Abstract
The utility model discloses a hand-held bidirectional sawing machine belonging to a sawing mechanical field. The utility model comprises an input shaft; a driven spindle is arranged in parallel with the input shaft; a driven gear is arranged on the driven shaft; a spindle sleeve is sleeved on the driven shaft; a driven wheel is arranged on the spindle sleeve; the spindle sleeve and an exterior end of the driven shaft are provided with two sawblades which are close to each other respectively; one end of an output shaft is provided with a driving wheel; an intermediate shaft is arranged in parallel with the input shaft; one end of the intermediate shaft is provided with a change wheel; the other end of the intermediate shaft is provided with an idler wheel which is meshed with the driven gear outside ; among the driving wheel, the driven wheel and the change wheel is provided with a ring driving medium for three wheels to rotate synchronously. In a cutting operation, two sawblades rotate reversely to make counterforce offset thereby being easier for holding and more labor-saving for cutting for operators. Drive components of the whole machine in the utility model is reduced; the utility model is compact in structure, light in weight and more practical and the utility model can be applied to product processing of metal, wood and stone materials, field working and fire salvage.
Description
Technical field
The utility model relates to a kind of sawing machinery, the sawing machine of the positive and negative two-way simultaneous cutting of the two saw blades of particularly a kind of hand-held.
Background technology
Traditional cutting machine adopts the unidirectional rotation cutting of single saw blade mostly, and unidirectional cutting reaction force is big, is not suitable for hand-held working.Also has a kind of two-way sawing machine at present, comprise the power shaft that links to each other with original machine output shaft, power shaft is provided with first driving gear and second driving gear, be arranged with driven shaft in parallel with power shaft, driven shaft is provided with first driven gear, be provided with between first driving gear and first driven gear respectively and first driving gear and first driven gear tumbler gear of external toothing mutually, driven shaft is provided with axle sleeve, axle sleeve is provided with and second driving gear, second driven gear of external toothing mutually, and the speed ratio of first driving gear and first driven gear is identical with the speed ratio of second driving gear and second driven gear; The end of axle sleeve and driven shaft is respectively equipped with two saw blades pressed close to mutually.When power shaft rotated, first driving gear drove tumbler gear and rotates, and tumbler gear drives driven gear and rotates, and driven gear drives the saw blade that is arranged at its axle head and rotates, and the rotation direction of this saw blade is identical with turning to of power shaft; Meanwhile, second driving gear drives second driven gear and rotates, and then drives the saw blade rotation that is arranged on its axle head, the rotation direction of this saw blade and the switched in opposite of power shaft, the switched in opposite of two saw blades, when cutting operation, be cut material and can cancel out each other the reaction force of two saw blades, can make the operator be more prone to grip, cut more laborsaving, can avoid cutting machine to beat, make joint-cutting neatly accurate, the cutting accuracy height; But because of its complex structure, so the more weight of parts is too heavy, the operator is tired easily.
The utility model content
The purpose of this utility model is to provide a kind of hand held two-way sawing machine, to overcome unidirectional sawing and the overweight deficiency of part complete machine, reaches in light weight, compact conformation, and cutting is steady, more practical purpose.
For achieving the above object, a kind of hand held two-way sawing machine that the utility model provides, comprise power shaft, be arranged with driven shaft in parallel with power shaft, driven shaft is provided with driven gear, be set with axle sleeve on the driven shaft, axle sleeve is provided with driven pulley, the end of axle sleeve and driven shaft is respectively equipped with two saw blades pressed close to mutually, described output axle head is provided with a driving wheel, is arranged with jackshaft in parallel with power shaft, and jackshaft one end is provided with a reverse wheel, the jackshaft other end is provided with the idler gear with the driven gear external toothing, driving wheel, be provided with the annular driving member that this three-wheel is rotated synchronously between driven pulley and the reverse wheel.
Described annular driving member can be belt, chain or cog belt, corresponding driving wheel, driven pulley and reverse wheel be belt pulley, sprocket wheel or with the suitable profile of tooth belt wheel of cog belt.During work, power drives driving wheel, driving driven pulley and reverse wheel by power shaft and rotates synchronously, reverse wheel drives idler gear by jackshaft and rotates, further driving driven gear rotates, because reverse wheel effect, make the saw blade switched in opposite on driven shaft and the axle sleeve, when cutting operation, being cut material can cancel out each other to the reaction force of two saw blades, can make the operator be more prone to grip, cut more laborsavingly, can avoid cutting machine to beat, make joint-cutting neatly accurate, the cutting accuracy height; The utility model can cut materials such as timber, plastics and metal, and the drive disk assembly of complete machine reduces, compact conformation, in light weight, practical more.Can be applicable to product processing, field work or fire-disaster emergencies etc. such as metal, timber, stone material.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is this practical synchronous drive mechanism schematic diagram;
Among the figure, 1 saw blade, 2 axle sleeves, 3 driven pulleys, 4 reverse wheels, 5 annular driving members, 6 power shafts, 7 driving wheels, 8 hand-held internal combustion engines, 9 jackshafts, 10 idler gears, 11 driven gears, 12 driven shafts.
The specific embodiment
As figure, be the hand held two-way sawing machine, comprise power shaft 6, power shaft 6 is connected as a single entity with the output shaft of hand-held internal combustion engine 8, be arranged with driven shaft 12 in parallel with power shaft 6, driven shaft 12 is provided with driven gear 11, be set with axle sleeve 2 on the driven shaft 12, axle sleeve 2 is provided with driven pulley 3, the end of axle sleeve 2 and driven shaft 12 is respectively equipped with two saw blades 1 pressed close to mutually, described output shaft 6 ends are provided with a driving wheel 7, be arranged with jackshaft 9 in parallel with power shaft 6, jackshaft 9 one ends are provided with a reverse wheel 4, and jackshaft 9 other ends are provided with the idler gear 10 with driven gear 11 external toothings, driving wheel 7, be provided with the annular driving member 5 that this three-wheel is rotated synchronously between driven pulley 3 and the reverse wheel 4; Annular driving member 5 can be belt, chain or cog belt, corresponding driving wheel 7, driven pulley 3 and reverse wheel 4 be belt pulley, sprocket wheel or with the suitable profile of tooth belt wheel of cog belt.
During work, by power shaft 6 input power, driving wheel 7, driven pulley 3 and reverse wheel 4 rotate synchronously, jackshaft 9 drives idler gear 10 and rotates, further driving driven gear 11 rotates, because reverse wheel 4 effects, make saw blade 1 switched in opposite on driven shaft 12 and the axle sleeve 2, when cutting operation, be cut material and can cancel out each other the reaction force of two saw blades 1, can make the operator be more prone to grip, cut more laborsaving, can avoid cutting machine to beat, make joint-cutting neatly accurate, the cutting accuracy height; Hand-held internal combustion engine 8 of the present utility model can also substitute with electro-motor or air motor etc.
