Description

Background
Due to the characteristic of high flexibility, the hose is generally applied to a launching field and other related test systems, and the butt joint of the interface flanges is generally carried out manually. The large-caliber low-temperature flange has the problems of difficult butt joint due to heavy weight and high requirement on centering precision. In the butt joint process, a plurality of persons are required to lift the flanges in a matching mode, and the two butt joint flanges are centered through the up-down left-right movement and the rotation of the flange surfaces, so that the centering precision is very high and is usually required to be within 0.1 mm. After butt joint, operations such as tightening of the connecting bolt according to moment, tightening of precooled secondary moment and the like are required. In order to reduce the working intensity of personnel and realize an automatic butt joint technology with high efficiency and high precision, the automatic and quick butt joint and the compression of the hose are realized by adopting a hose quick and automatic butt joint technology at present.
The centering of the joint is the key of the automatic butt joint process of the hose. The automatic centering of the hose connector has two schemes, which are respectively as follows: according to the first scheme, automatic tracking butt joint is adopted, a measuring system or a position sensor transmits the target position of a reference hose to a controller, the target elongation of each actuating element is obtained through inverse kinematics of a multi-degree-of-freedom motion mechanism, the signal is input into a servo system of the actuating element, each actuating element is driven to act after links of the controller, a servo amplifier and a servo valve are carried out, and the pose of the actuating hose is adjusted to approach a target value. Meanwhile, the actual strokes of the actuating elements are detected by the displacement sensors and fed back to the controller, so that closed-loop control is formed. Scheme II: the mechanical positioning automatic centering butt joint is adopted, the center of the pipe orifice at one end is taken as a reference, the automatic centering of the pipe orifice of the butt joint is carried out through a mechanical structure, namely, the sleeve is adopted for carrying out primary alignment; then the whole body is pushed to the position to be connected by the hydraulic cylinder, and the accurate alignment is completed in the pushing process; at the moment, the hydraulic cylinder is unloaded, and the spring release force pushes the driving ring to move downwards so that the clamping jaws close to clamp the pipe sleeve to complete connection. Comparing the two schemes, the first scheme has wide application range, and can be particularly used for dynamic connection conditions. The method is suitable for dynamic tracking of the reference tube under the condition of environmental disturbance such as air flow, liquid flow and the like. But is expensive. And the scheme II is simple and reliable, and the centering precision is higher. But only suitable for the fixed connection condition, namely, the centering is realized by adopting a mechanical positioning device under the condition that the reference tube is not moved. But the coarse positioning process of the second scheme is too coarse, and the sleeve structure is not easy to enter the butt joint. And the modulus of elasticity of the spring is susceptible to temperature, the sealing force provided at different temperatures may not be consistent. Therefore, a hose butt joint method or device suitable for low temperature is urgently needed.
