Description

Technical Field

[0001] The invention relates to the technical field of stone grinding, and in particular to a stone grinding device. Background Art

[0002] The stone grinding device is a device specially used for grinding and trimming stone. Stone is a common building material, widely used in construction, decoration, carving and other fields. Due to the high hardness of stone, conventional processing methods often cannot meet the needs of fine processing of stone, so a grinding device is needed to grind and trim stone.

[0003] The stone grinding device in the related technology, especially when processing columnar and tubular stones, requires higher processing accuracy when grinding their outer surfaces. However, the stone grinding device often vibrates slightly due to the existence of the power system. For stones with very high processing accuracy requirements, slight vibrations may also cause them to deviate from the expected size during processing, thereby affecting the overall quality and appearance. Summary of the invention

[0004] The purpose of the present invention is to provide a stone grinding device, which can improve the technical problem in the related art that vibration during grinding affects the quality of the stone.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A stone grinding device, comprising:

[0007] Base;

[0008] A grinding mechanism is located above the base and is rotatably connected to the base; the grinding mechanism includes a grinding correction mechanism for the stone tube to pass through, the grinding correction mechanism is used to grind the outer surface of the stone tube and correct the relative position between the stone tube and the grinding correction mechanism during the grinding process;

[0009] A first driving mechanism is fixedly connected to the base, a first power output end of the first driving mechanism is used to fix one end of the stone tube, a second power output end of the first driving mechanism is connected to the grinding mechanism, and the first driving mechanism is used to drive the grinding mechanism and the stone tube to rotate;

[0010] The second driving mechanism is fixedly connected to the base and is located at a side of the base away from the first driving mechanism, and is used for fixing the other end of the stone pipe away from the first driving mechanism.

Therefore, through the action of the first driving mechanism and the second driving mechanism, while fixing the stone tube and driving the stone tube to rotate, the grinding mechanism and its grinding correction mechanism can be driven to rotate, so that the grinding correction mechanism grinds the outer surface of the stone tube.

[0063] The stone grinding device is a device specially used for grinding and trimming stone. Stone is a common building material, widely used in construction, decoration, carving and other fields. Due to the high hardness of stone, conventional processing methods often cannot meet the needs of fine processing of stone, so a grinding device is needed to grind and trim stone.

[0064] The stone grinding device in the related technology, especially when processing columnar and tubular stones, requires higher processing accuracy when grinding their outer surfaces. However, the stone grinding device often vibrates slightly due to the existence of the power system. For stones with very high processing accuracy requirements, slight vibrations may also cause them to deviate from the expected size during processing, thereby affecting the overall quality and appearance.

[0065] Based on this, in order to improve the problem in the related art that the vibration during grinding affects the quality of the stone, the embodiment of the present invention provides the following solution.

[0066] See also Figure 1 and Figure 3 Now, the stone grinding device 100 provided by the embodiment of the present invention is described. The stone grinding device 100 includes a base 10, a grinding mechanism 20, a first driving mechanism 30 and a second driving mechanism 40, wherein:

[0067] The grinding mechanism 20 is located above the base 10 and is rotatably connected to the base 10; the grinding mechanism 20 includes a grinding correction mechanism 21 for the stone pipe to pass through, and the grinding correction mechanism 21 is used to grind the outer surface of the stone pipe and correct the relative position between the stone pipe and the grinding correction mechanism 21 during the grinding process.

[0068] The first driving mechanism 30 is fixedly connected to the base 10, and the first power output end of the first driving mechanism 30 is used to fix one end of the stone pipe. The second power output end of the first driving mechanism 30 is connected to the grinding mechanism 20, and the first driving mechanism 30 is used to drive the grinding mechanism 20 and the stone pipe to rotate.

[0069] The second driving mechanism 40 is fixedly connected to the base 10 and is located at a side of the base 10 away from the first driving mechanism 30 , and is used for fixing the other end of the stone pipe away from the first driving mechanism 30 .

[0070] It can be understood that the grinding and correcting mechanism 21 is a mechanism that can grind the stone tube and adjust the relative position between the grinding and correcting mechanism 21 and the stone tube. For example, the elastic adjustment member can be used to realize the elastic adjustment of the relative position between the stone tube and the grinding and correcting mechanism 21. Since the grinding and correcting mechanism 21 can allow the stone tube to pass through and grind its outer surface, it has a through hole structure for the stone tube to pass through and a grinding structure for grinding the stone tube.

