Rivet pulling mechanism and rivet pulling method

Abstract

The invention discloses a rivet pulling mechanism and a rivet pulling method that the rivet pulling mechanism is adopted to carry out rivet pulling deformation on a blind nut. The rivet pulling mechanism comprises a compressing base, a thrust base and a pulling rod. The compressing base is used for abutting against the blind nut, the compressing base and the thrust base can be rotatably sleeved on the pulling rod around the pulling rod, the thrust base is in threaded connection with the compressing base, a first external thread matched with a first internal thread of the blind nut is arranged at one end, close to the compressing base, of the pulling rod, an axial limiting structure for axially limiting the thrust base is arranged at the other end, close to the thrust base, of the pulling rod, and the thrust base and the axial limiting structure can rotate relatively. The rivet pulling mechanism is simple in structure and low in cost, the rivet pulling method is easy and convenient to practice, needed operation space is very small when the rivet pulling deformation is carried out on the blind nut, and the working demand for small space rivet pulling is well met.

Description

technical field [0001] The invention belongs to the field of hardware tools and the use thereof, in particular to a novel riveting mechanism and a riveting method. Background technique [0002] Blind rivet nuts, also known as rivet nuts or pull caps, are used in the fastening field of various metal sheet or pipe manufacturing industries. They are developed to solve the shortcomings of metal sheet and thin tube welding nuts that are easy to melt and tap internal threads that are easy to slip. In the process of riveting, there is no need to tap internal threads, no welding nuts, and at the same time, it has the advantages of high riveting efficiency. It is widely used in automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture and decoration. And the assembly of light industrial products. [0003] When the space where the fastening connection needs to be fastened is narrow or the use of the riveting machine is limited, so that the riveting c...

AI Technical Summary

Problems solved by technology

[0004] When the riveting gun is used to rivet the rivet nut, although the operation is simple and the connection is tight, the use of the riveting gun may still be restricted when the riveting connection is performed in some special positions where the allowable operating space is narrower. limit

For example, when repairing or replacing the blind rivet nuts on the assembled equipment, the operating space allowed by the equipment is generally very narrow. At this time, the equipment needs to be disassembled for easy maintenance, which not only costs a lot but also wastes time
