[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for connecting structural members for constructing a frame of equipment or the like.

[0002]

2. Description of the Related Art Conventionally, when constructing various structures in which a plurality of extruded aluminum members are connected as a structural member 1, or a pneumatic cylinder, a pneumatic cylinder with a guide, a rodless cylinder with a guide, an electric motor, a linear industrial actuator When constructing a structure used as a structural member together with the linear actuator, or a structure used as a frame of the actuator, the structure member 1 is previously inserted into a groove 2 having a substantially T-shaped cross section formed on a side surface of the structural member 1. A bracket or the like is used for a square nut or a T-shaped nut, and fastening is performed by bolts 6 via the square plates 3 and 4 or the flat plate 5 to join the structural members 1 to each other (FIG. 1). , FIG. 2).

As another means, a bolt 7 having a substantially T-shaped cross section is inserted into the groove 2 having a substantially T-shaped cross section, and a columnar portion having a conical concave portion is inserted into a hole in the end face of the mating structural member 1. Insert and insert a horizontal hole 〆 screw 8 on the side of the structural member 1
By tightening the set screw, the bolt 7 is pulled and the structural members 1 are joined together (see FIG. 3).

[0004] Further, when the assembled structure is to be replaced once, in addition to cutting the structural member 1, a necessary number of nuts are inserted or horizontal holes are machined to reconstruct the structure.

[0005]

However, in assembling and rearranging according to the prior art, nuts and the like are previously attached to the structural member 1 which is closed to join both end surfaces to the side surface of the other structural member 1. If there is a change in reinforcement or expansion of the structure constructed by connecting the new structural members 1 or connecting another member, disassemble unnecessary parts as well. In addition, nuts must be inserted, which is inconvenient.

In the case of connection using a T-shaped bolt 7, when the structural member 1 is cut to a required length in order to reconstruct the structure, the end face of the joint portion is oriented with respect to the longitudinal direction. If it is not vertical, there is a disadvantage that the horizontal and vertical accuracy of the structure cannot be obtained at the time of connection. Furthermore, in addition to cutting, the side hole processing must be performed on the side surface of the structural member 1, and the operation becomes complicated.

FIG. 4 is a perspective view of a structural member and a connecting member according to an embodiment of the present invention, FIG. 5 is a partial cross-sectional view showing a state where the connecting member is connected to the structural member, and FIG. It is a perspective view showing the state where structural members were connected to each other.

In FIG. 4, a connection block (hereinafter, referred to as a block) 12 which is connected to a cut end face cut substantially perpendicularly to the longitudinal direction of the structural member 10 and functions as a connection means is a die-cast, precision-cast, Is formed by a method such as vacuum die casting, vacuum casting, lost wax method, extrusion, drawing, metal powder injection molding, or ceramics injection molding, and a substantially cylindrical projection 14 is formed at a substantially central portion of the joint surface of the structural member 10. Is provided. The projecting portion 14 is defined at the axial center of one of the structural members 10 to be attached, and is fitted with a dimensional tolerance of fitting into the through hole 16 functioning as a fluid passage. Thus, even if the cut surface of the structural member 10 is not cut perpendicularly to the longitudinal direction, the projecting portion 14 of the block 12 is defined vertically to the contact surface, and the through hole 16 of the structural member 10 is formed. Is formed parallel to the longitudinal direction, so that the contact surface of the block 12 is straightened in the longitudinal direction of the structural member 10. In addition, the said structural member 10

It is formed by a method such as extrusion, drawing, or large casting of a silicon-magnesium alloy.

The block 12 is provided with claw portions (connecting portions) 18 which are arranged to face each other so as to surround the projecting portions 14.
Is provided. A substantially circular hole 20 is defined in the claw portion 18. The claw portion 18 is provided on the
Is inserted into the groove portion 22 having a substantially T-shaped cross section, and the set screw (first fixing member) 24 is tightened through the hole portion 20 so that the set screw 24 is formed in the groove portion 22 defined in the structural member 10. The connection can be made surely by digging into the deep portion 26 and elastically or plastically deforming, preferably by plastically deforming. Further, the tip portion 25 of the claw portion 18 spreads outward in a direction opposite to the direction in which the set screw 24 is tightened, so that the claw portion 18 bites into the inclined surface between the groove portion 22 and the deep portion 26, and the block 12 Can be more reliably obtained (see FIG. 5). At this time, the protrusions 14 are inserted into the through holes 16 in order to prevent the block 12 from shifting due to the difference in the amount of tightening of the set screw 24, and further, each claw portion provided to face the end face of the block 12. 18 is inserted from the longitudinal direction of the groove portion 22 of the structural member 10 so that the positioning can be performed reliably.

