[0039] like Figure 9-10 It is shown that a UAV mechanical arm mounting device for live operation of the present invention is based on the first embodiment;

The end of the round rod 72 away from the electric hydraulic cylinder 71 is fixedly connected to a connecting plate 73, and the end of the connecting plate 73 away from the round rod 72 is slidably connected to a buffer rod 74, and the end of the buffer rod 74 away from the connecting plate 73 is fixedly connected to a contact mechanism 76, and a third spring 75 is sleeved on the buffer rod 74, one end of the third spring 75 is fixedly connected to the side of the connecting plate 73, and the other end of the third spring 75 is fixedly connected to the contact plate 761; after the mechanical arm 4 is installed on the mounting frame 5, by opening the electric hydraulic cylinder 71, the connecting plate 73 is driven to move toward the mechanical arm 4 through the round rod 72 through the output end of the electric hydraulic rod, and at the same time, the contact mechanism 76 is driven to counteract the mechanical arm 4 through the connecting plate 73 and the buffer rod 74, so as to avoid the mechanical arm 4 from swinging uncontrollably when the UAV encounters air turbulence when the mechanical arm 4 follows the body 1 to fly and move;

[0041] The contact mechanism 76 includes a contact plate 761, and the side surface of the contact plate 761 is fixedly connected to the end of the buffer rod 74 away from the connecting plate 73. The side surface of the contact plate 761 is provided with a mounting groove 762, and the inner side of the mounting groove 762 is rotatably connected with a rubber rod 763; when the connecting plate 73 drives the contact plate 761 to resist the side surface of the mechanical arm 4 through the buffer rod 74, the rubber rod 763 is provided on the inner side of the contact plate 761, so as to avoid the extrusion force between the contact plate 761 and the mechanical arm 4 causing extrusion damage to the mechanical arm 4, and the rubber rod 763 is provided at the same time, so as to increase the friction between the mechanical arm 4 and the mechanical arm 4. At the same time, when the mechanical arm 4 rotates, when the mechanical arm 4 rotates and squeezes the contact plate 761, the contact plate 761 can slide on the connecting plate 73 through the buffer rod 74, and at the same time, through the buffering work of the third spring 75, it is avoided that the extrusion force between the contact plate 761 and the mechanical arm 4 is too large, which will cause the inconvenience of rotating the mechanical arm 4.

[0042] The specific workflow is as follows:

[0044] By installing the connection mechanism 66 and the limiting mechanism 65 in a limited position, the connection mechanism 66 is connected to the inner side of the connection shell 61, so that the mechanical arm 4 is mounted. At the same time, when the body 1 drives the connection shell 61 to move in flight, the connection seat 661 can be driven by the sliding rod 62 to slide in the connection shell 61. At the same time, the first spring 63 works as a buffer. The drone will generate vibrations during flight, so as to avoid these vibrations being transmitted to the mechanical arm 4 to affect its working accuracy.

[0045] By pushing the connection seat 661 upward, the connection column 662 is abutted against the circular hole on the top of the connection shell 61, and the limiting assembly 655 slides in the limiting groove 652, so that the limiting block 6551 is abutted against the connection groove 664, and the inclined groove 6552 on the limiting block 6551 is abutted against the inner protrusion of the connection groove 664, so that the position of the connection seat 661 is limited and fixed. Since the top of the robot arm 4 is fixedly connected to the bottom of the connection seat 661, the connection seat 661 is driven downward by the weight of the robot arm 4, so that the inclined groove 6552 on the limiting block 6551 is locked with the protrusion on the inner side of the connection groove 664, so as to avoid the robot arm 4 from loosening when the robot arm 4 is moved.

[0046] When the robot arm 4 needs to be disassembled, the connecting seat 661 is pushed upward, so that the inclined groove 6552 on the top of the limit block 6551 and the inclined block inside the connecting groove 664 are squeezed and moved upward, so that the limit block 6551 moves in the limit groove 652 through the sliding rod 653, so that the limit block 6551 is separated from the connecting groove 664, and the connecting seat 661 is continuously pushed upward, so that the arc plate 6553 on the limit block 6551 is abutted against the inner side of the giving way groove 665, and the connecting seat 661 is rotated, so that the position of the limit block 6551 and the connecting groove 664 is offset, so that the connecting seat 661 is dragged downward, so that the connecting seat 661 is separated from the limit plate 651;

[0047] After the mechanical arm 4 is mounted on the mounting frame 5, the electric hydraulic cylinder 71 is turned on, and the connecting plate 73 is driven to move toward the mechanical arm 4 through the round rod 72 through the output end of the electric hydraulic rod, and at the same time, the contact mechanism 76 is driven by the connecting plate 73 through the buffer rod 74 to counteract the mechanical arm 4, so as to prevent the mechanical arm 4 from swinging uncontrollably when the UAV encounters air turbulence when the mechanical arm 4 follows the body 1 to fly;

[0048] When the connecting plate 73 drives the contact plate 761 to resist the side of the robot arm 4 through the buffer rod 74, a rubber rod 763 is set on the inner side of the contact plate 761 to avoid the extrusion force between the contact plate 761 and the robot arm 4 causing extrusion damage to the robot arm 4. At the same time, the rubber rod 763 is set to increase the friction between the robot arm 4 and the contact plate 761. At the same time, when the robot arm 4 rotates and is squeezed by the contact plate 761, the contact plate 761 can slide on the connecting plate 73 through the buffer rod 74. At the same time, the buffering work of the third spring 75 is used to avoid the extrusion force between the contact plate 761 and the robot arm 4 being too large, which will cause the inconvenience of rotating the robot arm 4.
