Description
[technical field]
The present invention relates to machining equipment technical field, in particular to a kind of main spindle box of numerical control of oil bath structure.
[background technique]
In machining equipment, the main shaft component one of most basic as lathe, one end is connected with process tool, carries out machine
The processing of tool components, the other end are connected with motor, its rotation or rise and fall are driven by motor.When being machined,
Between cutter and process component, heat can be generated between main shaft and cutter, heat excludes to will lead to tool wear not in time
Accelerate, or even damage, fracture, main shaft temperature distortion influence machining accuracy.In spindle box, bearing is to rotate to transport as main shaft
Dynamic foundation stone determines the stability of spindle operation and the precision of machining, and whether bearing heat dissipation performance is well lathe
The crucial examination factor that spindle box designs and produces.
[summary of the invention]
In view of this, in order to overcome the deficiencies of the prior art, the present invention provides a kind of main spindle box of numerical control of oil bath structure, pass through
The Curve guide impeller of structure is ensured that the bearing in spindle box guarantees certain running temperature by the way of oil immersion, avoids temperature mistake
There is the phenomenon that clamping stagnation in height, improves the stability of spindle operation and the precision of machining.
To achieve the above object, technical scheme is as follows:
A kind of main spindle box of numerical control of oil bath structure, including Machine tool box body and main shaft body, the outer cover of the main shaft body
There are four rolling bearing, being horizontally disposed in the Machine tool box body has the first oil bath channel, the second oil bath channel, third oil bath channel
And the 4th oil bath channel of state in a vertical shape setting, first oil bath channel, the second oil bath channel, third oil bath channel with
And the 4th oil bath channel be laid out in king's font, and the first oil bath channel, the second oil bath channel and third oil bath channel are respectively set
At contact surface between the rolling bearing described in any two.
First oil bath channel, the second oil bath channel, third oil bath channel and the 4th oil bath channel are formed in one
The cooling grease chamber of circulation realizes effective cooling of the rolling bearing, avoids the rolling bearing temperature excessively high and clamping stagnation occurs
The phenomenon that, improve the stability of spindle operation and the precision of machining.
Further, the lower end surface of the Machine tool box body is provided with drain oil, and screwing in the drain oil has plug, is convenient for
It drains the oil and changes oil.
Further, it is provided with cooling passage in the main shaft body, reinforces the cooling to the rolling bearing inner ring.
The beneficial effects of the present invention are: realizing effective cooling of the rolling bearing, the rolling bearing temperature mistake is avoided
It is high and the phenomenon that clamping stagnation occur, improve the stability of spindle operation and the precision of machining.
[Detailed description of the invention]
It in order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below will be to embodiment or existing skill
Attached drawing needed in art description is briefly described, it should be apparent that, the accompanying drawings in the following description is only the present invention
Some embodiments for those of ordinary skill in the art without creative efforts, can also basis
These attached drawings obtain other attached drawings.
Fig. 1 is the structural diagram of the present invention.
In figure, 1, Machine tool box body, 2, main shaft body, 3, rolling bearing, the 4, first oil bath channel, the 5, second oil bath channel,
6, third oil bath channel, the 7, the 4th oil bath channel, 8, drain oil, 9, plug, 10, cooling passage.
[specific embodiment]
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clearly and completely
Description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Referring to Fig.1, a kind of main spindle box of numerical control of oil bath structure, including Machine tool box body 1 and main shaft body 2, the master
The outer cover of shaft body 2 is horizontally disposed with there are four rolling bearing 3, in the Machine tool box body 1 first the 4, second oil of oil bath channel
Bathe the 4th oil bath channel 7 in channel 5, third oil bath channel 6 and state in a vertical shape setting, first oil bath channel 4, second
Oil bath channel 5, third oil bath channel 6 and the 4th oil bath channel 7 are laid out in king's font, and the first oil bath channel 4, the second oil bath
Channel 5 and third oil bath channel 6 are separately positioned at the contact surface between rolling bearing 3 described in any two.
First oil bath channel 4, the second oil bath channel 5, third oil bath channel 6 and the 4th oil bath channel 7 form one
The cooling grease chamber of a interior circulation realizes effective cooling of the rolling bearing 3, avoids 3 temperature of rolling bearing excessively high and goes out
The phenomenon that existing clamping stagnation, improve the stability of spindle operation and the precision of machining.
The lower end surface of the Machine tool box body 1 is provided with drain oil 8, and screwing in the drain oil 8 has plug 9, convenient for draining the oil
With change oil.
It is provided with cooling passage 10 in the main shaft body 1, reinforces the cooling to 3 inner ring of rolling bearing.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
