Description

Technical Field

[0001] The utility model relates to the technical field of manhole cover production, in particular to a grinding wheel machine for processing and grinding manhole covers. Background Art

[0002] Manhole covers are used to cover deep wells on roads or in homes to prevent people or objects from falling. They can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. according to the material. They are generally round. They can be used in green belts, sidewalks, motorway lanes, docks, alleys, etc.

[0003] At present, after the casting of stainless steel manhole covers is completed, many burrs and protrusions will remain on the outer surface, and the outer surface of the manhole cover needs to be polished by a grinder. Since the outer surface of the manhole cover is round, the existing grinder fixes the manhole cover during the grinding process of the top of the manhole cover and then grinds the top of the manhole cover by reciprocating the grinder. This reciprocating grinder method of grinding the manhole cover can easily grind the same area back and forth, resulting in uneven grinding. Utility Model Content

During the rotation of the manhole cover body 4, the first motor 10 is started to drive the first screw rod 9 to rotate, so that the slider 8 can be driven to slide from one side of the movable frame 7 to the other side. During the sliding process, the grinder body 11 will be driven to slide from one side of the manhole cover body 4 to the other side to grind the manhole cover body 4. The unidirectional propulsion can avoid the occurrence of uneven grinding due to grinding one area during the reciprocating grinding process.

[0028] The effect achieved by the entire embodiment 2 is that before grinding the manhole cover body 4, the second motor 13 is started to drive the second screw 12 to rotate, driving the movable frame 7 to move up and down, thereby changing the relative distance between the grinder body 11 and the manhole cover body 4, and playing a regulating role. When the turntable 3 rotates, the mutual engagement of the retaining ring 18 and the annular groove 17 can support the weight on the turntable 3, offset the axial force acting on the third motor 15, and protect the third motor 15.

During the rotation of the manhole cover body 4, the first motor 10 is started to drive the first screw rod 9 to rotate, so that the slider 8 can be driven to slide from one side of the movable frame 7 to the other side. During the sliding process, the grinder body 11 will be driven to slide from one side of the manhole cover body 4 to the other side to grind the manhole cover body 4. The unidirectional propulsion can avoid the manhole cover body 4 from rotating in the other direction. Grinding one area during the repeated grinding process leads to uneven grinding. Before grinding the manhole cover body 4, the second motor 13 is started to drive the second screw 12 to rotate, driving the movable frame 7 to move up and down, thereby changing the relative distance between the grinder body 11 and the manhole cover body 4 to play a regulating role.

At the same time, during the rotation process, by arranging the ball 20 between the opposite sides of the two raceways 19, the friction of the contact surface can be reduced, which facilitates the rotation of the turntable 3.
