Description

[Technical field]

[0001] The present invention relates to a stopper device that restricts the movement of a slider that moves on a guide rail. [Background technology]

[0002] There is a linear guide device equipped with a slider that moves on a guide rail. A stopper device that restricts the movement of the slider that moves on the guide rail is attached to the guide rail of such a linear guide device. This makes it possible to prevent the slider from overrunning and from falling off the guide rail during transportation, etc. Such a stopper device for a linear guide device is described in, for example, Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 5-12749 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, the sizes of the guide rails in the linear guide device vary. Therefore, it is necessary to prepare a stopper device according to the size of these guide rails. Therefore, an object of the present invention is to provide a stopper device that can be adjusted according to the size of the guide rail. [Means for solving the problem]

[0005] One aspect of the present invention is a stopper device that is attached to a guide rail and restricts movement of a slider that moves on the guide rail, comprising a first member having a first upper member covering an upper surface of the guide rail and a first lower member covering a first side surface, which is one of both side surfaces of the guide rail, and connected to the first upper member; a second member having a second upper member covering an upper surface of the guide rail and a second lower member covering a second side surface, which is the other of both side surfaces of the guide rail, and connected to the second upper member; and an upper fixing device that fixes the first upper member and the second upper member to each other when the first upper member and the second upper member are stacked so that the position of the second upper member relative to the first upper member in the width direction of the guide rail can be changed, and the stopper device is attached to the guide rail by sandwiching the first side surface and the second side surface between the first lower member and the second lower member.

[0006] This stopper device can change the position of the second upper member relative to the first upper member in the width direction of the guide rail by using the upper fixing device. In other words, the distance between the first lower member and the second lower member can be adjusted according to the width of the guide rail. In this way, this stopper device can be adjusted according to the size of the guide rail.

[0007] In the above stopper device, the upper fixing device is a screw, the first upper member and the second upper member are stacked on top of each other so that the first upper member is positioned between the second upper member and the upper surface, the second upper member is provided with an upper long hole through which the threaded portion of the screw is passed, and the first upper member is provided with an upper tapped hole into which the tip of the threaded portion of the screw engages, and the upper long hole may extend along the width direction of the guide rail.

[0008] In this case, when the screw is loosened, the second upper member can be moved relative to the first upper member due to the upper long hole provided in the second upper member. In this way, in the stopper device, the distance between the first lower member and the second lower member can be adjusted according to the width of the guide rail by loosening the screw. Also, in the stopper device, the movement of the second upper member relative to the first upper member can be restricted by tightening the screw, and both sides of the guide rail can be sandwiched between the first lower member and the second lower member. In this way, in the stopper device, adjustment according to the size of the guide rail can be easily performed by operating the screw.

[0009] The above-mentioned stopper device further includes an extension member arranged on top of the first lower member so that the first lower member is positioned between the first side surface and the extension member, and a side fixing device that fixes the first lower member and the extension member to each other so that the position of the extension member relative to the first lower member in the vertical direction of the guide rail can be changed when the first lower member and the extension member are overlapped, and the extension member has a lower end extension portion that extends downwardly beyond the first lower member, and the lower end extension portion may be provided with a convex portion that protrudes toward the first side surface and abuts against the first side surface.

[0010] In this case, the position of the extension member relative to the first lower member in the height direction of the guide rail can be changed by the side fixing device. In other words, the extension member can be raised and lowered according to the height of the guide rail. In addition, a protrusion that abuts against the first side surface of the guide rail is provided on the lower end extension of the extension member. This allows the stopper device to clamp both sides of the guide rail not only by the first and second lower members but also by the protrusions whose height positions are adjusted. In this way, this stopper device allows adjustment according to the width and height of the guide rail.

[0011] Another aspect of the present invention is a stopper device that is attached to a guide rail and restricts movement of a slider that moves on the guide rail, the stopper device having an upper member covering an upper surface of the guide rail, a first lower member covering a first side surface that is one of both side surfaces of the guide rail and connected to one end of the upper member, and a second lower member covering a second side surface that is the other of both side surfaces of the guide rail and connected to the other end of the upper member, the stopper main body being attached to the guide rail by sandwiching the first and second side surfaces between the first and second lower members, an extension member arranged overlapping the first lower member, and a side fixing device that fixes the first lower member and the extension member to each other so that, when the first lower member and the extension member are overlapped, the position of the extension member relative to the first lower member in the vertical direction of the guide rail can be changed.

