Grinding device and grinding method for processing spiral blades for pumps

Abstract

The invention relates to the technical field of machining. A grinding device for processing helical blades for pumps, comprising a case, a grinding assembly, a first rotating drive assembly, and a second rotating drive assembly; a neutral gear is provided in the middle of the top surface of the housing, and a slide rail is provided on the neutral gear; the middle part of the slide rail The neutral position of the slide rail is provided; the grinding assembly is matched with the slide rail; the first rotary drive assembly and the second rotary drive assembly are respectively arranged on the left and right sides of the chassis; the lower end of the first rotary drive assembly is arranged on the chassis, and the first rotary The upper end of the driving assembly is set on the slide rail; the parts are fixed between the first rotating driving assembly and the second rotating driving assembly, and the parts are ground into a spiral shape through the cooperation of the grinding assembly with the first rotating driving assembly and the second rotating driving assembly . The technical effect of the patent is that the cost of the device is low, the structure is ingenious, the operation is convenient and fast, the processing efficiency is high and the automatic processing of the spiral blade is realized.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a grinding device and a grinding method for processing spiral blades for pumps. Background technique [0002] In actual production, modern CNC grinding machine equipment has realized automatic spiral processing, such as a fully automatic complex spiral grinding machine disclosed in the Chinese utility model patent with the publication number CN207402227U and the announcement date of 2018.05.25, including the bed , a grinding head assembly equipped with a grinding wheel, a head frame assembly equipped with a workpiece fixture, a dresser assembly equipped with a dressing wheel, and a feeding assembly; the bottom of the grinding head assembly and the head frame assembly are respectively installed with mutually perpendicular X-axis servo drives Linear sliding unit 1 and Z-axis servo-driven linear sliding unit 2. Pneumatic linear sliding unit 3 parallel to the Z-axis is ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing grinding machines and the grinding machines have the following problems: (1) the cost of the current grinding machines is too high, and most of them are processed by semi-automatic grinding machines; The steps are too cumbersome, and the processing efficiency and economic benefits are low; (3) At present, the grinding process of the spiral line can be realized, but for the processing of the spiral parts, it is still manually polished slowly. The conventional grinding machine fixes the part, or fixes one end of the part but can only move in one direction, and cannot grind the part from multiple angles and directions, resulting in the inability to effectively process the spiral blade, and there is no automatic grinding machine on the market. Machining of spiral blades

[0004] To sum up, the above-mentioned grinding machines have the problems of high cost, cumbersome processing, low processing efficiency and inability to automatically process spiral parts
