The invention relates to welding, in particular, to equipment for arc welding by melting electrode butt welds with oscillations of the electrode;

The aim of the invention is to reduce drive power.

The arc welding device with oscillations of the electrode (Fig. 1) consists of a base 1 on which the drive 2 of the carriage 3 movement mechanism is installed and the oscillation mechanism of the welding torch 4. To the side part of the base 1, the guides 5 are attached. The gearbox of the drive 2 has two output shafts on which the drum 6 for driving the carriage 3 and the drum 7 for driving the vibration mechanism of the welding torch 4 are rigidly fixed . Flex-bond - cable 8 is attached at one end to the cable. etke 3 and sent to the drive drum June 2, it covers more annular coils, is drawn to the unit 9 and encloses it. The other end of the cable 8 is also fixed on the carriage 3 from the reverse side. The cable 10 covers several turns of b araban 7, connects with block 11 (fig. 2), covers it with coil and yes-. Further, it is pulled to the block 12 (fig. 1) mounted on the plate of the end part of the guides 5, rounds it and connects with its other end (weaves). The carriage 3 consists of two cheeks connected by a spacer bushes 13 and screws 14 (Fig. 4) and is supported on the guides 3 by the rollers 15 (Figs. 1 and 4).

On the carriage 3, a mechanism for controlling the oscillation frequency of the welding torch 4 (Fig. 2) is mounted,

The cone 16 is mounted on a single shaft 17 with a disk 18, the shaft 17 is mounted on bearings in the support 19, mounted on the carriage 3.

This unit is equipped with a screw 22, at one end of which a roller 23 is fixed, which contacts the surface B with the surface a (Fig. 2) of the cone 16, and the other handwheel 24 and the locknut 25 are mounted.

On the welding torch 4, the support 26 is rigidly fixed, bearing the roller 27 in contact with the working surface S of the disk 18, and which with its axis 28 is embedded in the support sleeve 29 with the handwheel 30. The sleeve 29 is installed in the support 26 on bearings and has a groove 31 in which A pin 32 is built in, fixed on axis 28 of roller 27. Handwheel 33 is designed to move roller 27 over disk 18. Disk 18 has a surface B, inclined oi to the axis of rotation of shaft 17 and disk 18 itself. The roller 27 is pressed against the disc 18 by the spring 34 (FIG. 3), which at one end is connected to the support 35, which holds the welding torch 4, and the other is fixed on the carriage 3. The support 35 is fixed on the carriage 3 by means of a bracket 36 and an axis 37.

The device works as follows.

From the initial position, the armature 3 (FIG. 1) is displaced along the guides 5 by the actuator 2 by means of the drum 6, the cable 8 and the block 9. By rotating the drum 6 to one side or another, the carriage 3 is moved forward or backward (welding is performed in both parties).

The movement is transmitted to the oscillation mechanism of the welding torch 4 also from the drive 2, the drum 7, the cable 10, the blocks 11 and 12.

When the block 11 is rotated (Fig. 2), the roller 23 rotates with it, which contacts the surface S with the surface a of the cone 16. The roller 23 is rigidly connected to the screw 22, and the screw is connected to the shank 21 of the block 11 by a threaded connection and fixed by a lock nut 25 .

The cone 16 (FIG. 2) is fixed rigidly on the shaft 17 and through the shaft 17 removed - coupled to the disk 18. The rotation of block II is transmitted to the roller 23, and from there to the cone 16 and through the shaft 17 to the disk 18. surfaces & disk 18, support 26 together u; svlroch313

Noah burner 4 oscillates between {axis 37 axis (FNG. 3) floor by the action of the disk 18 and the spring 34.

The amplitude of oscillation of the roller 27 depends on its position relative to the axis of the disk 18. The greater the distance between the axis of the disk 18 and the contact point of the roller 27, the greater the amplitude of oscillation of the welding torch 4. The position of the roller 27 on the axis of rotation of the disk 18 does not create oscillatory movements of the welding torch 4. The repositioning of the roller 27 is carried out by turning the handwheel 33, while the thumbwheel 30 is kept away from rotating.

When the handwheel 33 is rotated, the axis 28 moves (the axis 28 is connected to the handwheel 33 by a threaded connection) progressively forward or backward as a result of the pin 32 interacting with the groove 31 of the sleeve 29.

Changing the position of the roller 23 (Fig. 2) relative to the surface of the cone 16 is performed by the handwheel 24.

- by unscrewing the locknut 25 manually rotate the handwheel 24, while the screw 22 rotates and moves relative to the threaded shank 21 of the block 11; the block 11 does not rotate (the block 11 is rotated by the drive 6 but since the rotational speed of the block 11 is small, when the handwheel 24 rotates, and with it the roller 23, practically the block 11 can be considered stationary), it is braked by the cable 10, associated with the gear drive 2 (figure 1). Thus, the movement of the roller 23 along the surface q of the cone 16 is made while the carriage 3 is moving, i.e. in the process of welding.

The roller 23 is any intermediate position between the extreme positions shown in FIG.

Moving the roller 23 to the tail of the cone 16 provides an increase in the oscillation frequency of the welding torch 4.

The device is designed to move only the carriage carrying the mouthpiece and the mechanism for adjusting the oscillation frequency of the welding torch, and the drive for the oscillation and movement mechanism of the carriage is stationary on the frame, which reduces the drive power.