[0071] As can be seen from the above, the stone grinding device 100 provided in the embodiment of the present invention is different from the prior art in that the grinding mechanism 20 is located above the base 10 and is rotatably connected to the base 10; and the first driving mechanism 30 is fixedly connected to the base 10, and the first power output end of the first driving mechanism 30 drives the stone tube to rotate, and the second power output end drives the grinding mechanism 20 to rotate; the second driving mechanism 40 is connected to the base 10 and is located on the side of the base 10 away from the first driving mechanism 30, and can fix one end of the stone tube away from the first driving mechanism 30. Therefore, through the action of the first driving mechanism 30 and the second driving mechanism 40, while fixing the stone tube and driving the stone tube to rotate, the grinding mechanism 20 and its grinding correction mechanism 21 can be driven to rotate, so that the grinding correction mechanism 21 grinds the outer surface of the stone tube. The design of the first driving mechanism 30 and the second driving mechanism 40 enables the stone tube to be stably fixed on the device, thereby ensuring the stability and accuracy of the grinding process. By means of this device, the stone pipe can be ground efficiently to make its surface flat, smooth and bright.

[0072] At the same time, during the process of grinding the outer surface of the stone tube by the grinding correction mechanism 21, the relative position between the stone tube and the grinding correction mechanism 21 can be corrected, which can reduce the influence of the vibration generated during the operation of the stone grinding device 100 on the grinding of the stone tube and reduce the possibility of the stone tube deviating from the expected size. In other words, the grinding correction mechanism 21 can reduce the relative vibration amplitude between the stone tube and the grinding correction mechanism 21 during the grinding process, thereby stabilizing the relative position between the stone tube and the grinding correction mechanism 21 to improve the grinding quality of the stone tube.

[0073] In some embodiments, see Figure 1 and Figure 5 The grinding mechanism 20 further includes a support frame 22, which is located above the base 10 and rotatably connected to the base 10. The grinding correction mechanism 21 is linearly movable on the support frame 22. The second power output end of the first driving mechanism 30 is connected to the grinding correction mechanism 21, and is used to drive the grinding correction mechanism 21 to rotate and linearly move.

[0074] It can be understood that the linear movement of the grinding and correcting mechanism 21 means that the grinding and correcting mechanism 21 moves along the axial direction of the stone tube, thereby grinding the outer surface of the stone tube.

[0075] In this configuration, the grinding correction mechanism 21 is driven to rotate by the second power output end of the first driving mechanism 30, so that the grinding correction mechanism 21 grinds the stone pipe. At the same time, the second power output end also drives the grinding correction mechanism 21 to move linearly on the support frame 22, so that the grinding correction mechanism 21 can move linearly along the axial direction of the stone pipe, so that the grinding correction mechanism 21 grinds the outer surface of the stone pipe. The grinding correction mechanism 21 can be rotated and linearly moved by the first driving mechanism 30, so that the circumferential outer surface of the stone pipe can be fully ground. The combination of rotation and linear movement can ensure the uniformity and consistency of the grinding process. The linear movement of the grinding correction mechanism 21 can make the grinding process more precise and stable, so as to achieve a better grinding effect and improve the grinding quality of the stone pipe.

[0076] Optionally, in some embodiments, see Figure 1 , Figure 3 and Figure 5 The support frame 22 includes a first support plate 221, a second support plate 222 and a plurality of guide rods 223, wherein:

[0077] The first support plate 221 is located above the base 10 and is rotatably connected to a side of the base 10 close to the first driving mechanism 30. A first through hole 22101 is provided at the center of the first support plate 221. The first driving mechanism 30 passes through the first through hole 22101 and is connected to one end of the stone tube.

[0078] The second support plate 222 is located above the base 10 and is rotatably connected to a side of the base 10 close to the second driving mechanism 40. A second through hole 22201 is provided at the center of the second support plate 222. The diameter of the second through hole 22201 is larger than the outer diameter of the stone tube. The second driving mechanism 40 is passed through the second through hole 22201 and connected to the other end of the stone tube.

[0079] One end of the guide rod 223 is fixedly connected to the first support plate 221 , and the other end of the guide rod 223 is fixedly connected to the second support plate 222 ; the grinding deviation correction mechanism 21 is linearly movably disposed on the guide rod 223 .

