The push piece 2 in the knife tower clamping jaw is pushed out, the knife board moves backwards, the knife tower clamping jaw 14 aligns to a workpiece 42 at the material channel, the knife board moves leftwards, the workpiece 42 pushes the push piece 2 rightwards in the moving process, the push piece sensor 7 senses a signal and sends the signal to the push piece cylinder body 19, the push piece cylinder body 19 is loosened, and the clamping jaw 14 clamps the workpiece under the action of the compression spring 17. The slide plate moves rightwards to drive the tool turret clamping jaws 14 to leave a material channel and move forwards to the front of a main shaft 15, the tool turret clamping jaws 14 rotate at a high speed under the driving of an electric main shaft, when the rotating speed reaches the same speed as the main shaft of a machine tool, the tool turret clamping jaws 14 move leftwards to be aligned with the main shaft 15, a workpiece 42 is conveyed into a chuck opened by the machine tool, the clamping jaws in the tool turret clamping jaws 14 are opened, a workpiece 42 is tightly pushed in the chuck by a push sheet 2, the chuck clamping jaws clamp the workpiece 42, the tool turret clamping jaws 14 move rightwards to leave the main shaft 15, the rotating speed is reduced and the positioning is carried out, at the moment, the tool turret clamping jaws are used as a tool turret, and.

After the workpiece is machined, the rotating speed of the tool turret jaw 14 is increased, the workpiece on the main shaft of the machine tool is clamped in high-speed rotation, then the workpiece moves rightwards and moves forwards, the rotating speed is reduced, the jaw 14 is opened, the workpiece 42 is pushed away by the push piece 2, falls into the material receiving groove 45, and then slides into the material receiving box 44.

The invention can synchronously rotate with the main shaft of the machine tool at high speed to realize synchronous feeding and discharging of workpieces, thereby achieving the effects of shortening the processing beat and simplifying the structure of the machine tool.
