[0002] Tapping is the process of producing internal threads by screwing a tap into a hole using a specific torque. Rigid tapping is also known as synchronous feed tapping.

[0003] However, in actual applications, most existing tapping mechanisms usually use forward and reverse cycle rotation to perform tapping operations, which can reduce the risk of the drill breaking. However, during the forward and reverse cycle rotation process, the drill can only tap one tubular mechanical part at a time. Therefore, the tapping efficiency is relatively low, which is not conducive to popularization and use.

[0004] Therefore, those skilled in the art provide a tapping mechanism for a tubular mechanical part to solve the problems raised in the above background technology. Utility Model Content

[0009] Preferably, both the front and rear ends of the support sleeve are threadedly connected with locking bolts.

[0010] Preferably, the rear end of the screw rod is fixedly connected to a transmission disc.

[0011] In summary, this application has the following beneficial technical effects:

[0012] 1. By setting up a tapping drill, two tubular mechanical parts that need to be tapped are placed on a fixed frame, the screw is turned to drive the pressure plate to squeeze and fix the placed tubular mechanical parts, and the position of the transmission block is turned to adjust the position of the screw rod so that the axis centers of the two tapping drills and the axis centers of the tubular mechanical parts are on the same horizontal line. The output shaft of the electric telescopic rod cooperates with the support sleeve and the support block to drive the dual-axis servo motor to move left and right in a circular motion. While moving, the two output shafts of the dual-axis servo motor simultaneously drive the two tapping drills to rotate forward and backward.
