Description

[0001] The present invention relates to a machine tool vise for machining area extension,

The present invention relates to a machine tool vise for expanding a table machining area, and more particularly, to a machine tool vise for expanding a table machining area, in which a fixed side jaw and a flow side jaw position setting are independently performed, And more particularly to a machine tool vise for expanding a table machining area, which is excellent in clamping area expandability with respect to a Y-axis direction of a machining center having a narrow machining area.

In a machine tool such as a machining center, a tool is installed and rotated in a main shaft, a workpiece is placed on a table, and a machining process is performed by the x and y axis feed forces of the main shaft and the table. A vise is fastened to fasten in place.

The vise is fixed to the upper surface of the table and has a bed portion having a bed surface and a fixed side jaw at one side and a flow side jaw which is installed at another side of the body portion and is transported on the bed surface by a screw operating force, It is necessary to provide a wide variety of vices corresponding to various sizes of workpieces in accordance with various sizes of workpieces. In particular, when the vice are formed in a large size, it is troublesome to attach and detach using a crane due to a heavy load, The failure rate is increased and the machining precision is lowered.

[0004] Conventionally disclosed in Japanese Patent Laid-Open Publication No. 10-1098770 discloses a machine tool having a first support member mounted on one side of a bed of a machine tool, a second support member provided on the bed so as to be spaced apart from the first support member, And a screw shaft provided between the first and second support members for performing a sliding operation and having a moving jaw and a screw shaft which is fitted to the first supporting member and fastened and fixed to the fluid, A technology for freely adjusting the temperature of the liquid is preliminarily registered.

However, the above-mentioned prior art has raised many problems in clamping range extensibility and clamping precision in the use of a technique for clamping workpieces of various sizes in a single vice.

First, since the first and second fixing members and the fluid having the fixing jaws and the moving jaws are installed in the guide grooves of the bed, the clamping area that is wider than the guide groove size can not be provided. Axis direction, so that there is a limit in the use in which the action in the y-axis direction of the bed is impossible.

Secondly, although the screw shaft operating force acts on the upper part of the fluid body in order to prevent the workpiece from being lifted by the moving jaw holding force, the workpiece is shaken when the working force is applied due to the feeding operation tolerance between the lower protrusion of the fluid body and the guide groove of the bed And the machining precision was lowered.

Third, as the fluid moves along the guide grooves of the bed, there is a problem that the bed surface is abraded by repetitive friction action.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a clamping apparatus, And it is an object of the present invention to provide a machine tool vise for expanding a table machining area, which is capable of preventing lifting of a workpiece, and particularly having a clamping area expandability with respect to a Y-axis direction of a machining center having a narrow machining area.

In other words, the expansion tables 12 and 22 and the fixed and flow side jaws 14 and 24 are formed to be at right angles to the ' (Viz., Hard) in an integral or heterogeneous manner with the fixed, flow-side vise 10 (20). The extension tables 12 and 22 are provided so as to be parallel to the machine tool table 1 so that the bottom surface of the workpiece A is locally interposed and supported while being spaced apart from the machine tool table 1. [

1 to 3, the drive means 23 has a manual control structure using a screw, but the present invention is not limited to this, and it is also possible to apply an automatic control structure using a screw, a ball, or a hydraulic actuator by a drive source Do.

On both sides of the fixed vortexes 10 and 20, a long hole 32 is formed in the longitudinal direction corresponding to the section of the expansion tables 12 and 22, and a position control plate (not shown) 30 are provided. The position regulating plate 30 is extended to both sides of the fixed and flow side vise 10 and 20 so that the bottom surface is interposed on the machine tool table 1 and is fixed to the fixture J 3, the fixture J is screwed to the T-shaped nut inserted and positioned in the T-groove 2 of the table 1 to fix the position control plate 30 to the table 1. [ . The elongated hole 32 is formed so as to have a length corresponding to a section in which the extension tables 12 and 22 are formed and to be positioned within a range corresponding to the length of the elongated hole 32.

The position regulating plate 30 is fastened to the T-shaped groove 2 located at the edge of the machine tool table 1 through the elongated hole 32 and moves in the longitudinal direction of the elongated hole 32, Is capable of clamping the work (A) in an area extending beyond the machine tool table (1).

As shown in FIG. 3, since the elongated hole 32 of the position adjusting plate 30 is provided on the side of the vise 10 (20) so as to correspond to the section of the extension tables 12 and 22, When the position adjustment plate 30 is fastened to the groove 2 and fixed in the longitudinal direction of the elongated hole 32 and the flow side vise 10 or 20 is positioned, the extension tables 12 and 22 are moved to the machine tool table 1), the area of the expansion table 12 (22) supporting the bottom of the work (A) is expanded, and the fixed side, the side side jaws (14) 24, The clamping area of the table 1 of the small machine tool can be easily expanded by expanding the clamping area of the machining center with respect to the Y-axis direction.

On the other hand, the angle of the stationary flow vise 10 (20) is adjusted by the slot 32 of the position adjusting plate 30, so that the side faces of the work A pressed against the vise are not parallel Even when the side jaws are adjusted so as to be closely contacted with the side surface of the workpiece, the workpiece (A) can be clamped in various shapes and the clamping force can be firmly maintained.

At this time, the flow side jaws 24 are moved along the guide holes 26 formed in the flow side vise 20, and the support grooves 24a The stanchion 23a and the receiving groove 24a are formed to be conical or hemispherical so that the center of the rotary shaft of the stanchion 23a is spaced upward from the center of the receiving groove 24a.
