Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Please refer to fig. 1, an aviation part milling fixture comprises a fixture table 1, two sets of mounting bases 2 are symmetrically mounted on the top surface of the fixture table 1, clamping cylinders 3 are fixedly mounted on the mounting bases 2, sliders 4 are fixedly mounted on telescopic ends of the clamping cylinders 3, turning motors 5 are fixedly mounted on the tops of the sliders 4, clamp plates 6 are fixedly mounted on motor shafts of the turning motors 5, rotating motors 7 are fixedly mounted on the tops of the fixture table 1, the rotating motors 7 are located at the middle positions of the two sets of mounting bases 2, rotating plates 8 are mounted on the tops of the rotating motors 7 through transmission connection of the motor shafts, hydraulic lifting columns 9 are fixedly mounted on the tops of the rotating plates 8, and support clamp plates 10 are fixedly mounted on the tops of the hydraulic lifting columns 9.

The top surface of mount pad 2 is provided with the spout, and the lower extreme slip joint of slider 4 is in the spout, and the accessible spout is spacing to slider 4, prevents the skew of slider 4.

The inner side surface of the clamping plate 6 and the top surface of the supporting clamping plate 10 are both provided with anti-slip lines, so that the friction force of the clamping plate can be improved, and the clamping is more stable.

The top surface fixed mounting of anchor clamps platform 1 has bracing piece 11, and the top of bracing piece 11 supports in the bottom surface of rotor plate 8, can carry out spacing support to rotor plate 8, makes rotor plate 8 operation more stable.

The top of the supporting rod 11 is movably clamped with a ball 12 through a ball groove, the ball 12 is positioned between the supporting rod 11 and the rotating plate 8, the friction force between the supporting rod 11 and the rotating plate 8 is reduced, and the supporting plate 8 is convenient to rotate.

Specifically, when the device is used, the aviation part is placed on the supporting clamping plate 10 in a righting mode, then the two groups of clamping cylinders 3 are started simultaneously, the clamping cylinders 3 drive the sliding block 4, the overturning motor 5 and the clamping plates 6 to integrally move forwards until the two clamping plates 6 respectively clamp the two sides of the aviation part, and then the part can be milled; when the machined surface needs to be turned over and switched, firstly, the hydraulic lifting column 9 contracts to drive the supporting clamping plate 10 to descend, so that the supporting clamping plate does not support and limit the bottom of the part any more, then the two turning motors 5 are started simultaneously to drive the two clamping plates 6 and the whole part to be turned over and changed in surface, then the hydraulic lifting column 9 drives the supporting clamping plate 10 to reset, the bottom surface of the part is supported and fixed again, and then the part can be milled again; when the part needs to rotate to adjust the angle of the milling direction, the clamping cylinder 3 contracts to enable the two clamping plates 6 to be no longer clamped and limited to the part, then the rotating motor 7 is started to drive the rotating plate 8, the hydraulic lifting column 9, the supporting clamping plates 10 and the part to integrally adjust the rotating angle, finally the clamping cylinder 3 drives the two clamping plates 6 to reset to clamp the part again, and then the part can be milled again.
