て該動作に非干渉となるように構成している。Conventionally, as shown in FIGS. 5 and 6, a machine tool M is provided with a cover 1 that covers the periphery of the machining part in order to prevent the cutting fluid used during machining from scattering.
When this type of machine tool is equipped with a pallet changer 10 that can quickly exchange two pallets P and P on which workpieces W are placed as shown in the figure, the pallet rotating part 10a is In order not to interfere with the lift stroke for vertical movement and the movement of horizontal rotation for changing to another pallet, the area corresponding to the movement range is cut out or otherwise opened, and a door is provided to cover the open area to prevent the machining area from being damaged. is configured to close. In the figure, an opening 1a is formed at a location corresponding to the processed portion of the cover 1, and a door 11 that closes the opening 1a is molded and placed upright on the pallet changer. When replacing the pallet, the layer 11 is provided to operate together with the pallet rotating part 10a, and the door 11
A gap is created between the opening 1a and the opening 1a so that the opening 1a can move up and down and rotate. For this reason, in cases where the door portion is disposed on the pallet changer side, there is currently a gap portion of the cover related to the rotation of the door even during processing. Also, although not shown in the figure, some of the doors of this type of cutting fluid scattering prevention cover are rotatable, sliding, or hinged, and are installed at appropriate locations on the cover, but none of them are suitable for pallets. The operating range related to replacement is kept open so that there is no interference with the operation.

There is a problem in that the cutting fluid scatters outward and a sufficient prevention effect cannot be obtained, or there is a problem in that opening and closing the door takes time and work efficiency is reduced. The present invention was made under the above circumstances,
The purpose of this is to configure the door to change its appearance according to the operation of the pallet changer, which will seal the processing area during machining to prevent cutting fluid from scattering outside, and cover the door when changing pallets. An object of the present invention is to provide a cutting fluid scattering prevention cover that does not require direct operation.

In addition, when the revolving part is raised to replace the pallet, the rotating cover also rises, and the overlapping margin of the oblique side of the rotating cover with the oblique side of the opening is reduced according to this upward lift stroke. This gradually decreases, creating a gap between the oblique side of the opening of the fixed cover and the oblique side of the rotating cover. Therefore, due to the gap, the oblique side of the opening does not interfere with the horizontal rotation movement of the pallet rotating section, allowing rotation of the pallet, and the other pallet is placed on the processing section side. When the pallet is replaced and the pallet rotating section is lowered,
Along with the lift stroke, the gap between the oblique side of the rotary cover and the oblique side of the opening narrows and they gradually overlap, and the overlapping margin widens to seal the processing section.

するものである。Embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 4. In this embodiment, the same reference numerals are used for the parts having the same structure as those of the conventional structure shown in FIGS. 5 and 6, and the explanation thereof will be omitted. Figures 1, 2, and 2 show an embodiment of the present invention, which consists of a fixed cover 1 disposed on the machine body side and a rotating cover 2 disposed on the pallet changer 10 side, which partitions two pallets. An inverted trapezoidal opening 1a is formed at a position corresponding to the machining section on the front surface of the fixed cover 1 extending to the pallet changer side so as to enable horizontal rotation of the pallet without contact. The rotating cover 2 is formed into an inverted trapezoid shape with dimensions that create a gap with the opening hypotenuses tb, tb as the lift stroke rises, and an overlap margin with the opening hypotenuses as it descends, and the pallet is located in the middle of the two pallets. It is constructed by standing up on the rotating section 10a. That is, in the rotating cover 2, the length of the lower base of the inverted trapezoidal shape with respect to the fixed cover 1 is slightly longer than that of the opening 1a, and the height thereof is appropriately larger than that of the opening. If the rotating cover 2 is provided with a short dimension and the lower bottom sides of the rotating cover and the opening are on the same plane, a portion D1D that will overlap with the fixed cover 1 will be created on both oblique sides 2a12a of the rotating cover 2. It is molded into. As a result, as shown in FIG. 3, the rotating cover 2 erected in the pallet rotating section 10a of the pallet changer is moved to both oblique sides 2a1 at the lowest lift stroke limit of the pallet rotating section.
The maximum width of the overlap margin D occurs at 2a, and as shown in Figure 4, the width of the overlap margin gradually decreases during the rising process of the lift stroke, and the width connecting both oblique sides of the opening and the width of the lower base. When passing through an intermediate point where the two coincide with each other, the overlapping margin is eliminated, and as the lift stroke approaches the upper limit, a gap d1d gradually forms between the opening and the oblique side. Therefore, when replacing the pallet, the pallet rotating portion rises and both oblique sides of the opening 1a and both oblique sides 2a of the rotating cover 2 are removed.
12a, when gaps d and d are created between the rotary cover 2 and
When the pallet performs a horizontal rotation operation, it becomes rotatable without interfering with the fixed cover 1, and after being replaced by the other pallet due to the horizontal rotation, the pallet moves both sides of the rotating cover 2 again during the descending lift stroke. An overlap margin D1D is created on the oblique side portion with the opening portion 1a, and the processed portion is sealed. Therefore, since the fixed cover 1 and the rotating cover 2 overlap during machining, there is no gap for cutting fluid to scatter, and the machining area can be kept in a sealed state. The aspect of the rotating cover 2 relative to the opening 1a of the fixed cover 1 changes according to the movement of the opening 1a of the fixed cover 1, thereby eliminating the need for work related to opening and closing the door portion. Reference numeral 3 designates a rubber cover provided on the upper bottom side of the opening of the fixed cover, and when the rotating cover is at the lowest limit of the lift stroke of the pallet rotating section, its free end overlaps with the lower bottom side of the rotating cover, and the pallet The free end is arranged like a curtain so that it can flexibly respond to the rise and rotation of the rotating part, and maintains a sealed state during processing. Reference numeral 4 designates monitoring windows provided at appropriate locations on the fixed cover and the rotating cover to monitor the machining state, and are constructed by cutting out portions necessary for monitoring and disposing transparent members.

を奏するものである。As explained above, according to the present invention, the fixed cover is provided on the machine tool side and the rotating cover is provided on the pallet changer side, and the fixed cover has an inverted trapezoidal opening on the side corresponding to the processing section. On the other hand, the rotating cover is formed into an inverted trapezoid shape with dimensions that create a gap with the oblique side of the opening part when the lift stroke goes up, and overlap with the oblique side of the opening part when descending. By installing the pallet rotating part vertically, the aspect of the rotating cover relative to the fixed cover changes according to the operation of the pallet changer, and during machining, the machining area is sealed to prevent cutting fluid etc. from scattering to the outside. This has the excellent effect of preventing the need for direct operation of the cover when replacing the pallet.
