Description

本発明は軸の端部を支えて軸の外周面に部品の取付け加工を行なう装置に関するものである。   The present invention relates to an apparatus for mounting a component on an outer peripheral surface of a shaft while supporting an end portion of the shaft.

従来は軸に部品（オーガー等）を取付ける場合、オーガーを全域に渡って軸に密着させる方法がなく部分的に密着させて溶接固定していたが軸とオーガーの軸心が一致しないためその修正に多くの時間を要している。   Previously, when attaching parts (such as an auger) to the shaft, there was no way to make the auger in close contact with the shaft over the entire area, but it was fixed in close contact with the shaft. It takes a lot of time.

軸の外周面に部品を取付けるなどの加工をする場合、通常では先ず軸の両端面にセンター穴を加工しておき、そのセンター穴を利用して軸を両端から押えた状態で部品を所定の位置に取り付ける方法で行なっているが、この軸端面のセンター穴を加工するためには旋盤等で専用の刃物(センタードリル)を使用するため少なからぬ加工工数を必要としている。
また軸の断面形状によって旋盤のチャックを交換する必要が生じる場合があり余計な段取り時間が発生して加工コストに影響しているのが現状である。 When processing parts such as attaching parts to the outer peripheral surface of the shaft, usually, first, center holes are first processed on both end surfaces of the shaft, and the parts are held in place with the shaft pressed from both ends using the center holes. Although it is performed by the method of attaching to the position, in order to machine the center hole of this shaft end surface, a special cutting tool (center drill) is used with a lathe or the like, so a considerable man-hour is required.
Also, depending on the cross-sectional shape of the shaft, it may be necessary to replace the lathe chuck, and an extra setup time is generated, which affects the machining cost.

また、軸が中空(パイプ等)の場合には軸端を例えば円錐形のヘッドで直接押した際に、パイプの端部が変形（ラッパ状に広がる）するという不具合が生じやすい。
更に軸が中空(パイプ等)の場合には端面にセンター穴加工ができないため断面形状と肉厚に合わせてそれぞれに特殊な専用治具を造ることとなり専用治具の製作には工夫と時間を多く要していた。 In addition, when the shaft is hollow (pipe or the like), when the shaft end is directly pressed by, for example, a conical head, there is a tendency that the end of the pipe is deformed (expands in a trumpet shape).
Furthermore, if the shaft is hollow (pipe, etc.), the center hole cannot be drilled on the end face, so a special dedicated jig must be created for each of the cross-sectional shape and thickness. It cost me a lot.

従来より軸の外周面に部品を取付ける場合に軸の端部を支える方法がとられているが端部センター穴を両端から円錐形のヘッドで支持する方法は例えば特開平８−１４９７６２公報に記載されている。
特開平８−１４９７６２公報 Conventionally, a method for supporting the end of the shaft when mounting a part on the outer peripheral surface of the shaft has been adopted. However, a method for supporting the end center hole from both ends with a conical head is described in, for example, Japanese Patent Application Laid-Open No. 8-149762. Has been.

It is detachable and its height can be adjusted.

更に加工台２の一端近くの上面には縁に沿ってピン挿入プレート１０を対向して立設しオーガー押えピン９が挿入可能なように構成されていて、ピン挿入プレート１０にはオーガー押えピン９を挿入する穴１１を複数設けてありオーガーbの巻き方向や軸aの高さに合わせて使用することができる（図１及び図２の（１）または（２））。
またピン挿入プレート１０はオーガーbの羽根の角度にあわせてオーガー押えピン９を挿入できるように位置の調節も可能である。尚、ピン挿入プレート１０は加工台２の一端近くの上面には縁に沿って複数対を設けておくとよい。更に軸aの端部に装着するための軸端保護キャップ８は必用な種類を備えておくとよい。 Further, a pin insertion plate 10 is erected on the upper surface near one end of the processing table 2 along the edge so that an auger presser pin 9 can be inserted. The auger presser pin is included in the pin insertion plate 10. A plurality of holes 11 for inserting 9 are provided and can be used in accordance with the winding direction of the auger b and the height of the shaft a ((1) or (2) in FIGS. 1 and 2).
Further, the position of the pin insertion plate 10 can be adjusted so that the auger presser pin 9 can be inserted in accordance with the angle of the blade of the auger b. The pin insertion plate 10 may be provided with a plurality of pairs along the edge on the upper surface near one end of the processing table 2. Furthermore, the shaft end protection cap 8 to be attached to the end of the shaft a may be provided with a necessary type.

