The measuring tool has the advantages of high measuring accuracy and batch inspection efficiency, low manufacturing cost, simple structure, convenient use and the like.
Description
Technical field
The utility model relates to a kind of measurer, especially relates to a kind of right cylinder end groove milling special measuring tool.
Background technology
As everyone knows, at present a lot of producers are when producing perforating bullet shell case product, need carry out dimensional measurement to the perforating bullet groove milling, and need measure three significant dimensions when the perforating bullet groove milling carried out dimensional measurement, be the symmetry of groove milling width, the groove milling degree of depth and groove milling, this just needs manufacturer to take multiple measurements by a plurality of measurers.Forms repeatedly because of measurer is different in actual production process 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 right cylinder end groove milling 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 right cylinder end groove milling special measuring tool, comprise the measurer main body, it is characterized in that described measurer main body one end thickness is the width no-go gage of groove milling, measurer main body interior thickness is the groove depth no-go gage of groove milling, measurer main body other end thickness is the groove depth drift of groove milling, offer two circular holes on the concentric circles of being positioned at of symmetrical distribution between described groove depth no-go gage and the groove depth drift, the external diameter of circular hole is cylindrical drift, and the distance between described two circular holes is the width drift of groove milling.The utility model can be measured three significant dimensions of right cylinder end groove milling by a measurer, just can judge by range estimation and feel whether product is qualified, end the degree of depth and the width that drift is measured the groove milling of right cylinder end by the width and the degree of depth, guarantee the symmetry of product by the cooperation of distance between two circular holes and circular hole outside dimension, the symmetry of described product is the tolerance of right cylinder external diameter and the minimum value of groove width tolerance.
As preferably, the separatrix of the direction of two circular holes of described symmetrical distribution and the groove depth drift of groove milling and groove depth no-go gage is in vertical distribution.
As preferably, described measurer main body is circle or rectangle or polygon.Can the measurer body design be produced difformity according to needs of production, measurement purposes simple in structure, easily manufactured, as can be applicable to multiple different right cylinders end groove milling.
As preferably, the end face of described groove milling width no-go gage is the right angle.The end face of groove milling width no-go gage is the right angle, and measuring accuracy is high and easy to use, working strength is high.
As preferably, described measurer material of main part is Cr2 or CrMn or CrWMn.。Manufacturing cost is cheap relatively and working strength is high, high life.
As preferably, described measurer body surfaces thermal treatment HRC58-62.Measurer body surfaces thermal treatment HRC58-62 has improved working strength, has increased the service life.
As preferably, described measurer body surfaces is ground, gauge precision 0.005mm～0.01mm.Measuring accuracy height, easy to use.
Therefore, the utlity model has measuring accuracy height, batch detection efficient height, low cost of manufacture, characteristics such as simple in structure, easy to use.
Description of drawings
Accompanying drawing 1 is a kind of structural front view of the present utility model.
Accompanying drawing 2 is a kind of structure side views of the present utility model.
Accompanying drawing 3 is a kind of section of structures of slotted eye position in the utility model.

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 1,2,3,4, a kind of right cylinder end groove milling special measuring tool, comprise measurer main body 1, measurer main body one end thickness is the width no-go gage 3 of groove milling 6, measurer main body interior thickness is the groove depth no-go gage 4 of groove milling 6, measurer main body other end thickness is the groove depth drift 5 of groove milling 6, offer two circular holes 2 on the concentric circles of being positioned at of symmetrical distribution between groove depth no-go gage and the groove depth drift, the external diameter of circular hole is the drift of right cylinder 7, and the distance between two circular holes 2 is the width drift of groove milling 6.The direction of two circular holes that are symmetrically distributed and the groove depth drift 5 of groove milling 6 and the separatrix 8 of groove depth no-go gage 4 are in vertical distribution.Measurer main body 1 is circular.The end face of groove milling 6 width no-go gages 3 is the right angle.Measurer main body 1 material is Cr2.Measurer main body 1 surface heat is handled HRC58-62.1 surface grinding of measurer main body, gauge precision 0.005mm.Slotted eye and measurer body surfaces contact point offer protective trough 9, and protective trough 9 degree of depth are 0.5m, and protective trough 9 sections are rectangular.Avoided burr or point of a knife R angle the error after the groove milling effectively, improved accuracy of detection measuring.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.
When using right cylinder end groove milling special measuring tool groove milling being measured to perforating bullet, the gauger is inserted in the perforating bullet groove milling with the measurer main body earlier, two right cylinders that are about to the groove milling end pass two circular holes respectively and fix, distance between two circular holes is the width drift of groove milling, the gauger passes through the thickness difference between range estimation and feel judgement right cylinder and groove depth no-go gage and the groove depth drift again, thereby conveniently reaches the effect that detects the right cylinder end groove milling degree of depth.Can measure the width of groove milling with measurer main body one end width no-go gage the gauger takes off right cylinder end groove milling special measuring tool in the perforating bullet groove milling after, promptly qualified groove milling product is to insert with the width no-go gage.