[0080] It is understood that the connection between the first support plate 221 and the second support plate 222 and the base 10 can be through a bearing connection, or can be through a gear matching connection to achieve the mutual rotation between the first support plate 221 and the base 10 and between the second support plate 222 and the base 10, but it is not limited thereto. The driving force when the first driving mechanism 30 drives the grinding correction mechanism 21 to move linearly is greater than the sum of the friction between the guide rod 223 and the grinding correction mechanism 21 and the friction between the grinding correction mechanism 21 and the stone pipe.

[0081] With such arrangement, when loading, the stone tube passes through the second through hole 22201, passes through the second support plate 222, and then passes through the grinding correction mechanism 21, and then abuts against the first support plate 221. The first drive mechanism 30 and the second drive mechanism 40 clamp the two ends of the stone tube through the first through hole 22101 and the second through hole 22201, respectively, to stabilize the stone tube. When grinding, the first drive mechanism 30 drives the grinding correction mechanism 21 and the stone tube to rotate relative to each other, and the grinding correction mechanism 21 drives the guide rod 223 to rotate circumferentially around the axis of the grinding correction mechanism 21, and the guide rod 223 then drives the first support plate 221 and the second support plate 222 to rotate. At the same time, the first driving mechanism 30 drives the grinding and correcting mechanism 21 to move linearly, so that the grinding and correcting mechanism 21 moves along the axial direction of the guide rod 223 while rotating, thereby realizing the grinding of the outer surface of the stone tube. The guide rod 223, the first support plate 221 and the second support plate 222 guide and support the grinding and correcting mechanism 21, ensuring the stability and accuracy of the grinding and correcting mechanism 21 during the grinding process, thereby achieving a better grinding effect.

[0082] Optionally, see Figure 5 and Figure 6 The grinding and correcting mechanism 21 includes a support ring 211, a grinding head 212 and a plurality of elastic members 213, wherein:

[0083] The support ring 211 can be linearly movably arranged on the guide rod 223 and is arranged perpendicular to the guide rod 223 (the axis of the support ring 211 is roughly parallel to the axis of the guide rod 223); the support ring 211 has a support through hole 21101.

[0084] The grinding head 212 is located in the supporting through hole 21101; the grinding head 212 has a grinding through hole 21201 for the stone pipe to pass through, and the grinding head 212 is used to grind the circumferential outer surface of the stone pipe.

[0085] Each elastic member 213 is circumferentially arranged in the support through hole 21101 around the grinding head 212, one end of the elastic member 213 is connected to the inner wall of the support through hole 21101, and the other ends of the elastic members 213 are connected to the outer wall of the grinding head 212;

[0086] The second power output end of the first driving mechanism 30 is connected to the support ring 211 to drive the support ring 211 to rotate and move linearly.

[0087] It can be understood that the grinding through hole 21201 of the grinding head 212 is a circular through hole, and the inner diameter of the grinding through hole 21201 is slightly larger than the outer diameter of the stone tube. A grinding material layer (such as diamond, silicon carbide, etc.) that can grind the stone tube can be provided on the inner wall of the grinding through hole 21201. Optionally, the axis of the grinding through hole 21201 can slightly deviate from the axis of the stone tube (the degree of deviation can be set according to actual needs, for example, the axis of the grinding through hole 21201 of the grinding head 212 can be deviated from the axis of the stone tube by changing the length or material of part of the elastic member 213, and the elastic member 213 can be detachably connected with the inner wall of the supporting through hole 21101 and the outer wall of the grinding head 212, such as threaded connection or snap connection), that is, the two are not completely coaxially arranged, which is conducive to the inner wall of the grinding through hole 21201 to abut against the outer wall of the stone tube, thereby improving the grinding effect of the grinding head 212 on the stone tube. The elastic member 213 may be a spring, a reed, etc., but is not limited thereto.

