Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is assembled into processing equipment such as a drilling machine to accurately determine and maintain the tilted posture of a workpiece such as a mold block at a desired tilt angle. This relates to an indexing device.

[Conventional technology]

In processing equipment such as drilling machines, a workpiece such as a mold block is strongly clamped and fixed on the processing table by a vise, and the processing machine performs processing such as drilling a desired hole.
The processing table installed in the main body of the processing equipment is configured to hold the workpiece in a horizontal position, so special measures must be taken when processing the workpiece at a certain angle of inclination. Ta.

Conventional means for machining the workpiece at a desired angle include means for tilting the processing machine 8 itself shown in FIG. 12, and means for using the indexing machine 9 shown in FIG. be.

The means for tilting the processing machine 8 shown in FIG.
The machining angle is determined by rotating and tilting the machining machine 8 together with its guide means by a desired inclination angle with respect to the support frame assembled to the machining table 6.

Further, the means for using the indexing machine 9 shown in FIG. The table of the indexing machine 9 on which is fixed is tilted at a desired angle to achieve indexing of the machining angle.

[Problem to be solved by the invention]

In the case of the prior art shown in FIG. 12, since the entire processing machine 8 needs to be rotated, the assembly of the processing machine 8 to the processing table 6 becomes complicated, and the accurate indexing of the processing machine 8 is difficult. There is also the problem that maintaining this calculated inclination angle is troublesome and likely to be difficult.Furthermore, due to the rotational inclination of the processing machine 8, the position of the processing function part at the tip of the processing machine 8 with respect to the surface of the processing table 6 may shift. However, there is a problem in that it becomes troublesome to accurately locate the shifted machining position 1.

Furthermore, in the case of the prior art shown in FIG. 13, since a dedicated indexing machine 9 is used, there is no inconvenience of changing the processing equipment. Since it is necessary to assemble the indexing machine 9 to the processing equipment, it is troublesome to attach and detach the indexing machine 9 to the processing equipment, it is impossible to assemble it to small processing equipment, and the equipment cost required for the indexing equipment increases. There's a problem.

Therefore, the present invention was devised to solve the above-mentioned problems in the conventional technology.The present invention utilizes the vise installed in the processing equipment as it is, and uses the vise to index the workpiece to a desired inclination angle and clamp and fix the workpiece. The purpose of this invention is to provide an indexing device that is convenient to handle and inexpensive.

[Means for Solving the Problems] The means of the present invention for solving the above problems is an indexing device that clamps and holds a workpiece in a vise of processing equipment at a desired inclination angle posture; A flat plate that is immovably assembled on the front, has a fulcrum hole on the front facing the other vise piece, and has multiple setting holes equally spaced on a circumference of a constant radius around this fulcrum hole. At one end of the flat body part, the upper surface is a flat workpiece mounting surface, and the length is greater than the distance between the fulcrum hole and the setting hole, and the width is smaller than the workpiece. , The pivot assembly to the fulcrum hole must have a cradle with a shaft hole formed as a part, and a cylindrical column that is fitted and assembled into the selected setting hole and protrudes from inside this setting hole to the front of the installation plate. The support part has a positioning pin for mounting and supporting the other end of the pedestal that is pivotally assembled to the installation plate.

A plurality of setting holes are provided for the fulcrum hole, but the form of the positional relationship between the fulcrum hole and the setting hole is not specified to one form, and multiple setting holes are arranged around one fulcrum hole. The setting holes may be arranged at equal intervals on a single circumference, or a plurality of setting holes may be arranged at equal intervals on a plurality of circumferences centered on one fulcrum hole, and even more A plurality of setting holes may be provided close to each other, and a plurality of setting holes may be provided at equal intervals on a single circumference centered on each fulcrum hole.

Further, in order to determine the angle between the angles determined by adjacent setting holes, it is preferable to provide a plurality of positioning pins whose support portions have different diameters in stages.

Further, in order to stabilize the placement of the workpiece on the workpiece mounting surface, it is preferable that the cradle is configured with a locking piece protruding from the upper surface of the other end of the main body.

[Effect]

When assembling the indexing device according to the present invention to processing equipment, an installation plate is installed and fixed in front of one vise piece of the vise of the processing equipment, and a pedestal is pivotally fixed to this installation plate at its shaft hole. At the same time, this is accomplished by fitting and assembling a positioning pin into the selected setting hole and placing the other end of the pedestal on the support of the positioning pin.

