Abstract

An end finisher machine is disclosed. A longitudinal base mounts a stabilizer block which in turn mounts a high speed shaft or spindle, the spindle extends through a head having a camming surface and mounts a tooling assembly at its distal end. A motor drives the spindle at high speeds. A workpiece is placed in a tool holder mounted on the base adjacent the head. A first drive cylinder moves the stabilizer block and the tooling assembly to a correct axial position adjacent the workpiece. A second drive cylinder moves the head to cam the tooling assembly to drive the tools to perform the desired tooling operation.

Claims

1. An end finisher machine comprising a longitudinally extending base, a workpiece holder mounted on said base, a stabilizing block assembly mounted on said base, a rotatable shaft extending from said block assembly toward said workpiece holder, a head assembly surrounding said shaft for movement along said shaft, said head assembly defining an opening at one end, a tooling assembly mounted on said shaft within said head assembly opening, said head assembly and said tooling assembly defining mating surfaces wherein longitudinal movement of said head assembly opens and closes said tooling assembly, a stop assembly mounted adjacent said workpiece holder, said stop assembly including a pivotal arm movable between a stop position for engaging a workpiece adjacent said tooling assembly and an outer position, motor means for rotating said shaft, first cylinder means for moving said stabilizing block assembly and said tooling assembly toward and away from said workpiece holder and second cylinder means for moving said head assembly and its mating surface toward and away from said mating surfaces of said tooling assembly, said tooling assembly including a tooling shaft member fixed to said shaft within said head assembly opening, a plurality of tool holders mounted for radial movement on said tooling shaft member, springs mounted between said tooling shaft member and said tool holders for urging said tool holders radially outwardly, and holding means on said tool holders for holding the tools.

2. An end finisher machine, according to claim 1, wherein said tooling shaft member defines a plurality of radial channels, each of said tool holders including a slide member mounted for radial movement in one of said plurality of radial channels, and a generally "U" shaped retaining member attached to said slide member, said holding means for retaining the tools comprising a tool shaft mounted by said retaining member.

3. An end finisher machine, according to claim 2, including a longitudinal bearing assembly between said tooling shaft member and each of said slide members.

4. An end finisher machine, according to claim 2, including adjusting means between each of said slide members and its respective retaining member for adjusting said tools.

5. An end finisher machine, according to claim 2, wherein each of said slide members defines a recess adjacent said tool shaft member, said recess receiving one of said springs.

6. An end finisher machine, according to claim 1, wherein said base defines an opening for receiving a completed workpiece.

7. An end finisher machine, according to claim 1, wherein said motor means rotates said shaft at operating speeds between 200 RPM and 5000 RPM.

8. An end finisher machine, according to claim 1, including first adjusting means for axially adjusting the position of the stabilizing block assembly and said head assembly relative to said workpiece holder.

9. An end finisher machine, according to claim 8, including second adjusting means for adjusting said mating surface of said head assembly relative to said mating surface of said tooling assembly.

10. An end finisher machine, according to claim 1, wherein said base defines a longitudinally extending guide rail, a first bearing assembly mounted on said guide rail, said first bearing assembly mounting said stabilizing block assembly.

11. An end finisher machine, according to claim 10, including a second bearing assembly mounted on said guide rail, said second bearing assembly mounting said head assembly.

12. An end finisher machine comprising a longitudinally extending base, a longitudinally extending guide rail defined by said base, said guide rail having opposed ends, a workpiece holder mounted adjacent one end of said guide rail, a stabilizing block assembly mounted on said guide rail adjacent the other end, said stabilizing block assembly including a shaft bearing assembly, a rotatable shaft mounted by said shaft bearing assembly and extending toward said workpiece holder, motor means adjacent said stabilizing block assembly for rotating said shaft, said shaft having a distal end, a head assembly mounted along said shaft for axial movement relative to said shaft, said head assembly defining an opening at one end, a tooling assembly mounted on said distal end of said shaft adjacent said head assembly opening, a stop assembly mounted adjacent said workpiece holder, said stop assembly including a pivotal arm movable between a stop position for engaging a workpiece adjacent said tooling assembly and an outer position, said head assembly and said tooling assembly defining mating camming surfaces, wherein axial movement of said head assembly relative to said tooling assembly opens and closes said tooling assembly, a first bearing assembly mounted for movement on said guide rail, said first beating assembly mounting said stabilizing block assembly, first cylinder means operatively connected to said stabilizing block assembly, a second bearing assembly mounted for movement on said guide rail, said second bearing assembly mounting said head assembly, second cylinder means operatively connected to said head assembly, said tooling assembly including a tooling shaft member fixed to said shaft within said head assembly opening, a plurality of tool holders mounted for radial movement on said tooling shaft member, springs mounted between said tooling shaft member and said tool holders for urging said tool holders radially outwardly, and holding means on said tool holders for holding the tools.
