Description

Die spotting hydr aulic presses machine fine motion mode device

Technical field

The utility model relates to a kind of die spotting hydr aulic presses machine fine setting mode device.

Background technology

Precision die all will place upper and lower mould the bedding-in hydraulic press to carry out repeatedly to mould bedding-in, correction in manufacture process.General lower mould is fixed on the underbeam workbench of bedding-in hydraulic press, upper mould is placed on the slide block between the upper and lower beam of bedding-in hydraulic press, promote slide block movement by Hydrauservo System, make upper mould and counterdie press matched dies, revise then, so repeated multiple times operation is until reaching the upper and lower mould quality of fit.The shortcoming that above-mentioned traditional bedding-in hydraulic press mode device exists is, the operation control stability is not good, and it is high that positioning accuracy is owed.

Summary of the invention

The purpose of this utility model provides a kind ofly to mould positioning accuracy height, and controls reliable and stable die spotting hydr aulic presses machine fine motion mode device.

The technical solution that realizes above-mentioned purpose is: it is by the reduction gearing mechanism that is installed on the movable spacing screw mandrel on the hydraulic press upper beam, the micro drive that drives reduction gearing mechanism constitutes with the master cylinder that is installed on the driving slide block on the hydraulic press upper beam, described micro drive is by the driving oil cylinder that is connected on the hinge seat, be connected with the piston rod that drives oil cylinder, be socketed on the connecting plate that drives on the output shaft simultaneously, being fixed in the ratchet and the end that drive on the output shaft is hinged on the connecting plate, ratchet that the other end and ratchet are matched and ratchet stage clip are formed, also be fixed with a press strip on the piston rod leading section of driving oil cylinder, this press strip leading section is overlapped on the ratchet upper rear end; The reduction gearing mechanism of movable spacing screw mandrel is by intermeshing worm and wormwheel and be connected in the worm gear bottom and form with the nut that worm gear is positioned on the same central axis, movable spacing screw mandrel is rotatably connected in the nut, axial flat key on its surface offers axial slide and is fixed in the worm gear inwall matches, and worm screw then is connected with the driving output shaft of micro drive by shaft coupling; The pull bar that the lower end is connected with slide block passes the axial center hole of movable spacing screw mandrel vertically upward, and its upper end is equipped with the spacing flange that matches with movable spacing screw mandrel upper surface.

During this device inactive state, the spacing flange of slide block pull bar upper end and the upper surface of movable spacing screw mandrel are contacted.When needs are done the die worker, start micro drive, the piston rod that drives oil cylinder stretches out according to the stroke of setting, promote connecting plate and do the rotation of certain angle around driving output shaft, drive oil cylinder simultaneously also around hinge seat rotation certain angle, so press strip is thrown off ratchet, ratchet contacts and promotes the ratchet α that rotates to an angle immediately with ratchet under the effect of stage clip, drive worm screw and also rotate the α angle, and then worm-drive worm gear, the spacing screw mandrel of worm gear drives activity rotates identical angle, movable spacing screw mandrel has rotated an angle simultaneously again in nut, one section small distance has promptly descended, the last plane of movable spacing screw mandrel has been broken away from and the contacting of the spacing flange in slide block pull bar upper end, and this moment, master cylinder under low pressure drove the slide block down slight distance, and the slide block pull bar is descending thereupon, when its spacing flange touched on the movable spacing screw mandrel plane again, slide block down was obstructed.Because the stroke that the driving oil cylinder piston bar of micro drive stretches out is set, after starting, stretch out to reach and promptly return voluntarily after setting stroke, the press strip of oil cylinder piston bar front end connection at this moment props up again and is pressed in the ratchet rearward end and overcomes the spring force of stage clip to ratchet, the ratchet leading section is lifted break away from and the contacting of ratchet, so promptly finish once fine setting slide block.Like this repeatable operation can make the slide block that patrix the is installed same small distance that repeatedly descends.The utility model scientific structure, reasonable, transmission is reliable and stable, and is easy and simple to handle, realized the high accuracy fine setting to slide block positioning accuracy≤0.05mm.

The specific embodiment

The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.

In the bedding-in hydraulic press, the counterdie of processing mold is installed on the underbeam platform 13 of hydraulic press, patrix is installed on the slide block 12 of hydraulic press, four jiaos on plane is connected with four by adpting flange 32 and passes put the beams in place 1 pull bars 11 of hydraulic press vertically upward on the slide block 12, and pull bar 11 upper ends are provided with spacing flange 28; The master cylinder 8 of direct drive slide block 12 displacements is installed on the platform of hydraulic press upper beam 1, be equipped with cooperate four pull bars 11 respectively four groups simultaneously by intermeshing worm screw 3, worm gear 17 and being fixed in is put the beams in place on 1 and is positioned at the reduction gearing mechanism 2 of the movable spacing screw mandrel that the nut 10 on the same central axis forms with worm gear, movable spacing screw mandrel 30 is rotatably connected in the nut 10, axial flat key 29 on its surface offers axial slide and is fixed in worm gear 17 inwalls matches, the lower end is equipped with lower limit flange 31, and slide block pull bar 11 passes the axial center hole of movable spacing screw mandrel 30, and the spacing flange 28 of its upper end matches with the last plane of movable spacing screw mandrel 30; Be in its worm screw one group of micro drive is installed between a pair of reduction gearing mechanism 2 on the same axis, this micro drive 6 is by the driving oil cylinder 19 that is connected on the hinge seat 18, be connected with the piston rod 26 that drives oil cylinder 19, be socketed on the connecting plate 20 that drives on the output shaft 5 simultaneously, be fixed in the ratchet 21 that drives on the output shaft 5 with key 27, be connected with connecting plate 20 with hinge 24 with an end, ratchet 23 that the other end and ratchet are matched and ratchet stage clip 22 are formed, drive on oil cylinder piston bar 26 leading sections and also be fixed with a press strip 25, the leading section of press strip 25 is overlapped on ratchet 23 upper rear end; One side drive output shaft 5 of micro drive directly is connected with the worm screw 3 of the reduction gearing mechanism that is positioned at this side by shaft coupling 4, opposite side drives 5 of output shafts and is connected by the worm screw 3 in the reduction gearing mechanism of T type steering box 7 and this side, and the vertical axis 14 of T type steering box 7 is directly driven by motor 15.The vertical axis 14 of two groups of relative T type steering boxs 7 of present embodiment links into an integrated entity by connecting axle 16, and is driven simultaneously by a motor 15.When slide block 12 needs more greatly apart from fast offset, but starter motor 15 drives connecting axle 16, and by T type steering box 7, the worm screw 3 in each reduction gearing mechanism of transmission is rotated continuously, thereby the spacing screw mandrel 30 of drive activity rises greatly or descends.The position of movable spacing screw mandrel 30 is measured by the rotary encoder 9 that is connected and installed on the worm screw 3.
