Problems solved by technology

Since the diameter of the barrel is too small and the length is relatively long, it is impossible to design a special forming measuring tool. The qualification of the barrel rifling angle can only be judged indirectly by whether the sample column can pass through. The accuracy is low, and the rifling cannot be accurately obtained. wrap angle data

Abstract

The invention discloses a detecting device for rifling angle of a small-caliber gun barrel. The base of the device is used as the mounting carrier of the whole device. An adaptor seat is connected with the base through a screw thread. A front sliding copper sleeve and a back sliding copper sleeve respectively sleeve the base and the adaptor seat. A connecting shaft is connected with the other end of the adaptor seat through a screw thread. The other end of the connecting shaft is connected with a locking nut through a screw thread. A coder mounting sheet is fixedly connected with the inner hole of the base through a screw. A coder is snapped on the coder mounting sheet. A bearing seat is fixedly connected with the other end of the base through a screw thread. The detecting device is suitable for detecting the rifling angles of the small-caliber gun barrels with different specifications. Furthermore the detecting device has advantages of simple structure, easy operation, high detecting precision and high suitability for popularization.

Description

technical field [0001] The invention belongs to the technical field of detection devices, and in particular relates to a small-caliber gun barrel rifling angle detection device. Background technique [0002] At present, there is no good detection method for the winding angle of small-caliber barrel rifling in China, especially for the detection of the winding angle of helical rifling in deep holes with a diameter of less than 40 mm. Since the diameter of the barrel is too small and the length is relatively long, it is impossible to design a special forming measuring tool. The qualification of the barrel rifling angle can only be judged indirectly by whether the sample column can pass through. The accuracy is low, and the rifling cannot be accurately obtained. Angle data. Contents of the invention [0003] For the above, the technical problem to be solved in the present invention is to provide a small-caliber gun barrel rifling angle detection device, which can realize the...
