Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a shot peening enhanced laser welding device. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. It is an important application of laser materials processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction type, meaning that laser radiation heats the surface of the workpiece, and the surface heat diffuses inward through heat conduction. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the workpiece is melted, forming a specific molten pool.

[0003] A patent search revealed a document titled "A Laser Welding Machine for Plates" (publication number "CN211361032U"). This document describes a device that welds the weld seam of a plate using a laser welding machine. However, it cannot perform shot peening on the inside of the weld seam, resulting in lower weld strength and affecting the overall welding effect. Therefore, this invention designs a shot peening-enhanced laser welding device to solve the aforementioned problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a shot peening and laser welding device includes an operating table 1, a frame 2 fixedly fitted outside the operating table 1, a laser welding machine 3 fixedly mounted on the top of the frame 2, and a welding head 4 fixedly mounted on the bottom of the laser welding machine 3 penetrating the frame 2. A box 5 is fixedly mounted on the rear top of the frame 2, a discharge pipe 6 is fixedly mounted on the lower right side inside the box 5, and a solenoid valve 7 rotatably passes through the discharge pipe 6. An installation sleeve 8 is fixedly mounted on the left side inside the frame 2, a connecting pipe 9 is fixedly mounted on the left side inside the frame 2, and a connector 10 is fixedly mounted on the bottom inside the installation sleeve 8. A drive assembly 11 is provided inside the operating table 1, and the drive assembly 11 includes a first [missing information - likely a type of component] fixedly mounted on the left side outside the operating table 1. The first motor 1101 has a rotating rod 1102 fixed on the right side of the first motor 1101 that rotates through the operating table 1. The support plate 1103 slidably connected to the top of the operating table 1 is threaded onto the outside of the rotating rod 1102. Limiting plates 1104 are fixed on the left and right sides of the top front end of the support plate 1103, and a top rod 1105 is threaded through the top of the limiting plate 1104. The discharge pipe 6, welding head 4, and connector 10 are designed to correspond to each other. A goggle 12 is fixed on the upper front side of the inside of the frame 2. A controller 13 is set on the outer wall of the frame 2. The controller 13 is connected to the laser welding machine 3, the solenoid valve 7, and the first motor 1101 through wires.

[0028] The worker first places the sheet metal on the support plate 1103, aligning the weld seam of the sheet metal with the weld joint 4. The worker then rotates the push rod 1105, applying clamping force to the top of the sheet metal, thus securing the sheet metal to the support plate 1103. Next, the worker uses the controller 13 to activate the first motor 1101, a geared motor, which drives the rotating rod 1102 to rotate. Through the threaded transmission design between the rotating rod 1102 and the support plate 1103, the support plate 1103... The plate is moved to the left along the direction of the operating table 1. Simultaneously, the operator can observe the movement of the plate through goggles 12. When the weld seam of the plate is about to reach the position of the discharge pipe 6, the operator opens the solenoid valve 7. At this time, the tiny metal particles inside the box 5 are discharged into the weld seam through the discharge pipe 6. When the weld seam reaches the welding head 4, the operator turns on the laser welding machine 3, so that the welding head 4 welds the tiny metal particles inside the weld seam of the plate. Through this method, the strengthening effect of shot peening laser welding is achieved. In addition, the operator can pre-connect the connecting pipe 9 to an external tank containing nitrogen or argon gas, and then open the tank. This allows the gas to be discharged from the connecting pipe 9 through the mounting sleeve 8 and the connecting head 10 to the welding area of ​​the plate. By supplying protective gas to the welding area, weld oxidation is prevented, ensuring welding quality.

[0029] Example 2

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a second motor 14 is installed on the right side of the rear end of the frame 2. A connecting rod 15 is connected to the front end of the second motor 14. The connecting rod 15 rotates through the frame 2, and the second motor 14 is connected to the controller 13 via a wire. A detachable roller sleeve 16 is fixedly fitted on the outside of the connecting rod 15. The roller sleeve 16 is located between the welding head 4 and the discharge pipe 6. Guide holes 17 are integrally provided at both the front and rear ends of the left side of the operating table 1. The guide holes 17 are through holes. A slide plate 18 slides inside the guide holes 17. A baffle 19 slides inside the slide plate 18. The baffle 19 is horizontally visible from the front. The cross-section is designed in an L-shape. The external thread of the slide plate 18 is threaded through the top pin 20. The baffle 19 is set at the front and rear ends of the outside of the discharge pipe 6, and there are two baffles 19. The two baffles 19 are designed to be parallel to each other. The bottom left side of the operating table 1 is fixed with mounting plates 21 at the front and rear ends. The mounting plates 21 correspond to the slide plates 18 one by one. The mounting plates 21 are connected to the screws 22. The screws 22 are threaded through the slide plates 18. The front slide plate 18 and the screws 22 are connected by left-hand thread, and the rear slide plate 18 and the screws 22 are connected by right-hand thread.

[0031] According to the operation method in Embodiment 1, the operator can turn on the second motor 14, which drives the connecting rod 15 to rotate the roller sleeve 16. When the tiny metal particles are discharged into the weld, they are in an accumulated state. When the tiny metal particles move to the position of the roller sleeve 16, the rotating roller sleeve 16 can assist in compacting the accumulated tiny particles, ensuring the effect of the tiny particles filling the weld. In addition, the baffle 19 can guide the tiny particles into the weld. Depending on the actual use, the operator can pull the baffle 19. This ensures that the bottom surface of the baffle 19 contacts the top surface of the plate, guaranteeing that the baffle 19 can be used with plates of different thicknesses. Then, the top pin 20 is rotated to apply clamping force to the baffle 19, thereby locking the height-adjusted state of the baffle 19. In addition, the operator can rotate the screw 22. Through the threaded transmission design between the screw 22 and the slide plate 18, two slide plates 18 can drive the corresponding baffles 19 to move in opposite directions or away from each other, thereby matching the spacing between the two baffles 19 with welds of different widths.
