Pointer fixing seat, the pointer cap of pointer is mounted in pointer fixing seat, two guiding above two lower linear bearings
There are two upper linear bearing, probe card is mounted on two upper linear bearings for installation on column, and pointer is equipped in the middle part of probe card
Axis, needle pivot are staged needle pivot, and the open tubular column of needle pivot and pointer is coaxially arranged, is equipped on the vertical plate above probe card
The pressure head end of active grab, active grab acts against on probe card.
The beneficial effects of the invention are as follows：Apparatus of the present invention detect inverted needle pivot, pointer also inverted arrangement, and
Detection process is implemented using mechanical mechanism, excludes manual operation error, guarantees the critical sizes such as the depth of parallelism and verticality, detection knot
Fruit is accurate.1, whether can be biased with intuitive judgment needle pivot.It 2, can be with intuitive judgment needle pivot biased direction.3, can about sentence
Severed finger needle shaft number of offsets.4, pointer can be rotated with 360 °, judge needle pivot bias state.5, needle pivot and pointer be may determine that
Whether cap is vertical.6, it can quickly detect, apparatus of the present invention detect the offset direction of pointer, about numerical value etc., and detection type is more.
Present invention efficiently solves traditional detection needle pivots using being manually placed on small optical axis such as straight optical axis, is detected using clearance gauge
Non-key position obtains needle pivot key position size by theory reckoning, there are testing result is fuzzy, inaccuracy, error compared with
Big problem.
