Abstract
The invention provides a checking tool for measuring the size and roundness of an excircle of a part. The checking tool can be used for measuring excircles of parts in different sizes and is high in generality, and detection cost is lowered. The checking tool comprises a baseplate, a gauge frame, a positioning block and at least two centering screws are arranged on the baseplate, the positioning block is provided with a center, a dial gauge is fixedly mounted in a mounting cavity of the gauge frame, a measuring head of the dial gauge faces the center of the positioning block, and the centering screws face the center of the positioning block respectively. The checking tool is characterized in that threads of the centering screws penetrate through upper-portion radial threaded holes of studs, middle threads of the centering screws are connected with nuts which are appressed on outer ring faces of the studs, threads in lower-portion thread sections of the studs are connected with threaded sleeves, bottom ends of the threaded sleeves are supported to the upper surface of the baseplate, and a threaded hole is reserved on the baseplate below the center of the positioning block.
Description
Technical field
The present invention relates to detect the technical field of part cylindrical cubing, be 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 invention provides a kind of cubing of measuring part excircle dimension and circularity, 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 invention, 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.
