Reason need to measure the spiral section outer diameter within the scope of each screw pitch in dimension control.And spiral coil specification type is more,
Big specification screw diameter is up to 2000mm.How screw diameter is accurately measured to the quality of final products and the inspection knot of product
Fruit has vital influence.
The measurement of spiral coil screw diameter, traditional method are to be measured with micrometer, but spiral coil has spiral shell
Lift angle is revolved, the practical value measured of micrometer is not diameter projected, and screw pitch is bigger, and error is bigger.Another method height vernier
Slide calliper rule, but have big specification spiral coil and the spiral coil of fine pitch in product, and need to the spiral shell within the scope of each screw pitch
Rotation section outer diameter measures, and when practical operation does not have enough operating spaces, it is difficult to realize to different angles within the scope of each screw pitch
Spend the measurement of spiral section diameter.
Invention content
Present invention aims at the measurement for big specification spiral coil and the spiral coil screw diameter of fine pitch, gram
It takes traditional measurement method error and is difficult to the problem carried out with measurement operation greatly, a kind of simple in structure, measurement easily to operate is provided
The device and spiral coil screw diameter measurement method of spiral coil screw diameter.
The present invention to achieve the above object, adopts the following technical scheme that：
A kind of device measuring spiral coil screw diameter, it is characterised in that：Including reference platform, it is arranged on reference platform
Spiral coil bearing device；It is provided with height measuring device above the reference platform, the height measuring device is along the spiral shell
Capstan pipe moves axially.
It is further characterized by：The bearing device is the identical carrying roller of two diameters, and the carrying roller is parallel to described
The center line synchronizing moving of reference platform.
Further：Nylon coated outside the carrying roller, internal sleeve ball bearing are through on main shaft.
Preferably：The height measuring device is laser displacement sensor, and the laser displacement sensor is arranged described
On portal frame above reference platform, it is located at right over the reference platform center line, and measurement direction is perpendicular to the benchmark
