[0029] Specifically, when this bench lathe is in use: First, adjust the spacing of the load according to the size of the workpiece. Rotate the first handwheel 5026 to drive the bidirectional screw 5025 to rotate. The rotation of the bidirectional screw 5025 causes the two connecting plates 5027 to move inward or outward simultaneously, thereby moving the two load-bearing frames 5029, and thus adjusting the spacing between the two load-bearing columns 5030. The first motor 5018 drives the first screw 5016 to rotate. The rotation of the first screw 5016 causes the adjusting seat 5015 to move. The movement of the adjusting seat 5015 drives the connecting rod 5014 and the mounting frame 501 to move, thereby driving the entire stability-enhancing and load-bearing mechanism 5 to move axially along the first screw 5016. Move to a suitable position, then place the workpiece between the two load-bearing columns 5030, and insert the inner end of the workpiece into the first chuck 4. Then, clamp and fix the workpiece through the first chuck 4. Then, the second motor 5021 drives the second screw 5020. The rotation of the second screw 5020 causes the lifting plate 5022 and the connecting column 5023 to descend, thereby causing the load-bearing column 5030 to descend. Then, the telescopic cylinder 507 drives the lifting column 503 to drive the inclined block 5012 to move. At the same time, the first stability-enhancing wheel 504 rises to contact the bottom of the workpiece. The movement of the inclined block 5012 causes the transmission wheel 5011 to move. The movement of the transmission wheel 5011 drives the clamping frame 509 to rotate, thereby causing the second stability-enhancing wheel 5010 to rotate, so that the second stability-enhancing wheel 5010 contacts the surface of the workpiece. Then, the fifth motor 29 drives the fifth screw 28 to rotate, causing the first sliding seat 30 to move along the fifth screw 28, driving the moving plate 6 to slide on the bed frame 1, realizing the position adjustment of the tool rest 12 and the turning tool 13 in the horizontal direction. Rotate the second handwheel 25 to drive the fourth screw 24 to rotate, causing the pushing block 26 to move along the fourth screw 24, and then driving the connecting plate 11 and the tool rest 12 to move, realizing the feed movement of the turning tool 13. The operation is simple, and the position of the turning tool 13 can be accurately adjusted according to the processing requirements. The fourth motor 19 drives the driving pulley 20 to rotate. The driving pulley 20 drives the transmission shaft 3 to rotate through the belt 21, thereby causing the first chuck 4 to rotate, realizing the rotational movement of the workpiece, and realizing the machining of the workpiece. After the machining is completed, the third motor 805 drives the third screw 804 to rotate, causing the adjusting block 806 to move along the third screw 804, driving the adjusting rod 807 to move, and then realizing the flipping of the mounting plate 7 around the rotation connection point of the vertical plate 801 and the assembly block 802, so as to be able to dump the waste chips accumulated on the mounting plate 7.
