In more detail, the object of the present invention is to provide a non-lubricating gap between a transmission surface and a solid lubricating seal portion due to assembly tolerances and wear. A solid lubrication seal automatic position correcting device that achieves precise automatic correction by lubricating the position correcting force of the seal portion itself.

Generally, the LM guide includes: a guide rail having a transmission surface; a guide block, which is transported along the guide rail; and a plurality of transmission bodies arranged to circulate inside the guide block to perform a rolling motion along the transmission surface, in order to prevent Wear occurs due to friction with the transmission body, and in order to smoothly transfer, it is necessary to continuously supply lubricating oil to the transmission surface.

However, since the first lubricating oil coating body, the second lubricating oil coating body, and the plate are required to be layered, the structure is complicated, especially when the first lubricating oil coating body and the second lubricating oil coating body are not in contact with each other. In the case of wear or tear on the same axis of the rail rail, the disadvantage of direct connection is caused by poor lubrication.

Further, in the Korean Patent Publication No. 10-0318100, the following device structure is disclosed, that is, as a sliding member attached to a track shaft by a transmission body, and by the relative relationship between the sliding member and the track shaft A lubricating oil supply device for applying lubricating oil to a track shaft, comprising: a casing fixed to the sliding member; and a plurality of coating sheets protruding from a plurality of positions of the casing in contact with the track shaft to orbit a shaft coating lubricating oil; and a lubricating oil accommodating chamber provided in the outer casing for supplying lubricating oil to the coating sheet, wherein the plurality of coating sheets are divided into groups, and each group is formed with a lubricating oil accommodating chamber, The lubricating oil is uniformly applied to each of the application sheets regardless of the state in which the rail shaft is attached to the fixing portion of the base or the like.

However, in the above-described prior art, as the application sheet (lubricating oil coating body) is provided in a state of being fixed to the outer casing (plate), the coating sheet (lubricating oil coating) is applied when the outer casing (plate) assembly tolerance occurs. The body is in a tilted state on the track rail surface, resulting in the formation of a non-lubricated non-lubricating slit, thereby causing a problem that the lubricating oil coating is deteriorated.

Moreover, according to the characteristics of the lubricating oil coating sheet which continuously rubs against the surface of the rail rail, only a specific portion which is in contact with the surface of the rail rail is easily worn and deformed, and is formed to be spaced apart from the rail rail surface in accordance with the degree of wear. The non-lubricating gap causes the lubrication to deteriorate, thereby causing the problem of prematurely changing the lubricant application body irrespective of the remaining amount of the lubricating oil.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

The present invention relates to a solid lubrication seal automatic position correcting device. The automatic position correcting device as the main constituent solid lubricating seal portion includes the solid lubricating seal portion 10, the docking chamber 20, the correcting space portion 30, the abutting portion 40, and the elastic body 50, so that the transmission surface and the solid lubrication are caused by assembly tolerances and wear. The non-lubricating gap between the seals achieves precise automatic correction by means of the positional correcting force of the solid lubricating seal itself.

In the present invention, the solid lubricating seal portion 10 is provided. The solid lubrication seal 10 is separately formed in such a manner as to lubricate the guide block 8 and the transmission face 2 separately, and the guide block 8 is transferred along the transmission faces 2 on both sides of the guide rail 1 so that the transmission body 6 corresponds to the transmission face 2. The position of the loop is set in a way. The solid lubricating seal portion 10 is made of a component containing a plastic resin and a lubricating oil, and is a plastic resin composition in which lubricating oil continuously flows out. Since the physical properties are soft, the shape of the guide rail is considered in advance to form a lubrication at a position corresponding to the transmission surface. Tolerance processing is performed in a face-to-face manner.

However, in the case where the position is deviated when the solid lubricating seal portion 10 is assembled or wear occurs during use, the corresponding portion is in the lifted state, resulting in a non-lubricating surface, causing poor lubrication, and thus the present invention considers the solid lubricating seal portion. 10 has soft physical properties, and the solid lubricating seals 10 are separately formed by separately lubricating the two side transmission faces 2, and are respectively disposed in the docking chamber 20, thereby performing automatic position by means of the butt joint 40 being coupled in the correct position. Correction.

