[0022] The beneficial effects of the present invention:

[0023] (1) The cover body of the circuit breaker hydraulic disc spring operating mechanism is automatically conveyed to the lower part of the clamping and feeding mechanism by a belt conveyor. Subsequently, the clamping and feeding mechanism stably and automatically clamps and fixes the cover body. Then, the driving mechanism drives the installation pipe, installation plate, and installation disc to flip, realizing the automatic feeding of the cover body.

[0024] (2) By driving the socket mechanism to adjust the grinding blocks on the outer grinding ring and inner grinding ring, the positions of the grinding blocks are adjusted according to the diameters of different diameter edges and corners on the cover body. At the same time, the grinding blocks on the outer grinding ring and inner grinding ring are driven to move up and down. Then, by driving the clamped cover body to rotate, the grinding and deburring of cover bodies of different sizes and circular edges and corners with different diameters on the cover body are realized, greatly improving the grinding effect and grinding efficiency of the cover body.

[0025] (3) At the same time, when the grinding blocks are severely worn, move the fixed iron blocks on the grinding blocks, remove the fixed iron blocks on the grinding blocks from the installation slots, then insert the fixed iron blocks on the new grinding blocks into the installation slots, and then the permanent magnet blocks in the installation slots adsorb the fixed iron blocks to fix the fixed iron blocks and grinding blocks in the installation slots, thus realizing the portable replacement of the grinding blocks. With the arc-shaped setting of the grinding blocks, the grinding blocks reciprocate up and down to grind and deburr the circular edges and corners of the cover body, and at the same time grind the edges and corners into rounded corners, further improving the grinding effect of the cover body.

[0026] (4) During the grinding process, the vacuum cleaner works. The vacuum cleaner sucks air through the connecting pipe to the installation pipe, and then the installation pipe sucks air through the pipeline to the dust suction ring. The dust suction ring sucks the grinding debris into the vacuum cleaner through multiple dust suction holes, realizing the automatic cleaning of the grinding debris. Description of the Drawings

[0064] The working principle of the present invention: The lid body 71 is conveyed below the mounting frame. Subsequently, the first electro-hydraulic rod 11 drives the mounting box 12 and the feeding pipe 13 to move downward, so that the feeding pipe 13 enters the hole in the middle position of the lid body 71. Then, the second electro-hydraulic rod 14 drives the transmission plate 15 to move. The transmission plate 15 drives the transmission column 16 to move. The transmission column 16 drives the first fixing plate 17 to move. At the same time, the transmission column 16 drives the first transmission inclined block 18 and the third transmission inclined block 191 to move upward. The first transmission inclined block 18 drives the second transmission inclined block 19 to move outside the feeding pipe 13.

The inclination angle of the inclined surface of the first transmission inclined block 18 with respect to the horizontal plane is greater than the inclination angle of the third transmission inclined block 191 with respect to the horizontal plane. When the distances that the transmission column 16 drives the first transmission inclined block 18 and the second transmission inclined block 19 to move upward are the same, the distance that the first transmission inclined block 18 drives the second transmission inclined block 19 to move is less than the distance that the third transmission inclined block 191 drives the fourth transmission inclined block 192. When the second transmission inclined block 19 drives a plurality of clamping blocks 190 to internally fix the hole of the lid body 71, at this time, the second fixing plate 193 supports inside the lid body 71. During this moving process, the first electro-hydraulic rod 11 drives the mounting box 12 and the feeding pipe 13 to move upward. At the same time, the transmission column 16 drives the first fixing plate 17 to clamp and fix the top of the lid body 71, thereby realizing the stable clamping and fixing and automatic loading and unloading of lid bodies 71 of different sizes, facilitating subsequent deburring of the lid bodies 71.

[0065] After the lid body 71 is stably clamped and fixed, the driving mechanism drives the mounting pipe 2 to rotate at this time, so as to drive the clamped lid body 71 to turn upwards. Then, the third electro-hydraulic rod 31 drives the outer grinding ring 32 to move up and down, and the fourth electro-hydraulic rod 33 drives the inner grinding ring 34 to move up and down. At the same time, according to the diameter of the edges and corners of the lid body 71, the adjusting structure drives the mounting column 35 to move. The mounting column 35 drives the connecting plate 36 to move, and the connecting plate 36 drives the connecting plate 36 to move. The connecting plate 36 drives the telescopic rod 37 and the grinding block 390 to move, so that the grinding block 390 fits the edges and corners of the inner and outer surfaces of the lid body 71. At the same time, during the grinding process, the telescopic rod 37 and the spring 39 cooperate to perform telescopic buffering on the grinding block 390. At the same time, the first transmission mechanism drives the feeding pipe 13 to rotate, and the feeding pipe 13 drives the clamped and fixed lid body 71 to rotate, so that the grinding block 390 grinds the burrs on the circular edges and corners of the inner and outer surfaces of the lid body 71. At the same time, during the grinding process, the first electro-hydraulic rod 11 drives the mounting box 12 and the feeding pipe 13 to move up and down reciprocally. At the same time, in cooperation with the arc-shaped setting of the grinding block 390, the grinding block 390 performs reciprocating grinding and deburring on the circular edges and corners of the lid body 71, and at the same time grinds the edges and corners into rounded corners, further improving the grinding effect on the lid body 71, so as to realize the grinding and deburring of lid bodies 71 of different sizes and circular edges and corners of different diameters on the lid body 71, greatly improving the grinding effect and grinding efficiency of the lid body 71.
