A pallet-mounted cover device having a surface swiveling pallet is disclosed in JP-A-62-79943 and JP-A-1-3010.
What is seen in No. 39 etc. has been proposed as a publicly known means.
The feature of these pallet-mounted cover devices is that the machining area facing the spindle and the work replacement area facing the operator are separated (sectioned) so that chips and coolant generated in the machining area do not scatter in the work replacement area. In addition to the above-mentioned guarding, the upper side of the cover is inclined toward the workpiece exchange area side to widen the machining area to expand the movement range of the spindle. Furthermore,
The cover is turned integrally with the pallet by using the turning movement of the two-sided turning pallet as a driving source to reverse and reverse the pallet.

る。In the above pallet-mounted cover device, when a cover body that is still in a tilted posture is turned upside down and turned 180 °, the cover body in a tilted posture turns to a vertical posture by turning 90 °, and the remaining 90 °, that is, Since it turns to the opposite side by turning 180 degrees, the upper and lower edges of the cover are hinged. For this reason, if the pallet is rotated 180 degrees at a high speed, a large eccentric stress is applied to the cover, which damages the hinge and the cover at an early stage, and also causes a problem that the work on the pallet and the cover body in the inclined posture interfere with each other. There is a point.

押しながら連れ回し反転動作を行う。The detailed operation will be described below with reference to FIGS. When the two-sided pallet P is clamped down to the level L1, the machining area K of the spindle S having a large space and the side of the operator who is not affected by the coolant or cutting chips are provided by the swivel cover body 21 that isolates the left and right sides from the center of the two-sided pallet. Is separated from the work exchange area W. Therefore, the work efficiency in each area can be improved. Further, prior to the reversal of the two-sided pallet P, the pallet is lifted up to the level L2 by several mm and the clamp is removed. By this operation, the two support pieces 22, 2 that face the lower surface of the lower edge 21A of the swivel cover body 21 and the loose side.
3 also enters the lower edge 21A and rises to the position indicated by the chain double-dashed line. At all times, a slight space X is formed between the swivel cover body 21 and the upper fixed cover body 7, and the support pieces 22, 23, 24, 25 are rotated while pushing the swivel cover body 21 in synchronization with the reversing swiveling of the pallet. Reverse operation is performed.

First, in FIG. 5A, the swivel cover body 21 is pushed and rotated by the support piece 23 on the pallet that swivels clockwise. The section from FIG. 5B to 135 ° in FIG. 5C is pushed around by the support piece 23. After that, the support piece 25 starts to be pushed around, and at the end of 180 ° inversion, the pair of support pieces 25, 2
It is stopped by 4. After that, the pallet clamp ends by performing the sinking operation of the pallet P from the two-dot chain line position to the level L1 at the solid line position. Even in this operation, the space is kept at the minimum X, and the lower edge 21A of the swivel cover body 21 is also held by the support pieces 24 and 25 facing loosely, and the minimum gap Y is formed between the space and the pallet surface. It remains close and the cover is waterproof.
