Problems solved by technology

Such a long boring bar will inevitably produce deflection when both ends are fixed, so the original set of processing equipment is equipped with two intermediate bearings. By adjusting these two intermediate bearings to eliminate the deflection of the boring bar, it still cannot achieve satisfactory processing Requirements, mainly because the coaxiality after boring does not meet the requirements
After analysis, it is found that after the boring bar is installed, the deflection direction of the boring bar is not unidirectional, mainly because in addition to supporting bearing seats at both ends of the boring bar, it is also equipped with feed gear boxes, reductio

Abstract

The invention provides an adjustable middle support device for machining an overlength shaft. The adjustable middle support device comprises a transition sleeve and a support frame, wherein the transition sleeve is radially provided with a transition sleeve adjusting device capable of adjusting a distance between the transition sleeve and a boring rod, the support frame is a hollow circular sleeve and is sleeved on the transition sleeve, two end parts of the support frame are in airtight connection with the transition sleeve, the support frame is radially and symmetrically provided with a support frame adjusting device I capable of adjusting the distance between the support frame and the transition sleeve and a support frame adjusting device II capable of adjusting the supporting frame and a hole wall inside a stern shaft tube, a cavity of the support frame is internally provided with a rubber hose, one end of the rubber hose is in contact with the excircle of the transition sleeve, the other end of the rubber hose is connected with an outlet end of an oil filling nozzle which is fixedly arranged inside the cavity of the support frame, and the top end of the oil filling nozzle extends out of the support frame. The adjustable middle support device disclosed by the invention can be used for not only supporting the long boring rod but also guaranteeing the coaxiality in boring a long shaft hole, and has a higher practical value.

Description

technical field [0001] The invention belongs to the technical field of machining, and in particular relates to an adjustable intermediate support device for ultra-long axis machining. Background technique [0002] The length of the stern tube of a 76,000-ton bulk carrier is more than 3 meters, and the inner hole needs to be bored. The accuracy of the inner hole of the stern tube is related to the installation of the propeller shaft, so it is very important. The roundness, cylindricity and coaxiality of the bored hole must meet the relevant process requirements. Existing Korean long-axis machining equipment, the length of the boring bar has reached more than 8 meters, while the diameter of the boring bar is only 0.22 meters. Such a long boring bar will inevitably produce deflection when both ends are fixed, so the original set of processing equipment is equipped with two intermediate bearings. By adjusting these two intermediate bearings to eliminate the deflection of the b...
