[0022] 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.

[0023] Example 1: Please refer to Figures 1-5This utility model provides a technical solution: an efficient auxiliary tooling for cleaning aircraft engine fan blades, including a base 1 and blades 3. A vertical plate 2 is mounted on the base 1, and the blades 3 are movably mounted on the vertical plate 2. A cleaning mechanism is mounted on the vertical plate 2, and the cleaning mechanism is in contact with the surface of the blades 3. An infusion mechanism is mounted on the cleaning mechanism and is mounted on the base 1. A drive mechanism is mounted on the cleaning mechanism and is mounted on the vertical plate 2. A clamping and adjusting mechanism is mounted on the vertical plate 2 and is in contact with the blades 3. The cleaning mechanism includes a horizontally arranged guide rod 4, one end of which is mounted on the vertical plate 2, and the other end of which is mounted on a vertical rod 41. The vertical rod 41 is mounted on the base 1, and the guide rod 4 slides on the vertical plate 2. A sliding block 42 is installed, and a transmission block 62 is provided on one side of the sliding block 42. The upper ends of the sliding block 42 and the transmission block 62 are connected by a connecting plate 43. Two adapter boxes 44 are installed on the bottom side of the connecting plate 43. Multiple cleaning fluid nozzles 45 are installed on the inner ends of the two adapter boxes 44. The spraying direction of the multiple cleaning fluid nozzles 45 is adapted to the blade 3. Two mounting plates 46 are installed on the bottom side of the connecting plate 43. The mounting plates 46 are located on the inner ends of the corresponding adapter boxes 44 on the same side. A cleaning brush head 47 is installed on the inner end of the mounting plate (46). The surface of the cleaning brush head 47 is provided with bristles. The cleaning fluid nozzles 45 are used to spray cleaning fluid evenly onto the surface of the blade 3 to ensure that the cleaning fluid can fully cover the surface of the blade 3. The cleaning brush head 47 is used in conjunction with the cleaning solution to scrub the surface of the blade 3 to remove stains and grime. The cleaning brush head 47 is made of flexible material and has fine bristles on its surface to adapt to the cleaning needs of different blade 3 surfaces, while avoiding damage to the blade 3.

[0024] Furthermore, the infusion mechanism includes a storage container 5, which is mounted on a connecting plate 43. Flow control valves 51 are installed on both sides of the storage container 5. Each flow control valve 51 has a cleaning fluid pipe 52 at its outlet. The other end of the cleaning fluid pipe 52 is connected to multiple cleaning fluid nozzles 45 mounted on two adapter boxes 44 on the same side. A recovery box 53 is installed on the base 1, located directly below the blade 3. The recovery box 53 is sealed on all sides and open at its top. A filter screen 56 is installed at the top opening of the recovery box 53. A circulation pump 54 is installed on one side of the recovery box 53. A circulation pipe 55 is installed at the outlet of the circulation pump 54. The other end of the circulation pipe 55 is connected to the storage container 5. The cleaning fluid is transported from the storage container 5 to the cleaning fluid nozzles 45 via the cleaning fluid pipes 52. The flow control valves 51 are used to control the flow rate and direction of the cleaning fluid, ensuring that the cleaning fluid can act evenly on the surface of the blade 3. The circulation pump 54 is used to pump the used cleaning fluid back to the storage container 5 for recycling, so as to reduce resource waste. The filter screen 56 is used to filter out impurities and particles in the cleaning fluid, ensuring the cleanliness of the cleaning fluid and extending its service life.

[0025] Furthermore, the drive mechanism includes a lead screw 6, one end of which is rotatably mounted on the vertical plate 2, and a fixed rod 61 is rotatably mounted on the other end of the lead screw 6. The fixed rod 61 is mounted on the base 1, and a transmission block 62 is threaded onto the lead screw 6. A support plate 63 is mounted on one side of the vertical plate 2, and a motor 64 is mounted on the support plate 63. The output shaft of the motor 64 is coaxially connected to the lead screw 6. The motor 64 drives the lead screw 6 to rotate in both directions, thereby effectively driving the cleaning fluid nozzle 45 and the cleaning brush head 47 on the connecting plate 43 to reciprocate on the surface of the blade 3. At the same time, the device is equipped with a PLC control system component (not shown) to effectively and in real-time adjust and control the forward and reverse rotation of the motor 64, preventing the motor 64 from driving the lead screw 6 to idle and damaging the internal components of the motor 64.

[0026] Example 2: Based on Example 1, to facilitate the clamping and adjustment of the blade 3, a clamping and adjustment mechanism is arranged on the vertical plate 2. Specifically, it includes two electric telescopic rods 7, both of which are mounted on the vertical plate 2. A fixing bracket 71 is mounted on the piston rod of each of the two electric telescopic rods 7. The two fixing brackets 71 contact the upper and lower ends of the blade 3, respectively, and are used to fix the blade 3, ensuring the stability and positional accuracy of the blade 3 during the cleaning process. The fixing bracket 71 has an adjustable structure, which can adapt to blades 3 of different sizes and shapes, improving the versatility of the tooling. The remaining features are the same as in Example 1.

[0027] The working principle is as follows: When the surface of the blade 3 needs to be cleaned, the blade 3 is first placed between two fixed frames 71. Then, the two electric telescopic rods 7 are used to move the fixed frames 71 towards the center, thereby firmly fixing the base of the blade 3 onto the upright plate 2. Then, the switches of the motor 64 on the support plate 63 and the flow control valve 51 are activated in sequence. The motor 64 drives the lead screw 6 to rotate, and the lead screw 6 drives the connecting plate 43 on the transmission block 62 to reciprocate in the horizontal direction, thereby conveniently moving the cleaning fluid nozzle 45 and the cleaning brush head 47 on the surface of the blade 3. At the same time, the cleaning fluid in the storage container 5 is discharged through the flow control valve 51. The cleaning fluid pipe 52 flows into the transfer box 44, and the cleaning fluid is sprayed onto the surface of the blade 3 through the cleaning fluid nozzle 45 on the transfer box 44, thereby enabling convenient and efficient cleaning of the surface of the blade 3. At the same time, the cleaning fluid is recycled using the recovery box 53. During recycling, the used cleaning fluid is filtered by the filter screen 56 inside the recovery box 53, which can effectively remove impurities from the used cleaning fluid and ensure that the cleaning fluid is in a clean state when used. Then, the cleaning fluid recovered in the recovery box 53 is transported to the storage container 5 through the circulation pipe 55 by the circulation pump 54, thereby realizing the recycling of the cleaning fluid and reducing resource waste.

[0028] 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.
