The purpose of this utility model can also further realize by following technical measures.
The special-purpose centre frame of aforesaid horizontal lathe, wherein said supporting rollern arm body is provided with vertical elongated slot, and several securing members pass vertical elongated slot fixedlys connected with pedestal; Supporting rollern arm body downside is provided with the longitudinally guiding bar, and the pedestal upside is provided with the longitudinally guiding groove, described longitudinally guiding bar and gathering sill matched in clearance; Setting-in bearing in the described roller.
The utility model is simple in structure, easy to use, and good rigidly, intensity height have been eliminated the vibration of workpiece to be machined, have prolonged the service life of cutter.The utility model adopts the roller wheel bearing workpiece of a pair of setting-in bearing, has replaced sliding friction pair with rolling friction pair, and rolling wheel wear is very little, and the workpiece to be machined surface can not produce cut, has improved the surface quality of workpiece to be machined.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises pedestal 1, clamping plate 2, a pair of supporting rollern arm 3, a pair of stopping means 4, pedestal 1 is an overall structure, its both sides stretch out into splayed, its bottom supporting is on lathe bed 5, the V-shaped groove 11 of pedestal 1 bottom drops on the bed ways 51, and pedestal 1 is positioned on the lathe bed 5.Clamping plate 2 is arranged on the downside of bed ways 51, and trip bolt 52 passes pedestal 1 downside fixedlys connected with clamping plate 2, and pedestal 1 is fixed on the lathe bed 5.
3 one-tenth splayed symmetries of a pair of supporting rollern arm are tilting at pedestal 1 upside, supporting rollern arm 3 comprises supporting rollern arm body 31, roller 32, roller shaft 33, setting-in bearing 34 in the roller 32, one pair roller, 32 positions relatively are embedded in the prong of supporting rollern arm body 31 the inners respectively, roller shaft 33 passes supporting rollern arm body 31 inner and bearings 34, makes that roller 32 and supporting rollern arm body 31 are hinged.The bearing 34 of present embodiment is a rolling bearing, also can select sliding bearing for use or directly rolling bearing is used as roller 32.Supporting rollern arm body 31 is provided with vertical elongated slot 311, is used to regulate the relative position of a pair roller 32, to adapt to the workpiece that supports different-diameter.The fastening stud 35 of two supporting rollern arms passes vertical elongated slot 311, fixedlys connected with pedestal 1 by two clamp nuts 36.Supporting rollern arm body 31 downsides are provided with longitudinally guiding bar 312, and pedestal 1 upside is provided with longitudinally guiding groove 12, and longitudinally guiding bar 312 and gathering sill 12 matched in clearance can be to supporting rollern arm body 31 cross spacings; When supporting rollern arm body 31 on pedestal 1 during side shifting, longitudinally guiding bar 312 plays guide effect.
Stopping means 4 is arranged on the outer end of supporting rollern arm body, comprise holder 41, fastening screw 42, holder 41 is fixed on pedestal 1 outer end by trip bolt 43, fastening screw 42 screws on holder 41, fastening screw 42 tops are resisted against the outer end of supporting rollern arm body 31, and by locking nut 44 locking fastening screws 42.When workpiece 6 is placed on the utility model, a pair of supporting rollern arm 3 is owing to be subjected to the component effect to the pedestal lateral direction that workpiece 6 deadweights produce, move to pedestal 1 lateral direction, supporting arm stopping means 4 can withstand support roller arm 3 at this moment, prevents its downslide.