At this time, the solid lubricating seal portion 10 is separately formed, and the elastic supporting force acts to lubricate each of the transmission faces 2 separately, and the elastic supporting force of the elastic body is symmetrical with respect to the center of the lubricating surface and the transmission surface. Evenly, the contact force between the respective lubricating surfaces 42 and the transmission surface 2 is uniformly acted to prevent the partial wear of the lubricating surface 42.

Further, the docking chamber 20 of the present invention is provided in the guide block 8, and the lubrication port 22 is formed to accommodate the solid lubricating seal portion 10 in the independent space and to accommodate the transmission surface 2 of the guide rail 1. The docking chamber 20 is formed such that each solid lubricating seal portion 10 is housed in a separate space. At this time, the docking chamber 20 is formed in the form of an end plate 8a of the LM guide, as shown in FIG. In a symmetrical manner, a lubrication port 22 is formed on one side of the docking chamber 20 corresponding to the transmission face 2.

At this time, the lubrication port 22 is opened in a manner that the transmission surface 2 is housed inside the docking chamber 20 and is lubricated by the solid lubricating seal portion 10, wherein the lubrication port 22 is formed on the side wall of the docking chamber 20 in such a manner that the transmission surface 2 is partially housed. A part of the section causes the solid lubricating seal portion 10 housed inside the docking chamber 20 to be caught on the side wall adjacent to the lubrication port 22, thereby preventing detachment from the outside.

Further, the correction space portion 30 of the present invention is formed such that the solid lubrication sealing portion 10 moves inside the abutting chamber 20 along a circumference orthogonal to the longitudinal direction of the guide rail 1. The correction space portion 30 is a space formed between the inner wall surface of the docking chamber 20 and the outer circumferential surface of the solid lubrication seal portion 10, and the correction space portion 30 allows the solid lubrication seal portion 10 to be along the longitudinal direction of the guide rail 1 inside the docking chamber 20. The orthogonal movement moves around, but the movement is restricted along the length of the guide rail 1.

Therefore, as the solid lubricating seal portion 10 can be moved along the circumference orthogonal to the longitudinal direction of the guide rail 1 by the correction space portion 30, even if the assembly tolerance is generated when the docking chamber 20 is placed on the guide block 8, it is solid. The self-movement of the lubrication seal 10 is corrected to correct the error value, and even if the lubrication surface 42 is worn during use, the non-lubrication gap is automatically compensated by the movement of the solid lubrication seal 10, and the solid lubrication seal is also caused. The up-and-down movement of 10 is suitable for the deformed product group in which the transmission surface of the guide rail 1 is designed in a different height, and thus has versatility.

Further, the abutting portion 40 of the present invention is constituted by a pair of lubricating surfaces 42, and the width thereof is narrower toward the inner side, so that the transmission surface 2 that is directed to the lubrication port 22 is inserted. The abutting portion 40 is for guiding the solid lubricating seal portion 10 to accurately reach the lubrication position by meshing with the transmission surface 2 of the guide rail 1, and has a pair of lubricating faces 42 due to a structure having a narrower outer width and a narrower width toward the inner side. The sliding movement along the pair of transmission faces 2 is directed to the center and accurately engaged, so that the non-lubrication gap due to assembly tolerances and wear is automatically corrected.

At this time, a pair of circular arc-shaped lubricating faces 42 are disposed in a symmetrical manner on the abutting portion 40 to form a circular arc-shaped line, wherein the circular arc-shaped line of the lubricating surface 42 and the circular-shaped line of the transmission surface 2 It is formed by a circumference of the same diameter. When the lubrication surface 42 of any one side is worn due to friction, the lubrication surface 42 of the other side rotates on the same axis as the transmission surface 2 (for example, the circular arc-shaped circumferential center of the lubrication surface 42 and the transmission surface 2), thereby The gap due to wear is closely corrected.

