Abstract
The utility model relates to an electric sand polisher, particularly a fine grinding self-sucking type sand polisher. A fission type small power series motor which is adopted by the existing flat plate dust sucking sand polisher with a self-locking switch is modified into an integral type large power series motor by the fine grinding self-sucking type sand polisher. A blade eccentric wheel is used for substituting a blade and an eccentric block, and a round work bottom plate is used for substituting a rectangular work bottom plate. The fine grinding self-sucking type sand polisher not only has the functions of quick polishing and quick sucking dust, but also has the function of dust self-sucking; meanwhile, the fine grinding self-sucking type sand polisher has the advantages of large power, low noise, small volume, light weight, good fine grinding effect, etc. The fine grinding self-sucking type sand polisher is suitable for being used under various sand polishing environment.
Description
The utility model relates to a kind of electric sander, the self-priming sander of particularly a kind of correct grinding.
The utility model is the applicant proposes " the dull and stereotyped dust suction sander of band self-lock switch " patent application (92218521.2) on August 15th, 1992 continuation and development.
Though it is flexible that the dull and stereotyped sander of existing band self-lock switch has startup and shutdown, the casing tightness is good, fast dust-removing under extraneous vacuum cleaner booster action, and around the reduction sander and advantage such as inner dust residual quantity, but also have following problem: 1. the stator and rotor of series excitation type motor are split type, be difficult for guaranteeing that noise is big, poor work stability by the dress precision.2. vibrate the complex structure of eccentric, the cost height.3. the working plate face is a rectangle, can only be reciprocating, and the correct grinding weak effect.4. series excitation type electric electromechanics power is little, inefficiency.5. the necessary and vacuum cleaner auxiliary work of existing sander, its dust suction effect of competence exertion brings many inconvenience to operating process like this.
The purpose of this utility model is the self-priming dull and stereotyped sander of a kind of correct grinding that provides for the shortcoming that overcomes prior art.It has not only kept the advantage of prior art, and has the function of self-priming dust, has simultaneously that power is big, noise is low, volume is little, in light weight a, advantage such as correct grinding is effective, and it is adapted at use various sanding environment under.
According to the self-priming dull and stereotyped sander of the correct grinding that the utility model proposes, it mainly comprises the casing of being with handle, the series excitation type motor, cooling fan blade, working plate, sand paper, the sweep-up pipe of band air suction opening, self-locking power switch and casing trip bolt, the electrical power that it is characterized in that the series excitation type motor is 180~250W, its stator and rotor and front and rear cover are fixedly connected into integrated support structure, the lower end of this series excitation type motor main shaft connects a fan blade eccentric wheel, in the eccentric race of fan blade rolling bearing is housed, rolling bearing is fixed by jump ring, the fan blade eccentric wheel is fixedlyed connected with a connector by this rolling bearing with working plate, working plate is a circular bottom plate, has a storage dirt bag is set on the sweep-up pipe of air suction opening.Operation principle of the present utility model is: when the utility model with after external power source is connected, the operator grasps handle promptly enters the preparation state, because the resilience release knob of self-lock switch is arranged on casing handle bottom, the operator only needs to carry on gently with the grip of a finger, the resilience release knob can make the utility model connect power supply and enter duty, when the series excitation type motor main shaft of rotation drives the fan blade eccentric wheel high-speed rotation with eccentric structure at a high speed, the dust that the attraction that the fan blade eccentric wheel is produced is enough to produce when this machine work is drained into by the sweep-up pipe that has air suction opening and stores up in the dirt bag, this fan blade eccentric wheel passes through rolling bearing simultaneously, be connected with circular working plate with connector, make circular motion to reach the purpose of workpiece correct grinding sanding thereby make the fan blade eccentric wheel that rotates at a high speed drive circular working plate.
The utility model compared with prior art, its remarkable advantage is: 1. the stator and rotor of series excitation type motor are monoblock type, guaranteed by the dress precision, the complete machine noise is obviously reduced, job stability obviously improves.2. owing to adopted the fan blade eccentric wheel of compact conformation, thereby reduce volume and weight of the present utility model, reduced cost.3. working plate adopts circular working face, helps the circular motion that the utility model is made rule, has improved the correct grinding effect to workpiece.4. increase the electrical power of series-wound motor, thereby improved operating efficiency of the present utility model.5. have automatic dust-collection function, make the not residual dust in the utility model sander inside, saved outside supporting vacuum cleaner simultaneously, easy to operate.The utility model is suitable for using under the various sanding environmental conditions.
Concrete structure of the present utility model is provided by the following drawings and embodiment.
Accompanying drawing is the structural profile schematic diagram according to the self-priming dull and stereotyped sander of correct grinding that the utility model proposes.
Below in conjunction with accompanying drawing the utility model is described in further detail.
In conjunction with the accompanying drawings, the utility model mainly is made up of parts such as the casing 1 of band handle, the eccentric rolling bearing of being made up of drive end bearing bracket 2, main shaft 3, carbon brush 4, rotor 5, stator 6, motor rolling bearing 7 and rear end cap 8 11 of monoblock type series-wound motor, cooling fan blade 9, fan blade eccentric wheel 10, fan blade, jump ring 12, connector 13, working plate 14, sand paper 15, self-priming apparatus 16, self-locking power switches 17.Wherein the performance of self-locking power switch 17 is identical with the specification requirement of the dull and stereotyped sander of existing band self-lock switch with the assembling mode.The electrical power of monoblock type series-wound motor of the present utility model is 180~250W, usually it is good selecting 200W for use, it is by drive end bearing bracket 2, main shaft 3, carbon brush 4, rotor 5, stator 6, motor rolling bearing 7 and rear end cap 8 are formed, the bottom of monoblock type series-wound motor main shaft 3 is had the cooling fan blade 9 of 29 road wind grooves by interference fit, fan blade eccentric wheel 10 inside grooves are located the eccentric rolling bearing 11 of fan blades with jump ring 2, again by interference fit connector 13, connector 13 is made by ferrous based powder metallurgical, then the lower end of fan blade eccentric wheel 10 parts with monoblock type series-wound motor main shaft 2 is threaded, the monoblock type series-wound motor that will be assembled into more directly is assemblied in the motor location groove of casing 1, with screw that circular working plate 14 is fixing with connector 13 then, stick sand paper 15, circular working plate 14 is to make matrix and inserts and conjunction by rubber to be composited, its diameter is 120~180mm, usually it is good selecting φ 125mm for use, self-priming apparatus 16 is made up of the sweep-up pipe and the storage dirt bag of band air suction opening, be assemblied in the handle bottom of casing, to realize the purpose of automatic dust absorption.
The utility model has been obtained satisfied effect through validation trial.
