Description

本発明は、機械加工における被加工物であるワークの固定方法に関し、特に、磁石式ワーク固定法などが使えない非鉄金属、セラミックス、ガラスなどの材料でできたワークや、さらには、面積の大きい薄板や、重いワーク、長尺物および低い強度の壊れやすいもの等を固定して機械加工を施すことに用いて有効である。   The present invention relates to a method for fixing a workpiece, which is a workpiece in machining, and in particular, a workpiece made of a material such as a non-ferrous metal, ceramics, or glass that cannot use a magnet-type workpiece fixing method, or a large area. It is effective for machining thin plates, heavy workpieces, long objects, and low strength fragile objects.

従来より、ワークを加工工程中に治具などの固定台に動かないように仮止め、固定し、加工工程の終了後にワークを固定台より取り外し可能な固定剤が知られている（例えば、特許文献１参照）。   Conventionally, a fixing agent is known in which a workpiece is temporarily fixed and fixed so as not to move to a fixture or other fixture during the machining process, and the workpiece can be removed from the fixture after the machining process is completed (for example, a patent) Reference 1).

このような固定剤の性質として、例えば、融点が室温より高い固定剤を用いるときには、ホットプレートなどで融点以上の温度に加熱されている固定台面上に塗布された固定剤を融解状態として、その上にワークを密着させた上で、固定台およびワークをドライヤーなど（冷風）で冷却することにより、固定剤を凝固させてこれによりワークを固定台に固定する方法が採られる。そして、ワークを固定した固定台を加工機テーブルへ移動して、ここで機械加工が行われる。
特開平７−２２４２７０号公報 As a property of such a fixing agent, for example, when a fixing agent having a melting point higher than room temperature is used, the fixing agent applied on the surface of the fixing base heated to a temperature higher than the melting point by a hot plate or the like is set in a molten state. A method is used in which the work is brought into close contact with the work piece, and then the fixing base and the work are cooled with a dryer or the like (cold air) to solidify the fixing agent, thereby fixing the work to the fixing base. And the fixed base which fixed the workpiece | work is moved to a processing machine table, and machining is performed here.
JP-A-7-224270

上記従来技術において、固定台の加熱・冷却手段としてホットプレートやドライヤーなどを用いる場合は、面積が大きいワーク、重いワークあるいは長尺物のワークなどに対して固定台も大型となるため、ポットプレート上への固定台の移動が困難になり、さらに、大型の固定台の大きな熱容量のため、加熱・冷却に要する時間が長くなるという問題がある。   In the above prior art, when a hot plate or a dryer is used as a heating / cooling means for the fixing base, the fixing base becomes large for a work having a large area, a heavy work or a long work, etc. There is a problem that it becomes difficult to move the fixed base upward, and that the time required for heating and cooling becomes long due to the large heat capacity of the large fixed base.

本発明は、上記点に鑑み、固定台を移動させずに加熱および冷却し、これにより固定台上でワークを固定する固定剤を融解および凝固する時間を短くすることを目的とする。   In view of the above points, an object of the present invention is to shorten the time for melting and solidifying the fixing agent for fixing the work on the fixing table by heating and cooling without moving the fixing table.

上記目的を達成するため、請求項１に記載の発明では、加熱工程において加熱手段（４）により加熱された固定台（１）上に融解状態の固定剤（６、６ａ）を介してワーク（５）が載置されており、冷却工程において固定台、固定剤およびワークを冷却することにより固定剤を凝固してワークを固定台に固定するワーク固定方法であって、
固定台の底面（１ｂ）には溝（１１）が形成されており、
加熱工程では、固定台の底面（１ｂ）が断熱シート（３）に接する状態で固定台が加工機テーブル（２）上に断熱シートを介して載置され、加熱手段により固定台が固定剤の融点以上の温度に加熱されることを特徴とする。 In order to achieve the above-mentioned object, in the invention described in claim 1, the workpiece ( 5) is a work fixing method in which the fixing agent is solidified by cooling the fixing base, the fixing agent and the work in the cooling step, and the work is fixed to the fixing base.
A groove (11) is formed on the bottom surface (1b) of the fixed base,
In the heating step, the fixing table is placed on the processing machine table (2) via the heat insulating sheet with the bottom surface (1b) of the fixing table being in contact with the heat insulating sheet (3), and the fixing table is fixed by the heating means. It is characterized by being heated to a temperature above its melting point.

