Abstract:
Die Erfindung betrifft eine Oberflächenbearbeitungsvorrichtung mit einem Substratträger zur Aufnahme eines zu bearbeitenden Substrats, einer gegenüber dem Substratträger entlang einer ersten und einer zweiten Bewegungsachse verstellbaren Bearbeitungseinheit, einer Lageerfassungseinheit zur Ermittlung der Ausrichtung des Substrats und einer Steuerungseinheit zur Bewegungssteuerung der Bearbeitungseinheit in Abhängigkeit von der Ausrichtung des Substrats auf dem Substratträger. Um eine Oberflächenbearbeitungsvorrichtung bereitzustellen, welche sich kompakt herstellen lässt und in kostengünstiger weise eine genaue Oberflächenbearbeitung der zu bearbeitenden Substrate unabhängig von der Lage der Substrate auf dem Substratträger ermöglicht, ist vorgesehen, dass die Bearbeitungseinheit relativ gegenüber dem Substratträger, insbesondere um eine sich senkrecht zur durch die erste und zweite Bewegungsachse gebildeten Ebene erstreckenden Hochachse, verschwenkbar ist.
Abstract:
A power feeder (10) comprises a flexible strip (12) having a conducting front side (12a) and an insulating back (12b); a retainer unit (20) for holding the strip wrapped on a bar (18) with the back being in close contact with the bar; a feeder unit (22) connected electrically with the front side of the strip; and a base (26) mounted detachably on the headstock (24) of an automatic lathe. A tool-positioning device (14) including this power feeder comprises a driving unit (60) for bringing a tool (56) to be positioned into contact with a front side of the strip; a section (62) for detecting the conduction between the tool and the front side of the strip through the feeder unit to determine the position of contact with the tool; and a corrective processing section (64) for determining the position of the center line (18a) of the bar based on the position of the determined position of contact with the tool and properly correcting the machining position data preset for the tool in accordance with the determined position of the center line. The tool will not directly touch the bar, so that the surface of the bar and the tool itself are protected from damage.
Abstract:
A modular two-part welding and processing platform is described. A cart section is capable of rotating around objects such as pipes and cylinders, or of linear travel along plates or the like. This cart section reversibly couples to a processing section supplied for instance with welding apparatus, painting apparatus, cleaning means, analysis means or the like. By means of this two-part device, work pieces can be cleaned, welded, and inspected quickly and accurately. Special marks may be provided on the work piece which in conjunction with sensors and motoring means on the cart, allow for precise positioning of the process head with respect to the work.

Abstract:
Apparatus for aligning a plate in a desired plane of a machine comprises a plate (44) rotatable about at least one axis (42), mountable on a first machine part (40), a location device (48) mountable on a second machine part (47), wherein the location device on the second machine part may be brought into register with the plate in at least one location (57, 46) such that the plate rotates about the at least one axis until it is aligned with the plane defined by the at least one location of register between the location device and the plate. The plate may be rotatable about one or two axes. The plate may be provided with a scale (16) and a readhead (18) may be mounted on the second machine part. A docking station (20) may be provided to align the readhead with the scale whilst it is being connected to the second (20) part of the machine.
Abstract:
In a method of measuring an edge of a workpiece by scanning, scanning is performed by a scanning tool mounted on a moving head of an edge-facing machine while that moving head is moved along the edge to be measured before, during or after an edge- facing tool of the edge-facing machine faces that edge. The method may be performed by an edge-facing machine that comprises at least one edge-facing tool and that further comprises a scanning tool mounted on a movable head of the machine, which head is movable along an edge of a workpiece.
Abstract:
Ce dispositif de réglage de la position d'outils de coupe (5) ou en bout (6) par rapport à l'axe central (1) du canon de guidage (2) d'un tour automatique est constitué essentiellement d'une camera CCD miniature (3) équipée d'un tube d'extension (4) contenant une lentille à gradient d'indice (9) et d'une lentille achromate (10). Le tube d'extension (4) est introduit dans le canon de guidage (2) où il est maintenu par la pince de la poupée (28) qui enserre un embout de fixation (27) fixé lui-même au boîtier (18) qui enferme la camera. Une fois introduit dans le canon de guidage, cet ensemble permet d'obtenir l'image de l'outil par l'ouverture du canon de guidage. L'outil dont la position doit être réglée est éclairé par un jeu ce diodes électroluminescentes (16). L'image est transmise à un ordinateur par un câble (8). Le programme de l'ordinateur permet de créer sur l'écran une mire sous forme de coordonnées cartésiennes centrées sur l'axe (1) du canon de guidage, d'acquérir la position de l'outil dans ce système de coordonnées et de la comparer à sa position dans le système de la machine, puis de régler la position de l'outil en tenant compte des différences entre les coordonnées des deux systèmes.
Abstract:
A positioning device (10) for positioning the point of a cutting tool with respect to the axis of a workpiece bar comprises a spherical material (16) with an electrically conducting surface area (16a); an abutment mechanism (22) that brings the spherical material (16) into contact with the inner edge (20a) of an opening (20) in an end of a holder (18) for holding a workpiece bar to hold a part of it coaxially in the opening (20); a drive mechanism (32) for bringing the cutting tool (28) into contact with the electrically conducting surface area of a spherical material; an electrical unit (24) for supplying current between the cutting tool and the conducting surface area of the spherical material when they are in contact; a detector (34) for detecting a conducting state between the cutting tool and the conducting surface area of the spherical material by means of the electrical unit to determine the contact position of the cutting tool; and a processor (36) that determines the position of the center (16c) of the spherical material based on the contact position of the cutting tool and corrects predetermined tool position data properly depending on the determined center position.
