High-precision nut cap rotary riveting device

Abstract

The invention provides a high-precision nut cap rotary riveting device. The high-precision nut cap rotary riveting device is used for rotary riveting assembly of a nut and a nut cap in a multi-stationnut riveting press. The rotary riveting device comprises a rotary motor, a rotary riveting lifting air cylinder, a rotary riveting fixing seat, a connecting shaft and a rotary riveting combined head,wherein the rotary motor is arranged on the rotary riveting lifting air cylinder, the rotary motor is connected with the connecting shaft, the connecting shaft penetrates through the rotary rivetinglifting air cylinder, the rotary riveting lifting air cylinder is arranged on the rotary riveting fixing seat, the rotary riveting combined head is connected with the connecting shaft, the rotary riveting combined head comprises two rivet joints and a fixed disc, the two rivet joints are connected with the fixed disc through bearings and fixing shafts, the fixed disc is connected with the connecting shaft, and the outer edges of the ends, facing the nut cap, of the rivet joints are inclined faces. The high-precision nut cap rotary riveting device is more efficient, the part size is stabler, and the part appearance is more attractive.

Description

technical field [0001] The invention relates to a rotary riveting device, in particular to a high-precision full-automatic multi-station multi-functional tire hub nut cap rotary riveting device for lock nuts with painted stainless steel surfaces. Background technique [0002] A nut is a part that can tightly connect mechanical equipment. It is usually used in conjunction with a bolt to achieve the purpose of fastening the part, that is, by passing the bolt through the hole provided on the part, and connecting the nut to the other end of the bolt. To fasten the parts, the nuts used in automobiles usually include the nut body and the annular protective cap integrated with the nut. At present, the riveting process of tires, wheel hub lock nuts or hexagonal nuts and hexagonal nut caps Among them, most of them have been executed with automatic equipment. For example, the company's patent application number 201910194085.4 high-precision multi-station nut riveting machine is one of...
