Abstract

The invention relates to the field of grinding machining, in particular to special-shaped casting inner surface grinding equipment which comprises a center shaft, a grinding mechanism and an adjusting mechanism, the center shaft extends in the left-right direction, and the center shaft is driven by an external driving element to rotate and feed from right to left; each polishing mechanism comprises two polishing units, when the polishing units rotate along with the center shaft and the diameters of the inner surfaces of the castings are different, the swing amplitudes of swing arms of the two polishing units are different, the adjusting mechanisms enable the mass centers of the polishing units with the large swing amplitudes to be closer to the center shaft, and the acting force of the polishing units on the inner surfaces of the castings is reduced by reducing the centrifugal force of the polishing units. Therefore, the grinding amount of the grinding unit on the inner surface of the casting is reduced; and the adjusting mechanism enables the mass center of the polishing unit with the small swing amplitude to be farther away from the center shaft, the acting force of the polishing unit on the inner surface of the casting is increased by increasing the centrifugal force of the polishing unit, and therefore the grinding amount of the polishing unit on the inner surface of the casting is increased, and the deformation degree of the inner surface of the casting is overall reduced.

Description

technical field [0001] The invention relates to the field of grinding and processing, in particular to an inner surface grinding device of a special-shaped casting. Background technique [0002] The surface of the casting is rough and uneven after the preliminary production is completed, and it needs to be ground to produce the finished product. Generally, it is mainly ground by an electric grinding machine. When grinding the inner surface of special-shaped castings, such as conical castings, a rotary grinding is required. The mechanism is ground to ensure the roundness of the inner hole. In the prior art, the Chinese invention patent with the authorization announcement number CN110732920B discloses a centrifugal polishing device for the inner hole of a casting, which uses the grinding rod to rotate under the centrifugal action. Swing makes the grinding ball at the end of the grinding rod abut, and when the grinding ball rotates with the grinding rod, it grinds the rotating ...
