Abstract

The invention discloses a device for detecting liner thickness and a wall thickness difference, and relates to the technical field of wall thickness detection. The device for detecting the liner thickness and the wall thickness difference comprises an adjusting base and a turntable, wherein a vertical mounting plate is arranged on the adjusting base, and an angle-adjustable laser range finder is arranged on the vertical mounting plate; and the turntable is arranged on a light receiving side of the adjusting base, a magnetic base is arranged at the upper end of the turntable, and a liner mold is arranged on the magnetic base. According to the device for detecting the liner thickness and the wall thickness difference, the laser emitted by the laser range finder is used for measuring the liner thickness and the wall thickness difference, a non-contact measurement mode is adopted, the detection precision is improved, the scratch on the surface of a liner is reduced, and the magnetic base is used for achieving rapid replacement of the liner mold.

Description

technical field [0001] The invention relates to the technical field of wall thickness detection, in particular to a device for detecting the wall thickness and wall thickness difference of a drug-type cover. Background technique [0002] Perforating charge is a kind of well completion equipment used to establish effective channels in the wellbore and oil layer. Its quality will greatly affect the oil and gas production of production wells. Metal powder liner is the key component of perforating charge. The symmetry and uniformity of mass distribution are very critical to the perforating elastic performance. The actual processed liner inevitably has a wall thickness difference, and the quality of the liner has a significant impact on the formed jet. The wall thickness does not refer to The wall thickness of the drug-shaped cover along the circumferential direction changes, but the wall thickness that the drug-shaped cover should have in a certain cross section. [0003] At th...
