Description of the Related Art When chips or the like are present on a guide surface in a machine tool, a carriage or the like moving on the guide surface may bite the chips and cause damage to the guide surface and the back surface of the carriage or the like. become. Therefore, in the past, a guide surface wiper was attached to a guide surface entrance / exit portion of a carriage or the like to prevent bites or the like existing on the guide surface from being caught by the guide surface wiper. However, in order to prevent chips and the like from falling on the guide surface, a cover for completely cutting off the cutting area where the chips are generated and the guide surface has come to be used. When the machine tool is small, this cover may be one sheet. However, when the machine tool becomes large, it is necessary to divide the cover into a plurality of sheets, overlap the covers, and slide them in a nested manner.
Therefore, it has been practiced to close the gap so that chips, dirt, and cutting water do not enter the gap and fall onto the guide surface.

It is fixed parallel to the axis. Headstock 1 of carriage 104
A second cover 110 having a cross section similar to that of the first cover 109 is attached to the end surface on the 01 side, and the left end of the second cover 110 is inserted into a state of being superimposed on the back side of the first cover 109.

As shown in FIG. 5, a wiper 112 made of a band-shaped rubber material is provided on the right edge of the first cover 109 as a presser 113.
And attached with a small screw 114. Then, a strip-shaped scraper 115 made of a thin spring steel plate is adhered to the tip of the wiper 112 made of a band-shaped rubber material and pressed against the upper surface of the second cover 110.

Since the spring constant of 5a is low, there is a problem that once chips or the like enter, they may be easily turned up.
Further, since the thin spring steel plate is inflexible, if a strip-shaped scraper 115 made of a thin spring steel plate is turned up at one place, a gap is formed between the second cover 110 and a wide area, and the function as a wiper cannot be achieved. Had. Further, since the thin spring steel plate is not flexible, there is a problem that the strip-shaped scraper 115 made of the thin spring steel plate is broken and broken by repeating the biting phenomenon of the chips. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and aims at using a scraper made of a strip-shaped thin-walled spring steel plate and losing the wiper function even if biting of cutting chips occurs. Is not to try to provide a wiper.

ある。In order to achieve the above object, at least two wipers according to the present invention are provided such that at least two wipers are in pressure contact with one of the relatively movable covers and the other with the other. A wiper with a lip for closing the gap to prevent intrusion of cuttings and cutting fluid, wherein a scraper made of a band-shaped thin-walled spring steel plate is provided along a bendable tip of a wiper body made of a rubber material along the tip. The scraper is attached and integrated, and the tip of the scraper is corrugated.

Occurs. That is, the peak of the waveform has a small pressing force on the lower cover, and the trough of the waveform has a high pressing force on the lower cover. In a strip-shaped scraper made of thin spring steel plate, the tip of the lip is made to have a continuously changing waveform, so that chips scattered on the upper surface of the lower cover are separated by the peak of the waveform and the valley of the waveform is formed. Collected in the part. The chips are prevented from penetrating into the gap between the two covers due to the chip removal effect by the large pressing force at the valley portion of the waveform. Also, if the chips are strip-shaped at the peak of the corrugation and bite into the lip tip edge of a thin spring steel sheet scraper, the tip edge of the lip is turned up at only one peak at the biting point and the wiper No effect. However, it does not turn up to adjacent valleys and other peaks, and functions as a normal wiper except at the biting portion of the chips.

に落下する。[Operation] It is now assumed that chips, cutting water and the like are scattered on the upper surface of the one-side cover 2 and the lower cover 2 moves to the upper left in FIG. When the chips and cutting water come into contact with the strip-shaped scraper 6 made of a thin spring steel plate, the lip 6
a It is separated by the peak portion 6b at the tip edge and is collected in the valley portion 6c. The valley portion 6c has a large pressing force against the upper surface of the lower cover 2, and the chips collected by this large pressing force are such that chips enter between the valley portion 6c and the upper surface of the lower cover 2. Without climbing phenomenon, the robot rides on the scraper 6 and falls from the scraper 6 to a not-shown chip collecting device provided at the lower part of the machine.

として作用する。Since the tip of the lip 6a, which is in contact with the upper surface of the lower cover 2 at the end of the scraper 6 made of a strip of thin spring steel plate, is formed in a continuously changing waveform, the peak portion 6b of the waveform is formed in the lower cover. 2 has a small pressure contact force on the upper surface. Therefore, the chips on the lower cover 2 are removed from the ridge 6
In the case of being separated by b, swarf may accidentally enter between the mountain portion 6b and the upper surface of the lower cover 2 to cause a biting phenomenon. At this time, the scraper 6 turns up only one peak 6b at the tip edge of the lip 6a in which the chip is bitten. The valley portions 6c on both sides are not turned up because the pressing force against the upper surface of the lower cover 2 is large.
Of course, there is no turning over other mountain parts. Therefore, the portion other than the mountain portion 6b into which the cuttings are bitten acts as a normal wiper.

According to the wiper of the first aspect, since the edge of the lip in contact with the lower cover of the scraper made of a strip-shaped thin spring steel plate has a continuously changing waveform, the magnitude of the pressure contact force with the lower cover is increased. That is, the ridge of the waveform has a small pressing force on the lower cover, and the valley of the waveform has a large pressing force on the lower cover.
By making the lip tip edge continuously change in waveform in the strip-shaped thin spring steel plate scraper, the chips scattered on the upper surface of the lower cover are separated by the peak of the waveform and the valley of the waveform is formed. Collected in parts. The chips are prevented from penetrating into the gap between the two covers due to the chip removal effect by the large pressing force at the valley portion of the waveform. However, when the chips are bitten at the peak of the waveform, only one peak of the biting portion is turned up and the wiper effect is lost. At this time, the adjacent valley portion and other ridge portions are not turned up, and the portions other than the biting portion of the chips function as normal wipers.
In addition, until the bitten chips are removed, the chips are present at the biting portion, so that the chips rarely invade sequentially from here, and can function as a wiper. Further, since the pressure contact force is small at the ridge portion, the ridge portion and the upper surface of the lower cover are not deformed or damaged by the bitten chips. Further, since the pressure contact force is small at the peak portion, it is easy to remove the bitten chips.
