[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1-4 As shown, a drive axle housing processing tool includes a cutter disc 1, which is arranged in a disc shape. A mounting groove 2 is opened on the cutter disc 1, and the mounting groove 2 is arranged along the diameter direction of the cutter disc 1. The rotation center of the cutter disc 1 is located on the straight line where the center line of the mounting groove 2 is located. A blade 4 is installed on the mounting groove 2, and the blade 4 can slide along the length direction of the mounting groove 2. The blade 4 has a top cutter head 41 and side cutter heads 42 on both sides. A pushing component 3 is installed on the cutter disc 1, and the pushing component 3 is used to make the blade 4 slide along the extension direction of the mounting groove 2, so that the blade 4 has different processing diameters when rotating. The blade 4 is detachably installed on the pushing component 3, and a chamfering tool 5 is installed on the blade 4, and the blade of the chamfering tool 5 and the blade of the side cutter head 42 are in the same plane.

[0023] In a specific embodiment of the utility model, a driving element is connected to the cutter disc 1 to drive the cutter disc 1 to rotate. Preferably, the driving element is a servo motor, etc. When the driving element drives the cutter disc 1 to rotate, a groove is made on the drive axle housing 1. When the blade 4 is installed, the blade 4 is placed in the installation groove 2 and fixed on the pushing component 3, and the blade 4 is driven to slide in the installation groove 2 by the pushing component 3. When the blade 4 slides to different positions of the installation groove 2 and when the blade 4 rotates, grooves of different sizes can be opened on the drive axle housing. By setting a detachable blade 4, the blade 4 can be easily replaced after it is worn. At the same time, a chamfering knife 5 is set on the blade 4. Since the blade of the chamfering knife 5 and the blade of the side cutter head 42 are in the same plane, a chamfer with a certain angle can be opened on the groove, and the inclination of the chamfer can be adjusted by adjusting the inclination angle of the chamfering knife 5.

[0024] In a specific embodiment of the present utility model, the cutter disc 1 is installed on a driving member, and the rotation center of the driving member coincides with the rotation center of the cutter disc 1; the driving member drives the cutter disc 1 to rotate and then drives the cutter disc 1 to rotate, and the rotation of the cutter disc 1 drives the tool to groove the drive axle housing.

[0025] Preferably, the width of the mounting groove 2 is adapted to the bottom width of the blade 4 ; when the blade 4 is inserted into the mounting groove 2 , loose clamping of the blade 4 and shaking thereof are avoided.

[0026] In a specific embodiment of the utility model, the pushing assembly 3 includes a mounting block, which is detachably connected to the blade 4, and a threaded rod is threadedly connected to the mounting block. A connecting block 33 is fixedly arranged on the cutter disc 1, and the threaded rod and the connecting block are rotatably connected. When the threaded rod rotates, only relative rotation occurs between the threaded rod and the connecting block; when the processing radius of the tool is changed, the connection block and the threaded rod are driven to rotate relative to each other through the rotation of the threaded stem, and the connecting block slides along the length direction of the mounting groove 2. When the blade 4 is away from the rotation center of the cutter disc 1, the processing radius ratio of the blade 4 becomes larger, so that slots of different sizes can be processed on the drive axle housing.

[0027] Preferably, the end of the threaded rod 32 away from the mounting block is fixedly provided with a friction groove; the friction groove facilitates the operator to rotate the threaded rod.

[0028] Specifically, a plug plate is fixedly provided on the blade 4, a vertical opening 34 is provided on the connection block, and a screw 36 is connected between the opening 34 and the plug plate 35; in order to facilitate the replacement of the tool, when the tool is worn after being used for a period of time, the connection block is disengaged from the plug plate by turning the screw, and the blade 4 can be removed at this time. When replacing a new blade 4, the new blade 4 is inserted into the installation slot 2 and the connection block is located in the opening, and then the plug plate is fixed in the opening by the screw.

[0029] In a preferred embodiment of the utility model, an L-shaped slot 61 is provided on the blade 4, and the two ends of the chamfering knife 5 can slide on both sides of the L-shaped slot 61 respectively. Slots 62 are provided at both ends of the chamfering knife 5, and bolts 63 are installed in the slots 62 for fixing the chamfering knife 5 at different positions of the L-shaped slot 61; when installing the chamfering knife 5, the bolts 63 are rotated so that the two ends of the chamfering knife 5 can slide in the L-shaped slot 61. After the chamfering knife 5 is adjusted to a suitable position, the chamfering knife 5 is fixed by the bolts 63. After the blade 4 processes the drive axle housing to a certain depth, the chamfering knife 5 chamfers the slot processed by the blade 4. While the blade 4 is processing the slot, the chamfering knife 5 can chamfer the slot at the same time, which is convenient and quick.

[0030] Specific working principle: The rotation of the cutter disc 1 drives the blade 4 to rotate and then process the drive axle housing. The position of the blade 4 on the cutter disc is adjusted by pushing the component 3. The farther the blade 4 is from the rotation center of the cutter disc 1, the wider the groove that can be processed is. By setting a chamfering tool 5, when processing the groove, the groove can be chamfered at the same time. The position of the chamfering tool 5 can adjust the chamfering angle. By disassembling the blade 4, the blade 4 can be easily replaced.
