Description
Technical field
The utility model relates to a kind of instrument of measuring concentricity, relates in particular to a kind of instrument of measuring the tubular article concentricity.
Background technology
Now, the instrument of a lot of measurement concentricitys is arranged on the market, generally all be to use high precision instrument or ray that article surface or level or vertical direction are measured, the data that draw are accurate, accurate.Instrument such on the market costs an arm and a leg, and operation steps is many, and working environment is had certain requirement, measures when being not suitable for producing tubular article in enormous quantities.
The utility model content
It is low, simple to operate that a purpose of the present utility model provides a kind of cost, the measurement when being fit to factory mass production tubular article.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:
A kind of instrument of measuring the tubular article concentricity comprises base and the montant vertical with base, and described montant is provided with two holders, cross tube that described holder fixedly is parallel to each other and sheer pole; Described cross tube one end connects a upper locking device, instrument of upper locking device locking, and described instrument comprises panel board and instrument bar, there is a detection head that can stretch described instrument bar bottom; The corresponding end of described sheer pole and described upper locking device is connected with a following locking device, and following locking device locking has a plug, and plug is vertical with described instrument bar.
Plug of the present utility model is used to accept measured tubular article, the gap of described tubular article and plug socket is little, above-mentioned detection head can accurately be measured the wall thickness and the concentricity of tubular products, some partial shape that promptly ought be enclosed within the tubular article in the columned plug of standard is not simultaneously, tubular products with above-mentioned reacting condition to detection head on, thereby the staff can be from the corresponding reading of the panel board that links to each other with detection head.
As preferably, described holder adjustable ground is arranged on the described montant.
The holder adjustable ground is arranged on the described montant, can make montant can be suitable for the tubular products of multiple thickness, thereby by regulating the distance that detection head and tubular products surface are regulated in the position of holder on montant.
As preferably, described upper locking device and following locking device are welded on an end of the cross tube of correspondence and an end of sheer pole with it.Upper locking device locking instrument is welded on the disturbance that can avoid instrument on the cross tube more effectively with it.Those of ordinary skill in the art should be known in that the utility model can also adopt alternate manner to guarantee locking device and the relative fixed between the device of being locked, for example integral type connection etc.
As preferably, on the described panel board zero resetting device is arranged.
Be provided with zero resetting device on described panel board, the pointer on the adjusting apparatus dial plate returns zero easily, so just can obtain tubular article and the deviation size plug central shaft rapidly and intuitively.
As preferably, the axis of described detection head and described plug axis are in the same plane.
Instrument bar of the present utility model and detection head are cylindric, their dead in line, because instrument bar of the present utility model is vertical with plug, therefore, the axis of the detection head in the technique scheme is with in the axis of plug is in same plane and vertical, moving fully on its axis direction of detection head, and detection head disturbance in the axial direction is exactly the disturbance of tubular article on radial direction.
As preferably, below the little 0.01mm of internal diameter of described plug external diameter than tested tubular article.
Said structure can guarantee the no-float between tested tubular article and the plug fully, is unlikely to allow the disturbance between tubular article and the plug that measurement structure is produced bigger influence again.
As preferably, described plug is parallel to described sheer pole, and described instrument bar is perpendicular to sheer pole.
In sum, the utlity model has following beneficial effect:
Of the present utility model simple in structure, low price, easy to operate, little to the working environment requirement, be fit to measure when tubular article in enormous quantities is produced.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1-base, 2-montant, 3-sheer pole, 4-holder, 5-cross tube 6-upper locking device, locking device under the 7-, 8-instrument, 8a-instrument, 8b-instrument bar, 8c-detection head, 9-plug, 10-nut.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this instructions, but as long as all are subjected to the protection of Patent Law in claim of the present utility model.
As shown in Figure 1, the utility model is a kind of instrument of measuring tubulose gauge concentricity, comprise base 1 and the montant 2 vertical with base 1, montant 2 is provided with two holders 4, cross tube 5 that holder 4 fixedly is parallel to each other and sheer pole 3, the adjustable positions of holder 4 saves land and is arranged on the montant 2, regulates holder 4 like this and just can regulate distance, angle between cross tube 5 and the sheer pole 3.Upper locking device 6 of cross tube 5 one ends welding, instrument 8 of upper locking device 6 lockings, instrument 8 comprises panel board 8a and instrument bar 8b, there is a detection head 8c that can stretch instrument bar 8b bottom, a nut 10 of adjusting pointer position among the panel board 8a is set on the panel board 8a, can allows panel board 8a have back zero by rotating nut 10.Following locking device 7 of sheer pole 3 and upper locking device 6 corresponding end welding, plug 9 of following locking device 7 lockings, below the little 0.01mm of internal diameter of plug 9 external diameters than tested tubulose gauge, plug 9 is parallel with sheer pole 3, instrument bar 8b also is parallel to sheer pole 3, and the axis of the detection head 8c on the instrument bar 8b and the axis of plug 9 are in the same plane.
The utility model is used to measure the concentricity of hollow bushing-like gauge, at first select a plug 9 that matches with measured gauge internal diameter size, with following locking device 7 described plug 9 is locked, then tested gauge is enclosed within outside the plug 9, regulate holder 4, distance in the change between the sheer pole or angle make detection head 8c just be pressed onto tested article surface, adjust nut 10 this moment makes the indication of panel board 8a make zero, and instrument 8 is just in running order.The hand rotation or the tested gauge that stretches, the tested relatively article apparent motion of detection head 8c, the rotation of coiling pointer on the 8a that cares for appearances in the rotation or the tested article that stretch changes, if needle deflection surpasses the maximal value of permission, illustrates that then the concentricity of tested gauge is undesirable; If needle deflection illustrates then that less than the maximal value that allows this tested gauge concentricity or thickness meet the requirements.