この発明によれば、加工機テーブルの上に予め断熱シートを介して固定台を置いておき、この状態で固定台を加熱手段で加熱する。すなわち、断熱シートにより加工機テーブルと固定台との間の熱伝導が阻止されるので、固定台の加熱効率および冷却効率を高めることができ、加熱時間および冷却時間をともに短縮することができる。
特に、請求項１に記載の発明では、固定台の底面（１ｂ）に溝（１１）を形成しておくことにより、固定台と断熱シートとの接触面積が溝の開口部分で減少するので、固定台と加工機テーブルとの熱伝導量をさらに小さくすることができる。 According to this invention, the fixing base is previously placed on the processing machine table via the heat insulating sheet, and the fixing base is heated by the heating means in this state. That is, since heat conduction between the processing machine table and the fixing table is blocked by the heat insulating sheet, the heating efficiency and cooling efficiency of the fixing table can be increased, and both the heating time and the cooling time can be shortened.
In particular, in the invention according to claim 1, by forming the groove (11) on the bottom surface (1b) of the fixing base, the contact area between the fixing base and the heat insulating sheet decreases at the opening portion of the groove. The amount of heat conduction between the fixed base and the processing machine table can be further reduced.

また、加工機テーブルの上で、ワークの固定台への固定作業を行うことができるので、固定台の移動を不要にし、大型の固定台でもワークの固定作業を容易に行うことができる。   In addition, since the work can be fixed to the fixing table on the processing machine table, the movement of the fixing table becomes unnecessary, and the work can be fixed easily even with a large fixing table.

なお、加熱手段は、請求項２に記載のように、固定台に直接貼付されるシリコンラバーヒータ（４）を用いることにより、固定台を移動することなく固定台を加熱することができる。   In addition, a heating means can heat a fixed base, without moving a fixed base by using the silicon rubber heater (4) directly affixed to a fixed base, as described in Claim 2.

さらに、請求項３に記載の発明のように、冷却工程においては、固定台は断熱シートにより加工機テーブルとの間で熱伝導が阻止された状態で、溝（１１）に冷却水（７ａ）を流通させることにより、固定台の冷却を促進して冷却時間を短縮することができる。
Further, as in the invention according to claim 3 , in the cooling step, the fixing base is cooled in the groove (11) with the cooling water (7a) in a state where heat conduction is blocked between the fixing base and the processing machine table. By circulating, the cooling of the fixed base can be promoted and the cooling time can be shortened.

なお、上記各手段の括弧内の符号は、後述する実施形態に記載の具体的手段との対応関係を示すものである。   In addition, the code | symbol in the bracket | parenthesis of each said means shows the correspondence with the specific means as described in embodiment mentioned later.

（第１実施形態）
以下、本発明の第１実施形態のワークの固定方法および加工手順について図１に基づいて説明する。なお、図１において、加工機の本体等は省略している。 (First embodiment)
Hereinafter, a workpiece fixing method and a machining procedure according to a first embodiment of the present invention will be described with reference to FIG. In FIG. 1, the main body of the processing machine is omitted.

本第１実施形態で用いる固定台１は、磁石にくっつくステンレス材SUS４４０、縦４００ｍｍ×横２００ｍｍ×厚さ１５ｍｍで、ワーク５を固定するための上面（ワーク固定面）１ａには、開口幅３ｍｍ×深さ０．５ｍｍの断面が逆三角形の固定剤用溝１０が、碁盤目状に形成されている。すなわち、この固定剤用溝１０には、後述する固定剤６としての融点７５℃のパラフィンが融解状態で流動する。   The fixing base 1 used in the first embodiment is made of stainless steel SUS440, which is attached to a magnet, 400 mm long × 200 mm wide × 15 mm thick, and an upper surface (work fixing surface) 1a for fixing the work 5 has an opening width of 3 mm. X Grooves for fixing agent 10 having a cross section of an inverted triangle having a depth of 0.5 mm are formed in a grid pattern. That is, paraffin having a melting point of 75 ° C. as a fixing agent 6 to be described later flows in the fixing agent groove 10 in a molten state.

固定台１の底面１ｂには、複数の冷却用液体通路溝（幅１０ｍｍ×深さ５ｍｍ、矩形断面）１１が底面の一辺から対向する他の辺まで貫通するよう、互いに平行に形成されており、これらの溝に冷却用液体７ａを流通させることにより、効率的に固定台１を冷却可能にしている。   A plurality of cooling liquid passage grooves (width 10 mm × depth 5 mm, rectangular cross section) 11 are formed on the bottom surface 1 b of the fixed base 1 in parallel with each other so as to penetrate from one side of the bottom surface to the opposite side. By allowing the cooling liquid 7a to flow through these grooves, the fixing base 1 can be efficiently cooled.

