Present invention relates to a rotary positioner that allows a welding table's work surface to be set at an angle as desired by a user. Two vertical frames can move and slide along the length of a chassis-bar to adjust the distance between the two vertical frames. As long as the length of a welding table does not exceed the total greatest distance between the two vertical frames, the present invention can fit any work table or welding table. Caster wheels and height adjustment knobs allow for easy movement and balancing of the rotary positioner.

A machining center includes two independent carriages that are supported so that they can slide along respective longitudinal translation axes by a pair of parallel horizontal rails which are extended along a longitudinal direction and are fixed in a raised position to a supporting structure. Each one of the carriages supports a machining head which can move along a transverse translation axis and along a vertical translation axis by guiding components. Each of the machining heads supports a tool holding spindle so that it can rotate about a horizontal rotation axis by rotary support components. A workpiece holding table is supported at a base of the supporting structure so that it can rotate about a first rotation axis which is extended in a horizontal and longitudinal direction. Two mechanized tool magazines at the opposite longitudinal ends of the supporting structure are accessible by the spindles.

A second sub fixture being able to freely rotate with the rotary head plate when rotated. A tailstock plate mounted to the second sub fixture. The tailstock plate having a first precision surface and a second precision surface, A first head plate attached to the first precision surface of the rotary head plate and the first precision surface of the tailstock plate. A second head plate attached to the second precision surface of the rotary head plate and the second precision surface of the tailstock plate. The first head plate and second head plate adapted to each receive two cylinder heads. The first head plate and second head plate each including at least one cylinder head opening.

The disclosure relates to a machining system for aircraft structural components, comprising a first frame for mounting a workpiece, and a second frame for mounting a tool pair including an upper tool and a lower tool cooperating therewith. The workpiece is positioned between the upper tool and the lower tool. The second frame is formed to be displaceable at least in a longitudinal direction with respect to a base. The tool pair is held in the second frame such that it is displaceable in a transverse direction which is at an angle to the longitudinal direction. The second frame is held on at least one swivel bearing so that the second frame can be adjustably swiveled together with the tool pair about a swivel axis.

A horizontal five-axis turning plate type machining center includes a support base, a lathe bed arranged on the support base and a column arranged on the support base, wherein the lathe bed and the column are fixedly connected through a connecting arm, a turning plate device is arranged on the support base, an X-direction sliding plate capable of sliding in an X direction on the lathe bed is arranged on a side, facing the column, of the lathe bed, and a third driving unit capable of driving a workbench to perform position conversion between a turning plate and the X-direction sliding plate is arranged on the turning plate.

The present application discloses a flexible clamping device. A sleeve is fixed on a base, an adjusting shaft is connected with a mandrel and the sleeve respectively, the mandrel is fixed on the upper end face of the adjusting shaft, and the bottom outer wall of the adjusting shaft is in small clearance fit with the inner wall of the sleeve; a lock screw is installed on the upper right side wall of the sleeve, a pinion is installed on the upper left side wall of the sleeve via a rotating shaft, saw teeth are provided on the side wall of a floating shaft, and the pinion can be engaged with the side teeth of the floating shaft.

A workpiece change for use in a machine tool that comprises a tool spindle for clamping tools for machining workpieces, comprises two wheels arranged parallel to one another and rotatable about an axis of rotation into at least two prominent angular positions. Two swivel tables for clamping workpieces are arranged between the wheels and are each mounted on the wheels to swivel about a swivel axis which runs parallel to the axis of rotation. In each prominent angular position, one of the swivel tables is located in its working position in which clamped workpieces can be machined with the tools. Both wheels are supported at their rim.

Disclosed herein is a tool-inclining system, which is characterized in that it is provided with a structure that is simple, compact, and able to operate according to an altogether reliable mode of operation. The system comprises: a base for securing said system to a structure that is to carry said tool, such as a robot arm; a support on which said tool is to be fixed, said support being configured in such a way that said tool fixed to said support defines a working axis (S); a connection member for connection of said support to said base, said member allowing a given angular movement of said support so that said working axis displaces, starting from a neutral position, according to a tilting movement; and fluid countering means or elastic countering means, which act on said support so as to exert an action that counters said tilting movement.

A workpiece positioner is includes a main positioner body including first and second end plate members. The main positioner body also includes a pair of tubular structural members extending between and interconnecting the end plate members, a number of substantially co-planar panel sections disposed between the first and second end plate members, and a number of spaced-apart reinforcing ribs interspersed between the panel sections, the reinforcing ribs also disposed between and interconnecting the tubular structural members. Each of the reinforcing ribs has two opposite side edges, each formed with an arcuate outline shape. The workpiece positioner may also include two or four workpiece support arms attached to the main positioner body, where each of the support arms may have a workpiece-supporting turntable mounted thereon, and may further include first and second shield members attached to the respective tubular members. A method of operating a workpiece processing machine is also described.

A work positioner includes a first work retaining portion for retaining a first workpiece, a first drive portion for outputting a first rotational force about a first rotation axis and imparting a first angular movement about the first rotation axis to the first work retaining portion, a bearing portion supporting the first work retaining portion in cooperation with the first drive portion, a base arranged away from the first rotation axis, a first support column extending along a first support axis extending from the base toward the first rotation axis and supporting the first drive portion, and a second support column extending along a second support axis extending between the base and the first rotation axis so as to be parallel to the first support axis and supporting the bearing portion. The first support column includes a plurality of first support column pieces arranged along the first support axis.
