However, there may be cases where the web cannot be fully ground due to poor installation and alignment of the processing rollers. In addition, even for a workpiece that has been subjected to surface processing, there may be cases where unpolished surfaces occur on the processed surface due to mounting alignment of the workpiece. It is not possible to make a program that makes the processing belt walk along the processing surface in accordance with the subtle ups and downs of the processing surface every time.

The roller body 42 has a center hole 42a through which the rotation shaft 38 passes. A groove 42b for passing the tenon 38a and extending in the axial direction may be formed on the inner peripheral surface of the roller body 42 . One end portion of the roller body 42 is provided with a flange portion 42 c that prevents the elastic ring 44 from coming off and protrudes in the radial direction. At the other end of the roller body 42, a recessed portion 42d for accommodating the end plate 48 is formed.

彈性環44是由安裝於輥本體42的外周面的發泡橡膠，例如如氟橡膠海綿的彈性材料所形成的環狀構件。彈性環44具有朝周方向延伸的狹縫44a、及密接於輥本體42的外周面的內周面44b。狹縫44a是從彈性環44的外周面朝半徑方向以預定深度、朝軸方向以預定的寬幅(軸方向尺寸)形成。狹縫44a也可以僅是從外周面朝半徑方向以預訂深度切入之切口。The elastic ring 44 is an annular member formed of foam rubber attached to the outer peripheral surface of the roller body 42 , for example, an elastic material such as fluororubber sponge. The elastic ring 44 has a slit 44a extending in the circumferential direction, and an inner peripheral surface 44b in close contact with the outer peripheral surface of the roller body 42 . The slit 44 a is formed at a predetermined depth in the radial direction from the outer peripheral surface of the elastic ring 44 and has a predetermined width (dimension in the axial direction) in the axial direction. The slit 44a may only be a notch cut at a predetermined depth from the outer peripheral surface toward the radial direction.

狹縫44a嵌入有防止彈性環44因第1輥40旋轉時的離心力而朝半徑方向膨脹、變形的膨脹防止構件46。膨脹防止構件46可作成由彈性率比作為彈性體的彈性環44還大的材料，例如樹酯製薄板而成的環形構件。或是，膨脹防止構件46也可是將上述環形構件沿著直徑2分割後的2個弓形構件或以中心角成為120°的方式3等分後的3個弓形構件。再者，膨脹防止構件46和加工帶34接觸時，會對加工帶34的架設造成不好影響，所以膨脹防止構件46的外徑以在加工時及在非加工時皆比彈性環44的外徑還小者為佳。The slit 44a is fitted with an expansion preventing member 46 that prevents the elastic ring 44 from expanding and deforming in the radial direction due to the centrifugal force when the first roller 40 rotates. The expansion preventing member 46 can be formed as an annular member made of a material having a higher elastic modulus than the elastic ring 44 which is an elastic body, for example, a resin thin plate. Alternatively, the expansion preventing member 46 may be two arcuate members obtained by dividing the annular member along the diameter into two or three arcuate members obtained by dividing the circular member into three equal parts such that the central angle becomes 120°. Furthermore, when the expansion prevention member 46 contacts the processing belt 34, it will have a bad influence on the erection of the processing belt 34, so the outer diameter of the expansion prevention member 46 is larger than the outer diameter of the elastic ring 44 during processing and non-processing. Smaller ones are better.

端板48具有圓筒狀的本體部分48a、及於該本體部分48a的其中一端部朝半徑方向突出的凸緣部48b。端板48形成有供旋轉軸38通過的中心孔48c。將端板48嵌合於輥本體42的凹部42d時，嵌合於輥本體42的外周面的彈性環44便夾持於輥本體42的凸緣部42c和端板48的凸緣部48b之間。藉此，防止彈性環44對輥本體42朝軸方向移動而脫離。The end plate 48 has a cylindrical main body portion 48a and a flange portion 48b protruding radially from one end portion of the main body portion 48a. The end plate 48 is formed with a center hole 48c through which the rotation shaft 38 passes. When the end plate 48 is fitted into the concave portion 42d of the roller body 42, the elastic ring 44 fitted on the outer peripheral surface of the roller body 42 is clamped between the flange portion 42c of the roller body 42 and the flange portion 48b of the end plate 48. between. Thereby, the elastic ring 44 is prevented from moving and detaching from the roller body 42 in the axial direction.

