Embodiment 1

[0054] combined with figure 1 ~ attached Image 6 A specific embodiment will be described.

Embodiment approach 1

[0055] Embodiment 1: The fixing unit 1 is mainly composed of a housing component 11 , a latch component 12 and a fast fixing component 13 . The latch assembly 12 is inserted into the latch hole 1110 in the shell body 111 , and the initial position is fixed by a set screw 123 , a compression spring 124 and a 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 a No. 1 washer 136 and a No. 1 shaft circlip 137 . The expansion connection unit 2 is directly connected to the expansion screw 119 of the housing body 111 of the fixing unit 1 through the expansion internal thread 25 . The composition of the clamping seat conversion device of the space station manipulator is as attached 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 locking screws 112 . The visual sign 114 and the universal armrest base 113 are connected to the housing body 111 through screws, and the locking screw 112 is installed in the No. 1 threaded hole 1111 of the housing body 111 . The shell body 111 has a shell anti-float hole 118. When an astronaut goes out of the cabin and carries the fixed unit 1 out of the cabin, the anti-float rope needs to be hung in the shell anti-float hole 118. The composition of the shell assembly 11 is as follows: figure 2 And attached image 3 shown.

Abstract

The invention provides a space station mechanical arm pressing seat conversion device which comprises a fixing unit and an expansion connecting unit, the fixing unit comprises a shell assembly, a plug pin assembly and a rapid fixing assembly, the top of the shell assembly is installed on the expansion connecting unit, the bottom of the shell assembly is installed on a space station mechanical arm pressing seat, and the front side of the shell assembly is installed on the plug pin assembly. The left side is mounted to the quick fixing assembly. According to the space station mechanical arm pressing seat conversion device, the device is of an integrated structure, the actual use working condition of the device is consistent with that of a space station mechanical arm joint, no additional motion conversion link exists, the transmission error is reduced, and high detection precision can be obtained easily; the operation is divided into two parts of work of fixing and expanding, the work of the fixing unit can be completed only through one-time clamping, automatic proceeding is achieved after clamping is in place, the outboard operation is simple and reliable, the outboard operation time of astronauts is greatly shortened, and the operation intensity is reduced.

Description

technical field [0001] The invention belongs to the application field of space stations, and in particular relates to a space station mechanical arm pressing seat conversion device. Background technique [0002] The space station consists of three cabins. After the core cabin mechanical arm, II quadrant flexible solar wing and IV quadrant flexible solar wing are deployed, a large number of compact seats and available space are left. 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 compressed seats and usable space are also left. Converting these compression seats so that they can be used for tasks such as fixing large 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 extravehicular operating platform, and verifying the o...
