Technical Field
[0001] The utility model belongs to the technical field of laser welding, and particularly relates to a high-energy pulsed fiber laser welder. Background Technique
[0002] Laser welding is to use high-energy laser pulses to locally heat materials in a small area. The energy of laser radiation diffuses into the interior of the materials through heat conduction, melting the materials 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, lap welding, seal welding, etc. A fiber laser welder is a laser welding device that couples a high-energy laser beam into an optical fiber. After long-distance transmission, it is collimated into parallel light by a collimating mirror and then focused on the workpiece for welding. It has the advantages of fast welding speed, small penetration depth, small heat-affected zone, and high weld quality.
[0003] However, there are some problems in the prior art: Although the existing fiber laser welders have better welding effects than ordinary welding equipment, in actual use, since workers often need to weld two plates to be welded into a workpiece with a certain bending angle, when using a fiber laser welder for welding, it is necessary to hold the two plates by hand and pose them at a certain angle for welding, which increases the welding difficulty and reduces the operation safety. Therefore, we propose a high-energy pulsed fiber laser welder. Summary of the Utility Model
[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a high-energy pulsed fiber laser welder, which reduces the welding difficulty by automatically posing two plates at a certain angle for welding.

A slider is slidably connected to the gantry. A laser welding head is arranged on the slider. Vertical plates are fixedly installed on both sides of the top of the base. A round shaft is fixedly installed on the vertical plate. A bracket is rotatably connected between the two round shafts. A clamping mechanism is arranged on the bracket. A driving mechanism is arranged between the bracket and the vertical plate.
[0006] Optionally, a push rod is fixedly installed on the slider, and the laser welding head is fixedly connected to the telescopic end of the push rod.
[0007] Optionally, the driving mechanism includes a first braking motor fixedly installed on the back of the rear vertical plate.

[0008] Optionally, a driving gear is fixedly sleeved on the outer surface of the rotating shaft, a driven gear is fixedly sleeved on the outer surface of the rotating rod, and the driven gear is meshed with the driving gear.
[0009] Optionally, the clamping mechanism includes a vertical rod movably inserted into the bracket. A pressing plate is rotatably connected to the top of the vertical rod. A cross plate is fixedly connected to the bottom of the vertical rod. A second braking motor is fixedly installed at the bottom of the bracket. The output shaft of the second braking motor is fixedly sleeved with a rotating shaft, and an eccentric wheel is fixedly connected to the other end of the rotating shaft. The eccentric wheel is in contact with the surface of the cross plate.

[0014] Optionally, the number of the swing rods is two, and the two swing rods are symmetrically arranged.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] 1. By providing a round shaft, a bracket and a driving mechanism, before welding work, if a worker needs to weld two plates at a certain angle, the driving mechanism can be used to make the bracket rotate around the round shaft, so that an included angle is formed after the two brackets rotate. Then the worker places the two plates on the brackets and then performs the welding work. The plates can be welded at a certain angle without the need for manual support of the plates, thereby reducing the welding difficulty and improving the operation safety of the worker.
[0017] 2. By providing a second braking motor, an eccentric wheel, a cross plate, a first spring, and a vertical rod, the present utility model enables the rotating shaft to drive the eccentric wheel to rotate by starting the second braking motor.

