Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a laser welding machine with positioning and clamping functions. Background Art

[0002] Laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation diffuses into the interior of the material through heat conduction, melting the material to form a specific molten pool. It is a new type of welding method, mainly for welding thin-walled materials and precision parts, and can realize spot welding, butt welding, stack welding, sealing welding, etc.

[0003] At present, before laser welding of materials, it is necessary to use a clamping tool to clamp the material. The firm clamping makes it easier to weld the material accurately. However, when welding the bottom of the material, it is often necessary to remove the bolts and other accessories on the clamping tool, then turn the part over, and then continue to install the bolts and other accessories before welding the bottom of the material. This can easily cause the position where the two materials have just been welded to break, resulting in the need for re-welding. In addition, the reciprocating removal and installation of bolts and other accessories results in a slow welding speed. Therefore, a laser welding machine with a positioning and clamping function is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-4A laser welding machine with positioning and clamping functions comprises a bottom plate 1, two connecting rods 14 are arranged on the top of the bottom plate 1, connecting shafts 15 are fixedly installed on the sides of the two connecting rods 14 close to each other, round shafts 19 are arranged on the top sides of the two connecting rods 14 close to each other, clamping plates 20 are fixedly connected on the sides of the two round shafts 19 close to each other, multiple threaded grooves 24 are provided on the sides of the two clamping plates 20 away from each other, mounting plates 22 are fixedly installed on the top sides of the two connecting rods 14, threaded holes 23 are provided on the two mounting plates 22, threaded columns 25 are threadedly installed in the two threaded holes 23, and the other ends of the two threaded columns 25 are threadedly installed in one of the multiple threaded grooves 24, and an adjusting screw is arranged on one side of the two connecting rods 14. A joint assembly, a moving assembly is arranged above the base plate 1, and a laser welding machine body 8 is arranged below the moving assembly. When the bottom of the part needs to be welded, the two threaded columns 25 are rotated counterclockwise to disengage the two threaded columns 25 from the clamping plates 20. Because a circular shaft 19 is arranged between the two clamping plates 20 and the two connecting rods 14, under the action of the circular shaft 19, the clamping plates 20 can be flipped by grabbing the handle fixedly installed on one side of the clamping plates 20. When the unwelded area of ​​the bottom is turned over, the two threaded columns 25 can be rotated clockwise to thread the other ends of the two threaded columns 25 into the two clamping plates 20 respectively, so that the mounting plate 22 is fixedly connected with the clamping plates 20 to avoid the clamping plates 20 from rotating during the welding process.

[0022] Specifically, the adjustment component includes two support blocks 9 fixedly installed on the top side of the base plate 1, and the same mounting frame 10 is fixedly installed on the top sides of the two support blocks 9. The mounting frame 10 is U-shaped, and two guide rods 11 are fixedly installed on the inner walls of both sides of the mounting frame 10. The outer sides of the two guide rods 11 are respectively slidably installed with a first guide block 12 and a second guide block 13. One side of two connecting rods 14 is respectively fixedly connected to one side of the first guide block 12 and the second guide block 13. The two connecting rods 14 are both L-shaped and symmetrically arranged. An electric push rod 16 is fixedly installed on one side of the mounting frame 10. The output end of the electric push rod 16 passes through the mounting frame 10 and is fixedly connected to a connecting seat 17. Two linkage rods 18 are movably sleeved in the connecting seat 17. The other ends of the two linkage rods 18 are respectively movably sleeved in two connecting shafts 15. The two linkage rods 18 are symmetrically arranged. By starting the electric The push rod 16 drives the connecting seat 17 to move backward. When the connecting seat 17 moves backward, the two linkage rods 18 drive the two connecting shafts 15 to approach each other. Because the two connecting shafts 15 are respectively fixedly installed on the side where the two connecting rods 14 are close to each other, when the two connecting shafts 15 are pulled by the two linkage rods 18, the two connecting rods 14 can be brought close to each other, so that the two clamps 20 clamp the two sides of the part. When the two connecting rods 14 are close to each other, they can drive the first guide block 12 and the second guide block 13 to approach each other. The first guide block 12 and the second guide block 13 are set to play a limiting role when the two connecting rods 14 move. The electric push rod 16 drives the connecting seat 17 to move forward or backward, so that the two clamps 20 are close to or away from each other, so that parts of different sizes can be clamped.

