Specific embodiments

[0025] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0026] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] As Figures 1-7 shown, an inner bead cutting device includes a fixed plate 1 and a fixed seat 2. The fixed plate 1 is provided with a first guide rod 3 and a second guide rod 4. A first cutter assembly and a second cutter assembly are provided on the first guide rod 3 and the second guide rod 4. The first cutter assembly is connected with a first telescopic cylinder 5, and the second cutter assembly is connected with a second telescopic cylinder 6. The fixed seat 2 is arranged on the fixed plate 1, and a photoelectric switch 7 is arranged on the fixed seat 2.

[0028] A device for cutting internal welding ribs of the present utility model is provided with a photoelectric switch 7. The position of the internal welding rib 20 is detected by the photoelectric switch 7 to achieve precise positioning. When the photoelectric switch 7 detects the internal welding rib 20, the cutting tool assembly is driven by two telescopic cylinders to move up and down to cut off the internal welding rib 20, replacing traditional manual cutting, improving the cutting success rate, and reducing material waste.

[0029] It can be understood that in the present utility model, the photoelectric switch 7 is used to detect whether there is an internal welding rib 20 at the corresponding position height. When there is an internal welding rib 20 at the corresponding position height, the light beam emitted by the photoelectric switch 7 is reflected and received by the photoelectric switch 7.

[0030] As an implementation manner, the photoelectric switch 7, the first telescopic cylinder 5, and the second telescopic cylinder 6 can be electrically connected to the upper computer or the central control machine. When the photoelectric switch 7 detects that the emitted light beam is reflected, a feedback signal is sent to the upper computer or the central control machine, indicating that there is an internal welding rib 20 at the corresponding position height. After receiving the feedback signal sent by the photoelectric switch 7, the upper computer or the central control machine controls the first telescopic cylinder 5 and the second telescopic cylinder 6 to act to drive the cutting tool assembly to move up and down to cut off the internal welding rib 20.

[0031] Furthermore, the first cutting tool assembly can slide up and down along the first guiding rod 3 and the second guiding rod 4 under the drive of the first telescopic cylinder 5, and the second cutting tool assembly can slide up and down along the first guiding rod 3 and the second guiding rod 4 under the drive of the second telescopic cylinder 6.

[0032] The first guiding rod 3 and the second guiding rod 4 play a guiding role, so that the first cutting tool assembly and the second cutting tool assembly always remain on a stable cutting surface during the up and down movement.

[0033] Furthermore, the first cutting tool assembly includes a cutter fixing seat 82. A blade 9 is fixedly arranged on the cutter fixing seat 82. Guide holes 10 are provided at both ends of the cutter fixing seat 82. The first guiding rod 3 and the second guiding rod 4 respectively penetrate through the guide holes 10 at both ends of the cutter fixing seat 82. A copper sleeve 11 is provided between the guide holes 10, the cutter fixing seat 82, the first guiding rod 3, and the second guiding rod 4.

[0034] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, in an embodiment, the first cutting tool assembly is located at the upper position of the device, Figure 5 is an enlarged sectional view of the first cutting tool assembly. The second cutting tool assembly is located below the first cutting tool assembly. When cutting the internal welding rib 20, the first cutting tool assembly moves downward, and the second cutting tool assembly moves upward to cut the internal welding rib 20 located between the first cutting tool assembly and the second cutting tool assembly.

[0035] Further, the structure of the second cutter assembly is the same as that of the first cutter assembly, and the first cutter assembly and the second cutter assembly are arranged oppositely.

[0036] The structure of the second cutter assembly is the same as that of the first cutter assembly. The difference is that they are arranged oppositely and have different orientations. Therefore, the structure of the second cutter assembly will not be described in detail here.

[0037] Further, as Figure 1 shown, a chute 12 is provided on the fixed seat 2. The photoelectric switch 7 is connected to the chute 12, and the photoelectric switch 7 can slide along the chute 12. The chute 12 is arranged longitudinally.

