[0003] Existing follower support devices have a small clamping range for workpieces. To accommodate workpieces of different sizes, the clamping jaws are fitted with mounting holes of varying spacing on their mounting bases. By mounting the jaws in different holes, the problem of clamping workpieces of different sizes can be solved. However, this method is very inconvenient to use. When machining workpieces of different sizes, the jaws need to be disassembled and reinstalled in the appropriate holes, resulting in low machining efficiency. Furthermore, repeated installation and reinstallation can easily cause jaw position shifts, affecting machining accuracy.

The rocker arm 8 is rotatably connected to the pins 7. The two rocker arms 8 are symmetrically distributed. A guide hole 14 is opened on the rocker arm 8. The guide hole 14 is elongated.

[0032] A lifting plate 17 is provided on the front side of the main frame 1. A screw nut 19 is fixedly connected to the rear side of the lifting plate 17. The screw nut 19 is installed on the lead screw 3. A second guide rail 29 is installed on the front side of the main frame 1. A second slider 30 is fixedly connected to the rear side of the lifting plate 17. The lifting plate 17 is slidably installed on the second guide rail 29 through the second slider 30. A second support seat 25 is fixedly connected to the front side of the lifting plate 17. Two telescopic shafts 28 are fixedly connected to the second support seat 25. A roller frame 26 is installed on the telescopic shaft 28. A second roller 27 is rotatably connected to the roller frame 26. A spring 24 is sleeved on the telescopic shaft 28.

[0033] A cylinder bracket 10 is fixedly installed on the front side of the lifting plate 17. The cylinder bracket 10 is located at the lower part of the second support base 25. The cylinder 4 is fixedly installed on the cylinder bracket 10. The clamping seat 20 is fixedly connected to the front part of the second support base 25. A first guide rail 5 is installed on the clamping seat 20. Two first sliders 6 are slidably installed on the first guide rail 5. The two first sliders 6 are symmetrically distributed. A clamping roller 11 is fixedly installed on the upper part of the first slider 6. A guide shaft 31 is installed on the front part of the first slider 6.

[0034] Working process: When it is necessary to support the workpiece of the laser tube cutting machine:

[0035] The drive motor 15 drives the first synchronous pulley 22. The rotation of the first synchronous pulley 22 drives the synchronous transmission belt 21 to drive the second synchronous pulley 23 to rotate, causing the lead screw 3 to rotate. The lead screw 3 drives the lifting plate 17 to rise along the second guide rail 29, and supports the workpiece through the second roller 27.

[0036] The piston rods of the two cylinders 4 extend outwards to raise the thrust seat 13 from the lowest point to the highest point. The thrust seat 13 drives the two connecting rods 9 to change their angle. During the lifting and lowering process, the thrust seat 13 moves along the guide groove. Through the guide block 18 and the guide groove, the piston rods of the two cylinders 4 are prevented from tilting during the lifting process due to asynchronous speeds.

[0037] When the two connecting rods 9 change their angle, they drive the two rocker arms 8 to rotate along the pin 7. When the rocker arms 8 rotate, they drive the guide shaft 31 to slide in the guide hole 14 and move horizontally, thereby driving the two first sliders 6 to move along the first guide rail 5 and changing the distance between the two clamping rollers 11.

[0038] When the piston rod of cylinder 4 is fully extended: the two rocker arms 8 and the two connecting rods 9 are distributed in a W shape, the distance between the two grippers is at its maximum, and the grippers reach their maximum clamping size;

[0039] When the piston rod of cylinder 4 is fully retracted: the two rocker arms 8 and the two connecting rods 9 are arranged in an isosceles triangle, the distance between the two grippers is the smallest, and the grippers reach the minimum clamping size.

[0040] With two sets of connecting rods 9, this product can achieve a larger clamping range and does not require adjustment of the position of the two clamping rollers 11, eliminating the need for disassembly and installation, and improving processing efficiency and accuracy.

[0041] Before the lifting plate 17 is raised, the piston rods of the two cylinders 4 are in the retracted state, at which time the distance between the two clamping rollers 11 is minimal. When the lifting plate 17 is raised, the piston rods of the two cylinders 4 are fully extended, maximizing the distance between the two clamping rollers 11. After the second horizontal roller 27 lifts the workpiece, the piston rods of the two cylinders 4 begin to retract, causing the two clamping rollers 11 to push the workpiece from both sides to the center position of the second horizontal roller 27. After clamping the workpiece, the piston rods of the cylinders 4 stop retracting. When the clamping rollers 11 clamp the workpiece, since the cylinders 4 cannot continue to drive after contacting the workpiece, the clamping rollers 11 can adapt to workpieces of different sizes.
