[0037] Working principle: The circular table 23 at the top of the fixed table 21 serves as a workpiece bearing surface. The dovetail groove 27 formed at the bottom of the clamping block 26 is in sliding fit with the dovetail tenon 25 on the two sides of the fixed block 24. During installation, the clamping block 26 is slid into the dovetail tenon 25 from front to back, so as to limit the left-right movement and the up-down movement of the clamping block 26, thereby preliminarily realizing the installation positioning of the clamping block 26. The positioning pin 212 is inserted into the counterbore 210 at the top of the clamping block 26 and the positioning hole 211 at the top of the circular table 23, so as to limit the front-back displacement of the clamping block 26. At this time, the clamping block 26 is limited and cannot move. When the workpiece is clamped, the mold workpiece to be processed is placed between the two clamping blocks 26 on the same circular table 23. By screwing the bolt two 28 on one side of the clamping block 26, the bolt two 28 drives the end portion of the gasket 29 to move towards the workpiece through the threaded action, so that the gasket 29 is tightly attached to the surface of the workpiece, thereby realizing the fixation of the workpiece. A plurality of fixed tables 21 and circular tables 23 constitute a multi-station machining platform. Each circular table 23 can independently complete the clamping and fixation of a group of workpieces. The operator can clamp workpieces on multiple stations at one time. Subsequently, continuous machining is realized through platform switching, without the need for frequent shutdown and part replacement, thereby greatly improving the batch processing efficiency. After the machining process starts, the spray head 38 at the bottom of the housing 37 sprays the cutting fluid into the contact area between the cutting spindle 911 and the workpiece. After completing the cooling and chip removal functions, the cutting fluid flows along the workpiece surface to the top of the support table 6. The cutting fluid flows into the cavity 7 inside the support table 6 through the through hole 32. The guide plate 31 guides the cutting fluid in the cavity 7 to the water tank 8 at the bottom of the inner side of the housing 1. The filter screen 34 fixed at the top of the inner wall of the flow pipe 33 filters the cutting fluid and intercepts the chips above the filter screen 34. The filtered cutting fluid is drawn by the water pump 35 and sprayed back into the machining area through the hose 36, housing 37 and spray head 38, forming a cycle of cutting fluid. Processing debris accumulates on the filter screen 34 inside the water tank 8. Motor 44 drives the transmission wheel 42 to rotate. Since the two transmission wheels 42 are connected by a transmission belt 43, the rear transmission wheel 42 drives the transmission belt 43 and the front transmission wheel 42 to rotate synchronously. The insert 47 fixed to the rear top of the outer wall of the transmission belt 43 moves along with the transmission belt 43. Because the insert 47 is inserted into the guide groove 46 of the moving block 45, it drives the moving block 45 to move synchronously. Through sliding engagement with the guide groove 46, the insert 47 drives the moving block 45 to reciprocate linearly along the limiting groove 411 on the inner wall of the protective cover 41. When the moving block 45 moves to the left, the scraper 48 will move simultaneously... The scraper moves along the bottom and inner wall of the water tank 8 to the left, pushing the debris accumulated on the filter screen 34 in the water tank 8 towards the chip removal channel 410 at the front end of the water tank 8. Since the blocking plate 49 at the front end of the water tank 8 is designed with an inclined surface, when the scraper 48 moves to the left and contacts the blocking plate 49, the scraper 48 generates an upward pushing force on the inclined surface, overcoming the gravity of the blocking plate 49 and lifting the blocking plate 49 upward, exposing the chip removal channel 410. The debris continuously pushed by the scraper 48 is discharged from the water tank 8 through the chip removal channel 410, thus cleaning the debris. When the moving block 45 returns to the right, the scraper 48 separates from the blocking plate 49, and the blocking plate 49 falls under its own gravity, resealing the chip removal channel 410.
