【発明が属する技術分野】
本発明は、走行する研磨ベルトにより金属材料、合成樹脂材料及び木質材等からなる各種ワークの角部を研磨して面取り加工する際にワークを支持する面取り研磨装置におけるワーク支持具に関する。
【0002】
【発明が解決しようとする課題】
従来、走行する研磨ベルトの研磨面に各種ワークの角部を押し当てて研磨して面取り加工する際に、作業者は研磨ベルトの上方にて走行直交方向に延出するように取り付けられた定規盤にワークを押し当てて位置決めしながらワークの被面取り部を研磨ベルトの研磨面に当接させて所望形状に研磨している。
【0003】
この面取り作業において、作業者は、定規盤に対してワークを、研磨ベルトの走行力に抗した力で押し付けながらワークの被面取り部を研磨ベルトの研磨面に当接させる必要があるが、熟練度が低い作業者にあっては、定規盤や研磨ベルトに対して一定の力でワークを当接させて研磨することができず、面取り箇所の形状が不均一になったり、面取り量が一定せず、不良品を発生する問題を有している。
【0004】
本発明は、上記した従来の欠点を解決するために発明されたものであり、その課題とする処は、熟練度が低い作業者であっても、研磨ベルトに対してワークを安定した状態で当接させてワークの面取り加工を均一化することができる面取り研磨装置におけるワーク支持具を提供することにある。
【0005】
本発明の他の課題は、熟練度が低い作業者であっても被面取り部をほぼ均一の研磨量で研磨して面取り加工精度を高めることができる面取り研磨装置におけるワーク支持具を提供することにある。
【0006】
【課題を解決するための手段】
本発明は、所定の方向へ走行する研磨ベルトの研磨面に当接するワークを面取り加工する面取り研磨装置において、研磨位置にて研磨ベルトの走行方向と直交する方向へ延出して設ける固定部材と、該固定部材に対して走行直交方向へ移動するように支持される可動部材と、可動部材に対して下端部相互間が所望の間隔をおき、かつ所定の角度をおいて配置され、少なくとも一方が走行直交方向へ移動するように支持されて面取り加工されるワークを支持する一対のワーク支持部材と、可動部材に対して少なくとも一方のワーク支持部材を移動させて一対のワーク支持部材下端部の相互間隔を可変可能にするストローク変更部材とからなることを特徴とする。
【0007】
【発明の実施形態】
以下、本発明の実施形態を図に従って説明する。
先ず、面取り研磨装置1に付いて説明すると、図1において面取り研磨装置1の本体フレーム(図示せず)には金属体や合成樹脂体、または回転体からなるベルト支持体9が固定的に設けられると共に該ベルト支持体9の走行方向上手側及び走行方向下手側に応じた箇所に従動回転体11及び電動モータ等の回転駆動部材15が連結された駆動回転体12が夫々回転可能に設けられ、これら走行支持体9、従動回転体11及び駆動回転体12には走行直交方向が所定幅からなり、上面に研磨面を有した無端状の研磨ベルト13が張設される。そして駆動回転体12の駆動に伴って研磨ベルト13を図示する実線矢印方向へ走行させる。
【0008】
尚、従動回転体11及び駆動回転体12間の本体フレームには圧縮ばね等の弾性部材やエアーシリンダ等の作動部材14に連結された回転体等からなる張力付与部材17が設けられ、作動部材14により張力付与部材17を研磨ベルト13の内周面に圧接させることにより研磨ベルト13に一定の張力を付与している。
【0009】
次に、ワーク支持具19について説明すると、図2〜図4において研磨位置に応じた本体フレーム3の上面にはワーク支持具19が設けられる。該ワーク支持具19の垂直フレーム21は研磨ベルト13の走行直交方向の一方端部側の本体フレーム3に固定され、該垂直フレーム21には研磨ベルト13の上方にて走行直交方向へ延出する長さで、固定部材としての水平フレーム23が上下方向へ移動して高さ調整可能に設けられる。
【0010】
垂直フレーム21に対する水平フレーム23の支持構造としては、垂直フレーム21に上下方向へ延出し、水平フレーム23の端部を上下方向へ移動可能に支持する溝21aを形成すると共に該溝21aの底部に水平フレーム23の昇降ストロークとほぼ一致する長さの長孔21bを形成し、溝21a内にて上下方向へ移動可能に支持された水平フレーム23の一方端部に対し、長孔21bを挿通して抜け止めされる固定ねじ24をねじ止めして垂直フレーム21に対して水平フレーム23を任意の高さ位置で固定可能にさせる構造であればよい。
【0011】
尚、垂直フレーム21に対する水平フレーム23の回動を防止するには、垂直フレーム21に対して水平フレーム23を2本の固定ねじ24で固定するか、図示するように水平フレーム23の端部を異形断面形状とし、溝21aに対する挿嵌により回り止めする構造であればよい。
【0012】
水平フレーム23には可動部材としての可動板25が水平方向へ移動可能で、任意位置で固定して水平方向に対して位置調整可能に構成される。水平フレーム23に対する可動板25の支持構造としては、水平フレーム23に可動板25の移動ストロークに応じた長さの長孔23aを形成し、該長孔23aを挿通して抜け止めされる少なくとも2本の固定ねじ27を可動板25にねじ止めすることにより可動板25を水平方向へ移動可能で、かつ固定可能にさせる構造であればよい。
