Description

Technical Field

[0001] The present application relates to the technical field of shot peening equipment, and in particular to a multifunctional hanging cage for shot peening of annular parts. Background Art

[0002] Shot peening is a technology used to significantly reduce the fatigue of parts and extend their service life. Its working principle is to spray a high-speed stream of projectiles onto the surface of the part to cause plastic deformation of the surface of the part. This deformation then forms a strengthening layer with a certain thickness, which will produce high residual stress inside the layer. The existence of this residual stress, especially the compressive stress on the surface of the part, enables the part to offset part of the stress when it is under load, thereby significantly enhancing its fatigue strength. Therefore, shot peening has become one of the important methods to improve the performance of parts.

[0003] When shot peening parts, especially ring-shaped parts such as gears, it is usually necessary to place multiple ring-shaped parts on a cage. The cage is equipped with multiple hooks for hanging ring-shaped parts, so that the parts in each position receive the same degree of reinforcement. However, if it is necessary to process ring-shaped parts of different models, it is necessary to ensure that the spacing between the parts is increased to prevent the parts from blocking each other. When it is necessary to process smaller parts, the number of parts installed on the cage is limited, and the shot peening efficiency is low. Utility Model Content

[0004] In order to improve the shot peening efficiency of annular parts, the present application provides a multifunctional hanging cage for shot peening of annular parts.

[0005] The present application provides a multifunctional hanging cage for ring-shaped shot peening, which adopts the following technical solution:

[0006] A multifunctional hanging cage for shot peening of annular parts comprises an upper fixed plate and a lower fixed plate connected by a pull rod, a lifting ring for lifting is installed above the upper fixed plate away from the lower fixed plate, a plurality of hanging parts are detachably installed along the circumferential direction between the upper fixed plate and the lower fixed plate, and a plurality of hooks for hanging annular parts are arranged on the hanging parts.

[0007] By adopting the above technical solution, hooks are set so that the annular parts can be hung on the hanging parts, and by increasing or decreasing the hanging parts and adjusting the distance between adjacent hanging parts, when the size of the annular parts is small, more annular parts can be hung on the hanging cage, thereby improving the shot peening efficiency of the annular parts.

[0008] Preferably, the hanging component also includes a center rod, and a plurality of hooks are fixedly mounted on the center rod; the upper fixed plate and the lower fixed plate are correspondingly provided with a plurality of mounting holes along their respective circumferential directions, and the center rod is slidably matched with the mounting holes.

[0009] By adopting the above technical solution and utilizing the slidingly matched center rod and the mounting hole, the hanging member can be detachably connected to the hanging cage through a relatively simple structure.

[0010] Preferably, the plurality of hooks are equally divided into a plurality of groups, the plurality of hooks in each group are evenly arranged and wound around the central rod, and the plurality of groups of hooks are equidistantly distributed along the length direction of the central rod.

[0011] By adopting the above technical solution, when the annular parts are mounted on the hanger, it can be ensured as much as possible that multiple annular parts will not overlap and affect the quality of shot peening.

[0012] Preferably, the hooks in adjacent groups are staggered.

[0013] By adopting the above technical solution, the number of mountable annular parts can be further increased, which is beneficial to further improve the shot peening efficiency.

[0014] Preferably, a limiting rod is provided on the central rod, and the limiting rod is used to abut against the upper part of the lower fixed plate close to the upper fixed plate.

[0015] By adopting the above technical solution, the position of the center rod can be limited by the limit rod to prevent the center rod from falling from the hanging cage.

[0016] Preferably, a reinforcing rod is provided between the limiting rod and the central rod.

[0017] By adopting the above technical solution, the strength of the limiting rod is improved by arranging the reinforcing rod.

[0018] Preferably, a positioning rod is provided below the lower fixed plate away from the upper fixed plate.

[0019] By adopting the above technical solution and connecting the positioning rod to the bottom of the shot blasting bin or other fixed surface, the hanging cage can be kept as stable as possible during the shot blasting process.

[0020] Preferably, a plurality of through holes are provided on the upper fixing plate and the lower fixing plate.

[0021] By adopting the above technical solution, the use of multiple through holes is not only conducive to the reuse of projectiles, but also can reduce the weight of the upper fixed plate and the lower fixed plate.

[0022] To summarize, the present application includes at least one of the following beneficial technical effects: by utilizing a plurality of slidingly matched mounting holes and hanging parts, the detachable installation of the hanging parts is realized, so that based on the shot peening processing requirements of different sizes of annular parts, relevant personnel can flexibly increase or decrease the number of installed hanging parts and adjust the distance between adjacent hanging parts, so as to enable as many annular parts as possible to be mounted on the hanging cage, thereby improving the shot peening processing efficiency of the annular parts.

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] The embodiment of the present application discloses a multifunctional hanging cage for shot peening of annular parts.

