[0012] Figure 2 It is the side sectional view of the mounting sling (including the milling cutter head) according to the embodiment of the present invention;

[0013] Figure 3 It is the top view of the mounting sling (including the milling cutter head) according to the embodiment of the present invention. Detailed Embodiment

[0014] To make the purpose, content and advantages of the present invention clearer, the following combines the drawings and embodiments to further describe the detailed embodiment of the present invention in detail.

[0015] This embodiment provides a rotatable angle mounting sling for a spiral bevel gear milling cutter head, and its structure is as Figures 1 to 3 shown, including a connecting plate 1, a triangular bracket 2, a U-shaped connecting plate 3, a serrated angle adjusting support plate 4, a butterfly fastening nut 5, a rotating shaft 6 and an internal hexagonal fastening bolt 7.

[0016] The connecting plate 1 is a cylindrical structure with a closed top end. The edge of the bottom end of the cylinder is processed with an annular step structure, and a plurality of adjustable connecting holes corresponding to the standard mounting holes on the spiral bevel gear milling cutter head 8 are processed on the step structure. The height of the connecting plate 1 is 20-40 mm higher than the cutter head 8 after installing the milling cutter, so as to avoid interference with the cutting edge on the cutter head 8 when the sling adjusts the angle.

[0017] The two sides of the bottom ends of the U-shaped connecting plate 3 and the serrated angle adjusting support plate 4 are respectively fixed on the top surface of the connecting plate 1 through a triangular support 2. Two rotating shafts 3 respectively pass through the triangular support 2, the U-shaped connecting plate 3 and the serrated angle adjusting support plate 4, and are fixed through lock nuts, realizing the free rotation of the U-shaped connecting plate 3 and the serrated angle adjusting support plate 4 relative to the triangular support 2. The angle rotation of the sling is realized by adjusting the rotation angle of the serrated angle adjusting support plate 6. After adjusting to the appropriate angle, the serrated angle adjusting support plate 4 is tightened and fixed on the U-shaped connecting plate 3 by using a wing tightening nut 5. Finally, an internal hexagonal fastening bolt 7 is inserted into the adjustable connecting hole of the connecting plate 1 to connect the connecting plate 1 with the cutter head 8, and then it can be hoisted into the machine tool for installation by a crane. After installation, the internal hexagonal fastening bolt 7 is removed, the crane is withdrawn, and the parts are processed through the operation of the machine tool.

[0018] The angle-adjustable installation sling of the spiral bevel gear milling cutter head of the present invention can adjust the cutter head 8 to the required angle through the serrated angle adjusting support plate 4. In addition, according to actual needs, the number of serrations can be encrypted to improve the adjustment accuracy. In actual use, multi-angle adjustment can be quickly completed, which is convenient for the cutter head to be hoisted into various machine tools for processing at any time, thereby improving the speed of disassembling and installing the milling cutter head, greatly reducing the labor intensity of workers, and improving the safety of this process.

[0019] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
