Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe cutting, and specifically provides a cutting distance positioning and assisting device for preventing steel pipe deviation. Background Art

[0002] Steel pipes are tubular products made of steel. They have characteristics such as pressure resistance, corrosion resistance, and high temperature resistance, and are widely used in many fields, including construction, engineering, petrochemical, automotive manufacturing, aerospace, etc. Steel pipes can be classified and manufactured according to different standards and requirements. Common types of steel pipes include seamless steel pipes, welded steel pipes, and galvanized steel pipes, etc. Seamless steel pipes are processed by cold drawing or hot rolling, with smooth inner and outer surfaces, and are suitable for high-pressure and high-temperature environments. Welded steel pipes are made by connecting steel plates or steel strips through a welding process, with lower production costs. Galvanized steel pipes are coated with a layer of zinc on the surface to prevent steel pipe corrosion. Steel pipes can adopt different materials and specifications according to their uses and specific requirements. Common steel pipe materials include carbon steel, stainless steel, alloy steel, etc. Steel pipes have a wide range of applications in various fields. For example, in construction, steel pipes are used for supporting structures, ventilation ducts, and drainage pipes. In the aerospace field, steel pipes are used for manufacturing the structures and hydraulic systems of aircraft;

[0003] Among them, there are the following problems in steel pipe cutting;

[0004] Existing fixing devices for cutting steel pipes are usually clamping devices, which are used to fix steel pipes to ensure a stable position during the cutting process. Due to the different shapes and materials of steel pipes, traditional clamping devices cannot achieve uniform clamping of steel pipes, resulting in deviation or deformation during the cutting process. Steel pipe deviation will cause the cutting line to be uneven and the cut surface to be uneven, thus affecting the cutting quality. An uneven cutting line will cause the cutting to deviate from the predetermined position, and an uneven cut surface will affect subsequent processing and connection work. Steel pipe deviation will cause incorrect contact between the cutting blade and the steel pipe, thereby increasing the risk of accidents such as caliper jamming, tool jamming, and flying cutting debris. In addition, sudden deviation of the steel pipe during cutting will cause harm to the operator. Once the steel pipe deviates, it is necessary to stop cutting, re-clamp, and adjust the cutting equipment, which will waste time and resources and affect work efficiency. Due to the decline in cutting quality, safety hazards, and time waste caused by steel pipe deviation, the progress of the project will be delayed, affecting the completion of the project schedule.

[0005] Therefore, a cutting distance positioning and assisting device for preventing steel pipe deviation is proposed. Summary of the Invention

[0010] Preferably, the adjusting passage groove is a groove symmetrically penetrated in the horizontal direction of the center of the adjusting rod and adapted to the adjusting teeth.

[0011] Preferably, the fixing groove is configured as a groove which is symmetrically opened in the vertical direction with respect to the center of the adjusting passage groove and is adapted to the adjusting tooth.

[0012] Preferably, the second connecting slider is slidably connected to the interior of the push-connecting block.

[0015] The cutting distance positioning method for preventing the steel pipe from deflecting comprises the following steps:

[0016] Step 1: Sleeve the steel pipe to be cut onto the surface of the rubber sleeve;

[0017] Step 2: Adjust the position of the work plate on the cutting table and refer to the scale display of the measuring ruler;

[0018] Step 3: When the steel pipe needs to be cut, move to the position indicated by the measuring ruler scale, use an external machine to perform the cutting operation.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The position of the steel pipe on the rubber sleeve is fixed, enabling the subsequent cutting process of the steel pipe by the staff. This reduces the influence of external factors on the cutting accuracy of the steel pipe, ensuring the accuracy and consistency of the cutting line. The clamping of the inner part of the steel pipe by the rubber sleeve effectively reduces the vibration and deformation of the steel pipe during the cutting process, avoiding excessive or insufficient cutting caused by unstable clamping during the cutting process, resulting in waste and loss during the cutting process. Further, it reduces the cutting cost, reduces the generation of waste, and avoids the problem that the traditional clamping device cannot achieve uniform clamping of the steel pipe, resulting in uneven cuts caused by the offset of the steel pipe, thereby affecting the cutting quality. It reduces the risk of accidents such as calipers, cutter jams, and flying cutting debris caused by incorrect contact between the cutting blade and the steel pipe due to the offset of the steel pipe, ensuring the cutting efficiency of the steel pipe and avoiding harm to the operator caused by the offset of the steel pipe during cutting.