[0029] Reference Figure 1 and Figure 2 A multifunctional hanging cage for shot peening of annular parts includes an upper fixed plate 1 and a lower fixed plate 2, and the upper fixed plate 1 and the lower fixed plate 2 are connected by a plurality of pull rods 3. The hanging cage also includes a plurality of hanging parts 4, and a plurality of annular parts can be hung on the hanging parts 4. The upper fixed plate 1 and the lower fixed plate 2 are provided with a plurality of mounting holes 5 correspondingly along their own circumferential directions, and the two ends of the hanging parts 4 are slidingly connected to the mounting holes 5, so that the plurality of hanging parts 4 can be detachably installed between the upper fixed plate 1 and the lower fixed plate 2. By increasing or decreasing the number of installed hanging parts 4, and adjusting the distance between adjacent installed hanging parts 4, the processing requirements of annular parts of different sizes can be met. Moreover, when the number of hanging parts 4 increases, more annular parts can be placed on the hanging cage, thereby improving the processing efficiency of the annular parts.

[0030] refer to Figure 1 and Figure 2, the upper fixed disk 1 and the lower fixed disk 2 are in the shape of circular plates, the plate surfaces of the upper fixed disk 1 and the lower fixed disk 2 are parallel and the centers of the two are located on the same straight line. A lifting ring 11 is installed at the center of the upper surface of the upper fixed disk 1 away from the lower fixed disk 2, and the hanging cage can be hung through the lifting ring 11. A positioning rod 21 for connecting the shot peening bin is installed at the center of the lower surface of the lower fixed disk 2, so that the hanging cage can be in a stable state as much as possible during the shot peening process. The pull rod 3 is in the shape of a cylindrical rod as a whole, and the length direction of the pull rod 3 is perpendicular to the plate surface of the lower fixed disk 2. One end of a plurality of pull rods 3 is arranged on the lower fixed disk 2 along the circumferential direction of the lower fixed disk 2, and correspondingly, the other end of a plurality of pull rods 3 is arranged on the upper fixed disk 1 along the circumferential direction of the upper fixed disk 1, and the two ends of the pull rod 3 are connected to the fixed disk by bolts. In addition, the upper fixed plate 1 and the lower fixed plate 2 are provided with a plurality of through holes 6 correspondingly along their respective circumferential directions, so as to facilitate the passage of the projectiles and reduce the weight of the upper fixed plate 1 and the lower fixed plate 2. The plurality of mounting holes 5 are evenly provided along the circumferential directions of the upper fixed plate 1 and the lower fixed plate 2, and the plurality of mounting holes 5 are close to the edges of the upper fixed plate 1 and the lower fixed plate 2.

[0031] refer to Figure 2 and Figure 3 The hanging member 4 includes a center rod 42 and a hook 41 for hanging the ring member. The hook 41 is fixedly mounted on the center rod 42 by welding, and the center rod 42 is slidably connected to the mounting hole 5. A limit rod 43 is fixedly mounted on one end of the center rod 42 close to the lower fixed plate 2. The limit rod 43 abuts against the upper surface of the lower fixed plate 2, and the hook 41 is not mounted below the limit rod 43. The limit rod 43 is mounted on both sides of the center rod 42, and the length direction of the limit rod 43 is perpendicular to the length direction of the center rod 42. The center rod 42 can be fixed by the limit rod 43. A reinforcing rod 44 is welded between the end of the limit rod 43 away from the center rod 42 and the center rod 42, so as to strengthen the strength of the limit rod 43.

[0032] The hook 41 is L-shaped as a whole, one end of the hook 41 is welded to the center rod 42, and the other end of the hook 41 is away from the center rod 42 and arranged upward, so that the annular part can be hung on the hook 41, and the annular part can be prevented from falling during the shot peening process or the disassembly and assembly of the hanging part. Multiple hooks 41 are divided into multiple groups in equal numbers, and multiple groups of hooks 41 are arranged equidistantly along the length direction of the center rod 42, and each group of hooks 41 is arranged around the center rod 42. In this embodiment, the number of hooks 41 in each group is set to three, and the angle between adjacent hooks 41 is 120°. In addition, the hooks 41 of the upper and lower adjacent groups are staggered, so that more annular parts can be placed and folding between the annular parts can be avoided as much as possible.

[0033] Before installing the hanging parts 4, it is necessary to determine the number of hanging parts according to the size of the hanging ring parts. For example, when large-sized ring parts need to be processed, the number of hanging parts 4 installed on the hanging cage is reduced; when small-sized ring parts need to be processed, the number of hanging parts 4 installed on the hanging cage is increased. During use, the upper end of the center rod 42 is first inserted into the installation hole 5 of the upper fixed plate 1, so that the center rod 42 can be placed vertically between the upper fixed plate 1 and the lower fixed plate 2; then the lower end of the center rod 42 is inserted into the installation hole 5 of the lower fixed plate 2, and the limit rod 43 is abutted against the upper part of the lower fixed plate 2 to achieve the fixing of the hanging parts 4. After the hanging parts 4 are fixed, the relevant personnel can hang multiple ring parts on the hook 41.

[0034] The implementation principle of a multifunctional hanging cage for shot peening of annular parts in the embodiment of the present application is as follows: through a plurality of slidingly matched mounting holes 5 and hanging parts 4, the hanging parts 4 can be detachably mounted between the upper fixed plate 1 and the lower fixed plate 2; relevant personnel can appropriately increase or decrease the number of installation hanging parts 4 and adjust the distance between adjacent hanging parts 4 according to the size of the annular parts that need to be shot peened, so that the size of the annular parts will not overlap during processing, and a larger number of annular parts can be set in the hanging cage, thereby improving the processing efficiency of the annular parts.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
