[0020] Please refer to Figs. 1-3 The utility model provides an embodiment: the rotary table for milling cutter vacuum coating, including base 1, the rotary disc 2 of coaxial rotation installation in the upper portion of base 1 through second shaft 201 and a plurality of positioning seat 3 rotationally arranged at the edge of rotary disc 2 through first shaft 4, a plurality of positioning seat 3 are arranged in the circumferential array on rotary disc 2, in this embodiment, base 1 is hollow cylindrical structure, second shaft 201 is rotationally installed at the center of base 1 through bearing, and second shaft 201 extends to the inside of base 1, and during operation, the motor etc. (not shown in the drawing) that drives second shaft 201 to rotate can be arranged in the inside of base 1, and the driving mechanism arranged in the inside of base 1 can reduce the size of the whole.

[0021] In this embodiment, the bottom end of rotary disc 2 is provided with a plurality of ball bearings 11, and the ball bearings 11 are in rolling connection with the top end of base 1, and when rotary disc 2 rotates at the top end of base 1, the stability can be improved, and the abrasion can be reduced.

[0022] In the embodiment, the mounting portion 101 is horizontally arranged at the edge of the bottom end of the base 1, and a plurality of mounting holes are arranged through the mounting portion 101, so that the base 1 can be fixed at the working site by bolts.

[0023] In the embodiment, the positioning seat 3 is a vertical tubular structure, and a plurality of openings 301 are vertically arranged on the side wall of the positioning seat 3. The side wall of the positioning seat 3 can be elastically deformed to elastically clamp and position the milling cutter shank of different sizes.

[0024] The positioning seat 3 is used for clamping and positioning the milling cutter. In the embodiment, the edge of the top end of the positioning seat 3 is provided with a guide portion 302 that gradually inclines away from the side of the center of the positioning seat 3 from bottom to top, facilitating the plug-in fixing of the milling cutter shank.

[0025] The bottom end of the first rotating shaft 4 extends below the positioning seat 3 and is fixed with a gear 6. The top end of the outer side wall of the base 1 is provided with a gear ring 5 that is engaged with the gear 6. The top end of the rotating disc 2 is slidably arranged with a top plate 8 through a plurality of support rods 7. The top end of the rotating disc 2 is provided with a linear drive 9 that drives the top plate 8 to slide up and down along the length direction of the support rod 7. In the embodiment, the linear drive 9 is specifically a screw rod that is vertically rotatably arranged at the center of the base 1 and a knob that is fixed at the top end of the screw rod. The screw rod can drive the top plate 8 to move up and down.
