Abstract:
The present invention provides an automatic positioning system for measuring workpieces that comprises an actuator module in which a tool is arranged to clamp a workpiece, the actuator module being able to be transported and activated, through a valve block, by a robot commanded by a processing unit, such that the robot is prepared to transport the actuator module and locate it on a work plate, in addition to, once put on said plate, activate said actuator module through the valve block to adjust it in the required position according to each workpiece. The tool for clamping the workpiece is also actuated through the valve block. In this way, a flexible system is obtained, which can be easily adapted to the requirements of the workpiece and wherein human intervention is completely eliminated.
Abstract:
Die Erfindung betrifft eine Anordnung zur Positionierung und Positionserfassung einer verformbaren Lasttragplatte, aufweisend eine Antriebs-Parallelkinematik mit einer Mehrzahl von Antriebs-Beinen, wobei die Lasttragplatte einen Bestandteil der Antriebs-Parallelkinematik bildet oder starr auf einer Plattform derselben fixiert ist, eine Referenz-Parallelkinematik mit einer durch deren Plattform gebildeten oder auf dieser starr fixierten, im Wesentlichen verformungsfreien Referenzplatte, die unterhalb der Lasttragplatte positioniert ist, und einer Mehrzahl von Referenz-Beinen, eine Sensoranordnung, die eine Mehrzahl von in den Referenz-Beinen angeordneten Beinlängenmesseinrichtungen sowie eine Mehrzahl von auf der Referenzplatte angeordnete Abstandssensoren zur punkt- oder bereichsweisen Erfassung des Abstandes der Referenzplatte von der Lasttragplatte umfasst, und eine eingangsseitig mit den Beinlängenmesseinrichtungen und den Abstandssensoren verbundene Positionsberechnungseinheit, die die Ausgangssignale der Beinlängenmesseinrichtungen und Abstandssensoren zu einer Positions-Karte der Lasttragplatte verarbeitet.
Abstract:
The invention is directed at a positioning arm for positioning of a scan head of a surface scanning measurement device – such as a scanning probe microscopy device – relative to a surface. The positioning arm comprises a base at a first end thereof for mounting the arm with the base to a static reference structure. The positioning arm further comprises a first and a second arm member extending from the base, the second arm member extending parallel to the first arm member. The arm comprises a bridge member at a second end thereof, connecting the first and the second arm members. The first and the second arm member are respectively connected to each one of said base and said bridge member by means of a hingeable connection. The positioning arm further comprises an actuator for inducing a relative displacement between the first and the second arm member in a longitudinal direction of said first and second arm member for swinging the second end of the positioning arm in a direction transverse to the lateral displacement. The bridge member comprises a support for supporting the scan head.
Abstract:
The present invention concerns a mobile table (1) having : At least one mobile support plane (6) in a direction (X) and/or (Y); An upper plane (4) overlapped to the support plane (6) and mobile in a vertical direction (Z) of lifting/lowering in respect to said support plane (6); First actuating means (10, 15, 20, 25) to generate the movement in the direction (Z) of the upper plane (4) and comprising at least one fixed actuating element and one stem (10', 15', 20', 25') associated with said fixed and mobile actuating element according to an extraction/retraction motion from/into the fixed actuating element in such a way as to cause the relative lifting/lowering of the upper plane (4). In accordance with the invention, at least said fixed actuating element results to be arranged under the support plane (6), preferably under the surface (6A) delimiting superiorly the support plane (6) which is provided with a hole for the passage of the stem.
Abstract:
A method for aligning and positioning a module mounted on a vehicle is provided in accordance with the present invention. Modules requiring azimuth and elevation position accuracy need to be aligned to be relatively horizontal (true to earth) for efficient operation. The method in accordance with this invention achieves this by providing an adaptor, typically a substantially flat plate element, on a vehicle frame for mounting the module. The vehicle frame is first aligned true to earth using a screw jack and an electronic sensor is calibrated with reference to the vehicle frame. Then the adaptor is aligned such that it is also true to earth. The module is fitted and locked on the leveled adapted plate. Hydraulic jacks are provided to adjust the vehicle frame and accordingly the adaptor to align true to earth irrespective of the type of terrain the vehicle is located on.
