Description

The invention relates to electrochemical metalworking machines. STS-anks for electrochemical deburring are known, containing a frame with a working table, several cathode devices, fixed parts of the working sockets are fixed on the working table, and moving on reciprocating installation movements of the drive rods 1. The disadvantage of these machines is limiting the working space when processing two detangs, for example, a rotor of pneumatic machines, in one cathode device, inconvenience of controlling the fixation of parts and revision of the cathode devices in the working position due to the presence idle positions for loading parts and inconvenience in operation, since the drive with the rod of the movable part of the cathode device is located in the upper part of the machine, which limits access to monitor and view the cathode devices in the working position. The aim of the invention is compactness and improvement of service conditions due to improvement of control conditions of workpieces and revision of cathode devices at working pc positions. This is achieved by the fact that the moving parts of at least two working sockets of the cathode devices are rigidly connected through a crossbar to a common drive rod, which is installed with the possibility of rotation of the axis between the fixed parts of the working sockets and the groove copier, which interacts with a guide roller mounted on the frame; the rod drive is placed on the working table and connected to the rod through a hinge. FIG. 1 shows the proposed machine, a general view; in fig. 2 - cathode device with a drive. The machine contains a bed 1 with a work table 2, on which there are cathode devices consisting of stationary parts 3 with moving parts 4 fixed on the rod 5 of the drive 6. The drive 6 is located under the work table 2. The stationary part 3 of the cathode devices contains working 7 slots for machined parts 8, each of which has an orientator 9 and a fi-scale 10 mounted. Between the working slots 7 there is a guide hole 11 through which the rod 5 of the actuator 6 is passed. The rod 5 is equipped with a groove-copier 12, which interacts guide roller 13, Formation on the frame, to provide upon application of axial LOAD ki to the rod of the actuator rectilinear movement and turning it around its axis moving portion 4 of the cathode relative to the stationary part of the device 3 for releasing the working space. For the final assembly of the Movable 4 and the stationary 3 parts, each cathode device, guides are provided. Fingers located on the stationary part 3 and retaining points J14 with clamps 15 located on the movable part 4. The machine works as follows. Machined parts 8 are installed in the working slots 7 of the fixed part 3 of the cathode device, are oriented by orientators 9 and fixed by locks 10. When the drive 6 is turned on, the rod 5 moves under the action of the axial load from the drive in the vertical direction up responses stie guide 11. In this case, the rod 5 due to the copier-groove 12 and the guide roller 13 rotates about its axis, whereby the movable portion 4 and the cathode unit is rotated relative to the fixed part around its axis. With further axial movement of the rod 5, the sleeve 14 of the movable part 4 of the cathode device enters the retainer 15 of the fixed part 3, with the result that the movable part 4 and the fixed part 3 of each cathode device. are combined, i.e. brought into position. At the end of processing, the actuator 6, moving the rod 5 in the opposite direction, returns the movable part 4 of the cathode-1HE device to its initial position, thereby freeing the working space for removing the machined part and for setting the next one. of the invention. An electrochemical deburring machine comprising a bed with a work table, several cathode devices, fixed parts of the KOTOfftix work jacks are fixed on the work table, and movable ones on reciprocating installation movements of the drive rods, characterized in that, for the purpose of compactness and improving the conditions of service by improving the conditions of control of the processed chips and revision of the cathode devices at the working positions, the moving parts of at least two working sockets of the cathode The cross-beams are rigidly connected with the common drive rod, installed with the possibility of rotation about its axis between the fixed parts of the working jacks and the groove-copier, which interacts with the guide roller mounted on the frame, on the cylindrical surface, and the rod drive is placed under the working table and connected to the stem through the hinge.
