The invention relates to a device for tensioning a canvas on a frame, which is for assembling two bars the ends of which comprise a groove. The device comprises: an optional sheath intended to be immobilized in a groove; a spacer comprising a central portion from which extend two lateral portions each having a bearing face coming to abut against the bottom of the sheath; a tensioner comprising a central portion from which extend securing means for securing the tensioner to the bars, via the sheath; a connecting member for connecting the spacer to the tensioner, and means for bringing the spacer closer to the tensioner, wherein the spacer being brought closer to the tensioner will cause each bar to translate along its longitudinal axis so as to space the bars apart from each other while keeping them perpendicular to each other.

A jig apparatus and associated systems and methods for forming a composite wing skin is presented, including providing a frame with a working surface. A plurality of indexing blocks are coupled to the working surface of the frame. Each of the plurality of indexing blocks has a first indexing surface oriented perpendicular to the working surface of the frame and a second indexing surface oriented approximately parallel to the working surface of the frame. A plurality of clamping blocks are also each moveably coupled to one of the plurality of indexing blocks. Each of the plurality of clamping blocks has a clamping surface oriented perpendicular to the working surface of the frame and in facing relation to the first indexing surface of an adjacent indexing block thereby defining a plurality of channels.

A workpiece clamping device able to clamp a first workpiece and a second workpiece placed on the first workpiece. The workpiece clamping device includes a receiving base on which the first workpiece is to be placed, a first clamping mechanism for clamping the first workpiece, and a second clamping mechanism for clamping a second workpiece placed on the first workpiece. The first clamping mechanism has a first clamp section and a second clamp section, which are provided on the receiving base so as to open and close. The second clamping mechanism has a third clamp section and a fourth clamp section, which are provided on the receiving base so as to open and close, to retain the second workpiece at a predetermined position with respect to the first workpiece.

A driving chamber (11) where pressurized fluid is supplied and discharged is arranged above a piston (10) inserted into a housing (1) ascendably and descendably. An ascent-detecting detection valve (32) is oriented laterally in an upper portion of the housing (1). An operating portion (10b) is provided on an upper portion of the piston (10), and an operated portion (79) movable in response to movement of the operating portion (10b) is provided on the detection valve (32). A transmission ball (70) is inserted into a transmission chamber (67) communicatively connected to an upper portion of the driving chamber (11). The transmission ball (70) converts ascent movement of the operating portion (10b) to lateral movement of the operated portion (79). Pressurized air for detection is supplied to an inlet (32a) of the detection valve (32) through a supply passage (B2).

An apparatus for aligning sections of pipe includes a first clamp member and a second clamp member coupled with the first clamp member. The first and second clamp members each include a first clamp jaw and a second clamp jaw longitudinally spaced from the first clamp jaw. Each one of a first plurality of turnbuckle assemblies is coupled with each one of the first and second clamp jaws of the first clamp member, and each one of a second plurality of turnbuckle assemblies is coupled with each one of the first and second clamp jaws of the second clamp member. An assembly made from a kit of components is also disclosed. The kit includes an apparatus for aligning sections of pipe, and a plurality of shoe inserts. The assembly includes the apparatus and at least two of the shoe inserts coupled with the apparatus.

A clamp assembly that may be used for securing to a raised portion of a surface. The clamp assembly comprising a mounting body of a general block shape having a slot for receiving the raised portion formed in a bottom surface of the mounting body attaching the clamp assembly thereto. The clamp assembly is configured with one or more pins that may be formed in a substantially elongated cylindrical shape. The pins may be configured to be received in one or more push-pin holes formed in the mounting body, whereby the push-pin holes extend to the slot from a side surface of push-pin holes. The clamp assembly includes a fastening element adapted to be received in a fastener hole formed adjacent the push-pin holes in the side surface of the mounting body. The fastening element is configured to secure, attach and hold the clamp assembly to the standing seam by forcing the pins against the raised portion of the surface disposed in the slot.

A clamping tool is provided which includes a base, a clamping arm articulated to the base for pivotal movement about a first pivot axis, a handle articulated to the clamping arm or base for pivotal movement about a second pivot axis, a bridge element articulated to the handle or the clamping arm for pivotal movement about a third pivot axis, a first wedge element having a first wedge surface, and a second wedge element having a second wedge surface facing towards the first wedge surface. In a first positional range of the handle, the wedge surfaces are spaced apart. In a second positional range of the handle, the second wedge surface is supported on the first wedge surface, displacement of the first wedge element driving a displacement of the second wedge element. The bridge element is articulated to the first wedge element for pivotal movement about a fourth pivot axis.

A single mounting device is provided for each trolley riser for use with a set of shims in order to accurately align and secure a clamp to a datum. In another aspect, a generally polyhedron-shaped clamp body is used with a mounting plate to secure a clamp in different orientations relative to a manufacturing plant locator.

An adaptable assembly line work-piece processor for use at a work station includes, but is not limited to, a work-piece supporter. The adaptable assembly line work-piece processor further includes, but is not limited to, a reconfigurable interface assembly attached to the work-piece supporter. The adaptable assembly line work-piece processor still further includes, but is not limited to, a work-piece manipulator attached to the reconfigurable interface assembly. The work-piece supporter, the reconfigurable interface assembly, and the work-piece manipulator are configured to cooperate to sequentially support and manipulate a plurality of differently configured work-pieces.

A connection element is provided for connecting at least two components. The connection element has at least two spherical, sphere-shaped or sphere-type or sphere-like sections, wherein a first section of the at least two sections is provided for the connection with a first component, and the second section of the at least two sections is provided for the connection with a second component.
