Abstract

The utility model relates to a portable electric polishing machine belonging to the polishing mechanical equipment for wall surface, which aims to provide the portable electric polishing machine with lighter weight, simple assembly, convenient use and reliable performance. The utility model adopts the technical proposal that a pit is formed on the top part of a dust cover, a first gear shaft and a secondary gear shaft which are meshed are arranged in the pit, an axial spring cavity and a radial pin hole are formed on the bottom part of the secondary gear shaft, a long slotted hole is formed radially on the upper part of the connecting shaft, a threaded sleeve is formed on the bottom part thereof, the upper part of the connecting shaft is inserted into the spring cavity of the secondary gear shaft to touch a spring, a pin penetrates through the pin hole and the long slotted hole, and a screw on the top part of a polishing disc is mounted in the threaded sleeve of the connecting shaft in a rotating way. The utility model has the advantages that the polishing disc is directly mounted inside the dust cover, no base plates are arranged, the weight of the entire machine can be reduced, and the troublesome base plate adjustment can be avoided; the polishing disc is elastically connected with the secondary gear shaft and can extend and retract freely, thereby the utility model is suitable for different polishing circumstance and can be applied to polishing wall surface or ground surface.

Description

The portable electric sanding machine

Technical field:

The utility model relates to the polishing plant equipment, is particularly suitable for the portable electric sanding machine of metope or floor surface polishing.

Background technology:

The applicant had once applied for a kind of portable electric sanding machine patent, open day is on July 16th, 2008, the patent No. is 200720183885.9, this technical scheme is that motor passes through double reduction tooth axle and is connected with mill, and dust cover is installed on motor bottom by screw, and the dust cover top is provided with a dust suction interface, the side is provided with an adjustable air inlet, the chassis of built-in mill is installed in the dust cover by four bolts, and every bolt is with spring, regulates the horizontal level on chassis by nut.Above-mentioned sanding machine remains in following shortcoming: 1, the chassis is connected with dust cover by the screw that is with spring, the assembling trouble, and complete machine weight is heavier relatively; The position on 2 chassis is regulated by four nuts, and relatively more tired lock operates; Mill is connected firmly with electric machine main shaft, and running into matsurface needs mobile complete machine, uses harder; 3, the dust suction interface is installed on the top of dust cover, the easy block vision of sweep-up pipe, and move to sanding machine and to make troubles; 4, dust cover only is provided with an adjustable air inlet, often needs to suck more air, and an air inlet can't satisfy.

The utility model content:

The purpose of this utility model provides that a kind of weight is light, assembling is simple, easy to use, the portable electric sanding machine of dependable performance.

The technical solution of the utility model is: comprise that motor, dust cover, bottom post the mill of sand paper, the top of dust cover is shaped on pit, place one-level tooth axle and the secondary tooth axle that is meshed in the pit, one-level tooth axle is connected with electric machine main shaft, mill is installed in the dust cover, secondary tooth axle bottom is shaped on axle spring chamber and pin-and-hole radially, connecting axle top radially is shaped on long slot bore, the bottom is shaped on swivel nut, secondary tooth axle spring cavity is inserted on the top of connecting axle and spring touches, pin runs through pin-and-hole and long slot bore, and the screw threads on mill top is loaded in the swivel nut of connecting axle.

The sidewall of dust cover is shaped on dust suction interface and air regulating port, and the dust suction interface is positioned at motor handle below, and adjusting knob is plugged in the air regulating port.The roof of dust cover is shaped on air inlet.

The utility model has the advantages that: mill directly is installed in the dust cover, and no chassis is provided with, and can alleviate complete machine weight, avoids the chassis of tired lock to regulate; Mill is connected with secondary tooth axle elasticity, and the mill retractable adapts to different polishing environment; The dust suction interface is installed on the sidewall of dust cover, and is little to the moving influence of complete machine; Roof at dust cover increases air inlet, air intake better effects if again.

Fig. 2 is the utility model bottom cutaway view.

Fig. 3 is the utility model installation diagram.

The specific embodiment:

With reference to Fig. 1 and Fig. 3, the utility model comprises motor 1, dust cover 4, mill 14, sand paper 15, and wherein dust cover 4 is a bowl-shape shape and Open Side Down is provided with, and sand paper 15 sticks on the bottom surface of mill 14 and is positioned in the dust cover 4.Dust cover 4 tops are shaped on three grades of stepped pits, and pit bottom is shaped on through hole, and motor 1 bottom is installed on going up of dust cover pit by four screws 16 and cheats, and increases both steadiness.Motor 1 outer wall is provided with handle, and handle is equipped with power switch, and external cord is by being connected with motor, external dust catcher behind the power switch, and this power switch can be controlled power supply of the present utility model and reach the dust catcher power supply that is connected with the utility model.Dust cover 4 roofs are shaped on air inlet 8, dust cover 4 sidewalls are shaped on dust suction interface 5 and air regulating port 6, adjusting knob 7 is plugged in the air regulating port 6, and dust suction interface 5 is positioned at the below of motor 1 handle, the sweep-up pipe that is installed on dust suction interface 5 along handle move use more convenient.

Motor 1 main shaft and one-level tooth axle 2 tops are connected, secondary tooth axle 3 middle parts are installed with gear 9 and bearing 17, the gear 9 of the bottom of one-level tooth axle 2 and secondary tooth axle 3 slows down and meshes, two engagement positions are positioned over the middle hole of pit, bearing 17 is positioned at the bottom of the hole of pit, and the through hole of pit is run through in secondary tooth axle 3 bottoms.Secondary tooth axle 3 bottoms are cylindrical shape, are spring cavity in the tube, and spring 12 is positioned in the spring cavity, and barrel radially is shaped on pin-and-hole 3a.The top of connecting axle 10 radially is shaped on long slot bore 10a, and the bottom is a swivel nut, and screw 13 spiral shells on connecting axle 10 bottoms and mill 14 tops connect.Secondary tooth axle 3 spring cavitys and spring 12 touchings are inserted in connecting axle 10 tops, and pin 11 runs through pin-and-hole 3a and with long slot bore 10a both is connected; Pin 11 can be movable in long slot bore 10a, and mill 14 axially moves under the effect of spring 12 and metope pressure.

Mill 14 is connected with two-stage tooth axle elasticity, and when running into uneven metope, mill 14 relative complete machines freely stretch, and need not Artificial Control.Dust cover 4 bottoms do not have the chassis and are provided with, and avoid the assembling and the adjusting of tired lock, complete machine weight saving, and cost reduces.Auxiliary air inlet 8 air intakes of air regulating port 6 when the intake of air inlet 8 is not enough, are opened air regulating port 6, adapt to the working environment of different amount of dust.
