Abstract
The invention discloses an intermediate inner hole pass-stop gauge. The pass-stop gauge can be used for intuitively and simultaneously judging whether the size, the roundness and the taper of an inner hole are qualified. The pass-stop gauge comprises a cylindrical big end, a cylindrical small end and an intermediate connecting bar for connecting the big end and the small end; one end of the cylindrical big end close to the outside and one end of the cylindrical small end close to the outside are provided with chamfers; and the diameter of the intermediate connecting bar is smaller than the diameters of the big end and the small end.
Description
Technical field
The present invention relates to the intermedium of turbosupercharger, be specially the logical no-go gage of intermedium endoporus.
Background technology
In the process of the intermedium of turbosupercharger; For the size that guarantees the intermedium endoporus qualified; Need internal hole dimension to measure accurately, the measurement to endoporus all is to use micrometer inside caliper at present, and its operation is efficient and convenient inadequately; Reduced work efficiency, and micrometer inside caliper can not judge whether the circularity of intermedium endoporus and tapering be qualified.
Summary of the invention
To the efficient and convenient inadequately of micrometer inside caliper measuring operation and can not judge the shortcoming of circularity and tapering; The invention provides the logical no-go gage of intermedium endoporus; It is simple in structure, and is easy to operate, can judge simultaneously intuitively whether interior hole dimension, circularity and tapering be qualified.
Its technical scheme is such: the intermedium endoporus leads to no-go gage; It is characterized in that: the middle pitman that it comprises the big end of the cylinder bodily form and small end and is connected big end and small end; An outer end of described tubular big end and small end all is provided with chamfering, and the diameter of described middle pitman is less than the diameter of big end and small end.
After the present invention adopts said structure,, can make things convenient for whether hole dimension, circularity and tapering meet the requirements in the direct judgement through the endoporus of logical no-go gage turnover intermedium.And its cost is lower than micrometer inside caliper.
Description of drawings
Fig. 1 is the structural representation of the logical no-go gage of intermedium endoporus.
Embodiment
Like Fig. 1, middle the pitman 3 that the present invention includes the big end 1 of the cylinder bodily form and small end 2 and be connected big end 1 and small end 2 holds 1 all to be provided with chamfering with the outer end of small end 2 greatly, and the diameter of middle pitman 3 is less than the diameter of big end 1 and small end 2.
After intermedium endoporus completion of processing; After blowing off workpiece with air gun; Measure with the logical no-go gage of intermedium endoporus, can unobstructed turnover endoporus and hold 1 tighterly greatly when small end 2, can judge that processing dimension is qualified; When logical no-go gage passed in and out endoporus, whether circularity and the tapering of observing endoporus simultaneously met the workpiece requirement.
Claims (1)
1. the intermedium endoporus leads to no-go gage; It is characterized in that: the middle pitman that it comprises the big end of the cylinder bodily form and small end and is connected big end and small end; An outer end of described tubular big end and small end all is provided with chamfering, and the diameter of described middle pitman is less than the diameter of big end and small end.