[0027] Furthermore, an electric push rod 28 is fixedly installed on the slider 4, and the laser welding head 5 is fixedly connected to the telescopic end of the electric push rod 28.
[0028] Furthermore, the driving mechanism includes a first brake motor 9, the first brake motor 9 is fixedly installed on the back of the vertical plate 6 at the rear end, the output shaft of the first brake motor 9 is fixedly sleeved with a rotating shaft 10, a rotating rod 11 is rotatably connected to the vertical plate 6 on the left side of the rotating shaft 10, swing rods 12 are fixedly connected to the front ends of the rotating shaft 10 and the rotating rod 11 respectively, a square frame 13 is fixedly installed at the bottom of the bracket 8, and a round block 14 located inside the square frame 13 is fixedly connected to the swing rod 12.
[0029] Furthermore, a driving gear 15 is fixedly sleeved on the outer surface of the rotating shaft 10, a driven gear 16 is fixedly sleeved on the outer surface of the rotating rod 11, and the driven gear 16 is meshed with the driving gear 15.
[0030] By starting the first brake motor 9, the rotating shaft 10 can be rotated, so that the driving gear 15 can drive the driven gear 16 to rotate, and then the swing rods 12 on both sides can drive the round block 14 to rotate, so that the round block 14 presses against the inner wall of the square frame 13, and thus the two brackets 8 can rotate towards each other, adjusting the angle between the two brackets 8, so as to facilitate the staff to weld two plates into a plate with a certain bending angle according to needs.
[0031] Furthermore, the clamping mechanism includes a vertical rod 17, the vertical rod 17 is movably inserted into the bracket 8, a pressing plate 18 is rotatably connected to the top of the vertical rod 17, a cross plate 19 is fixedly connected to the bottom of the vertical rod 17, a second brake motor 20 is fixedly installed at the bottom of the bracket 8, the output shaft of the second brake motor 20 is fixedly sleeved with a rotating shaft 21, and an eccentric wheel 22 is fixedly connected to the other end of the rotating shaft 21, and the eccentric wheel 22 is attached to the surface of the cross plate 19.
[0032] By starting the second brake motor 20, the rotating shaft 21 can drive the eccentric wheel 22 to rotate, so that the cross plate 19 can drive the pressing plate 18 to move downward through the vertical rod 17, and then the pressing plate 18 can clamp and fix the plate, ensuring the stability of the plate during welding.
[0033] Furthermore, a first spring 23 is movably sleeved on the outer surface of the vertical rod 17 , and two ends of the first spring 23 are fixedly connected to the bracket 8 and the horizontal plate 19 respectively.
[0034] By setting the first spring 23 to a stretched state, the pressure plate 18 will tend to move upward due to the elastic recovery effect of the first spring 23, so that it can move upward when the clamping effect on the plate is released, making it easier to remove the plate.
[0035] Furthermore, a fixing block 24 is fixedly installed on the top of the pressing plate 18 , a latch 25 is movably plugged into the fixing block 24 , and a pull handle 26 is fixedly connected to the latch 25 .
[0036] When the two plates are welded into a plate with a certain bending angle, even if the pressing plate 18 releases the fixation on the plate, the plate cannot be removed. At this time, the staff can pull the handle 26 to pull the latch 25 to release the limit on the pressing plate 18, and then rotate the pressing plate 18 with the vertical rod 17 as the axis, and rotate the pressing plate 18 from the top of the plate to the side of the plate, so that the welded plate can be removed.
[0037] Furthermore, a second spring 27 is movably sleeved on the outer surface of the latch 25 , and two ends of the second spring 27 are fixedly connected to the fixing block 24 and the pull handle 26 , respectively.

[0039] Furthermore, the pressing plate 18 has a square appearance, and anti-slip grooves are provided on the bottom of the pressing plate 18 .
[0040] Furthermore, there are two rocker arms 12 , and the two rocker arms 12 are symmetrically arranged.
[0041] Working principle: During use, if the staff needs to weld two plates into a plate with a bending angle, they can start the first brake motor 9. Due to the operation of the first brake motor 9, the rotating shaft 10 will rotate, so that the active gear 15 can drive the driven gear 16 to rotate, and then the two rocker arms 12 can drive the two round blocks 14 to rotate, so that the two brackets 8 can rotate towards each other. After adjusting the angle of the bracket 8, the staff can place the two plates on the bracket 8 respectively, and then start the second brake motor 20. Due to the operation of the second brake motor 20, the rotating shaft 21 can drive the eccentric wheel 22 to rotate, so that the horizontal plate 19 can drive the vertical rod 17 and the pressure plate 18 to move downward and stretch the first spring 23, so that the pressure plate 18 can clamp and fix the plate placed on the bracket 8, so as to ensure the stability of subsequent welding, and then the position of the laser welding head 5 can be adjusted by the gantry 3, the slider 4 and the electric push rod 28 to perform welding.
