Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following specific embodiments.

As shown in Figure 1-2, an automatic milling nozzle mechanism includes a base 1 on which a milling cutter fixing seat 2, a sliding seat 3 and a sliding seat driving mechanism 4 are arranged, and the milling cutter fixing seat is provided with There is a vertically downward milling cutter 21 and a high-speed motor 22 that can drive the milling cutter to rotate at high speed; the sliding seat is provided with a product fixing seat 31, a product left-side alignment mechanism and a product right-side alignment mechanism, The product’s left-side alignment mechanism and the product’s right-side alignment mechanism are placed outside the two sides of the product’s fixing seat. The direction of the line where the product’s left-side alignment mechanism and the product’s right-side alignment mechanism are located is the Y direction, and the vertical The direction in the Y direction and parallel to the upper surface of the base is the X direction. The left adjustment mechanism of the product includes a left adjustment cylinder 321, a left slider 322, and several cylinders fixed on the left slider close to the product. The left top block (323) on the side of the fixed seat, the left full position cylinder can drive the left slide block to approach and move away from the product fixed seat along the Y direction; the product right side full position mechanism includes a right full position cylinder 331, The right slider 332 and several right top blocks 333 fixed on the side of the right slider close to the product fixing seat, the right full position cylinder can drive the right slider to approach and move away from the product fixing seat along the Y direction The product fixing seat is provided with a vacuum suction cup; the sliding seat is slidably arranged on the base along the X direction, and the driving mechanism of the sliding seat can drive the sliding seat to move back and forth along the X direction of the base.

During work, the product to be processed is placed on the product fixing seat 31 by the manipulator, and the left and right positioning cylinders 321, 331 of the product left side positioning mechanism and the product right side positioning cylinder are started simultaneously, and the left and right positioning cylinders 321, 331 are activated. 331 respectively drives the left and right sliders 322,332 close to the product fixing seat 31, and the left and right top blocks 323,333 on the left and right sliders 322,332 press the product respectively to position the product on the product fixing seat.
