Description of drawings
Fig. 1 cuts open structural representation for the master according to a kind of multifunctional gun drill head case of the present utility model.
Fig. 2 is the right TV structure schematic diagram corresponding to Fig. 1.
Among the figure: 1. supporting plate, 2. slide plate, 3. main shaft, 4. chuck, 5. workpiece, 6. primary shaft belt pulley, 7. belt, 8. electrical machine belt pulley, 9. motor cabinet, 10. servo deceleration machine, 11. servomotors, 12. handwheels, 13. leading screw, 14. grating scales, 15. digital display meters, 16. nuts, 17. headstock housings.
The specific embodiment
With reference to a kind of multifunctional gun drill head case shown in explanation accompanying drawing 1 and the accompanying drawing 2, comprise headstock housing 17, such as Fig. 1 middle part, be assemblied in the main shaft 3 on this headstock housing, be installed on the headstock housing by bearing, each pair of bearings of front and back, the carrying of no one-tenth combined load, the then motor of this main shaft of configuration driven.So according to preferred embodiment, described headstock housing has an one-movement-freedom-degree in the direction that horizontal plane is orthogonal to main-shaft axis, this one-movement-freedom-degree is adjusted by the screw screw mechanism, and displacement detector is set at the screw screw mechanism, and the digital display device of this displacement detector output connection.Thereby headstock housing 17 is had can controlled structure be configured, and then adjusts by guiding mechanism, simultaneously, for satisfying the requirement of accurate adjustment, cooperates displacement detecting, by digital display device current location is accurately controlled.
Screw screw mechanism mechanism is one of mechanism that ratio of precision is higher in the straight line driving mechanism, can manually control also and can by such as servo or stepping control, use more extensive in machine tool field.
In the structure of moving sets, using more in machine tool field is guide rail, during using, other adopt such as the moving sets based on shaft hole matching, in structure shown in Figure 1, described one-movement-freedom-degree is configured to a supporting plate 1 and forms the slide plate 2 of guideway by guide rails assembling on this supporting plate, and the guideway precision is high, and lubricated environment is relatively good, such as the T oil groove of dovetail groove below among Fig. 1, convenient structure lubrication system.
Its middle slide plate 2 is as the carrier of described headstock housing and the parts that connect as described screw screw mechanism output, shown in Fig. 1 middle part.
Preferably, described guide rail is the dovetail groove guide rail, and structure is relatively simple, and lubricated environment might as well.
About described displacement detector, can adopt such as rotary encoder rotary-type grating sensor in other words, be directly connected on the leading screw 13, be used for rotation is converted to the detection that rectilinear motion carries out displacement.
In further embodiments, nut 16 when the device that can directly adopt rectilinear motion to detect, as be parallel to leading screw in the screw screw mechanism and the grating scale 14 that arranges, object that he detects, slide plate 2 bottoms as described in nut 16 is connected to shown in Fig. 1 middle lower portion, its displacement can directly be monitored.
And described digital display device is digital display meter 15, and operating personnel can directly read the displacement of control object.
Because the adjustment of headstock housing 17 is not very frequent relatively, therefore, the leading screw 13 of described screw screw mechanism is connected with handwheel 12, manually adjusts simpler direct comparatively speaking.Simultaneously, if adopt as servo or stepping control, not only cost is high, and the trouble point also can increase.
Preferably, described motor is the servomotor 11 with servo index dial, and it connects described main shaft 3 by transmission mechanism.Thereby, when needs bore eccentric orfice or index hole, by the matching shift of headstock housing 17, then undertaken automatically by SERVO CONTROL and calibration accurately, save the clamping time, improve working (machining) efficiency.
Simultaneously, boring cylindrical work, and when having coaxial aperture, eccentric orfice, index hole on the workpiece, adopting calibration control and the transverse shifting of headstock to control, can position fast and accurately.
In structure shown in Figure 1, chuck 4 is driven by servomotor 11, workpiece 5 rotations, and dynamic stiffness is high, guarantees the precision of processing.
Described transmission mechanism comprises servo deceleration machine 10 and the tape handler that is connected this servo deceleration machine and described main shaft, with the application of coupling low-speed big.The low speed here is a relative concept with high pulling torque, those skilled in the art will readily understand, is that Speed Reduction is, output torque can increase.
