EMBODIMENT OF THE INVENTION 1. The present invention relates to a track rail and a moving block which are formed by a combination of a plurality of balls, so that the object to be mounted fixed to the moving block can be mounted. A rolling guide device that reciprocates freely along the 'track rails, in particular, an infinite loop path with balls on the moving block I, which allows the balls to be infinitely looped while the moving blocks are continuous along the track rails. The moving scroll guide is mounted. [Prior Art] Most of the linear guides for the working platform of the working machine or the various conveying devices are rolling guides that continuously move along the rail rails using a moving block on which a movable body such as a platform is mounted. In the rolling guide device, the moving block is coupled to the rail rail by a plurality of balls, and the ball is loaded between the moving block and the rail rail by the load. The upper moving body can move lightly along the track rail with little resistance. Further, the moving block is an infinite loop having balls, and the moving block can be continuously moved along the track without interruption through the circulation of the balls in the infinite loop. The track rail is a groove groove formed with a ball along a long direction, and the other moving block is formed with a load groove facing the ball groove of the track rail, and the track rail side is The ball rolling groove and the load grooving on the moving block side form a load rolling passage of the ball. In other words, the balls are in contact with the ball groove on the rail rail side and the load groove on the moving block side, and are configured such that the side 8 (2) 1375758 is used for the load to roll between the load sides. Further, the moving block is formed with a no-load rolling passage parallel to the load rolling groove, and the two ends of the unloaded rolling passage are connected through a pair of direction changing passages formed in an arc shape. Connected to the above-mentioned no-load rolling channel. The end of the ball at the load rolling passage is the unloading weight, which is separated from the ball groove of the track rail and enters the above-mentioned direction switching path, from which the switching path rolls toward the no-load rolling path. In addition, the balls rolling in the no-load rolling passage are returned to the ball groove of the track rail through the opposite side direction, and are again rolled in the rolling path while being loaded with the load. As described above, the moving block is an infinite circulation path having balls continuously formed by a load rolling passage, a direction switching passage, a no-load rolling passage, and a direction changing passage, and the load of the load is repeated on the infinite loop road by the ball side circulation. The state and no-load state allow the moving block to move continuously along the track rail without stroke. The moving block is formed by a block body formed of hardened steel, and a pair of synthetic resin end caps fixed to the front and rear end faces of the block body, Φ. The load rolling passage is formed by grinding on the block body, and In one aspect, the unloaded rolling passage is formed in the block body by a through hole having an inner diameter larger than a diameter of the ball so as to be parallel to the load rolling passage, thereby forming a tunnel-shaped unloaded rolling passage. Further, the direction change track is formed on the end cover, and the end cover is fixed to the front and rear end faces of the block body, so that the end portion of the load rolling passage and the end portion of the no-load rolling passage are connected in the direction change path, This is an infinite circulation path of the ball (Japanese Patent Laid-Open No. Hei 10-009264, Japanese Unexamined Publication No. Hei-4-53459). [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei 4-53459. The above-described structure of the infinite loop on the rolling guide device requires a large number of machining operations or parts for the moving block to have a no-load rolling passage or a direction changing passage, and it takes time and effort to manufacture and assemble the moving block. In fact, there is a problem that the production cost becomes high. Further, since the balls roll on the load grooves of the block body while being loaded with the load, the surface hardness of the load grooves needs to be increased. Therefore, it is necessary to apply a quench hardening treatment to the load groove forming portions of the block body. On the other hand, the whole body of the block is subjected to quench hardening treatment, which may cause difficulty in processing the unloaded rolling passage or the processing of the plug for fixing the movable body. Therefore, it is conventionally practiced to perform carburization and hardening only on a portion such as a load rolling surface which requires quench hardening treatment, but it takes a lot of work in terms of processing, and after all, it causes an increase in production cost. [Means for Solving the Problem] The present invention has been made in view of the above problems, and an object of the invention is to provide an infinite circulation path in which a moving block can be easily provided with balls, and the number of parts or the number of processing units can be reduced. A rolling 'guide device that can be easily and inexpensively manufactured. In order to achieve the above object, the rolling guide device of the present invention comprises: a track rail formed with a ball groove along a long direction; and a plurality of balls arranged in a group -6 - 8 (4) 1375758 coupled to the track The rail has the infinite loop of the above-mentioned balls at the same time. 