A tooling base that is an improvement over current designs in the form of simplified number of parts and easier manufacturing of parts is described. The tooling base uses alignment fixtures on threaded rods that are restricted in their movement within the tooling base by stops. The stops are located either on the threaded shafts or on the alignment fixtures. This allowed degree of movement enables simplified part design and manufacture while maintaining the precision and accuracy of registration of a tooling fixture with the tooling base.

A device for compensating the offset in automatic locking systems for the mounting of blanks comprising a box-like body composed of a T-shaped hollow body and a U-shaped base, which form an inner seat for a frustum-shaped jacket, which is arranged coaxially to the shank of the hollow body and above a piston, which can move transversely to the shank, a traction element being slideably arrangeable in the shank of the hollow body, the traction element cooperating selectively with balls which can be accommodated within openings provided in the shank and within second seats provided on the jacket, elastically compressible elements being arranged between the head of the hollow body and the jacket.

A float type clamping mechanism is provided, comprising a workpiece pallet having a central post provided on its bottom surface and a chuck. The chuck can be releasably coupled to the central post. The chuck has a base, a top seat, a piston seat with spring members provided between the piston seat and the top seat, a movable socket having movable detents provided around its periphery, and a bottom cover. When the central post of the workpiece pallet is inserted into the movable socket, the movable detents displaced inward to detent the central post so as to allow the movable socket to float upward slightly, and the movable socket is pressed downward through simple mechanism to clamp the central post firmly so that zero clamping effect between the workpiece pallet and the chuck can be achieved.

A coupling device of jigs includes a foundation, a tube, a plurality of balls, and a piston base. The foundation has a chamber, in which a part of the tube is inserted. The tube has a plurality of through holes for housing the balls. The piston base is received in the chamber, and fitted to the tube. An inner surface of the piston base has a circular groove and an abutment surface. The piston base can be moved along an axial direction of the tube between a first position and a second position. When at the first position, a part of each ball is inside the circular groove; when at the second position, an area where the abutment surface abuts against each ball is not merely a single point. Whereby, the force applied on the abutment surface is dispersed, and therefore the processing accuracy of workpieces is ensured.

An automatic loading and unloading processing system includes a material storage assembly to store workpieces; a positioning device on a worktable; and a transport mechanism to transport the workpiece from the material storage assembly to the positioning device and transport the processed workpiece into the material storage assembly. The material storage assembly includes a material tray; fixing bases; a motion mechanism; and holders on the fixing base for fixing the workpiece, and the motion mechanism controls the movement of the material tray. The transport mechanism includes an auxiliary loading and unloading system arranged at a worktable to grab the holders and move horizontally; and a main loading and unloading system arranged on a main spindle to grab the holders and move vertically.

The invention refers to a chuck pallet (1.3) with solid groove-sidewalls (2.3) for clamping chucks (1.1), whereby the x-y-references (2.5) of the chuck pallet (1.3) are allocated in the same plane (2.1) as the z-references (2.1) and the x-y-references (2.5) are also allocated at the solid groove-sidewalls (2.3). The solid groove-sidewalls (2.3) have thereby a tapered profile.

An interface structure that is constituted by a first, U-shaped toothed pivot, which can be associated in an upper region, by way of a jaw connection, with a fixing element with the interposition of a first bush for centering. The first toothed pivot is rendered axially integral in a lower region with a fastening element that can be associated with an underlying device for compensating the misalignment in automatic locking systems for the mounting of blanks.

A machining fixture contains: a base, a plurality of positioning blocks, and a workpiece holder. The base includes a first connecting face on which plural fixing slots are arranged, and each fixing slot has a threaded hole. Each positioning block includes an affix portion and a fixation portion having two symmetrical contacting faces and two flexible portions. Each positioning block further includes a mounting hole or blind aperture defined on a middle section thereof and passing through the affix portion from the fixation portion. A screw bolt is screwed with the threaded hole of each fixing slot via the a mounting hole or blind aperture, and the affix portion of each positioning block enters into and contacts with each fixing slot of the base. The workpiece holder includes a second connecting face on which plural locating slots are arranged.

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).
