本願発明に係るクランプ装置１は、機械加工工程等において物品を固定（クランプ）するためのものである。以下で説明するクランプ装置は、特に縦押し型とし、物品を上方から押圧してクランプするものである。クランプ装置１を構成する各部品は、通常は金属製であるが、所定の強度を有していれば、金属製に限定されるものではなく、樹脂製であってもよく、金属製に限定されるものではない。尚、これは本願発明のクランプ装置の一例を示すものであり、その他の変形例も可能である。 The clamp device 1 according to the present invention is for fixing (clamping) an article in a machining process or the like. The clamping device described below is particularly a vertical push type, and clamps an article by pressing it from above. Each component constituting the clamp device 1 is usually made of metal, but is not limited to metal as long as it has a predetermined strength, and may be made of resin, and is limited to metal. It is not something that is done. It should be noted that this shows an example of the clamp device of the present invention, and other modifications are also possible.

クランプ装置１は、基台部１０、ハンドル部１２、リンク部２０、押圧部３０、揺動部５０等で構成されている。基台部１０は、２枚の略Ｌ字状の板材が互いに所定間隔を隔てて向き合うように設けられたもので、クランプ装置１の全体を支えるものである。 The clamp device 1 is composed of a base portion 10, a handle portion 12, a link portion 20, a pressing portion 30, a swing portion 50, and the like. The base portion 10 is provided so that two substantially L-shaped plate members face each other at predetermined intervals, and supports the entire clamp device 1.

揺動部５０は、棒状で、一端である揺動部後端部５０ｂが基台部１０の後方上部に架け渡された軸ピン５２を介して基台部１０に軸支され、他端である揺動部前端部５０ａが上下方向に揺動自在に設けられたものである。 The swinging portion 50 has a rod shape, and the rear end portion 50b of the swinging portion, which is one end, is pivotally supported by the base portion 10 via a shaft pin 52 bridged over the rear upper portion of the base portion 10, and is supported at the other end. A swinging portion front end portion 50a is provided so as to be swingable in the vertical direction.

押圧部３０は、棒状で、揺動部５０の上方に、揺動部５０と平行且つ所定間隔を保持するように付勢された状態で設けられ、一端である押圧部前端部３０ａが物品を押圧して固定する押圧端となるものである。本実施の形態の例では、押圧部前端部３０ａに下方に伸びるボルト状の押圧部材３２を備え、押圧端として機能する押圧部材３２を介して物品を固定するようにしている。 The pressing portion 30 is rod-shaped and is provided above the swinging portion 50 in a state of being urged parallel to the rocking portion 50 and maintaining a predetermined interval, and the pressing portion front end portion 30a at one end holds an article. It is a pressing end that is pressed and fixed. In the example of the present embodiment, the front end portion 30a of the pressing portion is provided with a bolt-shaped pressing member 32 extending downward, and the article is fixed via the pressing member 32 that functions as the pressing end.

また、押圧部３０を、揺動部５０と平行且つ所定間隔を保持するように付勢された状態に配置する方法としては、特に、限定されるものではないが、本実施の形態の例では、揺動部５０から押圧部３０方向に平行する２本（２本以上でもよい）の摺動軸部材４０，４４が起立し、摺動軸部材４０，４４が押圧部３０に遊嵌され、揺動部５０と押圧部３０との間に、弾性部材であるバネ材４２，４６が配設されている構造となっている。摺動軸部材４０，４４は、ボルト状で、押圧部３０の貫通孔に挿入され、揺動部５０に螺嵌されており、揺動部５０と押圧部３０との間の摺動軸部材４０，４４にバネ材４２，４６が被設されている。尚、バネ材４２，４６に変わる弾性部材としては、スポンジ等がある。 Further, the method of arranging the pressing portion 30 in a state of being urged parallel to the swinging portion 50 and maintaining a predetermined interval is not particularly limited, but in the example of the present embodiment, the method is not particularly limited. , Two (or two or more) sliding shaft members 40, 44 parallel to the pressing portion 30 direction stand up from the swinging portion 50, and the sliding shaft members 40, 44 are loosely fitted into the pressing portion 30. The structure is such that spring members 42 and 46, which are elastic members, are arranged between the swinging portion 50 and the pressing portion 30. The sliding shaft members 40 and 44 are bolt-shaped, inserted into the through hole of the pressing portion 30, and screwed into the swinging portion 50, and the sliding shaft member between the swinging portion 50 and the pressing portion 30. Spring members 42 and 46 are installed on the 40 and 44. As an elastic member that replaces the spring materials 42 and 46, there is a sponge or the like.

