Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a steel pipe processing and drilling device. Background Art

[0002] Steel pipe processing drilling devices play an important role in improving processing efficiency, ensuring processing accuracy, reducing labor costs, improving processing quality, adapting to steel pipes of different specifications, ensuring safety, reducing scrap rate, improving automation, facilitating maintenance, and being environmentally friendly and energy-saving.

[0003] Although current technology has many advantages, the disadvantage of current technology is that after the hole-turning device drills holes in steel pipes from large to small diameters, some debris will remain inside the steel pipe. The presence of iron filings will destroy the flatness of the steel pipe surface, and then reduce the adhesion of the coating in subsequent work, making the coating unable to be evenly distributed or even falling off. Uneven coating or falling off will cause the steel pipe to be exposed to a corrosive environment, reducing the anti-corrosion performance and the service life of the equipment. At the same time, after the product is installed on current equipment, the origin of the drilling device needs to be in a straight line with the origin of the product, which requires manual adjustment and searching by the operator, reducing work efficiency and extending the production cycle.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 and Figure 6As shown, the utility model provides a technical solution: a steel pipe processing drilling device, comprising: a workbench 1, the outer surface of the workbench 1 is fixedly connected to a support frame 2, the top of the support frame 2 is fixedly connected to a motor 3, the motor 3 is provided with a rotating shaft 5 through a coupling, the outer surface of the rotating shaft 5 is fixedly connected to a support plate 4 on the side close to the motor 3, the outer surface of the rotating shaft 5 is provided with a plurality of notches 11, the inner surfaces of the plurality of notches 11 are each provided with two notches 2 12, the inner surfaces of the plurality of notches 2 12 are each movably embedded with a telescopic rod 13, and the outer surfaces of the plurality of telescopic rods 13 are movably sleeved There are springs 14, multiple scrapers 15 are fixedly connected to the outer surfaces of multiple telescopic rods 13, multiple springs 14 are fixedly connected to the inner surfaces of multiple slots 11, multiple springs 14 are fixedly connected to the outer surfaces of multiple scrapers 15, the support plate 4 is fixedly connected to the top of the workbench 1, the outer surface of the rotating shaft 5 is provided with a pipe 6, the top of the workbench 1 is provided with a slide groove 7, and the inner surface of the slide groove 7 is provided with a positioning mechanism, which improves the adhesion of the coating in subsequent work, makes the coating more evenly distributed to a certain extent, improves the anti-corrosion performance to a certain extent, and improves the service life of the equipment.

[0023] like Figure 5 and Figure 7 As shown, two hydraulic cylinders 16 are fixedly connected to the bottom of the workbench 1, and telescopic blocks 17 are fixedly connected to the tops of the two hydraulic cylinders 16. A slot three 18 is provided on one side of the workbench 1 close to the two telescopic blocks 17. Two positioning rods 19 are fixedly installed on the inner surfaces of the two slots 18. Arc blocks 20 are movably sleeved on the outer surfaces of the multiple positioning rods 19. Pulleys 21 are provided on the outer surfaces of both ends of the two telescopic blocks 17 and the multiple arc blocks 20 through pins, which avoids manual adjustment and searching by the operator, improves work efficiency, and shortens the production cycle.

[0024] like Figure 1-4 and Figure 6 As shown, the positioning mechanism includes a positioning block 8, which is movably embedded in the inner surface of the slide groove 7, and a threaded rod 9 is movably embedded in the inner surface of the positioning block 8. The threaded rod 9 is movably embedded in the inner surface of the workbench 1, and a handle 10 is fixedly connected to the outer surface of the threaded rod 9. The slide groove 7 can limit the moving trajectory of the positioning block 8, thereby avoiding the derailment of the positioning block 8 and affecting the use of the equipment.

[0025] like Figure 7 As shown, the two telescopic blocks 17 are movably embedded in the inner surfaces of the two slots 18 , and the slots 18 can provide a good working environment for the telescopic blocks 17 .

[0026] Working principle: This equipment is a steel pipe processing and drilling device. When in use, first put the pipe 6 on the rotating shaft 5, so that the scraper 15 fits with the inner wall of the pipe 6, and then start the two hydraulic cylinders 16 at the same time. The two hydraulic cylinders 16 move the telescopic blocks 17 in the two slots 18 upward. Due to the special shape of the arc block 20, the arc block 20 makes a circular motion with the positioning rod 19 as the center, and then the pulley 21 fits with the surface of the steel pipe. Because multiple pulleys 21 contact the pipe 6 from different directions and squeeze the pipe 6, the center point of the pipe 6 is positioned, avoiding manual adjustment and finding the center point of the steel pipe. Then manually rotate the handle 10 so that the handle 10 drives the positioning block 8 to move on the inner surface of the slide groove 7 through the threaded rod 9, so that the positioning block 8 positions the rotating shaft 5, and then the support plate 4 and the positioning block 8 can support the rotating shaft 5.

[0027] After the drilling is completed, the motor 3 on the support frame 2 is started, and the workbench 1 can support the support frame 2. The motor 3 drives the rotating shaft 5 to rotate through the coupling. There is a certain gap in the connection between the coupling and the rotating shaft 5, so that the rotating shaft 5 can be tilted at a certain small angle when it is not rotating, which is convenient for installing the pipe 6. The rotating shaft 5 indirectly drives the scraper 15 to rotate on the inner surface of the pipe 6 to clean the inner surface of the pipe 6. When cleaning the inner wall of the pipe 6, because the diameter of the pipe 6 gradually changes, and then when the rotating shaft 5 changes the distance from the inner wall of the pipe 6, the telescopic rod 13 will be telescoped on the inner surface of the slot 2 12, and the spring 14 in the slot 1 11 will also telescope, so that the scraper 15 can always fit with the pipe 6, and then the scraper 15 can clean out the iron filings inside the pipe 6.
