The engraving vise includes a fixed base, a movable support mounted on the fixed base, a rotary support that is rotatably supported by the movable support, and a pair of clampers that sandwich a workpiece and that are close to each other. It consists of

  When an operator processes a workpiece material using the engraving vise, first, the operator holds the workpiece material with a pair of clampers. Then, the operator rotates the movable support body in the plane direction and the side surface direction or rotates the rotation support body with respect to the fixed base so as to easily process the workpiece material.

JP-A-4-69172

In the engraving vise described in Patent Document 1, since the movable support is formed in a hemispherical shape, the diameter of the movable support increases as it goes upward from the fixed base side. For this reason, when the operator rotates the movable support in the plane direction and the side direction with respect to the fixed base, it is necessary to operate the spherical surface of the movable support with both hands, and the rotation support is performed while rotating the movable support. There is a problem that it is difficult to operate the body and the operation is not easy.
The engraving vise includes a selection mechanism that switches the rotation support to a rotatable state or a state in which rotation is restricted. For this reason, when rotating a rotation support body, it is necessary to operate a selection mechanism, and there also exists a problem that operation is troublesome. In addition, depending on the position of the selection mechanism, when the movable support is rotated in the lateral direction, the selection mechanism comes into contact with the fixed base, the rotation range of the movable support is limited, and workability is deteriorated. is there.

  An object of the present invention is to provide a jig that can be easily operated and can improve workability.

  The jig of the present invention is a jig for placing a workpiece when processing the workpiece, and the pedestal portion substantially along the extending direction of the outer surface of the pedestal portion and a pedestal portion formed in a column shape A movable portion having an outer surface formed so as to be substantially flush with an outer surface of the pedestal, and provided rotatably on the pedestal portion about the axial direction of the pedestal portion, and provided rotatably on the movable portion. And a movable part that is substantially orthogonal to the axial direction on the other end side, and has a bottom surface that intersects with the axial direction at an angle other than 90 degrees. A side contact surface is formed, and the movable portion intersects the first contact surface contacting the movable portion side contact surface with the axial direction at an angle other than 90 degrees, and with respect to the workpiece fixing portion. A second contact surface is formed, and the work fixing portion is in contact with the second contact surface. A workpiece contact surface and a workpiece placement surface on which the workpiece is placed, and the pedestal portion, the movable portion, and the workpiece fixing portion are configured to have a size that can be gripped simultaneously with one hand. Features.

According to the present invention, the jig is composed of a pedestal part, a movable part, and a work fixing part, and each part is formed in a size that allows an operator to simultaneously hold it with one hand. Thereby, a jig | tool can be reduced in size with a simple structure.
Further, in the present invention, since the selection mechanism for switching each part to a freely rotatable state or a state for restricting the rotation as described above is not provided, the troublesome operation of the selection mechanism is eliminated, and the operability is improved. it can. As a result, the range of rotation of each part is not limited, and workability can be improved.
Further, the movable portion rotates around the axial direction of the pedestal portion and has an outer surface that is substantially flush with the outer surface substantially along the outer surface of the pedestal portion. Thus, the operator can easily grip the outer surfaces of the pedestal portion and the movable portion simultaneously with one hand, and can easily operate the gripper while rotating the movable portion while gripping the pedestal portion. In addition, since the workpiece fixing portion is provided so as to be rotatable with respect to the movable portion, the operator can rotate the workpiece fixing portion while rotating the movable portion while holding each portion with one hand. Can be operated easily. Therefore, the operator can hold and operate the jig with one hand and can work the workpiece with a tool or the like with the other hand, thereby improving workability.