[0012] This stopper device can change the height position of the extension member relative to the first lower member in the height direction of the guide rail by using the side fixing device. In other words, the extension member can be raised or lowered according to the height of the guide rail. In this way, this stopper device can be adjusted according to the size of the guide rail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In each drawing, the same or corresponding elements are denoted by the same reference numerals, and duplicated explanations will be omitted.

[0016] As shown in FIG. 1, the linear guide device A includes a stopper device 1, a guide rail 2, and a slider 3. The guide rail 2 is a long member. The guide rail 2 is fixed to the base of, for example, a machine tool, a measuring instrument, or the like, by means of a mounting bolt or the like. In the following, the surface of the guide rail 2 that abuts against the base is referred to as the lower surface 2d, and the opposite surface is referred to as the upper surface 2a. In addition, the side of the upper surface 2a with respect to the lower surface 2d is referred to as the "upper" and the side of the lower surface 2d with respect to the upper surface 2a is referred to as the "lower".

[0017] A rolling groove 2e extending along the extension direction of the guide rail 2 is provided on both side surfaces (left side surface 2b, right side surface 2c) of the guide rail 2. In the following, one of the two side surfaces of the guide rail 2 will be referred to as the left side surface (first side surface) 2b, and the other side surface will be referred to as the right side surface (second side surface) 2c. Also, the left side surface 2b side relative to the right side surface 2c side will be referred to as the "left", and the right side surface 2c side relative to the left side surface 2b side will be referred to as the "right".

[0018] In this embodiment, two rolling grooves 2e are provided on the left side surface 2b, and two rolling grooves 2e are provided on the right side surface 2c. The slider 3 is installed on the guide rail 2 so as to straddle the guide rail 2. The slider 3 has a rolling groove at a portion facing the rolling groove 2e. A plurality of rolling elements (balls or rollers) are rollably disposed between the rolling groove 2e of the guide rail 2 and the rolling groove of the slider 3. When the slider 3 moves on the guide rail 2, these rolling elements circulate between the rolling groove 2e of the guide rail 2 and the rolling groove of the slider 3, and in a circulation path provided in the slider 3.

[0019] A driven body, such as a tool rest in the case of a machine tool, is attached to the slider 3. The slider 3 moves along the guide rail 2 to move the driven body.

[0020] The stopper device 1 is substantially U-shaped. The stopper device 1 is attached to the guide rail 2 by sandwiching a left side surface 2b and a right side surface 2c of the guide rail 2. The stopper device 1 can be attached to any position in the extension direction of the guide rail 2. The stopper device 1 restricts the movement of the slider 3 that moves on the guide rail 2 by abutting against the slider 3.

[0021] As shown in Fig. 2 and Fig. 3(a) to Fig. 3(c), the stopper device 1 includes a first member 10, a second member 20, a first extension member (extension member) 30, a second extension member (extension member) 40, a first screw (upper fixing device, screw) 51, a second screw (side fixing device) 52, a third screw (side fixing device) 53, a first washer 61, a second washer 62, and a third washer 63. In Fig. 2, the first screw 51 to the third screw 53 and the first washer 61 to the third washer 63 are removed. In Fig. 3(a) to Fig. 3(c), the first screw 51 to the third screw 53 and the first washer 61 to the third washer 63 are omitted.

[0022] The first member 10 is substantially L-shaped. The first member 10 is disposed so as to face the upper surface 2a and the left side surface 2b of the guide rail 2. The first member 10 has a first upper member 11 and a first lower member 12. The first upper member 11 covers the upper surface 2a of the guide rail 2. The first lower member 12 covers the left side surface 2b of the guide rail 2. The first lower member 12 is also connected to the left end portion of the first upper member 11. In this manner, the first lower member 12 extends downward from the left end portion of the first upper member 11.

