As described in the background art, during polishing, coarse abrasive paper is fixed on a polishing disk to remove an oxide layer on the surface of an object to be polished. Then, the coarse abrasive paper is removed, and the fine abrasive paper with more than 1000 meshes is fixed on the polishing disc so as to finish the surface of the object to be polished. Then, the fine grinding sand paper is removed, and the polishing cloth is fixed on the polishing disc so as to polish the surface of the object to be polished and remove scratches. The rough grinding process, the fine grinding process and the polishing process are completed in the same station, the processing waiting time is long, and the grinding and polishing efficiency is restricted.

In order to improve the above problems, referring to fig. 1, 2, 3, 4, 5, and 6, there is provided a grinding polisher including a coarse grinding unit 110, a fine grinding unit 120, and a polishing unit 130. Wherein the rough grinding unit 110 is used for rough grinding of the object to be polished. The fine grinding unit 120 is disposed at one side of the coarse grinding unit 110 for fine grinding the object to be polished. The polishing unit 130 is disposed at a side of the fine grinding unit 120 remote from the coarse grinding unit 110, and is used for fine grinding the object to be polished. The rough grinding unit 110, the fine grinding unit 120, and the polishing unit 130 are disposed in parallel with each other so that the rough grinding process, the fine grinding process, and the polishing process can be completed at three stations. In the same time period, three objects to be polished can be respectively subjected to rough grinding, fine grinding and polishing, so that the processing waiting time is shortened, and the grinding and polishing efficiency and the production beat are improved. It should be noted that, when the object to be polished is transferred between the three stations, it can be accomplished by manpower, mechanical clamping jaw or driving mechanism.

Specifically, in the illustrated example, the coarse grinding unit 110 includes a first transmission gear 111, coarse sandpaper 112, and a first tension adjuster 113. The first transmission gears 111 are two, and the end surfaces are parallel to each other. The coarse abrasive paper 112 is provided with two rows of first abdicating holes into which the gear teeth of the two first transmission gears 111 are respectively inserted. The gear teeth cooperate with the first relief holes to effectively prevent the coarse sandpaper 112 from deviating. It should be noted that coarse abrasive paper 112 is no more than 800 mesh paper. The coarse sand paper 112 is wound around the first transmission gear 111, and rotates with the rotation of the first transmission gear 111. When the object to be polished is coarsely ground, the object to be polished is placed under the first transmission gear 111. The coarse sand paper 112 rotating with the first transmission gear 111 can perform coarse grinding on the object to be polished, so as to achieve the purpose of removing the oxide layer on the surface of the object to be polished, and make the surface of the object to be polished flat. The first tension adjuster 113 is disposed on one side of and above the first transmission gear 111. The coarse abrasive paper 112 is wound around the first transmission gear 111 and the first tension adjuster 113, and the tension of the coarse abrasive paper 112 is adjusted by the first tension adjuster 113, so that the coarse abrasive effect is ensured.

Specifically, in the exemplary embodiment, fine grinding unit 120 includes a second drive gear 121, fine abrasive paper 122, and a second tensioning device 123. The end face of the second transmission gear 121 and the end face of the first transmission gear 111 are parallel to each other. The number of the second transmission gears 121 is two, and the end surfaces are parallel to each other. The fine abrasive paper 122 is provided with two rows of second abdicating holes for respectively inserting the gear teeth of the two second transmission gears 121. The gear teeth cooperate with the second relief holes to effectively prevent the fine sandpaper 122 from deviating. It should be noted that fine abrasive paper 122 is not less than 1200 mesh paper. The fine abrasive paper 122 is wound around the second transmission gear 121 and rotates with the rotation of the second transmission gear 121. When the object to be polished is finely ground, the object to be polished is placed under the second transmission gear 121. The fine abrasive paper 122 rotated with the second transmission gear 121 is capable of finely grinding an object to be polished to remove coarse scratches generated during the rough grinding process, so that the scratches reach the polishing grade of thickness. The second tension adjuster 123 is disposed on one side of and above the second transmission gear 121. The fine abrasive paper 122 is wound around the second transmission gear 121 and the second tension adjuster 123, and the tension of the fine abrasive paper 122 is adjusted by the second tension adjuster 123, so that the fine abrasive effect is ensured.

