Contains xz theta triaxial adjustable suction-cup institutions, specific include a motor is responsible for the different location the location of the rotation, slide cylinder is responsible for x axis and z axis transverse, chuck institutions with rotating cylinder can rotate 180 ° at the same time.1. The agency on the z axis and its ingenious use of slippery course module, tolerance to eliminate suction head to breathe in different location, directly by the slippery course modules to compensate, very clever ideas, is worth using for reference.2. The agency can also adjust the elevation of the elevations, with the adjustment of the elevation bolt, and the organization and representative.The mechanism USES the combination of cylinder and motor, which can be adjusted by Angle and displacement, which is very representative.逐句翻译
