Piston ring side positioning CNC grinding machine

Abstract

The invention discloses a piston ring side positioning numerically-controlled grinder which comprises a working platform, a grinding wheel, a discharging hole, a tapered feeding mechanism, a pressing servo motor, a pressure head, a to-be-machined ring, a pushing servo motor, a selector switch, a numerical control device and a discharging ring-arranging rod. The piston ring side positioning numerically-controlled grinder is controlled numerically, so that the purpose that a positioning R slot at the side is continuously and automatically ground by using a plurality of piston rings is realized, a proper pressure is always applied to the piston rings in a machining process by means of matching of a mechanical structure and electric control specially in a process of automatic feeding and discharging of continuous processing, the machining procedure completed by completely depending on manual work in the prior art is changed, full-automatic and continuous machining is realized, the consistency of process parameters is kept in a machining process, machining quality is ensured and improved, and working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a numerical control grinding machine for processing special piston rings, in particular to a numerical control grinding machine for side positioning of piston rings for processing R grooves used for side positioning of piston ring openings. Background technique [0002] The special machine for piston ring processing is a special machine tool for the internal combustion engine manufacturing industry. At present, the processing of side positioning piston ring—a special type of piston ring with R groove for positioning on the side of the piston ring opening—all relies on manual processing, and there is no complete set of equipment for this process. In the process of manual processing, it is necessary to rely on human hand feeling to press the ring on the working platform to ensure that the ring to be processed slides smoothly on the working platform, so that the side of the opening of the ring can be smoothly ground by the grindin...

AI Technical Summary

Problems solved by technology

At this time, the pressure on the ring should not be too large, too large will cause the ring to deform or cannot slide smoothly on the working platform; the pressure should not be too small, too small will cause the ring to warp and the processing size cannot be in place, and the life of the tooling will be shortened. short

Therefore, the products processed by hand are affected by human operation and tooling, with low efficiency, poor product quality consistency and high scrap rate.
