Embodiment Construction

[0019] The invention provides a novel electromagnetic riveting gun buffer device which transforms the axial compression into a certain amount of circumferential compression through the inclined slider structure. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the invention.

[0020] Such as figure 1 Shown, the structure diagram of traditional hand-held electromagnetic riveting gun, it is made up of capacitor group 14, handle 15, buffer 16, resilient body 17, primary coil 18, secondary coil 19, modulator 20, rivet 21, top iron 22 etc. composition, its working process is as follows:

[0021] 1) The capacitor bank 14 is discharged through the coil, and an eddy current repulsion force is generated between the primary coil 18 ...

Abstract

The invention relates to a vibration reduction and isolation system for a handheld electromagnetic riveter. The system comprises four radial spring buffering units and one axial spring buffering unit. The system is characterized in that each radial spring buffering unit comprises a radial spring (5) and a pressing block (9). A pressing block groove (8) is formed in each pressing block (9), and the radial springs (5) are arranged in the pressing block grooves (8) to be positioned and limited. A central spring (10) is mounted in a sliding block groove (13) in a sliding block (11). According to the system, various buffering units such as a buffering pad, springs and the like, compared with hydraulic and liquid-gas buffering, the structure is simple, and problems are easy to solve. The system is comfortable to be used by operators, capable of improving the work efficiency and good for the completion of work.

Description

Technical field: [0001] The invention relates to electromagnetic riveting gun technology, in particular to a shock-absorbing and vibration-isolation system for a hand-held electromagnetic riveting gun. Background technique: [0002] Electromagnetic riveting is a riveting process developed to solve the riveting of large-diameter rivets and rivets of difficult-to-form materials, and has been widely used in the aerospace field. my country has also successfully developed fixed and portable electromagnetic riveting guns. The fixed riveting gun has certain limitations in practical application due to the restriction on the openness of the structure; the portable electromagnetic riveting gun is small in size and easy to use, but the existing riveting gun will generate a large recoil force when used. There are certain restrictions in engineering applications. To reduce the recoil force, on the one hand, the weight of the resilient body can be increased, but it is not conducive to ha...
