Description

Technical Field

[0001] The invention belongs to the field of compression and release mechanisms, and in particular relates to a W-shaped belt-type compression and release mechanism for a spacecraft. Background Art

[0002] Due to the launch cost, the overall weight of the spacecraft is required to be controlled, and the product is required to be lightweight. A certain spacecraft needs to use multiple clamping and releasing mechanisms for clamping. The traditional clamping rod type clamping and releasing mechanism has a large load-bearing capacity, but the weight does not meet the requirements. Some clamping and releasing mechanisms require multiple use, but due to their light weight and small clamping force, they cannot meet the requirements of light weight and large load at the same time. Therefore, it is urgent to develop a new clamping and releasing mechanism. Summary of the invention

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0033] A spacecraft W-type belt-type clamping release mechanism, such as Figures 1 to 7As shown, it includes a pre-tightening cap 1, a pre-tightening seat 2, a No. 1 clamping support block 3, a No. 2 clamping support block 4, a No. 3 clamping support block 5, a clamping seat 6, a clamping swing rod 7, a clamping linkage rope 8, a pull ring 9, a fine-tuning screw 10, a compression spring fixing shaft 11, a No. 1 compression spring 12, a No. 2 compression spring 13, a compression linkage rope head 14, a wedge-shaped pre-tightening block 16, a compression belt pressure piece 17, a pre-tightening spring 20, a swing rod gasket 21, and a swing rod rotating shaft 22. The pre-tightening block 16, the pre-tightening spring 20 and the pre-tightening cap 1 are installed above the pre-tightening seat 2, and the pre-tightening cap 1 cooperates with the pre-tightening block 16 to prevent the W-shaped compression belt from rebounding; the pre-tightening cap 1 is used to connect the W-type clamping belt 15 on the outside. The lower part of the pre-tightening seat 2 is connected to the clamping seat 6 through the No. 2 part 19, the No. 1 part 18 and several clamping support blocks. The clamping swing rod 7 is symmetrically installed on the upper part of the clamping seat 6. The pull rings 9 are symmetrically installed on both sides of the lower part of the clamping seat 6. Each pull ring 9 is connected to a clamping swing rod 7 through a clamping linkage rope 8, so that the clamping linkage rope 8 can drive the clamping swing rod 7 to rotate under the action of external force. The No. 1 compression spring 12 and the No. 2 compression spring 13 are installed in the middle of the clamping seat 6. The No. 1 compression spring 12 and the No. 2 compression spring 13 are located below the clamping swing rod 7 and are used to apply an upward force to the clamping swing rod 7. The W-type belt-type clamping release mechanism of the present invention has a doubled clamping force compared to the traditional belt-type clamping release mechanism. The belt-type clamping release mechanism linkage mode is used to drive multiple clamping release mechanisms to release simultaneously through one linkage mechanism. The optimized structural design ensures that the clamping force is doubled without increasing the weight.

[0034] In this embodiment, the clamping support block includes a clamping support block No. 1 3, a clamping support block No. 2 4, and a clamping support block No. 3 5 which are arranged in sequence from top to bottom. The preload seat 2, the part No. 2 19 and the clamping support block No. 1 3 are fixedly connected together by screws, and the clamping support block No. 1 3 and the clamping support block No. 2 4 are matched with each other through conical surfaces (specifically, a plurality of conical grooves are provided at the edge below the clamping support block No. 1 3, and a plurality of conical protrusions are provided at the edge below the clamping support block No. 2 4, which are inserted into the conical grooves to connect and limit the clamping support block No. 1 3 and the clamping support block No. 2 4, and the conical surface matching methods hereinafter are the same as this method); the clamping support block No. 2 4, the part No. 1 18 and the clamping support block No. 3 5 are fixedly connected together in sequence by screws; the clamping support block No. 3 5 and the clamping seat 6 are matched with each other through conical surfaces.

[0035] The W-shaped clamping belt 15 covers the exterior of the preload cap 1, the preload seat 2, the No. 1 clamping support block 3, the No. 2 clamping support block 4, the No. 3 clamping support block 5, the No. 1 part 18, and the No. 2 part 19.

