Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.Should be appreciated that this place
The specific embodiment described, only in order to explain this utility model, is not used to limit this utility model.
As Figure 1-5, small-sized gantry lathe special coupler of the present utility model, including intermediate 1, it includes cylinder
11 and be integrally formed in the adpting flange 12 at cylinder two ends, described adpting flange 12 is staggeredly equipped with multiple perforation 13 He
Screw cap hole 14, the via of the adpting flange of both sides and screw cap hole confronting coaxial arrange, the via on the most each adpting flange and
Correspondence before and after screw cap hole on another adpting flange, vice versa.
Two groups of metal plate springs groups 2, it passes through the first connecting bolt 3 respectively and described adpting flange is fixed and is connected, institute
The head of the first connecting bolt 3 stated is positioned at adpting flange medial surface, i.e. the head of the first described connecting bolt passes spiral shell
It is positioned in inside perforation after cap aperture；
Two adapter sleeves 4 fixing to be connected by the second connecting bolt with described metal plate springs group accordingly, described
The nut of the second connecting bolt 5 correspondence be placed in described screw cap hole 14.
Wherein, described metal plate springs group 2 is formed by fixedly connecting by the flat spring of multi-disc stainless steel, described gold