[0023] 2. By rotating the fixed rod, the second sliding block is driven to slide into the fixed groove by restricting the sliding rod. At this time, the second limiting spring elastically extends, and the second sliding block abuts against the inside of the fixed groove. Then, the adjusting work plate is fixed at this time, avoiding the situation where the cutting position cannot be accurately determined during cutting due to unclear marking lines marked by the staff during cutting, reducing inaccurate manual marking, resulting in waste of steel pipes, increasing the consumption and cost of raw materials, and solving the problem of low production efficiency caused by the need for a long time for manual measurement and marking. The measuring ruler provides a more accurate measurement standard. Compared with the traditional manual measurement and marking methods, it improves the cutting accuracy and accuracy, ensuring greater stability during the steel pipe cutting process.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 to 8 , the embodiment provided by the present invention:

[0039] Embodiment 1:

[0040] A cutting distance positioning and assisting device for preventing the offset of steel pipes, including a cutting workbench 1, and a clamping adjustment assembly for internally expanding and clamping steel pipes is arranged on the upper surface of the cutting workbench 1;

[0041] The clamping adjustment assembly includes a sliding support plate 21, which is fixedly connected to the upper surface of the cutting workbench 1. Fixed slots 22 are symmetrically formed on the outer side of the sliding support plate 21. The fixed slots 22 are grooves that are symmetrically formed in the vertical direction of the center of the adjustment passage groove 26 and are adapted to the adjustment teeth 29. First sliding slots 23 are symmetrically formed on the outer side of the sliding support plate 21. A first sliding block 24 is slidably connected inside the first sliding slot 23. The first sliding block 24 is fixedly connected to the bottom of the adjustment work plate 25. An adjustment work plate 25 is slidably connected to the upper surface of the sliding support plate 21. An adjustment passage groove 26 is formed through the surface of the adjustment work plate 25. Fixed slots 22 are symmetrically formed on the surface of the sliding support plate 21 in a linear array. An adjustment rod 28 is slidably connected inside the adjustment passage groove 26. One end of the adjustment rod 28 away from the adjustment work plate 25 is rotatably connected to a cross linkage block 210. Four push link rods 211 are rotatably connected to the cross linkage block 210. The number of the push link rods 211 is set to four, and the number of the push link rods 211 and the extension arc plates 213 is set to four. One end of each push link rod 211 away from the cross linkage block 210 is rotatably connected to a push link block 212. One end of the push link block 212 away from the first connection slider 218 is fixedly connected to the limit vertical plate 216. One end of the push link block 212 close to the first connection slider 218 is fixedly connected to the first connection slider 218. One side of each push link block 212 away from the push link rod 211 is fixedly connected to an extension arc plate 213. The number of the extension arc plates 213 is set to four. A rubber sleeve 214 is sleeved on the outer surface of the extension arc plate 213. A limit bottom plate 215 is fixedly connected to one side of the adjustment work plate 25 close to the cross linkage block 210. Limit vertical plates 216 are fixedly connected to the surface of the adjustment work plate 25 in a circular and uniform manner. The adjustment passage groove 26 is a groove that is symmetrically formed through the center of the adjustment rod 28 in the horizontal direction and is adapted to the adjustment teeth 29. A second sliding slot 217 is formed on one side of each limit vertical plate 216 close to the cross linkage block 210. A second connection slider 219 is fixedly connected to one side of each extension arc plate 213 close to the limit bottom plate 215. The second connection slider 219 and the inside of the push link block 212 are both slidably connected. A first connection slider 218 is slidably connected inside the push link block 212. A sliding connection rod 220 is fixedly connected to one side of each first connection slider 218 away from the limit bottom plate 215. A first limit spring 221 is sleeved on the surface of each sliding connection rod 220. Adjustment teeth 29 are uniformly fixedly connected to one side of the adjustment rod 28 away from the cross linkage block 210;

[0042] Among them: the first limit spring 221 serves to help the adjustable assembly reset. The sliding connection rod 220 serves to guide the first limit spring 221. The first sliding block 24 and the adjustment work plate 25 serve to help limit the adjustment work plate 25. Among them, the number of the push link rods 211 and the extension arc plates 213 is set to four.

[0043] More preferably: when the adjusting tooth 29 fits against the inner wall of the adjusting limit groove 27 , the elastic extension of the first limit spring 221 is restricted, and the deflection displacement of the second connecting slider 219 is restricted by the second sliding groove 217 .