[0036] A compression belt pressing piece 17 is installed on the top of the preload cap 1 by screws. The compression belt pressing piece 17 is used to fix the W-shaped compression belt 15, thereby ensuring the overall stability of the mechanism. According to actual needs, in order to meet the distance requirements between the No. 1 part 18 and the No. 2 part 19, the height of the No. 1 compression support block 3 and the No. 2 compression support block 4 can be adjusted. In order to ensure that the overall compression height remains unchanged, the thickness of the No. 3 compression support block 5 can be adjusted. This makes the compression release mechanism more versatile.

[0037] In this embodiment, a rocker arm rotating shaft 22 is installed on the upper part of the clamping seat 6, and two clamping rocker arms 7 are installed in the middle part of the rocker arm rotating shaft 22, and the directions of the two clamping rocker arms 7 are symmetrical. A rocker arm gasket 21 is provided between each clamping rocker arm 7 and the clamping seat 6, and the rocker arm gasket 21 is sleeved on the outside of the rocker arm rotating shaft 22 to prevent the clamping rocker arm 7 from directly rubbing against the clamping seat 6 when rotating, thereby reducing friction and extending the service life of the mechanism.

[0038] The clamping rocker arm 7 includes a rocker arm body 71, a connecting portion 72, a rotating portion 73, a connecting block 74 and a limiting groove 75. The rocker arm body 71 is an arc-shaped structure. The lower end of the rocker arm body 71 is fixedly connected to the connecting portion 72. The connecting portion 72 and the clamping linkage rope 8 are detachable and installed. The upper end of the rocker arm body 71 is fixedly connected to the rotating portion 73. The rotating portion 73 is provided with a mounting hole, and the mounting hole is fixedly connected to the clamping seat 6 through an axle pin. A limiting groove 75 is provided on the top of the rotating portion 73, and a connecting block 74 is provided on one side. The connecting block 74 is clamped with the clamping seat 6 to limit the swing angle of the rocker arm body 71.

[0039] Preferably, the connecting portion 72 is a semicircular groove with an opening at the bottom, and the inner diameter of the semicircular groove gradually decreases from top to bottom. The connecting portion 72 is used to place the compression linkage rope head 14, which is a spherical or truncated cone or conical structure. The bottom of the compression linkage rope head 14 is fixedly connected to the compression linkage rope 8 (welded or integrated structure). This connection method is convenient for adjusting, replacing and maintaining the compression linkage rope 8.

[0040] In one or more embodiments, a compression spring fixing shaft 11 is installed in the middle of the compression seat 6, and an installation groove is provided in the middle of the compression spring fixing shaft 11, and a No. 1 compression spring 12 and a No. 2 compression spring 13 are installed in the installation groove. The No. 1 compression spring 12 and the No. 2 compression spring 13 have the same structure, and both sides of the No. 1 compression spring 12 and the No. 2 compression spring 13 extend out of the compression spring fixing shaft 11 and are located directly below the compression swing rod 7. When the compression swing rod 7 is subjected to external force (when the W-type compression belt 15 is compressed), the compression swing rod 7 can be directly pressed on the No. 1 compression spring 12 and the No. 2 compression spring 13. When the W-type compression belt 15 is released after compression, the staff loosens the compression linkage rope 8, and the No. 1 compression spring 12 and the No. 2 compression spring 13 restore their deformation, and the compression swing rod 7 bounces back to the initial position.

