Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment of shot blasting machines in the aviation industry, in particular to a planetary driven turntable device applied to shot blasting machines in the aviation industry. Background Art

[0002] In industrial production fields like automobiles, aircraft, and ships, shot peening equipment (shot peening machines) is often used to perform a shot peening process on corresponding parts. This process uses high-speed ejection of sand and iron shots to impact the workpiece surface, thereby improving the part's mechanical properties and changing its surface condition. Due to factors such as the equipment being processed, the material of the equipment (for example, due to changes in the processed parts), and different processing techniques, shot peening equipment uses different shot materials for different equipment components, ranging from cast iron shots, ceramic shots, to sand shots, and the outer diameters of these different shot materials can also vary.

[0003] In the prior art, when shot peening is performed on the surface of aircraft engine blades, etc., due to the large outer diameter of the blades, etc., an electric rotary worktable is generally selected to support the blades, etc., and then during the processing, the electric rotary worktable drives the blades to rotate, so that the surfaces of the upper ends of the blades can effectively pass through the nozzles at the lower end of the shot peening equipment and be shot peened. Although the existing electric rotary worktable meets the work needs to a certain extent, it only has one rotating support station, that is, when working, only after the previous corresponding part is processed, shut down and removed from the worktable, can another part be placed on it and turned on for processing; the above working method has relatively low work efficiency and increases production costs. In summary, it is particularly necessary to provide a turntable device that can be used in conjunction with shot peening equipment to improve work efficiency. Utility Model Content

When the main servo motor drive mechanism drives the multiple rotating support seats to pass through the nozzle at the lower end of the shot blasting equipment in sequence, the slave servo motor drive mechanism can drive the parts located under the nozzle to rotate. Since several parts can be processed continuously in sequence, the work efficiency is correspondingly improved and the production cost is saved.

[0007] Furthermore, the upper end of the limiting column and the lower end of the supporting plate are spaced apart.

The weight of the counterweight 64 is consistent with the weight of the servo motor reduction mechanism 61.

The workflow of the new model is as follows: (1): The staff place multiple blades that need to be shot blasted on the rotating tables 52 of the six sets of rotating support seats at the side end of the equipment (the six rotating rotating support seats pass through the side end of the staff respectively). (2): The PLC controls the main servo motor mechanism 1 to drive the support plate 3 to rotate a certain angle, and the connecting plate 53 of one of the rotating support seats and the lifting plate 65 of the lifting rotating device are in a vertical plane. (3): The PLC controls the air inlet and outlet electromagnetic valve at the lower end of the cylinder 63 to be energized and work for a period of time, and the piston cylinder of the cylinder 63 pushes the servo motor reduction mechanism 61 to move up a certain height and stop (at the same time, the PLC controls the servo motor reduction mechanism 61 to be energized and work for a period of time; the air at the upper end of the cylinder barrel is discharged through another air inlet and outlet electromagnetic valve at the upper end of the cylinder barrel). After the servo motor reduction mechanism 61 pushes the lifting plate 65 up to a certain position, the upper ends of the three rotating connecting columns 651 are respectively inserted into the three transmission holes 531 of the connecting plate of one of the rotating support seats, and one of the blades on the rotating platform of one of the rotating support seats rotates. In this way, the upper surfaces of the blades can effectively pass through the nozzle at the lower end of the shot peening equipment and be shot peened. (4): The PLC controls the air inlet and outlet electromagnetic valve at the upper end of the cylinder 63 to be energized and work for a period of time. The piston of the cylinder 63 pushes the servo motor reduction mechanism 61 to descend a certain height and stop (the air at the lower end of the cylinder is discharged through another air inlet and outlet electromagnetic valve at the lower end of the cylinder). After the servo motor reduction mechanism 61 drives the lifting plate 65 to descend to a certain position, the upper end of the three rotating connecting columns 651 and the three transmission holes 531 of the connecting plate of one of the rotating support seats are separated, and the rotating table of one of the rotating support seats stops rotating. In this way, the shot peening of each surface of the upper end of the blade is completed. (5): The PLC controls the main servo motor mechanism 1 to drive the support plate 3 to rotate a certain angle. The connecting plate 53 of the left end of one of the rotating support seats will be in a vertical plane with the lifting plate 65 of the lifting rotating device. Then, as in the above steps (3)-(5), the nozzle at the lower end of the shot peening device will shot peen the blade on the left end of one of the rotating support seats. The above processes (2)-(6) are continuously circulated, and the present invention can continuously perform shot peening on the blades that continuously pass under the nozzle. Since a number of parts can be processed continuously in sequence, the work efficiency is correspondingly improved and the production cost is saved. It should be noted that the multi-channel power output terminal of the PLC controls the working time of the electrical equipment including the motor reduction mechanism and the solenoid valve respectively. This is an extremely mature technology. This application does not elaborate on its working principle, nor does it provide any protection for the above technical solution. This application protects the structure and technical solution that can continuously perform shot peening on parts and improve work efficiency.
