Abstract

The invention discloses a rapid positioning and measuring device for an egg-shaped pressure-resistant shell, which includes a base, and a pair of clamping and centering mechanisms are arranged on the base, and each clamping and centering mechanism clamps one end of the egg-shaped pressure-resistant shell respectively. A measuring mechanism is installed on the base, and the measuring mechanism includes a supporting plate device arranged on the base. A through hole is arranged on the upper end of the supporting plate device, and a rotating shaft is installed in the through hole, and a circular positioning plate is arranged on the rotating shaft. The shaped positioning plate is provided with two circumferentially evenly distributed limiting holes, and four circumferentially uniformly distributed positioning pin mechanisms are installed on the support plate to match the limiting holes. The end of the rotating shaft is connected with the limiting plate, and the limiting The plate is provided with a groove, and a scale sliding along the groove is installed in the groove. The present invention adopts an active adjustment mechanism, a rotating scale mechanism and a wide measuring head, so that the egg-shaped pressure shell can be clamped and positioned conveniently and quickly, ensuring that the axis of the egg-shaped pressure shell is placed horizontally, and the short axis of the egg-shaped pressure shell can be aligned with the axis of the egg-shaped pressure shell. Long axis measurement has high precision and high efficiency.

Description

technical field

[0001] The invention relates to a rapid positioning measuring device and a measuring method for an egg-shaped pressure-resistant shell, belonging to the field of measuring. Background technique

[0002] The egg-shaped pressure hull is a rotating shell with a positive Gaussian curve. It has excellent mechanical properties under uniform loads and can be produced and applied to deep-sea submersibles. The long axis and short axis of the egg-shaped pressure shell are important factors affecting its own mechanical properties, so it is necessary to accurately measure the formed egg-shaped pressure shell after production and processing to ensure that its size meets the design requirements. At present, the most commonly used measurement tools are hand-held measuring instruments, such as vernier calipers, micrometers, calipers, etc., which are mainly aimed at the basic size measurement of conventional parts. The patent No. CN1334436A provides an accurate hand-held meas...
