Description

Technical Field

[0001] This utility model belongs to the technical field of valve processing equipment, and provides a valve shot peening bracket that improves shot peening efficiency and pass rate and reduces enterprise manufacturing costs. Background Technology

[0002] Valve shot peening is a crucial and efficient surface strengthening process. By creating a residual compressive stress layer on the valve surface, it fundamentally improves the valve's resistance to fatigue fracture and stress corrosion. This is essential for ensuring the long-term stable and reliable operation of the engine under high load and high temperature conditions.

[0003] Current valve shot peening involves installing the valves into a shot peening disc, placing the disc on a rack, and then performing shot peening on the valves on the rack. Taking our company as an example, the existing rack includes a support frame, a shot peening disc mounting section on the support frame, and a suspension section at the top of the support frame. During shot peening, seven shot peening discs containing valves are placed on the rack. Due to the rack's structure, the disc surfaces are parallel to the ground, resulting in each shot peening of seven discs taking over 30 minutes, with low coverage (maximum reaching 90%), leading to a low shot peening pass rate.

[0004] In summary, the existing mounting brackets result in low efficiency and low pass rate of valve shot peening, leading to high manufacturing costs for enterprises. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a valve shot peening bracket that improves shot peening efficiency and pass rate and reduces enterprise manufacturing costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a valve shot peening bracket, including a suspension component; wherein: the lower part of the suspension component is fixedly integrated with a central support, and three sets of shot peening disc support frames are evenly distributed on the central support. The shot peening disc support frames are rotatably connected to the central support. Each shot peening disc support frame includes a vertical support column, on which three sets of shot peening disc mounting frames are fixed at equal intervals. The bottom of the shot peening disc mounting frame located at the lowest position is fixed with an integral rotating shaft a, which is rotatably connected to the lower part of the central support. The top of the vertical support column is fixed with an integral reversing drive mechanism, which includes a rotating shaft b rotatably connected to the upper part of the central support. The lower end of the rotating shaft b is fixedly connected to the top of the vertical support column, and the top of the rotating shaft b is fixed with an integral horizontal drive arm.

[0007] To facilitate the assembly between the central support and the shot peening disc support frame, the above solution further includes: the central support includes a support shaft, and three upper support beams and three lower support beams are evenly distributed at the top and bottom ends of the support shaft, respectively, and the outer ends of the upper and lower support beams are provided with through holes; The rotating shaft a is located in the through hole on the lower support beam, and the rotating shaft b is located in the through hole on the upper support beam.

[0008] To ensure the rotation of the shot peening disc support frame, the above solution further includes: a bearing assembly between the rotating shaft a and the through hole on the lower support beam, and a bearing assembly between the rotating shaft b and the through hole on the upper support beam.

[0009] To facilitate the fabrication of the shot peening disc mounting bracket, the above-mentioned scheme further includes: the shot peening disc mounting bracket includes a support plate and two support beams symmetrically fixed to the side wall of the support plate, one of the two support beams being fixed integrally with a vertical support column; Two longitudinal support beams are symmetrically fixed to the side wall of the support plate. These two longitudinal support beams are arranged to intersect with the two transverse support beams. The outer end of each longitudinal support beam is provided with a limiting vertical beam integral with it.

[0010] To further improve the shot peening coverage, in the above scheme, the supporting beam and the vertical supporting column form an angle A, which is an acute angle of 65° to 85°.

[0016] like Figures 1 to 5As shown, the valve shot peening bracket of this utility model includes a suspension component 1; wherein: the lower part of the suspension component 1 is fixedly integrated with the central support 2, and three sets of shot peening disc support frames 3 are evenly distributed on the central support 2. The shot peening disc support frames 3 are rotatably connected to the central support 2. The shot peening disc support frame 3 includes a vertical support column 301, and three sets of shot peening disc mounting frames 302 are fixedly fixed at equal intervals on the vertical support column 301. The bottom of the shot peening disc mounting frame 302 located at the lowest position is fixedly connected to a rotating shaft a303 integrated with it. The rotating shaft a303 is rotatably connected to the lower part of the central support 2. The top of the vertical support column 301 is fixedly connected to a reversing drive mechanism 304 integrated with it. The reversing drive mechanism 304 includes a rotating shaft b305 rotatably connected to the upper part of the central support 2. The lower end of the rotating shaft b305 is fixedly connected to the top of the vertical support column 301. The top of the rotating shaft b305 is fixedly connected to a horizontal drive arm 306 integrated with it. In this embodiment, the suspension component 1 can be either a hanging ring or a hook, with the hanging ring being the preferred option. The hanging ring is fixed to the top of the central support 2 by welding or threading.

