[0002] Axial flow pumps are pumps that transport liquid along the axis by the force exerted by the blades of the rotating impeller on the liquid. There are several types: vertical, horizontal, oblique and cross-flow. The impeller of the axial flow pump is equipped with 2 to 7 blades and rotates in a cylindrical pump casing. The pump casing above the impeller is equipped with fixed guide vanes to eliminate the rotational motion of the liquid and convert it into axial motion, and convert the kinetic energy of the rotational motion into pressure energy. Axial flow pumps are usually single-stage, and a few are made into two-stage, with a wide flow range;

After placing the axial flow pump impeller on the top of the processing table, the clamping component will squeeze and fix it by extending, thereby improving the convenience of the axial flow pump impeller during turning processing;

[0022] S2: When the synchronous plate moves, the clamping plate is pushed by the spring to squeeze and fix the axial flow pump impeller, which improves the convenience of fixing the axial flow pump impeller and avoids the need for operators to make repeated adjustments. When the clamping plate squeezes the axial flow pump impeller, it pushes the moving rod to slide inside the synchronous plate;

[0023] S3: The end of the arc plate will move toward the surface of the moving rod, and during the movement, the telescopic plate will be pulled toward the surface of the synchronous plate through the elastic frame. During the movement, the telescopic plate will push the stabilizing block to squeeze and fix the axial flow pump impeller, thereby improving the stability of the axial flow pump impeller during turning.

[0024] S4: When the telescopic plate moves toward the surface of the synchronous plate, it drives the vertical plate to move through the fixed rod. When the vertical plate moves, it drives the circular hole plate to squeeze the waste inside the storage tank. Through squeezing, the coolant in the waste chips can quickly enter the water tank through the leakage hole for recycling.

[0025] The present invention has the following beneficial effects:

[0026] After the axial flow pump impeller is placed on the top of the processing table, the clamping component is started to move toward the center of the processing table, and the axial flow pump impeller is clamped and fixed by the clamping component. After the axial flow pump impeller is placed on the top of the processing table, the clamping component will squeeze and fix it by extending, thereby improving the convenience of the axial flow pump impeller during turning. When the clamping component squeezes the axial flow pump impeller, it will push the stabilizing component to start contracting. The stabilizing component is used to squeeze and fix the end of the axial flow pump impeller, thereby improving the stability of the lathe when turning the axial flow pump impeller. When the lathe processes the outer spherical surface of the axial flow pump impeller, the nozzle sprays the coolant in the water tank on the surface of the axial flow pump impeller for cooling treatment. The coolant will fall into the storage tank together with the waste generated by cutting for filtration. The circulation component will squeeze the waste generated by cutting, so that the coolant can quickly enter the water tank through the leak hole for recycling.

[0027] After the axial flow pump impeller is placed on the top of the processing table, the hydraulic rod is started to push the linkage ring to move toward the center of the processing table. When the linkage ring moves, it pushes the synchronous plate to move through the round rod. When the synchronous plate moves, it pushes the clamping plate through the spring to squeeze and fix the axial flow pump impeller, thereby improving the convenience of fixing the axial flow pump impeller and avoiding the need for operators to repeatedly adjust it.

[0028] When the clamping plate of the present invention squeezes the axial flow pump impeller, it will push the moving rod to slide inside the synchronous plate. When the moving rod moves, it pushes the arc plate to move through the center rod. The end of the arc plate will move toward the surface of the moving rod. When moving, the telescopic plate is pulled toward the surface of the synchronous plate through the elastic frame. When moving, the telescopic plate pushes the stabilizing block to squeeze and fix the axial flow pump impeller, thereby improving the stability of the axial flow pump impeller during turning. When moving, the telescopic plate slides inside the synchronous plate through the sliding rod, thereby improving the stability of the telescopic plate when moving. When moving, the clamping plate will push the telescopic plate to shrink synchronously through the telescopic rod, so that the stabilizing block can cooperate with the clamping plate to clamp and fix the axial flow pump impeller.

