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, and the oil filler opening is formed in the trunk | drum. The end cap is formed with an oil passage from the oil supply port toward the direction change passage.

  The following Patent Document 1 discloses an invention in which an oil passage is formed in an end cap by providing a recess on the slider body side surface of the body portion of the end cap and fitting a block body in which an oil passage is formed in the recess. It is disclosed. In the present invention, the bottom surface of the recess and the oil passage forming surface of the block body are provided by providing a convex portion along the oil passage on the oil passage forming surface of the block body and pressing the convex portion against the bottom surface of the concave portion to cause elastic deformation. This prevents the lubricating oil from leaking from the joint surface.

Such an end cap in which the block body in which the oil passage is formed is fitted into a recess provided on the slider body side surface of the body portion, from the joint surface between the bottom surface of the recess and the oil passage formation surface of the block body. In order to prevent leakage of the lubricating oil, it is preferable that the block body is made to adhere to the bottom surface of the recess by forming the block body with a thermoplastic elastomer or rubber.
However, it is difficult for the block body formed of thermoplastic elastomer or rubber to maintain the shape of the oil passage. In order to maintain the shape of the oil passage, it is preferable to use a hard material such as a thermoplastic resin. However, in this case, since it is difficult to obtain adhesion, lubricating oil leakage tends to occur. Therefore, for example, as shown by hatching in FIG. 16, after applying the liquid sealing material S along the edge of the block body 3 and the oil passage 33, the block body 3 is fitted into the recess of the end cap and cured. Things have been done.

In addition, when the linear guide device is used with both legs of the slider arranged vertically, the lubricating oil flows downward due to its own weight, and therefore flows into the oil passage extending downward from the oil filler port. Although it is easy, there is a problem that it is difficult to flow into the oil passage extending upward from the fuel filler opening. To solve this problem, as shown by shading in FIGS. 16 and 17, a plug U that restricts the flow rate of the lubricating oil is provided directly below or at the lower end of the oil supply port 31 of the oil passage 33 of the block body 3. If it arrange | positions, compared with the case where the plug U is not arrange | positioned, it will be thought that a lubricant becomes easy to go to the upper oil path 33 from the oil supply port 31. FIG.

However, as described above, there is room for improvement in terms of workability and work efficiency in the method of applying and drying a liquid sealing material or attaching a plug to an oil passage.
An object of the present invention is an end cap in which a block body in which an oil passage is formed is fitted in a recess provided on a surface of a body portion of a slider body, and has adhesion to the recess of the block body. Is a structure having a structure in which the lubricant is easy to be directed to the upper oil passage when used in a vertical direction by a method excellent in workability and work efficiency.

  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 part extending in the direction and connecting both leg parts, and on the surface of the slider body side of the both leg parts, an outer groove of the direction change path of the rolling element is formed, and an oil filler opening is formed in the body part, An oil passage from the oil supply port toward the direction change path of each leg is formed, a concave portion is formed on the surface of the body portion on the slider body side, and a block body in which the oil passage is formed in the concave portion. An end cap that is fitted with an oil passage forming surface facing the bottom surface of the recess, and is a plate made of a soft elastic material having oil resistance and disposed between the bottom surface of the recess and the oil passage forming surface of the block body This plate material is fitted into the oil passage to reduce the flow rate of the lubricant. Providing an end cap of a linear guide device, characterized in that it has a convex portion which limit.

  Examples of the soft elastic material having oil resistance include thermoplastic elastomers and rubbers. Specific examples of thermoplastic elastomers include thermoplastic polyester elastomer "Perprene (registered trademark)" manufactured by Toyobo Co., Ltd., and thermoplastic polyether ester elastomer "Hytrel (registered trademark)" manufactured by Toray DuPont. It is done. Specific examples of rubber include nitrile rubber and fluororubber.

