Abstract
The utility model relates to a spiral mircrometer gauge, in particular to a cylindrical surface spiral mircrometer gauge, which comprises a screw rod, a fixed sleeve, a microdrum, an anvil block and an arc frame, wherein the fixed sleeve is fixedly arranged at one end of the arch frame, the screw rod is connected with the inner radial surface of the fixed sleeve through screw threads, one end of the screw rod extends out of the fixed sleeve and is opposite to the anvil block arranged at the other end of the arch frame, the other end of the screw rod is fixedly connected with the inner bottom of the microdrum, the microdrum is sheathed on the surface of the fixed sleeve, the surface of the anvil block in contact with an object to be measured is not a plane, and a cylindrical surface groove and a spherical surface groove are respectively arranged on the plane, so the alignment of the center axial line of a cylinder rod element or a ball body to be measured and the center line of the anvil block can be ensured, and the measurement is more accurate. The spiral mircrometer gauge is suitable for being used in occasions such as schools, factories and the like.
Description
Technical field:
The utility model relates to a kind of micrometer caliper, is a kind of cylinder micrometer caliper specifically.
Background technology:
At present, the surface that the micrometer caliper anvil block that factory or school use contacts with testee is the plane, when measured object is cylinder rod member or sphere diameter, owing to the little easy off-center axis of area that contacts with cylinder or sphere, causes measuring error big.
Summary of the invention:
The purpose of the utility model is to provide a kind of more accurate micrometer caliper.
The utility model comprises screw rod, fixed muffle, microdrum, anvil block and shelf; Fixed muffle is fixed on an end of shelf, and screw rod and fixed muffle aperture surface spiral join, and the anvil block that screw rod one end stretches out the fixed muffle and the shelf other end is relative; The other end and microdrum inner bottom part are fixedly connected; Microdrum is enclosed within the fixed muffle surface, it is characterized in that: the face that anvil block contacts with testee is not the plane, but has cylinder groove and spherical groove in the plane.
The beneficial effect of the utility model: a cylinder groove is left on the contacted plane of anvil block and testee on the utility model; With a spherical groove; So just can guarantee that measured circle mast spare or ball centre axis align with the anvil block center line, make measurement more accurate.
Description of drawings:
Fig. 1 is the utility model micrometer caliper structural representation.
Fig. 2 is the utility model anvil block partial structurtes synoptic diagram.
Among the figure: 1 screw rod, 2 fixed muffles, 3 microdrums, 4 anvil blocks, 5 shelves, 6 cylinder grooves, 7 spherical grooves.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further to specify.
Referring to Fig. 1; Fig. 2, the utility model comprise screw rod 1, fixed muffle 2, microdrum 3, anvil block 4 and shelf 5, and fixed muffle 2 is fixed on an end of shelf 5; Screw rod 1 joins with fixed muffle 2 aperture surface spirals; The anvil block 4 that screw rod 1 one ends stretch out the fixed muffle 2 and shelf 5 other ends is relative, and the other end and microdrum 3 inner bottom parts are fixedly connected, and microdrum 3 is enclosed within fixed muffle 2 surfaces; It is characterized in that: the face that anvil block 4 contacts with testee is not the plane, but has cylinder groove 6 and spherical groove 7 in the plane.
During use, measured circle mast spare is contacted with cylinder groove 6 on the anvil block,, so just can guarantee that measured circle mast spare or ball centre axis align with the anvil block center line, make measurement more accurate perhaps with 7 joints of the spherical groove on tested spheroid and the anvil block.
The utility model suits to use in occasions such as school, factories.
