For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] See also Figures 1 to 3 The utility model discloses a rear axle semi-axle disassembly tooling structure for an automobile, comprising a guide rod 10 and a docking assembly 20 and a limiting assembly 30 respectively arranged at both ends of the guide rod 10. A knocking block 40 is arranged on the guide rod 10, and the knocking block 40 slides back and forth along the direction of the guide rod 10. The docking assembly 20 is arranged at the first end of the guide rod 10 for connecting with the rear axle semi-axle 50. The limiting assembly 30 is arranged at the second end of the guide rod 10 for limiting the knocking block 40 to prevent the knocking block 40 from being lost after being separated from the guide rod 10, thereby causing loss of the overall function of the product.

[0025] After the docking assembly 20 is connected and fixed to the rear axle half-shaft 50, force is applied to the knocking block 40 so that the knocking block 40 moves along the direction of the guide rod 10 toward the limiting assembly 30 until the knocking block 40 applies a force to the limiting assembly 30 and transmits the force well to the guide rod 10. Finally, force is applied to the rear axle half-shaft 50 through the docking assembly 20, thereby removing the rear axle half-shaft 50 from the rear axle assembly. The structure is simple and easy to use, which effectively reduces the difficulty of disassembling the rear axle half-shaft 50.

[0026] In one embodiment, the knocking block 40 is a cylindrical structure, and the knocking block 40 is sleeved on the guide rod 10. A guide hole 41 is opened on the knocking block 40, and the guide rod 10 is set through the guide hole 41. When the knocking block 40 moves toward the limiting assembly 30 along the direction of the guide rod 10, the knocking block 40 generates a vibration impact force on the limiting assembly 30, and transmits the force to the guide rod 10 well. Finally, the rear axle half shaft 50 is exerted with force through the docking assembly 20, so that the rear axle half shaft 50 is removed from the rear axle assembly. The structure is simple and easy to use, and the difficulty of disassembling the rear axle half shaft 50 is effectively reduced.

[0027] Furthermore, the cross-sectional diameter of the guide hole 41 is larger than the cross-sectional diameter of the guide rod 10 , so that the knocking block 40 can slide back and forth along the direction of the guide rod 10 well.

[0028] In one embodiment, a plurality of groove ring portions 42 are provided on the surface of the knocking block 40, thereby facilitating the operator to hold the knocking block 40, thereby providing a force for the knocking block 40 to slide back and forth along the direction of the guide rod 10, thereby better facilitating the operator to drive the knocking block 40 to generate a vibration impact force on the limiting assembly 30.

[0029] In one embodiment, the two ends of the knocking block 40 are respectively extended to the circumferential side to provide limiting protrusions 43, and the cross-section of the limiting protrusion 43 is a circular ring structure. The two limiting protrusions 43 limit the upper and lower ends of the knocking block 40. On the one hand, the operator's hands are protected to prevent the operator from being clamped and injured when the operator holds the knocking block 40 to impact the limiting assembly 30; on the other hand, the force application area between the knocking block 40 and the limiting assembly 30 is increased to reduce the probability of damage when the knocking block 40 and the limiting assembly 30 are connected.

[0030] Alternatively, the knocking block 40 is a slider mechanism, and a guide groove is provided on the guide rod 10. The knocking block 40 is clamped in the guide groove. When the knocking block 40 moves along the direction of the guide rod 10 toward the limit assembly 30, the knocking block 40 generates a vibration impact force on the limit assembly 30, and transmits the force to the guide rod 10 well, and finally applies force to the rear axle half shaft 50 through the docking assembly 20, so as to remove the rear axle half shaft 50 from the rear axle assembly. The structure is simple and easy to use, and the difficulty of disassembling the rear axle half shaft 50 is effectively reduced.

[0031] In one embodiment, the docking assembly 20 and the limiting assembly 30 are integrally formed with the guide rod 10. This method can improve the overall rigidity of the utility model. When the knocking block 40 applies force to the limiting assembly 30, the force of the knocking block 40 on the limiting assembly 30 can be well transmitted.

[0032] Alternatively, the docking assembly 20 and the limiting assembly 30 are detachably connected to the guide rod 10. This method can improve the versatility and manufacturing efficiency of the utility model. When the docking assembly 20 and / or the limiting assembly 30 are damaged, the docking assembly 20 and the limiting assembly 30 can be directly replaced, or the docking assembly 20 can be designed into a docking structure of different sizes or shapes to facilitate connection with the rear axle half shaft 50 of different vehicle models. The docking assembly 20 of different sizes or shapes can be replaced as needed to meet the disassembly needs of the rear axle half shaft 50 of different vehicle models.

