Problems solved by technology

[0002] The four-jaw chuck commonly used in the market for laser pipe cutting machines, including the connecting rod cylinder structure, is time-consuming and expensive to process, and has the following disadvantages: 1. The stroke size of the current chuck is mainly due to the direct push structure of the cylinder. The clamping range is 5-360mm, the claw stroke is small, and the opening in the middle of the traditional turntable is limited by the size of the cylinder, so it is difficult to open a large hole; 2. If you encounter a workpiece above 360mm, you need a larger stroke, which leads to The installation space in the diameter direction must also be large, so that the size and weight of the required chuck must be increased, making the overall size large and heavy
3. Complex structure, difficult installation and disassembly, high maintenance cost

Embodiment 1

[0026] like Figure 1-6 , a four-jaw chuck for a laser pipe cutting machine in this embodiment includes a fixed seat 1, on which a turntable 2 is rotated, and the front side of the turntable 2 is respectively provided with horizontal and vertical clamping devices 3, 4, the horizontal and vertical clamping devices 3, 4 each include four runners 5 arranged at four corners, wherein any three pairs of adjacent runners 5 are driven by ring-shaped flexible members 6 Cooperate, wherein, the two flexible pieces 6 that are oppositely arranged are the first and second driven flexible pieces 7, 7-1 respectively, and the remaining flexible piece 6 is the active flexible piece 8, and the first driven flexible piece 6 is the active flexible piece 8. between the outer side of the flexible piece 7 and the inner side of the second driven flexible piece 7-1, and between the inner side of the first driven flexible piece 7 and the second driven flexible piece 7-1 The pressure roller assembly 9 i...

Embodiment 2

[0034] A working method of the four-jaw chuck described in Embodiment 1, comprising the following steps:

[0035] The driving device 10 drives the active flexible member 8 to move, and simultaneously drives the first and second driven flexible members 7 and 7-1 to move synchronously. The outer side and the inner side of the second driven flexible member 7-1 move in the same direction, and the inner side of the first driven flexible member 7 and the second driven flexible member 7-1 move in the same direction. The outer sides move in the same direction. Therefore, a pair of pressure roller assemblies 9 move in the opposite direction. When a pair of pressure roller assemblies 9 move in a straight line toward each other, the pipe material can be clamped, otherwise, the pipe material can be loosened. , a pair of pressing roller assemblies 9 of the lateral clamping device 3 is used for laterally clamping or loosening the pipe material, and a pair of pressing roller assemblies 9 of ...