'The movable block that can move freely along the track rails. Further, the moving block ′ is formed to include a block body to be fixed by the mounted body, and a ball circulation plate that is attached to the block body at a position where the ball rolling surfaces of the track rails face each other to form the infinite loop path. . At least the ball circulation plate is formed with a load straight groove that faces the groove of the track rail; and a load-free straight groove that is parallel to the load straight groove and opens toward the track rail. Then, the ball is rolled between the load straight groove and the groove of the track rail in the load straight groove of the ball circulation plate, and the side is guided in the no-load straight groove. The side between the load straight groove and the track rail rolls in an unloaded state. In the case of the above-described rolling guide device of the present invention, the block body for constituting the moving block may be formed by a mounting surface of the object to be transported such as a work platform and a mounting position of the ball circulation plate. The no-load rolling channel for circulation is not necessarily formed on the block body, so the processing of the above-mentioned block body can be easily performed. Further, the ball is a straight line groove formed by rolling on the ball circulation plate and does not roll on the block body. Therefore, the block body is not subjected to quench hardening treatment, and can be formed using an inexpensive material such as mild steel. On the other hand, the ball circulation plate to be mounted on the block body is formed with a load straight groove which faces the groove of the track rail; and a load-free straight groove which is parallel to the load straight groove, but these The grooves are formed open to the track rails. Therefore, it can be easily formed by machining such as cutting before the ball circulation plate is coupled to the block body, and (5) 1375758, and it is not necessary to use a special working machine. The commonly used work machine will be able to process. In this way, the ball circulation plate can be formed at a low cost, and the moving block can be inexpensive and easily produced as a whole. In addition, a pair of direction changing grooves between the load straight groove and the unloaded straight groove can be formed on the ball circulation plate, and the load straight groove, the unloaded straight groove, and the pair of direction conversion grooves are continuous. When the formed ball circulation groove is formed in the ball circulation plate, the ball circulation plate alone can form an infinite circulation path of the balls, so that the moving block can be produced more inexpensively and easily. [Embodiment] BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a rolling guide device of the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 and Fig. 2 are views showing a first embodiment of a rolling guide device formed by applying the present invention. The rolling guide device 1 of the first embodiment is a rail rail 10 to be fixed to a mounted portion such as a machine tool or a column, and a moving block that is coupled and coupled to the rail rail 10 via a plurality of balls. The 20 configuration is configured such that the moving block 20 can freely reciprocate on the track rail 10. The track rail 10 has a substantially rectangular cross section perpendicular to the longitudinal direction. The bottom surface is a fixing surface to be fixed to the mounted portion. In addition, the mounting hole 12 is provided with a fixing bolt at a predetermined interval, and the fixing bolt inserted through the mounting hole is fastened to the skirt portion 23 of the mounted portion, -8 - 8 (7) 1375758. A mounting groove 26 is formed. As shown in Figs. 3 and 4, the ball circulation ring 30 is formed with a ball circulation groove 31 in which a plurality of balls 2 are accommodated at a position facing the side surface of the track rail 10. The ball circulation groove 31 is a load straight groove 32 that faces the ball groove 13 of the track rail 1〇, and a load-free straight groove 33 that faces the ball holding groove 14 of the track rail 10; The end portions of the load straight groove 32 and the unloaded straight groove 33 form a pair of direction changing grooves 34 and 34 which are connected to each other. Between the ball rolling groove 13 of the track rail 1〇 and the load straight groove 32 of the ball circulation plate 30, the ball circulation plate 30 is moved from the track rail 10 side toward the moving block 20 by the load carrying the ball 2 The inside of the mounting groove 26 is pressed, whereby the ball circulation plate 30 is held in the mounting groove 26 at the skirt portion 23. Further, as shown in Fig. 1, the stopper members 40 and 40 are fixed to the front and rear end faces of the moving block 20 in the moving direction, and the movement of the ball circulation plate 30 in the longitudinal direction by these stopper members 40 and 40 becomes The card is locked. The stopper member is provided with a rubber end seal 41 which is a gap formed to seal the rail rail and the moving block. That is, the ball circulation groove 31 is fitted only to the mounting groove 26 of the moving block 20, and when the moving block 20 is removed from the track rail 10, the ball circulation plate 30 can be easily detached from the moving block 20. Further, the 'ball circulation plate 30 is formed into a substantially triangular shape as described above. Therefore, when the ball circulation plate 30 is pressed against the force of pressing the skirt portion 23 of the moving block 20, the ball circulation plate 30 The