Abstract

The utility model relates to a measuring tool, particularly to a special measuring tool for the central hole of perforating charge. The measuring tool comprises a handle, and is characterized in that a no-go gauge is arranged at the end part of the handle; a go gauge is arranged at the front end of the no-go gauge; both the go gauge and the no-go gauge are in the shape of columns; and the external diameter of the go gauge is smaller than that of the no-go gauge. The measuring tool has the characteristics of high measuring accuracy and batch inspection efficiency, low manufacturing cost, simple structure and the like.

Description

Perforating bullet center pit special measuring tool
Technical field
The utility model relates to a kind of measurer, especially relates to a kind of perforating bullet center pit special measuring tool.
Background technology
As everyone knows, at present a lot of producers are to utilize kind of calliper when producing perforating bullet shell case product mostly, or take multiple measurements by the cartoon rule of single-ended no-go gage or drift.Forms repeatedly because of measurer is different when actual production and measure, thereby can't guarantee the measuring accuracy of product size, the relative product detection stand-by period is also very long, and the efficient of measure batch is lower, and the manufacturing cost of a plurality of measurers is higher relatively.
Summary of the invention
The utility model mainly is a technical matters low at the existing in prior technology measuring accuracy, that batch detection efficient is low, manufacturing cost is high, and the perforating bullet center pit special measuring tool of a kind of measuring accuracy height, batch detection efficient height, low cost of manufacture is provided.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of perforating bullet center pit special measuring tool, comprise handle, it is characterized in that described handle end is provided with no-go gage, the no-go gage front end is provided with drift, described drift and no-go gage are all cylindrical, and the external diameter of described drift is less than the external diameter of no-go gage.The perforating bullet center pit special measuring tool that has drift and no-go gage by the end respectively, only plug once, just can check whether perforation hole shell hole footpath size is qualified, should end drift compares with the cartoon rule of kind of calliper or single-ended no-go gage or drift, it is low to have cost of manufacture, batch detection efficient height, the advantage that measuring accuracy is high, whether logical range estimation intuitive judgment aperture is qualified, or super upper and lower tolerance.
As preferably, the external diameter of described drift is smaller or equal to the perforating bullet internal diameter, and the external diameter of described no-go gage is greater than the perforating bullet internal diameter.During measurement, the outside dimension of drift is the lower limit in perforating bullet aperture, the external diameter of no-go gage is the high limit of size in aperture, when drift can be by aperture and no-go gage can not be when the aperture, be that aperture size is qualified, otherwise be defective, drift can not be represented the super following tolerance in product hole by aperture, and promptly the aperture is too small; No-go gage also can be represented the super last tolerance in product hole by aperture, and promptly the aperture is excessive.
As preferably, described handle outside surface is provided with the annular knurl layer.Can the handle place be carried out the cylindrical annular knurl handle according to actual needs, the friction force that has increased the handle place is so that operation.
As preferably, described handle is cylindrical, and the external diameter of described handle is greater than the external diameter of drift.Handle simple in structure, easy to operate, columniform helps the operator grasps measurer and measures.
As preferably, described handle two ends are provided with no-go gage and drift.Can be according to needs of production, select that the handle two ends only are provided with drift respectively or an end is provided with only drift, simple in structure, manufacturing cost is cheap relatively.
Therefore, the utlity model has measuring accuracy height, batch detection efficient height, low cost of manufacture, characteristics such as simple in structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Accompanying drawing 2 is another kind of structural representations of the present utility model.
Accompanying drawing 3 is a kind of structural representations of perforating bullet that utilization the utility model is measured.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Shown in Figure of description 1,3, a kind of perforating bullet center pit special measuring tool comprises handle 1, and handle end is provided with no-go gage 2, and the no-go gage front end is provided with drift 3, and drift and no-go gage are all cylindrical, and the external diameter of drift is less than the external diameter of no-go gage.The external diameter of drift is smaller or equal to the perforating bullet internal diameter, and the external diameter of no-go gage is greater than the perforating bullet internal diameter.The handle outside surface is provided with annular knurl layer 4.Handle is cylindrical, and the external diameter of handle is greater than the external diameter of drift.
The perforating bullet center pit special measuring tool that has drift and no-go gage by the end respectively, only plug once, just can check whether perforation hole bullet 5 pore sizes are qualified, should end drift compares with the cartoon rule of kind of calliper or single-ended no-go gage or drift, it is low to have cost of manufacture, batch detection efficient height, the advantage that measuring accuracy is high, whether logical range estimation intuitive judgment aperture is qualified, or super upper and lower tolerance.During measurement, the outside dimension of drift is the lower limit in perforating bullet aperture, the external diameter of no-go gage is the high limit of size in aperture, when drift can be by aperture 6 and no-go gage can not be when the aperture, be that aperture size is qualified, otherwise be defective, drift can not be represented the super following tolerance in product hole by aperture, and promptly the aperture is too small; No-go gage also can be represented the super last tolerance in product hole by aperture, and promptly the aperture is excessive.
Embodiment 2:
Shown in Figure of description 2,3, a kind of perforating bullet center pit special measuring tool comprises handle 1, and the handle two ends are respectively arranged with no-go gage 2, and the no-go gage front end is provided with drift 3, and drift and no-go gage are all cylindrical, and the external diameter of drift is less than the external diameter of no-go gage.The external diameter of drift is smaller or equal to the perforating bullet internal diameter, and the external diameter of no-go gage is greater than the perforating bullet internal diameter.The handle outside surface is provided with annular knurl layer 4.Handle is cylindrical, and the external diameter of handle is greater than the external diameter of drift.
The perforating bullet center pit special measuring tool that has drift and no-go gage by the end respectively, only plug once, just can check whether perforation hole bullet 5 pore sizes are qualified, should end drift compares with the cartoon rule of kind of calliper or single-ended no-go gage or drift, it is low to have cost of manufacture, batch detection efficient height, the advantage that measuring accuracy is high, whether logical range estimation intuitive judgment aperture is qualified, or super upper and lower tolerance.During measurement, the outside dimension of drift is the lower limit in perforating bullet aperture, the external diameter of no-go gage is the high limit of size in aperture, when drift can be by aperture 6 and no-go gage can not be when the aperture, be that aperture size is qualified, otherwise be defective, drift can not be represented the super following tolerance in product hole by aperture, and promptly the aperture is too small; No-go gage also can be represented the super last tolerance in product hole by aperture, and promptly the aperture is excessive.
