Embodiment 1

[0029] This embodiment provides a transverse feed electrode, including: active rod 1 , top cover 3 , housing 6 , long connecting rod 7 , short connecting rod 8 , driven block 9 , replacement block 10 , and chassis 11 . The active rod 1 is inserted into the spring 2 and penetrates into the through hole in the middle of the top cover 3, and is connected with the long connecting rod 7 through the end slot. The range of motion of the active rod 1 is limited by its own structure in cooperation with the spring 2, the top cover 3, and the long connecting rod 7, so as to ensure that the dead point is not passed through during the motion. The unopened matching side of the long connecting rod 7 is connected with the driving rod 1, the opening matching side is inserted into the hole on the side of the driven block 9 and connected with the driven block 9, and the opening matching side of the short connecting rod 8 is inserted into the winding in the middle of the long connecting rod 7.

Embodiment 2

[0031] This embodiment provides a method of using the transverse feed electrode to process the annular groove on the inner wall of the tubular workpiece:

[0032] 1. Design the chip replacement block 10, the specific structure is as follows Figure 6 As shown, press the electrode so that the raised part of the driven block 9 is exposed, and install the replacement block 10;

[0033] 2. Install a centering and axial fixing mechanism on the inner wall of the tubular workpiece, adjust the axial position so that the position of the replacement block 10 is aligned with the processing position after the tip is matched with the electrode, and then clamp the tubular workpiece on the workbench;

[0034] 3. Clamp the electrode on the spindle of the machine tool, select three points on the outer wall of the tubular workpiece (if the diameter of the inner wall is suitable, select the inner wall) for axis center positioning (X, Y direction), and the axial positioning of the electrode (Z dir...

Abstract

The invention discloses a transverse feed electrode. The transverse feed electrode comprises an outer shell, a top cover, a chassis, a driving rod, a connecting rod and a replacement block. The driving rod is used for being connected with a main shaft of a machine tool and transmitting the motion of the main shaft of the machine tool; the connecting rod is used for converting the vertical motion of the main shaft of the machine tool into horizontal motion; the outer shell is used for supporting the electrode to move, and the positioning of the electrode is facilitated; and the replacement block is used for discharging machining, and can be replaced after a certain loss occurs. The electrode realizes the conversion of the vertical motion and the horizontal motion, improves the machining precision of a hole, an annular groove and other complex structures on the vertical wall, and enlarges the application range of the electric spark machine tool.

Description

technical field [0001] The invention belongs to the technical field of special processing, in particular to a feed electrode for transverse processing. Background technique [0002] With the development of precision machining technology, some mechanical parts, such as air bearings, moulds, water nozzles, optical measuring equipment, etc., in addition to the requirements for precision, also require some special shapes to be made on high-hardness materials. However, these mechanical parts have certain limitations in the manufacturing process, especially the holes or annular grooves on the vertical walls, and the existing conditions are difficult to meet the processing requirements of these structures. Currently used methods are electrochemical machining only. Although the electrochemical processing method is convenient, it is easy to cause environmental pollution during the processing. Electrical discharge machining (EDM) is an alternative in the field of precision machining...
