Modular tool carrier for boring machine
Embodiments of the present invention provide a boring bar tool including a tool carrier adapted to translate along a boring bar. Adjustable guide members may be coupled with the tool carrier and adapted to contact the boring bar. The guide members may also be adapted to sufficiently support the tool carrier on the boring bar.
1. A tool carrier, comprising:
a first portion and a second portion adapted to releasably engage a boring bar;
a plurality of adjustable guide members adjustably coupled to the first portion and the second portion and configured to support a tool carrier on the boring bar, wherein the plurality of adjustable guide members are radially adjustable relative to the boring bar to enable selective axial movement along the boring bar and stability for a machining tool during a machining operation; and
a drive key configured to threadably engage a lead screw on the boring bar, the first portion and the second portion adapted to help retain the drive key.
2. The tool carrier of claim 1 , further comprising:
one or more pockets in the first portion and the second portion adapted to retain the plurality of adjustable guide members for movement generally toward and/or away from the boring bar.
3. The tool carrier of claim 1 , further comprising:
a plurality of cheek pieces coupled to the first portion and the second portion and configured to receive the machining tool; and
one or more coupling members coupled to the plurality of cheek pieces, wherein the one or more coupling members are configured to facilitate positioning of the machining tool with respect to the tool carrier.
4. The tool carrier of claim 3 , wherein the cheek pieces have dovetail cutouts adapted to receive a machining tool from a group consisting of:
tool holders;
spacer blocks;
slide arms; and/or
counterweight arms.
5. The tool carrier of claim 3 , wherein the one or more coupling members are further configured to couple the plurality of cheek pieces to one another, and wherein the machining tool is positioned proximal to the plurality of cheek pieces in dovetail cutouts.
6. The tool carrier of claim 3 , wherein the plurality of cheek pieces are configured to receive a first machining tool that has a first size, and subsequently, a second machining tool that has a second size, the first size being different than the second size.
7. The tool carrier of claim 1 , wherein the first portion and the second portion are hingeably coupled together and adapted to close generally around the boring bar.
8. The tool carrier of claim 1 , further comprising at least one latch member adapted to couple the first portion to the second portion of the tool carrier, and adapted to span at least a portion of the drive key.
9. The tool carrier of claim 1 , wherein the drive key is adapted to disengage from the lead screw to allow the tool carrier to remain stationary relative to the boring bar, and wherein the one or more adjustable guide members are adjustable relative to the boring bar to prevent axial movement.
10. The tool carrier of claim 1 , wherein the drive key is statically coupled to the first portion and the second portion at a first end and radially coupled to the first portion and the second portion at a second end.
11. The tool carrier of claim 3 , further comprising a slide arm adapted to slideably couple with the plurality of cheek pieces and adapted to support a tool block holder for radial adjustment substantially normal to an axis of the boring bar.
12. A modular tool, comprising:
a first portion coupled to a second portion, wherein the first portion and the second portion are configured to generally encircle a boring bar;
a plurality of guide members, coupled to the first portion and the second portion, wherein the plurality of guide members are configured for adjustment relative the to boring bar, wherein the plurality of guide members permit selective axial movement of the first portion and the second portion along the boring bar when adjusted to contact the boring bar; and
a removable drive key having a threaded portion adapted to threadably engage a lead screw on the boring bar wherein the drive key is disposed between the first portion and the second portion.
13. The modular tool of claim 12 , wherein each of the first portion and the second portion includes two spaced-apart cheek pieces adapted to carry the guide members.
14. The modular tool of claim 13 , wherein the cheek pieces have adjustable dovetail cutouts adapted to receive machining accessories from the group consisting of:
tool holders;
spacer blocks;
slide arms; and/or
counterweight arms.
