Machining method for sheet parts

Abstract

The invention discloses a machining method for sheet parts and belongs to the technical field of machining. The machining method of a thin plate type part comprises steps that a blank is placed on a workbench of a numerical control lathe, an outer circle of a part is machined on the blank, a center through hole and a first blind hole of the part are machined with the outer circle of the part as abenchmark, cutting off the blank is performed to obtain a semi-finished part, a first tool is placed on the workbench of the numerical control lathe, a groove is machined on an end face of the first tool, a second tool is placed in the groove, the semi-finished part is placed in the groove, the second tool is embedded into the first blind hole to support the semi-finished part, the semi-finished part is pressed in the groove, thickness of the part is machined, a second blind hole of the part is machined, and a finished part is obtained. The machining method can prevent the part from shaking inthe machining process, the form and location tolerance of the part is guaranteed, and high-precision machining of the part is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing method for thin plate parts. Background technique [0002] The thickness of high-precision thin-plate parts with suspended ribs is required to be 5mm, and the parallelism is required to be 0.1mm; and there is a suspended circular rib structure in the middle, the thickness of the ribs is 2mm, and the thickness tolerance is required to be 0.1mm. The mechanical processing of this type of parts mainly has the following technical difficulties: (1) the thickness of the parts is thin, it is difficult to clamp and ensure the dimensional tolerance; (2) the middle rib is a suspended structure, and the shape and position tolerance is difficult to guarantee. [0003] At present, the processing of high-precision thin-plate parts with suspended ribs is to clamp the outer circle of the part with soft jaws to process blind holes. However, after the part is cut directl...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a processing method for thin plate parts, which solves or partially solves the problem that the high-precision thin plate parts of the suspended ribs in the prior art are too thin, it is difficult to flatten the end surface, and it is difficult to ensure the flatness of the end surface, and the middle rib is processed. It is easy to tremble when the rib plate is installed, which causes the technical problem that the shape and position tolerance accuracy of the rib plate is unqualified
