Description
Technical field
It the utility model is related to form and position tolerance detection technique field, and in particular to a kind of steel pipe inside and outside circle concentricity is quickly examined
Survey device.
Background technology
Steel pipe is a kind of very extensive tubing of application, and it is usually by Fine Steel Casting iron, structural alloy steel or not
The material manufactures such as rust steel form.It is higher in many occasions for needing to use steel pipe, all the concentricity proposition to steel pipe inside and outside circle
It is required that.In order to ensure the concentricity requirement of steel pipe inside and outside circle, steel pipe needs to carry out the concentricity of inside and outside circle before manufactory dispatches from the factory
Detection.
In the prior art, the detection for steel pipe inside and outside circle concentricity mainly has three kinds of methods, first, using slide measure
Or whether the wall thickness of outside micrometer measurement steel pipe circumference everywhere is uniform, obtains the concentric degrees of data of steel pipe inside and outside circle indirectly, this
Kind method needs to carry out steel pipe multiple wall thickness measuring, and its is less efficient, and the numerical value measured is limited on circumference
Point, measurement data are not the measurement data of circle.Second, steel pipe is placed on v block, dial gauge is then set up, by hundred
The endoporus of point table side head contact steel pipe, then slowly rotate steel pipe and detected, this measuring method be only applicable to lighter in weight and
The shorter steel pipe concentricity measurement of length, rotation steel pipe is more laborious when heavier-weight work length is longer, and labor intensity is big, and compared with
Long steel pipe easily rocks in rotation process and influences measurement accuracy.Third, measured using the dial gauge with V-type seat,
During measurement, by V-type seat be positioned at steel pipe it is cylindrical on, the measurement head of dial gauge is contacted to the endoporus of steel pipe, passes through manual rotation V
Type seat, V-type seat is set to rotate a circle around steel pipe, the reading for obtaining dial gauge is the concentricity of steel pipe inside and outside circle, this measurement side
Method is because it is in measurement process, and dial gauge will follow V-type seat to rotate one around steel pipe together and enclose, the reading of dial gauge in measurement process
Number disks can not oriented manipulation person all the time, when dial gauge turns to its reading dial direction down, operator must bend down body, face
It is extremely inconvenient towards the number of degrees for observing dial gauge up, operation；When in addition using general dial indicator holder measurement, its connection hundred above
Divide the connecting rod of table easily to be rocked in rotary course, cause measurement data inaccurate.
Utility model content
In order to solve the above-mentioned technical problem, realize that steel pipe inside and outside circle concentricity is convenient, detect exactly, the utility model carries
Go out a kind of steel pipe inside and outside circle concentricity device for fast detecting with V-shaped positioning surface, its technical scheme is as follows：
