[0002] Thin-walled aerospace components are indispensable key parts in the aerospace manufacturing industry. They are widely used in core parts of aircraft such as fuselage, wings, and tail, and their processing quality is directly related to the overall performance and flight safety of the aircraft.

[0003] When machining aerospace parts, debris is generated. Although some existing devices have debris cleaning functions, the blowing angle and range of the debris cleaning device are fixed, making it difficult to fully cover the area where debris is generated during drilling, resulting in poor blowing effect and incomplete debris cleaning.

[0004] Moreover, the table surface of traditional tooling is mostly flat, making it difficult to quickly and thoroughly collect the debris generated by blowing. Some debris will remain in the gaps of the table surface or the corners of the parts, requiring frequent manual cleaning. Therefore, a drilling tooling for thin-walled aerospace parts with blowing function is proposed to solve the above problems. Utility Model Content

[0024] 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.

[0025] Please see Figures 1-6 This embodiment of a drilling fixture for thin-walled aerospace components with a purging function includes a table 1, a vertical plate 2 and a horizontal plate 3. A drilling assembly 4 is provided at the bottom of the horizontal plate 3, and a purging mechanism 5 is provided on the front side of the vertical plate 2.

[0026] The purging mechanism 5 includes a housing 51. A motor 52 is provided on the right side of the housing 51. A lead screw 53 is fixedly installed at the output shaft of the motor 52 and is rotatably connected to the left inner wall of the housing 51. A threaded sleeve 54 is threaded to the outer surface of the lead screw 53. A swing arm 55 is hinged to the front side of the threaded sleeve 54.

[0027] The purging mechanism 5 also includes a sliding cavity 56. The sliding cavity 56 is provided on the vertical plate 2. An electric push rod 58 is provided on the rear side of the vertical plate 2. A slider 57 that is slidably connected to the sliding cavity 56 is fixedly installed at the bottom of the electric push rod 58. A connecting rod 59 is fixedly installed between the front side of the slider 57 and the rear side of the housing 51.

[0028] The sliding cavity 56 on the upright plate 2 provides a sliding track for the slider 57. When the electric push rod 58 extends or retracts, it drives the slider 57 to move up and down along the sliding cavity 56. The connecting rod 59 synchronously drives the housing 51 to rise and fall. This design enables flexible adjustment of the overall height of the blowing mechanism 5, which can be adapted to the drilling position of thin-walled parts of different thicknesses, and solves the problem of fixed height of traditional blowing components.

[0029] The motor 52 on the right side of the housing 51 drives the lead screw 53 to rotate, causing the threaded sleeve 54 to move left and right along the lead screw 53. The sleeve 54 swings through the hinged rocker arm 55. The rocker arm 55 slides with the rod body inside the through hole of the housing 51 through the sliding mouth to ensure the stability of the swing process. This structure allows the air nozzle 511 at the end of the rocker arm 55 to achieve multi-angle blowing, covering different directions of the drilling area and avoiding the blind spots of traditional fixed-angle blowing.

[0030] The air pump 512 at the top of the housing 51 generates high-pressure airflow, which is delivered to the air nozzle 511 through the bellows 513. The flexible characteristics of the bellows 513 allow it to freely extend and retract with the swing arm 55, ensuring stable airflow delivery.

[0031] The front, left, and right slopes 12 of the top of the tabletop 1 are designed to be inclined, and together with the edge baffles 11, they form a barrier to prevent debris from splashing. The guide port 13 between the baffles 11 and the slopes 12 guides the blown debris to the edge of the tabletop 1, which solves the problem of debris accumulation in traditional flat workbenches. The slide 14 at the bottom of the tabletop 1 is connected to the guide port 13. After the debris falls into the slide 14 through the guide port 13, it finally enters the plugged collection drawer 15. The collection drawer 15 can be directly pulled out from the slide 14 for cleaning, realizing the rapid centralized processing of debris and reducing the frequency of manual cleaning.

[0032] When using this drilling fixture for thin-walled aerospace parts with a blowing function, the thin-walled aerospace part is first placed on the table 1 and fixed with a clamp. Then, according to the thickness of the thin-walled part and the drilling position, the electric push rod 58 on the rear side of the vertical plate 2 is activated. The extension and retraction of the electric push rod 58 will drive the slider 57 fixed thereto to slide in the sliding cavity 56 on the vertical plate 2. The slider 57 drives the housing 51 to move up and down through the connecting rod 59, thereby adjusting the overall height of the blowing mechanism 5. After that, the drilling assembly 4 at the bottom of the horizontal plate 3 is activated to drill the thin-walled aerospace part. During the drilling process, the air pump 512 at the top of the housing 51 is turned on. The airflow generated by the air pump 512 is delivered to the air nozzle 511 through the bellows 513. The air nozzle 511 blows air into the area where the drilling produces debris. At the same time, the motor 52 on the right side of the housing 51 is activated. The output shaft of the machine 52 drives the lead screw 53 to rotate inside the housing 51. The rotation of the lead screw 53 causes the threaded sleeve 54 connected to the outer surface to move left and right. The threaded sleeve 54 drives the swing rod 55, which is hinged at the front, to move. Since the swing rod 55 is slidably connected to the rod body on the inner wall of the through-hole at the front of the housing 51 through the internal sliding port, the swing rod 55 will swing, thereby driving the air nozzle 511 to change the blowing angle, so as to blow the drilling area in different directions. The debris generated by drilling will be blown towards the slope 12 at the top of the table 1 by the air nozzle 511. The baffle 11 at the top edge of the table 1 can prevent the debris from splashing out of the tooling. The debris slides along the slope 12 to the guide port 13 between the baffle 11 and the slope 12, and enters the slide table 14 at the bottom of the table 1 through the guide port 13, and finally falls into the collection drawer 15 inserted in the slide table 14.

[0033] In summary, this drilling fixture for thin-walled aerospace parts with a blowing function, through the setting of a blowing mechanism 5, wherein the motor 52 drives the lead screw 53 to rotate, causing the lead sleeve 54 to move left and right, so that the hinged swing rod 55 can swing through the sliding engagement between the sliding mouth and the rod body in the through-hole of the housing 51. In conjunction with the electric push rod 58, the slider 57 slides in the sliding cavity 56. The height of the housing 51 can be adjusted by the connecting rod 59, so that the blowing nozzle 511 can flexibly change the blowing angle and height, fully covering the drilling area, effectively solving the problems of poor blowing effect and incomplete debris removal caused by the fixed blowing angle and range of existing devices.

[0034] Furthermore, by setting a slope 12, baffle 11 and guide port 13 at the top of the tabletop 1, and cooperating with the slide 14 and collection drawer 15 at the bottom, the debris after blowing can enter the slide 14 along the slope 12 through the guide port 13, and finally be collected in the collection drawer 15. This solves the problem that debris is difficult to collect quickly and thoroughly on traditional flat workbenches and requires frequent manual cleaning, reduces the amount of manual cleaning work, and improves work efficiency.
