Abstract
An adjusting self-centering bracket comprises supporting bearings, shafts, supports, sliding plates, a handle, a locking nut, a thrust bearing pack, a knurled screw, a base plate, nuts, a protective sleeve, an end cover and a lead screw. The multiple sets of supporting bearings are supported and distributed on the supports through the shafts. The two supports are fixed to the sliding plates correspondingly. The supports and the sliding plates are symmetrically arranged according to the central line of a machine tool. The sliding plates are supported on the whole base plate through a guide rail. The lead screw is axially fixed to the base plate. Tooth forms on the two sides of the lead screw are opposite in rotation direction. After the handle is in pin joint with the lead screw and rotates the lead screw, a screw-nut pair drives the two sliding plates to get close to or get away from each other in a self-centering mode. The lead screw is locked after the knurled screw is screwed. The diameter change of a supported workpiece can be adjusted by rotating the lead screw after the knurled screw is unscrewed.
Description
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, generally use the supporting of manual center frame, or use self-centering hydraulic pressure center frame supporting, but when workpiece is relatively heavy, the carrying of common manual centre frame is inadequate, and hydraulic center frame generally turns round enclosed construction, and workpiece loading and unloading is inconvenient.
Summary of the invention
In order to more preferably realize the carrying of machine tooling medium and heavy shaft-like workpiece, the present 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, the compound action moved by symmetrical two groups of supporting-points, realizing the supporting to heavy-type shaft-series workpieces to regulate, the work-handling of supporting is efficient and convenient.
The technical scheme is that the adjustable self-centering bracket for the carrying of machine tooling medium and heavy shaft-like workpiece, including block bearing, axle, support, slide plate, handle, locking nut, thrust bearings, milled screw, base plate, nut, sheath, end cap, screw mandrel.Described block bearing is bearing on support by axle and has multicomponent cloth on support, two pack supports are fixed on respective slide plate, support slide plate group is arranged symmetrically with according to machine axis, described slide plate passes through guide rail support on unsplit bed(-)plate, fixing nut on slide plate fits in kinematic pair with the screw mandrel being arranged on base plate, described screw mandrel is supported by endoporus and the end cap 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 couples 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 rear rotary screw rod scalable supporting workpiece.
During application, control crank rotary screw rod, drive two groups of slide plates being arranged symmetrically with centripetal or away from central motion, reach block bearing on support with to be supported by excircle of workpiece tangent, then fasten lock-screw.Owing to the block bearing on support becomes angle of inclination with slide plate moving direction and arranges in groups, corresponding block bearing can be had to fit supporting to the diameter of work of change.
Accompanying drawing explanation
Accompanying drawing 1 is scalable self-centering bracket figure of the present invention.Fig. 2 is adjustable self-centering bearing bracket bearing sectional drawing.
Detailed description of the invention
See accompanying drawing, the present invention provides a kind of scalable self-centering bracket, including 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 is bearing on support 3 and has on support 3 multicomponent cloth by axle 2, 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 pass through guide rail support on unsplit bed(-)plate 9, fixing nut 10 and fixing nut 12 on slide plate 4, slide plate 13 fit in kinematic pair with the screw mandrel 16 being arranged on base plate 9, described screw mandrel 16 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 couples 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 rear rotary screw rod 16 scalable supporting workpiece.
The described block bearing on support becomes angle of inclination and arranges in groups with slide plate moving direction, corresponding block bearing can be had to fit supporting the diameter of work of change.
