Work device and its moveable claw
First Claim
1. A vice for mounting on an elongated base comprising a slide guide mounted on said base in parallel longitudinal directions:
- a first moving base having an upper portion and a lower leg portion, said lower leg portion slidably attached to said slide guide;
a second moving base capable of moving in an advancing direction of said first moving bases, being separated from said first moving base and sent out toward an advancing direction of said first moving base by a feed screw means attached to said first moving base for advancing and retracting said second moving base relative to said first moving base;
a plurality of cooperating positioning means arranged at a predetermined pitch in said elongated base and the lower surface of said second moving base to selectively position said first moving base;
a movable claw arranged on an advancing direction side of said second moving base and gripping one end of a work; and
an arched roof portion integrally formed with an upper portion of said second moving base and extending over the upper portion of said first moving base, a lower face of said roof portion slidably coming in contact with said first moving base forming a sliding face parallel to said slide guide said roof portion protecting said first and second movable bases from entry of foreign material.

Abstract
A work vice of a work includes a first moving base slidably attached to a slide guide arranged in parallel with an elongated fundamental base in a longitudinal direction of the fundamental base, a second moving base capable of approaching an advancing direction side of the first moving base and being separated on the advancing direction side and sent out toward an advancing direction of the first moving base by a feed screw attached to the first moving base, a plurality of positioning means arranged at a predetermined pitch in the fundamental base to position and fix a leg portion side of the first moving base, a movable claw arranged on an advancing direction side of the second moving base and gripping one end of a work, and a pent roof portion having a gate shape and integrally formed with an upper portion of the second moving base on the first moving base side, a lower face of the pent roof portion slidably coming in contact with the first moving base on a sliding face parallel to the slide guide.

7. A work vice as claimed in claim 6, wherein said pushing-down face of said base block and said downward moving face of said claw block are set to multistage cylindrical faces rotatably adjustable in a horizontal direction with one central axis.
-
8. A work vice as claimed in claim 7, further comprising means for securing an adjustable vertical position of said base block relative to said claw block.
-
9. A work vice as claimed in claim 1, wherein said lower leg portion of said first moving base has a width larger than a width of said upper portion of said first movable base forming a shoulder portion forming said sliding face.
