[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 4 As shown, a stainless steel pipe grinding device provided by an embodiment of the utility model includes a mounting frame 1, a grinding wheel 2 and a straight plate 3. The straight plate 3 is installed in the middle of the side wall of the mounting frame 1, and a through groove 4 is opened in the middle of the straight plate 3. A transmission shaft 5 is movably installed in the through groove 4, and a grinding wheel 2 is installed at the end of the transmission shaft 5. By adjusting the position change of the transmission shaft 5 in the through groove 4, the grinding operation of the grinding wheel 2 on the steel belt 6 is realized.

[0026] Specifically, the mounting frame 1 is a frame for conveying and installing the steel belt 6. The mounting frame 1 is provided with guide wheels. The number of the mounting frame 1 and the guide wheels is determined by the number of processing steps of the steel belt 6. The more processing steps the steel belt 6 has on the mounting frame 1, the more guide wheels there are on the mounting frame 1. When the steel belt 6 undergoes various processing steps, the guide wheels are required to convey the steel belt 6. The guide wheels convey the steel belt 6 to various processing step positions. The grinding wheel 2 is the most important type of abrasive tool in the grinding process. The grinding wheel 2 is a circular structure used for grinding the outer wall of the steel belt 6. The middle part of the through groove 4 is wider than the two ends thereof, so that the transmission shaft 5 can be movably installed in the through groove 4, and the transmission shaft 5 will not slip out of the through groove 4. When the steel belt 6 passes through the grinding wheel 2 under the conveying action of the guide wheel, the steel belt 6 is ground by the grinding wheel 2. However, when the friction time between the steel belt 6 and the grinding wheel 2 is long, the grinding wheel 2 is greatly worn, which affects the grinding effect of the grinding wheel 2 on the steel belt 6. After the grinding wheel 2 has been grinding the steel belt 6 for a long time, the transmission shaft 5 is adjusted to move the grinding wheel 2 in the groove 4, so that the position where the grinding wheel 2 does not rub against the steel belt 6 contacts the steel belt 6, so that the grinding wheel 2 can fully rub and grind with the steel belt 6, which will not affect the grinding quality of the grinding wheel 2 on the steel belt 6; in the prior art, the common steel belt 6 grinding structure is generally provided with a friction wheel on the frame, and the steel belt 6 is rubbed by the friction wheel. When the grinding wheel 2 passes through the same position of the friction wheel, the grinding part of the steel belt 6 is greatly worn, thereby affecting the grinding effect of the grinding wheel on the steel belt 6; in the present embodiment, when the grinding wheel 2 is greatly worn when grinding the steel belt 6, the position of the transmission shaft 5 in the through groove 4 is adjusted, and the transmission shaft 5 drives the grinding wheel 2 to move, and the friction position of the grinding wheel 2 and the steel belt 6 is adjusted, so that the grinding wheel 2 can fully rub and grind with the steel belt 6, and will not affect the grinding quality of the grinding wheel 2 on the steel belt 6.

[0027] Furthermore, a transmission wheel 7 is installed at the top of the transmission shaft 5, and a transmission groove 8 is opened at the top of the transmission wheel 7. A hollow sleeve shaft 9 is slidably installed in the transmission groove 8, and the hollow sleeve shaft 9 and the inner wall of the transmission groove 8 are connected by an elastic member 10; a square plate 11 is provided on the top of the side wall of the mounting frame 1, and a through groove 12 is opened in the middle of the square plate 11. A sliding plate 13 is slidably installed in the through groove 12, and a driving member 14 is installed at the bottom end of the sliding plate 13, and the output shaft of the driving member 14 and the hollow sleeve shaft 9 are slidably sleeved with each other.

