Embodiment Construction

[0033] Such as figure 1 As shown, a nut gun with automatic focus includes a gun body 1 with a handle, a motor is arranged in the gun body 1, a gun head 4 is provided at the front end of the gun body 1, and a circular ring is connected between the gun body 1 and the gun head 4. barrel 2. The handle is provided with a switch to control the forward or reverse rotation of the motor in the gun body 1. When the motor rotates forward, the gun head 4 focuses and installs the nut. When the motor reverses, the gun head 4 reverses and withdraws from the nut.

[0034] Such as figure 2 As shown, the inner wall of the gun head 4 is embedded with a limited marble 3 for pre-tightening the nut so that the nut is difficult to drop from the gun head 4 .

[0035] The cylinder 2 is provided with a connecting sleeve 5, a clutch device 6 and a gear mechanism 7. The clutch device 6 includes a clutch lever 601, a first clutch groove 602, and a second clutch groove 603. The gear mechanism 7 includes...

Abstract

The invention discloses an auto-focusing nut gun, which comprises a gun body with a handle, wherein the gun body is connected with a gun head through a wheel axle of a third driven wheel. A cylinder is arranged at the front end of the gun body and is internally provided with a gear mechanism with a clutch device. The gear mechanism comprises a first gear set and a second gear set. The first gear set comprises a first driving wheel and a first driven wheel. The second gear set comprises a second driving wheel, a second driven wheel and a third driven wheel. The auto-focusing nut gun provided by the invention integrates mechanical transmission with motor control effectively, so that the gun head can be reversely focused by means of combined transmission of the gear sets to ensure that the nut is identical to the aim point of the bolt so as to avoid thread slippery. The auto-focusing nut gun is combined with the clutch device, the sleeve and the like, so that the gun head can return forward. A limiting elastic ball is additionally arranged at the gun head to pre-fasten the nut. The auto-focusing nut gun is small, compact in structure, simple to operate and safe to use, and not only reduces the loss of parts, improves the quality of product, but also improves the work efficiency and is beneficial for line production.

Description

technical field [0001] The invention relates to a nut gun, in particular to an automatic focusing nut gun. Background technique [0002] At present, on the production lines of automobile welding and assembly, there are many works that need to install nuts and bolts. In order to improve work efficiency, nut guns are usually used for riveting operations. Nut guns are mainly divided into single-handle nut guns and double-handle nut guns according to different handles, and the single-handle nut gun is more widely used. When using the nut gun, the nut must be screwed on the bolt of the gun head first, and the bolt of the gun head should be rotated counterclockwise after riveting, so that the nut gun can withdraw from the riveted nut. The existing nut guns are mainly provided with two types of switches. One switch is used to rivet the nut on the gun head to the workpiece, and the other switch is used to reverse the gun head and withdraw from the nut. The defects are: two The seq...
