Engine cylinder liner pressing machine

Abstract

The invention discloses an engine cylinder liner press and belongs to the field of machinery. The engine cylinder liner press comprises a base, a top seat, a rear pillar, a front pillar, a cylinder liner feeding mechanism, a cylinder feeding mechanism, a cylinder liner head pressing device and a positioning and carrying device. The front of the base is connected with the front of the top seat through the front pillar. The rear portion of the base is connected with the rear portion of the top seat through the rear pillar, the cylinder liner head pressing device is arranged below the top seat and fixedly connected with the same. The cylinder liner feeding mechanism is mounted on the inner side of the rear pillar. The feeding portion of a cylinder liner feeder in the cylinder liner feeding mechanism is arranged right below the cylinder liner head pressing device. The cylinder feeding mechanism and the positioning and carrying device are arranged on the base. Full-automatic feeding of cylinder liners and cylinders is realized, and high-precision automatic positioning and high carrying capacity of the cylinders can be achieved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, more specifically, to an engine cylinder liner press-in machine. Background technique [0002] The cylinder liner of the engine block is a key part of the engine. When the engine is working, the piston reciprocates in the cylinder. In order to improve the wear resistance of the cast iron cylinder bore, a thin-walled cylinder liner is pressed into the cylinder bore. The pressed thin-walled steel sleeve has high hardness, high surface quality and high wear resistance, which greatly improves the life of the engine. However, it is more difficult to press-fit such a thin-walled cylinder liner. Improper press-fitting will cause serious deformation of the inner hole of the cylinder liner, crush the cylinder liner, cause waste and affect the performance of the engine. In addition, most of the existing engine cylinder liner press-in machines are manually operated, and the productivity is low. [0003...

AI Technical Summary

Problems solved by technology

The structure of the assembly device of the diesel engine dry cylinder liner is simple and reasonable, and the press-fitting efficiency is improved by adopting a press-fitting machine and raceway transportation, but the application still has deficiencies: 1. The cylinder liner head cannot automatically take material, and It is easy to make the cylinder liner out of round; 2. The positioning accuracy of the cylinder body needs to be improved; 3. The force of the raceway is not considered when the raceway is used for transportation, and the bearing capacity of the device needs to be improved
