Special machine tool for press mounting of camshaft bush of diesel engine

Abstract

The invention provides a special machine tool for press mounting of a camshaft bush of a diesel engine, which can be used for solving the problems of high labor intensity of workers low production efficiency in the traditional press mounting process of a camshaft bush which is realized through manually knocking a mandril with an iron hammer, and has the beneficial effects of effectively reducing the damage to the camshaft bush and tool loss during press mounting process, lowering the machining cost, and improving the press mounting precision of the camshaft bush. The special machine tool is characterized by comprising a front engine base, a rear engine base, a hydraulic cylinder, an operation box and a PLC (Programmable Logic Controller) system, wherein the operation box and the hydraulic cylinder are both connected with an electric cabinet by the PLC electronic control system, the front engine base and the rear engine base are connected by a bolt, a tailstock is arranged on the front end part of the front engine base by a bolt, a limiting stopper and a positioning plate are further arranged on the front engine base, the hydraulic cylinder is fixed on the rear engine base respectively by a front footstand and a rear footstand of the hydraulic cylinder, a piston rod head of the hydraulic cylinder is in threaded connection with a pressure head, a guide bush is sheathed at the front end of the pressure head in an loose manner, and the operation box is arranged on the rear engine base by a vertical post.

Description

technical field [0001] The invention relates to the technical field of processing equipment for diesel engines, in particular to a special machine tool for press-fitting a camshaft bushing of a diesel engine. Background technique [0002] In the production process of the multi-cylinder diesel engine block, there is a process of press-fitting the camshaft bushing, that is, the camshaft sliding bearing of powder metallurgy material (commonly known as the camshaft bushing) is pressed into the specified position of the bottom hole of the camshaft of the diesel engine block. In the past, the press-fitting camshaft bushings were mostly assembled by manually hitting the mandrel with a hammer, which had the problems of high labor intensity and low production efficiency, and the bushing was prone to bushing cracking and The problem that the press-fitting tool is damaged and the processing cost is high, so it cannot meet the production requirements of large-scale multi-cylinder diesel...

AI Technical Summary

Problems solved by technology

[0003] In view of the above problems, the present invention provides a special machine tool for press-fitting diesel engine camshaft bushings, which can solve the labor intensity of workers existing in the process of manually hitting the mandrel with a hammer to press-fit camshaft bushings. Large size and low production efficiency, and can effectively reduce the damage to the camshaft bushing and the loss of tooling during the press-fitting process, reduce processing costs, and improve the press-fitting accuracy of the camshaft bushing
