The table 30 slides in the x direction of the arrow in FIG. 1 due to the force applied to the deburring tool 80. In the present embodiment, the tool holding portion 20 is arranged on the upper surface of the table 30 via a circular upper base plate 24 in a plan view. Further, a part of the components of the linear motion guide bearing 40 and the second magnet 51 are provided on the lower surface 34 of the table 30.

基部３１は、上記のテーブル３０に対して相対的に移動可能なもので、直方体の内部に空間を設けるとともにその上面３５が開放された箱形をなしている。この基部３１の内部には直動案内軸受４０及び第１磁石５０が設けられる。また、テーブル３０の下面３４に設けられた第２磁石５１も、基部３１の内部に納められる。 The base 31 is movable relative to the table 30, and has a box shape in which a space is provided inside the rectangular parallelepiped and the upper surface 35 thereof is open. A linear motion guide bearing 40 and a first magnet 50 are provided inside the base portion 31. Further, the second magnet 51 provided on the lower surface 34 of the table 30 is also housed inside the base 31.

直動案内軸受４０は、テーブル３０と基部３１とをスライド可能に連結するものであり、レール４１とキャリッジ４２とを備える。レール４１は、本実施形態では基部３１側に配置され、棒状のシャフトが２本、押圧装置１０の一の方向に沿って設けられる。キャリッジ４２は、レール４１が貫通される略円筒形の部材であり、レール４１に沿って移動する。本実施形態ではキャリッジ４２がテーブル３０の下面３４に設けられる。なお、直動案内軸受４０は、本実施形態に採用されている形態に限られず、公知の様々なものを採用することができる。 The linear motion guide bearing 40 slidably connects the table 30 and the base 31, and includes a rail 41 and a carriage 42. In the present embodiment, the rail 41 is arranged on the base 31 side, and two rod-shaped shafts are provided along one direction of the pressing device 10. The carriage 42 is a substantially cylindrical member through which the rail 41 is passed, and moves along the rail 41. In this embodiment, the carriage 42 is provided on the lower surface 34 of the table 30. The linear motion guide bearing 40 is not limited to the form adopted in this embodiment, and various known bearings can be adopted.

また、本実施形態では、基部３１側にレール４１、テーブル３０側にキャリッジ４２を配置しているが、レール４１とキャリッジ４２の取付に取付金具等を用いる、又は基部３１とテーブル３０の位置関係を上下反対にすること等でテーブル３０側にレール４１、基部３１側にキャリッジ４２を配置してもよい。この直動案内軸受４０によって、テーブル３０と基部３１とが相対的に、例えばＸ軸方向（図１及び図２の矢印ｘ方向）にスライド可能となる。 Further, in the present embodiment, the rail 41 is arranged on the base 31 side and the carriage 42 is arranged on the table 30 side, but a mounting bracket or the like is used for mounting the rail 41 and the carriage 42, or the positional relationship between the base 31 and the table 30. The rail 41 may be arranged on the table 30 side and the carriage 42 may be arranged on the base 31 side by turning the above upside down. The linear motion guide bearing 40 allows the table 30 and the base 31 to slide relatively, for example, in the X-axis direction (arrow x direction in FIGS. 1 and 2).

第１磁石５０は、直動案内軸受４０のレール４１の一端側４３及び他端側４４に設けられる磁石であり、本実施形態では、基部３１に２つ設けられる。この第１磁石５０が配置される場所であるが、レール４１そのものに設ける必要はなく、レール４１の一端及び他端が配置される構成部品又はその近傍に設けられればよい。本実施形態では、基部３１の内壁に窪み３２を設け、その窪み３２に第１磁石５０を埋設している。 The first magnet 50 is a magnet provided on one end side 43 and the other end side 44 of the rail 41 of the linear motion guide bearing 40, and in this embodiment, two magnets are provided on the base 31. Although this is the place where the first magnet 50 is arranged, it is not necessary to provide it on the rail 41 itself, and it may be provided on the component component on which one end and the other end of the rail 41 are arranged or in the vicinity thereof. In the present embodiment, a recess 32 is provided in the inner wall of the base 31, and the first magnet 50 is embedded in the recess 32.

