Use method of multifunctional machining tool

Abstract

The invention relates to a use method of a multifunctional machining tool. The method comprises the following steps that: 1, a locating plate and a locating disk are located through locating pins, and then bolts are used for fastening the locating plate and the locating disk; 2, the locating disk is installed on a three-jaw chuck of a machining center, and it is ensured that a first step surface and a second step surface on the locating plate face upward horizontally; 3, a cylindrical boss on a workblank piece is matched with a counter bore in the second step surface, and then a screw is used for fixing the workblank piece onto the locating plate through a counter bore in a base disk of the workblank piece; 4, the circumference of the base disk of the workblank piece is milled into a square shape, and then an arc surface is milled out of the bottom face of the base disk; 5, the locating disk is rotated by a certain angle, the arc surface is machined by drilling, inclined holes are formed by drilling, and then a finished piece is machined out. The use method of the multifunctional machining tool is simple in structure, economical, practical and high in machining precision.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a positioning device for performing milling and drilling multi-process processing on workpieces. Background technique [0002] Such as figure 1 The shown blank 1 contains a circular chassis 11 and a cylindrical boss 12 with a positioning hole, which needs to be processed as figure 2 Finished piece 2 shown, in figure 2 The finished product 2 shown is square, and the bottom surface 21 is a circular arc surface, and oblique holes 22 are distributed on the circular arc surface, and a counterbore 23 is included. In the traditional conventional processing method, the processed figure 2 As shown in the finished part 2, the peripheral surface of the chassis 11 of the blank 1 needs to be milled into a square on a milling machine, and the bottom surface of the chassis 11 is milled into the arc surface 21 of the finished part 2, and then the arc surface 21 is drilled. Inclined hole ...

Problems solved by technology

In the traditional conventional processing method, the processed figure 2 As shown in the finished part 2, the peripheral surface of the chassis 11 of the blank 1 needs to be milled into a square on a milling machine, and the bottom surface of the chassis 11 is milled into the arc surface 21 of the finished part 2, and then the arc surface 21 is drilled. Inclined hole 22; to complete the above process, if multiple sets of tooling fixtures are used, it will inevitably affect production efficiency and increase processing costs. However, if machining centers are used for processing, positioning tooling that can realize milling and drilling multi-process processing must be available.
