Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a protective device for a laser welding machine. Background Technique

[0002] Laser welding is a high-precision and high-efficiency welding method. The energy of a laser beam is used to heat two or more workpieces to the melting point, and then they are melted together to form a weld seam. The laser beam of laser welding can be focused to a very small point, enabling precise control of the weld seam during the welding process to ensure welding quality. Laser welding is fast and can complete a large number of welding operations in a very short time, improving production efficiency.

Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] In the embodiment, it is given by Figure 1-6 A protective device for a laser welding machine. The present utility model includes a processing table 1, a protective cover 2 is fixedly connected to the top of the processing table 1, an air jet tube 3 is fixedly connected to the inside of the protective cover 2, an air pump 4 located outside the protective cover 2 is fixedly connected to the outside of the air jet tube 3, an air spray pipe 5 is fixedly connected to the bottom of the air jet tube 3, a clamping assembly 6 is fixedly connected to the top of the processing table 1, a filter box 7 is fixedly connected to the top of the processing table 1, a suction frame 8 is fixedly connected to the left side of the filter box 7, a fan 9 is fixedly connected to the rear side of the filter box 7, a filter plate 10 is fixedly connected to the inside of the filter box 7, an activated carbon box 11 located on the right side of the filter plate 10 is fixedly connected to the inside of the filter box 7, and the protective cover 2 is made of transparent glass material.

[0027] After the object is fixed inside the clamping assembly 6 and the welding is completed, since the surface temperature of the object is relatively high during welding, at this time, the air pump 4 is started. The air pump 4 inputs the outside air into the inside of the air jet tube 3, and then sprays it onto the surface of the object through the air spray pipe 5 to cool the surface of the object, and at the same time blows the welding slag on the surface of the object to the right. The fan 9 is started, and the fan 9 sucks the harmful gases generated by welding and the welding slag from the suction frame 8 and enters the inside of the filter box 7. Then, the slag is filtered by the filter plate 10, and the harmful gases are adsorbed by the activated carbon box 11 and discharged from the protective cover 2 after filtration.

[0028] Specifically, referring to Figure 1 andFigure 2 , inside the protective cover 2, a laser welding machine body 12 is fixedly connected, and a sliding cover 13 is slidably connected inside the protective cover 2.

[0029] In this embodiment, by sliding the sliding cover 13 upwards, an object is placed inside the clamping assembly 6 for clamping and fixing. The sliding cover 13 slides downwards to seal the protective cover 2, and then the object is welded. After welding is completed, the sliding cover 13 slides upwards to take out the object.

[0030] Specifically, referring to Figure 1 , on the outside of the protective cover 2, an electric push rod 14 is fixedly connected, and the output end of the electric push rod 14 is fixedly connected to the sliding cover 13.

[0031] In this embodiment, the electric push rod 14 is started, which drives the sliding cover 13 to slide upwards, thereby facilitating the placement of the object inside the protective cover 2 for welding. The protective cover 2 and the sliding cover 13 protect the welding process, preventing the filter slag and sparks generated by welding from splashing everywhere.

[0032] Specifically, referring to Figure 3 and Figure 6 , the clamping assembly 6 includes a fixed frame 15 fixedly connected to the top of the processing table 1. Inside the processing table 1, a rotating column 16 is rotatably connected. At the top of the rotating column 16, a rotating piece 17 rotatably connected inside the fixed frame 15 is fixedly connected. Inside the fixed frame 15, a fixing plate 18 is slidably connected, and at the top of the fixing plate 18, a sliding column 19 slidably connected inside the rotating piece 17 is fixedly connected.

[0033] In this embodiment, the rotating column 16 is rotated, which drives the rotating piece 17 to rotate, causing the fixing plate 18 to slide inside the fixed frame 15 and move closer to each other, so that the object on the top of the fixed frame 15 is fixed by the fixing plate 18.

[0034] Specifically, referring to Figure 5 and Figure 6 , inside the rotating piece 17, a sliding hole 20 is formed. The number of sliding holes 20 is four and they are distributed in a circular array. The sliding hole 20 is slidably connected to the outside of the sliding column 19. Inside the fixed frame 15, a square hole 21 is formed, and the fixing plate 18 is slidably connected to the inside of the square hole 21.

[0035] In this embodiment, the rotating column 16 drives the rotating piece 17 to rotate, causing the sliding hole 20 to rotate, driving the sliding column 19 to slide. The sliding column 19 makes the four fixing plates 18 move closer to or away from each other, thereby fixing or releasing the outside of the object, facilitating welding of the object or taking out the object.

[0036] Specifically, referring to Figure 1 , Figure 3 and Figure 4, a gear 22 is fixedly connected to the bottom of the rotating column 16, a cylinder 23 is fixedly connected to the bottom of the processing table 1, and a rack 24 meshing with the gear 22 is fixedly connected to the output end of the cylinder 23. A control panel 25 is fixedly connected to the top of the processing table 1.

[0037] In this embodiment, the cylinder 23 is started, so as to drive the rack 24 to slide. Subsequently, the gear 22 rotates to drive the rotating column 16 to rotate, so that the rotating piece 17 drives the fixing plate 18 to approach or move away from each other. The control panel 25 controls the fixing, welding, cooling of the object, and the absorption of harmful gases and welding slag.

[0038] Working principle:

[0039] First: The electric push rod 14 is started, so as to drive the sliding cover 13 to slide upward, thereby facilitating the placement of the object into the protective cover 2 for welding. The protective cover 2 and the sliding cover 13 protect the welding process to prevent the welding slag and sparks from splashing everywhere. At this time, the air pump 4 is started, and the air pump 4 inputs the external air into the inside of the air jet tube 3, and then sprays it onto the surface of the object through the air spray pipe 5 for cleaning, blowing the welding slag on the surface of the object to the right to avoid affecting subsequent welding treatment. When the welding of the object fixed inside the clamping assembly 6 is completed, at the same time, the fan 9 is started, and the fan 9 sucks the harmful gases and part of the welding slag generated by welding from the air suction frame 8 and enters the inside of the filter box 7. Subsequently, the slag is filtered by the filter plate 10, and the harmful gases are adsorbed by the activated carbon box 11 and then discharged from the protective cover 2 after filtration.