尚、揺動部５０の他端（揺動部前端部５０ａ）が当接すると揺動部５０が水平になるように基台部１０に当接部材となる固着ピン５６が設けられている。揺動部５０が、固着ピン５６により水平になると、押圧部３０も揺動部５０と平行且つ所定間隔を保持するように付勢された状態で水平になる。 A fixing pin 56 serving as a contact member is provided on the base portion 10 so that the rocking portion 50 becomes horizontal when the other end of the rocking portion 50 (front end portion 50a of the rocking portion) comes into contact with the rocking portion 50. When the swinging portion 50 is leveled by the fixing pin 56, the pressing portion 30 is also leveled in a state of being urged to be parallel to the swinging portion 50 and to maintain a predetermined interval.

揺動部５０の当接部材である固着ピン５６に接する位置に固着部材５４である磁石を有し、当接部材である固着ピン５６が、固着部材５４に磁力で固着可能な材料である。尚、当接部材が、揺動部５０を所定期間保持する方法については、磁力に限られるものではなく、他の方法であってもよい。 A magnet that is a fixing member 54 is provided at a position in contact with the fixing pin 56 that is a contact member of the rocking portion 50, and the fixing pin 56 that is a contact member is a material that can be magnetically fixed to the fixing member 54. The method in which the contact member holds the swinging portion 50 for a predetermined period is not limited to the magnetic force, and may be another method.

ハンドル部１２は、ハンドル部本体部１４とハンドルバー１６との２つの部分からなり、ハンドル部本体部１４は、長方形の板材で、基台部１０の両側の外側から基台部１０を挟み込むように対置され、略Ｔ字状の板材であるハンドルバー１６が、ハンドル部本体部上端部１４ｂに挟み込まれた状態で、さらに上方に伸びて配置されている。そして、ハンドル部１２のハンドル部本体部１４のハンドル部本体部下端部１４ａが、基台部１０の前方下方に架け渡された軸ピン１８で軸支され、ハンドル部１２の上端であるハンドルバー１６が上下方向に揺動可能に開放された状態となっている。 The handle portion 12 is composed of two parts, a handle portion main body portion 14 and a handle bar 16, and the handle portion main body portion 14 is a rectangular plate material so as to sandwich the base portion 10 from the outside on both sides of the base portion 10. The handlebar 16 which is opposed to the handlebar 16 and is a substantially T-shaped plate material is arranged so as to extend further upward while being sandwiched between the upper end portion 14b of the handle portion main body portion. Then, the lower end portion 14a of the handle portion main body portion 14 of the handle portion main body portion 14 of the handle portion 12 is pivotally supported by the shaft pin 18 bridged to the front lower side of the base portion 10, and the handle bar which is the upper end of the handle portion 12 16 is in a state of being open so as to be swingable in the vertical direction.

リンク部２０は、押圧部３０とハンドル部１２とに端部が軸支された状態で、押圧部３０とハンドル部１２と接続するものである。リンク部２０は、２枚の長方形の板材で、リンク部下端部２０ａで押圧部３０の略中央を挟んだ状態で軸ピン２４で軸支され、また、リンク部下端部２０ａがハンドル部１２のハンドル部本体部上端部１４ｂ付近の内側に軸ピン２２で軸支されている。 The link portion 20 is connected to the pressing portion 30 and the handle portion 12 in a state where the end portions are pivotally supported by the pressing portion 30 and the handle portion 12. The link portion 20 is made of two rectangular plate members, and is pivotally supported by a shaft pin 24 with the lower end portion 20a of the link portion sandwiching the substantially center of the pressing portion 30, and the lower end portion 20a of the link portion is the handle portion 12. It is pivotally supported by a shaft pin 22 inside the vicinity of the upper end portion 14b of the handle portion main body portion.

