Description

Technical Field

[0001] This application relates to the technical field of satellite production equipment, and in particular to an automated satellite assembly platform. Background Technology

[0002] In satellite production and assembly, the platform frame is usually placed on the workbench first, and then the workers assemble the components one by one onto the platform frame to complete the assembly of the equipment and components carried on the satellite platform.

[0003] The existing workbench is a fixed structure and cannot be raised or lowered. Furthermore, the fixing mechanism of the fixed platform frame can only fix a platform frame of a fixed size. When it is necessary to assemble a different platform frame, a different work platform and fixing mechanism are required. There is a defect that the fixing mechanism on the same work platform cannot fix platform frames of different sizes. Summary of the Invention

[0004] To make the fixed mechanisms on the work platform universal, this application provides a satellite automated assembly platform.

[0005] The satellite automated sliding assembly platform provided in this application adopts the following technical solution:

[0006] An automated satellite assembly platform includes a platform body, with casters mounted on the four corners of the bottom of the platform body. An electric telescopic rod is provided on one side of each caster. One end of the electric telescopic rod is fixed to the platform body, and the other end of the electric telescopic rod is fixed to a support plate. A rotary support platform is provided on the platform body, and a drive assembly for driving the rotary support platform to rotate is installed on the platform body.

[0007] A satellite platform frame is provided on the slewing support platform. The satellite platform frame includes a satellite docking frame and a slewing support docking frame. Multiple support rods are fixed between the satellite docking frame and the slewing support docking frame. Multiple fixing components are provided on the slewing support platform. The multiple fixing components are evenly arranged along the circumference of the slewing support platform.

[0008] The fixing component includes a fixing plate and an abutment plate. The fixing plate is fixed to the rotary support platform. The abutment plate is located on the side of the fixing plate near the rotary support docking frame. A first spring is fixed between the fixing plate and the abutment plate. Under the action of the first spring, the abutment plate abuts against the side wall of the rotary support docking frame.

[0009] By adopting the above technical solution, when installing the satellite platform frame, the slewing support docking frame of the satellite platform frame is placed on the slewing support platform, so that the abutment plate of the fixing component is pressed against the slewing support docking frame under the action of the first spring. Due to the setting of the first spring, even if the slewing support docking frame is enlarged or reduced, the abutment plate can still be pressed against the slewing support docking frame under the action of the first spring. The electric telescopic rod can adjust the overall height of the platform body.

[0010] Optionally, a base plate is fixed to the bottom of the abutment plate, an installation groove is provided on the upper surface of the rotary support platform, the base plate is located in the installation groove and is slidably connected to the installation groove, and the bottom of the rotary support docking frame is in contact with the base plate.

[0011] By adopting the above technical solution, when the rotary support docking frame is tightened, the abutment plate will move along the axis of the first spring. When the abutment plate moves, the base plate slides along the length of the mounting groove, thereby increasing the stability of the abutment plate.

[0012] Optionally, a first limiting post is connected to the base plate, and a limiting hole is provided on the rotary support docking frame for the first limiting post to be inserted into, the limiting hole penetrating the rotary support docking frame.

[0013] By adopting the above technical solution, after the abutment plate tightens the slewing support docking frame, the first limiting post is also inserted into the limiting hole. The limiting post limits the slewing support docking frame, reducing the possibility of the slewing support docking frame rotating.

[0014] Optionally, a groove is provided on the upper surface of the base plate, and a slider is slidably connected in the groove. The first limiting post is fixed on the slider, and a second spring is fixed between the slider and the groove wall near the abutment plate.

[0015] By adopting the above technical solution, the slider can move along the length of the groove, which makes it easy for the first limiting post to align with the limiting hole, thus facilitating the installation of the rotary support docking frame.

[0016] Optionally, a connecting rod is provided above the fixing plate. The connecting rod includes a first connecting rod and a second connecting rod. One end of the first connecting rod has a connecting hole, and one end of the second connecting rod is inserted into the connecting hole. A third spring is provided in the connecting hole. One end of the third spring is fixed to the second connecting rod, and the other end of the third spring is fixed to the end of the connecting hole away from the second connecting rod. A locking bolt is provided at the end of the first connecting rod away from the second connecting rod. The locking bolt passes through the first connecting rod and is threadedly connected to the fixing plate. The second connecting rod contacts the upper surface of the rotary support docking frame.

[0017] By adopting the above technical solution, after the abutment plate of the fixing component presses against the rotary support docking frame, the first connecting rod and the second connecting rod are rotated so that the bottom of the second connecting rod contacts the rotary support docking frame. Then, the locking bolts are tightened to fix the first connecting rod and the second connecting rod. The second connecting rod can reduce the possibility of the rotary support docking frame swaying up and down.

