Abstract
The invention relates to a mechanical processing method, and particularly relates to a method for grinding a concave surface with a concave-convex wheel; the method is characterized in that a tangent disk is firstly arranged on a grinding wheel, a horizontal guide rail is moved so that the tangent disk abuts against the concave surface of a convex wheel which is rotated so that a grinding point and the center of the tangent disk are kept on the same height, and then the changing curve of the height of the grinding point to the horizontal moving distance and the changing curve of the height of the grinding point to the corner of the convex wheel are obtained; the tangent disk is replaced by the grinding wheel, the interlinking relation between a vertical guide rail and the horizontal guide rail accords with the changing curve of the height of the grinding point to the horizontal moving distance, the interlinking relation between the vertical guide rail and the corner of the convex wheel accords with the changing curve of the height of the grinding point to the corner of the convex wheel, and then the concave surface of the convex wheel can be processed. The method is simple, convenient, scientific and reasonable and has high grinding precision.
Description
Technical field
The invention belongs to machining methods, specifically is a kind of method for grinding with concavo-convex concave surface of taking turns.
Background technology
Cam is widely used in all kinds of internal combustion engines, its accurate grinding is a difficult problem of machine tool industry always, main cause is the cam face complexity, when the abrasive grinding wheel vary in diameter, the grinding points Changing Pattern is difficult to grasp, the general very little but expensive CBN emery wheel of vary in diameter that adopts is processed, application number has proposed a kind of grinding processing method of cam for the patent application of " 200710067750.0 ", grinding position kept constant when grinding wheel diameter was changed, but when cam promotion roller moves, because technological requirement, cam face often is with concave surface, and this patented method does not fit into the grinding with concavo-convex concave surface of taking turns.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of scientific and reasonable, simple and convenient, method for grinding with concavo-convex concave surface of taking turns that precision is high is provided.
Technical scheme of the present invention is as follows:
A kind of method for grinding with concavo-convex concave surface of taking turns, the emery wheel that one diameter is not more than roller is contained on the vertical guide rail, vertical guide rail is contained on the horizontal guide rail, cam is contained on the rotating disk, the cam center of rotation is parallel with the emery wheel center, vertical guide rail, horizontal guide rail and cam rotating shaft three are linked by digital control system, it is characterized in that: the tangent disk that a diameter is not more than roller is set, tangent disk is contained on the emery wheel position, tangent disk cylindrical and cam concave surface points of tangency are grinding points, grinding points and tangent circle disk center are remained on the sustained height, tangent disk drives the concavo-convex concave surface of taking turns in lower edge at vertical guide rail and moves, in the moving process, the mobile and horizontal guide rail abuts against tangent disk on the cam concave surface, and rotating cam remains on the sustained height grinding points and tangent circle disk center; Note position and cam angle that vertical guide rail moves to each horizontal direction in when point,---moving horizontally variable in distance curve and grinding points height---the cam angle change curve that obtains the grinding points height, change tangent disk into emery wheel, make respectively that interaction relation meets the grinding points height between vertical guide rail and the horizontal guide rail---move horizontally the variable in distance curve, interlock meets point of contact height---cam angle change curve between vertical guide rail and the cam angle, can process the concave surface of cam.
The present invention is provided with a tangent disk earlier, the mobile and horizontal guide rail abuts against tangent disk on the cam concave surface, and rotating cam makes grinding points and cuts disk center and remain on the sustained height, draw the grinding points height--move horizontally the variable in distance curve, grinding points height---cam angle change curve, change tangent disk into emery wheel, make respectively that interaction relation meets the grinding points height between vertical guide rail and the horizontal guide rail---move horizontally the variable in distance curve, interlock meets grinding points height---cam angle change curve between vertical guide rail and the cam angle, can process the concave surface of cam.The present invention is simple and convenient, and is scientific and reasonable, the grinding accuracy height.
