Description

電気品収容用筐体及びその製作方法Housing for storing electrical products and manufacturing method thereof
　本発明は、電気品収容用筐体及びその製作方法に関し、特に、鉄道車両における電気品の収容用の筐体に適用して好適なものである。 The present invention relates to a housing for storing electrical products and a method for manufacturing the same, and is particularly suitable for application to a housing for storing electrical products in a railway vehicle.
　一般的に、鉄道車両の床下には、駆動用電動機に供給する電力を制御する車両駆動用制御装置、空調などの車上電気設備へ供給する電力を制御する補助電源装置及び保守用の端末を収納した保安装置、などの鉄道車両用電気品を収容した筐体が設置される。 Generally, under the floor of a railway vehicle, there are a vehicle drive control device that controls the power supplied to the drive motor, an auxiliary power supply device that controls the power supplied to the on-board electrical equipment such as an air conditioner, and a maintenance terminal. A housing that houses electrical equipment for railway vehicles such as a stored security device is installed.
　この鉄道車両用電気品を収容する筐体は、薄板を接合することにより製作されるが、接合方法によっては、筐体の品位（品質）を低下させ、場合によっては接合箇所が収容する鉄道車両用電気品やその電気配線を破損してしまうことがある。 The housing that accommodates the electrical equipment for rail vehicles is manufactured by joining thin plates, but depending on the joining method, the quality (quality) of the housing may be reduced, and in some cases, the joining location accommodates the rail vehicle. Electrical equipment and its electrical wiring may be damaged.
　このような状況のもと、近年では筐体に工夫をすることで、車両静止時の静的応力又は車両走行時の振動による動的応力に対しての筐体の強度を保ちつつ筐体の品位を向上させる研究開発が広く行われ、実用化されている。 Under these circumstances, by devising the housing in recent years, the strength of the housing is maintained while maintaining the strength of the housing against static stress when the vehicle is stationary or dynamic stress caused by vibration when the vehicle is running. Research and development to improve the quality is widely conducted and put into practical use.
　この種の電気品収容用筐体の１つとして、例えば特許文献１には、薄板同士を接合する際に位置決めし、断続的な隅肉溶接により接合し、接合箇所に対応するようにビードを内部に収容する切り欠き部を形成する発明が開示されている。 As one example of this type of electrical equipment housing, in Patent Document 1, for example, positioning is performed when thin plates are joined together, joining is performed by intermittent fillet welding, and a bead is provided so as to correspond to the joining location. An invention for forming a notch to be housed inside is disclosed.
特開２０１３－６６９００号公報JP 2013-66900 A
　ところで、一般的には余計な接合箇所を設けて筐体の強度の低下を招かないように、筐体はその外壁を一枚の薄板とし、一枚の薄板を板金加工により曲げることで形成され、内壁は断続的な隅肉溶接により外壁と複数点で固定する。 By the way, in general, the housing is formed by bending one thin plate by sheet metal processing so that the outer wall is a single thin plate so as not to reduce the strength of the housing by providing an extra joint. The inner wall is fixed at multiple points with the outer wall by intermittent fillet welding.
　このような筐体構造においては、筐体が大きい場合に筐体天板及び筐体底板も大きくなり、一枚の薄板を一般的な板金加工により曲げる際に、曲げ型及び加工部品が重くなる。このため、作業に人手が必要となり筐体製作のための作業工数が増える問題又はクレーンなどの設備が必要となる問題がある。また高価な大型の打ち抜きプレス機及び曲げ加工機が必要となる問題もある。さらに標準的な大きさの板材では筐体を構成することができず、特殊寸法の大きな板材を用意する必要があるといった問題や特殊寸法の板材の保管場所の確保といった問題もある。 In such a case structure, when the case is large, the case top plate and case bottom plate also become large, and when bending a single thin plate by general sheet metal processing, the bending mold and processed parts become heavy. . For this reason, there is a problem that manpower is required for the work and the number of work man-hours for manufacturing the casing is increased, or a facility such as a crane is required. There is also a problem that an expensive large punching press and bending machine are required. Furthermore, there is a problem that a case cannot be configured with a standard size plate material, and it is necessary to prepare a plate material having a large special dimension, and there is a problem of securing a storage place for the special size plate material.
　また、歪み変形を抑制する溶接方法としてスポット溶接が知られているが、筐体天板及び筐体底板に補強部材及び電気品固定台座を接合する際、作業工数が増えてしまう問題又は高価な設備が必要となる問題がある。安価な定置式スポット溶接機を使用する場合は、特殊寸法の大きな板材を加工する際に、加工部品が重くなり、人手が必要となり作業工数が増える又はクレーンなどの設備が必要となり問題がある。また加工部品の運搬などをする際に変形させてしまう恐れがあるという問題もある。ポータブルスポット溶接機を使用すると溶接機が可動であるため、少人数で作業ができるが、高価なポータブルスポット溶接機が必要となる問題がある。 Further, spot welding is known as a welding method for suppressing distortion deformation. However, when a reinforcing member and an electrical component fixing base are joined to the housing top plate and the housing bottom plate, a problem that the work man-hours increase or the cost is high. There is a problem that requires equipment. In the case of using an inexpensive stationary spot welding machine, when processing a plate material having a large special dimension, the processed parts become heavy, requiring manpower, increasing the work man-hours, or requiring equipment such as a crane. There is also a problem that the workpiece may be deformed when transported. When a portable spot welder is used, since the welder is movable, a small number of people can work. However, there is a problem that an expensive portable spot welder is required.
