Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a scale holder, and particularly to a scale holder used when marking a flat plate.

[Prior art]

Conventionally, when marking a large flat plate, the scale was placed on the flat plate, the scale was visually aligned with the edge of the flat plate, and then the scale was held down by hand with a scribing needle and the scribing work was done. was going there.

In this way, after visually aligning the scale and the edge of the flat plate, the scale is pressed down by hand and scribed, so the scale moves and bends or shifts during scribing, making it difficult to accurately mark the dimensions. It had many drawbacks, such as being difficult to maintain.

[Purpose of invention]

An object of the present invention is to provide a scale holder for accurately marking.

In other words, the purpose of the present invention is to eliminate the above-mentioned drawbacks by creating a scale that accurately fixes the scale, accurately aligns the scale graduations and the jig, and enables reliable marking work. The purpose is to provide a holder.

[Structure of the idea]

The scale holder of this invention has two first
a first body having a first square hole in which a guide shaft and a first fine adjustment screw are fixed, a scale can freely slide on the same surface, and a first knob passing through the first square hole; a first square hole having a second square hole at a position opposite to the first square hole and slidable on the first guide shaft;
a second hole that guides the first fine adjustment screw, a second fine adjustment knob that has a female thread that engages with the first fine adjustment screw, and a second hole that penetrates the second square hole. and a second body provided with two knobs.

[Explanation of Examples]

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention.

The main body 1 has two guide shafts 3, a square hole 4 in which the fine adjustment screw 2 is fixed and a scale 12 can freely slide, and a square hole 4.
It is provided with a knob 9 that penetrates through the. The main body 8 also has a scale 1 at a position facing the square hole 4 of the main body 1.
A square hole 5 is provided so that the screw 2 can freely slide, and the guide shaft 3 of the main body 1, the slidable hole 6, the hole 11 for guiding the fine adjustment screw 2, and the fine adjustment screw 2 engage with each other. It includes a fine adjustment knob 7 having a female thread, and a knob 10 penetrating through the square hole 5.

Next, the operation of the embodiment shown in FIG. 1 will be explained.

Fit the guide shaft 3 of the main body 1 and the fine adjustment screw 2 into the holes 6 and 11 of the main body 8, respectively, and screw the fine adjustment knob 7 into the threaded part of the fine adjustment screw 2 to connect the main body 1 and the main body 8. Combine. At this time,
Knob 9 and Knob 10 are square holes 4 and 5, respectively.
Make sure that it does not come out inside.

Next, the scale 12 is inserted into the square holes 4 and 5, the dimension to be marked is projected from the outer end surface of the main body 8, and the knob 9 of the main body 1 is screwed to fix the scale 12 to the main body 1. In this state, the fine adjustment knob 7 is rotated to move the outer end surface of the main body 8 to the dimension to be marked, and the knob 10 is screwed in to fix the main body 8 to the scale 12.

After positioning in this manner, a scribing needle is applied to the outer end surface of the main body 8 to perform a scribing operation.

[Effect of idea]

With the scale holder of the present invention, when marking was done only with a scale, it was not only impossible to accurately match the dimensions, but also it was unstable because the scale was held down by hand during the marking work. On the other hand,
The use of a scale holder has great effects, such as accurate dimensioning, stable marking work, and shortened working time.
