Description

The honing cutter of worm wheel pressure booster intermediate dead eye
Technical field
The utility model belongs to the Machining Technology field, is a kind of honing cutter of worm wheel pressure booster intermediate dead eye.
Background technology
In the processing of worm wheel pressure booster intermediate dead eye, to the requirement of its size, shape, roughness all than higher.Conventional process is: process right boring is earlier also stayed certain surplus, carries out honing with the honing cutter again, reaches the requirement of size, shape and roughness at last.With several (being generally 4) diamond dust reamers gradually the top gem of a girdle-pendant go surplus method to the phosphorus content height, hard fragility material, on-deformable casting pig effect is better.But a lot of shapes are arranged, structure, the special worm wheel pressure booster intermediate dead eye of material is difficult to honing with conventional honing cutter and goes out qualified products, the model of producing as U.S. Honeywell Inc. (Honeywell) is the intermediate dead eye of 791104 worm wheel pressure booster, this intermediate dead eye is by the cast form of QT520-10 spheroidal graphite cast-iron, graphite is spherical in this spheroidal graphite cast-iron, certain toughness is arranged, percentage elongation 〉=10%, this dead eye accounts for 60 ° wall at hole circle on week thinner, the thickness at the thin place of wall (P place on the figure) has only 4.5mm, and is that the half-moon groove of 7mm cuts off by width also at the middle part of slotted hole.Can produce the cutter relieving phenomenon with conventional honing cutter thin-wall part to flexible when micro cutting and the extruding like this.When wall unevenness was spared, deviation from circular from increased after thin part cutter relieving makes honing on the circumference.This intermediate dead eye is not a through hole in addition, but the other end has less hole, can not carry out omnidistance honing by dead eye fully with dead eye with the conventional honing cutter of diameter, the honing cutter will withdraw after arriving aperture place, dead eye bottom, make dead eye feed end many with contacting of honing cutter, the dead eye bottom contacts few with the honing cutter, this dead eye that just easily makes after the honing is that orifice end is greater than the bottom, hole.
Summary of the invention
The purpose of this utility model provides a kind of honing cutter of worm wheel pressure booster intermediate dead eye.This honing cutter can be to the toughness material, wall unevenness even, have thin-walled and the end has the worm wheel pressure booster intermediate dead eye of small structure to carry out honing, the dead eye after its honing all meets the requirements on size, shape and roughness.
The technical solution of the utility model is: the honing cutter of worm wheel pressure booster intermediate dead eye, 1-4 is installed the honing cutter on every multiaxis top gem of a girdle-pendant hole machine.Be characterized in: 6 are installed in the honing cutter respectively on 2 multiaxis top gem of a girdle-pendant hole machines.Each honing cutter is made the structure of a whole shape from top to bottom by handle of a knife, honing cutter hub, positioning section and guide section.Each handle of a knife cooperation with tapering is installed in multiaxis top gem of a girdle-pendant hole facility to be had in each spindle taper hole of tapering.The length of honing cutter hub is less than the length of worm wheel pressure booster intermediate dead eye.The diameter of the honing cutter hub of 6 honing cuttves is arranged in order from small to large, and the diameter of each honing cutter hub is the honing surplus in uniform distribution right boring rear bearing hole.The circumference of each honing cutter hub is the spline teeth structure of 12 five equilibriums.The diamond dust granularity of making the honing cutter hub is the 80-100 order.The width D of the spline tooth of honing cutter hub on circumference is 3mm.The guide section diameter carefully can matched in clearance stretches in the aperture below worm wheel pressure booster intermediate dead eye.
The course of work of the present utility model and principle are: the honing of dead eye is divided carry out for six times.Earlier carry out honing, from second to the 6th the honing cutter hub of diameter maximum carried out honing successively again with the less honing cutter of first honing cutter hub diameter.Behind six honing cuttves honing successively, make size, shape, the roughness of dead eye all reach the setting requirement.After the honing of six honing cuttves, because of the resistance to cutting minimizing of honing, the dead eye distortion reduces, and the circularity of dead eye can reach 0.002 scope.
The honing step of each honing cutter is: worm wheel pressure booster intermediate dead eye is aimed at the honing cutter move up, in the aperture below guide section enters dead eye, the honing cutter hub enters dead eye and advances to the dead eye bottom while rotating, the honing cutter hub rotates and just dead eye is carried out honing when advancing, and positioning section just in time touches the step in the dead eye when the honing cutter hub arrives the dead eye bottom.After brushing up against step, positioning section just immediately the worm wheel pressure booster intermediate is moved down and withdraws from the honing cutter.Because the length of honing cutter hub is less than the length of dead eye, so when the honing cutter hub entered the dead eye bottom, the top of dead eye just can not be subjected to honing again, can make the tapering of dead eye be not more than 0.003 like this.
Conventional honing cutter group is to distribute the honing surplus by 4 honing cuttves, and the application's patent makes into to distribute the honing surplus by 6 honing cuttves, and the radially honing degree of depth of every honing cutter is significantly reduced, and generally is controlled in the scope of 0.002m-0.005m.The diamond dust granularity of conventional honing cutter is the 100-120 order, and the application's patent increases thick to the 80-100 order, and the sharpness of honing cutter is improved greatly.The width of spline tooth on circumference of conventional honing cutter is 6-7mm, and the width D of spline tooth on circumference of the application's patent honing cutter reduces to 3mm.The length of conventional honing cutter hub is greater than the length of dead eye, the length of the application's patent honing cutter hub is less than the length of dead eye, so just reduced contacting of honing cutter hub and dead eye feed end place.That said structure has improved the honing cutter of the application's patent worm wheel pressure booster is made by toughness material widely, wall unevenness is even, have a honing quality that there is the dead eye of small structure thin-walled and end.
The utility model has the advantages that the honing cutter that a kind of worm wheel pressure booster intermediate dead eye is provided.This honing cutter can be to the toughness material, wall unevenness even, have thin-walled and the end has the worm wheel pressure booster intermediate dead eye of small structure to carry out honing, the dead eye after its honing all meets the requirements on size, shape and roughness.
