Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

As shown in fig. 1-3, the multi-surface one-time clamping forming tool of this embodiment includes a base, two bolts 3, and three positioning pins 4, the base includes a connecting body 1 and a flange 2, the flange 2 is fixed on the lower end surface of the connecting body 1, the connecting body 1 is cylindrical, in order to mill the shape of a part 12 and meet the requirement of feeding during machining, a piece of boss 5 is integrally formed on the upper end surface of the connecting body 1, the boss 5 matches with the part 12 in shape, when the tool is positioned, the tool cannot be fixed and positioned only by threads, the alignment error of the threads cannot ensure the machining precision of the part 12, therefore, the threads can only be used for fixing the part 12, in addition, pins are needed for positioning, therefore, two bolt holes 7 and three positioning pin holes 6 are provided on the boss 5 of this embodiment, after the part 12 is placed on the boss 5, the two bolts 3 pass through the part 12 and are in threaded connection with the two, and pass part 12 and insert locating pin hole 6 with three locating pin 4, the quantity of locating pin 4 and supporting locating pin hole 6 to and bolt 3 and supporting bolt hole 7 can be decided according to the demand, as long as guarantee locating pin 4 and bolt 3 and use jointly for fixed and location can.
