A through-hole device for castings

Abstract

The invention provides a through-hole device for castings. The through-hole device includes a cylinder, a bracket III, a guide rail, a moving plate III and a through-hole mechanism. The two ends of the guide rail are respectively provided with a limit plate and a support mechanism. The support mechanism includes a limit plate and a support mechanism. Position frame and limit assembly, the limit assembly includes a support plate and a limit ring, one side of the moving plate III is provided with a top plate; the output end of the cylinder is connected to the inner side of the top plate, and the through hole mechanism includes a through hole assembly and a through needle, The through-hole component includes a connecting plate, a sliding plate and a fixed plate. The connecting plate is fixed on the side of the moving plate III away from the top plate. The sliding plate is set under the connecting plate and can slide along the guide rail. The needle includes a needle bar and a needle head. One end of the needle bar is connected to the output end of the motor VI, and the other end of the needle bar is connected to the needle head after passing through the limit hole and the limit ring in turn. The through hole device can effectively remove the casting Impurities in the inner hole of the casting can be removed to ensure the normal use of the casting.

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...