第2輥32安裝在可旋轉地支撐於コ字形的搖架50的旋轉軸52。搖架50是設成可沿著導件59朝箭頭A所示的方向移動。螺釘(stud)54固定於托架36，具有間隙地貫入搖架50的孔(圖未示)，在螺釘54的周圍配設螺旋彈簧56。搖架50藉由螺旋彈簧56而朝從托架36遠離的方向賦予勢能。搖架50可藉由為固定機構的銷58，而在從托架36分離任意距離的狀態固定。具體來說，利用作成銷58貫通螺合於搖架50且銷58的前端抵接於貫入到搖架50內部的螺釘54的外周，而可在使銷58旋轉動作時，固定搖架50的位置。於加工帶的交換作業中，在將加工帶卸除的情況，首先解除銷58的固定，使搖架50沿著導件59接近於托架36，將銷58固定，作成已將加工帶34的架設狀態解除了的狀態之後，可從第1輥40和第2輥32將加工帶34卸除。又，在進行加工帶34的安裝的情況，於已將上述之加工帶34卸除的狀態下，將要新安裝的加工帶34安裝於第1輥40和第2輥32，解除銷58的固定時，搖架50藉由螺旋彈簧56的彈力而從托架36分離，加工帶34成為架設狀態，所以進一步藉由銷58來固定搖架50的位置，藉以完成加工帶34的安裝。藉由該等構造和作業順序，不管作業者的熟練度而可進行帶的交換作業，且可設定加工帶34的張力。The second roller 32 is attached to a rotating shaft 52 rotatably supported by a U-shaped cradle 50 . The cradle 50 is configured to be movable in the direction indicated by the arrow A along the guide 59 . A screw (stud) 54 is fixed to the bracket 36 and penetrates a hole (not shown) of the cradle 50 with a gap, and a coil spring 56 is arranged around the screw 54 . The cradle 50 is given potential energy in a direction away from the bracket 36 by the coil spring 56 . The cradle 50 can be fixed in a state separated from the bracket 36 by an arbitrary distance by a pin 58 as a fixing mechanism. Specifically, when the pin 58 is threaded through the cradle 50 and the front end of the pin 58 abuts against the outer periphery of the screw 54 penetrating into the cradle 50, the cradle 50 can be fixed when the pin 58 is rotated. Location. In the exchange operation of the processing belt, when the processing belt is removed, the fixing of the pin 58 is first released, the cradle 50 is approached to the bracket 36 along the guide 59, and the pin 58 is fixed to make the processing belt 34 The processing belt 34 can be removed from the first roller 40 and the second roller 32 after the suspended state of the roller is released. Also, in the case of installing the processing belt 34, in the state where the above-mentioned processing belt 34 has been removed, the processing belt 34 to be newly installed is installed on the first roller 40 and the second roller 32, and the fixing of the pin 58 is released. At this time, the cradle 50 is separated from the bracket 36 by the elastic force of the coil spring 56, and the processing belt 34 becomes an erected state, so the position of the cradle 50 is further fixed by the pin 58, so as to complete the installation of the processing belt 34. With these structures and work procedures, the belt exchange work can be performed regardless of the operator's proficiency, and the tension of the processing belt 34 can be set.

旋轉動力產生部60具備旋轉馬達。旋轉馬達可以是電動馬達，然而以流體馬達，特別是具備渦輪(圖未示)的氣動馬達為佳。作為旋轉動力產生部60的氣動馬達具有可旋轉地收納渦輪的汽缸64、及形成連通於汽缸64的流體入口埠66的渦輪殼體62。流體入口埠66連通於流體供給通路。在本實施型態中，流體入口埠66連通於固定器部12及結合部28的中心孔12a、28c。The rotational power generation unit 60 includes a rotational motor. The rotary motor can be an electric motor, but is preferably a fluid motor, especially an air motor with a turbine (not shown). The air motor serving as the rotational power generator 60 has a cylinder 64 rotatably housing a turbine, and a turbine housing 62 forming a fluid inlet port 66 communicating with the cylinder 64 . The fluid inlet port 66 communicates with the fluid supply passage. In this embodiment, the fluid inlet port 66 communicates with the central holes 12 a and 28 c of the holder part 12 and the coupling part 28 .

