[0017] The gripper clamping mechanism comprises a connecting pipe rack 4, a splint 5, a beam plate 6 and an L-shaped bottom plate 7, wherein a connecting pipe rack 4 is fixedly installed at the end of the cylinder telescopic shaft of the bidirectional telescopic cylinder 2, and the two pipe ports of the connecting pipe rack 4 are fixed with connecting splints 5, and two adjacent splints 5 are connected and fixed by the beam plate 6, and the beam plate 6 is located at the top of the connecting pipe rack 4, and an L-shaped bottom plate 7 is arranged on the outer side of the bottom of the beam plate 6, and a waist-shaped mounting hole 8 and a plurality of fixing screw holes 9 arranged in parallel with equal intervals from top to bottom are opened on the splint 5, and the L-shaped bottom plate 7 is fixed by bolts of a fixing back plate 10, and an arc-shaped concave surface 11 is arranged at the edge of the bottom plate of the L-shaped bottom plate 7.

[0018] The beam plate 6 and the guide rail 3 are slidably connected via a slider 12 , and a connecting rod 13 is fixedly installed on the top end of the fixed top plate 1 , and an external lifting shaft or mechanical equipment can be connected via the connecting rod 13 .

[0019] The bidirectional telescopic cylinder 2 drives the left and right symmetrical clamping plates 5 to move toward each other through the cylinder telescopic shafts on the left and right sides, and the objects are grasped and clamped through the left and right clamping plates 5.

[0020] The L-shaped bottom plate 7 and the clamping plate 5 are fixedly connected by external bolts at fixing screw holes 9, which are used to adjust the upper and lower heights of the L-shaped bottom plate 7 installed on the side of the clamping plate 5 to adapt to the grasping and clamping of objects of different heights.

[0021] Working principle:

[0022] In this scheme, the whole device is connected to an external lifting rod or mechanical equipment through a connecting rod 13 at the top of the fixed top plate 1. When clamping an object, the two-way telescopic cylinder 2 at the center of the bottom surface of the fixed top plate 1 works, and at the same time controls the movement of the cylinder telescopic shafts on the left and right sides, driving the left and right clamping plates 5 to move outwards relative to each other. The clamping plates 5 are four pieces, so that the clamping plates 5 are respectively located at the outside of the four sides of the object. The two-way telescopic cylinder 2 works again, driving the left and right clamping plates 5 to move closer to each other, and the bottom surface of the L-shaped bottom plate 7 at the bottom of the clamping plate 5 shovels the bottom surface of the clamped object, thereby realizing the grabbing and clamping effect on the object;

[0024] An L-shaped bottom plate 7 is installed on the outer side of the bottom of the clamping plate 5, and an arc-shaped concave surface 11 is arranged at the edge of the bottom plate of the L-shaped bottom plate 7. When the four clamping plates 5 move horizontally to the left and right, they can clamp and hold up a round object.

[0025] The clamping plate 5 and the L-shaped base plate 7 are fixed by waist-shaped mounting holes 8, and the upper and lower maximum range heights of the L-shaped base plate 7 at the clamping plate 5 can be adjusted, and then fixed by external bolts at the fixing back plate 10 and the fixing screw holes 9, so as to facilitate the clamping of objects of different heights.
