Embodiment Construction

[0032] Such as figure 1 The electrochemical machining method of the discrete suspension cathode shown. In this embodiment, the cathode suspension is required to be able to move in translation in the axial section of the workpiece, but not to move along the axial direction of the workpiece, and not to rotate in any direction. It is proposed to use as Figure 3-4 The structure shown fulfills this requirement.

[0033] Such as Figure 4 Shown, combined figure 1 It is explained that the cathode 8 is fixedly connected to the slide rail 4 in the y direction. The slide rail 4 in the y direction can move linearly along the y direction in the figure. The y-direction linear bearing 5 is mounted on the support plate 15. The x-direction linear bearing 13 is installed at the back of the support plate, so that the cathode moves linearly along the x-direction along with the support plate by the x-direction linear bearing 13; Picture 11 As shown, the x-direction linear bearing 13 is matched w...

Abstract

The invention discloses an electrochemical machining apparatus of a dispersed suspended cathode. The electrochemical machining apparatus of the dispersed suspended cathode comprises a cathode which is opposite to an anode workpiece and used for realizing electrochemical machining, wherein the cathode is arranged on a support unit in a floating connection manner and suspended upon an anode. The suspension manner is as follows: partial gravity of the cathode is supported by static pressure and dynamic pressure of electrolyte between the cathode and the anode, the other part of the gravity is supported by the support unit. Besides, a two-channel cathode machining lug boss is arranged at the lower part of the cathode in a dispersing manner. According to the suspended cathode provided by the invention, the transmission of the positioning error of the workpiece to the machining error of the workpiece is blocked by the suspended cathode provided by the invention, the distribution range of the electrochemical action on the surface of the workpiece is amplified by the discretization of the cathode, and meanwhile, a pulse current is supplemented to reduce machining gaps and enhance the duplication from the precision of the cathode to the precision of the workpiece, so that the machining precision is greatly improved.

Description

Technical field [0001] The invention relates to an electrochemical processing device, and more specifically, to the improvement of the support mode and structure of a cathode for electrochemical processing. Background technique [0002] Electrochemical machining is widely used in the surface machining of various metal parts because it is not limited by the hardness and toughness of the material, the obtained surface morphology is excellent, and the surface leveling efficiency is high. However, for a long time, electrochemical surface machining is mainly used for Improve the surface roughness of parts. With the development of social production, it is necessary for actual production to improve the macroscopic forming accuracy in the electrochemical surface finishing process. [0003] According to the material removal mechanism of electrochemical machining, the key to improving the accuracy of macro-forming is to increase the sensitivity of the removal amount to the gap between elect...
