Abstract

The utility model relates to an air-inflation polisher, which is a tool used for carrying out polishing to metal, wood, etc., and is composed of a motor and a grinding drum wheel, wherein, the grinding drum wheel is also composed of an H-shaped mould, a rubber air bag, an abrasive cloth belt, etc.; the abrasive cloth belt is sheathed outside the rubber air bag. When the utility model is used, the interior of the rubber air bag is inflated. Because the inflated grinding drum wheel has better elasticity and toughness, and thus, the utility model is very suitable for the polishing of irregular curved faces. Labor intensity is reduced. Labor productivity is increased. The defects of the inconvenient replacing and the large waste of polishing materials of the conventional polishing machines are overcome.

Description

Inflated polishing machine

The utility model relates to a kind of machining equipment, specifically a kind of instrument that is used for grindings such as metal, timber, polishing.

Generally all be to polish at the used polishing apparatus of industries such as machinery, woodenware at present by the rotation of abrasive materials such as motor drives emery wheel, fabric disc, grinding wheel, these apparatuses only limit to plane or rotary surface polishing, polishing is subjected to very big restriction for curved surface, particularly do not plan curved surface, some parts as furniture, often can only manually polish with sand paper, labour intensity is big, and efficient is low; Its abrasive material can not exhaust and must change, and causes very big waste, and the replacing of abrasive material bothers.The operation of this class instrument requires also higher, and inconvenience is grasped.Though the wheeled abrasive belt of belt can be used for the curved surface polishing, because its contact-making surface is little, poor in flexibility, effect is undesirable.

The purpose of this utility model is to provide a kind of can carry out the curved surface polishing neatly, and the replacing abrasive material makes things convenient for, manipulates simple electric polishing machine.

The utility model mainly is made up of motor and abrasive drum wheel, grinds drum and is fixed on the motor reel.Wherein grinding drum is made of mold, rubber inflatable bag and abrasive material three parts again.Abrasive material is cylindric abrasive belt, is placed in the rubber inflatable bag outside, and rubber inflatable bag is enclosed within on the mold, there is charge valve the air bag outside, can inflate in bag, the inflation back is fixed on abrasive belt on the rubber inflatable bag firmly owing to the tension force effect, venting back replaceable sand strap.By changing polishing or other purposes that different abrasive materials can be used for metal, timber.

Grinding drum can have two, diameter small one and large one, be separately fixed on the axle of motor both sides.

The utility model adopts inflatable to grind drum, favorable elasticity and pliability is arranged, and can how much change its elasticity and toughness by aeration quantity, therefore very is suitable for the polishing of irregular curved surface, has reduced labour intensity, has improved labor productivity; Its columnar abrasive belt is an abrasive material, and dismounting is all very convenient, and the abrasive material utilization is abundant, only changes different abrasive belts and just can be used for different occasions; Be used in and can be used as desk-top or portable sanding machine on the dissimilar motors, use flexible operation easy.It also has cheap, safe and reliable advantage simultaneously.

The utility model is described in further detail below in conjunction with drawings and Examples.

The utility model both can have been made fixed, also can make portablely, and Fig. 1 has represented a kind of embodiment of fixed inflated polishing machine.Wherein, mold 9 is two circular flange dishes that linked together by hollow bushing 15, be " worker " font, rubber inflatable bag 11 is enclosed within on the mold 9, respectively the both ends of the surface of outward flange dish 7 and inner flange 13 and mold 9 are tightened up with bolt 8, rubber inflatable bag 11 is clamped between ring flange and the I-shaped mold, reaches the purpose of sealing.Have air-filled pore 6 on the ring flange 7 outside, have air-filled pore 10 on the outer face of mold 9.The whole grinding drum 2 that installs is enclosed within on the motor central shaft 3 by central through hole 14, and the top is fastening with nut 4.After this abrasive material 12 is placed in outside the rubber inflatable bag 11, inflates to rubber inflatable bag 11 in by air-filled

pore

6,10 from charge valve 5, owing to the tension force effect with abrasive material 12 swellings on rubber inflatable bag 11.Starting motor 1. can polish.By the elasticity size that how much can change drum of inflation, to satisfy different needs.Can change abrasive material 12 easily after the venting.Rubber inflatable bag 11 is the garden column, has circular hole with the corresponding position of ring flange on its both ends of the surface, and abrasive material 12 is a cylindrical shape abrasive belt; After rubber inflatable bag 11 is enclosed within on the mold 9, compress with outward flange dish 7 and inner flange 13 again, closely fixing by bolt 8.Have air-filled pore 10 on garden, the outer end dish of mold 9, have air-filled pore 6 on the outward flange dish 7, this air-filled pore 6 links to each other with charge valve 5.On the central shaft in motor left side the grinding drum identical with the right side structure is housed also, just diameter is smaller relatively, does not draw among Fig. 1.As if being contained on the hand held, electric machine, grinding drum 2 can become portable inflated polishing machine.

Design of the present utility model not only is confined to sanding machine, can make various forms to mold and rubber inflatable bag as required, as adopt conical mold and corresponding airbag, abrasive material is changed to suitable material, then can be used on the shoe-cleaning machine: adopt the worm and gear transmission, and add large volume, also can be used to wash the floor, or the like.
