Description
Technical field
The utility model relates to the tailstock tool device, particularly a kind of tailstock device that adopts compound driving.
Background technology
In the construction machinery industry, processing oil cylinder cylinder parts special purpose machine tool-scrape roller is quoted gang tool and is finished scraping and tumbling to longer cylinder body.The tailstock parts need be finished the location to pipe fitting in process.
Tradition tailstock structure is to rotate by handwheel to drive trapezoidal screw drive sleeve generation rectilinear motion, stretching out of sleeve also can adopt hydraulic mechanism to realize, thereby sleeve drives top location and the support that is close to the workpiece realization to workpiece, this kind tailstock structure relative complex, the workpiece type also is restricted.
Summary of the invention
The purpose of this utility model is to design a kind of tailstock device that adopts compound driving, adopts the combination flooding flowing mode of trapezoidal screw, trapezoidal nut transmission and oil pressure actuated, realizes the driving of tailstock and the location of workpiece.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of tailstock device that adopts compound driving comprises base; Tailstock body is fixed on the base; Locating flange is installed on tailstock body one side; It is characterized in that, also comprise, oil cylinder, it mainly is made up of cylinder body, piston, two oil cylinder flanges, two oil connections and seal; Described cylinder body is connected in center, base lower end; Described piston is arranged in the cylinder body; Two oil connections are arranged at the oil cylinder end face of flange that is positioned at the cylinder body both sides respectively, and are communicated with inner chamber of cylinder block; Two trapezoidal nuts are arranged at the two ends of piston respectively, and fix by screw; Trapezoidal screw is arranged in two trapezoidal nuts, and trapezoidal screw one end connects one can drive the driving mechanism that trapezoidal screw rotates; One guarantees that trapezoidal nut and piston can not produce the anti-rotation device that rotatablely moves, and are arranged at the trapezoidal nut of trapezoidal screw one end.
Further, the driving mechanism of described trapezoidal screw one end is motor or hydraulic motor.
Anti-rotation device described in the utility model comprises a limiting plate and a spacer pin; Described limiting plate is connected and fixed on the outer face of trapezoidal nut, and the outer rim of limiting plate is offered a limited impression, and spacer pin is provided with on the base, and the outer rim limited impression card of limiting plate is established spacer pin.
Advantage of the present utility model is:
The utility model adopts the combined feed mechanism of trapezoidal screw pair of nut transmission and oil pressure actuated, makes top tight workpiece steadily reliable, also can adjust pressure according to different workpieces and machining status simultaneously.The utility model cylinder body separates with base, the convenient installation and assembling; Adopt the double trapezoid nut structure simultaneously, adjust and to eliminate backlass after suitable, guarantee robust motion.
The utility model especially can extensively apply in the large diameter pipe fitting processing.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, the tailstock device of the compound driving of employing of the present utility model comprises, base 1; Tailstock body 2 is fixed on the base 1; Locating flange 3 is installed on tailstock body 2 one sides; Also comprise:
Two trapezoidal nuts 5,5 ' are arranged at the two ends that piston 42 overlaps respectively, and fix by screw; Trapezoidal screw 6 is arranged in two trapezoidal nuts 5,5 ', and trapezoidal screw 6 one ends connect one can drive the driving mechanism 7 that trapezoidal screw 6 rotates; In the present embodiment, driving mechanism is a motor.
One guarantees that trapezoidal nut 5 and piston 42 can not produce the anti-rotation device 8 that rotatablely moves, and are arranged at the end face of the trapezoidal nut 5 of trapezoidal screw 6 one ends.
During work, pressure oil enters cylinder body 41 from oil connection 46, promotes the tailstock parts and moves backward, makes the right side of oil cylinder flange 43 be close to piston 42 left shoulder faces, and at this moment, oil hydraulic system must pressurize.At this moment, driving mechanism 7 drives trapezoidal screw 6 rotations, drive trapezoidal nut 5,5 ', because trapezoidal nut and piston 42 link together, simultaneously guarantee by anti-rotation device 8 that trapezoidal nuts and piston can not produce and rotatablely move that entire mechanism is carried out straight-line feed and moved under trapezoidal screw 6 and trapezoidal nut 5,5 ' effect, when moving to apart from workpiece 9 end faces one segment distance (in piston 42 half stroke); Trapezoidal screw 6 stop motions, piston 42 1 ends are by oil connection 45 oilings pressurization, one end is by oil connection 46 decompression of draining the oil, this moment, piston 42 was static relatively, thereby oil pressure actuated base 1 drives tailstock body 2 to workpiece 9 motions, finally be close to workpiece 9 end faces, realize workpiece 9 location by locating flange 3.