  In the present invention, the bottom surface formed on one end side of the pedestal portion (for example, the surface facing the mounting surface of the work table) intersects the axial direction of the pedestal portion at an angle other than 90 degrees. When the is placed on the work table, the axial direction of the pedestal and the placement surface of the work table intersect at an angle other than 90 degrees. That is, since the pedestal portion is disposed to be inclined with respect to the mounting surface of the work table, the operator can easily grasp the pedestal portion without changing the direction of the hand. Furthermore, since the movable part rotates around the axial direction of the pedestal part, the operator rotates the movable part around the axial direction of the pedestal part without changing the direction of the hand while holding the pedestal part with one hand. Can be operated easily.

Here, for example, when the second contact surface is formed so as to be orthogonal to the axial direction of the pedestal portion, when the movable portion is rotated around the axial direction of the pedestal portion, the second contact surface is It will rotate only within a plane that intersects the mounting surface at a certain angle. In this case, when machining the workpiece, even if the movable part is rotated, the workpiece machining surface can be rotated only within one plane, and the workpiece machining surface is oriented in the direction desired by the operator. It cannot be turned, and workability is not improved.
Therefore, in the present invention, the second contact surface of the movable part intersects with the axis direction of the pedestal part at an angle other than 90 degrees, so when the movable part is rotated around the axial direction of the pedestal part, The two contact surfaces are positioned on surfaces that intersect at various angles with respect to the mounting surface of the work table. Furthermore, since the workpiece fixing portion is also provided so as to be rotatable with respect to the movable portion, the workpiece fixing portion can be rotated 360 degrees with respect to the movable portion. Thereby, when an operator processes a workpiece, the processing surface of the workpiece can be directed in a desired direction, and workability is improved.

  In the present invention, it is preferable that the sum of the angle intersecting the bottom surface and the movable part side contact surface and the angle intersecting the first contact surface and the second contact surface is approximately 90 degrees.

  In the present invention, it is possible to set a state in which the bottom surface and the second contact surface are substantially parallel. That is, it is possible to set a state in which the second contact surface is substantially parallel to the mounting surface of the work table, and the work surface of the workpiece is also substantially parallel to the mounting surface of the work table. For this reason, the operator can directly view the work surface of the workpiece, and the workability is further improved.

  In the present invention, a first shaft portion that protrudes in a direction orthogonal to the movable portion side contact surface and the first contact surface is formed on either the movable portion side contact surface or the first contact surface. A first hole portion into which the first shaft portion is inserted is formed on one of the other, and either the second contact surface or the workpiece contact surface includes the second contact surface and the workpiece contact surface. A second shaft portion that protrudes in a direction orthogonal to the first shaft portion is formed, and a second hole portion into which the second shaft portion is inserted is formed on one of the other, and the movable portion is centered on the first shaft portion. It is preferable that the work fixing portion rotates about the second shaft portion.

  In the present invention, the movable portion rotates about the first shaft portion with respect to the pedestal portion, and the work fixing portion rotates about the second shaft portion with respect to the movable portion. According to this, since an operator should just rotate a movable part and a workpiece | work fixing | fixed part centering on a 1st axial part and a 2nd axial part, operativity improves more.

  In this invention, it is preferable that the said base part is formed in the substantially column shape.

  In the present invention, since the pedestal portion is formed in a substantially cylindrical shape, an operator can easily grip the pedestal portion. Furthermore, the movable part formed substantially flush with the outer surface of the pedestal part can be easily grasped, and the operator can easily grasp the jig, thereby making the operability easier.

  In the present invention, a first positioning protrusion that protrudes in a direction perpendicular to the movable part side contact surface and the first contact surface is formed on either the movable part side contact surface or the first contact surface. In the other, a plurality of first positioning holes into which the first positioning protrusions are fitted are formed, and either the second contact surface or the workpiece contact surface includes the second contact surface and A second positioning protrusion that protrudes in a direction orthogonal to the workpiece contact surface is formed, and a plurality of second positioning holes into which the second positioning protrusion is fitted are formed on either one of the second positioning protrusion, The movable part is positioned by fitting the first positioning protrusion and the first positioning hole, and the movable part and the workpiece fixing part are the second positioning protrusion and the second positioning hole. Mating Positioning are preferably.

