A vertical column and a lifting device are perpendicularly installed on a base, a V-shaped groove capable of rotating by 360 degrees is formed in the upper end of the vertical column, a sliding V-shaped groove is formed in the V-shaped groove capable of rotating by 360 degrees, and a camera is installed at the upper end of the lifting device. A positioning mechanism is installed at the bottom of the V-shaped groove capable of rotating by 360 degrees, a spring positioning pin is arranged on the positioning mechanism, positioning holes which are symmetrically distributed by 180 degrees are formed in the side walls of the vertical column, and the height of the positioning holes is the same as that of the spring positioning pin. By the adoption of the V-shaped grooves, the angle of a line of centers of two end holes of a bar is observed, and the lead of the bar is calculated according to the angle and the diameter and the length of the bar. By the adoption of a rotating device and the positioning holes, the end faces of the bar are automatically positioned to be perpendicular to the camera, the bar does not need to be touched or moved, and therefore detection accuracy is guaranteed. The camera is used for projecting inner holes in the two end faces of the bar to be detected and a connecting line of the inner holes on the same plane, the included angle of the line of centers of the inner holes is measured, and the lead is calculated according to the screw lead and the angle principle.
Description
Technical field
The present invention relates in a kind of hard alloy cold threaded hole helical pitch detection means, for cold threaded hole in hard alloy
The helical pitch detection of bar or cutter and other general measuring methods cannot detect the rod-shaped objects of endoporus helical pitch information.
Background technology
At present, detection of the domestic hard alloy manufacturer to cold threaded hole bar lead of screw in hard alloy is generally adopted and surveyed
Method of the amount external screw thread helical pitch to identify interior cold threaded hole helical pitch, because interior cold threaded hole internal and external threads helical pitch has certain mistake
Difference, and this detection method is also higher to the skill set requirements of operator, error generally in ± 1mm, therefore, use outer spiral shell
Stricture of vagina helical pitch cannot accurately reflect endoporus lead of screw.Cutter manufacturer processing in cold helical tooth blade when, due to detect helical pitch
With the difference of actual endoporus helical pitch, it is easy during fluting due to cumulative errors especially when making sword length and being more than 100mm cutters
Endoporus is caused to be opened brokenly.
And offshore company identifies helical pitch information using the endoporus lead of screw of measurement bar, although accuracy of detection is higher,
But testing equipment principle used is complicated, and expensive.
The content of the invention
