Abstract
The invention discloses a machining method for the eccentric bushing of the sliding bearing and relates to the field of machining. The machining method comprises the steps of: preparing the whole rounded blank, and roughly turning the outer circle and the inner hole at one time to ensure the concentricity and surface roughness of the inner and outer circles, reserving 13-15mm of technical chuck in the axial size of the whole rounded blank, and dehydrogenizing for the chuck. As in the steel smelting process residual hydrogen ions exist inevitably, hydrogen ions continue to break down into hydrogen from the steel over time, a part of precipitated hydrogen is accumulated in the combination position of the bushing steel and alloy to cause swelling. In order to prevent hydrogen precipitation from the steel and ensure the combination quality of the steel and alloy, the machining method has the advantages of simple operation and convenient processing, can guarantee the machining quality and machining precision of the workpiece and can improve the production efficiency and reduce manufacturing cost.
Description
Technical field
The present invention relates to field of machining, the processing method being specifically related to sliding bearing bias tile fragment.
Background technology
It is high that many tile fragments tilting bush sliding bearing has stability, and friction loss is less, and temperature rise is relatively low and bearing capacity is moderate
Etc. feature, it is widely used in recent years in high-speed turbine machinery drive mechanism.Eccentric tile fragment is the vital part of this class bearing, its
Gradient can adjust automatically with axle journal position, keeps the appropriate gap between axle journal and bearing shell, with adapt to different load, rotating speed and
The concrete conditions such as the elastic deformation deflection of axle.Eccentric tile fragment uses endoporus and excircle eccentricity structure, and requirement on machining accuracy is high, tradition
Technique uses Boring machine processing, the technique of first turning reprocessing eccentric inner hole to there are problems, therefore, how to process eccentric watt
Block becomes the problem that technologists needs to solve.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of simple to operate, convenient processing, and can guarantee that workpiece add working medium
Amount and machining accuracy, improve production efficiency, the processing method reducing the sliding bearing bias tile fragment of production cost.
The processing method of sliding bearing bias tile fragment of the present invention, comprises the following steps:
The first step, prepares full circle blank material, and clamped one time completes rough turn cylindrical and endoporus, to ensure inside and outside round concentricity and table
Surface roughness, the axial dimension at full circle material stays the locating pad of 13-15mm, chuck jaws clamping workpiece when turning；
Second step, rough turn cylindrical, endoporus and both ends of the surface, retain locating pad；
3rd step, Dehydroepiandrosterone derivative, owing to the smelting process of steel being inevitably present residual hydrogen ion, pushing away over time
Moving, hydrion constantly resolves into hydrogen and separates out from steel, and the part separating out hydrogen is assembled in the knot of tile fragment steel body Yu alloy
Close position and cause bulge phenomenon, for the precipitation of hydrogen in prevention steel body, it is ensured that steel body and the bond quality of alloy, in cast alloys
Front reply steel body carries out a Dehydroepiandrosterone derivative；
4th step, half finish turning, it is desirable to alloy faying face is not more than 60r/min without greasy dirt, non-oxidation, low speed machining in lathe, workpiece rotational frequency,
The amount of feeding is 0.4mm/r, and back engagement of the cutting edge is less than 0.5mm cutter for same, measurer, accessory oil removing, adds and does not allow man-hour to use cooling
Liquid, the alloy faying face Do not touch after processing or other contaminations；
5th step, integral metal；
6th step, half finish turning；
7th step, grinds both ends of the surface；
8th step, ultrasonic examination inspection alloy faying face quality；
9th step, bores fabrication hole, for workpiece clamping in frock；
Tenth step, cuts each tile fragment；
11st step, kerosene leaking test；
12nd step, uses fixture vehicle eccentric excircle, stays mill amount；
13rd step, mill eccentric excircle is to technological requirement.Need before grinding to repair center lapping, to improve positioning precision, thus improve
The positional precision of surface to be machined；
14th step, finish turning endoporus；
15th step, cleans, kerosene leaking test.
The present invention is simple to operate, convenient processing, and can guarantee that crudy and the machining accuracy of workpiece, improves and produces effect
Rate, reduces production cost.
