Description

[0002] Steel pipes, as a crucial basic material, occupy an indispensable position in numerous industrial sectors. In the construction industry, steel pipes are widely used for erecting scaffolding and constructing support systems for building structures, providing a stable framework for buildings. With rapid industrial development, the demand for steel pipes is constantly increasing, simultaneously placing higher requirements on their quality and processing precision. The quality of the steel pipe end face treatment is one of the key factors affecting the overall performance and service life of the steel pipe. Good end face treatment can ensure the sealing and reliability of steel pipe connections, reducing the risk of leakage.

[0003] Traditional methods for treating steel pipe ends, such as manual grinding, are cumbersome. The skill levels of different workers vary, and even the same worker cannot guarantee consistent results each time. This makes it difficult to achieve the required flatness and roughness of the steel pipe end face. When grinding manually, workers need to hold the grinding tools and it is difficult to fix the steel pipe, resulting in poor stability and low efficiency in the steel pipe end face grinding process.

[0004] Therefore, we have made improvements to this and proposed a CNC integrated machine for end face processing of steel pipes. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes a CNC integrated machine for end face processing of steel pipes, including a frame 1. A gearbox 2 is bolted to the left end of the upper end face of the frame 1. A three-jaw chuck 3 is fixedly connected to the output end of the gearbox 2. A first moving plate 4 is slidably connected to the frame 1. A first shifting mechanism 5 for shifting the first moving plate 4 is provided on the rear side of the frame 1. A first telescopic cylinder 6 is fixedly connected to the lower end face of the first moving plate 4. The driving end of the first telescopic cylinder 6 passes through the first moving plate 4 and is fixedly connected to a support frame 7. A second moving plate 8 is provided on the outer side of the first moving plate 4 and is slidably connected to the frame 1. A second shifting mechanism 9 for shifting the second moving plate 8 is provided on the front side of the frame 1. A second telescopic cylinder 10 is fixedly connected to the lower end face of the second moving plate 8. The driving end of the second telescopic cylinder 10 passes through the second moving plate 8 and is fixedly connected to a lifting plate 11. A grinding motor 12 is fixedly connected to the upper end face of the lifting plate 11. A connecting shaft 13 is fixedly connected to the driving end of the grinding motor 12. A mounting head 14 is fixedly connected to the end of the connecting shaft 13. A grinding wheel 15 is mounted on the mounting head 14. A nut 16 is provided on the outer side of the grinding wheel 15, and the nut 16 is threadedly connected to the mounting head 14. The three-jaw chuck 3 can quickly and accurately clamp the steel pipe by using the synchronous movement of the three jaws, ensuring the stability and coaxiality of the steel pipe during processing, which is convenient for subsequent end face processing operations. When the first telescopic cylinder 6 extends or retracts, it can drive the bearing frame 7 to make vertical lifting and lowering movements to adjust the height position of related components to adapt to the processing requirements of steel pipes of different specifications. When the second telescopic cylinder 10 extends or retracts, it can drive the lifting plate 11 to make vertical lifting and lowering movements, which can adjust the height of the grinding wheel 15 to facilitate the adaptation to steel pipes of different specifications. The grinding motor 12 drives the connecting shaft 13, the mounting head 14 and the grinding wheel 15 to rotate, and grinds the end face of the steel pipe. The nut 16 is used to fix the grinding wheel 15 to prevent it from loosening and falling off during operation, and to facilitate the subsequent replacement of the grinding wheel 15.

[0029] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the first shifting mechanism 5 further includes two first mounting seats 501 symmetrically fixed on the rear side wall of the frame 1. A first screw 502 is rotatably connected between the two first mounting seats 501. A first motor 503 is fixedly connected to the rear side wall of the frame 1. The driving end of the first motor 503 is fixedly connected to the shaft end of the first screw 502. A first shifting block 504 is threadedly connected to the first screw 502. The first shifting block 504 is fixedly connected to the first moving plate 4 through a first connecting plate 505. The first screw 502 is driven to rotate by the first motor 503. The rotation of the first screw 502 can cause the first shifting block 504 and the first connecting plate 505 to move laterally, thereby adjusting the position of the first moving plate 4 horizontally and supporting steel pipes of different lengths.

