Below example is as a example by being arranged in lathe.
Integrated machine tool headstock as depicted in figs. 1 and 2, including casing, this casing is arranged on lathe
In headstock, it is made up of steel alloy and even surface roughness.Casing is successively by the front case lid being positioned at leading portion
(1), it is positioned at the case body (2) in stage casing and is positioned at back box lid (3) composition of rear, case body (2)
Front end face and rear end face are fitted with front case lid (1) and back box lid (3) respectively, the corresponding binding face of three
It is shiny surface, and case body (2) is respectively equipped with what screw overlapped with front case lid (1), back box lid (3)
Screwed hole, by installing corresponding screw rod, make the front-end and back-end of case body (2) respectively with front case lid (1),
Back box lid (3) is fixing to be connected, and makes laminating closely have good sealing.The most front case lid (1),
Case body (2) and the bottom face of back box lid (3), be all symmetrically distributed with installation screw, and casing is by installing
Respective threaded rod makes it be firmly mounted in the headstock of lathe.
Headstock is provided with the main shaft (4) being arranged in casing, this main shaft (4) case before the two ends of casing are
Highlight outside the two ends of lid (1) and back box lid (3), main shaft (4) is provided with main shaft (4) end face is
The place height casing and axial one of the flange hole of concentrically ringed axis hole (5), this axis hole (5) and lathe
Cause, when headstock is arranged on lathe, need the workpiece of Vehicle Processing to be passed to flange hole laggard by this axis hole (5)
Enter in the processing district of lathe.
In stage casing in casing, i.e. case body (2), motor (6), the installation axle of this motor (6) are installed
Axial consistent to above-mentioned main shaft (4).This motor (6) is servomotor, makes motor under each rotating speed
All can stably linear convergent rate, uncontrolled rotation phenomenon can't occur, including stator (7), rotatable
Be arranged on the rotor (8) of stator (7) center and be arranged in the axis hole (5) at rotor (8) center
And corresponding winding etc., above-mentioned main shaft (4), through this axis hole (5) connected, makes main shaft (4)
Rotate with the operating of motor (6).Existing lathe, particularly numerically controlled lathe, be equipped with data transmission
End, so, in the casing of the present embodiment headstock, it is provided with for controlling and regulating above-mentioned motor (6) fortune
The acquisition controller (9) turned, and it is provided with corresponding data acquisition hole (10) in the rear end face of casing, with
The data transmission terminal of place lathe connects, for gathering, transmit the instruction of place lathe, thus control and
The operating of regulation motor (6).
In casing, main shaft (4) is respectively arranged at two ends with fore bearing (11) and rear bearing in motor (6)
(13), and the two is provided with corresponding front-end bearing pedestal (12) and rear bearing block (14), at bed
During motor (6) rotates in head case, guide and the rotation of supports main shaft (4), make motor (6)
Main shaft (4) is driven to rotate smoothly.In casing, be additionally provided with on main shaft (4) by front locking nut (15),
The self-locking connector that rear locking nut A (16) and rear locking nut B (17) form.Wherein, front lock
Jack panel (15) is positioned at the inner side of above-mentioned fore bearing (11), rear locking nut A (16) be positioned at above-mentioned after
The outside of bearing (13), rear locking nut B (17) is positioned at the rearward end of main shaft (4), pacifies in reality
When using after dress, workpiece enters car through main shaft (4) axis hole (5) of the headstock of the present embodiment, one end
After the machining area of bed, by this self-locking connector, workpiece will be locked.
Formation one it is located in headstock in motor (6), so when motor (6) operates, how to electricity
Machine (6) carries out good heat radiation, makes motor (6) drive main shaft (4) to turn the most at a high speed
Dynamic, by particularly significant.So, as shown in Figures 2 and 3, stator (7) outer wall of motor (6) is solid
Surely the spiral heat dissipation sleeve (18) that surface is continuous print screw socket shape, this spiral heat dissipation sleeve (18) it are coupled with
Being made up of aluminum alloy material, it is that gap is installed with described casing, and gap width is 1-5mm.The left case of casing
Wall, in the initial screw socket front of the upper left side of spiral heat dissipation sleeve (18), has feed liquor through hole (20),
The right tank wall of casing simultaneously, in the screw socket front, end of the lower right side of spiral heat dissipation sleeve (18), has
Go out fluid through-hole (21), feed liquor through hole (20) and the Kong Zhu going out fluid through-hole (21), all with described spiral
Longitudinal axial plane of heat radiation sleeve (18) is vertical, and the two ends of spiral heat dissipation sleeve (18) are also associated with close
Seal (19), it is to avoid coolant is penetrated in other regions in casing.Coolant passes through feed liquor through hole (20)
Flow in the initial screw socket of spiral heat dissipation sleeve (18) exactly, with hand of spiral swirling flow, cooling
Liquid finally circles round to end screw socket and enter precisely intos out fluid through-hole (21) and flow out afterwards, circulates according to this.Cold
But liquid is through the circulation of said process, can be existed by the heat that each position in motor (6) operation process produces
Effectively absorb during coolant convolution and finally flow out, the headstock making the present embodiment is had very
Excellent radiating effect, makes the motor (6) in headstock can turning at 2000r/min-4000r/min
High-speed rotation constantly under speed.
The above only have expressed preferred implementation of the present utility model, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, for
For those of ordinary skill in the art, without departing from the concept of the premise utility, it is also possible to do
Going out some deformation, improve and substitute, these broadly fall into protection domain of the present utility model.Therefore, this reality
Should be as the criterion with claims with the protection domain of new patent.
