Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but these descriptions do not constitute a limitation on the present invention.

[0020] like Figure 1-4 As shown, the present invention includes a tooling base 8 and a rotating disk 5, the rotating disk 5 being rotatably connected to the tooling base 8, and also includes multiple aviation connector positioning tooling 1 disposed on the rotating disk 5. The multiple aviation connector positioning tooling 1 are fixed in equal sections along the circumference of the rotating disk 5. The multiple aviation connector positioning tooling 1 are respectively provided with positioning cavities 3 with different positioning structures. The positioning cavities 3 are used to position aviation connectors of different models and specifications. The positioning cavity 3 is arranged with an installation position detection switch pin 13. The installation position detection switch pin 13 is used to contact the aviation connector to detect whether the aviation connector is installed in place. The installation position detection switch pin 13 is electrically connected to an indicator light 4 and a power supply 14.

[0021] A positioning pin hole 6 is provided between adjacent aviation insertion positioning fixtures 1, and a spring ball pin 9 is provided on the fixture base 8 to cooperate with the positioning pin hole 6.

[0022] The positioning fixture 1 is fixed to the rotating disk 5 by bolts 2 on all four sides.

[0023] The center of the rotating disk 5 is limited by one end of the spline shaft 7, and the other end of the spline shaft 7 is rotatably connected to the tooling base 8 through the bearing 10.

[0024] The bearing 10 is located in the middle of the tooling base 8.

[0025] The power supply 14 is located on the side wall of the tooling base 8.

[0026] The upper surface of the aviation insertion positioning fixture 1 is marked with wire color and aviation insertion hole position markings 11.

[0027] The upper surface of the aviation insertion positioning fixture 1 is marked with aviation insertion fixture mark 12.

[0028] Based on the appearance positioning of the aviation connector structure, this invention manufactures positioning cavities 3 of various specifications (models). The positioning cavities 3 are fixed to the rotating disk 5 with bolts 2. The rotating disk 5 is connected to the bearing 10 of the tooling base 8 through the spline shaft 7 to achieve manual rotation. A spring ball pin 9 is designed between the rotating disk 5 and the tooling base 8. When a certain model of aviation connector needs to be welded, the positioning cavity 3 is rotated to the front of the operating table and positioned at the same time. The indicator light 4 lights up, prompting the operator to place the corresponding model of aviation connector in the aviation connector positioning tooling 1 for manual welding of the wires.

[0029] like Figure 1 As shown: The working process of this invention is as follows: First, the tooling base 8 is fixed on the workbench. Various positioning cavities 3 of different specifications are designed and manufactured. Each positioning cavity 3 has an aerospace tooling mark 12. The positioning cavity 3 is fixed evenly around the rotating disk 5 using bolts 2. During welding, a suitable positioning cavity 3 can be selected by rotation. The positioning cavity 3 is rotated to face the operator and positioned. In this embodiment, as... Figure 2 As shown, the positioning structure inside the positioning cavity 3 includes an annular groove and three limiting holes in the middle of the annular groove, and the inner wall of the annular groove is provided with multiple side grooves.

[0030] like Figure 2 As shown: Place the corresponding model connector into the positioning cavity 3. The positioning cavity 3 is equipped with an installation position detection switch pin 13. If the aviation connector is installed in place, the installation position detection switch pin 13 is turned on and the indicator light 4 lights up. If the aviation connector model is incorrect, the aviation connector will not be installed in place due to the cavity error prevention design, and the tooling indicator 4 will not light up, thus playing an error prevention role.

[0031] like Figure 3 , Figure 4 As shown: Spring ball head pin 9 enables rapid positioning of the rotating plate, and the pin rebound torque is designed according to the welding conditions; bearing 10 serves to rotate and fix the spline shaft 7; battery power supply 14.

[0032] By accurately selecting and clamping the aforementioned tooling of this invention, the welding and clamping of multiple types of aviation connectors can be completed on a single tooling, avoiding damage to the connector body and improving clamping efficiency. For the shapes and structures of the clamping parts of different specifications of aviation connectors, this invention designs positioning cavities of different shapes, achieving error prevention and effectively ensuring the welding quality of the products.

[0033] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
