Drawings

FIG. 1 is an external structural view of the present invention;

FIG. 2 is a cross-sectional view of the present invention;

in the figure: the device comprises a base 1, a speed reducing motor 2, a rotary frame 3, a gear box 4, a support seat 5, a cutter head 6, a transmission shaft 7, a main shaft 8, a bevel gear 9, a coupler 10 and a cylindrical gear 11.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the universal externally tangent milling head comprises a base 1 and a speed reducing motor 2, wherein the front end of the speed reducing motor 2 is connected to one side of the base 1; the rotary frame 3 is provided with scales and is arranged on the other side, far away from the speed reducing motor 2, of the base 1, and the whole rotary frame 3 can rotate freely; the gearbox is characterized by further comprising a gearbox 4, a supporting seat 5 and a cutter head 6, wherein the gearbox 4 is fixed on the rotary frame 3, and the cutter head 6 and the supporting seat 5 are installed on the gearbox 4; the inside transmission shaft 7 that still includes of frame 1, transmission shaft 7 runs through frame 1, with gear motor 2 links to each other. When a workpiece needs to be machined from multiple sides, the rotary frame 3 can drive the gear box 4, the supporting seat 5 and the cutter head to rotate and fix at multiple angles.

The gearbox is characterized by further comprising a main shaft 8 and a bevel gear 9, wherein the bevel gear 9 is installed inside the gearbox 4, and the main shaft 8 is connected with the transmission shaft 7 through the bevel gear 9. The main shaft 8 penetrates through the supporting seat 5 and the gear box 4, and the cutter head 6 is installed on the gear box 4 through the main shaft 8. The speed reducing device further comprises a coupler 10, wherein the coupler 10 is connected with the transmission shaft 7 and the speed reducing motor 2; the transmission shaft 7 and the bevel gear 9 are also connected by the coupling 10.
