Description
Technical field
The present invention relates to the scissors manufacture field, relate in particular on the emery wheel in the 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 all is to adopt the inner surface that two shear blades are in contact with one another to carry out grinding respectively, makes the mid portion of the inner surface that is in contact with one another be the recess concave surface, to reduce the Method for Area that is in contact with one another of two shear blades; Because the recess concave surface that required grinding forms on the shear blade is very near using on the shear blade so that two hinge holes that shear blade is hinged; On the one hand; In order to guarantee the grinding quality of shear blade surface concave surface, on the other hand, also influence installing and using of scissors in order not damage hinge hole; So after shear blade depression in the surface shape concave surface completion of processing, must make the shear blade surface leave emery wheel; Whether the method that tradition makes the shear blade surface leave emery wheel is: judge shear blade surface concave surface completion of processing by the workman earlier; When the workman judges that shear blade surface concave surface is after the completion of processing; The workman grips shear blade rapidly makes shear blade leave emery wheel; But because the restriction of workman muscle power, the workman can not in time accurately judge shear blade surface concave surface completion of processing at every turn on the one hand, can produce shake unavoidably when workman's hand of gripping shear blade leaves emery wheel with shear blade on the other hand; So not only be difficult to guarantee grinding quality, also greatly reduced operating efficiency.
Summary of the invention
The purpose of this invention is to provide a kind of emery wheel that can make accomplishes lifting device on the emery wheel in the Shear sharpener that leaves the shear blade surface after the surperficial grinding of shear blade automatically.
For realizing above-mentioned purpose, the present invention has adopted following technical scheme: lift device on the emery wheel in the described Shear sharpener, comprising: mainframe and installing rack; Be arranged on emery wheel and drive motors thereof on the installing rack, wherein: mainframe is provided with base, and base is provided with cylinder; One end of the piston rod of said cylinder and slide block fixes; Said slide block slides on base under the driving of cylinder, and the other end of said slide block is connected with link, and link is hinged through connecting axle and installing rack; Said emery wheel and drive motors lay respectively at the both sides of connecting axle on installing rack, said drive motors drives emery wheel through transmission mechanism and rotates; Installing rack is provided with wheel bracket; Guide wheel is installed on wheel bracket, and the side near drive motors on mainframe is provided with guide rail, and the outer end of guide rail is provided with by guide rail top surface inclined downward; Said guide wheel moves on guide rail; The weight of said drive motors guarantees that guide wheel moves to a side that can make installing rack be provided with drive motors behind the inclined-plane and sinks, and installing rack is rotated around connecting axle, makes to be lifted away from the emery wheel and cuts across blade face.
Further; Lift device on the emery wheel in the aforesaid Shear sharpener; 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, be installed with driven pulley on the said movable axis; The other end of said movable axis is fixedly connected with emery wheel, and driving wheel and driven pulley are provided with conveyer belt.
Through the enforcement of technique scheme, the present invention has and can increase work efficiency, can make emery wheel after the grinding of accomplishing the shear blade surface, to leave the advantage on shear blade surface automatically.
Description of drawings
Fig. 1 is for lifting the structural representation of device on the emery wheel in the Shear sharpener of the present invention.
Fig. 2 is the decomposition assembling figure of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.
Like Fig. 1, shown in Figure 2, lift device on the emery wheel in the described Shear sharpener, comprising: mainframe 1 and installing rack 2; Be arranged on emery wheel 4 and drive motors 3 thereof on the installing rack, mainframe 1 is provided with base 16, and base 16 is provided with cylinder 5; One end of the piston rod of said cylinder 5 and slide block 17 fixes; Said slide block 17 is sliding on base 16 under the driving of cylinder 5, and the other end of said slide block 17 is connected with link 6, and link 6 is hinged through connecting axle 7 and installing rack 2; Said emery wheel 4 and drive motors 3 lay respectively at the both sides of connecting axle 7 on installing rack 2, said drive motors 3 drives emery wheel 4 through transmission mechanism and rotates; In the present embodiment; The structure of described transmission mechanism is: on the output shaft of the drive motors 3 of installing rack 2 one sides, driving wheel 12 is installed; Opposite side at installing rack 2 is movably set with movable axis 13; On movable axis 13, be installed with driven pulley 14, be installed with emery wheel 4 at the other end of movable axis 13, driving wheel 12 is provided with conveyer belt 15 with driven pulley 14; Installing rack 2 is provided with wheel bracket 8; Guide wheel 9 is installed on wheel bracket 8, and the side near drive motors 3 on mainframe 1 is provided with guide rail 10, and the outer end of guide rail 10 is provided with by guide rail 10 top surface inclined downward 11; Said guide wheel 9 moves on guide rail 10; The weight of said drive motors 3 guarantees that guide wheel 9 moves to a side that can make installing rack 2 be provided with drive motors behind the inclined-plane and sinks, and installing rack 2 is rotated around connecting axle 7, makes to be lifted away from the emery wheel 4 and cuts across blade face.In practical application, mainframe 1 is provided with the scissors anchor clamps that can place shear blade, during the processing shear blade; Shear blade is installed in the scissors anchor clamps, and cylinder 5 promotes slide block 17 and on base 16, moves around, and drives emery wheel 4 synchronously and moves on the shear blade surface; Grinding is carried out on the shear blade surface, and when emery wheel 4 was accomplished the grinding to shear blade depression in the surface shape concave surface, the guide wheel 9 of installing rack 2 bottoms just in time moved on the inclined-plane 11; At this moment, under the weight of drive motors 3, an end 11 sinkings along the inclined-plane of drive motors 3 are installed on the installing rack 2; Driving installing rack 2 rotates around connecting axle 7; The end that emery wheel 4 is installed on the installing rack 2 is risen, thereby makes emery wheel 4 leave the shear blade surface, through promptly accomplished behind the aforesaid operations emery wheel 4 automatically on lift work.The present invention has and can increase work efficiency, and can make emery wheel after the grinding of accomplishing the shear blade surface, leave the advantage on shear blade surface automatically.
