摘要： A method of forming a drive surface on an eccentric pin of a drive shaft for a scroll-type compressor is provided. First, an eccentric pin having an axis and a generally cylindrical outer surface disposed radially about the axis is provided. Next, a broaching tool having a machining face with a contour is provided. The contour may be a concave shallow bell-shaped curve. Finally, the drive surface is formed by engaging the outer surface with the machining face transverse to the axis. In this manner, the machining face forms a shape complementary to the contour on the eccentric pin thereby forming a slight crown on the drive surface. The broaching tool produces an adequate surface finish so that no subsequent machining operations to the drive surface are necessary.

摘要： A broach assembly includes an elongated base having a central upward projection and a pair of side flanges and a tapered undersurface. Releasably mounted on the projection are multiple tool holders spaced along the length of the base. The tool holders mount cutters for engaging active surfaces of the wedge slot as the broach assembly is passed through the wedge slot. Shims may be interposed between the tool holders and base to increase the elevation of the cutting surfaces relative to the undersurface of the base to progressively increase the bearing pressure of the cutting surfaces against the active surfaces of the slot during multiple passes of the broach assembly through the wedge slot.

摘要： The broach assembly includes alternate spacers and cutters arranged in a sub-assembly having a lead at a leading end and a lag at a trailing end. The cutters have side margins in excess of the margins of the spacers for cutting material from the dovetail slots of the turbine wheel as the broach assembly passes through the slots. The bottom or apices of each spacer is tapered and extends beyond the corresponding surface of the cutter to progressively displace the assembly in a radial outward direction to progressively cut the active dovetail slot surfaces. Shims may be disposed in the bottom of the slot to further displace the broach assembly radially outwardly in multiple passes.

摘要： The broach assembly includes alternate spacers and cutters arranged in a sub-assembly having a lead at a leading end and a lag at a trailing end. The cutters have side margins in excess of the margins of the spacers for cutting material from the dovetail slots of the turbine wheel as the broach assembly passes through the slots. The bottom or apices of each spacer and cutter are tapered to form a continuously tapered surface along the bottom of the broach assembly. Upon passing the broach assembly through the slot, the assembly is progressively displaced in a radial outward direction to progressively cut the active dovetail slot surfaces. Shims may be disposed in the bottom of the slot to further displace the broach assembly radially outwardly in multiple passes.

摘要： A tool retention apparatus for retaining a cutting tool in a tool holder which has a wedged shaped securing arrangement to hold the cutting tool against a pair of precision ground supports. The securing member provides both a vertical securing force and a radial location of the cutting tool to facilitate installation and removal of the cutting tool from a machine.
