Description
本発明は、シリンダ用ホ−ニング装置に関する。 The present invention relates to a honing device for a cylinder.
沈澱池に配置されるシリンダ駆動方式の汚泥掻寄装置であって、汚泥中で使用されるシリンダ駆動方式で発生しがちなシ−ル性の問題を改善することができる汚泥掻寄装置を先に提案した。 This is a cylinder-driven sludge scraping device that is placed in a sedimentation basin, and is a sludge scraping device that can improve the sealing problem that tends to occur with the cylinder-driven method used in sludge. Proposed to.
この特許文献１には、牽引芯材に取り付けられたピストンと、前後に密封接続部を備えた駆動シリンダにより構成される機体と、機体に取り付けられた汚泥スクレ−パと、機体の前進時に汚泥スクレ−パを掻寄姿勢に切り換え、後退時に非掻寄姿勢に切り換える姿勢切換手段と、駆動シリンダの前側に取り付けられる処理部であって、内部に処理室を有すると共に、牽引芯材の延びた部分が処理室を貫通するように配置される処理部と、を備え、流体制御手段による駆動シリンダ内への水の注入・排出によって、機体を牽引芯材に沿って前進・後退方向に移動可能に構成すると共に、機体の移動時に、処理室内への水の注入・排出を行うものとして構成されている。
ところで、前記駆動シリンダによる汚泥掻寄装置は、従来のワイヤやリンクチェ−ンなどの牽引伝達材と複数のシ−ブを使っての進退牽引方式を採用した汚泥掻寄装置に比べて構造的に非常に簡略化ししかもトラブルも少なくなるなど諸点において有利な装置となるが、只駆動シリンダとして長いものが必要となることは避けられない現実である。沈澱池は矩形をなす特許文献１を例にすれば、その長手方向である前後長が２０ｍ程度の沈澱池に対しては１本が９ｍ前後のシリンダ（チュ−ブ）が必要となり、また、長さが４０ｍ程度であれば２０ｍ前後の長いものが必要となる関係で、１０ｍ前後のシリンダを２本を継ぎ足して対応する必要があった。いずれにしても１本当たり９〜１０ｍ前後の長いもの１本は少なからず必要なものとなる訳で、そうした長いものはホ−ニング仕上げをするにも非常に困難であった。This Patent Document 1 discloses a machine body composed of a piston attached to a traction core, a drive cylinder having front and rear sealed connection parts, a sludge scraper attached to the machine body, and sludge when the machine body moves forward. Position switching means for switching the scraper to a scraping position and switching to a non-scratching position when retreating, and a processing unit attached to the front side of the drive cylinder, having a processing chamber inside, and extending the traction core And a processing part arranged so that the part penetrates the processing chamber, and the body can be moved forward and backward along the traction core by injecting and discharging water into the drive cylinder by the fluid control means In addition, it is configured to inject and discharge water into the processing chamber when the machine body is moved.
By the way, the sludge scraping device using the drive cylinder has a structural structure as compared with a sludge scraping device that uses a traction transmission material such as a wire or a link chain and a forward / backward traction method using a plurality of sheaves. However, it is an apparatus that is advantageous in various respects such as extremely simplified and less troubles, but it is an unavoidable reality that a long drive cylinder is required. For example, in Patent Document 1 in which the sedimentation basin has a rectangular shape, one cylinder (tube) of about 9 m is required for a sedimentation basin whose longitudinal direction is about 20 m. If the length is about 40 m, a long one of about 20 m is required, so it was necessary to add two cylinders of about 10 m to cope with it. In any case, a long one of about 9 to 10 m per piece is not a little necessary, and such a long one is very difficult to finish the honing.
本発明は、このような問題を解決しようとするものであり、極く長いものであっても容易にホ−ニングをして仕上げ程度の高いシリンダチュ−ブを得ることのできるシリンダ用ホ−ニング装置を提供することを目的とする。 The present invention is intended to solve such a problem.

Reference numeral 1 denotes a fixed long base, which includes a main body portion 2 on which grooved steels are arranged opposite to each other, and a receiving plate 3 on the upper surface thereof. The cylinder tube 5 is provided to receive two points around the outer periphery of the cylinder tube 5. One of these outer peripheral rollers-4 is a drive roller, and the cylinder tube 5 is driven to rotate by the drive source 6, the two wheels 7, 8 and the chain 9. It has become. Reference numeral 10 denotes a roller on the outer periphery, which is attached by a fixed base 11 erected from the back side of the gantry 1, a parallel link 12, and a support arm 13, and rides on the outer peripheral upper surface of the cylinder tube 5 and springs. It is designed to ride stably with the force of 14. The upper outer roller 10 is lifted rearward by lifting the support arm 13 in the direction of the arrow in FIG. 3 and tilting the parallel link 12 rearward against the spring 14. -The bu 5 can be attached and detached with a simple operation.