次に、上述の構成のクランプ装置１の使用方法及び動作について説明する。まず、図１〜図３に示すように、ハンドル部１２が基台部１０に斜設され、揺動部５０が基台部１０に斜設されると共に押圧部３０も基台部１０に対して斜設され、側面視で、ハンドル部１２と、揺動部５０及び押圧部３０とが、略Ｖ字状に配置された状態から動作を説明する。 Next, the usage and operation of the clamp device 1 having the above configuration will be described. First, as shown in FIGS. 1 to 3, the handle portion 12 is obliquely provided on the base portion 10, the swing portion 50 is obliquely provided on the base portion 10, and the pressing portion 30 is also obliquely provided on the base portion 10. The operation will be described from a state in which the handle portion 12, the swing portion 50, and the pressing portion 30 are arranged in a substantially V shape in a side view.

この図１〜図３の状態から、図４〜図６に示すように、ハンドル部１２を起立させる方向に回動させると、リンク部２０が、押圧部３０を上方から押圧し、平行状態の押圧部３０及び揺動部５０が一体で回動する。 From the state of FIGS. 1 to 3, as shown in FIGS. 4 to 6, when the handle portion 12 is rotated in the upright direction, the link portion 20 presses the pressing portion 30 from above and is in a parallel state. The pressing portion 30 and the swinging portion 50 rotate integrally.

図４〜図６の状態からさらにハンドル部１２を回動させると、図７〜図９に示すように、揺動部５０が当接部材である固着ピン５６に当接して、揺動部５０及び押圧部３０が略水平になる。 When the handle portion 12 is further rotated from the state of FIGS. 4 to 6, as shown in FIGS. 7 to 9, the swing portion 50 comes into contact with the fixing pin 56 which is a contact member, and the swing portion 50 And the pressing portion 30 becomes substantially horizontal.

図７〜図９の状態からさらにハンドル部１２を回動させると、図１０〜図１２に示すように、リンク部２０が押圧部３０を押圧して、押圧部３０を揺動部５０から付勢力に反して水平状態を維持したまま降下させることになる。すなわち、リンク部２０によって押圧部３０が下方向に押され、揺動部５０が当接部材である固着ピン５６に当接してこれ以上下がらず、押圧部３０は、摺動軸部材４０，４４にガイドされる形でバネ材４２，４６が圧縮されて、揺動部５０と平行状態を保ったままで降下することになる。 When the handle portion 12 is further rotated from the state of FIGS. 7 to 9, the link portion 20 presses the pressing portion 30 and the pressing portion 30 is attached from the swinging portion 50 as shown in FIGS. 10 to 12. Contrary to the power, it will be lowered while maintaining the horizontal state. That is, the pressing portion 30 is pushed downward by the link portion 20, the swinging portion 50 abuts on the fixing pin 56 which is the abutting member, and the pressing portion 30 is not lowered any more, and the pressing portion 30 is the sliding shaft members 40, 44. The spring members 42 and 46 are compressed in a manner guided by the swinging portion 50, and descend while maintaining a parallel state with the swinging portion 50.

図１０〜図１２の状態からさらにハンドル部１２を回動させると、図１３〜図１５に示すように、押圧部３０が揺動部５０に密接して停止し、この状態で、押圧部３０の押圧端（押圧部材３２）が、物品を固定することになる。クランプ装置１の全体の動きとしては、押圧部３０が、揺動した後に下降することで、押圧部３０の押圧端（押圧部材３２）が、物品を固定する。 When the handle portion 12 is further rotated from the state of FIGS. 10 to 12, the pressing portion 30 stops in close contact with the swinging portion 50 as shown in FIGS. 13 to 15, and in this state, the pressing portion 30 The pressing end (pressing member 32) of the above will fix the article. As for the overall movement of the clamp device 1, the pressing portion 30 swings and then descends, so that the pressing end (pressing member 32) of the pressing portion 30 fixes the article.