[0030] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the second shifting mechanism 9 further includes two second mounting seats 901 symmetrically fixed on the front side wall of the frame 1. A second screw 902 is rotatably connected between the two second mounting seats 901. A second motor 903 is fixedly connected to the front side wall of the frame 1. The driving end of the second motor 903 is fixedly connected to the shaft end of the second screw 902. A second shifting block 904 is threadedly connected to the second screw 902. The second shifting block 904 is fixedly connected to the second moving plate 8 through a second connecting plate 905. The second screw 902 is driven to rotate by the second motor 903. The rotation of the second screw 902 enables the second shifting block 904 to move laterally, which in turn enables the second shifting block 904 and the second connecting plate 905 to move laterally, thereby enabling the second moving plate 8 to move laterally. This allows for horizontal adjustment of the position of the grinding wheel 15, facilitating the grinding of the steel pipe end face.

[0031] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the input end of the gearbox 2 is further fixedly connected to a driven pulley 17, and a fixed seat 18 is fixedly connected to the side wall of the frame 1 near the driven pulley 17. A third motor 19 is fixedly connected to the upper end face of the fixed seat 18, and a driving pulley 20 is fixedly connected to the driving end of the third motor 19. The driving pulley 20 is connected to the driven pulley 17 through a belt 21. When the third motor 19 starts, it drives the driving pulley 20 to rotate, which drives the driven pulley 17 to rotate through the belt 21, thereby transmitting power to the gearbox 2 to provide power for the rotation of the three-jaw chuck 3.

[0032] like Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, a protective cover 22 is further provided on the outside of the belt 21. The protective cover 22 is detachably connected to the fixing seat 18 by bolts. The function of the protective cover 22 is to prevent accidental injury to personnel during the operation of the belt 21, and also to prevent dust, debris, etc. from entering the belt 21 transmission system, affecting the normal operation and service life of the belt 21. The detachable connection method facilitates the inspection and maintenance of the belt 21.

[0033] like Figure 1 and Figure 4As shown, in a preferred embodiment, based on the above method, the upper end face of the first moving plate 4 is further provided with two guide holes symmetrically opened, and each guide hole is provided with a guide rod 23. The top end of the guide rod 23 is fixedly connected to the lower end face of the support frame 7. The cooperation between the guide rod 23 and the guide hole plays a guiding role, ensuring the stability of the support frame 7 during the lifting process, preventing it from deviating, and improving the processing accuracy of the equipment.

[0034] Specifically, when using this CNC integrated machine for end-face processing of steel pipes: First, adjust the position of the first moving plate 4 and the height of the support frame 7 according to the specifications of the steel pipe. The first motor 503 drives the first screw 502 to rotate. The rotation of the first screw 502 enables the first shifting block 504 and the first connecting plate 505 to move laterally, moving the first moving plate 4 to a suitable position. Then, the first telescopic cylinder 6 drives the support frame 7 to rise to the target height, placing the steel pipe on the support frame 7 and inserting the unprocessed end of the steel pipe into the three-jaw chuck 3. The three-jaw chuck 3 is driven to clamp the steel pipe. Then, the second telescopic cylinder 10 drives the lifting plate 11 to rise to the target height, and the grinding motor 1... 2. Drive the connecting shaft 13, mounting head 14, and grinding wheel 15 to rotate. At the same time, the third motor 19 drives the drive pulley 20 to rotate, which drives the driven pulley 17 to rotate through the belt 21. This transmits power to the gearbox 2, causing the three-jaw chuck 3 and the steel pipe to rotate. The second motor 903 drives the second screw 902 to rotate. The rotation of the second screw 902 causes the second shift block 904 to move laterally, which in turn causes the second shift block 904 and the second connecting plate 905 to move laterally. This causes the second moving plate 8 to move laterally, allowing the grinding wheel 15 to move and contact the end face of the steel pipe, thereby grinding the end face of the steel pipe and improving processing efficiency.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
