Tool housing and method for making the same
A tool housing and method for making the same are disclosed. The tool housing can include upper and middle portions that are fully machined and coupled to one another. The tool housing can also include a lower housing that is partially machined, coupled to the remaining housing portions, and then fully machined. In doing so, the machining operation is eased and the portions of the housing are better aligned with one another.
1. A tool housing comprising:
an upper housing portion having a transversely oriented tool head opening adapted to receive a tool head and a first threaded opening;
a middle housing portion having first and second ends, the first end includes threads disposed on an external surface thereof and a collar, wherein the first end is threadably coupled to the first threaded opening, and wherein the second end includes a second threaded opening having threads disposed on an internal surface of the second threaded opening; and
a lower housing portion having first and second lower housing portion ends, the first lower housing portion end including an extension having threads disposed on an external surface thereof and is threadably coupled to the second threaded opening, and the second lower housing portion end including a body portion having a slot and that is adapted to be removably coupled to a main body of a tool, wherein the main body of the tool houses a motor, wherein the upper housing portion includes a rim adapted to receive the collar to align the middle housing portion with the upper housing portion.
2. The tool housing according to claim 1 , wherein the lower housing portion includes a base disposed between the extension and the body portion, and the middle housing portion includes an indent.
3. The tool housing according to claim 1 , wherein the body portion further includes a cut out.
4. The tool housing according to claim 1 , wherein the body portion further includes a collar.
5. The tool housing according to claim 1 , wherein the lower housing portion further includes a base portion disposed between the extension and the body portion, and a flange disposed between the base portion and the body portion, wherein the flange provides a structural interface between the base portion and the body portion.
6. The tool housing according to claim 1 , wherein the tool head is a ratchet head.