Further, the solid lubricating seal portion 10 of the present invention is elastically supported by the elastic body 50 and guided by the butting portion 40, so that the position correcting force of the pair of lubricating faces 42 in contact with the respective transmission faces 2 functions. The elastic body 50 is formed of a coil spring, and is disposed between the opposite side surface of the solid lubricating seal portion 10 facing the abutting portion 40 and the side wall of the butt chamber 20, and pressurizes the solid lubricating seal portion 10 toward the side of the transmission surface 2 of the guide rail 1.

Therefore, the solid lubricating seal portion 10 elastically supported by the elastic body 50 is guided by the abutting portion 40 and meshed along the transmission surface 2 of the guide rail 1 in the same axis (for example, the center line between the pair of transmission faces 2 and one The center line between the lubricating faces 42 is on the same line so as to continuously generate a position correcting force, which has the advantage of correcting the position of the solid lubricating seal 10 in accordance with the tolerance magnitude of the wear of the lubricating face 42 during use.

At this time, on both sides of the guide rail 1, a circular arc-shaped transmission surface 2 symmetrical with respect to the center of the male corner surface 3 is disposed, and the solid lubricating seal portion 10 is lubricated to a pair of circular arc shapes corresponding to the transmission surface 2. The face 42 is disposed so as to be symmetrical with respect to the female face 43 and a non-contact slit 60 for compensating for the amount of wear is formed between the male face 3 and the female face 43. That is, the solid lubricating seal portion 10 guided by the abutting portion 40 and combined with the transmission surface 2 maintains only the lubricating surface 42 of the guide surface 1 and the lubricating surface 42 of the solid lubricating seal portion 10 by the non-contact slit 60. The state of contact thus concentrates the elastic supporting force of the elastic body 50 to the side of the transmission face 2, improving the airtightness with the lubricating face 42, in particular, even if the lubricating face 42 is worn, due to the contactless slit 60 The movement space based on the position correction of the solid lubrication seal portion 10 is secured, so that the tolerance gap due to wear is naturally corrected.

Further, the male angle surface 3 and the female angle surface 43 are connected to the transmission surface 2 and the lubrication surface 42 at an obtuse angle. Therefore, as the protruding end portion of the male corner surface 3 enters toward the inside of the abutting portion 40, the gap formed between the lubricating surface 42 and the lubricating surface 42 is gradually narrowed, thereby not only being more tightly coupled on the same straight line, but also preventing the use process. A non-lubricating gap is generated due to the movement of the solid lubricating seal portion 10.

Further, the elastic body 50 is provided at one position on the center line between the pair of lubricating faces 42, or at two positions symmetrical with respect to the center line between the pair of lubricating faces 42, the end of the elastic body 50 The portion is fixed by being housed in the side groove 11 of the solid lubricating seal portion 10, and the other end portion of the elastic body 50 is provided to be movable along the inner wall of the butt chamber 20.

2 shows a state in which the elastic body 50 is placed at one position. At this time, since the solid lubricating seal portion 10 is elastically supported by one elastic body 50, the resistance is reduced by the movement of up, down, left, and right, and thus the movement is based on the position correction. Advantages of the nature, FIG. 3 shows a state in which the two elastic bodies 50 are arranged apart from each other, and the elastic supporting force acts stably at two positions, thereby preventing swimming and swaying during operation, and in a pair of lubrication Face 42 produces the advantage of a uniform position correction force.

Further, one end of the elastic body 50 is housed in the side groove 11, and the other end of the elastic body 50 is provided to be movable along the inner wall of the docking chamber 20, and is guided by the butting portion 40 to be positioned at the solid lubricating seal portion 10. The elastic body 50 is moved together during the correction. Therefore, the elastic supporting force of the elastic body 50 acts on the same straight line as the direction in which the butting portion 40 enters, so that the elastic supporting force applied to the pair of lubricating faces 42 and the driving face 2 is maintained uniform.

On the other hand, preferably, the elastic body 50 uses a coil spring having a sum of elastic forces of 0.5 to 6 N so that the position correcting force of the size in which the lubricating surface 42 is in contact with the transmission surface 2 and is not spaced apart functions. At this time, if the sum of the elastic forces is less than 0.5 N, a stable contact force cannot be obtained, and if the sum of the elastic forces is more than 6 N, the lubricating surface is likely to be worn due to excessive contact force.
