Problems solved by technology

The processing method adopted for the structure of the groove is to use the electrode for electric discharge machining, but it is difficult to find the center of the ball socket when using this method. If there is a deviation between the processed groove and the center of the ball socket, the ball cannot be loaded. The conventional electrode structure cannot guarantee that the machined groove is concentric with the ball socket, and there are cases where the ball cannot be installed

Embodiment Construction

[0026] The use of this electrode will be described in detail below in conjunction with the drawings:

[0027] Such as figure 1 , Figure 5 with Image 6 Shown is the DXX17F engine adjusting plate, which respectively indicate the ball socket and the groove to be machined on the part. After milling the Φ13 ball socket on the machining center, the part needs to machine 13.5*8.5*3 groove, but CNC milling cannot Obtained, which is linked to the method of electrical pulse processing.

[0028] figure 2 with image 3 It is a schematic diagram of the electrode structure with the aligning function, including the electrode clamping section 1 at the end of the electrode and connected to the EDM machine tool, and the stepped electrode working section 2 for ball and socket processing. The front end of the electrode working section 2 is used for Align the ball head 3 in the center of the ball socket; the electrode working section 2 is an axisymmetric structure, including a pair of arc surfaces ...

Abstract

The invention discloses an electrode ball socket groove machining method with a self-aligning function. An electrode includes an electrode clamping section at the tail end of the electrode and connected with an electric spark machine tool, and an electrode working section for ball socket machining. The front end of the electrode working section is provided with a ball head used for aligning the center of a ball socket; the electrode working section is of an axial-symmetry structure including a pair of arc-shaped surfaces symmetrical about the axis of symmetry; and the center of the ball head is located in the extension line of the axis of symmetry of the arc-shaped surfaces of the electrode working section. By modifying a conventional electrode, an electric spark machining device has a correcting function and ensures that a groove machining by the electrode is concentric with a sphere, so that the assembly requirements can be met.

Description

Technical field [0001] The invention relates to a method for quickly determining the relative position of a part and an electrode in an aeroengine part in EDM, and an electrode structure. The electrode structure can overcome the disadvantage that the position of the part cannot be quickly corrected in conventional machining. Background technique [0002] In the aviation industry, many structures involve the connection of the ball head. The parts involved include the ball socket of the main body and the ball installed in it. To enter the main ball socket, a groove needs to be machined on the end of the ball socket to ensure the ball's performance. Load into the ball socket. The processing method used for the structure of the groove is to use the electrode for EDM, but it is a problem to find the center of the ball socket when using this method. If the processed groove and the center of the ball socket are deviated, the ball cannot be loaded. The conventional electrode structure c...
