[0002] The differential housing is a key component in the automotive transmission system, and the machining accuracy of its end face (usually referring to the end face) directly affects the assembly quality and operational stability of the differential. Currently, the machining of the differential housing end face mainly consists of two processes: grinding and chamfering. Due to the irregular shape of the differential housing, special fixtures or specific machining equipment are often required.

[0015] This specific embodiment is a differential housing end face machining device, the structural schematic diagram of which is shown below. Figures 1-6 As shown, the machine includes a machining table 1. The top surface of the machining table 1 near the left side is a fixture mounting area 2. An annular plate 3 is provided on the upper side of the machining table 1 near the right side. A rotating plate 4 is rotatably connected to the inner side of the annular plate 3. A connecting column 5 is fixedly connected to the center of the left side wall of the rotating plate 4. A grinding wheel 6 is sleeved on the side wall of the connecting column 5. A nut 7 is threadedly connected to the side wall of the connecting column 5. A limit groove 8 is opened on the top surface of the machining table 1 near the right side. A housing 9 is slidably connected in the limit groove 8. A driving component is provided at the bottom of the housing 9. A support shaft 10 is fixedly connected to the side wall of the annular plate 3 near the lower side. The bottom end of the support shaft 10 passes through the housing 9 and is rotatably connected to it. A rotating component is provided inside the housing 9. A transmission component and a chamfering component are provided on the right side wall of the annular plate 3.

[0016] Specifically, the driving component includes any one of an electric telescopic rod, a linear motor, or an electric slide rail, mainly used to drive the horizontal movement of the annular plate 3. However, this part is not the focus of this solution, so the driving component is not described in detail.

[0017] like Figure 5 As shown, a worm gear 12 is fixedly connected to the side wall of the support shaft 10 inside the housing 9. A worm 13 is meshed on one side of the worm gear 12. A first motor 11 is installed inside the housing 9. The output shaft of the first motor 11 is fixedly connected to the worm 13, and the other end of the worm 13 is rotatably connected to the inner wall of the housing 9.

[0018] The worm gear 12 and worm 13 have a self-locking mechanism. When the support shaft 10 drives the rotating plate 4 to rotate to a suitable angle, it will not deviate even if it is subjected to external force. At the same time, it can prevent the vibration generated by the second motor 15 during operation and the resulting displacement deviation, thus ensuring the stability of the grinding and chamfering process.

[0019] like Figure 2 river Figure 6 As shown, the transmission assembly includes a mounting plate 14 fixedly connected to the top surface of the housing 9. A second motor 15 is fixedly mounted on the side wall of the mounting plate 14. A gear 16 is fixedly connected to the output shaft of the second motor 15. A ring rack 17 is fixedly connected to the right side wall of the rotating plate 4. The gear 16 meshes with the ring rack 17.

[0020] The transmission method using gear 16 and ring rack 17 can only drive the rotating plate 4 to rotate rapidly inside the ring plate 3, thereby driving the grinding wheel 6 to grind the differential end face. It should be noted that during the rotation of the rotating plate 4, since the wire of the electric push rod 18 can be stored inside the rotating plate 4, the wire of the electric push rod 18 will not be tangled when the rotating plate 4 rotates.

[0021] like Figure 2 As shown, the chamfering assembly includes an electric push rod 18 fixedly installed on the side wall of the rotating plate 4. The telescopic end of the electric push rod 18 is fixedly connected to a mounting base 19, and a cutting tool 20 is detachably connected to the mounting base 19.

[0022] The tool 20 and the mounting base 19 are connected by bolts, which is simple in structure, highly stable, and easy to replace different models of tool 20. The tool 20 is preferably inclined to facilitate the chamfering of the differential end face. In addition, by controlling the extension length of the electric push rod 18, it can adapt to differential end faces of different diameters, which is highly flexible.

[0023] like Figure 4 As shown, the connecting column 5 has a cavity inside, and several water outlet holes 22 are formed on the side wall of the connecting column 5. The rotating plate 4 has a flow guide channel 21 on its side wall, which communicates with the cavity. A connector 23 is fixedly connected to the side wall of the annular plate 3, and the connector 23 communicates with the flow guide channel 21. The water outlet holes 22 are distributed at an angle.

[0024] Specifically, the rotating plate 4 and the inner wall of the annular plate 3 are connected by a slider groove, and an annular drainage groove is provided on the surface of the groove. The connector 23 is connected to the annular drainage groove. When water flows into the annular drainage groove through the connector 23, it can enter the cavity through any one of the guide channels 21 and spray out from the water outlet 22, which facilitates the cooling treatment of the differential housing during the grinding process. The cooling part can be selected for use according to the grinding process.

[0025] Working principle: First, select a suitable clamp according to the differential specifications and fix it to the clamp mounting area 2 with bolts. Then, put the grinding wheel 6 on the connecting column 5 and lock it with the nut 7. Next, connect the external water pipe to the connector 23. When grinding the differential end face, first start the second motor 15. The output shaft of the second motor 15 drives the gear 16 to rotate. The gear 16 meshes with the ring rack 17 and drives the rotating plate 4 to rotate. The rotating plate 4 drives the grinding wheel 6 to rotate rapidly. At the same time, the drive component drives the housing 9 and... The annular plate 3 moves toward the differential end. When the grinding wheel 6 contacts the differential end face, grinding begins. After grinding is completed, the drive unit drives the annular plate 3 to reset and simultaneously starts the first motor 11. The output shaft of the first motor 11 drives the worm gear 13 to rotate. The worm gear 13 meshes with the worm wheel 12 and drives the support shaft 10 to rotate 180°, so that the tool 20 faces the differential end face. The drive unit drives the tool 20 to slowly approach the differential end face for chamfering, thereby realizing the integrated completion of grinding and chamfering.

[0026] All technical features in this embodiment can be freely combined according to actual needs.

[0027] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
