Problems solved by technology

[0002] At present, when tapping some small-diameter holes in the workpiece, small electric drill tapping machines or manual tapping wrenches are mostly used. Accurate grasp, its use flexibility is low, and it is easy to cause the drill bit to break when the force is too large, while the conventional manual tapping wrench is inconvenient to operate, the work efficiency is low, and the tap is easy to shift

Embodiment Construction

[0013] A tapping device such as Figure 1~3 As shown, it includes a swivel body 10, and the swivel body 10 is connected with a tap 30 and a support rod 20. The tap 30 and the support rod 20 are reversely extended from the body of the swivel body 10 and arranged concentrically. The swivel body 10 and the screw tap 30 are fixedly connected in a detachable manner, and the swivel body 10 and the supporting rod 20 are rotationally fitted. During use, first screw tap 30 is installed and fixed on the swivel 10, then the screw tap 30 is vertically aimed at the hole on the workpiece to be tapped, one hand of the operator holds the supporting rod 20 to stabilize the tapping device, and the other Only hand pushes or rotates the swivel 10 to rotate around the support rod 20 to drive the screw tap 30 to rotate, thereby realizing tapping. Shifting causes screw tap 30 to break off, has guaranteed the reliability of tapping, and because the steady action of supporting bar 20, makes manual op...

Abstract

The invention discloses a tapping device. The tapping device comprises a rotary body. The rotary body is connected with a screw tap and a supporting rod. The screw tap and the supporting rod stretch reversely from a body of the rotary body and are concentrically arranged. The rotary body and the screw tap are detachably and fixedly connected, and the rotary body and the supporting rod are in running fit. When the tapping device is used, the screw tap is vertically aligned with a hole in a workpiece to be tapped, then, a user holds the supporting rod with one hand so as to stabilize the tapping device and pushes or rotates the rotary body with the other hand so as to allow the rotary body to rotate around the supporting rod, the screw tap is driven to rotate, and then tapping operation is achieved. The fixing performance of the tapping device is high in the tapping process through the supporting rod, deflection of the screw tap is avoided, tapping reliability is guaranteed, manual operation is convenient, and tapping efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of machining, in particular to a tapping device. Background technique [0002] At present, when tapping some small-diameter holes in the workpiece, small electric drill tapping machines or manual tapping wrenches are mostly used. Accurate grasp, its use flexibility is low, and it is easy to cause the drill bit to break when the force is too large, while the conventional manual tapping wrench is inconvenient to operate, the work efficiency is low, and the tap is easy to shift. Contents of the invention [0003] The purpose of the present invention is to provide a tapping device that is convenient for manual operation and convenient positioning. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a tapping device, characterized in that: it comprises a swivel body, on which a tap and a support rod are connected, and the tap and the support rod are reversed on the ...
