Abstract
The utility model discloses a kind of fine motion to hold out against tailstock structure,It includes tailstock casing,Tailstock spindle,Double-row self-aligning ball bearing,Deep groove ball bearing,Fore bearing locking nut,Bearing lock nut afterwards,Piston rod,Sealing ring,Guide and limit pin and clamping cone,Wherein described tailstock spindle passes through the tailstock casing,The double-row self-aligning ball bearing is arranged on the preceding axle journal of the tailstock spindle and locked with the fore bearing locking nut,The deep groove ball bearing is arranged in the rear shaft neck of the tailstock spindle and locked with the rear bearing lock nut,The sealing ring is arranged on the piston rod,The piston rod is arranged in the tailstock spindle,The guide and limit pin is fixed with the tailstock spindle screw,The piston rod being capable of the micro slip in the tailstock spindle,The clamping cone is connected through a screw thread on the piston rod.Fine motion of the present utility model holds out against the error in length that tailstock structure compensates part when multistation clamps by hydraulic drive piston bar, and clamping accuracy is high, it is stable and reliable in work the advantages that.
Description
Technical field
Metal-working plant technical field is the utility model is related to, is particularly adapted to multistation finding center hole machined to set
It is standby, more particularly to a kind of fine motion holds out against tailstock structure.
Background technology
Multistation finding center hole machined is held out against using telescopic oil cylinder at present, complicated, step up to act it is inconsistent, it is auxiliary
The time is helped to grow.
Based on above technological deficiency, in order to overcome the multistation finding holding action time to grow, the problem of inconsistent is acted,
The utility model provides a kind of easy to operate fine motion rational in infrastructure and holds out against tailstock structure.
Utility model content
The purpose of this utility model is to overcome prior art insufficient, there is provided one kind can micro motion compensation using piston rod
Part error, clamp rapidly, the high fine motion of clamp precision holds out against tailstock structure.
The technical solution of the utility model is：A kind of fine motion holds out against tailstock structure, it include tailstock casing, tailstock spindle,
Double-row self-aligning ball bearing, deep groove ball bearing, fore bearing locking nut, rear bearing lock nut, piston rod, sealing ring, guiding limit
Position pin and clamping cone, wherein the tailstock spindle passes through the tailstock casing, the double-row self-aligning ball bearing is arranged on described
Locked on the preceding axle journal of tailstock spindle and with the fore bearing locking nut, the deep groove ball bearing is arranged on the tailstock spindle
Rear shaft neck on and locked with bearing lock nut after described, the sealing ring is arranged on the piston rod, the piston rod
In the tailstock spindle, the guide and limit pin is fixed with the tailstock spindle screw, and the piston rod can be in institute
Micro slip in tailstock spindle is stated, the clamping cone is connected through a screw thread on the piston rod
Further, in addition to belt wheel and swivel joint, the belt wheel are fixedly mounted on the tailstock master with nut check
The tail end of axle, the swivel joint are threadedly coupled with tailstock spindle and are arranged on its end
Further, in addition to preceding sealing flange, the front end that the preceding sealing flange is arranged on the tailstock casing are used in combination
Screw is fixed.
In summary, the beneficial effects of the utility model are：Fine motion of the present utility model holds out against tailstock structure and passes through hydraulic pressure
The error in length of part when driving piston rod compensation multistation clamping, clamping accuracy is high, it is stable and reliable in work the advantages that..
The present invention is described in more detail below by embodiment.
Brief description of the drawings
Fig. 1 is the structure sectional view that fine motion of the present utility model holds out against tailstock structure.
Embodiment
1 the utility model is further described with embodiment below in conjunction with the accompanying drawings.But protection model of the present utility model
Enclose and be not limited to this.
Fig. 1 shows that fine motion of the present utility model holds out against tailstock structure, and the mechanism is used in metal-working plant, particularly
It is adapted to multistation finding device for processing center hole, it includes tailstock casing 1, tailstock spindle 2, double-row self-aligning ball bearing 3, zanjon
Ball bearing 4, fore bearing locking nut 5, rear bearing lock nut 6, belt wheel 7, belt wheel locking nut 8, swivel joint 9, piston rod
10th, sealing ring 11, guide and limit pin 12, clamping cone 13, preceding sealing flange 14, wherein double-row self-aligning ball bearing 3 are arranged on tailstock
Locked on the preceding axle journal of main shaft 2 and with fore bearing locking nut 5, deep groove ball bearing 4 is arranged in the rear shaft neck of tailstock spindle 2 simultaneously
Locked with rear bearing lock nut 6, and in tailstock casing 1, belt wheel 7 is arranged on tailstock spindle tail end, and uses belt wheel
Locking nut 8 is locked, and swivel joint 9 is threadedly coupled with tailstock spindle 2 is arranged on end, and preceding sealing flange 14 is arranged on tail
The front end of frame casing is simultaneously screwed.Sealing ring 11 is arranged on piston rod 10, and piston rod 10 is arranged in tailstock spindle.Lead
Fixed to spacer pin 12 and tailstock spindle screw, piston rod 10 can the micro slip in tailstock spindle, the screw of clamping cone 13 installation
On the piston rod.
The utility model compensates the error in length of part when multistation clamps, clamping accuracy by hydraulic drive piston bar 10
Height, it is stable and reliable in work the advantages that.
Fine motion of the present utility model holds out against the structure that tailstock structure is not limited in above-described embodiment, can carry out a variety of changes
Type, in a word, both fallen within all improvement not departed from the utility model scope in the scope of the utility model.
