Gun barrel seat for laser processing equipment

Abstract

The invention relates to the technical field of laser processing, and discloses a gun barrel seat for laser processing equipment, the gun barrel seat is provided with a first passage and a gas inlet passage, the first passage is axially arranged in a penetrating manner, the gas inlet passage is communicated with the first passage, protective gas enters the first passage through the gas inlet passage, and under the action of the gas inlet passage, the protective gas enters the gun barrel seat. And a spiral air flow is generated in the first passage. Because the protective gas flows in the first passage in a spiral form, the flow resistance caused by the inner wall in the first passage is small, so that the airflow can obtain a relatively consistent flow speed no matter at the edge or the center of the first passage, and the airflow is ensured to integrally flow forwards at a constant speed; therefore, the resistance of particles such as smoke dust and splash to move towards the optical lens along the first passage is increased, the particles such as smoke dust and splash are effectively prevented from being in contact with the optical lens, and the purpose of preventing the optical lens from being polluted and burnt out is achieved.

Description

【Technical field】 [0001] The embodiments of the present invention relate to the technical field of laser processing, and in particular to a barrel seat for laser processing equipment. 【Background technique】 [0002] Laser welding is a new type of welding method in which the focused high-energy laser beam is used as a heating source. It is characterized by small heat input, low welding deformation, high weld strength, non-contact operation, rich welding types, and easy automation and intelligent processing. , high welding speed, high welding precision, large welding depth-to-width ratio and many other advantages, it has been widely used in manufacturing fields such as automobiles, construction machinery, aircraft, home appliances, high-speed rail, ships, and 3C electronics. A complete laser welding equipment or platform generally includes a laser source, laser transmission device, laser welding head, motion control system, welding machine tool, etc., relying on the machine to...

Problems solved by technology

[0005] The usual integrated laser output head and welding head equipment needs to be cooled by cooling water, which has the risk of water leakage, which also leads to large volume, weight and high cost of the integrated laser output head and welding head equipment, and produces The smoke and dust easily pollute the protective lens inside the integrated laser output head and welding head equipment, resulting in damage to the integrated laser output head and welding head equipment
