[0056] In this embodiment, as a further optimized solution, please refer to Figure 6 An electromagnet 25 is provided in the inner cavity of the slot 23, and the guide block is made of a metal material that can be magnetically adsorbed, such as iron.

[0057] Working principle:

[0058] First, the porcelain insulator to be processed is placed on the top of the processing platform 2 (with the head of the porcelain insulator facing upwards), and after it is placed in the middle of a plurality of positioning fixtures 3, the positioning fixtures 3 are controlled to work to fix the porcelain insulator (the specific process of the positioning fixture 3 working is that the electric telescopic rod drives the pressing plate to move and contact the side wall of the porcelain insulator, clamping it, and thus fixing it);

[0059] Second, the fixing assembly 64 of the telescopic member 6 works to release the restriction on the moving rod 62, and then pushes the spring 63 to expand and push the moving rod 62 to move to the side away from the sleeve 61, so that the mounting frame 10 brings the turntable 7 closer to the porcelain insulator (at this time, the cleaning member 12 on the turntable 7 is facing the porcelain insulator), and the movement of the mounting frame 10 will bring the walking assembly 18 to move, so that it first slides on the top wall of the processing platform 2, and as the mounting frame 10 continues to move, the walking assembly 18 will move to the inclined surface of the top of the porcelain insulator and slide, so as to guide the mounting frame 10 to rise along the inclination of the top wall of the porcelain insulator when it approaches the porcelain insulator, until the cleaning member 12 fits with the side wall of the head of the porcelain insulator;

[0060] Third, the cleaning member 12 moves closer to the turntable 7 and pushes the moving push block 14 to squeeze the flexible connecting member 21, move the limiting member 26 out of the limiting groove, and release the restriction on the mounting frame 17. Under the action of the elastic member 19, the mounting frame 17 moves closer to the frame 5 with the walking assembly 18 and presses the pressure sensor 22.

[0061] Fourth, after receiving the information that the pressure sensor 22 is under pressure, the control device 29 controls the fixing component 64 to work, fixes the moving rod 62, and controls the air pump 283 of the locking component 28 to inflate the air bag 282 to expand it and contact the inner wall of the slide groove, thereby fixing the slider 281 in the slide groove, thereby fixing the height of the telescopic member 6;

[0062] Fifth, the control device 29 controls the driving device to work, drives the processing platform 2 to rotate, and makes the head of the porcelain insulator rotate and contact the cleaning member 12, which is used to clean the head of the porcelain insulator (the cleaning time is preset). After the cleaning is completed, the control device 29 controls the driving member 11 to work, so that the turntable 7 rotates, and the glue spraying head 16 faces the head of the porcelain insulator, and then controls the pump of the glue storage component 9 to work, and the adhesive inside the storage tank is sprayed onto the head of the rotating porcelain insulator through the glue spraying head 16 (the glue spraying time is preset). After the glue spraying is completed, the control device 29 controls the glue storage component 9 to stop working, and controls the driving component 11 to work, so that the turntable 7 rotates again. After the sandblasting head 13 is facing the head of the porcelain insulator, the control device 29 controls the valve of the sand supply component 8 to open, so that the sand inside the hopper is sprayed onto the head of the rotating porcelain insulator through the sandblasting head 13 (the sandblasting time is pre-set). After the sandblasting is completed, the control device 29 controls the valve to close, and controls the driving device to stop working, and removes the porcelain insulator from the processing platform 2 for subsequent processing.

[0063] It should be noted that when the turntable 7 rotates so that the glue spray head 16 and the sandblasting head 13 are facing the head of the porcelain insulator, there is a distance between the glue spray head 16 and the head of the porcelain insulator, and between the sandblasting head 13 and the head of the porcelain insulator, and the distance can be adjusted according to the initial installation position of the glue spray head 16 and the sandblasting head 13.

[0064] It should also be noted that after completing a sanding process, the driving member 11 will drive the turntable 7 to rotate in the opposite direction and reset, and will also reset the mounting frame 17. During the resetting process, the moving block contacts the inclined surface of the limit member 26, pushing the limit member 26 upward, so that the moving block moves to the bottom of the limit member 26. Under the action of the elastic element 27, the limit member 26 is inserted into the limit groove to fix the mounting frame 17 again; the above-mentioned processed porcelain insulators refer to porcelain parts.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
