[0002] Shot blasting is an important surface treatment process for automotive parts. It mainly involves high-speed jetting of metal shot to impact the surface of the workpiece, utilizing its impact and cleaning action to achieve the purpose of strengthening, cleaning, and pretreatment. Shot blasting can effectively remove impurities such as oxide scale, rust, and welding slag from the surface of parts, while forming a uniform compressive stress layer on the surface, improving the fatigue strength and corrosion resistance of the parts. This process is widely used in the manufacturing and repair of key components such as engines, chassis, and transmissions.

[0003] Currently, shot blasting of automotive parts mostly uses traditional hangers to fix the workpieces. Traditional hangers are designed individually according to the shape and size of the automotive parts, and different workpieces are equipped with different models of hangers. They are then fed into the shot blasting machine for processing via a conveyor line.

[0004] However, existing hangers have a simple structure and poor versatility, making it difficult to adapt to workpieces of different shapes and sizes. This results in long production preparation cycles, high usage costs, and problems such as unstable workpiece fixation and uneven stress.

[0005] To address the above problems, this utility model proposes a multi-functional hanger for shot blasting of automotive parts. Utility Model Content

[0028] See Figure 1 , Figure 3 and Figure 4 The shot-blasted workpiece includes material 9. A multi-functional hanger for shot blasting of automotive parts includes a bracket assembly 1 and a first suspension bracket 2, a second suspension bracket 3, a third suspension bracket 4, a first limiting bracket 5, and a second limiting bracket 6 sequentially arranged on the bracket assembly 1. Both ends of the first suspension bracket 2, the second suspension bracket 3, the third suspension bracket 4, the first limiting bracket 5, and the second limiting bracket 6 are provided with a snap-fit ​​groove 7 and a positioning groove 8. The support assembly 1 provides support and guidance, and provides installation conditions for the first suspension frame 2, the second suspension frame 3, the third suspension frame 4, the first limiting frame 5, and the second limiting frame 6 set on the support assembly 1, ensuring that each component maintains stable positioning during shot blasting. The first suspension frame 2, the second suspension frame 3, and the third suspension frame 4 select appropriate methods to suspend the top of the material 9 according to different sizes and shapes. The first limiting frame 5 and the second limiting frame 6 select restrictive methods according to the size and shape of the bottom of different materials 9, so as to achieve all-round fixation of the workpiece material 9 during shot blasting and prevent it from falling off due to vibration or impact.

[0029] See Figure 2 The bracket assembly 1 includes a connecting rod 14. A fixing rod 12 is symmetrically installed on one side of the connecting rod 14, and an mounting rod 15 is symmetrically installed on the other side of the connecting rod 14. A suspension plate 11 is installed on both fixing rods 12. Multiple sets of positioning 16 are equidistantly arranged on the two mounting rods 15. The first suspension frame 2, the second suspension frame 3, the third suspension frame 4, the first limit frame 5, and the second limit frame 6 are snapped onto the mounting rod 15 and the positioning 16 through the snap-fit ​​groove 7 and the positioning groove 8.

[0030] The connecting rod 14 provides a fixed position for the fixed rod 12 and the mounting rod 15, supporting the overall structure. The two fixed rods 12 are symmetrically arranged to enhance structural stability and ensure that the hanger does not deform when subjected to the impact of the workpiece material 9 and shot blasting. The suspension plates 11 installed on the fixed rods 12 are used to connect with external hoisting equipment to realize the overall lifting and movement of the hanger. The external hoisting equipment is a transmission line. Therefore, when the transmission line passes through the through holes on the two suspension plates 11, the two suspension plates 11 can stably suspend the hanger on the transmission line, ensuring that it does not shift or fall off during operation. The two suspension plates 11 have a Z-shaped structure, so that the transmission line is constrained by the Z-shaped structure when passing through the through holes. The mounting rod 15 provides an installation position for the positioning 16. Mounting rods 15 are fixed at both ends of connecting rod 14. Multiple positioning rods 16 are equidistantly distributed on mounting rods 15 to adjust the installation spacing of the first suspension frame 2, second suspension frame 3, third suspension frame 4, first limit frame 5, and second limit frame 6, adapting to the suspension requirements of workpieces 9 of different lengths and improving the versatility of the hanger. At the same time, mounting rods 15 and positioning rods 16 cooperate through snap-fit ​​grooves 7 and positioning grooves 8 to achieve quick snap-fit ​​positioning of the first suspension frame 2, second suspension frame 3, third suspension frame 4, first limit frame 5, and second limit frame 6, achieving firm installation and convenient disassembly, adapting to the high-efficiency operation requirements in mass production. The structural design of the hanger improves lightweight while strengthening the fixing structure, reducing material consumption while bearing the weight of the workpiece.

