A method for positioning a rotary part on a machining fixture adapted to hold the rotary part for a machining operation is described. The machining fixture has a center axis and a diaphragm with engaging segments affixed thereto and extending away therefrom. The method includes mounting the rotary part on the machining fixture concentrically about the center axis and adjacent to the engaging segments, and then applying an axial force in a direction substantially parallel to the center axis against the diaphragm. This elastically deforms the diaphragm and radially displaces the contact members of the engaging segments into frictional engagement with a circumferential surface of the rotary part.

A centering clamping apparatus has a housing (1) with a centering element (2) mounted to be displaceable along a longitudinal axis between an open position and a clamping position. A finger element (3), mounted with centering element (2), is displaceable transversely to the longitudinal axis between a retracted position and an extended position. The finger element (3) is operatively connected to an adjusting member (4). The adjusting element (4) is mounted to be displaceable in the centering element (2). A blocking device (5) is provided on the centering element (2). The blocking device (5) either precludes a relative movement between the housing (1) and the centering element (2), with the finger element (3) fully retracted, or precludes a relative movement between the centering element (2) and the adjusting member (4), with the finger element (3) fully extended.

A positioning device to position, during in vehicle construction, a vehicle body component having at least one locating bore. The positioning device includes a locating pin having a conical end designed to be guided axially through a locating bore of the vehicle body component to centre and position the vehicle body component. The locating pin is mounted in a radially floating manner.

A machining system comprises a machine tool, a machine tool controller that controls the machine tool, an auxiliary device that assists the machine tool, and an auxiliary device controller that controls the auxiliary device. The machine tool and the auxiliary device work cooperatively for machining. The machining system comprises a signal management unit that receives a first signal and a second signal. The first signal indicates information about the machine tool as a criterion used for determining whether the machine tool and the auxiliary device are operable or inoperable. The second signal indicates information about the auxiliary device as a criterion used for determining whether the machine tool and the auxiliary device are operable or inoperable. The signal management unit outputs a third signal indicating an operable state or an inoperable state of the machine tool and the auxiliary device to the machine tool controller and the auxiliary device controller based on the first signal and the second signal.

A workpiece carrier consisting of a table adapter and a workpiece carrier base. The table adapter of the workpiece carrier is detachably mounted on a table of a measuring device or a machine tool. At least three different support points are arranged between the table adapter and the workpiece carrier base. A first support point comprises one rotary body and three balls. A second support point comprises a rotary body and two balls. A third support point comprises two contact elements. The table adapter and the workpiece carrier base can be clamped against each other after mutual positioning by means of a clamping system.

The present application provides a material transferring and positioning device for a wheel machining center, which includes a base plate, a base, a first bearing, a first shaft sleeve, a hydraulic cylinder brake, a rotary cylinder, a cap and so on. The application may meet the positioning requirement of the wheel machining center, and has the advantages of simple structure, convenient manufacture, stable performance, high positioning precision and simple operation, so that it is very suitable for automatic mass production.

A method of correcting an axial position of a workpiece support (1) used 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 form fitting manner.

A motorized hardware jig that allows for the changing and setting of drill guides in a matter of seconds without the need for any tools. The motorized jig receives a height for the panel on the face of a drawer and a center-to-center measurement for the hardware. The motorized jig automatically moves the drill guides to the desired position for drilling holes for the hardware.

The present invention relates to an alignment device (100) for adjusting a workpiece (400) on a machine table (300) of a numerically controlled machine tool (1000), the alignment device (100) comprises: a lower plate (20) which can be mounted on the machine table (300) of the machine tool (1000), an upper plate (10) which is movably arranged on the lower plate (20), on the upper side of which a workpiece carrier (200) can be mounted, an adjusting mechanism which is arranged between the lower plate (20) and the upper plate (10) for adjusting the relative position of the upper plate (10) to the lower plate (20), and a locking mechanism for securing the relative position of the upper plate (10) to the lower plate (20).

A centering mechanism for retaining an object, wherein the centering mechanism has a locking mechanism, having at least a first tangential surface. Furthermore, the centering mechanism can be used in conjunction with a mechanism for retaining an electronic device or an electronic device in a case. The structure of the centering mechanism and the locking mechanism allows for the locking mechanism to further actuate and lock the centering mechanism, such that an object retained therein is secured and aligned.
