Description

Technical Field

[0001] The utility model relates to a positioning tool, in particular to a positioning tool used for installing an air inlet and a transition section of a target drone. Background Art

[0002] A target drone is a military aircraft used as a target for shooting training. When assembling the target drone, the engine is generally installed first, and then the air inlet and the adapter section are placed into the body of the target drone. The initial overlap of the air inlet, the adapter section and the air intake of the engine is observed, the approximate cutting distance is estimated, and the air inlet is positioned and cut. After the cutting is completed, the air inlet, the adapter section and the air intake of the engine are completely connected.

[0003] However, due to the internal space limitations of the target drone, not only is it easy for the air intake to not be cut into place in one go, requiring multiple cuts, resulting in low cutting efficiency, but it is also easy to cause large cutting errors in the air intake, and even cause the air intake to be damaged due to excessive cutting. Utility Model Content

[0004] Purpose of the utility model: The purpose of the utility model is to provide a positioning tool for installing the air intake duct and the transition section of the target drone, which not only facilitates the one-time cutting of the air intake duct into place, but also reduces the cutting error of the air intake duct.

[0024] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1This embodiment provides a positioning tool for installing the air inlet duct and transition section of a target drone, including: an air inlet dummy 3, one end of the air inlet dummy 3 is used to be sleeved on the outside of one end of the transition section 2; a dial 4 connected to the other end of the air inlet dummy 3; a plurality of fasteners 5 that are all radially threadedly connected to the air inlet dummy 3, and the plurality of fasteners 5 are all used to interfere with the outside of one end of the transition section 2; a plurality of fixing beams 6, one end of the plurality of fixing beams 6 are connected to the other end of the air inlet dummy 3, and the other end of the plurality of fixing beams 6 are used to be detachably connected to the other end of the transition section 2 and the air inlet 1.

[0027] Specifically, during operation, first, one end of the transition section 2 is sleeved into the air inlet simulation component 3, and by adjusting the radial positions of several fasteners 5 and according to the dial 4, one end of the transition section 2 is made concentric with the air inlet simulation component 3; then, the other end of the transition section 2 is connected to the other end of several fixed beams 6; then, the air inlet 1 is connected to the other end of several fixed beams 6, so that the air inlet 1 and the other end of the transition section 2 are concentric; further, outside the body of the relevant target aircraft, a cutting line is drawn on the air inlet 1, and then the air inlet 1 is cut according to the cutting line, which not only makes it convenient to cut the air inlet 1 into place at one time, thereby improving the cutting efficiency, but also makes the cutting error of the air inlet 1 small, preventing the air inlet 1 from being damaged due to excessive cutting; finally, the air inlet 1, the transition section 2 and the air inlet of the engine are completely connected inside the body of the relevant target aircraft.

[0028] Among them, the air inlet simulation part 3 is used to simulate the air inlet of the relevant engine; the dial 4 is used to locate the radial position of one end of the transition section 2, so that one end of the transition section 2 and the air inlet simulation part 3 are concentric; the fastener 5 is used to lock one end of the transition section 2, and the fastener 5 can be a pan head screw, a cylindrical head screw, etc. The number of fasteners 5 is not limited, and can be three, four, etc., preferably three; the fixed beam 6 is used to fix the air inlet simulation part 3, the transition section 2 and the air inlet duct 1, so as to simulate the installation position of the air inlet, the transition section 2 and the air inlet duct 1 of the relevant engine in the body of the relevant target aircraft. The number of fixed beams 6 is not limited, and can be three, four, etc., preferably three.

[0029] Further, such as Figure 2The fixed beam 6 includes: a beam body 63; a first fixing portion 61 and a second fixing portion 62 respectively connected to the two ends of the beam body 63, the first fixing portion 61 being connected to the other end of the air inlet simulated component 3, and the second fixing portion 62 being used for detachable connection with the other end of the transition section 2 and the air inlet duct 1. Specifically, the beam body 63 is used to connect the first fixing portion 61 and the second fixing portion 62; the first fixing portion 61 facilitates increasing the connection area between the fixed beam 6 and the other end of the air inlet simulated component 3; the second fixing portion 62 facilitates increasing the detachable connection area between the fixed beam 6 and the other end of the transition section 2 and the air inlet duct 1; the connection method between the beam body 63 and the first fixing portion 61 and the second fixing portion 62 is not limited, and can be an integrally formed bending connection, welding, etc.

[0030] Further, such as Figure 2 The first fixing portion 61 and the second fixing portion 62 are both integrally formed and bent to connect with the beam body 63. Specifically, the integrally formed and bent connection facilitates good integrity of the connection between the beam body 63 and the first fixing portion 61 and the second fixing portion 62.

[0031] Further, such as Figure 2 The scale plate 4 includes a first scale 41 and a second scale 42, both connected to the other end of the air inlet simulated component 3. The middle portion of the first scale 41 and the middle portion of the second scale 42 are integrally connected. Specifically, the first scale 41 and the second scale 42 facilitate bidirectional positioning of one end of the adapter section 2, achieving effective positioning. The integral connection ensures the integrity of the first scale 41 and the second scale 42.

[0032] Further, such as Figure 2 The first scale 41 and the second scale 42 are perpendicular to each other. Specifically, being perpendicular to each other facilitates good distribution uniformity of the first scale 41 and the second scale 42.

[0033] Further, such as Figure 2 The plurality of fasteners 5 are evenly distributed along the circumference of the air inlet member 3. Specifically, the circumferential uniform distribution facilitates good uniformity of the force outside one end of the transition section 2.

[0034] Further, such as Figure 2 , the number of fasteners 5 is three.

[0035] Further, such as Figure 2 , the number of fixed beams 6 is three.

[0036] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
