Abstract

The invention relates to a flexible positioning wear-less vibrating sand filling device for fuse protectors. The flexible positioning wear-less vibrating sand filling device comprises a vertical variable-frequency vibrator, a support, a prepressed track type sand filling valve component, a flexible compression positioning component, a flexible sand filling nozzle component, a sand filling cylinder, a sand filling sensor component, a multi-station turn plate and a vibrator power switch. The vertical variable-frequency vibrator is arranged on the multi-station turn plate, the support is arranged on the vertical variable-frequency vibrator, the prepressed track type sand filling valve component, the flexible compression positioning component and the flexible sand filling nozzle component are arranged on a cylinder movable seat of the sand filling cylinder, the cylinder movable seat is arranged on the support, the sand filling sensor component is arranged on the vertical variable-frequency vibrator and corresponds to the flexible sand filling nozzle component, and fuse protectors are arranged on a fuse protector support on the vertical variable-frequency vibrator. Compared with the prior art, the flexible positioning wear-less vibrating sand filling device for the fuse protectors has the advantages of small wear to workpieces, rapidness, convenience, high efficiency and the like.

Description

technical field [0001] The invention relates to a sand filling device for a fuse, in particular to a sand filling device for a flexible positioning non-wearing vibration fuse. Background technique [0002] Domestic low-voltage electrical appliance companies adopt manual sand filling for fuses, which is low in efficiency and uneven in sand filling, and it is easy to make the compactness fail to meet the predetermined requirements. However, mechanical sand filling machines commonly used abroad have complex structures and are easy to wear The surface of the fuse is easy to cause waste of cost. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects in the prior art and provide a sand filling device with accurate positioning, low workpiece wear, quick and efficient flexible positioning and no wear vibration fuse. [0004] The purpose of the present invention can be achieved through the following technical solutions: a...
