Specific embodiment

Below in conjunction with accompanying drawing the utility model is further described, but the utility model is not limited only to this embodiment.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, centralized positioning 1 is installed in center above the geared head; Pay-off 2 links to each other with frame by fixed support 22, is contained in rotary oil cylinder one side; Tooth grinding device 3 is installed in the back cross slide.On geared head rear side, the main shaft; Sliding sleeve 10, insulation board 15, vertical hydraulic cylinder 14, slide plate 16 forms a whole by screw, slide bar 11 is contained in 10 li of sliding sleeves, vertical piston 12 is contained in 14 li in vertical hydraulic cylinder, can be according to hydraulic principle in movement in vertical direction, promoting slide bar moves vertically downward, spring 13 and slide bar 11, vertical hydraulic cylinder 14 links to each other, slide bar is moved vertically upward, horizontal hydraulic cylinder 17 is fixed on the geared head position intermediate, horizontal piston 18 is contained in the horizontal hydraulic cylinder 17 and passes through screw, baffle plate links to each other with slide plate 16, can do horizontal motion according to hydraulic principle, drive slide bar 11 and do side-to-side movement in the horizontal direction, thereby slide bar 11 can be in level, vertical both direction motion, adjustable screw 19 is contained in above the geared head, is leaning on that side of rotary oil cylinder; Pulley 20 is contained on the fixed support 22, nylon rope is connected with pulley 20, sash weight 23, feeding pulley pivoted housing 26, fixed support 22 links to each other with frame by screw, fixed block pivoted housing 24 is fixed on guide rail 25 by rotary oil cylinder one end, guide rail 25 forms a whole with fixed support 22, supporting seat 27, feeding pulley pivoted housing 26 is contained on the guide rail 25, and gun barrel 28 is contained on the feeding pulley pivoted housing 26, and bar 29 is contained in the nylon jacket of feeding pulley pivoted housing 26, fixed block pivoted housing 24; Timing belt pulley 31 is contained in respectively on main shaft, the Hooks coupling universal coupling 33, bearing fixed seat 32 is fixed on the geared head by screw, Hooks coupling universal coupling 33 is contained on the speed-changing gear box respectively, belt 34 is contained on the tooth belt wheel 31, connecting axle 35 links to each other with Hooks coupling universal coupling, mill dental lamina 36 and be contained on the speed-changing gear box 37, speed-changing gear box is contained on the cross slide of back.

Directly act on the slide bar 11 owing to the material impulsive force during use, thereby vertical piston 12 does not link to each other with slide bar 11 and is protected, the direction of horizontal piston 18, slide plate 16 movable directions and impulsive force influences very little on same straight line, thereby has prolonged the service life of whole positioner; When material can drop when chewing slide bar 11 length from folder automatically; guaranteed to be not less than the distance of slide bar 11 in horizontal movement by folder length, it is more accurate to locate, and can protect cutter simultaneously; reduce to whet a knife, than size, the worry adorning cutter, unload cutter, improve quality, precision, the efficient of workpiece processing.

The feeding pulley pivoted housing 26 of bearing and nylon jacket is housed respectively, and fixed block pivoted housing 24 has replaced seamless steel pipe, and during work, bar 29 rotates with main shaft with nylon jacket, bearing and reduced noise, improves working environment.

Because main shaft rotates two timing belt pulleys 31 of drive and synchronously rotates, bearing block 32 can make the Hooks coupling universal coupling 33 stable rotations of not beating, synchronous belt is swung 31 gears by Hooks coupling universal coupling 33, connecting axle 35 driven gear gearboxes 37 and is synchronously rotated, drive by the speed-changing gear box output shaft and to mill dental lamina 36 and do and be synchronized with the movement, having realized milling dental lamina 36 like this does with main shaft and is synchronized with the movement, mill 36 pairs of workpiece to be machined milling threads of dental lamina, what so just increased the automatic hydraulic lathe mills the tooth function, has enlarged the scope of application of automatic hydraulic lathe.
