Dust suction type casting float polishing mechanism

Abstract

The invention discloses a dust suction type casting float polishing mechanism. The dust suction type casting float polishing mechanism comprises a base, a feeding mechanism, a gag bit, a movable plate, an elastic mechanism, a first guide rod, a guide sleeve, a rotating shaft base, a motor, a rotating shaft, a grinding wheel, a first nitrogen spring and a dust sucking mechanism; the feeding mechanism works to drive the grinding wheel to move; after the grinding wheel is contacted with castings, the motor drives the grinding wheel to rotate through the rotating shaft so as to polish the castings; the dust sucking mechanism collects and discharges waste chips and smoke generated during polishing; and when the feeding mechanism performs a feeding motion, the guide sleeve moves along the firstguide rod by a micro distance, and is kept balanced to guarantee always tight contact between the grinding wheel and the castings, and meanwhile, the grinding wheel or the castings cannot be damaged.The device is simple in structure; the elastic mechanism enables the movable plate to locate in a floating state, so that the impact caused by the feeding motion is effectively balanced, the polishingeffect is improved, and the damage of the grinding wheel or the castings is effectively prevented; and the waste chips and the smoke generated during polishing can be collected and discharged to effectively purify the working environment.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a dust suction floating grinding mechanism for castings. Background technique [0002] After the casting is poured, there will be a lot of flashes and risers on the surface. These flashes and risers must be removed. For iron castings, they are generally knocked off directly with an oil hammer, while steel castings need to be cut off by gas cutting. Then use the casting grinder to polish the excess flash and pouring riser on the casting to make it smooth and beautiful. At present, electric grinding machines are generally used for grinding. There are fixed large grinding wheel diameter grinding machines and hand-held movable small grinding wheel diameter grinding machines. When it is large, it is easy to cause damage to the grinding wheel or the casting. Moreover, during manual grinding, the environment of the grinding site is harsh, which affects the health of the grinder. In view of the a...

At present, electric grinding machines are generally used for grinding. There are fixed large grinding wheel diameter grinding machines and hand-held movable small grinding wheel diameter grinding machines. When it is large, it is easy to cause damage to the grinding wheel or the casting. Moreover, when manual grinding is performed, the environment of the grinding site is harsh, which affects the health of the grinder.