１７はホ−ニング主軸で、図３のように四角（あるいは丸）パイプの長いものからなり、このホ−ニング主軸１７は、シリンダチュ−ブ５内のやや下寄りの位置を通されるとともに、その両端は、架台１に突設された軸受１８に引張軸１９およびナット２０を介して同主軸１７を強力に引っ張るようにして固定されている。軸受１８には上開放状のＵ字形の孔が形成され主軸１７が平行に昇降して脱着可能とされている。尚、この軸受１８は架台１の長手方向に進退調節可能に固定してもよい。 A honing spindle 17 is a long square (or round) pipe as shown in FIG. 3, and the honing spindle 17 is passed through a slightly lower position in the cylinder tube 5. Both ends of the main shaft 17 are fixed to a bearing 18 projecting from the gantry 1 through a tension shaft 19 and a nut 20 so as to be pulled strongly. A U-shaped hole having an open top is formed in the bearing 18 so that the main shaft 17 can be lifted and lowered in parallel. The bearing 18 may be fixed in the longitudinal direction of the gantry 1 so as to be able to advance and retract.
ホ−ニング主軸１７のまわりには、シリンダチュ−ブ５の内周に相対的に接触して回転する複数の内周ロ−ラ−２２とシリンダチュ−ブ５の内周をホ−ニングする複数のホ−ニング工具２３が取り付けられている。２４は止着具である。
尚、２５はスラスト軸受で、シリンダチュ−ブ５の軸方向への勝手な移動を阻止するためのものである。また、シリンダチュ−ブ５は図３の右上欄に示すように上下方向の曲げに強い長い矩形断面をしたものにしてもよい。A plurality of inner peripheral rollers 22 rotating relatively in contact with the inner periphery of the cylinder tube 5 and the inner periphery of the cylinder tube 5 are honed around the main shaft 17. A plurality of honing tools 23 are attached. Reference numeral 24 denotes a fastening tool.
Reference numeral 25 denotes a thrust bearing for preventing an arbitrary movement of the cylinder tube 5 in the axial direction. Further, the cylinder tube 5 may have a long rectangular cross section resistant to bending in the vertical direction as shown in the upper right column of FIG.
外周上ロ−ラ−１０を図３の矢印の方向に退避させた状態で前後の外周下ロ−ラ−４上にシリンダチュ−ブ５を載せ付けセットする。シリンダチュ−ブ５は、それ単独でもよいが、この実施形態の場合は、内部にホ−ニング主軸１７を備えた状態のまま吊り込んでセットする。シリンダチュ−ブ５は両端をスラスト軸受２５に当て付けた状態にするとともに外周上ロ−ラ−１０を図３のように載せ付けて安定状態にする。内部のホ−ニング主軸１７は、持ち上げた状態から降ろして軸受１８に取り付け固定する。その状態で内周ロ−ラ−２２はシリンダチュ−ブ５の内周に転動自在に接触した状態にされるとともにホ−ニング工具２３はシリンダチュ−ブ５の内周に臨むようにされる。ホ−ニング工具２３は図示しない内蔵バネによりシリンダチュ−ブ５の内周に−定以上の圧力で当て付けられるようにすればホ−ニング精度が上がる。 The cylinder tube 5 is mounted and set on the front and rear outer lower rollers 4 with the upper outer roller 10 retracted in the direction of the arrow in FIG. The cylinder tube 5 may be used alone, but in the case of this embodiment, the cylinder tube 5 is suspended and set with the honing main shaft 17 provided therein. The cylinder tube 5 is brought into a state where both ends are brought into contact with the thrust bearing 25 and the outer peripheral roller 10 is placed as shown in FIG. The internal honing spindle 17 is lowered from the lifted state and fixed to the bearing 18. In this state, the inner peripheral roller 22 is brought into contact with the inner periphery of the cylinder tube 5 so as to be capable of rolling, and the honing tool 23 faces the inner periphery of the cylinder tube 5. The If the honing tool 23 is applied to the inner periphery of the cylinder tube 5 with a pressure higher than a constant value by a built-in spring (not shown), the honing accuracy is improved.
