Abstract

The invention discloses a device and method for processing elongated holes with high cleanliness and low roughness. The device comprises a piston (1), an abrasive pressure cylinder (2), a feed inlet (3), a pressure bench (4), a top die (5), a bottom die (6), a workbench (7), a return inlet (8), a feed box (9) and a power device, wherein grooves matched with the shapes of parts are respectively arranged in the top die and the bottom die, happen to cover the parts after being combined and can clamp n-numbered parts each time; the grooves are connected end to end and are aligned on the same circumference; and the media flow in from the top die and flow out from the bottom die under the action of pressure. The method is characterized by utilizing the liquid flow media to polish the elongated holes with high cleanliness and low roughness under the action of a hydraulic machine. The processing parameters are as follows: the initial working temperature is not lower than 50 DEG C, the number of strokes is 4-5, the rated working pressure of the machine tool is 2.5MPa and the working pressure of the pressure bench is 100-200Kg. The invention can meet the processing requirements of the elongated holes for high cleanliness and low roughness, is simple, convenient and quick and suitable for batch processing and improves the production efficiency.

Description

technical field [0001] The invention belongs to mechanical ultra-precision processing technology, and relates to a processing method of elongated hole components. Background technique [0002] The smoothing of ordinary holes is done by using grinding rods and grinding paste. The advantages of this method are: the processing method is common, easy to operate, and low in cost, but its disadvantage is that it is difficult to effectively smooth the slender through holes and slender blind holes. . Due to the poor rigidity of the slender grinding mandrel, it is inevitable that there will be tool clearance during the processing process, the taper of the slender hole generatrix will increase, and there will be a large difference in the surface roughness of the parts, which cannot meet the required high cleanliness and low roughness requirements. Contents of the invention [0003] The purpose of the present invention is to design and provide a simple and quick ultra-precision mac...
