Abstract

The invention provides an efficient electric nut gun head with long service life. The efficient electric nut gun head comprises a driving shaft connecting rod and a nut pull rod which are in transmission connection, wherein a rear sleeve sleeves the driving shaft connecting rod; a front sleeve sleeves the nut pull rod; the front sleeve is in positioning connection with the rear sleeve; the driving shaft connecting rod and the rear sleeve are in positioning fit through a positioning bearing; the nut pull rod and the front sleeve are in positioning fit through a plane bearing; and the driving shaft connecting rod is used for driving the nut pull rod to rotate when a nut gun operates. Compared with original multi-rod transmission, the efficient electric nut gun head with long service life is higher in stability; and moreover, the driving shaft connecting rod and the nut pull rod are separately positioned through the positioning bearing and the plane bearing, so that coaxiality of the nut pull rod and a driving shaft can be guaranteed, relative vibration in a rotating process is reduced, high-speed rotation is realized, working efficiency is improved, and the service life is relatively long.

Description

Technical field [0001] The present invention relates to the field of electric nut gun, and more particularly to an electric nut head that is efficient and long-lived. Background technique [0002] Rivet guns are commonly used in rivet-mounting tools, widely used in riveting processes such as construction, cars, ships, aircraft, electrical, furniture and other products. The existing rivet billets are in riveting, and the rivet rods that often replace different specifications are often replaced according to the usage. The rivet rod of the existing rivet rod and the joining method of the tie rod uses a threaded connection. When replacing the rivet rod, it is necessary to rotate multiple times to disassemble and assemble, more troublesome and time consuming, and the existing nut gun head needs Replace the tie rod, the nut head connection rod, etc., resulting in its inconvenience; the existing nut gun head is a multi-pole connection, because the transmission rod member is more, it is ...
