I液压夹具 我厂在加工内圆磨床附件之砂轮接头时,因外圆与 内推拔之要求较高(同心度在0.01公厘)。因此就有设计 特种精密夹具之需要。开始就决定 设计了两种磨夹具:一为机械涨紧式夹具;一种是周勤之同志参■了苏联塑料夹具而设计的液压夹具(协作者有王隆西同志),其结构如图1。 I hydraulic fixture I plant grinding wheel grinder attachment attachment, due to the requirements of the cylindrical and push the higher (concentricity of 0.01 mm). Therefore, there is a need to design special precision clamps. The beginning of the decision to design two kinds of grinding fixture: a mechanical clamping fixture; one is Comrade Zhou Qin Participation ■ the Soviet Union plastic fixture designed hydraulic fixture (collaborator Wang Longxi comrades), the structure shown in Figure 1.