　また、隅肉溶接で電気品固定台座を接合することは可能であるが、隅肉溶接による接合では筐体に歪み変形が発生し、歪み変形を修正するため作業工数が増える問題がある。 In addition, although it is possible to join the electric product fixing base by fillet welding, there is a problem in that distortion due to the fillet welding occurs in the housing, and the number of work steps increases because the distortion deformation is corrected.
　さらに、少人数で作業ができるリベット締結によって接合することも可能であるが、厳密な気密性を保つために筐体の外側に露出するリベット頭部を別個にシールする作業が必要であり、作業工数が増える問題がある。 In addition, it is possible to join by rivet fastening that allows work with a small number of people, but in order to maintain strict airtightness, it is necessary to separately seal the rivet head exposed to the outside of the housing. There is a problem that man-hours increase.
　本発明は以上の点を考慮してなされたもので、作業工数が少なく強度が高く高品質な電気品収容用筐体及びその製作方法を提案しようとするものである。 The present invention has been made in consideration of the above points, and intends to propose a high-quality housing for housing an electrical product with a small number of work steps and high strength, and a method for manufacturing the same.
　かかる課題を解決するため本発明においては、鉄道車両用電気品を内部に収容する電気品収容用筐体において、鉄道車両用電気品を収容するための複数の小筐体と、複数の小筐体をそれぞれ隣接する小筐体と側面同士が当接した状態に固定する固定材とを備え、各小筐体はそれぞれに１又は複数の部屋が設けられ、各小筐体の正面にはそれぞれ間口が設けられるようにした。 In order to solve such a problem, in the present invention, a plurality of small housings for housing railway vehicle electrical components and a plurality of small housings in an electrical component housing housing for housing rail vehicle electrical components therein. Each of the small housings is provided with one or a plurality of rooms, and each of the small housings is provided on the front surface of each small housing. A frontage was provided.
　また本発明においては、鉄道車両用電気品を内部に収容する電気品収容用筐体における電気品収容用筐体製作方法において、電気品収容用筐体は、鉄道車両用電気品を収容するための複数の小筐体と固定材とを有し、各小筐体はそれぞれに１又は複数の部屋が設けられ、各小筐体の正面にはそれぞれ間口が設けられ、各小筐体それぞれの側面同士を、固定材を用いて当接した状態に固定する第１のステップと、固定材により固定された隣接する小筐体同士の当接部位を覆うようにシール材をシールする第２のステップとを備えるようにした。 According to the present invention, in the method for manufacturing an electrical component housing in the electrical component housing casing that houses the electrical component for a rail vehicle, the electrical component housing case accommodates the rail vehicle electrical component.

　図６に示すように、第１小筐体１００及び第２小筐体１１０は筐体内側に設けられたボルト又はリベットなどの一般的な固定材１６０で接合されている。また気密性を保つために当接部位にシール材１５０を直線状にシールしている。また当接部位は、第１小筐体左側板１０４と第２小筐体右側板１１４とが重なって接合されている。 As shown in FIG. 6, the first small casing 100 and the second small casing 110 are joined by a general fixing material 160 such as a bolt or a rivet provided inside the casing. In order to maintain airtightness, the sealing material 150 is linearly sealed at the contact portion. In addition, the first small casing left side plate 104 and the second small casing right side plate 114 are overlapped and joined to each other at the contact portion.
（２）本実施の形態の効果
　第１小筐体天板１０１、第１小筐体底板１０２、第２小筐体天板１１１、第２小筐体底板１１２、第３小筐体天板１２１及び第３小筐体底板１２２は標準的な大きさの板材で構成することが可能である。このため、これらの板材は安価な小型の打ち抜きプレス機及び曲げ加工機での製作が可能であり、作業工数が少なく済む。 (2) Effects of the First Embodiment The first small casing top plate 101, the first small casing bottom plate 102, the second small casing top plate 111, the second small casing bottom plate 112, and the third small casing top plate 121 and the third small casing bottom plate 122 can be formed of a standard-sized plate material. Therefore, these plate materials can be manufactured by an inexpensive small punching press and bending machine, and the number of work steps can be reduced.
　また図４に示すように、第１小筐体底板１０２、第２小筐体底板１１２及び第３小筐体底板１２２は分割されており、軽量であるため運搬可能である。このため第１電気品固定台座１０３、第２電気品固定台座１１３及び第３電気品固定台座１２３をそれぞれ接合する際に定置式スポット溶接機を用いることができ、安価な設備で歪み変形を抑えて接合することができ作業工数が少なく済む。 As shown in FIG. 4, the first small casing bottom plate 102, the second small casing bottom plate 112, and the third small casing bottom plate 122 are divided and can be transported because they are lightweight. For this reason, a stationary spot welder can be used to join the first electric component fixing base 103, the second electric component fixing base 113, and the third electric component fixing base 123, respectively, and distortion deformation can be suppressed with inexpensive equipment. Can be joined and the number of work steps is reduced.
　さらに、固定材１６０を用いることで安価かつ歪み変形を抑え精度よく接合することが可能である。また固定材１６０が電気品収容用筐体１の外側に露出することがないため、固定材１６０を別個にシールする作業が不要となり、作業が容易になり、作業工数を抑えることができる。また当接部位において板同士が重なって接合されるため板厚が増加し電気品収容用筐体１の強度を高くする。 Furthermore, by using the fixing material 160, it is possible to bond with high accuracy at low cost while suppressing distortion deformation. In addition, since the fixing material 160 is not exposed to the outside of the electrical component housing 1, the work of sealing the fixing material 160 separately becomes unnecessary, the work becomes easy, and the number of work steps can be reduced. Further, since the plates are overlapped and joined at the contact portion, the plate thickness increases and the strength of the electrical component housing 1 is increased.
