Problems solved by technology

The logistics supply of the International Space Station is very expensive and difficult compared with any previous human natural exploration activities. The logistics problems faced by establishing bases on the moon and Mars in the future will be more severe, especially in response to emergencies, which are delayed by ground support The loss will be immeasurable

Embodiment 1

[0044] Such as Figure 1 ~ Figure 3 As shown, a push rod pressing device of this embodiment includes a worktable movable restraint seat 1 and a restraint head 2, and the restraint head 2 is installed on the workbench movable restraint seat 1, and the restraint head 2 The constraint direction is arranged at an angle to the installation direction of the movable constraint seat 1 of the workbench, figure 1 The direction of the middle arrow a is the constraint direction of the constraint head 2, and the direction of the arrow b is the installation direction of the movable constraint seat 1 of the workbench; the movable constraint seat 1 of the workbench includes the main support of the constraint seat, the tightening handle 12 and the movable block 13 The main support of the constraint seat is provided with an assembly through hole, and the movable stopper 13 can be embedded in the assembly through hole of the main support of the constraint seat so that it can rotate along the cir...

Embodiment 2

[0052] On the basis of Example 1, such as Figure 4 As shown, the constraining head 2 of this embodiment includes a constraining head main support, a rotating push handle 23, an elastic member, and a sliding constraining head 25. A pre-compression channel is formed in the constraining head main support, and the pre-compression channel The two ends are the operation end and the pre-compression end respectively, and the said rotary propulsion handle 23 is threadedly connected in the operation end of the said pre-compression channel and elastically connected with the sliding constraint head 25 through an elastic member; A circle of annular steps is provided on the inner sidewall (the said annular step can be a square annular step, also can be a circular annular step, or be other polygonal annular steps), and the outer sidewall of the sliding constraint head 25 is provided with an annular platform Shoulder 251, the annular shoulder 251 abuts on the annular step, and the free end o...

Embodiment 3

[0058] Such as Figure 5 and Figure 6 As shown, a positioning assembly of this embodiment includes the push rod pressing device described in Embodiment 1 or Embodiment 2, and also includes an angle gauge 3, and the bottom of the angle gauge 3 is provided with a guide pin post 31, so that A rubber strip 32 is provided on the inner side of the angle gauge 3 . The rubber strip on the angle gauge can protect the load equipment while ensuring a certain friction. Positioning on the table is possible by setting on the guide pin post on the angle gauge.

[0059] Such as Figure 5 and Figure 6As shown, a preferred solution of this embodiment is that the inner surface of the angle gauge 3 is provided with a plurality of through grooves with the top through and the bottom closed, and rubber strips 32 are embedded in the grooves. The top of 3 is fixed with the briquetting block 33 that compresses described rubber bar 32. A pressing block can be used to compress and fix the rubber ...

Abstract

The invention relates to a push rod pressing device, a positioning assembly and a positioning device. The push rod pressing device includes a workbench movable restraint seat and a restraint head. The restraint head is installed on the workbench movable restraint seat. The installation direction of the movable restraint seat of the table is arranged at an angle; the movable restraint seat of the workbench includes the main support of the restraint seat, the tightening handle and the movable stopper. The main support of the restraint seat is provided with an assembly through hole, and the movable stopper can The rotating one is embedded in the assembly through hole of the main support of the constraint seat, and the movable block is provided with radially arranged handle sliding grooves, and the tightening handle is installed in the handle sliding grooves and can slide along the handle sliding grooves. The workbench movable restraint seat and restraint head arranged at an angle are used to fix the restraint head at a suitable position on the workbench through the workbench movable restraint seat, and provide pre-tightening force to the load equipment, and then use the restraint head to generate friction with the load equipment And ensure that the constraints on the load equipment are fixed.

Description

technical field [0001] The invention relates to the related technical field of equipment positioning in a microgravity space, in particular to a push rod pressing device, a positioning assembly and a positioning device. Background technique [0002] With the development of manned spaceflight technology, establishing a long-term habitable and working environment in outer space has become the focus of human spaceflight. The logistics supply of the International Space Station is very expensive and difficult compared with any previous human natural exploration activities. The logistics problems faced by establishing bases on the moon and Mars in the future will be more severe, especially in response to emergencies, which are delayed by ground support The loss will be immeasurable. Therefore, taking into account the initiative of astronauts, by providing personnel with a series of tools and technical support, enhancing the ability of independent maintenance and support of facili...
