Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a manifold that is installed together with a solenoid valve and is applied to supply and exhaust the solenoid valve. More particularly, the present invention relates to a structure for fixing a manifold for solenoid valves for fixing the manifold to a predetermined support.
[0002]
[Prior art]
Conventionally, a solenoid valve is used as one of fluid pressure devices in various industrial fields including semiconductor manufacturing. This type of solenoid valve may be used alone, but in many cases, a plurality of solenoid valves are used in an integrated manner. In this case, a manifold is provided with a plurality of solenoid valves. The manifold is provided for supplying and exhausting each solenoid valve, and has a supply passage and an exhaust passage connected to each solenoid valve. This type of manifold includes a single block type in which multiple solenoid valves are mounted on a single manifold base, or is divided for each solenoid valve. There is an integrated form to do.
[0003]
Here, in order to efficiently position the manifold together with the electromagnetic valve at a predetermined position, and to fix the manifold at the position, a support rail bent in a groove shape (for example, “DIN rail”) is used. According to this support rail, the manifold can be slid along the length direction, and if a predetermined fixing means is used, the manifold can be positioned and fixed at an arbitrary position.
[0004]
15 and 16 show a conventional fixing structure for the manifold. 15 shows an exploded perspective view of the manifold 51 and its fixing structure as viewed from below, and FIG. 16 shows a view of the manifold 51 and its fixing structure as viewed from the front. This fixing structure includes a bracket 52 which is a plate-shaped metal fitting, and a clamp 53 having hooks 53a at both ends. The bracket 52 is fixed to a recess 54 provided on the bottom surface of the manifold 51 with a screw 55. The clamp 53 is temporarily fixed to the bracket 52 with a screw 56 and a nut 57. A pair of screws 58 are attached to both ends of the clamp 53 through the clamp 53. The clamp 53 is attached to the rail 59 so as to hold the support rail 59 with the bracket 52 in between. By tightening the screw 58 in this state, the screw 58 presses the both side projecting portions 59 a of the support rail 59 via the bracket 52. As a result, the clamp 53 rises with respect to the support rail 59, both hooks 53 a are fastened to the overhanging portion 59 a, and the manifold 51 is fixed to the support rail 59.
[0005]
[Problems to be solved by the invention]
However, in the conventional fixing structure, the manifold 51 is fixed to the support rail 59 via the bracket 52 attached to the manifold 51. For this reason, external forces applied to the manifold 51 in all directions are concentrated on the bracket 52, and in order to secure the strength of the bracket 52, it is necessary to enlarge the bracket 52 to some extent. Moreover, the conventional fixing structure includes the bracket 52, the clamp 53, the screws 55 and 56, the nut 57, and another screw 58, and has a relatively large number of parts, and the assembly structure thereof is also complicated.
[0006]
On the other hand, in addition to fixing the manifold 51 to the support rail 59, it may be desired to fix the manifold 51 directly to the mounting surface of another object. However, it is difficult to cope with such a demand with the above-described fixing structure.
[0007]
The present invention has been made in view of the above circumstances, and an object thereof is to enable a manifold to be stably fixed to a support rail with a simple configuration, and to an attachment surface of an object other than the support rail. Another object of the present invention is to provide a solenoid valve manifold fixing structure which can fix the manifold with a simple configuration.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, an invention according to claim 1 is a fixing structure for fixing a manifold installed together with an electromagnetic valve to another object to supply and exhaust the electromagnetic valve. And a support rail having a pair of overhanging portions extending along the length direction on both sides of the width direction, and a bottom surface of the manifold. And a rail groove having a pair of locking projections provided to be able to be locked to both overhanging portions to restrict the vertical movement of the manifold with respect to the support rail, and two locking When the manifold is fixed to the support rail, the rail groove is engaged with the support rail, and the screw hole is inserted into the screw hole. If the manifold is fastened to the support rail by fixing the male screw member and pressing the support rail at the tip of the male screw member, and the manifold is fixed to the mounting surface of an object other than the support rail, place it on the mounting surface. By inserting a second male screw member having a diameter smaller than that of the first male screw member into the screw hole of the manifold, and screwing the male screw member into another screw hole provided in the mounting surface, the manifold is attached to the mounting surface. The purpose is to tighten them.
