Specifically, in the present embodiment, clamping seats 125 are equipped on each longeron clamping element 123.The clamping of the present embodiment
Seat 125 is mounted on slide unit 15, and two clamping seats 125 being oppositely arranged can be realized relatively close or separate on slide unit 15.At this
In embodiment, third actuator 126 is fixed on clamping seats 125, which has along the width side of rack 11
To flexible output shaft.In longeron clamping element 123, wherein a longeron gripping block 124 is fixed at third actuator 126
On output shaft, another longeron gripping block 124 is fixed on clamping seats 125, and positioned at the inside of third actuator 126.
When the output shaft of third actuator 126 stretches out, the longeron gripping block 124 on 126 output shaft of third actuator
It can be close to the lateral surface of 21 web of longeron, and push longeron 21 towards another front longitudinal beam gripping block in 11 width direction of rack
124 is close, so that another longeron gripping block 124 is close to the medial surface of 21 web of longeron, to make two longeron gripping blocks 124 divide
It is not connected to the both sides of longeron 21, it is ensured that longeron 21 is fixedly clamped.
In the present embodiment, spacing is equipped between the lower face and the upper surface of clamping seats 125 of two longeron gripping blocks 124,
For housing the lower wing plate of longeron 21.
Further, it is connected by forward lead screw between the clamping seats 125 for two longeron clamping elements 123 being oppositely arranged,
Under motor driving, two longeron clamping elements 123 can synchronize relatively close or separate.
In X to after the completion of positioning, the longeron gripping block 124 of longeron clamping element 123 fixes to clamp vertical two longerons 21 of vehicle frame
Beam 21 drives two longeron clamping elements 123 to synchronize separate, the distance between two longerons 21 is made to be more than the length of crossbeam 25 in Rear frame 2
Degree.It is indicated at this time by the positioning being arranged on 21 web of longeron in advance, the artificial location and installation for carrying out interior crossbeam 25.Rear frame
After crossbeam 25 installs in 2, then to drive two longeron clamping elements 123 to synchronize close, so that the medial surface of two longerons 21 supports respectively
The both ends of interior crossbeam 25 are connected on, to realize positioning of the longeron 21 in Y-direction.
In addition, refering to fig. 1, the assembled tooling 1 of the present embodiment further includes material fetching mechanism 16.The material fetching mechanism 16 includes two groups
Roller station, two groups of roller stations are arranged in the both sides of rack 11.Every group of roller station includes between multiple 11 length directions along rack
Every the carrying roller 161 of arrangement, each carrying roller 161 can be rotated around the axis of its own, axis direction and the rack 11 of carrying roller 161
Length direction is vertical, and the carrying roller 161 is adjustable with respect to the height of rack 11.
Longeron 21 to be assembled can be delivered in rack 11 by the rotation of carrying roller 161, wait for that longeron 21 drops down onto on clamping seats 125
When, carrying roller 161 declines relative to rack 11, is interfered with longeron 21 to avoid during Rear frame 2 is assembled.Wait for Rear frame
After the completion of 2 integral assemblings, carrying roller 161 rises to concordant with the upper surface of clamping seats 125 again, and the rotation of carrying roller 161 at this time can will half
Trailer Rear frame 2 is delivered to subsequent work platform position.
When semitrailer Rear frame 2 assembled using the assembled tooling 1 of the present embodiment, specific assembly process is as follows：
Longeron 21 is delivered in rack 11 by carrying roller 161, so that longeron 21 is fallen on clamping seats 125, at this time carrying roller
161 opposite racks 11 decline；It drives the two longeron gripping blocks 124 relatively close to clamp longeron 21, then drives two to be oppositely arranged
Longeron clamping element 123 is relatively close, so that the spacing between two longerons 21 reaches the first setting value, is driving two longeron gripping blocks
124 are relatively distant to unclamp longeron 21.
22 feeding of back end beam, and it is made to drop down onto on positioning seat 132, drive two opposite positioning seats 132 to synchronize close, with
The first positioning surface is set to be connected to the end of back end beam 22, or the lateral surface for making the second positioning surface be connected to 22 lock of back end beam, it is real
Positioning of the existing back end beam 22 in Y-direction；Back end beam 22 is fixed to clamp by back end beam clamping element 131 again, drives back end beam localization machine
In the longitudinal direction close to stopping unit 121, back end beam 22 moves to push longeron 21 structure 13, makes the end of longeron 21
Be connected on stopping unit 121, with realize longeron 21 X to positioning；For longeron 21 after the completion of X is positioned upwards, back end beam is fixed
Position mechanism 13 is far from stopping unit 121.
So that longeron gripping block 124 is fixedly clamped longeron 21, driving longeron clamping element 123 so that between two longerons 21 away from
From the second setting value is reached, the interior crossbeam 25 of installation Rear frame 2 is positioned manually.Longeron clamping element 123 is driven again so that two longerons
The distance between 21 reach third setting value, and the medial surface of two longerons 21 is connected to the both ends of interior crossbeam 25 respectively at this time, to
Realize positioning of the longeron 21 in Y-direction.For the Rear frame 2 with tapered end, also need manually to wear tapered end crossbeam 24 on longeron 21.
Drive back end beam detent mechanism 13 on 11 length direction of rack close to stopping unit 121 again so that the side of back end beam 22 with
The end of longeron 21 fits, to realize back end beam 22 X to positioning.
23 feeding of tapered end module makes roof hole and 144 location fit of positioning pin, drives the output shaft of the first actuator 147
