Embodiment 1

[0054] combined with figure 1 ~attached Image 6 A description of specific embodiments is carried out.

Embodiment approach 1

[0055] Embodiment 1: The fixing unit 1 is mainly composed of a housing assembly 11 , a plug assembly 12 and a quick fixing assembly 13 . The latch assembly 12 is inserted into the latch hole 1110 in the housing body 111 , and the initial position is fixed by the set screw 123 , the compression spring 124 and the steel ball 125 . The pin shaft body 132 of the quick fixing assembly 13 is inserted into the pin shaft hole 116 in the housing body 111 , and is axially fixed by the No. 1 washer 136 and the No. 1 shaft retaining ring 137 . The expansion connecting unit 2 is directly connected to the expansion screw 119 of the housing body 111 of the fixing unit 1 through the expansion inner thread 25 . The composition of the space station manipulator compression seat conversion device is as follows figure 1 shown.

Embodiment approach 2

[0056] Embodiment 2: The housing assembly 11 is mainly composed of a housing body 111 , a visual indicator 114 , a universal armrest base 113 and a locking screw 112 . The visual indicator 114 and the universal armrest base 113 are connected to the housing body 111 by screws, and the locking screw 112 is installed in the No. 1 threaded hole 1111 of the housing body 111 . The casing body 111 has a casing anti-drifting hole 118. When the astronaut takes the fixed unit 1 out of the cabin, the anti-drifting rope needs to be hung in the casing anti-drifting hole 118. The composition of the casing assembly 11 is shown in the appendix. figure 2 and attached image 3 shown.

Abstract

The present invention provides a space station manipulator pressing seat conversion device, which includes a fixing unit and an expansion connecting unit. The fixing unit includes a casing assembly, a plug assembly and a quick fixing assembly. For the compression seat of the robotic arm of the space station, a latch assembly is installed on the front side of the shell assembly, and a quick fixing assembly is installed on the left side. A space station manipulator pressing seat conversion device according to the present invention has an integrated structure, which is consistent with the actual working conditions of the space station manipulator joints, has no additional motion conversion links, reduces the transmission error, and is conducive to obtaining High detection accuracy; the work is divided into two parts: fixed and extended. The work of the fixed unit can be completed with only one clamping. After the clamping is in place, it is automatically carried out. The extravehicular operation is simple and reliable, which greatly reduces the extravehicular space of the astronauts. Work time and reduce work intensity.

Description

technical field [0001] The invention belongs to the application field of space stations, and in particular relates to a conversion device for a manipulator arm pressing seat of a space station. Background technique [0002] The space station consists of three cabins, of which the core cabin manipulator, the quadrant II flexible solar wing and the IV quadrant flexible solar wing are deployed, leaving a large number of compression seats and available space. After the two flexible solar wings on the Wentian capsule, the robotic arm of the Wentian capsule and the two flexible solar wings on the Mengtian capsule are deployed, a large amount of compression seats and available space are also left. Converting these compression seats so that they can be used for tasks such as the fixation of large-scale equipment and on-orbit construction is of great significance for improving the extravehicular service capability of the large platform of the space station, expanding the extravehicul...
