A workpiece holder device for workpieces to be machined on multiple sides, wherein the workpiece can be held axially and radially relative to the first axis between a first workpiece holder, operatively connected to at least one support spindle of the workpiece holder device and rotatable about a first axis, and at least one second workpiece holder, operatively connected to at least one drive spindle of the workpiece holder device and rotatable around the first axis, by force locking by a clamping force which can be built up in the manner of a vice between the first workpiece holder and the second workpiece holder in the axial direction of the first axis and acting on the opposite sides of the workpiece.

I, Robert Thomas Wilson, being the inventor, have designed this Centering Fixture. This invention is described in enabling detail in the following example which may represent more than one embodiment of the present invention. The Centering Fixture is an accessory attachable to a milling machine vise, it centers similar pieces of material with dimensional variations. Machining processes often begin with cutting a number of pieces from larger stock. These cut pieces will vary due to accuracy limitations of the cutting method used. The Centering Fixture, incorporates two movable extensions that precisely move toward or away from one another at the same rate by rotating a leadscrew having a right-hand thread on one end and a left-hand thread on the other. Using this Centering Fixture material regardless of dimensional variations from one piece to the next are each individually centered aiding in accurate manufacturing. As an example, a cut piece 4.030 inches long would be set up with the 2.015-inch center position of that piece oriented as desired. If the next piece measured 4.120 inches long the Centering Fixture would automatically locate the center of that piece at the 2.060-inch position. This centering function would then repeat with all subsequent like pieces, in this example and in one embodiment. The Centering Fixture is portable allowing easy movement from one machine to the next.

A universal manufacturing vise jaw plate for use on a machine tool with a vise fixture, and configured for real-time operational data collection and analysis. The vise plate comprises a combination of acoustic and vibration sensors with a plate for cutting tool monitoring applications.

Rotating vise jaws comprising first, second, third, and forth elements used with a milling machine vise to hold objects having either parallel or nonparallel edges. Wherein, said first element consists of a vertical axis tool post adapted to fit either a movable or stationary wall disposed at a milling machine vise. Said vertical axis tool post disposes a cylindrical shaft defining a vertical axis for cooperating with said second element comprising a vertical axis vise jaw having beveled side walls and a correlative through hole for cooperating with said vertical axis. Thus, said vertical axis tool post is attached to a milling machine vise and said vertical axis vise jaw is connected to said vertical axis, thereby providing a self-aligning vise jaw with a reversible clamping face; wherein said vise jaw is rotatable about a vertical axis for holding objects having either parallel or nonparallel edges.

Wherein, said third element consists of a horizontal axis tool post having a correlative through hole for connecting said horizontal axis tool post to said vertical axis. said horizontal axis tool post disposes a cylindrical shaft defining a horizontal axis for cooperating with said forth element comprising a horizontal axis vise jaw having beveled side walls and a correlative through hole for cooperating with said horizontal axis. Thus, said vertical axis tool post is attached to a milling machine vise, said horizontal axis tool post is connected to said vertical axis, said horizontal axis vise jaw is connected to said horizontal axis, thereby providing a self-aligning vise jaw with a reversible clamping face, wherein said vise jaw is rotatable about a horizontal axis for holding objects having either parallel or nonparallel edges.

This processing device is provided with: a tool for machining a workpiece W along the thickness direction thereof, the width-direction external shape of the workpiece W being substantially finished; and a flexible vice 7 that clamps the workpiece W in the width direction without clamping the workpiece W in the thickness direction. The flexible vice 7 is provided with a position adjustment mechanism that prevents the position of the workpiece W from changing in a plane along the width direction before and after the workpiece W is clamped. The present invention is provided with a rough processing tool for performing processing at a rough-processing position, a finishing processing tool for performing processing at a finishing-processing position, and a control unit that causes the position adjustment mechanism to move between the processing performed by the rough processing tool and the processing performed by the finishing processing tool.

The disclosure relates to a holder system for supporting sports equipment. The holder comprises a vise assembly comprising: a vise base; two moveable vise jaws provided with respective vise screw bores and guide bores, the two moveable vise jaws engageable with a first section on the sports equipment; a vise screw extending substantially horizontally through the vise base and oppositely disposing the movable vise jaws through the vise screw bores, and having two sections of threads allowing for movement of the movable vise jaws, the two sections being separated by a thread-free section; and one or more guide bars fixed in a substantially horizontal orientation in the vise base and extending through the respective guide bores.

A side stop device used to locate and relocate the left to right, or X direction, position of work material held by a machine vise is disclosed. The side stop device comprises an X direction shaft which fastens the side stop device to the vise, a rear block, a front block, and a Y direction shaft. The X direction shaft and Y direction shaft are fastened to the rear block. The Y direction shaft is fastened to the front block which clamps a small X shaft. The position of the small X shaft is used to locate the work material in the X direction.

The rotary workhead device, which is loaded on the table of a machine tool and onto which a workpiece to be machined is rotatably mounted, is equipped with: a base plate that is attached to the table of the machine tool; two rotary workheads that are provided on the base plate and disposed so that the axes of rotation coincide and the workpiece-fixing parts face each other; a guide means that is provided so as to be capable of moving at least one of the rotary workheads back and forth in the direction of the rotation axes; and an impelling means for impelling the one rotary workhead in a direction that separates or brings together the two rotary workheads. The rotary workhead device applies a tensile force or a compressive force on a workpiece, the respective ends of which are fixed between the two rotary workheads.

In a clamping fixture 1, in particular a vice, with a housing (2) in which a guide track (10) is provided and with at least one base jaw (3, 4) to each of which a clamping jaw (6, 7) can be attached, the cavities or air gaps (21) between the inner wall of the guide grooves (10) and the base jaws (3, 4) should be completely covered.

This is achieved in that a seal (11) is inserted into each of the air gaps (21) existing in the housing 2 between the base jaw (3, 4) and the inner wall of the guide track (10) as well as in the parting plane between the base jaws (6, 4) and at the face ends (16) in the area of the guide track (10) running there, and that the particular seal (11) is held in a specified position by means of a support strip (12).
