The invention relates to a method for manufacturing a motion guiding device.

In the past, in motion guidance devices such as linear guides, ball spline devices, ball screw devices, etc., since the components constituting the above-mentioned devices will be accompanied by repeated rolling and sliding actions, their constituent components have generally adopted high-carbon Chrome bearing steel, stainless steel, hardened steel and other metal materials with high hardness.

However, in recent years, due to the need to expand the application range of motion guidance devices, especially the realization of lightweight devices is needed, so the proposal has a concept for reducing the weight to meet this demand. For example, Patent Document 1 described below discloses an invention for the purpose of reducing the weight of a linear guide, and is characterized in that an aluminum alloy is used to constitute a member as a guide rail of a rail member.

However, in the invention described in Patent Document 1 below, since the main components of the motion guide device are made of metal materials, as in the conventional case, even if a certain degree of weight reduction can be achieved, there is still a limit, and It is difficult to meet the recent demand for further lightweighting.

On the other hand, FRP (Fiber Reinforced Plastics) is known as a material that has the same strength and rigidity as metal materials such as steel and can also be reduced in weight. Because FRP reinforces plastics with fibers and resins, it can significantly increase the strength, so it has been used in a variety of materials including aerospace industry, motorcycles, automobiles, railways, construction industry, medical fields and so on. In addition, the applicant of the present case has studied the technology of applying FRP to the constituent members of the motion guidance device, and has proposed various inventions such as those disclosed in Patent Document 2 below.

The aluminum alloy is formed of an extruded material, and the inside of the rail 11 is formed by FRP in the form of being sandwiched by the aluminum alloy extruded material located on the outer direction side and the inner direction side. In addition, in the present embodiment, the vicinity of the rolling element rolling surface (rolling element rolling groove 11a) that is in contact with the balls 12 is formed of a metal material having high strength. With the above-mentioned characteristics, the motion guide device 10 of this embodiment can maintain the same strength and rigidity as the conventional motion guide device, and can also reduce the weight.

The structure of the rail 11 of this embodiment will be described in more detail with reference to FIG. 3. FIG. 3 is a longitudinal sectional view for explaining the structure of the track rail 11 of this embodiment.

The track rail 11 of this embodiment is formed by joining three members of two mold and outer layer members 32, a prepreg laminated body 31, and a rolling portion 30. The two mold and outer layer members 32 are composed of It is composed of an extruded material of aluminum alloy. The prepreg laminated body 31 is composed of FRP which is sandwiched between two molds and outer layer members 32 in the form of being sandwiched by two molds and outer layer members 32. This rolling part 30 is provided with respect to the mold and outer layer member 32 located in the inner direction side of a substantially U-shaped longitudinal cross-section among the two mold and outer layer members 32.

Among the two molds and outer layer members 32, the mold and outer layer member 32 located on the inner direction side of the track rail 11, that is, on the inner direction side of the installation side of the moving member 13, forms the rail rail 11 having a substantially U-shaped longitudinal section. The inner surface side member is a member having a thickness of about 1/3 to 1/5 of the thickness of the entire rail rail 11. On the inner side of the mold and outer layer member 32 on the inner side, two joint groove portions are formed to join the two rolling portions 30, and the two joint groove portions are substantially U-shaped on the inner direction side with respect to the longitudinal section. One for each of the left and right positions. In addition, since the outer surface of the mold and outer layer member 32 on the inner side is a surface to which the prepreg layered body 31 to be described later is attached, it has a smooth surface shape.

On the other hand, of the two molds and outer layer members 32, the mold and outer layer members 32 forming the outer side of the rail rail 11, that is, the left and right side surfaces and the bottom side of the rail rail 11, are formed in a longitudinal section that is roughly The U-shaped member of the side surface of the track rail 11 in the outer direction is configured as a member having a thickness of about 1/3 to 1/5 of the thickness of the track rail 11 as a whole. The inner surface of the mold and outer layer member 32 on the outer side is a surface for attaching the prepreg laminated body 31 described later, so it has a smooth surface shape, and the mold and outer layer member 32 on the outer side The outer side adopts a shape for forming the outer shape of the track rail 11. Furthermore, since the mold and outer layer member 32 and the mold and outer layer member 32 on the inner direction side of the two molds and the outer layer member 32 are made of an aluminum alloy extruded material, it is possible to achieve low cost and low cost. Manufacturing with high dimensional accuracy.

