Description

この発明は、液体ホーニング用噴射ガン、詳しくは、交換が容易で、ノズル交換の際に芯ズレを起こしにくい液体ホーニング用噴射ガンに関するものである。   The present invention relates to an injection gun for liquid honing, and more particularly, to an injection gun for liquid honing that is easy to replace and hardly causes misalignment during nozzle replacement.

微細な研磨材を水に分散させた懸濁液であるスラリーを被加工物表面に向けて噴射する液体ホーニング加工は、金属部品や各種樹脂加工品などの表面処理に多く使用されている。   Liquid honing, in which a slurry, which is a suspension of fine abrasives dispersed in water, is sprayed toward the surface of a workpiece, is often used for surface treatment of metal parts and various resin processed products.

液体ホーニング加工においては、スラリーに含まれる研磨材は摩耗性が極めて強いので、スラリーを被加工物へ向かって噴射するノズルは摩耗することが避けられず、噴射ガンを一定期間稼動させたら、摩耗が進行したノズルを交換することが行われている。図１は従来の噴射ガンの一例を示したものであり、１はガン本体、２はノズルであり、ノズル２はその軸芯ａに対して直交する方向に締め込まれるセットボルト３によって、ガン本体１に締め付けて固定される様になっている。   In the liquid honing process, the abrasive contained in the slurry is extremely wearable, so it is inevitable that the nozzle that injects the slurry toward the workpiece will be worn out. It is performed to replace the nozzle that has progressed. FIG. 1 shows an example of a conventional injection gun. Reference numeral 1 denotes a gun body, 2 denotes a nozzle, and the nozzle 2 is fixed by a set bolt 3 which is tightened in a direction perpendicular to the axis a. The main body 1 is fastened and fixed.

しかしながら、この従来の固定方法では、ガン本体１とノズル２の接合部がラフな為、ノズル２を交換した際にガン本体１のスラリー排出口４の軸芯とノズル２の軸芯ａとがズレやすく、芯ズレにより所期の噴射性能を発揮し得なくなることが多かった。又、接合部に研磨材が詰まりやすく、ノズル２の交換を困難にしていた。   However, in this conventional fixing method, since the joint between the gun body 1 and the nozzle 2 is rough, when the nozzle 2 is replaced, the axis of the slurry outlet 4 of the gun body 1 and the axis a of the nozzle 2 are It was easy to shift, and it was often impossible to achieve the desired injection performance due to the core shift. In addition, the abrasive is easily clogged in the joint, making it difficult to replace the nozzle 2.

本発明者は液体ホーニングに用いる噴射ガンに関する上記問題点を解決すべく研究を行った結果、ノズル交換の際に、芯ズレが起きにくく、接合部への研磨材の目詰まりもなく、交換作業も容易な液体ホーニング用噴射ガンを開発することに成功し、本発明としてここに提案するものである。   As a result of research conducted to solve the above-mentioned problems related to the spray gun used for liquid honing, the present inventor is less likely to cause misalignment during nozzle replacement, and there is no clogging of the abrasive to the joint, and replacement work The present inventors have succeeded in developing a spray gun for liquid honing that is easy to use, and propose it as the present invention.

略円筒状をなし、軸芯方向一方の端面中央にスラリー排出口が形成されているスラリーチャンバー内に、先端にエアノズルを有する高圧エア導入管が、その先端のエアノズルが前記スラリー排出口近傍に位置する様に、スラリーチャンバーの軸芯と同軸状に挿入されていると共に、スラリーチャンバーの軸芯に対して斜めに偏位して設置されたスラリー供給管路の末端がスラリーチャンバーの周壁面に開口しており、更に、スラリー排出口と同心円状に、それを囲む様に、外周面にオメジが刻まれている円筒状のノズル取付部が一体的に形成されているガン本体と；
軸芯に沿って、一方の端面から他方の端面に達するスラリー用管路が貫通しており、外周面には一対のスナップリング係止溝が形成されている円筒状をなしたノズル本体を、有底円筒形をなし、内周面にはメネジが、底面中央にはノズル本体挿入孔がそれぞれ形成されたスクリューキャップ状のナット部材の前記ノズル本体挿通孔に挿通せしめ、ノズル本体外周面の一対のスナップリング係止溝にそれぞれスナップリングを嵌め込むことにより、ノズル本体にナット部材を取り付けたノズル構成体；
とから液体ホーニング用噴射ガンを構成し、ノズル構成体のナット部材のメネジをガン本体のノズル取付け部のオネジに螺合させることにより、ノズル構成体をガン本体に着脱自在に取付けられる様にして上記課題を解決した。 A high-pressure air introduction tube having an air nozzle at the tip is located in the slurry chamber in which the slurry discharge port is formed at the center of one end surface in the axial direction, and the air nozzle at the tip is positioned in the vicinity of the slurry discharge port. As shown, the end of the slurry supply pipe, which is inserted coaxially with the axis of the slurry chamber and is obliquely displaced with respect to the axis of the slurry chamber, opens to the peripheral wall of the slurry chamber. And a gun body integrally formed with a cylindrical nozzle mounting portion having an outer surface engraved so as to concentrically surround the slurry discharge port;
A cylindrical nozzle body in which a slurry pipe line extending from one end face to the other end face passes through the axis and a pair of snap ring locking grooves are formed on the outer peripheral face. It has a bottomed cylindrical shape, and is inserted into the nozzle body insertion hole of a screw cap-shaped nut member in which a female screw is formed on the inner peripheral surface and a nozzle main body insertion hole is formed in the center of the bottom surface. A nozzle structure in which a nut member is attached to the nozzle body by fitting a snap ring into each of the snap ring locking grooves;
The nozzle assembly is removably attached to the gun body by forming a liquid honing spray gun from the above and screwing the female screw of the nut member of the nozzle structure to the male screw of the nozzle mounting portion of the gun body. Solved the above problem.

