Abstract
The utility model relates to a portable checking device for dial gages, wherein, the principle of which uses a complete micrometer head (1) as the measurement standard for checking a dial gage. An outer connecting sleeve (2), a screw nut (4), an inner taper sleeve (5) and a gripping sleeve (6) are fixed at the front part of the micrometer head (1). When the utility model is used, a measuring bar of a dial gage (7) to be checked is inserted into an inner hole of the gripping sleeve (6) from the front end of the gripping sleeve (6), the screw nut (4) is screwed, the inner taper sleeve (5) is pushed to slide forward, and three claw valves of an outer cone part in the front of the gripping sleeve (6), so that the measuring bar of the dial gage (7) to be checked is gripped, and then the micrometer head (1) can be used for checking the dial gage to be checked. The utility model has the advantages of accurate checked results and convenient carryover for field use.
Description
The utility model belongs to the inspection machine of field of instrumentation technology, is a kind of portable dial gauge comparator.
Dial gauge is a metering outfit commonly used in the Mechanical Manufacturing Enterprises, for guaranteeing the accuracy of metering numerical value, must often examine and determine it.Calibrating instrument commonly used at present is a SB-3 type dial gauge comparator, and the result of its calibrating is accurate, but its volume is big, and examine and determine at the scene of being not easy to.
The purpose of the utility model just is to develop its advantage and overcomes its shortcoming, and a kind of portable dial gauge comparator of both accurately being convenient to execute-in-place is provided.
The purpose of this utility model is achieved in that a kind of portable dial gauge comparator, by micrometer head (1), be fixed on the anterior outer adapter sleeve (2) of micrometer head (1) by means of holding screw (3), be fixed on the interior gripping sleeve (6) of outer adapter sleeve (2) front end by means of holding screw (3), be positioned at the nut (4) of gripping sleeve (6) middle front part, the inner conical drogue (5) that is positioned on the anterior Outer Taper of gripping sleeve (6) is formed, the measuring staff of dial gauge to be checked (7) inserts in the endoporus of gripping sleeve (6) from the front end of gripping sleeve (6), it is characterized in that: micrometer head (1), outer adapter sleeve (2), nut (4), inner conical drogue (5), gripping sleeve (6), and the measuring staff of dial gauge to be checked (7), their longitudinal center line is on same straight line.Simultaneously, the anterior outside surface of gripping sleeve (6) is an Outer Taper, this Outer Taper and inner conical drogue are to be slidingly matched between (5), and this Outer Taper is directly upwards had three axial notches by sawing at it, have three pawl lobes that clamp function under external force thereby this Outer Taper is become.Examine and determine when using, as long as the measuring staff of dial gauge to be checked (7) is inserted in the endoporus of gripping sleeve (6) from the front end of gripping sleeve (6), turn nut (4), promote inner conical drogue (5) to front slide, three pawl lobes of the anterior Outer Taper of gripping sleeve (6) are closed up, thereby clamp the measuring staff of dial gauge to be checked (7).At this time just can examine and determine dial gauge to be checked with micrometer head (1).
Adopt actual effect of the present utility model to be: verification result accurately, this comparator volume is little simultaneously, is easy to carry, and can operate at the scene.
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a scheme of erection of the present utility model.
Fig. 2 is the A-A sectional view of the gripping sleeve (6) among Fig. 1.
By accompanying drawing as seen, the right is a complete micrometer head (1), and its effect is the measurement standard as the calibrating dial gauge.Its front portion, outer adapter sleeve (2), its effect of being fixed with a tubulose by means of holding screw (3) are that micrometer head (1) is connected with other each parts.It is fixed on gripping sleeve (6) by means of another holding screw (3) inside of its front end again.Gripping sleeve (6) is the pipe box of a structure more complicated: the outside of its middle front part is shaped on pin thread, matches with nut (4); The outside surface of its front portion is an Outer Taper, and this Outer Taper and inner conical drogue are to be slidingly matched between (5); Simultaneously, this Outer Taper is directly upwards had three axial notches by sawing at it, has three pawl lobes that clamp function under external force thereby this Outer Taper is become; The measuring staff of dial gauge to be checked (7) can insert in the endoporus of gripping sleeve (6) from the front end of gripping sleeve (6).Such structure and array mode, its purpose make gripping sleeve (6) both have the effect that connects each part exactly, have the effect of dial gauge to be checked (7) that are fixedly clamped again.Clearly, the measuring staff of micrometer head (1), outer adapter sleeve (2), nut (4), inner conical drogue (5), gripping sleeve (6) and dial gauge to be checked (7), their longitudinal center line are all on same straight line.
Examine and determine when using, as long as the measuring staff of dial gauge to be checked (7) is inserted in the endoporus of gripping sleeve (6) from the front end of gripping sleeve (6), turn nut (4), promote inner conical drogue (5) to front slide, three pawl lobes of the anterior Outer Taper of gripping sleeve (6) are closed up, thereby clamp the measuring staff of dial gauge to be checked (7).At this time just can examine and determine dial gauge to be checked with micrometer head (1).
Claims (3)
1, a kind of portable dial gauge comparator, by micrometer head (1), be fixed on the anterior outer adapter sleeve (2) of micrometer head (1) by means of holding screw (3), be fixed on the interior gripping sleeve (6) of outer adapter sleeve (2) front end by means of holding screw (3), be positioned at the nut (4) of gripping sleeve (6) middle front part, the inner conical drogue (5) that is positioned on the anterior Outer Taper of gripping sleeve (6) is formed, the measuring staff of dial gauge to be checked (7) inserts in the endoporus of gripping sleeve (6) from the front end of gripping sleeve (6), it is characterized in that: micrometer head (1), outer adapter sleeve (2), nut (4), inner conical drogue (5), gripping sleeve (6), and the measuring staff of dial gauge to be checked (7), their longitudinal center line is on same straight line.
2, comparator according to claim 1 is characterized in that the anterior outside surface of said gripping sleeve (6) is an Outer Taper, and this Outer Taper and inner conical drogue are to be slidingly matched between (5).
