These operations are sequentially repeated, whereby desired mark-pressing is performed on the top surface of the work W. Accordingly, the work can be mark-pressed automatically and efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a stamping device that stamps a workpiece by striking a stamping tool.

[Conventional technology and its problems]

An example of the prior art of the above-mentioned marking device is disclosed in Japanese Utility Model Publication No. 60-26929 proposed by the applicant of the present invention.

In the above-mentioned conventional device, the marking tool supported by the holder is pressed against the workpiece by the downward movement of the holder, and the pressing is performed by striking the holder with the downward movement of the piston incorporated inside the cylinder to prevent the workpiece from being pressed. This has the advantage that the stamping force drive device is smaller than a stamping device that stamps by pressing a stamping tool against the workpiece under pressure, and the entire device can be made smaller. Further, although the above-mentioned marking device is small in size, it has a large marking capacity, can stamp many characters with one blow, and is suitable for repeatedly stamping the same character string.

However, when the character string changes frequently, it is necessary to change or replace the engraving each time, which is very time-consuming, and being able to engrave a large number of characters at once is very powerful. Therefore, there is a risk of deforming the workpiece.

[Purpose of the invention]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned disadvantages and provide a small and compact marking device that can perform marking automatically.

[Structure of the invention]

In order to achieve the above object, the present invention provides a support plate that is movable in the left and right directions on the front surface of a support plate that is supported in a height-adjustable manner along a plurality of parallel guide posts that stand up from the upper surface of a work support table. A head support plate is attached, a drive device for the head support plate is supported by the support plate, and a circular tool head is provided on the underside of the head support plate, which is rotated by the rotation drive device supported by the head support plate. A number of marking tools that can move vertically and a spring that deflects the tools upward are provided on the outer periphery of the tool head, and on the head support plate, the tool head is rotated to correspond to the workpiece. The structure includes a hammer device for striking the upper part of the stamping tool.

[Effect]

When a workpiece is placed on the workpiece support table and a stamping tool selected by rotating the tool head is opposed to the lower part of the hammer device, the hammer device is activated and strikes the stamping tool. When a predetermined marking is made on the workpiece by the striking, the head support plate is moved by a required pinch to the right or left by the operation of the drive device. The marking device according to the present invention includes an operation of positioning the selected marking tool below the hammer device by rotating the tool head;
The hammer device sequentially performs the action of striking the marking tool and the action of moving the head support plate.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a pair of parallel guide posts 2 are erected at the rear of the upper surface of the workpiece support table 1, and a guide provided on the back side of the support plate 3 is provided on the outside of the guide posts 2. The cylinder 4 is slidably fitted, and the support plate 3 is tightened by tightening the bolt 5 threadedly engaged with the guide cylinder 4.
can be fixed at a height-adjusted position.

A long rail 6 in the left-right direction is attached to the front surface of the support plate 3, and an L-shaped head support plate 7 is attached along the rail 6.
is movable.

Further, a support plate moving motor 8 is attached to the back of the support plate 3, and a pinion 9 attached to the rotating shaft of the motor 8 engages with a rack 10 attached to the back of the head support plate 7. Therefore, as the motor 8 rotates, the head support plate 7 moves to the right or left.

A circular tool head 1 is provided on the lower surface of the head support plate 7.
1 is arranged, and a motor 12 for rotationally driving the tool head 11 is supported on the upper surface of the head support plate 7.

On the outer periphery of the tool head 11, stamping tools 13 are arranged in an annular manner at equal intervals, and each of the tools 13 is movable in the vertical direction, and is deflected upward by a spring 14 fitted on the outside thereof. .

Further, a striking hammer device 20 of a marking tool located below the head support plate 7 is supported on the front portion of the upper surface thereof.

Here, the hammer device 20 includes a cylinder 21, as shown in FIG. A spring 24 that contacts the cylinder 24 and a piston 25 that is pushed up by the spring 24 are incorporated, and the lower part of the striking rod 23 is inserted into an insertion hole 27 of a rod cover 26 attached to the lower part of the cylinder 21.

The piston 25 is lowered by air supplied into the cylinder 21 from an air supply boat 29 of a hend cover 28 provided at the upper part of the cylinder 21, and the spring 24 for pushing up the piston is contracted by the lowering. This spring 24 has a spring characteristic that becomes stronger than the elasticity of the spring 22 for pushing up the striking rod 23 when contracted by a predetermined amount. Therefore, due to the contraction of the spring 24,
The striking rod 23 is lowered, and the marking tool 13 is lowered by the striking rod 23. When the marking tool 13 is pressed against the workpiece W, the piston 25 strikes the striking rod 23. (See Figure 4).

FIG. 5 shows another embodiment of the hammer device 20.

Components similar to the hammer device 20 shown in FIG. 3 described above are designated by the same reference numerals, and the description thereof will be omitted.

In this hammer device 20, the lower end of a piston 25 and a push-up spring 24 are brought into contact with the upper surface of a rod cover 26, and a cylindrical elastic body 30 is fitted onto the lower end of the piston 25. Before and after striking the striking rod 23, the tip of the elastic body 30 elastically presses down the striking rod 23.

The marking device shown in the embodiment has the above-mentioned structure, and its operation will be explained next.

Now, when the work W is placed on the upper surface of the work support table 1, the motor 12 for driving the tool head rotates, and the tool head 11 is rotated. The marking tool 13 selected by the rotation of the tool head 11 is moved to the hammer device 2.
When it stops below 0, the hammer device 20 is activated and strikes the marking tool 13. By that beating, the work W
When the marking is applied to the drive motor 8 of the head support plate 7
is activated to move the head support plate 7 along the rail 6 by a predetermined pitch.

When the head support plate 7 stops, the tool head 11 is rotated by the operation of the motor 12, and when the selected marking tool 13 stops below the hammer device 20, the hammer device 20 is activated and the marking tool 13 is rotated. Hit 13.

Thereafter, the head support plate 7 is moved by a predetermined pinch along the rail 6, the tool head 11 is rotated to stop the selected marking tool 13 below the hammer device 20, and the hammer device 20 is moved for marking. The operation of striking the tool 13 is performed in order, and a predetermined mark is made on the upper surface of the workpiece W.

〔effect〕

17 = As described above, the present invention provides a drive device for moving a support plate that is movable in the left-right direction, a tool head that supports a marking tool on the support plate, a rotation drive device for the tool head, and Since a hammer device is provided to strike the marking tool of the tool head, it is possible to stamp the workpiece automatically and efficiently. It is possible to reduce the size of the entire device compared to stamping using pressure.

Furthermore, since the tool head supporting the marking tool is provided movably relative to the workpiece, a smaller drive device can be used compared to the case where the workpiece is moved.
