RU44579U1 - LOCATOR'S TEMPLATE WITH EXTENDABLE LINE FOR MARKING ANGLES AND HOLES IN PARTS OF PARTS - Google Patents

Abstract

A device called a locksmith template with a retractable ruler for marking corners and holes in the shelves of parts, belong to the section of various technological processes, and in particular benchmark measuring tool.

The prototype is a metalwork tool in the form of a square, which is designed to control right angles, and marking parts with drawing transverse lines on the parts.

These transverse lines, in this case, are serifs or axial lines of the planned holes, and in order to mark holes on the shelves of parts, a caliper is now used, and if the holes are at the same distance from the edge of the shelf, then the required hole size is set on the tool, but if all holes are at different distances each time you need to set a new size.

The proposed template, when marking holes located at any distance from the edge of the shelf, marks all holes in automatic mode, without setting up the tool.

Such marking is possible due to the use of an inclined bar with two working edges and a reverse scale, you only need to combine the divisions on the scale with the transverse line, the division should be equal to twice the distance to the shelf.

In addition, the benchmark template has a retractable ruler in which both attachment points, when installed at different angles for drawing, move: one along the grooves of the corner strip, and the other rearranged through the holes, and the angle of inclination can be changed every 5 ° to 60 °. The template is simple in design and when marking provides increased accuracy.

Description

The present invention relates to the technological section, in particular, a measuring tool for marking locksmithing, meaning marking oblique angles for cutting and marking holes on parts.

Of the known tools for this purpose, one can name: a surface gage, a goniometer, a vernier caliper and a locksmith's square, which serves to control the marking and drawing of transverse lines.

However, none of them is intended for drawing, as a ruler, lines for cutting at a certain angle, as well as marking several holes at different distances from the edge of the shelf, without rebuilding and setting the size on it, in automatic mode.

The design of the bench model proposed in this application, made in the form of a square with a retractable ruler and with an inclined bar, installed, relative to the main support bar, at a constant angle “a” with working edges for drawing, allows you to perform all the marking, drawing and control , one such tool.

An analogue of such a tool for drawing oblique sections, when using a retractable ruler and marking holes in the shelves of parts, without setting the size on the measuring tool, for sizing the centers of the holes, is not known to the applicant.

The use of a measuring device, called a bench model, will improve the accuracy of manufacturing parts and simplify the marking process.

Figure 1 shows the device template bench, made in the form of a square with an inclined bar and a retractable ruler, rotated at an angle of 60 degrees, and fixed with a pin.

Figure 2 shows a stepped section 1-1, along an angular bar with a step, a groove and a pin of a retractable ruler, through blind holes in a support bar and a pin to fix a retractable ruler. The hole for securing the slide bar in its original position, under the corner bar, does not fall into the cut.

The device template bench with a retractable ruler.

The support bar pos. 1 of figure 1, with a reverse measuring scale 2, with a pin 3 and deaf holes 4 for fixing the slide bar 5, with a measuring scale, and with a pin 6 of figure 2, section 1-1.

With this pin, a retractable ruler, with the possibility of rotation and movement, is fixed at the bottom 7 of figure 1, with a screw 8 and a washer 9, abutting against the shoulder on pin 6 of figure 2, and two holes 10 at the other end of the line 5 of figure 1, pin 3, provide the installation angle of the retractable line 5, with an interval of 5 gig, up to 60 gig.

The groove 7 is located in the upper part of the corner strip pos.11 of figure 2, which is connected from above, at right angles, with the support bar pos.1 of figure 1, and has a longitudinal step pos.12 with a through hole 13 for fastening the ruler 5 to starting position, pin.

In this position, the slide bar 5 is used to make marks and transverse lines 14 of FIG. 1, the axes of the holes in the parts.

Both strips pos. 1 and 11 are connected rigidly, in the same plane, to an angular plank, an inclined plank 15 with an intermediate plank 16 having a stepped cutout 17, equal in height to a ruler 5.

An inclined bar 15 having two working edges and connected to the support bar 1 at a verified angle “a” equal to 26.5 gig. Which provides the necessary ratio of the side-legs of the formed right-angled triangle, as "one to two", and the outer working edge of the inclined plate 15, coincides with zero pressure on the reverse scale 2, applied across the entire support plate.

To facilitate the calculation, when marking holes, the distance from point “A” with zero scale division to point “B”, where the inner edge of the inclined bar 15 intersects the scale 2 must be equal to 20 mm, as in FIG. 1, or a multiple 20 mm, in the case of a possible increase in the benchmark template twice, or more.

The pin 3 in figure 1 is removable and rearranged when the retractable ruler 5 is changed, made according to the diameter of the holes 4, 10 and 13, with a chamfer and a hat at the ends.

When increasing the size of the template, chamfers are made on the inclined bar 15 and the angular bar 11, and are not shown in FIG. 1, and the initial position of the slide bar 5 in FIG. 1 is shown conditionally, it is pushed into the slot until it stops in the seal and locked in the original pin position.

Using the benchmark for drawing oblique lines at an angle of up to 60 degrees.

The retractable ruler 5 takes its initial position when, on one of the sides of the part, serifs are made using the measuring, reverse scale 2 of FIG.

Then take out the pin 3, and pulling the ruler 5, turn it to a predetermined angle and fix it in this position with the pin 3.

The benchmark template, with the ruler 5 installed at an angle, is pressed to the edge of the part shelf, and combining the notch on the part with the plane and the line of the working edge of the ruler, draw a line.

Work with a metalwork template when marking holes in parts.

First, mark the places of the axes, and with the help of a retractable ruler 5, immediately draw all the transverse lines pos.14 figure 1.

Then, all serifs are carried out corresponding to the axial longitudinal lines of the planned holes, without preparing the device and rearranging the dimensions on the bench metal, wherever, on which of the lines, and at whatever distance from the edge of the shelf they are located, while using the working edges of the inclined plank 15 and the reverse, measuring scale 2.

Example: On one of the transverse lines, you need to mark the centers for the four holes. The closest to the edge of the shelf will be at a distance of 25 mm, the other three holes go at a distance of 35, 50 and 60 mm, then, after a simple calculation, using the angle “a” of the inclined plate 15, which is a hallmark of the benchmark template proposed in the application, for each hole is marked by a corresponding division on a scale of 2 - for a hole located 25 mm from the edge, a division of 50 mm will correspond, for a size of 35 mm, a division of 70 mm, then 100 and 120 mm.

The metalwork template is pressed to the edge of the part shelf and, alternately, in automatic mode, combine the intended divisions on the reverse scale 2 with the same transverse line, put serifs on it using the external working edge of the inclined plate 15.

Use the internal working edge for marking when you need to mark holes located from the edge closer than 20 mm.

The benchmark template is simple in design, simplifies the marking process and can be used in production, the installation of an intermediate strip 16 with a cutout 17 of FIG. 1 is a hallmark of the claimed device since with enlarged dimensions of the template, it ensures that the retractable ruler 5 is pressed against the marked part, this expands the possibilities of its use.
