Description

The present invention relates to a method for fixing a mechanical structure and the fixed structure thereof, and in particular, a mechanical structure different from the mechanical structure (for example, UPS (Uninterruptible Power Supply) or PCS (Power Conditioning System)). A mechanical structure suitable for bolting a supply device), a control panel for an industrial drive, a device body such as a computer server, and a stand on which it is placed) in a narrow part (a place where it is difficult to reach and workability is poor). The fixing method and the fixing structure thereof.

Seismic resistance is required for the housing for electronic devices (for example, the device body of a computer server), which is assumed to be one of the devices for bolting a mechanical structure and another mechanical structure in a narrow portion, and IEC. The design conforms to the seismic standards stipulated by (International Electrotechnical Commission) and JIS (Japanese Industrial Standards).

Normally, in housing design, it is necessary to minimize the weight with strength as a constraint, but in general, increasing the strength of the housing also increases the weight, and the increase in weight increases manufacturing, transportation, installation costs, etc. However, since the product price is high, it is important to secure the strength of the housing without increasing the weight as much as possible in order to keep the cost burden on the consumer low.

When installing equipment such as electronic devices, it is common to fix the gantry on a sturdy floor and bolt the equipment body (housing) onto it. The bolt fastening position is several tens of millimeters inside from the side surface of the housing from the viewpoint of workability, and the outer end of the housing where the bolts are not fastened is lifted during an earthquake (see FIG. 9C), and the amount of horizontal deformation is large. It is a factor to increase.

Patent Document 1 describes a technique for reducing the lifting of the housing during such an earthquake. In Patent Document 1, a hook hole is provided in the gantry, and a flange-shaped protrusion provided on the bottom surface of the device body (housing) is passed through the hook hole to fix the device body (housing) and the end of the gantry. The technology to be used is described.

Japanese Unexamined Patent Publication No. 2012-147523

The above-mentioned Patent Document 1 describes a technique for reducing the lifting of the device main body (housing) due to an earthquake or the like, but a flange-shaped protrusion provided on the bottom surface of the device main body (housing) is provided on the gantry. Since it is a mechanism for hooking through a hook hole, there is a problem that the fastening force is weaker than that for bolt fastening.

The present invention has been made in view of the above points, and an object of the present invention is to prevent the equipment structure from being lifted from the gantry due to an earthquake or the like, even if the equipment structure and the gantry are bolted in a narrow portion. It is an object of the present invention to provide a method for fixing a mechanical structure and a fixing structure thereof, which can suppress and obtain a fastening structure having high seismic resistance.

The method for fixing a mechanical structure of the present invention is a method for fixing a mechanical structure in which the main body of the mechanical structure and the pedestal supporting the main body of the mechanical structure are fastened and fixed with bolts in order to achieve the above object. The bottom surface of the device body and the top surface of the gantry form a rectangular shape, and each of the rectangular corners faces from the inside to the outside or from the inside to the outside in parallel with one side surface of the rectangle. A guide hole for guiding to the narrow portion is formed, and the device main body and the gantry are temporarily fastened with the bolt at the initial position through the guide hole, and from this state, the bolt is pulled by the bolt extrusion support component. By extruding from the inside to the outside through the guide hole, the device body and the gantry are finally fastened with the bolts by being guided from the initial position to the final position of the narrow portion.

Further, the fixing structure of the mechanical structure of the present invention is a fixing structure of the mechanical structure in which the device main body of the mechanical structure and the gantry supporting the device main body are fastened and fixed with bolts in order to achieve the above object. Each of the device main body and the gantry has a guide hole in which the bolt for guiding to the narrow portion between the device main body and the gantry can be slid, and the bolt has the guide hole. Is provided with a bolt extrusion support component that slides the bolt to the narrow portion from the initial position, and by applying a force to the bolt extrusion support component, the bolt is slid through the guide hole to slide the guide hole from the initial position to the narrow portion. It is characterized in that the device main body and the gantry are finally fastened with the bolts at the final position of the narrow portion by being guided by extruding to.

According to the present invention, even if the equipment structure and the gantry are bolted in a narrow portion, it is possible to suppress the lifting of the equipment structure from the gantry due to an earthquake or the like and obtain a fastening structure having high earthquake resistance. ..

Hereinafter, a method for fixing the mechanical structure of the present invention and the fixing structure thereof will be described based on the illustrated examples. In each figure, the same reference numerals are used for the same components.