【0013】
尚、図は2本の固定ねじ27により回り止めした状態で固定する構造としたが、一方を支持軸、他方を固定ねじとして回り止め可能な状態で固定する構造であってもよい。
【0014】
可動板25の垂直フレーム21寄り前面(可動板25における走行方向上手側の面)には一方のワーク支持部材を構成する固定側支持部材29が固定されると共に可動板25の先端部寄り前面には他方のワーク支持部材を構成する可動側支持部材31が、固定側支持部材29に対して互いに近づく方向及び遠ざかる方向へ移動可能に設けられる。
【0015】
固定側支持部材29及び可動側支持部材31は可動板25の前面に配置される固定部29a・31aと、面取り加工されるワークWを支持する支持面部29b・31bから構成される。これら固定側及び可動側支持部材29・31は下端にてワークWの被面取り部Waを研磨ベルト13側へ突出させる間隙37を有し、それぞれの支持面部29b・31bの支持面に沿った仮想延長線が約90度の角度で交差するように配置される。
【0016】
固定側支持部材19は可動板25に対して固定部29aをねじ止めして固定させる。また、可動板25に対して可動側支持部材31を移動可能にする支持構造としては、固定部31aに水平方向へ延出する長孔31cを形成し、該長孔31cを挿通して抜け止めされる支持軸32を可動板25に固定して摺動可能に支持することにより可動側支持部材31を水平方向へ移動可能にさせる構造であればよい。
【0017】
可動側支持部材31にはストローク変更部材33が連結され、該ストローク変更部材33により固定側支持部材29と可動側支持部材31の相互間隔を変更可能にさせる。即ち、水平フレーム23の先端部には支持部35が設けられ、該支持部35の孔35aには回転軸部材33aが回転可能に支持されると共に回転軸部材33aの先端部にねじ部33bが可動側支持部材31のナット部31dに噛合うように形成される。そして回転軸部材33aの回動操作に伴ってねじ部33bとナット部31dの噛合せ量を変更することにより固定側支持部材29に対する可動側支持部材31の水平方向への移動量を調整可能にさせる。
尚、図中の符号33cは回転軸部材33aを回動操作するための摘みである。
【0018】
次に、ワークの面取り作用及びその際のワーク支持作用を説明する。
面取り加工に先立って、研磨ベルト13に対するワークWの研磨位置や研磨量(面取り量)を調整するには、先ず固定ねじ24を緩めて垂直フレーム21に対して水平フレーム23を上下方向へ移動可能にした状態で水平フレーム23をワークWの研磨量に応じた高さにセットした後に固定ねじ24をねじ締めして固定させる。(図5に一点鎖線で示す)
【0019】
また、研磨ベルト13に対するワークWの研磨位置を設定するには、固定ねじ27を緩めて水平フレーム23に対して可動板25を水平方向へ移動可能にした状態で可動板25を所望の研磨位置へ移動させた後に固定ねじ27をねじ締めして固定させる。(図5に二点鎖線で示す)
【0020】
更に、ワークWの面取り量に応じて固定側及び可動側支持部材29・31の相互間隔を調整するには、回転軸部材33aを回動操作してナット部31dに対するねじ部33bの噛合せ量を変更して固定側支持部材29に対して可動側支持部材31を互いに近づく方向或いは遠ざかる方向へ移動し、両者の下端部相互間における間隙37の幅をワークWの面取り量に応じて変更させる。(図6参照)
【0021】
上記状態にて研磨ベルト13を所定の方向へ走行させながらの各支持面部29b・31bの支持面にワークWを支持させた状態で固定側支持部材29及び可動側支持部材31の下端部相互間の間隙37から突出するワークWの被面取り部Waを走行する研磨ベルト13の研磨面に当接可能にさせる。(図7参照)
【0022】
上記状態にて作業者は、ワークWを可動板25の前面、固定側及び可動側支持部材29・31における支持面部29b・31bの支持面のそれぞれに押し当てながら間隙37から突出するワークWの被面取り部Waを走行する研磨ベルト13の研磨面に当接させて研磨することにより面取り加工を行う。
【0023】
その際、固定側及び可動側支持部材29・31の下端部相互の間隙37の幅が予めワークWの面取り量に応じた幅に設定調整されているため、ワークWの被面取り部Waが所定量で面取りされると、固定側及び可動側支持部材29・31によりワークWの被面取り部Waがそれ以上に研磨ベルト13側へ突出することを規制して面取り量をほぼ均一化させる。(図8参照)
【0024】
尚、研磨ベルト13の一定箇所で多数のワークWを面取り加工すると、研磨粉が研磨面の砥粒間に目詰まりして研磨効率が悪くなる。この場合にあっては、水平フレーム23に対する可動板25の位置を変更し、目詰まりしていない研磨ベルト13の研磨箇所に被面取り部Waを当接させて研磨することができ、被面取り部Waを効率的に研磨して面取り加工することができる。