第２磁石５１は、直動案内軸受４０のキャリッジ４２側に配置される磁石であり、本実施形態では、テーブル３０の下面３４にブラケット５２を介して吊下げる形で設けられる。この第２磁石５１も、キャリッジ４２そのものに設ける必要はなく、キャリッジ４２が配置される構成部品又はその近傍に設けられればよい。 The second magnet 51 is a magnet arranged on the carriage 42 side of the linear motion guide bearing 40, and is provided in the form of being suspended from the lower surface 34 of the table 30 via the bracket 52 in the present embodiment. The second magnet 51 does not have to be provided on the carriage 42 itself, but may be provided on or near the component in which the carriage 42 is arranged.

また、第１磁石５０と第２磁石５１の極性であるが、第１磁石５０と第２磁石５１とは互いに反発する極性に配置され、２つの第１磁石５０に挟まれた第２磁石５１が、第１磁石５０との反発力によって２つの第１磁石５０の略中間に位置するようにされる。 Further, regarding the polarities of the first magnet 50 and the second magnet 51, the first magnet 50 and the second magnet 51 are arranged at polarities that repel each other, and the second magnet 51 sandwiched between the two first magnets 50. Is positioned approximately in the middle of the two first magnets 50 due to the repulsive force with the first magnet 50.

ここで、図５及び図６を参照して、第１磁石と第２磁石との距離を変更可能として、第１磁石と第２磁石との反発力を調整する調整機構６０ａ，６０ｂ，６０ｃ，６０ｄについて説明する。上述の図１ないし図４に示す押圧装置１０では、第１磁石５０と第２磁石５１との反発力を調整するには、第１磁石５０と第２磁石５１そのものを磁力の異なる物に交換するしかなかった。そこで、これから説明する調整機構６０ａ，６０ｂ，６０ｃ，６０ｄを設けることにより、押圧装置１０に設けられたバリ取り工具８０の押圧力を容易に調整することができるようになる。 Here, with reference to FIGS. 5 and 6, adjustment mechanisms 60a, 60b, 60c, which make it possible to change the distance between the first magnet and the second magnet and adjust the repulsive force between the first magnet and the second magnet, 60d will be described. In the pressing device 10 shown in FIGS. 1 to 4 described above, in order to adjust the repulsive force between the first magnet 50 and the second magnet 51, the first magnet 50 and the second magnet 51 themselves are replaced with objects having different magnetic forces. I had no choice but to do it. Therefore, by providing the adjusting mechanisms 60a, 60b, 60c, and 60d described below, the pressing force of the deburring tool 80 provided in the pressing device 10 can be easily adjusted.

先ずは、図５を参照して、第１磁石５０ａ，５０ｂの位置を変更する形態を説明する。図５（Ａ）（Ｂ）は、テーブル３０を取外した基部３１ａ，３１ｂを、その開放された上面から見た図である。なお、第１磁石５０ａ，５０ｂと第２磁石５１との位置関係を見易くするために、第２磁石５１を破線で表す。図５（Ａ）（Ｂ）に示す調整機構６０ａ，６０ｂは、いずれも第１磁石５０ａ，５０ｂに接続される軸体６１ａ，６１ｂと、軸体６１ａ，６１ｂが貫通されるために基部３１ａ，３１ｂの側壁に設けられた取付孔６２ａ，６２ｂと、軸体６１ａ，６１ｂと取付孔６２ａ，６２ｂとを所望する複数の位置で係止可能な係止部とを備えるものである。 First, a mode of changing the positions of the first magnets 50a and 50b will be described with reference to FIG. 5 (A) and 5 (B) are views of the bases 31a and 31b from which the table 30 has been removed as viewed from the open top surface thereof. The second magnet 51 is represented by a broken line in order to make it easier to see the positional relationship between the first magnets 50a and 50b and the second magnet 51. In the adjustment mechanisms 60a and 60b shown in FIGS. 5A and 5B, the shaft bodies 61a and 61b connected to the first magnets 50a and 50b and the bases 31a and 61b are penetrated through the shaft bodies 61a and 61b. It is provided with mounting holes 62a and 62b provided on the side wall of 31b, and locking portions capable of locking the shaft bodies 61a and 61b and the mounting holes 62a and 62b at a desired plurality of positions.

