[0030] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0031] See also Figures 1 to 3 As shown, the universal clamp of the present invention includes a fixed plate 1, a first support member 2 rotatably arranged on the fixed plate 1, and a first driving mechanism 3 arranged on the fixed plate 1 and used to drive the first support member 2 to rotate relative to the fixed plate 1. The fixed plate 1 is made of metal material and is roughly a circular flat plate. The first driving mechanism 3 includes a motor and a reducer. The motor drives the first support member 2 to rotate relative to the fixed plate 1 via the reducer.

[0032] It also includes a second support member 4, a clamp assembly 5, and a second drive mechanism 6. The clamp assembly 5 is used to clamp an external workpiece, and an external robot cutting mechanism is used to cut the workpiece clamped by the clamp assembly 5; the clamp assembly 5 has two first shafts 7, and the two first shafts 7 are arranged in a colinear manner. The two first shafts 7 are respectively located on the left and right sides of the clamp assembly 5 away from each other. The two first shafts 7 are respectively rotatably arranged on the first support member 2 and the second support member 4, and the second drive mechanism 6 is arranged on the first support member 2.

[0033] The second drive mechanism 6 is used to rotate the clamp assembly 5. The rotation axis of the first support member 2 intersects the rotation axis of the clamp assembly 5. In this embodiment, the rotation axis of the first support member 2 is arranged vertically, while the rotation axis of the clamp assembly 5 is arranged horizontally. The lower end of the second support member 4 is provided with a roller 8 that is configured to abut against the upper end surface of the fixed plate 1 and rotate. When the first drive mechanism 3 drives the first support member 2 to rotate, the first support member 2, along with the clamp assembly 5 and the second support member 4, rotates, causing the second support member 4 to rotate about the rotation axis of the first support member 2. The roller 8 converts the sliding friction between the second support member 4 and the fixed plate 1 into rolling friction.

[0034] When it is necessary to cut the workpiece, the clamp assembly 5 is used to clamp the external workpiece, the first driving mechanism 3 drives the first support member 2 to rotate together with the clamp assembly 5, and the rotating clamp assembly 5 rotates together with the workpiece to the predetermined position of the fixed plate 1, and the second driving mechanism 6 drives the clamp assembly 5 to rotate together with the workpiece to the robot cutting mechanism. The robot cutting mechanism automatically cuts the workpiece clamped by the clamp assembly 5, and can adjust the workpiece to any angle, thereby improving the cutting efficiency and cutting yield of the workpiece.

[0035] The clamp assembly 5 includes a main body 9 and a clamp part 11 connected to the main body 9. The clamp part 11 is used to clamp an external workpiece. The two first shafts 7 are respectively arranged on two sides of the main body 9 away from each other. In this embodiment, the two first shafts 7 are respectively located on the left and right sides of the main body 9. The main body 9 is rotated on the first support member 2 and the second support member 4 via the two first shafts 7.

[0036] In this embodiment, the clamp member 11 is rotatably mounted on the body 9. The body 9 is provided with a third drive mechanism 12 for driving the clamp member 11 to rotate. The rotation axis of the clamp member 11 is intersecting with the rotation axis of the body 9. Preferably, the rotation axis of the clamp member 11 is perpendicular to the rotation axis of the body 9. In actual use, the third drive mechanism 12 drives the clamp member 11 to rotate, and the rotating clamp member 11 rotates together with the clamped workpiece, thereby achieving fine-tuning of the workpiece position angle, thereby achieving adjustment of the workpiece at any angle, and improving the convenience of adjusting the position of the workpiece relative to the robot cutting mechanism.

[0037] The clamp 11 slides with the body 9, and the body 9 is provided with a fourth drive mechanism 13 for driving the clamp 11 relative to the body 9. During use, the fourth drive mechanism 13 drives the clamp 11 and the workpiece it holds to move, thereby changing the positional relationship between the workpiece held by the clamp 11 and the robot's cutting mechanism, further helping to improve workpiece cutting efficiency and cutting yield.

[0038] The fixture 11 comprises a carrier plate 14, a first clamping plate 15 mounted on the carrier plate 14, a fifth drive mechanism 16, and a second clamping plate 17 movably mounted on the carrier plate 14. The second clamping plate 17 is connected to the output end of the fifth drive mechanism 16. The fifth drive mechanism 16 is used to drive the second clamping plate 17 toward or away from the first clamping plate 15. The first and second clamping plates 15, 17 are used to clamp an external workpiece. During use, an external workpiece is placed between the first and second clamping plates 15, 17. The fifth drive mechanism 16 then drives the second clamping plate 17 toward the first clamping plate 15 until the first and second clamping plates 15, 17 clamp the workpiece.

