In these rodless cylinders with guides, hitherto, the combination of the cylinder diameter of the rodless cylinder and the guide rail has been fixed in advance. However, due to the diversification of user needs, there has been a demand to easily change the combination, but if the combination is decided in advance as described above, the change is not easy. In addition, in the combination fixed as described above, the base for fixing the guide rail is also
Since it was a fixed combination corresponding to the cylinder diameter and the corresponding guide rail, if there are multiple cylinder diameters, prepare the same number of guide rails and bases as the number of cylinder diameters corresponding to them. In particular, since the base is often extruded from an aluminum alloy, the same number of molds is required for many types of bases, which is complicated from the viewpoint of management. However, there is also a problem that it is difficult to reduce the cost due to the mold cost. The object of the present invention is to

Of course, each of the left and right connecting plates 20 and 21 may be provided with a supply / discharge port corresponding to the left and right cylinder chambers S1 and S2.

The slide table 18 includes the side wall 1 in the width direction.
It is connected to the guide 15 at a position closer to b. The slide table 18 overhangs in the width direction from the connecting portion with the guide 15 to above the external moving body 44 of the rodless cylinder unit 30, and does not vertically overlap with the cylinder barrel 31. In the portion overlapping the external moving body 44, the leg 70 is provided at a position sandwiching the axial front and rear of the external moving body 44.
Is projecting toward the base. The external moving body 44 is sandwiched between a pair of front and rear legs 70, and a rubber damper (cushioning member) 71 is interposed between the end plate 45 of the external moving body 44 and the legs 70. The movement of 44 is transmitted to the slide table 18. A stopper 72 having a longitudinal length shorter than that of the slide table 18 is fixed to the lower surface of the slide table 18 between the guide 15 and the leg 70. Stopper 72
The axial end surfaces of the slide table 18 are contact surfaces 73, 73 with a shock absorber, which will be described later. As is clear from the drawing, the end surfaces 18a of the slide table 18 are more contact surface 73, 73.
Has entered inside in the longitudinal direction.

Next, at the inner position of the connection plates 20 and 21, as shown in FIG. 3, a concave groove (fitting groove) 76 is provided at the end of the guide rail 10 at the base of the stop member mounting holder 75. Is fitted, and its tip end 77 is projected in the width direction toward the rodless cylinder unit 30,
Using the T-slot 4, a T-slot nut 78 and a tightening bolt 79 screwed into the T-slot nut 78 are fixed so as to be movable in the axial direction. The left and right surfaces of the groove 76 are substantially in close contact with the left and right peripheral surfaces (vertical surfaces) 10a, 10a of the guide rail 10 (the width direction surface portions of the guide rail that are not related to the guide groove 14). The tip of the holder 75 for mounting the stop member is divided into two parts, and the screw portion 81 formed on the outer periphery of the shock absorber 80 is screwed into the shock absorber 80 so that the shock absorber is displaced laterally from the guide rail 10. The position of the shock absorber 80 itself is axially adjustable with respect to the holder 75, and the shock absorber 80 is fixed to the holder 75 with a fixing screw 82 at a predetermined axial position. The shock absorber 80 is provided on the stopper 7 of the slide table 18.
2 is axially opposed to 2, and is located axially inward from the axially outer end surfaces of the connection plates 20 and 21. The shock absorber 80 may not be used depending on the usage of the linear actuator. Reference numeral 85 is a mounting hole that vertically penetrates the connection plates 20 and 21, and reference numeral 86 is a mounting groove for an accessory member such as a switch provided in the side wall 1b.

As described above, the guide rail 10 has the base 1
Connection plates 20 and 21 extending laterally to the base are fixed to the end portion (here, the end surface) of the base 1, and the base bottom wall 1a and the rod are connected to the side of the base 1 between the connection plates 20 and 21. Since the slits 32 are arranged laterally toward the guide rails 10 by stacking them in the height direction with the pressureless cylinder unit 30, since the guide rails 10 are integrated with the base 1, the rigidity is maintained high, so that the connecting plate 20, Even when it is attached to a mechanical device by using the attachment holes 85 of 21, the guide of the slide table 18 is smoothly maintained and its usage is diversified as compared with the case where there is no base at all. 32 is sideways,
Since the external moving body 44 arranged on the outside of the slit 32 is laterally oriented, the rodless cylinder with a guide having a small thickness can be provided, and the external moving body 44 can also be applied to a place where a vertical gap is narrow.

When the pressurized fluid (compressed air) is supplied or discharged from the supply / discharge ports 23a and 23b, the piston 40 moves from one stroke end to the other stroke end, whereby the external moving body 44 moves. Is moved so that the slide table 18 moves straight in a state of being guided by the guide rail 10. Slide table 18
Comes to the stroke end, the abutting surface 73 of the stopper 72 abuts the shock absorber 80, and the slide table 1
8. The stop shock is softened and stopped. Figure 1
In the shock absorber 80 on the right side of FIG. 1, an axial force acts on the base portion of the holder 75 at the time of collision, and a clockwise moment is applied to the base portion of the holder 75 in the horizontal direction by the axial force. Since the groove 76 is fitted in the left and right surfaces 10a, 10a of the long guide rail 10 which is firmly fixed to the base 1, its moment is substantially passed through the left and right surfaces 10a, 10b of the guide rail 10. The stop member mounting holder 75, which can be received by the entire base 1 and is easily loosened only by tightening only the tightening screw 79, can be held at a predetermined position without loosening for a long period of time, and the left and right vertical sides of the guide rail 10 that receive a moment can be held. The surfaces 10a, 10a are
Since the surface is unrelated to the guide groove 14, the guide of the guide 15 is not adversely affected even with such a configuration.

