Turning tool capable of achieving rapid clamping and rapid clamping method using same

Abstract

The invention relates to the technical field of machining of thin-walled parts, in particular to a turning tool capable of achieving rapid clamping. The turning tool comprises a base, a lower positioning device and an upper positioning device, wherein the lower positioning device and the upper positioning device are sequentially installed on the base from bottom to top, the turning tool further comprises a driving device, each of the upper positioning device and the lower positioning device is composed of a plurality of supporting blocks, moreover, the plurality of supporting blocks of each ofthe upper positioning device and the lower positioning device are arranged at intervals to form a circular support for the part correspondingly, a fitting surface matched with the inner wall of the part is arranged on the outer wall of each supporting block, the driving device can drive the supporting blocks in the upper positioning device to move synchronously, and can drive the supporting blocks in the lower positioning device to move synchronously. The turning tool achieves positioning through an upper section and a lower section, the circular supports are formed to the part from the innerwall of the part, then the problem that the quality of the part is influenced in the machining process due to insufficient strength of the thin-wall part is solved, the thin-walled part can be quickly clamped, the inner parts are tightly attached, then the cutting parameters can be improved, the production efficiency can be improved, batch machining can be realized, and the mass production chokepoint can be broken through.

Description

technical field [0001] The invention relates to the technical field of machining of thin-walled parts, in particular to a fast clamping turning tool and a fast clamping method thereof. Background technique [0002] In the turning processing of thin-walled parts such as engines, spacecraft shells, and missile barrels, conventional processing methods generally require multiple clamping and repeated positioning, and there are problems such as displacement and deformation during processing. Unstable clamping is prone to the problem of knife chatter. [0003] like Figure 9 As shown, it is an aircraft engine combustion chamber casing part 7. It is necessary to process the upper section 701 and the lower section 702 of the part 7, and trim the upper and lower sections of the part to facilitate the later welding process. However, the upper and lower sections of the part both extend to the inside of the part. , showing two undercut shapes, the undercut angle is relatively large, an...

Problems solved by technology

[0004] The purpose of the invention is to solve the technical problems in the prior art that when the thin-walled parts with undercuts at the upper and lower ends are turned, the parts are deformed and displaced due to unstable clamping, resulting in unqualified parts, and to provide A quick clamping turning tool, the turning tool forms a circular support for the part from the inner wall of the part through the upper and lower positioning of the turning tool, which solves the problem that the insufficient strength of the thin-walled part affects the quality of the part during processing, and realizes Quick clamping and tight fit inside are conducive to improving cutting parameters, improving production efficiency, realizing batch processing, and breaking through the bottleneck of mass production
