Automatic detection method and device of wall thickness of perforating bullet energy concentrating cover

Abstract

The invention relates to an automatic detection method and an automatic detection device of the wall thickness of a perforating bullet energy concentrating cover, belonging to the field of the manufacture of a perforating bullet used for oil-gas field exploitation, in particular to automatic measurement, detection and spinning equipment of the perforating bullet energy concentrating cover. The automatic detection method of the perforating bullet energy concentrating cover measures the wall thickness on an automatic detection device of the perforating bullet energy concentrating cover, which is controlled by an external PLC; when in measurement, firstly, the measured perforating bullet energy concentrating cover is placed into a measuring cup, and an axial line of the perforating bullet energy concentrating cover is ensured to be coaxial with an axial line of the measuring cup and perpendicular to a work table surface. The automatic detection device comprises a stand, a left laser length measuring sensor, a right laser length measuring sensor, the measuring cup, a stepping motor, a bearing seat, two deep groove ball bearings, a sensor support frame, a bearing end cover, a main shaft, and the like. The invention adopts the external PLC to control the stepping motor to drive the perforating bullet energy concentrating cover to rotate and adopts the left laser length measuring sensor and the right laser length measuring sensor to detect the wall thickness, and collected measuring signals are processed and operated by the external PLC, thereby the invention has high detection efficiency, high precision, safety and reliability.

Description

technical field [0001] The invention relates to an automatic detection method and device for the wall thickness of a perforating charge energy-collecting cover, which belongs to the production field of perforating charge mining for oil and gas fields, and particularly relates to automatic weighing of perforating charge energy-forming cover metal powder, automatic spinning equipment and wall thickness Automatic measurement technology. Background technique [0002] In the well-known production process of perforating bullets used in oil and gas fields, the uniformity of the wall thickness of the energy-enhancing cover directly affects the production capacity, quality and production cost. Therefore, in the manufacturing process, the uniformity of the wall thickness must be strictly controlled. At present, most of the perforating charge manufacturing enterprises use the dial gauge measurement method to manually measure the wall thickness of the energy-concentrating cover. This t...
