Description
Technical field
The utility model belongs to clamp technology field, relates in particular to the auxiliary clamp in a kind of accurate measurement aperture.
Background technology
Measure aperture and conventionally can measure with inside meter, universal tool-measuring microscope, three coordinate measuring machine etc., but high for required precision, measurement requirement cannot be measured or not reach to the less part in aperture with above metering system.Vertical optical meter is a kind of accurate length-measuring instrument, and the method for utilizing standard gauge block to compare with measured piece is measured the elementary errors size of External Shape, and measurement data is reliable and stable.Expansion string type inside meter is to utilize elastic measuring head through the most advanced and sophisticated probe with tapering, to promote the utensil of the precise inner diameter size of dial gauge, and gauge head head is spherical, can self-centering measure, and measures easily and fast.Inside meter scale division value is lower, to high-precision aperture, cannot accurately measure.Together with vertical optical meter not successfully being installed in expansion string type inside meter in prior art, obtain pinpoint accuracy and measure the auxiliary clamp of the device in aperture.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and the auxiliary clamp in a kind of simple in structure, easy to loading and unloading, the stable practical accurate measurement aperture that provides.
The utility model object and solve its technical problem underlying and realize by the following technical solutions:
The auxiliary clamp in accurate measurement of the present utility model aperture, comprise clamp body, clamp-screw, step up sheet, spring, wherein: described clamp body upside is provided with screwed hole, downside is provided with visual window, clamp-screw is housed in screwed hole, spring is equipped with in clamp body inside, and spring inner side is equipped with and is stepped up sheet, and clamp-screw head contacts with spring.
The auxiliary clamp in above-mentioned accurate measurement aperture, wherein: described visual window cross section is rectangle.
The auxiliary clamp in above-mentioned accurate measurement aperture, wherein: described spring is notched spring.
The auxiliary clamp in above-mentioned accurate measurement aperture, wherein: described in to step up sheet be arc.
The auxiliary clamp in above-mentioned accurate measurement aperture, wherein: described screwed hole becomes to be dislocatedly distributed with visual window.
The utility model compared with the existing technology has obvious advantage and beneficial effect.From above technical scheme, in described screwed hole, clamp-screw is housed, spring inner side is equipped with and is stepped up sheet, and clamp-screw head contacts with spring, is conducive to be pressurized to spring by rotation clamp-screw, and then pushes and step up sheet and realize fastening effect; Clamp body downside is provided with visual window, contributes to be observed the survey cap of vertical optical meter and the probe of gauge outfit are fitted by this visual window.The utility model is by providing fixture that expansion string type inside meter gauge outfit is arranged on vertical optical meter, makes to measure on the vertical optical meter of outside dimension also can measure high-precision aperture size, has simple in structure, easy to loading and unloading, the stable feature such as practical.

The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the auxiliary clamp specific embodiment, structure, feature and effect thereof to the accurate measurement aperture according to the utility model proposes, be described in detail as follows.
Referring to Fig. 1 to Fig. 5, the auxiliary clamp in accurate measurement of the present utility model aperture, comprise clamp body 1, clamp-screw 2, step up sheet 3, spring 4, wherein: described clamp body 1 upside is provided with screwed hole 5, downside is provided with visual window 6, and clamp-screw 2 is housed in screwed hole 5, and spring 4 is equipped with in clamp body 1 inside, spring 4 inner sides are equipped with and are stepped up sheet 3, and clamp-screw 2 heads contact with spring 4.Described visual window 6 cross sections are rectangle.Described spring 4 is notched spring.The described sheet 3 that steps up is for arc.Described screwed hole 5 is dislocatedly distributed with 6 one-tenth of visual windows.
During use, according to the pore size that will measure, select inside meter gauge outfit, extension bar 10 is connected with clamp body 1, then tighten rear clamp-screw 2; After the spring gauge head 9 that will rise is connected with clamp body 1, by visual window 6, the survey cap of vertical optical meter 7 and the spring gauge head 9 that rises are fitted, can start to measure, the spring gauge head 9 that rises promotes to survey cap 7 through the most advanced and sophisticated probe with tapering and can see graticle scale from vertical optical meter eyepiece.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