[0017] To facilitate the assembly between the central support 2 and the shot peening disc support frame 3, in the above embodiment, the central support 2 further includes a support shaft 201, on which three upper support beams 202 and three lower support beams 203 are evenly distributed at the top and bottom ends, respectively, and the outer ends of the upper support beams 202 and the lower support beams 203 are provided with through holes. The rotating shaft a303 is located in the through hole on the lower support beam 203, and the rotating shaft b305 is located in the through hole on the upper support beam 202.

[0018] To ensure the rotation of the shot peening disc support frame 3, in the above embodiment, a bearing assembly is further provided between the rotating shaft a303 and the through hole on the lower support beam 203, and a bearing assembly is provided between the rotating shaft b305 and the through hole on the upper support beam 202.

[0019] To facilitate the fabrication of the shot peening disc mounting bracket 302, in the above embodiment, the shot peening disc mounting bracket 302 further includes a support plate 3021 and two support beams 3022 symmetrically fixed on the side wall of the support plate 3021. One of the two support beams 3022 is fixed as a unit with the vertical support column 301. Two supporting longitudinal beams 3023 are symmetrically fixed on the side wall of the supporting plate 3021. The two supporting longitudinal beams 3023 are arranged to cross the two supporting transverse beams 3022. The outer end of the supporting longitudinal beams 3023 is provided with a limiting vertical beam 3024 integral with it.

[0020] To further improve the shot peening coverage, in the above embodiment, an angle A is formed between the supporting beam 3021 and the vertical supporting column 301, and this angle A is an acute angle of 65° to 85°. In specific implementation, the optimal angle is 81° to 83°, but 65° or 85° is also acceptable.

[0021] All components in the above embodiments are commercially available products.

[0022] Based on actual use by our company, the structure described in the above embodiments has increased the number of processing discs from 7 to 9, reduced shot peening time from over 30 minutes to within 20 minutes, and increased shot peening coverage from 90% to 100%. The specific usage process is as follows: Workers place the shot peening disc equipped with valves on the shot peening disc support frame 3. Due to the action of the limiting vertical beam 3024, the shot peening disc with valves will not slide off the shot peening disc support frame 3. Then, it is transferred to the shot peening station via a hook connected to the suspension component 1 on the overhead crane in the workshop. The suspension component 1 is then suspended on the hook at the shot peening station. This hook is driven to rotate by a drive mechanism, and the suspension component 1 rotates together with the hook at the shot peening station, causing the discharge port of the shot peening machine and the shot peening disc equipped with valve stems to continuously change positions, effectively ensuring the shot peening coverage. A limiting rod is provided on one side of the hook at the shot peening station. Since the suspension 1 rotates together with the hook at the shot peening station, the shot peening disc support frame 3 also rotates together with the hook at the shot peening station. During the rotation, the transverse drive arm 306 is restricted by the limiting rod on one side of the hook at the shot peening station, which forces the transverse drive arm 306 to rotate the vertical support column 301 180° in the through holes at the outer ends of the upper support beam 202 and the lower support beam 203. At the same time, the transverse drive arm 306 passes around the limiting rod and resumes to rotate with the suspension 1. During this process, the shot peening disc equipped with valves on the shot peening disc mounting frame 302 changes direction and passes through the discharge port of the shot peening machine, effectively ensuring that the shot peening disc equipped with valves is 100% covered by the discharge port of the shot peening machine. Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
