[0034] First, the parts to be ground are clamped by the clamp 2, the grinding wheel 52 is installed, and there is a gap between the bottom of the installed grinding wheel 52 and the top of the receiving plate 9 to avoid friction between the grinding wheel 52 and the receiving plate 9 during rotation. The two-dimensional control platform 3 precisely controls the movement of the moving seat 4 in the horizontal direction, the grinding machine 5 and the moving plate 91 move together with the moving seat 4, and the two-dimensional control platform 3 controls the movement of the moving seat 4 to return to the initial position, and then controls the movement of the moving seat 4, the grinding machine 5 and the moving plate 91 to the right. Control the grinding machine 5 to loosen the grinding wheel 52, then control the electric push rod one 6 to drive the push plate 7 to move to the right, drive the receiving plate 9, the grinding wheel 52 and the moving plate 91 to move to the right, make the grinding wheel 52 separate from the center shaft 51, and the limiting rotating rod 92 is blocked in front of the grinding wheel 52 to avoid the grinding wheel 52 from rolling down. When the push rod 95 is clamped into the hook-shaped part 912 of the moving plate 91, control the electric push rod two 90 to drive the moving plate 91 to move forward, the blocking part 911 of the moving plate 91 no longer blocks the limiting rotating rod 92, and the limiting rotating rod 92 rotates to the horizontal state under the action of gravity through the guidance of the arc-shaped guide hole 94. The limiting rotating rod 92 no longer limits the grinding wheel 52, the moving plate 91 pulls the push rod 95 together to move forward, the push rod 95 can push the grinding wheel 52 to roll forward and enter the fixed frame 10 through the strip-shaped slot 101. At the same time, the convex block part 913 contacts the sliding block 125, the convex block part 913 extrudes the sliding block 125 through the curved surface of the sliding block 125 to make the convex block part 913 pass through the sliding block 125, and the moving plate 91 moving forward will push the extrusion plate 114 to move forward, the extrusion plate 114 extrudes the inclined surface 115 to make the sliding seat 111 move to the left, the sliding seat 111 drives the connecting frame 112 and the electric clamp plate 113 to move to the left, and controls the electric clamp plate 113 to clamp the grinding wheel 52 entering the fixed frame 10. Then control the electric push rod two 90 to drive the moving plate 91 to move backward, the moving plate 91 drives the push rod 95 to move backward and reset, the blocking part 911 drives the limiting rotating rod 92 to rotate upward and reset, the convex block part 913 will drive the sliding block 125 to move backward, drive the extrusion block 124 together to move backward, the extrusion block 124 extrudes the grinding wheel 52 on the leftmost side of the conveying belt 122 through the extrusion surface to move to the left. Because the right side of the limiting plate 8 is inclined, the new grinding wheel 52 extrudes the limiting plate 8 to move downward, when the new grinding wheel 52 passes through the limiting plate 8 and enters the placing slot 81, the limiting plate 8 rises to reset through the action of the compression spring. At this time, the limiting rotating rod 92 blocks the front of the grinding wheel 52, the limiting plate 8 limits the grinding wheel 52, and the grinding wheel 52 stays on the receiving plate 9. The groove on the top of the receiving plate 9 can increase the friction between the grinding wheel 52 and the receiving plate 9, so that the grinding wheel 52 will not roll randomly during replacement. At the same time, because the moving plate 91 moves backward, the extrusion plate 114 moves backward and resets through the reset spring, the extrusion plate 114 no longer extrudes the inclined surface 115, the sliding seat 111 moves to the right and resets through the reset spring,The sliding seat 111 drives the connecting frame 112, the electric clamping plate 113, and the clamped old grinding wheel 52 to move to the right. The old grinding wheel 52 is squeezed by the inclined surface 115 of the limiting block 110 and retracts. When the old grinding wheel 52 passes the limiting block 110, the limiting block 110 is reset by the return spring. The limiting block 110 can limit the old grinding wheel 52 on the collection column 11. The electric clamping plate 113 then releases the grinding wheel 52, thereby collecting the old grinding wheel 52 on the collection column 11. Then, the electric push rod 6 drives the push plate 7 to move to the left relative to the moving seat 4 to reset, driving the limiting plate 8 and the receiving plate 9 to move to the left together, so that the new grinding wheel 52 on the receiving plate 9 is fitted onto the central shaft 51 for installation. The new grinding wheel 52 can then be used to perform precision machining on the parts. In this way, there is no need to manually remove the old grinding wheel 52 and install the new grinding wheel 52. The grinding wheel 52 can be automatically replaced, with a high degree of automation and high work efficiency. ,

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
