Utility model content
Technical problem to be solved in the utility model is the simple measurement mechanism of a kind of structure that cannot realize measuring seal groove in small diameter for etalon and provide.
The utility model adopts following technical scheme: seal groove diameter measuring device in a kind of, comprise sounding rod, seat, dial gauge, bar, depression bar, described seat one end is measuring junction, other end connecting handle, measuring junction has slideway, slide block is provided with in slideway, slide block connects push rod spring, the push rod spring other end connects upper cover plate, upper cover plate is fixed with interchangeable sounding rod, one end that upper cover plate is relative is provided with plug, sounding rod runs through plug and can slide along perforation, sounding rod is positioned at one end of one end connecting link of plug, centre and the seat of bar are hinged, the other end of bar is connected with the contact of dial gauge, on dial gauge arranges and is present, one section between bar pin joint and dial gauge contact point is connected with spring base, spring base is located on seat, spring base is provided with pull-rod spring, depression bar is connected by connecting plate bottom spring base, bearing is articulated with in the middle part of depression bar, on bearing is fixed and is present.
The part that described sounding rod is positioned at plug is provided with circlip for shaft.
Described interchangeable sounding rod with between upper cover plate for being threaded, fastening by hexagonal nut.
Pad is provided with between described pull-rod spring and seat.
Described pull-rod spring is spacing by nut, and nut is fixed on spring base top.
Described bearing is connected with seat by sunk screw.
Described sounding rod and the tie point of bar, the other end of bar are equal with length between seat pin joint with the contact point distance bar of dial gauge.
The beneficial effects of the utility model can realize Measurement accuracy to seal groove diameter in small diameter, the present invention mainly make use of lever principle, because measured bore dia is less, meter tool cannot be put into, therefore front end arranges the meter bar of reduced size, during use, meter bar is placed in seal groove, be connected with dial gauge below by lever, lever arm before and after appearance etc., therefore the distance of front end meter bar movement is reflected on dial gauge equally, and first calibrate with outside micrometer before dial gauge, zero, during measurement, dial gauge scale changing value is exactly and standard-sized difference, thus measure the diameter dimension of interior seal groove.
