Problems solved by technology
The reverse-installed separation nut device cannot directly observe and confirm whether the "T"-shaped bolt head is installed in place in the catcher, and the blind installation operation will cause a hidden danger in the connection of the separation nut device; in order to reduce the risk, ensure that the "T"-shaped bolt head is installed Correct, the operator can only rely on experience to confirm repeatedly, and the operation process time is greatly increased

Embodiment
[0042] The invention provides a reverse-installation and separation nut device for convenient docking operation, which eliminates the hidden danger of blind installation, simplifies the installation and inspection process, and shortens the operation time. The technical scheme of the anti-installation and separation nut device of the present invention is as follows:
[0043] The reverse-installed separation nut device is composed of a butt bolt 1, a catcher assembly 2 and a separation nut assembly 3, and the structure is as shown in the appendix. figure 1 shown.
[0044] The head of the butt bolt 1 adopts an octagonal structure, and the front section of the head is a tapered surface. The catcher assembly 2 is composed of two parts: a catcher housing 4 with a butt bolt catch function and a catcher base 5 with both reverse-loading and bearing functions. The top end of the catcher housing 3 adopts an adaptive passive deformation cone for catching the butt bolts 1 after separatio...

An anti-installation separation nut device for convenient docking operation, comprising: a butt bolt, a catcher assembly and a separation nut assembly. The catcher assembly is installed on the docking frame on one side of the payload, and the separation nut assembly is installed on the docking frame on the side of the rocket; the docking bolt is used to connect the catcher assembly and the separation nut assembly to make the payload dock with the rocket; docking operation Before, the butt bolts are preset in the catcher assembly through the slot structure; during the docking operation, the butt bolts are pulled out from the catcher assembly through the tooling, so that the butt bolts are threadedly connected with the separation nut assembly. The invention eliminates the hidden danger of human operation caused by the blind installation operation in the reverse installation process, does not need repeated confirmation in the operation process, and greatly shortens the operation time.
Description
technical field [0001] The invention relates to a reverse-mounted separation nut device for convenient docking operation, belonging to the field of structural design of a launch vehicle pyrotechnic separation device. Background technique [0002] The separation nut device is a point-type separation device widely used for the connection and separation of the payload and the rocket docking surface. It consists of a catcher assembly, a separation nut assembly and a butt bolt. The catcher is installed on the docking frame on the payload side, and the separation nut assembly is installed on the docking frame on the rocket side. The catcher assembly and the separation nut assembly are connected by butt bolts to realize the docking between the payload and the rocket. [0003] When the payload is docked with the rocket, under the normal operation procedure, the catcher assembly and the separation nut assembly are pre-installed on their respective docking frames, and the butt bolts a...
