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 utility model 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 for ease of those skilled in the art and use utility model 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 utility model is not limited to above-described embodiment, and those skilled in the art, according to announcement of the present utility model, do not depart from improvement that the utility model category makes and amendment all should within protection domain of the present utility model.
