Description

TECHNICAL FIELD

[0002] In the field of electronic and electrical products, plug power cords are indispensable accessories, and their quality is directly related to the safety and performance of the products. The traditional plug power cord production method adopts an integrated connection process of plug and power cord, that is, the plug and power cord are directly fixed and connected into a whole during the production process. Although this production method is relatively simple, it has many drawbacks: On the one hand, the integrated connection makes the connection mode between the plug and the power cord relatively fixed, and it is difficult to adjust flexibly according to actual needs. For example, when the power cord is damaged or needs to be replaced with a different specification plug, the entire plug power cord often needs to be replaced, increasing the use cost and resource waste. On the other hand, the traditional production method lacks effective testing of the performance of the power cord. In actual use, the power cord needs to withstand frequent bending and other operations, and if its bending fatigue strength is insufficient, it can easily lead to line breakage, poor contact and other problems, thereby causing safety hazards. However, the traditional production method cannot test the bending fatigue strength of the power cord in real time during the production process, cannot timely discover and solve potential quality problems, and cannot guarantee product quality and user safety.

The threaded assembly includes an internal threaded ring 13 rotatably sleeved on the protective hose 11. An external threaded ring 12 is fixedly installed on one side of the plug housing 5 by welding. The external threaded ring 12 is threadedly connected to the internal threaded ring 13, thereby realizing the fixed connection between the power cord 9 and the plug housing 5. A transmission knob 14 is also fixedly sleeved on the internal threaded ring 13. A plurality of arc-shaped grooves are arranged at equal intervals on the outer curved surface of the transmission knob 14.

[0016] As shown in Figure 1 , Figure 2 , and Figure 4As shown, the production device further comprises a driving mechanism penetrating through and connected with the first support plate 2, which is used to drive the threaded assembly to move, thereby connecting the power cord 9 with the plug mechanism. The driving mechanism comprises a driving motor 16 fixedly installed on the other side of the first support plate 2 by bolts, and the output shaft of the driving motor 16 penetrates through the first support plate 2 and is fixedly installed with a transmission shaft 17 through a shaft coupling. A transmission wheel 18 is rotatably sleeved on the transmission shaft 17, and a plurality of arc protrusions are equidistantly arranged on the transmission wheel 18 and are in transmission cooperation with a plurality of arc-shaped grooves.