position of the track rail 10 in the height direction (upper and lower direction of the paper) is set to -10- (8) 1375758 in the receiving groove 26 of the skirt portion 23, with the result that the position of the moving block 20 in the height direction is relative to The track rails 10 form a position. As shown in Fig. 5, the ball groove 13 of the track rail 10 and the load straight groove 32 of the ball circulation groove 31 opposed thereto are formed in a Gothic arch shape, and the ball 2 is in contact with each other. In these trenches. The ball 2 and the ball groove 13 or the contact direction with the load straight groove 32 are inclined at a height of 45 degrees from the normal direction of the side surface of the track rail 1 ,, and are formed to be loadable with respect to the movement block 2〇. Any load outside of its direction of movement. That is, the ball groove 13 of the track rail 10 and the load straight groove 32 of the ball circulation plate 30 are opposed to each other, thereby forming a load rolling passage of the ball 2, and the passing ball 2 is rolled in the load rolling passage, so that The moving block 20 holding the ball circulation groove 31 becomes freely reciprocable along the rail rail. On the other hand, the unloaded linear groove 33 of the ball circulation plate 30 and the ball holding groove 14 of the rail rail 10 have a cross section which is also formed in a Gothic style arch. The distance between the ball holding groove 14 of the track rail 10 facing each other and the unloaded straight groove 33 on the side of the moving block 20 is set to be larger than the diameter of the balls 2 accommodated in the ball circulation groove 31, so that the balls 2 and Between the track rails 1 〇, a slight gap is created between the balls 2 and the moving blocks 20. Therefore, the ball 2 is formed so as to be rolled in the unloaded straight groove 33 in the unloaded state by the ball holding groove 14 of the track rail 1〇, whereby the ball 2 is held in the unloaded straight groove 33. That is, the unloaded straight groove 33 of the ball circulation plate 30 and the ball holding groove 14 of the track rail 1〇 are opposed to each other, thereby forming a no-load rolling passage of the balls 2. -11 - (12) 1375758 Diameter circulation > 2, is the 20th single bend of the province of Binhe. 4 1 is limited to rolling guides with large ball diameters, for example, for the use of balls with a diameter of 1 mm or less. In the case of the extremely small rolling guide device, there is also an example shown in Fig. 1, in which the ball-bearing groove 14 is formed in the rail rail 10, and the ball retaining groove 14 and the ball ring plate are disposed on the side of the rail rail 1 The unloaded straight grooves 33 on the 30 side face each other, and the unloaded straight groove 33 of the ball returning plate 30 is formed to be shallower than the direction changing groove 34. As shown in Fig. 5, it is configured to circulate in the ball circulating groove 31. The balls enter the unloaded straight groove 33 as it goes from the direction changing groove 34, and then gradually float on the surface of the ball circulation plate 30. However, as shown in Fig. 6, the unloaded straight groove 33 to be formed into the ball circulation groove 31 may be formed so as to continuously form a depth groove from the deepest portion of the direction change groove 34, so that the load straight groove 3 3 and the track rail are formed. The sides of the 〇 are opposite to each other to form a non-negative rolling channel. When the configuration is as described above, the ball retaining groove 14 can be formed slightly on the rail rail 10, and the processing of the rail rail 1〇 can be easily performed. Further, in the example shown in Fig. 1, a pair of stoppers is stopped. The members 40 40 are individually screwed to the front and rear end faces of the moving block 20, but as shown in Fig. 7, the stopper members 40 and the pair of side seals 25 to be fixed to the skirt portion 23 of the moving block may be The unitary body is formed to form the sealing member 50. The sealing unit 50 is formed by folding a metal sheet after press working, and a rubber seal which is an end seal and a side seal 25 to be in contact with the rail rail 10 is fixed at a predetermined position of the metal plate. The jig fits the moving block 20 to the sealing unit 50, and the fixing of the side seals 25 and the end seals 4 1 can be fixed at a position of -15 - 8 (14) 1375758. The groove 72 is toward the ball. The end faces of the circulation plate 70 are open. The cross-sectional shape of the load straight groove 71 and the unloaded straight groove 72 is the same as that of the first embodiment, and the load straight groove 71 of the ball circulation plate 70 and the ball groove 13 of the track rail 10 are opposed to each other to form the ball 2 Load roller channel. On the other hand, the unloaded linear groove 72 of the ball circulation plate 70 and the ball holding groove 14 of the track rail 10 are formed to face each other to form a non-load roller passage of the ball 2. On the other hand, the end cover 60 to be fixed to the end surface of the moving block 20 is formed with a direction changing groove 61 which allows the load rolling passage of the ball 2 and the no-load rolling passage to form a continuous connection. That is, when the pair of end caps 60 are fixed to the moving block 20, as shown in FIG. 1, the load straight groove 71 and the no-load straight groove 72 of the ball circulation plate 70 are transmitted through the direction change 61 of the end cover 60 to form a communication connection. This completes the infinite loop of the ball 2. In order to introduce the balls 2 which are rolled in the ball rolling