Cylinder liner press fitting apparatus for diesel engine cylinder block and processing method thereof

Abstract

The present application belongs to the technical field of press fitting, and particularly relates to a device for cylinder liner conveying and press fitting, and more particularly to a cylinder liner press fitting device for a diesel engine cylinder body and a processing method thereof. The cylinder liner press fitting device for the diesel engine cylinder body comprises a feeding mechanism, a transfer mechanism and a press fitting mechanism. The feeding mechanism is provided with a plurality of conveying plates for conveying the cylinder liner. The conveying plates are provided with supporting protrusions. The supporting protrusions with cold air blowing function are arranged on the conveying plates. In the feeding and conveying process, the cylinder liner is blown by cold air to reduce the abrasion of the cylinder liner during feeding. In the transfer process, the cylinder liner is centered by cold air, so that the cylinder liner is coaxial with the supporting protrusions and the clamping part of the transfer mechanism. Before assembly, the cylinder liner is cold shrunk by cold air to reduce the interference between the cylinder liner and the cylinder body, so that the press fitting process is more stable, and the surface scratch of the cylinder liner is further reduced.
