They are widely used in shipbuilding, aerospace, automobiles and other fields. They are a widely used heat-resistant alloy. Usually, the heat-resistant temperature of aluminum-iron alloys can reach above 250°C.

[0003] In the surface treatment process of iron-aluminum alloy workpieces, shot peening can not only significantly improve the surface integrity and smoothness of the workpiece, but also enhance the fatigue resistance of the workpiece, improve the resistance to stress corrosion, and optimize the surface residual stress distribution. By improving the surface quality, enhancing the resistance to fatigue and stress corrosion, etc., it provides a strong guarantee for the stable service of iron-aluminum alloy workpieces in complex environments.

[0004] A shot peening machine is a device used to blast the surface of a workpiece, cleaning, strengthening, or changing the physical and chemical properties of the workpiece surface by ejecting high-speed projectiles. Existing shot peening machines typically use dual-station or multi-station shot peening to improve efficiency. For example, the shot peening machine disclosed in Chinese Utility Model Patent 201922446951.2 and the multi-station shot peening machine self-spinning device disclosed in Chinese Utility Model Patent 202222359368.X both utilize a turntable-type multi-station shot peening machine to improve shot peening efficiency.

The intermediate shaft 13 extends downward from the bottom surface of the shell 1. The provision of the intermediate shaft 13 can make the shell 1 more stably arranged above the turntable 2; in this way, when the turntable 2 rotates, the shell 1 remains stationary because it is fixedly connected to the base 2.

[0030] A shot blasting bin is formed between the shell 1 and the upper surface of the turntable 2 to prevent the balls from overflowing during the shot blasting operation. A shot blasting gun 11 is fixedly provided in the shot blasting bin, and the shot blasting gun 11 is penetrated through the top of the shell 1; the shot blasting gun 11 can be fixed on the shell 1, and the shot blasting gun 11 can also be lifted on the shell 1. There is no restriction on the setting mode of the shot blasting gun 11, nor on the setting position of the shot blasting gun 11. The shot blasting gun 11 can operate normally on the workpiece.

[0031] Of course, in response to environmental protection requirements, a dust collector can be connected above the shell 1 to remove dust from the shot blasting chamber.

[0032] The upper surface of the turntable 2 is set as a filter net 21, and the filter net 21 is provided with leakage holes through which the balls can pass. The bottom of the turntable 2 is set as a funnel-shaped shot collecting plate 22; in the shot blasting bin, the balls after the shot blasting gun 11 operates on the workpiece will leak from the filter net 21 to the shot collecting plate 22, and be discharged after being concentrated in the funnel-shaped shot collecting plate 22; the shot collecting plate 22 can be set to be separate from the turntable 2, and the two are fixedly connected by bolts.

[0033] When the turntable 2 is in a rotating state, the pill collecting plate 22 needs to store the pills; when the turntable 2 stops rotating, the pills are discharged from the bottom of the pill collecting plate 22 so that the pills can be recycled; based on this, an inclined pill collecting channel 221 is provided at the bottom of the pill collecting plate 22, and a pill outlet 222 is provided at the lowest point of the pill collecting channel 221, and the pill outlet 222 can be opened and closed; when the turntable 2 stops rotating, the pill outlet 222 is opened to discharge the pills.

[0034] A rotating shaft 26 is provided on the turntable 2, and the rotating shaft 26 is fixedly connected to the filter 21 and the pill collecting plate 22 respectively. The rotating shaft 26 continues to extend downward from the bottom of the pill collecting plate 22 and is connected to the bearing of the base 3, so that the turntable 2 can be rotatably arranged on the base 3; a flange can be provided at the central axis position of the pill collecting plate 22 to be fixedly connected to the flange correspondingly provided on the rotating shaft 26; the bottom end of the rotating shaft 26 is connected to the motor and the reduction gear box to drive the rotating shaft 26 to rotate, so as to further drive the turntable 2 to rotate.

[0035] It is worth mentioning that the lower end of the side wall of the pill collecting plate 22 can be connected to the base 3 through a bearing. The lower end of the side wall of the pill collecting plate 22 extends downward for a certain distance. A supporting ring 31 is correspondingly provided on the inner wall of the base 3, and the bearing is provided on the supporting ring 31.

[0036] On the mesh 21, storage trays 23 are evenly spaced along the circumference of the turntable 2, with each tray 23 positioned at equal distances from the central axis of the turntable 2. The trays 23 are also provided with holes through which the meatballs can pass. The rotating shafts of the trays 23 extend through the mesh 21, which is correspondingly provided with a bearing seat 211. A workpiece motor 24 is fixedly mounted on the lower surface of the mesh 21 to drive the rotation of the trays 23. The workpiece motor 24 is also connected to a reduction gearbox, which is connected to the rotating shaft of the tray 23. A sealing housing 25 is fixedly mounted on the lower surface of the mesh 21. The sealing housing 25 is sleeved around the workpiece motor 24 and fixedly connected to the bearing seat 211. The sealing housing 25 isolates the workpiece motor 24 from the meatballs in the inner cavity of the turntable 2, preventing damage to the motor.

[0037] After the turntable 2 of the device rotates around its own axis by a certain angle, the workpiece on the placement tray 23 can be within the shot peening range of the shot peening gun 11. The placement tray 23 rotates itself, so that the workpiece is evenly shot peened; the sieve 21 and the pill collecting tray 22 on the turntable 2 of the device can effectively collect the pills for recycling and reuse.

[0039] In one embodiment of the present application, preferably, a lifting cylinder 14 is fixedly provided at the central axis of the shell 1 to drive the lifting plate 12 to move up and down. The lifting plate 12 is passed through the top panel of the shell 1, and the top ends of multiple lifting plates 12 are connected to the output end of the lifting cylinder 14. In this way, one lifting cylinder 14 can drive multiple lifting plates 12 to move up and down.

[0040] In one embodiment of the present application, preferably, a sliding groove that can be embedded in the lifting plate 12 is provided on the shell 1, and the sliding groove is provided at both left and right ends of the lifting plate 12 to limit the lifting and lowering of the lifting plate 12.
