The specific embodiment
Below in conjunction with accompanying drawing the technology of the present invention content is explained:
Be illustrated in figure 1 as a typical pivoting support, mainly comprise outer ring 1, inner ring 2 and steel ball 3.Wherein outer ring 1 provides the raceway of steel ball 3 motions to include interior raceway Up Highway UHW 10, and oil groove A11, interior raceway Down Highway 12, inner ring 2 provide the raceway of steel ball 3 motions to include outer raceway Up Highway UHW 20, oil groove B21, outer raceway Down Highway 22.Basic conception according to 4 contacts, point A, B, C, D are respectively the center of circle of interior raceway Up Highway UHW 10, interior raceway Down Highway 12, outer raceway Down Highway 22 and outer raceway Up Highway UHW 20, and E, F, G, H are respectively the contact point of steel ball bus 30 and interior raceway Up Highway UHW 10, interior raceway Down Highway 12, outer raceway Down Highway 22 and outer raceway Up Highway UHW 20.R62, R63 be respectively level to vertical to eccentric throw.R17 is a steel ball size, and R64 is the raceway radius, generally designs R64=0.5 * R17+sqrt (R62 * R62+R63 * R63).The pivoting support raceway grinding mainly refers to the grinding of interior raceway Up Highway UHW 10, interior raceway Down Highway 12, outer raceway Down Highway 22 and outer raceway Up Highway UHW 20.The emery wheel that the raceway grinding is used requires its bus consistent with the raceway bus in theory, sees Fig. 2, when producing by emery wheel driver part 5, emery wheel 4 rotatablely moves, outer ring 1 also is rotated with certain speed, and emery wheel 4 near raceway, then produces the grinding campaign with certain speed simultaneously.Workpiece then forms desired raceway through a certain amount of grinding.In like manner, the grinding method of outer ring 2 is consistent therewith, sees Fig. 3.
Through after certain grinding, emery wheel can obstruction, passivation and can't carry out grinding, need repair it.
Among the present invention, adopt 8 pairs of emery wheels 4 of diamond pen to repair, its basic structure as shown in Figure 4, corresponding typical machine tool is configured to X-axis, Z axle, C axle and main shaft S axle.Before the crushing, set up emery wheel coordinate system and diamond pen coordinate system, the M point is the zero point of emery wheel among the figure, and diamond pen is horizontal, and promptly 0 °, this moment, the relative position of emery wheel position and diamond pen was determined.With emery wheel 4 rotatablely moving of self is main motion, the level and the vertical feed rectilinear motion that drive emery wheel 4 by emery wheel horicontal motion mechanism 6 and emery wheel vertical movement mechanism 7 replace its circular interpolation motion, and diamond pen rotational motion mechanism 9 drives diamond pen 8 rotations, the finishing of realization emery wheel.Horicontal motion mechanism 6 is X to, the i.e. ball-screw assistant drive device of horizontal direction, and emery wheel vertical movement mechanism 7 is Z to, the i.e. ball-screw assistant drive device of vertical direction.
During crushing, determine that at first emery wheel bus center overlaps the position with the Buddha's warrior attendant nib, promptly Z to.As shown in Figure 5, the tool setting of emery wheel upper surface, diamond pen is in 90 ° of upright positions.Make nib contact workpiece surface a little, promptly golden Pen nib 80 contact emery wheel Up Highway UHWs 40 are write down coordinate figure R10.
In like manner, as shown in Figure 6, Z is to the tool setting of emery wheel lower surface, promptly golden Pen nib 80 contact emery wheel Down Highways 41, diamond pen is in-90 ° of upright positions, writes down coordinate figure R11, half of these two coordinate figure sums then be the Z of emery wheel to the tool setting value, promptly parameters R 12.
As shown in Figure 7, when emery wheel Z when coordinate figure is in R12, and diamond pen is in 0 ° of position, makes nib contact workpiece surface a little, writes down X to coordinate figure, then be X to the tool setting value, promptly parameters R 14.
