Description
[technical field]
The utility model relates to a kind of scroll saw machine, particularly relates to a kind of scroll saw machine of fast changeable saw blade.
[background technology]
As Fig. 1, general scroll saw machine 1 consists predominantly of a upper arm 11 of the upper and lower intersegmental distance of being separated by and a underarm 12, and screws togather hook joint sheet 16 on bar 13, a nut 14, the elastic parts 15,, once a hook joint sheet 17 and a saw blade 18.This screws togather bar 13 is to run through upper arm 11 1 ends 111, and has a thread segment 131 that upwards passes upper arm 11 and screw togather with nut 14, and one pass downwards upper arm 11 and with fixed affixed section 132 of last hook joint sheet 16.This elastic parts 15 is set in and screws togather 13 affixed sections 132 peripheries of bar, and is resisted against 11 on hook joint sheet 16 and upper arm.This time hook joint sheet 17 is to be fixed on the underarm 12.This saw blade 18 has the end 181 with last hook joint sheet 16 hook joints, reaches the other end 182 with following hook joint sheet 17 hook joints.
Whereby,, and make and screw togather bar 13 and when moving and screwing togather, just can upwards drive hook joint sheet 16 with nut 14 to enterprising when turn nut 14, and tension saw blade 18 1 ends 181, make saw blade 18 obtain the location.When reverse turn nut 14, and make elastic parts 15 ejections screw togather bar 13 when breaking away from nut 14 downwards, just can drive hook joint sheet 16 to bottom offset, and unclasp saw blade 18, make saw blade 18 no longer be in tight state, can take off saw blade 18 by last hook joint sheet 16 and 17 of following hook joint sheets for the operator.Yet though said modules can reach the purpose of changing saw blade 18, so it still has following disappearance and has to be solved when practical operation:
Because last hook joint sheet 16 is by nut 14 and the action that screws togather that screws togather bar 13, reach, the purpose of following lifting displacement, therefore, make and screw togather on the bar 13, the distance of bottom offset reaches tension or unclasps the effect of saw blade 18, certainly will want forward or counter-rotating nut 14 several circles, just can make and screw togather bar 13 and have enough shift lengths, so, should continue the action of rotary nut 14, not only expend time in and the action on quite have some setbacks, and the drawing tension of saw blade 18 more can have the too tight fracture easily of drawing tension because of different replacing persons, or too pine can't be finished disappearances such as scroll saw operation smoothly.

[specific embodiment]
As Fig. 2, Fig. 3, a preferred embodiment of the scroll saw machine of the utility model fast changeable saw blade is to include a body 2, to support assembly 3, a saw blade 4, a push rod 5, a driven unit 6 and an elastic recovery assembly 7.
This body 2 has a upper arm 21 and a underarm 22 of upper and lower be separated by an intersegmental distance and hollow.
This supports assembly 3 has one and is hubbed on last traces 31, in the upper arm 21 and is hubbed on the following hook joint sheet 35 that hook joint sheet 34, on the moving seat 33, of following trace 32, pivots in the underarm 22 is fixed on down trace 32 1 ends 321, reaches a locating piece 36 that is fixed on trace 31 1 end faces 312.The moving seat 33 of this pivot has one with the point of elbow 331 of 311 pivots of last trace 31 1 ends, is oppositely extended and a upper end 332 and a bottom 333 that can forward and backward swing by point of elbow 331, and one is formed on upper end 332 and along the screw 334 of axis X extension.Should go up hook joint sheet 34 and be and link with the moving seat of pivot 33 bottoms 333 and mutual corresponding with following hook joint sheet 35.This locating piece 36 has a perforation 361 that runs through along this axis X.
This saw blade 4 is to stand 22 of upper arm 21 and underarms, and has the end 41 with last hook joint sheet 34 hook joints, and with the other end 42 of following hook joint sheet 35 hook joints.
