Abstract

In the machining or lapping of surfaces on a part or module, it is sometimes necessary to machine or lap parts which have different apex locations. To do this often requires shims or different fixtures to locate parts having different apexes. This problem can be overcome by providing a fixture having means for adjusting the position of the part in accordance with changes in apex location.

Development Contour Fixture

In the machining or lapping of surfaces on a part or module, it is sometimes necessary to machine or lap parts which have different apex locations. To do this often requires shims or different fixtures to locate parts having different apexes. This problem can be overcome by providing a fixture having means for adjusting the position of the part in accordance with changes in apex location.

In the figure, tool body 1 supports an adjustable head assembly 2. The body 1 is mounted in a machining or lapping tooling block. Part support arms 3 provide support for a part to be machined. Locking screw 4 secures assembly 2 to body
1. Assembly 2 is adjustably rotated on body 1 by means of adjusting screw 6 and adjusting pin 7. The amount of rotation of assembly 2, with respect to body 1, is calibrated on a vernier which is located along the boundary between body 1 and assembly 2 as generally indicated by arrow 5. The fixture provides a large uncluttered surface in this area so as to provide good resolution. Thus, the amount of rotation of assembly 2 with respect to body 1 can be precisely controlled. This enables the apex of a part mounted on support arms 3 to be precisely positioned in the fixture without the need for shims or specifically designed holders.
