Assembly machine having improved tooling mounting










Image Number 7 for United States Patent #3939544.

An assembly machine is provided having tooling mounting and surfaces and tooling actuator drivers above and below a rotatable assembly table. The annular assembly table is disposed around a main center support column within which is disposed the main driver shaft. An indexing unit rotates the annular assembly table in discrete spaced apart steps around the main support column. A lower tooling plate mounting surface and a tooling actuator driver, which is driven from the main drive shaft, is provided beneath the annular assembly table. The mounting surface is fixed longitudinally with respect to the annular assembly table while the tooling driver reciprocates with respect to the assembly table. An upper tooling mount is provided above the annular assembly table. The upper annular tooling mount is disposed around the main center support column and moves in a reciprocating up/down motion with respect to the annular assembly table. Tooling for performing various operations on devices to be assembled which are mounted on the assembly table can be connected to the upper tooling mount. An upper actuator driver is provided above the upper tooling mount and the lower actuator driver is provided beneath the annular assembly table. An actuator is provided for transmitting power from the upper actuator driver to tooling mounted on the upper tooling mount. An actuator is also provided for transmitting power from the lower actuator driver to the tooling mounted on the lower mounting plate. The upper and lower actuator drivers move in reciprocal up and down motion along the main center support column. Self-aligning roller assemblies are utilized on the lower driver, the upper tooling mount and the upper actuator driver for spacing these devices away from the main center support column and providing for easy longitudinal movement along the main center support column. The roller assemblies include a nylon roller which can move easily along the main center support column. The roller assemblies can be removed from the outside of the assembly machine without disassembling any other portion of the assembly machine. Rotational movement of the upper actuator driver, the lower actuator driver and the upper tooling mount is prevented. The main center drive shaft is disposed within the main center support column. This is driven by appropriate drive assemblies. Various cam and cam follower arrangements are provided between the main center drive shaft and the upper actuator driver, the lower actuator driver and the upper tooling mount to move the upper actuator driver, the lower actuator driver and the upper tooling mount in a reciprocal up and down motion which is a function of the selected cam and cam follower assembly. The roller assemblies which can be attached externally to the upper actuator driver, the lower actuator driver and the upper tooling mount serves to accurately align these items around the main center support column.