In theory, the emery wheel 4 after the finishing, its bus with should be just the same with the raceway bus, but in reality processing, the numerical control products of low side can not carry out three interlock circular interpolation, therefore must carry out discretization by raceway, when discretization to a certain degree the time, machining accuracy satisfies the requirement of grinding.As shown in Figure 8, be the processing schematic diagram of emery wheel of the present invention.According to the requirement of finishing, the nib 80 of crossing diamond pen is accomplished the vertical line of rotation, and this vertical line overlaps with the normal of emery wheel bus, and the contact point of diamond pen and emery wheel is exactly the nib 80 of diamond pen.If the nib of diamond pen 80 is a parameters R 100 to the vertical range of rotation, be super heart amount, its sign determines with the inter normal direction of emery wheel bus, and is consistent with inter normal then for just, otherwise then for negative.If during grinding, in a certain moment, diamond pen is in the θ angle, and the abrasive wheel grinding wheel arc center is in the S1 position, and this moment, contact point overlapped in the P1 position with the diamond pen nib, and the diamond pen axis is vertical with the tangent line of raceway bus.When diamond pen rotated a minute angle Δ, the diamond pen nib forwarded the P2 position to, and in order to guarantee the correct of grinding position, the emery wheel feed motion make to put accordingly on the bus to overlap in the P2 position with the diamond pen nib, and then the abrasive wheel grinding wheel arc central motion is to the S2 position.Δ is discrete resolution amount.After Fig. 9 is discretization, grinding wheel movement track and nib movement locus in one little section, the diamond pen nib forms a circular arc, and emery wheel is then walked straight line.After analyzing as can be known discretization thus, error appears in little section pars intermedia branch of crushing.This error is relevant with Δ.It is excessive that Δ is got, and error is excessive, and machining accuracy is not enough; That gets is too small, and amount of calculation is bigger than normal.Δ of the present invention is got 0.3 °～0.7 °.
As the finishing Up Highway UHW process status figure of Figure 10 for emery wheel of the present invention, be divided into 4 step: step I, emery wheel is in dead-center position, and center of arc is in the D1 position; Step II, emery wheel are in the tool setting point, and diamond pen is in 0 ° of position, and center of arc is in the D2 position; Step II I and IV are the dressing process of emery wheel, and to Step II I, center of arc moves to the D3 position by the D2 position, is calculated as follows from Step II.
Center of arc is moved to the horizontal displacement of D3 position by the D2 position:
X
D2-D3＝R64-R64cosθ+R100-R100cosθ；
Center of arc is moved to the vertical displacement amount of D3 position by the D2 position:
Z
D2-D3＝R64sinθ+R100sinθ。
To step IV, center of arc moves to the D4 position by the D2 position, is calculated as follows from Step II:
Center of arc is moved to the horizontal displacement of D4 position by the D2 position:
X
D2-D4＝R64-R64cos(θ+Δ)+R100-R100cos(θ+Δ)；
Center of arc is moved to the vertical displacement amount of D4 position by the D2 position:
Z
D2-D4＝R64sin(θ+Δ)+R100sin(θ+Δ)；
Therefore from Step II I to step IV, center of arc moves to the D4 position by the D3 position, is calculated as follows:
Center of arc is moved to the horizontal displacement of D4 position by the D3 position:
X
D3-D4＝X
D2-D4-X
D3-D4＝R64cosθ-R64cos(θ+Δ)+R100cosθ-R100cos(θ+Δ)；
Center of arc is moved to the vertical displacement amount of D4 position by the D3 position:
Z
D3-D4＝Z
D2-D4-Z
D3-D4＝R64sin(θ+Δ)-R64sinθ+R100sin(θ+Δ)-R100sinθ；
Obtained the grinding motion formula of discretization this moment.When the D3 position is a certain little section of grinding, emery wheel processing stations starting point, the D4 position then is an emery wheel processing stations terminal point.According to the feeding displacement of this formula control emery wheel, the Δ of diamond pen rotation simultaneously angle by continuous circulation, thereby realizes crushing.In like manner, the finishing of Down Highway is the same with the finishing principle of Up Highway UHW, and the reference axis travel direction is carried out according to concrete Machine Tool design.
According to above analysis, the flow process chart of designing program is seen Figure 11.Specific procedure is as follows.
