Description
Technical field
The present invention relates to the cutter sweep of materials such as a kind of timber, plastics or metal, particularly relate to a kind of hand-held saw blade cutting machine.
Background technology
In the prior art, a kind of hand-held saw blade cutting machine is arranged, comprise housing, be provided with a power transmission shaft in the housing, power transmission shaft one end connects power input device, the power transmission shaft other end is provided with a saw blade, and power input device passes to saw blade by power transmission shaft with turning moment, and saw blade cuts off material in high speed rotating; Its weak point is: as cutting edge, its cutting speed is slow with metal saw blade or resin wheel sheet for cutting machine of the prior art, and the cutting spark is big; When carrying out cutting operation, be cut material and can produce reaction force, make the hand-held effort saw blade.
Summary of the invention
The purpose of this invention is to provide a kind of cutter with double saw bits, make cutting more laborsaving, cutting speed is fast, and joint-cutting is neatly accurate.
The object of the present invention is achieved like this: a kind of cutter with double saw bits, comprise housing, be provided with a power transmission shaft in the housing, described power transmission shaft is provided with first driving gear and second driving gear, also be provided with the driven shaft that be arranged in parallel with power transmission shaft in the housing, 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 idler gear of external toothing mutually, driven shaft is provided with axle sleeve, described 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; Be provided with bearing between axle sleeve and the driven shaft, an axle head of driven shaft and axle sleeve stretches out outside the housing, and the axle head of described driven shaft is provided with first saw blade, and the axle head of described axle sleeve is provided with second saw blade, and first saw blade and second saw blade are pressed close to mutually.
When power transmission shaft rotated, first driving gear drove idler gear and rotates, and the intermediate gear drives driven gear rotates, and driven gear drives first saw blade that is arranged at its axle head and rotates, and the rotation direction of first saw blade is identical with turning to of power transmission shaft; Meanwhile, second driving gear drives second driven gear and rotates, and then drive is arranged on second saw blade rotation of its axle head, the rotation direction of second saw blade and the switched in opposite of power transmission shaft, speed ratio because of first driving gear and first driven gear is identical with the speed ratio of second driving gear and second driven gear again, therefore, the switched in opposite and the speed of first saw blade and second saw blade are identical, when cutting operation, be cut material and can cancel out each other the reaction force of first saw blade and second saw blade, 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; First saw blade and second saw blade can adopt the alloy saw blade, and its cutting spark is little, and cutting speed is fast; In case of necessity, also can unload next saw blade, can be used as common cutting machine and use, when carrying out the stone material cutting, also can use skive; The present invention can cut materials such as timber, plastics and metal, can make cutting laborsaving, and cutting speed is fast, and joint-cutting is neatly accurate, can be applicable to product processing, field work or fire-disaster emergencies etc. such as metal, timber, stone material.
Described first saw blade or second saw blade comprise saw blade pedestal and blade bodies, and blade bodies is fixed on the end face of saw blade pedestal.The mode that blade bodies can adopt welding, rivets or be threaded fixedly the time with the saw blade pedestal is connected.
The axle head of described driving shaft is connected with gasoline prime mover.Gasoline prime mover has little, the lightweight advantage of volume, can alleviate weight of the present invention, makes hand-held laborsavingly, is not subjected to power limitations, is particularly suitable for field work; Certainly, the axle head of this driving shaft also can connect motor or air motor etc.
