JPS60102501A - Device for omitting computation when position of size in scribing device is determined - Google Patents

Abstract

PURPOSE:To prevent scribing errors, by transferring the size on the next positioning piece from the size, which is set by a positioning piece and an auxiliary scale read by a cursor. CONSTITUTION:Magnets (not shown) are bonded to the back surface of positioning pieces 4, 4A..., which are discriminated by colors and the like, and the back surface of a cursor 6. A normal scale 2 and an auxiliary scale 3 are magnetized. When the sizes L1, L2, and L4 between points (a), (b), (c), and (d) are determined, the size L1 is set between a slant tip 6a of the cursor 6 and a mark 0 of the scale 3. A tip of the piece 4, i.e., the point (a), is aligned with the tip 6a. The next piece 4A is aligned with the mark 0 of the scale 3, i.e., the point (b). Likewise, L2 is set at the point (c) on the scale 3, and the size is transferred to the scale 2. The piece 4B is set at the point (c). The tip 6a is aligned with the corresponding point of the point (a) of the piece 4. The position of the mark 0 of the scale 3 is aligned with the scale 2, and the piece 4c is set.

Description

DETAILED DESCRIPTION OF THE INVENTION Cases a and b in which the marking device as shown in FIG. 1 has a permanent scale 2 in the groove on the top surface of the reference rail 1 and the drawing dimensions are displayed as shown in FIG.
L1 is between b and c, L2 is between a and d, and L3 is between a and d.
When determining the current dimensions, calculate the L1 dimension by counting the L1 dimension from point a on the scale, determine point b, then similarly calculate the L2 dimension and determine the Lc point. To determine point d again, L3-(
Point d cannot be determined unless it is calculated using the formula L1+L2)=L4.

This type of calculation occurs frequently when drawing dimension lines on the workpiece from the drawing, so it is necessary to calculate each time, but when calculating by reading various numbers, it is easy to make mistakes. Momentary confusion and illusions can lead to mistakes, resulting in defective products. It will be.

The present invention utilizes an auxiliary scale, a cursor, and a positioning piece in order to perform efficient work without making marking mistakes, and the positioning pieces are painted with numbers and colors to make their divisions clear, and the positioning of each set during work is made clear. The piece 4 shown in Figures 4 and 5 has a magnet 5 attached to the back side that can be magnetically attached to the permanent scale 2.The piece 4 shown in Figures 4 and 5 is designed to reduce mistakes and speed up work by allowing you to work while checking the dimensions. A protruding sagittal shape 4a for scale adjustment is provided at one end of the front side.The auxiliary scale 3 and cursor 6 shown in FIGS. 2 with the tip 6a on the permanent scale 2, positioning pieces 4 and 4.
A, 4B, 4C...When setting a large number of prepared pieces,
Set the dimension L1 between a and b between the slanted tip 6a of the cursor 6 and the scale 0 of the auxiliary scale 3, and align the cursor slanted tip 6a with the tip of the positioning piece 4, that is, point a, as shown in FIG. Next positioning piece 4A is placed at point b of scale 0 of 3.
Set the L2 dimension on the auxiliary scale in the same way for point C, transfer it to permanent scale 2, and set positioning piece 4B to point c. Next, for point d, do the same thing as taking the L1 dimension and L2 dimension. Align the inclined tip 6a of the cursor 6 with the point corresponding to point a of the positioning piece 4 of the permanent scale 2 in FIG.
By providing and setting the positioning piece 4C according to the size, the dimensions as shown in the drawing can be set without calculation.

Positioning pieces 4, 4A, 4B, 4C... on the permanent scale 2.
are set, the positioning pieces 4, 4A, 4B,
If you perform marking lines in sequence according to the scale of vernier 8 on 4C..., you can check the marking process, reduce mistakes, and measure speed.

Furthermore, it is clear that the present invention can be widely used in work for determining dimensions using a scale.
