Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] A differential assembly cleaning device comprises a processing table 1, on which a differential assembly is arranged, wherein the differential assembly comprises a main reduction gear 2, in which an internal bevel gear 3 is installed, and a sealing device 4, a transmission device 5 and a vacuum drying box 6 are arranged on the processing table 1.

[0028] like Figure 1The vacuum drying oven 6 is a prior art. After the differential assembly is cleaned, the differential assembly can be placed in the vacuum drying oven 6 for vacuum drying. The main reduction gear 2 undergoes grinding in the pre-process. The sealing device 4, the transmission device 5 and the vacuum drying oven 6 are sequentially installed. The bearing plate 7 and the differential assembly can be transferred manually or by external mechanical equipment. The first fixing frame 41 is fixed above the processing table 1.

[0029] The closure cover 46 and the plug 47 are respectively arranged on both sides of the differential assembly, the plug 47 is adapted to the internal bevel gear 3, one end of the closure cover 46 is in conflict with one side of the main reduction gear 2, and a sealing ring 48 is fixedly connected to one end of the closure cover 46 close to the main reduction gear 2.

[0030] like Figure 2 , Figure 3 and Figure 5 When the plug 47 is close to the differential assembly, one end of the main reduction gear 2 can be blocked. When the closing cover 46 is close to the differential sensor assembly, it can be attached to one side of the main reduction gear 2 to close the internal bevel gear 3 located in the main reduction gear 2 from the side.

[0031] The transmission device 5 includes a driving motor 51 , a fixing plate 52 and a second fixing frame 53 . A fixing pipe 54 is fixedly connected to the second fixing frame 53 . A rotating shaft 55 is rotatably connected to the fixing pipe 54 . One end of the rotating shaft 55 is fixedly connected to a driving shaft 56 .

[0032] like Figure 1 and Figure 4 The driving motor 51, the fixing plate 52 and the second fixing frame 53 are all fixed on the processing table 1. The driving shaft 56 has a hole and can be installed together with the internal bevel gear 3 by clamping or bolting. A flushing mechanism 8 is also provided on both sides of the transmission device 5 on the processing table 1.

[0033] The output end of the driving motor 51 is fixedly connected with a driving gear 57 . The end of the rotating shaft 55 away from the driving shaft 56 penetrates the fixing plate 52 and is fixedly connected with a linkage gear 58 . The linkage gear 58 is meshed with the driving gear 57 .

[0034] like Figure 4 Linkage gears 58 are provided on both sides of the driving gear 57, so that when the driving motor 51 drives the driving gear 57 to rotate, the driving gear 57 can drive the linkage gears 58 on both sides to rotate.

[0035] A bearing plate 7 is disposed below the main reduction gear 2 , and a bottom bracket 701 and a side limit bracket 702 are fixedly connected to the top of the bearing plate 7 .

[0036] like Figure 5There is a trapezoidal opening on the bottom bracket 701, so that the bottom of the main reduction gear 2 can be located at the trapezoidal opening of the bottom bracket 701, and the side limiting frame 702 can limit the main reduction gear 2 from one side.

[0037] The processing table 1 is provided with a flushing mechanism 8 on both sides of the main reduction gear 2, and the flushing mechanism includes a support plate 81, a shunt pipe 82 is fixedly connected to the support plate 81, a plurality of high-pressure nozzles 83 are fixedly connected to one side of the shunt pipe 82, an input pipe 84 is fixedly connected to one side of the shunt pipe 82, and a solenoid valve 85 is fixedly installed on the input pipe 84.

At this time, the solenoid valve 85 is opened, and the external pump inputs the external water source into the shunt pipe 82 through the input pipe 84, and then sprays it out from the high-pressure nozzle 83 to wash away the dust or waste generated by the grinding.

[0041] After the grinding gear flushing is completed, the solenoid valve 85 is closed, and the telescopic cylinder 42 is contracted, so that the closing cover 46 and the plug 47 are away from the differential assembly. At this time, the differential assembly can be transferred and fixed to the drive shaft 56, and the drive motor 51 drives the drive gear 57 to rotate, and the drive gear 57 drives the linkage gear 58 to rotate, and the linkage gear 58 drives the rotating shaft 55 and the drive shaft 56 to rotate, and the flushing mechanism 8 on both sides cleans the differential assembly.

[0042] Compared with the related art, the differential assembly cleaning device provided by the utility model has the following advantages:

[0043] Beneficial effects:

[0044] The utility model uses a plug 47 and a sealing cover 46 to respectively seal the two sides of the main reduction gear 2 when the differential assembly is roughly cleaned after the gear grinding, so as to protect the inside of the washed differential assembly and expose only the surface of the main reduction gear, thereby preventing the gear grinding pollutants from entering the inside of the differential and ensuring the cleanliness of the differential assembly. Then, the differential assembly after the rough cleaning is transferred and fixed to the drive shaft 56, and the drive shaft 56 is used to drive the differential assembly to rotate, so as to quickly complete the cleaning of the outside and inside of the differential assembly, and finally, a vacuum drying box 6 is used to complete the drying of the cleaned differential assembly.