そして、図の右側に示す第１磁石５０ａ，５０ｂは、第２磁石５１との距離を縮めた状態のものであり、図の左側に示す第１磁石５０ａ，５０ｂは、第２磁石５１との距離を広くした状態のものである。このように、左右の第１磁石５０ａ，５０ｂを独立して調整可能なため、例えば、図５（Ａ）（Ｂ）に示すように、２つの第１磁石５０ａ，５０ｂを基部３１ａ，３１ｂの左側に寄せて、テーブル３０の中立位置を左側に調整することもできる。 The first magnets 50a and 50b shown on the right side of the figure are in a state where the distance from the second magnet 51 is shortened, and the first magnets 50a and 50b shown on the left side of the figure are with the second magnet 51. It is in a state where the distance is widened. Since the left and right first magnets 50a and 50b can be adjusted independently in this way, for example, as shown in FIGS. 5A and 5B, the two first magnets 50a and 50b are attached to the bases 31a and 31b. The neutral position of the table 30 can be adjusted to the left side by moving it to the left side.

図５（Ａ）に示す調整機構６０ａをさらに説明する。この調整機構６０ａは、軸体６１ａにボルトを採用し、係止部にはボルト６１ａに設けられた雄ねじ６４と、取付孔６２ａに設けられた雌ねじ６５を用いる。通常は、ロックナット６３によって、ボルト６１ａは固定されている。調整時には、ロックナット６３を緩め、ボルト６１ａを回動させて、第１磁石５０ａを任意の位置に移動させればよい。そして、第１磁石５０ａの位置が決まればロックナット６３を締めてボルト６１ａを固定する。 The adjustment mechanism 60a shown in FIG. 5A will be further described. In this adjusting mechanism 60a, a bolt is adopted for the shaft body 61a, and a male screw 64 provided in the bolt 61a and a female screw 65 provided in the mounting hole 62a are used for the locking portion. Normally, the bolt 61a is fixed by the lock nut 63. At the time of adjustment, the locknut 63 may be loosened, the bolt 61a may be rotated, and the first magnet 50a may be moved to an arbitrary position. Then, when the position of the first magnet 50a is determined, the lock nut 63 is tightened to fix the bolt 61a.

図５（Ｂ）に示す調整機構６０ｂでは、係止部として、軸体６１ｂの途中に突起６６が設けられ、取付孔６２ｂには前記突起６６が通過するための溝６７が設けられる。そして、図の右側に示す状態では、突起６６と軸体６１ｂの頭部６８とで基部３１ｂの側壁３３ｂを挟んで、第１磁石５０ｂを第２磁石５１に近づけた状態で固定する。一方、図の左側に示す状態では、突起６６と第１磁石５０ｂとで基部３１の側壁３３ｂを挟んで、第１磁石５０ｂを第２磁石５１から遠ざけた状態で固定する。 In the adjusting mechanism 60b shown in FIG. 5B, a protrusion 66 is provided in the middle of the shaft body 61b as a locking portion, and a groove 67 for passing the protrusion 66 is provided in the mounting hole 62b. Then, in the state shown on the right side of the figure, the side wall 33b of the base portion 31b is sandwiched between the protrusion 66 and the head portion 68 of the shaft body 61b, and the first magnet 50b is fixed in a state of being close to the second magnet 51. On the other hand, in the state shown on the left side of the figure, the side wall 33b of the base 31 is sandwiched between the protrusion 66 and the first magnet 50b, and the first magnet 50b is fixed in a state of being away from the second magnet 51.

次に、図６を参照して、第２磁石５１ｃ，５１ｄの位置を変更する形態を説明する。図６（Ａ）（Ｂ）は、上部ベース板２４を取外した状態のテーブル３０ｃ，３０ｄを、上面から見た図である。図６（Ａ）（Ｂ）に示す調整機構６０ｃ，６０ｄは、テーブル３０ｃ，３０ｄに設けられたＸ軸方向の長孔７０ｃ，７０ｄと、前記長孔７０ｃ，７０ｄを貫通して、第２磁石５１ｃ，５１ｄを吊下げているブラケット５２ｃ，５２ｄに螺合される固定ボルト７１ｃ，７１ｄとを備える。そして、固定ボルト７１ｃ，７１ｄを緩めて第２磁石５１ｃ，５１ｄを長孔７０ｃ，７０ｄの範囲で移動させ、次に固定ボルト７１ｃ，７１ｄを締めてブラケット５２ｃ，５２ｄを固定すればよい。 Next, with reference to FIG. 6, a mode for changing the positions of the second magnets 51c and 51d will be described. 6 (A) and 6 (B) are views of the tables 30c and 30d with the upper base plate 24 removed, as viewed from above. The adjusting mechanisms 60c and 60d shown in FIGS. 6A and 6B pass through the elongated holes 70c and 70d in the X-axis direction provided on the tables 30c and 30d and the elongated holes 70c and 70d, and are the second magnets. It includes fixing bolts 71c and 71d that are screwed into the brackets 52c and 52d that suspend the 51c and 51d. Then, the fixing bolts 71c and 71d may be loosened to move the second magnets 51c and 51d within the range of the elongated holes 70c and 70d, and then the fixing bolts 71c and 71d may be tightened to fix the brackets 52c and 52d.

