[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) This laser welding device has an adjustable wrapping and protection structure. The adjustable wrapping and protection structure can automatically perform wrapping and protection when the water pump moves to the welding position, which can avoid the impact of welding sparks, strong light, toxic and harmful gases and dust on the physical health of workers. At the same time, the automatically adjustable wrapping and protection structure effectively improves the performance of the welding device. At the same time, the structure of this laser welding device is simply designed, easy to use and operate, stable and reliable in adjustment and protection, and its performance can meet the use requirements of water pump welding processing;

[0015] (2) When the top plate horizontally moves on the top of the fixed vertical plate, it will drive the inverted U-shaped enclosing plate to move horizontally. The horizontal movement of the inverted U-shaped enclosing plate will cause the inverted U-shaped enclosing plate to move upward on the top plate through the two inclined grooves and the two adjusting pins, so that the inverted U-shaped enclosing plate can stably move upward inside the inverted T-shaped chute through the inverted T-shaped slider, the first roller and the ball. Finally, most of the inverted U-shaped enclosing plate moves above the top plate, so that the robotic arm and the laser welding gun are exposed;

[0016] Before welding, the horizontal movement of the top plate drives the inverted U-shaped enclosing plate to move horizontally and downward. Finally, the fixed vertical plate, the top plate and the inverted U-shaped enclosing plate enclose and wrap the robotic arm and the laser welding gun; at the same time, by turning on the dust suction fan, the toxic and harmful gases and dust generated by welding are conveyed to the external dust purification equipment through the hose for treatment, and the welding situation can be effectively observed through the welding filter, and the welding filter can avoid the harm of strong light to the eyes of workers;

[0017] (3) When the two small worm wheels rotate relative to each other to drive the two first transmission shafts to rotate, the rotation of the two first transmission shafts will drive the first gears at their tops to rotate relative to each other. The relatively rotating first gears will drive the two toothed plates to move, so that the top plate rolls inside the T-shaped groove through the second rollers, enabling the top plate to move horizontally stably and effectively.

[0018] (4) During use, the water pump component is installed on the top of the workpiece placement table through a fixture; by starting the forward and reverse motor, the second transmission shaft rotates. The rotation of the second transmission shaft will drive the two turntables and the two arc-shaped transmission teeth to rotate. The rotation of the two arc-shaped transmission teeth will drive the two second gears to rotate, causing the third transmission shaft and the two large worm gears to rotate. The rotation of the large worm gears will drive the small worm wheels to rotate, so that the top plate moves stably horizontally on the top of the fixed vertical plate; when the top plate moves horizontally on the top of the fixed vertical plate, it will drive the inverted U-shaped enclosure plate to move horizontally and move upward. Finally, the workpiece placement table and the water pump component are exposed. Then, the two arc-shaped transmission teeth will separate from the two second gears;

[0019] Then, the two rotating arc-shaped transmission teeth will drive the two third gears to rotate, causing the fourth transmission shaft and the two first bevel gears to rotate. The rotation of the two first bevel gears will drive the two second bevel gears to rotate, causing the two large pitch screw rods to rotate. The rotation of the two large pitch screw rods will move the two adjusting blocks, driving the workpiece placement table and the fixed water pump to move, so that the workpiece placement table drives the fixed water pump component to move to the other end of the top of the welding table, facilitating the disassembly of the water pump component and the installation of the components to be welded.

A welding processing space can be enclosed by the fixed vertical plate 2, the top plate 3, and the inverted U-shaped enclosing plate 4, so that the welding sparks, strong light, toxic and harmful gases, and dust will not affect the staff. An automatically adjustable robotic arm is installed at the top of the welding table 1 in the enclosed space formed by the fixed vertical plate 2, the top plate 3, and the inverted U-shaped enclosing plate 4. A laser welding gun is installed at the end of the robotic arm.

[0032] A welding filter 5 is installed in the middle of the inverted U-shaped enclosing plate 4. Inclined lifting adjustment components are connected between the top of the welding table 1 and the two side edges of the inverted U-shaped enclosing plate 4. A dust suction port 6 is formed in the middle of the top plate 3. A dust suction fan 7 located above the dust suction port 6 is installed at the top of the top plate 3. A hose 8 connected to an external dust purification device is installed on the dust suction fan 7. Two transmission inner grooves 9 are symmetrically formed inside one end of the welding table 1. An intermittent transmission component is installed between the two transmission inner grooves 9. The intermittent transmission component is in transmission connection with the horizontal telescopic adjustment component and the workpiece placement table 102. A forward and reverse motor 10 connected to the intermittent transmission component is installed on one side of the welding table 1.

