At present, the number of new energy vehicles in use is growing dramatically every year. In the field of electric new energy vehicles, high-voltage boxes (junction boxes) and control boxes are the core components of the electric vehicle power system. During the actual production and assembly in the high-voltage box workshop, we found that the number of bolts that need to be tightened during the installation of the auxiliary parts of the high-voltage connector is large, the installation steps are cumbersome, the tightening takes a long time, and it is easy to have untightened and leaked bolts.

The automatic tightening tool is arranged between the gear transmission group.

[0006] Preferably, the gear transmission group includes a torque input shaft, a torque input gear and a torque transmission gear. The torque input shaft is connected to the external torque tightening torque structure. The torque input shaft is provided with a torque input gear. The torque input gear is respectively meshed with the torque transmission gear on both sides. The torque transmission gear cooperates with the automatic tightening tooling transmission.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] Reference Figure 1-5 The present specific implementation adopts the following technical scheme: an unequally spaced four-axis synchronous intelligent tightening tool, comprising an upper shell 1, a gear transmission group 2, an automatic tightening tool 3, a lower shell 4 and a fastening bolt 5, wherein the upper shell 1 and the lower shell 4 are fixed by the fastening bolt 5, and the gear transmission group 2 and the automatic tightening tool 3 are arranged in the shell formed by the upper shell 1 and the lower shell 4, and the automatic tightening tool 3 cooperates with the gear transmission group 2. The automatic tightening tool 3 is arranged between the gear transmission group 2.

[0020] The gear transmission group 2 includes a torque input shaft 21, a torque input gear 22 and a torque transmission gear 23. The torque input shaft 21 is connected to the external torque tightening torque structure. The torque input gear 22 is provided on the torque input shaft 21. The two sides of the torque input gear 22 are respectively meshed with the torque transmission gear 23. The torque transmission gear 23 is matched with the four automatic tightening tools 3 for transmission.

[0021] The working principle of this specific implementation method: the torque transmission relationship during the tightening process is as follows Figure 4 As shown:

[0022] ① When tightening, a tightening torque is applied externally to the torque input shaft of the gear transmission group.

[0023] ②The gear on the torque input shaft drives the transmission gear to transmit the tightening torque to the automatic tightening tooling.

[0024] ③ The automatic tightening tool works according to the pre-set tightening torque to tighten the bolts.

[0025] The four automatic tightening tools perform tightening operations synchronously. When one of them reaches the tightening condition, the automatic tightening tool will stop tightening, and the other three will continue tightening, and so on until all four bolts are tightened.

[0026] This specific implementation uses an automatic tightening tool and meshing gears to realize the intelligent tightening judgment of four bolts. Each tightening unit operates independently, and the maximum torque of each tightening unit can be independently customized to meet different torque application scenarios. It is an intelligent tightening tool with simple parts, low cost, flexible application, and easy operation. In the actual application of production and assembly, it can also effectively reduce the installation operation process, optimize the installation operation steps, and effectively improve production efficiency.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
