Description

[Detailed description of the invention] a. Purpose of the invention (industrial application field) The long workpiece processing vise according to this invention is used for grinding the surface of a long workpiece, or for grinding the surface of this workpiece. It is used when cutting the surface precisely, and is used to clamp and fix the long workpiece and hold it in a predetermined position on the table of a processing machine such as a grinder or milling machine.

(Prior art) When grinding the surface of a workpiece using a grinder or precisely cutting the surface of a workpiece using a milling machine, the workpiece must be held firmly in place on a processing table. In order to be able to
A vise 1 as shown in Figure 5 is used.

This vice 1 includes a fixed wall 3 provided at one end of the upper surface of a base 2 whose lower surface is flat, and a movable wall 4 that moves toward and away from the fixed wall 3 while maintaining a state parallel to the fixed wall 3. The distance between the fixed wall 3 and the inner surface can be adjusted by rotating a screw 5. In the illustrated example, the tip of a screw 5 is rotatably connected to the movable wall 4, and the intermediate portion of the screw 5 is connected to a screw hole 7 provided in a support wall 6 provided at the other end of the base 2.
A handle 8 screwed together and provided at the base end of the screw 5
By rotating the movable wall, the movable wall is moved laterally in FIGS. 4 and 5, so that the workpiece can be held between the fixed wall 3 and the movable wall 4. However, as a structure in which the movable wall 4 is moved in parallel by the screw 5, there is also a structure in which a screw that is attached to the base 2 so as to be rotatable only is screwed into a screw hole provided in the movable wall.

(Problem to be solved by the invention) However, in the conventional vise constructed and used as described above, the width of the fixed wall 3 and the movable wall 4 is limited, so that the workpiece is long. If it is shaku,
It was difficult to support this workpiece firmly enough. Although it is possible to increase the widths of the base 2, the fixed wall 3, and the movable wall 4, this is not preferable because the weight of the entire vise increases and the vise becomes difficult to handle.

For this reason, conventionally, when supporting a long workpiece, multiple vises were used to support the workpiece at multiple locations.
When precision machining is performed, setup work such as positioning of the workpiece becomes extremely troublesome.

The long object processing vise of the present invention eliminates the above-mentioned disadvantages.

b. Structure of the invention (Means for solving the problem) The vise for processing long objects of the present invention, like the conventional vise, has a fixed wall at one end of the upper surface of a base with a flat lower surface. A movable wall that slides on the top surface of the base while remaining parallel to the base is movable by rotating a screw attached to the base.

The feature of the vise for processing long objects of the present invention is that the inner surfaces of the fixed wall and the movable wall, which face each other, are sufficiently longer than the width of both walls and protrude to both sides of each wall. It is at the point where the cap is fixed. The shape of this cap is such that in the width direction of each wall, sloped parts are provided on both sides of a central straight part, the length of the straight part is equal to the width of each wall, and the sloped parts on both sides are are each of the same length and slightly shorter than the straight line section. The direction of inclination on both sides of the caps fixed to the inner surface of each wall is the distance between the pair of caps fixed to both walls, as the direction of inclination on both sides of the caps is the direction that moves away from the inner surface of the wall to which the caps are fixed as they move toward the end. However, the portion located between the two walls is constant, but the portion protruding from both walls becomes narrower toward the end.

Further, the thickness of the caps is formed so that it becomes thicker toward the top, and the distance between the pair of caps becomes narrower toward the top.

(Function) In the long workpiece processing vise of the present invention configured as described above, when supporting a long workpiece, there is a The above-mentioned workpiece is held between the two walls, and since not only the part located between the above-mentioned two walls but also the part protruding from both walls is sufficiently firmly held down by the sloped part of the mouthpiece, it is possible to hold a long workpiece. The workpiece will not rattle.

In other words, when the movable wall is moved toward the fixed wall by the rotation of the screw, and a workpiece is held between the ferrules fixed to the inner surfaces of both walls, the inclined portions of each ferrule protruding from the respective walls become elastic. It deforms and elastically presses the surface of the workpiece, suppresses the workpiece without rattling, and prevents the workpiece from floating up from between the two mouthpieces.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view showing the main parts of the long object processing vise of the present invention. A fixed wall 3 and a movable wall 4 are provided on the upper surface of the base 2 (FIGS. 4 and 5) so as to be movable toward and away from each other.
Caps 9, 9 made of carbon steel or stainless steel and having the same shape are fixed to the inner surfaces of the caps 9 and 9 facing each other. Each cap 9, 9 has a straight portion 10 located inside the inner surface of the fixed wall 3 or movable wall 4, and an inclined portion extending from both ends of this straight portion 10 and protruding from the inside of each wall 3, 4. Part 11, 11
The total length of each cap 9, 9 is 500 mm as shown in Fig. 2, and the length _L1 of the straight part 10 in the center is the same as the width of each wall 3, 4.
200mm, and the length L ₂ of the sloped parts at both ends is
It is set to 150mm. Inclined portion 11 of each cap 9, 9,
11 are both inclined in such a direction that the distance becomes narrower toward the ends of the bases 9, 9, but in the case of the embodiment, the straight line a connecting both outer ends of the inclined parts 11, 11 and the straight line part 10 The distance δ from the face of the plane is set to 0.3 mm.

As shown in FIG. 3, each of the caps 9, 9 has an upper thickness T of 22.003 mm, a lower thickness t of 22.000 mm, and a height H of 53 mm. Therefore, the distance between the caps 9, 9 is wider as it goes downward, and becomes narrower gradually as it goes upward.

Furthermore, the inclined portions 11, 11 at both ends of each cap 9, 9
By forming recesses 12, 12 that gradually become deeper toward the ends on the rear surface, each inclined portion 1
The thicknesses of 1 and 11 are made smaller toward the ends. However, both ends 13, 13 of each cap 9, 9
Only the straight portions 10 and 10 have the same thickness. This is the back surface of both ends 13, 13 and the straight portions 10, 10.
By locating the rear and back surfaces of the caps on the same plane, the front surfaces of the respective caps 9, 9 can serve as reference surfaces when machining the shapes shown in FIGS. 2 and 3.

The caps 9, 9 processed into such a shape can be fixed by fixing the rear back surface of each linear portion 10, 10 to the mutually opposing surfaces of the fixed wall 3 or the movable wall 4, as shown in FIG. The work piece is held between the two mouthpieces 9, 9 as shown in FIG.

c. Effects of the invention The long workpiece processing vise of the present invention is constructed and operates as described above, but the long workpiece can be firmly held between the elastic mouthpieces.
Long objects can be processed efficiently.