In this way, once the indexing device according to the present invention has been assembled into the vise, a workpiece is mounted on the workpiece mounting surface of the cradle to achieve indexing of the workpiece,
The workpiece is firmly clamped and held in a vise and the specified processing is performed. At this time, since the workpiece is wider than the pedestal, the vice can clamp the workpiece without being obstructed by the pedestal.

The indexing of the workpiece in the indexing device according to the present invention is achieved by changing and setting the inclination angle of the workpiece mounting surface of the cradle, which is pivotally attached to the installation plate so as to be rotatable about the fulcrum hole. Setting the inclination angle of the workpiece mounting surface is achieved by which setting hole the positioning pin is assembled into.

In other words, since the setting holes are arranged on the front of the installation plate at intervals on the circumference around the fulcrum hole, each setting hole has a different height position relative to the fulcrum hole in order. Therefore, if you select a setting hole with a large difference in height from the fulcrum hole and assemble the positioning pin, the inclination angle of the workpiece mounting surface of the pedestal, that is, the indexing angle of the workpiece will increase. .

The relationship between the fulcrum hole and the setting hole on the installation plate is that a plurality of setting holes are arranged at equal intervals on the circumference around the fulcrum hole, but the simplest relationship between the fulcrum hole and the setting hole is The arrangement is such that a plurality of setting holes are arranged at equal intervals on a single circumference centered on the fulcrum hole, but in this case, the mechanical strength of the installation plate is Due to the problem, the distance between adjacent setting holes must be greater than a certain value, so the radius of the circumference where the setting holes are located must be set to a large value, which increases the size of the installation plate. Suitable for machining large workpieces.

In addition, if multiple circumferences with different radii are set for one fulcrum hole, and multiple setting holes are provided at equal intervals on each circumference, the spacing between adjacent setting holes should be set to be sufficient for mechanical strength. Since each setting hole can be placed within a relatively small radius around the fulcrum hole, the dimensions of the installation plate can be made relatively small, which reduces the overall size of the indexing device. Can be made smaller.

Furthermore, a plurality of fulcrum holes are provided adjacently in a fixed arrangement relationship,
When multiple setting holes are arranged on a single circumference around each fulcrum hole, the fulcrum hole group can be The dispersion range of the set hole group and the set hole group can be made sufficiently small, and as a result, an extremely compact indexing device can be obtained.

As mentioned above, there is a limit to reducing the distance between adjacent setting holes to a small value due to the mechanical strength of the installation plate, and therefore the indexing angle interval between each setting hole becomes relatively large.
Although it is not possible to obtain a fine indexing angle, it is possible to prepare multiple positioning pins with different support diameters and select this positioning pin to determine the angle between the indexing angles of adjacent setting holes. Become.

It is assembled to the upper vice piece 7a. FIG. 2 is an overall perspective view showing how the indexing device 1 is assembled to one vice piece 7a.

Figures 3 to 5 show an embodiment of the installation plate 2, which is the main component of the indexing device l, and mounting holes 2c are provided at the center of both ends of the horizontally long rectangular flat plate. At the same time, it is constructed by opening a fulcrum hole 2a and a setting hole 2b, and is attached to one vice piece 7a with a screw using the hole 2c.

In the case of the embodiment shown in FIG. 3, one fulcrum hole 2a is provided at the upper part of one end of the flat plate, which is the main body, slightly toward the center, and one fulcrum hole 2a is opened at the upper part of the flat plate, which is the main body, near the center of the other end. Fulcrum hole 2a
It is constructed by opening seven setting holes 2b at equal intervals on the circumference of a constant radius r1 centered at . Each setting hole 2b is provided at an indexing angle of 5°, but since they are arranged at regular intervals on a single circumference, a large vertical width is required to provide the setting hole 2b, and therefore the indexing angle is 0°
It is in the range of ~30°. In the case of the embodiment shown in FIG. 3, since the value of the radius rl is large, the pedestal 3 attached to the installation plate 2 is naturally long, which makes it suitable for handling a relatively large workpiece W. It has become.

