Problems solved by technology

[0005] The present invention provides a method for finishing the surface of a water pump impeller, which aims to solve the following problems in the prior art: (1) It is difficult to manually finish the inside of the blade, resulting in differences in the uniformity of finishing inside and outside the surface of the blade , which affects the working efficiency of the pump in the later stage; (2) The impeller of the pump is prone to slight displacement during the manual finishing process, resulting in a decrease in machining accuracy

Abstract

The invention belongs to the technical field of water pump manufacturing, and particularly relates to a water pump impeller surface finish machining method. The method includes the following steps offirstly, immersing a cast water pump impeller in grinding liquid, placing the water pump impeller onto a machine tool so that the circumferential surfaces of a front cover and a rear cover of the water pump impeller can be ground; secondly, grinding blades of the ground water pump impeller; and thirdly, clamping the ground water pump impeller on a water pump impeller surface fine machining deviceso that the blades of the water pump impeller can be polished. By means of the water pump impeller surface fine machining device in the third step, the blades are polished, the blade surface machiningprecision uniformity is improved, the stability of the water pump impeller in the machining process is improved, and machining precision is further improved.

Description

technical field [0001] The invention belongs to the technical field of water pump manufacturing, and in particular relates to a method for finishing the surface of a water pump impeller. Background technique [0002] The impeller is the core component of the water pump. The blades on the impeller of the water pump play a major role. The shape and size of the impeller of the water pump are closely related to the performance of the water pump. Since the water pump impeller is in direct contact with water during the working process, in order to reduce the friction loss of the water flow and improve the operation efficiency of the water pump, the surface of the water pump impeller needs to be finished after the manufacture of the water pump impeller. [0003] The surface of the traditional water pump impeller is finished by manual polishing. Since the water pump impeller is generally made of cast iron, and adopts the structure of a closed impeller, that is, it is composed of fr...
