Abstract
The invention discloses a manufacturing method for an eccentric shaft of a compressor core. The manufacturing method comprises the following steps: step 1, milling two end surfaces of an eccentric shaft blank, then turning a main journal (1) and an auxiliary journal (2) on the eccentric shaft and turning a crank (3) between the main journal (1) and the auxiliary journal (2) , wherein the length of the main journal (1) is longer than the length of the auxiliary journal (2); and step 2, drilling holes and milling flutes in a thrust surface I (4) and a thrust surface II (5) located at two sides of the crank (3), respectively drilling radial holes (6) in the main journal (1) and the auxiliary journal (2), deburring and cleaning the radial holes (6) and finally subjecting the main journal (1), the auxiliary journal (2), the crank (3), the thrust surface I (4) and the thrust surface II (5) to fine grinding.
Description
Technical field
The present invention relates to a kind of method for manufacturing accentric shaft of compressor movement.
Background technique
The eccentric shaft of present compressor movement exists morpheme when producing in enormous quantities in the process midium or long term of producing and requires phenomenon can only be reluctantly up to standard, show that mainly the major and minor axis cylindricity is overproof, the relative major axis of the minor axis overproof phenomenon of beating, consumption of compressor is very big like this, has influenced the utilization efficiency of compressor greatly.
Summary of the invention
The invention provides a kind of method for manufacturing accentric shaft of compressor movement, it not only can guarantee the roughness of minor axis end face, guarantees minor axis to the perpendicularity of major axis, and has guaranteed beating of the relative major axis of minor axis, thereby improved the machining accuracy of part, reduced the power consumption of compressor complete machine.
The present invention has adopted following technological scheme: a kind of method for manufacturing accentric shaft of compressor movement, it may further comprise the steps: step 1, the both ends of the surface of first-selected milling eccentric shaft blank, turning goes out main journal and countershaft neck on eccentric shaft then, the length of main journal is longer than the length of countershaft neck, and car goes out crank throw between main journal and countershaft neck; Step 2, thrust surface I and the boring of thrust surface II and groove milling in the crank throw both sides at main journal and countershaft neck difference drilling radial hole, again to the radial hole deburring, are cleaned then, finish grind main journal, countershaft neck, crank throw, thrust surface I and thrust surface II at last.
The method of described correct grinding main journal and countershaft neck is the infeed of centreless grinding, the guide wheel shaft axis of the infeed of centreless grinding milling machine when grinding and the shaft axis of grinding wheel are crossed as 30 °, this makes workpiece add the very little end thrust of formation in man-hour, the existence of this thrust makes eccentric shaft be close to the limiting stopper of countershaft neck end face, limiting stopper contacts with countershaft neck end face in course of working all the time, the roughness of limiting stopper and the countershaft neck end face that is in contact with it and the cylindricity that parallelism has guaranteed eccentric shaft effectively and beat.Clamp main journal during the end face of described step 1 turning countershaft neck earlier.
The present invention has following beneficial effect: after having adopted above technological scheme, the present invention can guarantee the roughness of minor axis end face, guarantee that minor axis is to the perpendicularity of major axis, also guaranteed simultaneously beating of the relative major axis of minor axis, simultaneously because the tool marks of turning are circular, this is consistent with the rotation that centerless grinding machine adds man-hour, naturally just improved the stationarity of centerless grinding, also just guaranteed the cylindricity of major and minor axis processing, the machining accuracy that has improved part has also just reduced the power consumption of compressor complete machine.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
In Fig. 1, the invention provides a kind of method for manufacturing accentric shaft of compressor movement, it may further comprise the steps: step 1, the both ends of the surface of first-selected milling eccentric shaft blank, turning goes out main journal 1 and countershaft neck 2 on eccentric shaft then, clamps main journal 1 during the end face of turning countershaft neck 2 earlier, is circular in the tool marks of turning, the length of main journal 1 is longer than the length of countershaft neck 2, and car goes out crank throw 3 between main journal 1 and countershaft neck 2; Step 2, thrust surface I 4 and 5 boring and the groove millings of thrust surface II in crank throw 3 both sides, then at main journal 1 and countershaft neck 2 difference drilling radial holes 6, again to radial hole 6 deburrings, clean, finish grind main journal 1 at last, countershaft neck 2, crank throw 3, thrust surface I 4 and thrust surface II 5, the method of described correct grinding main journal 1 and countershaft neck 2 is infeeds of centreless grinding, the guide wheel shaft axis of the infeed of centreless grinding milling machine when grinding and the shaft axis of grinding wheel are crossed as 30 °, this makes workpiece add the very little end thrust of formation in man-hour, the existence of this thrust makes eccentric shaft be close to the limiting stopper of countershaft neck 2 end faces, limiting stopper contacts with countershaft neck 2 end faces in course of working all the time, the roughness of limiting stopper and countershaft neck 2 end faces that are in contact with it and the cylindricity that parallelism has guaranteed eccentric shaft effectively and beat.
