Description

A kind of self-stabilising bearing inner surface processing machine
Technical field
The present invention relates to bearing machining equipment technical field, specifically a kind of self-stabilising bearing inner surface processing machine.
Background technology
Bearing is a kind of important spare part in contemporary mechanical equipment, its major function is the mechanical rotary body of support, is reduced Friction coefficient in its motion process, and ensure its rotating accuracy;Rolling bearing is generally by outer ring, inner ring, rolling element and holding Four part of frame forms, and is strictly speaking made of outer ring, inner ring, rolling element, retainer, sealing, six big part of lubricating oil.It is simple next It says, may be defined as rolling bearing as long as having outer ring, inner ring, rolling element.By the shape of rolling element, rolling bearing is divided into ball axis It holds and roller bearing two major classes.
The main process of bearing is exactly to be processed to the surface of bearing inner race and bearing outer ring, usually existing to add Work mode is all by made of lathe process, but this processing method has the following defects:1, bearing machining inner ring, outer ring Usually in forge plant, and lathe due to weight and is inconvenient to move usually in processing workshop, this just to need operator The bearing inner race and bearing outer ring processed takes processing workshop, complicated for operation, needs a large amount of manpower, and both causing cannot one The main reason for bodyization is processed is that existing process equipment is immovable, can have shake in moving process to influence processing essence Degree, while the movable fixed performance of existing process equipment is poor, when needs cannot be strong movable solid when specific position is processed It is scheduled on operation ground, reduces the scope of application and greatly reduce working efficiency;2, the inner surface of existing bearing race processes work Sequence and generated by lathe process, it is complicated for operation since lathe is bigger, to considerably increase bearing race surface plus Between working hour, process velocity is slow, and can only process a kind of bearing race of diameter after lathe setting program every time, and the scope of application is small, Greatly reduce working efficiency.
Invention content
To solve the above-mentioned problems, it the present invention provides a kind of self-stabilising bearing inner surface processing machine, can solve existing Equipment operation existing for bearing race processing method is complicated, equipment mobility energy is poor, low in the presence of shake, machining accuracy in moving process Under, device activity fixed performance it is poor, cannot specific position activity fix interim processing, long processing time, process velocity it is slow, one Secondary program can only process the problems such as a kind of diameter part, the scope of application are small and working efficiency is low, may be implemented bearing from steady The automatic machining function of mobile processing and inner surface, and easy, equipment mobility can be in good, moving process not with equipment operation There are any shake, high precision machining, device activity fixed performance is good, can fix interim processing, processing in specific position activity The advantages that time is short, process velocity is fast, the scope of application is big and work efficiency is high.
To achieve the goals above, the present invention is realized using following technical scheme:A kind of self-stabilising bearing inner surface adds Work machine, including from steady mobile foundation, may be implemented to tremble there is no any from steady locomotive function, moving process from steady mobile foundation Dynamic, equipment mobility can be good, and can be fixed temporarily processing in specific position, and movable fixed performance is good, described from steady mobile foundation Upper surface inner surface processing apparatus is installed, the full-automatic processing work(of bearing inner surface may be implemented in inner surface processing apparatus Can, high precision machining, process time is short, and process velocity is fast, and the scope of application is big, and work efficiency is high.
