Description
[technical field]
The present invention relates to machining equipment technical field, in particular to a kind of machine tool chief axis with cooling cycle.
[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 existing main shaft, external cooling tube is generallyd use
Road cools down cutter, also has part machine tool chief axis using built-in cooling pipe, but all there is the phenomenon that coolant liquid splashing,
Cause the utilization rate of coolant liquid low, lathe is difficult to clean, and the cooling effect of main shaft is poor, and it is poor to further result in machining accuracy.
[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 machine tool chief axis with cooling cycle, pass through knot
The Curve guide impeller of structure effectively realizes the cooling of machine tool chief axis using built-in cooling cycle channel, improves machining essence
Degree.
To achieve the above object, technical scheme is as follows:
A kind of machine tool chief axis with cooling cycle, including main shaft body, the top of the main shaft body are provided with rotary joint,
The center of the main shaft body is provided through cooling main road, and a plurality of cooling secondary road, institute are provided in the main shaft body side
The upper end for stating cooling secondary road is provided with cooling liquid outlet, and the rotary joint is connected to the cooling main road, and the cooling secondary road connects
Lead to the cooling main road；The lower end of the cooling main road is provided with tool mounting portion, and the cooling main road is connected to the cutter
Mounting portion.
Further, groove-like is set to the outer surface of the main shaft body to the cooling liquid outlet in a ring.
Further, the upper and lower ends of the cooling liquid outlet are provided with sealing strip, avoid the leakage of coolant liquid.
The cooling main road and the cooling secondary road are set the beneficial effects of the present invention are: passing through, and cold built in formation
But circulation canal effectively realizes the cooling of machine tool chief axis, smooth running；Simultaneously as the cooling main road and the cutter
Mounting portion connection, realizes the cooling of cutter, improves machining accuracy.
[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, main shaft body, 2, rotary joint, 3, cooling main road, 4, cooling secondary road, 5, cooling liquid outlet, 6, cutter
Mounting portion, 7, sealing strip.
[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 machine tool chief axis with cooling cycle, including main shaft body 1, the top of the main shaft body 1
It is provided with rotary joint 2, the center of the main shaft body 1 is provided through cooling main road 3, sets in 1 side of main shaft body
It is equipped with a plurality of cooling secondary road 4, the upper end on the cooling secondary road 4 is provided with cooling liquid outlet 5, and the rotary joint 2 is connected to described
Cooling main road 3, the cooling secondary road 4 are connected to the cooling main road 3；The lower end of the cooling main road 3 is provided with tool mounting portion
6, and the cooling main road 3 is connected to the tool mounting portion 6.
Groove-like is set to the outer surface of the main shaft body 1 to the cooling liquid outlet 5 in a ring.
The upper and lower ends of the cooling liquid outlet 5 are provided with sealing strip 7, avoid the leakage of coolant liquid.
The present invention forms built-in cooling cycle channel by the way that the cooling main road 3 and the cooling secondary road 4 is arranged,
Effectively realize the cooling of machine tool chief axis, smooth running；Simultaneously as the cooling main road 3 connects with the tool mounting portion 6
It is logical, the cooling of cutter is realized, machining accuracy is improved.
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.