ホ−ニングが終わると、外周上ロ−ラ−１０を退避させ、ナット２０を外して軸受１８からホ−ニング主軸１７を上向きに外すことでシリンダチュ−ブ５とともに上方へ離脱させる。その後、ホ−ニング主軸１７からシリンダチュ−ブ５を抜き出す。 When the honing is completed, the outer peripheral upper roller 10 is retracted, the nut 20 is removed, and the honing main shaft 17 is removed upward from the bearing 18 to be separated upward together with the cylinder tube 5. Thereafter, the cylinder tube 5 is extracted from the honing spindle 17.
図４は他の実施形態を示す。図１ないし図３に示すシリンダチュ−ブ５は、ホ−ニング工具２３が長手方向に間隔を置いて配置されているため、その間が空くことで段が形成されることになり、それでは精度アップが図れない。図４の実施形態では、その段付きをなくすようにしたものである。即ち、前記架台１を可動架台２８とし、この可動架台２８を更に下側の固定架台２９に対し可動ロ−ラ−３０により進退移動可能としたものである。固定架台２９の前後には、受材３１に電動や油圧シリンダなどの進退駆動装置３２を備えて可動架台２８を移動させるようにしてある。外周下ロ−ラ−４は固定架台２９側に支持されている。
即ち、ホ−ニング工具２３を備えたホ−ニング主軸１７の側を長手方向に固定化されたシリンダチュ−ブ５に対し相対移動できるようにしてホ−ニング工具２３をシリンダチュ−ブ５に対し相対回転させながらその長手方向にシフトさせて段付のない仕上げを得るようにしたものである。FIG. 4 shows another embodiment. In the cylinder tube 5 shown in FIGS. 1 to 3, since the honing tools 23 are arranged at intervals in the longitudinal direction, a step is formed by the space between them. I can't plan. In the embodiment of FIG. 4, the step is eliminated. That is, the gantry 1 is a movable gantry 28, and the movable gantry 28 can be moved forward and backward by a movable roller 30 with respect to the lower stationary gantry 29. Before and after the fixed gantry 29, the receiving member 31 is provided with an advancing / retreating drive device 32 such as an electric or hydraulic cylinder so that the movable gantry 28 is moved. The outer peripheral lower roller-4 is supported on the fixed mount 29 side.
That is, the honing tool 23 is moved to the cylinder tube 5 such that the honing spindle 17 side provided with the honing tool 23 can be moved relative to the cylinder tube 5 fixed in the longitudinal direction. On the other hand, it is shifted in the longitudinal direction while rotating relative to each other to obtain a stepless finish.
図５は付加的な提案例を示すもので、３５は洗浄通しパイプで、軸受３６により両端で支持された状態でシリンダチュ−ブ５の中を通されており、このパイプ３５に注入口３７を設けて洗浄用水や粉砥石などを注入可能とするとともに、パイプ３５の長手方向に複数配備したノズル３８を通じてこれら洗浄用水や粉砥石などを噴射可能にしてシリンダチュ−ブ５の内面の洗浄をしたり研磨仕上げしたりできるようになっている。図５の右側にしめすようにエア−ノズル３９やオイルノズル４０を設けてエア−やオイルなどをシリンダチュ−ブ５の内面に噴き付け仕上げ精度を上げるようにしてもよい。尚、シリンダチュ−ブ５は水平の他に傾斜姿勢にして水などが流れやすくすることもある。 FIG. 5 shows an additional proposed example. Reference numeral 35 denotes a cleaning through pipe which is passed through the cylinder tube 5 while being supported at both ends by a bearing 36. An inlet 37 is connected to the pipe 35. In order to inject cleaning water, powder grindstones, etc., and to inject the cleaning water, powder grindstones, etc. through a plurality of nozzles 38 arranged in the longitudinal direction of the pipe 35, the inner surface of the cylinder tube 5 can be cleaned. It can be finished or polished. An air nozzle 39 or an oil nozzle 40 may be provided as shown on the right side of FIG. 5, and air or oil may be sprayed onto the inner surface of the cylinder tube 5 to increase the finishing accuracy. In addition to the horizontal, the cylinder tube 5 may be inclined so that water or the like can flow easily.
