Abstract:
A router guide apparatus for use in forming rosette designs in a work piece includes a frame having a work surface with a wheel rotatably mounted upon the work surface. The wheel has a plurality of position stops. The frame includes an adjustable guide for holding and a tracking a router with a cutting blade. The frame includes stops for limiting movement of the router during use. The guide and stops are configured to enable the cutting blade to cut two petals of a rosette design in a single pass. The wheel is affixable into multiple angular positions relative to the guide so that multiple cuts can be made at different angular orientations relative to one another.
Abstract:
An indexing device comprising a base table (10), a turret (11) which indexes about a given rotary center relative to the base table (10), a pair of positioning engaging members (27) provided between the base table (10) and the turret (11), wherein at least one of the positioning engaging members (27) has an inclined tooth profile, and the positioning engaging members (27) are engageable with and disengageable from each other relative to the tooth profiles when they move in axial directions thereof relative to each other. The meshing of the tooth profiles are maintained by applying a pressing force to at least one of the positioning engaging members (27). When the turret (11) receives a load, a positioning displacement which occurs between the pair of positioning engaging members (27) is detected, and the pressing force applied to the positioning engaging members (27) is adjusted based on the result of detection.
Abstract:
A gearless indexing device for positioning and repositioning a workpiece to be machined in accordance with a desired system or predetermined program has a housing means, a bore end to end therethrough in which an actuating shaft is rotatably mounted. The workpiece is fixedly connected to one end of the actuating shaft and fixedly connected about the actuating shaft a spaced distance from the workpiece is an actuating assembly disposed for operative connection with the actuating shaft; the actuating assembly having, a suitable measuring device for establishing the predetermined measured distance for positioning and repositioning the workpiece, and a unique gearless transfer assembly for transmitting this measured distance to the actuating shaft and for rotating the actuating shaft serially in step by step arcuate distances each equivalent to the predetermined measured distance. A locking assembly is disposed for detachably, selectively and operatively connecting the gearless transfer assembly to the actuating shaft to serially move the actuating shaft an arcuate distance equivalent to said predetermined measured distance for positioning and repositioning the workpiece to be machined in accordance with the predetermined program.
Abstract:
A fixture for indexing a work piece, a machine spindle, or the like permits indexing a single rotation of the work piece or other mechanism in any integral number of equal divisions. Stops for the divisions are made to suit the job by assembling a standard roller chain with as many pins and pin spaces as there are to be divisions and mounting the chain about a tapered body, preferably a cone. Fixtures hold the chain at the plane in which the periphery of the cone is the right diameter to receive the chain and other parts adjust the indexing stop to overlie the roller chain at that plane. Adjustments are provided to adjust the indexing stop peripherally of the cone a short distance in order to bring the indexing stop to the required rotational position. This adjustment may also be used to adjust the rotatable part a fraction of an indexing stop.
Abstract:
A pair of turrets of a punch press are rotatably coupled to a common drive shaft by chains and sprockets. Releasable couplers are placed between the chains and the drive shaft to allow relative, limited movement between the turrets and the common drive shaft during the insertion into the turrets of alignment shot pins. The limited relative movement allows the turrets to independently, accurately position during insertion of the shot pins without placing strain on the chains, drive shaft or power source.