図６（Ａ）に示す調整機構６０ｃをさらに説明する。この調整機構６０ｃは、１つの第２磁石５１ｃ、及び第２磁石５１ｃを吊下げるブラケット５２ｃを備える。このため、第２磁石５１ｃの位置を調整することによって、テーブル３０ｃの中立位置を調整することができる。 The adjustment mechanism 60c shown in FIG. 6A will be further described. The adjusting mechanism 60c includes one second magnet 51c and a bracket 52c for suspending the second magnet 51c. Therefore, by adjusting the position of the second magnet 51c, the neutral position of the table 30c can be adjusted.

図６（Ｂ）に示す調整機構６０ｄでは、第２磁石５１ｄ、第２磁石５１ｄを吊下げるブラケット５２ｄ、長孔７０ｄ、及び固定ボルト７１ｄを２セットずつ備えている。そして、２つの第２磁石５１ｄの位置を、をそれぞれ個別に調整することができる。このため、上記のテーブルの中立位置に加えて、第１磁石５０との反発力の調整もすることができる。なお、図６（Ｂ）では、第２磁石５１ｄを図の左側に寄せた状態を示している。 The adjusting mechanism 60d shown in FIG. 6B includes two sets of a second magnet 51d, a bracket 52d for suspending the second magnet 51d, a long hole 70d, and a fixing bolt 71d. Then, the positions of the two second magnets 51d can be individually adjusted. Therefore, in addition to the neutral position of the above table, the repulsive force with the first magnet 50 can be adjusted. Note that FIG. 6B shows a state in which the second magnet 51d is moved to the left side of the figure.

次に、図７及び図８を参照して、第１磁石５０の他の実施例を説明する。図７（Ａ）は、図１ないし図４に示す押圧装置１０に用いられている第１磁石５０及び第２磁石５１の配置を模式的に表わした図、図７（Ｂ）は第１磁石５０を左右でそれぞれ２つ設けた形態を模式的に表した図、図７（Ｃ）は図７（Ｂ）の側面図、図７（Ｄ）は第１磁石５０を左右それぞれで４つ設けた形態の側面図である。図８（Ａ）（Ｂ）は第１磁石５０を左右でそれぞれ２つ設けた他の形態を模式的に表した図である。なお、図中のｓは磁石のＳ極、ｎはＮ極を表すが、この極性は、第１磁石５０と第２磁石５１とが互いに反発する極性であればこれに限られない。また、左右の第１磁石５０の間の距離が長い場合は、第２磁石５１を複数設けることもできる。 Next, another embodiment of the first magnet 50 will be described with reference to FIGS. 7 and 8. 7 (A) is a diagram schematically showing the arrangement of the first magnet 50 and the second magnet 51 used in the pressing device 10 shown in FIGS. 1 to 4, and FIG. 7 (B) is the first magnet. A diagram schematically showing a form in which two 50s are provided on the left and right sides, FIG. 7C is a side view of FIG. 7B, and FIG. 7D is provided with four first magnets 50 on each of the left and right sides. It is a side view of the form. 8 (A) and 8 (B) are views schematically showing another form in which two first magnets 50 are provided on the left and right sides, respectively. In the figure, s represents the S pole of the magnet and n represents the N pole, but the polarity is not limited to this as long as the polarities of the first magnet 50 and the second magnet 51 repel each other. Further, when the distance between the left and right first magnets 50 is long, a plurality of second magnets 51 may be provided.

