Description
Technical field
The utility model relates to a kind of enhancement mode special-shaped internal diameter π chi, belongs to direct-reading diameter measurement utensil technical field.
Background technology
The method that the internal-and external diameter of current measuring workpieces is comparatively commonly used adopts slide calliper rule or milscale to measure exactly, require measuring claw clamping object, this has 2 insoluble problems to measuring appliances such as slide calliper rule, one is measure flexible article to produce when measuring jaw clamping object and to be out of shape and cannot Measurement accuracy, two is radiuses that the length of the measuring claw measuring large cylinder or bigbore object slide calliper rule milscale must exceed measured body, before guarantee precision, make large-scale measurer under topic is very difficult, even if there have large-scale measurer to operate to be also abnormal heavy, π chi is just extremely important for this reason can near object, object receiving force can be made again evenly and not deformation to occur, the much data that all can read mean diameter of size, therefore π chi is measure the conventional detection utensil of internal-and external diameter at present, but π chi need coil into round shape when measuring, although methodological science and advanced, but because the superposition of blade easily causes the error of artificial vision when reading data.In addition, π chi need coil into round shape when measuring, and to the object of different-diameter because the difference of radius-of-curvature produces the additive error measured, deals with improperly and also can cause certain error when this illustrates that internal-and external diameter measured by π chi in a word.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of enhancement mode special-shaped internal diameter π chi.
A kind of enhancement mode of the present utility model special-shaped internal diameter π chi, it comprises bar shaped strip blade, main scale, secondary chi, spacer section, ruler window, the left end chi face of bar shaped strip blade is provided with main scale, the right-hand member chi face of bar shaped strip blade is provided with secondary chi, one end of secondary chi is provided with ruler window, one side of main scale and secondary chi is provided with scale mark layer, and is oppositely arranged up and down, the centre position of bar shaped strip blade is provided with spacer section.
The beneficial effects of the utility model: its measuring method science, easy to carry, measuring accuracy is high, utilize π funtcional relationship cleverly, make measuring accuracy improve π doubly, main scale inserts the nearlyer step of secondary chi and ensure that precision, and measurement range is wide, be suitable for industry many, can be applicable to the industries such as machine-building processing, rubber plastic product, petrochemical complex boats and ships Submarine manufacture, hydraulic and electric engineering, Aero-Space.
accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model measures object.
1-bar shaped strip blade; 2-main scale; The secondary chi of 3-; 4-spacer section; 5-ruler window.
embodiment:
As Fig. 1, shown in Fig. 2, this embodiment is by the following technical solutions: it comprises bar shaped strip blade 1, main scale 2, secondary chi 3, spacer section 4, ruler window 5, the left end chi face of bar shaped strip blade 1 is provided with main scale 2, the right-hand member chi face of bar shaped strip blade 1 is provided with secondary chi 3, and one end of secondary chi 3 is provided with ruler window 5, and a side of main scale 2 and secondary chi 3 is provided with scale mark layer, and be oppositely arranged up and down, the centre position of bar shaped strip blade 1 is provided with spacer section 4.
The using method of this embodiment: from secondary chi 3 end of this π chi along the same xsect of object under test carry out circumference around, this chi is made to be close to testee, after one week, main scale 2 is through the ruler window 5 of secondary chi 3, reads by cursor principle the measurement that data complete diameter.
This embodiment measuring method science, easy to carry, measuring accuracy is high, utilize π funtcional relationship cleverly, make measuring accuracy improve π doubly, main scale inserts the nearlyer step of secondary chi and ensure that precision, and measurement range is wide, be suitable for industry many, can be applicable to the industries such as machine-building processing, rubber plastic product, petrochemical complex boats and ships Submarine manufacture, hydraulic and electric engineering, Aero-Space.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
