Embodiment Construction

[0046] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0047] Such as Figure 1-3 As shown, it can be obtained from formula 1) that:

[0048] {[(ΦD1-ΦD2) / 2]-α} / L= {[(186-134) / 2]-5} / 285≈1:14

[0049] It exceeds the boring capacity of the vibration-damping tool bar, so it needs to be processed by the processing tool and the processing method of the present invention. When processing, specify a CNC lathe with better rigidity and precision; select a standard alloy turning blade for processing ultra-high-streng...

Abstract

The invention discloses a machining tool and machining method for a deep and long annular cavity. The machining tool comprises a tool body and a blade fixed to the tool body; the tool body comprises a working part used for supporting the blade to work and a clamping reinforcing part which is convenient for clamping and is used for reinforcing the strength of the tool body; the working part and the clamping reinforcing part of the tool body are each provided with a tool body front side face achieving profile modeling with the inner side face of the deep and long annular cavity, and the working part of the tool body is provided with a tool body rear side face achieving profile modeling with the outer side face of the deep and long annular cavity; the thickness of the working part of the tool body is smaller than the distance between the outer side face and the inner side face of the deep and long annular cavity. According to the machining tool and machining method for the deep and long annular cavity, operation is easy, the machining efficiency is high, the product quality is easily guaranteed, and the problem that a deep and long annular cavity type structure is difficult to machine can be effectively solved.

Description

technical field [0001] The invention relates to a processing tool and a processing method for a deep and long annular cavity, belonging to the technical field of mechanical processing technology. Background technique [0002] The deep and long annular cavity refers to the annular cavity with an aspect ratio greater than 10. It is mainly used for workpieces whose depth exceeds the processing range of the international standard vibration-damping tool holder (length: diameter ≥ 10:1, except for the clamping length). [0003] Such as figure 1 Shown is a typical workpiece structure processed with a deep and long annular cavity. Due to the narrow space and the interference of ordinary tools, this type of structure cannot be penetrated deeply, and the processing is very difficult. Generally, such workpieces are designed to be welded or assembled, but with the application of ultra-high-strength steel and the requirement that the landing gear and the aircraft body have the same life...
