Abstract
The invention belongs to the field of mechanical manufacture methods, and relates to a cam shaft grinding method in particular. The cam shaft grinding method is characterized in that a fixed plate is mounted on a fixed pedestal; an annular abrasive belt for grinding sand grains is adhered on one side of the fixed plate, tightly close to the outer surface of the fixed plate; the annular abrasive belt is opened by a drive wheel and a tension wheel; the other end of the annular abrasive belt is tensioned by another tension wheel; a workpiece cam shaft is tightly close to the other side of the annular abrasive belt, corresponding to the position of the fixed plate; the central line of the cam shaft is parallel with the central axes of the drive wheel and the tension wheel; and the profile of the cam shaft can be grinded by controlling that the rotation angle of the cam shaft and the distance between the central position of the cam shaft and the grinding plane of the abrasive belt satisfy the corner-lift curve of a cam. The cam shaft grinding method is simple and convenient, is convenient to operate, and has high processing precision.
Description
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.The patent No. of my application discloses a kind of by ring steel belt drive endless abrasive belt for " 200610154707.3 " name is called " a kind of method for grinding of camshaft ", distance between the anglec of rotation of control camshaft and the grinding plane of center and endless abrasive belt meets the corner-lifting curve grinding cam contour of camshaft, but in actual manufacture process, the discovery ring steel belt makes trouble, and ring steel belt is easy inadequately with cooperating of endless abrasive belt.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of method for grinding of more simple and convenient, effect is better, precision is higher camshaft is provided.
Technical scheme of the present invention is as follows:
A kind of method for grinding of camshaft, it is characterized in that: fixed head is installed on the fixed pedestal, fixed head one side is adhered to the endless abrasive belt of grinding sand grains near outer surface, endless abrasive belt is opened by a driving wheel and regulating wheel, the endless abrasive belt other end by another regulating wheel with the endless abrasive belt tensioning, the workpiece camshaft abuts against the opposite side of endless abrasive belt and fixed head correspondence position, 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 endless abrasive belt motion, the sand grains of the endless abrasive belt outer surface of motion is in order to grinding raised wheel shaft outer surface, simultaneously because the supporting role of fixed head 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: fixed head 1 is installed on the fixed pedestal, fixed head 1 one sides are adhered to the endless abrasive belt 2 of grinding sand grains near outer surface, endless abrasive belt 2 is opened by a driving wheel 4 and first regulating wheel 3, endless abrasive belt 2 other ends by second regulating wheel 6 with endless abrasive belt 2 tensionings, workpiece camshaft 5 abuts against endless abrasive belt 2 and opposite side fixed head 1 correspondence position, camshaft 5 center lines and driving wheel 4, first regulating wheel 3, the central axis of second regulating wheel 6 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 5 and center and abrasive band gets final product grinding and go out the camshaft profile.
