[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment: As Figures 1-5As shown in the figure, the present utility model provides a robot clamping tooling, which includes a connecting plate 1 and a robot body 2. The outer side of the robot body 2 is fixedly connected to the outer side of the connecting plate 1. A clamping assembly 3 is arranged on the side of the connecting plate 1 away from the robot body 2. The clamping assemblies 3 are symmetrically distributed. The clamping assembly 3 includes a first concave plate 8. A worm 31 is rotatably arranged inside the first concave plate 8. Symmetrically distributed worm wheels 32 are meshed on the outer side of the worm 31. Symmetrically distributed first fixing columns 33 are fixedly arranged inside the first concave plate 8. First connecting rods 34 are fixedly arranged on both sides of the worm wheel 32. One end of the first fixing column 33 rotatably penetrates through the outer sides of the worm wheel 32 and the first connecting rod 34. A second fixing column 35 is rotatably inserted on the outer sides of the two first connecting rods 34. Second concave plates 38 are fixedly arranged at both ends of the second fixing column 35. Clamping blocks 39 are fixedly arranged on the outer sides of the two second concave plates 38. First grooves 392 distributed in a rectangular array are formed inside the clamping blocks 39. Springs 393 are fixedly arranged inside the first grooves 392. A clamping column 391 is fixedly arranged at one end of the spring 393. The outer side of the clamping column 391 is movably connected to the inside of the first groove 392. By arranging the clamping assembly 3, when the worm 31 rotates, it drives the two worm wheels 32 to rotate in opposite directions. When the worm wheels 32 rotate, they drive the two first connecting rods 34 to move in opposite directions. The movement of the first connecting rod 34 drives the second concave plate 38 to move towards each other through the second fixing column 35. When the clamping column 391 contacts the workpiece, under the elastic action of the spring 393, the clamping column 391 will contract, and clamping of workpieces with different sizes and specifications can be realized. Symmetrically distributed third fixing columns 36 are fixedly arranged inside the first concave plate 8. Symmetrically distributed second connecting rods 37 are rotatably arranged on the outer sides of the third fixing columns 36. By arranging the third fixing columns 36 and the second connecting rods 37, it is convenient to cooperate with the connecting column 30 subsequently, so that the second concave plate 38 will not shake during movement. Connecting columns 30 are fixedly arranged inside the two second concave plates 38. The outer sides of the connecting columns 30 are rotatably connected to the outer sides of two of the second connecting rods 37. By arranging the connecting columns 30 and using them in cooperation with the third fixing columns 36 and the second connecting rods 37, the second concave plate 38 will not shift during movement, and the second concave plate 38 can move towards each other.

[0019] A through hole 22 is formed inside the connecting plate 1. A bidirectional threaded rod 62 is arranged inside the through hole 22. Symmetrically distributed moving blocks 6 are sleeved on the outer side of the bidirectional threaded rod 62. A rotating column 4 is rotatably installed on the outer side of the moving block 6. A slider 5 is rotatably sleeved on the outer side of the rotating column 4. By providing the bidirectional threaded rod 62, the moving block 6, the rotating column 4 and the slider 5, the rotation of the bidirectional threaded rod 62 drives the moving block 6, the rotating column 4 and the slider 5 to move towards each other. The movement of the slider 5 drives the first concave plate 8 to move towards each other. The movement of the first concave plate 8 towards each other drives the clamping assembly 3 to move towards each other. The distance between the two clamping assemblies 3 can be adjusted so that the robot clamping tooling can clamp the workpiece more firmly. Symmetrically distributed sliding grooves 21 are formed inside the connecting plate 1. Both ends of the two sliders 5 are slidably clamped inside the sliding grooves 21. By providing the sliding grooves 21, the slider 5 can drive the clamping assembly 3 to move towards each other, realizing the adjustment of the distance between the two clamping assemblies 3. A second groove 601 is formed inside the moving block 6. A first motor 7 is fixedly arranged inside the second groove 601. The output shaft of the first motor 7 is fixedly connected to one end of the rotating column 4. By providing the first motor 7, the rotation of the rotating column 4 is driven, so that the subsequent clamping column 391 can clamp the workpiece. A second motor 61 is fixedly arranged inside the through hole 22. The output shaft of the second motor 61 is fixedly connected to one end of the bidirectional threaded rod 62. By providing the second motor 61, the rotation of the bidirectional threaded rod 62 is driven, so that the subsequent two clamping assemblies 3 can move towards each other. One end of the rotating column 4 close to the second concave plate 38 rotatably penetrates through the first concave plate 8 and is fixedly connected to one end of a worm 31. The side of the slider 5 away from the first motor 7 is fixedly connected to the outer side of the first concave plate 8. By fixedly connecting the rotating column 4 and the worm 31, the rotation of the rotating column 4 can drive the worm 31 to rotate together. The slider 5 is fixedly connected to the first concave plate 8, so that the slider 5 will drive the first concave plate 8 to move together when moving.

[0020] Working principle: First, start the second motor 61. The output shaft of the second motor 61 drives the bidirectional threaded rod 62 to rotate. The rotation of the bidirectional threaded rod 62 drives the two moving blocks 6 to move towards each other. The movement of the moving blocks 6 drives the first motor 7 and the rotating column 4 to move together. The movement of the rotating column 4 drives the slider 5 and the clamping assembly 3 to move together. When adjusted to the appropriate position, turn off the second motor 61. By adjusting the distance between the two clamping assemblies 3, the robot clamping tooling can clamp the workpiece more firmly, improving production efficiency. Then start the first motor 7. The output shaft of the first motor 7 drives the rotating column 4 to rotate. The rotation of the rotating column 4 drives the worm 31 to rotate. The rotation of the worm 31 drives the two worm wheels 32 to rotate in the opposite direction. The rotation of the worm wheels 32 drives the first connecting rod 34 to move in the opposite direction. The movement of the first connecting rod 34 drives the second concave plate 38 to move towards each other through the second fixed column 35. The opposite movement of the second concave plate 38 drives the clamping block 39 and the clamping column 391 to move towards each other. The clamping column 391 will contract under the elastic action of the spring 393, enabling clamping of workpieces of different sizes and specifications, and improving the application range of the robot clamping tooling.
