For reaching above-mentioned purpose, the orthopedic equipment of truss framed leg main chord tube of the present invention, including the orthopedic work of rigidity
Station, on the orthopedic workbench of described rigidity, interval arranges plural gate-type support body；On described gate-type support body
Suspension has the jack arranging pressure transducer.Orthopedic orthopedic with glacing flatness direction for main chord tube camber direction
Two kinds of situations are respectively provided with to change mode: the orthopedic fixing seat of camber being positioned on the described orthopedic workbench of rigidity
Assembly and the orthopedic fixing holder assembly of glacing flatness, and it is positioned at the camber orthopedic pressure head peace of described jack lower end
The orthopedic pressure head of straight degree.
The orthopedic fixing holder assembly of the most above-mentioned camber and the orthopedic fixing holder assembly of glacing flatness, the orthopedic pressure head of camber and
The orthopedic pressure head of glacing flatness, can realize the form of said function to arrange different structure as required, and the present invention carries
Supply following preferred version:
The orthopedic fixing holder assembly of described camber includes the fixation structure that both sides, top are arranged, described fixed structure
It is clamped in two side positions of main chord tube side tooth bar by wood tooth in the middle part of body；The orthopedic fixing holder assembly of described camber
Also include being positioned at below main chord tube tooth bar and the protection cushion block coordinating profile of tooth is set.
The orthopedic fixing holder assembly of described glacing flatness includes that both sides, top are propped up and peaks at main chord tube both sides tooth bar lower surface
Supporting structure；
The orthopedic pressure head of described camber is inverted U structure, and mold pressing position, middle part is positioned at main chord tube tooth bar and is provided above
Coordinate the protection cushion block of profile of tooth.
The cross section of the orthopedic pressure head of described glacing flatness is inverted U, and both sides leg, for molding position, is pressed on main chord tube
Both sides tooth bar upper surface.
Orthopedic Working table structure in the present invention is reliable, can meet truss framed leg main chord tube the most mostly orthopedic
Need, it is possible to effectively complete the orthopedic demand of spud leg main chord tube.The present invention has following several big advantage:
1, whole process belongs to mechanical orthopedic, does not affect the mechanical property of main chord tube；
2, process control and be easy to detection monitoring, risk is low, safety is high.
3, the orthotic procedure time is short, efficiency is high, saves manpower；
4, a whole set of frock can reuse for a long time, and cost is low with maintenance cost；
5, the dependence to large pressing machine can be broken away from, more convenient.
