Graph 1 taper covers part drawing to pursue sketch map of structure of part of bit body of 2 boring lever pursues my company is machining 3 pedestal sketch map the cone-shaped copper of large and conic crusher covers (craft difficult problem encountered when 1) seeing a picture: If the aperture inside the taper that copper covers is machined on W200 boring machine, boring lever journey is insufficient (1600mm) of the greatest distance, and cannot machine cone-shaped aperture; If the method of lengthen arbor is used to machine the aperture inside taper on lathe, grow too because of arbor cantilever, tigidity is insufficient, assure to machine precision requirement hard. To solve difficult problem of this one craft, we designed to be able to be in what taper hole of big length, big diameter machines on lathe of C61100 light-duty 8m to bore hole tool. 1 tool structure should bore hole tool by part of boring lever bit body (2) seeing a picture and two pedestal (composition of 3) seeing a picture. Machine the Kong Shi inside workpiece, need beforehand the circle outside thick car good work, so that secure work,go up in pedestal. Part of boring lever bit body by boring lever axis, gear 1 ～ 6, the composition such as half guide screw, mother, bit body, cutting tool. Among them, 1 solid couplet is in gear on boring lever axis, gear 4 with gear 5 solid couplet is together, pass bearing and connection of boring lever axis; Internal gear 5 with gear 6 clench the teeth, gear 6 pass key connection with guide screw; Half mother is used decide bolt solid couplet closely to be on bit body; Gear 2 with gear 3 for coaxial gear, through bearing fixed go up in lathe bed, be equivalent to a pair hanging annulus. The transmission principle of bit body of lever of boring of 2 jobs principle is shown 2 times like the graph. Electric machinery motion delivers boring lever through chuck, the gear that goes up in boring lever through solid couplet 1 with gear 2, 3 deliver gear 4, gear 4 can turn on boring lever, pass the internal gear with its solid couplet at the same time 5 pass motion secure the gear on guide screw 6, the axial that makes guide screw obtains classics decelerate thereby is mobile, obtain the poor speed ratio with boring lever at the same time. Cutting tool and boring cannot have opposite roll between lever, but can pass guide screw, half mother deputy make opposite shift with boring lever, make the cutting tool on bit body wins axial feed campaign thereby. Of cutting tool advocate the whirligig that motion is boring lever, can achieve different athletic rate through adjusting lathe chuck. 3 use methods bore hole with this the operation move of the aperture inside tool treatment cylinder is as follows: ① is pressed assemble a structure to assemble a tool; Park of ② general workpiece two pedestal center; Axis of lever of ③ general boring from workpiece cross inside aperture, workpiece one aspect of the matter lives with top top, another end outfit is placed on chuck, the circle outside carrying boring pole searchs clamp; ④ tries cut inside aperture, cut a circumstance to adjust cutting tool according to trying, can press the aperture inside blueprint treatment next. Machine the Kong Shi inside taper, need to adjust the boring pole that chuck carries only, make line of boring lever axes and line of work axle center become half cone angle can. Effective treatment makes clear, should bore hole the dimension precision that the tool can assure completely to taper hole of big length, big diameter is machined, coaxial is spent reach exterior surface roughness. Because pedestal uses a center to wear a form, the center is adjustable, because this also can be used at machining other similar work, extended the process capability of existing equipment thereby.
