DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] The polishing equipment for processing a super hemispherical fairing disclosed in the present invention is mainly applied to the existing polishing equipment for processing a super hemispherical fairing. During use, when the outer surface of the fairing is polished by a polishing wheel, debris generated during the polishing process is splashed to other positions of the fairing. The splashing of the debris can easily cause scratches on other positions of the fairing. The fairing is used in a satellite, and tiny defects will cause irreversible losses. Therefore, there are scenarios in which the existing polishing equipment has potential safety hazards during use.

[0037] Reference Figure 1-Figure 11 A polishing device for processing a super hemispherical fairing comprises a processing table 1, a directional adjustment component 2 is arranged above the processing table 1, and the directional adjustment component 2 comprises a directional sliding track 201, a directional movable slider 204 is slidably connected inside the directional sliding track 201, a through mounting hole 1 is opened on the top of the directional movable slider 204, a hydraulic cylinder 13 is fixedly connected inside the mounting hole 1, a motor frame 14 is fixedly connected to the output end of the hydraulic cylinder 13, a fitting collection component 11 is arranged on the outside of the motor frame 14, the fitting collection component 11 comprises an annular round rod 1101, and a deflection collar 1104 is sleeved on the outer wall of the annular round rod 1101 at equal distances, each deflection collar 1104 is fixedly connected to the outer wall of the motor frame 14 with a deflection pressure plate 1108, a plurality of deflection pressure plates 1108 are closed into a ring, and each deflection pressure plate 1108 faces the motor frame 1 4 are fixedly connected with sealing airbags 1103, the sealing airbags 1103 are partially located below the deflection pressure plate 1108, and the outer wall of the annular round rod 1101 located above each deflection pressure plate 1108 is fixedly connected with two fixing rods 1109, the outer walls of the two fixing rods 1109 facing downward are hingedly connected with hydraulic cylinder three 1117, the output end of the hydraulic cylinder three 1117 is hingedly connected to the top of the deflection pressure plate 1108, an air hole is opened on one side of the sealing airbag 1103, and an air pipe 1116 is fixedly connected inside the air hole, and an electromagnetic valve 1115 is connected to the outer wall of the air pipe 1116 through a flange, and the outer wall of the deflection ring 1104 away from the deflection pressure plate 1108 is fixedly connected with a follower limit plate 1106, and the side of the follower limit plate 1106 facing the motor frame 14 is fixedly connected with a sealing sheet 1105.

[0038] In a specific application scenario, when the driving motor 13 drives the polishing wheel 10 to polish the outer wall of the fairing, the hydraulic cylinder three 1117 is adjusted to drive the deflection pressure plate 1108 to press down, so that the sealing airbag 1103 is pressed on the outer wall of the fairing at the polishing position. The multiple sealing airbags 1103 cooperate with each other to squeeze and seal the polishing position of the polishing wheel 10, ensuring that the debris generated during the polishing process will not splash to other positions of the fairing and cause scratches. At the same time, during the polishing process, the collection pump 1114 is started, and the collection pump 1114 collects the debris generated by polishing through the collection hole 1102 as soon as possible, further eliminating the safety hazards caused by the splashing debris, improving the polishing effect of the fairing, and protecting the fairing.

[0039] Specifically, when the hydraulic cylinder 3 1117 drives the deflection pressure plate 1108 to press down, the deflection ring 1104 rotates accordingly, and the deflection ring 1104 drives the follow-up limit plate 1106 to move toward the motor frame 14. The sealing plates 1105 above each follow-up limit plate 1106 contact each other, thereby achieving sealing above the current polishing position of the fairing, avoiding debris from splashing to the outside, and improving the debris collection rate.

[0040] It should be noted that during the fairing polishing process, when the polishing wheel 10 moves under the adjustment of the directional adjustment assembly 2, since the fairing is a super-hemispherical structure, each sealing airbag 1103 squeezes and slides on the outer wall of the fairing, and the sealing ring formed by each sealing airbag 1103 always achieves a close seal on the outside of the polishing point of the polishing wheel 10, ensuring that the debris generated by polishing will not cause damage to other positions of the fairing.

[0044] Specifically, there is a geometric magnification relationship between the directional sliding track 201 and the cross-section of the fairing. During the polishing process of the fairing, the rotating motor 15 below drives the fairing to rotate 360°, and the adjusting cylinder 202 drives the directional movable slider 204 to slide in the directional sliding track 201. The two cooperate to achieve polishing processing at various positions on the outer surface of the fairing. At the same time, the degree of the cross-section of the directional sliding track 201 is greater than the degree of the cross-section of the fairing, which can ensure that the fairing is surrounded by the directional sliding track 201 in all directions, thereby improving the use value of the polishing equipment.

[0047] Specifically, when fixing the fairing, it is directly sleeved on the inner supporting arc surface, and then the cylinder three 2003 is adjusted to drive the positioning arc plate 2001 to move toward the periphery. During the movement, multiple positioning arc plates 2001 gradually contact the inner wall of the fairing, and the position of the fairing is adjusted, so that the center point of the fairing is gradually aligned with the rotating long axis 16, and the positioning of the fairing is quickly completed. After the positioning is completed, the vacuum pump 2006 is started, and the vacuum pump 2006 performs a vacuum operation through the vacuum adsorption hole 2004, so that the positioning arc plate 2001 vacuum adsorbs the inner wall of the fairing to complete the positioning and fixation, thereby ensuring that the fairing will not be displaced or fall off during the polishing process.

[0048] It should be noted that when squeezing between the positioning arc plate 2001 and the inner wall of the fairing, the pressure plate 2010 presses on the pressure sensor 2011. When the pressure on the pressure sensor 2011 reaches the specified value, the cylinder three 2003 stops running to avoid excessive squeezing causing the inner support of the fairing to rupture, protect the fairing, and improve the safety performance of the polishing equipment.

[0049] A polishing method for processing a super hemispherical fairing, using the polishing equipment for processing a super hemispherical fairing as described above, the polishing method comprises the following steps:

During the movement, multiple positioning arc plates 2001 gradually contact the inner wall of the fairing, and adjust the position of the fairing so that the center point of the fairing is gradually aligned with the rotation axis 16, and the positioning of the fairing is quickly completed. After the positioning is completed, start the vacuum pump 2006, and the vacuum pump 2006 performs a vacuum operation through the vacuum adsorption hole 2004, so that the positioning arc plate 2001 vacuum adsorbs the inner wall of the fairing to complete the positioning and fixing, and then adjust the cylinder two 19 to drive the outer limiting arc plate 18 to clamp and limit the outer wall of the fairing near the bottom end;

[0052] Step three: During the polishing process, adjust the hydraulic cylinder three 1117 to drive the deflection pressure plate 1108 to press down, so that the sealing airbag 1103 is pressed on the outer wall of the fairing at the polishing position.

The collection pump 1114 collects the debris generated by polishing through the collection hole 1102 as soon as possible, so as to further eliminate the safety hazards caused by the sputtering debris. After the polishing of the outer surface of the fairing is completed, it is removed to end the operation.
