Abstract

The present invention disclosed a processing method for the pump pump body of ship spraying. This method is to install the dedicated fixture based on the pump -based processing fixture on the three -axis vertical CNC processing center machine tool workbench.The screw is parked below the axis, and the end surface 41 of the pump 4 is matched with the specific inner ring with the clip.; Follow the sequentially milling pump 42, and all holes on the processing end surface 42.After the completion, the water spray pump pumping body 4 is installed, the flipping board is flipped up 180 ° up, so that the positioning screw is stopped above the rotor, and the end surface 42 of the pump 4 is on the Chole and D holes.The rhombus positioning is combined, and the flange of 42 end of the pump is 42nd ends at the pump body.The processing method of the present invention reduces the processing process and improves the size, position accuracy and production efficiency of the processing.

Description

technical field [0001] The invention relates to a method for processing a pump body, in particular to a method for processing a pump body of a ship water jet propulsion pump, and belongs to the technical field of mechanical processing. Background technique [0002] The ship water jet propulsion pump is the core component of a special ship propulsion device. Its working principle is to propel the ship to run through the reaction force of the water jetted by the water jet propulsion pump. Compared with the conventional propeller propulsion method, it has fast propulsion speed, high efficiency, strong anti-cavitation performance, low vibration and noise, excellent maneuverability, and is suitable for shallow water navigation, which is more and more sought after by the market. [0003] The water jet propulsion pump is a device for ship propulsion. On the end face of the pump body, positioning holes and installation holes for controlling the ship's forward and backward and other ...
