Preferably, on front support cylinder, middle support tube and rear support cylinder, be provided with the connecting hole corresponding with screw rod quantity.
Preferably, front support cylinder, middle support tube and rear support cylinder all have sizes specification.
Preferably, the quantity of screw rod is 3.
Preferably, the two ends of middle support tube are provided with arch brace face, and supporting surface inner side is provided with the first chamfering with the central through hole junction of middle support tube, and each end, supporting surface outside is provided with the second chamfering.
Preferably, the fit clearance of self adaptation lathe spindle material pipe and lathe spindle hollow pipe inwall is 0.03～0.05mm.
Use procedure of the present utility model is as follows: first, the utility model is assembled, front support cylinder, rear support cylinder, middle support tube, adpting flange, screw rod, nut are assembled to locking each securing member (wherein, adpting flange is connected with main shaft after filling in main shaft) successively; Afterwards, by the whole lathe spindle inside that is tucked into of the material pipe assembling, the M6 screwed hole fitting by 2 opposite side with the flange of lathe is used M6 bolt to be connected, and guarantee that material pipe and the fit clearance of lathe spindle hollow pipe inwall are 0.03～0.05mm, to guarantee the axiality of barrel and lathe spindle.When processing the bar of different-diameter, only need change the intermediate throughholes diameter of front support cylinder, rear support cylinder, three parts of middle support tube and will increase 0.5mm by bar diameter, can guarantee to expect that pipe through-hole can pass through corresponding bar, the such design of the utility model can meet the process requirements of the bar of various diameters, applied widely.During production, whole bar filled in to end (Fig. 2) plug feed pipe by bar, the logical charge tube of bar leading portion and jig (jig self by radial circumference, arrange with ASA6# inner cone 3 equidistant M12 counter sinks use M12 hexagon socket head cap screws to be connected with the ASA6# outer cone of machine tool chief axis nose and 3 equidistant M12 screwed holes arranging with radial circumference) are also used the built-in collet of jig to clamp can to start metal and process, and operation is very easy.
The utility model design distinguished, in barrel design in the past, adopts hollow assembling, significantly reduces, and can realize standardization assembling and produce in weight.And from the angle of automation, coordinate feeder equipment, can realize whole bar (the longest reach 3 meters) and can process continuously and do not need to cut off bar.On the one hand, save the artificial loading time, on the other hand, reduced the loss of stub bar, good in economic efficiency.In addition, middle support tube of the present utility model is provided with supporting surface, and the angle of respectively holding in supporting surface outside is all set to chamfer shape, has effectively avoided the bar damage that directly processing causes main shaft, has greatly improved machining accuracy.And the utility model is to hot rolling bar, the very poor long bar of cold drawn bar and linearity all can be processed, applied widely.Therefore, compared with prior art, the utlity model has the beneficial effect that machining accuracy is high, working (machining) efficiency is high, processing cost is low, good in economic efficiency, applied widely.
