When the coolant adhering to the work 16 falls and adheres to the right side surface of the machine tool 1 above the first guide portion 41, the coolant reaches the first guide portion 41, and the first plate portion 41a It moves downward along the second plate portion 41 b and drops into the second guiding portion 42 from the lower end of the second plate portion 41 b. The coolant spreads at the bottom plate portion 42a. Since the weir 42b restricts the movement of the cooling fluid in the left-right direction, the cooling fluid moves toward the front end or the rear end of the bottom plate portion 42a. The coolant drops from the front end portion or the rear end portion of the bottom plate portion 42 a and reaches the receiving portion 50. The coolant is discharged through the discharge pipe 50b. The upper surface of the receiving portion 50 may be inclined downward toward the discharge pipe 50b.

ワーク１６に付着した冷却液が第三案内部２３に落下した場合、冷却液は第三案内部２３の底面を前方に移動する。堰２３ｂが冷却液の移動を制限するので、冷却液は排液筒２３ａに集まり、排液筒２３ａを通って落下し、受け部５０に至る。なお第三案内部２３の底面は、後側が前側よりも下になるように傾斜してもよい。この場合、排液筒２３ａは、第三案内部２３の底面の後縁部に位置する。   When the coolant adhering to the work 16 falls to the third guide portion 23, the coolant moves forward on the bottom surface of the third guide portion 23. Since the weir 23 b restricts the movement of the cooling fluid, the cooling fluid collects in the drainage cylinder 23 a, falls through the drainage cylinder 23 a, and reaches the receiving unit 50. The bottom surface of the third guide portion 23 may be inclined so that the rear side is lower than the front side. In this case, the drainage cylinder 23 a is located at the rear edge of the bottom surface of the third guiding portion 23.

実施の形態１に係る工作装置にあっては、開閉扉１３の下方に配置された第一案内部４１及び第二案内部４２によって、冷却液は、受け部５０に向けて移動する。故に冷却液が床を汚染することを防止できる。   In the machine tool according to the first embodiment, the coolant moves toward the receiver 50 by the first guide 41 and the second guide 42 disposed below the open / close door 13. Therefore, the coolant can be prevented from contaminating the floor.

ワークが開閉扉１３を通る時にワークから落下した冷却液が工作機械１の壁面に付着した場合、冷却液は、第一案内部４１によって、工作機械の壁面とワーク交換装置２０の間、即ち第二案内部４２に向けて落下する。冷却液は、第二案内部４２によって、受け部５０に向けて移動する。   When the coolant dropped from the workpiece as it passes through the opening / closing door 13 adheres to the wall surface of the machine tool 1, the coolant flows between the wall surface of the machine tool and the workpiece changer 20 by the first guide portion 41, ie The second guide 42 is dropped. The coolant moves toward the receiving unit 50 by the second guiding unit 42.

第一案内部４１は第二案内部４２に向けて下降傾斜するので、冷却液は第一案内部４１から第二案内部４２に向けて流下する。   Since the first guiding portion 41 is inclined downward toward the second guiding portion 42, the coolant flows from the first guiding portion 41 toward the second guiding portion 42.

ワーク交換装置２０の付近において、第三案内部２３が冷却液を受け部５０に案内する。第三案内部２３はアーム２２の後側領域において、冷却液を収集する。第三案内部２３が冷却液を収集する領域に受け部５０を配置する必要はない。実施の形態においては、第三案内部２３はアーム２２の後側に配置してあるので、受け部５０を後方に延ばす必要がなく、受け部５０の面積を小さくし、小型化できる。   In the vicinity of the workpiece changer 20, the third guiding portion 23 guides the coolant to the receiving portion 50. The third guiding portion 23 collects the coolant in the rear area of the arm 22. It is not necessary to arrange the receiving portion 50 in the area where the third guide portion 23 collects the coolant. In the embodiment, since the third guide portion 23 is disposed on the rear side of the arm 22, there is no need to extend the receiving portion 50 backward, and the area of the receiving portion 50 can be reduced and the size can be reduced.
