Abstract
A bottom-loading pot broaching machine has a pot broach vertically mounted on a horizontal face of a base support structure to symmetrically distribute loading forces to the machine. This structure also enables loading and unloading arms to be mounted to the pot broach so as to be mechanically coupled and phased to allow both loading and unloading of the pot broach during a single cycle. A magnetic escapement mechanism is mounted proximately to the unloading arm to magnetically retain a finished workpiece for unloading by the unloading arm.
Claims7
A pot broaching machine having an integrated workpiece transfer mechanism comprising:
- a mounting member;
- a pot broach mounted to said mounting member and having a rough workpiece inlet at one end and a finished workpiece outlet at an opposite end;
- a rough workpiece loading arm mounted proximately to the inlet of said pot broach operative to move a rough workpiece to a position aligning the rough workpieces with the inlet of said pot broach;
- means operative to transfer the rough workpiece through said pot broach to produce a finished workpiece at the outlet of said pot broach;
- a finished workpiece unloading arm mounted proximately to the outlet of said pot broach operative to move the finished workpiece away from the outlet of said pot broach;
- and
- means operative to mechanically link said loading arm to said unloading arm to allow said unloading arm to move the finished workpiece away from the outlet of said pot broach whenever said loading arm moves a rough workpiece to the inlet of said pot broach.
A bottom-loading pot broaching machine comprising:
- a pot broach having an inlet end for inserting a rough workpiece therein and an outlet end for extracting a finished workpiece therefrom;
- a base structure for symmetrically supporting said pot broach thereon along a horizontal surface, the inlet end of said pot broach being rigidly affixed to said base structure;
- means, mounted to said base structure, operative to push said rough workpiece through pot broach;
- and
- mechanical mean operative to transfer a rough workpiece into the area of the inlet end of said pot broach and to transfer a finished workpiece away from the outlet of said pot broach including, a loading arm pivotably mounted at the inlet of said pot broach, an unloading arm pivotably mounted at the outlet of said pot broach, a connecting member having said loading and unloading arms phasedly mounted at opposite ends thereof, and means operative to rotate said connecting member to move said loading arm from a first position engaging said rough workpiece to a second position aligning said rough workpiece with the inlet of said pot broach while moving said unloading to move said finished workpiece away from the outlet of said pot broach.