このような固定台１を、加工機としての研削盤の電磁チャック式のテーブル２上に敷かれたシリコンゴム製の断熱シート３に、底面１ｂが接するように載置される。これにより、固定台１と熱容量の大きい研削盤テーブル２との間の熱伝導が阻止される。また、固定台１の底面１ｂに形成されている冷却用液体通路溝１１は、断熱シート３との間で冷却用液体通路を構成している。この冷却用液体通路溝１１は、研削盤テーブル２と固定台１との熱伝導を阻止する機能も備えている。   Such a fixing table 1 is placed so that the bottom surface 1b is in contact with a heat insulating sheet 3 made of silicon rubber laid on an electromagnetic chuck table 2 of a grinding machine as a processing machine. Thereby, heat conduction between the fixed base 1 and the grinding machine table 2 having a large heat capacity is prevented. Further, the cooling liquid passage groove 11 formed on the bottom surface 1 b of the fixed base 1 constitutes a cooling liquid passage with the heat insulating sheet 3. The cooling liquid passage groove 11 also has a function of preventing heat conduction between the grinder table 2 and the fixed base 1.

加熱工程として、固定台１の上面１ａには、磁石式のシリコンラバーヒータ４が貼付されており、外部電源（図示せず）によりシリコンラバーヒータ４が加熱され、これにより固定台１の温度を固定剤６の融点（７５℃）より高い温度（８５℃）まで上昇させる。なお、上記のように、固定台１は、断熱シート３により研削盤テーブル２との熱伝導が阻止されているので、シリコンラバーヒータ４による加熱で、温度上昇が早く進み、加熱時間を短くすることができる（図１（ａ））。   As a heating process, a magnet type silicon rubber heater 4 is affixed to the upper surface 1a of the fixing base 1, and the silicon rubber heater 4 is heated by an external power source (not shown), whereby the temperature of the fixing base 1 is increased. The temperature is raised to a temperature (85 ° C.) higher than the melting point (75 ° C.) of the fixing agent 6. As described above, since the heat conduction between the fixing base 1 and the grinder table 2 is blocked by the heat insulating sheet 3, the temperature rises rapidly by heating with the silicon rubber heater 4, and the heating time is shortened. (FIG. 1 (a)).

固定台１の加熱後、シリコンラバーヒータ４を固定台１より取り外し、同じ上面１ａ上に面積の大きいワーク５を置く。ワーク５は、縦３００ｍｍ×横１５０ｍｍ×厚さ１．５ｍｍのステンレス板である。   After the fixing table 1 is heated, the silicon rubber heater 4 is removed from the fixing table 1 and a workpiece 5 having a large area is placed on the same upper surface 1a. The workpiece 5 is a stainless steel plate having a length of 300 mm, a width of 150 mm, and a thickness of 1.5 mm.

そして、図１（ｂ）に示すように、固体状のパラフィンである固定剤６を、その融点以上の温度に加熱された固定台１の上面１ａの固定剤用溝１０にすり付けて融解させる。または、別に固定剤６を加熱して液体状態にしておき、この液体状態の固定剤６を固定剤用溝１０に流し込んでもよい。   Then, as shown in FIG. 1B, the fixing agent 6 which is solid paraffin is rubbed and melted in the fixing agent groove 10 on the upper surface 1a of the fixing base 1 heated to a temperature equal to or higher than the melting point thereof. . Alternatively, the fixing agent 6 may be separately heated to be in a liquid state, and the liquid fixing agent 6 may be poured into the fixing agent groove 10.

融解状態の固定剤６は、毛管現象により固定剤用溝１０に優先的に流動し、この固定剤用溝１０中の固定剤６によりワーク５が固定台１の上面１ａと隙間ゼロで密着する。   The melted fixing agent 6 flows preferentially into the fixing agent groove 10 by capillary action, and the workpiece 5 is brought into close contact with the upper surface 1a of the fixing table 1 with zero gap by the fixing agent 6 in the fixing agent groove 10. .

