Abstract:
An analogue scanning probe with a connector detachably connectable to a movable support of a coordinate measuring system, the scanning probe including a touch at the tip of a stylus pivotally connected to the scanning probe according to a measure axis and a position encoder delivering a measure of the tilt angle of said touch about said measure axis, the scanning probe including one articulation comprised between said connector and said measure axis arranged to allow tilting of the scanning probe or of a part of the probe scanning probe.
Abstract:
A probe, connectable to a machine tool, has an electric generator and a driving element. The electric generator supplies an electric or electronic circuit with electric power, and the driving element is capable of relative rotation with respect to the stator of the electric generator. The driving element is not connected to any external energy source and can be set in rotation simply by activating the rotary axis of the machine tool. The driving element is either rotatably mounted on the probe itself or fixed on the reference table of the machine tool. The probe requires no additional connections to the machine tool on which it is mounted, besides the connection to the rotary spindle, which can be realized with a conventional tool-holder with a standardized tapered shank. The probe is fully compatible with standard probes and can be mounted and used with standard tool-holders without any adaptation.
Abstract:
Multidimensional coordinate measuring machine having a programming mode in which the measuring head can be displaced manually by an operator and a measuring mode in which a control unit is designed for automatically optimizing and reproducing the displacements of the measuring head recorded during the programming mode.
Abstract:
Tool rack for tools of a coordinate measuring machine, wherein the guiding and retaining surfaces of the tool rack are arranged on two planes offset vertically so as to cause the tool to tilt when it is unhooked. The inventive arrangement allows the mechanical efforts during uncoupling to be reduced appreciably. This reduction is due to the tool tilting and to the residual magnetic force being divided between three retaining point, with a positive effect on the coupling precision and on the tool positioning in the tool rack.
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:
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.
