Technical Field

[0001] This utility model relates to the field of surface treatment technology in machining, and in particular to a shot blasting strengthening device for diesel engine connecting rods. Background Technology

[0002] Diesel engine connecting rods are the "bridge" for power transmission. Their design and material selection are directly related to the reliability, efficiency, and lifespan of the engine, especially in applications such as ships and heavy machinery. During the operation of a diesel engine, the connecting rod, as a key component for power transmission, must withstand complex alternating stresses. Its surface properties have a significant impact on the service life and reliability of the connecting rod. Traditional surface treatment methods for diesel engine connecting rods have many shortcomings. Some methods use manual shot blasting or simple equipment, which makes it difficult to guarantee the uniformity and coverage of shot blasting. This results in inconsistent surface quality of the treated connecting rods, a high rework rate, and an inability to meet the needs of large-scale production. Therefore, this application proposes a shot blasting strengthening treatment device for diesel engine connecting rods. Utility Model Content

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1 and Figure 3 As shown, the diesel engine connecting rod shot blasting strengthening device proposed in this utility model includes a housing 1 and a shot blasting mechanism disposed inside the housing 1. The shot blasting mechanism includes a shot blasting chamber 5 fixed to the inner wall of the housing 1. Multiple fixed boxes 13 are fixedly connected to the outer wall of the shot blasting chamber 5. A shot blasting outlet 14 is fixedly connected to one end of each of the multiple fixed boxes 13, and the outer walls of the multiple shot blasting outlets 14 all penetrate the shot blasting chamber 5. The shot blasting chamber 5 fixed to the inner wall of the housing 1 is welded from high-strength wear-resistant steel plate, and the inner wall is coated with a wear-resistant layer, which has good wear resistance and impact resistance. The multiple fixed boxes 13 fixedly connected to the outer wall of the shot blasting chamber 5 are evenly distributed in a ring, providing installation space for the shot blasting transmission structure. The shot blasting outlets 14 fixedly connected to one end of the fixed boxes 13 penetrate the shot blasting chamber 5, so that the shot can be accurately sprayed onto the connecting rod surface inside the shot blasting chamber 5.

[0027] In addition, such as Figure 3 and Figure 4 As shown, the inner walls of multiple fixed boxes 13 are all equipped with shot blasting transmission structures. The shot blasting transmission mechanism includes a drive motor 16 fixed to one side of the outer wall of the fixed box 13 near the top. A rotating disk 18 is fixedly connected to the output end of the drive motor 16, and the output end of the drive motor 16 is also connected to rotating disks 18 on both sides of the bottom end via a gear set 17. Multiple rotating disks 18 are located inside rotor boxes 15, and a transmission pipe assembly 19 is fixedly connected to the top of each rotor box 15. A shot blasting port 20 is fixedly connected to the end of each rotor box 15 away from the transmission pipe assembly 19, and a shot blasting outlet 14 is fixedly connected to the end of each shot blasting port 20 away from the rotor box 15. The outer wall of the shot blasting outlet 14 is penetrated by the shot blasting chamber 5. By setting the drive motor 16 to use a high torque, low speed servo motor, the stable output of shot blasting power is ensured. The output end of the drive motor 16 is connected to the rotating disk 18 on both sides of the bottom through the gear set 17 to realize the synchronous operation of multiple rotating disks. Multiple rotating disks 18 are installed in the rotor box 15. The transmission pipe group 19 connected to the top of the rotor box 15 is used to transport shot to the rotating disk 18. The rotating disk 18 is provided with specially designed blades on its edge. When the rotating disk rotates at high speed, the blades drive the shot to be ejected at high speed from the shot blasting port 20 through the shot blasting outlet 14, realizing efficient shot blasting treatment of the connecting rod surface.

[0028] And, as Figure 1 and Figure 2 As shown, clamping and fixing mechanisms are provided on both sides of the outer wall of the outer casing 1. The clamping and fixing mechanisms include two fixing blocks 8 fixed to one side of the outer wall of the outer casing 1. The ends of the two fixing blocks 8 away from the outer casing 1 are fixedly connected to telescopic rods 9. The ends of the two telescopic rods 9 away from the fixing blocks 8 are fixedly connected to connecting blocks 10. The outer walls of the two connecting blocks 10 are slidably connected to clamps 11. By setting the two fixing blocks 8 on one side of the outer wall of the outer casing 1 as the basic support of the clamping and fixing mechanism, the telescopic rods 9 are connected to the connecting blocks 10. The telescopic rods 9 are electric push rods, which can be extended and adjusted according to the length and specifications of the connecting rod. The clamps 11 slidably connected to the outer walls of the connecting blocks 10 prevent the connecting rod from sliding during shot blasting and avoid damage to the surface of the connecting rod. By adjusting the telescopic rods 9 and clamps 11, precise positioning and stable clamping of connecting rods of different specifications of diesel engines can be achieved.

[0029] It should be added that, such as Figure 1 and Figure 3 As shown, multiple baffles 6 are fixedly connected to both sides of the inner wall of the shot blasting chamber 5. A connecting rod inlet / outlet 7 is provided between the baffles 6. The baffles 6 fixedly connected to both sides of the inner wall of the shot blasting chamber 5 are arranged in a staggered pattern. Their function is to guide the trajectory of the shot and prevent it from ejecting from the ejection device. Simultaneously, the connecting rod inlet / outlet 7 between the baffles 6 is designed according to the specifications of common diesel engine connecting rods to ensure that the connecting rod can smoothly enter and exit the shot blasting chamber 5. A receiving plate 3 is fixedly connected to the other side of the outer wall of the outer shell 1, and two support legs 4 are fixedly connected to the bottom of the outer shell 1. A connecting plate 3 is fixedly connected to the top of the outer shell 1. The shot blasting chamber 5 is equipped with a top feed inlet 2 and a receiving plate 3 located at the bottom of the shot blasting chamber 5. The bottom of the inner wall of the shot blasting chamber 5 is provided with a shot blasting recovery port 12, which is located between multiple shot blasting outlets 14. The top feed inlet 2 at the top of the outer shell 1 is designed in a funnel shape to facilitate the feeding of shot. The receiving plate 3 on the other side of the outer wall of the outer shell 1 is located at the bottom of the shot blasting chamber 5 and is used to receive the connecting rod that falls after the process is completed. The shot blasting recovery port 12 at the bottom of the inner wall of the shot blasting chamber 5 is connected to the external shot recovery chamber. Shots scattered during the shot blasting process can be collected through the recovery port.

[0030] The above specific embodiments are merely several optional embodiments of this utility model.
