Therefore, such a connected vise structure is suitable for production of small quantity and multi-products, and thus can have a very efficient working efficiency.

In addition, Figure 7 shows another example of use of the connected vise of the present invention. This example is well suited when the shape of the welded structure or the like is not constant and it is necessary to fix the workpiece from top to bottom, ie vertically. This example is also very useful for workpieces that can be damaged when fixed horizontally and must necessarily be fixed in the vertical direction.

In more detail, the moving part rail 3 is fixed to the bed with a bolt or the like while the moving block 3 is fixed. And it is located on the same axis as the moving block (3) and the fixed part rail 5 is coupled to the fixed block 11 is fixed to the bed at a fixed distance. Thus, the moving part rail 3 and the fixing part rail 5 are respectively fixed in the required position. The workpiece W is moved from the side by disposing a workpiece such as a welded structure between the movable block 9 and the fixed block 11 and rotating the rotary member 25 to move the movable block 9 in the same manner as described above. Fix it.

Then, the nut 55 of the vertical fixing means coupled to the upper portion of the movable block 9 and the fixed block 11 is slightly loosened so that a part of the pressing member 53 is placed on a part of the upper surface of the work W. Then tighten the nut 55 again. Then, the pressing member 53 may fix the work W from the top to the bottom. Several vertical fixing means are fixed in the same manner as described above. This makes it possible to work with a variety of shapes, not only horizontal fixation, but also the workpiece can be fixed very easily when vertical fixation is required.

In addition, even when the shape of the bottom of the shape of the work (W) is various, it is possible to easily fix the work has the advantage of excellent workability.

9 shows one of the methods of securing the moving rail 3, the fixed rail 5 and the connecting rail 7 to the bed. The bolts are directly coupled to the long holes 3e, 5e, 7e provided in the first extensions 3c, 3d, 5c, 5d, 7c, 7d of the respective rails 3, 5, 7 in the T-grooves provided in the bed.
