Abstract
The invention relates to a method for machining workpiece circular arc radian, in particular to a grinding method for machining a large circular arc by the adoption of a molding grinder. The external diametral plane large arc grinding method comprises the steps that 1, firstly, a curved face grinding wheel is made, and modification is performed on the grinding wheel by the use of a grinding wheel dressing pen; the grinding wheel dressing pen and a center line of the grinding wheel form a certain angle; the angle is adapted to the large circular arc radian of a workpiece external diametral plane; 2, the grinding wheel is rotated, the dressing pen is kept still, and the grinding wheel is dressed into an inward concave curved face grinding wheel; an outer ring of a bearing is horizontally placed, and the center of the bearing is in the same horizontal line with the center of the curved face grinding wheel; the curved face grinding wheel is rotated, the workpiece is pushed forward to a target position, and then the workpiece is rotated. The external diametral plane large arc grinding method aims at solving the technical problem of achieving one-time molding large circular arc of the outer ring of the bearing on the molding grinder by the adoption of the curved face grinding wheel.
Description
Technical field
The present invention relates to a kind of method of processing work circular arc degree, be related specifically to a kind of method for grinding adopting form grinder to process orthodrome.
The invention still further relates to a kind of method of processing curve emery wheel.
The invention still further relates to a kind of curved surface emery wheel.
Background technology
In prior art, the great circle radian of processing roller outer ring is all adopt centerless grinder, and namely run through mill, this grinding machine automaticity is higher, but whole equipment price is higher, and will again arrange for different outer rings wheel profile.Shaping mill is generally not used in the great circle radian of processing outer ring, is mainly used in the step of machining bearing, but as the one of grinding machine, shaping mill is in processing, and have he self advantage, that is exactly simple and clear, and an object is clear; But in prior art, the surface due to emery wheel is one flat, and people it is generally acknowledged, the orthodrome of having no idea for processing outer ring; Here to explain, polishing where be actually; For bearing, need the place of polishing a lot, there are both ends of the surface in You Nei road, is exactly the surface of outer ring certainly in addition, and the orthodrome that this patent is said, just refers to the surperficial radian of outer ring.
Summary of the invention
Technology to be solved by this invention is: on shaping mill, adopt curved surface emery wheel to realize the orthodrome of disposal molding bearing outer ring.
1, for completing foregoing invention object, the present invention is achieved in that a kind of outer diameter face orthodrome method for grinding, it is characterized in that comprising the following steps:
(1) first curved surface emery wheel is made;
Utilize grinding wheel dressing pen, emery wheel is modified; The center line of grinding wheel dressing pen and emery wheel is had a certain degree; The great circle radian of this angle and workpiece outer diameter face should be fitted;
Rotate emery wheel, finishing pen keeps motionless, emery wheel is accomplished the curved surface emery wheel of indent;
By bearing outer ring horizontal positioned, the center of its center and curved surface emery wheel in the same horizontal line; Rotate curved surface emery wheel, workpiece is pushed ahead, be advanced to target location and stop, rotating.
Described sand finishing pen and emery wheel contact surface have radian.In second step, driving wheel made by curved surface emery wheel, rubs with outer ring, and the fixed mechanism of outer ring is along with friction is around center rotation.
The method that this patent adopts first uses grinding wheel dressing pen, by the polishing edge of emery wheel, be polished into the reverse radian of the maximum arc of bearing outer ring, certainly before grinding wheel, will arc maximum to outer ring time row calculate, in general, adding man-hour, client can directly provide, and calculates the angle of grinding wheel dressing pen according to radian; The maximum arc of curved surface emery wheel and the cylindrical finally completed is matched.At this moment fix outer ring, regulate center height, make its and curved surface emery wheel in the same horizontal line, at this moment advance curved surface emery wheel, allow the exterior surface of curved surface emery wheel and outer ring, while curved surface emery wheel as driving wheel, drive outer ring rotation.Thus polish the radian meeting initial design.
Second goal of the invention of the present invention is, provides a kind of method making the maximum arc surface emery wheel of polishing bearing outer ring.
Make a method for the maximum arc surface emery wheel of polishing bearing outer ring, it is characterized in that: fast pulley wheel finishing pen, dressing track is straight line, the linear angle of its movement locus and emery wheel axle center; Advance emery wheel, with grinding wheel dressing pen with contact, repair.The radian R of described corner dimension and outer ring forms complementation.When making bent sand, it should be noted that the setting of angle, because the emery wheel adopted buffed surface originally is different.But no matter how, ensure that the radian of revised curved surface and outer ring coincide always.
3rd problem of solution of the present invention is to provide a kind of curved surface emery wheel for bearing outer ring of polishing.
For completing foregoing invention object, the present invention is achieved in that a kind of curved surface emery wheel for bearing outer ring of polishing, and it is characterized in that: the grinding of described curved surface emery wheel is inner concave, and described inner concave and bearing outer ring radian match.
Accompanying drawing explanation
Fig. 1 is the grinding schematic diagram of this patent.
Fig. 2 is the schematic diagram making curved surface emery wheel.
Detailed description of the invention
In order to further description feature of the present invention, be further described below in conjunction with accompanying drawing:
As shown in Figure 2, first make curved surface emery wheel, fast pulley wheel finishing pen, dressing track is straight line, the linear angle of its movement locus and emery wheel axle center; Advance emery wheel, with grinding wheel dressing pen with contact, repair.The radian R of described corner dimension and outer ring forms complementation.When making bent sand, it should be noted that the setting of angle, because the emery wheel adopted buffed surface originally is different.But no matter how, ensure that the radian of revised curved surface and outer ring coincide always.
As shown in Figure 1, by bearing outer ring horizontal positioned, the center of its center and curved surface emery wheel in the same horizontal line; Rotate curved surface emery wheel, workpiece is pushed ahead, be advanced to target location and stop, rotating.
The method that this patent adopts first uses grinding wheel dressing pen, by the polishing edge of emery wheel, be polished into the reverse radian of the maximum arc of bearing outer ring, certainly before grinding wheel, will arc maximum to outer ring time row calculate, in general, adding man-hour, client can directly provide, and calculates the angle of grinding wheel dressing pen according to radian; The maximum arc of curved surface emery wheel and the cylindrical finally completed is matched.At this moment fix outer ring, regulate center height, make its and curved surface emery wheel in the same horizontal line, at this moment advance curved surface emery wheel, allow the exterior surface of curved surface emery wheel and outer ring, while curved surface emery wheel as driving wheel, drive outer ring rotation.Thus polish the radian meeting initial design.
In this manufacturing process upper, it is important to note that the making of curved surface emery wheel, a dirt of grinding wheel dressing pen should be the half of symmetrical radian.And radian should be consistent with the radian size of outer ring.
