Description

Technical Field

[0001] This utility model relates to the field of laser tube cutting machine technology, and more specifically, to a servo-driven two-chuck synchronous moving laser tube cutting machine. Background Technology

[0002] The "front clamping assembly movement" method has been used in the laser side-mounted tube cutting industry for many years. However, after the rear clamping assembly moves into place, it needs to wait for the front clamping assembly to move into place before it can continue moving. This waiting period results in wasted time and reduced equipment operating efficiency. To improve this, existing solutions involve installing a cylinder at the bottom of the front clamping assembly. For example, a laser tube cutting machine with authorization announcement number CN 220902209 U has a front clamping assembly that includes a first side slide, a hollow chuck mounted on the first side slide, and a displacement cylinder fixed to the side bracket. The displacement cylinder can drive the first side slide to move laterally. The displacement cylinder has a low manufacturing cost. However, this type of front clamping assembly for laser tube cutting machines has the following drawbacks: First, the bottom cylinder is difficult to install and debug, affecting production progress; second, the cylinder is prone to failure in the later stages of use, resulting in high after-sales maintenance costs; third, when the cylinder is lifted, the rear clamping assembly wastes time, and the front and rear clamping assemblies cannot achieve synchronization, affecting cutting efficiency.
