Description

Technical Field

[0001] This utility model relates to the field of laser shock strengthening technology, specifically to an automatic supply device for a constraint layer in laser shock strengthening. Background Technology

[0002] Laser shock peening (LSP) is a surface strengthening technique that utilizes the high-intensity compressive stress shock wave generated when a high-energy pulsed laser beam irradiates a metal to induce impact plastic deformation. LSP is a non-contact processing method, avoiding the mechanical friction and wear of traditional methods, thus ensuring processing accuracy and surface quality. In LSP, the confinement layer is a key component, primarily used to enhance the laser-induced shock wave effect, thereby improving the strengthening effect on the material surface. The confinement layer is a transparent medium, typically water or glass, covering the material surface to limit the plasma expansion generated by the laser energy, thereby converting more energy into shock waves propagating into the material's interior.

[0003] In laser shock peening (LSP), maintaining the enhanced shock wave pressure requires a continuous supply of a water-constrained layer. While the water-constrained layer cools the surface and prevents direct laser ablation, its direct exposure to the high-temperature, high-pressure environment of plasma expansion causes rapid vaporization. Timely replenishment of evaporation losses is necessary to maintain thickness stability; otherwise, the effectiveness of subsequent confinement layers will be compromised. Therefore, we need to propose an automated confinement layer supply device for LSP. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides: an automatic supply device for laser shock-enhanced constraint layer, including a base 1, a placement box 3 mounted on the top of the base 1 via a mounting bracket 2, and circulation supply components for replenishing the water constraint layer connected to both sides of the interior of the placement box 3; a workpiece carrier plate 4 installed in the center of the interior cavity of the placement box 3, side plates 5 connected to both sides of the workpiece carrier plate 4, and positioning components for fixing the workpiece position mounted on the surface of the side plates 5; and assembly frame plates 11 provided on both sides of the workpiece carrier plate 4, with anti-interference components for improving the stability of the water constraint layer detachably mounted on the surface of the assembly frame plates 11.

[0021] It is worth noting that the installation of the mounting frame 2, the placement box 3, the workpiece carrier plate 4, the circulating supply component, the positioning component, and the anti-interference component structure can ensure a continuous supply of water to the water constraint layer, maintain the thickness of the water constraint layer, preserve the effect of enhancing shock wave pressure, further improve the stability of water constraint during the water constraint layer supply process, and effectively reduce interference with laser shock enhancement.

[0022] Specifically, the circulating supply assembly includes a circulating water pump 19 installed inside the mounting frame 2 and a water level detector 16 installed on the inner wall of the mounting frame 2. The output end of the circulating water pump 19 is connected to an inlet pipe 20 communicating with the placement tank 3. A circulating water tank 18 is installed inside the mounting frame 2. A controller module 17 is provided on one side of the circulating water pump 19, and the controller module 17 is electrically connected to the water level detector 16 and the circulating water pump 19. The input end of the circulating water pump 19 is connected to the bottom of the circulating water tank 18 via a pipe, and a return water pipe 21 communicating with the placement tank 3 is connected to one side of the circulating water tank 18.

[0023] Furthermore, the mounting frame 2 serves to support the placement box 3 and houses the controller module 17, the circulating water tank 18, and the circulating water pump 19. The controller module 17 controls the operation of the water level detector 16 and the circulating water pump 19. The water level detector 16 is a structure for real-time monitoring of the water level inside the placement box 3. It can use an OMEGA LVL-3100 resistive sensor, which is a publicly available technology. Therefore, there are no restrictions on the use of the sensor. Those skilled in the art can replace it with different types of sensors to monitor the water level and prevent overflow. The overall height of the water constraint layer is higher than that of the anti-interference frame 12. Water enters from the top of the anti-interference frame 12. When the water constraint layer inside the anti-interference frame 12 is connected to the surrounding water, the water constraint layer inside the anti-interference frame 12 will remain calm. At this time, the flow of water at the bottom outside will not interfere with the water inside the anti-interference frame 12.

[0024] The anti-interference component includes: an anti-interference frame 12 connected to the inner surface of the mounting frame plate 11, and a sealing gasket 15 connected to the bottom of the anti-interference frame 12; wherein, fixing holes 13 are provided on both sides of the anti-interference frame 12, a locking rod 14 is installed on the surface of the anti-interference frame 12, one end of the locking rod 14 is threaded to the inner wall of the fixing hole 13, and the bottom of the sealing gasket 15 is sealed.

[0025] In addition, the sealing gasket 15 is a structure that seals the bottom of the anti-interference frame 12 to ensure that the water flow channel will not interfere with the water constraint layer of the workpiece and to ensure the stability of the internal water constraint layer. The assembly frame plate 11 limits the anti-interference frame 12 and fixes the anti-interference frame 12 by locking rod 14. At the same time, the water inlet and return structure is located at the bottom of the placement box 3 and outside the anti-interference frame 12, which can effectively reduce the interference of the water flow channel to the internal water constraint layer of the anti-interference frame 12 and further improve the stability of the water constraint layer.

[0026] The positioning assembly includes: an adjusting cylinder 7 movably mounted on the side plate 5, and a connecting screw 9 connected to the inner wall of the adjusting cylinder 7; wherein, the surface of the side plate 5 is provided with a limiting groove 6, and the end of the adjusting cylinder 7 is provided with a limiting stop plate 8. The surface of the limiting stop plate 8 is rotatably connected to the inner wall of the limiting groove 6, and the end of the connecting screw 9 is connected to a workpiece positioning plate 10, the bottom of which is movably connected to the top of the workpiece carrier plate 4.

[0027] The adjusting cylinder 7 is a structure that drives and adjusts the connecting screw 9, enabling the workpiece positioning plate 10 to position the workpiece on the workpiece carrier plate 4. The limiting plate 8 is a structure that works with the limiting slot 6 to limit the position of the adjusting cylinder 7. Through the positioning component, the adjusting cylinder and the connecting screw are designed to work together, and the limiting plate can rotate flexibly in the slot, which facilitates the adjustment of the workpiece positioning plate, adapts to workpieces of different sizes, and effectively ensures the stability of the workpiece during the laser shock strengthening process.

[0028] The water tank, circulating water pump, water level detector and controller module of the circulating supply component realize the automatic replenishment and recycling of the water constraint layer. The water level detector monitors the liquid level in real time, and the controller module intelligently adjusts the start and stop of the circulating water pump to ensure that the thickness of the water constraint layer is constant during the processing, avoids manual intervention and improves the process stability and consistency of laser shock strengthening.

[0029] The anti-interference frame, sealing gasket, and locking rod of the anti-interference component can be detachably installed on the assembly frame plate. The sealing gasket forms a sealed space, effectively isolating the external liquid flow from interfering with the water constraint layer in contact with the workpiece, ensuring the uniformity of laser impact and the surface strengthening effect of the workpiece. In addition, the detachable structure of the anti-interference frame can facilitate subsequent cleaning, maintenance, or replacement.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