[0009]
According to the above configuration, the manifold is mounted on the support rail only by engaging the rail groove with the support rail, screwing the first male screw member into the screw hole of the manifold, and pressing the support rail at its tip. It is tightened and fixed. Therefore, in this state, since the support rail engages with the rail groove, the external force applied to the manifold acts in a distributed manner between the rail groove and the support rail, and the first male screw member and the screw hole The action of external force is not concentrated only during the interval. Further, with the exception of the support rail, the basic configuration can be obtained simply by preparing a manifold having rail grooves and screw holes and the first male screw member, and no other complicated parts are required.
[0010]
On the other hand, the screw hole of the manifold is arranged between two locking projections that can be locked to the protruding portion of the support rail, and penetrates perpendicularly to the bottom surface of the manifold without interfering with these locking projections. Provided. Therefore, the manifold is mounted on the mounting surface only by placing the manifold on the mounting surface of an object other than the support rail, inserting the second male screw member into the screw hole, and screwing the male screw member into another screw hole on the mounting surface. Tightened and fixed directly. As a result, the screw hole can also be used, and only the second male screw member is prepared separately, so that the basic configuration is prepared, and no other complicated configuration is required.
[0011]
In order to achieve the above object, according to a second aspect of the present invention, in the configuration of the first aspect of the present invention, there is provided a pressing member that spans the two projecting portions between the support rail and the rail groove. It is intended that the manifold is fastened to the support rail by pressing the pressing member at the tip of the first male screw member that is interposed and screwed into the screw hole.
[0012]
According to the above configuration, in addition to the operation of the first aspect, since the pressing member is stretched over the two overhanging portions of the support rail, the pressing force by the first male screw member is caused by the pressing member in the width direction of the support rail. It is distributed on both sides. Therefore, unlike the case where the support rail is pressed point-intensively with only the male screw member, the manifold is fastened to the support rail in at least two places. Thereby, the pressing force of the male screw member against the support rail is dispersed, and excessive stress concentration in the support rail is eliminated.
[0013]
In order to achieve the above object, the invention described in claim 3 is characterized in that, in the configuration of the invention of claim 1 or claim 2, the first male screw member has a sharp shape.
[0014]
According to said structure, in addition to the effect | action of invention of Claim 1 or Claim 2, since the front-end | tip of a 1st male screw member makes an acute angle, the front-end | tip of a male screw member is supported to a support rail or holding | pressing with comparatively small clamping force. The member can be bitten, and the locking force of the male screw member with respect to the support rail or the pressing member is increased.
[0015]

[First Embodiment]
DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment that embodies a solenoid valve manifold fixing structure according to the present invention will be described below in detail with reference to FIGS.
[0016]
FIG. 1 is a perspective view showing an integrated electromagnetic valve group 1 provided in a predetermined machine facility.

[0017]
Each solenoid valve 2 has a box shape with a small width. Each electromagnetic valve 2 includes a switching valve portion 4 and an actuator portion 5 provided on one side thereof. The switching valve unit 4 incorporates a spool valve for switching a gas flow path as a working fluid. The actuator unit 5 includes a solenoid valve that is electrically driven to drive the spool valve.
[0018]
The manifold base 3 has a block shape, and is installed together with the electromagnetic valves 2 in order to supply and exhaust each electromagnetic valve 2. The manifold base 3 includes an air supply passage, an exhaust passage, and the like connected to each electromagnetic valve 2 therein. The air supply passage and the exhaust passage extend along the longitudinal direction of the manifold base 3. On both end surfaces of the manifold base 3 in the longitudinal direction, one air supply port 7 that is an inlet of the air supply passage and a pair of exhaust ports 6 that are outlets of the exhaust passage are opened. A plurality of output ports 8 connected to the respective electromagnetic valves 2 are provided on one side surface of the manifold base 3. The manifold base 3 is fixed to other objects, that is, a support rail 9, a machine base 10 (see FIG. 8), and the like by a fixing structure described later.
[0019]
Here, the fixing structure of the present embodiment will be described. This fixing structure includes a support rail 9 (for example, “DIN rail”), a pair of first male screw members 11 and nuts 12, and a pressing metal 13 as a pressing member. In this embodiment, two sets of fixing structures having the same configuration are provided at both ends in the longitudinal direction of the manifold base 3 (only one of them is shown in FIG. 1). Therefore, one of them will be described below representatively.
