Description
Technical Field
[0001] This utility model relates to the field of positioning and cutting equipment for seamless steel pipe processing, and in particular to a positioning and cutting device for seamless steel pipe processing. Background Technology
[0002] A positioning and cutting device is a piece of equipment used for precise material cutting. It mainly consists of two parts: a positioning system and a cutting system. The positioning system uses sensors and a control system to accurately identify and position the cutting location, ensuring cutting accuracy. The cutting system is responsible for the actual cutting of the material. Common cutting methods include laser cutting, plasma cutting, and waterjet cutting.
[0003] During the processing of seamless steel pipes, laser positioning and cutting devices are typically used for segmentation. These devices possess high-precision positioning capabilities, using a laser beam emitted from a laser emitter to quickly and accurately determine the cutting position of the seamless steel pipe. However, during the cutting operation, one end of the seamless steel pipe is usually firmly fixed in place by a chuck to ensure stability during the cutting process. Subsequently, the laser emitter performs the cutting operation. However, during the cutting process, the other end of the seamless steel pipe is not supported and is completely suspended in the air. Due to the continuous effect of gravity, this suspended state causes the steel pipe to deform to varying degrees at the cut position. This deformation not only directly affects the cutting accuracy but also negatively impacts the quality of the cut steel pipe, reducing its overall performance and aesthetics.
[0004] Therefore, in view of the problems existing in the prior art, this utility model provides a positioning and cutting device for seamless steel pipe processing, which aims to solve the deformation problem caused by the other end being suspended during the cutting of seamless steel pipe, thereby improving the cutting accuracy and cutting quality.

The support component includes a mounting plate, a support plate located on top of the mounting plate, a fixing seat fixed to the top of the support plate, a ball embedded in the inner cavity of the fixing seat, a spring located between the mounting plate and the support plate, and a bolt passing through the support plate and the spring and threadedly connected to the mounting plate. The lifting component includes a support frame fixedly connected to the top of the cutting table, a cylinder fixed to one side of the support frame by a fixing pin, and a roller rotatably connected to the output end of the cylinder by a movable pin.
[0007] Preferably, the support position of the fixed support component is determined according to the cutting size of the seamless steel pipe. The support component is slid to the desired position by moving the component. The mounting plate, support plate, and fixing seat can provide support for the seamless steel pipe. By loosening or tightening the bolts, the spring can be compressed or released, thereby adjusting the support height of the fixing seat. The ball bearings can provide auxiliary rolling when the seamless steel pipe rotates. After the seamless steel pipe is fixed by the fixing component, one end of it is located in the inner cavity of the fixing seat, which allows the support component to support the seamless steel pipe. The output end of the cylinder extends and pushes the roller to contact the bottom of the seamless steel pipe, thereby assisting the support component in supporting the seamless steel pipe. Through the coordinated cooperation of the support component and the lifting component, auxiliary support can be provided during the cutting of the seamless steel pipe to prevent deformation of the cut and affect the cutting quality.
[0008] Preferably, the moving assembly includes a slide fixed to the top of the cutting table, slide rods fixed to both sides of the top of the slide, and a slide block that slides on the surface of the slide rods.
[0009] Preferably, the locking assembly is disposed on one side of the slide block. The locking assembly includes a positioning plate fixedly connected to the slide block, a threaded hole formed on the surface of the positioning plate, a knob located on the surface of the positioning plate, an arc-shaped plate located on one side of the inner cavity of the slide block, and a threaded rod threadedly connected to the threaded hole. One end of the threaded rod is rotatably connected to the arc-shaped plate through a bearing, and the other end of the threaded rod is fixedly connected to the knob.
[0010] Preferably, the cutting assembly includes a support base fixed to the top of the cutting table, a support arm rotatably connected to the support base via a bearing, a laser emitter fixed to one end of the support arm, and a hydraulic cylinder movably connected to the support arm via a rotating shaft, wherein the tail end of the hydraulic cylinder is movably connected to the cutting table via a bearing.
[0011] Preferably, the fixing assembly includes a fixing plate fixed to the back of the cutting table, a pneumatic hollow chuck located on the front of the fixing plate, a drive shaft fixedly connected to the pneumatic hollow chuck, a drive motor and a reducer fixed to the back of the fixing plate, and a first synchronous pulley and a second synchronous pulley rotatably connected to the front of the fixing plate via bearings, wherein the first synchronous pulley and the second synchronous pulley are connected by a synchronous belt drive.

The top of the mounting plate is provided with a threaded hole that matches the bolt, and the two ends of the spring are fixedly connected to the mounting plate and the support plate, respectively.
