A feeding device for a large-diameter circular machine for piston rings

Abstract

The invention provides a piston ring major-diameter circling machine feeding device which is composed of a main driving shaft assembly, a gap bridge shaft assembly and a locating shaft assembly. The main driving shaft assembly comprises a main driving shaft and a main driving gear arranged on the main driving shaft in a sleeved mode. The gap bridge shaft assembly comprises a gap bridge shaft and a gap bridge gear arranged on the gap bridge shaft in a sleeved mode. The locating shaft assembly comprises a locating shaft and a locating gear arranged on the locating shaft in a sleeved mode. The locating gear is meshed with the gap bridge gear, the gap bridge gear is meshed with the main driving gear, and the main driving gear is meshed with a motor gear. The piston ring major-diameter circling machine feeding device is simple in structure, the motor gear drives the locating gear to drive through the main driving gear and the gap bridge gear, therefore, rotation speeds of a motor can be transited onto the locating gear smoothly, stability of circling steel belts in the conveying process is improved, and the steel belts can carry out circling stably after the steel belts are pushed by a locating pressing wheel to enter a circling system. Thus, circling accuracy of the steel belts can be improved, and sizes of circled piston rings can be guaranteed to be uniform.

Description

technical field [0001] The invention relates to the technical field of circular winding machines, in particular to a large-diameter circular circular machine feeding device for piston rings. Background technique [0002] Piston ring large-diameter circular winding machine is a special machine tool for producing steel piston rings for internal combustion engines. The feed device of the circular machine currently used in the market, the motor gear is directly connected to the upper and lower transmission box connecting rod shafts, and the positioning pressure roller is driven to rotate through the conveying steel belt, which will easily cause the positioning pressure roller to vibrate and run uncoordinated , it is difficult to control the feeding speed of the positioning roller, and the stability of the round steel belt cannot be guaranteed. When the steel belt is rounded, it will be out of round, the rounding accuracy is low, the size of the continuously wound piston rings is...