Block 1 attached to structural member 10
2, a bolt member (engaging member) 28 having a substantially T-shaped cross section is inserted together with a spring 30, and a head 3 of the bolt member 28 is inserted.
2 is inserted from the longitudinal side surface of the counterpart structural member 10 to be connected, and is rotated by about 90 degrees, so that the retaining action can be exhibited. The bolt member 28 securely and easily connects the block 12 to the structural member 10 without rotating or wobbling due to the elastic force of the spring 30 by tightening the set screw 34 (second fixing member). (See FIG. 6). When these fixing members are removed from the connected counterpart structural member 10, when the set screw 34 is loosened, the elastic force of the spring 30 acts in a direction to separate the bolt member 28 from the counterpart structural member 10, The structural member 10 can be easily removed and rebuilt.

Here, as shown in FIG. 7, a case where a part of the structural member 10 in which the head 32 of the bolt member 28 is connected to the block 12 undergoes plastic deformation or, preferably, elastic deformation will be described. . Bolt member 28 is block 1
When inserted into the second side, the back surface portion 36 of the head portion 32 of the bolt member 28 comes into contact with the flat portion 38 of the groove portion 22 having a substantially T-shaped cross section. A step portion 40 is defined on a surface of the flat portion 38 that contacts the opposite side of the block 12, and the bolt member 28 is formed.
When the back surface portion 36 presses the flat portion 38 of the groove portion 22, the corner portion 42 is deformed toward the block 12 and the
(See FIG. 7b).

Next, a connecting mechanism for connecting the structural members 10 according to the second embodiment will be described with reference to FIGS.

The bolt member 28 and the spring 30 are inserted into the through hole 48 of the rectangular block 46 attached to the cut end surface of the structural member 10 with four hexagonal tapping screws 44, and the set screw 34 is tightened. The one structural member 10 and the other structural member 10 can be easily connected. In addition, the spring 30 inserts and holds the bolt member 28 against the resilience of the spring 30 at the time of connection, thereby preventing the position of the groove of the bolt member 28 from rotating and shifting or wobbling. After the connection, when the set screw 34 is loosened again, the bolt member 28 acts to easily separate the one structural member 10 from the other structural member 10.

At the four corners of the rectangular block 46, there are defined holes 50 into which the hexagonal tapping screws 44 are fitted, and through holes 16 defined at substantially the center of the end surface of the structural member 10. When used as various fluid passages such as compressed air,
In the end face of the structural member 10, a gasket groove, which is difficult to perform additional processing, is previously formed on the rectangular block 46 side, and sealing is performed. The leakage of various fluids inside the structural member 10 is prevented without causing a problem such as a dimensional change at the time of connection of the structural member 10, and the fluid can enter and exit from the opening of the through hole 16 on the end face of the structural member 10. Further, a gasket groove and a seal member may be provided between the structural member 10, the rectangular block 46 and the structural member 10 further connected, and a fluid passage may be provided between the plurality of connected structural members 10.

Next, a description will be given of a case where a plurality of structural members 10 are connected to each other to assemble a structure, and then a reinforcing member or another structural member 10 is attached.

As shown in FIG. 10 and FIG. 11, a bolt member 52 is inserted into a groove 22 having a substantially T-shaped cross section formed on the side surface of the structural member 10. In this case, the long side portion 56 of the head 54 of the bolt member 52 is inserted along the longitudinal direction of the groove 22, and then the head 54 of the bolt member 52 is stopped by rotating the head 54 by about 90 degrees, The bolt member 52 can be fixed at a desired position of the groove 22.
After the bolt member 52 is fixed in the groove 22 on the side surface of the structural member 10 in this manner, as shown in FIG. 11, the reinforcing members 58, 60, 62, 6 having shapes corresponding to the respective connection portions are provided.
4 can be tightened by the nut member 66. Therefore, by using the bolt member 52 and the reinforcing members 58 to 64, the strength connection of the constructed structure is reinforced,
The rigidity as a whole is increased, and in addition to preventing a decrease in accuracy when used with an actuator or the like connected, by connecting another structural member 10 or the like, the equipment can be easily expanded.

Next, FIGS. 12 to 16 show side views of end surfaces of other various structural members.

FIGS. 12 to 14 show structural members 66, 68, and 70 suitable for use in a portion where a strong load is applied to a structure assembled into a desired shape. FIGS. Structural members 72, 74 are shown which are lighter by defining a space. The structural members 66 to 74 are formed of a light metal material such as an aluminum alloy, a magnesium alloy, and an aluminum-silicon-magnesium alloy, and are subjected to a surface treatment such as alumite, hard alumite, and titanium coating, so that their mechanical strength is reduced. It is possible to improve and reduce the scratches on the surface that is attached when attaching or detaching various members.
Further, coloring by painting, preferably coloring by colored alumite treatment, may be used for identification of facilities and insulation.

