[0025] Specifically, by Figure 2-4The grinding mechanism 2 includes a left vertical plate 201 and a right vertical plate 202 symmetrically fixed to the top of the base 1. The left vertical plate 201 and the right vertical plate 202 are arranged parallel to each other. A left support shaft 2010 and a right support shaft 207 are rotatably connected to the sides of the left vertical plate 201 and the right vertical plate 202 that are close to each other, respectively. An abutment plate 2012 is fixedly installed on the outer side of the left support shaft 2010. Two U-shaped round rods 209 are symmetrically fixedly connected between the tops of the left vertical plate 201 and the right vertical plate 202. A sliding plate 208 is movably sleeved between the two U-shaped round rods 209. The bottom of the sliding plate 208... An adjusting cylinder 2018 is fixedly installed on the unit. A lifting plate 2015 is fixedly installed at the bottom of the adjusting cylinder 2018. A grinding motor 2017 is fixedly installed at the bottom of the lifting plate 2015. A grinding disc 2016 is fixedly connected to the grinding motor 2017. Two columns 2020 are symmetrically fixedly connected to the top of the lifting plate 2015. Both columns 2020 pass through the slide plate 208 and are movably connected to the slide plate 208. A drive motor 2011 is fixedly connected to the side of the left upright plate 201 near the right upright plate 202. A drive shaft 2 is fixedly connected to the drive motor 2011. 013, the drive shaft 2013 is located below the left support shaft 2010 and the right support shaft 207. Both the left and right support shafts 2010 and 207 are connected to the drive shaft 2013 via conveyor belts 2014. The end of the drive shaft 2013 away from the drive motor 2011 passes through the right vertical plate 202 and is fixedly connected to a drive bevel gear 203. A driven shaft 205 is rotatably connected to the top of the base 1. A driven bevel gear 204 is fixedly installed on the outside of the driven shaft 205. The driven bevel gear 204 meshes with the drive bevel gear 203. The top of the driven shaft 205... A top plate 206 is fixedly connected, and a movable rod 2019 is rotatably connected to the top of the top plate 206. The end of the movable rod 2019 away from the top plate 206 is rotatably connected to the top of the slide plate 208. A bracket 2022 is fixedly installed on the side of the right upright plate 202 away from the left upright plate 201. A support ring 2021 is fixedly installed on the top of the bracket 2022. A driven shaft 205 passes through the support ring 2021. Multiple bottom columns 2024 are fixedly connected at equal angles to the bottom of the top plate 206. Each bottom column 2024 has a ball bearing 2023 located at the top of the support ring 2021 at its bottom end.

[0026] In operation, the gas valve is first fixed between the left support shaft 2010 and the right support shaft 207. Then, the grinding motor 2017 is started, driving the grinding disc 2016 to rotate, and the adjusting cylinder 2018 is activated, causing the lifting disc 2015 to move downward. The stability of the lifting disc 2015 during movement is ensured by the cooperation between the column 2020 and the sliding plate 208. Simultaneously, the grinding disc 2016 descends to grind the gas valve. Then, the drive motor 2011 is started, driving the drive shaft 2013 to rotate, which is then conveyed by two conveyor belts 2014. The left support shaft 2010 and the right support shaft 207 rotate to realize the rotation of the gas valve. Since the driving bevel gear 203 is meshed with the driven bevel gear 204, it drives the driven shaft 205 to rotate and drives the top plate 206 to rotate. At the same time, each ball 2023 rolls on the top of the support ring 2021 to ensure the stability of the top plate 206 during rotation. Then, the sliding plate 208 is driven to slide along the two U-shaped round rods 209 through the movable rod 2019. At the same time, the polishing disc 2016 moves horizontally back and forth, and finally the gas valve is polished in all directions.

[0027] Specifically, by Figure 5 As shown, a fixing mechanism 3 is provided on the right support shaft 207. The fixing mechanism 3 includes a groove 301 opened on the right support shaft 207. A clamping cylinder 305 is fixedly installed in the groove 301. A side rod 302 is fixedly connected to the clamping cylinder 305. One end of the side rod 302 away from the clamping cylinder 305 extends to the outside of the groove 301 and is fixedly connected to a limit post 303. A limit plate 304 is fixedly installed on the outside of the limit post 303.

[0028] In use, first, the gas valve is placed on the outside of the left support shaft 2010 and abuts against the abutment plate 2012. Then, the clamping cylinder 305 is activated, which drives the side rod 302 to rotate and drives the limit post 303 to move and insert into the gas valve until the limit plate 304 abuts against the gas valve, and finally the gas valve is clamped and fixed.
