Abstract: Dimension measuring instrument having a probe moving along a measuring axis. An elastic transmission element allows the probe to move under the action of the measuring force. If necessary, the probe can be coupled rigidly with the instrument, for example to perform profile measurements or tracings. The instrument is entirely protected by a casing from liquid projections and dust, and the probe can be locked without opening the casing or accessing its inside.

Abstract: Touch probe including a fixed part (250), designed to be fastened onto a measuring machine or a machine tool, and a contact feeler (30) that is mobile and orientable on two independent axes (211, 212) along a multiplicity of directions indexed in space. An actuator (300) comprising antifriction rollers and a ball bearing allows the rotation axes (211) to be unlocked and any orientation to be selected with minimized friction. In locked position, the actuator (300) withdraws under the action of return springs (336) so as not to influence the indexing accuracy.

Abstract: Tool-switching device for a machine for measuring coordinates wherein the tool is fastened on the tool-carrier and held by the action of elements exerting an axial force. The locking force is taken over symmetrically by the elements of a Boys connection, which increases the repeatability of the connection; in one embodiment, two pins or spheres are driven by a sliding bushing provided with two “V”-shaped slits or with two lateral gorges. In the subsequent embodiments, the pins are replaced by spheres, by levers or by a stirrup.

Abstract: A vertical length measuring device (100) is disclosed that comprises a vertical guide (20), at least one carriage (35) that is led vertically by the guide (20), and a driving organ (130, 150) for the at least one carriage (35). A housing (120) placed around the vertical guide (20), the carriage (35) and the driving organ (130, 150), has a longitudinal opening (121), and is fastened at a foot (33) of the length measuring device (100). A measuring head (40) is placed outside the housing (120) and is connected with the carriage through the opening (121) of the housing (120). The invention is characterized in that behind the opening (121) of the housing (120) inside the housing (120), a baffle (125) is placed. This advantageously prevents penetration of oil, water and dirt from outside.

Abstract: Reference gauge for calibrating measuring machines whose reference dimension can be measured both on its inner size and by its outer size, thus making it possible to keep the reference dimension less than 15 millimeters, even for calibrating measuring machines equipped with probe tips having a diameter greater than that dimension. The calibration method with the aid of such a reference gauge comprises in certain cases the measuring of the calibrated distance between two outer surfaces of a protruding volume.

Abstract: Touch-triggered probe comprising a fixed part, designed to be fastened onto a measuring machine or a machine tool, and a mobile contact feeler that can be oriented on two independent axes along a multiplicity of spatial directions.

Abstract: Touch-triggered probe comprising a fixed part, designed to be fastened onto a measuring machine or a machine tool, and a mobile contact feeler that can be oriented on two independent axes along a multiplicity of spatial directions. The two axes of the probe comprise each an actuator for unlocking and adjusting the axes. The operation force is reduced as compared with the high effective indexing force by a demultiplying mechanism having an increasing transmission ratio, for making easier the operation in unlocked position. The indication elements can easily be read whatever the feeler's orientation.

Abstract: Column for measuring longitudinal dimensions (1) comprising: a supporting frame (2), a carriage (3) capable of moving along a measuring axis (z) along the supporting frame, a cable or belt (40) for moving said carriage along said measuring axis, a counterweight connected to said cable or belt so as to move in opposite direction from the carriage, a guiding surface for restricting the counterweight's movements. A play of 1 millimeter is provided between said counterweight and said guiding surface. This play is sufficient to avoid any contact between said counterweight and any guiding surface when said counterweight is displaced vertically.

Abstract: Column for measuring longitudinal dimensions (1) comprising: a supporting frame (2), a carriage (3) capable of moving along a measuring axis (z) along the supporting frame, a probe tip (44) connected to said carriage and designed to be brought into contact with the piece to be measured, a driving device of the carriage comprising a cable or belt (40) for moving said carriage along said measuring axis, a system for measuring the position of said carriage (3) along said measuring axis, a frame connected in an articulated manner to the carriage. The cable or belt are fastened to the frame. The articulation between the frame and the carriage allows at least one pivoting along a pivoting axis (x) parallel to the plane of said carriage. Advantages: the forces and moments exerted by the cable or belt are not exerted directly onto the carriage. The forces along an axis other than the measuring axis are absorbed by the frame.