先ず、図７（Ａ）に示す形態を説明する。この形態は図１ないし図４で既に述べたものであり、図の左右方向に１つずつの第１磁石５０が配置され、その中央に第２磁石５１が配置される。そして、第１磁石５０と第２磁石５１の軸ａ１は同一線上にある。この形態では構成が簡素になるという利点がある。しかし、第２磁石５１が移動して一方の第１磁石５０に近づくにつれ、第１磁石５０と第２磁石５１の反発力が強まり、結果としてバリ取り工具８０を被加工物８３に押圧する力が増加してしまう。そこで、図７（Ｂ）及び図８（Ａ）（Ｂ）に示すように第１磁石５０を配置することで、第２磁石５１の位置に関わらず、第１磁石５０との反発力を略一定にするのである。 First, the form shown in FIG. 7 (A) will be described. This form has already been described in FIGS. 1 to 4, and one first magnet 50 is arranged in the left-right direction of the figure, and a second magnet 51 is arranged in the center thereof. The axes a1 of the first magnet 50 and the second magnet 51 are on the same line. This form has the advantage of simplifying the configuration. However, as the second magnet 51 moves and approaches one of the first magnets 50, the repulsive force between the first magnet 50 and the second magnet 51 becomes stronger, and as a result, the force that presses the deburring tool 80 against the workpiece 83. Will increase. Therefore, by arranging the first magnet 50 as shown in FIGS. 7 (B) and 8 (A) (B), the repulsive force with the first magnet 50 is abbreviated regardless of the position of the second magnet 51. Make it constant.

図７（Ｂ）に示す形態は、左右の第１磁石５０がそれぞれ複数設けられ、それぞれ複数の第１磁石５０の軸ａ２が第２磁石５１の軸ａ１に対して離間して配置されているものである。なお、図７（Ｃ）に示すように、ここでは第１磁石５０を左右に２つずつ配置しているが、例えば、図７（Ｄ）に示すように、第１磁石５０を左右に４つずつ配置する等してもよく、第１磁石５０の数は特に限定されない（図８（Ａ）（Ｂ）に示す形態においても同様。）。 In the form shown in FIG. 7B, a plurality of left and right first magnets 50 are provided, and the axes a2 of the plurality of first magnets 50 are arranged apart from the axis a1 of the second magnet 51. It is a thing. As shown in FIG. 7 (C), two first magnets 50 are arranged on the left and right, but for example, as shown in FIG. 7 (D), the first magnets 50 are arranged on the left and right. The number of the first magnets 50 may be arranged one by one, and the number of the first magnets 50 is not particularly limited (the same applies to the modes shown in FIGS. 8A and 8B).

図８（Ａ）に示す形態は、図７（Ｂ）に示す形態から、第１磁石５０の軸ａ３を、第２磁石５１より離れるに従い、第２磁石５１の軸ａ１から互いに広がるように配置したものである。また、図８（Ｂ）に示す形態は、図８（Ａ）に示す形態から、さらに第１磁石５０の軸ａ４が広がるように、第２磁石５１の軸ａ１と直交する方向に第１磁石５０の軸ａ４を配置したものである。 In the form shown in FIG. 8A, the axis a3 of the first magnet 50 is arranged so as to spread from the axis a1 of the second magnet 51 as the distance from the second magnet 51 increases from the form shown in FIG. 7B. It was done. Further, the form shown in FIG. 8B is different from the form shown in FIG. 8A in a direction orthogonal to the axis a1 of the second magnet 51 so that the axis a4 of the first magnet 50 further expands. The axis a4 of 50 is arranged.

なお、図７（Ｂ）及び図８（Ａ）（Ｂ）に示す形態では、第１磁石５０の配置によっては、第２磁石５１が第１磁石５０に近付きすぎたときに、第１磁石５０と第２磁石５１との反発力が失われてしまう場合がある。この様な場合、第１磁石５０と第２磁石５１との距離が短くなりすぎることを防止するストッパー等（図示せず）を、適宜設けることが好ましい。 In addition, in the form shown in FIGS. 7 (B) and 8 (A) (B), depending on the arrangement of the first magnet 50, when the second magnet 51 gets too close to the first magnet 50, the first magnet 50 And the repulsive force between the second magnet 51 and the second magnet 51 may be lost. In such a case, it is preferable to appropriately provide a stopper or the like (not shown) for preventing the distance between the first magnet 50 and the second magnet 51 from becoming too short.

図１ないし図４に戻り、脚部２５は、基部３１の下側に設けられ、押圧装置１０全体をロボット等も含めたバリ取り装置のベッド（図示せず）に固定するものである。 Returning to FIGS. 1 to 4, the leg portion 25 is provided on the lower side of the base portion 31 and fixes the entire pressing device 10 to the bed (not shown) of the deburring device including the robot and the like.

