[0002] Shot peening is a surface treatment technology that uses high-speed shot to impact the surface of the workpiece to achieve the purpose of cleaning, strengthening or changing the surface morphology. As an important surface treatment technology, shot peening is widely used in aerospace, automobile manufacturing, machinery manufacturing and other fields.

[0003] However, in traditional technology, the position of the spray gun inside the shot blasting room is relatively fixed, which has the defect of insufficient flexibility. When the workpiece has a complex shape or large size changes, the fixed-position spray gun may not be able to fully cover all areas that need shot blasting, resulting in uneven shot blasting effect or omissions, and the distance of the spray gun cannot be dynamically adjusted according to the real-time position of the workpiece, which limits the flexibility and adaptability of the shot blasting. On the other hand, for production lines that need to frequently replace workpieces or where the position of the workpiece changes frequently, the fixed-position spray gun requires manual or mechanical assistance to reposition, which increases production preparation time and labor costs, and has poor use effect.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-7As shown, in this embodiment, the shot blasting room cabin is equipped with a front spray gun moving mechanism 1, a rear spray gun moving mechanism 2 and a top spray gun moving mechanism 3. The front spray gun moving mechanism 1, the rear spray gun moving mechanism 2 and the top spray gun moving mechanism 3 all include a PLC controller, a driving member 16, a moving assembly, a mounting plate 5 and at least two spray guns 4. The spray guns 4 are mounted on the mounting plate 5, and the mounting plate 5 is mounted on the moving assembly. The driving member 16 is connected to the moving assembly, and the driving member 16 drives the moving assembly to move, so that the moving assembly drives the mounting assembly The plate 5 and the spray gun 4 are moved. According to the position requirements of the workpiece processing hole, each spray gun 4 can be selectively opened by PLC control according to the process requirements. It also includes a fixed frame 17 arranged below the moving component. The moving component includes a movable moving plate 11 arranged on the fixed frame 17. The driving member 16 is mounted on the end face of the moving plate 11, and the output shaft of the driving member 16 is connected to the fixed frame 17. The output shaft of the driving member 16 is extended to push or pull the moving plate 11 to move. The moving component also includes a fixed sleeve 10 and a moving rod 9. The moving rod 9 is connected to the fixed frame 17. The fixed sleeve 10 is mounted on the surface of the mobile plate 11 and moves therewith. The mounting plate 5 is mounted on the front end of the mobile rod 9 and is locked therewith by bolts. The driving member 16 is a cylinder. The driving member 16 drives the mobile plate 11 to move, so that the mobile rod 9 drives the mounting plate 5 and the spray gun 4 to move together. The moving assembly also includes a linear slide 13 and a linear slider 18. The linear slide 13 is mounted on the surface of the fixed frame 17. The linear slider 18 is mounted on the bottom of the mobile plate 11 and slides with the linear slide 13. The outer side of the linear slide 13 is equipped with a dustproof The dust cover assembly includes a first dust cover 14 provided on the left and right sides of the linear slide 13 and a second dust cover 12 provided in the middle of the linear slide 13, and a connecting plate 15 is provided between the first dust cover 14 and the second dust cover 12. The design of the first dust cover 14 and the second dust cover 12 can effectively prevent external impurities such as dust, oil stains, and iron filings from entering the interior of the slide. Through the isolation effect of the first dust cover 14 and the second dust cover 12, the linear slide 13 can be kept clean, reducing the performance degradation of the linear slide 13 caused by the accumulation of impurities;

[0026] At least two workpiece limit blocks 7 are installed on the end face of the mounting plate 5 in the front spray gun moving mechanism 1. The front end portion of the workpiece limit block 7 is inclined from the inside to the outside to form an inclined surface 6. The workpiece limit block 7 is equipped with a positioning wheel group 8. The positioning wheel group 8 includes three positioning wheels rotatably connected to the workpiece limit block 7, and the positioning wheels are arranged in sequence along the inclined surface 6 of the workpiece limit block 7. The positioning wheel closest to the starting end of the inclination angle is called the head end positioning wheel. The head end positioning wheel serves as the first contact point or support point, which ensures the initial positioning and stability of the workpiece when sliding or moving. The second positioning wheel arranged in the direction of gradually increasing inclination angle The positioning wheel is called the intermediate positioning wheel. The intermediate positioning wheel not only further stabilizes the movement trajectory of the workpiece, but also adjusts the balance and force distribution during the movement through its position. The positioning wheel located at the highest end of the inclination angle is called the end positioning wheel. As the final contact point or support point, it ensures the stability and accuracy of the workpiece when it reaches the maximum inclination angle. Therefore, the three positioning wheels are arranged in sequence from low to high along the inclination angle of the inner end face of the limit block, and work together to ensure the stability, smoothness and accuracy of the workpiece during movement. The shape and number of the workpiece limit block 7 and the positioning wheels are adaptively adjusted according to the shape of the workpiece.

[0027] Working principle: The workpiece is sent into the cabin of the shot blasting room through the roller conveyor system. Once the workpiece reaches the designated position, the conveying system stops working to ensure that the workpiece remains stationary during the shot blasting process. The cylinder serves as the power source, and the positioning of the workpiece is accurately controlled by the telescopic movement of the cylinder, ensuring that the workpiece can be stably and accurately placed in the predetermined position before the shot blasting operation. The front spray gun moving mechanism 1, the rear spray gun moving mechanism 2 and the top spray gun moving mechanism 3 use the moving assembly as a moving guide to ensure that the spray gun 4 moves smoothly and accurately in the horizontal and vertical directions. It is driven by the cylinder, and by controlling the extension and contraction of the cylinder, the spray gun 4 can be aimed at the holes to be shot blasted on the workpiece. When the shot blasting of all holes is completed, the cylinder moves again to drive the spray gun 4 back to its initial position to avoid interference with the workpiece or the conveying system. Subsequently, the roller conveying system is restarted to smoothly convey the workpiece that has completed the shot blasting to the next workstation.

[0028] Compared with traditional technology: the spray gun 4 is mounted on the mounting plate 5, and the mounting plate 5 is further mounted on the moving assembly, and the moving assembly is driven by the driving member 16 to move, so that the spray gun 4 can move accordingly. When performing shot blasting, the mobility of the spray gun 4 enables it to be dynamically adjusted according to the shape, size and position of the workpiece, thereby achieving comprehensive coverage and uniform treatment of the surface of complex workpieces. It has strong flexibility, can effectively improve the adaptability and efficiency of the spraying operation, and can ensure the uniformity and consistency of the spraying, reduce omissions and overlaps in the spraying process, and help improve the spraying quality and the appearance quality of the product.