[0044] A limiting component for limiting the movement of the clamping and adjusting component is symmetrically arranged at the bottom of the adjusting working plate 25, and the limiting component includes a third sliding groove 31, and the third sliding groove 31 is symmetrically opened at the top of the third sliding groove 31, and the inside of the third sliding groove 31 is slidably connected with a second sliding block 32, and the shape of the second sliding block 32 is adapted to the fixed groove 22, and the side of the second sliding block 32 away from the fixed groove 22 is fixedly connected with a limiting sliding rod 33, and the outer surface of the limiting sliding rod 33 is sleeved with a second limiting spring 34, and the end of the second limiting spring 34 away from the fixed shell 36 is fixedly connected to the second sliding block 32, and the end of the second limiting spring 34 close to the fixed shell 36 is fixedly connected to the adjusting working plate 25, and the end of the second limiting spring 34 away from the second sliding block 32 is fixedly connected with a rotating fixed rod 35, and the outer wall of the rotating fixed rod 35 is rotatably connected with the fixed shell 36, and the upper surface of the cutting workbench 1 is fixedly connected with a measuring ruler 4.

[0045] Better: When the adjusting working plate 25 drives the steel pipe to move to the required cutting position through the rubber sleeve 214, the staff rotates the fixed shell 36 on the outer wall of the rotating fixing rod 35. At this time, the second limit spring 34 elastically stretches. The second limit spring 34 drives the staff to bend the fixed shell 36. The fixed shell 36 rotates on the outer surface of the rotating fixing rod 35. The fixed shell 36 drives the limiting sliding rod 33 by rotating the fixing rod 35. The limiting sliding rod 33 drives the second sliding block 32 to slide inside the third sliding groove 31. At this time, the second limit spring 34 elastically stretches the second sliding block 32 to conflict with the inside of the fixed groove 22. At this time, the adjusting working plate 25 is fixed.

[0046] Embodiment 2:

[0047] The cutting distance positioning method for preventing the steel pipe from deflecting comprises the following steps:

[0048] Step 1: Sleeve the steel pipe to be cut onto the surface of the rubber sleeve 214;

[0049] Step 2: Adjust the position of the working plate 25 on the cutting table 1 and refer to the scale display of the measuring ruler 4;

[0050] Step 3: When the steel pipe needs to be cut, move to the position indicated by the 4 scales on the measuring ruler, use an external machine to perform the cutting operation.

[0051] The scale of the measuring ruler 4 in step 2 is in millimeters.

[0052] The external mechanical device in step three is set as a pipe cutting machine.

[0053] Working principle: In the initial state, the inner wall of the steel pipe is usually designed to be circular, which can ensure a tight connection with the rubber sleeve 214 and provide stable sealing performance. The staff sleeved the steel pipe on the outer surface of the rubber sleeve 214. At this time, the staff did not rotate the adjusting rod 28, and the steel pipe was not fixed.

[0054] During operation:

[0055] As Figures 2 to 6 shown, the staff rotates the adjusting rod 28 so that the adjusting teeth 29 correspond to the grooves on both sides of the adjusting passage groove 26. Subsequently, the staff pushes the adjusting working plate 25 towards the center of the sliding support plate 21. At this time, the adjusting teeth 29 slide inside the adjusting passage groove 26. While the adjusting rod 28 displaces towards the center of the cutting workbench 1 on the outer wall of the sliding support plate 21, the adjusting working plate 25 drives the first sliding block 24 to slide inside the first sliding groove 23, preventing the adjusting working plate 25 from shifting when sliding on the outer wall of the sliding support plate 21. When the adjusting rod 28 displaces, it drives the cross linkage block 210 to displace together. At this time, since the second connecting slider 219 fixedly connected to the side of the extension arc plate 213 close to the adjusting working plate 25 is restricted from displacing by the second sliding groove 217, the push connecting rod 211 extends in the vertical direction while the cross linkage block 210 displaces. While the push connecting rod 211 extends, the push connecting rod 211 causes the extension arc plate 213 to uniformly expand around the adjusting rod 28 through the push connecting block 212. At this time, the second connecting slider 219 slides inside the second sliding groove 217 in the direction away from the limit bottom plate 215. While the second connecting slider 219 slides, it drives the first connecting slider 218 and the sliding connecting rod 220 to displace together in the second sliding groove 217 in the direction away from the limit bottom plate 215. At the same time, the sliding of the second connecting slider 219 causes the first limiting spring 221 to be elastically compressed;