次に、上述した本実施形態の押圧装置１０の構成要素を踏まえて、図１及び図２を参照しながら押圧装置１０の基本的な動作及び使用方法を説明する。 Next, based on the above-described components of the pressing device 10 of the present embodiment, the basic operation and usage of the pressing device 10 will be described with reference to FIGS. 1 and 2.

先ず、押圧装置１０の非稼働時には、第１磁石５０と第２磁石５１との反発力によって、第２磁石５１がレール４１の一端側４３の第１磁石５０と他端側４４の第１磁石５０との中間位置にあり、テーブル３０は中立位置に保たれている。次に、図１及び図２に示すように、図示しないロボットにより被加工物８３が把持されて、被加工物８３の稜線がバリ取り工具８０の刃物８１に当接されると、バリ取り工具８０が押されて、テーブル３０が図のＸ軸のうち右側に移動する。すると、図の右側の第１磁石５０と、テーブル３０側に設けられた第２磁石５１との反発力が強まり、その反発力によってバリ取り工具８０の刃物８１が被加工物８３に押圧される。 First, when the pressing device 10 is not in operation, the repulsive force between the first magnet 50 and the second magnet 51 causes the second magnet 51 to be the first magnet 50 on one end side 43 of the rail 41 and the first magnet on the other end side 44. It is in an intermediate position with 50, and the table 30 is kept in a neutral position. Next, as shown in FIGS. 1 and 2, when the workpiece 83 is gripped by a robot (not shown) and the ridgeline of the workpiece 83 comes into contact with the blade 81 of the deburring tool 80, the deburring tool 80 is pushed and the table 30 moves to the right of the X-axis in the figure. Then, the repulsive force between the first magnet 50 on the right side of the figure and the second magnet 51 provided on the table 30 side is strengthened, and the repulsive force presses the blade 81 of the deburring tool 80 against the workpiece 83. ..

次に、ロボットにより、被加工物８３が図２のＹ軸方向に移動される。すると、被加工物８３の稜線には凹凸部８４が設けられているのであるが、その凹凸部８４にバリ取り工具８０の刃物８１がさしかかると、テーブル３０が中立位置に戻ろうとすることでＸ軸方向のうち図の左側に移動する。このため、刃物８１が凹凸部８４に倣って移動し、常に刃物８１を被加工物８３の稜線に押圧して当接させることができる。これにより、被加工物８３の凹凸部８４に合わせたロボットの細かな教示が不要となり、生産現場での省力化を図ることができる。 Next, the work piece 83 is moved in the Y-axis direction of FIG. 2 by the robot. Then, the uneven portion 84 is provided on the ridgeline of the workpiece 83, but when the blade 81 of the deburring tool 80 approaches the uneven portion 84, the table 30 tries to return to the neutral position, so that X Move to the left side of the figure in the axial direction. Therefore, the blade 81 moves following the uneven portion 84, and the blade 81 can always be pressed against the ridgeline of the workpiece 83 to be brought into contact with the blade 81. This eliminates the need for detailed instruction of the robot according to the uneven portion 84 of the workpiece 83, and can save labor at the production site.

また、本実施形態の押圧装置１０では、テーブル３０を中立位置から図１の左右両方向に動かすことができる。このため、バリ取り工具８０の刃物８１に、図１の右側方向から被加工物８３を当接させて、テーブル３０を中立位置から左側に移動させることもできる。 Further, in the pressing device 10 of the present embodiment, the table 30 can be moved from the neutral position in both the left and right directions of FIG. Therefore, the work piece 83 can be brought into contact with the blade 81 of the deburring tool 80 from the right side of FIG. 1, and the table 30 can be moved from the neutral position to the left side.

［第２実施形態］
次に、図９を参照して、他の実施形態に係る押圧装置１１０を説明する。なお、本図では内部の構成を分かりやすくするため、基部３１ｘ，３１ｙ及び第１磁石５０ｘ，５０ｙを破線で表す。 [Second Embodiment]
Next, the pressing device 110 according to another embodiment will be described with reference to FIG. 9. In this figure, the bases 31x, 31y and the first magnets 50x, 50y are represented by broken lines in order to make the internal configuration easy to understand.

