[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A seamless steel pipe positioning and punching device, comprising a workbench body 1, two groups of first moving frames 2 are arranged on the top of the workbench body 1, the two groups of first moving frames 2 are connected by a second moving frame 3, a third moving frame 4 is arranged on the outer side of the second moving frame 3, a punching shaft 5 is arranged at one end of the third moving frame 4 away from the second moving frame 3, a plurality of groups of connecting seats 6 are arranged on the top of the workbench body 1 and at one end where the two groups of first moving frames 2 are close to each other, and a positioning and fixing component 7 is arranged at one end of the plurality of connecting seats 6 close to each other, and through the design of the first moving frame 2, the second moving frame 3 and the third moving frame 4, the punching shaft 5 can be displaced in all directions, so as to facilitate the punching of the steel pipe;

[0025] The positioning and fixing assembly 7 is used to position and fix steel pipes of different specifications.

[0026] Furthermore, the positioning and fixing component 7 is composed of a movable shell 8, a rotating disk 9, an arc groove 10, a movable rod 11, a limiting rod 12 and a driving screw 13. The movable shell 8 is located on the outer side of the connecting seat 6, and the rotating disk 9 is rotatably connected to the inside of the movable shell 8. Multiple groups of arc grooves 10 are all opened inside the rotating disk 9, and multiple groups of movable rods 11 are all slidably connected to the outer side of the rotating disk 9. The limiting rod 12 is fixedly connected to one end of the movable rod 11 away from the rotating disk 9, and the driving screw 13 is rotatably connected to one end of the connecting seat 6 close to the movable shell 8. When the steel pipe is perforated, the positioning and fixing component 7 can be used to conveniently position and fix the steel pipe, thereby facilitating the perforation of the steel pipe, and at the same time, steel pipes of different specifications can be positioned and fixed.

[0027] Among them, the moving rod 11 extends to the inside of the arc groove 10 and is provided with a fixed rod 14. The external structure size of the fixed rod 14 is designed to correspond to the internal structure size of the arc groove 10. The moving rod 11 is connected to the arc groove 10 through the fixed rod 14, and the fixed rod 14 and the arc groove 10 are slidably connected so that the moving rod 11 can be connected to the arc groove 10. When the rotating disk 9 rotates and drives multiple groups of arc grooves 10 to move, the fixed rod 14 can move, driving the moving rod 11 to move, so that the limiting rod 12 can move.

[0028] Secondly, a guide seat 15 is provided inside the moving shell 8 and on the outside of the moving rod 11. The internal structure size of the guide seat 15 is designed to correspond to the external structure size of the moving rod 11. The moving rod 11 is connected to the moving shell 8 through the guide seat 15. The moving rod 11 and the guide seat 15 are slidably connected so that the moving rod 11 can be connected to the moving shell 8. When the moving rod 11 is displaced, it can be guided by the guide seat 15 to prevent the moving rod 11 from being offset, which would affect the displacement of the limit rod 12.

[0029] Furthermore, a first thread groove 16 is opened inside the rotating disk 9, and the internal structure size of the first thread groove 16 is designed to correspond to the external structure size of the driving screw 13. The rotating disk 9 is connected to the driving screw 13 through the first thread groove 16. The first thread groove 16 and the driving screw 13 are threadedly connected, so that the rotating disk 9 can be connected to the driving screw 13. When the driving screw 13 rotates, the rotating disk 9 can be driven to rotate through the first thread groove 16.

[0030] Furthermore, both ends of the outer side of the movable shell 8 are rotatably connected with a threaded barrel 17, and a second thread groove 18 is opened inside the threaded barrel 17. The internal structure size of the second thread groove 18 is designed to correspond to the external structure size of the driving screw 13. The threaded barrel 17 is connected to the driving screw 13 through the second thread groove 18, and the second thread groove 18 is threadedly connected to the driving screw 13, so that the threaded barrel 17 can be connected to the driving screw 13, thereby enabling the movable shell 8 to be connected to the driving screw 13. When the driving screw 13 rotates, the second thread groove 18 can drive the threaded barrel 17 to move, so that the movable shell 8 can move.

[0031] Furthermore, the driving screw 13 extends to the interior of the connecting seat 6 and is fixedly connected to the driving end of the driving motor. A plurality of sliding rods 19 are provided at one end of the moving shell 8 close to the connecting seat 6. The sliding rods 19 are slidingly connected to the connecting seat 6 at one end away from the moving shell 8. Starting the driving motor can drive the driving screw 13 to rotate, and slidingly connect the sliding rods 19 to the connecting seat 6, so that the moving shell 8 can be connected to the connecting seat 6. When the moving shell 8 is displaced, it can be guided by the sliding rods 19 to prevent the moving shell 8 from being offset, which affects the positioning and fixation of the steel pipe.

[0032] In this embodiment, the implementation scenario is specifically as follows: in actual use, the steel pipe is placed on the outside of multiple groups of limit rods 12, and the driving motor is started. When the driving screw 13 rotates, the second thread groove 18 can drive the threaded barrel 17 to move, so that the movable shell 8 can be moved, and the limit rod 12 is moved to the inside of the steel pipe, driving the driving screw 13 to rotate. At the same time, when the driving screw 13 rotates, the first thread groove 16 can drive the rotating disk 9 to rotate. When the rotating disk 9 rotates and drives multiple groups of arc grooves 10 to move, the fixed rod 14 can be moved, and the moving rod 11 can be moved, so that the limit rod 12 can be moved, expanded outward, and contacted with the inner wall of the steel pipe to limit the steel pipe. Through the overall design, the steel pipe can be conveniently positioned and fixed, so that the steel pipe can be conveniently perforated. At the same time, steel pipes of different specifications can be positioned and fixed. Compared with the existing perforating device, the utility model can improve the overall practicality of the perforating device through design.
