Description

DESCRIPTION

IMPROVED TOOLS FOR WELDING PARTS

TECHNICAL SECTOR

The present invention refers to an improved tooling to enable accurate and reliable welding between parts, so that the welding robot can identify in which position the tooling is located, avoiding welding deviations.

BACKGROUND OF THE INVENTION

In the current state of the art, tools of various kinds are widely known and used in the welding process, where the tool is placed manually and fixed with centering devices.

The welding robot performs the operation according to the programming of some coordinates, so if the tooling is not correctly positioned, the welding is not carried out in the correct location and the penetration is inadequate, causing an incorrect welding.

In this sense, the correct and very precise positioning of the tooling on the welding table is essential and has a direct impact on the quality of the welding obtained when the pieces are joined.

Thus, from the known welding tool derives the difficulty of correctly positioning and fixing it on the welding table to obtain a precise and quality welding.

All this leads the applicant of the present utility model to detect the need to implement improvements in the tooling for welding parts.

DESCRIPTION OF THE INVENTION

The tooling that is recommended solves in a fully satisfactory way the problems previously exposed and improves the precision in the part welding operation.

Thus, the tooling of the invention is provided with centering devices and at least three reference pins strategically located on the surface of the tooling to facilitate the specific identification of the position of the tooling on the welding table.

Advantageously, the inclusion of the reference pins in the tooling avoids position deviations of the welding, precisely locating the location of the tool with respect to the welding table.

In this way, each reference pin is made up of a cylindrical body from which a conical tip termination emerges. Preferably, the conical tip termination of each reference pin has an angle between 20 ° and 40 °, preferably 26 °, thus allowing a precise and agile identification of its position by the welding robot.

On the other hand, it should be noted that the reference pins are necessarily made up of a rigid material to enable their identification by the robot, preferably the material of the reference pins being aluminum, a material that is widely used in the sector to lighten the tools. that are manipulated manually and frequently.

Finally, it should be noted that, optionally, the reference pins are removable, thus facilitating their convenient storage when they are not being used.

BRIEF DESCRIPTION OF THE DRAWINGS

To complete the description that is going to be made below and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part of said description, where, with an illustrative and non-limiting nature, it has been represented the next:

Figure 1.- Shows a perspective view of the improved tooling for welding parts according to a preferred embodiment of the invention which is mounted on a welding bench.

Figure 2.- Shows a perspective view of the improved tooling for welding parts according to a preferred embodiment of the invention.

Figure 3.- Shows a detailed view of a reference pin contained in the improved tooling of the invention and represented in Figures 1 and 2.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the outlined figures, specifically figures 1, 2 and 3, it can be seen how in a preferred embodiment of the invention the improved tooling for welding parts preferably has three reference pins (2) which are of a rigid material to allow the detection of its position by the welding robot.

As can be seen in figure 3, each reference pin (2) has a cylindrical body (4) from which a conical tip termination (3) emerges, which facilitates the centering and positioning of the element to be welded.

As seen in Figure 2, the reference pins (2) are distributed around the perimeter of the improved tooling (1) to precisely position it with respect to a welding table (5).

Advantageously, the detailed configuration allows the easy identification of the reference pins, so that the welding robot can be informed of the specific position of the improved tooling with respect to the welding bench (5) and allow any type of welding (bead, laser , etc.) with great precision.

Although it is true that the known tools include centering devices (6) that participate in locating said tooling on the welding bench (5), the inclusion of at least three reference pins (2) in the improved tooling (1) , offers an advantageous situation for the welding robot to make the union between the pieces in a precise way.
