Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to a box-type floating mechanism. Background Technology

[0002] With the rapid development of aerospace projects, the requirements for testing efficiency, accuracy, and safety in the mass production of satellites have significantly increased.

[0003] In the current satellite manufacturing field, satellites are typically moved horizontally by placing them on satellite support fixtures and then using a hoisting structure via a gantry truss. However, existing hoisting structures require floating structures, necessitating extremely precise alignment when docking the hoisting structure with the satellite support fixtures. This places extremely high demands on the skills and experience of the operators, significantly increases preparation time and operational complexity, and even minor alignment deviations can lead to docking failure or even collision and damage to the precision interfaces of the satellite or support fixtures. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a box-type floating mechanism.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A box-type floating mechanism includes a box body, on which a first floating plate that can slide horizontally along the X-axis is provided, and on the first floating plate a second floating plate that can slide horizontally along the Y-axis is provided, and on the second floating plate a mounting column for connecting a lifting structure is rotated. The box body is provided with a first fixing unit and a second fixing unit. The first fixing unit abuts against both sides of the first floating plate so that the first floating plate is centrally positioned on the box body along the X-axis direction. The second fixing unit abuts against both sides of the second floating plate so that the second floating plate is centrally positioned on the box body along the Y-axis direction.

[0006] Preferably, a first positioning unit is inserted into the housing, and a second positioning unit is inserted into the bottom of the second floating plate. The first and second positioning units have elastically set positioning ends. The side of the first floating plate forms a first positioning groove for the positioning end of the first positioning unit to be inserted into, and the top of the first floating plate forms a second positioning groove for the positioning end of the second positioning unit to be inserted into. Through the above improvements, in order to ensure that the first and second fixed units retract before floating positioning begins, the first and second floating plates deviate from the center position due to their own weight or tilt. Therefore, the first and second positioning units, along with the first and second positioning grooves respectively, provide a certain lateral resistance to the first and second floating plates, ensuring the stability of the first and second floating plates.

[0007] Preferably, a roller is provided on the positioning end, and the first positioning groove and the second positioning groove are arranged in an arc shape. With the above improvements, when the floating mechanism is started, the roller, together with the arc-shaped first positioning groove and the second positioning groove, can convert sliding friction into rolling friction, significantly reducing motion resistance, making the floating process smoother, and improving centering, which is conducive to smoother adaptive adjustment of the mechanism during hoisting and docking.

[0008] Preferably, the mounting column is provided with an anti-rotation block, and the second floating plate is provided with limit blocks on both sides. The anti-rotation block abuts against the limit plate to restrict the rotation of the mounting column. Through the above improvements, the structure provides a clear rotation limit for the mounting column and the lifting structure connected to it, and prevents the mechanism from being twisted due to accidental excessive rotation of the mounting column during hoisting or docking. It also enhances the controllability and safety of the entire floating mechanism during the movement process, and ensures the stability and reliability of satellite handling operations.

[0009] Preferably, a third positioning unit is inserted into the mounting column, and the third positioning unit abuts against the anti-rotation block. Through the above improvements, the rotation stroke of the mounting column can be adjusted by adjusting the extension distance of the third positioning unit.

[0010] Preferably, the ends of the first positioning unit and the second positioning unit are connected by connecting threads, and the housing and the second floating plate are connected by connecting holes that connect with the connecting threads. Through the above improvements, the ease of installation of the first positioning unit and the second positioning unit is enhanced, and the adjustment of the extension distance of the first positioning unit and the second positioning unit is made easier.

[0011] Preferably, the first positioning unit and the second positioning unit are plunger springs. Through the above improvements, the elastic preload built into the plunger springs can provide stable and adaptive lateral constraint forces for the first floating plate and the second floating plate.

[0012] Preferably, the floating stroke of the first floating plate and the second floating plate is ±100mm, and the rotation angle of the mounting column is ±2°. Through the above improvements, the convenience of hoisting and positioning is enhanced.

