Round steel pipes, in particular, are widely used in our industrial production. The rapid and efficient processing of round pipes is a crucial challenge that must be overcome to improve production efficiency. Some steel pipes are processed into bends or straight sections. During production, these pipes need to be cut transversely according to the required length. Currently, steel pipe cutting is done directly on a sawing machine using clamps such as pads and jigs to first position the pipe, then using a measuring tool to measure and mark the cutting position on the flange, and finally cutting with a saw blade. However, the current steel pipe cutting method is cumbersome, requires high measurement accuracy, is inconvenient to adjust, and results in low precision. It often leads to scrapped pipes due to excessive sawing, resulting in low work efficiency and affecting the final precision and quality of the product. Utility Model Content

The support base is provided with a scale extending along the moving direction of the sliding plate, and the sliding plate is provided with an indicator pointing to the scale. The indicator is in the shape of an arrow.

[0005] As a preferred embodiment, the sawing machine has a kerf strip that cooperates with the saw blade, the clamping opening is located on one side of the kerf strip, and the limiting plate is located on the other side of the kerf strip. The limiting plate is arranged opposite to or offset from the clamping opening.

[0006] As a preferred embodiment, the length extension direction of the limiting plate is parallel to the length extension direction of the cutting strip, the support extends a set length along the moving direction of the sliding plate and extends out of the sawing machine, and the length extension direction of the support is perpendicular to the length extension direction of the limiting plate.

[0007] As a preferred embodiment, the sawing machine is provided with an installation groove extending along the length direction of the limiting plate, and one end of the support base is provided with an installation slider connected to the installation groove.

[0008] As a preferred embodiment, the mounting slider is provided with multiple connecting holes, and the support is fixed to the saw by fastening the fastener through the connecting holes in the mounting groove. The mounting groove is a T-shaped groove structure.

[0009] As a preferred embodiment, the support base is provided with a guide rail extending in the same direction as it, and the bottom of the sliding plate is provided with a guide slider that is slidably connected to the guide rail.

[0010] As a preferred embodiment, the adjustment assembly includes an adjustment nut disposed at the bottom of the sliding plate, an adjustment screw extending along the length direction of the support and connected to the adjustment nut, and a positioning assembly disposed on the support and forming a positioning rotational engagement with the adjustment screw.

[0011] As a preferred embodiment, the positioning assembly includes two positioning bearings disposed opposite to each other on the support base, with both ends of the adjusting screw connected to the two positioning bearings respectively, and one end of the adjusting screw extending out of one of the positioning bearings.

[0012] As a preferred embodiment, the clamping mechanism includes two clamping blocks that are relatively movable on the sawing machine, and two clamping grooves that are respectively disposed opposite to the two clamping blocks, and the two clamping grooves are joined together to form a clamping opening for clamping the steel pipe, wherein the clamping groove is a V-shaped groove or an arc-shaped groove.

[0013] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0014] 1. The pipe-cutting fixture provided by this utility model directly clamps the steel pipe through the clamping port of the clamping mechanism, and limits the extension length of the steel pipe with the limiting plate of the limiting mechanism. No additional marking is required, achieving rapid positioning, greatly simplifying the operation process, and reducing positioning time. The fixture can directly read the length of the steel pipe to be cut by cooperating with the scale on the support base and the indicator on the sliding plate, achieving accurate measurement, reducing manual measurement errors, ensuring the accuracy of the steel pipe cutting length, and reducing the scrap rate caused by dimensional errors. The pipe-cutting fixture using this technical solution simplifies the operation process, facilitates positioning and adjustment, and improves cutting accuracy, thereby significantly shortening the processing time of a single steel pipe, better controlling product quality and optimizing the process, efficiently adapting to the processing and production of multi-specification steel pipes, significantly improving work efficiency, and reducing overall production costs.

[0015] 2. In the pipe sawing fixture provided by this utility model, the position of the limiting plate can be quickly and accurately adjusted by the cooperation of the adjusting components and the scale. During operation, simply pass the steel pipe through the clamping opening and let its end abut against the limiting plate to ensure that the length of the cut steel pipe meets the requirements. Then, the operator only needs to clamp the steel pipe with the clamping mechanism to start cutting. The adjustment is intuitive and convenient, which greatly simplifies the process and reduces the requirements for the operator's skills and experience. This structural setting, with the dual constraints of the clamping mechanism and the limiting mechanism, ensures the rigidity and stability of the cutting process, avoids the steel pipe shaking during the cutting process, and achieves digital and high-precision setting of the cutting length by adjusting the specific position of the limiting plate with the precise scale. This significantly improves the cutting accuracy, efficiency, stability and product consistency, while reducing the difficulty of operation, labor intensity, scrap rate and overall cost.

