Problems solved by technology

However, how to make full use of the shape characteristics and stiffness characteristics of stretching parts such as semi-rigid thin-walled tubes, use semi-rigid thin-walled tubes and other stretching parts in parallel, and realize different semi-rigid thin-walled tubes by continuously positioning and clamping support devices The mutual fixation of such stretching parts, thereby improving the overall stiffness performance of stretching parts such as multiple semi-rigid thin-walled tubes, needs to be solved urgently

Embodiment 1

[0029] Such as Figure 1 to Figure 12 As shown, a positioning and pressing support device includes a clamping mechanism 1 and a driving and guiding mechanism 2 . The clamping mechanism 1 is a mechanism for clamping and connecting the extension part 3 , which can slide on the guide rail 21 of the driving and guiding mechanism 2 and is constrained by the shape of the guide rail 21 . The driving and guiding mechanism 2 can drive the position of the clamping mechanism 1 on the guide rail 21 .

[0030] The clamping mechanism 1 is located inside the guide rail 21 of the driving and guiding mechanism 2, and the clamping mechanism 1 and the guide rail 21 are in a relative moving relationship; the stretching part 3 can stretch and move in the clamping mechanism 1 in the unclamped state during the stretching process. Constituting stretching movement constraints, the clamping mechanism 1 in the clamped state forms a clamping connection with the stretching part 3 .

[0031] The clamping...

Abstract

The invention relates to a positioning and pressing supporting device, which comprises a clamping mechanism (1), a driving and guiding mechanism (2); the clamping mechanism (1) is located inside the guide rail (21) of the driving and guiding mechanism (2), and The mechanism (1) slides relatively in the guide rail (21); the clamping mechanism (1) includes several clamping units. During the stretching process, it is stretched in the opened clamping mechanism (1), and when the clamping unit moves out from the guide rail (21), the clamping unit clamps the stretching part (3). The invention realizes links such as driving release of the clamping device, fixed connection of the thin-walled pipe, etc., and realizes pressing and locking of predetermined distances between stretching parts such as the stretched thin-walled pipe.

Description

technical field [0001] The invention belongs to the field of machinery and relates to a positioning and pressing support device. Background technique [0002] For the field of space deployment mechanisms, due to the limitation of the envelope size of the overall load that can be carried by the launch vehicle, it is necessary to use mechanisms and related technologies with foldable or deformable characteristics to achieve the goal of sending specific loads into space. With the increasing demand for large-scale loads in space, the existing stretching mechanisms that work alone are gradually difficult to meet the demand for high stiffness. [0003] In order to make the load smaller in size and larger in size, rigid or semi-rigid material deployment technologies such as hinged folding devices and truss rod deployment devices have been developed, as well as inflatable airbags and shape memory materials with certain flexibility characteristics. unfolding technique. This kind of ...
