[0002] The differential is a key component in modern automobiles and mechanical transmission systems, responsible for adjusting the speed difference between the drive wheels during cornering to provide better handling and driving stability. The differential housing is a key structural component of the differential, and the machining quality of its interior directly affects the performance and reliability of the differential.

[0003] When processing the interior of the differential housing, it is often necessary to place the processing assembly into the housing from the side opening of the housing; at the same time, the differential housing needs to be positioned and fixed during processing; during the processing, it is often necessary to rotate and adjust the position of the housing so that the processing assembly can be placed into the housing from the other side opening to process the interior; however, when rotating the housing, it is often necessary to release the positioning and fixing state of the housing, and after rotating it to the appropriate position, re-position and re-fix the housing, which is very troublesome and reduces work efficiency. To address the above problems, a new processing device is needed. Utility Model Content

[0004] The technical problem to be solved by the present invention is that during the process of machining the inner cavity of a differential housing, when the housing needs to be rotated, the fixation needs to be released and the housing needs to be repositioned and fixed, which affects the machining efficiency.

[0010] Beneficial effects of the utility model:

[0011] 1. A locating frame is rotatably installed within the groove, located below the mounting plate.

[0020] By providing a positioning frame 9 and a positioning rod 14 that can rotate under the drive of the rotating structure, the shell can be quickly rotated without changing the positioning and fixing state of the shell, thereby improving work efficiency; at the same time, the vacuum cleaner 7 can be used to absorb dust from under the shell to reduce dust dispersion.

[0021] like Figure 2 As shown, the rotating structure includes a rotating motor 11 and a rotating shaft. The rotating motor 11 is located within the groove 8. The rotating shaft is fixedly connected to the output shaft of the rotating motor 11 and is also fixedly connected to the positioning frame 9. The rotating motor 11 facilitates the control of the differential's rotation. Each time the rotating motor 11 is activated, it drives the positioning frame 9 to rotate 180°, aligning the other side opening of the differential case 5 with the working assembly 6.

[0022] A rotating block 13 is rotatably provided inside the fixed plate 4, and the rotating block 13 presses on the differential housing 5; the rotating block 13 contacts the differential housing 5, and when the differential housing 5 rotates, the setting of the rotating block 13 can greatly reduce the friction between the differential housing 5 and the fixed plate 4.

[0023] The vacuum cleaner 7 is connected to the positioning frame 9 via a connecting pipe 12 , and the connecting pipe 12 is a sufficiently long hose that can ensure normal connection between the vacuum cleaner 7 and the positioning frame 9 when the differential housing 5 rotates.

[0025] Principle of the utility model

[0026] like Figure 4As shown, when machining the differential housing 5, first place the differential housing 5 above the positioning frame 9, insert the positioning rod 14 into the mounting hole 16, and quickly position the differential housing 5. Simultaneously, the connecting tube 17 is located within the positioning frame 9. The hydraulic rod 3 is activated, causing the fixing plate 4 to move downward and press against the differential housing 5, completing the positioning and fixing of the differential housing 5. The working assembly 6 is then activated, extending from the side opening into the differential housing 5 to machine the interior of the differential housing 5. Simultaneously, the vacuum cleaner 7 is activated, using the connecting tube 12 to draw dust from the positioning frame 9 and the connecting tube 17 into the differential housing 5.

[0027] When the differential housing 5 needs to be rotated, the working assembly 6 is first returned to its original position, and the rotating motor 11 is directly started. Driven by the rotating shaft, the positioning frame 9 drives the positioning rods 14 to rotate. Under the action of the two positioning rods 14, the differential housing 5 rotates accordingly. At this time, there is no need to change the clamping state of the fixed plate 4. The setting of the rotating block 13 can greatly reduce the friction between the differential housing 5 and the fixed plate 4, making the rotation of the differential housing 5 smoother. After the differential housing 5 is rotated to the appropriate position, the working assembly 6 is inserted into the other side opening of the housing to process the interior of the housing. Therefore, when the direction of the differential housing 5 is changed, the positioning and fixing state of the differential housing 5 are not changed, which greatly improves the processing efficiency.

[0028] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
