Problems solved by technology
[0002] In the current parts processing, there are many difficulties in processing the interference parts of complex parts. Especially when processing the roots of each interference part, there is no effective method. Generally, EDM or fitter repairing and file cleaning are used. However, EDM is limited by the size of the machine tool and the single processing direction. There is no good solution for some large parts and inside the cavity, and the cost is high.
Fitter repairing files, for some positions with large interference size, it is difficult to rely on manual repairing files to meet the size requirements of machining
[0003] For example, a part is an aluminum alloy structural part (dimensions 375×145×55), and there are two inner ribs in the part that need to be processed, because there is interference in all directions of the processing part, and the size requirements are relatively high (left and right sides The spacing tolerance is plus or minus 0.1), the conventional milling processing scheme cannot be implemented, and the fitter's manual grinding cannot guarantee the processing accuracy
If EDM is used, the efficiency and accuracy of EDM are difficult to meet the requirements due to the large processing area.

Embodiment 1
[0018] Such as figure 1 The shown tool mounting frame for complex part interference parts includes a plug-in section 11; one end of the plug-in section 11 is used for docking installation, and a cutting tool 21 is installed at the other end; the plug-in section 11 is close to the cutting tool 21 The location has at least two curved segments.
Embodiment 2
[0020] Based on Embodiment 1, the radial distance between the cutting tool 21 and the insertion section 11 is smaller than the length of a straight line on the insertion section 11 close to the butt installation end.
Embodiment 3
[0022] Based on Embodiment 1, the sum of the bending angles of the curved sections on the plug-in section 11 is greater than 90° and less than 270°.

The invention provides a cutter mounting rack for an interference part of a complex part. The cutter mounting rack comprises an insertion section; one end of the insertion section is used for butt joint installation, and the other end is provided with a cutting tool; and at least two bent sections are arranged on the inserting section close to the cutting tool. By means of the cutter mounting rack, machining interference parts can be effectively bypassed, the machining range of a machine tool is extended, cutting machining of the interference parts is achieved, compared with a spark ignition machining mode, the cost is lower, the machining efficiency is higher, and more reliable precision guarantee can be obtained compared with a bench worker filing mode.