[0031] A guide plate 13 is connected between the two fixed rods 12. The guide plate 13 is used to provide guidance and fixation when entering the shot blasting chamber, so as to avoid the hanger shaking due to airflow impact or mechanical vibration during shot blasting, which would affect the processing accuracy.

[0032] The first suspension frame 2 includes a first suspension support plate 21. Multiple sets of first positioning rods 22 and second positioning rods 23 are installed on one side of the first suspension support plate 21. The first positioning rods 22 and second positioning rods 23 are adapted to each other. The first suspension support plate 21 provides installation positions for the first positioning rods 22 and second positioning rods 23. The first positioning rods 22 and second positioning rods 23 cooperate to clamp and position the top of the material 9. The multiple sets of first positioning rods 22 and second positioning rods 23 are equidistantly distributed along the length of the first suspension support plate 21. The clamping position can be adjusted according to the shape of the workpiece. The clamping ends of the first positioning rods 22 and second positioning rods 23 have a Z-shaped structure, first inward and then outward. When clamping the narrower part of the top of the material 9, it can be clamped through the rectangle formed inside the first positioning rods 22 and second positioning rods 23. When clamping the wider part of the top of the material 9, the limiting surface formed by the Z-shaped outer side of the first positioning rods 22 and second positioning rods 23 can achieve stable clamping and prevent slippage. The second suspension frame 3 includes a second suspension support plate 31, and second mounting rods 32 are equidistantly installed on one side of the second suspension support plate 31. Each of the second mounting rods 32 is equipped with a hanging rod 33.

[0033] The second suspension support plate 31 provides a fixed position for the second mounting rod 32, which facilitates the adjustment of the height of the hanging rod 33. The hanging rod 33 is fixed on the second mounting rod 32 and is used to support the middle area of ​​the material 9. The second mounting rod 32 is a long strip structure. The hanging rod 33 is fixed near the material 9 for easy support. When there is a through hole or a supporting part in the middle of the material 9, the hanging rod 33 can be inserted into the through hole or abut against the supporting part. It works with the first suspension frame 2 to achieve multi-point support for the material 9 and prevent the workpiece from deforming or shifting during shot blasting. The third suspension frame 4 includes a third suspension support plate 41, and a plurality of support rods 42 are installed on one side of the third suspension support plate 41.

[0034] The third suspension support plate 41 provides an installation reference surface for the support rod 42. The support rod 42 is fixed on the third suspension support plate 41. When some materials 9 have grooves or stepped structures inside, the support rod 42 abuts against them to achieve positioning and support of the inner wall of the workpiece and prevent displacement during processing.

[0035] The first limiting frame 5 includes a first limiting support plate 51. A plurality of first limiting grooves 52 are provided on one side of the first limiting support plate 51, and a plurality of protective rods 53 are installed on the other side of the first limiting support plate 51.

[0036] The first limiting support plate 51 provides an installation reference for the first limiting groove 52. The first limiting groove 52 is equidistantly distributed along the side of the first limiting support plate 51. The first limiting groove 52 and the first limiting support plate 51 cooperate to limit the movement of the material 9, ensuring that the workpiece remains stable during shot blasting and avoiding positional deviation due to vibration. If the shape of the material 9 protrudes towards the protective rod 53, the protective rod 53 forms a two-sided limit on the protruding part.

[0037] The second limiting frame 6 includes a second limiting support plate 61. A second limiting groove 62 is provided on one side of the second limiting support plate 61, and a plurality of third limiting grooves 63 are provided on the other side of the second limiting support plate 61. A guide rod 64 is fixed on the second limiting groove 62.

[0038] See Figure 5 and Figure 6 The second limiting support plate 61 provides an installation reference for the second limiting groove 62 and the third limiting groove 63. The third limiting groove 63 limits the bottom of the material 9. If the bottom of the material 9 still has a tendency to swing after being limited by the protective rod 53, the second limiting groove 62 laterally constrains the outer edge of the bottom of the material 9 and works in conjunction with the protective rod 53 to further suppress the shaking of the workpiece.

[0039] Material 9 includes workpiece 1 91 and workpiece 2 92, which are two different workpieces.

[0040] By symmetrically installing mounting rods 15 on one side of the connecting rod 14, and symmetrically providing multiple sets of positioning 16 on the mounting rods 15, the mounting rods 15 and positioning 16 are used in conjunction with the first suspension frame 2, the second suspension frame 3, the third suspension frame 4, the first limit frame 5, and the second limit frame 6. Through the snap-fit ​​grooves 7 and positioning grooves 8 on the first suspension frame 2, the second suspension frame 3, the third suspension frame 4, the first limit frame 5, and the second limit frame 6, the mounting rods 15 and positioning 16 at different positions are snapped together, and different materials 9 are fixed and limited, achieving the effect of quick clamping and positioning of various workpieces and improving the stability of shot blasting.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
