Embodiment Construction
[0014] A telescoping pin rapid positioning device according to the present invention, see figure 1 : The device includes a hydraulic motor 1, a shaft 5, a cam 8, a push rod 9, a clamp body 4, a pin body 6 and a spring 7; the hydraulic motor 1 is connected to the shaft 5 through a coupling 2. The shaft 5 is arranged on the clamp body 4 through the bearing 3 . The cam 8 is arranged on the shaft 5 via a key 10 . The number of cams can be set as required, and in this embodiment, two cams are arranged on the shaft 5 . The lower end of the push rod 9 is adapted to the shape of the cam 8, and a groove 81 for limiting the movement of the push rod 9 is provided at the central position of the raised part of the cam 8. The groove 81 will stop the push rod 9 at that position. It will only move again under the action of external force. The upper end of the push rod 9 stretches out of the clamp body 4, and the pin body 6 is arranged on the top of the push rod 9; the spring 7 is sleeved o...
