[0014] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below with reference to the accompanying drawings.

[0015] like Figure 1-4As shown, the utility model dual-purpose tooling for internal thread and chamfering of slender steel pipes comprises a processing lathe 1; a main shaft 2 with a through hole in the middle is rotatably arranged on one side of the processing lathe 1; a motor 3 is arranged on one side of the main shaft 2 of the processing lathe 1; the motor 3 drives the main shaft 2 to rotate; a chuck 4 is fixedly arranged at one end of the main shaft 2; a through hole is arranged in the middle of the chuck 4 and is opposite to the through hole in the middle of the main shaft 2; a sliding track 5 is arranged on the processing lathe 1; a tool holder moving platform 6 is slidably arranged on one side of the chuck 4 on the sliding track 5; a chamfering tool 7 is arranged on the tool holder moving platform 6; the sliding track 5 A feeding device 8 is slidably arranged on one side of the tool holder moving platform 6; an internal thread cone 9 is arranged on the feeding device 8; a feeding table 10 is arranged on one side of the processing lathe 1; the feeding table 10 includes a feeding channel 11 arranged on the upper side; the feeding channel 11 is arranged relative to the main shaft 2; a cutting groove 1101 is arranged in the middle of the feeding channel 11; a cutting machine 12 is rotatably arranged on the feeding table 10 at the position of the cutting groove 1101; a first cylinder 13 is rotatably arranged on one side of the feeding table 10 relative to the cutting machine 12; a cylinder head of the first cylinder 13 is rotatably connected to the cutting machine 12.

[0016] Combination Figure 1-4 As shown, during use, the slender steel pipe is fed to the processing lathe 1 through the feeding table 10, and the steel pipe is cut into the required size through the cutting machine 12. The cut steel pipe is pushed into the through hole in the main shaft 2 by the subsequent steel pipe on the feeding channel 11, and then reaches the position of the chuck 4 and is fixed by the chuck 4. The motor 3 drives the main shaft 2 to rotate with the chuck 4 and the steel pipe, and the chamfering knife 7 set on the tool holder moving platform 6 performs internal and external chamfering operations on the steel pipe. The rear feeding device probes the internal thread cone 9 to a suitable length, so that the internal thread cone 9 taps the required thread on the inner wall of the steel pipe. Multiple operations such as steel pipe cutting, chamfering, and tapping can be completed by one-time feeding, which can significantly reduce the operating steps, increase the processing speed, save time, shorten the production cycle, and improve work efficiency. The one-time completion can avoid errors in the division of labor operations, and can improve the processing accuracy as a whole. The operation process is simplified, the operation difficulty is low, and the manual operation is convenient.

[0017] The feed channel 11 is provided with a second cylinder 14 above both sides of the cutting groove 1101; the second cylinder 14 head is provided with a fixed pressing block 15 downward relative to the feed channel 11. When the feed channel 11 of the feeding table 10 cuts the slender steel pipe, the required length cutting position is aligned with the cutting machine 12 relative to the cutting groove 1101, and the second cylinder 14 provided on both sides of the cutting groove 1101 is started. The cylinder head of the second cylinder 14 is pressed downward to make the fixed pressing block 15 press the steel pipe tightly, and then the first cylinder 13 is started to pull the cutting machine 12 down so that the cutting machine 12 cuts the steel pipe. The fixed pressing block 15 is used to firmly fix the steel pipe during the cutting process, which can significantly improve the cutting accuracy, prevent the steel pipe from shaking or shifting during the cutting process, and ensure that the cutting machine 12 can cut according to the cutting groove 1101, so that the cut steel pipe has a more precise and neat incision. At the same time, the firm fixation provided by the fixed pressing block 15 can also enhance the stability and safety of the cutting operation and protect manual safety.
