Description

  The present invention relates to an end cap used by being fixed to an end portion in a linear motion direction of a slider main body of a linear guide device.

  The linear guide device includes a guide rail, a slider, and a plurality of rolling elements. The guide rail and the slider have a rolling groove (a rolling surface when the rolling element is a “roller”) that are arranged to face each other and form a rolling passage of the rolling element. The slider further includes a return path for the rolling elements and a direction changing path for communicating the return path and the rolling path. The rolling path, the return path, and the direction changing path constitute a circulation path of the rolling element, and the rolling element circulates in the circulation path so that one of the guide rail and the slider is relative to the other. Move in a straight line.

In the slider of such a linear guide device, an end cap is fixed to the end portion of the slider body in the linear movement direction. The end cap includes leg portions disposed on both sides in the width direction of the guide rail, and a trunk portion that extends in a direction orthogonal to the both leg portions and connects the both leg portions. And the outer side groove | channel of the direction change path of a rolling element is formed in the surface at the side of the slider main body of both leg parts.
An oil supply port is formed in the body portion of the end cap, and an oil groove extending from the oil supply port toward the direction change path is formed on the surface on the slider body side. The oil groove is formed in a state where a second oil groove extending in parallel with each leg portion is connected to both ends of the first oil groove extending along the trunk portion, and the second oil groove is formed as a return guide. Are connected to the outer groove of the direction change path through an oil groove or the like. Then, by attaching an end cap to the slider body, an oil passage is formed by the oil groove of the end cap and the surface of the slider body.

In such a linear guide device, it is necessary to prevent the lubricating oil from leaking from the contact surface between the main body of the slider and the end cap. Since the slider body is usually made of metal and the end cap is made of synthetic resin, a large slider often has a gap between the contact surfaces.
In addition, a synthetic resin protrusion that closes the gap is also provided on the end cap, but even with this method, it is possible to prevent any lubricant from leaking from the contact surface between the slider body and the end cap. Can not.

Therefore, for example, a gasket having the same surface shape as the main body side surface of the end cap is sandwiched between the end cap and the slider. Patent Document 1 below describes that a cured product of an oil-resistant paste-like sealant is disposed around an oil groove formed on the surface of the end cap on the slider body side along the oil groove. ing.
JP 2004-225758 A

  The present invention has been made to solve such problems of the prior art, and aims to prevent leakage of lubricating oil from the contact surface between the slider body and the end cap of the linear guide device. To do.

  In order to solve the above-described problems, the present invention is used by being fixed to the linear motion device end of the linear movement of the slider body, and is disposed on both sides of the guide rail in the width direction, and is orthogonal to both legs. A body portion extending in a direction and connecting both leg portions, and introducing a lubricant supplied to an outer groove of a direction change path of a rolling element and an oil supply port into the direction change path on the surface of the slider body. An end cap in which an oil groove is formed, wherein the oil groove is formed in a recessed portion whose periphery is lower than the surface on the slider main body side and shallower than the depth of the oil groove, and a plate-like portion corresponding to the recessed portion; Provided is an end cap for a linear guide device, comprising a cover material in which a convex portion corresponding to a groove is integrated.

According to the end cap of the present invention, the oil groove and the convex portion are formed by fitting the convex portion of the lid member into the oil groove formed on the surface on the slider body side and fitting the plate-like portion into the concave portion. An oil passage is formed in a sealed state.
Therefore, according to the slider assembled using this end cap, the lubricating oil is prevented from leaking from the contact surface between the slider body and the end cap.

  In the end cap of the present invention, the oil groove is formed in a state in which the second oil groove extending in parallel with each leg portion is connected to both ends of the first oil groove extending along the trunk portion. The oil passage is composed of a first oil passage formed by a first oil groove and a convex portion of the lid member, and a second oil passage formed by a second oil groove and the convex portion of the lid member. It is comprised and the 2nd oil path is connected to the both ends of the 1st oil path.

