Slide rail of the present invention arranges wall scroll or many on boring bar body, every bar slide rail is all equipped with a cutter hub seat and boring cutter cutter hub.
The boring cutter cutter hub quantity that boring cutter quantity regulating member of the present invention can realize participating in boring regulates.
The method of special boring bar processing propeller shaft hole of the present invention is:
1, screw is placed in along axis hole vertical direction on the support bracket of adjustment height and position;
2, by regulating support bracket centering propeller position;
3, special boring bar is regulated as requested:
1), by slide rail conicity regulation bolt regulate slide rail tapering, and by slide rail fishbolt, slide rail is fixedly clamped on boring bar body;
2), regulated by the radial extent amount of boring degree of depth regulating member to boring cutter cutter hub;
3), by boring cutter quantity regulating member, the number of cutters participating in boring is regulated;
4, be inserted in propeller shaft hole by the special boring bar regulated, the boring bar locating shaft on special boring bar top is located by jig, and bottom is connected with driver element by flange;
5, by arranging boring bar and whether rotate and whether boring cutter cutter hub sliding along slide rail, the processing of propeller shaft internal surface of hole and oily wire casing can be completed.
Advantage of the present invention is apparent, is mainly manifested in:
1, the boring that propeller shaft hole becomes special boring machine from the turnery processing of lathe is in the past processed, solve large-size propeller diameter of propeller blade, propeller hub height and screw overall weight to the restricted problem of propeller shaft hole machined, achieve the unrestricted processing of marine propeller axis hole;
2, by adjustment boring bar slide rail taper value, the high consistency of propeller shaft hole tapering and power transmission shaft tapering can be guaranteed;
3, by the different cutter hubs that staged on boring bar peripheral helical riser is uniform, the staged Fast Coarse processing of axis hole can be realized, process the relative lathe of identical axis hole and at least improve more than 200% in efficiency;
4, rotated the boring bar rotation changing into and drive weight to be only several tons by the blade driving weight to reach hundred tons in the past, greatly reduce driving energy consumption;
5, by screw own wt, adjustable seats in Bound moisture plane, coordinate the Automatic-clamping slide block on bearing simultaneously, the screw time that is installed only needs 2-4 minute, lay mix up slide rail tapering in advance integrated form boring bar system in axis hole, can realize the totally enclosed type rapid processing of axis hole, ensure that higher machining accuracy by the method for most simple and fast, processing dimension error is no more than 0.02mm;
The present invention has novel structure, processes the advantages such as easy, easy and simple to handle, efficiency is high, precision is accurate, and it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
