[0028] When ready for use, the base 11 is placed in a designated position, and then the operator places the hub material to be processed on the lower mold 17, and then the motor 13 is turned on to drive the threaded rod 14 to rotate, and the plate body 15 is connected to the threaded rod 14 through the connecting block. The rotation of the threaded rod 14 causes the plate body 15 to drive the upper mold 16 to perform low-pressure casting on the hub material to be processed. When the low-pressure casting is completed, the operator turns on the electric push rods 22 on both sides respectively, driving the grinding block 23 to be close to the hub material to be processed, and then the operator drives the gear 24 to rotate through the driving mechanism 25, and the gear 24 is meshed with the gear ring 21, and the gear ring 21 is driven to rotate on the base 11, so that the grinding block 23 is driven by the gear ring 21 to grind the surface of the hub material to be processed, and then the grinding is completed.

[0029] Embodiment 2

[0030] See also Figure 1-4 , based on the first embodiment, a dust collection function is added;

[0031] A dust suction assembly 3 is provided on the base 11, and the dust suction assembly 3 includes: a reciprocating threaded rod 31, fixedly connected to the output end of the servo motor 251, and the driving rod 252 is fixedly connected to the top of the reciprocating threaded rod 31; a connecting plate 32, threadedly connected to the outer wall of the reciprocating threaded rod 31, and slidably connected to the inner wall of the base 11; a shell 33, inserted into the discharge pipe 27; a connecting rod 34, fixedly connected to the bottom of the connecting plate 32; a pressure plate 35, fixedly connected to the bottom end of the connecting rod 34; a one-way valve 36, symmetrically arranged inside the discharge pipe 27; a protective shell 5 is fixedly connected to the top of the base 11; a collecting box 4 is fixedly connected to the outer wall of the base 11, and the discharge pipe 27 is inserted into the collecting box 4.

[0032] When the device is grinding, the output end of the servo motor 251 drives the reciprocating threaded rod 31 to rotate, thereby driving the driving rod 252 to rotate, and the grinding block 23 is driven to grind through the driving rod 252. At the same time, the rotation of the reciprocating threaded rod 31 drives the connecting plate 32 to move back and forth up and down, so that the connecting plate 32 drives the pressing plate 35 to move back and forth up and down through the connecting rod 34. Since the two one-way valves 36 only allow the end close to the collection shell 26 to flow to the end away from the collection shell 26, when the pressing plate 35 moves upward, the dust and other debris on the top of the base 11 is sucked into the collection shell 26 through the dust inlet hole, and the dust and other debris inside the collection shell 26 are sucked between the two one-way valves 36. When the pressing plate 35 moves downward, the debris between the two one-way valves 36 is squeezed and discharged to the outside of the device through the discharge pipe 27, so that the device is convenient for cleaning the debris inside the collection shell 26 and can remove the debris from the bottom. The dust and other debris that have not entered the dust inlet hole on the top of the seat 11 are vacuumed, which reduces the operator's cleaning of the collection shell 26 and the top of the base 11, thereby improving the practicability of the device; a protective shell 5 is fixedly connected to the top of the base 11, and the protective shell 5 can cover part of the outer wall of the gear 24 and the ring gear 21 to prevent the operator from accidentally touching the rotating gear 24 and the ring gear 21 when the device is in use and causing injury, thereby improving the safety of the device; a collection box 4 is fixedly connected to the outer wall of the base 11, and the collection box 4 can collect dust and other debris discharged from the discharge pipe 27, and then the operator collects the debris by opening the sealing cover on the top of the collection box 4, and at the same time, the pressure relief valve on the side of the collection box 4 is used to prevent the internal pressure from being too high, so that the operator does not need to collect through external devices, and can collect after the device is used, thereby improving the practicability of the device.
