[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] (1) In the present invention, during use, the differential housing to be processed is fixedly arranged on the top of the carrier plate through an existing fixture. By rotating and adjusting the adjusting tube, the second linkage plate gradually approaches or moves away from the first linkage plate. Then, by rotating the first limiting rod and the second limiting rod, the limiting block can drive the limiting strip to closely adhere to both sides of the carrier plate, so as to simultaneously fix and limit the positions of multiple differential housings to be processed. Furthermore, by controlling and starting the rotating motor, the rotating motor can drive the linkage gear to rotate in cooperation with the linkage shaft. Subsequently, the linkage gear can rotate and adjust the use angle of the rotating seat in cooperation with the rotating gear ring. Then, the rotating seat can rotate and adjust the use direction of the extension frame in cooperation with the moving frame. Thus, the extension frame can drive the grinding machine body to be located above the differential housing to be processed in cooperation with the fixed seat. Moreover, through an existing controller device, the first driving motor, the second driving motor, and the third driving motor can be controlled and adjusted to drive the first moving rod, the second moving rod, and the third moving rod to rotate respectively. Subsequently, the rotating first moving rod, second moving rod, and third moving rod can move and adjust the moving frame, the moving bracket, and the fixed seat, so as to drive the grinding machine body to perform grinding treatment on the differential housing to be processed.

Then, by rotating and adjusting the adjusting tube, the adjusting tube can drive the second linkage plate to move in position in cooperation with the spliced adjusting rods. Thus, the first linkage plate and the second linkage plate can be located on both sides of the spliced carrier plate. Then, by rotating and adjusting the first limiting rod and the second limiting rod, the limiting block can drive the limiting strip to fit on both sides of the spliced carrier plate, so as to fix and limit the position of the spliced carrier plate, facilitating subsequent processing, enabling the equipment to meet the use of parts to be processed with different specifications, and improving the universality of the actual use of the equipment.

By rotating and adjusting the adjusting pipe 110, the second linkage plate 113 is gradually moved closer to or away from the first linkage plate 106. Then, by rotating the first limiting rod 111 and the second limiting rod 115, the limiting block can drive the limiting strip 112 to be close to both sides of the carrier plate 109, so as to fix and limit the positions of multiple differential housings to be processed simultaneously.

At the same time, by replacing different functional connectors, processing other than grinding the outer surface of the differential housing to be processed can be carried out, thereby improving the actual use efficiency of the equipment and effectively preventing the equipment from being idle;

[0035] Step 2. Function switching: After replacing different functional connectors according to actual processing requirements, and then according to the specifications of the parts to be processed, the number of carrier plates 109 is increased or decreased. At the same time, multiple adjusting rods 114 can be spliced through the connecting threaded holes.

9. The machining tool for a differential housing according to claim 8, wherein: The linkage component includes a rotating gear ring (203) and a linkage gear (204). The rotating gear ring (203) is sleeved on the outer surface of the rotating seat (202). The linkage gear (204) is sleeved on the outer surface of the linkage shaft (108). The linkage gear (204) meshes with the rotating gear ring (203).

10. A method for using a machining tool for a differential housing, characterized in that, Applied to a differential housing processing machine tool described in claim 9, it includes the following steps: S1. Grinding treatment: Fix the differential housing to be processed on the top of the carrier plate (109) through an existing fixture. By rotating and adjusting the adjusting tube (110), the second linkage plate (113) is gradually moved closer to or farther away from the first linkage plate (106). Then, by rotating the first limiting rod (111) and the second limiting rod (115), the limiting block can drive the limiting strip (112) to be close to both sides of the carrier plate (109), so as to simultaneously fix and limit the positions of multiple differential housings to be processed. Then, by controlling the start of the rotating motor (107), the rotating motor (107) and the linkage shaft (108) can drive the linkage gear (204) to rotate. Subsequently, the linkage gear (204) and the rotating gear ring (203) can rotate and adjust the use angle of the rotating seat (202). Then, the rotating seat (202) and the moving frame (207) can rotate and adjust the use direction of the extension frame (211). Then, the extension frame (211) can cooperate with the fixed seat (214) to drive the grinding machine body (215) above the differential housing to be processed. Then, through the existing controller device, the first driving motor (206), the second driving motor (209), and the third driving motor (213) can be controlled to drive the first moving rod (205), the second moving rod (208), and the third moving rod (212) to rotate respectively. Subsequently, the rotating first moving rod (205), second moving rod (208), and third moving rod (212) can move and adjust the moving frame (207), the moving frame (210), and the fixed seat (214), so as to drive the grinding machine body (215) to perform grinding treatment on the differential housing to be processed; S2. Function switching: According to the actual processing requirements, after replacing different function connectors, the number of carrier plates (109) is increased or decreased according to the actual specifications of the parts to be processed. At the same time, multiple adjusting rods (114) can be spliced through the connecting threaded holes. Then, by rotating and adjusting the adjusting tube (110), the adjusting tube (110) and the spliced adjusting rods (114) can drive the second linkage plate (113) to move in position. Then, the first linkage plate (106) and the second linkage plate (113) can be located on both sides of the spliced carrier plate (109). Then, by rotating and adjusting the first limiting rod (111) and the second limiting rod (115), the limiting block can drive the limiting strip (112) to fit on both sides of the spliced carrier plate (109), so as to fix and limit the position of the spliced carrier plate (109), which is convenient for subsequent processing.
