[0039] The core of this invention is to provide a pitot tube calibration drilling device suitable for unmanned aerial vehicles (UAVs).

[0040] Please refer to Figures 1-7 .

[0041] The pitot tube calibration drilling device for UAVs provided by this utility model includes a base 1, a sleeve 2, a limiting component 6, a measuring plate 4, and a drilling component 5. The sleeve 2 is sleeved on the first side of the base 1, and an annular mounting cavity 3 is formed between the sleeve 2 and the base 1. The mounting cavity 3 is used to place the pitot tube. The limiting component 6 is set on the sleeve 2 and is used to fix the pitot tube within the mounting cavity 3. The measuring plate 4 is fixedly set on the second side of the base 1 and is used to cooperate with a laser measuring instrument for leveling. The drilling component 5 is set on the base 1 and the sleeve 2 and is used to cooperate with drilling equipment to drill holes in the pitot tube.

[0042] Specifically, the sleeve 2 is fitted onto the first side of the base 1, and an annular mounting cavity 3 is formed between the outer wall of the base 1 and the inner wall of the sleeve 2. The mounting cavity 3 serves as a slot for placing the airspeed tube between the base 1 and the sleeve 2, facilitating subsequent calibration and drilling operations. During the calibration process, to facilitate calibration by the laser measuring instrument, a measuring plate 4 is installed on the second side of the base 1. The connection between the measuring plate 4 and the base 1 is at the middle of the measuring plate 4. The laser measuring instrument measures a point at the middle and two points at both ends of the measuring plate 4, which are located on the same plane, to complete the calibration and leveling of the entire fixture, thereby completing the calibration and leveling of the airspeed tube (see attached diagram for specific measurement positions). Figure 7(As shown). During the drilling process, since the calibration work has been completed beforehand, the pitot tube is fixed inside the mounting cavity 3 by means of the limiting component 6. Then, through the cooperation of the drilling component 5 and the drilling equipment, a hole is drilled in the pitot tube at the designated position, realizing the simultaneous completion of calibration and drilling. Moreover, this solution only requires two people to carry out the construction process: one person installs and adjusts the tooling and drills the hole, and the other person is responsible for operating the laser measuring instrument, which greatly reduces labor costs.

[0043] The aforementioned pitot tube calibration drilling device for UAVs inserts the pitot tube into the mounting cavity 3 between the base 1 and the sleeve 2. A measuring plate 4, in conjunction with a laser measuring instrument, performs leveling. After leveling, a limiting component 6 fixes the pitot tube within the mounting cavity 3. A drilling component then drills a hole in the pitot tube. This achieves simultaneous drilling and leveling, resulting in a simple process, high overall device accuracy, and small error.

[0044] The pitot tube calibration drilling device for UAVs provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0045] In one specific implementation, reference is made to... Figure 1 and Figure 2 The drilling assembly 5 includes a plurality of drill sleeves 51 disposed on the sleeve 2. The sleeve 2 has mounting holes 52 corresponding to the drill sleeves 51. The drill sleeves 51 are fixedly disposed in the corresponding mounting holes 52. The base 1 has chip removal holes 53 corresponding to the drill sleeves 51.

[0046] Specifically, mounting holes 52 are formed on the sleeve 2, and multiple holes are formed along the outer surface of the sleeve 2 according to the drilling position of the airspeed tube. Each mounting hole 52 is equipped with a drill sleeve 51 that cooperates with the drilling equipment. The airspeed tube is drilled by drilling equipment through the drill sleeve 51. The drilling equipment is a conventional drilling equipment in the prior art. At the same time, in order to avoid the accumulation of iron filings generated during drilling in the mounting cavity 3, chip removal holes 53 corresponding to the drill sleeve 51 are formed on the base 1. The iron filings generated during drilling enter the base 1 through the chip removal holes 53, avoiding accumulation in the mounting cavity 3 and affecting subsequent drilling.

[0047] Furthermore, each drill sleeve 51 is provided with a set screw between it and the corresponding mounting hole 52, so that the drill sleeve 51 is fixedly installed in the mounting hole 52.

[0048] Specifically, the drill sleeve 51 located in the mounting hole 52 is further fixed by the set screw to ensure the stability of the drill sleeve 51 during the drilling process.

[0049] Based on any of the above embodiments, refer to Figure 1 and Figure 2The limiting component 6 includes multiple limiting bolts 61 disposed on the sleeve 2. The sleeve 2 has multiple limiting holes 62 that cooperate with the limiting bolts 61. The limiting bolts 61 are threadedly connected to the limiting holes 62, and the end of the limiting bolts 61 near the mounting cavity 3 abuts against the outer surface of the airspeed tube.

