A small gear 205 is fixedly installed on the outside of each support shaft 2015, and each small gear 205 meshes with the large gear 207. A top ring 2033 is fixedly connected to the top of the top plate 2010. An annular groove 2034 is provided on the inner side of the top ring 2033. A movable... The moving ring 2036 and the movable ring 2036 are rotatably connected to the top ring 2033 via an annular groove 2034. A movable cylinder 2032 is fixedly sleeved inside the movable ring 2036 and movably sleeved on the outside of the rotating shaft 209. Multiple support columns 2038 are fixedly connected at equal angles to the bottom of the movable cylinder 2032. Each support column 2038 has a ball bearing 2035 mounted at its bottom end on the top of the top plate 2010. When the movable cylinder 2032 rotates, it drives each ball bearing 2035 to roll on the top of the top plate 2010, ensuring the stability of the movable cylinder 2032 during rotation. A conveyor belt 2029 is connected between the movable cylinder 2032 and the drive shaft 208. Two side grooves 2030 are symmetrically provided on the outside of the rotating shaft 209.Two inner blocks 2037 are symmetrically fixedly connected to the inner side of the movable cylinder 2032. The two inner blocks 2037 are slidably connected to two side grooves 2030 respectively. A fixed plate 2023 is fixedly connected to the top of the base 1. The fixed plate 2023 passes through the L-shaped plate 203. A drive shaft 2024 is rotatably connected to the side of the fixed plate 2023 near the vertical plate 2013. The end of the drive shaft 2024 away from the fixed plate 2023 passes through the vertical plate 2013 and is fixedly connected to a turntable 2026. The drive shaft 2024 is rotatably connected to the vertical plate 2013. A drive mechanism is fixedly installed on the outer side of the drive shaft 2024. A driven shaft 2022 is rotatably connected to the side of the vertical plate 2013 away from the turntable 2026, with a driven gear 2025. A bevel gear 2019 is fixedly connected to the end of the driven shaft 2022 away from the vertical plate 2013. A bevel gear 2020 is fixedly installed on the outer side of the column 201, meshing with the bevel gear 2019. The driven shaft 2022 passes through the fixed plate 2023 and is rotatably connected to it. A driven gear 2021 is fixedly installed on the outer side of the driven shaft 2022, meshing with the drive gear 2025.

[0035] First, multiple workpieces are placed and fixed in their respective placement cylinders 2012. Then, the turntable 2026 is rotated, causing the drive shaft 2024 to rotate, which in turn drives the drive gear 2025 to rotate. Since the drive gear 2025 meshes with the driven gear 2021, it drives the driven shaft 2022 to rotate. Since bevel gear 1 2019 meshes with bevel gear 2020, it drives the column 201 to rotate, which in turn drives the top plate 204 to rotate. Then, the support plate 2014 is rotated through the L-shaped round rods 2017 until one of the placement cylinders 2012 is directly below the grinding disc 2027. Then, the motor 206 is started, driving the transmission shaft 208 to rotate, which in turn drives the bracket 2011 to rotate. Since each pinion 205 is engaged with... The large gear 207 meshes and connects, thereby driving the rotation of each support shaft 2015 and each placement cylinder 2012, realizing the rotation of each workpiece. Since the movable ring 2036 is rotatably connected to the top ring 2033 through the annular groove 2034, it drives the movable cylinder 2032 to rotate through the conveyor belt 2029, and drives the rotating shaft 209 to rotate through the cooperation between the inner block 2037 and the side groove 2030. Then, it drives the grinding disc 2027 to rotate through the mounting disc 2028. The grinding disc 2027 rotates in the opposite direction to the workpiece, so when the grinding disc 2027 descends, it polishes and grinds the workpiece below it. Since the support disc 2014 can drive each placement cylinder 2012 to rotate circumferentially, the multi-station grinding work is finally completed.

[0036] In Embodiment 3, based on Embodiment 1, the lifting mechanism 3 includes a side plate 301 fixed to the side of the upright plate 2013 away from the top plate 2010.

Two connecting rods 304 are symmetrically fixedly connected between the lifting plate 303 and the lifting plate 2031. A side plate 302 is fixedly sleeved on the outside of the U-shaped rod 306 between the lifting plate 303 and the side plate 301. The side plate 302 is fixed to the upright plate 2013. A cylinder 305 is fixedly installed between the side plate 302 and the lifting plate 303.

[0037] First, start cylinder 305, which drives lifting plate 203 to slide down along U-shaped rod 306, and then drives lifting plate 2031 to move down through two connecting rods 304. Then, the rotating grinding disc 2027 is driven down through rotating shaft 209 and mounting plate 2028, and finally the workpiece is polished and ground.

[0038] In Example 4, based on Example 1, the limiting mechanism 4 includes a sliding plate 401 movably sleeved on the outside of the U-shaped rod 306. The sliding plate 401 is located between the side plate 302 and the side plate 301. Two springs 4011 are symmetrically fixedly connected between the sliding plate 401 and the side plate 302. Both springs 4011 are sleeved on the outside of the U-shaped rod 306. A U-shaped rod 4010 is fixedly connected to the bottom of the sliding plate 401. The U-shaped rod 4010 passes through the side plate 301 and is movably connected to it. A sleeve plate 409 is fixedly sleeved on the middle of the outer side of the U-shaped rod 4010. A through groove 407 is provided on the upright plate 2013. The sleeve plate 409 is slidably connected to the through groove 407. A locking gear 408 located directly above the drive gear 2025 is fixedly connected to the bottom of the sleeve plate 409. The locking gear 408 is in contact with the drive gear 2025. The side panel 301 is fixedly connected to a U-shaped rod 403 on the side away from the upright plate 2013. A sliding plate 404 is movably sleeved on the outside of the U-shaped rod 403. Two movable rods 406 are symmetrically rotatably connected to the bottom of the sliding plate 404.

The limiting post 405 passes through the upright plate 2013 and is movably connected to the upright plate 2013. Multiple limiting cylinders 2016 are fixedly connected at equal angles to the bottom of the support plate 2014. The inner diameter of each limiting cylinder 2016 is equal to the outer diameter of the limiting post 405. The bottom of the sliding plate 401 is provided with a slot 4012. The top of the side panel 301 is rotatably connected with an insert plate 402. The insert plate 402 is set perpendicular to the side panel 301 and is inserted into the slot 4012.

[0039] In the initial state, the insert plate 402 is inserted into the slot 4012, providing support for the slide plate 401, while both springs 4011 are compressed. First, the slide plate 401 is slid upwards along the U-shaped rod 306, compressing the two springs 4011 again until the insert plate 402 is removed from the slot 4012. Then, the insert plate 402 is rotated to a horizontal position at the top of the side plate 301, and the slide plate 401 is released. At this point, both springs 4011 return to their original positions, causing the slide plate 401 to slide downwards along the U-shaped rod 306. The U-shaped round rod 4010 drives the sleeve 409 to move downward along the through groove 407, and drives the locking gear 408 to descend. At the same time, the two movable rods 406 drive the slide plate 404 to slide along the U-shaped round rod 403 and approach the side plate 301. Then, the limiting post 405 moves horizontally and inserts into the corresponding limiting cylinder 2016 to limit the support plate 2014 until the locking gear 408 meshes with the drive gear 2025 to limit the drive shaft 2024. Finally, it prevents the placement cylinder 2012 from rotating arbitrarily and affecting the grinding effect on the workpiece.