加工台２の上面にオーガーbに挿通した軸aを装着する際には軸aの一端には軸端保護キャップ８を装着し、さらに軸aの他端側の一ヵ所にオーガーを溶接固定しておき軸aの他端を受け側ブロック４の上面に載せた状態でオーガー押えピン９をオーガーbの巻き方向に沿って、対向する２個のピン挿入プレート１０に貫通させてオーガーbが他端方向へずれないように規制しておく。   When the shaft a inserted through the auger b is mounted on the upper surface of the work table 2, a shaft end protective cap 8 is mounted on one end of the shaft a, and the auger is welded and fixed at one position on the other end side of the shaft a. The auger presser pin 9 is passed through the two opposing pin insertion plates 10 along the winding direction of the auger b while the other end of the shaft a is placed on the upper surface of the receiving block 4 and the auger b is inserted. Restrict so that it does not shift in the end direction.

そして加圧機構６を備えた押し側ブロック３を移動させヘッド５を軸端保護キャップ８の端面にあてがって軸aを支持したうえでアクチュエーター７を作動させてヘッド５で軸端保護キャップ８を介して軸aを押すことによって、図２に示す隙間cが図３に示すようにオーガーbの内周を軸aに密着させることができるものである。   Then, the push-side block 3 provided with the pressurizing mechanism 6 is moved, the head 5 is applied to the end surface of the shaft end protection cap 8 to support the shaft a, the actuator 7 is operated, and the head 5 is used to mount the shaft end protection cap 8. By pressing the shaft a through the gap c shown in FIG. 2, the inner periphery of the auger b can be brought into close contact with the shaft a as shown in FIG.

図２は軸加工装置１にオーガーbに挿通した軸aを装着してオーガー押えピン９をオーガーbの巻き方向に沿うようにピン挿入プレート１０の穴に挿入してオーガーbの後端部が先端方向にずれないように規制した状態の平面図の一部であるが、この時点においてはオーガーbの内周と軸aとの間には隙間cが存在している。（１）は左巻きのオーガーの場合、（２）は右巻きオーガーの場合である。   FIG. 2 shows that the shaft a inserted through the auger b is attached to the shaft machining apparatus 1 and the auger presser pin 9 is inserted into the hole of the pin insertion plate 10 along the winding direction of the auger b so that the rear end of the auger b is Although it is a part of the plan view in a state where it is regulated so as not to be displaced in the distal direction, a gap c exists between the inner periphery of the auger b and the shaft a at this point. (1) is for a left-handed auger and (2) is for a right-handed auger.

図３は軸aの端部を軸端保護キャップ８を介して押した状態の部分平面図であり、加圧機構６によってヘッド５が軸端保護キャップ８を介して軸aの端面を押すことによってオーガー押えピン９より先端側のオーガーbが引き伸ばされてオーガーbの内周が縮み軸aに万遍なく密着した状態にすることができる。この際軸とオーガーとの密着部数箇所に軸の先端側方向から振動を与えると更によい（図示せず）。従って密着状態のまま要所を溶接すれば格段に精度が高くブレの少ないオーガー軸を製作できる。   FIG. 3 is a partial plan view of the state where the end of the shaft a is pushed through the shaft end protective cap 8, and the head 5 pushes the end surface of the shaft a through the shaft end protective cap 8 by the pressure mechanism 6. As a result, the auger b on the distal end side of the auger presser pin 9 is stretched, and the inner periphery of the auger b can be contracted so as to be in close contact with the shaft a. At this time, it is better to apply vibrations to the several contact portions between the shaft and the auger from the direction of the tip end of the shaft (not shown). Therefore, an auger shaft with much higher accuracy and less blur can be manufactured by welding important points in close contact.

図４において（１）は軸端保護キャップ８の断面図の例、（２）は軸の形状の概略図の例であり、（１）の（ア）は例えば（２）のＡ，Ｄのような軸端部の断面が円形の丸棒または中空軸(パイプ)、或は（２）のＣ，Ｅのような断面が多角形の軸または中空軸(パイプ)に装着する場合の軸端保護キャップ８であり、（イ）は（ア）と同様であるが２種類の軸径に兼用可能な軸端保護キャップ８である。又（ウ）は例えば（２）のＢのように端部にねじ切り加工された軸に装着する場合の軸端保護キャップ８である。   4, (1) is an example of a cross-sectional view of the shaft end protection cap 8, (2) is an example of a schematic diagram of the shape of the shaft, (1) (a) is, for example, A and D of (2) The shaft end when the shaft end is mounted on a round bar or hollow shaft (pipe) having a circular cross section, or a polygonal shaft or hollow shaft (pipe) having a cross section such as C and E in (2). The protective cap 8 is a shaft end protective cap 8 that is similar to (a) but can be used for two types of shaft diameters. Further, (c) is a shaft end protective cap 8 when it is attached to a shaft threaded at the end as shown in B of (2).