[0020]
FIG. 2 is a partially cutaway view of one end surface of the manifold base 3 in FIG. FIG. 3 is an exploded view of the fixing structure. The support rail 9 is formed in a shape bent in a groove shape in the width direction. The support rail 9 has a pair of overhanging portions 9 a extending along the length direction of the rail 9 on both sides in the width direction.
[0021]
The manifold base 3 has rail grooves 14 corresponding to the support rails 9 on the bottom surface 3a. The rail groove 14 engages the manifold base 3 movably along the support rail 9. The rail groove 14 has a pair of locking projections 14 a provided so as to be locked to both projecting portions 9 a of the support rail 9. These locking protrusions 14 a are for restricting the vertical movement of the manifold base 3 with respect to the support rail 9. Furthermore, the manifold base 3 has a pair of screw holes 15 arranged between the two locking projections 14a. These screw holes 15 penetrate perpendicularly to the bottom surface 3a of the manifold base 3 without interfering with the both locking projections 14a.
[0022]
FIG. 4 shows the first male screw member 11 and the nut 12. The male screw member 11 has a sharp shape. That is, the male screw member 11 has an acute corner 11a at its tip. The male screw member 11 has a male screw 11b on the entire outer periphery thereof. The nut 12 is screwed into the male screw 11b.
[0023]
As shown in FIGS. 1 to 3, the presser fitting 13 is interposed between the support rail 9 and the rail groove 14. 6 and 7 show the front side and the back side of the presser fitting 13, respectively. The pressing metal 13 includes a long plate portion 13a and a projection portion 13b formed in a shape bent at a right angle from one side of the plate portion 13a. As shown in FIG. 6, a pair of narrow grooves 13c are provided on the surface of the plate portion 13a. These narrow grooves 13 c are for engaging the corners 11 a of the first male screw member 11 screwed into the screw holes 15 of the manifold base 3. As shown in FIG. 7, anti-slip 13d made of a plurality of wave streaks is provided at both ends of the bottom surface of the plate portion 13a. The protrusion 13b is provided with a long hole 13e. The presser fitting 13 is attached to the end face of the manifold base 3 via a screw 16 inserted through the elongated hole 13e. By this attachment, the presser fitting 13 is prevented from falling off from the manifold base 3. As shown in FIG. 2, the pressing metal 13 is stretched over the two overhanging portions 9 a of the support rail 9 and pressed by the tip of the first male screw member 11 screwed into the screw hole 15, that is, the corner portion 11 a. It is what is done. At this time, the corner 11a of the male screw member 11 bites into and engages with the narrow groove 13c. Furthermore, the anti-slip 13d of the presser fitting 13 engages with the surface of the overhanging portion 9a.
[0024]
With the above configuration, when the manifold base 3 is fixed to the support rail 9, the rail groove 14 is engaged with the support rail 9, the first male screw member 11 is screwed into each screw hole 15, and the male screw member 11. The support rail 9 is pressed through the presser fitting 13 at the tip of the. Thereby, the manifold base 3 is fastened to the support rail 9.
[0025]
This fixing mode is for efficiently positioning the manifold base 3 together with each electromagnetic valve 2 at a predetermined position, and fixing the manifold base 3 at that position. That is, by loosening the male screw member 11, the manifold base 3 can be slid along the support rail 9, and by tightening the male screw member 1, the manifold base 3 is fixed at an arbitrary position on the support rail 9. be able to.
[0026]
On the other hand, this fixing structure can be applied not only to the support rail 9 but also to fix the manifold base 3 to an object other than the support rail 9. That is, for this purpose, a second male screw member 17 as shown in FIG. 5 is used. The male screw member 17 has a male screw 17a at its distal end and a head 17b at its proximal end. The second male screw member 17 has a smaller diameter than the first male screw member 11. For example, if the size of the first male screw member 11 is “M5”, that of the second male screw member 17 can be “M4”. Thus, since the second male screw member 17 has a smaller diameter than the first male screw member 11, when the male screw member 17 is fitted in the screw hole 15 of the manifold base 3, the male screw member 17 is screwed. Without being screwed into the hole 15, the screw hole 15 is directly penetrated.
[0027]
As shown in FIG. 8, when the manifold base 3 is fixed to an object other than the support rail 9, for example, the mounting surface 10a of the machine base 10 or the like, the manifold base 3 is placed on the mounting surface 10a. . At this time, the pressing metal 13 is removed from the manifold base 3 in advance. Then, the second male screw member 17 is inserted into each screw hole 15 of the manifold base 3 placed on the mounting surface 10a, and the male screw member 17 is screwed into another screw hole 18 provided in advance on the mounting surface 10a. Match. As a result, as shown in FIG. 9, the manifold base 3 is tightened against the mounting surface 10a.
