Technical Field

[0001] The utility model relates to the technical field of power chucks for laser pipe cutting machines, in particular to a laser power chuck with a heavy-duty cylinder direct-push rotation synchronization mechanism. Background Art

[0002] The power chuck of the laser tube cutting machine refers to the key technology used to clamp the tube in the laser tube cutting machine. In the laser tube cutting machine, the chuck plays an important role in fixing and clamping the tube, which affects the cutting accuracy and stability. With the development of laser tube cutting technology, the chuck technology is also constantly innovating and improving.

[0003] In the prior art, the power chucks of many laser tube cutting machines have limited load-bearing capacity. When processing overweight workpieces, they cannot be effectively fixed, resulting in a limited processing range. Therefore, when processing overweight workpieces, it is often necessary to purchase new load-bearing chucks, which greatly increases the processing cost. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. The power chucks of many laser tube cutting machines have limited load-bearing capacity and cannot be fixed when processing overweight workpieces, resulting in a limited processing range and the need to purchase new chucks, thereby increasing processing costs.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a heavy-load cylinder direct-push rotating synchronous mechanism laser power chuck, including a base, a mounting plate is provided on the base, four groups of fixed frames are provided on the mounting plate, and the first cylinder, the second cylinder, the third cylinder and the fourth cylinder are respectively installed on the four groups of fixed frames, and the output ends of the first cylinder, the second cylinder, the third cylinder and the fourth cylinder are each provided with two piston rods, and a connecting frame is fixed to the end of every two adjacent piston rods, and the connecting frame is rotatably connected to the roller clamp away from the piston rod.

[0006] Optionally, the first cylinder and the third cylinder, and the second cylinder and the fourth cylinder are arranged opposite to each other.

[0007] Optionally, a through hole is respectively provided on both sides of the connecting frame, and linear bearings are installed at one end of the through holes close to each other.

[0008] Optionally, a guide rod is slidably connected inside the linear bearing.

[0009] Optionally, both sides of the connecting frame to which the first cylinder and the third cylinder belong are connected to a rotating connecting rod for opposite rotation, and the four rotating connecting rods are connected to two ends of a middle connecting rod for rotation in pairs.

[0010] Optionally, the two middle connecting rods are arranged on a central fixed shaft, and the central fixed shaft is rotatably connected to a fixed frame.

[0011] Optionally, the positions of the fixing frames of the first cylinder and the third cylinder are higher than the fixing frames of the second cylinder and the fourth cylinder, and the installed structures are staggered with each other.

[0012] Optionally, a shield baffle is embedded in the outer shell of the base on one side close to the roller clamp, and two dustproof plates are installed in the empty space in the center of the shield baffle.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, each pair of cylinders arranged opposite to each other pushes the same piston rod forward at the same time, so that the roller clamps at the front ends of the two connecting frames approach each other to clamp the workpiece. At the same time, four cylinders are arranged, and each cylinder adopts a two-piston rod design, which effectively improves the output limit of the cylinder, so that heavier workpieces can be clamped.

[0015] 2. In the utility model, by setting a rotating connecting rod and a middle connecting rod, a smoother and more synchronous control of the movement of each pair of connecting frames arranged in opposite directions is achieved. In conjunction with the guide rod and the linear bearing, the clamping stability of the roller clamp is effectively improved, thereby preventing the safety hazards caused by the bending or breakage of the clamping component. Such a design can support heavier workpieces and expand the processing range. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a heavy-duty cylinder direct-push rotating synchronous mechanism laser power chuck, comprising a base 1, a mounting plate 4 is provided on the base 1, four sets of fixing frames 5 are provided on the mounting plate 4, a first cylinder 6, a second cylinder 7, a third cylinder 8 and a fourth cylinder 9 are respectively installed on the four sets of fixing frames 5, two piston rods 15 are respectively provided at the output ends of the first cylinder 6, the second cylinder 7, the third cylinder 8 and the fourth cylinder 9, and a connecting frame 10 is fixed at the ends of every two adjacent piston rods 15, the connecting frame 10 is rotatably connected to a roller clamp 11 away from the side of the piston rod 15, and the first cylinder 6 and the third cylinder 8, the second cylinder 7 and the fourth cylinder 9 are respectively arranged opposite to each other.

[0024] In this embodiment, each pair of oppositely arranged cylinders pushes the same piston rod 15 forward at the same time, so that the roller clamps 11 at the front ends of the two connecting frames 10 approach each other to clamp the workpiece. At the same time, four cylinders are set, and each cylinder is designed with two piston rods 15, which effectively improves the output limit of the cylinder, so that heavier workpieces can be clamped.

[0025] A through hole 14 is respectively formed on both sides of the connecting frame 10 , and a linear bearing 13 is installed at one end of the through holes 14 close to each other, and a guide rod 12 is slidably connected inside the linear bearing 13 .

[0026] In this embodiment, the design of the guide rod 12 and the linear bearing 13 enables the connecting frame 10 and the roller clamp 11 to move along the guide rod 12 , thereby fixing the moving direction of the roller clamp 11 .

[0027] Both sides of the connecting frame 10 to which the first cylinder 6 and the third cylinder 8 belong are connected to a rotating connecting rod 16 for opposite rotation. The four rotating connecting rods 16 are connected to the two ends of a middle connecting rod 17 for rotation in pairs. The two middle connecting rods 17 are arranged on a central fixed shaft 18, and the central fixed shaft 18 is rotatably connected to the fixed frame 5.

[0028] In the present embodiment, by providing a rotating connecting rod 16 and a middle connecting rod 17, a smoother and more synchronous control of the movement of each pair of oppositely arranged connecting frames 10 is achieved. In conjunction with the guide rod 12 and the linear bearing 13, the clamping stability of the roller clamp 11 is effectively improved, thereby preventing safety hazards caused by bending or breaking of the clamping assembly. Such a design can support heavier workpieces and expand the processing range. There is no need to purchase new fixtures, thereby reducing processing costs. In addition, it can also prevent the roller clamp 11 from being unbalanced due to the workpiece being too heavy, causing uneven output of the cylinder piston rod 15 and damaging the cylinder.

[0029] The position of the fixing frame 5 of the first cylinder 6 and the third cylinder 8 is higher than the fixing frame 5 of the second cylinder 7 and the fourth cylinder 9, and the installed structures are staggered with each other. A shield baffle 2 is embedded in the outer shell of the base 1 on the side close to the roller clamp 11, and two dustproof plates 3 are installed in the empty space in the center of the shield baffle 2.

[0030] In this embodiment, the mechanical structure of the first cylinder 6 and the third cylinder 8 is higher than the mechanical structure of the second cylinder 7 and the fourth cylinder 9, so that the outputs of the two pairs of cylinders do not interfere with each other. The shield baffle 2 and the dustproof plate 3 play a protective and dustproof role.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
