Abstract

The invention discloses a guide plate type part wire-electrode cutting fixture and method. Firstly, a first fixture assembly A (1) is installed on a wire-electrode cutting machine tool and fixed; next, the inner surface of a part (6) to be machined is attached to a first positioning face and a second positioning face of the first fixture assembly A (1) and a front end face of a second fixture assembly B (2); then, a positioning dowel (5) is inserted into the part, a second positioning hole of the second fixture assembly B (2) and a first positioning hole of the first fixture assembly A (1); and two pressing plates (3) are pressed to the part (6), clamping to the part (6) is achieved, meanwhile, a plurality of auxiliary supporting points (7) are added to the lower end position of the part (6), and wire-electrode cutting machining of the part (6) is carried out. According to the guide plate type part wire-electrode cutting fixture and method, the structure is simple, operation is convenient, and rapidness, high efficiency, stability and reliability are achieved.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a device and a cutting method for realizing rapid positioning and clamping during wire cutting of guide plate parts. Background technique [0002] Among engine components, there are a large number of guide plate parts. Such as image 3 and Figure 3-1 As shown, in order to improve efficiency, the part is usually processed into a ring in production, and then cut into multiple parts by wire cutting. Due to the structural characteristics of the guide plate parts, the cutting edge of the guide plate forms an angle θ with the central axis of the ring. Therefore, during wire cutting operations, the end face of the ring cannot be used for positioning and clamping. It is difficult to use conventional fixtures for clamping and positioning, resulting in low processing efficiency and unstable quality of parts. Especially in mass production, it seriously affects the proces...
