Abstract

The utility model discloses a hand polisher with inflating grinding wheels, which can polish the surfaces of objects made of various materials. The utility model comprises a universal motor which drives an inflating polishing wheel by two-stage speed reduction. Because of the good elasticity of the polishing wheel, the vibration is small or no vibration can be felt in operation. The concave and convex parts can also be polished; according to the material requirement of polished objects, the polishing wheel can be randomly exchanged with abrasive belts with different materials and graininess. The hand polisher with inflating grinding wheels has the advantages that the polisher body is small, and the operation is safe and convenient. The hand polisher with inflating grinding wheels can be used for sanding, derusting and polishing of metal pieces and wooden pieces in departments of machines, shipbuilding, construction, etc.

Description

Hand polisher with inflating grinding wheel

The utility model is a kind of portable inflation wheel polisher that body surface can be polished, and it belongs to polishing mechanical.

In existing technology, portable polishing mechanical has portable grinder, and it is dimerous by motor and emery wheel.Because it does not have deceleration device, and the emery wheel poor flexibility.Vibration is strong when work.Labor strength is big, and emery wheel is easily cracked but also can not or have the position Ricoh of different foreign material bright among a small circle scraggly.The effect of polishing small size object is relatively poor.

The purpose of this utility model is to overcome the deficiency in the above-mentioned prior art, and vibration is little when a kind of work is provided, can polish rough and uneven in surface among a small circle or have different foreign material the position, polish the portable preferably inflation wheel polisher of small size object effect.

Formation of the present utility model is: mainly contain motor, transmission device, polishing wheel, emery cloth, power line, switch and shell and form.Motor is the universal motor of self-ventilation protection, adopts the E class B insulation.Inject insulating materials between armature stamping and the rotating shaft.Protection insulation as rotor.The trapezoidal copper bar of commutator.With the mica sheet is the insulation between plates medium.Form with the phenolic glass fiber plastic compacting.Brush adopts electrographite to make.Transmission device is a double reduction gear, and first order reduction box and electronic machine screw or rivet link together.Gear is a garden post helical gear.Make with structural alloy steel.Tooth portion handles through high frequency heat; Slow down with polyurethane casting type adhesive tape in the second level.Polishing wheel is for inflating the obedient emery cloth that different materials, granularity are arranged on rubber tire or solid rubber tire, the rubber tire.Shell adopts polycarbonate and aluminium alloy compacting to form.Switch is a hand-pushing fast shut-off automatic reset switch.Have snap action mechanism and self-locking device.To be two core Plastic-sheathed Cables, cable be equipped with cable cover(ing) entering the shell place with power line.

By the above-mentioned polishing machine that manufactures and designs, because its polishing wheel is inflated, therefore good springiness when operation, vibrates little or imperceptible vibration.Overcome the easily cracked disadvantage of abrasive machine emery wheel.The rough and uneven in surface position of size all can be polished.Again because the abrasive belt of different materials, granularity can be housed on the polishing wheel.Can be according to the material requirement of polished object body.Arbitrarily change abrasive belt.To reach satisfied requirement.This polishing machine volume is little.In light weight, easy to operate, safe and reliable.Can be widely used in sanding, rust cleaning, the polishing of the metalwork of departments such as machinery, shipbuilding, building, and the sanding of plank and large-scale woodenware spare.