本実施形態の押圧装置１１０では、テーブル３０ｘ、基部３１ｘ、直動案内軸受４０ｘ、第１磁石５０ｘ、第２磁石５１ｘを備えるＸ軸用押圧ユニット１１と、同じくテーブル３０ｙ、基部３１ｙ、直動案内軸受４０ｙ、第１磁石５０ｙ、第２磁石５１ｙを備えるＹ軸用押圧ユニット１２とを備える。これらのＸ軸用押圧ユニット１１とＹ軸用押圧ユニット１２は、その構成は同じであり、内部の直動案内軸受４０ｘ，４０ｙの方向がそれぞれＸ軸とＹ軸に沿った方向に設けられている。 In the pressing device 110 of the present embodiment, the X-axis pressing unit 11 including the table 30x, the base 31x, the linear motion guide bearing 40x, the first magnet 50x, and the second magnet 51x, and the table 30y, the base 31y, and the linear motion guiding A Y-axis pressing unit 12 including a bearing 40y, a first magnet 50y, and a second magnet 51y is provided. The X-axis pressing unit 11 and the Y-axis pressing unit 12 have the same configuration, and the directions of the internal linear motion guide bearings 40x and 40y are provided along the X-axis and the Y-axis, respectively. There is.

そして、Ｙ軸用押圧ユニット１２のテーブル３０ｙに、Ｘ軸用押圧ユニット１１の基部３１ｘを重ねる。さらに、Ｙ軸用押圧ユニット１２の基部３１ｙの下面に脚部２５（図示せず）を設け、Ｘ軸用押圧ユニット１１のテーブル３０ｘにバリ取り工具８０を保持した工具保持部２０（図示せず）を設ける。このように、２つの押圧ユニットを、それぞれの直動案内軸受４０ｘ，４０ｙの軸が直交する方向に重ねることより、Ｘ軸とＹ軸の２軸方向にバリ取り工具８０を移動させることが可能となる。 Then, the base portion 31x of the X-axis pressing unit 11 is superposed on the table 30y of the Y-axis pressing unit 12. Further, a tool holding portion 20 (not shown) in which a leg portion 25 (not shown) is provided on the lower surface of the base portion 31y of the Y-axis pressing unit 12 and a deburring tool 80 is held on the table 30x of the X-axis pressing unit 11. ) Is provided. In this way, by stacking the two pressing units in the directions in which the axes of the linear motion guide bearings 40x and 40y are orthogonal to each other, it is possible to move the deburring tool 80 in the two axial directions of the X axis and the Y axis. Will be.

［第３実施形態］
次に、図１０を参照して、さらに他の実施形態に係る押圧装置２１０を説明する。なお、上述の第１実施形態と構成が同じ箇所には同じ符号を付して、その説明を省略する。 [Third Embodiment]
Next, with reference to FIG. 10, the pressing device 210 according to still another embodiment will be described. The same reference numerals are given to the parts having the same configuration as that of the first embodiment described above, and the description thereof will be omitted.

本実施形態の押圧装置２１０は、テーブル３０、基部３１、直動案内軸受４０、第１磁石５０、第２磁石５１を備えるが、第１磁石５０が、直動案内軸受４０のレール４１の一端側４３のみに設けられている。また、基部３１のうち、レール４１の他端側４４には、キャリッジ４２又は第２磁石５１がそれ以上図の左側に移動しないようストッパー４５が設けられる。このため、第１磁石５０と第２磁石５１との反発力によって、非稼働時にはテーブル３０がレール４１の他端側４４の位置に保たれる。そして、被加工物８３がバリ取り工具８０の刃物８１に当接されると、図中の矢印方向にテーブル３０が移動し、第１磁石５０と第２磁石５１との反発力に応じた力で押圧される。 The pressing device 210 of the present embodiment includes a table 30, a base 31, a linear motion guide bearing 40, a first magnet 50, and a second magnet 51, and the first magnet 50 is one end of a rail 41 of the linear motion guide bearing 40. It is provided only on the side 43. Further, on the other end side 44 of the rail 41 of the base portion 31, a stopper 45 is provided so that the carriage 42 or the second magnet 51 does not move further to the left side in the figure. Therefore, the repulsive force between the first magnet 50 and the second magnet 51 keeps the table 30 at the position of the other end side 44 of the rail 41 when not in operation. Then, when the workpiece 83 comes into contact with the blade 81 of the deburring tool 80, the table 30 moves in the direction of the arrow in the drawing, and the force corresponding to the repulsive force between the first magnet 50 and the second magnet 51. Is pressed with.