[0018] Optionally, a second limiting post is provided at the end of the second connecting rod away from the first connecting rod. The second limiting post passes through the second connecting rod, and a pull block is fixed at the top of the second limiting post. A connecting spring is fixed between the pull block and the second connecting rod. The connecting spring is sleeved with the second limiting post, and the second limiting post is inserted into the limiting hole.

[0019] By adopting the above technical solution, the second limiting post is inserted into the limiting hole under the action of the connecting spring. When disassembling the rotary support docking frame, first pull the pull block to pull the second limiting post out of the limiting hole, then loosen the locking bolt, rotate the first connecting rod and the second connecting rod to disengage the second connecting rod from the rotary support docking frame.

[0020] Optionally, the drive assembly includes a gear and a gear ring, the gear ring being fixed to the periphery of the rotary support platform and meshing with the gear, and a motor being fixed to the bottom of the platform body, the output shaft of the motor being fixed to the gear.

[0021] By adopting the above technical solution, the motor drives the gear to rotate, the gear drives the gear ring to rotate, and the gear ring drives the rotary support platform to rotate.

[0022] Optionally, a protective cover is installed on the platform body, which encloses the gear and the gear ring inside.

[0023] By adopting the above technical solution, the protective cover protects the gears and gear rings.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. When installing the satellite platform frame, place the slewing support docking frame of the satellite platform frame on the slewing support platform, so that the abutment plate of the fixed component abuts against the slewing support docking frame under the action of the first spring. Due to the setting of the first spring, even if the slewing support docking frame becomes larger or smaller, the abutment plate can still abut against the slewing support docking frame under the action of the first spring. The electric telescopic rod can adjust the overall height of the platform body.

[0026] 2. When the slewing support docking frame is tightened, the abutment plate will move along the axis of the first spring. When the abutment plate moves, the base plate slides along the length of the mounting groove, thereby increasing the stability of the abutment plate.

[0027] 3. After the abutment plate tightens the slewing support docking frame, the first limiting post is also inserted into the limiting hole. The limiting post limits the slewing support docking frame, reducing the possibility of the slewing support docking frame rotating. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0035] This application discloses an automated satellite assembly platform. (Refer to...) Figure 1 , Figure 2 and Figure 3 The satellite automated assembly platform includes a platform body 1. Each of the four corners of the bottom of the platform body 1 is equipped with a movable wheel 11. Each movable wheel 11 is provided with an electric telescopic rod 12 on one side. One end of the electric telescopic rod 12 is fixed to the bottom of the platform body 1, and a support plate 121 is fixed to the end of the electric telescopic rod 12 away from the platform body 1.

[0036] When the platform body 1 needs to be moved, the moving wheels 11 contact the ground, and the support plate 121 detaches from the ground. When the platform body 1 does not need to be moved, the electric telescopic rod 12 is activated, causing the support plate 121 to support the ground, and the moving wheels 11 to detach from the ground. The electric telescopic rod 12 can adjust the height of the platform body 1.

[0037] A slewing support platform 2 is mounted on the platform body 1. The slewing support platform 2 is rotatably connected to the platform body 1 and can rotate on the platform body 1. A drive assembly 3 is mounted on the platform body 1 to drive the slewing support platform 2 to rotate.

[0038] A satellite platform frame 4 is provided on the slewing support platform 2. The satellite platform frame 4 includes a satellite docking frame 41, support rods 42 and a slewing support docking frame 43. The satellite docking frame 41 is located above the slewing support docking frame 43, and multiple support rods 42 are fixed between the satellite docking frame 41 and the slewing support docking frame 43.

[0039] The slewing support docking frame 43 is located on the upper surface of the slewing support platform 2. The slewing support platform 2 is provided with a fixing mechanism 5, which fixes the slewing support docking frame 43.

[0040] Reference Figure 3 , Figure 4 and Figure 5 The fixing mechanism 5 includes four fixing components 51, which are evenly arranged circumferentially on the rotary support platform 2. Each fixing component 51 includes a fixing plate 511 and an abutment plate 512. The bottom of the fixing plate 511 is fixed to the upper surface of the rotary support platform 2, and the abutment plate 512 is located on the side of the fixing plate 511 near the rotary support docking frame 43. A first spring 513 is fixed between the abutment plate 512 and the fixing plate 511. Under the action of the first spring 513, the abutment plate 512 abuts against the side wall of the rotary support docking frame 43.

[0041] A base plate 52 is fixed to the bottom of the abutment plate 512. A mounting groove 521 is provided on the upper surface of the rotary support platform 2. The base plate 52 is located in the mounting groove 521, and the upper surface of the base plate 52 is flush with the upper surface of the rotary support platform 2. The base plate 52 can slide along the length of the mounting groove 521.