In the present invention, the pedestal portion and the movable portion are fixed by fitting the first positioning protrusion and the first positioning hole. Further, the movable part and the work fixing part are fixed by fitting the second positioning protrusion and the second positioning hole.
Therefore, it is possible to prevent the positional deviation between the pedestal part and the movable part and the positional deviation between the movable part and the workpiece fixing part during the work processing of the workpiece, and the workability can be further improved.

[Schematic configuration of jig]
FIG. 1 is an exploded perspective view of the jig 1 according to this embodiment, and FIG. 2 is a cross-sectional view of the jig 1.
The jig 1 is used, for example, when performing a processing operation such as processing or decoration on a small work such as a watch case. For this reason, the jig 1 is configured to be a size that allows the operator to hold the whole with one hand and is small, so that the jig 1 can be freely moved on a mounting surface such as a work table.
The jig 1 includes a pedestal part 2, a movable part 3, and a work fixing part 4. In addition, since the jig | tool 1 should just change the workpiece fixing | fixed part 4 according to the shape of a workpiece | work, it is not limited to processing of a watch case, It can be used for processing of various workpieces. .

[Configuration of pedestal]
The pedestal portion 2 is formed in a substantially cylindrical shape, and a bottom surface 21 that intersects with the axial direction A of the pedestal portion 2 (dashed line in FIG. 2) at an angle of approximately 45 degrees is formed on one end side. Further, on the other end side of the pedestal portion 2, a movable portion side contact surface 22 that is substantially orthogonal to the axial direction A and that contacts the movable portion 3 is formed.
The bottom surface 21 is, for example, a portion that is placed on a placement surface such as a work table.
The movable portion side contact surface 22 is formed in a substantially circular shape, and includes a first shaft portion 221 formed along the axial direction A.
Moreover, as the surface roughness of the movable part side contact surface 22, when the movable part 3 rotates with respect to the pedestal part 2, or during the processing operation, the movable part 3 comes off from the pedestal part 2 or slips too much. It is set to such an extent that the movable part 3 is slippery when the movable part 3 is rotated with respect to the base part 2. Specifically, the surface roughness of the movable portion side contact surface 22, the maximum height R _Z defined by JIS B0601-2001 is set to be 6.3 [mu] m.
An angle θ ₁ formed by the bottom surface 21 of the first pedestal portion 2 and the movable portion side contact surface 22 is approximately 45 degrees.

[Configuration of moving parts]
The movable part 3 includes a first contact surface 31 that contacts the movable part side contact surface 22 of the pedestal part 2 and a second contact surface 32 that contacts the workpiece fixing part 4. An outer surface 33 that is substantially flush with the outer peripheral surface of the pedestal portion 2 is formed on a part of the outer surface of the movable portion 3 along the extending direction of the outer peripheral surface of the pedestal portion 2. The outer surface 33 is formed so that the operator can easily rotate the movable portion 3 while holding the pedestal portion 2 with one hand, and improves the operability of the operator.

The first contact surface 31 is orthogonal to the axial direction A of the pedestal portion 2, is formed in a substantially circular shape, and has a diameter that is substantially the same as that of the movable portion side contact surface 22. As shown in FIG. 2, the first contact surface 31 is formed with a first hole portion 311 into which the first shaft portion 221 of the pedestal portion 2 is inserted.
Further, the surface roughness of the first contact surface 31 is set so that the maximum height R _Z is 6.3 μm, similarly to the surface roughness of the movable portion side contact surface 22.
A clearance is provided between the first shaft portion 221 and the first hole portion 311. Specifically, the dimensional difference between the outer diameter of the first shaft portion 221 and the inner diameter of the first hole 311 is set so as not to be less than 25 μm. As a result, the movable portion 3 rotates 360 degrees around the axial direction A in the direction of the arrow B1 (see FIG. 3). That is, the first contact surface 31 rotates 360 degrees around the axial direction A while being in contact with the movable portion side contact surface 22 within the plane of the movable portion side contact surface 22.

