Abstract
The utility model relates to an omnidistance direction graded constant-speed planar lapping machine, which relates to a slide device for limiting the motion track of the planar lapping machine. The uniformity of the lapping stroke and speed of the planar lapping machine which eccentrically moves is poor, and a planetary motion grinder which makes hypocycloid tracks can not move evenly, and the parallelism of a workpiece plane is not easy to ensure because of the continuous inflection of large angle of the tracks. A slide bar (8) of an isolating disc of the utility model is arranged in a horizontal through hole in the isolating disc (3), wherein, the left end of the slide bar (8) of the isolating disc is fixed in the middle part of a left slide bar (9), and the right end of the slide bar (8) of the isolating disc is fixed in the middle part of a right slide bar (10); the slide bar (8) of the isolating disc, the left slide bar (9) and the right slide bar (10) are positioned at the same horizontal plane. The utility model can meet the requirement of identity of the lapping tracks because the motion track of each point on the surface of a workpiece to be lapped is the circumference of equal size, can get isotropic lapping surfaces because the lapping direction is gradually graded, and has good motion stability because the motion speed of each point on the workpiece plane is equal in size and constant corresponding to a lapping disc.
Description
Technical field: the utility model relates to the carriage of constraint plane grinder movement locus.
Background technology: current face lapping mill is from motion mode, and be divided into two big classes basically: a class is that separator is made eccentric motion, and another kind of is that separator is done planetary motion.The homogeneity of making the grinding stroke of face lapping mill of eccentric motion and speed is relatively poor, it is good that its Grinding Quality and grinding efficiency all are not so good as the planetary motion face lapping mill, and the planetary motion grinder of making the hypocycloid track is because of the continuous wide-angle inflection of track, motion is uneven, the workpiece planarization depth of parallelism is difficult for guaranteeing, form the planetary motion face lapping mill of epicylclic motion track by compound motion, it is better with all one's life that it grinds stroke, motion steadily, workpiece can be gone over the working surface of whole abrasive disk preferably, but in its major defect is, tens bearing pins on the outer disc dowel and the planetary plate tooth that is engaged with wear and tear easily, need frequent maintain and replace bearing pin and planetary plate.Above-mentioned several face lapping mill can not guarantee strictly that all the grinding movement velocity of each point on the surface of the work is definitely equal, can not guarantee that movement velocity is invariable in the surface grinding process.
The utility model content: the purpose of this utility model is a kind of omnidistance direction gradation type constant speed face lapping mill of development, it should have the movement velocity constant magnitude of workpiece planarization with respect to abrasive disk, and direction is along the tangential direction gradual change in proper order of circular path, parallel motion is done on the relative lap tool of workpiece plane, guarantee that each point is with respect to the slip distance equal (promptly grinding the homogeneity of stroke) of abrasive disk on the surface of the work, guarantee that the surplus that each point grinds off on the workpiece is identical, to guarantee by the flatness on grinding work-piece plane and the depth of parallelism, can make simultaneously on the abrasive disk wear extent of each point identical, make the geometrical precision of abrasive disk keep remaining unchanged for a long period of time, prolong the abrasive disk working face characteristics in service life.The utility model comprises top lap 1, following abrasive disk 2, separator 3, eccentric shaft 4, crank 5, abrasive disk carriage 6, main shaft 7, and it also comprises separator slide bar 8, left slide bar 9, right slide bar 10, slide block 12, slide block 11; Following abrasive disk 2 is fixed on the abrasive disk carriage 6, separator 3 be arranged on down abrasive disk 2 above, top lap 1 be arranged on separator 3 above, but separator 3 holding workpieces are movable between top lap 1 and following abrasive disk 2, main shaft 7 is arranged in the centre bore of abrasive disk carriage 6, fixedly connected with the left end of crank 5 in the upper end of main shaft 7, fixedly connected with the right-hand member of crank 5 in the lower end of eccentric shaft 4, the lower end of the upper end of eccentric shaft 4 and separator 3 flexibly connects, separator slide bar 8 is arranged in the horizontal through hole in the separator 3 and with it and is slidingly connected, the left end of separator slide bar 8 is fixed on the middle part of left slide bar 9, the right-hand member of separator slide bar 8 is fixed on the middle part of right slide bar 10, separator slide bar 8, left side slide bar 9 and right slide bar 10 all are on the horizontal plane, the two ends of left side slide bar 9 are separately positioned in the through hole 11-1 of two slide blocks 11 of homonymy and with it and are slidingly connected, the two ends of right slide bar 10 are separately positioned in the through hole 12-1 of two slide blocks 12 of homonymy and with it and are slidingly connected two slide blocks 11, slide block 12 is separately fixed on the frame.The utility model is single eccentric structure, and it is not only simple than planetary motion grinding machine structure, and grinds function than planetary motion and satisfy the specification requirement of process of lapping to motion and movement locus better.The movement locus that the utlity model has grinding work-piece surface each point is equal-sized circumference, satisfies the homogeneity requirement of grinding track; Each point is with respect to the movement velocity equal and opposite in direction of abrasive disk and invariable on the workpiece planarization, kinetic stability is good, workpiece grinds the tangential direction in proper order gradual change of direction along circular path, can avoid grinding tool on workpiece planarization, to produce and repeat track, being formed with line grinds, be easy to obtain isotropic high-precision lapped face, and help improving grinding efficiency.Workpiece grind direction along each to varying cyclically, can lower the influence of process system vibration and reduce requirement the abrasive disk surface roughness.Thereby reduce requirement to the device fabrication precision, and the raising of grinding tool roughness also helps retaining of grinding agent, the wearing and tearing of lap tool are even, are easy to guarantee by the flatness on grinding work-piece plane and the depth of parallelism, and the advantage that can prolong the service life of abrasive disk working face.The utility model also has easy to operate, and each parts of grinder are not easy to wear, use durable, reliable, grinding efficiency height, stay-in-grade advantage.
