Description

DETAILED DESCRIPTION OF THE INVENTION (A) Object of the Invention (a) Industrial Application Field The present invention relates to a centering device and center punch, and in particular, to an accurate and quick centering operation, as well as a punch mark operation. This invention relates to a centering device and center punch that can save labor.

b. Conventional technology Conventionally, in the production of various molds used for silver and gold processing, molds for molding synthetic resins, molds for casting, and general parts of machines and equipment, appropriate methods have been used. Place the metal piece to be machined on a surface plate, cover any surface of the metal piece with a paint of an appropriate color in advance, and after drying, use an instrument such as a hide gauge or digital hide gauge. It is known to make a punch mark by making a mark using a small hammer, and then hitting the tip of a punch with the point of intersection of the marks with a small hammer.

However, the above-mentioned known technology not only requires processing steps such as coating the surface of the metal workpiece with paint and scribing after it dries, but also precisely placing the tip of the punch at the intersection of the marks. Positioning requires considerable skill, and the quality of the product is determined by the accuracy of the positioning.
Since marks are formed on the surface of the metal workpiece, the work efficiency is significantly impaired due to the necessity of removing the marks and the coating material covered with the marks.

Therefore, place the point of the punch directly on the surface of the metal piece (1) and touch it directly with the intersection of the 7
Instead of striking, a magnetic metal body with a rod-shaped lens in the center and an insertion hole in which punches can be attached and detached alternately is used.
A magnetic gold mold is placed on the markings made on the metal workpiece, and is placed through a rod-shaped lens installed in the insertion hole to a position where the intersection of the markings and the intersection marked on the tip of the lens overlap. After confirming that both intersection points match, gently pull out the rod-shaped lens without displacing the magnetic metal body, insert a punch into the insertion hole instead, and use a small hammer to hit the head of the punch. The product name ``Magnetic Punch'' was proposed and is widely used.

However, in the case of the "magnetic punch" proposed by this proposal, the accuracy of abutting the tip of the punch on the intersection of the markings is high, but since it is passed through a rod-shaped lens, it is time-consuming and has the disadvantage of lacking in work efficiency.

In addition, there is a proposal for a punch mark tool (Patent Publication No. 56-51075) that can make a mark at a desired angular position on the same circumference of the end face of a pipe flange. In this proposal, the marking work can be omitted, but the punch mark can only be placed on the circumference of the end surface of the pipe flange at the opposite angle to the desired angle. It does not have the function of freely centering and attaching punch marks at arbitrary distance intervals on the surface of processed hardware,
Furthermore, no suggestions have been disclosed.

Problems to be Solved by the C2 Invention In view of the above, the inventor completed the present invention as a result of research. Therefore, the first object of the present invention is to provide a centering function that does not require marking in advance, and to immediately imprint a punch mark by tracking the centering. A further object of the present invention is to provide a centering device and center punch that can perform centering accurately and quickly, save labor in stamping punch marks, and allow production even by less skilled workers. A centering device [4-fold center punch] that can improve the properties.

The above two objects and other objects and features of the present invention can be understood in detail from the following description.

And, if necessary, operate the fast-forwarding element to fast-forward the idler for more accurate centering, and also to perform scribing work, which can also be configured to save labor. can.

(However, the lower part of the figure is omitted.) (C) Effects Since the present invention is based on the configuration described in Item 112, it has the following effects.

1. Notches are provided on both side edges of the surface plate, and the X-axis guide is manufactured and connected to the notches as a block, so the manufacturing work of the surface plate is easy and economical.

2. Since the X-axis guide and the X-axis guide are precisely arranged and connected in the right angle direction, the total distance of 4111 between the X and X-axes can be accurately and easily operated.

3. Centering is easy and accurate, there is no need to scribe, and punch marks can be carved quickly without requiring any skill.
Work is labor-saving and productivity can therefore be improved.

4. Since the embossing head moves up and down, the frequency of replacing the punch depending on the height of the workpiece is extremely low.

5. The displacement of the engraving head in the X-axis and Y-axis directions is light and smooth, and by operating the rapid feed element, it is possible to center and engrave punch marks, and it is also suitable for scribing work.

6. Since the structure is simple, it can be provided at low cost.

This invention has various industrial effects.
