Abstract: A workpiece support for a vise which is used for clamping a small workpiece on the vise and which can solve the problem that the prior art workpiece support has not versatility in clamping workpieces of various different configurations. In the workpiece support, a magnet is detachably mounted in a support plate and the support plate is fixedly attracted to a jaw plate of the vise through the magnet. Therefore, by forming a step in one side of the support plate along an edge and mounting the magnet in the support plate in a reversible manner, any one surface of the workpiece support can be selected as an attraction surface and the workpiece support can be used in many various forms depending on the workpiece configurations.

Abstract: A pair of slide plates are vertically displaceably fixed to the opposed front surfaces of a fixed jaw and a movable jaw constituting a vice. An arbitrary number of presser members for pressing a work are fixed on the upper surfaces of the fixed jaw and the movable jaw. The work is placed on upper ends of the slide plates adjusted in height, and a pressure from setscrews of the presser members is applied to the upper surface of the work. Accordingly, even when the work is a thin plate-shaped work, it can be stably held to prevent possible vertical curving of the work.

Abstract: The present invention relates to an article fixing device for fixing an article to be mounted to a mounting surface of a mounting member removably. Both sides of the mounting member are grippingly fixed by a pair of pivoting members mounted to the article to be mounted. The article to be mounted can be mounted in close contact with the mounting surface of the mounting member by rotating forces of the pivoting members.

Abstract: The present invention relates to a work holder for a vice in a machine tool, in which by means of a holder body attached removably to a fixed jaw of the vice and a clamp block and a clamp screw both attached to the holder body, a work whose side faces have already been machined is fixed temporarily in an exact vertical posture and then fixed completely by the vice so that the side faces thereof are set exactly at right angles to permit machining for the top face of the work.

Abstract: The present invention relates to a work holding vice jig to be attached to a jaw of a vice. According to the construction of this vice jig, grooves are formed in a work holding surface of the jig body so that works of special shapes, e.g. a round bar, can be clamped to the vice easily; further, a slide member which is slidable obliquely relative to the jig body is provided, and works of various thicknesses can be clamped to the vice efficiently by upward and downward sliding motions of the slide member.