動力傳遞部70具備有第1滑輪72、第2滑輪74、被架設在第1滑輪72和第2滑輪74之間的驅動帶76、及張力器78。第1滑輪72以和作為旋轉動力產生部60的氣動馬達的輸出軸68一起旋轉的方式安裝於輸出軸68，形成輸入滑輪。第2滑輪74是以和第1輥40用的旋轉軸38一起旋轉的方式安裝於旋轉軸38。驅動帶76可作成齒形帶或鑲齒帶(cog belt)。驅動帶76為齒形帶或鑲齒帶的情況，第1滑輪72和第2滑輪74是藉由具有卡合於驅動帶76的齒的複數個齒之齒形滑輪所形成。驅動帶76藉由具有在第1滑輪72和第2滑輪74之間卡合於驅動帶76的背面的滑動輥78a的張力器78而施加一定的張力。The power transmission unit 70 includes a first pulley 72 , a second pulley 74 , a drive belt 76 spanned between the first pulley 72 and the second pulley 74 , and a tensioner 78 . The 1st pulley 72 is attached to the output shaft 68 so that it may rotate together with the output shaft 68 of the air motor which is the rotational power generation part 60, and forms an input pulley. The second pulley 74 is attached to the rotating shaft 38 so as to rotate together with the rotating shaft 38 for the first roller 40 . The drive belt 76 can be implemented as a toothed or cog belt. When the driving belt 76 is a toothed belt or a cogged belt, the first pulley 72 and the second pulley 74 are formed by a toothed pulley having a plurality of teeth engaged with the teeth of the driving belt 76 . A constant tension is applied to the drive belt 76 by a tensioner 78 having a slide roller 78 a engaged with the back surface of the drive belt 76 between the first pulley 72 and the second pulley 74 .

將帶加工裝置10夾持於工作機械100的主軸114的錐形孔內時，流體供給通路12a、28c便連通於夾持裝置的拉桿的流體通路。流體例如加壓空氣或冷媒從流體供給源通過主軸的工具夾持裝置的拉桿的流體通路、帶加工裝置10的流體供給通路12a、28c及作為旋轉動力產生部60的流體馬達的流體入口埠66而供給到汽缸64，使配設於該汽缸64內的渦輪旋轉。When the tape processing device 10 is clamped in the tapered hole of the spindle 114 of the machine tool 100, the fluid supply passages 12a, 28c communicate with the fluid passages of the tie rods of the clamping device. Fluid such as pressurized air or refrigerant passes from the fluid supply source through the fluid passage of the tie rod of the tool clamping device of the main shaft, the fluid supply passages 12a, 28c of the belt processing device 10, and the fluid inlet port 66 of the fluid motor as the rotational power generation part 60 And it is supplied to the cylinder 64, and the turbine arrange|positioned in this cylinder 64 is rotated.

該旋轉是通過安裝於流體馬達的輸出軸68的第1滑輪72、驅動帶76及第2滑輪74而傳遞到旋轉軸38，因而，為加工輥之第1輥40旋轉，被架設在第1輥40和第2輥32之間的加工帶34便被驅動。其間，第1輥40作為驅動輥，而且第2輥32作為從動輥而作用。如此，使加工帶34驅動以使在第1輥40和第2輥32之間循環的期間，將加工帶34夾於其間且將第1輥40壓附到工件W的表面，且使主軸114和工作台104相對移動，藉此工件W的表面被加工(研磨或研削)。This rotation is transmitted to the rotating shaft 38 through the first pulley 72, the drive belt 76, and the second pulley 74 installed on the output shaft 68 of the fluid motor. Therefore, the first roller 40, which is a processing roller, rotates and is mounted on the first roller. The processing belt 34 between the roller 40 and the second roller 32 is driven. Meanwhile, the first roller 40 functions as a driving roller, and the second roller 32 functions as a driven roller. In this way, while the processing belt 34 is driven to circulate between the first roller 40 and the second roller 32, the processing belt 34 is sandwiched therebetween, the first roller 40 is pressed against the surface of the workpiece W, and the main shaft 114 By moving relative to the table 104, the surface of the workpiece W is processed (grinded or ground).