Becomes

Next, a connecting mechanism of structural members according to a third embodiment of the present invention is shown in FIGS. In the following embodiments, the same components as those of the third embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

In the figure, when connecting the structural members 80a and 80b to each other, a connection block 82 is attached to the cutting end surface of one of the structural members 80a. The connection block 82 has a projection 86 which is inserted into the through hole 16 substantially at the center of the cutting end surface of the structural member 80a and is provided with a plurality of slits 84a to 84f. Claws 90 a to 90 f are provided on the outer peripheral surface of the tip end portion 88 of the projection 86 divided into sheets, and connection protrusions 92 are provided at four corners near the projection 86. On the other hand, a hole 98 for inserting a bolt member 96 having a tapered portion 94 and having a substantially T-shaped cross section is defined on the surface opposite to the protrusion 86. On the upper surface of the connection block 82, a female screw portion 10 to be fitted with a set screw 100 having a male screw portion engraved on the outer peripheral surface is provided.
2, the tip of the set screw 100 is formed in a tapered shape, and engages with a tapered concave portion 104 defined in the bolt member 96.

Therefore, the connecting projections 92 of the connection block 82 are inserted into the holes defined at the four corners of the structural member 80a, and the projections 86 are inserted into the through holes 16, respectively. 82 is attached to the cutting end surface of the structural member 80a. Next, by loosely fitting the bolt member 96 into the hole 98 of the connection block 82, the tapered portion 94 of the bolt member 96 comes into contact with the inner peripheral surface of the distal end 88 of the projection 86 (FIG. 18 ( a)). The bolt member 96
Of the other structural member 80b
Are engaged. Subsequently, by fitting the set screw 100 to the female screw portion 102 of the connection block 82,
As shown in FIG. 18B, the tip of the set screw 100 presses the inclined surface of the concave portion 104 of the bolt member 96 to displace the bolt member 96 in the direction of arrow A. When the bolt member 96 is displaced in the direction of arrow A, the head 106 of the bolt member 96 pulls one structural member 80b in the axial direction of the other structural member 80a to connect the two. At this time, the tapered portion 94 at the distal end of the bolt member 96 acts to push the distal end 88 of the projection 86 toward the outer peripheral side and pushes it open, so that it is engraved on the outer peripheral surface of the distal end 88 of the projection 86. The claw portions 90a to 90f bite into the inner peripheral surface of the through-hole 16 and serve to prevent removal. In this way, one structural member 80a and the other structural member 80b can be easily connected.

Next, a connecting mechanism of structural members according to a fourth embodiment of the present invention is shown in FIGS.

The fourth embodiment is different from the third embodiment in that the connecting block 82 is partially cut away instead of providing the claw portions 90a to 90f on the outer peripheral surface of the distal end portion 88 of the projection 86 of the connection block 82. The C-ring 110 to the groove 11 at the tip.
2a to 112f, and a sharp claw 114 is provided on the outer peripheral surface of the C-ring 110 at a predetermined interval. Thus, the C-ring 11 having the claw portion 114
0 is attached to the distal end portion 88 of the projection 86, so that the structural member 80a and the structural member 80b are once connected, and when they are separated from each other, the bolt member 96 is detached and elastically deformed to expand. There is an advantage that the diameter of the C-ring 110 is reduced and returned to its original state, and the structural members 80a and 80b can be easily separated from each other. In addition,
Other configurations and operations at the time of connection are the same as those of the above-described embodiment, and thus detailed description thereof will be omitted.

Next, a connecting mechanism of structural members according to a fifth embodiment of the present invention is shown in FIGS.

The structural members 116a, 116 according to the present embodiment

The rotation of the holding member 124 causes the first bevel gear 126 integrated with the lower part of the holding member 124 to rotate, and the second bevel gear 138 meshing with the first bevel gear 126 to rotate. Due to the rotation of the second bevel gear 138, the bolt member 136 is screwed in the direction of arrow A to pull one structural member 116b in the axial direction of the other structural member 116a. Thus, the structural members 116a,
116b can be easily connected to each other, and the set screw 100b can be simply used as in the third and fourth embodiments.
Of the first and second bevel gears 12 in comparison with the fastening by the contact between the tip of the bolt member 96 and the inclined surface of the concave portion 104 of the bolt member 96.
Through the interpositions 6 and 138, the structural members 116a and 116b can be reliably connected to each other with a weak tightening torque. In addition, there is an advantage that loosening of the connecting portion due to vibration or impact is reduced.
