On the basis of above scheme, it is preferred that the spindle drive motor and the Feed servo system motor are mounted on together
Side.
Further, the plate that furthers directly is additionally provided with more guide rods, the guide rod with the Feed servo system motor
One end is furthered on plate described in being fixed on, and the other end is fastened on the bracket of the Feed servo system motor.
Row on the basis of above scheme, preferably, being also cased with cushion on the guide rod.
Further, the end head of the guide rod is equipped with sensing iron plate, is equipped on motor corresponding close
Switch.
The quantity of the guide rod is two as a preferred technical solution, is symmetrically mounted on the two sides of the sliding sleeve.
As further preferred scheme, the two sides of the sliding sleeve are cased with bearing.
On the basis of above scheme, it is preferred that screw rod protective cover, the screw rod protective cover are installed on the plate that furthers
Inside is hollow structure, and the screw rod can be movable in the screw rod protective cover.
The Feed servo system motor is servo motor as a preferred technical solution,.
The beneficial effect of the utility model compared with the existing technology is: the brill is attacked power head and is stretched using whole sliding sleeve, sliding
Set stretching motion remain with electric machine casing comprehensive engagement so that the steadily of centre of gravity of whole equipment, the good gap of rigidity is small, increases
Stability of the equipment in work, reduces vibration, to improve the machining accuracy of equipment.
Detailed description of the invention
Fig. 1 is the overall structure figure of the utility model；
Fig. 2 is the cross-sectional view of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As depicted in figs. 1 and 2, a kind of telescopic brill of sliding sleeve attacks power head, including power head 1, and power head 1 is connected to main shaft
On 2, one end of main shaft 2 is connected to power head 1, and the other end is connect by synchronous belt 31 with spindle drive motor 32, which drives
Dynamic motor 32 generally uses threephase asynchronous machine, and motor rotation drives synchronous belt 31 to drive the rotation of main shaft 2 to realize drilling
Or the effect of tapping.
It is arranged with sliding sleeve 4 outside main shaft 2, is cased with bearing 21 and 22 at the both ends of main shaft 2；Feeding is installed above sliding sleeve 4
Driving motor 5, the Feed servo system motor 5 and spindle drive motor 32 are mounted on the same side, can protect at work in this way
The center of gravity of card whole equipment will not deviate, and increase stability of the equipment in work, reduce vibration, to improve equipment
Machining accuracy.
The Feed servo system motor 5 uses servo motor in the present embodiment, which is mounted on motor cabinet 51, motor cabinet
51 are wrapped in the surface of sliding sleeve 4, and motor cabinet 51 can be slided with Feed servo system motor 5 on 4 surface of sliding sleeve, in order to realize sliding
Effect, the output shaft of the Feed servo system motor 5 is connected with screw rod 6, nut 61 is cased on screw rod 6, and nut 61, which is fixed on, to further
On plate 7, the plate 7 that furthers is fixed on bracket 8.When Feed servo system motor 5 works, screw rod 6 is driven to rotate, due to being cased on screw rod 6
It is fixed on the nut 61 to further on plate 7, so entire Feed servo system motor 6 will be toward the sliding of plate 7 that furthers, such sliding sleeve 4 will
Exposing slowly, while power head 1 also just extends, and the effect of feeding is realized, when this mode realizes the effect of feeding
Sliding sleeve stretching motion remain with electric machine casing comprehensive engagement so that the steadily of centre of gravity of whole equipment, the good gap of rigidity is small, from
And improve machining accuracy.
In order to guarantee the stability of screw rod 6 at work, furthering screw rod protective cover 61 is installed on 7 plates, screw rod protection
61 inside of cover is hollow structure, and screw rod 6 can be movable in the screw rod protective cover 61.
In order to guarantee that Feed servo system motor 5 in the stability of sliding, is fixed with more guide rods furthering on plate 7, at this
In embodiment, using two guide rods 9 (in figure to depict one, another opposite in guide rod 9), respectively symmetrically install
In the two sides of Feed servo system motor 5,9 one end of guide rod be fixed on it is described further on plate 7, the other end is fastened on the Feed servo system
On the motor cabinet 51 of motor.In this way under the guidance of guide rod 9, Feed servo system motor 5 in the process of moving, would not occur
It is the case where offset, more stable.
In addition, the phenomenon that Feed servo system motor 5 collides in the process of moving in order to prevent, on guide rod 9 also
It is cased with cushion 91, for preventing motor 5 from colliding when sliding near the plate 7 that furthers, further, at the end of guide rod 9
Head is equipped with sensing iron plate 92, is then equipped on the motor cabinet 51 of motor 5 or Feed servo system motor again and incudes iron therewith
Piece 92 is corresponding close to switch (being not drawn into figure), in this way when Feed servo system motor 5 close to further plate 7 when, close to switch (in figure
It is not drawn into) also close to sensing iron plate 92, controller will be sent a signal at this time, Feed servo system motor 5 is allowed to stop working, and prevented
Collision, improves the service life of equipment.
