detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in FIG. 1 , FIG. 2 and FIG. 3 , the tapping machine of this embodiment includes a mounting table 1 , a cross arm 3 , a tap mounting seat 6 and a driving motor 4 . One end of the cross arm 3 is installed on the mounting platform 1, the tap mounting seat 6 is fixed on the other end of the cross arm 3, the tap mounting seat 6 is equipped with a tap 8, and the driving motor 4 is installed on the tap mounting seat 6. The driving motor 4 Used to drive the screw tap 8 to rotate. In a preferred design, the driving motor 4 is designed as a servo motor. For ease of use, a handle is fixed on the tap mounting base 6 .

The cross arm 3 includes a first connecting arm 31 and a second connecting arm 32 . A column-shaped fixing base 2 is fixed on the installation platform 1 , and one end of the first connecting arm 31 is hingedly connected with the fixing base 2 .
