[0047] Embodiment 2:

[0048] With reference to Figure 7 The difference between the embodiment and the embodiment 1 is that the end of the clamping mechanism 2 away from the pin pressing mechanism 1 is provided with a feeding mechanism 4 for feeding the pipe 102 to the clamping mechanism 2. The feeding mechanism 4 comprises a feeding box 41 and a carrier 42, the carrier 42 comprises a first plate 421 and a second plate 422, one end of the first plate 421 and one end of the second plate 422 are fixedly connected to form a "V" shape. The connection between the first plate 421 and the second plate 422 is rotationally connected with the rack 3. A plurality of first springs 43 and second springs 44 are connected between the carrier 42 and the rack 3, one end of the first spring 43 is fixedly connected with the outer wall of the first plate 421, and the other end is fixedly connected with the top of the rack 3. One end of the second spring 44 is fixedly connected with the outer wall of the second plate 422, and the other end is fixedly connected with the rack 3, so that the opening of the carrier 42 is arranged to face away from the rack 3, and is used for supporting the pipe 102.

[0049] The feeding box 41 is fixedly connected to the rack 3 and is inclined to the first plate 421. The feeding box 41 is provided with a feeding cavity 411, an inlet 412 and an outlet 413. The inlet 412 and the outlet 413 are communicated with the feeding cavity 411. The outlet 413 is arranged towards the first plate 421. The side of the first plate 421 close to the feeding box 41 is provided with a limiting plate 45. The inner wall of the feeding box 41 close to the rack 3 is provided with a plurality of slow-speed curved surfaces 414 for slowing down the rolling speed of the pipe 102, so that there is a gap between adjacent pipes 102, avoiding multiple pipes 102 falling into the bearing part 42 at the same time. When the opening of the bearing part 42 is upward, the limiting plate 45 abuts against the outlet 413 to limit the pipe 102 in the feeding box 41 from falling; when the bearing part 42 is inclined to the feeding box 41, the limiting plate 45 is separated from the outlet 413, and the pipe 102 rolls into the bearing part 42 from the outlet 413.

When the feeding cylinder 46 is contracted, the guide block 47 slides along the guide curved surface 424, forcing the first plate 421 to flip downward. The first plate 421 is separated from the outlet 413 of the feeding box 41, and the pipe 102 close to the outlet 413 rolls into the bearing part 42. In this process, the first spring 43 is compressed first and then stretched. The second spring 44 is stretched first and then compressed. The bearing part 42 can reset in time after flipping towards the feeding box 41, so as to ensure that only one pipe 102 falls into the bearing part 42 in one flipping. The feeding cylinder 46 pushes the pipe 102 in the bearing part 42 into the second positioning groove 214 for preliminary positioning, improving the degree of automation and the positioning accuracy of the pipe 102.
