As shown in fig. 7, operation principle of the utility model white body welding production line with flexible slide unit：

The welding fixture for being equipped with A vehicles is completed to the process for being moved to flexible slide unit welding position from assembling：

(1) the slide unit trolley 10 for being equipped with A vehicle welding fixtures is placed on artificial trolley 54, and promotes artificial trolley 54 545 upper handle of locking unit so that the H-type fixture block 54533 of locking unit 545 is clamped under 10 stent 11 of slide unit trolley The clamping block 124 of first interfacing part 121 on surface, so as to which slide unit trolley 10 is fixed on artificial trolley 54；It is fixedly arranged on slide unit The cam 1312 and secondary side of the universal sliding block 131 of benchmark with guiding and support of 10 stent of trolley, 11 lower surface both sides are universal The cam 1322 of sliding block 132, which is slidably installed in, to come in and go out on slide unit guide rail 542.

(2) guiding of thick guide plate 5262 that the universal wheel 5415 of artificial trolley 54 passes through thick limit assembly 526, tentatively It travels to the periphery of the fine positioning pedestal 521 of detent mechanism 52, plugs locking latch 5415.It is further continued for pushing artificial trolley 54, By smart guide plate 543 in sliding adjustment level disparity on horizontal location cam 5232 so that the height positioning of artificial trolley 54 Cam 544 travels the height and outer mistake on fine positioning cushion block 525 so as to adjust the slide unit guide rail 542 that comes in and goes out of artificial trolley 54 The 46 horizontal slitless connection of outer transition guide on stent 43 is crossed, plugs locking latch 5419, and by the fixation of outer transition bracket 43 The hook arm 4352 of clamping element 435 hooks the offline briquetting 5417 of artificial trolley 54.Artificial trolley 54 and upper offline slide unit list at this time The docking of outer transition bracket 43 of member 40 is completed.

(3) the electrical quick-inserting part bearing 16 under 10 main body rack 11 of slide unit trolley and automobile model recognizer bearing 15 dock respectively Air source by line on detent mechanism 92 inserts connection air source and carries out checking that debugging and vehicle are identified soon.After the completion of debugging, motor The clamping geosynclinal block of the dragging mechanism of upper offline power buggy on guide rail 522 is by air cylinder lifting so that U type slot is connected to It withstands on the clamping block 124 of the 113 center third interfacing part 123 of longitudinal support of 10 main body rack 11 of slide unit trolley and persistently, The alignment sensor 4855 for pulling mechanism later senses whether clamping block 124 is clamped.If contactless card is caught, lock is put down at this time The handle 54535 of tight unit 545.The motor 482 of offline power buggy carries out first time drag operation, upper offline power in startup Trolley is moved along direction in the motor slide rails 522 outwardly slot of transition bracket 43, so as to drive slide unit trolley 10 in the slide unit that comes in and goes out It is slided on guide rail 542 to the outer transition guide 46 on outer transition bracket 43.Power buggy sense in outer 43 slot of transition bracket It is offline in closing when answering the device 91 to detect the sensing detection block 484C on the outside of first, second sliding block part of offline power buggy The motor 482 of power buggy, and the cylinder 4851 of the dragging mechanism 485 of upper offline power buggy declines, so that pulling The U type slot of mechanism 485 is detached from the clamping block 124 of the third interfacing part 123 of 10 center of slide unit trolley.Interior transition bracket 42 The cylinder 4233 of upper rail shedding mechanism 423, which pushes to close, can be opened and closed guide rail group 47, and be caused by 333 rotary slider 332 of cylinder Guide rail 334 is turned to connect guide rail group 47 can be opened and closed as straight line with the outer transition guide 46 on outer transition bracket 43.Later, on Offline power buggy is back to detent mechanism 52 on 5414 side of П types push rod, by the clamping geosynclinal block of upper offline power buggy 48521 clamping blocks 124 being further clamped on the second interfacing part 122 on slide unit trolley 10 carry out the second drag operation, and open The motor of dynamic offline power buggy 546, slide unit trolley 10 is further pushed to above interior transition bracket, so far completes slide unit Trolley 10 is reached the standard grade supreme offline slide unit unit 40.Then it is detached from the dragging mechanism of upper offline power buggy 546 and slide unit trolley 10 The connection to connected components 12.

(4) slide unit trolley 10 is located on interior transition bracket at this time, the gas for the shedding mechanism 423 that got on the right track by interior transition bracket 42 The unlatching of cylinder 4233 can be opened and closed guide rail group 47, and by 332 to 90 ° of 333 rotary slider of cylinder so that steering guide rail 334 will be upper offline Slide unit guide rail 44 is connected with the interior transition guide 45 of upper short 422 upper surface of vertical pole as straight line.It is upper in the straight-line groove 401 that can be connected The clamping geosynclinal block 4852 that offline power buggy 48 pulls mechanism 485 is promoted by cylinder 4851 so that U type slot is connected to cunning The clamping block 124 of the side third interfacing part 123 of 10 longitudinal support 113 of platform trolley.At this point, the steering on corner slide unit stent 31 Upper offline slide unit guide rail 44 also with the corner guide rail 32 of upper short 315 upper surface of vertical pole is adjusted and connected as straight line by mechanism 33.With Upper offline power buggy 48 drives slide unit trolley 10 to be slided on upper offline slide unit guide rail 44 to corner slide unit unit 30 afterwards.

(5) when the slide unit trolley 10 equipped with A vehicle welding fixtures, by turning for the steering mechanism 33 on corner slide unit stent 31 Direction guiding rail 334 is rotated by 90 °, with the traversing power buggy 24 in traversing 20 slot of slide unit stent of reason drive slide unit trolley 10 slide to Each welding position.And each slide unit trolley 10 is fixed by detent mechanism 92 by the line outside traversing 20 slot of slide unit stent, is ventilated Work is detected with vehicle.

In addition, white body welding production line is also embodied in arbitrarily cutting to required welding vehicle with the flexibility of flexible slide unit It changes and replaces with.Due to being limited by space, this equipment is designed by online four kinds of vehicles (A vehicles, B vehicles, C vehicles and D Vehicle) arbitrarily switching, such as increase vehicle need first a kind of offline vehicle welding fixture reach the standard grade again new welding fixture.Vehicle switching is former Reason description：

1st, when cache bit does not have vehicle waiting, upper offline power buggy 48 and traversing power buggy 24 can be directly by institutes The vehicle welded A is needed to drag to welding position to be welded.

If the 2nd, be located at cache bit there are many vehicle on flexible slide unit, and vehicle to be welded can not directly slide into weldering It when connecing, then needs other vehicles being transferred to other cache locations, the vehicle to need to weld opens channel.

Concrete principle describe as shown in fig. 7, welding position I, wait for position II, wait for position III have vehicle A, vehicle B and vehicle C respectively, And it needs to weld vehicle D.Then need：Vehicle A slides into cache bit IV；Then, vehicle B slides into V position, and vehicle C slides into VI position, Upper offline power buggy 48 and traversing power buggy 24 connect vehicle D and welding position I are dragged to be welded.
