First, when a cylindrical workpiece 5 is cut and processed, the second drive motor 35 is started, and the output end of the second drive motor 35 drives the bidirectional threaded screw 38 to rotate, thereby driving the first traction block 39 and the second traction block 40 to move toward each other, thereby driving the first arc pressure plate 24 and the second arc pressure plate 25 to move toward the processed cylindrical workpiece 5. When the second drive motor 35 stops running, the first arc pressure plate 24 and the second arc pressure plate 25 are clamped in the cylindrical workpiece 5. The outer wall of the workpiece 5 is moved to fix the columnar workpiece 5, and then the columnar workpiece 5 is released by the three-claw chuck 4, and then the hydraulic cylinder 44 is started, and the output end of the hydraulic cylinder 44 drives the L-shaped block 37 to drive the clamping seat 34 to move away from the three-claw chuck 4, so that the columnar workpiece 5 after cutting is moved out from the inner side of the three-claw chuck 4, and then the first drive motor 17 is started, and the output end of the first drive motor 17 drives a reciprocating screw 18 to rotate, thereby driving a slider 20 to drive the clamped columnar workpiece 5 to move away from one side of the three-claw chuck 4, thereby realizing the automatic unloading of the processed columnar workpiece 5; When a reciprocating screw 18 rotates, a second arc pressure plate 25 drives the first arc pressure plate 24 to rotate, thereby driving another second arc pressure plate 25 to drive another reciprocating screw 18 to rotate, thereby driving another slider 20 to drive the clamped columnar workpiece 5 to move toward the three-claw chuck 4, thereby realizing automatic loading while unloading the cut columnar workpiece 5, thereby reducing the time for manual replacement of unloading and loading by the staff, thereby improving the efficiency of cutting the columnar workpiece 5; When the moving seat 22 moves with one slider 20 in the direction away from the three-claw chuck 4, the other moving seat 22 moves with the other slider 20 in the direction of the three-claw chuck 4. After the two columnar workpieces 5 are staggered during movement, when one roller 26 moves from the second straight groove 13 to the second inclined groove 14, when the slider 20 continues to move, the slider 20 drops along the second inclined groove 14 to the first straight groove 9 under the action of the auxiliary spring 33.

When the roller 26 is separated from the second rotating baffle 12, the second rotating baffle 12 abuts against the inside of the first straight slot 9, so that the roller 26 that has rolled into the inside of the first straight slot 9 can move again and can be restored to the inside of the second straight slot 13 through the second rotating baffle 12. When the other roller 26 moves from the lowest point of the first inclined slot 10 to the highest point When the first rotating baffle 11 contacts the first rotating baffle 11 during the process, the first rotating baffle 11 is pushed to rotate toward the inside of the second straight groove 13. When the other roller 26 separates from the first rotating baffle 11, the first rotating baffle 11 abuts against the inside of the second straight groove 13, so that the other roller 26 can slide through the first inclined groove 10 to the inside of the first straight groove 9 again when resetting, thereby ensuring that the two rollers 26 will not enter the wrong channel during the movement, thereby improving the stability of the alternating operation of the columnar workpiece 5, thereby improving the overall practicality of the device; When the other moving seat 22 slides on the inner side of the first straight groove 9 through the roller 26, after the two columnar workpieces 5 are interlaced, the spur gear 29 on one side of the other moving seat 22 contacts the spur rack 21, and the spur gear 29 is driven by the spur rack 21 to drive the worm 28 to rotate, thereby driving the worm gear 30 to drive the third connecting seat 23 to rotate through the first rotating shaft 31. When the spur gear 29 is separated from the spur rack 21, the third connecting seat 23 rotates 180 degrees, so that the columnar workpiece 5 originally located at the bottom can be rotated to the top, so as to facilitate the stability of subsequent loading; When a new columnar workpiece 5 is loaded onto the inner side of the three-claw chuck 4 and clamped by the three-claw chuck 4, the second drive motor 35 starts to drive the bidirectional threaded screw 38 to rotate, thereby driving the first traction block 39 and the second traction block 40 to move away from each other. When one end of the second arc pressure plate 25 contacts the power wheel 36 in the process of moving away from the columnar workpiece 5, it rotates through the second rotating shaft 41 under the blocking action of the power wheel 36, thereby driving the torsion spring 42 to twist, so that the second arc pressure plate 25 stops moving and is in an inclined state, so that during the subsequent cutting process of the columnar workpiece 5, debris falling into the inner side of the second arc pressure plate 25 can slide away, thereby ensuring the cleanliness of the surface of the second arc pressure plate 25, so as to facilitate the stability of subsequent clamping.
