Through hole device for casting parts

Abstract

The invention provides a through hole device for casting parts. The through hole device comprises an air cylinder, a support III, a guide rail, a moving plate III and a through hole mechanism, the twoends of the guide rail are provided with a limiting plate and a supporting mechanism correspondingly, the supporting mechanism includes a limiting frame and a limiting assembly, the limiting assemblycomprises a supporting plate and a limiting ring, one side of the moving plate III is provided with a top plate, the output end of the air cylinder is connected with the inner side of the top plate,the through hole mechanism comprises a through hole assembly and a through pin, the through hole assembly comprises a connecting plate, a sliding plate and a fixing plate, the connecting plate is fixedly arranged on the side, away from the top plate, the moving plate III, the sliding plate is arranged below the connecting plate, the sliding plate can slide along the guide rail, the fixing plate isarranged above the connecting plate, the through pin comprises a needle bar and a needle head, one end of the needle bar is connected with the output end of a motor VI, and the other end of the needle bar is connected with the needle head after sequentially passing through the limiting hole and the limiting ring. The through hole device can effectively remove impurities in inner holes of the casting parts, and ensures normal use of the casting parts.

Description

technical field [0001] The invention relates to the technical field of casting processing, in particular to a through-hole device for castings. Background technique [0002] Inner hole parts (such as valve inner hole, engine connecting rod, cylinder liner, etc.) play an important role in mechanical motion coordination, and can be combined with outer circular parts to achieve relative motion and power transmission. Castings are castings obtained by pouring liquid metal into a casting cavity that is suitable for the shape of the part, and waiting for it to cool and solidify; on the one hand, castings with inner holes are prone to liquid metal overflow during the production process, resulting in castings The phenomenon of inner hole blockage, on the other hand, after the casting is produced, after a long period of placement, plus various handling during transportation, the inner hole of the casting will accumulate dust. When the dust accumulates to a certain extent It will aff...
