Изобретение относитс к электрофизическим и электрохимическим методам обработки и, в частности, касаетс устройства дл регулировани межэлектродиого зазора при электрохимической обработке.The invention relates to electrophysical and electrochemical processing methods and, in particular, relates to a device for adjusting the inter-electrode gap during electrochemical processing.

Известно устройство дл регулировани меж.электродного зазора, содержащее электромеханическую систему с направл ющей, на кронштейне которой установлен электроконтактный датчик, измерительный стержень которого контактирует с толкателем, жестко св занным с шшолью привода подачи электрода-инструмента 1.A device for adjusting the inter-electrode gap is known, comprising an electromechanical system with a guide, on the arm of which there is an electrocontact sensor, the measuring rod of which is in contact with the pusher rigidly connected with the drive-drive power-supply drive beam 1.

Недостатком известного устройства вл етс то, что при отводе электрода-инструмента на зазор до сра-батывани электроконтактного датчика возможно самопроизвольное перемещение пластины с электроконтактными датчиками направл ющей вниз под воздействием собственного веса, что приводит к искажению величины заданного межэлектродного зазора.A disadvantage of the known device is that when the electrode tool is retracted to the gap before the electrocontact sensor is spun, it is possible to spontaneously move the plate with the electrocontact sensors of the guide downward under the influence of its own weight, which leads to a distortion of the value of the specified interelectrode gap.

Целью изобретени вл етс повышение надежности работы устройства.The aim of the invention is to improve the reliability of the device.

Указанна цель достигаетс тем, чго электромеханическа система снабжена ползуном с размещенными на нем пилкой и электромагнитным фиксатором его положени , устаноппсиными в направл ющей, жестко ф1{ксировал1 он относительно пинолн привода подачи, электромагнитный фиксатор вьтолнеп в BHJJC рычага второго рода с тормозным штифтом. и качающимс коромыслом с регулируемглми верхним и нижним упора ш на обоих плечах. одно из плеч коромысла св зано пруж1шой с кронштейном, причем верхний упор предназначен дл взаимодействи с измерительным стержнем электроко.нтактного датчика, а шжний - с вилкой ползуна.This goal is achieved by the fact that the electromechanical system is equipped with a slider with a saw placed on it and an electromagnetic lock of its position, installed in a guide, rigidly F1 {x1, relative to the pinnac of the feed drive, an electromagnetic lock of the second kind of BHJJC lever with a brake pin. and swinging arm with an adjustable upper and lower stop w on both shoulders. One of the arms of the rocker arm is connected with the bracket, the upper stop is designed to interact with the measuring rod of the electro-contact sensor, and the other with the slide plug.

На фиг. 1 изображено устройство дл регулировани межэлектродного зазора; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows a device for adjusting the interelectrode gap; in fig. 2 shows section A-A in FIG. one.

Claims

The device for adjusting the interelectrode gap contains a device 1e on the bracket 1 of a pin 2 of the feed drive, a rocker pusher 3 with adjustable upper and two stops 4 and S on both shoulders, one of the arms of which is connected 39 by a spring 6 with the bracket 1, and an electrical contact sensor J, a measuring rod 8 for switching the contact group, interacting with the stop 4 of the balance arms of the body 3. The contact sensor 7 has micrometric screws 9 for adjusting the position of its contact group. The bracket 1 also has adjustable eccentric stops 10, which serve to limit the swing angle of the rocker arm 3. On the feed drive case, there are guides I, in which is placed the slide 12, which interacts with the surfaces of the fork 13. The slide 12 is equipped with an electromagnetic brake consisting of the electromagnet 14 and the lever of the second kind 15 with the brake pin 16. The device operates as follows. After installation, parts on the desktop include the supply of the electrode tool. Pinot 2 with a power tool moves forward, while the rocker-pusher 3 uses the bottom stop 5 to move the slider 12 along the guides 11. When the electric tool touches the workpiece, the electromagnet 14 is activated, attracts the lever 15 and locks the slider 12 in the guides 11. command to challenge ;; pintles 2. When reversing the motion, the pintles 2 release the swinging tiller 3 and, turning with the help of spring 6 around its axis, the adjustable upper stop 4 acts on the measuring rod 8 of sensor 7, toggle its contact group and giving the command to stop the removal of quills

2. The amount of retraction of the quill 2 to the interelectrode gap is determined by the position of the contacts of the electromagnetic sensor 7 moved by micrometric screws 9. After the processing is completed, the feed drive quill 2 returns to its original position and the rocker pusher 3 by the lower abutment 5 entering the slot 13 of the slider 12 s a gap sufficient to trigger the electrocontact sensor 7 moves the slider / 12 to the initial position. The swing angle of the rocker 3 is adjusted by the eccentric stops 10 and adjusted so that the amount of movement of the upper stop 4 would not exceed the free stroke of the rod 8 of the electrocontact sensor 7. Invention device A device for controlling the interelectrode ejector, made in the form of an electromechanical system a guide, on the arm of which there is an electrocontact sensor, the measuring rod of which has the possibility of contact with the push-rod, which is rigidly connected with the drive pinhole Electrode-tool, characterized in that, in order to increase the reliability of operation, the electromechanical system is equipped with a slide with a fork placed on it and an electromagnetic lock of its position installed in a guide rigidly fixed relative to the feed drive quill, and the electromagnetic lock is designed as a lever of the second kind with brake pads and a rocker arm with adjustable upper and lower stops on both shoulders, one of the arms of the rocker arm is connected by a spring with a bracket, with the upper minutes abutment intended for engagement with the dipstick electric contact sensor, and the bottom - with a slide fork.