藉由將為彈性體的彈性環44配設在為加工輥之第1輥40的外周部，而可藉由彈性體將加工時成為問題的加工輥的安裝對位不良或成為加工對象的工件表面的起伏形狀等吸收，不用作成特別的程式，只要依據配合設計形狀的加工程式(NC程式)沿著工件W的要加工表面來使帶加工裝置行走，便可獲得良好的加工面。又，在彈性環44埋設膨脹防止構件46，於第1輥40的旋轉中，防止彈性環44因離心力而朝半徑方向膨脹、變形。也就是，可藉由膨脹防止構件46來解決意外的張力施加於加工帶34而對朝工件W的加工產生不好影響的課題、或是於未卡合於加工帶34的部分，彈性環44膨脹而與本體部20的各處產生干涉的課題。By arranging the elastic ring 44 which will be an elastic body on the outer peripheral portion of the first roll 40 which is a processing roll, it is possible to use the elastic body to prevent the mounting alignment of the processing roll which is a problem during processing or the workpiece to be processed. It is not necessary to make a special program for absorbing surface undulations, etc., as long as the belt processing device is run along the surface to be processed of the workpiece W according to the processing program (NC program) matching the designed shape, a good processed surface can be obtained. In addition, an expansion preventing member 46 is embedded in the elastic ring 44 to prevent the elastic ring 44 from expanding and deforming in the radial direction due to centrifugal force during the rotation of the first roller 40 . That is, the problem that unintentional tension is applied to the processing belt 34 to adversely affect the processing of the workpiece W can be solved by the expansion prevention member 46, or the elastic ring 44 can be closed at the portion that is not engaged with the processing belt 34 . There is a problem that it expands and interferes with various parts of the main body part 20 .

在上述實施型態中，膨脹防止構件46是從彈性環44的各個的外周面朝半徑方向以預定深度、朝軸方向以預定寬幅(軸方向尺寸)而形成且配設於朝周方向延伸的狹縫44a內之例如由樹酯製薄板而成的環狀構件、2個弓形構件或3個弓形構件，然而本發明不限定於此。本發明中，膨脹防止構件只要是可防止配設於加工輥的外周面的彈性體在加工輥的旋轉中因離心力而朝半徑方向膨脹、變形即可。In the above-described embodiment, the expansion preventing member 46 is formed at a predetermined depth in the radial direction from each outer peripheral surface of the elastic ring 44 and has a predetermined width (dimension in the axial direction) in the axial direction, and is arranged to extend in the circumferential direction. In the slit 44a, for example, a ring-shaped member made of a thin resin plate, two arched members, or three arcuate members, however, the present invention is not limited thereto. In the present invention, the expansion preventing member may prevent the elastic body arranged on the outer peripheral surface of the processing roll from expanding and deforming in the radial direction due to centrifugal force during the rotation of the processing roll.

圖7顯示加工輥的變形例即第1輥120。本實施形態的第1輥120除了作為彈性體的彈性環及膨脹防止構件是和上述之實施型態中的膨脹防止構件46不同的點之外，是和上述之實施形態中之第1輥40大致構成為相同。FIG. 7 shows the first roll 120 which is a modified example of the processing roll. The first roller 120 of this embodiment is the same as the first roller 40 in the above-mentioned embodiment except that the elastic ring which is an elastic body and the expansion preventing member are different from the expansion preventing member 46 in the above-mentioned embodiment. roughly the same configuration.

圖7中，彈性環124具有朝周方向延伸的狹縫124a。狹縫124a是於彈性環124的軸方向從相反側的2個側面以預定的深度、於半徑方向以預定的寬幅(半徑方向尺寸)形成。狹縫124a可嵌入膨脹防止構件126a、126b，前述膨脹防止構件126a、126b防止彈性環124因第1輥120的旋轉所產生的離心力而朝半徑方向膨脹、變形。In FIG. 7, the elastic ring 124 has a slit 124a extending in the circumferential direction. The slit 124a is formed with a predetermined depth from two opposite side surfaces in the axial direction of the elastic ring 124 and with a predetermined width (dimension in the radial direction) in the radial direction. The slit 124a can be fitted with anti-expansion members 126a and 126b that prevent the elastic ring 124 from expanding and deforming in the radial direction due to the centrifugal force generated by the rotation of the first roller 120 .

