Abstract
A honing template comprising longitudinally extending fingers adapted to surround a hone and the ends of which carry template segments having inner abutment surfaces that are spaced to abut non abrasive surfaces that are in line with the stones when the stones are expanded to the finished diameter of the cylinder being honed. The inner abutment surfaces of the segments have a radius at least as great as the maximum radius of the cylindrical surface to be honed. The fingers have a tapered surface that is abutted by an annular ring which is wedged over said tapered surfaces to adjust the radial position of the template segments.
Claims16
In a machine for increasing the diameter of holes in metals, and the like, having a spindle with a longitudinally extending axis of rotation and material removing elements which expand radially outwardly to increase the diameter of the hole, an improved diameter limiting device, comprising:
- a plurality of template segments for engagement by said material removing elements, an annular holder having an axially extending opening therethrough for receiving the spindle of the machine, said annular holder having generally exially extending fingers respective ones of which support respective ones of said template segments, a camming ring concentric with said fingers, said fingers having abutment surfaces thereon which are moved radially upon rotation of said camming ring, and torque sensing means for sensing the torque exerted on said template segments by said material removing elements, and whereby the torque sensing means can be utilized to indicate that the hole in the work has been enlarged to a predetermined diameter.
An adjustable honing template for limiting the radially outward movement of honing elements, said template comprising:
- a generaly tubular body having upper and lower ends and an axially extending opening therethrough, said body having a plurality of longitudinally extending fingers, said fingers having conically shaped external surfaces, a ring surrounding and abutting said conically shaped external surfaces, said ring and body having threaded engagement for positioning said ring longitudinally of said conically shaped external surfaces, and template segments carried by said fingers for abutment by the honing elements, and whereby rotation of said ring moves said template segments radially to adjust the limit of radially outward movement of the honing elements.
An adjustable honing template for limiting the radially outward movement of honing elements, said template comprising:
- a generally tubular body having an external flange on its upper end, an axially extending opening therethrough, and a conically shaped external surface which tapers outwardly and downwardly, said conically shaped portion of said body having a plurality of slots therethrough which communicate with said lower end to provide a plurality of depending fingers, said conically shaped external surface being threaded, a ring surrounding said fingers and having threaded engagement with said conical surface, and hardened arcuately shaped abutments carried by said fingers with their arcuate surfaces positioned to limit radially outward movement of the honing elements, and whereby rotation of said ring moves said abutments radially to adjust the limit of radially outward movement of the honing elements.
An adjustable honing template for limiting the radially outward movement of honing elements, said template comprising:
- a generally tubular body having an external flange on its upper end, an axially extending opening therethrough and a double tapered external surface having an apex adjacent the lower end of said body with tapers above and below said apex, said body having a plurality of slots therethrough extending from the lower end of said body upwardly through said double tapered surfaces to provide a plurality of depending fingers having double tapers on their external surfaces, a ring having internal threads of a diameter to engage said double tapered surfaces, said ring being of a material hard enough to form threads in said tapered external surfaces of said fingers, and hardened arcuately shaped abutments carried by said fingers with their arcuate surfaces positioned to limit radially outward movement of the honing elements.
An adjustable honing template having adjustable longitudinally extending fingers comprising:
- a body member having generally parallel axially extending fingers projecting therefrom, said fingers having abutment surfaces which are tapered longitudinally thereof, a template segment on each of said fingers, a ring generally paralleling said fingers and having a threaded internal or external surface thereon, camming means having engagement with said tapered abutment surfaces of said fingers, and means constructed and arranged to transform rotation of said ring into longitudinal movement to said camming means along said tapered abutment surfaces of said fingers, and whereby the radial position of said template segments is adjusted by rotation of said ring.
An adjustable honing template comprising:
- an annular body member having a longitudinally extending opening therethrough for receiving a hone, a plurality of generaly parallel fingers extending longitudinally of said annular body member, a template segment on each finger with said template segments defining a circle, a rigid adjustment ring positioned opposite said fingers, and a camming surface advanced over said fingers by rotation of said adjustment ring for wedging said fingers radially, and whereby the diameter of the circle defined by said template segments is changed by rotation of said adjustment ring.
