The utility model conical dowel pin is designed to floating structure, promptly on the end cap inner screw, be with spring, adapting to the variation of the pore size of need measuring, the annular cones face of conical dowel pin fits with longeron face perpendicular to tested place during measurement, prevents the hole center reference generation deviation of measuring.
The utility model is than the precision height that adopts vernier caliper
Description of drawings
Fig. 1 is the utility model general assembly drawing.
Fig. 2 is the utility model schematic top plan view.
Fig. 3 is the utility model user mode figure.
Embodiment
As Fig. 1, Fig. 2: the utility model measurer body 4 links into an integrated entity with sliding guide 9; Pilot hole 4.1 is arranged on the measurer body 4, and conical dowel pin 5 adopts transition fit with pilot hole 4.1, and end cap 2 is arranged on the measurer body 4, and the top of conical dowel pin 5 is minor radius screw rods 5.1, and screw rod 5.1 passes the hole and adjusting nut nail 1 coupling of end cap 2; On end cap 2 inner screws 5.1, be with spring 3.
The slide block 7 of measurement is arranged on the sliding guide 9, measure slide block 7 bottoms and connect measurement and positioning piece 6, measuring has range finding digital display module 11 on the slide block 7.
On the sliding guide 9, measure the holding screw 8.1 that there is tightening slide block 8 on slide block 7 right sides and matches.
Conical dowel pin is as special measuring tool centerline hole benchmark, and the automatic pilot hole center of circle overlaps with the conical dowel pin central axis; The measurement and positioning face 6.1 of measurement and positioning piece 6 is as the another one benchmark of measuring, the i.e. tested aerofoil of longeron or the position of the outside of belly.
Conical dowel pin of the present utility model plays the center of circle positioning action to measured hole, and conical dowel pin can adopt any adjustable mode that is decided to be.Be designed to floating structure, the purpose that promptly is with spring 3 on end cap 2 inner screws 5.1 is the variation that adapts to the pore size of measured hole, during measurement the annular cones face of conical dowel pin with fit more balancedly perpendicular to the longeron face at measured hole place, prevent to measure with the center, hole deviation take place.
It is the cylinder 5.2 of R/2 that the vertex of a cone of conical dowel pin 5 has a radius; About R/2=2MM, cylinder and circular cone concentric.There is the measurement and positioning face 6.1 than left side face at the zero point 7.1 extension elongation H=R/2 that measure slide block 7 in the left side of measurement and positioning piece 6.Be convenient to check for zero.
In the school zero the time, the face at zero point of measuring slide block 7 7.1 is leaned against on cylinder 5.2 sidewalls, the digital display module of will finding range 11 readings are set to zero and are got final product.
As Fig. 3: when measuring, conical dowel pin 5 is aimed at the hole 10.1 of tested vehicle frame U type longeron 10, regulate nut nail 1 and makes the tapering point of conical dowel pin 5 steadily fall into hole 10.1 securely, the center of circle in hole 10.1 is dropped in the axle center of conical dowel pin 5; Then, promote to measure slide block 7, the measurement and positioning face 6.1 of measurement and positioning piece 6 is attached on the tested surface 10.2 of tested vehicle frame U type longeron 10, tightening slide block 8 is close to measures slide block 7, tighten holding screw 8.1, will measure the locking position of the measurement and positioning face 6.1 of slide block 7 and measurement and positioning piece 6.The reading of the digital display module 11 of finding range this moment is exactly the distance between hole 10.1 and the tested surface 10.2.
Core of the present utility model be adopt a conical dowel pin as the measurement and positioning piece of the location, the center of circle of measured hole and relative slip with it as another measurement and positioning face, decide the distance on longeron hole and limit.Therefore, no matter how how the structure of conical dowel pin assembly part change with measurement and positioning piece part, and every employing one point location and the measurement and positioning face of relative slip combine and find range, and all belong to protection domain of the present utility model.
