[0034] Embodiment 1

[0035] Referring to Figure 1 and Figure 2 The present embodiment is an optional embodiment of the present application, which discloses an automatic dimpling device for a flap skin, comprising a rack 1, an XY linkage adjusting assembly is arranged on one side of the rack 1, the XY linkage adjusting assembly comprises a base 4 and a sliding plate 5, wherein the base 4 is arranged on the rack 1, two X-direction sliding rails 6 parallel to each other are arranged on the base 4 along the length direction of the base 4, a sliding block 7 is slidably arranged on each of the X-direction sliding rails 6, and the upper and lower sides of the sliding plate 5 are connected with each of the sliding blocks 7 respectively, so as to realize the sliding connection between the base 4 and the sliding plate 5.

[0042] A displacement sensor 15 is arranged on the bottom surface of the counterbore motor 11, which can detect the position of the drill bit in real time, so as to realize the automatic detection and automatic control of the counterbore depth, and is beneficial to improve the quality and processing efficiency of the counterbore processing;

[0043] Meanwhile, a rotating motor 3 and an inclination adjusting assembly are arranged on the rack 1, wherein the inclination adjusting assembly comprises two lifting columns 16, which are symmetrically arranged on the left and right sides of the support frame 2, and two second lifting slide rails 19 are arranged on the mutually opposite sides of the two lifting columns 16, and a lifting seat 17 is slidably connected with each second lifting slide rail 19; the two lifting seats 17 are in an L-shaped structure, and a reinforcing rib is arranged at the bottom of each lifting seat 17;

[0044] Two lifting columns 16 are further provided with lifting drive modules, the lifting drive module comprises a second lifting motor 20 and a second lifting screw 21, the second lifting motor 20 is arranged on the lifting column 16 and connected with the second lifting screw 21 through a shaft coupling; the second lifting screw 21 is arranged between two second lifting rails 19 and connected with the lifting seat 17 screw thread, thereby controlling the height of the lifting seat 17;

[0045] It should be pointed out that the two lifting columns 16 and the lifting seat 17 and the lifting drive module attached thereto are independently arranged and do not interfere with each other, so as to realize the separate adjustment of the height positions of the two lifting seats 17;

[0046] Two parallel compensation rails 22 are further arranged on the two lifting seats 17, each compensation rail 22 is arranged in a direction parallel to the X-direction rail 6, and an inclination adjusting seat is further arranged on the two lifting seats 17, the inclination adjusting seat comprises a sliding seat 1801 and a rotating seat 1802, wherein the sliding seat 1801 is connected with two compensation rails 22 on the same lifting seat 17 through a sliding block 7; a rotating lug plate is arranged on the top of the sliding seat 1801, and two rotating shafts are arranged on the two sides of the rotating seat 1802, and the two rotating shafts are inserted into the corresponding rotating lug plate;

[0048] Linear grating scales are arranged on the two lifting columns 16, which can quickly and accurately detect the height of the sliding seat 1801 and improve the control accuracy;

[0049] The supporting bracket 301 is further provided with a test piece station, which can verify the processing technology, and the formal piece is processed after the verification confirms that it does not meet the quality requirements, which is beneficial to improve the processing quality and reduce the production cost; meanwhile, a plurality of positioning holes are arranged on the supporting bracket 301, and the skin to be processed is also provided with positioning holes, the positioning holes are used to fix the skin to be processed and quickly position the position of the skin to be processed, thereby providing basic coordinate parameters for the subsequent processing operation.

[0051] Subsequently control the lifting drive module to control the support bracket 301 to the lowest position, and then control the dimple assembly to move to the dimple point position. The above adjustment can effectively avoid the interference between the dimple assembly and the skin to be processed during the adjustment process.

[0052] Subsequently, the two lifting seats 17 on both sides are controlled to rise according to the attitude requirements to control the height positions thereof. The height of the lifting seat 17 is detected by the linear grating ruler 23 during the adjustment process. Since the two lifting seats 17 are controlled separately, the final heights of the two lifting seats 17 can be equal or not equal.

[0053] If the heights of the two lifting seats 17 are equal, the support bracket 301 is always in a horizontal state. At this time, the rotation angle of the support bracket 301 can be controlled by the rotation of the rotating motor 3, and then the alignment of the machining point position on the skin and the cutter can be controlled.

[0054] If the heights of the two lifting seats 17 are not equal, the rotating seat 1802 will rotate due to the height difference between the two lifting seats 17 since the sliding seat 1801 and the rotating seat 1802 are in a hinged state. At this time, the rotating seat 1802 on one side rotates upward, and the rotating seat 1802 on the other side rotates downward. During the rotation process, the rotating seat 1802 pulls the sliding seat 1801 to slide on the compensation slide rail 22.

[0055] The inclination angle of the support bracket 301 can be accurately adjusted by controlling the distance difference between the two sliding seats 1801. In combination with the rotation of the rotating motor 3, the attitude adjustment of the curved skin can be realized.

[0056] Compared with the prior art, the above technical solution not only has a simple structure, but also improves the reliability and stability of the equipment.

[0057] Meanwhile, the present application also realizes the automatic adjustment of the skin attitude and the automatic control of the dimple, which is conducive to reducing the dimple difficulty and improving the dimple efficiency. The precision of the automatic adjustment is higher, and the position precision of the dimple can be effectively improved.