[0039] A second shaft 18 is rotatably provided on the first support member 2, and the output end of the second driving mechanism 6 is connected to one end of the second shaft 18. The second driving mechanism 6 is used to drive the second shaft 18 to rotate, and the other end of the second shaft 18 is connected to the first disk 19. A first shaft 7 of the clamp assembly 5 is connected to the second disk 21, and the second disk 21 is detachably connected to the first disk 19. The other first shaft 7 of the clamp assembly 5 is rotatably provided on the second support member 4.

[0040] When in use, the second driving mechanism 6 drives the second shaft 18 to rotate, and the rotating second shaft 18 rotates together with the main body 9 via a first shaft 7. The rotating main body 9 rotates together with the clamp 11 and the workpiece clamped by the clamp 11, thereby realizing the rotation of the workpiece and changing the position of the workpiece clamped by the clamp 11 relative to the robot cutting mechanism.

[0041] The second support member 4 has a first frame 22 and a second frame 23 that slides with the first frame 22. A first axis 7 of the clamp assembly 5 is rotatably set on the second frame 23, and a roller 8 is rotatably set on the bottom end of the first frame 22. There are two rollers 8, and the two rollers 8 are respectively located on the front and rear sides of the bottom end of the first frame 22 to ensure that the second support member 4 can rotate stably relative to the fixed plate 1.

[0042] The first frame 22 is provided with a sliding hole (not numbered in the figure) arranged in a vertical direction. The second frame 23 is slidably accommodated in the sliding hole. A threaded positioning member 24 is screwed onto the first frame 22 and protrudes into the sliding hole. The threaded positioning member 24 is used to position the second frame 23 on the first frame 22. During the installation process of the second support member 4, the threaded positioning member 24 is loosened according to the distance between the first shaft 7 and the fixing plate 1, so that the second frame 23 extends or retracts on the first frame 22, thereby changing the height of the second support member 4, thereby allowing the clamp assembly 5 to be accurately rotated and installed with the second support member 4 via the first shaft 7.

[0043] The free end of a first shaft 7 of the clamp assembly 5 is detachably connected to a stop plate 25, which is roughly a circular flat plate. The stop plate 25 is used to stop and abut the side of the second frame 23 away from the main body 9, thereby preventing the first shaft 7 and the second frame 23 from detaching from each other, ensuring that the clamp assembly 5 and the second support member 4 are stably assembled together.

[0044] See also Figures 1 to 4 As shown, in order to achieve the above-mentioned purpose, the cutting device with a universal clamp of the present invention includes a universal clamp, a control station 26 and a cutting mechanism 27. There are multiple universal clamps, and multiple universal clamps are arranged around the cutting mechanism 27. In this embodiment, there are four universal clamps, and the four universal clamps are arranged in a rectangular array. The cutting mechanism 27 is located at the center of the four universal clamps. The cutting mechanism 27 and multiple universal clamps are electrically connected to the control station 26 respectively. The control station 26 is used to adjust the actual operating parameters of the universal clamp and the cutting mechanism 27.

[0045] The cutting mechanism 27 includes a robot 28 movably arranged on the installation ground, a plasma cutting head 29 arranged at the end of the robot 28, a drive motor and an alloy cutting blade 31 arranged on the output shaft of the drive motor. The robot 28 drives the plasma cutting head 29 and / or the alloy cutting blade 31 to cut the workpiece clamped by the universal clamp.

[0046] During actual use, the bottom of each universal clamp is fixedly installed on the workbench 32. According to actual needs, the workbench can be a two-axis workbench or a three-axis workbench, etc. Preferably, a safety guardrail 32 is provided between two adjacent workbenches. The safety guardrail 32 between multiple universal clamps surrounds the cutting mechanism 27 to prevent outside workers from accidentally entering the robot cutting system and being accidentally injured.

[0047] During use, the workpiece is clamped and fixed on a universal fixture on a two-axis workbench or a three-axis workbench according to the requirements of the workpiece. The control station 26 then controls the universal fixture to drive the clamped workpiece to move so that the workpiece moves to the desired position. The control station 26 then controls the ion cutting head 29 and / or the alloy cutting blade 31 of the cutting mechanism 27 to cut the workpiece clamped by the universal fixture, thereby achieving automated cutting of the workpiece. While the cutting mechanism 27 is cutting the workpiece clamped by the first universal fixture, the workpiece is loaded onto the second universal fixture. After the workpiece cutting of the first universal fixture is completed, the cutting mechanism 27 moves to the second universal fixture to cut the workpiece, and the first universal fixture automatically unloads the workpiece, and this cycle is repeated.
