Abstract

This invention relates to the field of electrochemical machining of predominantly flat parts. The purpose of the invention is the expansion of technological capabilities and increased reliability. During operation, due to non-uniform: deformation of the sleeve 5, a reliable electrical contact of the current supply with the surface of the workpiece 6 is ensured while maintaining the protection of the current supply against processing materials. Such a design allows the processing of a wide range of parts and the use of advanced technology, which in general expands the technological capabilities of the suspension, 3 cells. with joint venture co oo 4 sfie. /

Description

The invention relates to electrochemical machining, the advantage of highly flat parts, in particular printed printing.

The purpose of the invention is to expand the technological capabilities of the suspension and improve reliability.

Fig "1 shows the proposed suspension; in Fig.2 a section along the axis of the suspension; ngg fig.Z - the same, when fastening parts of increased thickness, the pendant contains levers 1 with jaws in the form of jaws 2, which are filled together with levers and compressive spring 3. In the holes of 4 jaws, one 5SONT mounted sleeves 5 of elas- Typically from the material with corrugations arranged parallel to the free end of the bush, facing the processed degali 5, the last corrugation 7 of the sleeve 5 forms a recess 8 in which the current lead 9 is attached The current lead 9 is connected to the current lead 9

Suspension works as follows.

By squeezing the ends of the levers 1, the conductor 9 is diluted and the workpiece 6 is inserted between them then released. The ends of the levers 1, Under the action of springs 3 sponges 2 with bushings 5 installed in their holes, converge from the beginning): (and the last corrugation 7 sleeves, fit the surface of the part 6 to be treated, deform; to form a closed volume between the surface of the part and the recess 8. Then there is a pressing of the current lead ic on the surface of the workpiece b and further deformation of the corrugations of the bushings 5 in parallel to the equilibrium junction TOj: rjiTH between the elastic deformation forces of 1 tuloc 5 and the springs 3. As a result

those machined part securely

is fixed in the suspension, between the side working parts, on the surface: the remaining part 6 and the current lead 9 form a reliable electrical contact, and the current lead 9 is protected from the influence of the material that the part is machined

In the case of machining a part with deviations from parallelism of the surface shea of different thickness (Fig. 3),

Suspension for electro-machining of parts, combined levers with der 1 killer bushings, fastened with the possibility of

characterized in order to expand those possibilities and the sleeve of the sleeve are made of elating material laid parallel to the end of the sleeve in which it is mounted.

the sleeve 5 due to its implementation of an elastic material with corrugations has the ability to self-securely clamping the current lead 9 to the part surface all its contacting surface. At the same time, the current lead is not protected from the workpiece material

In comparison with the known, the proposed suspension is simple in its design, does not require high precision in the manufacture of parts, is reliable in operation,

In the known suspension, there are at least 12 main original parts, and in the proposed suspension there are 4 original parts out of a total of 7. Therefore, the proposed suspension has higher applicability and repeatability ratios.

The suspension can be used in an automated system for electrochemical machining of parts, since it is easily embedded in the manipulators due to the possibility of compensating the corrugated sleeve for the thickness and shape of the planes of the part being processed.
