A device for removing burrs from the opening edge of a piston ring

Abstract

The invention discloses a piston ring opening edge burr removing device which comprises a burr removing disc base, a burr removing disc and a tool rest mechanism. The upper end face of the burr removing disc base is slidably connected with the lower end face of the burr removing disc, and the tool rest mechanism is fixedly connected to the back end face of the burr removing disc base; the back end of the burr removing disc is provided with a working opening of which the position corresponds to that of the tool rest mechanism arranged at the back side of the burr removing disc; an upper tool rest and a lower tool rest of the tool rest mechanism are provided with an upper grinding device and a lower grinding device, and the upper grinding device and the lower grinding device correspond to the upper edge and the lower edge of an opening of a piston ring placed in the burr removing disc. According to the piston ring opening edge burr removing device, the piston ring is installed in the burr removing disc, the burr removing disc is pushed to enable the four edges of the opening of the piston ring to rub against the tool grinding devices, edge burrs are ground off through the grinding effect of the tool grinding devices under the moderate friction force, therefore, the effect of removing the four edge burrs of the opening of the piston ring at a time is achieved, the workload of operators is reduced, the problem that burr removing is not uniform is solved, and the product quality and the production efficiency are improved.

Description

technical field [0001] The invention relates to a device for removing burrs from the opening edge of a piston ring. Background technique [0002] The piston ring is a key part of the internal combustion engine, and together with the piston and the cylinder liner, it forms a pair of friction matching pairs. There are strict quality requirements for the rings, especially the open end of the piston ring, which requires no burrs. Otherwise, the burrs will fall and become embedded in the friction surface between the piston ring and the piston, and between the piston ring and the cylinder liner and become abrasive particles, resulting in aggravated wear. [0003] In order to ensure the high quality of piston rings, the piston ring processing process is long, with a total of about 30 processes. Different processing processes are adopted according to the types, materials and uses of piston rings. Among them, the machining processes such as turning, milling, and grinding are divided ...
