When the height of the device rising is horizontal with the positioning surface of the clamping device of the machining center, the placing box 3 is pushed. When the placing box 3 cannot slide, the workpiece is located in the clamping device. The bottom of the workpiece, after the workpiece is clamped, the device is then restored to its original state, and the feeding is completed.

Working principle: When using the device, place the workpiece inside the placing box 3, then push the push rod 11, and then push the rear extrusion rod 6 to slide forward, thereby extruding the workpiece, and at the same time to the front side. The extrusion rod 6 is squeezed to make the spring 17 in a compressed state, and the two inclined rods 19 move forward in the placing box 3 while pushing the push rod 11. The surfaces of 19 pressurize the inner walls of the two chutes 18 respectively, so that the extrusion rods 6 on the left and right sides move relative to each other, thereby making the workpiece approach the vertical centerline of the placing box 3, and then with the push rod 11. When the extruding rods 6 on the left and right sides are in contact with the workpiece, the center point of the workpiece has been matched with the center point of the placing box 3 at this time.
