Further, each fixture includes at least four locating pieces, and four locating pieces are arranged symmetrically.
Further, the headstock is slidably connected with the guide rail.
Further, the banking stop is in be symmetrically provided with two.
Further, the rocking arm is two, and two rocking arms are symmetrical arranged, and two rocking arms are with the pedestal
The upper end of hinge connection, each rocking arm is provided with idler wheel.
The present invention has the advantages that compared with the existing technology：Anti-deformation welding fixture disclosed by the invention, including
Babinet, pedestal, rocking arm, headstock, guide rail, positioning device, babinet are fixedly connected with pedestal, are respectively set on babinet and headstock
There is positioning device, and two positioning devices, in same level, two symmetrically arranged rocking arms are connect with base hinge, can be used
In holding up soldered workpiece, prevents workpiece from sliding or deforming in the welding process, cunning is provided between pedestal and headstock
Rail, headstock are slidably connected with sliding rail, can according to the distance between the length adjustment headstock of workpiece and babinet, so set,
The stability between two positioning device, rocking arm upper end are provided with idler wheel, can effectively avoid certifiable workpiece in the welding process
Workpiece is deformed during lifting, and so as to effectively improve welding quality, avoids the areas weld seam Ji Jinfeng in welding process
The thermal contraction of metal is because of phenomena such as elastoplasticity stretcher strain is occurred by the constraint of the colder part in both sides.
The additional aspect and advantage of the present invention will be set forth in part in the description, and will partly become from the following description
It obtains obviously, or recognized by the practice of invention.

Specific implementation mode
Below with reference to attached drawing, the present invention is described in detail.
In conjunction with shown in Fig. 1, anti-deformation welding fixture disclosed in the present embodiment, including babinet 1, pedestal 2, rocking arm 3, headstock
4, guide rail 5, positioning device 6, it is preferable that babinet 1 is fixedly connected with pedestal 2, and rocking arm 3 is connected on pedestal 2, and the setting of guide rail 5 exists
Between headstock 4 and pedestal 2, positioning device 6 is separately positioned on babinet 1 and headstock 4, and manufacturing cost is cheap, is more suitable for pushing away
Wide application.
Each positioning device 6 includes handwheel 7, axis 8, static housing 9, fixture 10, specifically, on babinet 1 and headstock 4
It is provided with multiple positioning devices 6, it is preferable that the quantity of positioning device 6 disclosed in the present embodiment is two, two positioning devices 6
It is corresponding in being symmetrically arranged at babinet 1 and headstock 4, each positioning device 6 include handwheel 7, axis 8, static housing 9,
Fixture 10, control handwheel 7 can adjust the rotation angle of static housing 9 by the effect of axis 8, and then can be true according to the shape of workpiece