以上、説明したように、本実施形態の押圧装置によれば、直動案内軸受によってテーブルがスライド可能となっている。このため、被加工物をバリ取り工具に当接させ、バリ取りをしたい方向に移動させると、被加工物の凹凸部に合わせてテーブルがスライドし、被加工物を把持するロボットの細かな教示が不要となる。 As described above, according to the pressing device of the present embodiment, the table can be slid by the linear motion guide bearing. For this reason, when the work piece is brought into contact with the deburring tool and moved in the direction in which deburring is desired, the table slides according to the uneven portion of the work piece, and the robot grips the work piece in detail. Is unnecessary.

また、バリ取り時には、第１磁石と第２磁石との反発力によって、バリ取り工具を被加工物に押圧するため、圧縮空気や電気等の動力を必要とせず、省エネルギー性に優れる。一方、非稼働時には、第１磁石と第２磁石との斥力によって、必然的にテーブルが中立位置に保たれる。さらに、テーブルは前記中立位置から直動案内軸受のレールの一端側又は他端側のいずれにも移動可能となる。このテーブルが双方向へ移動可能となることで、ロボットによる被加工物の持ち替えをすることなく、被加工物の多面のバリ取りが可能となり、生産効率を向上させることができる。 Further, at the time of deburring, the deburring tool is pressed against the workpiece by the repulsive force between the first magnet and the second magnet, so that power such as compressed air and electricity is not required, and energy saving is excellent. On the other hand, when not in operation, the repulsive force between the first magnet and the second magnet inevitably keeps the table in the neutral position. Further, the table can be moved from the neutral position to either one end side or the other end side of the rail of the linear motion guide bearing. Since this table can be moved in both directions, it is possible to deburr multiple surfaces of the workpiece without having to change the workpiece by a robot, and it is possible to improve production efficiency.

また、バリ取り工具を被加工物に当接させる押圧力の調整は、第１磁石及び第２磁石を磁力の異なるものに変更することで調整することができる。さらに、第１磁石又は第２磁石の位置を調整可能とする調整機構を備える構成では、より容易に押圧力の調整とテーブルの中立位置の調整が可能となる。 Further, the pressing force for bringing the deburring tool into contact with the workpiece can be adjusted by changing the first magnet and the second magnet to those having different magnetic forces. Further, in the configuration provided with the adjusting mechanism capable of adjusting the position of the first magnet or the second magnet, the pressing force can be adjusted and the neutral position of the table can be adjusted more easily.

また、第１磁石を左右それぞれ複数備え、それぞれの第１磁石の軸を離間させる構成では、第２磁石が移動して一方の第１磁石との距離が縮まっても、第１磁石と第２磁石との反発力の変化が少ない。これにより、テーブルの位置によってバリ取り工具を被加工物に当接させる押圧力が変化することがなく、被加工物に凹凸部があってもバリ取り又は面取りの幅を略一定とすることができる。 Further, in the configuration in which a plurality of first magnets are provided on each of the left and right sides and the axes of the first magnets are separated from each other, even if the second magnet moves and the distance between the first magnet and the first magnet is shortened, the first magnet and the second magnet are separated. There is little change in the repulsive force with the magnet. As a result, the pressing force that brings the deburring tool into contact with the workpiece does not change depending on the position of the table, and the width of deburring or chamfering can be made substantially constant even if the workpiece has irregularities. can.

また、第２実施形態である、Ｘ軸用押圧ユニット及びＹ軸用押圧ユニットを備える構成では、２軸にバリ取り工具を移動させることが可能となり、被加工物の細かな凹凸部にも対応させることができる。また、ロボットによる被加工物の持ち替えを、より少なくすることができる。 Further, in the configuration provided with the X-axis pressing unit and the Y-axis pressing unit, which is the second embodiment, it is possible to move the deburring tool to the two axes, and it is possible to deal with fine uneven portions of the workpiece. Can be made to. In addition, it is possible to reduce the number of changes in the workpiece by the robot.

また、第３実施形態である、第１磁石をレールの一端側のみに設ける構成では、部品点数を省略して、押圧装置の構成を簡素なものとすることができる。 Further, in the configuration in which the first magnet is provided only on one end side of the rail, which is the third embodiment, the number of parts can be omitted and the configuration of the pressing device can be simplified.

なお、上述の押圧装置は本発明の例示であり、発明の趣旨を逸脱しない範囲において、その構成を適宜変更することができる。 The above-mentioned pressing device is an example of the present invention, and its configuration can be appropriately changed without departing from the spirit of the invention.
