Universal transmission tool for processing crosshead pin of marine diesel engine

Abstract

The invention provides a universal transmission tool for processing a crosshead pin of a marine diesel engine. The universal transmission tool is installed on a machine tool and is characterized by comprising a universal transmission rod, a chuck connecting plate and a universal transmission plate, wherein the chuck connecting plate is fixedly connected to the machine tool through an inner hexagon screw and a nut, the universal transmission plate is fixedly connected to the end surface of a crosshead pin through an inner hexagon screw and a nut, one end of the universal transmission rod is fixedly connected with the chuck connecting plate through a bolt and a nut, the other end of the universal transmission rod is fixedly connected with the universal transmission plate through a bolt and a nut, and the machine tool drives the crosshead pin to rotate through the chuck connecting plate, the universal transmission rod and the universal transmission plate in sequence. According to the invention, the universality and the mounting efficiency of the tool are greatly improved, the labor intensity is effectively reduced while the process cost is reduced, the machining quality is improved, and the tool has the advantages of being easy and convenient to operate on site and safe and reliable in performance and is also suitable for machining of various large shaft parts.

Description

technical field [0001] The invention relates to a process equipment for manufacturing a marine diesel engine, in particular to a general transmission tool for processing a crosshead pin of a marine diesel engine, and belongs to the technical field of mechanical processing. Background technique [0002] The crosshead pin is one of the important moving parts of the high-power low-speed marine diesel engine. It is heavy in weight, large in volume, high in surface precision, and has many types of models. The processing of crosshead pins on machine tools usually depends on technological equipment. The use of suitable and general-purpose tooling is the key to improving product quality and processing efficiency on the original basis. During the cylindrical grinding process of existing crosshead pins, for crosshead pins of different specifications, it is necessary to install their own dedicated transmission connecting plates, so there is a phenomenon of one model with one set of tra...