Specifically, in the exemplary embodiment, polishing unit 130 includes a third transmission gear 131, a polishing cloth 132, and a third tension adjuster 133. The end face of the third transmission gear 131 and the end face of the second transmission gear 121 are parallel to each other. The number of the third transmission gears 131 is two, and the end surfaces are parallel to each other. The polishing cloth 132 is provided with two rows of third abdicating holes for respectively inserting the gear teeth of the two second transmission gears 121. The gear teeth cooperate with the second relief holes to effectively prevent the polishing cloth 132 from deviating. It should be noted that the polishing cloth 132 is coated with a polishing liquid or a polishing paste. The polishing cloth 132 is wound around the third transmission gear 131 and rotates with the rotation of the third transmission gear 131. When polishing the object to be polished, the object to be polished is placed under the third transmission gear 131. The polishing cloth 132 rotated with the third transmission gear 131 can polish the object to be polished to remove fine scratches generated during the fine grinding process. The third tension adjuster 133 is disposed above and beside the third transmission gear 131. The polishing cloth 132 is wound on the third transmission gear 131 and the third tension adjuster 133, and the tension of the polishing cloth 132 is adjusted by the third tension adjuster 133, thereby guaranteeing the polishing effect.

Typically, the object to be polished is used as a raw material for corrosion metallographic phase. For some special materials such as spheroidal graphite cast iron, the spheroidal graphite cast iron is easy to be rapidly oxidized and corroded by water and air. Thus, it is necessary to control the duration of the rough grinding process, the finish grinding process, and the polishing process. Compared with the traditional grinding and polishing machine, the abrasive paper with different mesh numbers is not required to be replaced once before each procedure is carried out, the waiting time is shortened, reworking is not required, and metallographic analysis is facilitated.

Specifically, in the illustrated example, the grinder/polisher further includes a drive rod 140, a drive motor, and a bearing 180. One end of the transmission rod 140 is sleeved with a first transmission gear 111, the middle part is sleeved with a second transmission gear 121, and the other end is sleeved with a third transmission gear 131. The same transmission rod 140 is adopted to drive the first transmission gear 111, the second transmission gear 121 and the third transmission gear 131 to rotate, so that the rough grinding unit 110, the fine grinding unit 120 and the polishing unit 130 can work simultaneously. The casing of the driving motor is fixed on the casing 160, and the output end is fixedly connected with one end of the driving rod 140, so that the driving rod 140 can be driven to rotate, and further the first driving gear 111, the second driving gear 121 and the third driving gear 131 are driven to rotate. The same driving source is adopted, so that the cost is greatly reduced, and the energy utilization rate is improved. One end of the transmission rod 140, which is close to the motor, is rotatably connected with one end of the housing 160 through a bearing 180. As shown in fig. 6, a positioning and mounting groove 181 is provided in the middle of the bearing 180, and the positioning and mounting groove 181 is communicated with a mounting hole in the middle of the bearing 180. A positioning and mounting bar is provided on a sidewall of the driving lever 140 in an axial direction of the driving lever 140. The section of the positioning and mounting strip is matched with the positioning and mounting groove 181 so as to facilitate the positioning and dismounting of the transmission rod 140.

Specifically, in the illustrated example, the grinder/polisher further includes a base 150 and a housing 160. The base 150 is disposed under the rough grinding unit 110, the fine grinding unit 120, and the polishing unit 130. The inside of the housing 160 is installed with the rough grinding unit 110, the fine grinding unit 120, and the polishing unit 130, and is mounted on the base 150. It should be noted that, the inside of one end of the housing 160 is a driving motor accommodating cavity, the inside of the middle is a coarse grinding unit 110 accommodating cavity, a fine grinding unit 120 accommodating cavity, and the inside of the other end is a polishing unit 130 accommodating cavity.

One of the water inlet holes 161 is provided above the rough grinding unit 110, the other water inlet hole 161 is provided above the fine grinding unit 120, and the other water inlet hole 161 is provided above the polishing unit 130. Water is supplied through the three water inlet holes 161 to the coarse sandpaper 112 of the coarse grinding unit 110, the fine sandpaper 122 of the fine grinding unit 120, and the polishing cloth 132 of the polishing unit 130, respectively, to improve the coarse grinding effect, the fine grinding effect, and the polishing effect. And/or, a drain groove 151 is provided on the base 150, and the drain groove 151 is located at the middle of the top surface of the base 150, and is capable of receiving water and debris. A drain hole 162 communicating with the drain groove 151 is provided at the bottom of one end of the housing 160. The grinder/polisher further includes three water supply pipes 170. The three water supply pipes 170 are all installed on the housing 160, and the water outlets of the three water supply pipes face the water inlet holes 161 in a one-to-one correspondence manner.

