Description
Technical field
The present invention relates to a kind of grinding bearing roller trimming wheel technology, particularly a kind of curve trimming device that is used for grinding bearing roller big arc.
Background technology
The method of present domestic trimming wheel circular arc mainly adopts grinding wheel arc dresser and two kinds of structures of emery wheel trimmer.
(1) grinding wheel arc dresser
Using grinding wheel arc dresser to carry out dressing technique is traditional grinding wheel dressing method that bearing grinder generally adopts, grinding wheel arc dresser mainly partly is made up of bow type bearing, bow type revoliving arm, servomotor or rotary oil cylinder etc., diamond pen is installed on the bow type revoliving arm, bow type revoliving arm is controlled by servomotor or rotary oil cylinder, does left and right sides gyration and realize emery wheel is repaired on bow type bearing.When the process larger sized arc radius, the size of bow type bearing, bow type revoliving arm will be very big, thereby its rigidity, intensity can't be guaranteed, so this grinding wheel arc dresser can't be repaired bigger abrasive wheel grinding wheel arc.
(2) emery wheel trimmer
The operation principle of emery wheel trimmer is by the belt wheel transmission emery wheel to be rotated by motor.When crushing, one-shot forming, trimming speed is fast but also can repair out the complicated curve of structure.But adopt this trimmer to come trimming wheel, have relatively high expectations for the rigidity of trimmer, simultaneously, different curve shape workpiece also need to join different emery wheels, and cost is very high.
Therefore, these two kinds of trimmers all are not suitable for bigger abrasive wheel grinding wheel arc finishing.
Summary of the invention

The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
The curve trimming device that the present invention is used for grinding bearing roller big arc adopts at the x of general-purpose grinder axle, the interpolation planker of 90 ° of placements of the secondary one-tenth of two on the y axle, the compensation planker, single-point is trimmer fixedly, servomotor and screw pair, the interpolation planker of 90 ° of placements of two secondary one-tenth is x axle interpolation planker and y axle interpolation planker, interpolation planker and servomotor are connected the two ends of screw pair respectively, the x axle, it is reciprocating that the servomotor of y axle drives the interpolation planker by screw pair, the movement locus of two secondary plankers is set by the shape of orthodrome curve, during curve finishing, at the x axle, the interpolation planker of 90 ° of placements of the secondary one-tenth of two on the y axle is placed with emery wheel at an angle along the origin of coordinates is left-handed, two secondary interpolation plankers are provided with movement locus along the orthodrome curve, by the left-handed angle of initial point eliminate emery wheel correction pen nib in the crushing process because the error of backlash that the backward rotation of ball-screw causes realizes reducing rounding error, improve dressing accuracy.The interpolation planker of 90 ° of placements of two secondary one-tenth is eliminated because the direction of ball-screw is rotated the error of backlash that causes along left-handed 30 ° of coordinate, 45 or 60 ° and the angled placement of emery wheel.
The primary importance of the relative emery wheel of two secondary interpolation plankers as shown in Figure 1, when trimming wheel, a crushing nib is finished crushing as moving interpolation in two (x, y axle) directions by two secondary interpolation plankers, promptly successively through the 1: 1, second: 2, thirdly 3, the the 4th: 4 and the 5th: 5.For y axle interpolation planker, a finishing nib is to move along a direction (y axle positive direction) all the time, but for x axle interpolation planker, a finishing nib is x planker positive directions 1: 1, second: 2, thirdly 3, through thirdly after 3, the 4th: 4 with the 5th 5 one-tenth in the other direction, promptly feed screw nut moves round about, feed screw nut and leading screw gap make transmission system dead zone error occur, the wheel face precise decreasing that repairs.
The second place of the relative emery wheel of two secondary interpolation plankers as shown in Figure 2, when trimming wheel, a crushing nib is still successively through the 1: 1, second: 2, thirdly 3, the the 4th: 4 and the 5th: 5.For x axle interpolation planker, a finishing nib is to move along the positive direction of x axle all the time.For y axle interpolation planker, nib also is a y axle positive direction through the 1: 1, second: 2, thirdly 3, the 4th: 4 and the 5th: 5 successively all the time, go directly 1: 1 after arriving the 5th: 5, repair next time, feed screw nut is done positive and negative both direction motion never again in the crushing process, the error of backlash of having eliminated the ball-screw backward rotation and having caused makes the curve precision higher.The 1: 1 and the 5th: 5 is initial and end point, though there is the unstable period of vibration, 1: 2 (with the emery wheel contact point) is preceding entering, and has reached steady working condition.
During the machining bearing roller, better in order to make surface roughness, profile tolerance, improve two secondary interpolation planker movement locus display precisions simultaneously, a secondary grating chi is installed between each secondary interpolation planker.As shown in Figure 3, between last interpolation planker 6 and following interpolation planker 7, install grating chi 8 and following grating chi 9, last grating chi 8 and following grating chi 9 form closed-loop system with servo-drive system, servomotor and screw pair 10, and screw pair 10 is connected with servomotor, following interpolation planker 7.Make feed screw tension and compression, reverse precision and non-linear factors such as frictional damping characteristic and gap all are included in the Position Control ring, improve the stability of system.Can also compensate simultaneously the influence of various errors, gap and interference in the mechanical driving device, the positioning accuracy height can reach ± 0.001mm.
In order to guarantee the linearity of interpolation planker, when processing interpolation planker, to guarantee contour and surface roughness equates to two guide rail installed surfaces of same secondary interpolation planker, promptly on x axle, the y axle interpolation planker contour and surface roughness equates to two guide rail installed surfaces of same secondary interpolation planker.When the mounting guide rail slide block, notice that the slide block that every guide rail is joined all has different marks, can not adorn instead, promptly every guide rail slide block of joining all has corresponding mark, and guide rail and slide block are corresponding one by one.
Two secondary interpolation planker peripheries are provided with protective cover, take labyrinth and scraping article to cooperate.Two sides at the interpolation planker increase backplate, make the one side of backplate block grinding water and enter interpolation planker inboard, and overhead kick is installed the double-lip seal scraping article in interpolation supporting plate down in a side of backplate, when the interpolation planker moved, grinding fluid and rubbish were isolated from outside the interpolation planker fully.Such double protection pattern even under the situation that grinding fluid splashes, also can be carried out favorable protection to the guide rail and the leading screw of inside.For operating system, change different workpiece and add man-hour, need not to reset again concrete parameter of curve, as long as on guidance panel, import arc radius.
The interpolation planker that the embodiment of the invention is enumerated is in order to help to illustrate the present invention along the left-handed angle of the origin of coordinates; in the practical operation; as long as it all is feasible that other left-handed angles do not make ball-screw generation backward rotation cause error of backlash, should all be considered as dropping in the scope of protection of the invention.
