[0032] like Figures 1-5 As shown, this invention proposes a single-crystal guide wheel double V grooving tool device, including a grooving tool. The grooving tool includes a tool rod 1, a tool head 2 is provided at one end of the tool rod 1, and a blade 3 is installed at the end of the tool head 2 away from the tool rod 1. An annular mounting groove 6 is recessed on the tool rod 1, and a chip removal groove 4 is recessed on the upper side of the tool head 2. The lower side of the tool head 2 is an inclined surface, and the upper side is an arc-shaped curved surface. The angle between the inclined surface and the vertical surface is α, and the central angle corresponding to the arc-shaped curved surface is β.

[0033] The grooving tool is assembled onto the cutter head mechanism, which includes a mounting plate 7 and a mounting cover 8. The mounting plate 7 and the mounting cover 8 are connected by connecting bolts. The mounting plate 7 has several annular mounting grooves 18 recessed in a ring.

The tool rod 1 is inserted into the annular mounting grooves 18, and the limiting semi-rings 20 are engaged with the annular mounting grooves 26.

[0034] The curved surface of the blade head 2 is also recessed with an inlay groove 5, and the blade 3 is mounted on the inlay groove 5;

[0035] The insert groove 5 facilitates the quick installation and fixation of the blade 3.

[0036] A central post 10 is provided in the middle of the mounting plate 7, and a central groove 13 is recessed on the mounting cover 8. The central post 10 is inserted into the central groove 13.

[0046] The angle of α is 22°-45°, and the angle of β is 55°-80°.

[0047] The grooving tool has a V-shape in both its front and top views, hence it is a double V grooving tool.

[0048] The specific implementation method is as follows: the grooving tool is installed on the cutter head mechanism, the cutter head mechanism is connected to the power rotation structure of the machine tool, the power rotation structure of the machine tool controls the rotation of the cutter head mechanism, so that the grooving tool on the cutter head mechanism can cut and groove the single crystal guide wheel. During this process, the connecting bolt passes through the mating groove 12 and the mating column 11 to connect the mounting plate 7 and the mounting cover 8.

[0049] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