In this case, when the dimension in the height direction of the convex portion of the lid member is a portion corresponding to the boundary position between the second oil groove and the first oil groove, it is larger than the other portions ( The oil passage formed by attaching the lid member to the recess of the end cap is a cross-sectional area of the second oil passage at a boundary position between the first oil passage and the second oil passage. Becomes smaller than the first oil passage.
In this case, if the bottom of the oil groove is formed higher than the other part at the boundary position between the second oil groove and the first oil groove (the end cap according to claim 3). ), The oil passage formed by attaching a lid material to the recess of the end cap is the boundary position between the first oil passage and the second oil passage, and the cross-sectional area of the second oil passage is the first oil passage. Smaller.

  Here, when the linear guide device is mounted with the slider body portion disposed horizontally and the lubricant is supplied from the oil supply port on one side surface of the end cap body portion, the first oil passage is formed on the oil supply side of the oil passage. When the cross-sectional area at the boundary position between the first oil passage and the second oil passage is the same, the lubricant is likely to fall through the second oil passage on the oil supply side by the action of gravity, and difficult to face the first oil passage. It is easy to become. On the other hand, as described above, when the cross-sectional area of the second oil passage is smaller than that of the first oil passage at the boundary position between the first oil passage and the second oil passage, It becomes easy for the lubricant to face not only the second oil passage but also the first oil passage.

Thus, even with the above-described arrangement and oil supply method, by using the end cap according to claims 2 and 3 of the present invention, the lubricant is brought from one end of the first oil passage to the other end. Can be distributed over the oil passages of both legs.
Further, when the configuration of the oil groove is as described above, the height dimension of the convex portion of the lid member corresponds to the boundary position between the first oil groove and the second oil groove. If formed larger (end cap of claim 4), the oil passage formed by attaching the lid member to the recess of the end cap is the boundary position between the first oil passage and the second oil passage, The cross-sectional area of the first oil passage is smaller than that of the second oil passage.
Further, in the same case, when the height of the bottom surface of the oil groove is higher than the other part at the boundary position between the first oil groove and the second oil groove (the end cap according to claim 5). ), An oil passage formed by attaching a lid member to the recess of the end cap is a boundary position between the first oil passage and the second oil passage, and the cross-sectional area of the first oil passage is the second oil passage. Smaller.

Here, when both the legs of the slider are arranged in the vertical direction, the linear guide device is attached, and when lubricant is supplied from the oil supply port arranged on the upper side of the side surface of the end cap, the oil supply side of the oil passage If the cross-sectional area at the boundary position between the first oil passage and the second oil passage is the same, the lubricant can easily fall down the first oil passage extending in the vertical direction by the action of gravity, and It tends to be difficult to face the second oil passage. On the other hand, as described above, when the cross-sectional area of the first oil passage is smaller than that of the second oil passage at the boundary position between the first oil passage and the second oil passage, Not only the first oil passage that extends, but also the second oil passage disposed on the upper side, the lubricant can easily face.
Thereby, even if it is the above-mentioned arrangement | positioning and the oil supply method, it can be made to distribute a lubricant to the oil path of both leg parts by using the end cap of Claim 4 and 5 of this invention.

  According to the end cap of the linear guide device of the present invention, it is possible to prevent the lubricating oil from leaking from the contact surface between the slider body and the end cap.

Hereinafter, an end cap corresponding to an embodiment of the present invention will be described.
FIG. 1 is a view showing a surface (front side) of the end cap 1 of this embodiment on the slider main body side, and shows a state before the lid member 2 is fitted into the recess 3.
2A and 2B are views showing the lid member 2 of this embodiment, where FIG. 2A is a plan view, FIG. 2B is a view showing a surface that fits into a recess, and FIG. It is A sectional drawing.

FIG. 3 is a view showing a state in which the lid member 2 is fitted in the recess 3 of the end cap 1 of FIG.
4 is an enlarged view of the BB cross section of FIG. FIG. 5 is an enlarged view of the CC cross section of FIG.
As shown in FIG. 1, the end cap 1 includes leg portions 11 disposed on both sides of the guide rail in the width direction, and a trunk portion 12 that extends in a direction orthogonal to the leg portions 11 and connects the leg portions 11. The outer groove 13 of the direction change path of the rollers (rolling elements) is formed on the surface of the both leg portions 11 on the slider main body side. The outer groove 13, the first return guide 131 and the second return guide 132 form a direction change path for the rollers (rolling elements).