この状態で、冷却工程として、加工用冷却水供給口７を固定台１の底面１ｂに接近させて、加工用冷却水７ａを冷却用液体通路溝１１に流すことにより、固定台１を冷却する（図１（ｃ））。こうして、固定剤用溝１０を満たしていた固定剤６は融点以下の温度に冷却されて凝固し、これにより面積の大きいステンレス板ワーク５を固定台１に固定する。   In this state, as the cooling process, the cooling water supply port 7 is brought close to the bottom surface 1b of the fixing base 1, and the fixing water 1 is cooled by flowing the processing cooling water 7a through the cooling liquid passage groove 11. (FIG. 1 (c)). Thus, the fixing agent 6 filling the fixing agent groove 10 is cooled to a temperature equal to or lower than the melting point and solidifies, whereby the stainless plate workpiece 5 having a large area is fixed to the fixing table 1.

このようにして、面積の大きなワーク５が載った固定台１を移動させることなく、急速加熱、急速冷却が可能となる。   In this way, rapid heating and rapid cooling are possible without moving the fixed base 1 on which the workpiece 5 having a large area is placed.

固定剤が凝固、固化した後に、固定台１の底面１ｂより断熱シートを取り外し、固定台１を直接研削盤テーブル２上において、電磁チャックにより固定台１を固定して加工用冷却水７ａを掛けながら回転砥石９により研削加工が行われる（図１（ｄ））。   After the fixing agent has solidified and solidified, the heat insulating sheet is removed from the bottom surface 1b of the fixing table 1, and the fixing table 1 is directly fixed on the grinding machine table 2 by fixing the fixing table 1 with an electromagnetic chuck, and the processing cooling water 7a is applied. However, grinding is performed by the rotating grindstone 9 (FIG. 1 (d)).

加工後は、温水供給口８より固定剤６の融点より高い９０℃程度の温水を、ワーク５および固定台１の上面１ａに掛けることにより、ワーク５を固定していた固定剤用溝１０中の固定剤６を再融解させることにより、ワーク５を固定台１より容易に取り外すことができる。   After processing, hot water of about 90 ° C., which is higher than the melting point of the fixing agent 6, is applied to the workpiece 5 and the upper surface 1 a of the fixing base 1 from the hot water supply port 8, thereby fixing the workpiece 5 in the fixing agent groove 10. The work 5 can be easily removed from the fixing base 1 by remelting the fixing agent 6.

（第２実施形態）
次に、本発明の第２実施形態のワークの固定方法および加工手順について図２に基づいて説明する。なお、本第２実施形態においては、上記第１実施形態と同じ構成部分については、説明を簡略化し、異なる点を中心に説明する。 (Second Embodiment)
Next, a workpiece fixing method and a machining procedure according to the second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the same components as those in the first embodiment will be described briefly and different points will be mainly described.

本第２実施形態で用いる固定台１は、上記第１実施形態と同様、磁石にくっつくステンレス材SUS４４０、縦４００ｍｍ×横２００ｍｍ×厚さ１５ｍｍであるが、ワーク５を固定するための上面（ワーク固定面）１ａは、第１実施形態とは異なり、固定剤用溝は形成されておらず、フラットで、面粗度２．４Ｒｚに仕上げられている。したがって、本第２実施形態では、固定剤６としての融点７５℃のパラフィンは、後述するように、融解状態では、ワーク５と固定台１のフラットな上面１ａとの隙間に介在することとなる。   As in the first embodiment, the fixing base 1 used in the second embodiment is made of stainless steel SUS440, which is attached to a magnet, 400 mm long × 200 mm wide × 15 mm thick, but the upper surface for fixing the work 5 (workpiece Unlike the first embodiment, the fixing surface 1a is not formed with a fixing agent groove and is flat and finished with a surface roughness of 2.4 Rz. Therefore, in the second embodiment, the paraffin having a melting point of 75 ° C. as the fixing agent 6 is interposed in the gap between the workpiece 5 and the flat upper surface 1a of the fixing base 1 in the molten state, as will be described later. .

なお、固定台１の底面１ｂには、第１実施形態と同様の複数の冷却用液体通路溝１１が形成されている。   A plurality of cooling liquid passage grooves 11 similar to those of the first embodiment are formed on the bottom surface 1b of the fixed base 1.

このような固定台１を、図２（ａ）に示すように、第１実施形態と同様、研削盤の電磁チャック式のテーブル２上に敷かれたシリコンゴム製の断熱シート３に、底面１ｂが接するように載置される。また、固定台１の上面１ａには、磁石式のシリコンラバーヒータ４が貼付されており、このシリコンラバーヒータ４により固定台１の温度を固定剤６の融点（７５℃）より高い温度（９０℃）まで上昇させる。   As shown in FIG. 2A, such a fixing base 1 is provided on a heat insulating sheet 3 made of silicon rubber laid on an electromagnetic chuck type table 2 of a grinding machine, as in the first embodiment, on a bottom surface 1b. Is placed in contact with each other. A magnet-type silicon rubber heater 4 is attached to the upper surface 1 a of the fixing base 1, and the temperature of the fixing base 1 is higher than the melting point (75 ° C.) (90 ° C.) of the fixing agent 6 by this silicon rubber heater 4. C.).

