Object of the present invention is exactly provide that a kind of structure is simple, volume is little, convenient maintenance and replacement, cost are low, the hand electric polisher of fast changeable grinding roller to overcome defect that above-mentioned prior art exists.This sanding machine is that dual-handle grips, and make parts add stress equalization in man-hour, polishing efficiency is higher, greatly reduce labor intensity of operating staff, and according to the difference that polished surface requires during on-the-spot processing grinding, can quick-replaceable grinding roller, thus be adapted to different operating occasion.

Object of the present invention can be achieved through the following technical solutions:

A kind of hand electric polisher, comprise grinding roller, drive the motor that grinding roller rotates and the shaft coupling be connected with motor by grinding roller, described sanding machine also comprises first handle, second handle and bearing with spherical outside surface, the inner ring of described bearing with spherical outside surface is set in the two ends of grinding roller, the outer ring matrix of bearing with spherical outside surface is connected with first handle or second handle, described first handle and second handle are the housing of inner hollow, described motor and shaft coupling are all positioned at first handle inside, and described motor is connected to one end of grinding roller by shaft coupling.

Described bearing with spherical outside surface is bearing with spherical outside surface of usheing to seat.

Described grinding roller is notch cuttype cylindrical roll, and middle is polishing section, and two ends are the linkage section for being connected with bearing with spherical outside surface.

Be bolted between the outer ring matrix of described bearing with spherical outside surface and first handle or second handle.

Be fastenedly connected by jackscrew between described bearing with spherical outside surface and grinding roller.

Described jackscrew is located on the inner ring of bearing with spherical outside surface.

The power switch of described motor is located at the outside of first handle.

Described first handle and second handle are cylindrical.

Compared with prior art, the present invention has the following advantages and beneficial effect:

One, the present invention is provided with two handles, operating personnel can be gripped by both hands respectively, parts polished surface stress equalization, polishing efficiency and precision are improved all greatly, greatly reduce the labour intensity of operating personnel, these two handles serve as the effect of casing in sanding machine simultaneously simultaneously.

Two, the grinding roller in the present invention can according to different component surface processing request, and quick-replaceable becomes different model, can adapt to multiplex polishing occasion, and by the jackscrew on degree of tightness bearing with spherical outside surface inner ring, when deenergization, can join fast and change grinding roller, improve polishing efficiency.

Three, structure of the present invention is simple, and volume is little, is convenient for carrying and uses, and outward appearance exquisiteness is attractive in appearance, and cost is low.

Number in the figure: 1. power switch, 2. first handle, 3. motor, 4. shaft coupling, 5. the first bearing with spherical outside surface, 6. bolt, 7. the first jackscrew, 8. grinding roller, 9. the second jackscrew, 10. the second bearing with spherical outside surface, 11. second handles.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

Embodiment

A kind of hand electric polisher, as depicted in figs. 1 and 2, comprises grinding roller 8, motor 3, shaft coupling 4, first handle 2, second handle 11, first bearing with spherical outside surface 5 and the second bearing with spherical outside surface 10.Wherein, grinding roller 8 is notch cuttype cylindrical roll, and middle is polishing section, and two ends are the linkage section for being connected with bearing with spherical outside surface.First bearing with spherical outside surface 5 and the second bearing with spherical outside surface 10 are bearing with spherical outside surface of usheing to seat.The inner ring of the first bearing with spherical outside surface 5 and the second bearing with spherical outside surface 10 is set on the linkage section of grinding roller 8 respectively, being fastenedly connected by being located at the first jackscrew 7 on the first bearing with spherical outside surface 5 inner ring between first bearing with spherical outside surface 5 and grinding roller 8, being fastenedly connected by being located at the second jackscrew 9 on the second bearing with spherical outside surface 10 inner ring between the second bearing with spherical outside surface 10 and grinding roller 8.The outer ring matrix of the first bearing with spherical outside surface 5 is connected by bolt 6 with first handle 2, the outer ring matrix of the second bearing with spherical outside surface 10 is connected by bolt 6 with second handle 11, first handle 2 and second handle 11 are the housing of inner hollow, and profile is cylindrical, it is inner that motor 3 and shaft coupling 4 are all positioned at first handle 2, and motor 3 is connected to one end of grinding roller 8 by shaft coupling 4.The power switch 1 of motor 3 is located at the outside of first handle 2.

When the sanding machine of the present embodiment assembles, first the two ends of grinding roller 8 are inserted into respectively in the inner ring of the first bearing with spherical outside surface 5 and the second bearing with spherical outside surface 10, the outer ring matrix of the first bearing with spherical outside surface 5 and the second bearing with spherical outside surface 10 is separately fixed on first handle 2 and second handle 11 by bolt 6, now first handle 2 and second handle 11 serve as casing simultaneously, in first handle 2, grinding roller end is connected with motor 3 by shaft coupling 4, then the first jackscrew 7 and the second jackscrew 9 on the first bearing with spherical outside surface 5 and the second bearing with spherical outside surface 10 inner ring is tightened, grinding roller 8 is positioned clamping, thus motor 3 can be controlled by the power switch 1 be arranged on first handle 2 and drive grinding roller 8 to rotate.

Operation principle: operating personnel are when buffing work-piece, first both hands are held on first handle 2 and second handle 11 respectively, by controlling the power switch 1 on first handle 2, sanding machine is operated, make surface of the work stress equalization like this, labor intensity of operating staff reduces greatly than one-handed performance simultaneously.Grinding roller 8 can according to different component surface processing requests simultaneously, after deenergization, by unscrewing the first jackscrew 7 and the second jackscrew 9 quick-replaceable grinding roller on the first bearing with spherical outside surface 5 and the second bearing with spherical outside surface 10 inner ring, thus adapt to multiple polishing occasion, reduce simultaneously and change the grinding roller time.

Above-mentioned is can understand and use invention for ease of those skilled in the art to the description of embodiment.Person skilled in the art obviously easily can make various amendment to these embodiments, and General Principle described herein is applied in other embodiments and need not through performing creative labour.Therefore, the invention is not restricted to above-described embodiment, those skilled in the art, according to announcement of the present invention, do not depart from improvement that scope makes and amendment all should within protection scope of the present invention.
