Description
Technical field
A kind of cubing is the utility model is related to, straight hole is relative to taper hole axis on specifically a kind of detection measured workpiece
The cubing of axiality.
Background technology
In the manufacture field of auto parts, some special testing requirements are frequently encountered, wherein, clutch starter housing
In i.e. require detection straight hole relative to taper hole axis axiality.With three coordinate measurements, each is required for clamping, and efficiency is very
It is low, it is therefore desirable to which that a kind of very simple and convenient cubing used detects to realize.
The content of the invention
The purpose of this utility model is to provide for a kind of coaxiality check fixture, can detect on measured workpiece straight hole relative to cone
The axiality of axially bored line.
To achieve these goals, the technical solution of the utility model is：A kind of coaxiality check fixture, by hexagonal flange spiral shell
Female, measurement column and detection set are formed, and hexagonal flange nut coordinates with threaded post；Detection set coordinates with detection post.
Measurement column includes threaded post, cone, cylinder, detection post and the part of guide cone five；Threaded post is in cone
Left side, cylinder is on the right side of cone, and detection post is on the right side of cylinder, and guide cone is on the right side of detection post.
The diameter of bore of detection set is Φ A, and tolerance is（0 ,+0.003）mm；Male cone (strobilus masculinus) relative to endoporus central axis jump
Move as 0.005mm.
A diameter of Φ B of detection post, and Φ B=（ΦA-0.3+0.036）Mm, tolerance are（0, -0.008）mm；Cone
Taper is C, and tolerance is ± 3 '；Post is detected relative to cone（22）The axiality of central axis is 0.005mm；The cone of guide cone
Spend for 25 degree.
During actual use, the taper hole of conical sections and measured workpiece on measurement column coordinates, and hexagonal flange nut is with surveying
The threaded post measured on post coordinates, and measurement column is fixed on workpiece；The endoporus and detection post for detecting set coordinate, the cone for covering detection
Face contacts with the aperture in Φ E holes on workpiece, observes whether whole circular conical surface uniformly contact with the aperture in Φ E holes, if uniformly
The tested axiality of contact explanation is qualified, otherwise unqualified.
The utility model can detect the axiality of straight hole on measured workpiece relative to taper hole axis in use, meanwhile,
Have the characteristics that simple in construction, accuracy of detection is high, performance safety is stable, low manufacture cost.

Embodiment
Below in conjunction with the accompanying drawings explanation according to the utility model proposes specific device details and working condition.
The device is made up of hexagonal flange nut 1, measurement column 2 and detection set 3, hexagonal flange nut 1 and threaded post
21 coordinate；Detection set 3 coordinates with detection post 24.
Measurement column 2 includes threaded post 21, cone 22, cylinder 23, detection post 24 and the part of guide cone 25 5；Screw thread
Post 21 is in the left side of cone 22, and cylinder 23 is on the right side of cone 22, and detection post 24 is in the right side of cylinder 23, guide cone
25 on the right side of detection post 24.
The diameter of bore of detection set 3 is Φ A, and tolerance is（0 ,+0.003）mm；Male cone (strobilus masculinus) is relative to endoporus central axis
Beat for 0.005mm.
A diameter of Φ B of detection post 24, and Φ B=（ΦA-0.3+0.036）Mm, tolerance are（0, -0.008）mm；Cone
22 taper is C, and tolerance is ± 3 '；It is 0.005mm that post 24, which is detected, relative to the axiality of the central axis of cone 22；Guide cone
25 taper is 25 degree.
In the course of the work, the taper hole of the part of cone 22 on measurement column 2 and measured workpiece coordinates, hexagonal flange nut
1 coordinates with the threaded post 21 on measurement column 2, and measurement column 2 is fixed on workpiece；The endoporus of detection set 3 coordinates with detection post 24,
The conical surface of detection set 3 is contacted with the aperture in Φ E holes on workpiece, whether equal with the aperture in Φ E holes observe whole circular conical surface
Even contact, it is otherwise unqualified if uniformly the tested axiality of contact explanation is qualified.
