在机床上精加工平的、中凹的大薄板类零件、薄壁零件以及铜、铝、硬质合金、塑料等非导磁材料的薄片工件时,可以采用真空吸力盘。真空吸力盘主要由真空泵组、真空罐、调压阀、电路切断器、换向阀、真空吸盘等部分组成(见图1)。在压缩空气供应方便时,也可用压缩空气为动力,推动特殊的活塞气缸形成真空(见图2)。真空泵组的作用是将密闭系统中的空气抽出,使之形成真空。泵是由电动机通过皮带传动装置带动
In the machine tool finishing flat, concave large thin-walled parts, thin-walled parts and copper, aluminum, cemented carbide, plastic and other non-magnetic material sheet workpiece, you can use vacuum suction disc. Vacuum suction disc mainly by the vacuum pump, vacuum tank, pressure regulator, circuit breaker, reversing valve, vacuum suction cup and other components (see Figure 1). In the compressed air supply is convenient, you can also use compressed air as a driving force to promote a special piston cylinder to form a vacuum (see Figure 2). Vacuum pump group is the role of the closed system to extract the air, so that the formation of a vacuum. The pump is driven by the motor through the belt drive
