[0030] The fixing device is applied to a saw blade sand blasting machine. The driving mechanism in the saw blade sand blasting machine can drive the rotating disc 1 to rotate. When the driving mechanism drives the rotating disc 1 to rotate and moves one clamping and fixing assembly 4 to the outside of the saw blade sand blasting machine, the lifting piece 7 is moved into the lifting piece at the lower end of the lifting driving mechanism of the saw blade sand blasting machine. At this time, the other clamping and fixing assemblies 4 are located in the saw blade sand blasting machine. The lifting driving mechanism of the saw blade sand blasting machine is started to drive the lifting piece to move upward and drive the lifting piece 7 to move upward. The upward movement of the lifting piece 7 drives the clamping and fixing assembly 4 to move upward (i.e., the upward movement of the top plate 42, the sliding rod 44, the bottom plate 43, the connecting rod 9 and the fixed seat 41). Then, the saw blade is placed on the top of the lower clamping piece, the upper clamping piece is placed on the top of the saw blade, and then the lower clamping piece, the saw blade and the upper clamping piece are placed on the saw blade seat 3. Then, the lifting driving mechanism of the saw blade sand blasting machine drives the clamping and fixing assembly 4 to move downward, drives the fixed seat 41 to move downward and press the upper clamping piece 5, and makes the upper clamping piece 5 press the saw blade tightly to fix the saw blade. Then, the driving mechanism in the saw blade sand blasting machine drives the rotating disc 1 to rotate, so that the clamping and fixing assembly 4 moves to the inside of the saw blade sand blasting machine for sand blasting treatment. At the same time, the lifting piece 7 is separated from the lifting piece at the lower end of the lifting driving mechanism. At this time, the bottom plate 43 is kept in a downward pressing state by the elastic force of the compression spring 45, so that the upper clamping piece 5 is always pressed against the saw blade to keep the saw blade fixed. When the saw blade sand blasting is finished, the driving mechanism drives the rotating disc 1 to rotate, so that the clamping and fixing assembly 4 moves to the outside of the saw blade sand blasting machine. Then, the lifting driving mechanism of the saw blade sand blasting machine is started to drive the lifting piece to move upward and drive the lifting piece 7 to move upward. The upward movement of the lifting piece 7 drives the clamping and fixing assembly 4 to move upward. At this time, the upper clamping piece 5 is adsorbed on the bottom of the fixed seat 41 and moves upward. The sand blasted saw blade is taken away. Then, the saw blade to be sand blasted is placed on the lower clamping piece. Then, the lifting driving mechanism of the saw blade sand blasting machine drives the clamping and fixing assembly 4 to move downward, so that the upper clamping piece 5 is pressed against the saw blade. The above steps are repeated to realize continuous sand blasting treatment of the saw blade.

[0031] The above only describes some embodiments of the present application. Those skilled in the art can make some modifications and improvements without departing from the inventive concept, which are all within the protection scope of the present application.
