In order to achieve the above object, the basic scheme of the present utility model is as follows: the utility model provides an automatic disc changer for automatic grinding and polishing machine, includes base, rotation seat, storage frame, two electronic slide rails and two disc change shift fork assemblies, it connects on the base to rotate the seat, the storage frame is fixed on the base, just the storage frame is located and rotates the seat side, two electronic slide rail is installed on the base surface, and two electronic slide rail is located respectively and rotates seat and storage frame side, two the direction of motion of electronic slide rail is relative, two the disc change shift fork assemblies are installed respectively on electronic slide rail and are driven its relative movement by electronic slide rail, the disc change shift fork assemblies includes slider, support and shift fork, the slider is installed on electronic slide rail, the support is fixed on the slider, the shift fork is close to on the support the shift fork bottom surface height of rotating the seat is higher than and rotates the seat up end height, just the distance of shift fork bottom surface distance rotation seat up end does not surpass and throws a disc thickness.

The basic scheme has the beneficial effects that: the storage rack can be used for placing a plurality of spare polishing discs, when polishing, the storage rack can automatically lift, after the polishing discs with required mesh number are aligned to the rotating seat, the shifting fork on the right side slides leftwards to push the polishing discs on the storage rack to the rotating seat on the left side, then the polishing driving motor is started to polish a sample, after the preset polishing time is reached, the polishing driving motor is closed, and the shifting fork on the left side slides rightwards to push the polishing discs on the rotating seat back to the storage rack. And then the storage rack continues to lift until the next grinding and polishing disc with the required mesh is aligned with the rotating seat, and the shifting fork on the right side continues to push the grinding and polishing disc to the left on the rotating seat.

Further, the base is hollow structure, the rotation seat includes rolling disc, pivot, negative pressure fan, grinds and throws driving motor and belt pulley subassembly, the rolling disc is fixed in the pivot, just rolling disc and pivot are hollow structure, the rolling disc up end is equipped with a plurality of negative pressure holes with the inside cavity intercommunication of rolling disc, the pivot passes through the bearing and rotates to be connected at the base up end, the pivot bottom is equipped with the negative pressure connecting hole, negative pressure fan sealing rotation connects in negative pressure connecting hole department, the pivot passes through belt pulley subassembly and grinds and throws driving motor and be connected. After the grinding and polishing disc on the storage rack is pushed to the left rotating seat by the shifting fork on the right side, the negative pressure fan is opened, the interior of the rotating disc is pumped, negative pressure is generated at the negative pressure hole, and the grinding and polishing disc can be well adsorbed on the rotating disc.

Further, the storage frame includes fixing base, frame, chain, sprocket, a plurality of rack, storage driving motor and belt pulley unit, the frame is fixed on the fixing base, be equipped with the rectangle spout in the frame, a plurality of rack sliding connection is in the rectangle spout, and a plurality of the rack is fixed with the chain, the chain wiring is on the sprocket, the sprocket passes through belt pulley unit and is connected with storage driving motor. The chain wheel rotates to drive the chain to rotate, so that the placing frame is driven to move along the rectangular sliding groove, and finally the polishing disc on the storage frame moves up and down, so that the polishing disc with the required mesh number is aligned with the rotating disc.

Further, the shifting fork is an arc-shaped shifting fork with radian matched with the grinding and polishing disc. The arc-shaped shifting fork can be attached to the edge of the grinding and polishing disc, so that the grinding and polishing disc can be prevented from being inclined to two sides in the process of pushing the grinding and polishing disc, and the grinding and polishing disc can be prevented from being centered on the rotating seat.

Further, the bottom surface of the shifting fork close to the storage rack is lower than the upper end surface of the rotating disc. The shifting fork close to the storage rack can be blocked by the rotating disk after pushing the grinding and polishing disk to be placed on the rotating disk, so that the grinding and polishing disk is not pushed to move.

Further, the diameter of the rotating disc is equal to the diameter of the polishing disc. When the shifting fork is limited by the rotating disc to stop moving, the polishing disc is just completely placed on the rotating disc and is centered with the rotating disc by matching with the height of the shifting fork.

Further, the distance between the rotating disc and the storage rack is smaller than the radius of the polishing disc. When the shifting fork pushes the grinding and polishing disc to move between the rotating disc and the storage frame, the grinding and polishing disc cannot fall off due to the fact that the gravity center of the grinding and polishing disc exceeds the rotating disc or the storage frame.
