Description
Technical field
The utility model relates to a kind of inner hole groove measurement mechanism.
Background technology
At present, in machining, the inner hole groove diameter of some parts cannot be measured, and machine-tool operator can only roughly be determined according to drawing control index dial the diameter of groove, causes machine-tool operator and checker often to conflict.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, and a kind of inner hole groove measurement mechanism is provided, and it can accurately measure the diameter of inner bore of part groove, has avoided producing between machine-tool operator and checker the phenomenon of contradiction.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of inner hole groove measurement mechanism, it comprises sleeve body, microdrum, central shaft and at least two sounding rods, at least two sounding rods are distributed on the radially perisporium of sleeve body slidably, microdrum is arranged on sleeve body, central shaft can axially movably be bearing on sleeve body, when described central shaft is connected with microdrum to rotates microdrum, central shaft moves axially with respect to sleeve body, described central shaft has sounding rod driving body, the tail end of at least two sounding rods is all flexibly connected with sounding rod driving body, and in the time of rotation microdrum, sounding rod equals the move axially distance of central shaft with respect to sleeve body with respect to the distance that moves radially of sleeve body, between the tail end of sounding rod and sounding rod driving body, be provided with retracing spring.
Further, in order to prevent that sounding rod driving body from exceeding restriction stroke, on described sleeve body, backing pin is installed, and this backing pin matches with sounding rod driving body.
When a kind of structure is further provided with box lunch rotation microdrum, sounding rod equals the move axially distance of central shaft with respect to sleeve body with respect to the distance that moves radially of sleeve body, described sounding rod driving body is cone structure, and the cone bevel angle of this cone structure is α, and tan α=0.5.
Further, sounding rod is three.
Adopt after technique scheme, in the time measuring the diameter of inner hole groove, rotation microdrum, the head of sounding rod is stretched in inner hole groove, central shaft often moves axially 1mm, and sounding rod at its sleeve body in the radial direction, namely stretches into the also mobile 1mm of distance of inner hole groove, as long as proofread and correct out with a standard endoporus diameter that on measurement mechanism position, sounding rod records, just can extrapolate the diameter of surveyed inner hole groove like this.
Brief description of the drawings
