 to drive upper clamping seat 54 to rise and fall in a straight line, ensuring that upper clamping seat 54 and lower clamping seat 51 arc groove 55 are precisely aligned, avoiding uneven force on pipe caused by upper clamping seat 54 offset, and enhancing anti-offset effect.

[0024] In a further preferred embodiment, sliders 8 are fixedly installed on both sides of the movable plate 563, and grooves 9 for sliding of sliders 8 are respectively opened on both sides inside the two sets of second support frames 52.

[0025] By setting up slider 8 and slide groove 9, the rotational freedom of moving plate 563 is restricted, so that moving plate 563 can only move stably along the axial direction of threaded rod 562, thus ensuring the accuracy and stability of the lifting action of upper clamping seat 54.

[0026] Specifically, a connecting frame 10 is fixedly installed on the outside of the cutting machine 3, and an electric push rod 11 is fixedly installed on the top of the first support frame 2. The telescopic end of the electric push rod 11 passes through the first support frame 2 and is fixedly connected to the top of the connecting frame 10.

[0027] With the connection frame 10 and the electric push rod 11, the electric push rod 11 can be a Limtech LBP22 ball screw electric push rod. The electric push rod 11 drives the cutting machine 3 to rise and fall, which improves the convenience and accuracy of the position adjustment of the cutting machine 3. The connection frame 10 stably transmits the power of the electric push rod 11 to the cutting machine 3, ensuring the stability of the position of the cutting machine 3 during the cutting process and avoiding the exacerbation of pipe deviation due to the shaking of the cutting machine 3. In conjunction with the anti-deviation mechanism 5, it further ensures the cutting quality.

[0028] Two sets of guide rods 12 are symmetrically fixedly installed on the top of the connecting frame 10, and both sets of guide rods 12 are slidably arranged on the inner top of the first support frame 2.

[0029] The two sets of guide rods 12 provide guidance and support for the lifting and lowering of the cutting machine 3, effectively preventing the cutting machine 3 from tilting or shaking during the lifting and lowering process, ensuring the straightness of the cutting trajectory, and further improving the overall cutting accuracy.

[0030] Working Principle: In practical application, the pipe to be cut is first placed in the arc-shaped grooves 55 of the two sets of lower clamping seats 51, aligning the cutting position of the pipe with the cutting machine 3. Then, the drive unit 56 in the anti-deviation mechanism 5 is activated, and the motor 561 rotates, driving the threaded rod 562 to rotate. Since the moving plate 563 is threadedly connected to the threaded rod 562, and the sliders 8 on both sides of the moving plate 563 slide within the grooves 9 of the second support frame 52, the rotation of the moving plate 563 is restricted, thus... The movable plate 563 moves downward along the axial direction of the threaded rod 562. When the movable plate 563 moves downward, it drives the two sets of movable rods 564 to move downward synchronously. After the movable rods 564 pass through the through hole 7 of the support plate 6, they push the connecting plate 53 and the upper clamping seat 54 at the bottom to move downward until the arc groove 55 of the upper clamping seat 54 is tightly attached to the surface of the pipe. The other set of upper clamping seats 54 operates in the same way. The arc groove 55 of the upper and lower clamping seats 51 forms a closed clamping on the pipe, thereby achieving anti-displacement fixation. Once the pipe is fixed, the electric push rod 11 on the first support frame 2 is activated. The telescopic end of the electric push rod 11 extends downward, pushing the connecting frame 10 and the cutting machine 3 at the bottom to move down. At the same time, the two sets of guide rods 12 at the top of the connecting frame 10 slide along the inner top of the first support frame 2 to ensure the stability of the cutting machine 3 during the downward movement. When the cutting machine 3 contacts the pipe, the pipe is cut.