尚、物品の固定を解除する場合には、図１３〜図１５の状態すなわち押圧部３０が揺動部５０に密接して停止し、押圧部３０の押圧端（押圧部材３２）が、物品を固定している状態で、ハンドル部１２を傾斜させる方向に回動させる。すると、リンク部２０による押圧部３０への加圧が弱まり、図１０〜図１２に示すように、押圧部３０が上昇する。このとき、揺動部５０は、揺動部５０に設けられた磁石である固着部材５４と固着ピン５６とが接着したままで、揺動しない。揺動部５０が揺動しない状態は、図７〜図９に示す、押圧部３０と揺動部５０とが当初所定間隔に平行して離間した状態になるまで続く。すなわち、当接部材である固着ピン５６が、押圧部３０が揺動部５０から離間して所定間隔になるまで、揺動部５０を保持することになる。押圧部３０の押圧端（押圧部材３２）が物品から離れた時、物品の固定自体は解除される。 When the article is released from being fixed, the state shown in FIGS. 13 to 15, that is, the pressing portion 30 stops in close contact with the swinging portion 50, and the pressing end (pressing member 32) of the pressing portion 30 presses the article. In the fixed state, the handle portion 12 is rotated in the tilting direction. Then, the pressure applied to the pressing portion 30 by the link portion 20 weakens, and as shown in FIGS. 10 to 12, the pressing portion 30 rises. At this time, the swinging portion 50 does not swing while the fixing member 54, which is a magnet provided in the swinging portion 50, and the fixing pin 56 remain adhered to each other. The state in which the swinging portion 50 does not swing continues until the pressing portion 30 and the swinging portion 50 are initially separated in parallel with a predetermined interval as shown in FIGS. 7 to 9. That is, the fixing pin 56, which is a contact member, holds the swinging portion 50 until the pressing portion 30 is separated from the swinging portion 50 and has a predetermined interval. When the pressing end (pressing member 32) of the pressing portion 30 is separated from the article, the fixing of the article itself is released.

そして、図７〜図９の状態から、ハンドル部１２をより傾斜する方向に回動させると、リンク部２０が押圧部３０を回動させることになり、押圧部３０の回動が始まると、揺動部５０が摺動軸部材４０を介して引き上げられるようになり、図４〜図６に示すように、揺動部５０が固着ピン５６から離れて、押圧部３０と平行した状態で揺動を始める。 Then, when the handle portion 12 is rotated in a more inclined direction from the state of FIGS. 7 to 9, the link portion 20 rotates the pressing portion 30, and when the rotation of the pressing portion 30 starts, the rotation of the pressing portion 30 is started. The swinging portion 50 is pulled up via the sliding shaft member 40, and as shown in FIGS. 4 to 6, the swinging portion 50 is separated from the fixing pin 56 and shaken in parallel with the pressing portion 30. Start moving.

さらにハンドル部１２をより傾斜する方向に回動させると、図１〜図３に示すように、当初の揺動部５０及び押圧部３０とが、完全に持ち上がった状態に戻る。 Further, when the handle portion 12 is rotated in a more inclined direction, as shown in FIGS. 1 to 3, the initial swing portion 50 and the pressing portion 30 return to a completely lifted state.

以上のようなクランプ装置１によれば、ハンドル部１２の円弧操作のみで、押圧部３０が、揺動した後に下降することで、押圧部３０の押圧端（押圧部材３２）が、物品を固定することで、揺動しつつ物品を挟むような動作を行いつつ、更に下方向に動作して強く押し込んで十分な保持力を発揮させることが可能である。 According to the clamp device 1 as described above, the pressing portion 30 swings and then descends only by operating the arc of the handle portion 12, so that the pressing end (pressing member 32) of the pressing portion 30 fixes the article. By doing so, it is possible to perform an action of pinching an article while swinging, and further move downward to push strongly and exert a sufficient holding force.

物品の辺縁部から奥まった位置に存在する穴にピンを入れて位置決めをしたい場合、従来のトグルクランプでは、最終的に真上からピンを穴に入れることができない。これに対して、クランプ装置１では、物品の外側に配置したクランプ装置１の押圧部前端部３０ａにピンを取付け、ハンドル部１２の円弧操作のみで、円弧運動により目的位置上部までピンを移動し、そこから真下に直動することで、穴にピンを入れることが可能になる。 When it is desired to insert a pin into a hole located deep from the edge of an article for positioning, the conventional toggle clamp cannot finally insert the pin into the hole from directly above. On the other hand, in the clamp device 1, a pin is attached to the front end portion 30a of the pressing portion of the clamp device 1 arranged on the outside of the article, and the pin is moved to the upper part of the target position by circular motion only by operating the arc of the handle portion 12. By moving straight down from there, it is possible to insert a pin into the hole.

以上のように、本発明によれば、ハンドル部の円弧操作のみで、揺動しつつ物品を挟むような動作を行いつつ、更に下方向に動作して強く押し込んで十分な保持力を発揮させることが可能なクランプ装置を提供することができる。 As described above, according to the present invention, only by operating the arc of the handle portion, while performing an action of pinching an article while swinging, it further moves downward and pushes strongly to exert a sufficient holding force. It is possible to provide a clamping device capable of providing a clamping device.