[0013] Preferably, the moving ends of the first fixing unit and the second fixing unit are provided with abutment blocks. Through the above improvements, the long-term squeezing and positioning can be avoided from causing the first floating plate and the second floating plate to become unsmooth, while ensuring the reliability of fixing the first floating plate and the second floating plate.

[0014] Preferably, the housing is provided with a first slide rail assembly, the first floating plate is disposed on the slide rail assembly, and the first floating plate is provided with a second slide rail assembly, and the second floating plate is disposed on the second slide rail assembly. Through the above improvements, the stability of the first floating plate and the second floating plate during the sliding process is greatly increased.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: A first floating plate that can slide horizontally along the X-axis is installed on the box body, and a second floating plate that can slide horizontally along the Y-axis is installed on the first floating plate. An installation column for connecting the lifting structure is mounted on the second floating plate. A first fixing unit and a second fixing unit are installed on the box body. The first fixing unit abuts against both sides of the first floating plate, so that the first floating plate is centered on the box body along the X-axis. The second fixing unit abuts against both sides of the second floating plate, so that the second floating plate is centered on the box body along the Y-axis. In the initial state, the actuating ends of the first and second fixing units in the X and Y directions extend, fixing the first and second floating plates in the middle position of the box-type floating mechanism, thus centering the installation column. When work is required, the first and second fixing units in the X and Y directions actuate, allowing the installation column to float in both directions via the first and second floating plates. After lifting is completed, the actuating ends of the first and second fixing units in the X and Y directions extend again, pushing the installation column back to the middle position. The middle position is the preset standard position of the satellite support fixture, effectively reducing the alignment accuracy requirements and improving the safety and efficiency of the docking operation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0019] like Figure 1-5 As shown, a box-type floating mechanism includes a box body 1, a first floating plate 2 that can slide horizontally along the X-axis is provided on the box body 1, a second floating plate 3 that can slide horizontally along the Y-axis is provided on the first floating plate 2, and an installation column 4 for connecting a lifting structure is provided on the second floating plate 3.

[0020] Specifically, the housing 1 is provided with a first fixing unit 5 and a second fixing unit 6. The first fixing unit 5 abuts against both sides of the first floating plate 2 so that the first floating plate 2 is centrally positioned on the housing 1 along the X-axis direction. The second fixing unit 6 abuts against both sides of the second floating plate 3 so that the second floating plate 3 is centrally positioned on the housing 1 along the Y-axis direction.

[0021] In the initial state, the actuating ends of the first fixing unit 5 and the second fixing unit 6 in the X and Y directions extend, fixing the first floating plate 2 and the second floating plate 3 in the middle position of the box-type floating mechanism, so that the mounting column 4 is centered. When work is required, the first fixing unit 5 and the second fixing unit 6 in the X and Y directions move, and the mounting column 4 can float in two directions through the first floating plate 2 and the second floating plate 3. After the hoisting is completed, the actuating ends of the first fixing unit 5 and the second fixing unit 6 in the X and Y directions extend again, pushing the mounting column 4 back to the middle position. The middle position is the preset standard position of the satellite support fixture, which effectively reduces the alignment accuracy requirements and improves the safety and efficiency of docking operations.

[0022] In addition, a first positioning unit 1.1 is inserted on the housing 1, and a second positioning unit 1.2 is inserted at the bottom of the second floating plate 3. The first positioning unit 1.1 and the second positioning unit 1.2 have positioning ends that are elastically set. The side of the first floating plate 2 forms a first positioning groove 1.3 for the positioning end of the first positioning unit 1.1 to be inserted, and the top of the first floating plate 2 forms a second positioning groove 1.4 for the positioning end of the second positioning unit 1.2 to be inserted.

