Detailed description of the invention
For the technical scheme that detailed explanation the utility model provides, be specifically addressed by reference to the accompanying drawings.
The present embodiment provides a kind of integral-type sander, is that the overall structure figure of sander comprises electricity as shown in Figure 1Machine structure, live-roller group, operation part; Electric machine structure is connected by motor shaft 4 with live-roller group; Driving gear set is logicalCross power transmission shaft 12 and connect operation part; Dust exhaust apparatus is positioned at the lower end of electric machine structure. .
In the sander course of work, motor 3 mechanical movements produce heat, produce vibration, motor in Machine Movement ProcessFront end in structure is equipped with the damping device 2 of high elastic rubber, can reduce the vibrations of motor. The motor shaft 4 of motor right-hand memberOn heat dissipation exhaust fan 5 is installed, the hot gas in the seal cavity of electric machine structure is arranged from the exhaust outlet 1 in the sander upper left cornerGo out.
The power that motor shaft 4 driving motors produce, drives dust suction ventilating fan to rotate, and now the velocity of rotation of motor shaft is very fast.Transmit the power of motor generation to the active variator rollers 7 of live-roller group through the motor shaft 4 of dust suction ventilating fan, drive topThe driven variator rollers of the radiuses such as concentric is rotated, and driven variator rollers 8 drives initiatively variator rollers of secondary by speed change connecting axle 910 rotate, and change the dynamic speed that motor produces, with the initiatively driven variator rollers of secondary of the radius such as variator rollers concentric of secondaryPower is passed to power transmission shaft 12 by 11 rotations.
Change through the effect of secondary variator rollers the power that the motor 3 in electric machine structure produces, through power transmission shaft 12 to operation groupPart provides power, drives the rotation of operation disk 17, and the material components that needs sand milling polishing is polished. As Fig. 2 instituteShow, in the middle of the sponge 17-2 of operation disk 17, cut out the circular sponge that radius is 15-20mm, along operation disk radial directionOn same circumference, be evenly provided with passage 17-3, interior outside is all coated with elastic caoutchouc skin 17-1, can alleviate operation diskVibrations in operation process, ensure steadily to carry out operation, ensure the effect of sand milling polishing. In the middle of operation disk, pass through bolt-typeScrew 16 is fixed on the low order end of power transmission shaft, and described fixed form can be changed operation disk, and cost is low.
Be the schematic diagram of seal closure as shown in Figure 3, seal closure 13 is that hollow radius is band radian and the edge of 35-40mmAnnulus, hollow design make operation disk in operation process because the air pressure of airtight generation obtains on average, reduce because of air pressure increaseTo the damage of seal closure. Seal closure is fixed on sander shell by four screw 13-2 of horizontal and vertical symmetry, asA point 13-1 on accompanying drawing 3 and B point, sealing cover is replaceable.
Fig. 4 is the plane of seal closure and operation disk, and while work, operation disk plane 18 is than the edge of seal closure 19 heightGo out coated India rubber layer outside sponge; When work, operation disk is compressed, between having between the edge of seal closure and materialGap, prevents object to produce cut.
Motor shaft as shown in Figure 1 connects dust suction ventilating fan 6, and dust suction ventilating fan is positioned at before live-roller group, without live-rollerGroup speed change, can meet the fast dust-contained airflow transition of the rate of filtration, and the active force of dust suction ventilating fan is inhaled sand by dust by spaceIn ray machine cavity, approach the position of dust discharge skirt, dust reduces dust air velocity by dust discharge skirt 14, finally collectionIn in laying dust bag 15, after sander work a period of time, can regularly change laying dust bag, ensure the suction of apparatusDirt effect. The length of dust discharge skirt is longer, and dust discharge skirt adopt alloy material make, can bear operator's palmGrip, the hand-held sander of operator in convenient working process, operation is more stable.
Finally should be noted that: above embodiment only in order to illustrate the application technical scheme but not to its protection domainRestriction, although the application is had been described in detail with reference to above-described embodiment, those of ordinary skill in the field shouldUnderstand: those skilled in the art still can carry out all changes, repair the detailed description of the invention of application after reading the applicationChange or be equal to replacement, but these change, revise or be equal to replacement, the claim protection domain all awaiting the reply in applicationWithin.
