[0041] In use, the worker will put the castings needed to be polished between the fixed blocks 275, and the clamping mechanism 27 clamps and fixes the castings: the worker starts the motor 274, the motor 274 drives the bidirectional screw rod 272 to rotate, the threaded block 273 threaded on the bidirectional screw rod 272 drives the fixed blocks 275 to move close to each other, until the fixed blocks 275 contact with the castings, the castings cannot fall off from the fixed blocks 275, so as to complete the clamping and fixing of the castings. At this time, the power of the polishing mechanism 12 is started, and the polishing mechanism 12 polishes one side of the castings. After polishing, the worker starts the electric push rod 24, the output shaft of the electric push rod 24 is elongated, the electric push rod 24 drives the rack 25 to slide to the right, the gear 23 meshed at the top of the rack 25 drives the fixed frame 26 to rotate counterclockwise by one hundred and eighty degrees through the rotating shaft 22, the fixed frame 26 drives the clamped castings to turn over, so as to facilitate the other side of the polishing mechanism 12 to polish the other side of the castings, without the need to release the fixing of the castings in the middle, thereby increasing the efficiency of the castings polishing. After the castings are polished on both sides, the motor 274 is controlled to rotate in the opposite direction, so that the fixed blocks 275 move away from each other. At this time, the polished castings can be taken down, and the polishing of a single casting is completed. When the threaded block 273 drives the fixed blocks 275 to move, the telescopic shell 4 fixedly connected to the outer side wall of the threaded block 273 telescopes correspondingly. When the threaded blocks 273 move close to each other, the telescopic shell 4 between the threaded blocks 273 contracts, and the remaining telescopic shells 4 stretch. Similarly, when the threaded blocks 273 move away from each other, the telescopic shell 4 between the threaded blocks 273 stretches, and the remaining telescopic shells 4 contract. The telescopic shell 4 shields the cavity 271 without affecting the normal activity of the threaded block 273, so as to avoid the splashing of debris into the cavity 271 during polishing, thereby affecting the normal activity effect of the bidirectional screw rod 272 and the threaded block 273.

[0042] The above-mentioned polishing mechanism 12 is a prior art, specifically a mechanical arm polishing. The polishing mechanism 12 adopts advanced sensor technology, which can realize real-time sensing of the shape and position of the workpiece. Through the built-in control system, the mechanical arm can operate autonomously according to the preset machining path and force, realizing precise polishing effect. The mechanical arm can also intelligently adjust according to real-time data to ensure the stability of the machining quality. As long as the polishing of the castings can be realized, the specific structure is not described here.

[0043] Embodiment two

[0044] According to the basis of embodiment one, an auxiliary function is added.

[0045] Reference Figures 1-4The bottom of the rack 25 is fixedly connected with a dovetail block 251, the top of the polishing table 11 is provided with a dovetail groove 252, and the dovetail block 251 is slidably connected in the dovetail groove 252. The opposite surface of the fixed block 275 is provided with a protective pad 276. The top of the polishing table 11 is provided with a protective frame 3, the protective frame 3 is sleeved outside the gear 23 and the rack 25, and the output shaft of the electric push rod 24 and the rotating shaft 22 penetrate the protective frame 3.

[0046] When the electric push rod 24 controls the rack 25 to move, the rack 25 drives the bottom dovetail block 251 to slide in the dovetail groove 252, the dovetail block 251 guides the movement of the rack 25, and the stability of the rack 25 during movement is increased, so that the turnover of the casting is conveniently and quickly realized. When the fixed block 275 clamps the casting, the protective pad 276 is in contact with the surface of the casting, the protective pad 276 can be made of rubber, on the premise of increasing the friction between the fixed block 275 and the casting, the damage of the fixed block 275 to the surface of the casting is avoided, so as to affect the quality of the finished casting product. The protective frame 3 shields the gear 23 and the rack 25 when the polishing mechanism 12 polishes, so as to avoid that the debris falls into the gear 23, the electric push rod 24 and the dovetail groove 252, thereby affecting the normal turnover effect of the casting.
