Problems solved by technology

[0004] The object of the present invention is a milling tool for tapered thin-walled parts. The present invention fully analyzes the part profile structure, and combines the difficulty of fixture manufacturing process to design the support structure of the thin-walled tapered part fixture as a fixed inner surface auxiliary support. , eliminating the problem of out-of-tolerance roundness of the auxiliary support surface of the radially adjustable auxiliary support type fixture, and adopting the adjustment of axial parts in the clamping instead of the traditional radial fixture adjustment, which fundamentally solves the out-of-tolerance of the roundness of the parts after clamping And the problem of uneven wall thickness and excessive wall thickness of the parts after processing caused by the gap between the fixture and the parts

Embodiment Construction

[0020] combined with figure 1 The notations describe the invention in detail.

[0021] (1) Remove gland 1: put figure 1 The upper hold down bolt 2 is shown with the gland removed.

[0022] (2) Adjust the bottom support: set figure 1 The shown bottom adjustable bolt 3 is rotated counterclockwise for adjustment, driving the bottom support ring 6 to move down until the bottom support ring contacts the base of the fixture 5 and stops.

[0023] (3) Align the base: place the fixture on the center of the machine table, and align in the circumferential direction figure 1 The shown fixture aligning belt 4 compresses the fixture base and the workbench surface.

[0024] (4) Clamping parts: press the parts figure 1 The orientation shown is set on the matching tapered surface of the fixture body.

[0025] (5) Circumferential adjustment: adjust the circumferential position of the part to align with the machining angle.

[0026] (6) Assembly gland: put figure 1 The gland shown is pla...

Abstract

The invention relates to a milling tool for a conical thin-walled part, and a brand-new structural tool for milling the thin-walled conical part is designed and manufactured by analyzing part characteristics. A tool support mechanism, a tool adjustable mechanism, a tool axial datum and a tool pressing mechanism are included. The deformation control effect on the conical thin-walled part is remarkable, all mechanisms of the tool are simple in cooperation, and reliability is high. Tool operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular designs a milling tool for tapered thin-walled parts, which belongs to a general fixture and is suitable for milling and clamping of tapered thin-walled parts. Background technique [0002] There are many kinds of materials for casing parts in aero-engines, among which thin-walled parts with tapered inner surfaces occupy a certain proportion. The wall thickness of such parts is generally between 0.8-2.5mm. Due to the material removal rate of such thin-walled parts Both reach about 90%. The parts are easily deformed during processing. After the parts are processed, there are likely to be uneven wall thicknesses or excessive wall thicknesses. Generally, the milling fixture structure of this type of parts is designed as an internal radially adjustable auxiliary support structure, but , the reliability of this type of adjustable auxiliary support is low, and there are ...
