Detailed Embodiments

[0016] All features disclosed in this specification, or all steps in any method or process disclosed, except for mutually exclusive features and / or steps, can be combined in any way.

[0017] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically recited, can be replaced by other equivalent or similar - purpose alternative features. That is, unless specifically recited, each feature is only an example of a series of equivalent or similar features.

[0018] Such as Figures 1-4As shown in the figure, an adjustable pipe fitting commutation device, characterized by comprising a mounting bracket 1, an adjustable seat 2, a lifting rod 3, a gear 4, a rotating rod 6 and a clamp 7. Long strip holes 8 are opened on both sides of the adjustable seat 2. Bolts are arranged in the long strip holes 8 and the adjustable seat 2 is mounted on the mounting bracket 1 through the bolts. A telescopic cylinder 9 is fixedly mounted on one side of the adjustable seat 2. The end of the telescopic cylinder 9 is fixedly connected with a rack 5. A long strip convex block 10 is arranged on the rear side edge of the rack 5. A limit block 11 is fixedly mounted on one side of the adjustable seat 2. A plurality of limit card slots 12 are arranged on the limit block 11. The long strip convex block 10 is clamped in the limit card slots 12. A gear 4 is arranged at the front end of the adjustable seat 2. A bearing 13 is arranged at the connection position of the adjustable seat 2 and the gear 4 and the gear 4 is mounted through the bearing 13. A lifting rod 3 is movably penetrated through the middle of the gear 4. The bottom of the lifting rod 3 is fixedly connected with a rotating rod 6. A buffer rubber ring 14 is sleeved at the lower end of the lifting rod 3. A track 15 is arranged at the bottom of the rotating rod 6. Moving blocks 16 are arranged at both ends of the track 15 and are mounted on the track 15 through bolts. Clamps 7 are arranged on the moving blocks 16.

[0019] The gear 4 meshes with the rack 5; the clamp 7 is connected with a controller and the opening and closing of the clamp 7 is controlled through the controller; the telescopic cylinder 9 is connected with a controller and the telescopic movement of the telescopic cylinder 9 is controlled through the controller; the lifting rod 3 is connected with a cylinder and the lifting of the lifting rod 3 is controlled through the cylinder.

[0020] During the use process, when one end of the pipe fitting is turned and cut, the controller controls the lifting rod 3 to descend. After descending to a certain position, the clamp 7 clamps the pipe fitting. Then the lifting rod 3 rises back to the original position. Then the telescopic cylinder 9 controls the rack 5 to move a certain distance, so that the rack 5 drives the gear 4 to rotate 180 degrees. The gear 5 drives the lifting rod 3 and the rotating rod 6 to rotate 180 degrees in sequence. At this time, the pipe fitting on the clamp 7 is rotated 180 degrees to realize commutation. Then the controller controls the lifting rod 3 to descend and the clamp 7 releases to put down the pipe fitting to continue the turning and cutting process of the other end of the pipe fitting.

[0021] If it is necessary to adjust the front and rear positions of the adjustable seat 2, the bolts in the long strip holes 8 can be loosened, and the front and rear positions of the adjustable seat 2 can be adjusted according to needs. Then the bolts can be tightened. If it is necessary to adjust the distance between the left and right clamps 7, after loosening the bolts, the positions of the moving blocks 16 can be adjusted. Then the bolts can be tightened.

[0022] This design is ingenious. The adjusting seat 2 can adjust its position back and forth on the mounting frame 1 as needed, and can adjust the distance between the two clamping hands 7 as required to adapt to different types of pipe fittings, making the pipe fittings more stable and less likely to shake when rotating and changing directions; the setting of the buffer rubber ring 14 reduces the jitter caused by collisions when the lifting rod 3 stops rising, thereby reducing the phenomenon of pipe fitting jitter; the setting of the gear 4, the rack 5 and the telescopic cylinder 9 has a simple structure and low manufacturing cost; changing the direction of the pipe fitting can realize turning and cutting the two ends of the pipe fitting on one device, saving equipment costs, realizing automation, and making production more convenient.

[0023] The utility model is not limited to the specific embodiments described above. The utility model extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
