As further technical scheme, described draw-in groove is square draw-in groove or trapezoidal draw-in groove.
As further technical scheme, the middle part that described directive wheel comprises guide wheel main body described in guide wheel main body, axis, bearing is provided with the central through hole with described bearing fit, be connected by bearing between described axis with described guide wheel main body, one end of described central through hole is provided with cover plate, its by bolt and described guide wheel main body affixed.
As further technical scheme, between described guide wheel main body and described cover plate, be provided with packing ring.
As further technical scheme, the side away from described cover plate in described guide wheel main body is provided with annular boss, described annular boss and described guide wheel main body one and coaxial, and its internal diameter is less than the internal diameter of described central through hole.
As further technical scheme, the radial direction along described guide wheel main body is evenly provided with four through holes.
As further technical scheme, described elastic overcoat is silicone jacket.
As further technical scheme, the outer rim of described elastic overcoat is provided with a scroll saw gathering sill.
The beneficial effect adopting technique scheme to produce is:
Adopt elastic overcoat and the directive wheel that is mated, when changing overcoat, without the need to dismantling directive wheel, can directly dismounting, time saving and energy saving, the frame for movement of directive wheel can not be affected, the service life of prolongation guider.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional structure schematic diagram in Fig. 1.
In figure: 1, directive wheel; 11, guide wheel main body; 12, axis; 13, bearing; 14, central through hole; 15, cover plate; 16, packing ring; 17, annular boss; 18, through hole; 2, elastic overcoat; 3, draw-in groove, 4, scroll saw gathering sill.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
1-2 as shown in the figure, is an embodiment of a kind of silicon rod slicing lathe guider (NTC442 slicer) of the utility model, comprises:
Directive wheel 1, elastic overcoat 2.Directive wheel 1 outer rim is provided with the draw-in groove 3 mated with elastic overcoat 2, and it is square draw-in groove.Elastic overcoat 2 is the silicone jacket of single groove, is set in draw-in groove 3, and square draw-in groove 3 can make the easy accessibility of overcoat, good positioning effect, connect more firm.Elastic overcoat 2 is silicone jacket, and its outer rim is provided with a scroll saw gathering sill 4, plays guide effect.Draw-in groove 3 also can be trapezoidal draw-in groove, not shown in the drawings, and trapezoidal draw-in groove being set with the cross section coordinated with the cross section of trapezoidal draw-in groove is also trapezoidal elastic overcoat 2, also can reach firmly locating effect.Adopt elastomeric material make overcoat, utilize in unloading process the elastic force of overcoat self can when directive wheel 1 need not be dismantled direct dismounting overcoat, convenient and swift, do not affect the frame for movement of directive wheel 1.
Directive wheel 1 comprises guide wheel main body 11, axis 12, bearing 13.The middle part of guide wheel main body 11 is provided with the central through hole 14 coordinated with bearing 13, is connected between axis 12 with guide wheel main body 11 by bearing 13, makes directive wheel 1 sound construction and compact, and it is little to rotate the resistance born.
One end of central through hole 14 is provided with cover plate 15, its by bolt and guide wheel main body 11 affixed, the bearing jointing structure of inside is played a protective role, is not easy to collide with or polluted.
Be provided with packing ring 16 between guide wheel main body 11 and cover plate 15, packing ring 16 is provided with the screw corresponding with the screw on cover plate 15, and both are fixedly connected with guide wheel main body 11 by bolt-through cover plate 15 and packing ring 16.Prevent from occurring between axis 12 and cover plate 15 to rub or collide with in motion process, affect result of use and service life.
Guide wheel main body 11 is provided with annular boss 17 away from the side of described cover plate 15, annular boss 17 and guide wheel main body 11 one and coaxial, its internal diameter is less than the internal diameter of central through hole 14.Annular boss 17 can protect axis 12, makes it not easily fracture because of beat in motion process, also can play a protective role to bearing jointing structure.
Radial direction along guide wheel main body 11 is evenly provided with four through holes 18.Through hole 18 is the through hole of arc-shaped, can handled easily personnel hold guide wheel main body 11 and apply active force in disassembly process, the deadweight of guide wheel main body 11 can also be alleviated to a certain extent, under guarantee serviceability and the prerequisite in life-span, make it more stable in motion process.
During use, scroll saw as cutter sweep is limited in the scroll saw gathering sill 4 of elastic overcoat 2, and guider, centered by axis 12, rotates along with the movement of the scroll saw be wound on elastic overcoat 2, make scroll saw remain winding state, and then complete cutting operation smoothly.
Adopt elastic overcoat and the directive wheel that is mated, when changing overcoat, without the need to dismantling directive wheel, can directly dismounting, time saving and energy saving, the frame for movement of directive wheel can not be affected.Directive wheel itself is stable, from heavy and light, and longer service life.
