A tram adapter apparatus, kit and method is used with an alignment tool to check the alignment of the spindle and the table of a machine tool. The alignment tool has two or more indicators retained in a spaced apart relation to the spindle of the machine tool. A tram adapter body is interposed between the indicator body and the stop of one of the indicators, moving the indicator tip to a retracted position. The other indicator remains in the deployed position and may be used to tram the table of the machine tool to check the alignment between the table and spindle.

A gauge (10) for a three-dimensional coordinate measurer fixed onto the measurement table of the three-dimensional coordinate measurer to measure by utilizing the center-to-center distances of spheres and the axis and plane formed of the centers of the plurality of spheres, wherein fitting grooves (2) are formed in the surface of a cylindrical or conical holding body (1) and spherical fixing members (4) having the plurality of spheres (3) arranged thereon are fixedly fitted to the fitting grooves (2), and a standard ring gauge (5) is formed in the holding body (1), whereby three items, that are, scale calibration, straightness, and squareness of the three-dimensional coordinate measurer can be evaluated simultaneously merely by one measurement.

A carpenter's square that can have the arms thereof separated for ease of storage and joined together during use includes a over-center latch arrangement designed to be no thicker than the thickness dimension of the arm members and which, when operated, tightly clamps the arms of the square at right angles to one another. A first arm of the square has an opening formed through the thickness dimension thereof along with alignment bores extending inwardly from a side edge thereof on either side of the opening. The second arm includes the over-center latch pivotally mounted in a slot or channel and includes a latch plate pivotally joined to a coupling member having a head thereon designed to fit within the opening on the first arm member. When the latch plate is manually actuated so as to reside within the slot of the second arm, the head on the coupling member cooperates with an edge defined by the opening in the first arm to tightly clamp the first and second arms one to the other.

An improvement to a measuring table for fabricated plate products, such as sheet metal and the like. A measuring table having legs for support of flat table surfaces with opposite sides and ends is equipped with a straight reference gauge extending squarely across the table surfaces near one end and a slot extending at right angles to the straight reference gauge. The improvement to such a measuring table comprises a linearly stationary yet pivotal contact mounted in the slot adjacent to the reference gauge, a pivotal contact movable in the slot by a carriage slide mounted to the underside of the table, and a microprocessor operatively connected to the contacts to receive, store, process and display the measurements therebetween. The method of this invention comprises the steps of spreading the contacts to accommodate between them a plate laid on the table surface, positioning one corner of the plate against the linearly stationary yet pivotal contact, sliding and pivoting the movable contact against an opposing corner to generate a first measurement of the plate's diagonal, repeating the above steps to generate a second measurement across another diagonal, and comparing the deviation between the first and second measurements to a predetermined acceptable limit. Those plates having excessive deviations between the diagonals are rejected as out of square.

A cylindrical square for inspecting the angular relationship of a test surface to a vertical support surface on a vertical support member. The flat surface being intended to be perpendicular to the test surface, a dial indicator having a sensing member and a supporting member supported on said support surface. Said dial indicator support being adapted to have a dial indicated thereon to be slid along the top of said cylindrical surface of said cylindrical square whereby the dial indicator will indicate errors in the angular relationship of the vertical surface to the flat test surface.

A gauge for determining whether a conductive element, such as a cutting element, fence, gauge rod, gauge shaft, or guiding surface is oriented at a predetermined angle with respect to a reference surface is disclosed and claimed. The gauge includes an indicator, an electrical energy source, and at least one pair of contacts. When the gauge is placed on the reference surface, the contacts are abutted against the conductive element, and the conductive element is oriented at the predetermined angle, a series circuit is completed between the indicator and the energy source. As one example, the gauge can be used to ascertain the angle of a saw blade with respect to a saw table.
摘要:
An instrument for aligning the spindle of a vertical milling machine perpendicular to the milling machine table or work surface. The instrument comprises a first right circular cylinder member that is coaxially attached to the machine spindle about a first axis. This is typically accomplished with the use of a spindle collet. A second pivotal member contains that portion of the first member protruding from the spindle collet. The second member allows rotational and axial freedom of the first member, and the first member is so contained that radial clearance between the first and second member is held to be negligible. The second member is constructed to provide for pivotal attachment to a third or main frame member about a second axis which is orthogonal but not necessarily coplanar with the first axis. The third member has provision for contact with the milling machine table at two points that define a third axis which is orthogonal but not necessarily coplanar with the second axis. A displacement indicator is affixed between the second and third members such that both acute and obtuse departures from perpendicularity between the first and third axes can be quantified.
