Description

本考案は研磨装置に関し、特に、研磨時に砥石を潤滑させる研削液を供給する給液器を一体に備える研磨装置に関する。 The present invention relates to a polishing apparatus, and more particularly to a polishing apparatus that is integrally provided with a liquid feeder that supplies a grinding liquid that lubricates a grindstone during polishing.

研磨装置を回転させる方式の研磨装置では、砥石と研磨対象物との摩擦熱による焼け付きを防止するため、水などの冷却用の研削液を供給しながら研磨作業を行う必要がある。ただし、かかる研削液の供給量が多すぎると砥石と研磨対象物の間の摩擦力が過小となり、好適に研磨作業を行うことができないため、研削液の安定的な供給は重要である。 In a polishing apparatus that rotates the polishing apparatus, it is necessary to perform a polishing operation while supplying a cooling grinding fluid such as water in order to prevent seizure due to frictional heat between the grindstone and the object to be polished. However, if the supply amount of the grinding fluid is too large, the frictional force between the grindstone and the object to be polished becomes too small and the polishing operation cannot be performed suitably. Therefore, stable supply of the grinding fluid is important.

研削液には様々な機能があり、上記の冷却効果のほか、研削粉を混合することで研磨作業の効率化を図ることもできる。本考案においては、研削粉の混合の有無によらず砥石に対して供給する冷却用の液体を研削液を呼称する。 The grinding fluid has various functions, and in addition to the cooling effect described above, it is possible to improve the efficiency of the polishing work by mixing grinding powder. In the present invention, the cooling liquid supplied to the grindstone regardless of whether or not the grinding powder is mixed is called a grinding liquid.

一方、本体中にモータを内設する従来の研磨装置は、モータの回転軸上に円盤の砥石を固定し、回転する砥石により刀具やその他の研磨対象物を研磨する方式を採る。しかし、研磨工程中に適量の水を砥石に加えて冷却／潤滑剤とするに際し、従来の研磨装置の伝動機構は非常に複雑で、かつ給排水構造も不完全であるので、操作が不便であるという欠点があった。 On the other hand, a conventional polishing apparatus in which a motor is installed in a main body employs a method in which a grinding wheel of a disk is fixed on a rotating shaft of a motor, and a tool and other objects to be polished are polished by the rotating grinding stone. However, when an appropriate amount of water is added to the grindstone during the polishing process to make a cooling / lubricant, the transmission mechanism of the conventional polishing apparatus is very complicated and the water supply / drainage structure is incomplete, so the operation is inconvenient. There was a drawback.

これに対し、砥石に冷却水を好適に供給する発明や考案も各種行われており、例えば先行文献１(特許文献１：実公平７−１９７１４号公報)には放射状に配設した複数の研磨チップの間に同心円状に給排水路を設けた研磨装置の考案が記載されている。
実公平７−１９７１４号公報 On the other hand, various inventions and devices for suitably supplying cooling water to a grindstone have been made. For example, in the prior art document 1 (Patent Document 1: Japanese Utility Model Publication No. 7-19714), a plurality of polishings arranged radially. The invention describes a polishing apparatus in which supply and drainage channels are provided concentrically between chips.
No. 7-19714

しかし、上記先行文献１記載の考案による場合、研磨チップを配した基板を高速回転させて研磨作業を行うと、冷却水が該基板の外周縁より飛散して作業場を汚すこととなる。 However, in the case of the device described in the above-mentioned prior art document 1, when the polishing work is performed by rotating the substrate on which the polishing chips are arranged at a high speed, the cooling water is scattered from the outer peripheral edge of the substrate and the work place is soiled.

そこで本考案においては、円盤状の砥石を回転させる方式の研磨装置であって、研削液の供給および排出に際して該液が飛散せず好適に行うことができる小型で部品点数の少ない研磨装置を提供することを目的とする。 Therefore, the present invention provides a polishing apparatus that rotates a disk-shaped grindstone, and is a compact polishing apparatus that has a small number of parts that can be suitably performed without scattering the liquid when supplying and discharging the grinding liquid. The purpose is to do.

本考案者は鋭意検討の末、動力源を内設するハウジング本体の上面に凹陥を設け、該凹陥に円盤状の砥石とその保護環を嵌挿し、研削液を供給することで、研削液の飛散を防止し、好適に該液を供給することのできるとの知見に基づき本考案にかかる研磨装置の完成に到った。 After the intensive study, the inventor provided a recess on the upper surface of the housing body in which the power source is installed, and inserted the disc-shaped grindstone and its protective ring into the recess and supplied the grinding fluid. The polishing apparatus according to the present invention has been completed based on the knowledge that the liquid can be suitably supplied by preventing scattering.

