Detailed description of the preferred embodiments
The present invention will be described in further detail with reference to the drawings and reference numerals.
As shown in fig. 1-10; a lens outer diameter measuring jig comprises a sliding block 1, a guide post 2 and a base 3;
the sliding block 1 is connected with the base 3 through the guide post 2;
the tail end of the guide post 2 is fixedly connected with a knob 6 through a cross screw 8 and a baffle 7;
the inside of the base 3 is provided with a trapezoid cavity, and a copper gasket 4 is accommodated in the trapezoid cavity; the tail end of the base 3 is embedded with a pressing sleeve 5;
the guide post 2 penetrates through a pressing sleeve 5 and a copper gasket 4 in the base 3 to be connected with the sliding block 1 in a threaded manner.
The guide post 2 is connected with the knob 6 in a triangular or square clamping manner.
The tail end of the pressing sleeve 5 is provided with a convex edge.
The sliding block 1 and the base 3 are of inclined structures, and the measuring range is between 2 and 10 MM.
The slider 1 and the base 3 are machined from stainless steel, and excellent accuracy can be maintained.
Examples:
in the measuring process, the measuring tool selects a low force measuring height gauge for measuring, so that the accuracy of measuring data can be ensured. In the testing process, the product is put into a proper position according to the drawing size of the outer diameter of the actual lens. And (3) zeroing the height gauge according to the plane area of the base, continuously moving 2 positions to ensure that the ground is parallel and the data are consistent, sequentially shearing the tested product, vertically placing the product in the test area of the base, enabling the shearing opening to face the product and place the product at an angle of 30-150 degrees with the reference surface, enabling the product to be in contact with the test reference surface, and finally measuring and reading the data.
