しかも、ベース部材2Aの上面に固定したボルト孔形成部材50及び座面形成部材60に基準座面54,63を形成するため、ベース部材2Aの上面の平面精度を高める必要がないから、ベース部材2Aの製作費を節減できる。しかも、基準座面54,63の全体の面積が小さいため、基準座面54,63をエアブローしてクリーニングする面積が小さく、エアブローが容易になる。
しかも、第1,第2基準部材10B,20Bの中央部に鉛直の第1のボルト挿通孔71,72を夫々形成し、第1のボルト挿通孔71,72に対応するベース部材2Bの部分に複数のボルト孔70を形成し、第1のボルト挿通孔71,72に対応するワークパレット3Bの部分に複数のボルト挿通孔73を形成し、ベース部材2Bの基準座面5Bの上にワークパレット3Bを載置し、複数のクランプ用ボルト4Bをボルト挿通孔73から第1,第2基準部材10B,20Bの第1のボルト挿通孔71,72を介してベース部材2Bのボルト孔70に夫々締結した。従って、クランプ用ボルト4Bを第1,第2基準部材10B,20Bを挿通させてベース部材2Bに直接締結して、ワークパレット3Bをベース部材2Bに位置決めして固定するので、第1,第2基準部材10B,20Bをベース部材2Bに対して最小限の固定力で固定可能となり、複数の取り付け用ボルト14,24の本数を低減させることができ、又は、取り付け用ボルトのサイズを小さくしてフランジ部を小径化でき、製作コストの節減を図ることができる。
しかも、ベース部材2Cの第1,第2基準部材10C,20Cの外側部分に1対のボルト孔75を形成し、この1対のボルト孔75に対応するワークパレット3Cの部分に1対のボルト挿通孔78を形成したので、第1,第2基準部材10C,20Cの上方に対応するワークパレット3Cの上面を、ワークを設置可能なスペースとすることができるので、より大型のワークをワークパレットに固定することができる。
図17に示すように、圧入手段80は、ボルト部材81と、第1環状係合部材30と略同じ直径のリング部材82とから構成されている。
図18に示すように、第1の取り外し手段83は、ボルト部材84と、環状係合部材30の内径より僅かに小径のプレート部材85と、断面矩形状のC形リング86とから構成されている。
図19に示すように、第2の取り外し手段87は、工具が係合可能な六角孔を有する複数の小径ボルト88と、これら複数の小径ボルト88が螺着可能な複数の小径ボルト孔89とから構成されている。
