Technical solution of the present invention is described further by detailed description of the invention below in conjunction with accompanying drawing.
Detailed description of the invention
As Figure 1-3, column crane mast section rotary tooling, comprise underframe 1 and rotating mechanism 2, rotating mechanism is rotationally connected with underframe 1 by the major axis 3 at its two ends and minor axis 4, rotating mechanism 2 is made up of two end wall panels 5 and the joint pin 6 that is connected to two end wall panel corners, an end wall panel is wherein provided with fixed main swing arm locating shaft 7, and the correspondence of other end wallboard is provided with the main swing arm jacking mechanism 8 of flexible location.
As shown in Figure 4, jacking mechanism comprises handwheel 9, linkage board 10, screw mandrel 11, locating shaft 12, positioning shaft sleeve 13, screw mandrel overcoat 14 and tight sleeve 15, positioning shaft sleeve 13 and screw mandrel overcoat 14 fixed cover are in wallboard preformed hole, locating shaft 12 slip cap is in positioning shaft sleeve, its outer end is fixedly connected with linkage board 10, the joint sleeve of inner end and main swing arm end fixing hole 16 coordinate; Screw mandrel 11 is enclosed within screw mandrel overcoat 14, and coordinates with screw mandrel overcoat right-hand member internal thread part, the front portion of screw mandrel and tight sleeve 15 threaded engagement, and afterbody is fixedly connected with handwheel through the hole of linkage board 10; Tight sleeve 15 one end to be actively set in screw mandrel overcoat and to be limited to rotate.
As shown in Figure 5, anterior 111 external diameters of screw mandrel are less than rear portion external diameter and the anterior thread pitch coordinated with tight sleeve is 1/2 of the thread pitch at screw mandrel rear portion 112, and the afterbody of screw mandrel is provided with the stopper section 113 of fixing linkage board.
As shown in Figure 6, tight sleeve is T-type structure, and be made up of the cannula portion 152 pushing against portion 154 and front end band internal thread 151, cannula portion outer wall is axially arranged with keyway 153; As shown in Figure 1, screw mandrel overcoat 14 corresponds to the keyhole 20 that keyway 153 is provided with fitting key.
As Figure 7-8, rotary tooling is also provided with the location backup plate 19 for positioning support bracer 17, and location backup plate is fixedly connected on the joint pin 6 corresponding to back-up block, comprises location division, back-up block bottom side 191 and left positioner portion 192.
On main chord during frock, be transferred to prefabricated position and rotate handwheel to hold out against main chord, namely handwheel drives screw mandrel to rotate, screw mandrel rear end spiral in the internal thread hole of screw mandrel overcoat right-hand member, screw mandrel produces stroke left, drive locating shaft to left movement by linkage board, and screw mandrel to rotarily drive tight sleeve protruding in screw mandrel overcoat, it is final when locating shaft enters into the optimum position of the fixing hole of main swing arm outer tube, tight sleeve just in time pushes against main swing arm end, after operation like this makes main chord all hold out against four times, at the assembled standard knot web member of rotating mechanism, the anglec of rotation is regulated to reach the position being conducive to welding time assembled.During back-up block location, as Figure 7-8, after back-up block is placed at backup plate place, location, spot welding makes it fix.So far assembled operation completes and enters welding sequence, regulates the anglec of rotation of rotating mechanism to make its position resting on convenient welding carry out welding.
After having welded, unscrew jacking mechanism handwheel and exit positioning sleeve completely to alignment pin, after four jacking mechanisms exit completely, use driving to be hung out by standard knot.
