Description

Technical Field

[0001] The utility model belongs to the technical field of flywheel production, and particularly relates to a shot blasting frame of a casting shot blasting machine. Background Art

[0002] A flywheel is a commonly used component in automobiles and engines, which is a metal disc with teeth on the edge fixed at one end of the crankshaft. Currently, during flywheel production, shot blasting treatment is required for the flywheel. Shot blasting treatment is a surface strengthening process for castings, that is, using pellets (sand) to bombard the surface of the casting and implant residual compressive stress, improving the fatigue strength of the casting, improving the surface roughness of the part, and enhancing the physical properties. During the shot blasting treatment process, a shot blasting frame is an essential tool. However, the existing flywheel shot blasting frames still have the following problems:

[0003] First, the shot blasting frame is provided with hooks at certain intervals according to the height of the flywheel workpiece. Due to the height limitation of the shot blasting machine, the number of hooks provided on the shot blasting frame is limited, and the number of flywheels that can be placed at one time is limited. The number of flywheels treated by shot blasting each time is small, resulting in low work efficiency.

[0004] Second, the hanging frame of the shot blasting frame is generally fixedly arranged, and the height of the hanging parts is fixed. When hanging parts of different heights, flexible adjustment cannot be performed.

[0005] Third, when hanging workpieces of different sizes, since the distance between two hooks is fixed and the hooks are fixed by welding, it is not convenient to hang wider workpieces, thus reducing the practicality of the hanging frame. Summary of the Invention

[0006] The purpose of the utility model is to provide a shot blasting frame for a casting shot blasting machine, which has a simple structure, increases the number of shot blasted workpieces, and expands the scope of application, aiming at the deficiencies of the existing technology.

[0007] The purpose of the utility model is achieved by adopting the following technical solutions:

[0008] A shot blasting frame for a casting shot blasting machine includes a shot blasting frame body. The shot blasting frame body includes a column, several hooks, and multiple layers of hanging rings. A base is provided at the lower end of the column, and a lifting ring is provided at the upper end of the column. Fixed round platforms are arranged on the column at certain intervals, and hanging rod assemblies are provided on each fixed round platform. Each hanging rod assembly is provided with at least two hanging rods. One end of each hanging rod is horizontally connected to the fixed round platform, and the hanging rods of adjacent two hanging rod assemblies are staggered; one hanging ring is arranged between every two adjacent hanging rod assemblies, and the hanging ring is fixedly connected to the other end of the hanging rod. Hook mounting rings are provided on both the hanging ring and the hanging rod, and the hooks are movably arranged in the hook mounting rings.

[0009] Further, it further includes universal wheels, and the universal wheels are provided on the lower end surface of the base.

[0010] Further, the base adopts a disc structure, and a plurality of counterweight ribs are provided on the disc.

[0011] Further, the hook is in an S-shaped structure.

[0012] Further, the hanging rod assembly is provided with six hanging rods.

[0013] Further, the two adjacent hanging rod assemblies are respectively a second hanging rod assembly and a first hanging rod assembly for connecting the hanging ring. The first hanging rod assembly for connecting the hanging ring is horizontally fixed on the fixing table of the column, and the hanging rods of the second hanging rod assembly are movably arranged on the fixing table of the column through a clamping device.

[0014] Further, the clamping device adopts a fastening bolt. A bolt hole and a hanging rod mounting groove are provided on the fixing round table for mounting the second hanging rod assembly. The hanging rod of the second hanging rod assembly is provided with a flat head for connecting with the fixing round table, and the fastening bolt is used to press against the flat head of the hanging rod.

[0015] Adopting the above technical solutions has the following beneficial effects:

[0016] The structure of the utility model is simple and is composed of a column, a hanging ring and multiple layers of hanging rings. The column is provided with fixing round tables at intervals. Hanging rod assemblies are provided on the fixing round tables. Each hanging rod assembly is composed of a plurality of hanging rods, and the hanging rods of two adjacent hanging rod assemblies are arranged in a staggered manner. A hanging ring is arranged between two adjacent hanging rod assemblies. Hook mounting rings are provided on both the hanging ring and the hanging rod, increasing the hooks for the components to be processed. The staggered hanging rods are used to place the parts to be shot peened so that the parts to be shot peened do not block each other, ensuring that the parts can be evenly shot peened, improving the shot peening effect of the shot peening machine on the parts, increasing the number of shot peening, and improving the working efficiency. The hook is movably arranged in the hook mounting ring, which is convenient for taking and placing the hook according to the size of the casting to be processed and flexibly adjusting the position of the hook.

[0017] The universal wheels are added. In addition to hoisting and moving, it is convenient for the shot peening rack to move on the ground, increasing the flexibility of operation.

[0018] The two adjacent hanging rod assemblies are respectively a second hanging rod assembly and a first hanging rod assembly for connecting the hanging ring. The first hanging rod assembly for connecting the hanging ring is horizontally fixed on the fixing table of the column, and the hanging rods of the second hanging rod assembly are movably arranged on the fixing table of the column through a clamping device. For parts to be shot peened with different heights, the hanging rod assemblies on the vertical rods can be disassembled, expanding the scope of use.