図６および図７は他の実施形態を示す。同実施形態は、固定架台４３の上にシリンダチュ−ブ４４を安定にセットする一方、両端を軸受４５で回転支持されてホ−ニング主軸４６をシリンダチュ−ブ４４内に通すようにして駆動源４７により回転駆動可能としたもので、ホ−ニング主軸４６回りには、周方向に複数の内周ロ−ラ−４８を配備してシリンダチュ−ブ４４の内周面に沿って転動可能とし、さらにホ−ニング主軸４６の回りには、例えば、２００ｋｇ前後の圧力でシリンダチュ−ブ４４内周面に対し押し付けながら精度の良いホ−ニング加工が可能なよう押圧バネ４９を内蔵した工具ホルダ−５０にホ−ニング工具５１を進退自在に取り付けてある。ホ−ニング工具５１は周方向に複数でかつ長手方向にも複数列をなすように配備してある。 6 and 7 show another embodiment. In this embodiment, the cylinder tube 44 is stably set on the fixed base 43, while the both ends of the cylinder tube 44 are rotatably supported by the bearings 45 so that the honing main shaft 46 passes through the cylinder tube 44. A plurality of inner rollers 48 are provided around the honing main shaft 46 in the circumferential direction so as to roll along the inner peripheral surface of the cylinder tube 44. Further, around the honing main shaft 46, for example, a pressing spring 49 is incorporated so as to enable an accurate honing process while pressing against the inner peripheral surface of the cylinder tube 44 with a pressure of about 200 kg. A honing tool 51 is attached to the tool holder 50 so as to freely advance and retract. A plurality of honing tools 51 are arranged in the circumferential direction and in a plurality of rows in the longitudinal direction.
図８は他の実施形態を示す。同実施形態は、シリンダチュ−ブ４４に対して内周ロ−ラ−４８とホ−ニング工具５１を備えたホ−ニング主軸４６を駆動源４７により回転駆動させるようにしたものにおいて、ホ−ニング工具５１の前後間が空くことによりシリンダチュ−ブ４４の内周面に段が付くことをなくようにしたものである。そのため、ホ−ニング主軸４６をロ−ラ−５５により進退可能な可動架台５６上に軸受５７を介して支持するとともに、同可動架台５６を進退駆動装置５８により駆動させるようにすることで段のないホ−ニング仕上げを可能としたものである。
尚、図８のホ−ニング主軸４６の左端周りに取り付けたものは挿脱ガイド６０で、シリンダチュ−ブ４４の内周面に傷付けせずに摺動可能な太鼓腹状のライニングで、図９に示すように、内周ロ−ラ−４８とホ−ニング工具５１を備えたホ−ニング主軸４６をホ−ニングを終えたのちにシリンダチュ−ブ４４から抜き去る際に同シリンダチュ−ブ４４内に微少隙間をもって嵌まり合いながら摺動ガイドしてホ−ニング工具５１などの側からシリンダチュ−ブ４４の内面を傷つけることなく抜き出すように機能するものである。FIG. 8 shows another embodiment. In the embodiment, a honing main shaft 46 provided with an inner roller 48 and a honing tool 51 is rotationally driven by a driving source 47 with respect to a cylinder tube 44. This is to prevent the inner peripheral surface of the cylinder tube 44 from being stepped due to the space between the front and rear of the ning tool 51. Therefore, the honing main shaft 46 is supported on a movable frame 56 that can be advanced and retracted by a roller 55 via a bearing 57, and the movable frame 56 is driven by an advance / retreat driving device 58. It allows no honing finish.
8 is an insertion / removal guide 60 which is attached around the left end of the honing main shaft 46, and is a drum lining that can slide without damaging the inner peripheral surface of the cylinder tube 44. As shown in FIG. 9, when the honing main shaft 46 provided with the inner peripheral roller 48 and the honing tool 51 is removed from the cylinder tube 44 after the honing is finished, It functions to slide out while fitting with a small gap in the tube 44 and to extract the inner surface of the cylinder tube 44 from the side of the honing tool 51 or the like without damaging it.

尚、図１０の右欄に示すものは、関連する他の大規模ホ−ニング装置で、７４はビルなどの建造物で、同建造物７４を利用してその上位側面に保持ア−ム７５を突設してその上面に駆動源７６を設置するとともにこの駆動源７６により駆動される回転・昇降駆動部７７を関連装備してある。この回転・昇降駆動部７７を駆動することでホ−ニングユニット７８…付きホ−ニング主軸７９をシリンダチュ−ブ８０に対して上下および回転操作可能でこれによりホ−ニング仕上げが可能になる。８１は立直保持装置である。FIG. 10 shows an additional proposal example for a large-scale honing device, in which a vertical holding device 64 is fixed on a horizontal base 63, and the vertical holding device 64 is 10 m or 20 m vertically. A long cylinder tube 65 can be held upright, and a honing unit 66 formed by combining an inner roller and a honing tool is provided around the honing spindle 67. The honing process is performed while the one arranged in the above is made vertical and rotated by a drive source 68. The honing spindle 67 is raised and lowered while being held by an elevating drive guide 71 provided at the tip of a honing heavy machine 70 on the base 63 so as to be vertically elevable, whereby the inner surface of the cylinder tube 65 is not stepped. Honing can be finished.
