[0020] The lower clamping assembly 2 includes a first base 201, a sleeve rod 202, a hydraulic cylinder 203, a telescopic bar 204, a clamping plate 205 and a limit bar 206. The first base 201 is arranged above the inner side of the base plate 101, and the sleeve rod 202 is arranged on the top side of the first base 201. The inner side of the sleeve rod 202 is provided with a telescopic bar 204 connected to the output end of the hydraulic cylinder 203, and the inner side of the telescopic bar 204 is provided with a clamping plate 205, and limit bars 206 are arranged at both ends of the inner side of the clamping plate 205.

[0021] The sleeve rod 202 and the clamping plate 205 are both double-layer structures.

[0022] In this embodiment, when clamping is required, the hydraulic cylinder 203 on one side of the double-layer structure sleeve rod 202 is used to output power to drive the output end to operate. After the hydraulic cylinder 203 outputs power to drive the telescopic bar 204 to telescope, the clamping plate 205 at one end of the telescopic bar 204 cooperates with the upper limit bar 206 to effectively clamp the product to be clamped.

[0023] The bearing assembly 1 comprises a base plate 101 , an assembly disk 102 , a fixing frame 103 and a truncated cone drain seat 104 . The top side of the base plate 101 is bolted to the fixing frame 103 via the assembly disk 102 , and the top side of the fixing frame 103 is provided with a truncated cone drain seat 104 .

[0024] In this embodiment, when in use, the product to be processed is placed on the top side of the truncated cone drain seat 104 . Since the truncated cone drain seat 104 is a truncated cone drain structure, it is convenient to input waste materials onto the assembly tray 102 below the fixing frame 103 .

[0025] The lifting and grinding mechanism 3 includes a second base 301, a hydraulic telescopic frame 302, an upper base 303, a crossbeam 304, a driving motor 305, a winding frame 306, a limiting slide bar 307, a steel cable 308, a carrying plate 309, an electric rotating base 3010, a swing arm 3011, a pneumatic telescopic arm 3012, a rotating column 3013 and a grinding wheel 3014. The second base 301 is arranged above both ends of the base plate 101, and a hydraulic telescopic frame 302 is arranged above the second base 301, and the output end of the hydraulic telescopic frame 302 is connected to the upper base 303, and a crossbeam 304 is arranged on the top side of the upper base 303.

[0026] In this embodiment, when grinding is required, the hydraulic telescopic frame 302 on the second base 301 is used to output power to drive the output end to operate, and the hydraulic telescopic frame 302 outputs power to drive the beam 304 connected to the base 303 to drop to a suitable height.

[0027] A winding frame 306 connected to the output end of the driving motor 305 is arranged on the inner side of the cross beam 304 , and a steel cable 308 carrying a limit sliding rod 307 is wound around the winding frame 306 , and a carrying plate 309 is arranged below the steel cable 308 .

[0028] In this embodiment, when the beam 304 is lowered to a suitable height, the output power of the output end of the driving motor 305 is used to drive the output end to operate. The output end of the driving motor 305 drives the output transmission of the output end on the beam 304 and then drives the winding rack 306 to operate. After the winding rack 306 operates, the steel cable 308 cooperates with the carrying plate 309 to operate to a suitable height.

[0029] An electric rotating seat 3010 is arranged on the bottom side of the mounting plate 309 , and a swing arm 3011 for mounting a pneumatic telescopic arm 3012 is arranged below the electric rotating seat 3010 , a rotating column 3013 is arranged below one end of the pneumatic telescopic arm 3012 , and a grinding wheel 3014 is arranged at the output end of the rotating column 3013 .

[0030] In this embodiment, when the carrying plate 309 moves to a suitable height, the electric rotating seat 3010 is used to output power to drive the output end to operate, so that the pneumatic telescopic arm 3012 cooperates with the upper swing arm 3011 to adjust to achieve the effect of fixed circular operation. In this way, the output end of the rotating column 3013 drives the grinding wheel 3014 to further grind the product clamped and fixed by the clamping assembly 2 below.

[0031] The working principle of the ductile iron pipe socket grinding device is: when in use, the product to be processed is placed on the top side of the truncated cone drain seat 104. Since the truncated cone drain seat 104 is a truncated cone drain structure, it is convenient to input the waste into the assembly plate 102 below the fixed frame 103. When clamping is required, the hydraulic cylinder 203 on one side of the double-layer structure sleeve rod 202 is used to output power to drive the output end to operate. After the hydraulic cylinder 203 outputs power to drive the telescopic bar 204 to telescope, the clamping plate 205 at one end of the telescopic bar 204 cooperates with the upper limit bar 206 to effectively clamp the product to be clamped. When grinding is required, the hydraulic telescopic frame 302 on the second base 301 is used to output power to drive the output end to operate. The hydraulic telescopic frame 302 outputs power to drive the upper connecting base The beam 304 of the seat 303 is lowered to a suitable height. When the beam 304 is lowered to a suitable height, the output end of the driving motor 305 is used to output power to drive the output end to operate. The output end of the driving motor 305 drives the output transmission of the output end on the beam 304 and drives the winding rack 306 to operate. After the winding rack 306 operates, the steel cable 308 cooperates with the upper carrying plate 309 to operate to a suitable height. When the carrying plate 309 runs to a suitable height, the electric rotating seat 3010 is used to output power to drive the output end to operate, so that the pneumatic telescopic arm 3012 cooperates with the upper swing arm 3011 to adjust to achieve the effect of fixed circular operation, so that the output end of the rotating column 3013 drives the grinding wheel 3014 to further grind the product clamped and fixed by the clamping assembly 2 below.