[0023] The second member 20 has a substantially L-shape. The second member 20 is disposed so as to face the upper surface 2a and the right side surface 2c of the guide rail 2. The second member 20 has a second upper member 21 and a second lower member 22. The second upper member 21 covers the upper surface 2a of the guide rail 2. In this embodiment, the second upper member 21 faces the upper surface 2a of the guide rail 2 via the first upper member 11 of the first member 10. The second lower member 22 covers the right side surface 2c of the guide rail 2. In addition, the second lower member 22 is connected to the right end portion of the second upper member 21. In this manner, the second lower member 22 extends downward from the right end portion of the second upper member 21.

[0024] The first upper member 11 and the second upper member 21 are stacked on top of each other such that the first upper member 11 is located between the upper surface 2a of the guide rail 2 and the second upper member 21. In other words, the lower surface of the first upper member 11 abuts against the upper surface 2a of the guide rail 2. The lower surface of the second upper member 21 abuts against the upper surface of the first upper member 11.

[0025] In this way, the first upper member 11 of the first member 10 and the second upper member 21 of the second member 20 constitute an upper member that covers the upper surface 2a of the guide rail 2. The first lower member 12 is connected to the left end of the upper member constituted by the first upper member 11 and the second upper member 21. The second lower member 22 is connected to the right end of the upper member constituted by the first upper member 11 and the second upper member 21. The upper member constituted by the first upper member 11 and the second upper member 21, the first lower member 12, and the second lower member 22 constitute a stopper main body portion of the stopper device 1.

[0026] The first extension member 30 is disposed so as to overlap the first lower member 12 such that the first lower member 12 of the first member 10 is positioned between the first extension member 30 and the left side surface 2b of the guide rail 2. In other words, the first lower member 12 is positioned between the left side surface 2b of the guide rail 2 and the first extension member 30.

[0027] The first extension member 30 has a first lower end extension portion (lower end extension portion) 31 that extends downward below the lower end portion of the first lower member 12. The first lower end extension portion 31 is provided with a first protrusion (protrusion portion) 32 that protrudes toward the left side surface 2b of the guide rail 2 and abuts against the left side surface 2b.

[0028] The second extension member 40 is disposed so as to overlap the second lower member 22 of the second member 20 such that the second lower member 22 is positioned between the second extension member 40 and the right side surface 2c of the guide rail 2. In other words, the second lower member 22 is positioned between the right side surface 2c of the guide rail 2 and the second extension member 40.

[0029] The second extension member 40 has a second lower end extension portion (lower end extension portion) 41 that extends downward below the lower end portion of the second lower member 22. The second lower end extension portion 41 is provided with a second protrusion portion (protrusion portion) 42 that protrudes toward the right side surface 2c of the guide rail 2 and abuts against the right side surface 2c.

[0030] The first screw 51 fixes the first upper member 11 and the second upper member 21 to each other in a state in which the first upper member 11 of the first member 10 and the second upper member 21 of the second member 20 are stacked on top of each other. The first screw 51 also fixes the first upper member 11 and the second upper member 21 to each other so that the position of the second upper member 21 relative to the first upper member 11 is variable in the width direction (left-right direction) of the guide rail 2. In other words, the first screw 51 fixes the first member 10 and the second member 20 to each other so that the distance between the first lower member 12 of the first member 10 and the second lower member 22 of the second member 20 is variable.

[0031] Here, the second upper member 21 of the second member 20 is provided with an upper elongated hole 21a, which is an elongated hole through which the threaded portion of the first screw 51 is passed. The upper elongated hole 21a extends along the width direction (left-right direction) of the guide rail 2. In addition, the upper surface of the second upper member 21 is provided with an upper countersunk elongated hole 21b, which is a countersunk elongated hole into which the first washer 61 can be dropped. The upper countersunk elongated hole 21b extends along the width direction (left-right direction) of the guide rail 2.

[0032] On the other hand, the first upper member 11 of the first member 10 is provided with an upper tapped hole 11a that is a tapped hole into which the tip of the threaded portion of the first screw 51 engages. In this embodiment, a plurality of upper tapped holes 11a (three in this embodiment) are provided along the width direction of the guide rail 2.