[0088] With such arrangement, when loading, the stone tube passes through the second through hole 22201, passes through the second support plate 222, and then passes through the grinding through hole 21201, and then abuts against the first support plate 221, and then the inner walls of both ends of the stone tube are abutted and clamped by the first driving mechanism 30 and the second driving mechanism 40. When grinding, the first driving mechanism 30 drives the support ring 211 to rotate, and the support ring 211 drives the guide rod 223 to rotate. When the support ring 211 rotates, it drives the elastic member 213 and the grinding head 212 in the support through hole 21101 to rotate circumferentially around the stone tube, so that the grinding head 212 starts to grind the outer surface of the stone tube. At the same time, the first driving mechanism 30 drives the support ring 211 to move linearly, so that the support ring 211 moves along the axial direction of the guide rod 223 while rotating, and the support ring 211 drives the grinding head 212 to move in the axial direction of the stone tube, thereby realizing the grinding of the outer surface of the stone tube. The grinding head 212 can achieve precise grinding of the outer surface of the stone tube through the rotation and linear movement of the support ring 211. The rotation of the support ring 211 enables the grinding head 212 to rotate circumferentially around the stone tube, while the linear movement of the support ring 211 enables the grinding head 212 to move along the axial direction of the stone tube, thereby achieving comprehensive grinding of the circumferential outer surface of the stone tube.

[0089] Since multiple elastic members 213 are connected to the outer wall of the grinding head 212 and the inner wall of the supporting through hole 21101, elastic support is provided, and the grinding head 212 is kept in good contact with the surface of the stone tube. At the same time, the elastic members 213 can reduce the vibration and vibration during the grinding process, and further improve the stability and consistency of the grinding. Even if the stone tube vibrates slightly during grinding due to external factors or the stone grinding device 100 itself, the adaptability of the elastic members 213 can keep the grinding head 212 in good contact with the surface of the stone tube, thereby achieving accurate grinding of the outer surface of the stone tube.

[0090] Optionally, the grinding head 212 includes a plurality of grinding parts, each of which is an arc-shaped structure, each of which is arranged to form a ring-shaped grinding head 212, and each of which is surrounded by a grinding through hole 21201, and a gap is provided between two adjacent grinding parts. Each grinding part is connected to the inner wall of the supporting through hole 21101 through each elastic member 213. With such a configuration, each grinding part of the grinding head 212 is a relatively discrete and independent grinding part, and under the action of the elastic member 213, each grinding part can be respectively abutted against different parts of the circumferential outer surface of the stone tube, which can effectively increase the contact area between the grinding head 212 and the stone tube, and can adapt to the local irregular parts of the stone tube, thereby improving the grinding effect.

[0091] Optionally, see Figure 6 and Figure 7A first threaded hole 21102 is formed on the support ring 211 ; a second threaded hole 21203 is formed on the outer wall of the grinding head 212 ; the stone grinding device 100 further includes a locking rod 214 , which is threadedly connected to the first threaded hole 21102 and the second threaded hole 21203 .

[0092] It can be understood that the two ends of the locking rod 214 connected to the support ring 211 and the grinding head 212 are respectively provided with a first external thread and a second external thread that match the first threaded hole 21102 and the second threaded hole 21203, and the thread directions are consistent. The aperture of the first threaded hole 21102 is greater than or equal to the aperture of the second threaded hole 21203. When the aperture of the first threaded hole 21102 is greater than the aperture of the second threaded hole 21203, the end of the locking rod 214 with the second external thread is directly passed through the first threaded hole 21102, and then the locking rod 214 is rotated so that the locking rod 214 is threadedly connected with the first threaded hole 21102 and the second threaded hole 21203. When the aperture of the first threaded hole 21102 is equal to the aperture of the second threaded hole 21203, the diameters of the first external thread and the second external thread are the same, then one end of the locking rod 214 is selected, and the locking rod 214 is rotated to first pass one end of the locking rod 214 through the first threaded hole 21102, and then the locking rod 214 is rotated again, so that the locking rod 214 is threadedly connected with the first threaded hole 21102 and the second threaded hole 21203. In the former case, when one end of the locking rod 214 is penetrated with the first threaded hole 21102, it is faster and more convenient, and the time of connection can be saved. In the latter case, when connecting, there is no need to distinguish the two ends of the locking rod 214. After one end is selected to pass through the first threaded hole 21102, the locking rod 214 is threadedly connected with the first threaded hole 21102 and the second threaded hole 21203, which can reduce the complexity of the operation and the possibility of error, and maintain the consistency of the workpiece. These two cases have their own advantages. In specific applications, a suitable connection method can be selected according to the actual situation and operation requirements to achieve better results.

