The top surface of the conversion platform 51 is located above the two electric push rods 53 and is installed with a storage platform 55. The two fixing pieces 54 are fixedly installed on one side of the bottom surface of the storage platform 55 respectively;

[0020] The workpiece to be sandblasted is placed on the storage table 55 of the conversion assembly 5 located outside the sandblasting room 2. After the placement is completed, the protective door 22 is opened. After the protective door 22 is opened, the motor 4 is started, and the conversion assembly 5 is driven to operate by controlling the rotating shaft 41 through the output end of the motor 4. The conversion table 51 of the conversion assembly 5 is controlled to rotate 180 degrees, and the workpiece placed on the storage table 55 is sent into the sandblasting room 2. (This automatic sandblasting device 3 is an existing sandblasting device. The workpiece to be sandblasted is sandblasted by the spraying mechanism and the feeding mechanism in conjunction with the nozzle. The nozzle can be moved up and down, front and back, left and right by the driving device to achieve all-round sandblasting of the workpiece). After being sent into the sandblasting room 2, the electric push rod 53 at the bottom of the corresponding storage table 55 in the sandblasting room 2 is opened. The electric push rod 53 cooperates with the fixing part 54 to control the storage table 55 to slide, and the workpiece placed on the storage table 55 is sent to the bottom of the automatic sandblasting device 3 for sandblasting. During sandblasting, the protective door 22 is in a closed state. When the workpiece in the sandblasting chamber 2 is sandblasted, the next workpiece that needs to be sandblasted is placed on another storage table 55 in advance for standby. After the workpiece in the sandblasting chamber 2 is sandblasted, it can be directly sent into the sandblasting chamber 2 for sandblasting. With the cooperation of the motor 4 and the conversion component 5, the loading of the workpiece that needs to be sandblasted is completed, which solves the problem that the loading and unloading process of the workpiece is relatively cumbersome, time-consuming and labor-intensive when the existing automatic sandblasting machine is working, and the process of taking and placing the workpiece takes a lot of time, resulting in the sandblasting device being unable to work, affecting the workpiece processing efficiency.