[0033] The threaded portion of the first screw 51 is passed through the first washer 61 and the upper elongated hole 21a with the first washer 61 dropped into the upper countersunk elongated hole 21b of the second upper member 21. The tip of the threaded portion of the first screw 51 is engaged with the upper tapped hole 11a of the first upper member 11. In this manner, the first member 10 and the second member 20 are fixed to each other by the first screw 51. The threaded portion of the first screw 51 has a length such that the tip of the threaded portion does not protrude from the lower surface of the first upper member 11.

[0034] In addition, the first upper member 11 of the first member 10 is provided with a plurality of upper tapped holes 11a. This allows the stopper device 1 to change the position of the upper tapped hole 11a to which the first screw 51 is engaged. In addition, the second upper member 21 of the second member 20 is provided with an upper elongated hole 21a extending along the left-right direction. As a result, the first screw 51 can fix the first member 10 and the second member 20 to each other while making the position of the second upper member 21 relative to the first upper member 11 variable in the width direction (left-right direction) of the guide rail 2. That is, in the stopper device 1, the distance between the first lower member 12 of the first member 10 and the second lower member 22 of the second member 20 is variable.

[0035] The second screw 52 fixes the first lower member 12 and the first extension member 30 of the first member 10 to each other in a state in which the first lower member 12 and the first extension member 30 are stacked on top of each other. The second screw 52 also fixes the first lower member 12 and the first extension member 30 to each other while making the position of the first extension member 30 relative to the first lower member 12 variable in the vertical direction of the guide rail 2. In other words, the second screw 52 fixes the first extension member 30 to the first lower member 12 while making the height position (vertical position) of the first extension member 30 variable.

[0036] Here, the first extension member 30 is provided with a first oblong hole 30a, which is an oblong hole through which the threaded portion of the second screw 52 is passed. The first oblong hole 30a extends along the height direction (up-down direction) of the guide rail 2. Also, a first countersunk oblong hole 30b, which is a countersunk oblong hole into which the second washer 62 can be dropped, is provided on a surface of the first extension member 30 (the surface opposite to the surface that abuts against the first lower member 12). The first countersunk oblong hole 30b extends along the height direction (up-down direction) of the guide rail 2.

[0037] On the other hand, the first lower member 12 of the first member 10 is provided with a first tapped hole 12a which is a tapped hole into which the tip of the threaded portion of the second screw 52 engages. In this embodiment, a plurality of first tapped holes 12a (two in this example) are provided along the height direction of the guide rail 2.

[0038] The threaded portion of the second screw 52 is passed through the second washer 62 and the first elongated hole 30a with the second washer 62 dropped into the first countersunk elongated hole 30b of the first extension member 30. The tip of the threaded portion of the second screw 52 is engaged with the first tapped hole 12a of the first lower member 12. In this manner, the first member 10 and the first extension member 30 are fixed to each other by the second screw 52. The threaded portion of the second screw 52 has a length such that the tip of the threaded portion does not protrude from the surface of the first lower member 12 on the guide rail 2 side.

[0039] The first lower member 12 of the first member 10 is provided with a plurality of first tapped holes 12a. This allows the stopper device 1 to change the position of the first tapped holes 12a with which the second screws 52 are engaged. The first extension member 30 is provided with a first elongated hole 30a extending along the vertical direction. This allows the second screws 52 to fix the first member 10 and the first extension member 30 to each other while allowing the position of the first extension member 30 relative to the first upper member 11 to be variable in the height direction (vertical direction) of the guide rail 2. That is, in the stopper device 1, the height position of the first extension member 30 (first protrusion 32) is variable.

[0040] The third screw 53 fixes the second lower member 22 and the second extension member 40 of the second member 20 to each other in a state in which the second lower member 22 and the second extension member 40 are stacked on top of each other. The third screw 53 also fixes the second lower member 22 and the second extension member 40 to each other while making the position of the second extension member 40 relative to the second lower member 22 variable in the vertical direction of the guide rail 2. In other words, the third screw 53 fixes the second extension member 40 to the second lower member 22 while making the height position (vertical position) of the second extension member 40 variable.