[0029] When the telescopic plate of the present invention moves toward the surface of the synchronous plate, it drives the vertical plate to move through the fixed rod. When moving, the vertical plate drives the circular hole plate to squeeze the waste inside the storage tank. Through the squeezing, the coolant in the waste can quickly enter the water tank through the leakage hole for recycling. When moving, the circular hole plate pushes the semicircular spring frame to deform through the right-angle plate. The semicircular spring frame pushes the triangular extrusion plate downward through the connection with the positioning plate through the connecting rod. The triangular extrusion plate is used to squeeze the waste downward, thereby further improving the circulation efficiency of the coolant.

[0057] A method for using a device for machining an outer spherical surface of an axial flow pump impeller comprises the following steps:

[0058] S1: After placing the axial flow pump impeller on the top of the processing table 8, start the clamping component 11 to move toward the center of the processing table 8, and use the clamping component 11 to clamp and fix the axial flow pump impeller.

During the movement, the telescopic plate 33 pushes the stabilizing block 36 to squeeze and fix the axial flow pump impeller, thereby improving the stability of the axial flow pump impeller during turning.

[0061] S4: When the telescopic plate 33 moves toward the surface of the synchronous plate 24, it drives the vertical plate 44 to move through the fixed rod 40. When the vertical plate 44 moves, it drives the circular hole plate 41 to squeeze the waste inside the storage tank 9. Through squeezing, the coolant in the waste can quickly pass through the leakage hole 10 into the water tank 5 for recycling.

[0062] When in use, after placing the axial flow pump impeller on the top of the processing table 8, start the clamping component 11 to move toward the center of the processing table 8, and use the clamping component 11 to clamp and fix the axial flow pump impeller.

The stabilizing component 12 is used to squeeze and fix the end of the axial flow pump impeller, thereby improving the stability of the lathe 1 when turning the axial flow pump impeller. When the lathe 1 processes the outer spherical surface of the axial flow pump impeller, the nozzle 7 sprays the coolant inside the water tank 5. The surface of the axial flow pump impeller is cooled, and the coolant will fall into the storage tank 9 together with the waste generated by cutting for filtration.

The clamping plate When the movable rod 23 squeezes the axial flow pump impeller, it will push the moving rod 22 to slide inside the synchronous plate 24. When the movable rod 22 moves, it pushes the arc plate 30 to move through the center rod 31. The end of the arc plate 30 will move toward the surface of the movable rod 22. When moving, the elastic frame 32 pulls the telescopic plate 33 to move toward the surface of the synchronous plate 24. When the telescopic plate 33 moves, it pushes the stabilizing block 36 to squeeze and fix the axial flow pump impeller, thereby improving the stability of the axial flow pump impeller during turning. When the telescopic plate 33 moves, it slides inside the synchronous plate 24 through the sliding rod 37, thereby improving the stability of the telescopic plate 33 when moving. When the clamping plate 23 moves, it will push the telescopic plate 33 to shrink synchronously through the telescopic rod 34. So that the stabilizing block 36 can cooperate with the clamping plate 23 to clamp and fix the axial flow pump impeller, when the telescopic plate 33 moves toward the surface of the synchronous plate 24, it will drive the vertical plate 44 to move through the fixing rod 40, and the vertical plate 44 will drive the circular hole plate 41 to squeeze the waste inside the storage tank 9 when moving, so that the coolant in the waste can quickly pass through the leakage hole 10 into the water tank 5 for recycling. When moving, the circular hole plate 41 pushes the semicircular spring frame 42 to deform through the right-angle plate 43, and the semicircular spring frame 42 pushes the triangular extrusion plate 45 to move downward through the connection between the connecting rod 46 and the positioning plate 47, and uses the triangular extrusion plate 45 to squeeze the waste downward, thereby further improving the circulation efficiency of the coolant.
