[0026] The lower surfaces of the two connecting plates 7 are both provided with shielding components 10 for shielding debris generated when the drill bit 9 drills holes.

[0027] The shielding assembly 10 includes a positioning frame 1001, which is fixedly installed in the middle of the lower surface of the corresponding connecting plate 7. Two movable plates 1002 are arranged between the two sides of the inner wall of the positioning frame 1001. Sliding frames 1003 are commonly arranged on both sides of the two movable plates 1002. Semi-open sleeves 1004 are fixedly installed on the opposite sides of the two sliding frames 1003.

[0028] The staff places the workpiece in the fixture 4 set on the upper surface of the turntable 3, and then controls the fixture 4 to clamp the workpiece. Then the staff controls the electric turntable 2 to rotate, and then controls the cylinder 6 and the multi-axis motor 8 to make the drill bit 9 drill the workpiece in the fixture 4. After the fixture 4 rotates to the bottom of the corresponding drill bit 9, the staff controls the cylinder 6 so that its output end drives the positioning frame 1001 and the drill bit 9 to descend, so that the protective sleeve formed by the adjacent semi-open sleeves 1004 can cover the fixture 4 and the drill bit 9, so that when the drill bit 9 rotates at high speed, the flying debris is blocked by the inner wall of the protective sleeve to prevent it from splashing onto the operator's eyes, skin or other body parts, thereby preventing the high-speed moving debris from causing serious harm to the staff.

[0029] In another embodiment of the utility model, a bidirectional screw rod 11 is rotatably installed between the two sides of the inner wall of each positioning frame 1001, and the adjacent movable plates 1002 are respectively threadedly arranged on the two sides of the corresponding bidirectional screw rod 11;

[0030] A motor 12 is fixedly mounted on one side of each positioning frame 1001 away from the turntable 3 , and one end of each bidirectional lead screw 11 passes through the corresponding positioning frame 1001 and is fixedly connected to the output shaft end of the motor 12 .

[0032] The staff starts the motor 12 to make its output shaft end drive the bidirectional screw 11 to rotate. The rotating bidirectional screw 11 drives the movable plate 1002 to move relative to each other by screwing in the thread. When the staff needs to maintain the multi-axis motor 8 or the drill bit 9, they can quickly control the opening and closing of the adjacent semi-open sleeves 1004, thereby increasing practicality.

[0039] During use, the staff places the workpiece in the fixture 4 set on the upper surface of the turntable 3, and then the staff controls the fixture 4 to clamp the workpiece. Then the staff controls the electric turntable 2 to rotate, and then controls the cylinder 6 and the multi-axis motor 8 to make the drill bit 9 drill the workpiece in the fixture 4. After the fixture 4 rotates to the bottom of the corresponding drill bit 9, the staff controls the cylinder 6 so that its output end drives the positioning frame 1001 and the drill bit 9 to descend, so that the protective sleeve formed by the adjacent semi-open sleeves 1004 can cover the fixture 4 and the drill bit 9, so that during the high-speed rotation of the drill bit 9, the flying debris is blocked by the inner wall of the protective sleeve to prevent it from splashing onto the operator's eyes, skin or other body parts, thereby preventing the high-speed moving debris from causing serious harm to the staff.
