[0002] The suspension device of the shot blasting machine is an important part of the shot blasting machine. It is mainly used to fix and suspend the workpieces that need to be shot blasted. It usually consists of a hook, a sling, a bracket, a rotating mechanism, connecting parts, etc.; the hook is used to directly hook the workpiece to ensure that the workpiece will not fall off during the shot blasting process. The shape and structure of the sling will be designed according to the shape and characteristics of the workpiece to achieve stable suspension.

[0003] After retrieval, the Chinese patent publication number is CN208961809U, and the literature disclosed by this patent is as follows: A suspension device for a shot blasting machine, belonging to the technical field of shot blasting machines, specifically including that a middle frame is installed at the bottom of the top frame, and a bottom frame is installed at the bottom of the middle frame. The top frame, the middle frame and the bottom frame are all regular hexagonal columnar frame structures. Support columns are arranged in the middle of the top frame, the middle frame and the bottom frame. A hook is fixed at the top of the top frame. A plurality of dividing rods are arranged on the six surfaces of the top frame, the middle frame and the bottom frame. A gap for placing barbell plates is formed between adjacent dividing rods. The structure of the utility model is simple and is suitable for shot blasting operation of barbell plates, and the surface treatment is more comprehensive.

[0004] In the process of using the prior art, because the workpiece cannot rotate, the workpiece may cause uneven distribution of shot during the shot blasting process. In some areas of the shot, the shot is dense, while in other areas, the shot is scarce, which will lead to uneven cleaning quality, affect the overall quality stability of the product, and cause waste of shot. In view of this, we propose a portable suspension device for a shot blasting machine. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a portable suspension device for a shot blasting machine, which solves the problem of the decline in the cleaning quality of the workpiece caused by the inability of the workpiece to rotate.

A ball is fixedly connected to the top end of the second rotating rod. The top end of the second rotating rod is slidably connected with a second annular groove through the ball. The bottom end of the second rotating rod is rotatably connected to the top of the frame. A sun gear is arranged inside the planet gear. The planet gear meshes with the sun gear. A first rotating rod is fixedly connected to the inner side of the sun gear. The top end of the first rotating rod is rotatably connected to the bottom of the top plate through a bearing.

[0007] Preferably, a vibration structure is arranged at the bottom end of the first rotating rod. The vibration structure includes a housing. A telescopic rod is movably connected to the inner wall of the housing. A collision ball is fixedly connected to the other end of the telescopic rod. An inclined block is fixedly connected to the inner wall of the frame. The collision ball is arranged in cooperation with the inclined block.

[0008] Preferably, the number of the inclined blocks is six. The inclined surfaces of the six inclined blocks are arc-shaped. The collision ball abuts against the inclined surfaces of the inclined blocks. By setting the collision ball to slide slowly on the inclined block to a high position and then move quickly, the appropriate vibration of the frame by the collision ball can make the action of the projectiles on the surface of the workpiece more uniform and delicate, thus helping to obtain a more ideal surface roughness.

[0009] Preferably, the number of the planet gears is six. The six planet gears are symmetrically arranged respectively. The number of the frames and the inclined blocks are both six. The six inclined blocks are symmetrically arranged respectively.

[0010] Preferably, a first annular groove is formed in the top of the base. A limiting frame is slidably connected in the first annular groove. The top end of the limiting frame is fixedly connected to the bottom of the toothed ring. The limiting frame is in a "U" shape. By setting the limiting frame to slide in the first annular groove, the frame can be limited, making the frame more stable during rotation.

[0011] Preferably, the number of the frames is six. The six frames are all arc-shaped. A plurality of strip-shaped holes are formed in the surface of the frame. The strip-shaped holes are symmetrically arranged at equal intervals. The plurality of formed strip-shaped holes are used for hanging workpieces.

[0012] Preferably, a spring is provided inside the housing. One end of the spring is fixedly connected to the inner wall of the housing, and the other end of the spring is fixedly connected to one end of the telescopic rod. Through the elastic potential energy of the spring, the collision ball reciprocally collides inside the frame to achieve the vibration of the frame. The vibration helps to avoid the accumulation of shot in certain areas on the surface of the workpiece; the vibration of the workpiece increases the collision chance with the shot, shortens the cleaning time, and improves the working efficiency of the shot blasting machine.

[0013] As can be seen from the above technical solutions, a portable suspension device for a shot blasting machine provided by an embodiment of this specification has at least the following beneficial effects:

A ball is fixedly connected to the top end of the second rotating rod 407. The top end of the second rotating rod 407 is slidably connected with the second annular groove 8 through the ball. The bottom end of the second rotating rod 407 is rotatably connected to the top of the frame 7. A sun gear 405 is arranged inside the planetary gear 406. The planetary gear 406 meshes with the sun gear 405. A first rotating rod 404 is fixedly connected to the inner side of the sun gear 405.

