Cylinder 5-6 stretches out, and master positioning pin 5-1-1 is pushed to stretch out, until an end face S5-1-1-2 and telescopic pin cylinder of master positioning pin 5-1-1
Stop after a First terrace 5-4-2 defining flange or first step face contact of erection support 5-4, the depth of cavity H5-4-1
The extension elongation of degree control master positioning pin 5-1-1.The 5-5 pair pin retention mechanisms course of work: telescopic pin pusher cylinder is stretched out, and is pushed
Secondary positioning pin 5-5-1 stretches out, and waist hole 5-5-2-1 limits the direction of guiding deviation M5-5-1-2, makes secondary positioning pin 5-5-1 diamond shaped
Maximum direction always towards Y-direction, until the 6th positioning surface 5-5-1-3 and telescopic pin cylinder of secondary positioning pin 5-5-1 are installed
Stop after the First terrace 5-4-2 contact of support 5-4, the stretching of the deep-controlled secondary positioning pin 5-5-1 of the first cavity 5-4-1
Length.
(2) it is put into workpiece subframe lower plate 1-2: the lower plate location hole 1-2-1 of subframe lower plate 1-2 is directed at master positioning pin
5-1-1 and secondary positioning pin 5-5-1, is put into workpiece subframe lower plate 1-2, until lower plate positioning surface 1-2-2 and master positioning pin 5-1-1
The first positioning surface 5-1-1-3 and secondary positioning pin 5-5-1 the 4th positioning surface 5-5-1-7 contact；By increasing and decreasing adjusting gasket 5-8
Contact I 5-2 of locating piece and II end face 3-5 of locating piece with workpiece surface.
(3) two are started switch, the second positioning device 2 and third positioning device 3 work: I 2-10 of cylinder returns to cylinder row
Way limit position stops, and II 3-3 of cylinder stretches out after the end face G3-4-2 of sliding block mounting bracket B3-4 is contacted with limited block 2-6
Stop, so that the cylinder ball 2-13 of I 3-2 of link block A II 2-2 and link block B is pushed down the inner surface of subframe lower plate 1-2, by work
Part clamps.
(4) it is put into workpiece subframe upper plate 1-1: the upper plate location hole 1-1-1 of subframe upper plate 1-1 is directed at master positioning pin
5-1-1 and secondary positioning pin 5-5-1, is put into workpiece subframe upper plate 1-1.Start switch three, clamping device 6 is by subframe upper plate 1-

Plate 1-2 (note: only the second cylinder 5-1-1-4 is exited, and is not that entire positioning pin exits), the 4th cylinder 5-1-1-5 is moved back completely
Subframe upper plate 1-1 out.Only have the lower plate location hole 1-2-1 of subframe lower plate 1-2 still in the second cylinder 5-1-1-4 at this time and
Between 4th cylinder 5-1-1-5, the pin section diameter between this is smaller than lower plate location hole 1-2-1 diameter, and part is in loosening state.
Secondary pin retention mechanisms 5-5: telescopic pin pusher cylinder is retracted, and pushes pair positioning pin 5-5-1 to retract, until secondary positioning pin 5-5-1's
6th cylinder 5-5-1-4 exits subframe lower plate 1-2 completely, and (note: only the 6th cylinder 5-5-1-4 is exited, and is not entire fixed
Position pin exits), the 7th cylinder 5-5-1-6 exits subframe upper plate 1-1 completely.Only have the lower plate of subframe lower plate 1-2 fixed at this time
Still between the 6th cylinder 5-5-1-4 and the 7th cylinder 5-5-1-6, the pin diameter between this positions position hole 1-2-1 than lower plate
Hole 1-2-1 diameter is small, and part is in loosening state.Take out workpiece.Since apparatus of the present invention have automatic pin function, effectively solve
The problem of workpiece thermal deformation generates stress when welding, blocks positioning pin, leads to artificial difficult pickup.
In design, when secondary positioning pin 5-5-1 is retracted, it is ensured that deviation M5-5-1-2 is always in waist hole 5-5-2-1 for guiding
Interior, preventing cylinder axis from rotating leads to be oriented to deviation M5-5-1-2 and waist hole 5-5-2-1 dislocation, pair positioning pin 5-5- when next time starts
1 stuck phenomenon.
