Detailed description of the invention
With embodiment, the present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, a kind of simple coaxial degree detection device, including location dish 1 and by magnetic stand 5 and dial framework 7
Device lever indicator 8 on this location dish 1, by rotational positioning dish 1, it is achieved the effect of detection axiality, described determines
It is provided with, on the lower surface of position dish 1 and side periphery, the positioning pit 9 installing place kick 3, and epoxy resin is passed through in place kick 3
Glue or other can the glue of bonded metal be fixed in positioning pit 9, it is possible to place kick 3 and positioning pit 9 are provided with interference fit,
Preventing it from falling down, the positioning pit 9 that location dish 1 lower surface is arranged has three, and uniform centered by location dish 1 axle center, uses
Place kick 3 minimum point in this positioning pit 9 is collectively forming the datum plane of a plane (determining face at 3) and detected workpiece and is affixed
Close, can reduce in use and friction between measured workpiece.The positioning pit 9 arranged on the periphery of location dish 1 side has two
Individual, the angle in two positioning pit 9 relative localization dish 1 axle center is less than 180 °, and two positioning pits 9 are positioned at the same cross section of location dish 1
On, with the place kick 3 in these two positioning pits 9, from solstics, location dish 1 center and measured workpiece datum hole contact internal walls,
No matter how datum hole inwall changes at these 2 can be fitted on benchmark hole wall all the time.It is additionally, since location dish 1 side cylinder table
Being provided with two positioning pits 9 on face, when making location dish 1, the dimension precision requirement of location dish 1 is the highest, and its diameter is without tolerance
Limiting, the roughness of periphery, hardness, geometrical and toleranging, all without required precision, are also not required to be strict with two location
The position in hole 9, the upper surface of described location dish 1 is provided with turning handle 2, and this turning handle 2 is by location dish 1 upper surface
The screwed hole arranged is fixed on location dish 1, and preferably screwed hole has two, and is respectively positioned on to position same as the center of circle of dish 1 axle center
On one circle, pulling turning handle 2 by arc path, benchmark is close in two side periphery place kick 3 on location dish 1
Hole inwall, rotates around datum hole centrage, and then makes it drive the superincumbent lever indicator of absorption around datum hole profile
Face rotates, it is achieved the measurement to detected face.And the structure of this location dish 1 is modified slightly i.e. can be applicable to the survey of solid shafting
Amount.
For stably measured effect, the place kick 3 that location dish 1 lower surface is arranged also is located at positioning dish 1 axle center as the center of circle
Same circle on, two place kick on the periphery of side are contour relative to the lower surface of location dish 1, will position dish during use
1 puts into measured workpiece datum hole, with datum plane and benchmark Internal hole positioning, and three place kick 3 being positioned at location dish 1 lower surface
With the plane contact having perpendicularity to require in measured workpiece datum hole, two are positioned at dish side, location periphery place kick 3 and quilt
Survey workpiece datum hole contact internal walls, by arc to promoting two turning handles 2, rotation detection device, make two side peripheries
Place kick 3 is moved along the datum hole inwall of measured workpiece so that it is drives and adsorbs superincumbent lever hundred by magnetic stand 5
Point table is around datum hole central rotation, thus measures the measured face of cylinder coaxiality error relative to center axis of reference hole.
It is understood that above with respect to the specific descriptions of the present invention, be merely to illustrate the present invention and be not limited to this
Technical scheme described by inventive embodiments, it will be understood by those within the art that, still can carry out the present invention
Amendment or equivalent, to reach identical technique effect；As long as meet use needs, all protection scope of the present invention it
