Description
【発明の詳細な説明】 〔技術分野〕 この発明はジグソーに関するものである。[Detailed description of the invention] 〔Technical field〕 This invention relates to a jigsaw.
従来のジグソーは、第１図および第２図に示すように、
鋸刃３０がプランジャ３１に固足されると、この鋸刃３
０は同一範囲内で往り動を繰り返すのみであり、被切削
材３２に圧接して切削作業を行なう部分は、被切削材３
２の厚さと往復動の振幅を７ＪＯえたＡ部のみである。The conventional jigsaw, as shown in Figs. 1 and 2,
When the saw blade 30 is firmly attached to the plunger 31, this saw blade 3
0 only repeats back and forth movement within the same range, and the part that presses against the workpiece 32 and performs cutting work is the workpiece 3
It is only part A, which has the thickness and amplitude of reciprocating motion 7JO greater than that of Part 2.
したがって、同一厚さの被切削材３２を連続して切削す
ると、被切削材３２に圧接される部分のみ偏摩耗する。Therefore, if the workpiece 32 of the same thickness is continuously cut, only the portion that is pressed against the workpiece 32 will wear unevenly.
そのため、他の部分は摩耗していないにもかかわらす使
えなくなり、鋸刃３０の寿命が短かかった。As a result, the other parts became unusable even though they were not worn, and the life of the saw blade 30 was shortened.
この発明は、鋸刃の偏摩耗を防止し、鋸刃の切味を長持
ちきせることかできるジグソーを提供することを目的と
する。SUMMARY OF THE INVENTION An object of the present invention is to provide a jigsaw that can prevent uneven wear of the saw blade and maintain the sharpness of the saw blade for a long time.
この発明のジグソーは、鋸刃を取付ける鋸刃ホルダをジ

はピン１７を固定支軸１３に対して偏心して設ける。A gear 11 press-fitted onto the output shaft 10' of the motor 10 meshes with a gear 12. The gear 12 is supported by a fixed support shaft 13, and the gear 12 is provided with an eccentric cam 14 eccentric from the center of rotation. The eccentric cam 14 has a horizontal elongated hole ts.
A balance weight 15 having a diameter is engaged and arranged. The balance weight 15 is provided with a long hole 15b that engages with a guide pin 16B protrudingly fixed to the cover 2 so as not to rotate with respect to the rotation of the gear 120 but only to reciprocate. A weight holder 1 is attached to the gear 12 in contact with the side surface of the eccentric cam 14.
8 with screws 19, and balance weight 15 with gear 1.
It should be kept between 2 and 2. A pin 17 is provided on the weight holder 18 eccentrically with respect to the fixed support shaft 13.

で固定されている。The eccentric direction of the pin 17 is opposite to the eccentric direction of the eccentric cam 14. A roller 20 is rotatably fitted onto the pin 17, and the connector 21 is arranged such that the roller 20 engages with the inner wall of the groove-shaped connector 21 in a movable manner. Connector 2
1 is fixed to the plunger 22 with a connector holder 23 and screws 24.

るため、ピン１７の回転運動はコネクタ）１の往復運動
すなわち、プランジャ２２の往復運動に変換される。The rotation of the operating motor output shaft 10' is transmitted from the gear 11 to the gear 12, and further to the weight holder 18 connected to the gear 12.
Rotate. Similarly, the pin 17 fixedly protruding from the weight holder 18 rotates while maintaining its entire eccentric position. pin 17
is engaged with the connector 21 via the roller 20,
Since the roller 20 on the pin 17 rolls on the inner wall of the connector 21, the rotational movement of the pin 17 is converted into a reciprocating movement of the connector) 1, that is, a reciprocating movement of the plunger 22.

対方向に動く。On the other hand, the eccentric shaft 14, which is eccentric from the central axis of the gear 12 to a position facing the pin 17 of the weight holder 18, also rotates similarly to the gear 12. The balance weight 15 engaged with the outer periphery of the eccentric shaft 14 is connected to the elongated hole 15m of the engagement part and the guide pin 1.
63, it can only move in the vertical direction without rotating. The balance weight 15 moves in the opposite direction because it moves in opposition to the plunger 22.
すなわちプランジャ２２の上死点に対し、バランスウェ
イト１５の下死点の位置になるように動く。In other words, the balance weight 15 moves to the bottom dead center position relative to the top dead center of the plunger 22.
そのため、バランスウェイト１５は本体のアンバランス
を消勢するように動き、本体のバランスを取る。Therefore, the balance weight 15 moves to eliminate the imbalance of the main body, thereby balancing the main body.

鋸刃２８を本体側へ収容した状態を示す。Next, the movement of the saw blade 28 will be explained. Since the saw blade 28 is fixed to the plunger 22, it reciprocates with an amplitude twice the eccentricity of the pin 17. Here, when the drive unit cover 29F is removed from the cover 3 and the screw 24 is loosened to weaken the clamping force between the connector 21 and the connector holder 23, the plunger 22 can be slid relative to the connector 21.
The reciprocating position of the blade 28 can be moved. FIG. 4 shows the saw blade 28 housed in the main body.
このように、コネクタ２１とプランジャ２２の相対位置
を、ビス２４を調整することにより移動することができ
、この操作により、被切削材と鋸刃２８の圧接する部分
Ｐ替えることが可能となる。In this way, the relative position of the connector 21 and the plunger 22 can be moved by adjusting the screw 24, and by this operation, it is possible to change the portion P where the material to be cut and the saw blade 28 come into pressure contact.
そのため、鋸刃２８の偏摩耗を防止し、初期の切味を長

き、鋸刃２８に無理な力が作用せず、鋸刃２８が変形す
ることも少なく安定した切削を行なうことができる。Therefore, uneven wear of the saw blade 28 can be prevented, the initial sharpness can be maintained for a long time, and the life of the saw blade 28 can be extended. In addition, the amount by which the saw blade 28 protrudes from the base 7 can be changed depending on the thickness of the material to be cut (5), so that no excessive force is applied to the saw blade 28, and the saw blade 28 is less likely to deform. Stable cutting can be performed.
この発明は、鋸刃の偏摩耗を防止して鋸刃の切味を長持
ちさせることができ、また被切断材の厚みに応じて鋸刃
の突出量を変えて安定した切断および鋸刃の変形防止を
図ることができるという効果がある。This invention prevents uneven wear of the saw blade and prolongs the sharpness of the saw blade, and also changes the protrusion amount of the saw blade according to the thickness of the material to be cut to ensure stable cutting and deformation of the saw blade. This has the effect of being able to prevent this.
