Abstract

The invention relates to chemical and galvanic processing of parts, in particular to equipment for fixing the workpieces. The invention consists in that the part 5 is mounted on the bracket 4 with the possibility of rotation around the axis of the suspension 11 and occupies a position in which the electrode 2 lags inside part 5.2 ill.

Description

The invention relates to chemical and galvanic processing of parts, in particular to equipment for fixing workpieces

An object of the invention is to increase productivity by eliminating the mounting and dismounting of a part with an electrode outside the bath.

Figure 1 shows a General view of the device with the workpiece; figure 2 - suspension with the part in the transported position.

A device for electrochemical processing of hollow parts with a bottom includes an electrolyte bath 1, an electrode 2 with a current-carrying bus, a suspension 3 on an arm 4 of which a workpiece 5 is mounted.

The device operates as follows .-.

The workpiece 5 (Figs. 1, 2) is attached with its bottom to the bracket 4 of the suspension 3. The operator picks up the suspension 3 by the grips of the movable frame 6 (Fig. 1), which, from the action of the dead weight of the suspension frame, moves up to the stop of the fingers 7 of the frame in the grooves 9 cheeks pendants. In this case, the rod 9 mounted on the lower cross member 10 of the movable frame b rotates the bracket 4 to the upper (transport) position. Next, the suspension 3 with the part 5 is lowered by the auto-operator and the bath with electrolyte and mounted on the support-catchers. The movable frame 6, freed from the operator’s grips, moves downward under the influence of its own weight, while the part 5 is fixed to the suspension bracket 4 at the same time, immersed in the electrolyte, rotates around the axis of the suspension 11 and will take its lowest position at which the electrode 2 is located

lies inside the workpiece 5. In this position, the part 5 will be positioned at an angle to allow air to escape from the internal cavity of the part. At the end of the electrochemical treatment of the inner surface of the part, the power supply is cut off. The auto operator picks up the suspension by the grips of the movable frame 6, which, under the influence of its own weight, moves upward and the bracket 4 with the part 5 also rises to the upper position by means of the tie rod 9 and the electrolyte is completely removed from the workpiece. After that, the inner surface of the part is thoroughly washed with water through a shower,

Thus, the use of a device for electrochemical processing of hollow parts with a bottom will increase productivity by eliminating the mounting and dismounting of the part with the electrode outside the bath.
