The detection assembly 103 includes a bottom plate, a detection frame 104, and an independent detection block 105. The lower surface of the bottom plate is attached to and detachably connected to the upper surface of the panel. A circle of detection frames 104 is pre - arranged on the four - peripheral edges of the upper surface of the bottom plate;

[0035] The outer edge of the mold tire assembly 102 is pre-set to have the same proportional dimensions as the outer edge of the aircraft panel after milling (according to the outer edge contour of the aircraft panel designed in the milling drawing, and using existing mature technologies to detect the outer edge contour of the mold tire assembly 102 until it is qualified). The lower surface of the mold tire assembly 102 is attached to the upper surface of the bottom plate. The upper surface of the bottom plate is larger than the lower surface of the mold tire assembly 102. The inner edge of the detection frame 104 is formed by equally spacing and expanding based on the outer edge of the mold tire assembly 102, and a first detection gap is formed between the inner edge of the detection frame 104 and the outer edge of the mold tire assembly 102.

[0036] The quick positioning blocks 117 are a number of blocks with uniform thickness. The detection frame 104 includes a plurality of frame detection blocks. The inner edge contour of each frame detection block matches the outer side wall surface at the bottom of the quick positioning block 117, and the inner side wall surface at the bottom of the quick positioning block 117 matches the outer edge contour of the mold tire assembly 102.

[0037] When multiple quick positioning blocks 117 are placed in the first detection gaps in the front, rear, left, and right directions of the support platform 100, the gap values at any position of the first detection gap are equal, and the lower surface of the mold tire assembly 102 can be connected and locked with the upper surface of the bottom plate of the detection assembly 103.

[0038] Through the cooperative design of multiple quick positioning blocks 117 and the multiple frame detection blocks of the detection frame 104, the quick positioning of the mold tire assembly 102 and the detection assembly 103 is realized, so as to ensure that a first detection gap with equal distance is quickly formed between the inner edge of the detection frame 104 and the outer edge of the mold tire assembly 102.

[0039] As Figures 1 to 3 shown, in this embodiment, at least one independent detection block 105 is pre-set on the upper surface of the bottom plate located inside the detection frame 104. A through groove for cooperating with the corresponding independent detection block 105 is pre-opened on the mold tire assembly 102. The independent detection block 105 extends into the through groove of the mold tire assembly 102, and a second detection gap with equal distance is formed between the independent detection block 105 and the through groove of the mold tire assembly 102.

[0040] The inner wall surface contour of each second detection gap corresponds to the outer contour of the bottom of one quick positioning block 117 for matching.

[0041] As Figure 3 shown, in this embodiment, the height of the quick positioning block 117 is higher than the height of the first detection gap, and the height of the quick positioning block 117 is the height of the second detection gap.

[0042] As Figures 1 to 3 shown, in this embodiment, the milling fixture for the aircraft panel further includes an auxiliary positioning frame. The auxiliary positioning frame includes a guiding slider 107, which is slidably arranged in an annular chute 106 on the upper surface of the support platform 100 and can be locked. A first hydraulic telescopic rod 108 is vertically connected to the upper surface of the guiding slider 107. The top of the first hydraulic telescopic rod 108 is rotatably connected to one end of a second hydraulic telescopic rod 109 (for example, a rotating shaft) and can be locked through a linkage joint locking structure 111 (the linkage joint locking structure 111 is a mature existing technology. For example, an electromagnetic lock. When the electromagnetic lock is energized, the rotating shaft cannot move actively, thus realizing locking. The installation method of the electromagnetic lock is a mature existing technology and will not be elaborated here. The same applies hereinafter). The other end of the second hydraulic telescopic rod 109 is rotatably connected to one end of a third hydraulic telescopic rod 110 and can be locked through another linkage joint locking structure 111. The other end of the third hydraulic telescopic rod 110 is movably connected to a clamping bottom plate 113 through a bearing 112;

[0043] One end of the clamping bottom plate 113 is detachably connected with a quick positioning block 117. A linear guiding groove 114 is formed on the bottom surface of the clamping bottom plate 113. A connecting block is slidably arranged in the linear guiding groove 114. A movable clamping block 118 is fixedly connected to the bottom surface of the connecting block. A fixed clamping block 119 is fixedly connected to the bottom surface of the other end of the clamping bottom plate 113. A threaded channel is formed in the fixed clamping block 119. A rotating screw 120 is threadedly connected in the threaded channel of the fixed clamping block 119. One end of the rotating screw 120 extends out of the threaded channel and is fixedly connected with a rotating handle 115. The other end of the rotating screw 120 extends out of the threaded channel and is rotatably connected to the movable clamping block 118; wherein, the quick positioning block 117, the movable clamping block 118 and the fixed clamping block 119 are all located on the bottom side of the clamping bottom plate 113.

[0044] Through the design of the auxiliary positioning frame, during the installation process, it is avoided that the operator needs to keep the quick positioning block 117 in a lifted state all the time before the quick positioning block 117 is placed into the detection gap, and the placing posture can also be well adjusted, making the installation process time-saving and labor-saving for the operator.

