Description
Technical field
The utility model relates to a kind of small size internal diameter π chi, belongs to direct-reading diameter measurement utensil technical field.
Background technology
The method that the internal 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 that tactful flexible article produces distortion when measuring jaw clamping object and cannot measure, 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 diameter of size, therefore π chi is measure the conventional inspection measuring device tool of internal-and external diameter at present, but π chi need coil into round shape when measuring, although methodological science and advanced, because the superposition of blade easily causes the error of artificial vision when reading data, and conveniently unlike slide calliper rule vernier to read.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, even cannot measure, and 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 small size internal diameter π chi.
A kind of small size internal diameter π chi of the present utility model, it comprises blade, internal diameter main scale, internal diameter main scale scale mark layer, internal diameter secondary chi, internal diameter sub scale line layer, spacer section, the left end chi face of blade is provided with internal diameter main scale, the dual-side of internal diameter main scale is provided with internal diameter main scale scale mark layer, the right-hand member chi face of blade is provided with the secondary chi of internal diameter, the dual-side of the secondary chi of internal diameter is provided with internal diameter sub scale line layer, and the centre position of blade is provided with spacer section.
As preferably, described blade designs for list structure, adopts elastic gelatin sheet to make, there is elasticity, the transparent film of flexible one-tenth deep camber, be convenient to read data, the π chi overcoming other materials cannot measure the Embarrassing state that cannot read data for deep camber workpiece.
The beneficial effects of the utility model: its reasonable in design, measuring method science, measuring accuracy is high, by utilizing the funtcional relationship of circular constant, measuring accuracy is made to improve π doubly, stable physical property, the difficult problem that other π chis cannot be measured small size workpiece can be solved, be suitable for industry many, can be used on all trades and professions such as machine-building processing, rubber plastic product, petrochemical complex, boats and ships Submarine manufacture, hydraulic and electric engineering, Aero-Space, solve the accurate measurement of flexible piece.
Accompanying drawing explanation
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 after the utility model bends.
1-blade; 2-internal diameter main scale; 3-internal diameter main scale scale mark layer; The secondary chi of 4-internal diameter; 5-internal diameter sub scale line layer; 6-spacer section.
Embodiment
As Fig. 1, shown in Fig. 2, this embodiment is by the following technical solutions: it comprises blade 1, internal diameter main scale 2, internal diameter main scale scale mark layer 3, internal diameter secondary chi 4, internal diameter sub scale line layer 5, spacer section 6, the left end chi face of blade 1 is provided with internal diameter main scale 2, the dual-side of internal diameter main scale 2 is provided with internal diameter main scale scale mark layer 3, the right-hand member chi face of blade 1 is provided with the secondary chi 4 of internal diameter, the dual-side of the secondary chi 4 of internal diameter is provided with internal diameter sub scale line layer 5, and the centre position of blade 1 is provided with spacer section 6.
Wherein, described blade 1 designs for list structure, adopts elastic gelatin sheet to make, there is elasticity, the transparent film of flexible one-tenth deep camber, be convenient to read data, the π chi overcoming other materials cannot measure the Embarrassing state that cannot read data for deep camber workpiece.
This embodiment is substantially identical with the using method of general π chi, if survey the size of internal diameter, from secondary chi 4 end of internal diameter, blade 1 is coiled into the disk also less than measured workpiece internal diameter, then puts it in internal diameter, natural resiliency according to chi is adjacent on inner hole of workpiece wall, just can reading.
This embodiment reasonable in design, measuring method science, measuring accuracy is high, by utilizing the funtcional relationship of circular constant, measuring accuracy is made to improve π doubly, stable physical property, the difficult problem that other π chis cannot be measured small size workpiece can be solved, be suitable for industry many, can be used on all trades and professions such as machine-building processing, rubber plastic product, petrochemical complex, boats and ships Submarine manufacture, hydraulic and electric engineering, Aero-Space, solve the accurate measurement of flexible piece.
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.
