Description

The invention relates to equipment for welding in a ceiling position and is an improvement of the invention according to the author. Ev, No. 1232418.

The aim of the invention is to expand the technological capabilities of the device and improve the quality of welding.

Figure 1 presents the proposed device, a longitudinal section; figure 2 - section aa in figure 1.

The device contains a hollow two-arm lever I, freely suspended on axis 2. Flux-bin 4 is fixed to one arm of lever 1 through hinge 3. Copier wheels 5 and 6, cup 7, device 8 for feeding flux with drive 9 are fixed on flux-bin 4. the lever 1 is mounted the blocks 10 and 11, the cargo rope 12, the counterweight 13, the feed mechanism 14, the guide channel 15 for the electrode wire.

The axis 2 of the two shoulders lever is fixed on the carriage 16 of the vertical support 17, which is pivotally connected to the pneumatic actuator 18. On the carriage 16, the bracket 19 is fixed, on which the copier wheel 20 is mounted.

clone pad 23, which is spring loaded by compression spring 24. In the front part (Fig. And 2) of the inclined platform g are placed two adjustable copying element 25.

The device works as follows.

At the start of welding, the pneumatic actuator 18 is turned on, which presses the carriage 16 until the wheels 20, 5 and 6 and the copying elements 25 contact the outer surface of the product to be welded. The drive 15 of the device 9 for flux feeding 8 and the feeding mechanism 14, the welding circuit, the product rotator are turned on.

During the welding process, due to the constant self-regulating pressure of the pneumatic actuator 18, the wheels 20, 5 and 6 copy the surface of the product. At the same time, both copying elements 25 also constantly abut against the surface of the product 25 under the action of the springs 24 and the self-adjusting securing of the inclined platform in the cup. At the same time, the relative position of the flux bin and the inclined platform 0 relative to the joint of the product being welded is maintained. After welding, the pneumatic actuator 18 removes the device from the product 26.