[0041] The clamping seat 6 is an integrated axially symmetrical structure, with a mounting platform on the top of the clamping seat 6, which cooperates with the conical surface of the No. 3 clamping support block 5. A clamping groove 61 and an axial hole 62 are provided in the middle of the clamping seat 6, and a clamping groove 64 and a pin hole 63 are provided on the top. The clamping groove 61, the axial hole 62, the pin hole 63 and the clamping groove 64 are all connected, which greatly reduces the weight of the clamping seat 6; the axial hole 62 is used to install the compression spring fixing shaft 11, and the pin hole 63 is movably connected with the mounting hole of the clamping swing rod 7 through the axial pin, and the clamping groove 61 is used to pass through the clamping swing rod 7, and the slot 64 is used to pass through the connecting block 74. Specifically, the bottom of the cylindrical end of the W-type clamping belt 15 passes through the slot 64 and is located inside the clamping seat 6. When the clamping swing rod 7 rotates under the action of external force, the connecting block 74 of the clamping swing rod 7 passes through the slot 64 and is located outside the clamping seat 6. At this time, the limiting groove 75 contacts the cylindrical end of the W-type clamping belt 15 until it fits, and the cylindrical end of the W-type clamping belt 15 is limited in the slot 64 of the clamping seat 6. By utilizing the space inside the clamping seat 6, the occupied space of the mechanism is greatly reduced, the volume of the mechanism is reduced, and the structure is simplified.

[0042] In one or more embodiments, the pull ring 9 is installed at the bottom of the clamping seat 6 by a fine-tuning screw 10, so that the height of the pull ring 9 can be fine-tuned according to actual usage, making the clamping release mechanism more versatile and able to adapt to different working conditions.

[0043] The pre-tightening block 16 is a wedge-shaped pre-tightening block, and the pre-tightening cap 1 cooperates with the slope surface of the wedge-shaped pre-tightening block 16 .

[0044] Preferably, the pre-tightening block 16 includes a pre-tightening shaft 161, a guide block 162 and a mounting screw 163. The pre-tightening shaft 162 is mounted on the pre-tightening seat 2 by means of screws. The pre-tightening shaft 162 is externally movably sleeved with the guide block 162 and the pre-tightening spring 20, and the pre-tightening spring 20 is located on one side of the guide block 162. The guide block 162 is a wedge-shaped guide block, and the other side of the guide block 162 is fixedly connected to the mounting screw 163. When the mounting screw 163 is rotated, the guide block 162 can be driven to move along the pre-tightening shaft 161, thereby changing the elastic force of the pre-tightening spring 20; when the mounting screw 163 is screwed outward, the guide block 162 will return to its original path under the action of the elastic force of the pre-tightening spring 20; an inclined surface is provided inside the pre-tightening cap 1, and the inclined surface inside the pre-tightening cap 1 fits with the slope surface of the guide block 162 (the two can slide relative to each other under the action of external force), and the outside of the pre-tightening cap 1 is clamped with the pre-tightening seat 2 to prevent the pre-tightening cap 1 from falling off.

[0045] The working principle of a spacecraft W-type belt-type clamping and releasing mechanism is as follows:

[0046] The pressing seat 6 is mounted to the outer mounting plate of the star body by screws. Figure 1 As shown, the W-type compression belt 15 is in a free state, the W-type compression belt 15 and the compression release mechanism are connected by screws, and the first part 18 and the second part 19 are in an uncompressed state. Figure 3 As shown, during compression, the cylindrical ends of the W-type compression belt 15 are simultaneously pressed into the slot 64 of the compression seat 6, and then the compression linkage rope 8 is tightened to rotate the compression swing rod 7 until the compression swing rod 7 fits with the W-type compression belt 15, and the W-type compression belt 15 is restricted in the slot 64 of the compression seat 6. The preload cap 1 is pulled up by the compression loading tool to drive the W-type compression belt 15 to be stretched to the predetermined load. Then the mounting screw 163 of the wedge-shaped preload block 16 is rotated to push the wedge-shaped preload block 16 to move inside the preload cap 1, and the position of the preload cap 1 is limited to ensure that the W-type compression belt does not rebound. The distance between the No. 1 part 18 and the No. 2 part 19 can be adjusted by increasing or decreasing the height of the No. 1 compression support block 3 and the No. 2 compression support block 4. Multiple compression release mechanisms are connected to a release assembly through a linkage rope, and the number of cutters is reduced through a one-to-many method, thereby achieving the purpose of weight reduction. Compared with the single-sided compression belt with small bearing capacity and difficulty in increasing the bearing capacity, the W-type compression belt and its structural optimization design can double the bearing capacity while keeping the overall weight unchanged; it can meet the compression requirements of spacecraft with medium compression force but high requirements for weight reduction.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