The prepreg layered body 31 is a member formed by laminating and laminating prepregs in a sheet shape using an adhesive, and then applying pressure or heating. The type of FRP used is preferably CFRP (Carbon Fiber Reinforced Plastics), GFRP (Glass Fiber Reinforced Plastics), KFRP (Kevlar Fiber Reinforced Plastics) At least one of them. In particular, CFRP is extremely excellent in strength, and can change the lamination direction or number of laminations of carbon fibers to make the desired shape strong and lightweight, so it is a better material.

Furthermore, in the motion guiding device 10 of this embodiment shown in Figs. 1, 2 and 3, although only the rail 11 is made of a metal material and FRP, the present invention is not limited to the above-mentioned implementation. The form, other members, such as the moving member 13, may also be composed of a metal material and FRP.

The basic configuration of the motion guidance device 10 according to this embodiment has been described above with reference to FIGS. 1 to 3. Next, a method for manufacturing the motion guide device 10 according to this embodiment will be described. It should be noted that the manufacturing method described below is performed on the manufacturing method of the rail 11 of the present embodiment shown in FIGS. 1 to 3. Here, FIG. 4 is a flowchart for explaining the manufacturing method of the rail 11 of this embodiment. In addition, FIG. 5 is a schematic diagram for explaining a method for manufacturing a rail rail of this embodiment corresponding to the flowchart shown in FIG. 4.

In the manufacturing method of the track rail 11 of this embodiment, first, a mold and outer layer preparation step for preparing two molds and outer layer members 32 (321, 322) is performed (step S10). As shown in part (a) of FIG. 5, the mold and outer layer member 32 (321, 322) constitutes the outer direction side (321) and the inner direction side (322) of the rail rail 11 having a substantially U-shaped longitudinal section. It is made of aluminum alloy extruded material. Since the mold and outer layer member 32 (321, 322) is an extruded material of aluminum alloy, and because it is also a relatively easy to process, lightweight, and rigid member, it is suitable as a member constituting the outline of the rail 11. Moreover, it can be easily formed into any shape by extrusion processing, and can be applied to any shape of the track member, so it is preferable.

Next, the two mold and outer layer members 32 (321, 322) prepared in the mold and outer layer member preparation step (step S10) are chemically or physically processed on the surface of the mold and outer layer member 32 (321, 322). The surface treatment step is performed to form a concave-convex shape on the surface of the mold and outer layer member 32 (321, 322) (step S11). In this surface treatment step (step S11), as shown in the partial view (b) in FIG. 5, one of the two mold and outer layer members 32 (321, 322) is located on one of the outer sides of the rail 11 in the direction direction. The mold and outer layer member 321 on the side is subjected to surface treatment on the surface on the upper surface side, and the surface of the lower surface side is applied to the mold and outer layer member 322 on the other side on the inner side of the rail 11. Surface treatment. That is, the surface on the side where the prepreg laminated body 31 to be described later is joined is subjected to a surface treatment. Furthermore, in the surface treatment step (step S11) of this embodiment, the surface of the mold and outer layer member 32 (321, 322) is chemically roughened using a chemical product such as an acid, and the mold and the outer layer member 32 are chemically roughened. (321, 322) A process having a concave-convex shape at a microscope level is formed. In this way, by forming a microscopic concave-convex shape, it is possible to increase the mold and outer layer members 32 (321, 322) and adhesion when the adhesive for prepreg material coating applied in the subsequent step enters the concave-convex shape. Agent contact area to achieve a firm bonding state.

Next, a step of laminating the prepreg 311 to the surface of one of the mold and the outer layer member 321 of the two molds and the outer layer members 32 (321, 322) by using an adhesive is carried out. (Refer to the sub-graph (c) in FIG. 5). In the present embodiment, a sheet-shaped prepreg 311 is adhered to the mold and outer layer member 321 located on one side of the outer side of the track rail 11 on the side by using an adhesive and laminated. By implementing the prepreg lamination step (step S12), the prepreg 311 is laminated to a predetermined thickness and the prepreg laminate 31 is formed.

The mold and outer layer member 322 located on the other side of the inner side of the track rail 11 is adhered by an adhesive to a layer of a predetermined thickness through a prepreg lamination step (step S12). Prepreg laminated body 31. In the other mold and outer layer member 322, in the aforementioned surface treatment step (step S11), a surface that has been subjected to a surface treatment is formed on the lower side (refer to the sub-graph (b) in FIG. 5). An adhesive is applied to the surface on the lower side and bonded to the prepreg layered body 31 to prepare a semi-molded product of the rail 11 (semi-molded product preparation step, step S13). That is, at the stage of the semi-molded product preparation step (step S13), the outline shape of the track rail 11 has been substantially completed.

