A dowel basket assembly apparatus includes a jig table rotationally supported on a bearing assembly, which supports a table top assembly having arms extending radially outwardly and supporting first, second and third jig table bases. The bases move through first, second and third stations by rotating the assembly. First jig table is positioned at first station, second jig table at second station, and third jig table at third station. Rods are located in receptacles on first jig table base at first station. Simultaneously, rods are welded to form a dowel basket on second jig table base at second station. Simultaneously, a welded dowel basket is unloaded from third jig table base at third station. After completion of the steps of locating, welding and retrieving, the apparatus is rotated to advance the jig tables to the next station.

A chuck table holding a frame unit including a workpiece is securely placed in an opening of an annular frame by a tape. A transparent holder having a holding surface holds the workpiece with the tape interposed therebetween. A frame body is erected around and surrounding the holder, the frame body having a plurality of suction holes that are open in an inner circumferential surface of the frame body. The frame body has an inside diameter equal to or smaller than an inside diameter of the annular frame. While an opening of the frame body is being covered by the tape, a suction force is transmitted through the suction holes into the frame body, discharging air from between the tape and the holding surface to bring the tape into intimate contact with the holding surface thereby securing the workpiece of the frame unit to the holding surface.

A hydraulic pressure vessel long seam welding jig device having a triangular frame, a pair of hydraulically actuated clamp mechanisms each having a clamp activating hydraulic cylinder operatively associated therewith, whereby each of said clamp mechanisms are positioned on opposite ends of said carriage beam and arranged to hold a workpiece during a long seam welding operation.

Present invention teaches a height adjustable rest having four main parts: a base, a cylindrical knob, a cylindrical post and a snap ring. The cylindrical post has a vertical straight groove to guide the up-and-down height adjustment when the knob is turned relative to the base. The base holes and the knob holes, along with the corresponding rods, provide increased torque when larger and/or heavier workpiece is being supported. The matching inner thread portion (on the inside of the cylindrical knob) and the outer thread portion (on the outside of the base) is a desired feature to make the product less susceptible to damages or work debris compared to other products with exposed threads.

A cutting device capable of efficiently cutting an object with a simple configuration includes a grasp unit including a first grasper and a second grasper movable in an opening and closing directions to grasp the object, a cutting unit disposed side by side with the first and second graspers and moved in a cutting direction along the opening and closing directions to cut the object, and a position setter setting a cutting start position and a cutting end position based on respective positions of the first and second graspers that are grasping the object, respectively.

Provided is a fabrication square for aligning workpieces. The square includes a triangular shaped base, a first arm, a second arm, and a relief cut where the arms intersect the base. The arms extend away from the base at a 90-degree angle. The base and first arm further include a series of holes that match the hole pattern found on a conventional metal fixture table, while the second arm includes a slot to allow for rotation. The square can be aligned with and attached to the fixture table with one or more fixture stops that secures the square to the table via the holes. The use of the square, fixture stops, and table lock the workpieces in position, which in turn prevents movement before, during, and after welding, thereby increasing fabrication precision.

A method of assembling a plurality of subcomponents to form a finished component comprises gripping a first subcomponent with a first end-of-arm tool, wherein the first end-of-arm tool is attached to a first robot arm and grasping a second subcomponent with a second end-of-arm tool, wherein the second end-of-arm tool is attached to a second robot arm. Moving the first and second end-of-arm tools to position the first subcomponent relative to the second subcomponent in a pre-assembly position and then moving the first and second end-of-arm tools to engage interface surfaces of the first and second subcomponents. Forming a joint between the first subcomponent and the second subcomponent with a joining tool attached to a joining robot arm to thereby assemble the finished component.

A T-slot mounting and alignment system for non-rigidly mounting a workpiece or fixture to a work-piece positioner table, welding positioner table or machine tool table having one of more T-slots includes a T-dog, a dog nut, at least one bolt, and at least one fastener. The at least one fastener fastens the T-dog to the workpiece or fixture, and a dog stem of the T-dog extends through a guide slot in the workpiece or fixture and into the T-slot in the table. The dog nut mates with the at least one bolt and tightens to engage a distal end of the dog stem, wherein clearance is provided in the assembled structures to prevent the workpiece or fixture from being tightly clamped against the table. Consequently, compensation for misalignments is possible during setup.

Features relating to a laser etching and/or tag writing machine are provided. The machine may include a tray assembly including a tray and a nest. The tray may hold an array of vaporizer cartridges. The tray may allow for a laser-etching operation to be performed by the machine on at least one or two sides of the vaporizer cartridges held by the tray. The tray may allow for the array of vaporizer cartridges to be rotated at the same time between laser etching operations. The tray may additionally and/or alternatively allow for the machine, such as via an antenna, to write data to an NFC tag of a corresponding vaporizer cartridge before, during, and/or after each laser etching operation.

An angle element for a welding and clamping table system includes an L-shaped profile, a base plate releasably fastened at one end of the L-shaped profile and provided with a system borehole of the welding and clamping table system, and a member releasably fastened at another end of the L-shaped profile and selected from the group consisting of a further such base plate and a clamping plate which is provided with several threaded boreholes to accommodate various hole patterns of quick-change clamps.
