Abstract
A reciprocating pneumatically driven drill motor housing for use in repetitive machining operations that uses industry standard motors, chucks and multiple spindle heads. The invention allows the user to limit set up time and obviates the need for fabricating special tooling. The unit is easily mounted on any type of fixture.
Claims10
A device for performing repetitive machining operations comprising:
- a planar rectangular mounting base having a plurality of holes for securing said base to a fixture,
- a rectangular bearing support plate secured to an upper face of said mounting base,
- a pneumatic cylinder having an extensible shaft, said cylinder centrally mounted on said upper surface of said mounting base, parallel to a long axis of the mounting base,
- an upper section having a forwardly located axially elongated cavity for holding a drill motor,
- said upper section slideably mounted on said bearing support plate so that it may move axially along said long axis and affixed to the extensible shaft of said pneumatic cylinder,
- means for supplying and controlling an air supply to said pneumatic cylinder to extend and withdraw said extensible shaft thereby providing reciprocal motion to said upper section.
3 more elements
The device of claim 3 wherein said upper section is cast rather than machined.
