The big and small head boring integrated machining equipment for the engine connecting rod has the advantages of high working efficiency, higher machining precision and lower rejection rate.

Description

technical field [0001] The invention relates to the technical field of engine components, in particular to integrated processing equipment for engine connecting rods, large and small heads, and bores. Background technique [0002] The connecting rod is an important part in the automobile engine. It connects the piston and the crankshaft. Its function is to convert the reciprocating motion of the piston into the rotational motion of the crankshaft, and transmit the force acting on the piston to the crankshaft to output power. The main damage forms of connecting rods are fatigue fracture and excessive deformation. The working conditions of the connecting rod require the connecting rod to have high strength and fatigue resistance, and also require sufficient rigidity and toughness. Therefore, strict requirements are required on the shape of the connecting rod, excessive fillets, etc., and attention should also be paid to the surface processing quality and Improve fatigue stren...

AI Technical Summary

Problems solved by technology

[0003] In the existing engine connecting rod, the large and small head hole borings are processed separately in two processes, and the production efficiency is low; in addition, when the large and small head bores are chamfered, the angle of the connecting rod needs to be changed, and the work efficiency is low. The performance requirements are relatively high; when the boring tool is processing the connecting rod, the distance between the boring tool and the connecting rod to be processed should be controlled in place to improve the machining accuracy and reduce the scrap rate
