The specific embodiment
With reference to the accompanying drawings, the specific embodiment of the present utility model is described in further detail.
The positioner clamping tooling of the jib production line shown in accompanying drawing 1, its main body is horizontally disposed and a strip portal frame that two ends are connected with positioner respectively, and this portal frame comprises parallel and two case beams 4 keeping at a certain distance away and two connecting plates 5 that respectively end at two ends, two case beam left and right fixedly are connected as a single entity; The top of this gate-type skeleton frame is equipped with two top detent mechanisms 1, is symmetrically installed with respectively at least two group centering bodies 2 and at least two group supporting mechanisms 3 on the both sides case beam of gate-type skeleton frame.
In the detent mechanism of described top (referring to Fig. 2, Fig. 3, Fig. 4), a line slide rail A1 who arranges is along its length installed respectively on the top of both sides case beam, and the bottom at locating rack A10 two ends is separately installed with the slide block A2 that coordinates with aforementioned line slide rail; Locating rack is positioned on line slide rail by aforementioned slide block, thereby can slides along line slide rail across after crossing both sides case beam.Also be provided with rack and pinion mechanism in detent mechanism, comprising being arranged on case beam side and along the tooth bar A3 that case beam length direction stretches, this driven wheel of driven wheel A4(that is installed with on locating rack with aforementioned tooth bar engagement fit is arranged on the output shaft of reductor A6); The preferred servomotor of motor A5() start reductor (preferred planet-gear speed reducer; This reductor is fixed on speed reducer mounting base) driven, locating rack just is being driven along line slide rail and is sliding.
Also configure a flexible coupling components (referring to Fig. 5) in rack and pinion mechanism; Wherein, have several ovals holes on speed reducer mounting base, several (showing 4 in Fig. 5) fairlead A15 are fixed on locating rack after passing one by one respectively the oval hole, make speed reducer mounting base to slide on locating rack; Two adjustment screw A16 pass through respectively and are horizontally fixed on the side of locating rack, it is anterior and locating rack is applied pressure on top surface that the end of two spring A12 respectively is set on an adjustment screw by a spring housing, the other end of two springs respectively the top press be fixed on speed reducer mounting base with projection A13(projection) another spring housing of coordinating of grafting.Speed reducer mounting base keeps driven wheel A4 and tooth bar A3 gapless driving under the pressure on top surface effect of above-mentioned spring, simultaneously rack-and-pinion is played a protective role.
In described supporting mechanism (referring to Fig. 6, Fig. 7): the guide post B10 of tubulose vertically inserts in the slide opening of case beam, the top of guide post is fixed by the external toothing of mounting disc B14 and horizontally disposed external tooth type pivoting support B13, the inner ring of external tooth type pivoting support is fixedly connected with the case beam, and enhancing screw B11 interts in guide post; The bottom symmetry of guide post is shaped with the gathering sill B10-1 of two vertical layouts and lateral direction penetrating guide post.It is affixed that the bottom of enhancing screw promotes ear B28 by a bearing pin B27 and screw mandrel, and after gathering sill on guide post is passed through respectively again at the two ends that screw mandrel promotes ear, past both sides level was stretched out and fixed with lifting body pedestal B8; Lifting body B1 is hinged on the lifting body pedestal swingably by a horizontally disposed rotating shaft B3; As seen from the figure: because the postive stop baffle B8-1 of base bottom is nearer apart from the bottom of lifting body, so lifting body can only be in less angular range (be about positive and negative 20 degree) B3 axis oscillating around the shaft.Described hoisting mechanism is the Worm gear feed screw lift B16 that installs in mounting disc, comprise aforesaid enhancing screw, coordinate with enhancing screw and be fixed on the worm gear center screw and with coordinate the worm screw that is driven by servo motor B 17; Obviously, because guide post and mounting disc are fixed, the screw mandrel that the lower end of enhancing screw connects promotes in the gathering sill that ear is embedded in again the guide post bottom enhancing screw can't be rotated, so the rotation of screw namely is converted into vertically moving up and down of enhancing screw.In described slew gear, the preferred servomotor of motor B24() and the worm decelerating machine B23 that matches all be fixed on the case beam, the travelling gear B20 on the power transmission shaft B19 that is driven by worm decelerating machine again with the external toothing engagement of external tooth type pivoting support B13; Electrical power starts, and external toothing i.e. engaged the rotation, rotates around the enhancing screw axis together with guide post, enhancing screw and lifting body thereby drive hoisting mechanism.
Each parts in described centering body all are positioned at installing plate D1 upper (referring to Fig. 8), and installing plate both sides are fixed wtih respectively slide rail D2 central authorities and are fixed wtih the preferred servomotor of motor D 5(), Worm gear feed screw lift D4; The bottom surface of sliding seat D3 (Fig. 8) is fixed wtih two slide block D6 that coordinate with slide rail, the hinged clamp D8 of the front end of sliding seat (right-hand member of Fig. 8); The front end of screw mandrel D9 is connected with sliding seat by bearing, and the screw that coordinates with screw mandrel is fixed in the worm gear of Worm gear feed screw lift.As shown in Figure 1: installing plate is fixed on case beam bottom up, and slide rail stretches toward the width of gate-type skeleton frame; After electric motor starting, the worm drive worm gear rotates screw, and screw mandrel namely produces axially-movable, and then drives sliding seat and clamp moves along slide rail; The centering body work compound that is arranged symmetrically with on the case beam of both sides, clamping tooling can produce the clamping caught workpiece or break away from the operational motion of caught workpiece.
The clamp that described sliding seat is hinged, the axis of its jointed shaft D5 is vertically arranged.In Figure 11 as can be known: due to unlabelled in the front of described sliding seat hinged end and the space D 16(figure between clamp) less, so clamp can only swing in less scope, pressed from both sides the curve form at position to adapt to workpiece.
