Description
Technical field
It the utility model is related to a kind of main shaft device of external diameter grinding machine, in particular to a kind of high stable type external diameter grinding machine
Main shaft device.
Background technology
External diameter grinding machine is used in a kind of milling apparatus of grinding miniature workpiece.External diameter grinding machine may be employed to grind work
The inside and outside circle of part, there is the advantages of simple to operate, grinding precision is high.In existing external diameter grinding machine, main shaft is installed installed in main shaft
In seat, both ends are respectively locked main shaft by two jackscrews, and emery wheel is directly installed on main shaft.Lock occurs in the mode of jackscrew locking
The problem of bad main shaft in clamp force square top.Start to carry out main shaft installation and locking using unilateral hood type mounting seat for this many production man,
But rotating speed is higher when being ground to workpiece due to main shaft, vibration is easily produced, causes main shaft and unilateral hood type to be installed
There is connection gap between seat, greatly reduce installation effect, and reduce the service life of device.Therefore, a tool is designed
There is enough stability, and the main shaft device for the high stable type external diameter grinding machine that can effectively increase the service life is that this practicality is new
The research purpose of type.
The content of the invention
For in place of above-mentioned the shortcomings of the prior art, the utility model is to provide a kind of high stable type external diameter grinding
The main shaft device of machine, the main shaft device of the high stable type external diameter grinding machine has enough stability, and service life is grown.
The technical solution of the utility model is：
A kind of main shaft device of high stable type external diameter grinding machine, including the main shaft mounting seat of unilateral hood type, main shaft orientation
Post and main shaft, the main shaft device chamber being provided centrally with for main shaft described in device of the main shaft orientation post, the main shaft pass through
Corresponding rolling bearing tumbler stretches out the main shaft device chamber respectively in the main shaft device intracavitary, the both ends of the main shaft
Positioned at the outside of the main shaft orientation post, the main shaft is by the main shaft orientation post with main shaft mounting seat adapting device in described
In main shaft mounting seat, a circle is provided with the inside of the main shaft mounting seat and buffers locking rubber ring, the buffering locking accordingly
The rubber ring side relative with main shaft mounting seat be arranged to it is plane, buffering locking rubber ring it is relative with the main shaft orientation post
Side is arranged to zigzag, is locked at the hoop mouth of the main shaft mounting seat by bolt.
Device has belt pulley for being connected to respective drive mechanism and for connecting emery wheel respectively at the both ends of the main shaft
Grinding wheel flange.
Grinding wheel flange is locked on main shaft by taper fit.
The advantages of the utility model：
Main shaft orientation post of the present utility model is provided centrally with the main shaft device chamber for device main shaft, and main shaft passes through corresponding
Rolling bearing tumbler matched somebody with somebody in the main shaft device intracavitary, the main shaft by the main shaft orientation post with main shaft mounting seat
Attach together and be placed in the main shaft mounting seat.Locking rubber ring is buffered accordingly by being provided with a circle on the inside of main shaft mounting seat
Buffering effect is effectively increased, there is the probability in gap in the connection being greatly reduced between main shaft and main shaft mounting seat, while by institute
State the buffering locking rubber ring side relative with main shaft mounting seat and be arranged to plane, effectively ensure the stationarity of connection, will delay
The punching locking rubber ring side relative with main shaft orientation post is arranged to zigzag, on the premise of stable connection is ensured, effectively carries
High main shaft mounting seat improves locking installation effect so that the utility model has enough steady to the coupling mechanism force of main shaft orientation post
It is qualitative, and can effectively increase the service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional views in Fig. 1.
Embodiment
For the ease of it will be appreciated by those skilled in the art that existing make embodiment combination accompanying drawing into one to structure of the present utility model
Step is described in detail：
With reference to figure 1-2, a kind of main shaft device of high stable type external diameter grinding machine, include the main shaft mounting seat of unilateral hood type
1st, main shaft orientation post 2 and main shaft 3, the main shaft device being provided centrally with for main shaft described in device 3 of the main shaft orientation post 2
Chamber, the main shaft 3 are distinguished by the corresponding tumbler of rolling bearing 4 in the main shaft device intracavitary, the both ends of the main shaft 3
The outside that the main shaft device chamber is located at the main shaft orientation post 2 is stretched out, the main shaft 3 passes through the main shaft orientation post 2 and master
In in the main shaft mounting seat 1, the inner side of the main shaft mounting seat 1 is provided with a circle and delayed accordingly the adapting device of axle mounting seat 1
Punching locking rubber ring 5, the buffering locking rubber ring 5 side relative with main shaft mounting seat 1 are arranged to plane, buffering locking
The side relative with the main shaft orientation post 2 of rubber ring 5 is arranged to zigzag, passes through spiral shell at the hoop mouth of the main shaft mounting seat 1
Bolt 6 is locked.
Device has belt pulley 7 for being connected to respective drive mechanism and for connecting sand respectively at the both ends of the main shaft 3
The grinding wheel flange 9 of wheel 8.Grinding wheel flange 9 is locked on main shaft 3 by taper fit.
The utility model effectively improves lock of the main shaft mounting seat 1 to main shaft orientation post 2 on the premise of stable connection is ensured
Clamp force, improve locking installation effect so that the utility model has enough stability, and can effectively increase the service life.
The foregoing is only preferred embodiment of the present utility model, it is all done according to present utility model application the scope of the claims it is equal
Deng change and modification, it should all belong to covering scope of the present utility model.
