[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a jig that is used to hold a work during work such as grinding (eg grinding) of the work, and more specifically, machining of parts such as dies, particularly multifaceted / multivariable where high precision is required. The present invention relates to a jig used for processing (for example, grinding) a corner work.

[0002]

[Prior art]

 Conventionally, in the processing of parts such as a mold, when the four corners of the processed portion Wa of the upper end portion of the work W as shown in FIG. 5 (a) are subjected to grinding processing with different angles as shown in FIG. 5 (b). Then, the mass type jig 5 as shown in FIG. 6, the magnet block 6 for fixing the mass type jig 5, the sign bar 7 on which the mass type jig 5 is placed, and the sign bar 7 are tilted. A block gauge 8 was used to hold it obliquely.

When the work W is processed into a shape as shown in FIG. 5B, for example, the four corners of the processed portion Wa of the work W as shown in FIG. 7 are arranged in the order of C1 to C4, for example. It is to grind. In this case, in order to grind the first corner C1, as shown in FIG. 8, a block gauge 8 for tilting the work W at a predetermined angle is placed on the table T of the grinder. , The sign bar 7 is installed so as to be inclined. Then, the mass type jig 5 on which the work W is set is set on the sign bar 7, and the mass type jig 5 is attracted and fixed by the magnet block 6.

After that, as shown in FIG. 9, the first corner C1 is ground with a grindstone 9.

Next, in order to grind the second corner C2, the first corner block gage 8 is removed. Then, the block gauge 8 corresponding to the second corner portion C2 is placed under the sine bar 7, the inclination angle of the sine bar 7 is changed, and then the table T is moved, as shown in FIG. 9 is placed in the second corner C2 grinding position. Then, the grindstone 9 is driven to grind the second corner C2.

Next, the third and fourth corners C3 and C4 are ground. This is because by installing a block gauge on the side opposite to where the block gauge 8 for forming the first surface corner C1 was installed, the sign bar 7 was tilted to the opposite side, and after this, The third corner C3 and the fourth corner C4 are ground in the same procedure as described above.

[Problems to be solved by the device]

 By the way, the workpiece is held at a predetermined angle by using the components such as jigs and cymbals arranged on the table as described above, and processed into the multi-sided / multi-variable angle as shown in Fig. 5. In order to carry out the work, the setting of the work (changing the working direction) had to be redone every time one-side machining was performed, and the work efficiency was extremely poor in setup work.

Therefore, the object of the present invention is to perform multifaceted and / or multivariable angle machining with a single work setting, and in such machining, setup work can be reduced and work efficiency can be improved. It is to provide a jig that can be used for a good grinder or the like.

[0009]

[Means for Solving the Problems]

 According to the present invention, a reference member having a jig reference surface, an oscillating body having an intermediate pivot point pivotally supported by the reference member, and a block gauge detachably attached to the jig reference surface, The universal jig is characterized in that the oscillating body has a contact portion that is located on both sides of the fulcrum and abuts against the block gauge when oscillating, and a chuck portion that contributes to holding a work. The ingredients are obtained.

[0010]

According to this universal jig, since the rocking body is pivotally supported so as to be capable of rocking to the left and right so as to change the relative angle with respect to the reference member, the space between the rocking body and the jig reference plane is set. The work can be set and held at any inclination angle simply by setting the block gauge on.

[0011]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, a universal jig according to an embodiment of the present invention is composed of a bottom plate 1, side plates 2 and an oscillating body 3. A reference surface 11 is formed on the upper surface of the bottom plate 1 so as to be flush. A side plate 2 is erected on the reference surface 11 in a direction at a right angle. The bottom plate 1 and the side plate 2 together form a reference member.

On one surface side of the side plate 3 and on the reference surface side of the bottom plate 1, a rocking body 3 is rockably mounted. That is, the oscillating body 3 is rotatably supported by a shaft 30 formed at a predetermined position on the lower end of the oscillating body 3 in the right-left direction (the direction orthogonal to the grinding wheel) so as to project from the side plate 2 in the right-angle direction. , Can be swung in the left-right direction. Chuck portions 31 and 33 are formed on the upper surface of the oscillator 3 and the side surface on the reference surface 11 side (the side facing the grinding wheel).

Next, a description will be given of a process of holding a workpiece, which is an object to be processed, in the chuck portions 31 and 33, and setting the work on a table T of a grinding machine as shown in FIG. 2 for processing, for example. In the following description, an example will be described in which the processed shape of the work is processed into a shape similar to that described in the conventional art.

First, the work W is held by the chuck portion 33 on the side surface side of the side plate rocking body 3. Then, the corners of the work W shown in FIG. 8 are ground in the order of C1 to C4.

In the grinding process of the first corner portion C1, as shown in FIG. 3, the first corner portion C1 is grounded between the block gauge contact portion 35 on the left side of the oscillator 3 and the bottom plate 1 reference surface 11. Corner C1 A block gauge B1 for grinding is interposed. Then, the oscillating body 3 is set to the chamfering inclination angle of the first corner C1 of the work W. In this state, the first corner C1 is ground with the rotary grindstone 9.

Next, in the grinding of the second corner C2, the first block gauge B1 is removed and replaced with a second block gauge B2 for grinding the second corner C2. Then, the oscillating body 3 is set to the chamfering inclination angle of the second corner portion C2 of the work W. In this state, the rotary grindstone 9 is used to grind the second corner C2.

Next, in the grinding process of the third corner C3, as shown in FIG. 4, the oscillating body 3 is rotated to the opposite side so that the block gauge contact portion 37 on the right side of the oscillating body 3 is A third block gauge B3 for grinding a third corner C3 is interposed between the bottom plate 1 and the reference surface 11. Then, the oscillating body 3 is set to the chamfering inclination angle of the third corner portion C3 of the work W. In this state, the third corner C3 is ground with the rotary grindstone 9.

Next, in the grinding process of the fourth corner C4, the third block gauge B3 is removed and replaced with the fourth block gauge B4 to grind the fourth corner C4. . Then, the oscillating body 3 is set to the chamfering inclination angle of the fourth corner portion C4 of the work W. In this state, the fourth corner C4 is ground with the rotary grindstone 9.

[Effect of device]

 As described above, according to the jig of the present invention, the jig functions as a universal swing and the swing body has a sine bar function, so that an arbitrary angle can be machined on many sides of the workpiece. In this case, each surface can be processed by setting the work once, and as a result, it is possible to significantly improve the work efficiency by reducing the number of setup man-hours.
