Abstract
The invention provides a method of finishing the compound machining wheel of the outer end ring of a micro-flange. The method adopts the theory of numerical control. Three numerical control shafts driven by a servo-actuator makes a planker move and a grinding wheel rotate under the control of a numerical control grinding machine. Eight linkage methods including oblique line finishing, surpassing grinding wheel, diamond pen rotating and free-wheeling straight line and so on are completed by the diamond pen with single point that is driven by the planker and a diamond pen frame to make the sharpness of a grinding wheel taper angel and the free adjustment of the starting angle of the oblique line and the included angle of a formed grinding wheel realized. The finishing method of the invention leads the finished grinding wheel to high precision. The vertical difference of a guard side and an outside diameter less than 1 Mu m and a knuckle R<SUB>max</SUB> is 0.2mm and the shape of the guard side always is concave. The starting angle of the oblique line Alpha and the included angle of the formed grinding wheel Beta can be easy to be adjusted. The finishing method has high efficiency.
Description
Technical field:
The invention belongs to the form truing technical field, relate generally to a kind of method for trimming of minitype flange external ring bearing edge guard composite abrasive grinding wheel.
Background technology:
The flanged outer ring deep groove ball bearing has a wide range of applications at precision instrument, instrument industry.Flanged outer ring as shown in Figure 1, because of its precision height, difficulty of processing are big, is the difficult point of grinding process always.As the bearing outside diameter and the rib of reference for installation, two kinds of method grindings of main at present employing: a kind of is external diameter and rib grinding respectively, and another kind is rib and external diameter composite grinding.The former crushing is simple, as shown in Figure 2, it adopts single-point diamond pen trimming wheel external diameter and end face respectively based on the turning ratio juris, in occupation of dominant position, this method trimming wheel and grinding efficiency are too low in the bearing grinding of existing flanged outer ring for the method for this trimming wheel; The latter then is comparatively advanced method for grinding, and with the shape that crushing becomes to stipulate, a clamping can be finished the grinding of external diameter and rib, grinding efficiency height simultaneously.But, there is different problems in the method for trimming of this formed grinding wheel, the main method of taking at present has two kinds: (1) adopts two straight line trimmers to repair two faces of formed grinding wheel respectively, as shown in Figure 3, the deficiency that this method exists is: the finishing angle adjustment trouble of benchmark trimmer setting angle, two trimmers, the complicated in mechanical structure of trimmer, to take the lathe space big, and dressing accuracy is lower; (2) based on the numerical control interpolation principle, finish by the single-point diamond pen, repair track as shown in Figure 4, the deficiency that this method exists is: the emery wheel wedge angle is not sharp, and knuckle is overproof after the grinding.
Summary of the invention:
To be produced the emery wheel wedge angle not sharp in order to solve the trimming wheel external diameter finished based on the numerical control interpolation principle by the single-point diamond pen and end face, the overproof problem of knuckle after the grinding, the method for trimming that the purpose of this invention is to provide a kind of minitype flange external ring bearing edge guard composite abrasive grinding wheel, it is based on the numerical control principle, control the motion track of single-point diamond pen by the interlock mode of control numerical control axle, a kind of method for trimming of composite abrasive grinding wheel is provided, it is sharp to have wedge angle after emery wheel is shaped, grinding minitype flange external ring bearing edge guard precision height, the knuckle standard, a clamping can be finished the grinding of external diameter and rib simultaneously.
In order to realize the foregoing invention purpose, the present invention has adopted following technical scheme:
The method for trimming of described minitype flange external ring bearing edge guard composite abrasive grinding wheel, it is based on the numerical control principle, by the control of Programmable Logic Controller or computer to three numerical control axles of numerically control grinder X-axis, W axle and A axle, make its X-axis driven by servomotor vertically repair planker feeding, W axle driven by servomotor and laterally repair planker feeding, the rotation of A axle driven by servomotor Buddha's warrior attendant penholder, above-mentioned three numerical control axles drive the single-point diamond pen and realize with crushing being shapes such as straight line, oblique line and circular arc under the control of setting program.
The method for trimming of described minitype flange external ring bearing edge guard composite abrasive grinding wheel, after the parameter of its trimming wheel is set, three numerical control axles of Digit Control Machine Tool link under setting program, and the mutual interlock method between them is: the X-axis feeding realizes O → A finishing idle running straightway, and W axle, A axle are motionless; X-axis, the interlock of W axle realize A → B → C finishing oblique line section, and the A axle is motionless; A axle rotation realizes arc section C → D diamond pen finishing angular transformation, and X-axis, W axle are motionless; The W axle moves realizes D → E finishing idle running straightway, and X-axis, A axle are motionless; X-axis, the interlock of W axle realize E → B → F finishing oblique line section, and the A axle is motionless; The X-axis feeding realizes F → G finishing idle running straightway, and W axle, A axle are motionless; The W axle moves realizes that G → H returns the idle running straightway, and X-axis, A axle are motionless; The rotation of A axle realizes arc section H → O diamond pen finishing angular transformation, X-axis, W axle are motionless, these eight kinds of method for trimming can be recycled, under three numerical control axle interlocks, finish the whole finishing circulation of emery wheel by the single-point diamond pen, finish the finishing oblique line, surmount emery wheel, diamond pen rotation, idle running straight line, method such as finishing oblique line, the shape that crushing is become to stipulate.
Owing to adopted technical scheme as mentioned above, the present invention has following good effect:
1, the dressing accuracy height of formed grinding wheel: the vertical difference of rib and external diameter is less than 1 μ m, and the rib shape is only recessed not protruding.
2, the wedge angle B of formed grinding wheel is extremely sharp: the knuckle R between rib and the external diameter
MaxBe 0.2mm.
3, initial oblique line angle [alpha] and formed grinding wheel angle β are easy to adjust: this angle can directly be set by program.
4, dressing efficiency is higher: under digital control system control, three numerical control axles are moved and the grinding wheel arc dresser rotation by the driven by servomotor planker, and efficient is higher.