[0028] Specifically, when it is necessary to drive the grinding wheel 2 to rotate, the position of the sliding plate 13 in the mounting frame 1 is adjusted so that the sliding plate 13 drives the driving member 14 (the driving member 14 is a device whose driving end can be reversed, preferably a motor) to move to a position where its output end and the hollow sleeve shaft 9 are slidably sleeved with each other, so that the output end of the driving member 14 is inserted into the hollow sleeve shaft 9, and the driving member 14 is started to drive the hollow sleeve shaft 9 to rotate, and the hollow sleeve shaft 9 drives the transmission wheel 7 to rotate, and the transmission wheel 7 drives the grinding wheel 2 to rotate, so that the grinding wheel 2 grinds the surface of the steel belt 6, and due to When the grinding wheel 2 rotates, the same position of the grinding wheel 2 will not rub against the steel belt 6 for too long, so that the grinding wheel 2 can fully grind the steel belt 6. When the driving member 14 vibrates axially, since the hollow sleeve shaft 9 is slidably installed in the transmission shaft 5, and an elastic member 10 is provided between the hollow sleeve shaft 9 and the inner wall of the transmission groove 8 (the elastic member 10 is a component that can be telescopically reset, preferably a spring) for shock absorption, the axial vibration of the driving member 14 will not affect the rotation of the grinding wheel 2, and further will not affect the grinding operation of the grinding wheel 2 on the steel belt 6.

[0029] Preferably, the square plate 11 is installed on the mounting frame 1 by means of a threaded connection, which facilitates the disassembly of the square plate 11. Specifically, the square plate 11 is installed by means of a threaded connection, and when the square plate 11 needs to be installed and disassembled, the staff can quickly install and disassemble it, thereby improving the efficiency of the installation of the square plate 11.

[0030] Furthermore, a screw 15 is rotatably provided between the inner walls in the middle of the through groove 12, and the screw 15 passes through the sliding plate 13 and is threadedly connected thereto; one end of the screw 15 passes through the square plate 11 and is connected to a rocker 16. Specifically, when it is necessary to adjust the position of the sliding plate 13 in the through groove 12, the staff rotates the rocker 16, and the rocker 16 drives the screw 15 to rotate. The screw 15 drives the sliding plate 13 to slide in the through groove 12 through threaded cooperation, so that the sliding plate 13 drives the output end of the driving member 14 to align with the hollow sleeve shaft 9, so that the output end of the driving member 14 can be plugged and connected with the hollow sleeve shaft 9.

[0031] Preferably, the straight plate 3 is slidably mounted on the mounting frame 1 to facilitate adjustment of the gap between the grinding wheel 2 and the steel belt 6. Specifically, when the gap between the grinding wheel 2 and the steel belt 6 needs to be adjusted, the gap between the grinding wheel 2 and the steel belt 6 can be adjusted by adjusting the position of the straight plate 3 on the mounting frame 1.

[0032] In another embodiment provided by the utility model, two symmetrical threaded rods 17 are arranged in the through groove 4, and a nut 18 is arranged on each end of the two threaded rods 17. The bottom end of the frame is located on the other side of the steel belt 6 and is symmetrically provided with the same straight plate 3, through groove 4, transmission shaft 5 and grinding wheel 2. The diameter of the transmission wheel 7 is the same as the diameter of the grinding wheel 2. The nuts 18 at both ends of the two threaded rods 17 are both tightly pressed against the outer wall of the transmission wheel 7. Specifically, before the grinding wheel 2 grinds the steel belt 6, the position of the transmission shaft 5 in the through groove 4 is adjusted so that the transmission shaft 5 drives the grinding wheel 2 to move to a suitable grinding position, and then the position of the threaded rod 17 in the through groove 4 is adjusted so that the nuts 18 at both ends of the threaded rod 17 are respectively tightly pressed against the corresponding transmission wheel 7 (such as Figure 4 As shown), the threaded rod 17 and the nut 18 perform positioning operation on the transmission wheel 7, so that when the steel belt 6 passes through the grinding wheel 2, the grinding wheel 2 can stably grind the steel belt 6. When the same position of the grinding wheel 2 rubs against the steel belt 6 for a long time, the position of the transmission wheel 7 and the transmission shaft 5 in the groove 4 is adjusted by adjusting the position of the threaded rod 17 in the groove 4, so that the position where the grinding wheel 2 does not rub against the steel belt 6 contacts the steel belt 6, so that the friction position between the grinding wheel 2 and the steel belt 6 can be adjusted, thereby improving the grinding effect of the grinding wheel 2 on the steel belt 6.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
