Description

Technical Field

[0002] Galvanometer laser welding is an efficient and precise welding technology that is widely used in many industries, especially in the fields of manufacturing and processing. Laser welding is the process of using the high energy density of the laser beam to heat the metal material to a molten state to form a weld. In some welding processes, shielding gas can prevent oxidation of the welding area and improve the welding quality. However, due to its working principle and structural characteristics, the galvanometer laser welding device is not very convenient to use shielding gas, which may cause oxidation and discoloration on the welding surface, affecting the appearance of the weld.

When the telescopic plate 304 moves downward, the gas inside the plate shell 305 is compressed into the interior of the air pressure pipe 404, and the gas enters the interior of the oil tank 401 along the air pressure pipe 404. The liquid inside the oil tank 401 enters the interior of the oil pipe 402 under the pressure of the gas, and the air pressure valve inside the oil pipe 402 is forced to open, and the liquid flows into the groove of the oil tank 403 along the interior of the oil pipe 402, and lubricates the connecting part of the sliding column 301 and the workbench 1, which plays a protective role, prevents the sliding column 301 from moving too much and causing surface damage, and saves resources.

[0026] Working principle: Place the parts to be welded on the sliding column 301, and then turn on the external motor. The long fixing plate 201 drives the middle fixing plate 202 to move left and right through the built-in driving component. The middle fixing plate 202 drives the small fixing plate 203 to move forward and backward through the built-in driving component. The small fixing plate 203 moves up and down with the mechanical arm 204. When it moves to the specified position, the mechanical arm 204 moves down with the protective air pipe 207 and the transparent protective shell 212. The mechanical arm 204 drives the long slide plate 205 to move down. The long slide plate 205 moves down along the slide groove of the vertical fixing plate 206. When the transparent protective shell 212 drops to the specified position, it starts to squeeze the sliding column 301 and the pressure plate 302. The laser auxiliary plate 211 moves downward with the welding head 208 and touches the surface of the part, and squeezes and fixes the part, flattens the surface of the deformed plate-like part, and helps the welding head 208 to weld better. When the laser auxiliary plate 211 squeezes the part, the elastic spring 210 is forced to shrink inward, and the laser auxiliary plate 211 also shrinks to the inside of the telescopic shell 209. When the welding is completed, the elastic spring 210 is reset, and the laser auxiliary plate 211 is reset accordingly. The protective gas pipe 207 is used by an external pump to send the protective gas into the transparent protective shell 212, which can prevent the part from being oxidized during the galvanometer welding process, and can also improve the welding quality and reduce welding defects.

[0027] When the transparent protective shell 212 squeezes the sliding column 301 and the pressure plate 302 downward, the sliding column 301 moves downward along the sliding shell 303, and the telescopic plate 304 and the telescopic spring 306 begin to move downward under the force of the sliding column 301. When the telescopic plate 304 moves down a distance along the plate shell 305, it touches the connecting block 307. The connecting block 307 is forced to drive the arched short button plates 308 on both sides to move downward. The arched short button plates 308 move downward and drive the small knob plates 309 to push the arched long button plates 310 to move away from the connecting block 307. The arched long button plates 310 move and push the bottom of the long concave plates 311 away from the connecting block 307. The long concave plates 311 want the arched middle button plates 312 to rotate. The top of the long concave plates 311 moves toward the sliding column 301. The long concave plates 311 push the shaft connecting plates 313 to move toward the sliding column 301. The shaft connecting plates 313 drive the arched button plates 314 to move toward the sliding column 30 1 moves, the arched button plate 314 pushes the telescopic column 315 to move toward the sliding column 301, the telescopic column 315 drives the support plate 316 to move toward the sliding column 301, the support plate 316 moves and drives the arched thin button plate 317 to move toward the sliding column 301, the arched thin button plate 317 drives the small connecting plate 318 and the arc clamping plate 320 to move toward the sliding column 301, the small connecting plate 318 drives the auxiliary rotating block 319 to move toward the sliding column 301, and the telescopic column 315 drives the baffle plate 321 to move toward the sliding column 301. When the parts are touched, the parts squeeze the auxiliary rotating block 319, the auxiliary rotating block 319 is deflected by the force, and drives the small connecting plate 318 and the arc clamping plate 320 to shrink inward. After the parts are clamped, the auxiliary rotating block 319, the small connecting plate 318 and the arc clamping plate 320 stop shrinking, and the parts are further fixed, which makes welding more convenient and effectively improves the welding efficiency;

[0028] When the telescopic plate 304 moves downward, the gas inside the plate shell 305 is compressed into the inside of the air pressure tube 404, and the gas flows into the inside of the oil tank 401 along the air pressure tube 404. The liquid inside the oil tank 401 flows into the inside of the oil pipeline 402 under the pressure of the gas, and the air pressure valve inside the oil pipeline 402 is forced to open, and the liquid flows into the groove of the oil tank 403 along the inside of the oil pipeline 402, and lubricates the connection part between the sliding column 301 and the workbench 1, which plays a protective role and prevents the sliding column 301 from moving too far. The surface is mostly damaged, which saves resources. When the sliding column 301 moves downward, air pressure is generated inside the sliding shell 303, and the gas inside the sliding shell 303 enters the interior of the ventilation pipe 406 along the air outlet semicircular plate 407. The gas is blown toward the surface of the part along the ventilation pipe 406, and the dust and fine welding slag attached to the surface of the part are cleaned, so as to prevent the welding slag from falling onto the top surface of the sliding column 301 and affecting the flatness of the parts, thereby improving the welding efficiency and welding quality. The air inlet arc plate 405 sends external air into the interior of the sliding shell 303.