[0028]
As described above, according to the fixing structure of the present embodiment, the manifold base 3 is mounted by engaging the rail groove 14 with the support rail 9, and the first male screw member 11 is inserted into the screw hole 15 of the manifold base 3. Screw together. Then, the manifold base 3 is fastened and fixed to the support rail 9 simply by pressing the support rail 9 with the tip of the male screw member 11.
[0029]
Therefore, in this tightened state, since the support rail 9 engages with the rail groove 14, the external force applied to the manifold base 3 acts in a distributed manner between the rail groove 14 and the support rail 9. The effect of external force is not concentrated only between the male screw member 11 and the screw hole 15. As a result, the manifold base 3 can be stably fixed to the support rail 9.
[0030]
Further, except for the support rail 9, the basic configuration can be obtained simply by preparing the manifold base 3 in which the rail groove 14 and the screw hole 15 are formed, and the first male screw member 11. Does not require any parts. For this reason, the manifold base 3 can be fixed to the support rail 9 with a simple configuration.
[0031]
On the other hand, the screw hole 15 of the manifold base 3 is disposed between the two locking projections 14a of the rail groove 14, and is perpendicular to the bottom surface 3a of the manifold base 3 without interfering with the locking projections 14a. It is provided through. Accordingly, the manifold base 3 is placed on an object other than the support rail 9, for example, the mounting surface 10 a of the machine base 10, and the second male screw member 17 different from the first male screw member 11 is inserted into the screw hole 15 and the male screw member. By simply screwing 17 into another screw hole 18 on the mounting surface 10a, the manifold base 3 is directly brought into contact with the mounting surface 10a to be tightened and fixed. Thereby, the screw hole 15 can be used for fixing to the support rail 9 and the machine base 10. And only by preparing the 2nd male screw member 17 separately, a basic structure is prepared and no other complicated structure is required. As a result, the manifold base 3 can be fixed to the mounting surface 10a of an object other than the support rail 9 with a simple configuration.
[0032]
According to the configuration of this embodiment, the presser fitting 13 is stretched over the two overhang portions 9 a of the support rail 9. For this reason, the pressing force by the first male screw member 11 is distributed to both sides in the width direction of the support rail 9 by the pressing metal 13. Therefore, unlike the case where the support rail 9 is pressed in a point-intensive manner using only the first male screw member 1, the manifold base 3 is fastened to the support rail 9 at both ends of the presser fitting 13, that is, at two locations. . Thereby, the pressing force of the male screw member 11 against the support rail is dispersed, and excessive stress concentration on the support rail 9 is eliminated. In this sense, it is possible to eliminate damage to the support rail 9 that tends to occur due to excessive tightening of the male screw member 11.
[0033]
In this embodiment, the anti-slip 13 d is engaged with the surface of the overhanging portion 9 a of the support rail 9 on the bottom surfaces of both ends of the presser fitting 13. For this reason, the slip between the support rail 9 and the presser fitting 13 can be suppressed, and the tightening force required to fix the manifold base 3 to the support rail 9 to the extent that no lateral displacement occurs is compared. Therefore, the fixing operation of the manifold base 3 can be facilitated.
[0034]
In this embodiment, since the tip of the first male screw member 11 forms an acute angle, the tip of the first male screw member 11 can be bitten into the presser fitting 13 even with a relatively small tightening force. The locking force of the male screw member 11 is increased. In this sense, the tightening force required to fix the manifold base 3 to the support rail 9 can be reduced, and the manifold base 3 can be fixed easily.
[0035]

And the support rail 9 is directly pressed by the tip of the male screw member 11. Thereby, the manifold base 3 is fastened to the support rail 9.
[0039]
On the other hand, in the configuration of this embodiment, in order to fix the manifold base 3 to the mounting surface 10a of the machine base 10 other than the support rail 9, the manifold base 3 placed on the mounting surface 10 as shown in FIG. The second male screw member 17 is inserted into the screw hole 15, and the male screw member 17 is screwed into the screw hole 18 of the mounting surface 10a. Thereby, the manifold base 3 is fastened to the mounting surface 10a.
