Description

Technical Field

[0001] This utility model relates to the field of metal cutting technology, and in particular to a cutting positioning device. Background Technology

[0002] Metal pipes are widely used in many industrial sectors today, such as construction, machinery manufacturing, and pipeline engineering. Cutting and processing metal pipes is a crucial step in ensuring they meet the practical needs of various projects. However, with the continuous expansion of modern industrial production and increasingly stringent quality requirements, traditional metal pipe cutting and positioning methods are gradually revealing numerous insurmountable limitations.

[0003] Traditionally, metal pipe cutting relies heavily on manual operation for processes such as loading, positioning, and clamping the pipes. For example, workers manually move the pipes to the cutting area, relying on experience and simple measuring tools to estimate and determine the cutting position. They then use conventional clamps (such as manual calipers) to clamp and secure the pipes to prevent displacement during the cutting process. However, this manual-driven approach has significant drawbacks.

[0004] Firstly, from an efficiency perspective, manual operation is cumbersome and time-consuming. The loading, positioning, and clamping of each pipe requires workers to invest a significant amount of time and effort, making the entire cutting and processing process extremely inefficient and far from meeting the high-efficiency requirements of large-scale industrial production. This problem of slow production progress caused by manual operation becomes even more prominent when facing batch pipe cutting tasks, severely restricting the improvement of production efficiency.

[0005] Secondly, regarding positioning accuracy, human judgment and operation are prone to introducing significant errors. Due to varying levels of skill and experience among workers, even with the aid of measuring tools, achieving high-precision positioning in determining the pipe cutting location and ensuring its placement angle remains difficult. This leads to inconsistent dimensional and shape accuracy of the cut pipes, frequently resulting in quality issues such as dimensional deviations and uneven cut surfaces. This not only wastes raw materials but also causes numerous inconveniences in subsequent pipe assembly and use, even impacting the overall project quality and schedule.

[0006] Therefore, it is necessary to provide a new cutting and positioning device to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a cutting and positioning device.

[0008] The present invention provides a cutting and positioning device comprising: a base plate, two support plates fixedly connected to the upper end of the base plate, a rotating rod rotatably connected to the adjacent sides of the two support plates, a plurality of discs fixedly connected to the rotating rod, an arc-shaped groove provided on the outer side of each of the plurality of discs, the plurality of arc-shaped grooves being arranged in a circular array, a drive motor mounted on the support plate located on the rear side, the output shaft end of the drive motor being fixedly connected to the rotating rod, two first pneumatic rods fixedly connected to the adjacent sides of the two support plates, and a clamping block fixedly connected to the telescopic ends of each of the plurality of first pneumatic rods.

[0009] Preferably, an L-shaped block is fixedly connected to the rear side of the base plate, and two second pneumatic rods are provided on the left side of the L-shaped block. The telescopic ends of the two second pneumatic rods are fixedly connected to a moving block. Two feeding blocks are fixedly connected to the left side of the moving block, and multiple placement slots are provided on the upper end of each of the two feeding blocks.

[0010] Preferably, two slide rails are fixedly connected to the left side of the L-shaped block, and a slider is slidably connected to both slide rails. Two third pneumatic rods are fixedly connected to the upper end of the L-shaped block, and the telescopic ends of the two third pneumatic rods are fixedly connected to the lower end of the slider. The two second pneumatic rods are fixedly connected to the slider.

[0011] Preferably, a baffle is fixedly connected to the right side of the moving block, the baffle is located above the two second pneumatic rods, and the upper surface of the baffle is flush with the upper surface of the two feeding blocks.

[0012] Preferably, the two support plates are fixedly connected to a feeding channel on their adjacent sides, a baffle is fixedly connected to the upper end of the feeding channel, and an inclined plate is fixedly connected to the right side of the feeding channel, with a rolling groove provided on the inclined plate.

[0013] Preferably, each of the clamping blocks is provided with a rubber anti-slip pad on the side away from the first pneumatic rod, and each rubber anti-slip pad has multiple anti-slip patterns evenly distributed on it. The disc is made of high-strength alloy steel and the outer surface of the disc is chrome-plated.

[0014] Preferably, the inner walls on both sides of the feeding channel are provided with multiple rollers, the outer surfaces of the multiple rollers are covered with wear-resistant rubber, and the multiple rollers are arranged at equal intervals.

