Detailed Description
The utility model will be described in detail by way of example with reference to the accompanying drawings, which form a part hereof, and in which it is to be understood that the described embodiments are by way of illustration only, and not by way of limitation.
As shown in fig. 1-3, an internal stay formula three-jaw centering fixture, including robot connecting plate 1, robot connecting plate 1 is connected with the robot through the ring flange, the one end that robot connecting plate 1 kept away from the robot is connected with fixture, still be provided with the buffer gear who is used for slowing down vibrations on the robot connecting plate 1, the robot system in this embodiment is not in the application scope of this patent, is the optional corollary equipment of this anchor clamps, and the event is no longer repeated.
The clamping mechanism comprises a clamping seat 2, a cylinder connecting seat 4 is arranged at the top of the clamping seat 2, a cylinder 5 is connected onto the cylinder connecting seat 4, the rod part of the cylinder 5 sequentially penetrates through the cylinder connecting seat 4 and the clamping seat 2 to extend downwards, a stretching shaft 6 is connected to the end part of the cylinder 5, three clamping jaws 7 are arranged on the outer side of the stretching shaft 6, the three clamping jaws 7 are distributed at equal intervals by taking the stretching shaft 6 as a circle center, the stretching shaft 6 is rotatably connected with the clamping jaws 7 through a supporting plate 8, the tops of the three clamping jaws 7 are rotatably connected with the bottom of the clamping seat 2 through a connecting plate 9, and the connecting plate 9 is favorable for keeping the parallel and stable clamps; the top of the clamping base 2 is also provided with a floating plate 3, and the floating plate 3 is fixedly connected with the clamping base 2 through a bolt.
