Summary of the invention
The purpose of this utility model is to realize above-mentioned purpose, provide a kind of before milling the limit with the plate of deflection by both sides to the central sill centering in milling edge element center symmetric position, with edges of boards linearity and dimensional accuracy after the raising milling, this device can carry out centering and centering from two edges of boards to the plate of certain width scope.
For reaching above-mentioned purpose, this plate milling unit numerical control centralising device adopts following technical scheme:
A kind of plate milling unit numerical control centralising device, comprise servomotor, double extension shaft reductor, reducer pedestal, Chang Liang, to central sill and two-way actuating unit, actuating unit comprises: shaft coupling, power transmission shaft, bevel gear, bearing support block, leading screw, clamping plunger oil cylinder seat, jackscrew, Crashworthy plate, single direction thrust ball bearing, bearing, plunger, nut seat, symmetrical guide rail, track base, screw.Servomotor is fixedly connected on the reducer pedestal after connecting the double extension shaft reductor, the double extension shaft reductor connects the shaft coupling of two-way actuating unit respectively, shaft coupling is by turning cylinder coupling cone gear, bevel gear connects leading screw, activity is provided with two screws on the leading screw, two screws are fixedlyed connected with nut seat, the fixedly connected clamping plunger of nut seat oil cylinder seat, long beam is by plunger and jackscrew and the flexible connection of clamping plunger oil cylinder seat, to central sill one end and long beam fixed installation, to the fixedly connected Crashworthy plate of the central sill other end, described nut seat is movably arranged on the symmetrical guide rail, and symmetrical guide rail is fixedly connected in the track base, fixedly connected two bearings of track base, track base fixedly mounts single direction thrust ball bearing near the fixedly connected bearing supporting seat of bevel gear one end on the bearing support block, single direction thrust ball bearing and leading screw flexibly connect.
Beneficial effect of the present invention:
Central sill is done rectilinear motion by two sleeve screw rod screw mechanisms from 2 promotions of its front end, and this two sleeve screw rods screw mechanism power is from same motor.About two groups central sill adopted motor, reductor and the part of model of the same race, and simultaneously from the starting of symmetrical position and stop simultaneously, to the central sill positioning accuracy by electrical Location precision and the decision of mechanical accumulated error.Plate milling unit numerical control centralising device has simple and compact for structure, reasonable in design and characteristics such as positioning accuracy height, and that has satisfied different in width and specification steel plate mills limit centering needs.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Fig. 3 is that the B-B of Fig. 1 is to cutaway view.
The specific embodiment
A kind of plate milling unit numerical control centralising device as shown in Figure 1 to Figure 3 comprises servomotor 1, double extension shaft reductor 2, reducer pedestal 20, long beam 8, to central sill 9 and two-way actuating unit 21, it is characterized in that described actuating unit comprises: shaft coupling 3, power transmission shaft 4, bevel gear 5, bearing support block 6, leading screw 7, clamp plunger oil cylinder seat 10, jackscrew 11, Crashworthy plate 12, single direction thrust ball bearing 13, bearing 14, plunger 15, nut seat 16, symmetry guide rail 17, track base 18, screw 19, described servomotor is fixedly connected on the reducer pedestal 20 after connecting double extension shaft reductor 2, double extension shaft reductor 2 connects the shaft coupling 3 of two-way power drive mechanism 21 respectively, shaft coupling is by turning cylinder 4 coupling cone gears 5, bevel gear 5 connects leading screw 7, activity is provided with two screws 19 on the leading screw 7, two screws 19 are fixedlyed connected with nut seat 16, nut seat 16 fixedly connected clamping plunger oil cylinder seats 10, long beam 8 flexibly connects by plunger 15 and jackscrew 11 and clamps plunger oil cylinder seat 10, to central sill 9 one ends and long beam 8 fixed installations, to the fixedly connected Crashworthy plate 12 of central sill 9 other ends, described nut seat 16 is movably arranged on the symmetrical guide rail 17, symmetry guide rail 17 is fixedly connected in the track base 18, track base 18 fixedly connected two bearings 14, described track base 18 is near the fixedly connected bearing supporting seat 6 of bevel gear one end, fixed installation single direction thrust ball bearing 13 on the bearing support block 6, single direction thrust ball bearing 13 flexibly connects with leading screw 7.
Because the exclusive mechanism of two-way power 21 structures are identical, be connected in double extension shaft reductor 2 jointly, after connect lengthening bar 8 again respectively, about the position is divided when just connecting lengthening bar 8, its two Crashworthy plate and two milling unit center lines distance separately equate fully, guarantee that like this error of centralization only depends on the difference of 2 place's mechanical characteristics of motor and the mechanical accumulated error of mechanical system, guarantees the needs of accuracy of alignment to greatest extent.
Before centering, the oil cylinder pressurize is stretched out in plunger 15 oil pocket oil-feeds to central sill.Pre-outreach is accurately adjusted by jackscrew 11.Can satisfy the centering requirement fully.
After the centering centering is finished central sill is retreated into a home, fix to clamp clamp by clamping clip and front end behind the oil pressure that moves forward and backward on the walking cart and live plate, the walking cart carries out mobile milling.In order to prevent that screw mandrel screw pair is caused motor not reverse by asphyxia by external pressure on the chest and abdomen in the centering process, central sill has been adopted the hydraulic pressure yielding, promptly limit thrust is in the stressed permissible range of plunger case.Before central sill is moved, earlier clamping cylinder is suppressed promotion central sill is stretched out certain distance, by the hydraulic system pressurize.When screw drives central sill is moved centering until stopping, having thrust to exist central sill and edges of boards.When motor need reverse, the release of plunger cylinder elder generation was unloaded thrust and is removed, and having avoided that central sill and plate rigidity are clamped the motor of appearance can't reversal development.
Above-described only is preferred embodiment of the present utility model.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model,, can also make other equivalent modifications and improvement, also should be considered as protection domain of the present utility model as the common practise of mechanical field.
