Abstract
The invention relates to a small-strike reciprocated safe disc electric saw, which comprises base, motor, saw blade, and saw axle, wherein the motor is mounted on the base; the saw blade sheathes the axle; the axle via axle bearing is mounted in the bearing base; the saw blade axle is eccentrically fixed with pushing pin; the rotation axle of motor is fixed with eccentric wheel; the eccentric wheel and pushing pin are transmitted via connecting rod; the eccentric wheel and connecting rod have eccentric wheel bearing between them; the pushing pin and connecting rod have pushing pin bearing between. When working, the saw blade rotates the saw blade axle to vibrate without hurting people; and since the work piece has no flexibility, it can cut the piece successfully.
Description
Technical field
The present invention relates to cutting mechanics, particularly to the improvement of disk electric saw.
Background technology
The disk electric saw is made up of motor, saw blade, and saw blade is installed in the rotating shaft of motor, by the direct driven rotary of motor, or be installed on the saw blade axis that has belt pulley, be arranged with corresponding belt pulley on the machine shaft, motor drives the saw blade rotation by belt transmission, in order to cut workpiece.Because the saw blade high speed rotating, sawtooth is sharp, very easily causes personal injury during misoperation.
Summary of the invention
The object of the invention is to provide a kind of tissue, disk electric saw safe in utilization of can not damaging, and uses with convenient.
The solution of the present invention is: short-stroke reciprocating type safety electric disc saw, comprise support, motor, saw blade, saw blade axis, motor is installed on the support, saw blade is set on the saw blade axis, and saw blade axis is installed in the saw blade axle bed on the support by the saw blade axis bearing, and eccentric position is fixed with the push-and-pull pin on the saw blade axis, be fixed with eccentric wheel on the machine shaft, be connected transmission by connecting rod between eccentric wheel and push-and-pull pin, be provided with eccentric shaft bearing between eccentric wheel and connecting rod, be provided with the push-and-pull pin bearing between push-and-pull pin and connecting rod.
Distance≤1.5mm between two adjacent sawtooth on the saw blade, eccentric eccentric distance is 1 * L/r mm, and wherein r is the saw blade radius, and L is the distance between push-and-pull pin and saw blade axis.
Advantage of the present invention is: make reciprocally swinging owing to adopted eccentric wheel to drive saw blade axis by connecting rod, saw blade is done the swing vibration around saw blade axis when work, because of the jaggy pitch that adopts little, it is common serration saw blade, the amplitude of its vibration can not injure human body in the elastic range of human skin tissue, and during cut workpiece, because workpiece does not have elasticity, thereby the motion of sawtooth can be cut it.The present invention cuts reliably, has guaranteed user's safety simultaneously again.
Description of drawings
The invention will be further described with embodiment with reference to the accompanying drawings below.
Accompanying drawing is a structural representation of the present invention.
Mark among the figure: 1 motor, 2 supports, 3 saw blade axle beds, 4 saw blade axis bearings, 5 saw blade axis, 6 saw blades, 7 push-and-pull pins, 8 push-and-pull pin bearings, 9 connecting rods, 10 eccentric shaft bearings, 11 eccentric wheels, 12 machine shafts.
The specific embodiment
Referring to accompanying drawing, the short-stroke reciprocating type safety electric disc saw of embodiment, comprise support 2, motor 1, saw blade 6, saw blade axis 5, motor 1 is installed on the support 2, saw blade 6 is set on the saw blade axis 5, saw blade axis 5 is installed in the saw blade axle bed 3 on the support 2 by saw blade axis bearing 4, can freely swing, eccentric position is fixed with push-and-pull pin 7 on the saw blade axis 5, be fixed with eccentric wheel 11 on the machine shaft 12,7 of eccentric wheel 11 and push-and-pull pins are connected transmission by connecting rod 9, and 9 on eccentric wheel 11 and connecting rod are provided with eccentric shaft bearing 10,9 on push-and-pull pin 7 and connecting rod are provided with push-and-pull pin bearing 8, to reduce friction.
During motor 1 work, machine shaft 12 drives eccentric wheel 11 and rotates, because the effect of eccentric shaft bearing 10 and connecting rod 9, this rotational action is converted into moving back and forth of connecting rod 9.Because saw blade axis 5 can freely swing, push-and-pull pin 7 fixedly is located at the eccentric position of saw blade axis 5, thereby the moving back and forth of connecting rod 9, constantly push away, draw push-and-pull pin 7, saw blade axis 5 is swung back and forth, drive saw blade 6 and swing back and forth, sawtooth swings back and forth, and reaches the purpose of cut workpiece.
Distance≤1.5mm between two adjacent sawtooth on the saw blade, promptly popular " the serration saw blade " said, eccentric eccentric distance is 1 * L/r mm, and wherein r is the saw blade radius, and L is the distance of 5 of push-and-pull pin 7 and saw blade axis.Like this, the amplitude of fluctuation≤3mm of sawtooth during work, because the elasticity of human body skin, such moving can not damage human body, guaranteed the safety of using.