以下、本考案の実施の形態について図面を用いて具体的に説明する。ただし本考案は以下の実施の形態または図面のみに限られるものではない。図１は本考案にかかる研磨装置の全体斜視図、図２その上下分離図である。 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. However, the present invention is not limited to the following embodiments or drawings. FIG. 1 is an overall perspective view of a polishing apparatus according to the present invention, and FIG.

本考案の研磨装置は、ハウジング１、砥石２、給液器３、及び動力源４を主たる構成要素とする。 The polishing apparatus of the present invention has a housing 1, a grindstone 2, a liquid supply device 3, and a power source 4 as main components.

ハウジング１は、上面に砥石２を、内部に動力源４を、それぞれ備える本体である。その形状や材質は特に限定されるものではないが、組立性やメンテナンス性の観点から、上下に分割する方式が好適である。図２ではその例示として上、下ハウジング１１、１２を分離した状態を示している。 The housing 1 is a main body provided with a grindstone 2 on the upper surface and a power source 4 inside. The shape and material are not particularly limited, but from the viewpoints of assemblability and maintainability, a method of dividing vertically is preferable. FIG. 2 shows a state where the upper and lower housings 11 and 12 are separated as an example.

図３は本考案の研磨装置の分解斜視図、図４は平面図、図５および図６はそれぞれ図４のＤ−ＤおよびＣ−Ｃ断面図である。上、下ハウジング１１、１２間には空間を有し、動力源４を収容する。上ハウジング１１の上面には凹陥１３を設け、円盤状の砥石２を遊嵌する。 3 is an exploded perspective view of the polishing apparatus of the present invention, FIG. 4 is a plan view, and FIGS. 5 and 6 are sectional views taken along the lines DD and CC of FIG. 4, respectively. There is a space between the upper and lower housings 11 and 12 to accommodate the power source 4. A recess 13 is provided on the upper surface of the upper housing 11, and the disc-shaped grindstone 2 is loosely fitted.

凹陥１３は、上ハウジング１１を研削しても、環状の突起を設けても、または図３の如くこれらを組み合わせてもよい。凹陥１３の内縁には保護環１３１を嵌設して砥石２を環囲し、凹陥１３底部には研削液の集液のための集液部１４を有する。集液部１４は、外側に排出部１４１を延伸し、砥石に供給された研削液を排出する。排出された研削液は図示しない管路を経て給液器３に戻され、循環型の給液システムを構成することも好適である。 The recess 13 may be obtained by grinding the upper housing 11, providing an annular protrusion, or combining these as shown in FIG. 3. A protective ring 131 is fitted on the inner edge of the recess 13 to surround the grindstone 2, and a liquid collection portion 14 for collecting a grinding liquid is provided at the bottom of the recess 13. The liquid collection unit 14 extends the discharge unit 141 outward and discharges the grinding liquid supplied to the grindstone. It is also preferable that the discharged grinding liquid is returned to the liquid feeder 3 through a pipe line (not shown) to constitute a circulation type liquid supply system.

本考案では、ハウジング１に凹陥１３を設け、ここに砥石２と保護環１３１を嵌め込み、さらに該凹陥１３が研削液の集／排液の機能も有していることから全体として部品点数を削減し、小型の研磨装置を得ることができる。 In the present invention, the recess 1 is provided in the housing 1, the grindstone 2 and the protective ring 131 are fitted therein, and the recess 13 also has a function of collecting / draining the grinding fluid, thereby reducing the number of parts as a whole. In addition, a small polishing apparatus can be obtained.

保護環１３１は、高速で回転する砥石２に誤って手を触れることのないよう、これを環囲する機能のほか、砥石２から遠心力によって外向きに飛散しようとする研削液を遮蔽する機能も有する。形状は特に限定されないが、砥石２の形状にあわせ、開口面は円形とすることが好適である。 The protective ring 131 has a function of surrounding the grinding wheel 2 that rotates at a high speed so as not to accidentally touch it, and a function of shielding the grinding fluid that is about to splash outward from the grinding wheel 2 by centrifugal force. Also have. Although the shape is not particularly limited, it is preferable that the opening surface is circular according to the shape of the grindstone 2.

ハウジング１には給液器３を固設する。給液器３の設置位置や方式は特に限定されないが、研削液の補充作業などの観点から、上ハウジングの上面に突起柱１５を設け、脱着自在に給液器３を嵌着するのが好適である。上ハウジング１１には、凹陥１３の上方に横板１６を設置し、刀具等の研磨対象物を載置して研磨作業を行いやすくするのも好適である。 A liquid feeder 3 is fixed to the housing 1. The installation position and method of the liquid supply device 3 are not particularly limited, but it is preferable to provide a protruding column 15 on the upper surface of the upper housing and attach the liquid supply device 3 detachably from the viewpoint of replenishment work of the grinding fluid. It is. It is also preferable to install a horizontal plate 16 above the recess 13 in the upper housing 11 and place an object to be polished such as a tool to facilitate the polishing operation.