ノズル本体を、そのスラリー用管路の軸芯がスラリーチャンバーの軸芯と一致する様に位置決めして、ナット部材のメネジをノズル取付部のオネジに螺合させて、ナット部材をノズル取付部にねじ込めば、ノズル本体はガン本体の外殻にその軸芯方向から圧接して、正確に芯出しされた状態でガン本体に取付けられる。このとき、ノズル本体のスラリー用管路とスラリー排出口と高圧エア導入管のそれぞれの軸芯は完全に一致しており、スラリー供給管路を通ってスラリーチャンバー内に送り込まれたスラリーは、高圧エア導入管によって送り込まれる高圧エアによって加速され、ノズル本体のスラリー用管路を通って噴射され、ホーニング加工の用に供される。   Position the nozzle body so that the axis of the slurry conduit is aligned with the axis of the slurry chamber, screw the female screw of the nut member into the male screw of the nozzle mounting portion, and place the nut member into the nozzle mounting portion. When screwed, the nozzle body is attached to the gun body in an accurately centered state by being pressed against the outer shell of the gun body from the axial direction. At this time, the axes of the slurry conduit, the slurry discharge port, and the high-pressure air introduction tube of the nozzle body are completely aligned, and the slurry fed into the slurry chamber through the slurry supply conduit is high-pressure. Accelerated by the high-pressure air fed by the air introduction pipe, sprayed through the slurry pipe of the nozzle body, and used for honing.

一方、ノズル本体を交換したいときは、ナット部材を緩む方向に回転させて、オネジとメネジの螺合関係を解除すれば、ノズル本体はガン本体のノズル取付部から容易に離脱させることが出来る。そして、新しいノズル本体に一対のスナップリングでナット部材を取付け、これをノズル取付け部に強くネジ込めば、軸芯が一致した状態で新しいノズル本体の取付は完了する。   On the other hand, when it is desired to replace the nozzle body, the nozzle body can be easily detached from the nozzle mounting portion of the gun body by rotating the nut member in the loosening direction and releasing the screwed relationship between the male screw and the female screw. Then, if a nut member is attached to the new nozzle body with a pair of snap rings, and this is firmly screwed into the nozzle attachment portion, the attachment of the new nozzle body is completed with the axial center aligned.

この様に、この発明に係る液体ホーニング用噴射ガンにおいては、ノズル本体をナット部材の螺合により、軸芯方向からガン本体に圧接して固定しているので、芯出しが正確で、芯ズレが起きにくく、しかも、接合部に研磨材が詰まるおそれもなく、ノズル本体の着脱を迅速容易に実施でき、従来の液体ホーニング用噴射ガンに比べ、噴射性能はもちろん、操作性、耐久性、信頼性においても格段に優れている。   As described above, in the liquid honing spray gun according to the present invention, the nozzle body is fixed in pressure contact with the gun body from the axial direction by screwing the nut member. In addition, there is no risk of clogging with abrasives at the joints, and the nozzle body can be attached and detached quickly and easily. Compared to conventional spray guns for liquid honing, as well as operability, durability and reliability. It is also extremely superior in terms of sex.

ノズル本体をスクリューキャップ状のナット部材の螺合により、軸方向からガン本体のスラリー排出口に、それぞれの軸芯が一致する様に圧接させて固定する様にした点に最大の特徴がある。   The greatest feature is that the nozzle body is fixed by being brought into pressure contact with the slurry discharge port of the gun body from the axial direction so that the respective shaft centers coincide with each other by screwing a screw cap-shaped nut member.