[0042] A first limiting post 522 is connected to the upper surface of the base plate 52. A sliding groove 523 is formed on the upper surface of the base plate 52, and a slider 524 is disposed in the sliding groove 523. The slider 524 is slidably connected to the sliding groove 523, and the upper surface of the slider 524 is flush with the upper surface of the base plate 52. The first limiting post 522 is fixed to the upper surface of the slider 524.

[0043] A second spring 525 is installed in the slide groove 523. One end of the second spring 525 is fixed to the slider 524, and the other end is fixed to the groove wall of the slide groove 523 near the abutment plate 512. A limit hole 431 is provided on the rotary support docking frame 43. The limit hole 431 is vertically oriented and passes through the rotary support docking frame 43. The first limit post 522 is inserted into the limit hole 431. When there is an error in the position of the limit hole 431 on the rotary support docking frame 43, the slider 524 can be slid to adjust the position of the first limit post 522, so that the first limit post 522 is inserted into the limit hole 431. The first limit post 522 can reduce the possibility of the rotary support docking frame 43 rotating.

[0044] When the satellite platform frame 4 is installed onto the slewing support platform 2, the limiting hole 431 of the slewing support docking frame 43 is inserted and engaged with the corresponding first limiting post 522, so that the bottom of the slewing support docking frame 43 contacts the upper surface of the base plate 52 and the upper surface of the slewing support platform 2. Under the joint action of the abutment plates 512 of the four fixing components 51, the slewing support docking frame 43 is limited and fixed.

[0045] Each fixing plate 511 in each fixing assembly 51 is provided with a connecting rod 6, which includes a first connecting rod 61 and a second connecting rod 62, and the first connecting rod 61 and the second connecting rod 62 are sleeved together. The end of the first connecting rod 61 near the second connecting rod 62 has a connecting hole 611, and a third spring 612 is provided in the connecting hole 611. One end of the second connecting rod 62 extends into the connecting hole 611 and is fixed to one end of the third spring 612. The end of the third spring 612 away from the second connecting rod 62 is fixed to the end of the connecting hole 611 away from the second connecting rod 62.

[0046] A locking bolt 63 is provided at the end of the first connecting rod 61 away from the second connecting rod 62. The locking bolt 63 passes through the first connecting rod 61 and is threadedly connected to the fixing plate 511. A second limiting post 621 is provided at the end of the second connecting rod 62 away from the first connecting rod 61. The second limiting post 621 passes through the second connecting rod 62. A pull block 622 is fixed to the top of the second connecting rod 62, and the bottom of the second limiting post 621 is inserted into the limiting hole 431. Both the first connecting rod 61 and the second connecting rod 62 are square tubes. The bottom of the second connecting tube is in contact with the upper surface of the rotary support docking frame 43.

[0047] A connecting spring 623 is fixed between the pull block 622 and the second connecting rod 62, and the connecting spring 623 is sleeved with the second limiting post 621. After the abutment plate 512 presses against the rotary support docking frame 43, the first connecting rod 61 and the second connecting rod 62 are rotated, pulling the pull block 622 to compress the connecting spring 623, aligning the second limiting post 621 with the corresponding limiting hole 431. After releasing the pull block 622, the second limiting post 621 is inserted into the limiting hole 431 under the action of the connecting spring 623, and then the locking bolt 63 is tightened. In the normal state, the bottom of the second limiting post 621 is lower than the bottom of the second connecting rod 62.

[0048] Reference Figure 1 and Figure 2 The drive assembly 3 includes a gear 31 and a gear ring 32. The gear ring 32 is fixed to the periphery of the rotary support platform 2. The gear 31 meshes with the gear ring 32. A motor 33 is fixed to the bottom of the platform body 1. The output shaft of the motor 33 is fixed to the gear 31. The motor 33 drives the gear 31 to rotate, and the gear 31 drives the gear ring 32 and the rotary support platform 2 to rotate. A protective cover 21 is fixed on the platform body 1. The protective cover 21 covers the gear 31 and the gear ring 32 inside, providing protection for the gear 31 and the gear ring 32.

[0049] The implementation principle of the satellite automated assembly platform in this application embodiment is as follows: When installing the satellite platform frame 4, the slewing support docking frame 43 is first placed on the slewing support platform 2, so that the limiting hole 431 on the slewing support docking frame 43 is aligned with the first limiting post 522 on the base plate 52 and the first limiting post 522 is inserted into the limiting hole 431. The abutment plates 512 of the four fixing components 51 abut against the slewing support docking frame 43 under the action of their respective first springs 513.

[0050] Then rotate the first connecting rod 61 and the second connecting rod 62 on the fixed plate 511 so that the second limiting post 621 on the second connecting rod 62 is aligned with the corresponding limiting hole 431, so that the second limiting post 621 is inserted into the limiting hole 431, and tighten the locking bolt 63.
