The working principle of the scheme has the beneficial effects that: the composite material product to be turned is mounted on the flange plate 12, then when the oil cylinder 3 pushes the swing connecting rod 5 to rotate 90 degrees, the flange plate 12 can rotate 180 degrees under the driving of the limiting ring 8, and because the brake block 13 is fixedly connected to the outer peripheral side of the flange plate 12, when the rotating angle of the flange plate 12 exceeds 180 degrees, the brake block 13 can be abutted to the limiting component 14, at this time, the brake block 13 firstly can give an upward impact force to the elastic rod 26, the force can enable the elastic rod 26 to move upwards along the inner cavity of the connecting sleeve 23, and the elastic ball 24 can mutually press between the groove one 25 and the groove two 27 while sliding, so that the compressive strength is enhanced, the buffering force is slowed down, because the upper end of the elastic rod 26 is in a circular arc shape, and the bottom of the first connecting plate 22 is provided with an arc-shaped groove corresponding to the top of the elastic rod 26, when the impact force exceeds the buffering force of the elastic ball 24, the elastic rod 26 pushes the first connecting plate 22 to slide upwards and abut against the outer wall of the flexible shell 201 (the material of the flexible shell 201 can be rubber or any other energy-absorbing flexible material), at this time, the first hinging rod 28 and the second hinging rod 29 move towards the direction approaching to each other, the included angle between the first hinging rod 28 and the second hinging rod 29 becomes smaller, the flexible shell 201 wrapped around the periphery is ejected towards the inner wall of the first installation cavity 21, part of the impact force can be absorbed by the stress deformation of the flexible shell 201, and a certain gap is reserved between the flexible shell 201 and the inner wall of the first installation cavity 21 in the initial state (the size of the gap is designed according to the range of the rotation angle limited by the required flange 12, assuming that the maximum rotation angle of the flange 12 does not allow more than 185 °, the gap is 1-1.5 cm), the flexible casing 201 will abut against the inner wall of the mounting cavity 21 when the maximum deformation allowed is reached, thus preventing the first hinge lever 28 and the second hinge lever 29 from continuing to approach each other;
at the same time, the first link 31 and the second link 33 are rotated in a direction approaching each other, so that the first link 31 and the second link 33 push the elastic link 45 along the inner wall of the buffer sleeve 46 through the common hinge point, so that the buffer spring 47 in the buffer sleeve 46 is compressed to absorb kinetic potential energy;
meanwhile, as the distance between the second connecting plate 34 and the pressure plate 202 is reduced, the first rubber pad 38 arranged on the connecting arm 37 receives pressure from the pressure plate 202, the second rubber pad 39 arranged on the connecting arm 37 receives pressure from the second connecting plate 34, so that the connecting arm 37 rotates around the third rotating shaft 41 and rotates towards the direction tending to be horizontal, at the moment, the two groups of ruler springs 43 compress and absorb kinetic potential energy and store energy, so that the rotating angle of the flange 12 can be basically limited to be less than 185 degrees, and when the brake block 13 impacts the damping device 20, the impact force is weakened step by step through the arrangement of a multi-stage buffer structure, so that the rotating speed of the flange 12 is slowly slowed down, and the effect of protecting a composite material product is achieved;
after the impact force disappears, the ruler spring 43 releases the accumulated energy and drives the connecting arm 37 to restore to the original state, so that the distance between the second connecting plate 34 and the pressure plate 202 is restored, at this time, the flexible shell 201 also gives a reaction force to the first connecting plate 22, so that the first connecting plate 22 slides downwards along the first mounting cavity 21, and the elastic rod 26 is pushed and restored;
it should be noted that, since the distance between the stop rod 16 and the brake block 13 is greater than the distance between the limiting assembly 14 and the brake block 13, if the brake block 13 continues to rotate (i.e. the rotation angle of the flange 12 exceeds 185 °) after abutting against the limiting assembly 14 and reducing the impact force, the brake block 13 will abut against the stop rod 16 at this time, so that the flange 12 stops rotating, and the distance between the limiting assembly 14 and the brake block 13 can be adjusted by adjusting the connecting bolt 18, so as to achieve the required limiting angle requirement.
The structure not only can play a role in adjusting the rotation angle of the flange 12 at any time, but also can play a role in protecting a composite material product by absorbing impact force through the damping device 20 arranged in the flange 12 when the flange exceeds a limiting angle.
