Abstract

PURPOSE:To enhance the marking efficiency to a circular arc surface, in a marking device for a product whose surface to be marked has a circular arc shape such as an insulator cap metal fitting, by supporting the product around the center point of a circular arc in a freely rotatable manner and pressing the holding stand of a marking member to the surface to be marked to move the same in the tangential direction of the circular arc. CONSTITUTION:When the lower part of the side surface of an insulator metal fitting W(hereinbelow referred to as a work) is marked with a lot No, a predetermined marking member (a) is set to a holding stand 13 and the work W is set to a support mechanism 1. The surface to be printed of the work W is matched with the marking member (a) by a hydraulic cylinder 5 and the slide stand 14 is advanced by a hydraulic cylinder 15 to move the holding stand 13 toward the work W to bring the marking member (a) into contact with the surface to be marked. Then, the whole of the marking member (a) is moved in the direction shown by an arrow (c) by driving a hydraulic cylinder 20 to apply marking to the work W. Next, the slide stand 14 is allowed to recede in the direction shown by an arrow (b) to detach the work W.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marking device, and more particularly,
TECHNICAL FIELD The present invention relates to a product such as an insulator metal fitting which is capable of efficiently engraving on a product whose engraved surface has an arc shape.

[0002]

2. Description of the Related Art Conventionally, lot numbers have been assigned to metal products (hereinafter referred to as "workpieces"). To engrave characters and symbols such as, etc., an engraving member such as characters and symbols is stamped.

[0003]

However, the above-mentioned conventional stamping device by punching is not preferable because it gives a shock to the work, and when the stamped surface has an arc shape,
It had the drawback of being difficult to engrave and poor in workability.

Therefore, the present invention has been made in order to solve the above-mentioned drawbacks, and an object thereof is to efficiently mark an arc-shaped marking surface without giving a shock to a work. The object is to provide a marking device that can be used.

[0005]

In order to achieve the above object, the present invention provides a support for rotatably supporting a workpiece having an arcuate surface to be engraved around the arcuate center point. A mechanism, a pressing mechanism that presses the holding table holding the marking member toward the marking surface of the work, and a moving mechanism that moves the holding table in the arc-shaped tangential direction of the marking surface of the work, It is characterized by having.

[0006]

In the above structure, when the marking member is pressed by the pressing mechanism on the arcuate marking surface of the work rotatably supported by the support mechanism, the marking member is moved by the moving mechanism. , The workpiece rotates around an arc-shaped center point. At the time of this rotation, the marking surface is stamped.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view in which a part of one embodiment of the apparatus is a vertical cross section.

Reference numeral 1 denotes a support mechanism, which supports an insulator metal fitting (hereinafter referred to as insulator metal fitting) W. That is, the support mechanism 1 includes the cylinder 2 provided on the frame F.
A rod 3 movably provided therein, a rotatable head 4 provided at an upper end portion of the rod 3 and having a recess W ′ of the insulator fitting W as an outer shape, and a lower end side of the rod 3. And a hydraulic cylinder 5 for moving the rod in the vertical direction.

A pressing mechanism 10 is located on the right side of the support mechanism 1 and can move horizontally on a base 12 provided on a pedestal 11, that is, orthogonal to the axial direction of the rod 3. It is provided so that it can be moved in any direction. That is, the pressing mechanism 10 is slidable on the base 12 in the horizontal direction (see arrows a and b in FIG. 1) and has the holding base 13 for holding the marking member a at the end on the supporting mechanism 1 side. It is composed of a table 14 and a hydraulic cylinder 15 for moving the sliding table 14.

Reference numeral 20 denotes a moving mechanism composed of a hydraulic cylinder, which is configured to move the holding table 13 horizontally and in a direction orthogonal to the moving direction of the pressing mechanism 10. That is, the holding table 13 is, as shown in FIG.
A hydraulic cylinder (moving mechanism) 20 is movably provided on the slide base 14, and is fixed to the slide base 14 so that the holding base 13 can be moved in the arrow C direction.

Next, the operation of the apparatus of the above embodiment will be described. Now, at the bottom of the side surface of the insulator bracket W, a lot of "263"
No. Shall be stamped. Therefore, the marking member a having the numeral “263” is set on the holding table 13. Then, the concave portion W'of the insulator metal fitting W is inserted and placed on the head 4, and the hydraulic cylinder 5 is driven so that the print surface position of the insulator metal fitting W coincides with the horizontal position of the marking member a.

Then, the hydraulic cylinder 15 is driven to move the holding table 13 to the side of the scraping metal W (see arrow B), and the marking member a is brought into contact with the scraping metal W, and the pressing force is applied as it is. To do. And the hydraulic cylinder 20
Is driven to move the holding table 13 forward or backward (moving upward or downward in FIG. 2) so that the entire marking member a comes into contact with the insulator metal fitting W. After that, the slide base 14 is retracted (see arrow B in FIG. 1), and the insulator fitting W is moved to the head 4
Remove from. As a result, the insulator fitting W has a structure shown in FIG.
Rod No. as shown in. Is imprinted.

As described above, in the apparatus of the present embodiment, the marking member a is moved in the tangential direction of the peripheral side surface of the insulator metal fitting W while being pressed against the insulator metal fitting W, so that the marking material a is impacted. Can be easily engraved without giving.

In the above-mentioned embodiment, the example of the work W peeling metal fitting is shown, but it can be adopted if the marking surface has an arc shape.

[0015]

The apparatus of the present invention is provided with a support mechanism for rotatably supporting a workpiece having an arcuate surface to be engraved around the arcuate center point, and a holding table holding the engraving member. Since it is composed of a pressing mechanism that presses against the marking surface of the work and a moving mechanism that moves the holding table in the arc-shaped tangential direction of the marking surface of the work, it is easy without impacting the work. Can be engraved on.
