成するものである。Hereinafter, embodiments of the present invention will be described in detail with reference to FIG. 1 to FIG. In the present embodiment, the same reference numerals are used for the portions having the same configuration as those of the conventional structure shown in FIGS. 5 and 6, and the description is omitted. FIGS. 1 and 2 show one embodiment of the present invention, which comprises a fixed cover 1 provided on the machine main body side and a rotary cover 2 provided on the pallet changer 10 side so as to partition two pallets. An inverted trapezoidal opening 1a is formed in the front surface of the fixed cover 1 extending to the pallet changer side at a position corresponding to the processing portion so that the pallet can be rotated horizontally without contact. The cover 2 is formed into an inverted trapezoidal shape in which the clearance between the oblique sides 1b and 1b is generated by raising the lift stroke and the overlap with the oblique side of the opening is generated when the cover 2 is lowered. It is configured to stand upright on the part 10a. That is, in the rotating cover 2, the fixed cover 1
On the other hand, the length of the lower base of the inverted trapezoid is slightly longer than that of the opening 1a, and the height thereof is appropriately shorter than that of the opening 1a. Are formed such that portions D, D which overlap the fixed cover 1 are formed at both oblique sides 2a, 2a of the rotating cover 2 when the lower bottom sides of the rotating cover 2 are on the same plane. As a result, as shown in FIG. 3, the rotary cover 2 erected on the pallet swivel portion 10a of the pallet changer overlaps the oblique sides 2a, 2a with a maximum width D, D at the lowest lift stroke of the pad swivel portion. As shown in FIG. 4, the width of the overlapping margin gradually decreases in the process of raising the lift stroke, and the overlapping margin passes when the width connecting the two oblique sides of the opening and the width of the lower base coincide with each other. Are eliminated, and gaps d and d are gradually generated between the upper end of the lift stroke and the oblique side of the opening. Therefore, when the pallet is replaced, the pallet swivel section rises, and both hypotenuses of the opening 1a and both hypotenuses 2a of the rotating cover 2 are moved.
2a, the rotating cover 2 and the pallet can rotate without interfering with the fixed cover 1 when performing the horizontal rotation operation, and the other pallet can be rotated by the horizontal rotation. With the descending lift stroke after the replacement, the overlapping margins D and D with the opening 1a are generated again on both oblique sides of the rotating cover 2, and the processed part is closed. Therefore, at the time of processing, the fixed cover 1 and the rotating cover 2
And the machining portion can be sealed without gaps where cutting fluid or the like is scattered. However, when the pallet is replaced, the opening of the fixed cover 1 is changed according to the operation of the pallet turning portion 10a. The mode of the rotating cover 2 with respect to 1a changes, and the work related to opening and closing the door portion is not required. Reference numeral 3 denotes a rubber cover provided on the upper bottom side of the opening of the fixed cover. When the rotary cover is at the lower limit of the lift stroke of the pallet swivel section, its free end overlaps the upper bottom side of the rotary cover, The free end is arranged in a goodwill shape so that the free end responds flexibly when the revolving part is raised and rotated, and maintains a sealed state during processing. Reference numeral 4 denotes a monitoring window provided at an appropriate position of the fixed cover and the rotating cover for monitoring a processing state, which is formed by cutting out a portion necessary for monitoring and disposing a transparent member.
