Description

The cubing of longhole inner circle cone end diameter
Technical field
The utility model relates to a kind of cubing of longhole inner circle cone end diameter.
Background technology
Fig. 1 is a tubing sub, and in its threaded hole, having a cone, its end diameter is 5mm, and tapering is 40 degree, and cone small end is 8mm apart from the distance in aperture, and large end is 11mm apart from the distance in aperture.In order to guarantee connection and the sealing property of tubing sub, need measure the end diameter of cone.
Circular cone ring gauge is the crucial testing tool in machine tool chief axis process.Along with the further raising of machine tool capability, precision and speed, the manufacture of taper ring-ga(u)ge is had higher requirement.Utilize circular cone ring gauge to be difficult to accurately measure cone end diameter.
Summary of the invention
For above-mentioned technical matters, fundamental purpose of the present utility model is for providing a kind of cubing that can accurately measure longhole inner circle cone end diameter.
The cubing of longhole inner circle cone end diameter, comprise pedestal, detection bodies, T-shaped measuring staff, spring and trip bolt, one end of pedestal is provided with stepped hole, this stepped hole is axial arranged along pedestal, the other end of pedestal is provided with threaded hole, this threaded hole is communicated with the large aperture end of stepped hole, one end of detection bodies is threaded with the threaded hole of pedestal, one end of detection bodies is provided with straight hole, the other end of detection bodies is provided with the taper hole communicating with straight hole, the top bar hole, large footpath in hole of straight hole in detection bodies and pedestal is communicated with, the bigger diameter end of T-shaped measuring staff is positioned at the hole, large footpath of stepped hole, the miner diameter end of T-shaped measuring staff extend in the straight hole of detection bodies and is slidably matched with straight hole, described spring is assemblied in the hole, large footpath of stepped hole, one end of spring is spacing by the step surface of stepped hole, the other end of spring is spacing by the bigger diameter end of T-shaped measuring staff, the outside wall surface of described pedestal is provided with radial hole, the little radial communication of this radial hole and stepped hole, trip bolt is threadedly connected in radial hole.
Further, also comprise a handle, one end of this handle is fixed in the outside wall surface of pedestal.
Further, described handle is comprised of flat segments and segmental arc, and one end of flat segments is connected with pedestal, and the other end of flat segments is connected with segmental arc.
Adopt such scheme, before using the utility model to detect cone, by the end diameter of circular cone, made a circular cone calibrated bolck, as proofreading and correct.Timing, dial gauge is inserted in the diameter holes of stepped hole, and with trip bolt, dial gauge is carried out fasteningly, the taper hole in calibrated bolck and detection bodies is closely cooperated, now T-shaped measuring staff up moves and drives the measuring staff of dial gauge to move, and the pointer of dial gauge is rotated.Spring is compressed, now by the pointer zeroing of dial gauge.Reading on dial gauge is the diameter of cone small end.Take out calibrated bolck, spring is no longer stressed, restorable, T-shaped measuring staff is pushed up to original position simultaneously.While detecting many workpiece, employing, with upper type, provides cone end diameter tolerance, and converses the cone length tolerance that the tolerance due to end diameter forms, like this can be directly by the variation of dial gauge reading, show that the end diameter of cone size is whether in margin tolerance.
