[0023] Embodiment

[0024] Please refer to Figures 1-4 , an installation and spinning device for an aeroengine filter screen, comprising a machine frame 1, a drive motor 2, a grip holder 3, a drive shaft 5, a movable frame 6, a bidirectional screw 7, a screwing disc 8, a movable block 9, a threaded sleeve 10, a top frame 11 and a contact pad 12. The top end inside the machine frame 1 is connected to the top end of the drive motor 2. The output end of the drive motor 2 is connected to the middle of the bottom end of the movable frame 6 through the drive shaft 5. The bottom end inside the movable frame 6 is slidably connected to the bottom ends of two movable blocks 9. A bidirectional screw 7 is rotatably connected horizontally inside the movable frame 6. The right end of the bidirectional screw 7 is connected to the middle of the inner end of the screwing disc 8. Threaded sleeves 10 are arranged inside the movable blocks 9. The inner wall of the threaded sleeve 10 is screwed to the outer wall of the bidirectional screw 7. The top end of each group of movable blocks 9 is respectively connected to the bottom end of a top frame 11. The outer side of the upper part of the top frame 11 is connected to the inner side of the contact pad 12. The middle parts of the left and right ends of the machine frame 1 are respectively connected to the inner ends of a group of grip holders 3. During use, make the two movable blocks 9 located in the middle position inside the movable frame 6, and the distance between the two top frames 11 is relatively close. Then, put the filter screen to be installed on the outer sides of the two top frames 11. Then, turn the screwing disc 8 to make the bidirectional screw 7 rotate. The bidirectional screw 7 is screwed with the two threaded sleeves 10 to make the two threaded sleeves 10 respectively drive the corresponding movable blocks 9 to slide outward inside the movable frame 6, so as to drive the corresponding top frames 11 to move outward, making the contact pad 12 abut against the inner side of the filter screen. After the adjustment is completed, the bidirectional screw 7 and the threaded sleeve 10 are locked by threads. Then, hold the two grip holders 3 respectively, move the device with the filter screen to the installation position, and through the operation of the drive motor 2, the drive shaft 5 rotates to drive the filter screen to rotate and thus be spin-fixed.

[0025] It further includes a clamping wheel 13, a connecting piece 14, a spring 15 and a clamping plate 16. The left side of the bidirectional screw 7 is connected to the middle part of the inner side of the clamping wheel 13. The lower end of the left side of the movable frame 6 is connected to the inner end of the connecting piece 14. The top end of the connecting piece 14 is connected to the bottom end of the clamping plate 16 through the spring 15. Under the connection of the connecting piece 14, through the elastic action of the spring 15, the clamping plate 16 can be pushed upwards to act on the outer side of the clamping wheel 13 to clamp it, thus preventing it from rotating and improving stability.

[0026] It further includes a sliding sleeve 17, a sliding rod 18 and a pulling piece 19. The inner side of the middle part of the connecting piece 14 is connected to the outer side of the sliding sleeve 17. The inner wall of the sliding sleeve 17 is slidably connected to the outer wall of the sliding rod 18. The top end of the sliding rod 18 is connected to the middle part of the bottom end of the clamping plate 16. The bottom end of the sliding rod 18 is connected to the middle part of the top end of the pulling piece 19. By pulling the pulling piece 19, the sliding rod 18 can slide down in the sliding sleeve 17, thereby driving the clamping plate 16 to release the clamping on the clamping wheel 13, facilitating the rotation of the bidirectional screw 7.

[0027] It further includes a storage battery 20 and a charging socket 21. The bottom end of the machine frame 1 is connected to the top end of the storage battery 20. The input end of the storage battery 20 is provided with the charging socket 21. The output end of the storage battery 20 is connected to the input end of the driving motor 2. The storage battery 20 can be charged through the charging socket 21. The storage battery 20 stores electricity and supplies energy for the operation of the driving motor 2, improving practicability.

The dust plug 23 is connected and prevented from being lost through the connecting piece two 22, and when not charging, the dust plug 23 can be inserted into the charging socket 21 for protection, improving reliability.

[0029] It further includes a grip sleeve 24. Each group of grip frames 3 is respectively sleeved with a group of grip sleeves 24. The grip frames 3 are held through the contact with the grip sleeves 24, increasing the static friction force, preventing slipping and improving stability.

[0030] In summary, when an aviation engine filter installation spinning device is in use, during use, the two movable blocks 9 are positioned in the middle of the movable frame 6, and the two top frames 11 are relatively close. Then, the filter to be installed is sleeved outside the two top frames 11. By pulling the pull tab 19, the sliding rod 18 can slide down in the sliding sleeve 17, thereby driving the clamping plate 16 to release the clamping wheel 13. Then, turn the screwing disc 8 to rotate the bidirectional screw rod 7. The bidirectional screw rod 7 is screwed and matched with the two threaded sleeves 10, so that the two threaded sleeves 10 respectively drive the corresponding movable blocks 9 to slide outward on the inner side of the movable frame 6, thereby driving the corresponding top frames 11 to move outward, making the contact pad 12 abut against the inner side of the filter. After the adjustment is completed, under the connection of the connecting piece 14, under the elastic action of the spring 15, the clamping plate 16 can be pushed upward to act on the outer side of the clamping wheel 13 to clamp it tightly, thereby preventing it from rotating. After the bidirectional screw rod 7 and the threaded sleeve 10 are thread-locked, then respectively hold the two handle frames 3 through the handle sleeves 24 in contact, and drive the device with the filter to the installation position. Power is supplied from the storage battery 20 to the drive motor 2 to operate, and the main shaft 5 rotates to drive the filter to rotate and be spin-fixed. In addition, the storage battery 20 can be charged through the charging socket 21, and the dust-proof plug 23 is connected to the connecting piece two 22 to prevent loss, and the dust-proof plug 23 can be inserted into the charging socket 21 for protection when not charging.
