In the first embodiment of the present invention, the first,

as shown in the figures 1-2, the utility model comprises a function base 1, two sides of the top end of the function base 1 are respectively provided with a clamping seat 2, two sides of the clamping seats 2 which are close to each other are provided with a hydraulic clamping rod 3, one end of the hydraulic clamping rod 3 which is far away from the clamping seat 2 is provided with a clamping matching mechanism 4, the clamping matching mechanism 4 comprises a function board 5, a connecting sleeve 6 is arranged between the function board 5 and the hydraulic clamping rod 3, one side of the function board 5 which is far away from the hydraulic clamping rod 3 is provided with a clamping board 7, a plurality of adjusting rods 8 are arranged between the clamping board 7 and the function board 5, the adjusting rods 8 are positioned at four corners of the clamping board 7 and the function board 5 and penetrate through the function board 5, a buffer frame 9 which is matched with the hydraulic clamping rod 3 is arranged between the clamping board 7 and the function board 5, buffer frame 9 is character cut in bas-relief shape structure, the inside of buffer frame 9 is equipped with buffer board 10, pinch-off blades 7 is close to one side of function board 5 is equipped with a plurality of evenly distributed's function cooperation piece 11, just function cooperation piece 11 is the triangle-shaped structure, buffer board 10 is close to one side of pinch-off blades 7 is equipped with a plurality of buffer blocks 12, buffer block 12 be with the triangle-shaped structure of 11 the same inclination of function cooperation piece, just buffer block 12 with the inclined plane position orientation of function cooperation piece 11 is opposite.

In the second embodiment, the first embodiment of the method,

on the basis of the first embodiment, as shown in fig. 3-4, the buffer board 10 and one side of the function board 5 that is close to each other are all connected with a circular strip 13 through screws, the circular strip 13 that is located the buffer board 10 side with be located the circular strip 13 of function board 5 side is staggered, the material of circular strip 13 is 65Mn, the both sides on buffer board 10 top all are equipped with the transit plate 14, the transit plate 14 is kept away from one side of buffer board 10 be equipped with a plurality of with buffer frame 9 matched with control threaded rod 15, control threaded rod 15 with be threaded connection between the buffer frame 9, auxiliary groove 16 has all been seted up to the both sides of buffer frame 9, the width of buffer board 10 with auxiliary groove 16's width is the same.

The working principle is as follows: after the equipment is installed and connected, a workpiece is placed between every two clamping matching mechanisms 4, then the equipment is started, the function base 1 and the clamping base 2 control the hydraulic clamping rod 3 to start to operate, the clamping matching mechanisms 4 are driven by the hydraulic clamping rod 3 and approach each other, the workpiece is clamped and fixed in advance along with the fact that the clamping plate 7 in the clamping matching mechanisms 4 contacts the workpiece firstly, the equipment continues to operate, the hydraulic clamping rod 3 continuously approaches and gradually increases clamping force, the clamping plate 7 gradually approaches to the function plate 5 under the limitation of the adjusting rod 8 while continuously maintaining the clamping force, the function matching block 11 and the buffer block 12 gradually approach each other, and the inclined planes face in opposite directions and can contact with each other, the buffer block 10 is pushed to move to one side due to the fact that the buffer block 12 continuously moves downwards to buffer the function matching block 11, so that the clamping force is buffered, meanwhile, under the condition that the circular strips 13 are distributed in a staggered manner, when the buffer plate 10 moves, the circular strips 13 are close to each other to provide resistance to offset the impact force of clamping, the buffer plate 10 is promoted to descend by controlling the matching of the threaded rod 15 and the transfer plate 14 to control the friction force between the circular strips 13, because the circular strips are circular arc-shaped, under the condition that the force is enough, the circular strips 13 can utilize the elasticity of materials to realize staggering and position change, can not be completely fixed and blocked and are difficult to exceed each other, and the structural displacement degree can be effectively controlled by arranging more or less circular strips 13 in a staggered manner and controlling the falling distance of the buffer plate 10, the buffering stroke distance can be changed through the meshing degree between every two circular strips 13, and when the circular strips 13 are not available, the buffer plate 10 is directly contacted with the bottom surface of the buffer frame 9, after buffer board 10 produced the displacement change by buffer block 12, can reach the biggest buffer stroke, and during through the circular strip 13 of the unequal interval of installation inequality, alright push down the distance that buffer block 12 drove buffer board 10 displacement with control function cooperation piece 11 to reduce buffer stroke, directly press from both sides tight fixed, can adapt to the tight operation of clamp of the different forms of different work pieces.
