Abstract

The invention relates to a method for abrading cam axle, wherein the invention is characterized in that: mounting one annular steel band on one active wheel and one tension wheel, to tension the annular steel band; the steel band has one outer surface adhered with abrasive sands, while its length is longer than annular steel band; one end of sand band is contacted to the steel band, while another end is tensioned by another tension wheel; the work-piece cam axle is contacted at one side of steel band, and another side has one support wheel supports the annular steel band and annular sand band, therefore, the annular sand band will not deform in abrasion; the central line of cam axle is parallel with the central axles of active wheel and tension wheel; the rotation angle of cam axle and its distance between its center position and abrasive plane can be controlled to meet the angle-strike curvature. The invention has simple operation and high accuracy.

Description

A kind of method for grinding of camshaft
Technical field
The invention belongs to field of mechanical manufacture technology, specifically is a kind of method for grinding of camshaft.
Background technology
The general emery wheel that adopts of existing cam processing carries out grinding, emery wheel centre of gyration line and the cam centre of gyration line parallel during grinding, rely on the distance of regulating between the two to process cam profile, because the continuous wearing and tearing of emery wheel, grinding wheel diameter is changed, and different grinding wheel diameters is different with the cam contour that two same center line Changing Patterns generate.In reality processing,, can only pass through expensive numerically-controlled cam grinder during the machining high-precision cam, and want timely revision program just can produce the high accuracy cam because cam contour changes, economical and practical inadequately.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of method for grinding that adopts simple and convenient, satisfactory for result, the camshaft that precision is high of abrasive band processing is provided.
Technical scheme of the present invention is as follows:
A kind of method for grinding of camshaft, it is characterized in that: a ring steel belt is contained on a driving wheel and the regulating wheel, make the ring steel belt tensioning, ring steel belt has an outer surface to adhere to the endless abrasive belt of grinding sand grains outward, length is greater than ring steel belt, one with endless abrasive belt abuts against on the ring steel belt, the other end by another regulating wheel with the endless abrasive belt tensioning, the workpiece camshaft abuts against a side of ring steel belt, on the opposite side relevant position, there is a support wheel that ring steel belt and endless abrasive belt are withstood, endless abrasive belt unlikely generation when being subjected to grinding force is out of shape, camshaft center line and driving wheel, the central axis of regulating wheel is parallel, and the corner-lifting curve that meets cam by the distance between the grinding plane in the control anglec of rotation of camshaft and center and abrasive band gets final product grinding and go out the camshaft profile.
When rotating, driving wheel of the present invention drives the ring steel belt motion, there is enough frictional force to make driving wheel drive the ring steel belt motion between ring steel belt and the driving wheel making under the regulating wheel effect, also there is enough frictional force to make the motion of steel strip driving abrasive band between endless abrasive belt and the ring steel belt, the sand grains of the abrasive band outer surface of motion is in order to grinding raised wheel shaft outer surface, simultaneously because the supporting role of support wheel is indeformable when making the endless abrasive belt grinding, corner-lifting curve that the distance between the anglec of rotation of control camshaft and the grinding plane in center and abrasive band meets camshaft gets final product grinding and go out cam contour.The present invention is simple and convenient, is convenient to operation, the machining accuracy height.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, a kind of method for grinding of camshaft, it is characterized in that: a ring steel belt 1 is contained on a driving wheel 2 and first regulating wheel 3, make ring steel belt 1 tensioning, outside ring steel belt 1, there is an outer surface to adhere to the endless abrasive belt 4 of grinding sand grains, length is greater than ring steel belt 1, one of endless abrasive belt 4 near ring steel belt 1, the other end by second regulating wheel 5 with endless abrasive belt 4 tensionings, workpiece camshaft 6 abuts against a side of ring steel belt 1, there is a support wheel 7 that ring steel belt 1 and endless abrasive belt 4 are withstood at opposite side, endless abrasive belt 4 unlikely generation when being subjected to grinding force is out of shape, camshaft 6 center lines and driving wheel 2, first regulating wheel 3, the central axis of second regulating wheel 5 is parallel, and the corner-lifting curve that meets cam by the distance between the grinding plane in the control anglec of rotation of camshaft 6 and center and abrasive band 4 gets final product grinding and go out the camshaft profile.
The width of endless abrasive belt 4 of the present invention is greater than the width of camshaft 6, and the width of ring steel belt 1 is beneficial to finishing of grinding greater than the width of endless abrasive belt 4.
Support wheel 7 of the present invention can have a plurality of as required, is as the criterion ring steel belt 1 and endless abrasive belt 4 can be withstood.
