Abstract

A vise assembly, for use on a drill press having a vertical cylindrical column and a table with a flat upper surface substantially perpendicular to the column, has a mounting block slidably and rotatably mounted on the column and a frame slidably mounted on the mounting block for movement parallel to the flat top surface of the table. The frame includes a back plate, at least two pairs of rods connected to the back plate, fixed and movable jaws, one of the pair of rods being connected to the fixed jaw and the other of the pairs of rods being connected to the movable jaw. The jaws normally rest on the table. In the preferred embodiment, hydraulic cylinders, carried by the back plate, are connected to move the pair of rods connected to the movable jaw. In another embodiment, a manually operated screw arrangement is used to move one pair of rods relative to the other, to move the movable jaw toward the fixed jaw. The entire frame may be moved manually toward and away from the column and rotated with respect to the column so as to position the jaws in any desired position with respect to the table, before or after a workpiece has been mounted in the jaws.

Claims

1. A vise assembly for use on a drill press having a vertical cylindrical column, said assembly comprising mounting means slidably and rotatably mounted on and around said column and projecting laterally beyond said column on diametrically opposite sides, said mounting means having journal passages on either side of said column the long axes of which are parallel to one another and substantially perpendicular to said column;

a pair of rods slidably journaled in said mounting means passages, said rods projecting from said mounting means in both directions;

a second pair of rods extending paralled to said first pair of rods;

a fixed vise jaw, one of said pairs of rods being mounted at one end to and against movement relative to said fixed vise jaw;

a movable vise jaw, the other of said pairs of rods being connected at one end to said movable vise jaw;

a back plate, both of said pairs of rods being mounted in said back plate; and

means carried by said back plate for moving said movable jaw rods with respect to said fixed jaw rods, hence said movable jaw with respect to said fixed jaw, said mounting means supporting said rods and back plate, whereby said jaws can be moved concurrently toward and away from said column and can be rotated, while maintaining their positions relative to one another, about said column.

2. A vise assembly for use on a drill press having a vertical cylindrical column and a table with a flat upper surface substantially perpendicular to said column, said assembly comprising mounting means slidably and rotatably mounted on said vertical column, and a frame slidably mounted on said mounting means, parallel to the upper surface of said table, for movement toward and away from said column, said frame including a back plate, at least two pairs of rods connected to said back plate, at least one of said pairs of rods being journaled for lengthwise movement in said mounting means;

fixed and movable jaws, one of said pairs of rods being connected to said fixed jaw and the other of said pairs of rods being connected to said movable jaw, and drive means carried by said frame for transmitting force between said back plate and said movable jaw for moving said movable jaw toward said fixed jaw, said frame being swingable about and translatable toward and away from said column.

3. The assembly of claim 2 wherein the rods of the pair connected to said fixed jaw are slidably journaled in said mounting means, and the drive means comprise hydraulic cylinders mounted at one end on said back plate outboard of said fixed jaw rods, and operatively connected to the pair of rods connected to said movable jaw.

4. The assembly of claim 2 wherein the drive means comprise threads on one pair of rods threaded into complimentary threaded members, and means for rotating said threads and threaded members relative to one another to move the rods, hence one jaw, relative to the other jaw.

5. The assembly of claim 4 wherein the rods of the pair of rods connected to the fixed jaw are selectively clamped in the back plate.

6. A vise assembly for use on a drill press having a vertical cylindrical column, said assembly comprising mounting means rotatably mounted on and around said column, projecting laterally beyond said column on either side;

slide rods slidably journaled in said mounting means on either side of said column parallel to one another, said rods projecting beyond said column in both directions;

a back plate carried by said rods at one end of said rods;

a fixed jaw member mounted on the other end of said rods against movement with respect to said rods;

a movable jaw member, and drive means supported by said back plate and connected to said movable jaw member for moving said movable jaw member with respect to said fixed jaw member.

7. A vise assembly for use on a drill press having a vertical column with a table with a flat upper surface substantially perpendicular to the long axis of said column, said assembly comprising a mounting block rotatably and slidably mounted on said column above the flat upper surface of said table, said mounting block having a pair of journal passages paralled to one another, one on either side of said column, the long axes of said journal passages lying in a plane parallel with said flat upper surface of said table;

slide rods slidably mounted in said journal passages;

a back plate carried by said slide rods at one end of said slide rods on the side of said column away from said table;

a fixed jaw member mounted on the other end of said rods against movement with respect to said rods, said fixed jaw member having a lower surface resting on said flat upper surface of said table;

a movable jaw member positioned between said fixed jaw member and said column, having parallel passages spaced and aligned slidably to receive said slide rods and a lower surface resting on said flat upper surface of said bed; and

drive means, supported at one end by said back plate and extending between said back plate and said movable jaw member, for moving said movable jaw member toward and away from said fixed jaw member, said drive means comprising hydraulic cylinders mounted at one end on said back plate and having drive rods connected at their outer ends to said movable jaw member.