【0025】
本実施形態は、走行する研磨ベルト13によりワークWの被面取り部Waを面取り加工する際に上下方向及び水平方向へ移動調整可能に設けられる固定側及び可動側支持部材29・31により研磨ベルト13に対するワークWの突出量を一定にさせることにより面取り量を均一化することができる。そして被面取り部Waが所定量で研磨されて面取り加工されると、ワークWがそれ以上に研磨ベルト13に当接するのを規制し、ワークWが過度に面取り加工されるのを回避することができる。
【0026】
上記説明は、固定側及び可動側支持部材29・31を、支持面部29b・31bに沿った仮想線が約90度の角度で交差する位置関係で配置する構成としたが、本発明はこの角度に限定されるものではなく、面取り加工されるワークの大きさ、形状等に応じた角度に設定すればよい。
【0027】
上記説明は、垂直フレームに対して水平フレームを、また水平フレームに対して可動板を、更に可動板に対して可動側支持部材をそれぞれに設けられた長孔内にねじを挿通してそれぞれの方向へ移動可能に構成したが、例えば電動モータに連結されたそれぞれの送りねじに、それぞれの可動部に設けられたナットを噛合わせることにより電動モータの駆動に伴ってそれぞれの可動部を移動させる構成であってもよい。この場合にあっては、電動モータとして数値制御されるサーボモータを使用することにより面取り作業における位置設定を自動化することができる。
【0028】
上記説明は、可動板25に対して固定側支持部材29を固定すると共に可動側支持部材31を移動可能に支持して下端における間隙37幅を調整可能にする構成としたが、例えば図9に示すように一本の送りねじ71に螺旋方向が互いに異なるねじ71a・71bを分割形成し、それぞれのねじ71a・71bに、可動板25に対して互いに近づく方向及び遠ざかる方向へ移動するように支持されたワーク支持部材73・75のナット73a・75aを噛合わせ、手動或いは電動モータにより送りねじ71を回転させることによりそれぞれのワーク支持部材73・75を互いに近づく方向及び遠ざかる方向へ同期して相対移動させる構成であってもよい。
【0029】
可動板に対するワーク支持部材の支持構造は、実施形態に示すものと同様にそれぞれのワーク支持部材に水平方向へ延出する長孔を設け、該長孔を挿通するガイド軸を可動板に固定して摺動するように支持すればよい。
尚、実施形態と同一の部材については、同一の符号を付して詳細な説明を省略する。
【0030】
【発明の効果】
本発明は、熟練度が低い作業者であっても、研磨ベルトに対してワークを安定した状態で当接させてワークの面取り加工を均一化することができる。また、熟練度が低い作業者であっても被面取り部をほぼ均一の研磨量で研磨して面取り加工精度を高めることができる。

[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, the chamfering and polishing apparatus 1 will be described. In FIG. 1, a belt support 9 made of a metal body, a synthetic resin body, or a rotating body is fixedly provided on a main body frame (not shown) of the chamfering and polishing apparatus 1. In addition, a driven rotating body 11 and a driving rotating body 12 to which a rotation driving member 15 such as an electric motor is connected are provided rotatably, at positions corresponding to the upper side and the lower side in the running direction of the belt support 9. An endless polishing belt 13 having a predetermined width in the direction perpendicular to the running direction and having a polishing surface on the upper surface is stretched over the traveling support body 9, the driven rotating body 11 and the driving rotating body 12. Then, the polishing belt 13 is caused to travel in the direction indicated by the solid line shown in FIG.
