Description

Adjustable self-centering bracket
Technical field
The present invention relates to a kind of adjustable self-centering carrier structure, belong to mechanical driving device, be mainly used in supporting and the adjustment of the medium and heavy workpiece of machining.
Background technology
When machine tooling heavy-type shaft-series workpieces, usually adopt the supporting of manual center frame, or adopt self-centering hydraulic pressure center frame supporting, but when workpiece is relatively heavier, the carrying of common manual centre frame is inadequate, and hydraulic center frame is generally revolution enclosed construction, and workpiece loading and unloading is inconvenient.
Summary of the invention
In order to better realize the medium and heavy shaft-like workpiece carrying of machine tooling, the invention provides a kind of adjustable self-centering bracket, it is rational in infrastructure, it is easy to adjust to handle, the adjustable structure of opening, by the compound action of symmetrical two groups of supporting-point movements, realize regulating the supporting of heavy-type shaft-series workpieces, the work-handling of supporting is efficient and convenient.
Technical scheme of the present invention is: for the adjustable self-centering bracket of machine tooling medium and heavy shaft-like workpiece carrying, comprise block bearing, axle, support, slide plate, handle, locking nut, thrust bearings, milled screw, base plate, nut, sheath, end cap, screw mandrel.Described block bearing to be bearing on support by axle and on support, to have multicomponent cloth, two pack supports are fixed on respective slide plate, support slide plate group is arranged symmetrically with according to machine axis, described slide plate by guide rail support on unsplit bed(-)plate, hold-down nut on slide plate and the screw mandrel be arranged on base plate fit in kinematic pair, described screw mandrel passes through endoporus and the end cap supporting of base plate, thrust bearings is by screw mandrel axial restraint, the tooth form of screw mandrel is contrary rotation direction mechanism in both sides, after described handle connects rotary screw rod by pin, feed screw nut pair drives two groups of slide plate self-centering polymerizations or separates.The locking of rear screw mandrel tightened by described milled screw, and self-centering bearing bracket workpiece turns round, and milled screw unclamps the diameter change of the adjustable holding workpieces of rear rotary screw rod.
During application, control crank rotary screw rod, drives two groups of slide plates being arranged symmetrically with centripetal or away from central motion, reaches block bearing on support with tangent by holding workpieces cylindrical, then fastening lock-screw.Because the block bearing on support becomes angle of inclination also to arrange in groups with slide plate moving direction, corresponding block bearing can there be is fit supporting to the diameter of work of change.
Accompanying drawing explanation
Accompanying drawing 1 is the present invention's adjustable self-centering bracket figure.Fig. 2 is adjustable self-centering bearing bracket bearing sectional drawing.
Detailed description of the invention
See accompanying drawing, the invention provides a kind of adjustable self-centering bracket, comprise block bearing 1, axle 2, support 3, slide plate 4, handle 5, locking nut 6, thrust bearings 7, milled screw 8, base plate 9, nut 10, sheath 11, nut 12, slide plate 13, support 14, end cap 15, screw mandrel 16.Described block bearing 1 to be bearing on support 3 by axle 2 and to have multicomponent cloth on support 3, and two pack supports 3, support 14 are fixed on respective slide plate 4 and slide plate 13, and two pack support slide plate groups are arranged symmetrically with according to machine axis.
Described slide plate 4 and slide plate 13 by guide rail support on unsplit bed(-)plate 9, hold-down nut 10 on slide plate 4, slide plate 13 and hold-down nut 12 fit in kinematic pair with the screw mandrel 16 be arranged on base plate 9, described screw mandrel 16 is by the endoporus of base plate 9 and end cap 15 supports, thrust bearings 7 by screw mandrel 16 axial restraint, the tooth form of screw mandrel 16 is contrary rotation direction mechanism in both sides.
After described handle 5 connects rotary screw rod 16 by pin, feed screw nut pair drives two groups of slide plate self-centering polymerizations or separates.Described milled screw 8 is tightened rear screw mandrel 16 and is locked, and self-centering bearing bracket workpiece turns round, and milled screw 8 unclamps the diameter change of the adjustable holding workpieces of rear rotary screw rod 16.
Block bearing on described support becomes angle of inclination and arranges in groups with slide plate moving direction, can have corresponding block bearing to fit supporting to the diameter of work of change.
