The invention relates to a centring arrangement for a component carrier, in particular for a mounting frame for structural aircraft components, having a centring pin, a centring receptacle for the centring pin, and a rotary drive for rotating the centring pin about a longitudinal axis of the centring pin, so that the centring pin can be brought into centring engagement with the centring receptacle as a result of the rotation. The invention further relates to a method for centring and locking a centring receptacle.

A positioning assembly for positioning a rotary part to be machined includes a machining fixture and a positioning device having an elastically-deformable diaphragm concentrically mounted to the fixture and defining an annular loading zone which receives an axial force substantially parallel with a center axis of the fixture. The positioning device has circumferentially-spaced engaging segments, fixed to the diaphragm and extending away therefrom, which have contact members that are displaced radially to frictionally engage the rotary part when the axial force is applied to the loading zone of the diaphragm.

The invention relates to a clamping fixture comprising a chuck (1) and for locking thereto a workpiece pallet (2). The chuck (1) comprises first centering members in the form of centering spigots (5) whilst said workpiece pallet (2) is provided with a main body (20) and secured thereto a centering disk (23). The centering disk (23) is provided with second centering members in the form of centering openings (24). The centering spigots (5) of the workpiece pallet (2) are adapted to the centering openings (24) of the workpiece pallet (2) that the latter is alignable in the X-direction and Y-direction on clamping to the chuck (1). Provided topping the chuck (1) is a sealing member assembly (7). Disposed between the centering disk (23) and the main body (20) of the workpiece pallet (2) is a sealing disk (21) which overhangs the centering disk (23) radially. The portion of the sealing disk (21) overhanging the centering disk (23) radially is configured such that said portion sealingly comes into contact with a sealing member of the sealing member assembly (7) when clamping the workpiece pallet (2).

Centering apparatuses and methods for precision placement of a product or component, such as a ceramic honeycomb body, prior to a post-production processing steps are provided. In particular, after extrusion of a component or ware, the component or ware oftentimes requires one or more post-production processing steps in order to obtain a final product. The centering apparatuses and methods described herein provide for the precise and accurate centering of the product (or component) prior to performing these post-production processing steps, thereby obtaining repeatable, consistent, high-quality final products.

A workpiece support (1) for removing material from a dental workpiece (2) which is held by the workpiece support (1) and is rotated together with the workpiece support (1) about a drive rotation axis (3) when material is being removed. The workpiece support (1) has at least two workpiece support parts (4, 5, 6) which can be separated from each other and connected to each other. One of the workpiece support parts (4, 5) has at least one compensation region (7) with a material projection (8) for introducing a compensation surface (9) by removing material, and the other workpiece support part (6) has a seating surface (10) for connecting to the compensation surface (9) in a formfitting manner.

The invention relates to a machine (1) for machining pipe ends. At least one centering device (8; 35) is associated to said machine, which centering device centers a tubular workpiece (5, 5) in relation to an axis of rotation (D) of the machine for machining pipe ends extending in the center of the machine, the tubular workpiece either being stationary in the case of a rotating tool head (4) or rotating in the case in which the tubular workpiece is fastened in the machine chuck (9). Precise centering of the tubular workpiece (5, 5) is quickly and simply achieved in that the centering device (8; 35) has a clamping housing (13; 130) that is open toward the axis of rotation (D), which clamping housing is designed comprising at least three means (14, 15, 16; 140, 150, 160) for contacting the tubular workpiece at the outer circumference and for clamping the tubular workpiece (5, 5) in a centered manner, which means are circumferentially distributed and adjust mechanically independently of each other to the particular diameter of the workpiece (5, 5) to be machined.

The centering apparatuses and methods described herein provide for the precise and accurate centering of the product (or component) prior to performing these post-production processing steps, thereby obtaining repeatable, consistent, high-quality final products.

A device for extracting drilling sludge for use at difficult to access locations on a building site includes a main body. The main body has a cavity on a lower side of the main body and a drilling sludge that is disposed in the cavity during a use of the device is extractable from the cavity by a suction device. The main body also has an extraction opening which opens into the cavity.

A system and method for rotation assembly centering is disclosed. The rotation assembly may be used in a substrate processing system for moving substrates between reaction chambers in the system and its centering is important for processing quality. This disclosure presents a substrate processing apparatus with a rotation arm centering function, comprising: a predetermined number of reaction chambers configured to process substrates; a rotation assembly disposed at a center of the reaction chambers; a chamber wall surrounding the reaction chambers; a transmitting unit disposed on the rotation plate, the transmitting unit configured to transmit signals to receivers; and a plurality of sensors disposed at designated places on the chamber wall, each of the sensors configured to receive a signal transmitted from the transmitting unit.