[0023] To ensure that the first fixed unit 5 and the second fixed unit 6 retract before floating positioning begins, the first floating plate 2 and the second floating plate 3 deviate from the center position due to their own weight or tilt. Therefore, the first positioning unit 1.1 and the second positioning unit 1.2 cooperate with the first positioning groove 1.3 and the second positioning groove 1.4 respectively to provide a certain lateral resistance to the first floating plate 2 and the second floating plate 3, so as to ensure the stability of the first floating plate 2 and the second floating plate 3.

[0024] Among them, a roller 1.5 is provided on the positioning end, and the first positioning groove 1.3 and the second positioning groove 1.4 are arranged in an arc shape. Through the above improvements, when the floating mechanism is started, the roller 1.5, together with the arc-shaped first positioning groove 1.3 and the second positioning groove 1.4, can convert sliding friction into rolling friction, significantly reducing motion resistance, making the floating process smoother, and improving centering, which is conducive to smoother adaptive adjustment of the mechanism during hoisting and docking.

[0025] Preferably, the ends of the first positioning unit 1.1 and the second positioning unit 1.2 are provided with connecting threads 3.1, and the housing 1 and the second floating plate 3 are provided with connecting holes 3.2 that connect with the connecting threads 3.1, which improves the ease of installation of the first positioning unit 1.1 and the second positioning unit 1.2, and makes it easier to adjust the extension distance of the first positioning unit 1.1 and the second positioning unit 1.2.

[0026] Preferably, the first positioning unit 1.1 and the second positioning unit 1.2 are plunger springs. The elastic preload built into the plunger springs can provide a stable and adaptive lateral constraint force for the first floating plate 2 and the second floating plate 3.

[0027] Preferably, the floating stroke of the first floating plate 2 and the second floating plate 3 is ±100mm, thereby improving the convenience of hoisting and positioning.

[0028] Preferably, the moving ends of the first fixing unit 5 and the second fixing unit 6 are provided with abutment blocks 3.3 to avoid long-term squeezing and positioning from causing problems to the first floating plate 2 and the second floating plate 3, while ensuring the reliability of fixing the first floating plate 2 and the second floating plate 3.

[0029] Preferably, the housing 1 is provided with a first slide rail assembly 4.1, the first floating plate 2 is provided on the slide rail assembly, and the first floating plate 2 is provided with a second slide rail assembly 4.2, and the second floating plate 3 is provided on the second slide rail assembly 4.2, which greatly increases the stability of the first floating plate 2 and the second floating plate 3 during the sliding process.

[0030] like Figure 1-5As shown, as a further explanation of the embodiment of the mounting column 4, the mounting column 4 is provided with an anti-rotation block 2.1, and the second floating plate 3 is provided with limit blocks 2.2 on both sides. The anti-rotation block 2.1 abuts against the limit plate to restrict the rotation of the mounting column 4.

[0031] This structure provides clear rotation limits for the mounting column 4 and the lifting structure connected to it, and prevents the mechanism from being damaged by accidental excessive rotation of the mounting column 4 during hoisting or docking. It also enhances the controllability and safety of the entire floating mechanism during movement, ensuring the stability and reliability of satellite handling operations.

[0032] Furthermore, a third positioning unit 2.3 is inserted into the mounting column 4, and the third positioning unit 2.3 abuts against the anti-rotation block 2.1. The rotation stroke of the mounting column 4 can be adjusted by adjusting the extension distance of the third positioning unit 2.3.

[0033] The limiting blocks 2.2 are arranged in the same direction on both sides of the mounting column 4, and the limiting blocks 2.2 have adjustment grooves. The third positioning unit 2.3 is also a plunger spring. The third positioning unit 2.3 is inserted into the adjustment groove. The distance of the third positioning unit 2.3 extending out of the adjustment groove is adjusted to limit the rotation stroke of the mounting column 4.

[0034] Preferably, the rotation angle of the mounting column 4 is ±2°, which not only effectively reduces the alignment accuracy but also avoids damage to the lifting structure.

[0035] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