[0015] Compared with related technologies, the cutting and positioning device provided by this utility model has the following advantages:

[0016] 1. This utility model provides a cutting and positioning device that achieves automatic feeding and neat arrangement of metal pipes through the coordinated operation of structures such as inclined plates, feeding channels, and feeding blocks. During initial feeding, the inclined plates and the guiding effect of the feeding channels allow the metal pipes placed in the rolling groove to automatically fall into the feeding channels and achieve a vertical and neat arrangement at the feeding block directly below them. This effectively avoids the problems of messy pipe placement and inaccurate positioning in traditional manual feeding methods, greatly improving feeding efficiency, saving labor costs, and laying a good foundation for subsequent precise cutting.

[0017] 2. This utility model provides a cutting and positioning device that achieves precise positioning and stable clamping by cooperating with multiple pneumatic rods and corresponding structures. For example, the second and third pneumatic rods, along with components such as the feeding block and slider, work together to accurately feed the pipe into the arc-shaped groove of the disc. The clamping block driven by the first pneumatic rod, relying on its rubber anti-slip pad, can not only reliably align the pipe but also firmly clamp it during the cutting process, preventing the pipe from shifting due to external cutting forces. This ensures the accuracy of the cutting position and the flatness of the cutting surface, significantly improving the cutting quality and reducing cutting errors and material waste caused by pipe displacement.

[0018] 3. This utility model provides a cutting and positioning device that achieves a smooth and efficient feeding and unloading process through a reasonable structural design throughout the cutting process. After each cut is completed by the drive motor rotating the pipe, the second and third pneumatic rods sequentially contract and extend, thus placing the new metal pipe in the appropriate position in an orderly manner. This facilitates continuous cutting operations, ensures the continuity of the cutting process, reduces equipment downtime, and further improves production efficiency. It also avoids situations such as jamming or accumulation of pipes during unloading that could affect the normal operation of the equipment, reducing equipment maintenance costs and making the entire cutting process more stable, reliable, and efficient.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 3 A cutting and positioning device includes: a base plate 1, two support plates 2 fixedly connected to the upper end of the base plate 1, a rotating rod 3 rotatably connected to the adjacent sides of the two support plates 2, a plurality of discs 4 fixedly connected to the rotating rod 3, an arc groove 5 provided on the outer side of each of the plurality of discs 4, the plurality of arc grooves 5 being arranged in a ring array, a drive motor 14 installed on the support plate 2 located on the rear side, the output shaft end of the drive motor 14 being fixedly connected to the rotating rod 3, two first pneumatic rods 6 fixedly connected to the adjacent sides of the two support plates 2, a pressing block 7 fixedly connected to the telescopic end of each of the plurality of first pneumatic rods 6, a rubber anti-slip pad provided on the side of each pressing block 7 away from the first pneumatic rod 6, a plurality of anti-slip patterns evenly distributed on each rubber anti-slip pad, the discs 4 being made of high-strength alloy steel, and the outer surface of the discs 4 being chrome-plated.

[0025] It should be noted that disc 4 is made of high-strength alloy steel, a material chosen with careful consideration. High-strength alloy steel possesses excellent mechanical properties; its high strength and high toughness ensure that disc 4 maintains structural integrity even under the weight of the metal pipe and various complex external forces generated during the cutting process, without deformation or damage. This guarantees the stability and reliability of the entire cutting and positioning device, providing a solid foundation for precise cutting.

[0026] The base plate 1 has an L-shaped block 11 fixedly connected to its rear side. The left side of the L-shaped block 11 has two second pneumatic rods 15. The telescopic ends of the two second pneumatic rods 15 are fixedly connected to a moving block 17. The left side of the moving block 17 has two feeding blocks 18 fixedly connected to its left side. The upper end of each of the two feeding blocks 18 has multiple placement slots 19. The left side of the L-shaped block 11 has two slide rails 12 fixedly connected to its left side. The two slide rails 12 are slidably connected to a slider 13. The upper end of the L-shaped block 11 has two third pneumatic rods 16 fixedly connected to its right side. The telescopic ends of the two third pneumatic rods 16 are fixedly connected to the lower end of the slider 13. The two second pneumatic rods 15 are fixedly connected to the slider 13. The right side of the moving block 17 has a baffle 9 fixedly connected to its right side. The baffle 9 is located above the two second pneumatic rods 15. The upper surface of the baffle 9 is flush with the upper surface of the two feeding blocks 18.