In the case of the embodiment shown in FIG. 4, one fulcrum hole 2a is provided at the upper part of one end of the flat plate, slightly toward the center, and the other side of the flat plate has a radius of "2" around the fulcrum hole 2a. Five setting holes 2h are arranged at equal intervals on the circumference of
It is configured by opening two setting holes 2b. Both groups of setting holes 2b are provided at intervals of 10° at an indexing angle, and the setting holes 2b of one group and the setting holes 2 of the other group are adjacent to each other.
b, the indexing angle is shifted by 5°, and the indexing angle range is from 0° to 45°. In the case of the embodiment shown in FIG. 4, since the radii r2, j'J6 and r3 can be made sufficiently smaller than the radius r1, a large number of setting holes 2b can be provided within a narrow height range. Compared to the embodiment shown in FIG. 3, a large indexing angle range can be obtained even with a flat plate of approximately the same size, but since the radii r2 and r3 are small, the length of the pedestal 3 is also small, and therefore a small work W suitable for handling.

In the case of the embodiment shown in FIG. 5, four fulcrum holes 2a are arranged adjacent to each other in a substantially rhombic shape at the upper part of one end of the flat plate slightly toward the center, and each fulcrum hole 2a is provided at the other side of the flat plate. It is constructed by opening several setting holes 2b on the circumference of the same radius r4 centered on the hole 2a. Each setting hole 2b is set so that the lower the fulcrum hole 2a is provided, the smaller the indexing angle is, and the higher the fulcrum hole 2a is provided, the larger the indexing angle is. ing. In this way, in the case of the embodiment shown in FIG. 5, the position of the fulcrum hole 2a is changed up or down depending on the magnitude of the indexing angle, so the handling operation is a little more troublesome than in the embodiments already shown. However, even though the distribution range of the fulcrum hole 2a and the setting hole 2b is narrow, a large indexing angle range can be obtained.

FIG. 6 is a side view showing the configuration of the positioning pin 5. The positioning pin 5 has a fitting part 5a that fits into the setting hole 2b, and a diameter larger than the fitting part 5a to mount and support the holder 3. It is composed of a cylindrical support portion 5b. This positioning pin 5 is available in five types with different diameters of the support portion 5b. For example, the radius "1" shown in FIG. 3 is 80 m.
When applied to embodiment m, the diameter of the support portion 5b is 6.
000mm reference pin and the diameter of the support part 5b is 8.79mm
The diameter of the first pin of 2 mm and the support part 5b is 11.584 mm.
mm second pin and the diameter of the support part 5b is 14.374 m
The diameter of the third pin m and the support portion 5b is 17.16
Five pins including a fourth pin of 1 mm are prepared, and by assembling the reference pin into the setting hole 2b with an indexing angle of 10', the workpiece mounting surface 3b of the pedestal 3 can be tilted at an angle of 1.
By indexing at 0° and assembling the first pin into the same setting hole 2b, an indexing angle of 9° can be obtained; the second pin is 8°, the third pin is 7°, and the fourth pin is 6°.
An index angle of ° can be obtained. That is, the indexing angles set at 5° intervals by the setting holes Ill can be indexed at 1° intervals by selectively using the positioning pins 5 of different diameters of the support portion 5b.

Note that the diameter of the support portion 5b of the positioning pin 5 for changing the indexing angle by 1° is determined according to the value of the radius r on the installation plate 2.

7 and 8 show an example of the structure of the cradle 3, in which a shaft hole 3d is formed in the lower surface of one end of a flat main body 3a with a flat upper surface 3b. The portion 3c is formed in a bulging shape, and a locking piece 3e is protrudingly provided on the upper surface of the other end of the main body portion 3a to prevent the workpiece W mounted on the workpiece mounting surface 3b from slipping down. ing. This pedestal 3 has a fulcrum pin 4 fitted and assembled into the fulcrum hole 2a.
By fitting into the shaft hole 3d, it is swingably assembled to the installation plate 2, and the lower surface of the other end is fitted into the setting hole 2b of the installation plate 2.
By placing it on the positioning pin 5 assembled in
The workpiece mounting surface 3b is determined at a desired angle.

9 to 11 show examples of angle indexing of this cradle 3. By assembling the reference pin of the positioning pin 5 into the setting hole 2b indexed at 0°, the workpiece mounting surface 3b is set at 0°. By assembling the positioning pin 50 reference pin into the setting hole 2b indexed at 10°, the workpiece mounting surface 3b is indexed at 10°, and the positioning pin 5 is inserted into the setting hole 2b also indexed at 10°. By assembling the third pin, the workpiece mounting surface 3b is indexed at 7°.

In this manner, in the illustrated embodiment, the angle of the workpiece mounting surface 3b can be determined at 1° intervals by the combination of the setting hole 2b and the positioning pin 5.