図中、５はこの発明に係る液体ホーニング用噴射ガンの主要構成要素であるガン本体であり、その外殻２７の内部には、略円筒状をなしたスラリーチャンバー６が形成されている。そして、このスラリーチャンバー６の軸芯ａ方向一方の端面中央には、スラリー排出口７が成形されている。又、このスラリーチャンバー６の軸芯ａ方向他方の端面中央からは、その軸芯ａに沿って、高圧エア導入管８が挿入され、この高圧エア導入管８の先端に設けられたエアノズル２８は、スラリー排出口７近傍に位置している。又、外殻２７内には、スラリーチャンバー６の軸芯ａに対して斜めに偏位してスラリー供給管路９が形成されており、このスラリー供給管路９の末端は、スラリーチャンバー６の内壁面に開口している。なお、これら構成は、従来の液体ホーニングに用いる噴射ガンと基本的に同一である。   In the figure, reference numeral 5 denotes a gun body which is a main component of the liquid honing spray gun according to the present invention, and a slurry chamber 6 having a substantially cylindrical shape is formed inside the outer shell 27 thereof. A slurry discharge port 7 is formed at the center of one end surface of the slurry chamber 6 in the axis a direction. A high-pressure air introduction pipe 8 is inserted along the axis a from the center of the other end surface of the slurry chamber 6 in the axis a direction, and an air nozzle 28 provided at the tip of the high-pressure air introduction pipe 8 is In the vicinity of the slurry discharge port 7. A slurry supply line 9 is formed in the outer shell 27 obliquely with respect to the axis a of the slurry chamber 6, and the end of the slurry supply line 9 is connected to the slurry chamber 6. Open to the inner wall. These configurations are basically the same as those of a conventional spray gun used for liquid honing.

更に、外殻２７の外側には、スラリー排出口７と同心円状で、かつそれを囲う様に、円筒状のノズル取付部１０が一体的に突設している。又、このノズル取付部１０の外周面にはオネジ１１が刻まれている。   Further, a cylindrical nozzle mounting portion 10 is integrally projected on the outside of the outer shell 27 so as to be concentric with and surround the slurry discharge port 7. A male screw 11 is engraved on the outer peripheral surface of the nozzle mounting portion 10.

一方、図中１２は、ノズル本体１３とこのノズル本体１３に取付けられたナット部材１４とから構成されたノズル構成体である。ノズル本体１３は、耐摩耗性にすぐれた素材からなる円柱状を呈した部材であり、その軸芯に沿って、一方の端面から他方の端面に達するスラリー用管路１５が貫通しており、該スラリー用管路１５の始端側はテーパー状に拡径して漏斗状部１６となっている。又、漏斗状部１６が形成されている始端側の外周面には若干の間隔をあけて一対のスナップリング係止溝１７，１８が設けられている。   On the other hand, reference numeral 12 in the figure denotes a nozzle structure including a nozzle body 13 and a nut member 14 attached to the nozzle body 13. The nozzle body 13 is a cylindrical member made of a material with excellent wear resistance, and the slurry conduit 15 extending from one end face to the other end face passes through the axial core, The starting end side of the slurry conduit 15 is tapered to form a funnel-shaped portion 16. In addition, a pair of snap ring locking grooves 17 and 18 are provided on the outer peripheral surface on the start end side where the funnel-shaped portion 16 is formed with a slight gap.

一方、ナット部材１４は有底円筒状をなし、内周面にはメネジ２４が形成されたスクリューキャップ状の部材であり、その底面中央には、同心円状に、ノズル本体挿通孔１９があけられており、外周面にはローレット加工が施されている。
そして、ノズル本体１３は、前記ナット部材１４のノズル本体挿通孔１９に挿通され、スナップリング係止溝１７，１８にスナップリング２０，２１を嵌め込むことにより、ナット部材１４に固定され、ノズル本体１３とナット部材１４とでノズル構成体１２を構成している、又、前記ノズル取付部１０の内周面の根元付近にはＯリング２５を嵌め込むＯリング嵌め込み溝２２が、ナット部材１４の開口端面内側にはＯリング２６を嵌め込むＯリング嵌め込み溝２３がそれぞれ形成されている。 On the other hand, the nut member 14 has a bottomed cylindrical shape, and is a screw cap-like member having a female screw 24 formed on the inner peripheral surface, and a nozzle body insertion hole 19 is formed concentrically at the center of the bottom surface. The outer peripheral surface is knurled.
The nozzle body 13 is inserted into the nozzle body insertion hole 19 of the nut member 14 and is fixed to the nut member 14 by fitting the snap rings 20 and 21 into the snap ring locking grooves 17 and 18. 13 and the nut member 14 form a nozzle structure 12, and an O-ring fitting groove 22 into which an O-ring 25 is fitted near the base of the inner peripheral surface of the nozzle mounting portion 10. An O-ring fitting groove 23 into which the O-ring 26 is fitted is formed inside the opening end face.

