[0022] Reference Figure 1 As shown, an embodiment of the present invention provides an electrode fixing device for an EDM machine, comprising a connecting assembly 100 and a standard connecting plate 200.
[0023] The connecting assembly 100 is used to connect to the EDM machine; the standard connecting plate 200 is fixed to the connecting assembly 100, and the standard connecting plate 200 is provided with multiple sets of positioning connecting holes 201. The standard connecting plate 200 is used to connect and fix electrodes.
[0024] Once the connecting assembly 100 is connected to the EDM machine, it is generally not disassembled. When it is necessary to replace the electrode, the connection structure between the standard connecting plate 200 and the electrode is used for disassembly. The standard connecting plate 200 is provided with multiple sets of positioning connection holes 201. The electrode and the standard connecting plate 200 are connected through the corresponding positioning connection holes 201, which provides high positioning accuracy and eliminates the need for complex positioning adjustments.
[0025] It is understood that the connecting assembly 100 includes a column 110, one end of which is provided with a connecting flange 120, and the other end of the column 110 is fixedly connected to a standard connecting plate 200.
[0026] The column 110 serves to support the transmission mechanism. A connecting flange 120 is provided at the end of the column 110, increasing the contact area of the connection. The connecting flange 120 and the column 110 can be fixedly connected by welding or by a one-piece structure machined by turning and milling. In some embodiments, the column 110 can be a column with an outer diameter of 100mm and a height of 120mm. The standard connecting plate 200 can be a 500mm×400mm×15mm square precision-ground standard steel plate. The positioning connecting holes 201 on the standard connecting plate 200 can be configured as multiple countersunk bolt holes of various sizes (8mm / 10mm / 12mm), and the specific arrangement can be designed according to actual needs. In the above embodiments, after electrode replacement, actual measurements show that the repeatability accuracy can reach the ±0.05mm level.
[0027] The standard connecting plate 200 is suitable for connecting electrodes of various shapes and sizes. For example, cylindrical, square, and irregularly shaped electrodes can all be connected to the standard connecting plate 200. It only requires that the mounting surface of the electrode is provided with a positioning connector that matches the positioning connection hole 201 of the standard connecting plate 200, which reduces the investment cost of special fixtures for different types of electrodes.
[0028] Reference Figure 2 As shown, it can be understood that the connecting flange 120 is provided with a plurality of first connecting bolts 130, which are evenly spaced around the circumference of the connecting flange 120.
[0029] The first connecting bolt 130 is connected to the corresponding connecting part of the EDM machine to fix the connecting flange 120 to the EDM machine. Preferably, the number of the first connecting bolts 130 is set to four, and the four first connecting bolts 130 are evenly distributed around the circumference of the connecting flange 120, with the included angle between two adjacent first connecting bolts 130 being 90°.
[0030] It is understandable that the center of the column 110 has a through hole, which is parallel to the central axis of the column 110.
[0031] The column 110 has a through hole formed at its center by removing material, which reduces the mass of the column 110 while still maintaining sufficient structural strength.
[0032] Reference Figure 3 As shown, it can be further understood that the through hole of the column 110 is threaded, and the thread extends from one end of the column 110 away from the connecting flange 120 toward the other end of the column 110. The standard connecting plate 200 is provided with a second connecting bolt 140, which is connected to the thread of the through hole of the column 110.
[0033] Threads can be machined into the through hole of the column 110, and the standard connecting plate 200 can be connected to the column 110 in conjunction with the second connecting bolt 140. In some embodiments, the column 110 is a hollow cylinder with an outer diameter of 100 mm, a thickness of 80 mm, and a height of 120 mm.
[0034] It is understood that the standard connecting plate 200 is provided with an extension component 300, which is connected to the standard connecting plate 200. The length direction of the extension component 300 is perpendicular to the plate surface of the standard connecting plate 200. The extension component 300 is located on the side of the standard connecting plate 200 away from the connecting component 100. The end of the extension component 300 away from the standard connecting plate 200 is used to connect an electrode.
[0035] An extension component 300 is provided between the standard connecting plate 200 and the electrode, which can increase the distance between the electrode and the EDM machine, that is, reduce the distance between the electrode and the workpiece being processed, and reduce the movement distance of the electrode during the processing.
[0036] Reference Figure 4 As shown, it can be understood that the extension assembly 300 includes a plurality of connecting posts 310, the axis of the connecting posts 310 being perpendicular to the surface of the standard connecting plate 200, one end of each connecting post 310 being fixedly connected to the standard connecting plate 200, and the other end of the connecting post 310 being used to connect an electrode.
[0037] Multiple connecting posts 310 are used to connect the electrode to the standard connecting plate 200, providing multi-point support for the electrode and increasing its stability. Furthermore, this multi-point support also maintains the positioning accuracy of the electrode installation. It's important to understand that even when the connecting posts 310 connect to the positioning connection holes 201 of the standard connecting plate 200, precise positioning for the electrode installation is still possible. It's also important to understand that the multiple connecting posts 310 can be adjusted in position relative to the standard connecting plate 200 according to the electrode size. The standard connecting plate 200 has multiple sets of positioning connection holes 201, allowing the connecting posts 310 to select appropriate holes for connection.
[0038] It is understandable that the end of the connecting column 310 is provided with a first flange 311, which is fitted and connected to the standard connecting plate 200.
[0039] The first flange portion 311 contacts the surface of the standard connecting plate 200. Furthermore, it is understood that the first flange portion 311 is provided with a plurality of third connecting bolts 320, which engage with the positioning connecting holes 201. Preferably, the number of third connecting bolts 320 can be set to four, with the four third connecting bolts 320 evenly spaced around the circumference of the first flange portion 311.
[0040] It is understandable that the end of the connecting column 310 is also provided with a second flange 312, which is located on the opposite side of the first flange 311 and is used to connect the electrode.
[0041] The second flange portion 312 is used to contact the mounting surface of the electrode. It should be understood that the mounting surface of the electrode is also provided with multiple connection holes, and a fourth connecting bolt can also be provided on the second flange portion 312 to fix the second flange portion 312 to the electrode. Preferably, four fourth connecting bolts are provided on the second flange portion 312, and the fourth connecting bolts are evenly spaced around the circumference of the second flange portion 312.
[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