A second shaft portion 321 is formed on the second contact surface 32 along the vertical direction.
Further, as the surface roughness of the second contact surface 32, when the work fixing part 4 is rotated with respect to the movable part 3 or during a machining operation, the work fixing part 4 is detached from the movable part 3 or slips. It is set so as not to be too much and to be slippery when the work fixing part 4 is rotated with respect to the movable part 3. Specifically, the surface roughness of the second contact surface 32, the maximum height R _Z is set to be 6.3 [mu] m.
The second contact surface 32 and the axial direction A of the pedestal portion 2 intersect at an angle of approximately 45 degrees. Then, the angle theta ₂ formed by the first contact surface 31 and second contact surface 32 has a substantially 45 degrees. The sum of the angle θ ₁ formed by the bottom surface 21 of the first pedestal 2 and the movable portion side contact surface 22 and the angle θ ₂ formed by the first contact surface 31 and the second contact surface 32 is approximately 90 degrees. The 2nd contact surface 32 is formed so that it may become. Thereby, the bottom surface 21 and the second contact surface 32 can be set in a substantially parallel state, and the second contact surface 32 can be set in a substantially parallel state with a mounting surface such as a work table.
When the movable part 3 rotates about the axial direction A in the direction of the arrow B1 (see FIG. 3), the second contact surface 32 is positioned on a surface that intersects various angles with respect to the work table mounting surface. It becomes possible.

[Configuration of work fixing part]
The workpiece fixing unit 4 includes a workpiece contact surface 41 that comes into contact with the second contact surface 32 of the movable unit 3 and a workpiece placement surface 42 on which the workpiece is placed. The workpiece fixing unit 4 is appropriately selected by the operator according to the shape of the workpiece.
As shown in FIG. 2, the work contact surface 41 is formed with a second hole portion 411 into which the second shaft portion 321 of the movable portion 3 is inserted. As the surface roughness of the workpiece contact surface 41, similarly to the surface roughness of the second contact surface 32, the maximum height R _Z is set to be 6.3 [mu] m.
Similarly, a clearance having the above-described dimensional difference is provided between the second shaft portion 321 and the second hole portion 411. Thereby, the workpiece fixing unit 4 rotates 360 degrees with respect to the movable unit 3 about the second shaft portion 321 in the direction of the arrow B2 (see FIG. 3). That is, the workpiece contact surface 41 rotates 360 degrees around the second shaft portion 321 and in contact with the second contact surface 32 within the surface of the second contact surface 32. Accordingly, the workpiece placed on the workpiece placement surface 42 is rotated 360 degrees in the direction of the arrow B2 (see FIG. 3) around the second shaft portion 321 together with the workpiece fixing portion 4. .
The workpiece placement surface 42 is a portion on which the workpiece is placed. In this embodiment, the watch case is placed, and thus the center of the watch case is bulged so that the frame portion of the watch case can be easily placed. It has become.

[Jig operation]
Next, the operation of the jig 1 will be described with reference to FIGS.
First, the worker places the work on the work placement surface 42 of the work fixing unit 4. At this time, as shown in FIG. 3, the workpiece placement surface 42 is horizontal with respect to the placement surface of the work table.
Then, the operator operates the jig 1 by gripping the jig 1 with one hand in order to direct the processed surface of the workpiece in a direction in which the workpiece is easily processed.
For example, in order to rotate the movable part 3 from the state of FIG. 3 to the state of FIG. 4, the operator operates the outer surface 33 of the movable part 3 while holding the pedestal part 2 with one hand. Is rotated 90 degrees about the axial direction A (see FIG. 2) in the direction of the arrow B1. Thereby, as shown in FIG. 4, the workpiece mounting surface 42 is perpendicular to the mounting surface of the work table.
Further, the work fixing part 4 also rotates the work fixing part 4 from 0 degrees to 360 degrees around the second shaft part 321 (see FIGS. 1 and 2) in a direction in which the work surface of the work can be easily machined as required. Let

