A yag welding machine component that improves output energy stability in peak state

Abstract

The invention provides a YAG welding machine assembly which improves the stability of output energy in the peak state, which includes a rod tube sleeve, a fixed shaft penetrating through the movable block is fixedly connected to the inner wall of the heat conduction shell, and a penetrating to limit shaft is fixedly connected to the left end of the sliding seat. The strike plate on the left side of the ring, the right side of the sliding seat is fixedly connected with the wedge plate corresponding to the left telescopic balloon, the left end of the inner tube is fixedly connected with the push plate corresponding to the telescopic balloon on the left side of the support, and the support Elastic blocks corresponding to the tapered rings are movably plugged into the inner bottom wall of the inner bottom wall. When the YAG welding machine is about to reach the peak value, the internal temperature of the rod sleeve rises, and the vaporized volume of the detection liquid becomes larger, and the movable block is pushed to the right and collides with the impact plate, and the wedge plate squeezes the telescopic balloon to move upward, and the push plate squeezes the inserted The rod moves to the right, and the plunger drives the switch valve to rotate and open through the connecting rod, and the cooling liquid is passed into the cooling branch pipe to perform cooling in advance, which solves the problem that the temperature in the rod sleeve rises suddenly in the peak state, which leads to the damage of the YAG rod and affects the The problem of output energy stability.

Problems solved by technology

[0003] The YAG laser welding machine outputs laser light through the laser. The YAG laser is composed of a working substance (YAG rod), a pump lamp, an optical resonator and a cooling system. To ensure the welding quality and welding stability of the laser welding machine, it is necessary to control the laser. The stability of output energy, the factors that affect the stability of energy output of YAG welding machine include input energy, state of YAG rod and pump light source, etc. Among them, the damage of YAG rod will affect the stability of output energy. In the process of reaching the peak state , the temperature of the impurity inside the YAG rod suddenly rises to thousands of degrees, causing the volume expansion, melting and vaporization of the impurity itself, and then generating a large local stress around the impurity. Once these local stresses exceed the damage limit, they can cause YAG The destruction of the rod, which in turn negatively affects the stability of the output energy