[0093] With such arrangement, before loading, the locking rod 214 is first connected to the support ring 211 and the grinding head 212, so that the grinding head 212 is in a suitable position in the support through hole 21101, and the relative position of the grinding head 212 and the support ring 211 is kept stable, and then the stone tube passes through the second through hole 22201, and then passes through the grinding through hole 21201, and finally abuts the first support plate 221. Since the support ring 211 and the grinding head 212 are connected by a plurality of elastic members 213, and the grinding through hole 21201 of the grinding head 212 is close to the outer diameter of the stone tube, the relative position of the support ring 211 and the grinding head 212 can be fixed by the locking rod 214, so as to prevent the grinding head 212 from moving when the stone tube passes through the grinding through hole 21201, thereby increasing the difficulty of loading. At the same time, by fixing the position of the grinding head 212 through the locking rod 214, the grinding head 212 can have a certain guiding effect, so that the stone pipe can be in a suitable horizontal position after passing through the grinding head 212 and abutting against the first support plate 221, so that the first driving mechanism 30 can clamp and fix one end of the stone pipe through the first through hole 22101. After fixing, the second driving mechanism 40 clamps and fixes the other end of the stone pipe, so that the stone pipe is firmly fixed on the stone grinding device 100. Finally, the locking rod 214 is removed from the support ring 211, and then the stone pipe is ground. In short, through the fixing effect of the locking rod 214, the relative position of the grinding head 212 and the support ring 211 can be guaranteed to remain stable during the feeding process, preventing the grinding head 212 from moving and increasing the difficulty of feeding. At the same time, the locking rod 214 can also play a guiding role, so that the stone pipe is in a suitable horizontal position when passing through the grinding head 212, which is convenient for the first driving mechanism 30 to clamp and fix it. After the stone tube is fixed, the locking rod 214 is removed and the grinding operation is performed to finally realize the grinding of the stone. When the grinding is completed, the first driver 32 controls the support ring 211 to move to fit with the second support plate 222. In this way, when taking out the stone tube, there is no need to fix the grinding head 212 with the locking rod 214. The stone tube only needs to be taken out from the second through hole 22201. When taking it out, the grinding head 212 will abut against the second support plate 222 to achieve the effect of stabilizing the position of the grinding head 212, thereby facilitating the unloading of the stone tube.

[0094] In some embodiments, see Figure 1 and Figure 3 The first driving mechanism 30 includes a first clamping member 31, a first driver 32, a first gear 33, a second gear 34, a third gear 35 and a driving rod 36, wherein:

[0095] One end of the first clamping member 31 passes through the first through hole 22101 and is clamped on the stone pipe.

[0096] The first driver 32 is fixedly connected to the base 10 , and an output end of the first driver 32 is connected to the other end of the first clamping member 31 for driving the first clamping member 31 to rotate.

[0097] The first gear 33 is fixed on the first clamping member 31 .

[0098] The second gear 34 is connected to the base 10 and meshes with the first gear 33 .

[0099] The third gear 35 meshes with the second gear 34 .

[0100] One end of the driving rod 36 is fixed to the third gear 35 and is rotatably connected to the base 10 , and the other end of the driving rod 36 is rotatably connected to the base 10 ; the driving rod 36 is connected to the support ring 211 for driving the support ring 211 to rotate and move linearly.

[0101] It can be understood that the axial position of the first clamping member 31 remains unchanged, and is located on the side of the first support plate 221 close to the second support plate 222. The first clamping member 31 can be a clamping member capable of clamping a tubular body, such as a mechanical clamping member, an electronic clamping member, a pneumatic clamping member, or a hydraulic clamping member, but is not limited thereto. The first driver 32 can be a motor, etc., but is not limited thereto.

[0102] With such arrangement, when loading, after the stone tube is placed in the grinding and correcting mechanism 21, one end of the stone tube has abutted against the first support plate 221, and the first clamping member 31 is located in the internal space of the stone tube, and then the first clamping member 31 clamps the stone tube by abutting against the inner wall of the stone tube. It should be noted here that the clamping of the first clamping member 31 can be driven manually or by other driving devices. After the first clamping member 31 and the second driving mechanism 40 clamp the stone tube, the first driver 32 drives the first clamping member 31 to rotate. At this time, the first clamping member 31 drives the stone tube and the first gear 33 to rotate in the same direction. At the same time, through the meshing connection of the first gear 33, the second gear 34 and the third gear 35, the third gear 35 and the first clamping member 31 rotate in the same direction, that is, the rotation direction of the driving rod 36 is the same as the rotation direction of the first clamping member 31. The driving rod 36 then drives the support ring 211 to rotate, so that the support ring 211 rotates in the opposite direction to the first clamping member 31, that is, the grinding head 212 rotates in the opposite direction to the stone tube. Thereby increasing the magnitude of the grinding force, the relative rotation increases the friction between the grinding head 212 and the stone tube, so that the grinding head 212 fits the surface of the stone tube more closely, thereby grinding the surface of the stone tube more effectively, improving the quality and efficiency of grinding, and ensuring the surface smoothness and precision of the stone tube.