The jig 1 according to the first embodiment described above has the following effects.
According to the present embodiment, the jig 1 includes a pedestal part 2, a movable part 3, and a work fixing part 4, and each part 2 to 4 is formed in a size that allows an operator to simultaneously hold with one hand. . Thereby, the jig | tool 1 can be reduced in size with a simple structure.
Moreover, in this embodiment, since the selection mechanism which switches each part 2-4 to the state which can rotate freely as mentioned above or the state which controls rotation is not provided, the troublesomeness which operates a selection mechanism is lost, Operability can be improved. As a result, the range of rotation of each part 2 to 4 is not limited, and workability can be improved.
Further, the movable portion 3 rotates around the axial direction A of the pedestal portion 2 and has an outer surface 33 that is substantially flush with the outer surface substantially along the outer surface of the pedestal portion 2. Thus, the operator can easily grip the outer surfaces of the pedestal portion 2 and the movable portion 3 simultaneously with one hand, and can easily operate the grip portion 2 while rotating the movable portion 3. Furthermore, since the workpiece fixing portion 4 is provided so as to be rotatable with respect to the movable portion 3, the operator can fix the workpiece while rotating the movable portion 3 while holding each portion 2 to 4 with one hand. The part 4 can also be rotated, and the operability is improved. Therefore, the operator can hold and operate the jig 1 with one hand, and can work the workpiece with a tool or the like with the other hand, thereby improving workability.

  Further, since the bottom surface 21 formed on one end side of the pedestal part 2 intersects the axial direction A of the pedestal part 2 at an angle of about 45 degrees, when the pedestal part 2 is placed on the work table, It will intersect the mounting surface of the work table at an angle of approximately 45 degrees. That is, since the pedestal part 2 is disposed to be inclined with respect to the mounting surface of the work table, the operator can easily grasp the pedestal part 2 without changing the direction of the hand. Furthermore, since the movable part 3 rotates around the axial direction A, the operator rotates the movable part 3 around the axial direction A without changing the direction of the hand while holding the pedestal part 2 with one hand. Can be operated easily.

  Further, since the second contact surface 32 intersects with the axial direction A of the pedestal portion 2 at an angle of approximately 45 degrees, the second contact surface 32 can be obtained by rotating the movable portion 3 around the axial direction A of the pedestal portion 2. The contact surface 32 is positioned on a surface that intersects at various angles with respect to the mounting surface of the work table. Furthermore, since the workpiece fixing portion 4 is also provided so as to be rotatable with respect to the movable portion 3, the workpiece fixing portion 4 can be rotated 360 degrees within the surface of the second contact surface 32. Thereby, the operator can orient the processing surface of the workpiece in a desired direction, and workability is improved.

Further, the bottom surface 21 and the second contact surface 32 can be set in a substantially parallel state. That is, since the second contact surface 32 is substantially parallel to the work table mounting surface, the workpiece processing surface can be set to be substantially parallel to the work table mounting surface. For this reason, the operator can directly view the work surface of the workpiece, and the workability is further improved.
Further, the movable portion 3 rotates about the first shaft portion 221 with respect to the pedestal portion 2, and the workpiece fixing portion 4 rotates about the second shaft portion 321 with respect to the movable portion 3. According to this, since an operator should just rotate the movable part 3 and the workpiece | work fixing | fixed part 4 centering on the 1st axial part 221 and the 2nd axial part 321, operativity improves more.
Further, since the pedestal portion 2 is formed in a substantially cylindrical shape, an operator can easily grip the pedestal portion 2. Furthermore, the movable part 3 formed substantially flush with the outer surface of the pedestal part 2 can be easily grasped, so that the operator can grasp the jig 1 more easily and the operability is further improved.