  A first oil groove 14 a extending along the body portion 12 and a second oil groove 14 b extending in parallel with the leg portion 11 are formed on the surface of the end cap 1 on the slider main body side. Are formed in a state where the second oil groove 14b is connected to both ends. The second oil groove 14b extends to an upper part than the first oil groove 14a. The periphery of the first oil groove 14a and the second oil groove 14b is a recess 3 that is lower than the surface on the slider body side and shallower than the depth of these oil grooves 14a, 14b.

  The end 14c of the second oil groove 14b on the outer groove 13 side is present at a position away from the recess 3. The end portion 14c communicates with the groove 132a of the second return guide 132 in a state where the first return guide 131 and the second return guide 132 are attached. Then, the lubricant in the second oil groove 14b is introduced from the end portion 14c through the groove 132a into the outer groove 13 of each direction change path.

In the center of the body portion 12 of the end cap 1, an oil supply port 15 that penetrates from the back surface of the end cap 1 to the bottom surface of the recess 3 is formed. As shown in FIG. 5, the first oil groove 14 a is connected to the oil supply port 15 at the center portion of the body portion 12. That is, the lubricating oil supplied from the central oil supply port 15 is introduced into the first oil groove 14 a from the lower portion of the oil supply port 15.
The corners of both side walls of the first oil groove 14a and the second oil groove 14b are slopes 14d that spread toward the opening side. The inclined surface 14 d is also formed continuously in a semicircular portion that forms the upper half of the fuel filler opening 15.

  Further, oil filler ports 16 are also formed on both side surfaces of the body portion 12. These oil supply ports 16 and the upper ends of the second oil grooves 4 b are connected by oil supply holes 17. Although the space between the oil supply hole 17 and the oil supply port 16 is closed, the tip of the oil supply port 16 has a shape that allows the oil supply hole 17 and the oil supply port 16 to communicate with each other by strongly pushing the tip of the oil supply nozzle. . The end cap 1 is also formed with through holes 18 and 19 through which bolts for fixing to the slider body are bolted.

As shown in FIG. 1, the planar shape of the concave portion 3 of the end cap 1 is such that the through hole 19 portion of the body portion 12 is avoided in a U shape, includes the oil filler port 15, and the end portion on the leg portion 11 side is narrowed. It is a shape like this. The end cap 1 is formed with a positioning recess 31 at a depth shallower than the recess 3 so as to reach the center of the body 12 up to the lower end of the body 12.
As shown in FIG. 2, the lid member 2 includes a plate-like portion 21, convex portions 22 a to 22 c that protrude from one surface of the plate-like portion 21, and a positioning protrusion 23 that protrudes from the lower end surface of the plate-like portion 21. It is formed integrally. The planar shape of the plate-like portion 21 is the same as the planar shape of the concave portion 3 of the end cap 1. That is, the plate-like portion 21 has a U-shaped portion 21 a that avoids the through hole 19 and a narrowed portion 21 b at the end on the leg portion 11 side. A slope 21c is formed on the outer edge of the surface of the plate-like portion 21 where the convex portions 22a to 22c are formed.

The convex portion of the lid member 2 is composed of a convex portion 22a corresponding to the first oil groove 14a, a convex portion 22b corresponding to the second oil groove 14b, and a convex portion 22c corresponding to the oil supply port 15. A slope 22d corresponding to the slope 14d of the oil groove is formed.
The positioning projection 23 is provided below the convex portion 22c, and is formed thinner than the plate-like portion 21 by the height of the inclined surface 21c as shown in FIG.

  As shown in FIG. 3, the end cap 1 of this embodiment is used with a lid 2 fitted in a recess 3. At that time, the positioning projection 23 of the lid member 2 is aligned with the recess 31 of the end cap 1, and the plate-like portion 21 is fitted into the recess 3. Thereby, the convex portions 22a and 22b of the lid member 2 are fitted in the oil grooves 14a and 14b formed deeper than the concave portion 3, and as shown in FIGS. 4 and 5, the oil grooves 14a and 14b and the convex portions 22a and 22b In the meantime, the oil passage 4 (the first oil passage 41 and the second oil passage 42) is formed in a sealed state. The oil passage 4 has the same cross-sectional area as a whole.

