8. A method for using a multi-angle grinder according to any one of claims 1 to 7, characterized in that: The following steps are involved: S1: When the device starts working, the aircraft parts are placed in the grooves on the turntable (3), and six aircraft parts can be placed at the same time; S2: Then the motor (13) is pushed, and the motor (13) drives the slider (23) to move through the swing block (29) and the U-shaped block (24), and the slider (23) moves in the slide groove on the horizontal plate (1). The motor (13) drives the grinding rod (20) to move through the transmission rod (14), the first bevel gear (15), the second bevel gear (19), the rotating rod (25), the round tube (27) and the bolt (28), and moves the grinding rod (20) to one of the aircraft parts. The electric telescopic rod (12) can control the height of the turntable (3) through the support plate (11), thereby adapting to the position of the grinding rod (20); S3: Then the motor (13) is started, the motor (13) drives the transmission rod (14) to rotate, the transmission rod (14) drives the first umbrella gear (15) to rotate, the first umbrella gear (15) drives the second umbrella gear (19) to rotate, the second umbrella gear (19) drives the rotating rod (25) to rotate, the rotating rod (25) drives the grinding rod (20) to rotate through the bolt (28) and the round tube (27), and the grinding rod (20) grinds the deep holes, inclined holes, burrs in the holes and steps on the aircraft parts. Grinding, when it is necessary to adjust the grinding angle of the grinding rod (20), the motor (13) is swung, the motor (13) drives the swing block (29) to swing, the motor (13) drives the transmission rod (14) and the first bevel gear (15) to swing, the motor (13) drives the rotating rod (25), the second bevel gear (19), the bolt (28), the round tube (27) and the grinding rod (20) to swing through the support rod (21) and the support ring (26), and the swing block (29) drives the spring (17) to compress or stretch; S4: In S3, when the U-shaped block (24) moves, the U-shaped block (24) drives the adjustment plate (18) to move through the fixed rod (22), and the limit rod (32) and the limit plate (33) limit the movement range of the adjustment plate (18). The adjustment plate (18) drives the N-shaped plate (7) to move the L-shaped rod (8) through the fixed column (30), and the L-shaped rod (8) drives the movable block (31) to move in the movable groove in the blind hole inside the crossbar (4); S5: If the grinding rod (20) has been ground for the current aircraft part and the next aircraft part needs to be ground, the turntable (3) can be rotated to adjust the position of the aircraft part, and the motor (13) can be rotated to adjust the position of the grinding rod (20). If the position of the aircraft part is adjusted, the turntable (3) is rotated first, and the turntable (3) drives the baffle (9) to rotate. The baffle (9) drives the L-shaped elastic plate (10) to swing. The L-shaped elastic plate (10) can control the position of the aircraft part on the turntable (3) through the baffle (9), thereby rotating the next aircraft part to the position of the grinding rod (20). If the position of the grinding rod (20) is adjusted, the crossbar (4) is rotated first, and the crossbar (4) The N-shaped plate (7) is driven to rotate by the L-shaped rod (8), the N-shaped plate (7) drives the adjustment plate (18) to rotate through the fixed column (30), the adjustment plate (18) drives the U-shaped block (24) to rotate through the fixed rod (22), the U-shaped block (24) drives the slider (23) to rotate, the slider (23) moves to the semicircular groove inside the semicircular plate (2) to rotate, the U-shaped block (24) drives the motor (13) to rotate through the swing block (29), the motor (13) drives the rotating rod (25) to rotate through the support rod (21) and the support ring (26), and the rotating rod (25) drives the grinding rod (20) to rotate, thereby rotating the grinding rod (20) to the next aircraft part that needs to be ground; S6: When the grinding rod (20) grinds the aircraft parts, the vacuum cleaner (6) is started, and the vacuum cleaner (6) absorbs the dust generated during the grinding. The grinding rod (20) is detachable. By rotating the bolt (28), the bolt (28) is taken out from the inside of the round tube (27) and the rotating rod (25), and the grinding rod (20) and the round tube (27) can be disassembled from the rotating rod (25). The grinding rod (20) can be replaced or repaired. The rotating rod (25) can also be installed with various different processing tools in conjunction with the bolt (28), thereby improving the applicability of the device.