そして、ノズル本体１３を、そのスラリー用管路１５の軸芯がスラリーチャンバー６の軸芯ａと一致し、かつ、漏斗状部１６がスラリー排出口７直下に来る様に位置決めして、ナット部材１４のメネジ２４をノズル取付部１０のオネジ１１に螺合させて、ナット部材１４をノズル取付部１０にねじ込めば、ノズル本体１３はガン本体５の外殻２７にその軸芯方向から圧接して、正確に芯出しされた状態でガン本体５に取付けられる。   Then, the nozzle body 13 is positioned such that the axis of the slurry conduit 15 coincides with the axis a of the slurry chamber 6 and the funnel-shaped portion 16 is directly below the slurry discharge port 7, and the nut member When the female screw 24 of 14 is screwed into the male screw 11 of the nozzle mounting portion 10 and the nut member 14 is screwed into the nozzle mounting portion 10, the nozzle body 13 is pressed against the outer shell 27 of the gun body 5 from the axial direction. Then, it is attached to the gun body 5 in a state of being accurately centered.

この状態において、ノズル本体１３のスラリー用管路１５とスラリー排出口７と高圧エア導入管８のそれぞれの軸芯は完全に一致しており、スラリー供給管路９を通ってスラリーチャンバー６内に送り込まれたスラリーは、高圧エア導入管８によって送り込まれる高圧エアによって加速され、ノズル本体１３のスラリー用管路１５を通って噴射され、ホーニング加工の用に供される。   In this state, the axes of the slurry conduit 15, the slurry discharge port 7, and the high-pressure air introduction tube 8 of the nozzle body 13 are completely coincident with each other and pass through the slurry supply conduit 9 into the slurry chamber 6. The fed slurry is accelerated by the high-pressure air fed by the high-pressure air introduction pipe 8, is sprayed through the slurry conduit 15 of the nozzle body 13, and is used for honing.

一方、ノズル本体１３を交換したいときは、ナット部材１４を緩む方向に回転させて、オネジ１１とメネジ２４の螺合関係を解除すれば、ノズル本体１３はガン本体５のノズル取付部１０から容易に離脱させることが出来る。   On the other hand, when the nozzle body 13 is to be replaced, the nozzle body 13 can be easily removed from the nozzle mounting portion 10 of the gun body 5 by rotating the nut member 14 in the loosening direction and releasing the screwed relationship between the male screw 11 and the female screw 24. Can be removed.

そして、新しいノズル本体１３にスナップリング２０，２１でナット部材１４を取付け、これをノズル取付け部１０に強くネジ込めば、軸芯が一致した状態で新しいノズル本体１３の取付は完了する。なお、ノズル本体１３とノズル取付部１０の接触箇所及びナット部材１４とノズル取付部１０の接触箇所は、それぞれＯリング２５及び２６で確実に封止されているので、スラリーに含まれる研磨材が接合部に詰まることはなく、ノズル本体１３の着脱は、いつでもスムーズに行うことが出来る。   If the nut member 14 is attached to the new nozzle body 13 with the snap rings 20 and 21 and is screwed into the nozzle attachment portion 10, the attachment of the new nozzle body 13 is completed in a state where the axes are aligned. In addition, since the contact part of the nozzle main body 13 and the nozzle attachment part 10 and the contact part of the nut member 14 and the nozzle attachment part 10 are each reliably sealed by O-rings 25 and 26, the abrasives contained in the slurry are The joint portion is not clogged, and the nozzle body 13 can be attached and detached smoothly at any time.

この発明に係る液体ホーニング用噴射ガンは、ノズル本体をナット部材の螺合により、軸芯方向からガン本体に圧接して固定しているので、芯出しが正確で、芯ズレが起きにくく、しかも、接合部に研磨材が詰まるおそれもなく、ノズル本体の着脱を迅速容易に実施でき、従来の液体ホーニング用噴射ガンに比べ、噴射性能はもちろん、操作性、耐久性、信頼性においても格段に優れている。   In the liquid honing gun according to the present invention, the nozzle body is fixed by being pressed against the gun body from the axial direction by screwing the nut member, so that the centering is accurate and the misalignment is difficult to occur. In addition, there is no risk of clogging with abrasives in the joints, and the nozzle body can be attached and detached quickly and easily. In addition to jetting performance, conventional jet guns for liquid honing, as well as operability, durability, and reliability. Are better.

液体ホーニングが実施される各種金属部品や合成樹脂加工品の表面処理や表面加工の際に大いに利用価値がある。   It is of great utility in the surface treatment and surface processing of various metal parts and synthetic resin processed products that are subjected to liquid honing.