[0016] 3. In the pipe sawing fixture provided by this utility model, the support seat extends along the moving direction of the sliding plate and extends out of the side of the sawing machine, breaking through the space limitation of the sawing machine body and providing a longer stroke for the movement adjustment of the sliding plate. According to the support seat, it is connected to the installation groove set in the sawing machine through the installation slider, so that the support seat can be flexibly adjusted on the sawing machine along the length direction of the limiting plate. This can adapt to different sawing machine table layouts and facilitate the quick installation of the fixture on the sawing machine.

[0017] 4. In the pipe sawing fixture provided by this utility model, the cooperation between the guide rail and the guide slider provides a clear and stable movement trajectory for the sliding plate, ensuring that the sliding plate can only move linearly along the rail direction, avoiding lateral or torsional offset due to adjustment or vibration. When adjusting the position of the limiting plate, the screw transmission structure of the adjusting screw and the adjusting nut is used. The worker can drive the sliding plate and the limiting plate to move in a linear bidirectional manner by rotating the adjusting screw, which can realize the fine adjustment of the position of the sliding plate and the limiting plate, meet the length requirements of high-precision steel pipe cutting, and use the self-locking characteristic of the screw to ensure the stability of the position of the limiting plate during the cutting process.

[0028] Example

[0029] This embodiment provides, as follows: Figure 1-5 An adjustable pipe sawing fixture is shown, installed on a sawing machine 9. It includes a clamping mechanism 1 and a limiting mechanism respectively disposed on both sides of the saw blade 91 of the sawing machine 9. The clamping mechanism 1 has a clamping port 11 for clamping the steel pipe. The limiting mechanism includes a support base 2 installed on the sawing machine 9 and a sliding plate 3 movably disposed on the support base 2, and an adjusting component 7 disposed between the sliding plate 3 and the support base 2. The sliding plate 3 is provided with a limiting plate 4 facing the clamping port 11, so that the steel pipe is restricted by the limiting plate 4 after passing through the clamping port 11. The sliding plate 3 drives the limiting plate 4 to move closer to or away from the clamping port 11 under the drive of the adjusting component 7, and maintains a relatively locked position after coming to rest. The support base 2 is provided with a scale 5 extending along the moving direction of the sliding plate 3, and the sliding plate 3 is provided with an indicator 6 pointing to the scale 5.

[0030] The above-described implementation method is the core technical solution of this embodiment. The above-described pipe sawing fixture directly clamps the steel pipe through the clamping port 11 of the clamping mechanism 1, and limits the extension length of the steel pipe with the limiting plate 4 of the limiting mechanism. No additional marking is required, which realizes rapid positioning, greatly simplifies the operation process, and reduces positioning time. The fixture can directly read the length of the steel pipe to be cut by cooperating with the scale 5 on the support base 2 and the indicator 6 on the sliding plate 3, realizing accurate measurement, reducing manual measurement error, ensuring the accuracy of the steel pipe cutting length, and reducing the scrap rate caused by dimensional error. The pipe sawing fixture using this technical solution simplifies the operation process, facilitates positioning and adjustment, and improves cutting accuracy, thereby greatly shortening the processing time of a single steel pipe, better controlling product quality and optimizing the process, efficiently adapting to the processing and production of multi-specification steel pipes, significantly improving work efficiency, and reducing overall production costs.

[0031] like Figure 1-2As shown, the sawing machine 9 has a slit strip 92 that cooperates with the saw blade 91. The clamping opening 11 is located on one side of the slit strip 92, and the limiting plate 4 is located on the other side of the slit strip 92. The limiting plate 4 is arranged opposite to or offset from the clamping opening 11. This design can meet the cutting requirements of straight or curved pipes. The distance from the limiting plate 4 to the slit strip 92 is the cutting distance for the steel pipe.

[0032] In a further preferred configuration, the length extension direction of the limiting plate 4 is parallel to the length extension direction of the cutting strip 92. The support base 2 extends a predetermined length along the moving direction of the sliding plate 3 and extends out of one side of the sawing machine 9. This installation allows the support base 2 to overcome the spatial limitations of the sawing machine 9 body, providing a longer stroke for the movement adjustment of the sliding plate 3. The length extension direction of the support base 2 is perpendicular to the length extension direction of the limiting plate 4. The sawing machine 9 is provided with an installation groove 93 extending along the length direction of the limiting plate 4. One end of the support base 2 is provided with an installation slider 8 connected to the installation groove 93. The installation slider 8 is fixed to the support base 2 by bolts. The advantage of this installation design is that the support base 2 is connected to the installation groove 93 through the installation slider 8, allowing... The support base 2 can be flexibly adjusted along the length of the limiting plate 4 on the sawing machine, thus adapting to different sawing machine table layouts and facilitating quick installation of the tooling on the sawing machine. To ensure the reliability of the support base 2's installation on the sawing machine, the mounting slider 8 is provided with multiple connecting holes 81. The support base 2 is fixed to the sawing machine 9 by fastening the fastener through the connecting holes 81 into the mounting groove 93. The mounting groove 93 is a T-shaped groove structure, and the mounting slider 8 can be designed accordingly as a T-shaped slider structure. The fastener is a bolt that abuts against the mounting groove 93. The friction generated by tightening the bolt firmly fixes the support base 2 to the sawing machine. This fastening method is reliable and can effectively resist vibration and impact during cutting, keeping the relative position between the support base and the sawing machine unchanged, resulting in good installation stability.