FIG. 1 shows a control panel 1 of an industrial drive and a pedestal 2 for supporting the control panel 1 of an industrial drive as an equipment main body which is an example of a method for fixing a mechanical structure of the present invention and an electronic device to which the fixing structure is applied. is there.

In the figure, the control panel 1 of the industrial drive is composed of a power converter 3 and a control circuit unit 4, which are devices housed in the housing 1A, and is supported by a gantry 2. Reference numeral 5 denotes a door for accessing the inside of the housing 1A.

2 (a) and 2 (b) show a schematic configuration of this embodiment, and are in a state where the bolts are temporarily fastened at the initial positions.

In the figure, 6 is a bolt for fastening the control panel 1 of the industrial drive and the gantry 2, 7 is a nut used as a pair with the bolt 6, and 8a and 8b are attached to and contact with the bolt 6 and the nut 7. A washer (washer) for reducing the surface pressure of the surface, 9 is a bolt extrusion support part, and 10 is an oval guide hole for guiding the bolt 6 provided on both the gantry 2 and the control panel 1 of the industrial drive to the side surface. is there.

That is, in this embodiment, an oval guide hole 10 in which a bolt 6 for guiding to a narrow portion between the control panel 1 and the gantry 2 of the industrial drive can slide into each of the control panel 1 and the gantry 2 of the industrial drive. The bolt 6 is provided with a bolt extrusion support component 9 for pushing the bolt 6 from the initial position to a narrow portion by sliding the guide hole 10.

From the viewpoint of increasing the strength of the housing 1A and reducing the deformation during an earthquake, it is desirable to bolt it closer to the side surface, but bolting near the side surface is a factor that deteriorates workability, so it is general purpose. The distance from the side is specified for the gantry and the like. In FIG. 2A, the distance indicated by the arrow “D” corresponds to this.

In the present embodiment, first, with this specified position as the initial position, the gantry 2, the control panel 1 of the industrial drive, and the bolt extrusion support component 9 are put together and first fastened with bolts 6. However, as will be described in detail later, this embodiment is characterized in that the bolt 6 in the temporarily fastened state is moved, and the tightening force of the bolt 6 at the initial position is appropriate in order to enable the movement of the bolt 6. (The tightening force is such that the bolt 6 can be moved at the initial position and the required fastening can be maintained at the final position).

Then, the bolt extrusion support component 9 is pushed out along the guide hole 10 that guides the bolt 6 to the side surface (force is applied to the bolt extrusion support component 9). It is possible to use a general manual hammer for extruding the bolt extrusion support component 9, but it is better to use, for example, an automatic hammer that can intermittently apply an impact excitation force in a short cycle. ..

3 (a) and 3 (b) are examples of a state in which the bolt 6 is moved from the initial position (temporary fastening position) along the guide hole 10 and finally fastened in a narrow portion by the means of this embodiment. is there.

As shown in the figure, the fastening portion with the bolt 6 is fixed by the means described above (by applying a force to the bolt extrusion support component 9) until the bolt extrusion support component 9 finally abuts on the control panel 1 of the industrial drive. , The bolt 6 is moved by sliding the bolt 6 from the inner end to the outer end of the oval guide hole 10 and pushing it from the initial position (temporary fastening position) to the narrow portion) to move the bolt 6 to the narrow portion. At the final position, the control panel 1 of the industrial drive and the gantry 2 are finally fastened with bolts 6.

More specifically, the bottom surface of the control panel 1 of the industrial drive and the top surface of the gantry 2 form a rectangular shape, and an oval guide hole 10 is formed in each of the rectangular corners from the inside to the outside. Is formed, and the bolt 6 pushes the oval guide hole 10 from the inner end to the outer end by the bolt extrusion support component 7, so that the oval guide hole 10 is guided from the initial position (temporary fastening position) to the final position of the narrow portion. The control panel 1 of the industrial drive and the gantry 2 are finally fastened with bolts 6.

As a result, the control panel 1 of the industrial drive and the outer end portion of the gantry 2 can be brought into close contact with each other more firmly, and the lifting of the control panel 1 of the industrial drive from the gantry 2 is reduced. Therefore, it is possible to suppress the lifting of the control panel 1 of the industrial drive from the gantry 2 due to an earthquake or the like, and to obtain a fastening structure having high earthquake resistance.

FIG. 4 shows an example of connecting the control circuit unit 4 which is a device and the gantry 2 by a conventional means, and FIG. 5 shows an example of the structure of the conventional gantry 2.

