Description

  The present invention relates to a linear guideway, and more particularly, to a disclosure of a structure form of a novel linear guideway having concave grooves arranged in parallel to the rail.

  In practice, the components of the linear guideway are usually mounted in such a manner that the rail is fitted in a fixed groove set in advance on the rail seat, and then positioning is performed with the rail mounted on the rail seat. It is necessary to perform pressure processing with a processing apparatus.

  However, even though positioning was obtained with the rails of a conventional linear guideway, it was discovered that there are still some problems and disadvantages in the subsequent operational use experience. In other words, between the conventional rail and the slide rail seat belongs to a smooth surface and is in a close fitting state with each other, so when facing a relatively heavy load during the subsequent use of the linear guideway In addition, the displacement position of each other can frequently occur due to insufficient frictional force between the two. For this reason, problems and shortcomings such as shortened service life and reduced guide rolling accuracy due to poor structural robustness and insufficient stress strength of linear guideway products are surely made by related industries. This is an important technical issue to be overcome.

  The main object of the present invention is to provide a rail having concave grooves arranged in parallel, and the technical problem to be solved is how to make the original linear guideway more ideal and practical. The aim is to break through innovation with the goal of researching and developing structural forms.

  According to the technical feature for solving the problems of the present invention, the rail extending mainly along the axial direction includes a roller guide rolling surface, an outer surface spaced from the roller guide rolling surface, and a roller guide.

  Another main object of the present invention is to provide a linear guideway having a rail seat and a rail having concave grooves arranged in parallel. On the structure of the rail seat, at least a pair of the rails are mounted and positioned at intervals, and the rail seat is positioned by fitting closely to the corresponding rail at a position for mounting and positioning each rail.

  1 to 4 show preferred embodiments of the rail having concave grooves arranged in parallel and the linear guideway using the same according to the present invention, but these embodiments are used only for explanation. The scope of the utility model registration request is not limited to these structures.

  The rail 10 extends along the axial direction, and includes a roller guide rolling surface 11, an outer surface 12 spaced from the roller guide rolling surface 11, and between the roller guide rolling surface 11 and the outer surface 12. And two base material surfaces 13 opposite to each other, of which the roller guide rolling surface 11 includes a roller guide groove 115. Each base material surface 13 is provided with a plurality of grooves 14 arranged at predetermined intervals along the extending direction in the axial direction, and the extending direction of each groove 14 is the axis of the rail 10. Each of the concave grooves 14 includes an inner edge 143 and a lateral groove end 145. The lateral groove end 145 extends from the base material surface 13 and reaches a part of the roller guide rolling surface 11.

  As shown in FIG. 2, in this example, the groove interval W1 formed between the two adjacent grooves 14 is larger than the width W2 of the grooves 14, and the magnitude relationship disclosed in this example. However, in this example, the groove interval W1 between the two grooves 14 is the groove 14 in consideration of the influence on the structural strength of the rail 10 while mainly considering the installation of the groove 14. The magnitude relationship larger than the width W2 is adopted as a preferred embodiment. As a result, it is also possible to minimize the influence on the structural strength of the rail 10 on the assumption that the concave groove 14 has a reasonable frictional action (註: gear type and toothed). In the case of a configuration in which the front surface and the tooth base surface are provided with the same width, the structure strength and deformability of the rail 10 are relatively large).

  As shown in FIGS. 1 to 3, in this example, the base material surface 13 is set in a slanted slope shape corresponding to the region where the concave groove 14 is provided, and the roller guide rolling surface is accordingly changed. 11 is defined, and the depth of the concave groove 14 is configured with a relative difference in depth, and the relatively shallow portion thereof corresponds to the downward gradient portion 15. .

  As shown in FIG. 2, in this example, the extending direction of the groove 14 intersects the axial direction of the rail 10 perpendicularly to each other.

  As shown in FIG. 2, in this example, the plurality of grooves 14 are arranged in parallel to each other. The plurality of grooves 14 are formed in parallel with each other in order to employ pressure processing with a wheel in order to realize specific molding. The concave groove 14 can also be modified to different embodiments. For example, two sets of oblique concave grooves 14 parallel to each other can form a cross-shaped concave groove.

  As shown in FIGS. 4 and 5, the present invention further provides a linear guide way A. This includes a rail seat 20 and the rail 10 having the concave grooves arranged in parallel as described above, and on the structure of the rail seat 20, at least a pair of the rails 10 are mounted and positioned at intervals, and the rail The seat 20 is provided with a fixing groove 21 used for closely fitting and positioning the corresponding rail 10 at a position for mounting and positioning each rail 10. On both sides of the opening of each of the fixed grooves 21, pressing protrusions 22 are formed that are used for tightly attaching the base material surface 13 of the rail 10 and the roller guide rolling surface 11 to adjacent portions. .

  As shown in FIG. 6, an inner wall portion 23 is partially fitted into the concave groove 14 on the wall surface of the fixing groove 21 provided in the rail seat 20 corresponding to the base material surface 13 of the rail 10. The

  According to the above structural assembly form and technical features, the rail and the linear guideway disclosed in the present invention are mainly applied to each base material surface 13 of the rail 10 with a predetermined interval in practical application. A plurality of concave grooves 14 to be arranged are provided, and the lateral groove end 145 of each concave groove 14 uses a novel structure that extends from the substrate surface 13 and reaches a part of the roller guide rolling surface 11. To do. Accordingly, the concave and convex grooves 14 arranged in parallel form the concavo-convex stretch on the base material surface 13 of the rail 10 to obtain a surface having a very good frictional anti-slip action. As a result, when the rail 10 is incorporated in the fixed groove 21 provided in the rail seat 20, the rail 10 has a very good anti-friction anti-slipping function that the concave grooves 14 arranged in parallel have. A more robust positioning state can be achieved in combination with the rail seat 20. The possibility that the axial displacement of the rail seat 20 of the rail 10 is changed can be effectively greatly reduced. In terms of manufacturing, as shown in FIGS. 7 and 8, when the rail 10 is incorporated in the rail seat 20 and press-bonding is performed by the press wheel set 30, the concave groove 14 adds the pressure. It is possible to further accelerate the process of deforming and flowing the crushing (crimping) material, and the crushing material can be smoothly pushed into the concave groove 14 through the guide of the lateral groove end 145. For this reason (see arrow L1 shown in FIG. 8), an inner wall portion 23 to be inserted into the groove 14 is formed. As can be seen, the concave groove 14 including the lateral groove ends 145 also shows surprising benefits and advantages over the pressing process of the pressure bonding between the rail 10 and the rail seat 20.

(Explanation of effect)
The “rail having a concave groove and the linear guideway using the same” disclosed in the present invention are based on the conventional characteristic referred to in the “background art” mainly due to the above-described novel and unique structure and technical features. Compared to the structure, the coefficient of friction in the combined positioning state between the rail of the linear guideway and the rail seat can be greatly improved. Accordingly, the structural robustness and stress strength of the linear guideway product can be greatly improved, and there are many practical advantages such as extending the service life and increasing the guide rolling accuracy.

  On the other hand, the present invention is a case where the rail is incorporated into the rail seat and pressure-bonded by the technical feature that the side groove end of the concave groove extends from the base material surface and reaches a part of the roller guide rolling surface. Since the process of deforming and flowing the material of the pressure processing (caulking) is crushed by the concave groove can be further accelerated (註: the material of the crushed pressure processing is guided through the side groove end) Since it can be smoothly pushed into the concave groove), better assembly quality of the component parts can be obtained.
