An automatic riveting machine for the assembly of the fan shaft sleeve and the middle plate

Abstract

An automatic riveting machine for draught fan shaft sleeve and middle disc assembling comprises a rack. A workbench is arranged above the rack. An index plate is arranged on the workbench. A vibrationdisc, a pneumatic indexing mechanism, a pressing-rivet mechanism and a tooth upsetting mechanism are arranged on the periphery of the workbench. The index plate is arranged at the center of the workbench and provided with a plurality of loading tables evenly distributed along the circumference. The outer ring of the index plate is provided with a shaft sleeve grabbing mechanism, a middle disc grabbing mechanism corresponding to the pneumatic indexing mechanism in position, and a discharging mechanism. The pressing-rivet mechanism is provided with pressing-rivet dies corresponding to the loading tables in position. The tooth upsetting mechanism is provided with tooth upsetting dies corresponding to the loading tables in position. According to the automatic riveting machine for draught fanshaft sleeve and middle disc assembling, all procedures in the riveting process can be finished on one device, errors caused by manual assembling can be avoided, the riveting quality is guaranteed, and the efficient riveting efficiency can be constantly kept.

Description

technical field [0001] The invention relates to an automatic riveting machine, in particular to an automatic riveting machine used for assembling a fan shaft sleeve and a center plate. Background technique [0002] The riveting process of the fan shaft sleeve and the center plate needs to go through three steps of assembly, pressure riveting and upsetting teeth. The traditional riveting process requires multiple equipment. It is necessary to use upsetting equipment, and when the product that has been processed in one process is transferred to another equipment, it will consume a lot of time, resulting in low riveting efficiency, and purchasing multiple equipment for riveting will lead to riveting The cost increases, which leads to an increase in the overall cost of the fan, and it is easy to make mistakes when installing the fan shaft sleeve and the center plate manually, resulting in poor assembly quality, especially a screw hole on the shaft sleeve needs to face the balanc...
