Abstract
The invention discloses a kind of accurately location bearing shell medial surface processing unit (plant), the cambered surface of the limited block of fixing bearing shell is made up of multiple cylinder that can roll, when bearing shell to be processed is placed in this cambered surface, bearing shell lateral surface contacts with this cambered surface, if the position that bearing shell is placed is not position to be processed (center of gravity is not in minimum point), then can produce downward active force under gravity, and owing to being rolling friction with cylinder, frictional force is very little, then can slide into Working position accurately easily.
Description
Technical field
The present invention relates to bearing shell processing technique field, particularly relate to a kind of accurately location bearing shell medial surface processing unit (plant).
Background technology
Bearing is in mechanical transmission course, play parts that are fixing and reduction load coefficient of friction.Alternatively, be other parts when producing relative motion each other on axle, be used for reducing the fixing parts of coefficient of friction in power transmission process and retainer shaft center.By the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two class.Bearing shell be sliding bearing directly be coupling tactile part, unusual light, the high-abrasive materials such as general bronze, antifriction alloy are made, and shape is the semi-cylindrical of tiles.The effect of bearing shell is the active force that carrying axle journal applies, and keeps oil-film stabilization, makes bearing smooth working and reduces the friction loss of bearing.Bearing shell generally comprises: main bearing shell, is arranged on the main bearing seat of body, and its effect reduces the frictional resistance of axle journal and reduces the wearing and tearing of axle journal; Thrust bearing shell, is arranged on the inner side of main bearing seat, bears the thrust of axial float during the rotation of bent axle, and has anti-attrition effect; Crankshaft bearing liner, is arranged on the analog bracket of bent axle and cylinder body.
During sliding bearing work, between bearing shell and rotating shaft, require the oil film lubricate that one deck is very thin.If insufficient lubrication, just there is directly friction between bearing shell and rotating shaft, friction can produce very high temperature, although bearing shell is because special High-temperature resistant alloy material is made, the high temperature that generation direct friction produces still is enough to be burnt out.In addition, in order to reduce frictional force, needing the radian ensureing bearing shell medial surface, and bearing shell medial surface is polished to smooth enough, to reduce the frictional force between bearing shell and axle as far as possible.
In prior art, bearing shell is processed, after needing to be fixed bearing shell, use cutter to process bearing shell medial surface.Current is arrange to have the spatial accommodation coordinated with bearing shell lateral surface on lathe base to the fixed form of bearing shell, add man-hour, bearing shell is placed in spatial accommodation, edge uses the instruments such as position limiting clamp to be fixed, ensure that bearing shell can not move, re-use the rotation of driven by motor cutter and bearing shell medial surface is processed.But, when prior art places bearing shell, because operate miss may cause the calibration position that accurately cannot be put into spatial accommodation, and due to bearing shell lateral surface and limited block cambered surface friction coefficient comparatively greatly, not easily adjust to calibration position.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of accurately location bearing shell medial surface processing unit (plant), achieving the accurate location that bearing shell medial surface adds man-hour.
The one that the present invention proposes accurately locates bearing shell medial surface processing unit (plant), comprising:
Base;
Limited block, be arranged on described base, described limited block has cambered surface, parallelly in described cambered surface closely arranges the identical cylinder roller bearing of multiple diameter, its axis is consistent with described bearing shell axis direction, and described multiple cylinder roller bearing forms the spatial accommodation coordinated with bearing shell lateral surface;
Support, is arranged on described base;
First guide rail, one end is arranged on the top of described support, and the other end suspends downwards, and second guide rail that can arrange on described support is along sliding with bearing shell line parallel direction;
Rotating shaft, is arranged on described first guide rail, can slide up and down along described first guide rail;
Cutter, is arranged in described rotating shaft, along with the rotation of described rotating shaft is processed bearing shell medial surface.
Preferably, described multiple cylinder roller length is identical.
Preferably, the top of described limited block also has position limiting clamp, after accurate machining position adjusted to by bearing shell, steps up bearing shell edge and is fixed.
In the present invention, the cambered surface of the limited block of fixing bearing shell is made up of multiple cylinder that can roll, when bearing shell to be processed is placed in this cambered surface, bearing shell lateral surface contacts with this cambered surface, if the position that bearing shell is placed is not position to be processed (center of gravity is not in minimum point), then can produce downward active force under gravity, and owing to being rolling friction with cylinder, frictional force is very little, then can slide into Working position accurately easily.
