A universal jig is provided for clamping wind turbine blades. The jig has a rectangle-like shape forming a space for clamping a blade at the blade root or the blade body. The jig comprises a set of vertically-moving parts; a set of horizontally-moving parts; a plurality of adjusted pads; and a plurality of positioning parts. The vertically-moving parts comprise two upper connecting posts and two lower connecting posts sheathed with each other separately to form two length sides of the jig. The horizontally-moving parts comprise two left connecting posts and two right connecting posts. The adjusted pads are locked on the left and the right connecting posts. The positioning parts are locked at the upper and the lower connecting posts of the length sides of the jig and are locked at the left and the right connecting posts of the width sides of the jig.

A system for supporting workpieces comprises a base and a plurality of support members (1), each support member (1) comprising a plate (11) and means for positioning the plate (11) in relation to the base. In at least some of the support members (1). The means for positioning the plate (11) comprise at least three controllably extendable members (13) arranged for determining the position and inclination of the plate (11) in relation to the base, thereby allowing for controlled positioning of the plate (11) in relation to the base and for controlled inclination of the plate (11).

The present invention relates to a clamping device (10) and a method for clamping a workpiece (2), preferably to a machining device, in particular for clamping a workpiece (2) having one or more curved surfaces or free-form surfaces, comprising: a first receiving section (12) for receiving a workpiece (2), which preferably has at least in sections thereof a first negative form relative to the workpiece (2) to be received, a second receiving section (13) for receiving the workpiece (2), which preferably has at least in sections thereof a second negative form relative to the workpiece (2) to be received, wherein one of the receiving sections (12, 13) can be moved out of a first position relative to the other receiving section (12, 13) into a second position, and one or more clamping mechanisms (20a, 20b) is/are provided on the first receiving section (12) and/or on the second receiving section (13).

A vehicle body part rack, being used for placing a vehicle body part during assembly or post-treatment of said vehicle body part, including a base plate and a plurality of vehicle body part supports arranged on the base plate, each of the vehicle body part support comprising a supporting head, and a supporting rod connected to the supporting head and the base plate, the supporting rod being movable with respect to the base plate, characterized in that the rack has lateral supports able to hold the vehicle body part and to rotate it.

A machining system includes: a robot; a control unit that controls the robot according to an operation program; a workpiece supply part to which a workpiece is supplied; a detection unit that detects the position of the supplied workpiece; a position correcting unit that corrects take-out position information in the operation program, according to the detected position; and a machining device that machines the workpiece taken out from the workpiece supply part. The workpiece supply part includes a fixing jig detachably holding the workpiece between a pair of holding surfaces. The fixing jig includes, in at least one of the holding surfaces, a number of pins that are arrayed parallel to each other to be individually movable in axial directions thereof and that can be fixed at arbitrary positions in the axial directions to conform to the surface shape of the workpiece with which distal ends thereof are in contact.

A system for supporting a workpiece is disclosed, wherein several heads with a suction cup define an engaging and supporting surface that is at least partially shaped like the workpiece. Each head with suction cup is coupled by a ball joint with a first movable element of a vertical linear actuator and is couplable by a removable fitting with a fork carried by a second movable element that rotates around a rotation axis that is coaxial with the axis of the linear actuator. The second movable element carries an abutment, spaced from the center of the ball joint against which the suction cup head abuts and moved by the linear actuator to perform the adjustment of the orientation thereof around the ball joint.

A system for supporting workpieces during machining. The system comprises one or more adjustable workpiece support assemblies and a robotic unit. Each workpiece support assembly comprises a pedestal and a rotatable fixture element. The robotic assembly comprises means of mobilizing and immobilizing each support assembly, so that the fixture element may be secured in a particular orientation. The robotic unit moves along a frame, and manipulates and fixes the position of the fixture elements to match the contour of a workpiece. Vacuum forces may be applied through the workpiece support assemblies to secure the workpiece against the fixture elements.

A device for stabilizing a workpiece, in particular a thin-walled workpiece mounted in a machine tool, comprises at least one base; and a plurality of stabilizing elements. The stabilizing elements protrude away from one surface of the base, wherein the stabilizing element comprises a cylinder and a rod arranged therein and the rod can be driven hydraulically to move in the axial direction of the stabilizing element such that the rod of at least two of the stabilizing elements can be brought into contact with one surface of the workpiece.

A method and apparatus for maintaining a selected configuration for a structure. Metrology data for a support system is received while the support system holds the structure. A determination is made as to whether a current configuration of the structure is within selected tolerances of the selected configuration for the structure based on the metrology data. The support system is moved to move the structure held by the support system into the selected configuration in response to a determination that the current configuration of the structure is not within the selected tolerances of the selected configuration for the structure.

A jig device includes an upper end configured to support an object, and a lower end comprising a hole for insertion and coupling of the upper end in an upper portion and an air inlet and an opening and closing portion configured to open and close the air inlet, in a lower portion. A position of the upper end is configured to be fixed at a point in time at which the air inlet is closed due to air pressure that occurs inside the lower end in response to closing the air inlet.
