Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plane of a work member having a right-angled corner which can be used as a reference for determining a punching position (marked by a punching tool).
Punching jigs and punching jigs that are used for positioning drilling holes such as pilot holes, bolt holes, mounting holes, etc., and can be stamped with a punch tool without performing scribing work It is about attachments.

[0002]

2. Description of the Related Art Generally, when various holes are drilled at predetermined positions on a plane of a work member, or in the case of a mass-produced product, a jig for punching without performing a scribing operation, such as ( a) a simple punching jig having a cross guide rail frame; (b) means for directly punching without performing scribing or punching work, for example, when the work is vertically and horizontally with respect to the center of the spindle. A horizontal boring machine that can move or the center of the spindle moves with respect to the workpiece.
A means for fixing a work member to a table of a device such as a milling machine, a jig borer or the like, and directly drilling at a determined position determined by movement control;
Means for performing direct drilling by using an automatic C positioning device and the like have become common.

[0003] However, the case (a) is preferable for a means for boring a large number of products and parts with a small number of lots. Is troublesome and the work efficiency is low. In the case of (b), a horizontal boring machine, a milling machine,
Equipment such as jig borers must be provided, and in the case of (c), it is expensive. Therefore, in any case, it is used as a means for drilling many kinds and small quantities of products and parts with a small number of lots. Therefore, drilling of a large variety of small quantities of products, parts, etc. is performed, regardless of the size of the workpiece, in the plane of the workpiece member having a right-angled corner that can be used as a reference, a pilot hole, a bolt hole, In order to drill holes such as mounting holes, a work member is placed on a scribing table such as a surface plate, and a height gauge, various types of calipers, a scale for measuring length, a right angle ruler, a right angle A scribe line is drawn by appropriately selecting and using various scribe tools such as a block and a scribe needle, and an intersection of the two-axis (X-axis, Y-axis) direction of the scribe line is obtained.
At present, the punching process is performed by an old-fashioned means of performing punching after punching at the intersection.

[0004]

However, in the conventional drilling, the convenience and the economical work area can be achieved by using existing tools which are prepared in many machining plants or using tools which are inexpensive even if they are prepared. Although there is an advantage in, after punching to the intersection of the scribing line by finding the intersection of the scribing line by scribing work, it must be perforated,
Performing such work on each of the work members, even though the number of lots is small, is not only unfavorable in terms of work efficiency due to the large number of work steps, but also not capable of expecting uniform and high-precision processing, but also scribe. The scribing line engraved on the surface of the work member by the operation remains, and the quality of the product or part is degraded.

The present invention is most suitable when the number of lots is small and the user wants to use the work without being restricted by the size of the work, and is efficient without performing the scribing work, and furthermore sets the punching position. The advantage of high precision and accuracy, which improves the overall work efficiency of drilling, and makes it possible to effectively use punching jigs that do not leave scribe lines on the surface of products or parts, and that existing tools can be used effectively. It is an object to provide an inexpensive punching jig and an attachment for the punching jig which adhere to the above.
