The second transfer mechanism 7 is located at the right end of the rotary clamping mechanism 3.

The implementation steps are as follows: first, the first conveying mechanism 2 receives and conveys the pipe fitting of the previous process. The tubular is then pushed into the inner barrel 502 of the gripper assembly 5 by the pusher 1. The height position of the cutting member 112 on the sleeve member 111 is then adjusted according to the requirements of the groove depth of the pipe member. Then, the rotating device 6 is started to drive the outer cylinder 501 of the clamping assembly 5 to rotate to push the transmission part 503 to move, and further to push the clamping part 504 to move, in the process, the movement of the clamping part 504 is limited by the joint of the clamping part 504 and the inner cylinder 502, so that the clamping part 504 is forced to rotate to clamp the pipe with the joint of the clamping part 504 and the inner cylinder 502 as a central point, the rotation of the clamping part 504 is limited after the clamping part 504 clamps the pipe, and further the clamping part 504 is forced to drive the inner cylinder 502 and the pipe to synchronously rotate along the movement of the outer cylinder 501. Then, the displacement part 10 and the slide block 11 move in the front-back left-right free direction, so that the groove machining or cutting machining of any position of the pipe fitting is realized. Finally, after the pipe fitting is machined, the rotating device 6 is started again to rotate reversely to loosen the pipe fitting, meanwhile, the pushing device 1 is started again to push the unprocessed root pipe fitting into the inner cylinder 502 to abut against the machined pipe fitting, and the machined pipe fitting is pushed away from the inner cylinder 502 to enter the second conveying mechanism 7 to be conveyed to the next procedure.

As shown in fig. 14 and 15, the joint 91 has a concave portion 911 and a convex portion 912, and the concave portion 911 has a joint space. Projection 912 is connected to recess 911, projection 912 has a smaller volume than the engagement space, and projection 912 is relatively movable with respect to the engagement space. The contact piece 101 of the displacement portion 10 slides in the chute of the dust-escape portion 9 for movement, the engagement piece 91 in the chute sealing the chute. When the contact member 101 contacts with the joint member 91, the joint member 91 is forced to retract and move to provide a space for the contact member 101 to move, and when the contact member 101 does not contact with the joint member 91, the joint member 91 is reset under the elastic action of the telescopic member 92 to reseal the sliding chute, so that the situation that particles such as dust are accumulated in the sliding chute to cause the sliding of the displacement portion 10 to shake is avoided, and the processing of the pipe fitting is not facilitated.

At first, the top periphery of spout is in by half encirclement state, can avoid the dust to fall into the spout by the at utmost, prevents that particulate matter such as dust in the spout is too much, shakes when leading to displacement portion 10 to slide, is unfavorable for the pipe fitting processing. Secondly the curved dust portion 9 tops of keeping away can lead particulate matters such as dust, prevents that particulate matters such as dust from piling up on keeping away dust portion 9. Finally, the blocking surface at the side end of the sliding chute can block particles such as dust from falling into the sliding chute under the action of airflow to a certain extent.