grooves 13 of the rail rails 10 while being loaded with the load, the direction changing grooves 61 are gradually changed from the connection portion with the load straight line # groove 71. Deep, the deepest portion is formed at a position facing the flat portion 15 of the rail rail 10. Then, the depth gradually becomes shallow as it approaches the unloaded straight groove 72, and finally forms a connection with the unloaded straight groove 72. That is, the direction changing groove 61 is formed on the end cover 60 in the original shape of the direction changing groove 34 formed in the ball circulation plate 30 of the first embodiment. Further, the end cap 60 is provided with an end seal 62 to seal its gap with the rail rail 10. Then, in the rolling guide device of the second embodiment, the roller 8 -17-(16) 1375758 is protruded in the columnar shape on the back surface of the ball circulation plate 80, and the skirt portion 23 of the moving block 20 is formed as described above. The locking groove 84 of the engaging projection 81 is in sliding contact with the head. Further, a gap is formed between the inner side surface of the skirt portion 23 and the back surface of the ball circulation plate 80, and the ball circulation plate 80 is configured to be opposed to each other according to the load acting on the rolling bead 2 which is rolled in the load straight groove 82. The skirt 23 is inclined. According to the rolling guide device described above, the two-axis rolling guide device is disposed in parallel on the mounted portion such as the machine tool or the column, and the moving block 20 of the rolling guide device is fixed to a movable body such as a common platform to constitute a movement. In the case of the platform unit, the service life of the rolling guide can be lengthened, and the reduction in sliding resistance can be achieved. That is, if there is a machining error in the mounting surface of the rail or the like of the machine tool or the column or the moving block mounting surface of the movable body such as the platform, the bending load will act on the rail rail 10 and after the assembly of the moving platform is completed. Between the moving blocks 20, among the plurality of ball rows existing in the moving block 20, only the specific ball row has an early wear ratio, and the sliding resistance of the moving block 20 on the track rail 10 also tends to increase. However, the example "not shown in Fig. 13" is such that the ball circulation plate 8 is configured to be inclined to the skirt portion 23 in accordance with the load to be applied to the balls 2 that are rolled in the load straight groove 82, according to the track. The machining error of the rail mounting surface or the moving block mounting surface, the ball circulation plate 80 is inclined to the skirt portion 23, and the excessive load is relieved to act on the specific ball 2. As a result, it is possible to prevent the ball 2 from being abnormally worn, and the rolling guide can be extended in life. The sliding resistance of the moving block 20 sliding on the track rail 1 can be reduced. -19- (17) 1375758 Fig. 14' is a cross-sectional view showing a fourth embodiment of the rolling guide device of the present invention. In the rolling guide device of the fourth embodiment, the inner side surface of each of the skirt portions 23 of the moving block 2 is formed into a concave curved surface 91 having a constant curvature, and the pair of ball circulation plates 90 are formed to conform to the concave surfaces. The shape of the curved surface 91. In other words, the ball circulation plate 90 is formed in a substantially flat shape, and a Φ ball circulation groove formed by the load straight groove 92, the unloaded straight groove 93, and the direction change groove is formed on the surface thereof, and the back surface is formed on the back surface. A convex curved surface 94 in which the concave curved surfaces 91 of the skirt portions 23 of the moving block 20 coincide with each other. The length of the concave curved surface 91 of the skirt portion 23 in the arc direction is longer than the length of the convex curved surface 94 of the ball circulation plate 90 in the arc direction, so that the ball circulation plate 90 is configured to be freely movable along the concave curved surface 91 at the skirt portion 23. Inner side. The center of curvature of the concave curved surface 91 of the skirt portion 23 is located at the center of the four rows of balls 2 to be rolled in the load straight groove 92 and the unloaded straight groove 93. Therefore, even if the shifting movable block 2 is slightly inclined to the track rail 10 in the state of being slightly inclined along the axis of the track rail 10, it is fixed to the movable body 'but the ball circulation plate 90 is along The concave curved surface 91 of the skirt 23 is moved to absorb the bending moment load generated between the rail rail 10 and the moving block 20. In this way, even if the mounting surface of the track rail 10 is inferior in accuracy, it is possible to prevent an excessive load from acting on the balls 2, and the movement of the moving block 20 to slide on the track rails 10 can be smoothly performed. According to the present invention described above, the moving block 20 can be easily provided with the infinite number of passages of the balls 2, and the number of parts to be passed or the number of processing units can be reduced, so that the rolling guide can be manufactured simply and inexpensively. -20- (18) 1375758 • [Simplified Schematic Description] Fig. 1 is an exploded perspective view showing a first embodiment of a rolling guide device to which the present invention is applied. ^ Fig. 2 is a rolling guide shown in Fig. 1.
