[0002] A milling cutter is a rotating cutter with one or more cutting teeth used for milling machining. In the production and manufacturing process, the coating on the surface of the milling cutter plays a crucial role in the cutting performance and service life of the milling cutter, that is, milling cutter coating. The diamond coating is a coating grown on the metal surface by introducing a certain amount of mixed gas of hydrogen and methane and using the elevated temperature generated by hot wire heating to produce a reaction; the control of temperature greatly affects the diamond growth rate. In the prior art, when fixing and installing the milling cutter and the hot wire, manual measurement of the distance between the hot wires is used and then wire hanging is carried out. This is prone to measurement errors and inaccuracies, resulting in a certain deviation in the distance, leading to uneven distribution of the hot wires and uneven heating of the milling cutter installed below the heat, and at the same time, the manual efficiency is low during the batch installation and testing of milling cutters, affecting the production work efficiency. Summary of the Utility Model

[0018] The present utility model will be further described below by way of embodiments, but the present utility model is not limited to the scope of the described embodiments.

[0019] Embodiment

[0020] As Figure 1-2 shown, the present embodiment provides a limiting and fixing device for a milling cutter tooling. The limiting and fixing device includes: a bottom plate 1, a workbench 2, an electrode rod 3, and a limiting wheel shaft 4. The workbench 2 is installed on the bottom plate 1, and the workbench 2 is used for placing the milling cutter 7; the electrode rod 3 is arranged on both sides of the workbench 2, the limiting wheel shaft 4 is installed on the electrode rod 3, and the groove 10 is arranged on the limiting wheel shaft 4.

[0021] In this embodiment, the limit fixing device includes a plurality of limit wheel shafts 4, and the plurality of limit wheel shafts 4 are equidistantly distributed on the electrode rod 3. Specifically, there are two electrode rods 3, which are respectively arranged on both sides of the workbench 2. The two ends of the electrode rod 3 are respectively mounted on the electrode columns at both ends. There are four electrode columns, two on each side of the workbench 2. The electrode columns are connected to a power controller to energize the electrode rod 3 to heat the heating wire 5. The two electrode rods 3 are symmetrically distributed on both sides of the workbench 2, and notches are symmetrically arranged thereon for installing the limit wheel shafts 4. The limit wheel shafts 4 are installed and clamped in the notches at equal intervals according to the placement of the milling cutter 7 to ensure that the limit wheel shafts 4 always remain in the same position, reducing the time required for manual measurement when placing the heating wire 5 subsequently and improving the production work efficiency.

[0022] In this embodiment, the limit fixing device includes a plurality of heating wires 5, and the two ends of the heating wires 5 are respectively wound around the grooves 10 on both sides. Specifically, grooves 10 are provided on each limit wheel shaft 4 for winding the heating wires 5, so that the heating wires 5 can be better fixed in the same position; since the limit wheel shafts 4 are arranged at equal intervals, the intervals between the heating wires 5 wound on the electrode rod 3 can also remain unchanged all the time, ensuring that the heat generated by the heating wires 5 is evenly distributed, thereby improving the uniformity of the milling cutter, reducing the errors caused by manual operation, and improving the production work efficiency.

[0023] In this embodiment, the limit fixing device further includes a milling cutter graphite disk 6, a positioning pin 8 and a limit pin 9. The milling cutter graphite disk 6 is arranged at the exact middle position of the workbench 2, and the positioning pin 8 and the limit pin 9 are respectively arranged around the milling cutter graphite disk 6 for limiting and fixing the milling cutter graphite disk 6. Specifically, the number of limit pins 9 is 4, and the 4 limit pins 9 are evenly distributed on both sides of the milling cutter graphite disk 6; the positioning pin 8 is arranged at the front end of the milling cutter graphite disk 6. By installing the positioning pin at the front end of the milling cutter graphite disk 6, the specific position of the milling cutter graphite disk 6 on the workbench 2 can be determined. By additionally installing the limit pins 9 on both sides, the milling cutter graphite disk 6 can be prevented from moving left and right, and can be better fixed on the workbench 2. At the same time, during batch installation and testing, the installation and placement time of the milling cutter graphite disk 6 is reduced, and it is not necessary to measure the specific position of the milling cutter graphite disk 6 again and again, thereby ensuring that the milling cutter 7 inserted on the milling cutter graphite disk 6 is stably placed to ensure better heating.

[0024] This embodiment provides a limit fixing device for a milling cutter tooling. The limit fixing device fixes the milling cutter graphite disk through a plurality of limit pins, enabling the milling cutter graphite disk to be well fixed in the same position without affecting the installation test. By installing a number of limit wheel shafts on the electrode rod around which the hot wire is wound, and precisely arranging the limit wheel shafts at equal intervals, with a groove provided on each limit wheel shaft, and winding the hot wire in the groove, an equal-distance distribution of the hot wire spacing can be achieved, thereby realizing uniform heating of the milling cutter, reducing cumbersome manual measurement steps, and improving the efficiency of production work.

[0025] The working principle of the present utility model is as follows: Positioning pins 8 and limit pins 9 are installed on the workbench 2 so that the milling cutter graphite disk 6 can be fixed in the same position. Then, according to the placement of the milling cutter 7, notch openings are equidistantly provided on the electrode rods 3 on both sides of the workbench for installing the limit wheel shafts 4. The limit wheel shafts 4 are designed with grooves 10 for winding the hot wire 5, and the hot wires 5 are arranged side by side at equal intervals. During the batch installation test of the milling cutter 7, it is not necessary to measure the position of the milling cutter graphite disk 6 multiple times and manually measure the spacing of the hot wires 5, reducing manual measurement errors and improving the efficiency of production work.

[0026] Although the specific implementation manners of the present utility model have been described above, those skilled in the art should understand that this is only for illustration purposes. The protection scope of the present utility model is defined by the appended claims. Without departing from the principles and essence of the present utility model, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the present utility model.