[0056] At this time, since the four extension arc plates 213 gradually expand around the center of the adjusting rod 28, and since the material of the rubber sleeve 214 is elastic rubber, the rubber sleeve 214 sleeved on the surface of the extension arc plate 213 is driven by the expansion of the four extension arc plates 213, and the inner wall of the rubber sleeve 214 is gradually expanded by the four extension arc plates 213 around the center of the adjusting rod 28. When the rubber sleeve 214 is expanded to fit the inside of the steel pipe, the staff rotates the adjusting rod 28 by 90 degrees and stops pushing the adjusting rod 28;

[0057] As Figure 7 and Figure 8As shown, the adjusting rod 28 is rotated by 90 degrees at this time. Consequently, the adjusting teeth 29 on the surface of the adjusting rod 28 are also rotated by 90 degrees. At this time, the staff stops pushing the adjusting rod 28 to displace, so that the relative positions of the adjusting teeth 29 and the adjusting limit groove 27 correspond. At this time, because the staff stops applying external force, the elastic extension of the first limit spring 221 is no longer restricted. Under the action of the elastic extension of the first limit spring 221, there is a tendency for the adjusting rod 28 to be displaced away from the center of the cutting workbench 1 through the stretching arc plate 213 and the first limit spring 221. However, since the relative positions of the adjusting teeth 29 and the adjusting limit groove 27 coincide at this time, the adjusting teeth 29 are clamped with the adjusting limit groove 27 through the elastic extension of the first limit spring 221, fixing the position of the adjusting rod 28. Consequently, the first limit spring 221 still remains in a state where its elastic extension is restricted;

[0058] At this time, the rubber sleeves 214 sleeved on the surfaces of the four stretching arc plates 213 are elastically stretched by the four stretching arc plates 213. Due to the material of the rubber sleeves 214, the friction generated between the rubber sleeves 214 and the steel pipe, and under the limiting action of the adjusting limit groove 27, the position of the steel pipe on the rubber sleeves 214 is fixed at this time. Further, the staff can perform subsequent cutting processing on the steel pipe, reducing the influence of external factors on the cutting accuracy of the steel pipe, ensuring the accuracy and consistency of the cutting line. The clamping of the inside of the steel pipe by the rubber sleeves 214 effectively reduces the vibration and deformation of the steel pipe during the cutting process, avoiding excessive or insufficient cutting during the cutting process due to unstable clamping, resulting in waste and loss during the cutting process. Further, the cutting cost is reduced, the generation of waste is reduced, and the problem of uneven cutting caused by the offset of the steel pipe due to the inability of the traditional clamping device to achieve uniform clamping of the steel pipe is avoided, thus affecting the cutting quality. The risk of accidental accidents such as calipers, cutter jams, and flying cutting debris caused by incorrect contact between the cutting blade and the steel pipe due to the offset of the steel pipe is reduced, ensuring the cutting efficiency of the steel pipe and avoiding harm to the operator caused by the offset of the steel pipe during cutting.

[0059] As Figures 4 to 8As shown, since the third sliding groove 31 is opened inside the adjusting working plate 25, when the adjusting working plate 25 drives the first sliding block 24 to slide inside the first sliding groove 23, the adjusting working plate 25 drives the third sliding groove 31 to slide together. Furthermore, when the staff positions the steel pipe for cutting according to the measuring ruler 4, when the staff moves the steel pipe to the position where cutting is required according to the measuring ruler 4, at this time, the staff lifts the fixed outer shell 36, and the fixed outer shell 36 rotates on the outer wall of the rotating fixed rod 35. The rotating fixed rod 35 drives the second sliding block 32 to slide into the fixed groove 22 through the limiting sliding rod 33. At this time, the second limiting spring 34 elastically extends, and the second sliding block 32 abuts against the inside of the fixed groove 22. Furthermore, at this time, the adjusting working plate 25 is fixed, avoiding the situation that due to the unclear marking line marked by the staff during cutting, the cutting position cannot be accurately determined during cutting, reducing the inaccurate manual marking, resulting in waste of steel pipes, increasing the consumption and cost of raw materials, solving the problem that due to the need for more time for manual measurement and marking, the production efficiency is low. The measuring ruler 4 provides a more accurate measurement standard. Compared with the traditional manual measurement and marking methods, the cutting accuracy and accuracy are improved, ensuring more stability during the steel pipe cutting process.
