Abstract

The invention discloses an overall hole boring machining positioning mechanism for a connection rod large head hole. The positioning mechanism comprises a hydraulic cylinder, a fixing plate and a baffle; the baffle is arranged between the fixing plate and a hole boring tool bit; the portion, corresponding to the hole boring tool bit, on the baffle is provided with an avoiding through hole; the fixing plate is located between the hydraulic cylinder and the baffle; a movable pressing block used for pressing the large head end of a connection rod body and a connection rod cover onto the baffle isarranged in the portion, corresponding to the avoiding through hole, of the fixing plate; and the movable pressing block is arranged corresponding to a piston head of the hydraulic cylinder. The connection rod body and the connection rod cover are combined together to machine the connection rod large head hole, the connection rod large head hole is machined as a whole at a time, the large head hole portions corresponding to the connection rod body and the connection rod cover are consistent in size precision, and the product quality and the machining efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of engine connecting rod processing, in particular to a positioning mechanism for overall boring processing of big 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 pro...