The third guiding cylinder 1333 is disposed on one side of the first transmission gear 111, and has an axis perpendicular to the first transmission gear 111, and one end fixedly connected to an inner wall of the accommodating cavity of the rough grinding unit 110. Both ends of the support bar 1334 are connected to the first guide cylinder 1331 and the second guide cylinder 1332, respectively. The axis slope setting of tight spring 1335 in top is connected with the middle part of bracing piece 1334, and the bottom is fixed connection with the third guide cylinder. The coarse sandpaper 112 sequentially passes around the first transmission gear 111, the first guide cylinder 1331, the second guide cylinder 1332, and the third guide cylinder 1333. When the coarse sand paper 112 is used for a long time, the force of the restoring deformation of the tightening spring 1335 drives the supporting rod 1334 to move upwards, and then drives the first guide cylinder 1331 and the second guide cylinder 1332 to move upwards, so that the coarse sand paper 112 is tightly attached to each component. Through holes are respectively formed at two opposite ends of the first guide cylinder 1331, and a limiting hole is formed at one side of the first guide cylinder. Through holes are respectively formed at two opposite ends of the second guide cylinder 1332, and a limiting hole is formed at one side of the second guide cylinder. The first spacers 13361 are provided at both ends of the first guide cylinder 1331. The first spring 13371 is inserted into the first guiding cylinder 1331, and two ends of the first spring are fixedly connected with the two first gaskets 13361 respectively. The first mounting bars 13381 are two, one ends of the first mounting bars are fixedly connected with the two first gaskets 13361 respectively, and the other ends of the first mounting bars extend out of the first guide cylinder 1331 through the through holes respectively. Two second gaskets 13362 are provided at both ends of the second guide cylinder 1332. The second spring 13372 is inserted into the second guide cylinder 1332, and two ends of the second spring 13372 are fixedly connected with the two second gaskets 13362 respectively. The second mounting bars 13382 are two, one ends of the second mounting bars are fixedly connected with the two second gaskets 13362 respectively, and the other ends of the second mounting bars extend out of the second guide cylinder 1332 through the through holes respectively.

A second slot into which the second mounting rod 13382 is inserted is provided in the first cover plate, and the second mounting rod 13382 can slide up and down along the second slot. The number of the support rods 1334 is two, one end of one support rod 1334 penetrates through the limiting hole to be fixedly connected with the side wall of one first gasket 13361, and the other end penetrates through the limiting hole to be fixedly connected with the side wall of one second gasket 13362. One end of the other support bar 1334 passes through the limiting hole and is fixedly connected with the side wall of the other first gasket 13361, and the other end of the other support bar 1334 passes through the limiting hole and is fixedly connected with the side wall of the other second gasket 13362. When the first guide cylinder 1331 and the second guide cylinder 1332 need to be detached from the first cover plate, the two support rods 1334 are driven to move towards each other by the hands of a human body, so that the two first gaskets 13361 are moved towards each other, and the two second gaskets 13362 are moved towards each other, so that the first springs 13371 and the second springs 13372 are compressed, and the first mounting rods 13381 are located in the first guide cylinder 1331, and the second mounting rods 13382 are located in the second guide cylinder 1332. At this time, the first guide cylinder 1331 and the first cover plate are separated from each other, and the second guide cylinder 1332 and the first cover plate are also separated from each other. The two support rods 1334 move toward each other, which in turn moves the two first shims 13361 toward each other, and the two second shims 13362 move toward each other, which in turn compresses the first and second springs 13371, 13372, which in turn positions the first mounting rod 13381 within the first guide cylinder 1331, and the second mounting rod 13382 within the second guide cylinder 1332. At this time, the first guide cylinder 1331 and the first cover plate are separated from each other, and the second guide cylinder 1332 and the first cover plate are also separated from each other.

Specifically, in the exemplary embodiment, the second tensioning device 123 is identical in structure to the first tensioning device 113, and the fine sandpaper 122 sequentially passes around the second transmission gear 121, the first guide cylinder 1331 of the second tensioning device 123, the second guide cylinder 1332 of the second tensioning device 123, and the third guide cylinder 1333 of the second tensioning device 123. When the fine abrasive paper 122 is used for a long time, the force of the restoring deformation of the tightening spring 1335 of the second tension adjuster 123 drives the supporting rod 1334 of the second tension adjuster 123 to move upwards, so as to drive the first guide cylinder 1331 of the second tension adjuster 123 and the second guide cylinder 1332 of the second tension adjuster 123 to move upwards, thereby enabling the fine abrasive paper 122 to be more tightly attached to each component.