[0033] This laser welding device has an adjustable wrapping protection structure. The adjustable wrapping protection structure can automatically perform wrapping protection when the water pump moves to the welding position, which can prevent welding sparks, strong light, toxic and harmful gases, and dust from affecting the physical health of workers. At the same time, the automatically adjustable wrapping protection structure effectively improves the performance of the welding device. At the same time, the structure of this laser welding device is simply designed, easy to use and operate, stable and reliable in adjustment and protection, and its performance can meet the use requirements of water pump welding processing.

[0034] Embodiment 2: On the basis of Embodiment 1, two inverted T-shaped chutes 11 are formed on both sides inside the inverted U-shaped enclosing plate 4. Two inverted T-shaped sliders 12 slidably installed inside the two inverted T-shaped chutes 11 are fixedly installed on both sides of the top plate 3. First rollers 13 are installed at both ends of the inverted T-shaped sliders 12 located inside the inverted T-shaped chutes 11. Ball bearings 14 in contact with the inverted T-shaped chutes 11 are installed on both sides of the middle of the inverted T-shaped sliders 12, so that the inverted U-shaped enclosing plate 4 can perform stable and effective lifting movement.

[0035] The tilting and lifting adjustment component includes fixing plates 15 symmetrically and fixedly installed on the top of the welding table 1. Tilt grooves 16 are symmetrically formed on both sides outside the inverted U-shaped enclosing plate 4. On the upper parts of the opposite sides of the two fixing plates 15, adjusting pins 17 inserted into the two tilt grooves 16 are fixedly installed, so that the inverted U-shaped enclosing plate 4 can be tilted and lifted for adjustment.

[0036] Specifically, as shown in the attached drawing, when the top plate 3 horizontally moves on the top of the fixed vertical plate 2, it will drive the inverted U-shaped enclosing plate 4 to move horizontally. The horizontal movement of the inverted U-shaped enclosing plate 4 will cause the inverted U-shaped enclosing plate 4 to move upward on the top plate 3 through the two tilt grooves 16 and the two adjusting pins 17, so that the inverted U-shaped enclosing plate 4 stably moves upward inside the inverted T-shaped sliding groove 11 through the inverted T-shaped sliding block 12, the first roller 13 and the ball 14. Finally, most of the inverted U-shaped enclosing plate 4 moves above the top plate 3, so that the robotic arm and the laser welding gun are exposed.

[0037] On the contrary, before welding, the horizontal movement of the top plate 3 drives the inverted U-shaped enclosing plate 4 to move horizontally and move downward. Finally, the fixed vertical plate 2, the top plate 3 and the inverted U-shaped enclosing plate 4 enclose and wrap the robotic arm and the laser welding gun. At the same time, by turning on the dust suction fan 7, the toxic and harmful gases and dust generated by welding are conveyed through the hose 8 to the external dust purification equipment for treatment, and the welding situation can be effectively observed through the welding filter 5, and the welding filter 5 can avoid strong light from hurting the eyes of workers.

[0038] Embodiment 3, on the basis of Embodiment 1, two T-shaped grooves 18 are symmetrically formed at the bottom of the top plate 3 on both sides of the dust suction port 6. Two triangular blocks 19 are symmetrically and fixedly installed on the upper part of one side of the fixed vertical plate 2. Between the tops of the two triangular blocks 19 and the top of the fixed vertical plate 2, inserting plates 20 are fixedly installed. The two inserting plates 20 are respectively located inside the two T-shaped grooves 18, and second rollers 21 located above the T-shaped grooves 18 are installed on both sides of the inserting plate 20, so that the top plate 3 can be effectively installed and the top plate 3 can stably move horizontally.

[0039] The horizontal telescopic adjustment component includes two transmission grooves 22 symmetrically formed at the bottom of the top plate 3. The two transmission grooves 22 are located on the opposite sides of the two T-shaped grooves 18, and on the sides close to each other inside the two transmission grooves 22, rack plates 23 are fixedly installed. Two pairs of mounting blocks 24 are symmetrically and fixedly installed on one side of the fixed vertical plate 2. Between each pair of mounting blocks 24, a first transmission shaft 25 is rotatably installed. The tops of the two first transmission shafts 25 respectively extend into the two transmission grooves 22 and are fixedly installed with first gears 26 meshed with the rack plates 23. Small worm wheels 27 are symmetrically and fixedly installed at the bottoms of the two first transmission shafts 25, so that the top plate 3 can be effectively driven to move.

