Description
Technical field
The utility model is related to a kind of diameter instruments of inspection of nonstandard product, more particularly to a kind of inspection man of nonstandard leaf
Tool.
Background technology
Leaf is the critical component of the electric equipment products such as automobile, motorcycle, electric horn.The diameter of leaf is generally
2.00mm-10.00mm, thickness are generally 0.5mm-1.5mm, and leaf diameter is small, and thickness is thin, and to the essence of leaf geomery
Degree requires very high.Leaf has the round leaf of standard, also there is nonstandard quasi-circular leaf, so-called nonstandard quasi-circular leaf such as Fig. 1
Shown, there are one notches on outside diameter hoop so that its outer diameter is not complete round for one, for the leaf of this shape
Traditional circular product diameter instruments of inspection can not be used, thus can not accurately judge whether its geomery reaches design requirement.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, and diameter dimension can accurately be examined by providing one kind,
And the nonstandard quasi-circular leaf internal-and external diameter instruments of inspection of internal-and external diameter inspection can be carried out at the same time.
In order to achieve the above object, a kind of nonstandard quasi-circular leaf internal-and external diameter instruments of inspection designed by the utility model,
It includes outer diameter proving ring and internal diameter check rod, and the outer diameter proving ring is ring-shaped structure, and wolfram steel ring is arranged in through-hole,
The internal diameter of the wolfram steel ring is consistent with the outer diameter shape of nonstandard quasi-circular leaf and size, the side of the outer diameter proving ring through-hole
Circumference is set as chamfer shape；The internal diameter check rod includes cleansing pin, and one section of wolfram steel circle, the wolfram steel circle are arranged with outside cleansing pin
Outer diameter it is consistent with the nonstandard internal diameter size of quasi-circular leaf.
Increase the comfort level that worker holds outer diameter proving ring for operating easily, described its through-hole of outer diameter proving ring has
The one side of chamfer shape is set as concave inward structure, and another side is set as outer male structure.The outer diameter size of outer diameter proving ring is general
For 2-5cm.
The length of cleansing pin and the length of wolfram steel circle need to design according to inspection, and general cleansing pin length is 30-50cm, wolfram steel
The length of circle is the 1/3-1/2 of cleansing pin length.
When utility model works, nonstandard quasi-circular leaf is sleeved on cleansing pin one by one first, sequentially passes through wolfram steel circle, such as
Leaf can pass through wolfram steel circle to judge its internal diameter size qualification, if leaf can not judge its internal diameter size mistake by wolfram steel circle
It is small to be unqualified, it is removed from cleansing pin.The leaf of internal diameter qualification continues to examine outer diameter, and the tip of cleansing pin is examined from outer diameter
There is ring the through-hole side of chamfer shape to be inserted into, and outer diameter proving ring sequentially passes through the leaf on cleansing pin, as leaf can be by outer
Wolfram steel ring in diameter proving ring through-hole judges its outer diameter qualification, if leaf can not pass through the tungsten in outer diameter proving ring through-hole
Steel loop judges that its outer diameter is crossed greatly unqualified, first removes qualified leaf and outer diameter proving ring, then will from cleansing pin
Underproof leaf is removed from cleansing pin, then covers the inspection that top external diameter proving ring continues leaf outer diameter again.
The utility model is used cooperatively by outer diameter proving ring and internal diameter check rod, can examine nonstandard quasi-circular simultaneously
The inside/outside diameter size of leaf, it is outer with nonstandard quasi-circular leaf by being designed as the geomery of wolfram steel ring in outer diameter proving ring
Diameter geomery one, which is shown, to be achieved the purpose that effectively to examine, can will be multiple by the design of internal diameter check rod cleansing pin and wolfram steel circle
Leaf series connection is examined, and realizes the efficiency that inspection is improved while internal diameter examines purpose.Therefore, it has simple in structure, design
The features such as rationally and easy to use.

Specific implementation mode
The utility model will be further described below in conjunction with the accompanying drawings.
As Figure 2-Figure 5, a kind of nonstandard quasi-circular leaf internal-and external diameter instruments of inspection of the present embodiment description, it includes outer
Diameter proving ring and internal diameter check rod, the outer diameter proving ring are ring-shaped structure, and wolfram steel ring 2, the tungsten are arranged in through-hole 1
The internal diameter of steel loop is consistent with the outer diameter shape of nonstandard quasi-circular leaf and size, and the side circumference of the outer diameter proving ring through-hole is set
It is set to chamfer shape 3；The internal diameter check rod includes cleansing pin 4, and one section of wolfram steel circle 5 is arranged with outside cleansing pin, the wolfram steel circle
Outer diameter is consistent with the nonstandard internal diameter size of quasi-circular leaf.
There is described its through-hole of outer diameter proving ring the one side of chamfer shape to be set as concave inward structure, and another side is set as outer
Male structure.The outer diameter size of outer diameter proving ring is 2-5cm.
The length of the cleansing pin is 30-50cm, and the length of wolfram steel circle is the 1/3-1/2 of cleansing pin length.
