Description

Technical Field

[0002] In the satellite structural assembly process, there is still a significant amount of manual trimming on the sides of structural panels, accounting for approximately 30% of the entire assembly cycle. This trimming is characterized by poor precision, low efficiency, and high labor intensity for workers, severely impacting the main assembly progress. Current trimming methods require two operators working together. The structural panel is placed on a platform, one operator holds the panel while another experienced operator uses a steel file to trim it. After trimming, a trial assembly is performed on-board.

[0021] In this invention, the milling unit 2 is used to mill the side of the structural plate. It moves in two horizontal orthogonal directions through the milling slider 23 and the manual displacement table 25. The milling unit 2 is set on the side of the long side of the rectangular table of the work platform 1.

[0022] The milling unit 2 includes a guide rail mounting plate 21, a guide rail 22, a milling slider 23, a milling table 24, a manual displacement table 25, a pneumatic drill fixing bracket 26, a locking bracket 27, a pneumatic drill 28, a drive device 29, and a dust collection device 210.

The clamping unit 41 also includes a rubber pad 418; a rubber pad 418 is attached to the end of each cylinder 417 to prevent damage to the surface of the structural plate to be repaired.

The first movable clamping unit 42 is set on the right side of the milling table 24, and the second movable clamping unit 43 and the third movable clamping unit 44 are set on the left side.

[0029] The milling and finishing process of this invention is as follows: Before milling the structural plate, adjust the position of the lifting block 2 on the work platform 1 according to the size and surface characteristics of the structural plate. The lifting block 12 supports the structural plate while avoiding protrusions on the surface of the structural plate. Place the structural plate on the lifting block 12 and adjust the structural plate so that the edge of the structural plate to be milled is placed on one side of the guide rail 22 and parallel to the guide rail 22. Make the adjacent edge of the edge to be milled really close to the reference surface on the positioning unit 3 to complete the positioning of the structural plate.

[0030] Loosen the locking handle 414 on the fixed clamping unit 41, rotate the locking cylinder arm 414 to apply pressure to the clamping area of ​​the structural plate by the cylinder 417, move the No. 1 moving clamping unit 42 to the rightmost side of the guide rail 22, clamp the No. 2 clamping unit 43 and the No. 3 clamping unit 44 in the left side area of ​​the structural plate, and at the same time insert the pin at the end of the knob plunger 423 into the hole of the guide rail mounting plate 21 to complete the clamping of the structural plate. If the length of the edge to be milled on the structural plate is less than 1.5 meters, only the right fixed clamping unit 41 needs to be used to clamp the right side of the structural plate, and the left side of the structural plate needs to be clamped using the No. 2 moving clamping unit 43. If the structural plate is longer than 1.5 meters, the right fixed clamping unit 41 is still used to clamp the right side of the structural plate, the No. 2 moving clamping unit 43 is used to clamp the right side of the structural plate at a position 1.5 meters away from the right edge of the structural plate, and the No. 3 moving clamping unit 44 is used to clamp the leftmost side of the structural plate. The No. 1 moving clamping unit 42 is moved to the rightmost side of the guide rail 22. When the milling unit 2 moves from right to left to mill, the No. 1 moving clamping unit 42 and the No. 2 moving clamping unit 43 are simultaneously moved to the right intermittently to ensure that the structural plate is reliably clamped within a 1.5-meter range of the milling area.

[0031] After the structural plate is clamped, it can be milled. Before milling, the milling unit 2 is moved to the far right of the structural plate. The air drill 28 is adjusted by the manual displacement table 25 so that the end mill clamped at the end of the air drill contacts the edge of the structural plate to be milled, thus completing the tool setting before milling. Then, the milling unit 2 is moved to the far right of the guide rail 22. The feed rate is adjusted by the manual displacement table 25. The air drill 28 and the dust collection device 210 are turned on. The handwheel 294 is turned so that the milling unit 2 moves to the left at a constant speed to mill the structural plate. After milling to the left side of the structural plate, the milling unit 2 is moved to the right side of the structural plate again and the feed rate is adjusted by the manual displacement table 25. The structural plate is milled again. The above operation is repeated until the structural plate is milled to the desired position.

[0032] After the structural plate milling is completed, turn off the air drill 28 and the dust collection device 210, release the pressure of all cylinders 417, pull out the knob plunger 423, move the milling unit 2, the No. 2 moving clamping unit 43 and the No. 3 moving clamping unit 44 to the leftmost side of the guide rail 22, move the No. 1 moving clamping unit 42 to the rightmost side of the guide rail, tighten the locking handle 414, and lock the cylinder arm 415 to complete the entire milling process.