[0008]
The main body frame between the driven rotating body 11 and the driving rotating body 12 is provided with an elastic member such as a compression spring or a tension applying member 17 such as a rotating body connected to an operating member 14 such as an air cylinder. A constant tension is applied to the polishing belt 13 by pressing the tension applying member 17 against the inner peripheral surface of the polishing belt 13 by 14.
[0009]
Next, the work support 19 will be described. In FIGS. 2 to 4, the work support 19 is provided on the upper surface of the main body frame 3 corresponding to the polishing position. The vertical frame 21 of the work support 19 is fixed to the main body frame 3 on one end side of the polishing belt 13 in the direction perpendicular to the traveling direction, and the vertical frame 21 extends above the polishing belt 13 in the direction perpendicular to the traveling direction. The horizontal frame 23 as a fixing member is provided so as to be vertically movable in height and adjustable in height.
[0010]
As a support structure of the horizontal frame 23 with respect to the vertical frame 21, a groove 21 a extending vertically in the vertical frame 21 and supporting an end of the horizontal frame 23 movably in the vertical direction is formed, and a groove 21 a is formed at the bottom of the groove 21 a. An elongated hole 21b having a length substantially coincident with the vertical stroke of the horizontal frame 23 is formed, and the elongated hole 21b is inserted into one end of the horizontal frame 23 supported movably in the vertical direction in the groove 21a. Any structure that allows the horizontal frame 23 to be fixed at an arbitrary height position with respect to the vertical frame 21 by screwing the fixing screw 24 that is prevented from coming off may be used.
[0011]
In order to prevent the horizontal frame 23 from rotating with respect to the vertical frame 21, the horizontal frame 23 is fixed to the vertical frame 21 with two fixing screws 24, or as shown in FIG. Any structure may be used as long as it has an irregular cross-sectional shape and is prevented from rotating by insertion into the groove 21a.
[0012]
A movable plate 25 as a movable member is movable on the horizontal frame 23 in the horizontal direction, and is fixed at an arbitrary position so that the position can be adjusted in the horizontal direction. As a support structure of the movable plate 25 with respect to the horizontal frame 23, at least two holes 23a having a length corresponding to the moving stroke of the movable plate 25 are formed in the horizontal frame 23, and the elongated holes 23a are prevented from being inserted through the elongated holes 23a. Any structure may be used as long as the fixing screw 27 is screwed to the movable plate 25 so that the movable plate 25 can be moved in the horizontal direction and can be fixed.
[0013]
Although the figure shows a structure in which it is fixed in a state where it is prevented from rotating by two fixing screws 27, a structure in which one is used as a support shaft and the other is used as a fixing screw so as to be able to prevent rotation is used.
[0014]
On the front surface of the movable plate 25 closer to the vertical frame 21 (the surface on the upper side in the traveling direction of the movable plate 25), a fixed-side support member 29 constituting one work support member is fixed. The movable support member 31 constituting the other work support member is provided so as to be movable toward and away from the fixed support member 29.
