The outer collar 10 moves downward. When the movement occurs, the right cross bar 21 on the right side is driven to move downward, and when the right cross bar 21 moves downward, it drives the right vertical bar 22 at the bottom of its right end to move downward, so that the positioning baffle 47 at the bottom end of the right vertical bar 22 moves downward accordingly. When the positioning baffle 47 moves downward, it first contacts the workbench, at which time the positioning baffle 47 stops moving, and the connecting block 48 and the slide groove 49 on its outer side slide toward each other, so that the spring 50 is compressed, and a downward pressure is exerted on the positioning baffle 47 to fix the positioning baffle 47. When punching, the right side of the fixture 3 is engaged with the positioning baffle 47, so that the fixture 3 and the workpiece 4 can be fully and accurately positioned when punching, so as to achieve accurate punching of the workpiece 4 and improve the processing accuracy.

[0032] When the outer collar 10 moves downward, it drives the left folding rod 13 downward, so that the upper collar 14 at the other end of the left folding rod 13 moves downward. When the upper collar 14 moves downward, it drives the threaded rod 15 threadedly connected thereto to start rotating. When the threaded rod 15 rotates, it drives the movable rack 19 meshing therewith to move rightward in the horizontal direction. Conversely, the movable rack 19 moves leftward. When the movable rack 19 moves rightward, it drives the loading baffle 20 at the left end and the lower connecting rod 28 to move leftward, so that the loading baffle 20 pushes the workpiece 4 and the fixture 3 on the right side to move rightward, thereby realizing synchronous loading during drilling and improving processing efficiency. During the movement, the left side of the fixture 3 engages with the loading baffle 20, so that the fixture 3 and the workpiece 4 can be further fixed, thereby fully improving the processing accuracy.

[0033] When the movable rod 38 moves downward, it drives the liquid storage cylinder 39 downward. When the liquid storage cylinder 39 moves downward, it drives the cooling oil output pipe 40 and the valve 41 at the bottom to move downward. When the valve 41 moves downward, it drives the lever switch 43 downward. When the lever switch 43 moves downward, it contacts the block 44 and is pushed upward, so that the lever switch 43 is pushed upward, the valve 41 is opened, and the cooling oil is sprayed along the universal nozzle 42 at the bottom to cool and lubricate the workpiece 4 and the drill bit 12. When the drilling is completed, the valve 41 moves in the opposite direction, so that the lever switch 43 is pushed upward and closed, and the cooling oil automatically stops spraying, thereby effectively reducing the waste of cooling oil. When drilling, the feeding baffle 20 is located at the rightmost end. At this time, the position of the lower connecting rod 28 is located at the rightmost end, and the cleaning rod 27 is located at the rightmost side of the surface of the filter plate 26. The cooling oil and waste materials during processing are sprayed along the universal nozzle 42. The overflow hole 24 flows into the interior of the filter bin 25, and the waste in the cooling oil is filtered through the filter plate 26 and filtered to the surface of the filter plate 26. When the processing is completed, the movable rack 19 moves to the left, driving the lower connecting rod 28 to move to the left, so that the cleaning rod 27 moves to the left accordingly. During the movement, the cleaning rod 27 cleans the waste on the surface of the filter plate 26 into the slot 29 on the left side of the filter plate 26, so that the waste is collected in the collecting tank 30. The remaining coolant in the collecting tank 30 is filtered through the filter screen and flows into the filter bin 25 again along the inclined hole 31 at the bottom, thereby realizing the synchronous and automatic collection of the waste on the surface of the filter plate 26 and avoiding the filter plate 26 from being blocked; the filtered cooling oil flows into the liquid pump 34 along the liquid pump 34 input pipe 33, and then is pumped out along the liquid pump 34 output pipe again, thereby realizing the recycling of the cooling oil and reducing the processing cost.

[0034] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