In the figure, 4 is a control circuit unit, 2 is a gantry, 4a is a screw hole for fastening a bolt provided at a specified position on the bottom surface of the control circuit unit 4, and 2a is a screw provided on the upper surface of the gantry 2. Holes 11 indicate the upper surface of the gantry 2.

In FIG. 4, the control circuit unit 4 and the gantry 2 are represented by a surface having no thickness for convenience of explanation, but in reality, FIGS. 2 (a), 2 (b), 3 (a), and FIGS. As shown in 3 (b), it has a plate thickness.

As shown in FIGS. 4 and 5, conventionally, the screw holes 4a for fastening bolts provided at the specified positions on the bottom surface of the control circuit unit 4 and the screw holes 2a provided on the upper surface of the gantry 2 are pedestals. When the control circuit unit 4 was placed on the control circuit unit 2, the screw holes 4a and the center positions of the screw holes 2a were opened so as to match, and the bottom surface of the control circuit unit 4 and the upper surface of the gantry 2 were opened. I put my hand in the work hole (not shown) and tightened the bolts.

On the other hand, in this embodiment, as shown in FIG. 6, the bottom surface portion of the control circuit unit 4 and the top surface portion of the gantry 2 form a rectangular shape, and each rectangular corner portion faces from the inside to the outside. The oval guide holes 10a and 10b are formed, and the bolt pushes the oval guide holes 10a and 10b from the inner end to the outer end by the bolt extrusion support component, so that the oval guide holes 10a and 10b are formed from the initial position (temporary fastening position). The control circuit unit 4 and the gantry 2 are finally fastened with bolts by being guided to the final position of the narrow portion.

7 (a) and 7 (b) are examples of the structure of the gantry 2 of this embodiment, and 11 shows the upper surface of the gantry 2.

In FIG. 7A, an oval guide hole 10b is formed in the direction of the corner where the two side surfaces of the upper surface portion of the rectangular pedestal 2 intersect (from the inside to the outside at the rectangular corner portion). An example of moving the bolt toward the corner where the two side surfaces intersect is shown, but in consideration of the direction in which the housing sways and the like, as shown in FIG. 7B, the upper surface of the rectangular frame 2 An oval guide hole 10b may be provided so as to move toward one side surface (from the inside to the outside in parallel with one rectangular side surface).

8 (a) and 8 (b) are views showing a state in which the control circuit unit 4 and the gantry 2 are finally fastened by the means of the present embodiment described above.

As described above, FIG. 8A is formed at the corners of the rectangular shape of the bottom surface of the control circuit unit 4 and the upper surface of the gantry 2 from the inside to the outside. The oval guide hole 10 is moved to the corner by pushing the bolt from the inner end to the outer end by the bolt extrusion support component, and guides it to the final position of the narrow part to guide the control circuit part 4 and the gantry 2. The state after the final fastening with the bolt (reference numeral 12 is the state) is shown, and FIG. 8B is an enlarged view thereof. The detailed shapes of the bolt extrusion support parts and bolts are omitted.

The reasons why it is better to move the bolt fastening portion between the device body and the gantry to the vicinity of the side surface of the device body in this way are explained in FIGS. 9 (a), 9 (b), 9 (c) and 9 (d). Will be described using.

9 (a), 9 (b), 9 (c), and 9 (d) are schematic views showing the degree of deformation of the housing of the device main body in this embodiment and the conventional means. FIG. 9A shows a bolted state by the conventional means, and FIG. 9B shows a bolted state according to the present embodiment.

In FIG. 9A, 15 is a device main body premised on bolt fastening by the conventional means, 16 represents the mass of the devices housed inside the device, and 17 is a bolt fastening position by the conventional means. Then, this is assumed to be vibrated in the horizontal direction, and 18 represents the housing shape deformed by the vibration.

Further, in FIG. 9B, 19 represents a device main body premised on the bolt fastening means according to this embodiment, 20 represents a bolt fastening position according to this embodiment, and 21 represents a housing shape deformed by vibration.

9 (c) and 9 (d) show the deformation with emphasis so that the deformed portion of the housing of the device main body can be easily understood.

In the bolt fastening by the conventional means shown in FIG. 9 (c), the bolt fastening position 17 by the conventional means in FIG. 9 (c) is deformed by raising the outer end of the housing which is not bolted, so that the maximum on the upper surface of the device is reached. The displacement (A in FIG. 9C) becomes large.