This push rod 5 is to pass the perforation 361 of locating piece 36 along last trace 31 end faces 312, and has an end 51 that screws togather with the moving seat of pivot 33 screws 334, and is in reverse to the other end 52 of an end 51.
This driven unit 6 has a slide block 61 and an eccentric block 62 and a driving lever 63.This slide block 61 is and last trace 31 coaxial being hubbed in the upper arm 21, and has a upper end 611 that contacts with push rod 5 other ends 52, and a lower end 612 that contacts with eccentric block 62.This eccentric block 62 has nearer short brink 622 of a perforation 621 that is positioned at eccentric position, a distance perforation 621 and a distance perforation 621 long sides 623 far away.But this driving lever 63 is turn ground runs through upper arm 21, and has a section of fastening 631 that fastens in eccentric block 62 perforation 621, and a holding section 632 that passes upper arm 21, makes driving lever 63 and eccentric block 62 formation interlocks.
This elastic recovery assembly 7 has one first elastic parts 71 and one second elastic parts 72.This first elastic parts is to be set on the push rod 5, and is resisted against 36 of push rod 5 other ends 52 and locating pieces, makes push rod 5 can return back to original position after external force discharges.This second elastic parts 72 is to be set on the push rod 5, and is resisted against 611 of locating piece 36 and slide block 61 upper ends, makes slide block 61 return back to original position after external force discharges.This first, second elastic parts the 71, the 72nd, a kind of spring of the different hands of spiral, and this second elastic parts 72 is that ring is put in first elastic parts, 71 peripheries.
Consult Fig. 4, Fig. 5, in the time will unclasping saw blade 4, only need holding section 632 about 180 degree of turn driving lever 63, just can drive eccentric block 62 rotates, make eccentric block 62 in the turn process, contact with slide block 61 from short brink 622, converting long side 623 gradually to contacts with slide block 61, make eccentric block 62 utilize long side 623 and short brink 622 formed gaps, ejection slide block 61 lower ends 612 backward, and urge slide block 61 lower ends 612, make elastic force that slide block 61 upper ends 611 overcome second elastic parts 72 ejection push rod 5 other ends 52 forward, and obtain the location because lower end 612 is stopped by eccentric block 62 long sides 623.At this moment, this push rod 5 can overcome the elastic force of first elastic parts 71, and the moving seat of ejection pivot 33 upper ends 332 forward synchronously, and making the moving seat of pivot 33 is centre of gyration turn with point of elbow 331, and drive bottom 333 and drive and go up hook joint sheet 34 and displacement backward downwards, make hook joint sheet 34 unclasp saw blade 4 one ends 41.Whereby, the operator just can take off saw blade 4, and the new saw blade 4 that changes the outfit.
Consult Fig. 3, Fig. 4, when wanting tension saw blade 4, same holding section 632 about 180 degree that only need turn driving lever 63, just can drive eccentric block 62 rotates, eccentric block 62 is contacted with slide block 61 with short brink 622, and utilize long and short avris 623,622 formed gaps, unclasp slide block 61 lower ends 612, make slide block 61 and push rod 5 after external force discharges, by the back stretch of first, second elastic parts 71,72 displacement and involution original position backward.At this moment, this push rod 5 one ends 51 are the moving seat of tractive pivot 33 upper ends 331 backward, and making the moving seat of pivot 33 be centre of gyration turn with point of elbow 331, and drive bottom 333 and drive and go up hook joint sheet 34 and make progress and displacement forward, make hook joint sheet 34 tension saw blades 4 one ends 41.Whereby, this saw blade 4 is to be tight operational state.
Consult Fig. 6, this push rod 5 also can be by the screw togather degree of depth of an end 51 with the moving seat of pivot 33 screws 334, adjust the distance of push rod 5 other ends 52 and the moving seat 33 of pivot, and then change the bullet tension force of first elastic parts 71, further change push rod 5 traction driven-movable blocks 33 and reach the drawing tension of going up hook joint sheet 34, and can reach the purpose of adjusting saw blade 4 tension force.