[0015] The beneficial effects of this utility model are as follows: By setting up a lifting mechanism, the support component and the lifting component can work together to provide auxiliary support for the seamless steel pipe during the cutting process. In the support component, the lifting structure composed of the mounting plate, support plate and fixed seat can be slid to the required position by the moving component according to the cutting size of the seamless steel pipe. The support height of the fixed seat can be adjusted by loosening or tightening the bolts to compress or release the spring deformation to adapt to seamless steel pipes of different specifications. The ball bearings embedded in the inner cavity of the fixed seat can provide auxiliary rolling when the seamless steel pipe rotates, reduce friction and make the cutting process smoother. At the same time, the cylinder output end in the lifting component extends to push the roller to contact the bottom of the seamless steel pipe, further assisting the support component in supporting the seamless steel pipe, effectively preventing deformation of the cut due to the other end of the seamless steel pipe being suspended during cutting, thus improving cutting accuracy and cutting quality.

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] Example 1 Please see Figures 1-7This utility model provides an embodiment: a positioning and cutting device for seamless steel pipe processing, including a cutting table 100, a cutting component 200 installed on the top of the cutting table 100 for cutting, a fixing component 300 for fixing the seamless steel pipe, a lifting mechanism 500 for supporting the seamless steel pipe during cutting, a positioning component 600 for positioning the cutting, and a moving component 400 for adjusting the position of the lifting mechanism 500 and the positioning component 600. The lifting mechanism 500 includes a support component 510 and a lifting component 520 for support, and a locking component 530 for fixing the adjusted position. Two sets of moving components 400 are provided, and the support component 510 and the positioning component 600 are respectively located above the two moving components 400. The support component 510 includes a mounting plate 511 and a support plate 520 located on top of the mounting plate 511. 12. A fixed base 513 fixed to the top of the support plate 512, a ball bearing 514 embedded in the inner cavity of the fixed base 513, a spring 515 located between the mounting plate 511 and the support plate 512, and a bolt 516 passing through the support plate 512 and the spring 515 and threadedly connected to the mounting plate 511. The lifting assembly 520 includes a support frame 521 fixedly connected to the top of the cutting table 100, a cylinder 522 fixed to one side of the support frame 521 by a fixed pin, and a roller 523 rotatably connected to the output end of the cylinder 522 by a movable pin. The mounting plate 511 is fixed to the top of another set of slides 430. Ball bearings 514 are embedded on both sides of the inner cavity of the fixed base 513. The top of the mounting plate 511 is provided with a threaded hole that matches the bolt 516. The two ends of the spring 515 are fixedly connected to the mounting plate 511 and the support plate 512 respectively.
[0020] During operation, the lifting mechanism 500 includes a support assembly 510 and a lifting assembly 520. The ball bearings 514 and springs 515 of the support assembly 510 provide cushioning and elastic support to reduce the downward deformation caused by gravity. At the same time, the bolts 516 can adjust the support height to adapt to different steel pipe diameters. The cylinders 522 and rollers 523 of the lifting assembly 520 realize dynamic lifting to ensure that the steel pipe remains horizontal and stable during the cutting process and avoids deformation caused by stress concentration at the cut. The seamless steel pipe to be cut is fixed on the fixing component 300. At this time, according to the specifications of the seamless steel pipe and the cutting requirements, the position of the lifting mechanism 500 and the positioning component 600 is adjusted by the moving component 400. After the moving component 400 moves the support component 510 and the positioning component 600 to the appropriate position, the support plate 512 in the support component 510 can adaptively adjust to a certain extent according to the weight of the seamless steel pipe under the action of the spring 515. Meanwhile, the ball bearings 514 in the inner cavity of the fixing seat 513 can reduce the friction between the seamless steel pipe and the fixing seat. The friction between components 513 makes the seamless steel pipe placement smoother. At the same time, the cylinder 522 in the lifting component 520 is activated, pushing the roller 523 upward until the roller 523 contacts the bottom of the seamless steel pipe, providing stable support for the seamless steel pipe and preventing it from sagging and deforming due to gravity during the cutting process. The positioning component 600 precisely positions the cutting position of the seamless steel pipe to ensure the accuracy of the cutting. When all components are adjusted in place and the seamless steel pipe is fixed and stably supported, the cutting component 200 starts to work and performs the cutting operation on the seamless steel pipe.