[0033] The following is combined Figure 1-5 The specific settings for adjustment component 7 are explained in detail below:

[0034] The support base 2 is provided with a guide rail 31 extending in the same direction as it. The bottom of the sliding plate 3 is provided with a guide slider 32 that is slidably connected to the guide rail 31. The cooperation between the guide rail 31 and the guide slider 32 provides a clear and stable movement trajectory for the sliding plate 3, ensuring that the sliding plate 3 can only move linearly along the rail direction, and avoiding lateral or torsional offset due to adjustment or vibration. The adjustment assembly 7 includes an adjustment nut 72 disposed at the bottom of the sliding plate 3, an adjustment screw 71 extending along the length of the support 2 and connected to the adjustment nut 72, and a positioning assembly disposed on the support 2 and forming a positioning rotational engagement with the adjustment screw 71. The positioning assembly includes two positioning bearings 73 disposed opposite to each other on the support 2. The two ends of the adjustment screw are respectively connected to the two positioning bearings 73, and one end of the adjustment screw extends out of one of the positioning bearings. When adjusting the position of the limiting plate 4, the worker can drive the sliding plate 3 and the limiting plate 4 to move bidirectionally along the guide rail by rotating the adjustment screw (manually or with external power) through the helical transmission structure of the adjustment screw and the adjustment nut 72. This enables fine adjustment of the position of the sliding plate 3 and the limiting plate 4, meets the length requirements of high-precision steel pipe cutting, and ensures the stability of the position of the limiting plate during the cutting process by utilizing the self-locking characteristic of the threaded screw.

[0035] Although the aforementioned adjusting component 7 preferably uses a threaded screw adjustment method, other methods can obviously be used, such as a gear adjustment structure. The specific configuration is as follows: a rack extending along the length of the guide rail 31 is provided at the bottom of the sliding plate 3, and a gear assembly cooperating with the rack is provided on the support base 2. The gear assembly can be used with an operating shaft or an external drive motor. In this configuration, the sliding plate 3 achieves motion transmission through the gear transmission structure, which can also serve to adjust the installation position of the limiting plate. Those skilled in the art can choose the specific configuration of the adjusting component based on the above description; other equivalent methods will not be elaborated upon here.

[0036] In this embodiment, reference Figure 2The clamping mechanism 1 includes two clamping blocks 12 that are relatively movable on the sawing machine 9, and two clamping grooves that are respectively arranged opposite to the two clamping blocks 12. The two clamping grooves are joined together to form a clamping opening 11 for clamping the steel pipe. The clamping groove is a V-shaped groove or an arc-shaped groove. The V-shaped groove contacts the steel pipe through two inclined surfaces, and the arc-shaped groove contacts the steel pipe through an arc-shaped surface. Both can distribute the clamping force to a larger contact area, reduce the pressure per unit area, and avoid damage or deformation of the steel pipe surface due to excessive local force. At the same time, it reduces the wear of the clamping point and extends the service life. With this structure, the two clamping blocks 12 are designed to move relative to each other through a driving cylinder. With the automatic centering characteristics of the V-shaped groove or arc-shaped groove, the worker only needs to put the steel pipe into the clamping area and start the clamping action to complete the centering and clamping. There is no need to manually and repeatedly adjust the position of the steel pipe, reducing auxiliary operation time and improving cutting efficiency.

[0037] In summary, the pipe sawing fixture of this embodiment can quickly and accurately adjust the position of the limiting plate 4 to adapt to different cutting length requirements through the cooperation of the adjusting component 7 and the scale 5. During operation, simply pass the steel pipe through the clamping port 11 and let its end abut against the limiting plate 4 to ensure that the cut steel pipe length meets the requirements. Then, the operator only needs to clamp the steel pipe with the clamping mechanism 1 to start cutting. The adjustment is intuitive and convenient, which greatly simplifies the process and reduces the requirements for the operator's skills and experience. This structural setting, with the dual constraints of the clamping mechanism 1 and the limiting mechanism, ensures the rigidity and stability of the cutting process, avoids the steel pipe shaking during the cutting process, and achieves digital and high-precision setting of the cutting length by adjusting the specific position of the limiting plate 4 with the precise scale 5. This significantly improves the cutting accuracy, efficiency, stability and product consistency, while reducing the difficulty of operation, labor intensity, scrap rate and overall cost.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