[0038] It can be understood that the photoelectric switch 7 can slide along the chute 12, that is, the position height of the photoelectric switch 7 is adjusted. The diameters of the high-frequency welded pipes 19 are different, and the heights of the inner welded ribs 20 after scraping are also different, such as 219 pipes, 273 pipes, 660 pipes, etc. For example, when cutting the inner welded rib 20 of a 219 pipe or a 660 pipe, after arranging it in the state as Figure 7 shown, although the inner welded rib 20 is on the central axis of both the 219 pipe and the 660 pipe, due to the different diameters of the 219 pipe and the 660 pipe, the heights of the inner welded rib 20 are also different. When cutting the inner welded rib 20 of a 219 pipe or a 660 pipe, it is necessary to keep the inner welded rib 20 at a suitable position height for cutting. At this time, the precise control of the position of the inner welded rib 20 can be achieved through the photoelectric switch 7.

[0039] Further, as Figure 1 and Figure 2 shown, the device further includes a mounting plate 13. One ends of the first guiding rod 3 and the second guiding rod 4 are connected to the fixing plate 1, and the other ends of the first guiding rod 3 and the second guiding rod 4 are connected to the mounting plate 13. The first telescopic cylinder 5 is fixed on the mounting plate 13, and the second telescopic cylinder 6 is fixed on the fixing plate 1.

[0040] As Figure 4 and Figure 5 shown, the first telescopic cylinder 5 is provided with a telescopic rod 21. One end of the telescopic rod 21 is connected with a connecting block 22, and the connecting block 22 is connected to the cutter fixing seat 82. The first telescopic cylinder 5 drives the cutter fixing seat 82 to move up and down through the telescopic movement of the telescopic rod 21, thereby driving the entire first cutter assembly to move. The principle of the second telescopic cylinder 6 driving the second cutter assembly is the same as that of the first telescopic cylinder 5 driving the first cutter assembly, and will not be described in detail here.

[0041] As an implementation manner, mounting holes are provided at both ends of the first guiding rod 3 and the second guiding rod 4, and they can be connected to the fixing plate 1 and the mounting plate 13 respectively through screws.

[0042] Further, the device further includes a base 14, as Figure 6As shown, the base 14 includes a plurality of cross beams 15 and a plurality of support columns 16. The plurality of cross beams 15 surround to form a rectangle. The plurality of support columns 16 are connected to the cross beams 15. Casters are provided below the base 14, but not shown in the figure.

[0043] As Figure 1 , Figure 2 and Figure 6 shown, as an implementation manner, there are 8 cross beams 15 and 4 support columns 16. The 8 cross beams 15 are divided into two groups. The 4 cross beams 15 in the same group are connected end to end to form a rectangular frame. The two rectangular frames are arranged one above the other and are connected by 4 support columns 16. Two connecting plates 17 are provided on the upper rectangular frame.

[0044] Furthermore, the fixing plate 1 is installed on the base 14 through a plurality of adjusting lead screws 18.

[0045] As Figure 1 , Figure 2 and Figure 6 shown, there are 4 adjusting lead screws 18. The upper part of the adjusting lead screw 18 is connected to the fixing plate 1 through an adjusting bolt, and the lower end of the adjusting lead screw 18 is connected to the connecting plate 17. The adjusting lead screw 18 plays a role in supporting the fixing plate 1, and at the same time, the height of the fixing plate 1 can be adjusted by adjusting the adjusting bolt.

[0046] A device for cutting internal welding ribs of the present utility model is provided with a photoelectric switch. The position of the internal welding ribs is detected by the photoelectric switch to achieve precise positioning. When the photoelectric switch detects the internal welding ribs, the cutting tool assembly is driven by two telescopic cylinders to move up and down to cut the internal welding ribs, replacing the traditional manual cutting, improving the cutting success rate at the same time, and reducing material waste.
