Description
Technical field
The present invention relates to field of machining, specifically is a kind of device that is used to regulate the concentricity of hollow axial workpiece endoporus and cylindrical.
Background technology
Hollow axial workpiece will guarantee the axiality of part endoporus and cylindrical in process.Generally speaking, there is offset in hollow shaft processing back inside and outside circle, needs to correct the back and guarantees with one heart.Part one end clamped and adjustment with chuck when prior art was corrected, and the other end holds out against with top, made the endoporus of part and cylindrical concentric after the pad copper sheet is adjusted offset, reface profile on top.This method operating difficulties is had relatively high expectations to operator's technical merit, and can't guarantee higher required precision, and when offset was bigger, operating difficulties can't be realized.
Summary of the invention
Have in the prior art for overcoming that precision is low, operating difficulties, deficiency that operator's technical merit is had relatively high expectations, a kind of positioner that is used to correct hollow shaft inside and outside circle offset of the present invention.
The present invention includes and regulate support, regulate bolt and reducing sleeve; Regulating support is placed on the bed piece through the contiguous block that is positioned at its lower end; And there is trapezoidal guide-track groove the bottom surface of regulating support contiguous block one side; This dovetail groove cooperates with guide rail on being positioned at bed piece; The contiguous block opposite side of regulating support is the plane, directly is placed in the surface of bed piece.To regulate support through connecting rod and lathe contiguous block is fixedly connected with bed piece.Reducing sleeve is installed in the hole of regulating support through bearing.Ring transition puts and is evenly distributed with four installing holes of regulating bolt.
Reducing sleeve is divided into branch single-side stand structure and double bracket structure.The excircle of reducing sleeve is stepped, has formed to be positioned at reducing sleeve one end or middle radially boss.Reducing sleeve cylindrical end Monday of single-side stand structure has the radially boss of protrusion, and the radially boss of protrusion is arranged in the middle of the reducing sleeve excircle of double bracket structure.When reducing sleeve was the single-side stand structure, the mounting hole site of regulating bolt was on the boss of reducing sleeve one end.When reducing sleeve was the double bracket structure, the mounting hole site of regulating bolt was on the boss of the centre of reducing sleeve.Regulating the installing hole of bolt opens on the radially boss of reducing sleeve one end or centre.
Regulate the external diameter of the aperture of support large diameter hole with bearing.Regulate the aperture of the aperture of support one end end plate centre bore, and the end face of regulating support this end is distributed with and is used for screwed hole that the adjusting support is connected with reducing sleeve with the reducing sleeve endoporus.
When adopting the reducing sleeve of double bracket structure, two adjusting supports lay respectively at the radially both sides of boss of reducing sleeve, are installed on the bed piece guide rail.The end plate centre bore of two adjusting support circular shells lays respectively at the both sides of device.The dovetail groove of two adjusting support lower ends is positioned at same one side of device.
The structure that adjusting support of the present invention is concentricity is installed on the bed piece guide rail with bearing, and the bearing pivot is concentric with the machine tool chief axis centre of gyration; Reducing sleeve is sleeve-like, and one section cylindrical cooperates with the bearing inner race aperture, and another section is used to put into the part cylindrical; Part is put in the reducing sleeve; The adjustment screw that is installed on the reducing sleeve is used for the support part cylindrical; Leave big gap between reducing sleeve and part; Regulate the part center through the regulating handle on the reducing sleeve, the part cylindrical is regulated numerical value with the dial gauge monitoring display, thereby reaches the concentric purpose that guarantees hollow axial workpiece endoporus and cylindrical.The present invention is divided into single-side stand structure and double bracket structure, and through test, two kinds of structures all can satisfy the coaxial accuracy requirement, but the single-side stand structure is applicable to the workpiece of length less than 1000mm, and the double bracket structure is applicable to the workpiece of length greater than 1000mm.
The present invention can adjust the offset of part endoporus and cylindrical accurately, easily through regulating handle and dial gauge, guarantees the high-precision concentric requirement of part; Install easy and simple to handlely, the operator is required lower; Can be applicable to all kinds of machine tools and numerical control horizontal machine tool; Can be widely used in all kinds of hollow shafts; Concentricity is regulated and can be realized through turning handle, and is easy to operate, reliable, and working (machining) efficiency is high.