膨脹防止構件126a、126b可例如作成由樹脂製薄板而成之環狀構件。或是，膨脹防止構件126a、126b也可是做成將上述環狀構件沿著直徑2分割後的2個弓形構件、或將上述環狀構件以中心角成為120°的方式3分割後的3個弓形構件。膨脹防止構件126a配設於端板128的凸緣部128b的狹縫128d及形成在與該狹縫128d相對面的彈性環124的側面之狹縫124a，膨脹防止構件126b配設在2個彈性環124的相對面之側面的狹縫124a，膨脹防止構件126c配設在輥本體122的凸緣部122c的狹縫122e及與該狹縫122e相對面的彈性環124之側面的狹縫124a內。The expansion prevention members 126a and 126b can be made, for example, as ring-shaped members made of thin resin plates. Alternatively, the expansion preventing members 126a and 126b may be made into two arcuate members obtained by dividing the above-mentioned ring-shaped member along the diameter, or three parts obtained by dividing the above-mentioned ring-shaped member into three such that the central angle becomes 120°. bow member. The expansion prevention member 126a is disposed on the slit 128d of the flange portion 128b of the end plate 128 and the slit 124a formed on the side surface of the elastic ring 124 opposite to the slit 128d, and the expansion prevention member 126b is disposed on two elastic rings. The slit 124a on the side surface opposite to the ring 124, and the expansion preventing member 126c are arranged in the slit 122e of the flange portion 122c of the roller body 122 and the slit 124a on the side surface of the elastic ring 124 opposite to the slit 122e. .

圖7的第1輥120也和上述實施型態的第1輥40同樣地作用。The 1st roller 120 of FIG. 7 also functions similarly to the 1st roller 40 of the said embodiment.

主軸114由於可進行對工件W朝X軸、Y軸及Z軸之直交的3個軸方向相對地移動及定位、以及繞旋轉軸線O的角度定位，所以可依據工作機械100和帶加工裝置10對工件W進行帶加工，前述帶加工是在設於真空腔等之精密的密封面形成具有與適合的工具進給方向平行的研磨痕或研削痕的研磨精加工面或研削精加工面。又，藉由工作機械100具備有工具交換裝置，而可將利用帶加工裝置10進行的研磨或研削以外的加工步驟匯集在利用工作機械100進行的加工步驟。再者，利用將流體馬達或氣動馬達適用於旋轉馬達，而可藉由將工作機械100為了潤滑或冷卻而原本就具備有的冷媒或加壓空氣等供給的流體供給源，來驅動帶加工裝置10，所以不需要為了帶加工裝置10而新設驅動源。Since the main shaft 114 can relatively move and position the workpiece W in the three orthogonal directions of the X-axis, Y-axis and Z-axis, as well as angularly position around the rotation axis O, it can be used according to the machine tool 100 and the belt processing device 10. The workpiece W is subjected to tape processing. The tape processing is to form a ground-finished surface or a ground-finished surface having grinding marks or grinding marks parallel to an appropriate tool feed direction on a precision sealing surface provided in a vacuum chamber or the like. Furthermore, since the machine tool 100 is provided with the tool exchange device, processing steps other than grinding and grinding performed by the belt processing device 10 can be integrated into the processing steps performed by the machine tool 100 . Furthermore, by applying a fluid motor or an air motor to a rotary motor, the tape processing device can be driven by a fluid supply source that supplies a refrigerant or pressurized air, etc., which are originally provided in the machine tool 100 for lubrication or cooling. 10, so there is no need to newly provide a drive source for the tape processing device 10.

在上述的內容中，雖就在1個彈性環裝設有1個或2個膨脹防止構件的實施型態來進行說明，然而也可在想更強力地防止因離心力所造成之彈性環的膨脹的情況等，因應必要來裝設更多的膨脹防止構件。In the above content, although one or two expansion prevention members are installed on one elastic ring, it is also possible to prevent the expansion of the elastic ring caused by centrifugal force more strongly. Depending on the situation, etc., install more expansion preventing members as necessary.