Therefore, it is possible to prevent the lubricating oil from leaking from the contact surface between the slider body and the end cap 1 by assembling the slider by using the lid member 2 fitted to the recess 3 of the end cap 1 of this embodiment.
2 is fitted into the recess 3 of the end cap 1 of FIG. 1, and the linear guide device is attached in the arrangement of FIG. 3 (the body of the slider is disposed horizontally). When the lubricant is supplied from the oil supply port 15 provided at the center of 12, lubrication is performed from the first oil passage 41 along the trunk portion 12 to the second oil passage 42 extending in parallel with the leg portions 11 on both sides. The drug spreads.

  However, in the same arrangement, when the lubricant is supplied from, for example, the right oil supply port 16 of the body portion 12, the second oil passage (an oil passage extending in parallel with the leg portion 11) 42 from the right oil supply hole 17. The lubricant that has entered the upper side tends to fall through the second oil passage 42 due to the action of gravity, and is unlikely to face the first oil passage (oil passage along the trunk portion 12) 41. In this case, the lid material 2A shown in FIG. 6 is used instead of the lid material 2 shown in FIG. The oil passage 41 can be easily faced.

6A is a plan view of the lid member 2A, FIG. 6B is a diagram showing a surface that fits into the recess, and FIG. 6C is a cross-sectional view taken along line AA in FIG.

  When the plate-like portion 21 of the lid member 2A is fitted into the concave portion 3 of the end cap 1 of FIG. 1 to obtain the state of FIG. 7, the first oil passage 41 has the same cross section as FIG. Of the cross section of the oil passage 42, the portions other than the convex portion 22e are the same as those in FIG. On the other hand, as shown in FIG. 8, the second oil having a smaller cross-sectional area by the amount of the convex portion 22e than the second oil passage 42 of the other portion shown in FIG. A path 42A is formed. That is, in the state of FIG. 7, the cross-sectional area of the second oil passage 42 is smaller than that of the first oil passage 41 at the boundary position between the two oil passages 41 and 42.

  Therefore, when the lubricant is supplied from, for example, the right oil supply port 16 of the trunk portion 12 in the arrangement of FIG. 7, the lubricant that has entered the upper side of the second oil passage 42 on the right side from the right oil supply hole 17 is Not only does this oil passage 42 fall, but it also becomes easier to face the first oil passage 41. Therefore, the lubricant can be extended from one end portion of the first oil passage 41 to the other end portion and spread over the oil passages 42 of both the leg portions 11.

In the above example, the end cap 1 of FIG. 1 and the lid member 2A of FIG. 6 are combined, but the same effect can be obtained by combining the end cap 1A shown in FIG. 9 and the lid member 2 of FIG.

By fitting the plate-like portion 21 of the lid member 2 of FIG. 2 into the concave portion 3 of the end cap 1A of FIG. 9 to the state of FIG. 10, the cross section of the first oil passage 41 becomes the same as FIG. In the second oil passage 42, the cross section of the portion other than the portion 14e where the bottom surface of the second oil groove 14b is high is the same as that in FIG. On the other hand, as shown in FIG. 11, the second oil groove 14b having a high bottom surface 14e has a second cross-sectional area smaller than that of the second oil passage 42 of the other part shown in FIG. An oil passage 42B is formed. That is, in the state of FIG. 10, the cross-sectional area of the second oil passage 42 is smaller than that of the first oil passage 41 at the boundary position between the two oil passages 41 and 42.

  On the other hand, when the linear guide device is attached with both legs of the slider arranged in the vertical direction, and the lubricant is supplied from the oil supply port arranged on the upper side of the side surface of the end cap, the end cap shown in FIG. 2 using the lid member 2 shown in FIG. 2 in the recess 3 of FIG. 1 (the state shown in FIG. 3), the lubricant can easily fall down the oil passage 41 along the trunk portion 12 by the action of gravity. It tends to be difficult to face the tip of the oil passage 42 on the leg 11 side arranged on the upper side (the end 14c side of the second oil groove 14b).

In this case, the lid member 2B shown in FIG. 12 is used instead of the lid member 2 in FIG. 2 as the lid member to be fitted in the recess 3 of the end cap 1, so that the lubricant is disposed on the upper side. It is also possible to make it easier to face the tip of the oil passage 42 on the 11th side (the end 14c side of the second oil groove 14b).
