The invention relates to electrochemical machining and can be used for electrochemical marking of products from conductive materials.

A well-known tool for electrochemical marking [A.S. USSR №1060381, the IPC 23 R 1/04, 1983], equipped with a marking paste, conductive elements which are combined in the cells fixed on the dielectric rod, and form together with the last individual cell in the raster.

The main disadvantage of this tool is: the use of resins and adhesives for its manufacture, which emit harmful substances, and when grinding is also toxic dust.

A device for electrochemical marking conductive surfaces [A.S. USSR №516496, the IPC 23 R 1/04, 1976], conductive elements made in the form of blocks, forming horizontal and vertical (tilt) the series in the form of synthesizing marking sign.

The disadvantage of this tool is the difficulty and complexity of dismantling the device in case of instrument failure. A common shortcoming of these inventions is the design complexity, complex switching diagram.

Closest to the invention to the technical essence is the numerator [A.S. USSR №1066799, the IPC 25 N 7/04, 1984], which contains a base mounted on its housing with the Central the first hole and the longitudinal groove, placed in the Central bore of the housing stock, the shank of which is connected with a drive reciprocating motion, with the end of the block with spring-loaded in the axial direction of the punches, and placed in a longitudinal groove of a case head in the form of a set of numbered disks with teeth on the cylindrical surface, a ratchet mounted on the shaft retainers in the form of a spring interacting with the teeth of numbered discs, and spring-loaded to the ratchet pawl, kinematically connected with the rod and cooperating with the teeth of numbered disks. The shaft is made of longitudinal grooves on the end of each plate disc grooves underneath the tabs, which communicate with the longitudinal grooves, the first of the numbered disks rigidly connected with the ratchet on one of its ends and secondary drives on the same radius are made parallel to their axes of holes at the other ends of the secondary drive, opposite the holes, the holes, and the numerator is equipped with a terminal located in the first disk, balls, placed in the middle and last wheels and periodically interacting with one of the ends of the rod, and a Cam mounted on the side surface of the groove of the housing and interacting with others by the end of the rod.

In addition, the numerator is equipped with a ribbon plates, the associated gear rack placed with the possibility PE is Emesene in the housing perpendicular to the axis of the shaft, and interacting with her dog, installed on the stock.

The main disadvantage of this tool is: the complexity of the design and mechanism of the change of characters.

The task of the invention to increase processing performance through simplicity of design and reduced process time.

This task is achieved in that the electrode tool for electrochemical marking containing base that is installed in it with the ability to move the body and placed in the longitudinal groove of the housing case head in the form of a set of numbered disks with teeth on the cylindrical surface and accommodated in the housing, the mechanism of automatic change of sequence numbers containing the ratchet spring to him the dog and the clips mounted for engagement with the teeth of number of disks, in contrast to the prototype it is equipped with a spring to return the body to its original position, with the locking mechanism of the automatic change of sequence numbers is made in the form of gears fixed on the shaft in the housing, the teeth of which are arranged at an angle of 60° with the opportunity to interact with the teeth of the rotary drives installed with numbered disks and between the teeth number of disks is a dielectric, whose height exceeds the height of the tooth on the value of megaelectronvolts.

Figure 1 shows the proposed device, General view; figure 2 is a section a-a in figure 1; figure 3 - view of G in figure 2; figure 4 - section b-b In figure 3.

The electrode tool for electrochemical marking comprises a base 1 with a Central hole, in which is placed the handle 2 of the case 3 with a slide groove for reciprocating movement of the shaft 4 of the housing 3, and to return the case 3 in the initial position, the spring 5. At the base of the 1 is the hook 6. In the longitudinal groove of the housing 3 posted by composing the cylinder in the form of a set of numbered disks: the first 7, second 8, the third 9 and fourth 10 numbers on the teeth and dielectric 11 between the teeth of numbered disks on the shaft 4 has a ratchet with 12 teeth 13. The first latches 14, 15 second, third 16 in the form of gears are located on the same shaft 17 in the housing 3. The latch 14 is connected with the teeth 18 of the rotary disk 19 and the teeth 20 (not shown) of the rotary disk 21, the latch 15 with the teeth 22 (not shown) of the rotary disk 23 and the teeth 24 (not shown) of the rotary disc 25, the latch 16 with the teeth 26 of the rotary disk 27 and the teeth 28 (not shown) of the rotary disk 29 and the ratchet 12 is spring-loaded dog 30, insulated from the housing 3 and with the opportunity to interact with the teeth 13 of the ratchet 12. The dog 30 compound and has cutouts of different sizes; it prevents rotation of the ratchet 12 (and license plate of the disk 7 in the opposite direction. The first of the numbered disks 7 is rigidly connected with the ratchet 12 and the rotary disk 19, and the number of the disk 8 with the rotary discs 21, 23; number of disk 9 with the rotary disk 25, 27; and the number of the disk 9 with the rotary disk 29.

The electrode tool for electrochemical marking works as follows.

Before you begin album 7 put over a conductive item, pre-soaked in electrolyte, “1”, and the remaining numbered disks to “0”. On the base 1 is a positive potential, and the conductive shaft 4 is isolated from the base 1 is a negative potential. Then case 3 is lowered, the contact number of disks of the first 7, second 8, the third 9 and fourth 10 with the item is the process of marking the number “0001”. Reverse body 3 inside the base 1 is carried by the spring 5, and the hook 6 rotates the ratchet wheel 12 and with it the number of the disk 7 to about 1/10 of a turn and marking on the item becomes the next sign of the disk 7. When you contact process is marked “0002”. And so to “0009”. After the imprint “0009” teeth 18 of the rotary disk 19 engages with the gear-lock 14 and rotates together with the rotary disk 21 and numbered disk 8 to about 1/10 of a turn and fixes the disk 8 in this position due to the fact that the teeth of the gear-fixat the RA 14 are at an angle of 60 and the teeth of the rotary disk 21 includes them engaged. On disk number 7 on the item is “0”, and the disk number 8 is “1”, that is, the imprint “0010”, etc. Similarly rotated and the rest of the numbered disks.

The proposed device has a simple, rugged construction and convenient in operation. In addition, it has high performance and wide range of technological capabilities.
