An auto-positioning hydraulic pneumatic fixture contains a base, at least one locking device, multiple pistons, multiple positioning modules, and multiple platforms. The base includes at least one installation zone for fixing at least one locking device. A respective one locking device includes a fixing module and a clamping module. The fixing module has a body, a connection segment, and an affix portion. The clamping module includes a positioning bolt and a pair of clamp units, and each clamp unit has a clamping face. The affix portion has a defining groove and a linear slot. The body has at least one tilted rail, and a respective one positioning module has a mounting unit and at least one locating unit. The mounting unit has two oblique faces and multiple fringes, and s respective one platform is configured to fix the respective one workpiece.

A portable press configured to selectably apply either compression or expansion forces to objects or workpieces, thereby permitting multiple functions such as pressing, bending, fixturing, spreading, lifting, and position holding assistance in fabrication applications to the objects or workpieces.

An air chuck includes: a finger support part including a pair of fingers; a chuck main body part including an operation mechanism operable to open and close the pair of fingers; and linking mechanisms that detachably link the finger support part to the chuck main body part. The linking mechanisms each include: a linking shaft that extends from the finger support part; a shaft insertion hole formed in a body of the chuck main body part; a catch body that becomes elastically caught on a catch surface of the linking shaft when the linking shaft is inserted into the shaft insertion hole; and a delinking member that is manually operated so as to release the catch body caught on the catch surface when the finger support part is detached from the chuck main body part.

A support system (1) for a horological component (9), in particular for a horological component comprising a surface (91) generated by revolution and/or an axis (A9), includes a positioning device (2), in particular a centering device, for the horological component (9) in relation to an axis (A) of the system, and a holding device (3) for the horological component (9), the positioning device and holding device being independent and/or different and/or distinct.

An adjustable bar-guiding device includes at least one pair of complementarily-shaped jaws which are slideably associated with a fixed frame with the interposition of at least one movement lever mechanism which is actuated by at least one fluid cylinder. The jaws perform a translational motion according to a stroke of mutual approach/spacing apart, between a first configuration of substantial juxtaposition of their respective surfaces and a second configuration in which the surfaces are located at a predefined distance for containing a bar.

A chuck mechanism operates a piston in a cylinder tube by using action of compressed air and opens and closes, by using a rod coupled to the piston, a pair of fingers, thereby gripping work W. The locking mechanism locks the fingers at work grip positions. The locking mechanism includes a first locking member, a second locking member, and a drive device. The first locking member is displaced when the pair of fingers are opened or closed. The second locking member retains the first locking member so as to lock the fingers at the work grip positions. The drive device relatively displaces the first locking member and the second locking member to locking positions and non-locking positions.

The present invention relates to a clamping device having a mounting element with an axis of rotation X, an actuator, a support that has an opening of axis X in which opening the mounting element and the actuator are positioned. The mounting element includes a slide in which there are positioned a ring and a locking wedge which collaborate with at least one angle transmission. The support has an interior groove arranged in the opening and the ring and the locking wedge collaborate with the interior groove. The mounting element can thus easily be angularly positioned. There are preferably two angle transmissions positioned such that they are diametrically opposed.

A locating pin assembly including a locating pin movable between extended and retracted positions. The locating pin includes a locating pin top having a top end and a bottom end, a locating pin base receiving the bottom end of the locating pin top, and a dowel pin configured to couple the locating pin top and locating pin base together. The locating pin assembly also includes a drive rod moveable relative to the locating pin. The drive rod includes a drive rod top having a top end and a bottom end, and a drive rod base partially housing the drive rod top. The locating pin assembly also includes a finger coupled to the drive rod and movable between extended and fully retracted positions, the finger is extended by the drive rod without movement of the locating pin, and the finger is rotatable from a first position to a second position.

An arrangement for working a tube end includes: an operating cylinder with a piston displaceable along an longitudinal axis; and a tube mounting, a tool holder being provided at an end of the piston facing the tube mounting. The operating cylinder is provided as a tandem cylinder. At least two cylinder stages are offset along the longitudinal axis. The piston includes connected piston segments, each piston segment being allocated to a cylinder stage.

A clamp device is provided with a detection section which detects the pivotal position of a clamp arm. The detection section has: a cam section which is provided on a pivot shaft, includes a predetermined cam surface, and is formed so that the radial distance from the center of the pivot shaft to the cam surface varies circumferentially; and a proximity sensor which detects the position of the cam surface which varies as the pivot shaft pivots.
