Description

prism for centering the pen and the wedge, while the movable sponge is mounted on the rod, interacting through the spring with the pusher, the wedge is installed between the rollers with the ability to act on them, in addition, the feeder pen can be made in the form of a rotary disc with slots for fixing feathers, equipped with spring-loaded crackers.

FIG. 1 shows the proposed device, a general view; FIG. 2 is a kinematic diagram of the device; FIG. 3, a feather locking mechanism; a cross-section along AA in FIG. one; FIG. 4 shows a nest for fixing the pen, a section along BB in FIG. 3

On the base 1, a feather feed mechanism 2, a fixation mechanism 3, a vibrating hopper 4 with balls connected to each other through a cam drive 5, and a fixed jaw 6, which is used for fixing, are mounted.

The feeder mechanism 2 consists of a housing 7, through which the shaft 8 passes with a disk 9 fixed on it with sockets 1O, each of which has a housing 11 in which there are two crackers 12 and springs 13 each.

At the lower end of the shaft 8, a ratchet mechanism 14 is fixed, kinematically connected with the cam drive 5 and performing a discrete movement of the feather feed mechanism.

The fixing mechanism 3 of the pen consists of a body 15 in which guides 16 are mounted for moving the holder 17 with a wedge 18 acting through the rollers 19 on the pusher 2O, one of which is fixed on the body 15 and the other on the pusher 2O. the spring 21 presses against the plate 22 associated with the rod 23 passing through the sleeve 24 of the housing 15; and a movable sponge 25 is fixed to the rod 23 with two clamping pins 26 serving to precisely position the pen in the welding position, while the pen is clamped between the movable sponge 25 and the fixed sponge 6, where the sponge 25 simultaneously serves as a current-carrying element.

On the holder 17, a spring-loaded prism 27 is installed, centering the pen with respect to the clamping strips 26. The springs 28 serve to return the locking mechanism of the pen 3 to its original position.

The device works as follows. The pen is freely mounted in the recess 10 of the pen feed mechanism 2, which, discretely rotated, transfers the pen to the weld zone. At the same time, the vibration hopper 4, kinematically associated with the pen feeding mechanism, is rotated when

gear assistance 29, and transfers the ball to the weld zone.

The holder 17 of the mechanism 3 under the action of the cam actuator 5 begins to move down along the guides 16, and the wedge 18 fixed on it through the rollers 19 moves the pusher 2O, which pushes the plate 22 through the spring 21 and at the same time drives the rod 28 connected with it, on which is fixed a sponge 25

with clamping pins 26. Next, a fixation of the pen between the sponge 25 and the fixed sponge 6 placed on the base 1 occurs. Simultaneously fixed on the holder 17, the prism 27 acts on

feather, pushing it between the spring-loaded breadcrumbs 12 nests 1O on the pins 26, thus centering and installing the pen.

Vibrating hopper 4 carries out docking

a ball with a feather during welding, simultaneously giving a signal to turn on the supply of protective gas to the welding zone and turn on the welding cycle controller, which automatically maintains the necessary parameters of the welding process.

After the end of the welding, the pen locking mechanism 3 springs 29 returns to its original position, releasing the pen, and the pen feeding mechanism 2 transports

its on the load position. The cycle is automatically repeated.
