Description
Technical field
The utility model belongs to Aircraft Tools manufacturing technology, relates to a kind of cursor seat detected.
Background technology
The cursor seat of original detection Aircraft Tools pilot hole exists inserts after in pilot hole, executes external force be fixed in dress pilot hole by operator with hand.Because the internal diameter size of cursor seat locating shaft outside dimension and Aircraft Tools pilot hole exists foozle, therefore easily occur that cursor seat locating shaft rocks in Aircraft Tools pilot hole, make the defect that accuracy of detection declines.
Summary of the invention
The object of the invention is: a kind of cursor seat that can be fastened in detection and location hole and energy accurate detection and location axially bored line direction coordinate is provided.
Technical scheme of the present invention is: one can fastening cursor seat, comprise positioning seat 1 and set nut 2, positioning seat 1 and set nut 2 are screwed together, positioning seat 1 comprises half circular shaft 3, locating shaft 4, screw rod 5 and disk 6, the side plane of half circular shaft 3 has the first through hole 7 and the second through hole 9, the side plane of half circular shaft 3 perpendicular to disk 6 upper surface and be positioned at the axle center of locating shaft 4, the upper surface of disk 6 is parallel with lower surface, locating shaft 4 is coaxial with screw rod 5, the axial line of locating shaft 4 is perpendicular to the lower surface of disk 6, the centerline hole of the first through hole 7 and the second through hole 9 passes through the axial line of locating shaft 4, set nut 2 is stepped cylindrical body, and there is a through threaded hole 8 at the center of set nut 2.The external thread of the dimension of inner screw thread of threaded hole 8 and the screw rod 5 of positioning seat 1 is measure-alike.The maximum periphery of set nut 2 is annular knurl face.
The utility model has the advantages that: can accurate two ends, fixed test pilot hole axes direction central point three-dimensional coordinate, improve accuracy of detection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
