[0050] The following will combine the accompanying drawings and, through specific embodiments and their application scenarios, provide a detailed description of the server provided by the embodiments of this application.

[0051] Embodiment 1:

[0052] As Figure 1 、 Figure 2 shown, the embodiment of this application provides a thread rolling device for a drive shaft, including a machine tool body 1, a slide table 2, and a thread rolling mounting seat 3, and further including: a mounting plate 4, which is fixedly connected between the slide table 2 and the thread rolling mounting seat 3; a plurality of thread rolling plates 5, which are respectively detachably mounted on the thread rolling mounting seat 3; wherein, the thread rolling mounting seat 3 is rotatably adjustable and mounted on the thread rolling mounting seat 3, and the thread rolling mounting seat 3 is provided in a hexagonal prism shape.

[0053] Furthermore, it further includes a plurality of adjustment holes 6, which are distributed in an arc array at one end of the thread rolling mounting seat 3; a locking hole 7, which is provided on the mounting plate 4; wherein, the locking hole 7 is connected to the adjustment hole 6 through a fastener.

[0054] In this embodiment of this application, due to the above structure, the workpiece is installed in the machine tool body 1, and the motor drives the upper / lower slide table 2 to drive each thread rolling mounting seat 3 to move, and the upper / lower thread rolling mounting seats 3 move towards the middle respectively, so as to perform thread rolling work on the workpiece. When it is necessary to change the tooth type of the thread rolling, the thread rolling mounting seat 3 is provided in a hexagonal prism shape, and three thread rolling plates 5 are respectively installed on the thread rolling mounting seat 3, and the tooth types of the three thread rolling plates 5 are different. When switching the tooth type, first unscrew the fasteners (such as screws, bolts, pins, etc.) of the mounting plate 4 and the thread rolling mounting seat 3, so that the connection relationship between the adjustment hole 6 and the locking hole 7 is lost, and then rotate the thread rolling mounting seat 3. The thread rolling mounting seat 3 rotates along the mounting plate 4. When the required thread rolling plate 5 is rotated to the processing end, lock the corresponding adjustment hole 6 above the thread rolling plate 5 at the processing end and the locking hole 7 through a fastener to ensure the fixation between the mounting plate 4 and the thread rolling mounting seat 3. Through the setting of the thread rolling mounting seat 3 and multiple thread rolling plates 5, different tooth types can be adjusted, and the use range of the machine tool body 1 can be improved.

[0055] Example 2:

[0056] As Figures 1 to 3 shown, in this embodiment, in addition to including the structural features of the foregoing embodiment, it further includes: a slot 8, which is arranged on the mounting surface of the gear hobbing mounting seat 3; a bump 9, which is arranged at the mounting end of the gear hobbing plate 5 and is inserted into the slot 8; a limiting groove 10, which is arranged on the bump 9; a fixing component 11, which is mounted on the gear hobbing mounting seat 3 and is connected to the limiting groove 10.

[0057] Furthermore, the fixing component 11 includes a sliding groove 12, which is arranged on one inner wall of the slot 8; a limiting block 13, which is slidably mounted in the sliding groove 12; a connecting rod 14, which passes through one end of the gear hobbing mounting seat 3 and is fixedly connected to the limiting block 13; a spring 15, which is sleeved outside the connecting rod 14 and is fixedly connected between the sliding groove 12 and the limiting block 13; wherein, the limiting block 13 can be slidably mounted into the limiting groove 10.

[0058] Furthermore, it further includes a support plate 16, which is fixedly connected to the outer end of the connecting rod 14 and is attached to the side wall of the gear hobbing mounting seat 3; a pull ring 17, which is fixedly connected to the outer end of the support plate 16.

[0059] In this embodiment of the present application, due to the adoption of the above structure, when it is necessary to disassemble the gear hobbing plate 5 from the gear hobbing mounting seat 3, pull the pull ring 17 outwards, the support plate 16 drives the connecting rod 14 to move outwards. At the same time, the spring 15 is compressed, and the limiting block 13 moves from the limiting groove 10 into the sliding groove 12, so that there is no fixed relationship between the bump 9 and the slot 8, and then the bump 9 can be removed from the slot 8, and at this time the gear hobbing plate 5 is separated from the gear hobbing mounting seat 3. When it is necessary to install the gear hobbing plate 5 onto the gear hobbing mounting seat 3, first insert the bump 9 into the slot 8, and then loosen the pull ring 17, the support plate 16 is attached to the outer wall of the gear hobbing mounting seat 3. At this time, the spring 15 is reset, the spring 15 pushes the limiting block 13 inwards, the limiting block 13 moves along the sliding groove 12 and moves into the limiting groove 10, and the limiting block 13 is installed between the limiting groove 10 and the sliding groove 12, effectively limiting the bump 9 and fixing between the gear hobbing plate 5 and the gear hobbing mounting plate 4.

[0060] Example 3:

[0061] As Figure 1 、 Figure 4 shown, in this embodiment, in addition to including the structural features of the foregoing embodiment, it further includes: a pair of cleaning components 18, which are respectively mounted on the machine tool body 1; wherein, the pair of cleaning components 18 are distributed on both sides of the machining center of the machine tool body 1.

[0062] Further, the cleaning component 18 includes a driving motor 19 fixedly installed on the outer wall of the machine tool body 1; a rotating shaft 20 fixedly installed at the output end of the driving motor 19; a brush 21 disposed on the rotating shaft 20; and a visual detector 22 disposed on the inner wall of the machine tool body 1. Wherein, the visual detector 22 is electrically connected to the driving motor 19.

[0063] In this embodiment of the present application, due to the above structure, when the workpiece is installed on the machining position of the machine tool body 1, the camera of the visual detector 22 detects the workpiece, and transmits the signal indicating that the workpiece installation is completed to the driving motor 19. The driving motor 19 starts, drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the brush 21 to rotate together. During the process of the sliding table 2 driving the gear hobbing mounting plate 4 to move, the brush 21 contacts the tooth surface of the gear hobbing plate 5, effectively cleaning the debris remaining in the teeth of the gear hobbing plate 5 and ensuring the machining accuracy of the workpiece.
