A beam for a measuring machine is constituted by a plurality of extruded beam elements, which are set alongside one another and welded together so that each forms a portion of the cross section of the beam itself; the beam elements and the beam have a hollow section shaped like an equilateral triangle.

Beam for a co-ordinate measuring machine, method for its production, and measuring machine provided with said beam

A coordinate measuring machine () comprising a base () provided with guides () parallel &#x25cf; to a first axis X, a first carriage () mobile on the guides () along the axis X and provided with an upright (), a second carriage () carried by the upright () and mobile along a second vertical axis Z, and a horizontal arm () carried by the second carriage () and mobile along a third horizontal axis Y perpendicular to the axis X; the guides () of the first carriage () are arranged underneath a top wall () of the base (), which is therefore flat and treadable.

Coordinate measuring machine

A coordinate measuring machine () comprising a base () provided with guides () parallel to a first axis X, a first mobile carriage () on the guides () along the axis X and provided with an upright (), a second carriage () carried by the upright () and mobile along a second vertical axis Z, and a horizontal arm () carried by the second carriage () and axially mobile along a third horizontal axis Y perpendicular to the axis X; the first carriage () comprises a base () provided with a first portion () coupled to the guides () and a second portion () rigidly connected to the upright (), releasable connection means () for reciprocally connecting the first portion () and the second portion () of the base (), and articulated connection means () between the first portion () and the second portion () of the base to allow the upright () to be tipped when the releasable connection means () are released.

Horizontal-arm coordinate measuring machine

A coordinate measuring machine comprising a base provided with guides parallel to a first X axis, a first carriage mobile on the guides along the X axis and provided with an upright, a second carriage carried by the upright and mobile along a second vertical Z axis, and a horizontal-arm carried by the second carriage and axially mobile along a third horizontal Y axis perpendicular to the X axis; a counterweight, fastened to the second carriage by means of a belt, is mobile along the Z axis within the upright and is provided with wheels in contact with side walls of the upright.

A supporting element having a base positionable on a table of a measuring machine; a rod in turn having a vertical axis, and which is fitted to the base and movable axially to adjust the height of the supporting element; and an end portion fitted to the rod and cooperating with a position reference fixture moved by the machine; the supporting element also having locking means interposed between the rod and the end portion, and which are releasable to permit a limited amount of movement of the end portion with respect to the rod when configuring the supporting element.

Reconfigurable supporting element, particularly for measured parts on a

A gauge for measuring parts and presenting a number of reconfigurable supporting elements, each having a first portion positionable on a reference surface, and a second portion positionable in relation to the first portion in a direction perpendicular to the reference surface; and a number of orientable measuring modules, each fitted to the second portion of a respective supporting element and presenting a respective linear position transducer; the supporting elements and respective measuring modules being so arranged as to define a number of discrete points for supporting the part for measurement; and each transducer detecting any departure of the actual position of a respective point of the part from a theoretical reference position of the point.

Part measuring gauge

A fixture for positioning and supporting parts for measurement on a measuring machine, the fixture presenting a number of reconfigurable supporting elements, each presenting a first portion positionable on a reference surface of the measuring machine, a second portion positionable in relation to the first portion in a direction perpendicular to the reference surface, and clamping members for clamping the first portion in relation to the reference surface and the second portion in relation to the first portion; and a gripping tool movable automatically by the measuring machine and cooperating with the second portion of a supporting element in a position of mutual engagement to set the supporting element in a predetermined position; the gripping tool presenting control means, which, in the aforementioned position of mutual engagement, provide for simultaneously releasing the clamping members clamping the first portion and second portion of the supporting element to enable the supporting element to be repositioned by means of a single gripping operation.

Reconfigurable supporting fixture, particularly for a measuring machine

An assembly for supporting and guiding a movable member of a machine along an axis 'X' relative to a support member of the machine. The assembly includes first and second slide surfaces on the support member lying in planes which intersect with each other and extend parallel to the 'X' axis, a pair of pneumatic bearing pads are fixed to the movable member and are slidable on respective slide surfaces. A third slide surface is formed on the support member and extends parallel to the 'X' axis in a plane inclined to the planes including the first and second slide surfaces. A third bearing pad is fixed to the movable member and is slidable on the third surface in an arrangement to balance the loads exerted by the first and second bearing pads.

A measuring machine includes a base, a portal movable on the base along a first horizontal axis and having a cross-member extending along a second horizontal axis perpendicular to the first, a carriage carried by the cross-member and movable along the second axis on a guide formed on the cross-member, and a measuring head carried by the carriage and movable relative thereto along a third, vertical axis; the guide defines a main slide plane inclined at 45.degree. to the reference plane, the cross-member and the carriage having elongate sections in directions parallel to this main slide plane

Measuring machine

A fixture comprising a number of rearrangeable elements; a hand operated by a robot and designed to position the aforementioned rearrangeable elements on a reference table; and a number of part supporting and clamping means. The aforementioned rearrangeable elements comprise a tubular casing sliding on an air-cushioned pad; and a rod designed to slide axially inside the aforementioned tubular casing and on to the top portion of which are secured the aforementioned supporting and positioning means. (FIG. 1).

Rearrangeable supporting and positioning fixture, particularly for parts

The shoe has a flat surface which can slide with reduced friction on a guide surface, means for introduction and distribution of compressed air to generate a supporting air cushion between the said surfaces, and a plurality of permanent magnets generating a force of attraction between the shoe and the guide surface in such a way as to cause the shoe itself to stop immediately when the supply of compressed air is interrupted.

Air cushion shoe

The device comprises a series of tool carriers each of which is provided with a tool, a connector tang and aseries of three abutments disposed substantially around the axis of the tool and in a plane orthogonal to the axis itself, a rack provided with a plurality of seats each of which is able to support a tool carrier, a support unit fixed to the head of the machine is provided with a series of frontal surfaces operable to constitute bearings for the said abutments; this unit is provided with connector means operable to grip the connector tang of one of the tools, and displacement means operable to support the connector means and to displace it with respect to the support unit in the direction of the axis of the tool from a first position in which the abutments of the said series of abutments are at a predetermined distance from the frontal surface of the first defined series, to a second position in which the abutments themselves are in contact with the frontal surfaces, the displacement from the first to the second position being controlled by a spring.
