An improved guide assembly for a honing mandrel including an elongated support member having opposite surfaces and spaced side edges, the contour of the elongated member being such that portions of the elongated member are able to flex relative to each other, at least two elongated parallel rack gear members having corresponding ends connected at spaced locations to extend in parallel relation extending perpendicularly from one of the opposite surfaces of the elongated member, and an elongated work engaging member having a first portion positioned adjacent to the elongated support member on the surface thereof opposite from which the rack gears extend and a second portion extending outwardly from the first portion for engaging a surface to be honed, and means connecting the work engaging member to the elongated member. The subject guide assembly may also include a construction wherein the support member has two separate portions each independently angularly movable relative to the other and to the portions of the support member to which the rack gears are attached, a separate elongated work engaging member being attached to each independently movable portions of the support member.
A guide assembly for a honing mandrel comprising an elongated member having opposite surfaces and spaced side edges, means including slot means formed in the elongated member weakening the elongated member to form the member into adjacent first and second elongated portions on opposite sides of the slot means which portions are capable of relative angular movement therebetween, at least two elongated parallel rack gears having corresponding ends connected at spaced locations to extend perpendicularly from one of the opposite surfaces of said first portion of the elongated member, an elongated work engaging member having a first portion positioned adjacent to the second position of the elongated member and a second portion extending outwardly from the first portion for engaging a work surface to be honed, and means connecting the work engaging member to the elongated member.
In a honing mandrel having opposite sets of work engaging assemblies including an opposed set of honing assemblies and an opposed set of guide assemblies and rack and pinion gears for moving the assemblies radially to expand and contract the honing diameter, the improvement comprising similar guide assemblies each having a work engaging guide member and means for supporting the work engaging guide member, said support means on each guide assembly including a support member formed of relatively hard but somewhat resilient material having opposed surfaces and connected first and second portions, said support member being weakened between the first and second portion to facilitate limited relative angular movement therebetween, at least two spaced rack gear members attached to extend in parallel relation perpendicularly from one of the opposed surfaces of the first portion of the support member, and at least one work engaging guide member attached to the other opposed surface of the second portion of the support member, the second of said connected portions of the elongated member extending at least in part between where the rack gear members are connected to the first portion.
In a honing mandrel having opposed sets of work engaging assemblies including an opposed set of honing assemblies and an opposed set of guide assemblies and cooperating rack and pinion gear means on the mandrel and the assemblies for moving the assemblies radially to expand and contract the honing diameter of the mandrel, the improvement residing in the construction of the guide assemblies each comprising a work engaging guide member and means for supporting the work engaging guide member, said support means on each guide assembly including an elongated support member having opposed surfaces and elongated connected first and second portions and means therebetween which weaken the support member to facilitate limited relative angular movement between the first and second portions, at least two spaced rack gears attached extending perpendicularly from the first connected portion of the elongated support member and from one of the opposed surfaces thereof, and at least one work engaging guide member attached to the second of the connected portions of the elongated support member on the other opposed surface thereof whereby the second portion of the elongated support member and the work engaging guide member attached thereto are able to flex relative to said first portion of the elongated support member.
A guide assembly for use on a honing mandrel having opposed sets of honing and guide assemblies each supported and moved by rack gears engageable with a pinion gear, each of said guide assemblies including an elongated support member having opposed surfaces and spaced side and end edges, spaced elongated rack gears having opposed ends, means connecting corresponding ends of the rack gears to the elongated support member to extend outwardly therefrom in parallel spaced relation from one of the opposed surfaces thereof at locations adjacent to one of the side edges and the respective end edges thereof, first means including elongated means weakening the elongated support member at an intermediate location therealong between the spaced side edges to facilitate portions of the elongated member on opposite sides of the first weakening means to be able to move angularly relative to each other, second means including spaced substantially transversely extending means weakening the elongated member at spaced locations on the support member on one side of the first weakening means and between where the rack gears are connected thereto to form another elongated portion of the support member extending therebetween, said other elongated portion being able to move angularly relative to the rack gears and to the portions of the support member to which the rack gears are connected and independently of the portion of the elongated member on the opposite side of the aforesaid first weakening means, and a separate work engaging guide member attached to the support member on each opposite side of the first weakening means, one of said work engaging guide members extending over the area between the spaced substantially transversely extending second weakening means, said work engaging guide members being attached to the support member on the opposite surface from the rack gears.
A guide assembly for a honing mandrel comprising an elongated member having opposite surfaces and spaced side edges, means weakening the elongated member to form the member into adjacent first and second portions capable of limited relative angular movement therebetween, said means weakening including at least two spaced substantially transversely extending slots formed extending inwardly from one of the side edges of the elongated member, at least two elongated parallel rack gears having corresponding ends connected at spaced locations to extend in parallel relation extending perpendicularly from one of the opposite surfaces of said first portion of the elongated member, an elongated work engaging member having a first portion positioned adjacent to the second portion of the elongated member and a second portion extending outwardly from the first portion for engaging a work surface to be honed, and means connecting the work engaging member to the elongated member.
A guide assembly for a honing mandrel comprising an elongated member having opposite surfaces and spaced side edges, means weakening the elongated member to form the member into adjacent first and second portions capable of limited relative angular movement therebetween, said means weakening including an elongated slot formed extending between the first and second elongated portions of the elongated member along a substantial portion of the length thereof, said slot having transversely extending end portions, at least two elongated parallel rack gears having corresponding ends connected at spaced locations to extend in parallel relation extending perpendicularly from one of the opposite surfaces of said first portion of the elongated member, an elongated work engaging member having a first portion positioned adjacent to the second portion of the elongated member and second portion extending outwardly from the first portion for engaging a work surface to be honed, and means connecting the work engaging member to the elongated member.