[0103] Optionally, in some embodiments, see Figure 3 and Figure 4 , the driving rod 36 includes a rod body 361 and a spiral portion 362, wherein:

[0104] One end of the rod body 361 is fixed to the third gear 35 and is rotatably connected to the base 10 , and the other end of the rod body 361 is rotatably connected to the base 10 .

[0105] The spiral portion 362 is connected to the rod body 361 , and the outer edge of the support ring 211 is located in the spiral gap of the spiral portion 362 and abuts against the spiral portion 362 .

[0106] The grinding correction mechanism 21 also includes a plurality of baffles 215, which are circumferentially arranged on the outer wall of the support ring 211; a plurality of paddles 363 are sequentially arranged on the outer wall of the driving rod 36 in the spiral gap along the spiral direction of the spiral portion 362, and the side walls of the baffles 215 are abutted against the side walls of the paddles 363.

[0107] It can be understood that the width of the baffle 215 is similar to that of the paddle 363, that is, both are smaller than the wall width between the two side walls of the spiral gap. The spiral portion 362 is a spiral structure, and is spirally arranged on the outer side wall of the rod body 361 along the axial direction of the rod body 361. The spiral portion 362 and the rod body 361 can be an integrally formed one-piece structure, or they can be separately formed and assembled. The spiral gap is the gap formed between two adjacent spiral ring structures of the spiral portion 362.

[0108] With such arrangement, when the first driver 32 drives the rod 36 to rotate through the third gear 35, the spiral portion 362 and the rod body 361 rotate around the axis of the rod body 361, and the support ring 211 located in the spiral gap is driven by the rotation of the spiral portion 362, so that the support ring 211 moves linearly along the axis of the rod body 361. At the same time, when the rod body 361 rotates, the paddles 363 also rotate around the rod body 361, and during the rotation of the paddles 363, one of the paddles 363 will rotate to abut against one of the baffles 215, and the paddle 363 will continue to rotate, so the paddle 363 will push the baffle 215, so that the baffle 215 drives the support ring 211 to rotate until the paddle 363 is separated from the baffle 215, and after the baffle 215 is separated from the paddle 363, the next paddle 363 will push the next baffle 215, so that the support ring 211 continues to rotate, and the multiple baffles 215 are pushed in turn by multiple paddles 363, so that the support ring 211 can rotate continuously and stably. In this way, the drive rod 36 and the grinding correction mechanism 21 of this structure are set, so that the grinding correction mechanism 21 can realize rotation and linear movement through the drive rod 36. At the same time, the coordination and driving of the mechanical structure improves the stability of the grinding process and the grinding effect of the stone grinding device 100.

[0109] Optionally, a ring groove is formed on the circumferential outer wall of the support ring 211, and the baffle 215 is disposed on the inner bottom wall of the ring groove. This arrangement saves the space of the support ring 211 as a whole, makes the connection between the support ring 211 and the driving rod 36 more compact, and further improves the stability of the device, thereby improving the grinding quality of the stone pipe.

[0110] Optionally, see Figures 1 to 3 , the second driving mechanism 40 comprises a second clamping member 41 and a second driver 42, wherein:

[0111] One end of the second clamping member 41 passes through the second through hole 22201 and is clamped on the stone pipe.

[0112] The second driver 42 is disposed on the base 10 , and an output end of the second driver 42 is connected to the other end of the second clamping member 41 , so as to drive the second clamping member 41 to clamp or release the stone pipe.

[0113] It can be understood that the second driver 42 can be a motor, a screw transmission device, etc., but is not limited thereto.

[0114] With such arrangement, during feeding, when the stone tube is fed into the grinding and correcting mechanism 21 and abuts against the first support plate 221, the second driver 42 drives the second clamping member 41 to clamp the stone tube, so as to stabilize the stone tube.

