Arc gear pump pump body Detailed

Circular gear pump pump Detailed explanation of a small pump: processing arc gear pump 8 holes when the pump should be punched on the reference plane, in order to fine grinding time to determine that side of grinding. The following began to process the other side 1. First of all we should do a good job arc gear pump body mold correctly placed on the machine, have a chance to explain the processing mold method. 2. After the mold is installed, put the pump body datum on it, pay attention to the no-foreign matter between the surface and the surface when it is on live, otherwise it may be scrapped. 3. After the good, the pressure is good, do not straighten points, because straightening the mold has been found in the sub-oh, when the mold attention. 4. The first knife, usually disc cutter, or cow nose knife. 5 on the knife, enter the machine tool 6 on the knife, edit the program, pay attention to the coordinate system and the knife point. 7. When it is correct, start the program. Pay attention to observe 8. Plane processing, pay attention to stay about 0.05mm, is to keep when grinding. 9. Continue to process the gear hole, hole diameter 60MM big, with a diameter of 50 knife can, cast iron pump body, with a rough boring cutter diameter boring can, because my company casting products are rules, after Seiko casting, product processing faster, reliable quality. 10. Rough finishing hole, with fine boring tool, fine boring bore, to ensure that the center distance plus or minus 0.08MM, the hole size can not exceed the decrease 0.05MM. 11 on the positioning knife, positioning. 12. On the drill, drilling. 13. Taps, clasps. 14. Lift the knife, back to zero, the processing is completed successfully. Pay attention to the editing program must be careful, start the program is more careful, the knife should be right, the last knife when processing the surface, to maintain a smooth surface, the mold must be pulled straight, points good. Arc gear pump internal gear machining process profile 1. Rough car shape on the lathe 2. Fine car gear shape on the lathe 3. The car is sent to the inspection department, inspection qualified, served gear hobbing workshop 4. Upon receipt, Rough milling teeth 5. Fine milling teeth 6. Serve the inspection department after the inspection 7. Serve the hard department, 昝 fire 8. Gear completed successfully
