It is dangerous larger, and it is not suitable for repeatedly upset, it is impossible to realize structural member welding sequence optimization；
2nd, structural member welding process is with level or the welding welding of edge-on position, it is impossible to conjugated, position while welding is the straight angle
Welding position is put, it is impossible to realize that optimum ship type welding position puts welding, welds internal soundness to structural member and appearance forming quality causes one
Fixed impact.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided a kind of crawler crane large-sized structural parts
Positioner, solve prior art in crawler crane do not possess positioner cause crawler crane large-sized structural parts without
Method carries out deflection welding, affects the technical problem of welding quality.
To solve above-mentioned technical problem, the technical scheme adopted by this utility model is：A kind of large-scale knot of crawler crane
Member Welding positioner, including what is be oppositely arranged：Displacement headstock and positioner tailstock, the displacement headstock and displacement tail
Seat includes respective respectively：Jacking system, upset system and for treating the clamping mechanism positioned by welding structural element；It is described
Upset system is connected with jacking system, and the clamping mechanism is connected with upset system；Structural member to be welded is fixed by clamping mechanism
In upset system, jacking system drives upset system to rise to preset height position and carries out upset displacement.
Further, the upset system includes：General jig frame and the upset driving machine for driving general jig frame to overturn
Structure.
Further, the clamping mechanism is included on general jig frame：Axial direction positioning device, laterally and tightly propped device and
Hold down gag.
Further, the shifting that the bottom of the positioner tailstock is additionally provided with guide rail and drives positioner tailstock to move along guide rail
Motivation structure, the guide rail extend laying from positioner tailstock to displacement headstock.
Further, the jacking system is configured with altimeter coder.
Further, the angled encoder of the upset system configuration.
Compared with prior art, the beneficial effect reached by this utility model is：1st, it is applied to crawler belt there is provided one kind to rise
The large-sized structural parts positioner of heavy-duty machine, during the large-sized structural parts welding process such as track beam, vehicle frame and turntable can be realized
Overturn displacement, it is to avoid using driving or whipline upset operation, can effectively reduce operation danger and hand labor intensity；2、
Positioner tailstock is provided with travel mechanism, disclosure satisfy that the upset displacement of different size large-sized structural parts, effectively reduces upset work
Dress cost input；3rd, large-sized structural parts upset displacement can be easily realized, weld seam is put in ship type welding position, can be greatly improved big
Type welds welding quality.
Description of the drawings

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.Following examples are only used for clearly illustrating this
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
As shown in figure 1, crawler crane large-sized structural parts positioner, including opposed setting：Displacement headstock 1
With positioner tailstock 2.
Displacement headstock 1 and positioner tailstock 2 are respectively equipped with respective：Jacking system 3, upset system 4 and for treating
The clamping mechanism positioned by welding structural element.Upset system 4 is connected with jacking system 3, and clamping mechanism is connected with upset system 4
Connect.Wherein, jacking system 3 is configured with altimeter coder, realizes the synchronization lifting of two jacking systems 3；Upset system 4 is configured with angle
Degree encoder, realizes the synchronous upset of two upset systems 4.
Upset system 4 includes：The general jig frame 4a and turnover driving mechanism 4b for driving general jig frame 4a to overturn.It is general
Moulding bed 4a is provided with screwed hole, keyway and T-slot, and the clamping mechanism of supplementary module, realizes track beam, vehicle frame, turntable etc.
The Set and Positioning of different types of large-sized structural parts, is that later stage automatic welding lays the foundation.
Clamping mechanism is included on general jig frame 4a：Axial direction positioning device 5a, laterally and tightly propped device 5b and compression dress
Put 5c.As shown in figure 1, hold down gag 5c includes：Support and the pressing plate on support, but in actual use, not
It is limited to the structure, it would however also be possible to employ bolt coordinates pressing plate to realize the compression positioning of large-sized structural parts.
In order to meet the demand of the large-sized structural parts of different length size, the bottom of positioner tailstock 2 is additionally provided with 6 He of guide rail
Drive positioner tailstock 2 along the travel mechanism 7 of the movement of guide rail 6, guide rail 6 extends paving from positioner tailstock 2 to displacement headstock 1
