Abstract:
Motorized indexed measuring head for a machine for measuring three-dimensional coordinates. Includes a double-action actuator to pass from a locked state, wherein any rotation of the probe feeler is prohibited, to an unlocked state, wherein the feeler can be oriented along two axes by two servomotors. The locking and unlocking mechanism is independent from the gravitational force and can operate whatever the orientation of the measuring head.
Abstract:
Motorized indexed measuring head for a machine for measuring three-dimensional coordinates. The orientable axes are actuated by motors rigidly supported on bearings or ball bearings. The rotation is transmitted to the re-orientable elements by transmission elements having sufficient play so that the indexing accuracy is not impaired.
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 probe for a machine for measuring coordinates, including a contact feeler (12), relatively mobile relatively to a fixed organ (1) and held in a defined and repeatable resting position by a spring (21). The probe comprises an electric circuit to detect the displacements of the feeler (12). The resting position is defined by six contact points distributed around the axis of the feeler to obtain a uniform sensitivity to lateral forces.
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:
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.
Abstract:
Height-measuring column comprising a supporting frame fastened to a base, said supporting frame determining the measuring axis, it being possible to regulate the perpendicularity between the supporting frame and the base and method for regulating the perpendicularity of a height-measuring column relative to a reference surface by regulating the perpendicularity between the supporting frame and the base of said height-measuring column.