Next, a heating / pressurizing step (step S14) of obtaining a molded article of the rail 11 by heating and pressing the semi-molded article prepared in the semi-molded article preparation step (step S13) is performed (see FIG. Figure 5 (e)). In the heating / pressurizing step (step S14) of this embodiment, two molds and outer layer members 32 (321, 322) are used as molds. The two molds and outer layer members 32 (321, 322) are used as the upper and lower molds (322) and (321), and are heated by applying pressure in the vertical direction while heating. The prepreg laminated body 31 is formed into an FRP having a predetermined strength. Furthermore, although the conventional FRP molding method prepares a metal mold such as aluminum and uses the mold to perform heating / pressing processing, in the heating / pressing step (step S14) of this embodiment, The method of using the mold and outer layer members 32 (321, 322) constituting the outline of the rail 11 as a mold can reduce the number of man-hours in the manufacturing steps and is excellent in productivity and cost. In addition, as for the specific method of the heating / pressing step (step S14) of this embodiment, as long as a method using a mold and outer layer member 32 (321, 322) as a mold can be used, a conventionally known FRP manufacturing method can also be applied In the present invention, for example, the heating or pressing performed in the heating / pressing step (step S14) may be performed by a method such as a press molding method, a prepreg pressing method, or the like.

Finally, the finished product obtained in the heating / pressurizing step (step S14) is subjected to finishing processing to obtain a finishing step (step S15) as a final finished product of the track rail 11. In this finishing step (step S15), as shown in the sub-figure (f) in FIG. 5, a plurality of bolt mounting holes 11b and the like required for the use of the track rail 11 are formed by processing. In addition, a rolling element rolling groove 11 a is formed by providing a raceway portion 30 made of a metal material to the mold and outer layer member 322 located on the other side of the inner side of the rail 11. By implementing this finishing step (step S15), the track rail 11 of this embodiment is completed.

Furthermore, in the motion guide device using the conventional technology of FRP, when the motion guide device is subjected to tapping processing or drilling processing in order to fix the fixing with other components, etc., there are The processing part of the FRP process may cause problems such as fiber protruding, fluffy, and burrs. However, according to the track rail 11 of the present embodiment manufactured by the aforementioned processing steps, the taps and holes provided for fixing with other members and the like are used as long as they can be used as molds at the time of manufacturing. The two molds and outer layer members 32 (321, 322) can be formed by processing, so there will be no problems such as fiber protrusion, fluff, burrs, etc. that occur when the FRP is directly processed. . Therefore, according to the present embodiment, it is possible to solve the man-hours of the retro-processing for correcting the defectiveness of the FRP, and to obtain the effect of reducing the manufacturing cost. In addition, according to this embodiment, since the two molds and the outer layer member 32 (321, 322) need only be processed to fix other parts, etc., the above configuration can be called a design limitation. Very few components. That is, compared with the conventional technique of providing tapping holes or holes to the FRP, as in the present embodiment, tapping holes or holes are provided to the mold and outer layer member 32 (321, 322) composed of aluminum alloy, and the strength is also improved. More excellent. In addition, in the processing of the mold and outer layer member 32 (321, 322) composed of aluminum alloy, since the processing of the fiber direction is not required as in the processing of FRP, the setting of taps or holes is required. There are very few restrictions on location or shape. That is, according to the present embodiment, it is possible to provide a novel motion guidance device which can achieve weight reduction, has few design restrictions, and can reduce manufacturing costs.

In the foregoing embodiment, the heating or pressing performed in the heating / pressing step (step S14) may be performed by a method such as a press molding method or a prepreg pressing method. Although it demonstrates, in the method of this invention, if it is a molding method using a mold, other FRP manufacturing methods may be used.

In the heating / pressurizing step (step S14) of the aforementioned embodiment, a method of using two molds and outer layer members 32 (321, 322) as molds is used. That is, the two molds and the outer layer member 32 (321, 322) are used as the upper mold (322) and the lower mold (321) which are disposed on the upper and lower molds, and are heated while applying pressure in the vertical direction, and The prepreg laminated body 31 is formed into an FRP having a predetermined strength. However, in the present invention and the method of the present invention, a configuration in which one mold and the outer layer member 32 are used and only one of the upper mold (322) and the lower mold (321) can be used.
