When the moving motor 25 is started to drive the moving lead screw 24 to rotate, the moving lead screw 24 rotates to drive the positioning plate 21 to move, and thus the moving work of the positioning plate 21 can be completed.

[0044] Referring to Figure 1 and Figure 2, a limiting mechanism 23 is arranged on the positioning plate 21 and is used to limit the position of the joint and keep the joint in a horizontal state. The limiting mechanism 23 includes limiting blocks 26, a flat plate 27 and a sliding assembly 28. A plurality of limiting blocks 26 are provided. The plurality of limiting blocks 26 are slidably mounted on the inner side wall of the positioning groove 12 of the positioning plate 21 along the direction close to or away from the center of the positioning groove 12. The flat plate 27 is fixedly mounted on one side wall of the limiting block 26 close to the center of the positioning groove 12. A rubber soft pad is fixedly mounted on the surface of the flat plate 27.

[0045] Referring to Figure 1 and Figure 2 , the sliding assembly 28 is arranged on the positioning plate 21 and is used to drive the plurality of limiting blocks 26 to move synchronously. The sliding assembly 28 includes a sliding rod 31, a turntable 32 and a rotating motor 33. The sliding rod 31 is slidably mounted on one side wall of the positioning plate 21 close to the body 11 of the swaging machine along the direction close to or away from the center of the positioning groove 12 and is located in the positioning groove 12. The turntable 32 is rotatably mounted on one side wall of the positioning plate 21 close to the body 11 of the swaging machine and is located in the positioning groove 12. A plurality of inclined sliding grooves 13 are circumferentially formed on the surface of the turntable 32 along the center of the turntable 32.

[0050] The position of the positioning plate 21 is adjusted by using the moving motor 25 so that the position of the connector after being inserted into the positioning groove 12 is suitable for the swaging operation of the body 11 of the swaging machine. After the connector is inserted into the positioning groove 12 of the positioning plate 21, the rotating motor 33 starts to drive the limiting block 26 to limit the position of the connector and keep the connector in a horizontal state, thus facilitating the swaging operation of the connector. After the connector is swaged, the connector can be taken out from the positioning groove 12. The steps are simple, the positioning work is convenient and fast, and the operator only needs to insert the connector into the positioning groove 12 of the positioning plate 21 to ensure that the swaging position of each swaged connector is the same, improving the accuracy of connector swaging and ensuring the quality of each connector finished product.
