As shown in Figure 12 , the knurled nut 3 is provided with internal threads at the front part, and the rear end of the knurled nut 3 is sleeved on the rear end of the cutter transmission mechanism 2; after the cutting tool 12 and the cutter transmission mechanism 2 are inserted into the hollow through hole of the conical cutting mechanism 11 from back to front, the internal threads of the knurled nut 3 are connected with the rear threaded end 112 of the conical cutting mechanism 11; the feed amount of the cutting tool 12 is controlled by rotating the knurled nut 3 to ensure machining accuracy. The conical cutting mechanism 11 is further provided with an oil filler 113, and the oil filler 113 is through from outside to inside on the conical cutting mechanism 11 to the middle through hole of the conical cutting mechanism 11.

[0043] As shown in Figure 10 and 11 , the cutter transmission mechanism 2 comprises a limiting sleeve shaft 21 and a cutting shaft 22; the rear end of the limiting sleeve shaft 21 is connected with the front end of the driving joint 4; the front end of the limiting sleeve shaft 21 is connected with the rear end of the cutting shaft 22; the front end of the cutting shaft 22 is connected with the rear end of the cutting tool 12; and the rear side of the knurled nut 3 is sleeved on the limiting sleeve shaft 21 to fix the cutting tool 12 and ensure stability during machining. As shown in Figure 6 and Figure 7As shown, the cutting tool 12 includes a tool holder 121 and two inserts 122, the tool holder 121 is cylindrical, and two fixed screw holes are axially through the tool holder 121, and the tool holder 121 is fixed on the front end of the cutting shaft 22 by inserting the fixed bolts into the fixed screw holes; the two inserts 122 are symmetrically arranged on both sides of the front end of the tool holder 121, and a chip pocket 123 is arranged between the two inserts 122. The insert 122 includes an integral fixed part 1221 and a cutting part 1222, the fixed part 1221 has a fixed screw hole through the front and back directions, and the cutting part 1222 has a gradually inclined structure outward from back to front.

[0044] At the same time, in order to facilitate the fixing of the tool on the workbench during the machining process, the conical cutting mechanism 11 is further connected with a fixing plate 6. The outer surface of the knurled nut 3 has knurled lines to increase the friction between the fingers and the knurled nut when the operator holds it, making it easier for the operator to adjust forward and backward.

[0045] In addition, as shown in Figure 8 and Figure 9 As shown, the clamping chuck 5 includes a clamping nut 51 and a conical clamping block 52, the conical clamping block 52 includes an installation section 521 and a clamping section 522 axially connected with each other, and the diameter of the front end of the installation section 521 gradually decreases to the tail end of the clamping section 522, and a plurality of stretch strip grooves 523 are uniformly and axially arranged on the clamping section 522; the clamping nut 51 is internally threaded, the front end of the clamping nut 51 is sleeved on the installation section 521 of the conical clamping block 52, the rear end of the clamping nut 51 is sleeved on the front threaded end 111 of the conical cutting mechanism 11, and the through hole of the conical cutting mechanism 11 inside the front threaded end 111 is also conical. After the steel pipe 9 is inserted into the center hole of the conical clamping block 52, the clamping nut 51 is rotated clockwise, and the clamping nut 51 moves backward with the conical clamping block 52, when the outer surface of the conical clamping block 52 contacts with the conical structure of the through hole in the front threaded end 111 of the conical cutting mechanism 11, because a plurality of stretch strip grooves 523 are uniformly and axially arranged on the clamping section 522, the part of the clamping section 522 outside the stretch strip grooves 523 is gradually contracted inwardly by the extrusion of the inner wall of the conical through hole in the front threaded end 111 of the conical cutting mechanism 11, thereby tightly clamping the steel pipe 9 in the through hole.

Thus, the debris generated during the machining of the steel pipe can be blocked and collected, and finally the debris can be poured out from the oil filler 113 after the machining is completed and the steel pipe is removed.

[0047] As shown in Figure 13As shown, the driving joint 4 is connected with a hand crank 8 at the rear end, and the operator holds the hand crank 8 to rotate the blade 122 to process the tapered end of the steel pipe during processing. Of course, the rear end of the driving joint 4 can also be connected with a drill interface, and the rotation of the drill is used for driving. That is, it can be manually or electrically operated to be suitable for different working scenes.