[0041] Here, the second extension member 40 is provided with a second oblong hole 40a, which is an oblong hole through which the threaded portion of the third screw 53 is passed. The second oblong hole 40a extends along the height direction (up-down direction) of the guide rail 2. In addition, a second countersunk oblong hole 40b, which is a countersunk oblong hole into which the third washer 63 can be dropped, is provided on a surface of the second extension member 40 (the surface opposite to the surface that abuts against the second lower member 22). The second countersunk oblong hole 40b extends along the height direction (up-down direction) of the guide rail 2.

[0042] On the other hand, the second lower member 22 of the second member 20 is provided with a second tapped hole 22a which is a tapped hole into which the tip of the threaded portion of the third screw 53 engages. In this embodiment, a plurality of second tapped holes 22a (two in this example) are provided along the height direction of the guide rail 2.

[0043] The threaded portion of the third screw 53 is passed through the third washer 63 and the second elongated hole 40a with the third washer 63 dropped into the second countersunk elongated hole 40b of the second extension member 40. The tip of the threaded portion of the third screw 53 is engaged with the second tapped hole 22a of the second lower member 22. In this manner, the second member 20 and the second extension member 40 are fixed to each other by the third screw 53. The threaded portion of the third screw 53 has a length such that the tip of the threaded portion does not protrude from the surface of the second lower member 22 on the guide rail 2 side.

[0044] The second lower member 22 of the second member 20 is provided with a plurality of second tapped holes 22a. This allows the stopper device 1 to change the position of the second tapped hole 22a with which the third screw 53 is engaged. The second extension member 40 is provided with a second elongated hole 40a extending along the vertical direction. This allows the third screw 53 to fix the second member 20 and the second extension member 40 to each other while making the position of the second extension member 40 relative to the second lower member 22 variable in the height direction (vertical direction) of the guide rail 2. That is, in the stopper device 1, the height position of the second extension member 40 (second protrusion 42) is variable.

[0045] Next, a method of mounting the stopper device 1 will be described. As described above, the stopper device 1 can adjust the distance between the first lower member 12 of the first member 10 and the second lower member 22 of the second member 20 by the first screw 51. The stopper device 1 is mounted to the guide rail 2 by sandwiching both side surfaces (left side surface 2b, right side surface 2c) of the guide rail 2 between the first lower member 12 and the second lower member 22. At that time, the first convex portion 32 of the first extension member 30 abuts against the left side surface 2b of the guide rail 2. Also, the second convex portion 42 of the second extension member 40 abuts against the right side surface 2c of the guide rail 2. As a result, the stopper device 1 can also sandwich both side surfaces of the guide rail 2 by the first convex portion 32 and the second convex portion 42.

[0046] Also, the stopper device 1 can be attached to, for example, the guide rail 2A shown in Fig. 4. The guide rail 2A is different in size from the guide rail 2 shown in Fig. 2. Even in this case, the stopper device 1 can sandwich both side surfaces of the guide rail 2A because the distance between the first lower member 12 of the first member 10 and the second lower member 22 of the second member 20 is variable. Also, the stopper device 1 can adjust the height positions of the first convex portion 32 and the second convex portion 42 according to the height of the guide rail 2A, and the guide rail 2 can be sandwiched by the first convex portion 32 and the second convex portion 42 whose height positions have been adjusted.

[0047] As described above, the stopper device 1 can change the position of the second upper member 21 relative to the first upper member 11 in the width direction of the guide rail 2 by the first screw 51. That is, the distance between the first lower member 12 and the second lower member 22 can be adjusted according to the width of the guide rail 2. In addition, the stopper device 1 can change the height positions of the first extension member 30 and the second extension member 40 in the height direction of the guide rail 2 by the second screw 52 and the third screw 53. That is, the first extension member 30 and the second extension member 40 can be raised and lowered according to the height of the guide rail 2. In this way, the stopper device 1 can be adjusted according to the size of the guide rail 2. This allows the stopper device 1 to be used for guide rails of various sizes.

