Center hole positioning wheel set press machine

Abstract

The invention discloses a central hole positioning wheel pair press mounting machine, which comprises a machine frame, an oil tank device, thimble devices, a trolley, a detection device, a hydraulic system and an electronic control system, wherein the oil tank device, the thimble device, the trolley, the detection device, the hydraulic system and the electronic control system are axially and symmetrically arranged in the machine frame; one end of the oil tank device is provided with a main pressure oil tank; the other end of the oil tank device is provided with an auxiliary oil tank; a big piston rod is arranged in the main pressure oil tank; a small piston rod is arranged in the big piston rod; a right pressure head base is arranged on the end part of the big piston rod; a thimble deviceis arranged on the end part of the small piston rod; a thimble device is arranged on the end part of a piston rod of the auxiliary oil tank; and a left pressure head base is sleeved outside the auxiliary oil tank and is fixed on the inner side at the left of the machine frame. When the central hole positioning wheel pair press mounting machine is compared with a dual-head oil tank press mounting machine, a movable beam and an inserting plate as well as a positioning groove (hole) and a locking mechanism are eliminated, so the structure and a control part are simplified; and the auxiliary oil tank at the other end is very small, so the cost is reduced. When the central hole positioning wheel pair press mounting machine is compared with a lengthened rod and pendulum press mounting machine, press mounting is finished through central hole positioning, so a shaft and a shaft end are not damaged, and the press mounting quality and the train safety are improved.

Description

technical field [0001] The invention relates to equipment machinery for railway locomotives, suitable for wheels of locomotives with different gauges such as meter gauge, quasi-gauge, wide gauge, urban rail transit (subway, light rail), passenger cars with 2 to 3 brake discs, ordinary freight cars, etc. , axles, brake discs, reduction boxes or similar parts assembly, pressure inspection or extrusion test and back pressure test. It is especially suitable for fully automatic press-fitting of high-speed train wheel sets. Background technique [0002] Due to the rapid development and widespread use of high-speed trains, the design of wheel sets has been continuously updated, and higher requirements have been placed on their assembly and disassembly, which in turn has led to continuous follow-up and innovation of corresponding equipment machinery. At present, there are two basic types of corresponding press-fitting and unloading machines: one of them is a single-head oil cylinde...

AI Technical Summary

Problems solved by technology

So far, although there have been many patented products of pressing and unloading machines, which meet the market needs after the train speed is increased, they are still not perfect enough and not ideal.
