Abstract

The invention discloses a large shaft end keyway electrolytic machining device with high processing precision. A sealing case is mounted onto two guide keys and an assembling unit of an insulating guide body respectively through two keyways of a left shaft hole and a right shaft hole in a clearance sleeved manner; the insulating guide body is mounted onto a copper unit in a sleeving mode through casting, the left end of the insulating guide body is aligned to the left end of the copper unit, the right end of the insulating guide body is arranged inside the right end of the right shaft hole of the sealing case, and two radial holes and two external radial electrolyte inlet and outlet holes on the sides of the radial holes are aligned to and communicated with two bosses on the copper unit and two internal radial electrolyte inlet and outlet holes on the sides of the bosses respectively; the two bosses of the copper unit extend out of the two radial holes of the insulating guide body respectively, the left end of the copper unit is connected with the right end of a hose connector, the right end of the copper unit extends out of the right end of the sealing case, and the left end of the hose connector is connected with an electrolyte output hose; the left end of a connector is detachably connected with the right end of the copper unit of an electrolytic cathode, and a flange disc is detachably mounted on the right of the connector.

Description

technical field [0001] The invention belongs to an electrolytic machining device, in particular to an electrolytic machining device for a keyway at the end of a large shaft. Background technique [0002] There is a large shaft in some special mechanical equipment, see figure 1 with figure 2 , the large-scale shaft member 6 is more than 3 meters long, and is provided with an axially stepped through hole comprising a small-diameter part 6-3 and a large-diameter part 6-1 that communicate with each other, and at the right end of the large-diameter part 6-1 The inner wall is provided with two end key grooves 6-2 which are symmetrical to the axis of the axially stepped through hole and whose outer ends are open. The two end keyways 6-2 are designed to be non-penetrating and non-relief structures due to special needs, and cannot be processed by ordinary techniques such as slotting and planing. A better processing method is to perform electrolytic machining on them. At present, ...
