Abstract

The invention discloses a connecting rod big end hole integral machining device. The connecting rod big end hole integral machining device comprises a boring tool bit and a connecting rod positioningmechanism, and further comprises a bottom plate and a working cylinder used for driving the connecting rod positioning mechanism to move relative to the boring tool bit. The connecting rod positioningmechanism and the working cylinder are both arranged on the bottom plate. The connecting rod positioning mechanism is connected with a piston rod of the working cylinder. The connecting rod positioning mechanism comprises a hydraulic cylinder, a fixed plate and a baffle. The baffle is arranged between the fixed plate and the boring tool bit. The baffle is provided with a receding through hole corresponding to the boring tool bit. The fixed plate is located between the hydraulic cylinder and the baffle. A movable pressing block used for pressing the big end of a connecting rod body and a connecting rod cover onto the baffle is arranged in the position, corresponding to the receding through hole, of the fixed plate. The movable pressing block is arranged corresponding to a piston head of the hydraulic cylinder. The connecting rod big end hole integral machining device can conduct integral one-time machining on a connecting rod big end hole. The product quality is improved. The overall machining efficiency is substantially improved.

Description

technical field [0001] The invention relates to the technical field of connecting rods, in particular to a device for integrally processing large end holes of connecting rods. Background technique [0002] The connecting rod of the engine includes a matching connecting rod body and a connecting rod cover, and the cooperation of the connecting rod body and the connecting rod cover will form the big head hole of the connecting rod. At present, the big head hole of the connecting rod is processed separately, that is, the big head hole part of the connecting rod body and the connecting rod cover are processed separately, the processing efficiency is low, and the size consistency of the big head hole processing of the two parts is poor, which affects the quality of the connecting rod. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the technical problem to be solved by the present invention is to provide an integral processing device fo...