[0033] In one embodiment, the docking assembly 20 is provided with a docking block 21 and a connecting portion 22. The docking block 21 is a straight-line structure. The connecting portion 22 is arranged in the middle of the docking block 21. A connecting groove 221 is provided on the connecting portion 22. One end of the guide rod 10 is placed in the connecting groove 221. A threaded portion is provided in the connecting groove 221, so that the guide rod 10 and the connecting portion 22 are fixedly connected by threads; docking grooves 211 are respectively provided on both sides of the docking block 21, and the docking block 21 is used to connect with the rear axle half shaft 50 through a locking piece 60. The locking piece 60 passes through the docking groove 211 and is fixed on the rear axle half shaft 50, thereby realizing the connection and fixing operation between the docking block 21 and the rear axle half shaft 50; in this embodiment, the locking piece 60 is a bolt.

[0034] Furthermore, the connecting portion 22 protrudes out of the connecting portion 22 so that the thickness of the connecting portion 22 is greater than the thickness on both sides of the connecting portion 22. When the knocking block 40 hits the docking assembly 20 along the direction of the guide rod 10, the larger thickness design of the connecting portion 22 can reduce the damage of the knocking block 40 to the docking assembly 20, thereby greatly improving the service life of the docking assembly 20.

[0035] In other embodiments, the docking block 21 can also be set to a cross-shaped, Y-shaped or other structure as needed to facilitate the connection between the docking block 21 and the rear axle half shaft 50 of different models, thereby meeting the need to disassemble the rear axle half shaft 50 of different models.

[0036] In one embodiment, the limiting assembly 30 includes a limiting bolt 31 and a limiting ring piece 32. The limiting bolt 31 is fixed at the end of the guide rod 10, and the limiting ring piece 32 is placed between the limiting bolt 31 and the guide rod 10. When the knocking block 40 moves toward the limiting assembly 30 along the direction of the guide rod 10, the knocking block 40 applies force to the limiting ring piece 32 and transmits the force to the limiting bolt 31, thereby generating a vibration impact force on the limiting assembly 30 and transmitting the force to the guide rod 10 well. Finally, force is applied to the rear axle half shaft 50 through the docking assembly 20, thereby removing the rear axle half shaft 50 from the rear axle assembly. The structure is simple and easy to use, and the difficulty of disassembling the rear axle half shaft 50 is effectively reduced. In this embodiment, a limiting hole 11 is set at the end of the guide rod 10, and the limiting bolt 31 is fixed in the limiting hole 11.

[0037] In this embodiment, the diameter of the center hole on the limiting ring piece 32 is smaller than the cross-sectional diameter of the guide rod 10 , so as to facilitate fixing the limiting ring piece 32 between the limiting bolt 31 and the second end of the guide rod 10 .

[0038] Alternatively, the limiting assembly 30 is constructed with a limiting bolt 31, which is fixed to the end of the guide rod 10. When the knocking block 40 moves toward the limiting assembly 30 along the direction of the guide rod 10, the knocking block 40 applies force to the nut 311 structure of the limiting bolt 31, thereby generating a vibration impact force on the limiting assembly 30 and transmitting the force well to the guide rod 10. Finally, force is applied to the rear axle half shaft 50 through the docking assembly 20, thereby removing the rear axle half shaft 50 from the rear axle assembly. The structure is simple and easy to use, and the difficulty of disassembling the rear axle half shaft 50 is effectively reduced.

[0039] When the utility model is used specifically, the knocking block 40 is sleeved on the guide rod 10, and then the docking assembly 20 and the limiting assembly 30 are fixedly connected to the two ends of the guide rod 10 respectively, and the docking block 21 is connected to the rear axle half shaft 50 to be disassembled by using the locking piece 60; the operator holds the knocking block 40 and drives the knocking block 40 to move along the direction of the guide rod 10 toward the limiting assembly 30, and the knocking block 40 applies force to the limiting ring plate 32 and transmits the force to the limiting bolt 31, thereby achieving a vibration impact force on the limiting assembly 30, and the force is well transmitted to the guide rod 10, and finally the rear axle half shaft 50 is forced through the docking assembly 20, so that the rear axle half shaft 50 is removed from the rear axle assembly. The structure is simple and easy to use, and the difficulty of disassembling the rear axle half shaft 50 is effectively reduced.

[0040] In summary, the utility model is a tooling structure for disassembling a rear axle half-shaft of an automobile, by respectively arranging a docking assembly 20 and a limiting assembly 30 at both ends of a guide rod 10, and cooperating with a knocking block 40 on the guide rod 10, and utilizing the docking assembly 20 to connect with the rear axle half-shaft 50, and applying force to the knocking block 40 so that the knocking block 40 moves along the direction of the guide rod 10 toward the limiting assembly 30 until the knocking block 40 applies a force to the limiting assembly 30 and transmits the force well to the guide rod 10, and finally applying force to the rear axle half-shaft 50 through the docking assembly 20, thereby removing the rear axle half-shaft 50 from the rear axle assembly. The utility model has a simple structure and is easy to use, and effectively reduces the difficulty of disassembling the rear axle half-shaft 50.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