本第２実施形態では、図２（ｂ）に示すように、固定台１の加熱後、シリコンラバーヒータ４を固定台１より取り外し、その後、固体状の固定剤６を高温の固定台１の上面１ａにこすり付けて塗布し、上面１ａを融解状態の固定剤６ａで覆う。   In the second embodiment, as shown in FIG. 2 (b), after the fixing base 1 is heated, the silicon rubber heater 4 is removed from the fixing base 1, and then the solid fixing agent 6 is removed from the high-temperature fixing base 1. The upper surface 1a is rubbed and applied, and the upper surface 1a is covered with a melted fixing agent 6a.

融解状態の固定剤６ａ上に、ワーク５としての縦１５０ｍｍ×横１５０ｍｍ×高さ２００ｍｍのアルミ製ブロックを置く。融解状態の固定剤６ａは、ワーク５の重みによりワーク５と固定台１の上面１ａとの間より排除されつつ、この界面に約６μｍの薄膜となって介在する。残りの固定剤６ｂはワーク５の端部に堆積して盛り上がる。このようにして、ワーク５と固定台１とが密着状態となる。   An aluminum block having a length of 150 mm, a width of 150 mm, and a height of 200 mm as the work 5 is placed on the fixing agent 6a in a molten state. The fixing agent 6a in the melted state is excluded from between the workpiece 5 and the upper surface 1a of the fixing table 1 due to the weight of the workpiece 5, and is interposed as a thin film of about 6 μm at this interface. The remaining fixing agent 6b accumulates on the end of the workpiece 5 and rises. In this way, the workpiece 5 and the fixed base 1 are in close contact with each other.

この状態で、第１実施形態と同様、加工用冷却水供給口７を固定台１の底面１ｂに接近させて、加工用冷却水７ａを冷却用液体通路溝１１に流すことにより、固定台１を冷却する（図１（ｃ））。   In this state, as in the first embodiment, the processing cooling water supply port 7 is brought close to the bottom surface 1b of the fixing base 1 and the processing cooling water 7a is caused to flow through the cooling liquid passage groove 11 to thereby fix the fixing base 1. Is cooled (FIG. 1 (c)).

こうして、固定台１とワーク５との間の界面の薄膜状固定剤６ａは融点以下の温度に冷却されて凝固し、これによりワーク５を固定台１に固定する。   In this way, the thin film-like fixing agent 6a at the interface between the fixing base 1 and the work 5 is cooled to a temperature below the melting point and solidifies, thereby fixing the work 5 to the fixing base 1.

このようにして、ブロック状の重量の大きいワーク５が載った固定台１を移動させることなく、急速加熱、急速冷却が可能となる。   In this way, rapid heating and rapid cooling are possible without moving the fixed base 1 on which the block-shaped workpiece 5 having a large weight is placed.

固定剤が凝固、固化した後に、第１実施形態と同様、固定台１の底面１ｂより断熱シートを取り外し、固定台１を直接研削盤テーブル２上において、電磁チャックにより固定台１を固定して加工用冷却水７ａを掛けながら回転砥石９により研削加工が行われる（図２（ｄ））。   After the fixing agent is solidified and solidified, as in the first embodiment, the heat insulating sheet is removed from the bottom surface 1b of the fixing base 1, and the fixing base 1 is directly fixed on the grinding machine table 2 by the electromagnetic chuck. Grinding is performed by the rotating grindstone 9 while applying the cooling water 7a for processing (FIG. 2 (d)).

加工後は、温水供給口８より固定剤６の融点より高い９０℃程度の温水を、ワーク５および固定台１の上面１ａに掛けることにより、ワーク５を固定していた固定剤６ａ、６ｂを再融解させることにより、ワーク５を固定台１より容易に取り外すことができる。   After processing, hot water of about 90 ° C., which is higher than the melting point of the fixing agent 6, is applied to the workpiece 5 and the upper surface 1 a of the fixing base 1 from the hot water supply port 8, thereby fixing the fixing agents 6 a and 6 b that have fixed the workpiece 5. By remelting, the workpiece 5 can be easily removed from the fixed base 1.