[0027] It should be noted that the multiple placement slots 19 on the two feeding blocks 18 connected to the left side of the moving block 17 are specifically designed to accommodate metal pipes of different sizes and specifications. The shape and size of the placement slots 19 can be reasonably adjusted according to the common pipe sizes in actual applications, allowing the pipes to be placed stably within them, preventing shaking or offset during feeding and ensuring feeding accuracy. The baffle 9 fixedly connected to the right side of the moving block 17 is positioned above the two second pneumatic rods 15, with its upper surface flush with the upper surface of the two feeding blocks 18. This design plays a crucial blocking role. During feeding, as the pipes are conveyed along with the moving feeding blocks 18, the baffle 9 effectively prevents other pipes in the discharge channel 8 from continuing to fall, avoiding pipe accumulation and ensuring the orderliness and uniformity of each feeding operation. This further improves the accuracy and stability of the entire device's feeding process, contributing to a continuous and efficient cutting process.

[0028] Among them, the two support plates 2 are fixedly connected to the adjacent sides of the feeding channel 8, the upper end of the feeding channel 8 is fixedly connected to the baffle 9, the right side of the feeding channel 8 is fixedly connected to the inclined plate 10, the inclined plate 10 is provided with a rolling groove, the inner walls of the left and right sides of the feeding channel 8 are provided with multiple rollers, the outer surface of the multiple rollers is covered with wear-resistant rubber, and the multiple rollers are arranged at equal intervals.

[0029] It should be noted that the rolling grooves on the inclined plate 10 and the multiple rollers arranged at equal intervals on the inner walls of the left and right sides of the feeding channel 8, with their outer surfaces covered with wear-resistant rubber, work together to enable the pipe to move more smoothly during feeding. The rolling grooves provide initial guidance and restraint for the pipe, allowing it to roll in a predetermined direction; the rollers reduce the friction between the pipe and the inner wall of the feeding channel 8, allowing the pipe to fall easily along the feeding channel 8 under the action of gravity.

[0030] The working principle of the cutting and positioning device provided by this utility model is as follows: When cutting metal pipes, four metal pipes of equal length are placed in the rolling groove. Due to the inclined plate 10, the metal pipes will fall into the feeding channel 8. Since the feeding block 18 is located directly below the feeding channel 8, the metal pipes are arranged vertically and neatly in the feeding channel 8.

[0031] The two second pneumatic rods 15 are stretched to make the tubes fall neatly into the multiple placement slots 19. As the second pneumatic rods 15 continue to stretch, the baffle 9 will block the metal tubes in the feeding channel 8, preventing the metal tubes from falling. When the feeding block 18 feeds the tubes into the arc-shaped slot 5 on the right, the third pneumatic rod 16 is retracted to make the feeding block 18 move down, thereby placing the metal tubes in the two arc-shaped slots 5. Since the third pneumatic rod 16 moves down a small distance to place the metal tubes in the arc-shaped slots 5, the baffle 9 will not cause the metal tubes in the feeding channel 8 to fall out of the feeding channel 8.

[0032] After the metal pipe is placed, first control the two first pneumatic rods 6 on the right side to stretch, so that the two clamping blocks 7 move relative to each other, and then the pipe in the arc groove 5 is aligned. The staff controls the drive motor 14 to run, so that the metal pipe rotates to the right side, and then the cutting machine can be used to cut the metal pipe.

[0033] After each drive motor 14 runs, the second pneumatic rod 15 is first controlled to retract a certain distance, then the third pneumatic rod 16 is controlled to extend, then the second pneumatic rod 15 is controlled to retract, and then the third pneumatic rod 16 is controlled to retract, so that the new metal pipe can be placed in the arc-shaped groove 5 located on the right side at this time, thus facilitating the loading and unloading of the metal pipe.

[0034] When cutting metal pipes, it is necessary to control the stretching of the two first pneumatic rods 6 on the left side, so that the two clamping blocks 7 on the left side can move relative to each other, thereby clamping the metal pipes and preventing the metal pipes from shifting during cutting.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