動力源４は、伝動軸４２１を通じて砥石２を回動駆動させるために用いられる。その方式や設置場所は特に限定されるものではないが、動力源４にはモータが用いられ、固定片４１により下ハウジング１１内に固定されることが一般的である。モータ４は下ハウジング１１外部に設けられたスイッチ４３により起動される。モータ４のトルクは減速器４２を伝動して伝動軸４２１を回動させる。伝動軸４２１の一端は上ハウジング１２を穿出して砥石２を軸支し、これを回動させる。 The power source 4 is used for rotationally driving the grindstone 2 through the transmission shaft 421. The method and installation location are not particularly limited, but a motor is used for the power source 4 and is generally fixed in the lower housing 11 by a fixing piece 41. The motor 4 is activated by a switch 43 provided outside the lower housing 11. The torque of the motor 4 is transmitted through the speed reducer 42 to rotate the transmission shaft 421. One end of the transmission shaft 421 penetrates the upper housing 12 to pivotally support the grindstone 2 and rotate it.

減速器４２の採用は任意であり、その形状も特に限定されない。すなわちモータ４を回転軸が鉛直上向きとなるようハウジング１内に固設し、モータ４の回転軸を直接伝動軸４２１に連接することも可能である。 Adoption of the speed reducer 42 is arbitrary, and its shape is not particularly limited. That is, it is possible to fix the motor 4 in the housing 1 so that the rotation axis is vertically upward, and to directly connect the rotation axis of the motor 4 to the transmission shaft 421.

給液器３は上向き開口の空間３１を有し、研削液を貯蔵する。給液器３は砥石２に対応する一側に給液口３２を有し、給液器３内の空間３１の研削液が給液口３２から砥石２上に流れる。給液口３２はひねりボタン３３の制御により出液量の大小を制御する。モータ４の回転数や、研磨対象物による砥石の押圧力に感応するセンサーをハウジング１に設け、研削液の供給量を制御することも好適である。 The liquid feeder 3 has a space 31 having an upward opening and stores the grinding liquid. The liquid supply device 3 has a liquid supply port 32 on one side corresponding to the grindstone 2, and the grinding liquid in the space 31 in the liquid supply device 3 flows from the liquid supply port 32 onto the grindstone 2. The liquid supply port 32 controls the amount of liquid discharge by controlling the twist button 33. It is also preferable to provide the housing 1 with a sensor that is sensitive to the rotational speed of the motor 4 and the pressing force of the grindstone by the object to be polished to control the supply amount of the grinding fluid.

使用者が研磨作業を行う際は、まずスイッチ４３により動力源４を起動して砥石２を回転させ、つぎに給液器３のひねりボタン３３を開いて、給液器３の空間内３１内の研削液を給液口３２から流出させて砥石２上に落とし、研磨時の潤滑液とする。研削液の排液は、砥石２下方の集液部１４に流入し、排液部１４１により排出する。 When the user performs the polishing operation, first, the power source 4 is activated by the switch 43 to rotate the grindstone 2, and then the twist button 33 of the liquid supply device 3 is opened, and the inside of the space 31 of the liquid supply device 3 is opened. This grinding fluid is caused to flow out from the liquid supply port 32 and dropped onto the grindstone 2 to obtain a lubricating fluid during polishing. The drainage of the grinding fluid flows into the liquid collection unit 14 below the grindstone 2 and is discharged by the drainage unit 141.

以上より、使用者は研磨作業中に手作業にて間断なく研削液を供給する必要がなくなるため、研磨の工程が便利かつ円滑となる。 As described above, since the user does not need to supply the grinding liquid manually without interruption during the polishing operation, the polishing process is convenient and smooth.

また供給された研削液は砥石の遠心力によって飛散することなく保護環で遮蔽されて下に落ち、砥石２下方の集液部を経由して排液部よりハウジング外に排出されることから、研磨工程中、排液が作業場を汚すこともない。 Further, the supplied grinding fluid is shielded by the protective ring without being scattered by the centrifugal force of the grindstone, falls down, and is discharged out of the housing from the drainage portion via the liquid collection portion below the grindstone 2. During the polishing process, the drainage does not contaminate the workplace.

本考案にかかる研磨装置は全体として小型で、かつ研削液の給液器を一体として備えるものであるため運搬性に優れる。研磨対象物に応じて砥石に関する従来の発明や考案を組み合わせることにより、かかる運搬性を活かして野外作業を更に効率化する研磨装置を得ることも可能である。 The polishing apparatus according to the present invention is small in size as a whole and is provided with a grinder supply unit as one body, and thus has excellent transportability. By combining conventional inventions and ideas related to a grindstone according to the object to be polished, it is possible to obtain a polishing apparatus that makes use of such transportability and further improves the efficiency of field work.
