The opening of the material trough 105 is aligned horizontally. At this time, the third electric push rod 502 can drive the push plate 503 to move rightward and push the workpiece into the inside of the material trough 105 to complete the loading operation. At this time, the servo motor 108 is started and drives the half gear 109 to rotate, thereby driving the driven gear 107, the driving shaft 106 and the driving turntable 104 to rotate intermittently, so that the driving turntable 104 transports the material trough 105 loaded with the workpiece to one side of the limiting mechanism 8, and the sixth electric push rod 802 drives the fixed frame 803 to move to the front side opening of the material trough 105 and the upper end opening for limiting. After that, the tapping drill 606 is started, and the fifth electric push rod 603 drives the sliding sleeve 604, the connecting plate 605 and the tapping drill 60 6 moves downward, so that the tapping drill 606 performs a tapping operation on the workpiece. After the processing is completed, the drive turntable 104 rotates again to transport the processed workpiece to the clamping mechanism 3. At this time, the push rod 701 moves upward to push the processed workpiece out to the upper end of the material trough 105, and the mechanical gripper 305 is driven downward by the material-taking electric push rod 304, so that the mechanical gripper 305 grabs the workpiece, and the drive motor 307 is started to drive the moving screw 303 to rotate through the belt and two sets of pulleys 306, thereby driving the moving block 308, the material-taking electric push rod 304 and the mechanical gripper 305 to move above the conveyor 101, and the mechanical gripper 305 is driven downward by the material-taking electric push rod 304. The grabbed workpiece is placed on the upper end of the conveyor 101 for transportation. At the same time, the drive turntable 104 is rotated again, and the material trough 105 after discharging is rotated to the cleaning mechanism 4. At this time, the second electric push rod 403 drives the cleaning cover 404 to move downward and is sleeved on the outside of the material trough 105, so as to suck out the iron filings and residues inside the material trough 105 and clean them to the inside of the negative pressure box 407. When there are a lot of iron filings and residues outside the filter screen 411, the first electric push rod 402 is started and drives the scraper 410 to move downward, so as to scrape off the iron filings and residues outside the filter screen 411. As the drive turntable 104 rotates again, the material trough 105 after cleaning is driven to move to the feeding mechanism 5 again for feeding.
