Abstract

The utility model provides a gauge for measuring excircle dimension and roundness of parts, which can be used for measurement of excircle of parts of different sizes, has good universality and helps to reduce detection costs. The gauge includes a base plate. The base plate is provided with a meter frame, a positioning block, and at least two centering screws. The positioning block is provided with a center. A dial indicator is fixedly arranged in the mounting cavity of the meter frame. A measuring head of the dial indicator is towards the center of the positioning block. The at least two centering screws are respectively toward the center of the positioning block. The gauge is characterized in that: the thread of the centering screw penetrates through an upper radial threaded hole of a stud, the central thread of the centering screw is connected with a nut, the nut is closely attached to the outer ring surface of the stud, the lower threaded section of the stud is in threaded connection with a threaded sleeve, and the bottom of the threaded sleeve is supported on the surface of the base plate.

Description

A kind of cubing of measuring part excircle dimension and circularity
Technical field
The utility model relates to the technical field that detects part cylindrical cubing, is specially a kind of cubing of measuring part excircle dimension and circularity.
Background technology
Existing cylindrical amount instrument can only be measured the circularity of the part cylindrical of fixed diameter, level altitude, and versatility is very poor, the height of part cylindrical or diameter are in case change will be measured, and its versatility is too poor, make different excircle dimensions join special-purpose cylindrical amount instrument, cost is too high.
Summary of the invention
At the problems referred to above, the utility model provides a kind of cubing of measuring part excircle dimension and circularity, and it can be used for the measurement of different size part cylindrical, and its versatility is good, and has reduced the detection cost.
A kind of cubing of measuring part excircle dimension and circularity, its technical scheme is such: it comprises base plate, be furnished with dial framework on the described base plate, locating piece, the centering screw, described locating piece is provided with the center, dial gauge is installed in the installation cavity of described dial framework, the gauge head of described dial gauge is towards the center of described locating piece, described centering screw has two at least, it is respectively towards the center of described locating piece, it is characterized in that: described centering screw thread runs through the top radial screw bore of double-screw bolt, the middle part of the described centering screw nut that has been threaded, described nut is close to the outer ring surface of described double-screw bolt, the lower thread section of the double-screw bolt thread bush that is threaded, the bottom of described thread bush is supported on the upper surface of described base plate, the described base plate of the below, center of described locating piece has threaded hole, described locating piece is supported on the upper surface of positioning screw, the threaded portion of the described positioning screw described threaded hole that is threaded.
It is further characterized in that: the below of described base plate is provided with set screw, and the below of described dial framework is fastenedly connected described base plate by screw;
The bottom of described thread bush is anchored on described base plate by screw;
The below of described positioning screw is provided with pressing plate, and screw is anchored on described positioning screw after running through described pressing plate, and the lower surface of described base plate is close in the upper surface of described pressing plate.
After adopting structure of the present utility model, at first make corresponding excircle dimension standard ring, according to the diameter of the part cylindrical of required measurement, adjust the position of centering screw, use nut to fix; Height according to required measurement part cylindrical, adjust the height of positioning screw and then adjustment locating piece, after being ready to complete, put into cylindrical standard ring, the gauge head of dial gauge is aimed at cylindrical standard ring, finish the school zero to dial gauge, afterwards part is placed the upper surface of locating piece, measure cylindrical circularity and excircle dimension by dial gauge; The height of part cylindrical or diameter be in case change, and can finish coupling with part by the height to middle distance, locating piece of adjusting the centering screw, and it can be used for the measurement of different size part cylindrical, and its versatility is good, and has reduced the detection cost.
