Title:
WORKPIECE VISE
Document Type and Number:
Japanese Patent JP2020104241
Kind Code:
A
Abstract:
To provide a workpiece vise for fixing a workpiece onto a table of a machine tool or to a fixture fixed to the table, that allows a smaller workpiece to be gripped and that shortens a retreat distance of a tool when rapidly feeding the tool or when rotating the table, and thereby allows machining of a small-sized workpiece with a complicated shape to be performed more efficiently.SOLUTION: As a screw mechanism 4 for making a movable jaw 2 advance and retreat relative to a movable base 3, a screw rod 45 facing a movable base 3 side is planted on the movable jaw 2, and the cylindrical outer periphery of a long nut 41 to be screwed to the screw rod is journaled to the movable base 3 in a rotatable and immovable manner in an axial direction. In the screw mechanism for making the movable jaw 2 advance and retreat by screwing relative to the movable base 3, a width of the head 21 of the movable jaw 2 is made narrower than a width of a jaw side leg part by disposing the screw rod 45 smaller in diameter than a female screw member on a movable jaw 2 side.SELECTED DRAWING: Figure 3