A limiting frame 3 is slidably connected in the first annular groove 2. The top end of the limiting frame 3 is fixedly connected to the bottom of the toothed ring 403. The limiting frame 3 is in a "U" shape. By arranging the limiting frame 3 to slide in the first annular groove 2, the frame 7 can be limited, making the frame 7 more stable during rotation. The number of frames 7 is six. All six frames 7 are arc-shaped. A number of strip-shaped holes are opened on the surface of the frame 7. The strip-shaped holes are symmetrically arranged at equal intervals. The opened strip-shaped holes serve to hang workpieces.

[0026] Furthermore, through the rotation structure 4 provided, the planetary gear 406 makes a circular motion inside the tooth ring 403, and then the frame 7 makes a circular motion following the second rotating rod 407, causing the workpiece to be cleaned to continuously change its position and angle during the shot peening process, ensuring that all its surfaces can be evenly impacted by the shot, thereby more thoroughly removing the scale, rust, and attachments on the surface and improving the effect and quality of the shot peening treatment.

[0027] Embodiment 2

[0028] Please refer to Figures 1 - 4 As shown, a vibration structure 5 is provided at the bottom end of the first rotating rod 404. The vibration structure 5 includes a housing 501. The inner wall of the housing 501 is movably connected with a telescopic rod 502. The other end of the telescopic rod 502 is fixedly connected with a collision ball 503. The inner wall of the frame 7 is fixedly connected with an inclined block 504. The collision ball 503 is arranged in cooperation with the inclined block 504. The number of the inclined blocks 504 is six. The inclined surfaces of the six inclined blocks 504 are arc-shaped. The collision ball 503 abuts against the inclined surface of the inclined block 504. By setting the collision ball 503 to slowly slide on the inclined block 504 to a high position and then move quickly, the appropriate vibration of the frame 7 by the collision ball 503 can make the action of the shot on the workpiece surface more uniform and delicate, thereby helping to obtain a more ideal surface roughness. The number of the planetary gears 406 is six, and the six planetary gears 406 are symmetrically arranged respectively. The numbers of the frame 7 and the inclined block 504 are six respectively, and the six inclined blocks 504 are symmetrically arranged respectively. A spring is arranged inside the housing 501. One end of the spring is fixedly connected with the inner wall of the housing 501, and the other end of the spring is fixedly connected with one end of the telescopic rod 502. Through the elastic potential energy of the spring, the collision ball 503 reciprocally collides inside the frame 7 to realize the vibration of the frame 7. The vibration helps to avoid the accumulation of shot in certain areas on the workpiece surface; the vibration of the workpiece increases the collision chance with the shot, shortens the cleaning time, and improves the working efficiency of the shot peening machine.

[0029] Furthermore, through the vibration structure 5 provided, during the rotation of the frame 7, the collision ball 503 reciprocally collides inside the frame 7 to realize the vibration of the frame 7. The vibration helps to avoid the accumulation of shot in certain areas on the workpiece surface; the vibration of the workpiece increases the collision chance with the shot, shortens the cleaning time, and improves the working efficiency of the shot peening machine.

[0030] When the portable suspension device for a shot blasting machine of the present utility model is in use, by starting the motor 401, the output shaft of the motor 401 drives the driving gear 402 to rotate. Through the meshing of the driving gear 402 and the gear ring 403, the driving gear 402 drives the gear ring 403 to rotate. Through the rotation of the gear ring 403, the planetary gear 406 and the sun gear 405 are driven to rotate. The planetary gear 406 moves around the outer ring of the sun gear 405. By rotating the frame 7, the workpiece to be cleaned can continuously change its position and angle during the shot blasting process, ensuring that each of its surfaces can be evenly impacted by the shot, thereby more thoroughly removing the scale, rust, and attachments on the surface, improving the cleaning quality. By setting the collision ball 503 to roll on the inclined surface of the inclined block 504, as the collision ball 503 slides to the top on the inclined surface of the inclined block 504, the collision ball 503 moves inside the outer shell 501 through the telescopic rod 502, using the telescopic rod 502 to compress the spring. When the collision ball 503 leaves the highest inclined surface of the inclined block 504, the elastic potential energy of the spring is released. Subsequently, the collision ball 503 collides inside the frame 7, and the frame 7 can be vibrated. The vibration helps to avoid the accumulation of shot in certain areas on the surface of the workpiece; the vibration of the workpiece increases the collision chance with the shot, shortens the cleaning time, and improves the working efficiency of the shot blasting machine; appropriate vibration can make the action of the shot on the surface of the workpiece more uniform and delicate, thus helping to obtain a more ideal surface roughness.
