[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] Please see Figures 1 to 8 This utility model provides a technical solution:

[0030] An automated cutting device for processing aircraft parts includes a worktable 1, clamping components 2, a negative pressure chip suction component 3, a cutting component 4, and a leveling component 5. The four clamping components 2 are movably mounted on the worktable 1 and arranged around its perimeter. The clamping components are used to clamp the workpiece to be processed. The cutting component 4 is located on the worktable 1 and above the clamping components 2. The cutting component 4 is used to process the workpiece.

[0031] The clamping assembly 2 includes a flexible clamping assembly 21, a locking assembly 22, and an electric cylinder 23. The flexible clamping assembly 21 is movably mounted on the worktable 1. By setting the flexible clamping assembly 21, it is convenient to clamp workpieces of different shapes. The locking assembly 22 is set on the flexible clamping assembly 21. The actuating end of the locking assembly 22 is in frictional engagement with the clamping part of the flexible clamping assembly 21. The frictional force between the actuating end of the locking assembly 22 and the clamping part of the flexible clamping assembly 21 fixes the flexible clamping assembly 21, making the flexible part of the flexible clamping assembly 21 rigid, which is convenient for clamping the workpiece. The electric cylinder 23 is set on the worktable 1, and its actuating end is in cooperation with the flexible clamping assembly 21.

[0032] The negative pressure chip suction component 3 is located on the worktable 1 and the clamping component 2 is located inside the negative pressure chip suction component 3; the negative pressure chip suction component 3 is used to absorb the chips during the processing of the workpiece.

[0033] The leveling component 5 is mounted on the worktable 1. The leveling component 5 is used to adjust the contact surface between the irregular workpiece to be processed and the worktable 1, so that it can be stably placed on the worktable 1.

[0034] In a preferred embodiment, the flexible clamping assembly 21 includes a mounting box 211, clamping rods 212, and spring I 213. The mounting box 211 is movably mounted on the worktable 1, and at least two clamping rods 212 are movably mounted inside the mounting groove on the side of the mounting box 211 via spring I 213. Thus, the clamping rods 212 can move linearly to clamp the workpiece to be processed.

[0035] In a preferred embodiment, the locking assembly 22 includes a slide groove 221, a slider 222, a return spring 223, a check assembly 224, and a pull rod 225. The mounting box 211 has the same number of slide grooves 221 as the clamping rods 212. The slider 222 is movably mounted inside the slide groove 221 via the return spring 223, facing the clamping rod 212. As the slider 222 moves closer to the clamping rod 212, the friction between the slider 222 and the clamping rod 212 restricts the movement of the clamping rod 212. The check assembly 224 is located on the side of the slider 222 and restricts its movement away from the clamping rod 212. The pull rod 225 passes through all the sliders 222 and is movably mounted on the mounting box 211. The pull rod 225 is fixedly connected to all the sliders 222. Pulling the pull rod 225 causes all the sliders 222 to move synchronously.

[0036] In a preferred embodiment, the check valve assembly 224 includes a stop groove 2240, a stop block 2241, a spring II 2242, and a push rod 2243. The mounting box 211 has a stop groove 2240 to accommodate the stop block 2241. The stop groove 2240 is located on the side of the slide groove 221. The stop block 2241 is movably mounted on the side of the slider 222 via the spring II 2242. When the end of the stop block 2241 is within the inner wall of the slide groove 221, the spring II 2242 is compressed, and the inner wall of the slide groove 221 blocks the stop block 2241, thus limiting its movement. 1. Moving away from slider 222, when stop 2241 is directly facing stop groove 2240, stop 2241 will move into stop groove 2240 under the action of spring force. At this time, the friction between slider 222 and clamping rod 212 can restrict the movement of clamping rod 212. Under the combined action of stop 2241 and stop groove 2240, slider 222 is restricted from moving away from clamping rod 212 under the action of return spring 223. Push rod 2243 is movably mounted on mounting box 211, and the actuating end of push rod 2243 is directly facing stop groove 2240. When it is necessary to release the friction lock, simply push push rod 2243 to make stop 2241 leave stop groove 2240. At this time, slider 222 will be released from lock under the action of return spring 223, which will move away from clamping rod 212.

[0037] In a preferred embodiment, the leveling assembly 5 includes a volute guide rail 51, a leveling block 52, and a screw 53. The worktable 1 is provided with the volute guide rail 51, and at least one leveling block 52 is movably fitted onto the volute guide rail 51. The volute guide rail 51 can drive the leveling block 52 to move to the lower part of the workpiece to be processed. The screw 53 is movably mounted on the leveling block 52. The height of the screw 53 is adjusted so that the lower part of the workpiece to be processed contacts the screw 53.

[0038] In a preferred embodiment, the negative pressure dust collection assembly 3 includes a rectangular frame 31, vacuum cleaners 32, and suction ports 33. The rectangular frame 31 is mounted on the workbench 1, the clamping assembly 2 is located inside the rectangular frame 31, and four vacuum cleaners 32 are located on the four sides of the rectangular frame 31 and communicate with the rectangular frame 31. The vacuum cleaners 32 provide negative pressure, and suction ports 33 are arrayed on the four sides inside the rectangular frame 31. The suction ports 33 are used to absorb dust.

[0039] In a preferred embodiment, the cutting assembly 4 includes an XYZR drive assembly 41 and a cutter 42. The XYZR linear drive assembly 41 is mounted on the worktable 1 and has a cutter 42 at the end of its execution.

[0040] As a preferred embodiment, the XYZR drive component 41 is a conventional technical means for those skilled in the art, and its principles and solutions will not be described in detail here.

[0041] The working principle of this utility model:

[0042] When using this device, first place the workpiece to be processed on the worktable 1, then start the leveling component 5, and move the leveling block 52 to the lower part of the workpiece through the vortex guide rail 51. Then adjust the height of the screw 53 so that the lower part of the workpiece contacts the screw 53.

[0043] Re-activate the electric cylinder 23 to push the flexible clamping assembly 21 toward the workpiece to be processed. The workpiece to be processed will squeeze the clamping rod 212 to cause it to extend and retract. When the clamping rod 212 is in complete contact with the workpiece to be processed, pull the pull rod 225 to push all the sliders 222. The friction between the sliders 222 and the clamping rod 212 can restrict the movement of the clamping rod 212. At this time, the stop block 2241 will pass through the stop block groove 2240. The stop block 2241 will move into the stop block groove 2240 under the action of the elastic force. Under the combined action of the stop block 2241 and the stop block groove 2240, the slider 222 can be restricted from moving away from the clamping rod 212 under the action of the return spring 223.

[0044] After clamping is completed, the cutting component 4 is started to process the workpiece. During processing, the negative pressure chip suction component 3 is provided with negative pressure by the vacuum cleaner 32, and then the chips are absorbed through the suction port 33.

[0045] After processing, when it is necessary to release the friction lock, simply push the push rod 2243 to make the stop block 2241 leave the stop block groove 2240. At this time, the slider 222 will be released by the action of the return spring 223, which will move away from the clamping rod 212. The clamping rod 212 will also be reset by the elastic force of the spring I 213.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
