Accompanying drawing 3 is positioning disk surface structure schematic diagram.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1, 2, a kind of simple coaxial degree detection means, including positioning disk 1 and pass through magnetic stand 5 and dial framework 7
Lever indicator 8 of the device on the positioning disk 1, by rotational positioning disk 1, realizes the effect of detection axiality, described determines
The positioning pit 9 for installing place kick 3 is provided with the lower surface and side periphery of position disk 1, and place kick 3 passes through epoxy resin
Glue or other can the glue of bonded metal be fixed in positioning pit 9, also place kick 3 and positioning pit 9 can be provided with interference fit,
Prevent it from falling down, the positioning pit 9 set on the lower surface of positioning disk 1 there are three, and uniform centered on the axle center of positioning disk 1, uses
The minimum point of place kick 3 in this positioning pit 9 is collectively forming a plane (determine face) at 3 points and the datum plane of detected workpiece is affixed
Close, the friction between measured workpiece can be reduced when in use.The positioning pit 9 set on the side periphery of positioning disk 1 has two
Individual, the angle in two axle center of 9 relative positioning disk of positioning pit 1 is less than 180 °, and two positioning pits 9 are located at the same cross section of positioning disk 1
On, with the place kick 3 in this two positioning pits 9, contacted from the center solstics of positioning disk 1 with measured workpiece datum hole inwall,
No matter how datum hole inwall, which changes at this 2 points, to be fitted in all the time on benchmark hole wall.It is additionally, since the side cylinder table of positioning disk 1
Two positioning pits 9 are provided with face, when making positioning disk 1, the dimension precision requirement of positioning disk 1 is not high, and its diameter is without tolerance
Limitation, the roughness of periphery, hardness, geometrical and toleranging are also not required to be strict with two positioning without required precision
The position in hole 9, the upper surface of described positioning disk 1 is provided with rotation handle 2, and the rotation handle 2 passes through on the upper surface of positioning disk 1
The screwed hole of setting is fixed on positioning disk 1, and preferably screwed hole has two, and is respectively positioned on using the axle center of positioning disk 1 as the same of the center of circle
On one circle, two side periphery place kick 3 on rotation handle 2, positioning disk 1 are pulled to be close to benchmark by arc path
Hole inwall, is rotated around benchmark centerline hole, and then makes it drive the superincumbent lever indicator of absorption to surround datum hole profile
Face rotates, and realizes the measurement to being detected face.And the structure of the positioning disk 1 is modified slightly can be applied to the survey of solid shafting
Amount.
For stably measured effect, the place kick 3 that the lower surface of positioning disk 1 is set also is located at using the axle center of positioning disk 1 as the center of circle
Same circle on, two place kick on the periphery of side are contour relative to the lower surface of positioning disk 1, by positioning disk when using
