Safe stopping device, working method thereof and honing machine

Abstract

The invention relates to a safety stopping device, a working method thereof and a honing machine, the safety stopping device for the honing machine comprises a mechanical locking unit which is arranged at a top dead center position corresponding to a movement path of a sliding plate, and the mechanical locking unit is used for mechanically locking the sliding plate at the top dead center position. The speed change point detection unit is arranged at the position of a speed change point corresponding to the middle section of the motion path of the sliding plate and used for obtaining a signal that the sliding plate passes through the speed change point, and the static induction unit is arranged at the position of a lower dead center corresponding to the motion path of the sliding plate. And the static sensing unit is used for acquiring a signal that the sliding plate is static at the lower dead center position. The sliding plate can be stably, smoothly, accurately and reliably mechanically fixed at the top dead center.

Description

technical field [0001] The invention relates to the field of a honing machine and a stop device for the honing machine, in particular to a safety stop device, a working method thereof and a honing machine. Background technique [0002] When the piston ring is working, it is necessary to maintain a good seal between its outer circular surface and the cylinder liner during relative movement. Therefore, higher requirements are placed on the circularity and surface quality of the outer circular surface of the piston ring. The requirements on the roundness and surface quality of the outer surface of the piston ring. In the production and manufacture of the piston ring, the outer surface of the piston ring can be finished by the honing process. In the honing process, the piston ring reciprocates in the axial direction in the rotating honing cavity into which the honing agent is introduced, which produces an effect similar to plane grinding and improves the roundness and surface ro...

AI Technical Summary

Problems solved by technology

Existing honing machines either do not have position detection and top dead center stop functions, resulting in difficulties in loading and unloading and maintenance; or do not use mechanical stop methods, which are implemented from circuits or software, and there are potential safety hazards
