Example Embodiment
[0039] Implementation mode one
[0040] Such as image 3 , 4 with Figure 4A As shown, the embodiment of the present invention proposes a three-jaw necking machine synchronized by a rack, which includes a support 1, a telescopic arm 2, a first and a second rotating arm 3, 4, and a first, a second, and a third jaw. 5, 6, 7, the first and second gear sets 8, 9 and the actuator cylinder 10. The telescopic arm 2 is connected to the support 1 movably up and down, and a rack 2a with a guide post is arranged under the telescopic arm 2. The first rotating arm 3 is rotatably connected to the support 1 through a first pin 1a, the second rotating arm 4 is rotatably connected to the support 1 through a second pin 1b, and the first , The two rotating arms 3 and 4 are symmetrically located on both sides of the telescopic arm 2. The first, second and third jaws 5, 6, 7 are connected to the first and second pivot arms 3, 4 and the telescopic arm 2 respectively. The first gear set 8 is connect...
Example Embodiment
[0054] Implementation mode two
[0055] The above embodiment is that the actuator cylinder 10 is placed horizontally, which directly drives the first and second rotating arms 3, 4 to rotate, and then through the matching relationship between the first and second gear sets 8, 9 and the rack with guide column 2a, the belt guide The column rack 2a moves. However, in this embodiment, the actuator cylinder 10 is placed vertically, which directly drives the rack with guide column 2a to move, and then through the matching relationship between the first and second gear sets 8, 9 and the rack with guide column 2a, the first , The second rotating arms 3 and 4 rotate. specifically is,
[0056] Such as Figure 7 , 8 with Figure 8A As shown, the actuator cylinder 10 has a cylinder rod flat head 10a and a cylinder barrel trunnion 10b, the cylinder rod flat head 10a is telescopically connected in the cylinder barrel trunnion 10b, and the actuator cylinder 10 is placed vertically, One of the c...
