Abstract
Abstract Equipment for mounting workpieces in relation to a machine tool axis as pertaining to the spindle of a cutting, milling or drilling tool or the like, and on a machine tool table which can be placed in particular position relative to the tool. A support table is mounted on the machine tool table for turning on a second axis, which can be placed by the machine tool table in particular relation to the tool axis; a prism is mounted with one end face on the support table, so that at least two of the prism sides have similar distance from the second axis; at least two of the sides are provided each with an array of threaded fitting bores arranged in regular spacing along two coordinates on the respective side, the bores of the arrays being arranged to have similar position for similar dispositions of the two sides in relation to the tool. The prism sides have second bores respectively between four of the fitting bores as forming a quadrilateral, and suction into the second bores is provided for; the sides have grooves interconnecting the second bores; upon turning the table, each of the prism sides is selectably placeable into the same particular position in relation to the tool axis.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
180 words
Equipment for mounting and positioning workpieces in relation to a machine tool axis as pertaining to the spindle of a milling or drilling tool or the like, comprising: support means; a mounting prism having two parallel end faces and rectangular sides, the prism mounted with one of the end faces on the support means; at least two of the sides of the prism provided each with an array of first threaded, fitting bores arranged with regular spacing along two coordinates on the respective sides, the first bores of the arrays having similar location for similar positions of the two sides in relation to an axis; said sides having second bores respectively between four of the fitting bores as forming a quadri-lateral, the prism provided with means for providing suction in the second bores, the sides having channels, open to the sides and interconnecting the second bores; and means for providing relative displacement between two relative positions as between the tool axis and said prism, the tool axis having the same relative positions to said sides in each of said positions.
Claim 2
Dependent Claim
180 words
Equipment for mounting and positioning workpieces in relation to a machine tool axis as pertaining to the spindle of a milling or drilling tool or the like, comprising: support means; a mounting prism having two parallel end faces and rectangular sides, the prism mounted with one of the end faces on the support means; at least two of the sides of the prism provided each with an array of first threaded, fitting bores arranged with regular spacing along two coordinates on the respective sides, the first bores of the arrays having similar location for similar positions of the two sides in relation to an axis; said sides having second bores respectively between four of the fitting bores as forming a quadri-lateral, the prism provided with means for providing suction in the second bores, the sides having channels, open to the sides and interconnecting the second bores; and means for providing relative displacement between two relative positions as between the tool axis and said prism, the tool axis having the same relative positions to said sides in each of said positions.
Claim 3
Dependent Claim
75 words
Equipment as in claim 1, including mounting elements having threaded bores spaced corresponding to the spacing of the first bores, for bolting to the sides in predetermined position thereon, the mounting elements including at least two, one for each side, and having a fixed mounting post and bolted to the corresponding bores of the first plurality so that the post can assume the same position relative to the tool axis in each of said positions.
Claim 4
Dependent Claim
18 words
Equipment as in claim 1, wherein the remaining sides of the prism are provided with interacting clamping grooves.
Claim 5
Dependent Claim
13 words
Equipment as in claim 1, there being sealing elements disposed in the grooves.
Claim 6
Dependent Claim
57 words
Equipment as in claim 1, the prism being mounted on a turntable, the tool having axis whose position is independent from the rotation of the turntable, the two positions defined by rotation of the turntable over an angle necessary to place the sides into identical positions relative to the tool when its axis has a fixed position.
Claim 7
Dependent Claim
218 words
Equipment for mounting workpieces in relation to a machine tool axis as pertaining to the spindle of a cutting, milling or drilling tool or the like, there being a machine tool table, and tool and table can be placed in particular position relative to each other, comprising: a support table mounted on the machine tool table for turning on a second axis, the second axis being placed by the machine tool table in particular relation to the tool axis; a mounting prism having two parallel end faces and rectangular sides, the prism mounted with one of the end faces on the support table, so that at least two of the sides have similar distance from the second axis; at least two of said sides provided each with an array of first threaded fitting bores arranged in regular spacing along two coordinates on the respective side, the bores of the arrays having similar location for similar positions of the two sides; said sides having second bores respectively between four of the fitting bores as forming a quadrilateral, the prism provided with means for providing suction in the second bores, the sides having grooves interconnecting the second bores; eaCh of said sides being selectably placeable into the same particular position in relation to the tool axes upon turning the table.
Claim 8
Dependent Claim
218 words
Equipment for mounting workpieces in relation to a machine tool axis as pertaining to the spindle of a cutting, milling or drilling tool or the like, there being a machine tool table, and tool and table can be placed in particular position relative to each other, comprising: a support table mounted on the machine tool table for turning on a second axis, the second axis being placed by the machine tool table in particular relation to the tool axis; a mounting prism having two parallel end faces and rectangular sides, the prism mounted with one of the end faces on the support table, so that at least two of the sides have similar distance from the second axis; at least two of said sides provided each with an array of first threaded fitting bores arranged in regular spacing along two coordinates on the respective side, the bores of the arrays having similar location for similar positions of the two sides; said sides having second bores respectively between four of the fitting bores as forming a quadrilateral, the prism provided with means for providing suction in the second bores, the sides having grooves interconnecting the second bores; eaCh of said sides being selectably placeable into the same particular position in relation to the tool axes upon turning the table.
Claim 9
Dependent Claim
