Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a vice that can fix a tapered object.

(Prior art and its problems) A movable member is screwed onto a threaded rod protruding from a fixed member, and by rotating the threaded rod, the movable member is moved back and forth relative to the fixed member to clamp and fix an object. In conventional vises configured to do this, the clamping surfaces of the stationary member and the movable member were always parallel, so objects whose clamping surfaces were not parallel to each other could not be properly clamped.

(Means for solving the problem) This invention was made in view of the above circumstances.
It is an object of the present invention to provide a vice capable of clamping and fixing an object having surfaces that are not parallel to each other, such as a tapered portion, on its outer surface.

That is, the vise according to the present invention has a guide screw formed on the outer periphery of the front part, and the rear part is screwed into the shaft serving as the base and the guide screw of the shaft, and can be moved back and forth in the axial direction by rotation of the shaft. A vice comprising a movable member that is movably supported, and a fixed position member that is provided at the base of the shaft and is fitted to the shaft so that the shaft can freely rotate,
The movable member and the fixed position member are both rotatably supported around a protrusion perpendicular to the axis, and the mutually opposing surfaces of both members are formed as clamping surfaces for clamping the article. There is.

(Embodiment) The embodiment shown in the drawings will be described below. FIGS. 1 to 3 show an example of a vice according to the present invention.
The shaft 3 is provided with a fixed position member 4 and a moving member 5, which are provided facing each other.

The shaft 3 consists of a smooth cylindrical base 3a and a threaded portion 3b having a guide screw 7 formed on its outer periphery, and a grip 8 is integrally attached to the rear end of the base 3a.

The fixed position member 4 and the movable member 5 respectively connect upper members 4a, 5a and lower members 4b, 5b with screws 9,
It is combined with 9,... Square through holes 10, 10 are provided in the central parts of the lower members 4b, 5b, and the intermediate parts are constricted and the front and rear parts of the holes are gradually widened. is fitted. Concentric circular holes 11a, 11b, 12a, 12b are bored above and below the center of the intermediate members 11, 12, and circular protrusions 4c, 4d, 5c, 5d of the upper members 4a, 5a and the lower members 4b, 5b are inserted into these holes. It is inserted so that it can rotate freely. Therefore, the fixed position member 4 and the moving member 5 have circular protrusions 4c, 4d,
5c and 5d are respectively pivotably supported relative to the intermediate members 11 and 12 within the lap-like opening range of the through hole 10. The intermediate member 11 of the fixed position member 4 has a circular hole 16 which is a smooth through hole, and the base portion 3a of the shaft 3 is rotatably inserted through the circular hole 16. Note that the intermediate material 11 is inserted into the locking groove 17 of the base 3a.
Since the locking edges 18 of the fixed position member 4 are engaged with each other, the fixed position member 4
does not move in the axial direction. On the other hand, the intermediate material 12 of the moving member 5 has a screw hole 19, and the shaft 3 is inserted into the screw hole 19.
The threaded portions 3b are screwed together.

The surfaces of the fixed position member 4 and the movable member 5 that face each other serve as clamping surfaces 21 and 21', and a stepped portion 22 is formed at the upper part, and grooves 23a and 23b each having a V-shaped cross section are provided in the vertical and horizontal directions. It is being Further, a plurality of vertical holes 24, 24, . . . are provided on the upper surface of the upper members 4a, 5a on the clamping surface side. Of these, a pair of vertical holes 24, A are connected to the screw 9.
Also serves as the insertion hole. Furthermore, upper members 4a, 5
a and near the lower ends of both sides of the lower members 4b and 5b,
Axial guide holes 25a and 25b are bored. In Figures 1 to 3, the guide hole 25
Guide rod 2 with a bulge 26a on a and 25a
6 is inserted.

A method of using this vice 1 will be described below using drawings illustrating usage examples.

FIG. 4 shows a method for fixing an object such as a rectangular parallelepiped whose surfaces are parallel to each other. In this case, it is convenient if the guide rod 26 is provided to pass through the guide hole 25a or 25b of the fixed position member 4 and the moving member 5. First, the fixed position member 4 and the movable member 5 are maintained at an appropriate interval, and the object 30 to be fixed is inserted into this interval. Next, when the grip 8 is rotated in a predetermined direction (rightward in the illustrated example), the shaft 3 freely rotates with respect to the fixed position member 4, but with respect to the movable member 5, it rotates freely through the screw hole of the intermediate member 12. 19 and threaded part 3
As a result, the movable member 5
, and narrow the width of the gap. Further, when the grip 8 is rotated, both members 4 and 5 approach each other, and as shown in the figure, the respective clamping surfaces 21 and 2
1' to firmly fix the object 30. At this time, if the guide rod 26 is inserted into the guide hole 25a or 25b, the clamping surfaces of both members 4 and 5
1, 21' are always kept parallel, and both members 4,
5 does not rotate around the shaft 3, the fixing operation is simple and the object 30 to be fixed can be held securely.

In addition, the lower guide hole 25b is used to attach the vise 1 to the workbench 33 using a shiyako vise type clamp 33.
It can also be used when installing the

Next, FIG. 5 shows a method of fixing a tapered object, and in this case no guide rod is used.
Fixation is performed by following the same steps as above, but since the fixed position member 4 and the movable member 5 are not connected by the guide rod, both members 4 and 5 are individually oscillated relative to the shaft 3. It can be rotated. Therefore, as the grip 8 is tightened, the members 4, 5 rotate so that the clamping surfaces 21, 21' are along the surface of the object 30'. Therefore, even tapered objects can be securely fixed with high adhesion. Note that the amount of left and right rotation of the fixed position member 4 and the movable member 5 is regulated within the range of the ripple-shaped expansion of the through hole 10, so that these can be rotated unnecessarily without providing a special stopper. It is convenient to handle.

FIG. 6 shows a method for fixing objects whose surfaces are not flat. For objects whose surfaces are not flat, such as the elliptical object shown in the illustration, the clamping surfaces 21 and 2 are flat.
1' cannot hold it properly. Therefore,
By pushing the auxiliary rod 36 into the vertical holes 24 of the fixed position member 4 and the moving member 5, the upper part of the auxiliary rod 36 is made to project upward, and the object to be fixed 30'' is held between the auxiliary rods 36, 36. By doing this, it is possible to successfully fix objects whose surfaces are not flat.Of course, it is possible to fix objects with various shapes other than the elliptical cross section as shown in the example shown.
If three auxiliary rods 36 are installed in appropriate vertical holes 24 to support the object at three points, objects with even more complex shapes can be fixed. In addition, thin sticks etc.
V-shaped groove 23 provided in the clamping surfaces 21, 21'
By fixing a part of the object to be fixed in a state where it is engaged with a and 23b, the object to be fixed can be securely fixed without shifting.

The above usage examples only illustrate some of the uses of this vise, and by using jigs and the like other than the illustrated examples, the vise can be used for a wider range of uses.

(Effects of the Invention) As is clear from the above description, the vise according to the present invention can be carried by gripping the grip, and can also be carried while an article is positioned between the fixed position member and the moving member. By rotating the grip around the axis to move the movable member, the present invention has become excellent in that it is possible to clamp and fix articles whose clamping surfaces are not parallel, such as articles having tapered outer surfaces, with a simple operation. Furthermore, since the fixed position member and the movable member are supported by one common shaft, this vise is easy to handle, functional, and structurally compact.
