Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding frame technology, specifically a low-stress welding frame for Invar alloy optical devices. Background Technology
[0002] Invar alloy, also known as Invar, is a nickel-iron alloy known for its extremely low coefficient of thermal expansion (CTE) at room temperature (approximately ±50°C). This characteristic makes it important for applications in optical devices, especially in scenarios requiring high dimensional stability.
[0003] In optical devices and precision instruments, low-stress welded frames are support structures designed with special welding processes and materials (such as Invar alloy). Their core objective is to minimize residual stress caused by welding heat input, thereby maintaining the dimensional stability and alignment accuracy of components under temperature changes or mechanical loads. In high-energy laser systems, Invar alloy lens mounts are mechanical structures used for the precision fixing and support of optical lenses. Their core function is to maintain the optical alignment (such as optical axis position and focal length) and surface accuracy of the lenses when laser power fluctuates or ambient temperature changes, avoiding thermal deformation that could lead to a decrease in laser beam quality or system failure.
[0004] Existing welding frames, when fixing the objects to be welded, cannot be adjusted to adapt to the laser welding process because the welding frame is fixed. This requires stopping the laser for adjustment, which reduces the welding efficiency. To address this, we designed a low-stress welding frame for Invar alloy optical devices to increase the welding efficiency of lasers on objects. Utility Model Content