[0045] As Figures 1 to 3 shown, in this embodiment, a first threaded connection hole is formed at one end of the clamping bottom plate 113, and a second threaded connection hole is formed at the top of the quick positioning block 117. The first threaded connection hole and the second threaded connection hole are connected to each other through a bolt 116, and the top surface of the quick positioning block 117 is in contact with the bottom surface of the clamping bottom plate 113.

[0046] Through the cooperative design of the first threaded connection hole, the second threaded connection hole, and the bolt 116, it is ensured that the quick positioning block 117 can be detachably connected to the clamping bottom plate 113, so as to facilitate the replacement of different quick positioning blocks 117 according to the different internal contours of the first detection gap (the outer contours of the bottoms of different individual quick positioning blocks 117 are different).

[0047] As Figures 1 to 3 shown, in this embodiment, an electromagnetic lock is provided between the annular sliding groove 106 and the guiding slider 107.

[0048] Through the design of providing an electromagnetic lock between the annular sliding groove 106 and the guiding slider 107, it is ensured that the guiding slider 107 can not only slide within the annular sliding groove 106, but also be locked in place after sliding to a predetermined position.

[0049] In addition, scale marks are provided on the edge of the annular sliding groove 106, and each frame detection block has a model mark. Each frame detection block with a model mark corresponds to a quick positioning block 117. The detachable connection can all adopt the cooperation connection of a screw and a nut. The specific connection position can be determined according to the actual installation situation to avoid mutual interference between parts.

[0050] Working principle:

[0051] Realize the quick fixation between the tire mold assembly 102 and the detection assembly 103:

[0052] According to the design of the drawing of the aircraft panel milling, the outer contour of the tire mold assembly 102 is set in advance to be the same as and qualified for the contour of the aircraft panel after milling on the drawing (obtained through the detection by existing technical means);

[0053] The theoretical basis for installation: The inner contour of the detection frame 104 is formed by equidistant expansion (qualified through the detection by existing technical means), which can ensure that the first detection gaps at any gap positions between the tire mold assembly 102 and the detection frame 104 are equidistant;

[0054] Place multiple quick positioning blocks 117 in the first detection gaps in the front, rear, left, and right directions of the support platform 100, ensuring that in the actual installation process, the first detection gaps at any gap positions can also be equidistant. At this time, fix the tire mold assembly 102 and the detection assembly 103 (fixed by screws and nuts), and take out the quick positioning blocks 117.

[0055] Quick determination of the qualification of the aircraft panel during milling:

[0056] Place the un-milled aircraft panel on the upper surface of the mold assembly 102 and fix it (existing and mature negative pressure adsorption technology can be adopted, refer to the patent literature in the background technology). Then, mill the aircraft panel. Finally, after the milling of the aircraft panel is completed, place the quick positioning block 117 into the first detection gap and the second detection gap again. If the quick positioning block 117 cannot be directly placed into the first detection gap and the second detection gap, the milled aircraft panel is still not processed in place; if the quick positioning block 117 can be placed into the first detection gap and the second detection gap, fix the quick positioning block 117, and then cooperate with a feeler gauge to detect the distance between the quick positioning block 117 and the outer contour of the aircraft panel, and determine whether the milled aircraft panel is within the pre-specified qualified range (the pre-specified qualified range is obtained according to the requirements of the aircraft panel milling drawing). If it is within the pre-specified qualified range, it is qualified.

[0057] Movement and locking of the quick positioning block 117: First, select a suitable quick positioning block 117 (not installed) according to the model mark of the border detection block; adjust the position of the first hydraulic telescopic rod 108 in the annular sliding groove 106, so that the clamping bottom plate 113 moves away from the aircraft panel milling tooling as the first hydraulic telescopic rod 108 rotates. Place the suitable quick positioning block 117 on an existing and mature liftable trolley, and move it to directly below the installation end of the clamping bottom plate 113 at this time. The liftable trolley rises to a suitable position, and the operator installs the quick positioning block 117 at the installation end (one side of the clamping bottom plate 113) of the clamping bottom plate 113; then rotate the guiding slider 107 again (a rotating handle can be set outside the lower section of the first hydraulic telescopic rod 108 for convenient rotation), until the un-installed quick positioning block 117 is directly above the position where the quick positioning block 117 should be installed (adjusted by the cooperation of the second hydraulic telescopic rod 109 and the third hydraulic telescopic rod 110). Then lower the first hydraulic telescopic rod 108 until the quick positioning block 117 is installed at the installation position of the first detection gap. Then rotate the bolt 116 so that a part of the external thread of the bolt 116 is exposed, so that the clamping bottom plate 113 can rotate around the bolt 116, thereby adjusting the angle of the clamping bottom plate 113 so that the border detection block corresponding to the detection border 104 is located between the quick positioning block 117 and the movable clamping block 118. Then rotate the handle 115 to make the movable clamping block 118 contract and clamp the border detection block corresponding to the detection border 104, and finally tighten the bolt 116. Repeat the above process to install the second, third, and even the fourth quick positioning block 117 to prepare for the quick fixation between the mold assembly 102 and the detection assembly 103 in the future.

[0058] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
