Technical Field

[0001] This utility model relates to the field of nut manufacturing technology, specifically to auxiliary tooling for milling the outer wall of a nut. Background Technology

[0002] Nuts are common connecting parts. Some large mechanical equipment requires the use of oversized nuts. In the production and processing of such nuts, it is usually necessary to first machine the center hole, then machine the outer hexagonal face, and finally machine the internal thread in the center hole. Currently, the outer hexagonal face is mainly machined by milling machine. During the machining process, the center hole is supported by tooling. However, the existing tooling can only be used to machine a single nut at a time, resulting in low processing efficiency. Utility Model Content

[0015] like Figure 1-4 As shown, this embodiment is an auxiliary tooling for milling the outer wall of a nut, including a support frame 1. The bottom of the support frame 1 is provided with a fastening hole 2 for connection with a milling machine. A rotating shaft 5 is mounted on the upper end of the support frame 1. The rotating shaft 5 is rotatably connected to the support frame 1 through a bearing. One end of the rotating shaft 5 is connected to a reducer 4. The input end of the reducer 4 is equipped with a servo motor 3. The other end of the rotating shaft 5 extends outward and is connected to a support rod 9. A section of smooth rod is provided on the support rod 9. The smooth rod is used to place the nut to be processed. The outer diameter of the smooth rod matches the diameter of the center hole of the workpiece 8. Each end of the smooth rod is provided with a thread. The diameter of the thread is smaller than that of the smooth rod. The thread is used to install a locking nut 7. The size of the locking nut 7 is smaller than that of the workpiece 8. The workpiece 8 is clamped from both ends by the two locking nuts 7.

[0016] Furthermore, a coupling 6 is installed between the rotating shaft 5 and the support rod 9. The support rod 9 is available in various specifications according to its diameter, so as to be compatible with the corresponding nut to be processed.

[0017] Furthermore, the support rod 9 has a clamping part at one end away from the rotating shaft 5, which is used for clamping by the jaw chuck 10 of the milling machine.

[0018] Furthermore, the reducer 4 is a worm gear reducer 4 with a locking function.

[0019] Furthermore, the rotating shaft 5 is connected to an angle sensor, which is used to detect the rotation angle of the rotating shaft 5. The angle sensor is connected to the servo motor 3 via a signal.

[0020] The working principle of this utility model is as follows: A support rod 9 of appropriate specification is selected according to the diameter of the center hole of the nut to be processed. Several workpieces 8 to be processed are inserted onto the support rod 9 at one time. Locking nuts 7 are then installed at both ends of the support rod 9, securing the workpieces 8 to the support rod 9 with the two locking nuts 7. One end of the support rod 9 is then fixedly connected to the rotating shaft 5 via a coupling 6, and the other end is clamped by the chuck 10 of the milling machine. The support frame 1 is then fixedly connected to the milling machine table. Milling can then begin, with the milling cutter processing one side of the outer hexagonal surface of each workpiece 8 at a time. After machining one side, the chuck 10 is released first. Then, the servo motor 3 drives the rotating shaft 5 to rotate 60° via the reducer 4. During the rotation, the angle sensor detects the rotation angle of the rotating shaft 5 in real time. When it reaches 60°, a signal is sent to the servo motor 3 to stop. At this time, the rotating shaft 5 cannot rotate due to the self-locking effect of the worm gear reducer 4, thus stabilizing the workpiece 8 at the current angle. After adjusting the angle, the support rod 9 is clamped again by the chuck 10, and then the second side can be milled. After multiple rotations and angle adjustments, the machining of the outer hexagonal surface can be completed. In the entire machining process, multiple workpieces 8 only need to be clamped once, thus improving machining efficiency.
