Abstract

The invention discloses a parallel mechanism based single drive one-translation two-rotation three-dimensional sand filling vibration-compaction machine. The machine comprises a fixed pedestal, a movable platform, a driving branch chain I and a driven branch chain II; the driving branch chain I and the driven branch chain II are respectively positioned at the left and right sides of the fixed pedestal; the two ends of the driving branch chain I are respectively connected to the fixed pedestal and the movable platform; the two ends of the driven branch chain II both are connected to the fixed pedestal; and the driven branch chain II is connected to the movable platform via a rotation pair R2. When a single drive is applied to the driving branch chain I, the movable platform can simultaneously carry out a three-dimensional vibration form of vertical vibration, deflection vibration and pitch vibration; the vibration-compaction machine has the characteristics of single input and multiple outputs, and is simple in structure, convenient in manufacturing and maintenance, energy-saving and reliable; through regulating a displacement drive on a moving pair, the vibration frequency and amplitude of the vibration platform can be changed; and by combining with a sand filling process, the fuse sand filling compactness is improved, and the fuse production efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical vibration, in particular to a sand filling vibrator with a fuse single-drive multi-dimensional vibration output. Background technique [0002] The fuse is a circuit protector with high segmentation capability. The fuse tube is filled with quartz sand as the arc extinguishing medium. When the short-circuit current passes, the arc is extinguished by the quartz sand and absorbs the arc energy. It has a strong arc extinguishing ability. , can greatly improve the electrical stability and thermal stability of the protected electrical equipment. The chemical composition, shape, particle size and other characteristics of quartz sand all have an impact on the arc extinguishing performance of the fuse. Studies have shown that the tightness of the quartz sand filling in the fuse package directly affects the segmentation ability of the fuse. The increase of the fuse can improve a series of action performance when t...