  The end cap is used by fitting the projecting portion of the plate material at a position below the vertical center of the oil passage in the arrangement when the leg portions of the slider are arranged in the up-down direction. As a result, the flow rate of the lubricant to the lower oil passage is limited, so that the lubricant is easily directed to the upper oil passage. In addition, since the plate member made of a soft elastic material having oil resistance is arranged between the concave portion of the trunk portion and the block body, the block body comes into close contact with the concave portion, so that the lubricating oil leakage can be prevented.

  The present invention is also used by being fixed to the linear movement device at the end of the linear movement direction of the slider body, the leg portions disposed on both sides of the guide rail in the width direction, and extending in the direction perpendicular to the both leg portions. An outer groove of the direction change path of the rolling element is formed on a surface of the both leg portions on the slider body side, and an oil supply port is formed at the center in the width direction of the body portion. An oil passage from each leg portion toward the direction change path is formed, and a concave portion is formed on a surface of the body portion on the slider body side, and a block body in which the oil passage is formed in the concave portion is an oil passage formation. It is an end cap fitted with the surface facing the bottom surface of the concave portion, and is provided between a bottom surface of the concave portion and an oil passage forming surface of the block body, and comprises a plate material made of a soft elastic material having oil resistance, This plate material is fitted to one of the both sides of the oil passage across the oil supply port. A linear guide device characterized in that it has convex portions that restrict the flow rate of the lubricant at the same position on both surfaces, and has concave portions into which the convex portions are fitted on both sides of the oil supply port of the concave portion. Provide end caps.

When the end cap is used by arranging both the leg portions of the slider in the vertical direction, one end of the plate member is fitted below the oil supply port of the oil passage, and the other projection corresponds to the end. Fit into the dent and use. As a result, the flow rate of the lubricant to the lower oil passage is limited, so that the lubricant is easily directed to the upper oil passage. In addition, since the plate member made of a soft elastic material having oil resistance is arranged between the concave portion of the trunk portion and the block body, the block body comes into close contact with the concave portion, so that the lubricating oil leakage can be prevented.
Furthermore, the convex part which fits in one side of both sides of the oil supply port of the oil passage has the same position on both sides of the plate material, and the concave part into which the convex part fits is sandwiched between the oil supply port of the concave part. Since the end cap is provided on both sides, the end cap can be in a state in which the convex portion is fitted in the oil passage below the oil supply port, regardless of whether the end cap is disposed at both ends of the slider body in the linear movement direction.

According to the end cap of the present invention, the adhesion between the block body and the recess is obtained by interposing a plate made of a soft elastic material having oil resistance, and both the legs of the slider are provided by the projection provided on the plate. End cap assembly compared to the previous example using the liquid sealing material and plug, because the lubricant is easily oriented to the upper oil passage when the part is used in the vertical direction. The workability and work efficiency are increased.
In particular, the end cap according to claim 2 can also be used as both ends of the slider body in the linear motion direction.

As shown in FIG. 2, a recess 12 having a shape into which the block body 3 of FIG. 3 is fitted is formed on the surface of the end cap body 10 on the slider body side. The concave portion 12 mainly includes a portion corresponding to the body portion 11, has a leg portion 12 b extending from the portion toward both the leg portions 13, and further has a positioning portion 12 a of the block body 3.
In the end cap body 10, the outer groove 14 of the direction change path of the rolling element is formed on the surface of the both legs 13 on the slider body side. By fitting the return guide 14a into the outer groove 14, a direction changing path is formed. An oil supply port 15 is formed at the center of the body portion 11. In addition, a through hole 16 through which a bolt for fixing the end cap to the slider body 2 with a bolt is formed in the body portion 11 and the leg portion 13.

  In the leg portion 13, an oil passage 17 is formed from the leg portion 12 b of the concave portion 12 toward the direction change path. The through hole 16 and the oil filler port 15 of the body part 11 are formed in the recess 12. On the bottom surface 121 of the recess 12, recesses 123 a and 123 b are formed on both sides of the fuel filler opening 15 so that the protrusion 43 of the plate 4 fits tightly. In addition, oil supply ports 18 are also formed on both side surfaces of the body portion 11, and an oil supply passage 18 a at the tip of the oil supply port 18 reaches the side surface 122 of the recess 12, but the oil supply passage 18 a is closed.