[0021] Example 2 Please see Figure 1 , Figure 3 and Figure 7 The difference from Embodiment 1 is that the cutting assembly 200 includes a support base 210 fixed to the top of the cutting table 100, a support arm 220 rotatably connected to the support base 210 via a bearing, a laser emitter 230 fixed to one end of the support arm 220, and a hydraulic cylinder 240 movably connected to the support arm 220 via a rotating shaft, with the tail end of the hydraulic cylinder 240 movably connected to the cutting table 100 via a bearing. The fixing assembly 300 includes a fixing plate 310 fixed to the back of the cutting table 100, a pneumatic hollow chuck 320 located on the front of the fixing plate 310, and a pneumatic... The hollow chuck 320 is fixedly connected to the drive shaft 330, the drive motor 340 and the reducer 350 fixed to the back of the fixed plate 310, and the first synchronous pulley 360 and the second synchronous pulley 370 are rotatably connected to the front of the fixed plate 310 through bearings. The first synchronous pulley 360 and the second synchronous pulley 370 are connected by a synchronous belt. The output shaft of the reducer 350 is connected to the first synchronous pulley 360, the output shaft of the drive motor 340 is connected to the input shaft of the reducer 350, and the other end of the drive shaft 330 is fixedly connected to the second synchronous pulley 370.
[0022] During operation, a seamless steel pipe feeding device can be installed on the back of the cutting table 100 to drive the seamless steel pipe cutting operation. The drive shaft 330 is made of hollow tube to facilitate the seamless steel pipe to be inserted into the pneumatic hollow chuck 320 for clamping. A bracket can be installed at the bottom of the drive shaft 330 for support. The bracket and the drive shaft 330 are connected by bearings to facilitate the rotation of the drive shaft 330. After the seamless steel pipe is adjusted to the required cutting position, it is clamped and fixed by the pneumatic hollow chuck 320. The support component 510 and the lifting component 520 can lift and support the other end of the seamless steel pipe. After the seamless steel pipe is fixed, it is laser-driven by the laser emitter 230. In laser cutting, the output end of the hydraulic cylinder 240 extends and pushes one end of the support arm 220 upward, causing it to rotate around the support base 210 and the end of the laser emitter 230 downward, thereby adjusting the cutting height of the laser emitter 230. At the same time, the drive motor 340 provides power, which drives the first synchronous pulley 360 to rotate through the reducer 350. The first synchronous pulley 360 drives the second synchronous pulley 370 to rotate through the synchronous belt. When the second synchronous pulley 370 rotates, it drives the pneumatic hollow chuck 320 to rotate through the transmission shaft 330, which in turn drives the seamless steel pipe to rotate, thus facilitating the laser emitter 230 to perform cutting operations.
[0023] Example 3 Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 The difference from Embodiment 1 is that the moving assembly 400 includes a slide 410 fixed to the top of the cutting table 100, slide rods 420 fixed to both sides of the top of the slide 410, and a slide base 430 sliding on the surface of the slide rods 420. A locking assembly 530 is disposed on one side of the slide base 430. The locking assembly 530 includes a positioning plate 531 fixedly connected to the slide base 430, a threaded hole 532 formed on the surface of the positioning plate 531, and a knob 533 located on the surface of the positioning plate 531. The positioning assembly 600 includes an arc-shaped plate 534 located on one side of the inner cavity of the slide 430, and a threaded rod 535 threadedly connected to the threaded hole 532. One end of the threaded rod 535 is rotatably connected to the arc-shaped plate 534 through a bearing, and the other end of the threaded rod 535 is fixedly connected to the knob 533. The positioning assembly 600 includes a fixed platform 610 fixed to the top of a set of slides 430, a servo motor 620 fixed to the top of the fixed platform 610, and a baffle 630 that is drivenly connected to the output shaft of the servo motor 620.
[0024] During operation, a rangefinder can be added to the positioning component 600 to measure the cutting dimensions of the seamless steel pipe. A measuring ruler can also be fixed on the surface of the moving component 400, which is used to move the positioning component 600, to determine the dimensions of the seamless steel pipe. The moving fixed platform 610 slides on the surface of the slide rod 420 via the slide block 430. After sliding to the desired cutting position, it is fixed by the locking component 530. Rotating the knob 533 causes the threaded rod 535 to rotate along the inner cavity of the threaded hole 532, pushing the arc plate 534 into close contact with the slide rod 420, thereby limiting the slide block 430 and fixing the adjusted position. The output shaft of the servo motor 620 rotates, causing the baffle 630 to rotate to one side. The baffle 630 contacts one end of the seamless steel pipe. The baffle 630 works in conjunction with the measuring ruler or measuring instrument to accurately position the cutting position of the seamless steel pipe, preventing the cut from being too long or too short.