On the other hand, in the present embodiment shown in FIG. 9D, since the bolt fastening portion is brought close to the side surface of the device main body, the outer end portion of the housing does not rise and the bolt fastening position 20 does not deform. It can be seen that the maximum displacement of the upper surface of the device (B in FIG. 9D) due to bolt fastening in this embodiment is smaller than that in the conventional means shown in FIG. 9C.

By the way, there is a possibility that the bolt extrusion support parts may loosen due to seismic motion or vibration generated by the equipment itself, and the bolt may return from the final position to the initial position direction.

FIG. 10 shows an example of the second embodiment of the present invention in which the bolt extrusion support component 9 is prevented from loosening and the bolt 6 is prevented from returning to the initial position direction from the final position.

That is, as shown in FIG. 10, in this embodiment, the control panel 1 of the industrial drive, the gantry 2, and the bolt extrusion support component 9 are finally fastened with the bolt 6 at the final position of the narrow portion, and the bolt extrusion support is supported. A second bolt 22 is provided to prevent the component 9 from moving in the direction opposite to the extrusion direction in the guide hole 10.

By adopting such a configuration of this embodiment, it is possible to obtain the same effect as that of the first embodiment, and of course, the second bolt 22 prevents the bolt extrusion support component 9 from loosening and the bolt 6 is in the final position. It is possible to prevent the product from returning to the initial position.

FIG. 11 shows another example as the third embodiment of the present invention, which prevents the bolt extrusion support component 9 from loosening and prevents the bolt 6 from returning to the initial position direction from the final position.

That is, as shown in FIG. 11, in this embodiment, the bolt 6 is finally fastened with the bolt 6 in the state where the control panel 1 of the industrial drive, the gantry 2 and the bolt extrusion support component 9 are finally fastened at the final position of the narrow portion. A second bolt 23 is provided to fix the bolt extrusion support component 9 by pushing it through a fixing plate 24 having a screw groove until it moves to the end of the guide hole 10.

By adopting such a configuration of this embodiment, it is possible to obtain the same effect as that of the first embodiment, and of course, the second bolt 23 prevents the bolt extrusion support component 9 from loosening and the bolt 6 is in the final position. It is possible to prevent the product from returning to the initial position. Note that FIG. 11 also has a mechanism for pushing out the bolt extrusion support component 9.

FIG. 12 shows, as a fourth embodiment of the present invention, an example of means for fastening the bolt 6 more robustly when moving the bolt 6 in the guide hole 10.

That is, as shown in FIG. 12, in this embodiment, the thickness of the portion to be fastened to the bottom surface of the control panel 1 of the industrial drive at the initial position of the bolt 6 on the upper surface of the gantry 2 is set to the final thickness of the bolt 6. The thickness of the part to be finally fastened at the position is made thinner (the thickness of the part to be fastened to the upper surface of the gantry 2 at the initial position of the bolt 6 on the bottom surface of the control panel 1 of the industrial drive is bolted. It may be thinner than the plate thickness of the portion to be finally fastened at the final position of 6).

By adopting such a configuration of this embodiment, it is possible to obtain the same effect as that of the first embodiment, and of course, by making the plate thickness of the initial fastening position thinner than that of the final fastening position, the same effect as the wedge can be obtained. Is obtained, and the fastening force of the bolt 6 after movement can be increased.

13 (a), 13 (b), and 13 (c) show conventional means for suppressing the lifting of the control panel 1 of the industrial drive from the gantry 2.

In FIG. 13A, an auxiliary plate 25 straddling the boundary between the control panel 1 and the gantry 2 of the industrial drive is provided on the outer surface of the device, and the industrial drive is provided with bolts 6 and nuts 7 via the auxiliary plate 25. The control panel 1 and the gantry 2 are joined.

In FIG. 13B, flange-shaped protrusions 1a and 2b are provided on the outer surface of the apparatus, and the flange-shaped protrusions 1a and 2b are connected to the industrial drive control panel 1 and the gantry 2 with bolts 6 and nuts 7. It is to be joined.

In FIG. 13C, a vise-shaped fixture 26 is used to join the control panel 1 of the industrial drive and the gantry 2 at the end of the device.

The conventional means shown in FIGS. 13 (a), 13 (b) and 13 (c) described above are all considered to be effective in suppressing the lifting of the control panel 1 of the industrial drive. When installing a server device for information equipment, the upper surface of the gantry is often below the floor surface of the raised floor, and the means shown in FIGS. 13 (a) and 13 (b) are of workability. Difficult to apply from a point of view. Further, in FIG. 13C, since the work can be performed inside the device, there is no problem of interfering with the floor surface, but there is a concern that the installation cost will increase.