[0040] Specifically, when the two small worm wheels 27 rotate relative to each other to drive the two first transmission shafts 25 to rotate, the rotation of the two first transmission shafts 25 will drive the first gears 26 on their tops to rotate relative to each other. The relatively rotating first gears 26 will drive the two toothed plates 23 to move, so that the top plate 3 rolls inside the T-shaped groove 18 through the second rollers 21, and the top plate 3 moves horizontally stably and effectively.

[0041] Embodiment 4: On the basis of Embodiment 3, the intermittent transmission component includes a second transmission shaft 28 rotatably connected between the two transmission inner grooves 9. One end of the second transmission shaft 28 is fixedly connected to the output end of the forward and reverse motor 10. Disk-shaped plates 29 are fixedly installed on the surfaces of the second transmission shaft 28 located inside the two transmission inner grooves 9. Arc-shaped transmission teeth 30 are fixedly installed on the circumferential surfaces of the two disk-shaped plates 29. Notches 31 extending to the top of the welding table 1 are opened in the upper parts of the two transmission inner grooves 9. The two small worm wheels 27 respectively extend into the two notches 31.

[0042] A third transmission shaft 32 is rotatably installed between the two notches 31. Second gears 33 aligned with the arc-shaped transmission teeth 30 are fixedly installed at the ends of the third transmission shaft 32 located inside the two notches 31. The arc-shaped transmission teeth 30 intermittently drive the second gears 33. Large worm gears 34 are symmetrically fixedly installed at the axles of the opposite ends of the two second gears 33. The large worm gears 34 are meshed with the small worm wheels 27, so that the top plate 3 can be intermittently adjusted; a fourth transmission shaft 35 is rotatably installed between the lower parts of the two transmission inner grooves 9. Third gears 36 aligned with the arc-shaped transmission teeth 30 are fixedly installed at the ends of the fourth transmission shaft 35 located inside the two transmission inner grooves 9. First bevel gears 37 are fixedly installed at the axles of the opposite ends of the two third gears 36.

[0043] Two through chutes 38 extending to the bottom of the welding table 1 are symmetrically opened at the bottom of the horizontal groove 101. Large pitch threaded rods 39 are symmetrically rotatably connected inside the two through chutes 38. One ends of the two large pitch threaded rods 39 respectively extend into the two transmission inner grooves 9 and are fixedly installed with second bevel gears 41. The two second bevel gears 41 are respectively meshed with the two first bevel gears 37. Adjusting blocks 40 fixedly connected to the bottom of the workpiece placing table 102 are threadedly connected to the surfaces of the two large pitch threaded rods 39, so that the workpiece placing table 102 can be intermittently moved and adjusted.

[0044] Specifically, during use, the water pump component is installed on the top of the workpiece placing table 102 through a fixture;

[0045] By starting the forward and reverse motor 10, the second transmission shaft 28 is rotated. The rotation of the second transmission shaft 28 drives the two turntables 29 and the two arc-shaped transmission gear blocks 30 to rotate. The rotation of the two arc-shaped transmission gear blocks 30 drives the two second gears 33, causing the third transmission shaft 32 and the two large worm gears 34 to rotate. The rotation of the large worm gears 34 drives the small worm wheels 27 to rotate, enabling the top plate 3 to move stably horizontally on the top of the fixed vertical plate 2.

[0046] When the top plate 3 moves horizontally on the top of the fixed vertical plate 2, it drives the inverted U-shaped enclosure plate 4 to move horizontally and upward. Eventually, the workpiece placement table 102 and the water pump component are exposed. Then, the two arc-shaped transmission gear blocks 30 separate from the two second gears 33.

[0047] Next, the two rotating arc-shaped transmission gear blocks 30 drive the two third gears 36, causing the fourth transmission shaft 35 and the two first bevel gears 37 to rotate. The rotation of the two first bevel gears 37 drives the two second bevel gears 41, causing the two large pitch threaded rods 39 to rotate. The rotation of the two large pitch threaded rods 39 moves the two adjusting blocks 40, driving the workpiece placement table 102 and the fixed water pump to move, so that the workpiece placement table 102 drives the fixed water pump component to move to the other end of the top of the welding table 1, facilitating the disassembly of the water pump component and the installation of the components to be welded.

[0048] After the new water pump component is installed, the workpiece placement table 102 drives it to move towards the fixed vertical plate 2. Then, through the backward movement of the top plate 3 and the inverted U-shaped enclosure plate 4, a closed welding space is formed between the fixed vertical plate 2, the top plate 3, and the inverted U-shaped enclosure plate 4.
