Abstract
The utility model discloses a circular saw, which belongs to the woodworking machinery, and consists of a base, a frame, an electric motor, a control circuit, an eccenter, upper and lower rockers, a tension screw, a thread saw blade tension mechanism, a saw blade claw, a pressure foot, a worktable and a thread saw blade. Upper side of the right of the frame is provided with a saw dust blowing device consisting of an air cell, a hose and a blowing nozzle. The thread saw blade tension mechanism consists of a tension spring, a sleeve, a small shaft and a cam button. A direct current electric motor realizes stepless timing through a bidirectional controlled silicon timing circuit. The utility model has convenient operation and flexible use, moreover, the thread saw blade can tighten quickly and the saw dust can be cleared immediately, thus the utility model can be used extensively for cutting of complex patterns of wooden and plastic handicraft articles.
Description
The utility model relates to woodworking machinery, a kind of scroll saw machine that is used for the complex figure cutting of Wood craft and plastic crafts of more clearly saying so.
The scroll saw machine is mainly used in the cutting of curve and straight line, can finish the cutting of various complex figures.People mainly process wooden, plastic crafts by hand saws before the invention of scroll saw machine, owing to adopt manual operations, at the bottom of the efficient, labour intensity is big.After the invention of scroll saw machine, saw blade is by motor-driven, and the saw blade cutting efficiency improves greatly.Simultaneously because work can be in the workbench upper support, can be according to various complex figures, mobile working arbitrarily cuts, and labour intensity also reduces greatly.Machining accuracy also improves thereupon.But the step speed change that present scroll saw machine is single speed or two, three speed can not realize infinitely variable speeds, is not suitable for the occasion of speed change on a large scale, and the scope of application is extensive inadequately.In addition, the tension mechanism of thread saw blade is comparatively complicated, and operation is convenient inadequately.Wood chip easily is deposited near the saw kerf, again because of not having special-purpose illuminating lamp, observation when influencing work and machining accuracy.
The purpose of this utility model is to overcome above-mentioned shortcoming and defect, and a kind of continuously variable is provided, and is applied widely, and the tension mechanism of thread saw blade is simple, easy to operate, and wood chip can in time be cleared up, and dedicated illumination is arranged again, is convenient to the scroll saw machine of observing and processing.
In order to achieve the above object, the utility model is by base, be fixed on the support on the base, be fixed on motor and control circuit thereof on the base, be installed in the eccentric wheel on the motor shaft, with little gusset piece that is installed on the eccentric wheel, be hinged on the gusset piece and the following rocking bar on support of being coupling, be installed in down the pulling force screw rod of rocking bar left part, left end be installed in pulling force screw rod top and be coupling on support on rocking bar, be installed in the thread saw blade tension mechanism of pulling force screw rod upper end, be installed in two saw blade pawls of rocking bar right-hand member up and down, the presser feet of rack-mount end, be installed in the workbench on the base and pass the thread saw blade that workbench is installed in up and down on two saw blade pawls and constitute.The support right-hand member is being fixed the air bag that an opening between it and last rocking bar makes progress, and is connecting a flexible pipe on the opening of air bag, and the other end of flexible pipe is connecting a blow gun that is fixed in the presser feet vertical rod.Blow gun can in time blow away wood chip towards the saw kerf of work piece, is convenient to observe and improve machining accuracy.The wood chip that falls workbench is then taken away by the dust collecting opening that is positioned at the bottom.
The thread saw blade tension mechanism is constituted by the stage clip that is sleeved on pulling force screw rod top, lining and with the cam button that little axle is connected pulling force screw rod upper end.In the time of need be with the thread saw blade tensioner, as long as the end of flicking cam button forces cam and lining contact point to rise along cam curve, cam be just depressed lining along the elastic force that the pulling force screw rod overcomes stage clip.This moment, up and down rocking bar left end spacing reduced, and they are fulcrum with the axle that is coupling with support respectively, and right-hand member upwards opens downwards respectively, with the thread saw blade tensioner.
Motor is a direct current generator, and control circuit is the controllable silicon stepless speed regulation circuit, so just can realize stepless speed regulation, has enlarged its scope of application.Illuminating lamp also is installed on the support, is convenient to observe and processing.The support upper right side can also be installed transparent goggle, prevents that the wood chip that disperses from interrupting the view, and is convenient to observe.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of infinitely variable speeds, applied widely, the tensioner of thread saw blade and lax simple and direct, and wood chip can in time be cleared up, and transparent goggle and dedicated illumination are arranged again, is convenient to observation and processing, thereby can improve the scroll saw machine of machining accuracy.It can be widely used in the cutting processing of Wood craft and plastic crafts complex figure, curve and straight line.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.
Fig. 1 is the structural representation of embodiment 1.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the electrical schematic diagram of the bidirectional triode thyristor stepless speed regulation circuit of embodiment 1.
Fig. 4 is the structural representation of embodiment 2.
Illustrated in figures 1 and 2, embodiment 1 by base 16, support 6, motor 1 and control circuit 13 thereof, eccentric wheel 2, gusset piece 3, down rocking bar 5, pulling force screw rod 17, go up rocking bar 4, up and down rocking bar 4 and 5 be connected with support spools 23, saw blade pawl 8, presser feet 24, workbench 10, thread saw blade 7 and thread saw blade tension mechanism form.The air bag 11 that opening makes progress is installed between support 6 upper right sides and the last rocking bar 4, and it and flexible pipe 22, blow gun 12 are formed bits blower.The thread saw blade tension mechanism is made up of stage clip 21, lining 20, little axle 19 and cam button 9.Illuminating lamp 18 is installed on the support 6, is convenient to observe.Dust collecting opening 14 can external dust catcher, siphons away wood chip.
Scroll saw machine theory of mechanics adopts double rocker mechanism up and down.Motor 1 drives eccentric wheel 2, and the eccentric wheel rotation drives upper and lower rocking bar 4,5 by gusset piece 3, diaxon 23 swings on support 6, thus realize two rocking bar reciprocally swingings.Thread saw blade 7 hangs on the saw blade pawl 8, moves with the rocking bar reciprocally swinging is upper and lower up and down, thus cut workpiece.Along with swinging up and down of last rocking bar 4, air bag 11 is compressed repeatedly, is loosened, and gas blows out from blow gun 12, the cleaning wood chip.
Shown in Figure 3, direct current generator 1 is by the speed governing of bidirectional triode thyristor stepless speed regulation circuit.It is made up of rectifying block 25, bidirectional triode thyristor 26, potentiometer 27 and resistor-capacitor unit.