[0048] Moreover, in the stopper device 1, the guide rail 2 can be more firmly clamped by using the first screw 51. This makes it possible to prevent the stopper device 1 from shifting position even if the slider 3 hits it. Furthermore, the stopper device 1 can be easily attached to and detached from the guide rail 2 by using the first screw 51.

[0049] The second upper member 21 of the second member 20, through which the threaded portion of the first screw 51 is passed, is provided with an upper long hole 21a. When the first screw 51 is loosened, the second upper member 21 can be moved relative to the first upper member 11. In this way, in the stopper device 1, the distance between the first lower member 12 and the second lower member 22 can be adjusted according to the width of the guide rail 2 by loosening the first screw 51. In addition, in the stopper device 1, the movement of the second upper member 21 relative to the first upper member 11 can be restricted by tightening the first screw 51, and both sides of the guide rail 2 can be sandwiched between the first lower member 12 and the second lower member 22. In this way, in the stopper device 1, adjustment according to the size of the guide rail 2 can be easily performed by operating the first screw 51. Furthermore, in the stopper device 1, adjustment according to the size of the guide rail 2 can be easily performed by changing the position of the upper tapped hole 11a into which the tip of the threaded portion of the first screw 51 is engaged.

[0050] The stopper device 1 can change the position of the first extension member 30 relative to the first lower member 12 in the height direction of the guide rail 2 by the second screw 52. The stopper device 1 can change the position of the second extension member 40 relative to the second lower member 22 in the height direction of the guide rail 2 by the third screw 53. That is, the first extension member 30 (first convex portion 32) and the second extension member 40 (second convex portion 42) can be raised and lowered according to the height of the guide rail 2. In addition, the first extension member 30 and the second extension member 40 are provided with the first convex portion 32 and the second convex portion 42, respectively. As a result, the stopper device 1 can sandwich both side surfaces of the guide rail 2 not only by the first lower member 12 and the second lower member 22, but also by the first convex portion 32 and the second convex portion 42 whose height positions have been adjusted. In this way, the stopper device 1 can be adjusted according to the width and height of the guide rail.

[0051] In the stopper device 1, similarly to the case of the first screw 51, the height positions of the first extension member 30 and the second extension member 40 can be easily adjusted in accordance with the size of the guide rail 2 by operating the second screw 52 and the third screw 53. Also, in the stopper device 1, adjustment in accordance with the size (height) of the guide rail 2 can be easily performed by changing the position of the first tapped hole 12a into which the tip of the threaded portion of the second screw 52 engages and the position of the second tapped hole 22a into which the tip of the threaded portion of the third screw 53 engages.

[0052] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, in the above embodiment, the second upper member 21 is provided with an upper countersunk slot 21b into which the first washer 61 is dropped. Similarly, the first extension member 30 and the second extension member 40 are also provided with a first countersunk slot 30b and a second countersunk slot 40b, respectively. It is not essential that such a countersunk slot is provided into which the washer is dropped. Specifically, as in the stopper device 1A shown in FIG. 5 and FIG. 6(a) to FIG. 6(c), the countersunk slot may not be provided. Here, the stopper device 1A includes a second upper member 21A that does not include a countersunk slot, instead of the second upper member 21 in the embodiment. Similarly, the stopper device 1A includes a first extension member 30A and a second extension member 40A that do not include a countersunk slot, instead of the first extension member 30 and the second extension member 40 in the embodiment. Even in this case, the stopper device 1A can achieve the same effects as the stopper device 1 in the above-described embodiment.

[0053] The stopper device 1 is adjustable in the width direction and the height direction of the guide rail 2. However, the present invention is not limited to this, and the stopper device 1 may be adjustable in only one of the width direction and the height direction of the guide rail 2.

[0054] The stopper device 1 may be configured to fix the first upper member 11 and the second upper member 21 with a fastener other than the first screw 51. Similarly, the stopper device 1 may be configured to fix the first extension member 30 and the second extension member 40 to the first lower member 12 and the second lower member 22, respectively, with a fastener other than the second screw 52 and the third screw 53.
