Abstract:
Motorized indexed measuring head for a machine for measuring three-dimensional coordinates. Comprises one, two or more re-orientable elements to orient a probe feeler according to a plurality of indexed orientations. The orientable elements are guided in their rotation and sliding movements by undercut bushings and undercut shafts. The arrangement of the undercuts allows an accurate guiding in the rotation movement without impairing the indexing accuracy.
Abstract:
Method enabling a command to switch the measure mode to be entered in a single vertical axis dimension-measuring column. The mode witch command is entered by pressing the probe tip against the piece to be measured during a time interval greater than a predetermined value. The measuring and displaying system then engages in a search mode of the turn-back point of said piece to be measured.Application: measurement of inner or outer diameters by means of a single-axis measuring column. The method allows the hole's minimal and maximal points to be determined with a minimum of handling operations.
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.
Abstract:
Trigger probe, constructed on the principle of the Boys connection, serving to detect the contact between the probe's stylus and a piece to be measured, comprising an electric circuit with at least one switch, whose contact elements are positioned by means of several connecting elements of the circuit.
Abstract:
Electronic measuring instrument equipped with a removable intelligent processing and radio communication interface. The interface allows managing additional features such as bidirectional communication of commands and measurement data with printers, computers or other external devices, as well as the transmission of instructions or measurement programs to the instrument. The radio interface may be connected with several measuring instruments such as callipers, micrometers, comparators or height gauges. It is integrated into the lid of the battery compartment of the instrument, so that it can be installed and removed easily and without impairing the seal. The cover also includes an extra battery for the processing and radio transmission interface.
Abstract:
The positioning and measuring system includes a coordinate positioning machine comprising a movable spindle (60) movable relative to a reference surface 30, a rotor (100) rotatably connected with the movable spindle, an actuator (500) for driving the rotor (100) in rotation around a rotation axis (65), and a coordinate probe (150, 190) detachably connectable to the rotor (100) for measuring coordinate of points (350) of a workpiece (200, 201, 250) along a path resulting from the composition of a translation movement of the spindle (60) and a rotation of the rotor (100). The points (350) are offset (r) with respect to the rotation axis (65) of the rotor (100).
Abstract:
A method for scanning a surface of a workpiece using a scanning probe 2 mounted on a support 3 on a coordinate measuring machine 4. The support contains drive means 5, 7 for actuating the movement of the scanning probe 2 relatively to the support 3. The method further involves detecting means 9 to measure a contact force F applied between the tip 10 of the probe and the surface 1, control means 13 coupled to the drive means, and memory means 14 for storing theoretical profiles 19 and coordinates 20 of the surface. This method is characterized by the fact that the control means 13 adjust the actuation of the drive means 5, 7 along a scanning path 18 in order to maintain the contact force 11 within the defined range of values 15 during the whole scanning operation along the scanning path 18.

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.
