[0023] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0024] The utility model discloses an electric drive axle hoisting auxiliary tool, which includes a connecting piece, one end of which is provided with a main fixing pin 9, and the other end of the connecting piece is provided with a hoisting hole 1 for hoisting. In order to increase the stability of the connection, a connecting block 5 is also installed on one side of the connecting piece, and the connecting block 5 is provided with a secondary fixing pin 6 at the end away from the connecting piece. When the device is in use, the main fixing pin 9 and the secondary fixing pin 6 are respectively inserted into two corresponding riding bolt holes of the leaf spring seat, which can effectively connect the electric drive axle with the hoisting equipment, and can prevent the single electric drive axle from rotating downward during hoisting, thereby realizing safe and convenient hoisting of the electric drive axle, while improving production efficiency.

[0025] In this embodiment, if Figure 1 The connecting block 5 is rotatably mounted on one side of the connecting piece, so that when the secondary fixing pin 6 is installed and inserted into the saddle bolt hole, the position of the secondary fixing pin 6 can be adjusted by rotating the connecting block 5 to ensure that it is accurately aligned with the position of the saddle bolt hole, thereby improving the flexibility of operation and having strong applicability.

[0026] Specifically in this embodiment, a rear mounting hole 3 is provided on one side of the connecting member, and correspondingly, a rotating shaft 4 is installed at one end of the connecting member, and the rotating shaft 4 is installed in the rear mounting hole 3, so that the connecting block 5 can rotate around the connecting member, thereby providing greater operational flexibility and assembly efficiency.

[0027] More specifically, the lower end of the rotating shaft 4 has a flange, and the flange radially protrudes from the outer circumference of the rotating shaft 4. When the rotating shaft 4 is located in the rear mounting hole 3, the flange is adjacent to the lower end surface of the rear mounting hole 3, so that the connecting block 5 has only one degree of freedom, that is, it can only rotate relative to the rear mounting hole 3. When the auxiliary fixing pin 6 at the other end of the connecting block 5 is located in the saddle bolt hole, looseness between the connecting block 5 and the connecting member can be avoided, making the connection more stable.

[0028] like Figure 1 As shown, the connecting piece includes a connecting rod 2 and a connecting plate 7, and the connecting rod 2 and the connecting plate 7 are fixed as a whole by welding, wherein the cross section of the connecting plate 7 is rectangular, so that when the tool is used, the lower bottom surface of the connecting piece fits with the upper surface of the leaf spring seat. In addition, the end surface of one end of the lifting hole 1 is in the same plane as a plate surface of the connecting plate 7. The end surface of the hole used for lifting and a plane of the connecting plate 7 are coplanar, so that the components can remain stable and coordinated during assembly and use, and the firmness and reliability of the overall structure are improved.

[0029] In this embodiment, a front mounting hole 8 is provided at one end of the connecting plate 7 away from the lifting hole 1, and the upper end of the main fixing pin 9 is installed in the front mounting hole 8, so that the main fixing pin 9 can rotate relative to the connecting plate 7, thereby making the entire structure more flexible and convenient during installation and use. In other embodiments, the upper end of the main fixing pin 9 is welded and fixed to the end of the connecting plate 7 away from the lifting hole 1, and this welding and fixing method can provide a more stable connection performance. It should be understood that no matter what fixing method is used, the axis of the main fixing pin 9 should be perpendicular to the length direction of the connecting plate 7. This can ensure the accurate positioning of the main fixing pin 9 and the stability and reliability of the overall structure during use.

[0030] On the other hand, a fastening nut 10 is also installed at the lower end of the main fixing pin 9. When the main fixing pin 9 is inserted into the saddle bolt hole of the leaf spring seat, its bottom design allows it to extend from the bottom of the hole, so that the main fixing pin 9 can be tightened and fixed by rotating the fastening nut 10. Thus, by locking the fastening nut 10, the stability of the main fixing pin 9 after installation can be ensured. As shown in the figure, a washer is also arranged above the fastening nut 10. The cooperation between the fastening nut 10 and the washer can further enhance the reliability of the entire structure.