軸端保護キャップ８は図４の（１）に示すように片側は軸端を挿入するべく軸挿入穴８２が開口し反対側は塞がれておりその外側の中心にはセンター穴８１が設けられている。この軸端保護キャップ８は形状が単純で製作も簡単であり、加工する軸の種類に合わせて揃えておけばよく、例えば図４の（２）に示す軸の外径寸法に合うものを軸端に装着すればよい。従って多数ある軸自体の端面にセンター穴加工が不要となるため加工コストが大幅に低減できる。   As shown in (1) of FIG. 4, the shaft end protective cap 8 has a shaft insertion hole 82 opened on one side and closed on the opposite side to insert the shaft end, and a center hole 81 is provided in the center of the outer side. It has been. The shaft end protection cap 8 is simple in shape and easy to manufacture, and may be aligned according to the type of shaft to be processed. For example, a shaft that fits the outer diameter of the shaft shown in FIG. Just attach to the end. Therefore, since the center hole machining is unnecessary on the end surfaces of the shafts themselves, the machining cost can be greatly reduced.

Further, the push side block 3 can be adjusted in the horizontal direction in parallel with the axis, and can also be adjusted in the vertical direction, and the receiving side block 4 is detachable from the mounting portion of the processing table 2, It is configured to be adjustable in the vertical direction.

図６において軸eの両端部に、センター穴８１を有する軸端保護キャップ８を装着して受け側ブロック４’の回転可能なヘッド５’と押し側ブロック３の回転可能なヘッド５を双方の軸端保護キャップ８のセンター穴８１にあてがって加圧機構６によって軸端保護キャップ８を介して軸aを他端方向に押すことにより軸aは回転可能な状態で装着される。
従って軸eが回転可能な状態で装着されることによって図６に示すように軸eの外周面の所定の位置に治具（図示せず）を利用して容易に確実にプレートfを取付ける事ができる。 In FIG. 6, shaft end protection caps 8 having center holes 81 are attached to both ends of the shaft e so that the rotatable head 5 ′ of the receiving side block 4 ′ and the rotatable head 5 of the pushing side block 3 are both disposed. The shaft a is mounted in a rotatable state by being applied to the center hole 81 of the shaft end protection cap 8 and pushing the shaft a in the other end direction by the pressure mechanism 6 through the shaft end protection cap 8.
Therefore, when the shaft e is mounted in a rotatable state, the plate f can be easily and securely attached to a predetermined position on the outer peripheral surface of the shaft e using a jig (not shown) as shown in FIG. Can do.

図８において（１）は左巻きのオーガーに対して左用ストッパープレート６２をオーガー軸側に倒すことによって、また（２）は右巻きのオーガーに対して右用ストッパープレート６３をオーガー軸側に倒すだけでオーガーbの一端側を簡単にズレ止めができる構成になっている。   In FIG. 8, (1) tilts the left stopper plate 62 toward the auger shaft with respect to the left-handed auger, and (2) only tilts the right stopper plate 63 toward the auger shaft with respect to the right-handed auger. With this structure, one end of the auger b can be easily stopped.

加工台２の一端側のオーガー端部のズレ止めのためのオーガー押えピン９或は左用ストッパープレート６２、右用ストッパープレート６３等を利用してオーガーの角度に合わせることによってオーガーの羽根を均一に規制することができるため、オーガーの内周を均等に軸の外周に密着できる効果がある。   The auger blades are uniformly formed by adjusting the angle of the auger using the auger presser pin 9 for stopping the auger end on one end side of the processing table 2 or the stopper plate 62 for the left and the stopper plate 63 for the right. Since it can be regulated, the inner periphery of the auger can be brought into close contact with the outer periphery of the shaft.

従来は軸とオーガーが充分に密着させる方法がなくそのまま（図２の状態）溶接固定していたが軸とオーガーの軸心が一致しないため回転した場合にブレが多く修正に多くの時間を要したり、ブレによる金属疲労で折損などのトラブルが発生していたが、本発明の実施の形態にかかる軸加工装置１によれば容易に軸aの外周にオーガーbの内周が密着状態にできるため、軸aとオーガーbとの密着部を複数個所溶接して固定することによってブレの少ない精度の良いオーガー軸を安定的に製作でき、折損等のトラブルも防ぐことができる。   Conventionally, the shaft and auger are not welded and fixed as they are (as shown in Fig. 2). However, the shaft and auger do not coincide with each other. However, according to the shaft machining apparatus 1 according to the embodiment of the present invention, the inner periphery of the auger b is easily brought into close contact with the outer periphery of the shaft a. Therefore, it is possible to stably produce an auger shaft with less blur and to prevent troubles such as breakage by welding and fixing a plurality of close contact portions between the shaft a and the auger b.

本発明による軸加工装置によれば軸端保護キャップを利用することにより軸の端面にセンター穴加工が不要となることから軸の加工工数の削減が図れるばかりか中空軸即ち筒状の軸や多角形のパイプでも容易に支持して加工することができるものである。   The shaft machining apparatus according to the present invention eliminates the need for center hole machining on the shaft end face by utilizing the shaft end protection cap, so that the number of shaft machining steps can be reduced, and a hollow shaft, that is, a cylindrical shaft or many other shafts can be obtained. Even a square pipe can be easily supported and processed.
