BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 is a structure diagram of the pipe joint part.

[0012] Figure 2 is a general structure diagram.

[0013] Figure 3 is a base.

[0014] In the figure: 1 positioning bolt, 2 fastening bolt, 3 base, 4 pipe joint blank. DETAILED DESCRIPTION

[0015] The technical scheme of the utility model will be further explained below according to the drawings.

[0016] A machining step of the quick clamping tool for numerically controlled turning of the pipe joint part:

[0017] 1) clamping the base 2 on the chuck of the numerically controlled lathe;

[0018] 2) screwing the positioning bolt 1 into the base 2;

[0019] 3) putting the pipe joint blank into the groove of the boss, with the bottom surface contacting the groove bottom and the side surface respectively positioning with one surface of the groove and the end surface of the positioning bolt 1;
