Rotary drum turning and clamping device for electric locomotive position change-over switch

Abstract

The invention relates to a rotary drum turning and clamping device for an electric locomotive position change-over switch. According to the technical scheme, the rotary drum turning and clamping device comprises an auxiliary clamping main shaft, wherein the auxiliary clamping main shaft is connected with a turning machine tool in a clamping mode; one side of the auxiliary clamping main shaft is detachably connected with a limiting ring; the outer side of the auxiliary clamping main shaft is sequentially connected with a plurality of rotary drums in a penetrating and sleeving mode; the other side of the auxiliary clamping main shaft is connected with a hexagon thin nut through threads; and the auxiliary clamping main shaft assists in clamping a plurality of rotary drums, is connected with a lathe and is used for turning the outer rings of the rotary drums. The rotary drum turning and clamping device has the beneficial effects that the rotary drum assembling and turning procedures of the position change-over switch are optimized, the rotary drum assembling and turning quality of the position change-over switch is improved, the rotary drum assembling and machining precision of the position change-over switch is improved, machining difficulty caused by intermittent turning of a slender shaft and non-ferrous metal during rotary drum assembling and turning is avoided, and the roughness of the processed surface meets the maintenance process requirements of the electric locomotive position change-over switch.

Description

technical field [0001] The invention belongs to the technical field of overhauling equipment for a position changeover switch of an electric locomotive, and relates to a turning and clamping device for a drum of a position changeover switch of an electric locomotive. Background technique [0002] During the overhaul process of the SS series electric locomotive position switch, the locomotive overhaul regulations have clear requirements on the thickness of drum assembly drum. Turning must be carried out, and the design structure of the drum assembly is a slender shaft, and the structure of the drum is irregular, and the material is copper. In the field of turning, the slender shaft and non-ferrous metal intermittent turning will cause severe vibration and difficult processing, and there is no guarantee after turning. roughness requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and...