[0115] Optionally, see Figure 1 and Figure 2 The base 10 includes a curved guide rail 11, and the second driving mechanism 40 is movably connected to the curved guide rail 11; the curved guide rail 11 includes a first guide rail 111 and a second guide rail 112, wherein:

[0116] The first guide rail 111 is located at one end close to the second support plate 222 and is arranged along the axial direction of the stone pipe.

[0117] The second guide rail 112 is connected to the first guide rail 111 and forms an angle with the first guide rail 111 .

[0118] With such arrangement, before loading, the second driving mechanism 40 is first moved from the first guide rail 111 to the second guide rail 112. At this time, the second clamping member 41 deviates from the second through hole 22201 to facilitate the placement of the stone tube from the second through hole 22201 into the grinding and correcting mechanism 21; after the stone tube is placed, the second driving mechanism 40 is moved from the second guide rail 112 to the first guide rail 111, and continues to move closer to the second support plate 222, so that the second clamping member 41 moves closer to the stone tube until it moves to the internal space of the stone tube, and the second driver 42 controls the second clamping member 41 to act on the inner wall of the stone tube to clamp the stone tube. When unloading, first move the second drive mechanism 40 from the first guide rail 111 to the second guide rail 112. During this process, the second clamping member 41 clamps the stone tube and moves from the grinding and correcting mechanism 21 to the second support plate 222. When the second clamping member 41 moves from the second support plate 222 to the other side close to the first support plate 221, that is, when the second clamping member 41 has been separated from the second support plate 222, and the second drive mechanism 40 is close to the second guide rail 112, the second driver 42 drives the second clamping member 41 to release the stone tube. At this time, the stone tube can be unloaded. In this way, by setting the first guide rail 111 and the second guide rail 112, space can be vacated during loading to make it more convenient to load the stone tube. When unloading, the second driving mechanism 40 moves on the first guide rail 111, so that the second clamping member 41 can clamp the stone tube and move away from the grinding correction mechanism 21, thereby helping unloading and facilitating loading and unloading.

[0119] In some embodiments, see Figures 1 to 3 and Figure 5 , the diameter of the first through hole 22101 is smaller than the outer diameter of the stone tube; the second clamping member 41 includes a clamping rod 411 and a clamping head 412, wherein:

[0120] The clamping rod 411 is arranged in the axial direction of the stone pipe; one end of the clamping rod 411 is connected to the power output end of the second driver 42 .

[0121] The clamping head 412 is rotatably connected to the other end of the clamping rod 411 .

[0122] The grinding mechanism 20 further includes a first grinding sheet 23 and a second grinding sheet 24. The first grinding sheet 23 is disposed on one side of the first support plate 221 close to the second driving mechanism 40, and is used to grind the end surface of one end of the stone tube. The second grinding sheet 24 is disposed on one end of the clamping rod 411 close to the clamping head 412, and is used to grind the end surface of the other end of the stone tube.

[0123] It can be understood that when the clamping head 412 clamps the stone tube, the first grinding sheet 23 fits with the end face of one end of the stone tube, and the second grinding sheet 24 fits with the end face of the other end of the stone tube. The second driver 42 controls the clamping head 412 to clamp or release the stone tube through the clamping rod 411, and the clamping rod 411 does not rotate. For example, the clamping head 412 can be a mechanical clamp, a pneumatic clamp, a hydraulic clamp, an electronic clamp, etc., and through a transmission device (such as a lever transmission mechanism, a pneumatic transmission mechanism, a hydraulic transmission mechanism, a circuit transmission device, etc.) arranged inside the clamping rod 411, its two ends are respectively connected to the output end of the second driver 42 and the input end of the clamping head 412, so as to achieve the purpose of the clamping rod 411 controlling the clamping head 412 to clamp or release the stone tube.

[0124] With such arrangement, when grinding the stone tube, the clamping head 412 abuts against the inner wall of the stone tube, so that the clamping head 412 rotates synchronously with the stone tube, the clamping rod 411 and the second grinding sheet 24 fixed on the clamping rod 411 do not rotate either, the grinding head 212 grinds the circumferential outer surface of the stone tube, the first grinding sheet 23 rotates relative to the stone tube, that is, the first grinding sheet 23 grinds one end of the stone tube; the second grinding sheet 24 rotates relative to the stone tube, that is, the second grinding sheet 24 grinds the other end of the stone tube, so as to achieve the purpose of comprehensive grinding of the stone tube.

[0125] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
