[0007] A polishing layer is arranged on the outer side of the base, and a connecting rod is connected to the bottom of the base.

[0008] Preferably, guide grooves are equidistantly provided inside the base, guide rods are inserted into the guide grooves, and one end of the guide rods is connected to the polishing layer.

[0009] Preferably, a ratchet seat and an adjustment arm are provided on the upper side of the base, and two ends of the adjustment arm are hinged to the ratchet seat and the inner wall of the polishing layer through a mounting block and a pin shaft respectively.

[0010] Preferably, a pawl is rotatably mounted on the upper side of the base through a rotating column, one end of the pawl abuts against the ratchet seat, and the groove inside the base is elastically connected to the limiting column through a reset spring.

[0011] Preferably, a connecting groove is provided inside the base, the base is rotatably connected to the connecting layer via the connecting groove, and the top of the connecting layer is connected to the ratchet seat.

[0012] Preferably, an extension layer is connected to the top of the base, plug-in grooves are equidistantly provided inside the extension layer, and plug-in columns are plugged into the plug-in grooves.

[0013] Preferably, one end of the plug-in column is connected to the inner wall of the polishing layer on an adjacent side, and buffer springs are installed on the outer sides of the plug-in column and the guide rod, and multiple groups of the buffer springs are respectively located inside the guide groove and the plug-in groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The stone processing grinding disc proposed by the utility model, after the stone and the grinding layer on the outer side of the grinding disc are sleeved together, the ratchet seat is rotated clockwise until the grinding layer is tightly abutted against the inner wall of the stone and then stops. During the rotation, the limit column will limit the rotation angle of the pawl to prevent the pawl from excessively rotating under the pushing action of the ratchet seat, and failing to have a reverse limiting effect on the ratchet seat. At this time, the power component installed with the connecting rod is started to drive the base, the grinding layer and the connecting rod to rotate in the reverse direction, so that the inside of the stone can be smoothly polished. The grinding range of the grinding disc can be adjusted according to the size of the stone, so that the inner wall of the stone can be polished to the same thickness.

[0023] Embodiment 1

[0024] See also Figures 1 to 3 The utility model provides a technical solution: a stone processing grinding disc, including a base 1, a grinding layer 2 and a connecting rod 3,

[0025] A polishing layer 2 is provided on the outside of the base 1, a connecting rod 3 is connected to the bottom of the base 1, guide grooves 101 are equidistantly provided inside the base 1, a guide rod 102 is inserted into the guide groove 101, one end of the guide rod 102 is connected to the polishing layer 2, a ratchet seat 4 and an adjusting arm 404 are provided on the upper side of the base 1, both ends of the adjusting arm 404 are hinged to the ratchet seat 4 and the inner wall of the polishing layer 2 through a mounting block and a pin shaft respectively, a pawl 401 is rotatably installed on the upper side of the base 1 through a rotating column, one end of the pawl 401 abuts against the ratchet seat 4, and the groove inside the base 1 is elastically connected to the limiting column 402 through a reset spring 403.

[0026] In specific implementation, according to Figures 1 to 3 , in order to make the grinding disc accurately grind according to the size of the stone, after the stone is sleeved with the grinding layer 2 on the outer side of the grinding disc, the ratchet seat 4 is rotated clockwise until the grinding layer 2 is tightly abutted against the inner wall of the stone and then stops. During the rotation, the limit column 402 will limit the rotation angle of the pawl 401 to prevent the pawl 401 from rotating excessively under the push of the ratchet seat 4, and the ratchet seat 4 cannot be reversely limited. At this time, the power component installed with the connecting rod 3 is started to drive the base 1, the grinding layer 2 and the connecting rod 3 to rotate in the opposite direction to smoothly grind the inside of the stone;

[0027] Among them, the limit column 402 is pressed downward, and the reset spring 403 is squeezed downward at this time. The ratchet seat 4 is rotated in the opposite direction to drive the grinding layer 2 to reset. After the grinding layer 2 is reset, the limit column 402 is released, and the limit column 402 is reset under the action of the reset spring 403, and the adjustment operation can be performed again. The stone processing grinding wheel can adjust the grinding range of the grinding wheel according to the size of the stone to prevent the inner wall from being polished with different thicknesses.

[0028] Embodiment 2

[0029] See also Figure 1 , Figure 4 and Figure 5 On the basis of the first embodiment, a connecting groove 501 is opened inside the base 1, and the base 1 is rotatably connected to the connecting layer 5 through the connecting groove 501. The top of the connecting layer 5 is connected to the ratchet seat 4. The top of the base 1 is connected to the extension layer 6, and the extension layer 6 has plug-in grooves 602 opened equidistantly inside. A plug-in column 601 is plugged into the plug-in groove 602, and one end of the plug-in column 601 is connected to the inner wall of the polishing layer 2 on the adjacent side. Buffer springs 603 are installed on the outside of the plug-in column 601 and the guide rod 102, and multiple groups of the buffer springs 603 are respectively located in the guide groove 101 and the plug-in groove 602.

[0030] In specific implementation, according to Figure 1 , Figure 4 and Figure 5 In order to improve the stability of the grinding layer 2 during use and extend the service life of the grinding layer 2, when the grinding layer 2 rotates and collides with the protrusion on the inner wall of the stone, the impact force will be transmitted to the buffer spring 603 through the connecting rod 3 and the plug-in column 601 on the inner side of the grinding layer 2 for buffering, thereby protecting the grinding layer 2 and preventing the grinding layer 2 from being directly damaged due to excessive hard impact. At the same time, the plug-in effect of the plug-in column 601 and the plug-in groove 602 in the extension layer 6 can assist the connecting rod 3 and the guide groove 101 to improve the guidance of the grinding layer 2 during adjustment. Among them, the bottom of the ratchet seat 4 is rotatably connected to the base 1 through the connecting layer 5 and the connecting groove 501, which can improve the stability of the grinding layer 2 during rotation. The stone processing grinding disc is provided with a plug-in groove 602 and a buffer spring 603 installed in the guide groove 101, which can buffer and divide the vibration generated by the grinding layer 2, effectively reduce the wear of the grinding layer 2, and increase the service life of the grinding layer 2.
