Description

In the process of manufacturing metal structures of frames, bridges, cranes, ships, boilers, etc., operations associated with marking and marking of the centers of holes for riveting on a varietal, sheet, figured and similar material have a significant proportion. Markers, using drawings, make up, according to which templates are made, and already from these templates, marking lines and points are transferred to the material. All this work requires a whole range of instruments (triangles, dirks, center pins, rulers, hammers, control center pins, etc.), the use of which often alternates, and this. causes a large expenditure of time on work and negatively reflects on the accuracy of its implementation.

It has already been proposed to replace the templates and a large number of tools when marking with a single device, making it possible to directly mark the material according to the drawing. This device consists of a body in the form of a ruler with a block at the end which rests on the bead of material moving along it and

carrying mobile center punch on it. Thus, with the presence of rectilinear scales located one on the side of the material, and the second along the panel, it was possible to mark the centers of the material openings in two mutually perpendicular directions.

However, these known devices are not widely used, since they do not have sufficient versatility. For example, in order to mark the centers of holes located in the shih-shtam order, these devices require careful installation when marking each row of centers.

The present invention is a further development of these instruments and is intended to make them more versatile. This goal is achieved by the fact that perpendicular to the body of the ruler of the device there is a movable carriage along it, carrying a slider with a center punch moving along it. Thereby, the limits of use of the device, as will be seen, the examples of its use described below will be significantly extended, in particular, for example, the basting of the centers of the holes arranged in a checkerboard pattern is simplified.

On what (tezhe Fig. 1 depicts the proposed device in a top view; Fig. 2 - section along AA; Fig. 3 - section according to BB; Fig. 1; Fig. 4,5 and 6 are examples of the use of the device.

The body of the device is made in the form of a ruler / with a guide slot for sliders 2. Each slide consists of a sleeve 3 with an abutment ring 4 mounted on it outside and a spring 5 placed inside to act on the hub 6 of the center punch 7. The nut S is screwed onto the sleeve 3, which draws it towards the ruler /. Upon success, the head of the center punch 7 is lowered and captures the sleeve core 6. Thus, the center and lateral risk of the circumference of the hole are applied simultaneously. Spring 5 serves to return the pivots to their original position.

At one end of the ruler 1, when marking the varietal material, a stop plate (not shown in the drawing) is placed, which serves to guide the device along the material board. When marking the same sheet material on the bracket, P is installed perpendicularly to the ruler 1, the tape measure 10, the tape of which is guided by the rollers 11. The device is set to the required pitch along this tape.

A distinctive feature of this device is the use of perpendicular to the ruler / carriage 12, also made in the form of a ruler with a slot

for the slide 13, arranged in the same way as the sliders 2. The carriage 12 can move along the ruler /; being removable it can be installed on both sides of the ruler /. Both the ruler / and the carriage 12 are provided with divisions for installing sliders.

With a two-hole, three-hole, and so on arrangement of the holes, the slides are located on only one ruler 1 (Fig. 4) at the corresponding distances from each other. In this case, the carriage 12 is removed.

In the case of the need to mark the holes in the checkerboard - on. The carriage is set to a row. At the same time, if at the beginning of the marking part there is a center of one hole (middle row of), then the carriage 12 is installed on one side (on the left side of the drawing) of the ruler / (Fig. 5), and if the centers of two holes (Fig. 6), then on the other side (on the right side of the drawing) of the ruler /.

To check the uniform pitch, a reference pedometer 14 with a center punch 15 set at a distance equal to the required pitch from the center punch of the slide 2 is installed on the ruler.

The subject matter of the invention.

A device for basting the centers of holes on a varietal, sheet, figured, and similar material using a body mounted on the calf as a ruler, carrying slides with cores, characterized by the use of a carriage 12, perpendicular to the ruler body, movable along it and carrying the slider 13 with center punch. to the author's testimony of V.I.