[0023] Specifically, the moving component includes two cylinders 2 fixedly installed on the top side of the base plate 1, the output ends of the two cylinders 2 are fixedly connected to the same top plate 3, the top plate 3 is provided with a long groove, a threaded motor 4 is fixedly installed on one side of the top plate 3, the output end of the threaded motor 4 rotates through the top plate 3 and is fixedly installed with a threaded rod 5, the threaded rod 5 is rotatably connected to the inner wall of one side of the long groove, a slider 6 is slidably installed on the outer side of the threaded rod 5, a connecting plate 7 is fixedly installed on the bottom side of the slider 6, and a laser welding machine body 8 is fixedly connected to the bottom side of the connecting plate 7. By starting the threaded motor 4, the laser welding machine body 8 under the slider 6 is driven to move to the top of the part, and then the top plate 3 is driven downward by the two cylinders 2, the laser welding machine body 8 can contact the welding position of the part, and then the part can be welded, and if the welding position deviates, the slider 6 can continue to be driven to move back and forth by the threaded motor 4, so that the welding position can be adjusted.

[0024] Specifically, a protection pad 21 is fixedly installed on one side of the two clamps 20 that are close to each other. The two protection pads 21 are symmetrically arranged. Through the arrangement of the protection pads 21, when the clamps 20 clamp both sides of the parts, it can prevent the clamps 20 from causing damage to both sides of the parts.

[0025] The laser welding machine with positioning and clamping function is connected to 220V mains electricity, and the main controller can be a conventional known device for control such as a computer.

[0026] When in use: the parts to be welded are placed between the two clamping plates 20, and then the electric push rod 16 is started to drive the connecting seat 17 to move backward. When the connecting seat 17 moves backward, the two linkage rods 18 drive the two connecting shafts 15 to approach each other. Because the two connecting shafts 15 are respectively fixedly installed on the side where the two connecting rods 14 are close to each other, when the two connecting shafts 15 are pulled by the two linkage rods 18, the two connecting rods 14 can be brought close to each other, so that the two clamping plates 20 clamp the two sides of the parts. When the two connecting rods 14 are close to each other, they can drive the first guide block 12 and the second guide block 13 to approach each other. The first guide block 12 and the second guide block 13 can play a limiting role when the two connecting rods 14 move. The protective pad 21 can prevent the clamping plate 20 from causing damage to the two sides of the parts when the clamping plate 20 clamps the two sides of the parts. The electric push rod 16 drives the connecting seat 17 to move forward or backward, so that the two clamping plates 20 are close to or away from each other, so that parts of different sizes can be welded. The laser welding machine body 8 is clamped. After the clamping is completed, the laser welding machine body 8 under the slider 6 is driven to move to the top of the part by starting the threaded motor 4, and then the top plate 3 is driven downward by the two cylinders 2, and the laser welding machine body 8 can contact the welding position of the part, and then the part can be welded. If the welding position deviates, the slider 6 can continue to be driven to move back and forth by the threaded motor 4, so that the welding position can be adjusted. When it is necessary to weld the bottom of the part, the two threaded columns 25 are rotated counterclockwise to disengage the two threaded columns 25 from the clamping plate 20, and because a circular shaft 19 is provided between the two clamping plates 20 and the two connecting rods 14, under the action of the circular shaft 19, the handle fixedly installed on one side of the clamping plate 20 can be grasped to drive the clamping plate 20 to flip. When the unwelded area at the bottom is turned over, the two threaded columns 25 can be rotated clockwise to thread the other ends of the two threaded columns 25 in the two clamping plates 20, respectively, so that the mounting plate 22 is fixedly connected with the clamping plate 20 to avoid the clamping plate 20 from rotating during the welding process.
