Operation principle of the present utility model is:
Jacking trolley and straddle truck, side plate group are to frock, positioner interoperation step:
Jacking trolley coordinates with the straddle truck frock, the base plate that assembly welding is good lifts to jacking trolley from the protheca station, straddle truck is to adopt beam type structure, and the driven by servomotor ball screw type elevator drives the frock that the electromagnet sucker is housed and draws workpiece, all around moves up and down;
1. straddle truck picks up from the front station base plate that assembly welding is good (how the base plate that assembly welding is good omits from the process that the protheca station picks up, after following article straddle truck picks up workpiece how with the flow process that coordinates of jacking trolley), with the base plate assembly along rail moving to the casing group to station;
2. after arriving casing assembling station, straddle truck crossbeam transverse shifting moves to jacking trolley top (position of dolly longitudinal direction is pre-set position, and namely flow process of same workpiece is covered, the initial position that dolly returns) with base plate;
3. in the local time that the straddle truck cross beam movement is to the jacking trolley, the straddle truck crossbeam drops to assigned address;
4. after straddle truck drops to assigned address, the whole lifting mechanism of jacking trolley is with the lifting support jack-up that makes progress, the jacking head of a lifting body rises to peak, the secondary lifting body rises to assigned address, this moment, each lifting body all touched the base plate workpiece, secondary lifting body and clamp mechanism clamp action, the width left and right clamps the base plate workpiece, the outage of straddle truck electromagnet, the base plate workpiece falls on jacking trolley, this moment each lifting body and the lifting support original position that all falls back, the electromagnet of secondary lifting body gets electric, hold the base plate face, at this moment, the straddle truck crossbeam rises, laterally regain, and move to the protheca station and prepare to carry out next action,
So far, the interoperation of jacking trolley and straddle truck is completed;
5. need this moment manually the perpendicular gusset on base plate, horizontal bar board component to be welded up;
Straddle truck omits coordinating herein of frock with the side plate group, and straddle truck is with on left side plate device for hoisting biside plate frock;
6. this moment, casing group case preparation was substantially complete, the action of base plate initial alignment, base plate is moved to needed position, large end location, be that the U-shaped groove that the pull bar of initial positioning mechanism catches on base plate moves to assigned address, the clamp of secondary lifting body and electromagnet be in all the time clamp and electric magnetic state;
7. this moment, the side plate group turn to the upright position to frock by horizontal level;
8. the side plate frock that is turned to plumbness moves the arrival assigned address to the centre, namely left side plate moves to horizontal bar Board position (the horizontal bar plate is namely that casing is strengthened gusset, also can be used as spacing that left side plate moves simultaneously);
9. dolly lifting this moment support is raised to the highest;
10. be starting point by the secondary lifting body, successively each lifting body lifting put in place, make the base plate side plate of tightly fitting;
11. robot carries out automatic welding, and base plate and plate-side plate welding is firm;
after 12. welding is completed, the side plate group is not loose to the frock electromagnet, clamped position is constant, this moment is by the absorption affinity of side plate group to the frock electromagnet, and the side plate group is to the clamping force of frock, the situation that makes workpiece keep welding to complete, the clamp of secondary lifting body unclamps afterwards, the lifting support drops to extreme lower position, this moment, jacking trolley broke away from workpiece fully, except the secondary lifting body, other lifting body all drops down onto low level, jacking trolley vertically moves, make jacking trolley move to the centralized positioning position by large end location, the position that this moment, the secondary lifting body designed in advance according to system, tightly hold workpiece with servomotor accurate adjustment to secondary lifting body, electromagnet outage loss of excitation, the side plate group is returned frock former road, so far, the casing action that accesses after assembly welding of large switching center9 location, end location and jacking trolley is completed,
13. jacking trolley is vertically walked, and workpiece is transported to next station;
after 14. dolly longitudinally moves to next station desired location, two-seater positioner beam integral body drops to the precalculated position, jacking trolley lifting support rises to precalculated position (servo system control), the secondary lifting body rises to precalculated position (servo system control), the swivel mount that be arranged on crossbeam this moment rotates to the good casing of assembly welding, promote to hook and get workpiece, rise to the precalculated position, step up the centering body action after completing, make the axis of workpiece be in positioner crossbeam center, the positioner crossbeam rises overally to the welding position, positioner accesses workpiece and completes, complete smoothly handing-over with jacking trolley, this moment, jacking trolley was back to by former road the initial position that upper cover station accesses base plate,
Be exactly more than the complete course of work of jacking trolley in the jib production line.
The beneficial effects of the utility model are: the utility model utilizes whole lifting mechanism with the lifting of lifting support, each jacking head carries out a lifting, the secondary lifting body carries out the secondary jacking, thereby make each jacking head to apply jacking force upwards to base plate according to the base curve of biside plate, make base plate fit the preferably base of side plate, facilitate welding robot to weld, Product Precision is high; Whole process automation degree is high, can coordinate the action of side plate automatically to complete the group case work of jib, simultaneously with respect to manual operations, operating efficiency improves, operates also easy greatly, thereby the reduction labor intensity of operating staff is conducive to factory and reduces production costs, and satisfies production requirement.
