Digital controlled lathe for processing engine crank shaft connecting rod

Abstract

The invention relates to a digital controlled lathe for processing an engine crank shaft connecting rod. The lathe comprises a lathe base, a four-shaft linkage system controller, a first servo motor, a front rotating machine body, a turntable, a turning machine surface guide rail, a turning machine surface guide sleeve, a first lead screw, a lead screw fixing element, a cutter frame guide rail, a cutter fixing seat, second servo motors, a cutter handle, turning cutters, a second lead screw, a transmission shaft, a back following machine body and a turning machine surface. The servo motors are controlled to rotate by the four-shaft linkage system controller, so the turning machine surface is indirectly driven to leftwards and rightwards move, the axial processing dimension of the crank shaft connecting rod is realized, the two front and back second servo motors are controlled to rotate so that the front and back turning cutters are indirectly driven to forwards and backwards move, and the radial processing dimension of the crank shaft connecting rod is realized. The digital controlled lathe has the advantages that a digital controlled operation system is adopted for replacing an original hydraulic system, the operation is simple and convenient, the work efficiency is high, the processing dimension consistency is improved, and the equipment fault repair rate and the processing cost are reduced.

Description

[0001] technical field [0002] The invention relates to mechanical processing equipment, in particular to a numerically controlled lathe for processing engine crankshaft connecting rods. Background technique [0003] The engine crankshaft is an important part of the engine next to the cylinder block. Its processing quality directly affects the overall performance of the engine, and the connecting rod journal is an important part of the crankshaft. Therefore, the processing quality of the connecting rod journal directly affects the performance of the engine. . Traditional processing lathes are controlled by hydraulic systems, and the axial distance of each connecting rod is guaranteed by fixed length. It is necessary to manually replace and process different connecting rods, which is not only inefficient, time-consuming and laborious, but also the shape and position tolerance of a single connecting rod and the axis The axial distance cannot be guaranteed, the consistency of...

Problems solved by technology

Traditional processing lathes are controlled by hydraulic systems, and the axial distance of each connecting rod is guaranteed by fixed length. It is necessary to manually replace and process different connecting rods, which is not only inefficient, time-consuming and laborious, but also the shape and position tolerance of a single connecting rod and the axis The axial distance cannot be guaranteed, there is a large gap in the consistency of multiple connecting rods, and the hydraulic system is greatly affected by the ambient temperature, which has long been a bottleneck problem that has restricted the processing quality and production efficiency of crankshaft connecting rods.
