Abstract

This invention relates to welding primarily in shipbuilding and can be used in mechanized production lines. The purpose of the invention is to automate the direction of movement of the welding head during cross set welding. The device comprises a copy roller 1 connected by means of a horizontal rod 2 with a spring-loaded electric switch 3 without a middle position. The housing of the electrical switch 3 is connected by means of a vertical rod 5 to another electric spring-loaded switch 6, which is rigidly connected to the housing 9, on which the welding head and the stem of the switch 10 of the welding arc are fixed. The device is connected by a flexible connection with an electric motor driving a longitudinal movement of the welding tractor or gantry, as well as with an electric motor driving a vertical movement of the welding head. 2 Il.

Description

The invention relates to welding mainly in shipbuilding, and more specifically to devices designed to automate the direction of movement of the welding head, and can be used in mechanized production lines (MPL) for the manufacture of flat sections at the welding position of the cross set with an asymmetrical profile of the main beam.

The purpose of the invention is to automate the movement of the welding head.

Figure 1 shows the device, a general view; figure 2 - view And figure 1.

The device is mounted on a welded installation and contains a cam roller 1, a horizontal rod 2, an electric switch 3 without a middle position, spring-loaded 4, a vertical rod 5, an electric switch 6 without a middle position, spring-loaded 7, a movable element 8, telescopically connected to the housing 9, the welding arc switch 0, the housing 11 of which is rigidly connected to the welding device, for example a portal, the second copy roller 12. The device moves along the ship hull structure s of the webs 13, 14 of cross beam set, beam 15 set with the main direction of unsymmetrical profile. The welding head 16 is rigidly connected to the housing 9.

The device works as follows.

When contacts H 3 of switch 3 are closed and BUT contact of switch B is switched, the device, together with the welding head 16, is lowered down onto the panel 13 of the ship hull structure. When the welding head 16, which is directed at an angle between the panel 13 and the beam 14 of the cross set, closes the NO contact of the switch b and the contact of the switch 10. At the same time

the motor of the horizontal movement of the welding gantry is turned on and the welding arc is ignited. When the welding head moves with the device up to the main direction set beam 15, the copy roller 1 abuts against it and closes the contact of the NO switch 3. The arc stops and the horizontal movement of the welding gantry stops. At the same time, the motor for driving the vertical movement of the welding head upward turns on. In this case, under the action of the spring, contact H 3 of the switch 6 is closed. As soon as the cam roller 1 is released and under the action of the spring 4 it closes contact H 3 of the switch 3, the vertical drive motor of the welding head 16 is turned down. 15, when the device is lowered, the NO contact of the switch 6 is closed, turning on the portal longitudinal electric motor. However, due to the open contact of the switch 10, the welding arc will not turn on. When the copier roller 12 is released, the rod 5 under the action of the spring 7 closes the contact of the NC switch 6, turns off the portal horizontal movement motor, moves the welding arc and turns on the vertical movement motor driving the welding head down. contact BUT of switch 6 and switch 10 contact, turning off the motor driving the vertical movement of the welding head down and turning on the drive motor of the horizontal movement of the welding portal with simultaneous ignition of the welding arc. When the device touches the next beam of the main direction set, the whole cycle repeats.

The device can work simultaneously with several welding heads welded cross-set beams, which will significantly increase labor productivity.

The use of the invention will allow the welding of the cross set in automatic mode.