[0048] The steel pipe conical processing tool is driven by hand or electricity to realize the conical processing of the end of the steel pipe, and the specific working principle is as follows:

[0049] First step. First, cut the pipe to the required length of the steel pipe 9, and remove the burrs at the end of the steel pipe 9.

[0050] Second step. Insert the steel pipe 9 into the center hole of the conical clamping block 52, and expose the end of a section, then rotate the clamping nut 51 clockwise, so that the clamping nut 51 moves backward with the conical clamping block 52, so that the clamping section 522 of the conical clamping block 52 clamps the steel pipe 9.

[0051] Third step. Then adjust the knurled nut 3 so that the cutting tool 12 and the end of the steel pipe 9 maintain appropriate spacing.

[0052] Fourth step. Then rotate the hand crank 8 clockwise (if the drill is used for driving, the drill is turned on), so that the cutting tool 12 gradually feeds to the end of the steel pipe 9 to gradually process the end of the steel pipe 9.

[0053] Fifth step. During the process of gradually feeding the cutting tool 12 to the end of the steel pipe 9, cutting oil is applied to the end of the steel pipe 9 through the oil inlet 113 to improve the cutting quality.

[0054] Sixth step. At the same time, during the process of gradually feeding the cutting tool 12 to the end of the steel pipe 9, the knurled nut 3 is occasionally rotated counterclockwise to prevent the formation of steps on the processed surface of the end of the steel pipe 9, and until the processing is completed.

[0055] In actual operation, first, the pipe material is sawed into a steel pipe 9 of a required length and burrs are removed, then the cutting tool 12 is installed on the tool driving mechanism 2, and the knurled nut 3 is rotated 2-3 turns to be fixed to the rear threaded end 112 of the conical cutting mechanism 11 to complete the preliminary installation. Then, the knurled nut 3 is continuously rotated clockwise until the distance from the front side 10mm of the rear threaded end 112, and the clamping conical clamp 52 is fixed by using the clamping nut 51. The conical cutting device 1 is fixed on the bench vice through the fixing plate 5 and clamped horizontally in the bench vice. The pipe end of the steel pipe 9 is clamped through the clamping chuck 5 and pushed into the opening of the conical cutting device 1. It is ensured that the pipe end of the steel pipe 9 and the cutting tool 12 maintain a distance of at least 5mm, and the pipe end of the steel pipe 9 should not contact the cutting tool 12. The clamping nut 51 is tightened. The knurled nut 3 is continuously rotated clockwise until the cutting tool approaches the pipe end, but does not contact the pipe end of the steel pipe 9. At this time, the knurled nut 3 is not continuously rotated. Then, cutting oil is applied to the pipe end of the steel pipe 9 and the cutting surface through the oil inlet 113 in the middle of the conical cutting mechanism 11. Finally, the hand crank 8 is quickly rotated clockwise or the electric drill is started to rotate clockwise, and the knurled nut 3 is slowly and uniformly rotated clockwise to complete the machining.

[0056] In this example, the steel pipe conical tool of the utility model can conveniently and quickly be used for conical and flat end machining of the steel pipe end to meet the pipeline connection or specific engineering requirements. The tool has the characteristics of convenient carrying, simple structure, small size, convenient operation, high machining precision, etc., and can be applied to on-site construction or temporary repair scenes. Compared with the traditional machine tool machining mode, the steel pipe conical tool has strong portability: convenient to carry, small size, and can be used at any time in the field or limited space, achieving on-site machining and machining anywhere that the traditional lathe cannot achieve. High adaptability: manual or electric operation can meet the steel pipe taper machining requirements of different scenes. Energy saving and environmental protection: no need for large equipment, reducing energy consumption, reducing carbon emissions, and no noise. High machining precision: optimized tool design ensures the quality of the machined surface and the precision of the thread. Wide application range: can be applied to pipeline installation, maintenance, manufacturing, etc., improving work efficiency and reducing cost, and compared with the traditional lathe machining, the structure is simple and easy to operate.

[0057] The above is only one preferred embodiment of the steel pipe conical tool of the utility model, and it should be noted that for ordinary skilled persons in the art, without departing from the creative concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model.
