The closure screw 3 of the bounce situation adjustment different parts of part second end face 10, makes bounce≤public affairs of final part second end face 10
Difference B, 0.008mm≤tolerance value B≤0.012mm in the utility model；Then Anti-inclining screw 6 is screwed.
So far, which completes.
The design principle of the utility model:
The utility model is that second end face during smart car is avoided to be in cantilever position, the Double End floating positioning support seat
While first end face positioning, support is also provided at second end face.Consider the second end face of processed each part
There is nuance with the difference in height of first end face, common Double End positioning fixture can only actually have an end face sturdy, separately
One end face loss of function, and the difference of the second end face of each part and first end face difference in height, which, which floats, positions
Support base guarantees the same of first end face firm position in such a way that compressed spring drives cylindrical bar to withstand part second end face
When, second end face is also in close contact with fixture always.The ontology adapted of Double End floating positioning support seat and existing fixture, adapted
Ontology to be used to support the position of Double End floating positioning support seat be non-critical sides, rough surface so that Double End float it is fixed
The first supporting surface bounce of position support base is not easy to guarantee.To solve this problem, levelling bolt is contacted with ontology non-critical sides
End can be adjusted by the thread height as spherical shape.When clamping, it can be adjusted by the thread Double End floating positioning support seat
The first supporting surface bounce be adjusted to claimed range.
The foregoing is merely the preferable case study on implementation of the utility model, are not intended to limit the utility model, it is all
Within the spirit and principles of the utility model, it is practical new to should be included in this for any modification, equivalent replacement, improvement and so on
Within the protection scope of type.