[0050] Specifically, the limiting holes 62 are opened on the outer surface of the sleeve 2, and each pair of limiting holes 62 are arranged opposite each other. Each limiting hole 62 is threaded with a limiting bolt 61. The limiting bolt 61 can be raised or lowered within the limiting hole 62. After the airspeed tube is calibrated, the position of the limiting bolt 61 within the limiting hole 62 is adjusted so that the end of the limiting bolt 61 closest to the airspeed tube abuts against the outer wall of the airspeed tube. Multiple limiting bolts 61 cooperate with each other to clamp the airspeed tube and ensure the stability of the airspeed tube before drilling.

[0051] Based on any of the above embodiments, the sleeve 2 and the base 1 are respectively provided with a first fixing hole and a second fixing hole that cooperate with each other. Fixing pins are inserted into the first fixing hole and the second fixing hole to fix the base 1 and the sleeve 2 relative to each other.

[0052] Specifically, a first fixing hole is formed on the sleeve 2, and a second fixing hole is formed on the base 1 at the corresponding position. The sleeve 2 is fitted onto the base 1, and the first fixing hole and the second fixing hole are aligned, so that the fixing pin passes through the first fixing hole and the second fixing hole, thereby fixing the base 1 and the sleeve 2. Other fixing methods can also be used, such as fixing with screws, to still achieve relative fixing between the sleeve 2 and the base 1.

[0053] Based on any of the above embodiments, refer to Figures 1-4 The base 1 includes an end and a body that are connected to each other. The cross-sectional dimension of the end is larger than that of the body. The sleeve 2 is fitted onto the body of the base 1. The measuring plate 4 is fixedly installed on the side wall of the end of the base 1.

[0054] Specifically, the base 1 consists of a body and ends with different inner diameters, and its longitudinal section is T-shaped. The sleeve 2 is fitted onto the body of the base 1, with one side of the sleeve 2 abutting against one side of the end of the base 1, ensuring a tight fit between the base 1 and the sleeve 2. The measuring plate 4 is fixedly installed on the side wall of the end of the base 1, facilitating calibration and leveling operations in conjunction with a laser measuring instrument.

[0055] Based on any of the above embodiments, the surfaces of the base 1 and the sleeve 2, except for the openings, are subjected to anodized sandblasting treatment.

[0056] Specifically, both the surface of the base 1 and the surface of the sleeve 2 (excluding the openings on both surfaces) undergo surface anodizing and sandblasting treatment. This removes dirt, grease, oxide layers, fine scratches, and other uneven defects from the tooling surface, making the surface cleaner and smoother. It also helps to form a more uniform and dense oxide film during the anodizing process, improving the overall surface quality.

[0057] Based on any of the above embodiments, refer to Figure 1 The pitot tube calibration drilling device for UAVs provided by this utility model also includes an observation hole 7 opened on the sleeve 2. The observation hole 7 is used to check whether the pitot tube and the inner wall of the mounting cavity 3 are tightly fitted.

[0058] Specifically, the observation hole 7 is opened on the outer surface of the sleeve 2, and its spatial position is located at the innermost side of the mounting cavity 3 where the airspeed tube is located. It is mainly used to check the gap between the airspeed tube and the bottom of the mounting cavity 3, to ensure that the airspeed tube and the mounting cavity 3 fit tightly together and to ensure that the airspeed tube is installed in place.

[0059] Based on any of the above embodiments, refer to Figure 2 The pitot tube calibration drilling device for UAVs provided by this utility model also includes a sealing component 8, which is disposed on the base 1 and is used to prevent iron filings from leaking out of the base 1.

[0060] Specifically, the sealing component 8 is located on one side of the base 1 to prevent iron filings inside the base from leaking into the airspeed tube and to prevent iron filings from entering the aircraft after drilling and becoming extraneous, thus affecting the normal operation of the UAV.

[0061] Furthermore, the sealing assembly 8 includes a sealing plate 81, which is inserted into one end of the base 1 near the opening of the mounting cavity 3.

[0062] Specifically, the sealing plate 81 is fastened to one side of the base 1 and is pressed into the base 1 using a special tool, so that the contact surfaces of the two are interference-fitted. The sealing plate 81 has a cap-like structure, which can better fasten it into the base 1. Optionally, the sealing assembly 8 can also adopt a folding cap or other structure to achieve sealing of the side of the base 1 near the pitot tube.

[0063] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0064] The above provides a detailed description of the pitot tube calibration drilling device for unmanned aerial vehicles (UAVs) provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of this utility model.
