Description
Technical field
The present invention relates to scissors manufacture field, relate in particular on the emery wheel in Shear sharpener and lift device.
Background technology
Scissors is hinged to install by two shear blades and forms, in the process of scissors, in order to make scissors in use more laborsaving, general is all to adopt the inner surface that two shear blades are in contact with one another to carry out respectively grinding, make the mid portion of the inner surface being in contact with one another be recess concave surface, to reduce the method that is in contact with one another area of two shear blades; On the very close shear blade of recess concave surface forming due to required grinding on shear blade with so that two hinge holes that shear blade is hinged, on the one hand, in order to ensure the grinding quality of shear blade surface concave surface, on the other hand, also affect installing and using of scissors in order not damage hinge hole, so when after shear blade depression in the surface shape concave surface completion of processing, must make shear blade surface leave emery wheel; Whether the method that tradition makes shear blade surface leave emery wheel is: first judge shear blade surface concave surface completion of processing by workman, when workman judges that shear blade surface concave surface is after completion of processing, workman grips rapidly shear blade makes shear blade leave emery wheel, but due to the restriction of workman's muscle power, workman can not accurately judge shear blade surface concave surface completion of processing at every turn in time on the one hand, the hand that workman grips shear blade on the other hand can produce shake unavoidably when shear blade is left to emery wheel, so not only be difficult to ensure grinding quality, also greatly reduced operating efficiency.
Summary of the invention
The object of this invention is to provide and a kind ofly can make emery wheel complete on the emery wheel in the Shear sharpener to automatically leaving shear blade surface after the grinding on shear blade surface to lift device.
For achieving the above object, the present invention has adopted following technical scheme: on the emery wheel in described Shear sharpener, lift device, comprise: mainframe and installing rack, be arranged on emery wheel and drive motors thereof on installing rack, wherein: on mainframe, be provided with base, on base, be provided with cylinder, the piston rod of described cylinder and one end of slide block fix, described slide block slides under the driving of cylinder on base, the other end of described slide block is connected with link, link is hinged by connecting axle and installing rack, described emery wheel and drive motors lay respectively at the both sides of connecting axle on installing rack, described drive motors drives emery wheel to rotate by transmission mechanism, on installing rack, be provided with wheel bracket, guide wheel is installed on wheel bracket, a side near drive motors on mainframe is provided with guide rail, the outer end of guide rail is provided with the inclined-plane downward-sloping by guide rail top surface, described guide wheel moves on guide rail, the weight of described drive motors ensures can make a side that is provided with drive motors on installing rack sink after guide wheel moves to inclined-plane, and installing rack is rotated around connecting axle, makes to be lifted away from and to cut across blade face on emery wheel.
Further, on emery wheel in aforesaid Shear sharpener, lift device, wherein: the structure of described transmission mechanism is: be positioned on the output shaft of drive motors of installing rack one side driving wheel is installed, be positioned on the opposite side of installing rack and be movably set with movable axis, on described movable axis, be installed with driven pulley, the other end of described movable axis is fixedly connected with emery wheel, on driving wheel and driven pulley, is provided with conveyer belt.
By the enforcement of technique scheme, the present invention has advantages of and can increase work efficiency, can make emery wheel automatically to leave shear blade surface after completing the grinding on shear blade surface.
