Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Fig. 1 ~ Fig. 3, the utility model comprises tailstock body 1, tail spindle, tail spindle sleeve 9, manual control mechanism, buffer spring 10 and automatic controls, described tail spindle sleeve 9 fixed lateral is arranged at described tailstock body 1, described tail spindle is threaded onto tail spindle sleeve 9 axially extending bore one end towards workpiece, tail spindle sleeve 9 is provided with the end face shoulder towards left end on the periphery of left end end, tail spindle sleeve 9 left end end winding support is connected with baffle ring 11, buffer spring 10 is set in described tail spindle sleeve 9 left end and two ends are resisted against described baffle ring 11 and end face shoulder respectively, described manual control mechanism comprises handle 3, rack-and-pinion, rotating shaft and pinion stand 2, pinion stand 2 is flush-mounted in described tailstock body 1, pinion stand 2 is provided with the pinion mounting holes perpendicular to described tail spindle sleeve 9, the gear 12 of described rack-and-pinion is supported by axle and is installed in described pinion mounting holes, gear 12 installing hole is provided with a radial opening groove, a part for described gear 12 is made to be exposed at outside pinion mounting holes, the tooth bar 13 of rack-and-pinion is arranged at described tail spindle sleeve 9 periphery towards gear side along the axis direction of tail spindle sleeve and engages each other with described gear 12, described end, axle one end is fixedly connected with described handle 3 one end, by rotary handle 3, band moving axis and gear 12 rotate, because gear 12 and tooth bar 13 engage, drive tooth bar 13 axially-movable, thus make tail spindle sleeve 9 axially-movable, described automatic controls comprises oil cylinder, connecting axle 8, linking arm 6, disc spring 4 and adjustment runner 5, oil cylinder is fixed on described tailstock body 1, oil cylinder is connected with pressure source by pipeline, and the magnetic valve controlling oil cylinder can control to open or cut out by control button or floor push, described connecting axle 8 one end is fixedly connected with described tail spindle sleeve 9 right-hand member, described linking arm 6 two ends are fixedly connected on described cylinder piston rod 7 and connecting axle 8 other end respectively, described adjustment runner 5 is set in described connecting axle 8 right-hand member and is threaded connection between the two, and regulate runner 5 to be made up of side by side two nuts, all be set in connecting axle 8 right-hand member, play axial location to linking arm 6 to regulate and positioning action, two nuts effectively can improve positioning action, described disc spring 4 is set in described connecting axle 8 and two ends are resisted against on described linking arm 6 and tail spindle sleeve 9 right-hand member end face respectively, drive linking arm 6 and connecting axle 8 and tail spindle sleeve 9 to slide axially when cylinder piston rod 7 piston movement.
