Abstract
A work piece positioning device which has a table upon which the work piece is supported is disclosed. The table is rotatably mounted on a sub-assembly which is tiltably mounted on a frame such that the work piece can be positioned in any desired predetermined attitude. Two worm gear systems are utilized for positioning the table, one for the rotating action and one for the tilting action. Each worm gear system has a worm gear, a tiltable worm and a locking mechanism. Once the table and work piece are in the desired predetermined attitude, the locking mechanisms are actuated, locking each worm to its respective worm gear.
Claims9
A machine for positioning a support for work pieces comprising:
- frame means;
- co-axially spaced supports mounted on said frame means;
- a first worm gear fixedly mounted on one of said spaced supports;
- a first sub-assembly rotatably mounted on said co-axially spaced supports;
- a second sub-assembly rotatably mounted on said first sub-assembly and carrying said work support;
- a first worm rotatably mounted on said first sub-assembly and selectively positionable in driving or locking engagement with said first worm gear;
- a second worm gear fixedly mounted on said second sub-assembly and rotatable therewith;
- a second worm rotatably mounted on said first sub-assembly and selectively positionable in driving or locking engagement with said second worm gear;
- a first motor mounted on said first sub-assembly and connected in operative driving relationship with said first worm;
- a second motor mounted on said first sub-assembly and connected in operative driving relationship with said second worm;
- means for selectively positioning said first worm in driving or locking engagement with said first worm gear;
- and
- means for selectively positioning said second worm in driving or locking engagement with said second worm gear,
- said support for work pieces being positionable in a desired attitude by operation of one or both of said motors and being secured in said desired attitude by positioning said first and second worms in locking engagement with said first and second worm gears, respectively.
A machine for positioning a support for work pieces comprising:
- frame means;
- co-axially spaced supports mounted on said frame means;
- a first worm gear fixedly mounted on one of said spaced supports;
- a first sub-assembly rotatably mounted no said co-axially spaced supports;
- a second sub-assembly rotatably mounted on said first sub-assembly and carrying said work support;
- a first worm rotatably mounted on said first sub-assembly and positioned in driving engagement with said first worm gear;
- a second worm gear fixedly mounted on said second sub-assembly and rotatable therewith;
- a second worm rotatably mounted on said first sub-assembly and positioned in driving engagement with said second worm gear;
- a first motor mounted on said first sub-assembly and connected in operative driving relationship with said first worm;
- and
- a second motor mounted on said first sub-assembly and connected in operative driving relationship with said second worm,
- said support for work pieces being positionable in a desired attitude by operation of one or both of said motors.