As shown in FIG. 3, the block body 3 is formed with an oil supply port 31 that communicates with the oil supply port 15 of the trunk portion 11 and a through hole 32 that communicates with the through hole 16 of the trunk portion 11. An oil passage 33 is formed on the surface of the block body 3 on the concave portion 12 side.
The oil passage 33 includes a portion 33a that extends straight from the oil supply port 31 to both sides, a portion 33b that is continuous with the tip and bent so as to pass below the through hole 32 (the leg portion 13 side), The portion 33c extends downward to reach the lower end surface of the block body 3, the portion 33d extends upward, and the portion 33e extends along the thickness direction on the lower end surface of the block body 3. The upper portion 33 d extends from the outside of the through hole 32 to reach both end surfaces in the width direction of the block body 3.

Further, on the lower surface of the block body 3, a protrusion 34 that fits into the positioning portion 12 a of the recess 12 is formed. The block body 3 is obtained by injection molding a thermoplastic resin.
As shown in FIG. 4, the plate member 4 has the same surface shape as the bottom surface 121 of the recess 12, and through holes 41 and 42 are formed at positions corresponding to the oil supply port 31 and the through hole 32 of the block body 3. . Further, a rectangular convex portion 43 is fixed to one of both sides across the central through hole 41. This convex part 43 is arrange | positioned in the same position of both surfaces of the board | plate material 4, and has a dimension which fits into the oil path 33a of the block body 3 in depth direction and width direction. The plate material 4 is made of a thermoplastic elastomer, and the convex portion 43 is made of felt. Felt is a material that can absorb and retain a certain amount of lubricant. The convex portion 43 is fixed to the plate material 4 with an adhesive.

As shown in FIG. 5, the end cap 1 </ b> A of FIG. 1 has one convex portion 43 fitted in the right-side recess 123 a and the plate member 4 is disposed in the concave portion 12. The other convex part 43 of the board | plate material 4 is obtained in the state fitted to the right side of the oil supply port 31 of the oil path 33 by arrange | positioning toward. 6 is a cross-sectional view taken along the line B-B when the right side of FIG.
As shown in FIG. 6, the end cap 1 </ b> A is fixed to the slider main body 21, and both leg portions are arranged in the vertical direction and used by refueling from an oil supply hole 15 provided at the center of the trunk portion.

  As a result, the lubricant introduced from the oil supply hole 15 passes through the through hole 41 of the plate member 4 and the oil supply port 31 of the block body 3 toward the upper and lower oil passages 33a. 43 is fitted, and while the downwardly directed lubricant is absorbed by the convex portion 43, the lower oil passage 33a is blocked by the convex portion 43, and the lubricant Enters the upper direction change path from the oil supply port 31 toward the upper oil path 33a and from here through the oil path 33b → the oil path 33c → the oil path 33e → the oil path 17.

  After the amount of lubricant absorbed by the convex portion 43 exceeds a certain amount that can be held, the lubricant enters the oil passage 33 below the convex portion 43, and from here the oil passage 33b → the oil passage 33c → the oil passage 33e. → Enter the lower direction change path through the oil path 17. As described above, the flow rate of the lubricant in the oil passage 33a below the convex portion 43 is limited by the presence of the convex portion 43 that is made of felt and has a size that fits in the oil passage 33a in the depth direction and the width direction. The

  That is, according to the slider using the end cap 1A of this embodiment, the lubricant is more likely to be directed to the upper oil passage as compared with the case where the convex portion 43 of the plate member 4 cannot be fitted into the lower oil passage 33a. Become. Moreover, since the block body 3 adheres to the recessed part 12 because the board | plate material 4 made from a thermoplastic elastomer is arrange | positioned between the recessed part 12 and the block body 3 of the trunk | drum 11, it can prevent a lubricating oil leak. .

