    Abstract: A portable workpiece stopping device, attachable to a work surface relative to a primary tool, permitting a repetitive same-length operation to be performed on any number of workpieces, and which allows for interruption of the operation without affecting the essential positioning of the stopping device relative to the primary tool. The stopping device comprises a base plate selectively attachable to a work surface, a rotation plate rotatably coupled to the base plate, an alignment plate adjustably coupled to the rotation plate, a stop plate fixedly coupled to the alignment plate, and a support shelf adjustably coupled to the stop plate. The stopping device can be selectively transitioned from an obstructing position, which blocks the end of a workpiece pressed against the stop plate, thereby allowing the repetitive same-length operation to be performed, to a non-obstructing position which provides for unfettered positioning of any workpiece relative to the primary tool.

  • Patent number: 8832921
    Abstract: A two-piece locking nut assembly for securing a mantle to a head assembly of a cone crusher. The two-piece locking nut assembly includes an inner nut and an outer nut. The inner nut includes a set of axial bores that each receive a jackscrew. Once the locking nut assembly is in position on the head assembly, the series of jackscrews are tightened to exert a force on the mantle that is counteracted by forces through the inner nut and into the head to create a locking force between the locking nut assembly and the head assembly. The outer nut is turned along the inner nut to hold the locking nut assembly in place. Once the outer nut is moved into position, the jackscrews are removed such that the outer nut continues to apply the locking force between the mantle and the head through the locking nut assembly.

  • Patent number: 8672103
    Abstract: A main shaft drive includes a supply groove that opens to a friction surface, that extends so as to surround a main shaft within a contact range where the friction surface and a pressing surface oppose each other, and that includes an intersecting groove and a discharge opening. The intersecting groove extends in a direction of intersection with a circumference in which a rotational center of the main shaft is a center. The discharge opening is connected to a location that is outside the contact range. By opening a nozzle hole, used for supplying lubricant, towards the supply groove, as the main shaft rotates, four intersecting grooves move relative to the contact range, so that the lubricant is supplied to the four moved intersecting grooves. Therefore, the lubricant easily reaches a location within the contact range where the friction surface and the pressing surface oppose each other.

  • Patent number: 8662485
    Abstract: A suction apparatus 1 holds a wafer W by performing vacuum-suctioning on the wafer W. The suction apparatus 1 comprises a suction substrate 2. The suction substrate 2, which is rigid, comprises a plurality of pin-like protrusions 2a formed so that the tip-end faces (upper surfaces) thereof are the same height. An elastic coating layer is coated by way of an undercoat layer 4 on the tip-end faces of the protrusions 2a. When the wafer W is suctioned, even if a foreign matter is interposed between the wafer W and the suction surface, because the foreign matter embeds itself into the coating layer 3, the planarization of the wafer W is improved. In addition, because the coating layer 3 can be made comparatively thinner, undulations in the wafer W can be reduced and, to that end, the planarization of the wafer W in the suctioned state can be improved.

    Abstract: A quick-action clamping cylinder is described which has a housing and a cover which covers the housing and has a center opening for receiving a retractable nipple that is arranged on the lower side of a workpiece pallet. The retractable nipple is locked in a spring-loaded manner in the housing by way of a plurality of locking balls that are spring-loaded in the locked position on the outer periphery of the retractable nipple. The locking balls are disengaged from the retractable nipple in the unlocked position by displacing a piston actuated by a pressurized medium. The disclosed examples provide a simple, small clamping system. To this end, the locking balls convert the spring force exerted by the springs into a multiple of the retraction force acting on the retractable nipple, by way of a lever arm transmission.

  • Patent number: 7866641
    Abstract: An adaptor and its method of use for cleaning the work piece chuck clamping surfaces of a turning center (lathe). An adaptor of the present invention includes a number of orifices that are arranged and oriented to direct pressurized fluid (e.g., air and/or another fluid) against the clamping surfaces of the work pieces chucks when a work piece is not present. The pressurized fluid impinges on the work piece chuck clamping surfaces, thereby removing chips and/or other debris therefrom.

  • Patent number: 7819392
    Abstract: A positioning mechanism in a positioning and clamping device includes an annular tapered surface that is formed on an outer periphery of a cylindrical shaft for positioning a pallet in the horizontal direction, and has a decreasing diameter toward an axial tip of the cylindrical shaft. An annular engaging mechanism, which is formed on an inner periphery side portion of an annular engagement member, is engageable with the annular tapered surface, and is elastically deformed in the radial direction, as a result of engagement with the annular tapered surface. The engaging mechanism has a tapered ring portion, which makes a face contact with the annular tapered surface, and multiple ribs extending outward, radially, from the tapered ring portion.

  • Patent number: 7793924
    Abstract: A plug member (12) inserted into a positioning hole (5) formed in a second block (2) is projected from a first block. Two slide portions (61, 61) opposed to each other across the plug member (12) are arranged around the plug member (12) movably in a first radial direction (D1) substantially orthogonal to the opposed direction. An annular pressing member (15) which is allowed to diametrically expand and diametrically contract is arranged around an outer periphery of the slide portion (61, 61). The slide portions (61, 61) diametrically expand the pressing member (15) in a second radial direction (D2) which is the opposed direction by a drive device to press the pressing member (15) against an inner peripheral surface of the positioning hole (5), by which the slide portions (61, 61) are moved in the first radial direction (D1) with respect to the plug member (12).

  • Patent number: 7748690
    Abstract: A quick-action cylinder with safety device to prevent blocking is described, wherein the quick-action cylinder provides a mechanical lock for a center draw-in nipple (2) in a center bore (23) in a housing of a quick-action cylinder, wherein in the locked position one or more locking members (3) are urged into contact with an exterior periphery of the draw-in nipple by a force of a spring assembly (12) which is arranged in the housing in one or several spring compartments (13), and wherein the unlocked position of the draw-in nipple (2) is attained by applying pressure to a locking piston (7) which operates to oppose the force of the spring assembly. The safety device prevents self-blocking of the locking device of the draw-in nipple (2) in the center bore (23) when the pressure medium enters the spring compartment (13) of the spring assembly (12) from the cylinder space (11) of the locking piston.
