[0027] like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, as a preferred embodiment of the present invention, the downward limiting movement component 5 includes a ratchet bar 501 embedded and fixed on the side wall of the support plate 105; a guide groove 502 is fixed on the fixed vertical plate 102, and a guide block 503 is slidably connected in the guide groove 502, and an engaging tooth 504 is fixed on one end of the guide block 503 close to the ratchet bar 501; a compression spring 2 505 and an L-shaped follower rod 506 are fixed at the other end of the meshing tooth 504, the compression spring 2 505 is located in the guide groove 502, and the end of the L-shaped follower rod 506 extends out of the fixed vertical plate 102; multiple fixed vertical plates 102 are further fixedly connected by a mouth-shaped reinforcement rib 111, and a concave moving rod 112 is slidably connected to the upper end of the mouth-shaped reinforcement rib 111, and multiple push rods 507 are fixed on the concave moving rod 112, and the push rod 507 cooperates with the L-shaped follower rod 506.

[0030] In the embodiment of the present invention, the lower end of the second vertical moving cavity 602 is connected to the lower end of the first vertical moving cavity 103 through the hard connecting pipe 601. When high pressure is generated in the second vertical moving cavity 602, high pressure is also generated in the first vertical moving cavity 103. The high pressure in the first vertical moving cavity 103 pushes the piston block 3 603 to move upward, and the piston block 3 603 drives the L-shaped limiting block 604 to move upward, so that the L-shaped limiting block 604 does not contact the concave moving rod 112; when negative pressure is generated in the second vertical moving cavity 602, negative pressure is also generated in the first vertical moving cavity 103. The negative pressure in the first vertical moving cavity 103 pulls the piston block The third 603 moves downward, and the piston block 3 603 drives the L-shaped limiting block 604 to move downward, thereby making the L-shaped limiting block 604 contact with the upper end of the concave moving rod 112, so that the L-shaped limiting block 604 limits the concave moving rod 112, avoiding the concave moving rod 112 to move accidentally when there is negative pressure in the vertical moving cavity 2 602, causing the downward movement restriction of the support plate 105 to be released and the piston block 104 and the support plate 105 to rush to the bottom, avoiding the aviation arc plate 7 from accidentally touching the concave moving rod 112 during processing, causing the support force of the aviation arc plate 7 to disappear, thereby improving the safety of the processing of the aviation arc plate 7.

[0033] The above embodiment of the present invention provides an aviation arc plate processing tool. When in use, the aviation arc plate processing tool can be fixed on various machine tools to assist in the processing of the aviation arc plate 7. The aviation arc plate 7 is placed on the upper end of multiple support plates 105. The air source device injects high-pressure air into the lower ends of multiple vertical movable cavities 103 through the pipeline assembly 2. The lower end of the vertical movable cavity 2 602 is connected to the lower end of the vertical movable cavity 103 through the hard connecting pipe 601. When high pressure is generated in the vertical movable cavity 2 602, high pressure is also generated in the vertical movable cavity 103. The high pressure in the vertical movable cavity 103 pushes the piston block 3 603 to move upward, and the piston block 3 603 drives the L-shaped limit block 604 to move upward, thereby making the L-shaped limit block 604 move upward. The control block 604 does not contact the concave moving rod 112. Under the action of the high pressure at the lower end of the vertical moving cavity 103, the piston block 104 can be driven to move upward, and the piston block 104 drives the support plate 105 to move upward, so that the upper end of the support plate 105 contacts the lower end of the aviation arc plate 7 and supports the aviation arc plate 7. Since the lower ends of multiple vertical moving cavities 103 are connected, the air pressure in the multiple vertical moving cavities 103 is the same, so that the upper ends of the multiple support plates 105 can all contact the aviation arc plate 7, so that the connection line of the upper ends of the multiple support plates 105 is consistent with the contour of the lower end surface of the aviation arc plate 7, and the compression spring 2 505 pushes the guide block 503 to move, and the guide block 503 drives the meshing teeth 504 and the ratchet bar 501 The air source device generates negative pressure at the lower ends of the plurality of vertical moving cavities 103 through the pipeline assembly 2, and pulls the piston block 104 downward under the action of the negative pressure suction force, thereby limiting the upward movement of the support plate 105. Then, under the negative pressure at the lower end of the vertical moving cavity 103 and the limiting action of the downward limiting moving assembly 5, the up and down movement of the support plate 105 is limited, so that the contour formed by the connection of the upper ends of the plurality of support plates 105 is fixed. When negative pressure is generated in the vertical moving cavity 2 602, negative pressure is also generated in the vertical moving cavity 1 103. The negative pressure in the vertical moving cavity 1 103 pulls the piston block 3 603 to move downward, and the piston block 3 603 drives the L-shaped limiting block 604 to move downward. The limiting protrusion 606 on the L-shaped limiting block 604 is inserted into the limiting tooth groove 605 of the concave moving rod 112, thereby limiting the movement of the concave moving rod 112, and avoiding the concave moving rod 112 to move accidentally due to negative pressure in the vertical moving cavity 602, so that the downward movement restriction of the support plate 105 is released and the piston block 104 and the support plate 105 rush to the bottom, avoiding the disappearance of the supporting force of the aviation arc plate 7 due to the concave moving rod 112 moving accidentally during the processing of the aviation arc plate 7, thereby improving the safety of the processing of the aviation arc plate 7.