When the end cap of this embodiment is used as the left end cap 1B in FIG. 1, when the plate member 4 is fitted into the recess 12, the protrusion 43 is formed into the recess 123a on the right side of the oil filler port 15 as shown in FIG. Instead, it fits into the left dent 123b. Accordingly, a cross-sectional view taken along the line BB when the left side of FIG.
In the end cap 1B shown in FIG. 7, the lubricant introduced from the oil supply hole 15 passes through the through hole 41 of the plate member 4 and the oil supply port 31 of the block body 3 in the same manner as the end cap 1A shown in FIG. Although the convex portion 43 is fitted in a portion immediately below the fuel filler port 31, the lower portion of the lubricant is absorbed by the convex portion 43. The oil passage 33a is in a blocked state, and the lubricant flows from the oil supply port 31 toward the upper oil passage 33a and from here through the oil passage 33b → the oil passage 33c → the oil passage 17 to the upper direction change passage. to go into.

After the amount of lubricant absorbed by the convex portion 43 exceeds a certain amount that can be held, the lubricant enters the oil passage 33 below the convex portion 43, and from here the oil passage 33b → the oil passage 33c → the oil passage 33e. → Enter the lower direction change path through the oil path 17. As described above, the flow rate of the lubricant in the oil passage 33a below the convex portion 43 is limited by the presence of the convex portion 43 that is made of felt and has a size that fits in the oil passage 33a in the depth direction and the width direction. The
Therefore, by using the plate member 4 of FIG. 4, it is possible to cope with any of the end caps 1A and 1B arranged in FIG.

An example of a plate material different from FIG. 4 is shown in FIG. FIG. 9 shows a state in which the plate material of FIG. 8 and the block body of FIG. 3 are attached to the end cap body of FIG.
This plate member 4A has the same surface shape as the bottom surface 121 of the recess 12 of the end cap body 10, and through holes 41 and 42 are formed at positions corresponding to the oil supply port 31 and the through hole 32 of the block body 3. . In addition, a rectangular through hole 44 is formed on one of both sides across the central through hole 41. A cork stopper 45 is fitted in the through hole 44. Examples of the material of the plug 45 include elastic bodies such as rubber other than cork.

  A portion of the plug 45 protruding from the plate material 4A is a convex portion 43, and is used by protruding from both surfaces of the plate material 4A. The dimension of the plug 45 in the direction perpendicular to the paper surface of FIG. 8 is a dimension that fits snugly in the oil passage 33a of the block body 3 in the width direction. The dimension L in the thickness direction of the plate material 4A of the plug 45 is smaller than the distance M between the bottom surface of the recess 123a and the bottom surface of the oil passage 33a in a state where the plate material 4A and the block body 3 are attached to the end cap body 10.

When the plate member 4A is attached to the recess 12 of the end cap body 10, the stopper 45 is slid with respect to the through hole 44 so that one end of the stopper 45 reaches the bottom of the recess 123a as shown in FIG. . Thereby, the cross section of the oil passage 33a becomes small by the dimension difference (ML) at the position where the plug 45 is fitted, and the flow rate of the lubricant to the lower oil passage 33a is limited.
If the amount of protrusion toward the oil passage 33a is increased from the state of FIG. 9 without bringing one end of the plug 45 to the bottom of the recess 123a, the flow rate of the lubricant toward the lower oil passage 33a is further reduced. Become. Therefore, according to this plate material 4A, by changing the degree of protrusion of the plug 45 toward the oil passage 33a, the lower oil passage 33a is changed according to the inclination angle in the vertical direction of the wall K shown in FIG. The flow rate of the lubricant directed to the

  Further, instead of the recesses 123a and 123b in FIG. 9, as shown in FIG. 10, a protruding portion from the plate surface of the plug 45 of the plate member 4 </ b> A (the convex portion 43 of the plate member 4) is provided at the same position of the end cap body 10. When the through holes 124a and 124b to be fitted are formed, even after the block body 3 is attached, the end cap 1A is viewed from the opposite side of the slider main body 2 so that the plug 45 (the convex portion 43) is fitted in either. I can see.

