The working process of the present invention is as follows. As shown inFIG.1andFIG.2, the raw material is placed on the first pallet group1-3and the second pallet group1-4, the slide table assembly3-4moves forward to the upper limit position on the Y axis of the numerical control machine tool, at this time, the position reached by the loading mechanism2is set to be point A. As shown inFIG.2, in the initial state, the first pallet group is facing the worktable. As shown inFIG.7andFIG.8, each pallet group is driven by a miniature cylinder1-15,1-16, which makes the two pallets of the first pallet group move forward, so that the raw material on the pallet reaches the bottom of point A. At this time, the electric motor2-1of the loading mechanism2works, so that the piston cylinder2-3pushes the piston rod2-6to move downward and then push the clamping device2-8(the specific structure used in the figure is pneumatic fingers) to move downward to clamp the raw material, and after the pneumatic fingers grab the raw material, the electric motor2-1starts again, pulls the pneumatic fingers to a specified height (just leave the pallet surface), and then the first pallet group1-3is reset. At this time, the slide table assembly3-4moves backward to point B (the position above the worktable), so that the pneumatic fingers are concentric with the turntable3-1in the turntable assembly. Then, the electric motor2-1starts again to unload the raw material on the turntable3-1of the numerical control machine tool, then the raw material is automatically positioned and clamped by the turntable3-1. Then, the loading mechanism2is reset, and at this time, the door of the numerical control machine tool is closed, and the numerical control machine tool processes the raw material. After the processing is completed, as shown inFIG.3, the turntable3-1releases the processed finished part, the door of the numerical control machine tool is opened, the slide table assembly3-4moves to point B, the electric motor2-1in the loading mechanism2starts, and the pneumatic fingers move down to grab the finished part, and then the pneumatic fingers rise to a specified height. At this time, the first pallet group moves to point A, and the slide table assembly moves forward to make the feeding assembly reach point A. The electric motor2-1in the loading mechanism2starts, the pneumatic fingers place the finished part on the pallet, and the pneumatic fingers and the pallet are reset. Next, the cylinder1-14installed under the feeding mechanism is activated, the connecting plate1-2is moved to the right so that the second pallet group1-4faces the worktable, and then the previous series of actions are repeated again.

As shown inFIG.5andFIG.6, in order to ensure the predetermined stroke of the connecting plate1-2and make the connecting plate1-2reach the preset position accurately, a limiter1-17is set on the base1-1.