[0015]
The fixed-side support member 29 and the movable-side support member 31 include fixed portions 29a and 31a disposed on the front surface of the movable plate 25, and support surface portions 29b and 31b that support the work W to be chamfered. These fixed-side and movable-side support members 29 and 31 have gaps 37 at their lower ends for projecting the chamfered portions Wa of the work W toward the polishing belt 13, and are imaginary along the support surfaces of the respective support surface portions 29b and 31b. The extensions are arranged so that they intersect at an angle of about 90 degrees.
[0016]
The fixed-side support member 19 fixes the fixed portion 29a to the movable plate 25 by screwing. In addition, as a support structure that enables the movable-side support member 31 to be movable with respect to the movable plate 25, a long hole 31c extending in the horizontal direction is formed in the fixed portion 31a, and the long hole 31c is inserted to prevent it from falling. Any structure may be used as long as the movable support member 31 can be moved in the horizontal direction by fixing the supporting shaft 32 to the movable plate 25 and slidably supporting the movable shaft 25.
[0017]
A stroke changing member 33 is connected to the movable side supporting member 31, and the stroke changing member 33 enables the mutual interval between the fixed side supporting member 29 and the movable side supporting member 31 to be changed. That is, a support portion 35 is provided at the distal end portion of the horizontal frame 23, and the rotary shaft member 33a is rotatably supported in the hole 35a of the support portion 35, and a screw portion 33b is provided at the distal end portion of the rotary shaft member 33a. The movable support member 31 is formed so as to mesh with the nut portion 31d. By changing the amount of engagement between the screw portion 33b and the nut portion 31d with the rotation operation of the rotating shaft member 33a, the amount of movement of the movable-side support member 31 relative to the fixed-side support member 29 in the horizontal direction can be adjusted. Let it.
Reference numeral 33c in the figure is a knob for rotating the rotating shaft member 33a.
[0018]
Next, the work chamfering operation and the work supporting operation at that time will be described.
Prior to chamfering, in order to adjust the polishing position and polishing amount (chamfering amount) of the work W with respect to the polishing belt 13, first, the fixing screw 24 is loosened and the horizontal frame 23 can be moved in the vertical direction with respect to the vertical frame 21. In this state, the horizontal frame 23 is set at a height corresponding to the polishing amount of the work W, and then the fixing screw 24 is screwed and fixed. (Indicated by a dashed line in FIG. 5)
[0019]
Further, in order to set the polishing position of the work W with respect to the polishing belt 13, the movable plate 25 is moved to a desired polishing position in a state where the fixing screw 27 is loosened so that the movable plate 25 can be moved in the horizontal direction with respect to the horizontal frame 23. Then, the fixing screw 27 is screwed and fixed. (Shown by a two-dot chain line in FIG. 5)
[0020]
Further, in order to adjust the mutual interval between the fixed-side and movable-side support members 29 and 31 in accordance with the chamfering amount of the work W, the rotating shaft member 33a is rotated to engage the screw portion 33b with the nut portion 31d. To move the movable-side support member 31 toward or away from the fixed-side support member 29, and change the width of the gap 37 between the lower ends of both in accordance with the chamfering amount of the workpiece W. . (See Fig. 6)
[0021]
While the work W is supported on the support surfaces of the respective support surface portions 29b and 31b while the polishing belt 13 is running in a predetermined direction in the above state, the lower end portions of the fixed-side support member 29 and the movable-side support member 31 are interposed. Of the workpiece W protruding from the gap 37 of the polishing belt 13 running on the chamfered portion Wa of the workpiece W. (See Fig. 7)
[0022]
In the above state, the worker presses the work W against the front surface of the movable plate 25, and the support surfaces of the support surface portions 29b and 31b of the fixed and movable support members 29 and 31, respectively. Chamfering is performed by abutting the polishing surface of the polishing belt 13 traveling on the chamfered portion Wa and polishing.
[0023]
At this time, the width of the gap 37 between the lower ends of the fixed-side and movable-side support members 29 and 31 is set and adjusted in advance to a width corresponding to the chamfering amount of the work W. When the chamfering is performed in a fixed amount, the chamfered portion Wa of the work W is prevented from protruding further toward the polishing belt 13 by the fixed-side and movable-side support members 29 and 31, and the chamfering amount is made substantially uniform. (See Fig. 8)
