Abstract
The utility model relates to an aperture measurement device. The aperture measurement device comprises a barrel body, wherein a pair of radial holes is symmetrically formed in the circumferential wall of the barrel body; a contact is arranged in each radial hole by means of slide fit; one end of the contact stretches into the axial hole of the barrel body, and the other end of the contact penetrates out from the orifice of a radial hole located in the circumferential wall surface of the barrel body; an inclined surface is arranged on the end part stretching into the axial hole of the barrel body, of the contact; the contact is sleeved with a conical spring; one end of the spring is connected with the contact, and the other end of the spring is fixed with the barrel body; a sleeve is arranged in the axial hole of the barrel body, and one end of the sleeve stretches out to the outside of the axial hole of the barrel body and then is connected with a dial gauge; the measuring bar of the dial gauge stretches into the sleeve, and the end part of the measuring bar is conical. The aperture measurement device disclosed by the utility model is capable of accurately measuring a an aperture and free from damages to hole wall.
Description
Technical field
The utility model relates to a kind of aperture measurement device.
Background technology
Adopt at present conventionally the aperture of gauge ball measurement products, i.e. gauge ball perforation hand-manipulated, see gauge ball when perforation whether can by or by backstop.For example, the gauge ball large if little gauge ball can pass through is by backstop, and aperture is qualified.But there is following shortcoming in this metering system:
(1) when gauge ball passes through the hole of product, between gauge ball and the hole of product, have relative motion, easy and hole wall friction, damages hole wall, causes product bad;
(2) when product aperture is near critical value, different operators detects, and because dynamics used is different, can draw different testing results;
(3) gauge ball is after long-time use, and self easily weares and teares, and makes measurement result inaccurate.
Summary of the invention
For above-mentioned technical matters, fundamental purpose of the present utility model is for a kind of aperture measurement device that can Measurement accuracy bore dia is provided, and can not produce injury to hole wall.
Aperture measurement device, comprise cylindrical shell, in the circumferential wall of cylindrical shell, be arranged with a pair of radial hole, a contact is slidably matched in each radial hole, one end of contact extend in the axial hole of cylindrical shell, the other end of contact passes from being positioned at the aperture of the radial hole cylindrical shell circumference wall, the end that contact extend into the axial hole of cylindrical shell is provided with inclined-plane, on contact, cover has the spring of taper, one end of spring is connected with contact, the other end and the cylindrical shell of spring are fixed, in the axial hole of cylindrical shell, be provided with a sleeve, one end of this sleeve is connected with a dial gauge after reaching the axial hole outside of cylindrical shell, the measuring staff of dial gauge extend in sleeve, the end of this measuring staff is for being conical.
Adopted such scheme, when the aperture of product is measured, cylindrical shell is inserted in hole, make the measuring staff of dial gauge along cylindrical shell axial displacement, in place the moving past in journey of measuring staff contacts with the inclined-plane on two contacts, when measuring staff continues displacement, promote contact to the displacement of cylindrical shell radial direction, one end that contact is positioned at cylindrical shell circumference wall outside finally contacts with wall surface of the hole, when measuring staff cannot continue displacement, illustrate that two contacts all contact reliably with wall surface of the hole, at this moment read the upper reading of dial gauge, then by calculating the aperture value that can portal.
Further, also comprise a back up pad, this back up pad is provided with threaded hole, and described cylindrical shell is threaded with threaded hole.Because back up pad can be placed on the end face of product in use, and can, according to the degree of depth in hole, adjust cylindrical shell and extend into the degree of depth in hole, so that a plurality of positions in hole are measured.
Accompanying drawing explanation
Fig. 1 is aperture measurement device structural representation of the present utility model;
1 is cylindrical shell, and 2 is contact, and 3 is spring, and 4 is sleeve, and 5 is dial gauge, and 6 is measuring staff, and 7 is back up pad.
Embodiment
With reference to Fig. 1, a kind of aperture measurement device of the present utility model, comprise cylindrical shell 1, in the circumferential wall of cylindrical shell 1, be arranged with a pair of radial hole, a contact 2 is slidably matched in each radial hole, one end of contact 2 extend in the axial hole of cylindrical shell, and the other end of contact 2 passes from being positioned at the aperture of the radial hole cylindrical shell circumference wall, and the end that contact 2 extend into the axial hole of cylindrical shell is provided with inclined-plane.On contact 2, cover has the spring 3 of taper, and one end of spring 3 is connected with contact 2, and the other end of spring 3 and cylindrical shell 1 are fixing.In the axial hole of cylindrical shell, be provided with a sleeve 4, one end of this sleeve 4 is connected with a dial gauge 5 after reaching the axial hole outside of cylindrical shell 1, and the measuring staff 6 of dial gauge extend in sleeve, and the end of this measuring staff is for being conical.Also comprise a back up pad 7, this back up pad 7 is provided with threaded hole, and described cylindrical shell 1 is threaded with threaded hole 8.
Claims (2)