  Further, as shown in FIG. 10, when the through holes 124a and 124b are provided instead of the recesses, the plate member 4A is attached to the recess 12 of the end cap body 10 without the stopper 45 attached, and the block body 3 is attached to the recess 12. 1A, the end cap 1A is assembled and fixed to the slider body 2 with bolts that pass through the through holes 16, 41, 32, and then the plug 45 is inserted from the through hole 124a that is aligned with the through hole 44 of the plate 4A. Then, the plug 45 can be fitted into the through hole 44.

After the end cap 1A is assembled, the plug 45 is longer than the distance N between the bottom surface of the oil passage 33a and the end surface of the end cap body 10 in the assembled state. The protrusion amount of the plug 45 to the oil passage 33a can be changed. By doing in this way, even after the end cap 1A is assembled, the amount of the lubricant to be directed to the lower oil passage 33a can be changed.
In addition, when using the fueling port 18 formed in the side surface instead of the fueling port 15 formed in the center of the end cap body in the width direction, the fueling port 15 needs to be closed. In this case, it is preferable to use the plate members 4 and 4 </ b> A that do not have the central through hole 41 communicating with the fuel filler opening 15.

[Second Embodiment]
The end cap of this embodiment can be used as the end caps 1A and 1B of FIG. 1, and the end cap main body 10 shown in FIG. 11, the same block body 3 as the first embodiment shown in FIG. And a plate 40 shown in FIG.
FIG. 11 is a front view of the end cap body 10 of this embodiment (a view showing a surface on the slider body side). FIG. 12A is a front view of the plate member 4. FIG.12 (b) is AA sectional drawing of Fig.12 (a).

As shown in FIG. 11, a recess 12 having a shape into which the block body 3 of FIG. 3 is fitted is formed on the surface of the end cap body 10 on the slider body side. The concave portion 12 mainly includes a portion corresponding to the body portion 11, has a leg portion 12 b extending from the portion toward both the leg portions 13, and further has a positioning portion 12 a of the block body 3.
In the end cap body 10, the outer groove 14 of the direction change path of the rolling element is formed on the surface of the both legs 13 on the slider body side. By fitting the return guide 14a into the outer groove 14, a direction changing path is formed. An oil supply port 15 is formed at the center of the body portion 11. In addition, a through hole 16 through which a bolt for fixing the end cap to the slider body 2 with a bolt is formed in the body portion 11 and the leg portion 13.

In the leg portion 13, an oil passage 17 is formed from the leg portion 12 b of the recessed portion 12 toward the direction changing path. The through hole 16 and the oil filler port 15 of the body part 11 are formed in the recess 12. In addition, oil supply ports 18 are formed on both side surfaces of the body portion 11, and an oil supply passage 18 a at the tip of the oil supply port 18 reaches the side surface 122 of the recess 12, but the oil supply passage 18 a is closed.
As shown in FIG. 12, the plate member 40 has the same surface shape as the bottom surface 121 of the recess 12, and through holes 41 and 42 are formed at positions corresponding to the oil supply port 31 and the through hole 32 of the block body 3. . In this plate member 40, a notch 46 is formed in a leg portion 401 corresponding to the leg portion 12 b of the recess 12. One end of a felt body 47 cut into a shape that fits snugly into the oil passage 33e of the block body 3 is detachably fitted into the notch 46. The portion of the felt body 47 that protrudes from the plate member 40 corresponds to “a convex portion that fits in the oil passage and restricts the flow rate of the lubricant”. The plate member 40 is made of a thermoplastic elastomer.

