The L-shaped connecting plate 1 is provided with a movable groove 10 on the top surface of the horizontal end, and a T-shaped placing table 13 for placing parts is arranged in the movable groove 10. The vertical end of the T-shaped placing table 13 extends into the movable groove 10, and a pushing component for driving the movement is arranged in the movable groove 10. Clamping components for clamping parts are arranged on both sides of the top surface of the horizontal end of the T-shaped placing table 13. By placing the parts on the clamping components, as the clamping components are continuously moved, the process of drilling, expanding and tapping the parts is realized. Each step can be controlled individually by the electric push rod 3, so that specific parts can be processed separately, which improves practicality and reduces production costs.

[0021] Reference Figure 2 The moving assembly includes a guide rod 4 and a first lead screw 8.

One end of the moving plate 2 extending into the mounting groove 5 is slidably sleeved on the guide rod 4, and the other end is threadedly connected to the first lead screw 8. A first motor 9 connected to the first lead screw 8 is fixedly installed on the top surface of the vertical end of the L-shaped moving plate 2. The first lead screw 8 is driven to rotate by the rotation of the first motor 9, so that the moving plate 2 moves along the vertical end of the L-shaped connecting plate 1.

[0022] Reference Figure 2The pushing component includes a second lead screw 12, which is rotatably installed in the movable groove 10. The vertical end of the T-shaped placing table 13 extends into the movable groove 10 and is threadedly sleeved on the second lead screw 12.