At the stroke end, the projection of the shock absorber 80 goes under the slide table 18 and abuts against the abutment surface 73, so that the abutment surface is conventionally located on the end surface of the slide table 18. If the strokes are the same, this configuration can shorten the overall length of the rodless cylinder with a guide by the length overlapped with the slide table 18 at the time of collision, and the rodless cylinder with a guide can be made compact. With the same total length, the stroke can be lengthened according to this configuration.

Considering the case where the shock absorber 80 is removed from the above structure for convenience of use, the rodless cylinder unit 30 has a stroke end between stroke ends in which its piston 40 abuts on both end fitting members 33. It will move back and forth. Then, at the stroke end, the piston thrust force always acts on the end fitting member 33, and the end fitting member 33 receives a force outward in the axial direction. End fitting member 3
3 is only fitted into the cylinder hole 34,
In particular, on the side where the push screw 62 is provided, although there is friction holding by the fixing screw 54 that holds the outer seal band 51, there is no holding force enough to overcome the thrust, and the seal bands 50 and 51 are pulled. Attempting to move outwardly in the axial direction by the distance t, but the thrust force is
Since it is received by the connection plate 21 via the push screw 62, it is possible to prevent excessive tension from being generated in the seal bands 50 and 51 as a result, and to prevent deformation and damage of the seal bands 50 and 51. obtain. Further, even if the shock absorber 80 is not removed, by supplying the pressurized fluid, the corresponding end fitting member 33 receives the thrust force in the axial direction by the fluid pressure.
Similarly to the case of removing the band, the thrust of the band can be received by the connecting plate 21 by the action of the push screw 62.
It is possible to prevent the generation of tension due to the thrust at 0,51.

Next, in the assembly system of the present application, for example, as shown in FIG. 6, the rodless cylinder unit has a plurality of driving types (slit tube type or magnet type) and a plurality of cylinder diameters (here, 10). type)
It is divided into. For the base and the guide rail, one having a cylinder diameter of 25 mm (type 5) is used as a common one for all types.
Therefore, in this embodiment, the base 1 and the guide rail 10 are different from those of the 10 types of rodless cylinder units.
Only one type needs to be prepared. Therefore, even if there are many types of rodless cylinder units, it is not necessary to manage many types of the base 1 and the guide rail 10, and especially in the base 1, the die cost for the extruded profile is greatly reduced, and The cost will be reduced. Then, a drawing is prepared for the one type of base 1 and the guide rail 10 with the longitudinal direction as a variable. Then, for each of these types of rodless cylinder units, a drawing with the dimension in the longitudinal direction as a variable is prepared, and each rodless cylinder unit for connecting the rodless cylinder unit and the base of the common section is prepared. Drawings of the connection plates 20 and 21 corresponding to the types are prepared. Furthermore, by using a common base, different parts (slide table, etc.) are prepared corresponding to the type of each rodless cylinder unit.

When a user requests a rodless cylinder with a guide (type 6) using a magnet type rodless cylinder unit 30A having a cylinder diameter of 25 mm, the length in the longitudinal direction which is the stroke requested by the user is set. Applied to the drawings of base 1 and guide rail 10,
Thereby, the base 1 and the guide rail 10 are created. Further, a magnet type rodless cylinder unit 30A having a cylinder diameter of 25 mm is manufactured with a stroke requested by the user. Magnet type rodless cylinder unit 30
As shown in FIG. 7, A is obtained by closing both ends of a thin-walled cylinder tube 90 made of a non-magnetic material with end fitting members 33A, so that the inner moving body 92 and the tube 90 inside the tube 90 are closed.
The outer moving body 93 fitted so as to make sliding contact with the outer side
And are magnetically coupled to each other by inner and outer magnet rows 96 and 97 incorporated in the respective moving bodies 92 and 93. Then, in order to connect the rodless cylinder unit 30A and the base 1, the screw hole diameter and position of the screw 22 are the same (FIG. 8), but the end fitting member 33A of the rodless cylinder unit 30A.
Has a fitting hole 60A (the diameter of which is different from that of the slit type), into which the fitting portion 33Ac of FIG.
The connection plates 20A and 21A are prepared. Then, the guide rail 10 is fixed to the base 1, the connection plates 20A and 21A are fixed to the front and rear ends of the base 1, and the magnet type rodless cylinder unit 30A is arranged between the pair of connection plates 20A and 21A. , External moving body 93
Is sandwiched between the legs 70A of the slide table (for 25 mm of the magnet type rodless cylinder unit) 18A to assemble the magnet cylinder with guide (type 6) having the magnet type rodless cylinder unit.

0 (type 9). From these drawings, the sizes of the connection plates 21B and 21C and the slide table 1
It can be seen that the sizes of 8B and 18C are different depending on each cylinder diameter. Similarly, other types of rodless cylinders with guides are also manufactured. In the present application, a rodless cylinder group with guides is composed of 10 types of rodless cylinders with guides, all of which have a common cross-sectional shape of the base and guide rails. is there. Even between the magnet type and the slit type, those having a close cylinder diameter, for example, a magnet type cylinder diameter of 20 mm (type 4) and a slit type of 25.
The size of the slide table can be made the same among those having a size of 5 mm (type 5) or the like, which can further reduce the kinds of parts.

In the present application, 10 types of rodless cylinder units have been described as a system in which only one type of base and guide rails are used. However, a plurality of types having different cylinder types and different drive types ( For example, the product group may be made into a series by preparing a common base and guide rail only for rod type cylinder units of magnet type and slit type: type 3 to 6) having cylinder diameters of 20 mm and 25 mm. Although the rodless cylinder has been described as a slit type or a magnet type so far, other drive types such as a band and a pulley, a roller and a pulley, a flexible tube and a roller are also available. A rodless cylinder can also be applied.