The end cap 1A of FIG. 1 has a felt body 47 fitted only to one notch 46 of the plate member 40, and this felt body 47 is fitted to the oil passage 33e of the block body 3, as shown in FIG. By arranging the plate member 40 and the block body 3 in the recess 12, the oil passage 17 and the oil passage 33 c on the right side are obtained in a state of being blocked by the felt body 47. 14 is a cross-sectional view taken along the line B-B when the right side of FIG.
As shown in FIG. 14, the end cap 1 </ b> A is fixed to the slider main body 21, and both leg portions are arranged in the vertical direction and used by refueling from an oil supply hole 15 provided at the center of the trunk portion.

Thereby, the lubricant introduced from the oil supply hole 15 passes through the through hole 41 of the plate member 40 and the oil supply port 31 of the block body 3 and goes to the upper and lower oil passages 33a. Since the felt body (convex portion) 47 is fitted to the belt, the lubricant moves up the oil passage 33a below the oil filler port 31 while the downwardly directed lubricant is absorbed by the felt body 47. Thus, the oil passage 33 a on the upper side from the oil supply port 31 → the oil path 33 b → the oil path 33 c → the oil path 33 e → the oil path 17 is entered into the upper direction change path.
After the amount of lubricant absorbed by the felt body 47 exceeds a certain amount that can be held, the lubricant passes through the lower oil passage 17 and enters the lower direction change passage.

Thus, the presence of the felt body 47 limits the flow rate of the lubricant to the oil passage 17 disposed on the lower side.
That is, according to the slider using the end cap 1A of this embodiment, the lubricant is more likely to be directed to the upper oil passage as compared with the case where the felt body 47 of the plate member 40 cannot be fitted into the lower oil passage 33e. . Moreover, since the board | plate material 40 made from a thermoplastic elastomer is arrange | positioned between the recessed part 12 and the block body 3, since the block body 3 closely_contact | adheres to the recessed part 12, lubricating oil leakage can be prevented.

When the end cap of this embodiment is used as the left end cap 1B in FIG. 1, the felt body 47 is not the right notch 46 and the oil passage 33e as shown in FIG. 13, but the left notch 46. And fitted into the oil passage 33e. Accordingly, a cross-sectional view taken along the line BB when the left side of FIG.
In the end cap 1B shown in FIG. 15, the lubricant introduced from the oil supply hole 15 passes through the through hole 41 of the plate member 40 and the oil supply port 31 of the block body 3 in the same way as the end cap 1A shown in FIG. Although the felt body (convex portion) 47 is fitted in the lower oil passage 33e of the block body 3, the lubricant that is directed downward is absorbed by the felt body 47. The agent ascends the oil passage 33a below the oil supply port 31 and passes through the oil passage 33a above the oil supply port 31 → the oil passage 33b → the oil passage 33c → the oil passage 33e → the oil passage 17 to the upper direction change passage. to go into.

After the amount of lubricant absorbed by the felt body 47 exceeds a certain amount that can be held, the lubricant passes through the lower oil passage 17 and enters the lower direction change passage.
Thus, the presence of the felt body 47 limits the flow rate of the lubricant to the oil passage 17 disposed on the lower side.
Therefore, by using the plate member 40 of FIG. 12, it is possible to cope with any of the end caps 1A and 1B arranged in FIG.
In addition, instead of the felt body 47 of this embodiment, what is formed in a dimension that causes a slight gap in the oil passage 33e when attached is used as a “projection that fits in the oil passage and restricts the flow rate of the lubricant”. In this case, the material may be an elastic body such as cork or rubber instead of felt.

It is a figure which shows the use condition of a linear guide apparatus. It is a front view (figure which shows the surface by the side of a slider main body) of an end cap main body (end cap before fitting a block body in a recessed part). It is a perspective view which shows a block body. It is a figure which shows a board | plate material, Comprising: (a) is a front view, (b) is AA sectional drawing of (a).
