Description

Technical Field

[0001] The utility model relates to the technical field of spark machines, in particular to a single-side multi-head spark machine. Background Art

[0002] Electrical Discharge Machining (EDM), short for electrical discharge machining, is a type of machining equipment primarily used for electrical discharge machining (EDM). It is widely used in the manufacture of various metal molds and mechanical equipment. EDM is a specialized machining method that uses the electro-erosion effect generated by a pulsed discharge between two electrodes immersed in a working fluid to remove conductive materials. It is also known as electrical discharge machining (EDM) or electro-erosion machining.

[0003] For drilling holes in parallel on some identical workpieces, a multi-head EDM machine can be used to improve processing efficiency. Patent No. CN215545566U discloses a multi-head high-efficiency EDM machine, which uses a multi-head EDM machine to work simultaneously to improve efficiency. Although the scheme can change the spacing between different spark units, it cannot make different spark units staggered front and back. Therefore, it can only process nodes on a straight line, which is not very practical. Based on this, this scheme designs a multi-head EDM machine that can move flexibly and process on more than one straight line. Utility Model Content

[0037] As Figures 1-5 A single-sided multi-head spark machine includes a base 100 and a workbench 300. The base 100 is provided with at least two groups of slidingly connected spark units 200, and the spark unit 200 is an independent unit for electric spark machining. The side of the base 100 is provided with the workbench 300.

[0038] The spark unit 200 comprises an X-axis sliding member 210, a Y-axis sliding member 220, a Z-axis sliding member 230, and a spark head 240. The X-axis sliding member 210 is slidingly connected to the top of the base 100, the Y-axis sliding member 220 is slidingly connected to the top of the X-axis sliding member 210, the Z-axis sliding member 230 is slidingly connected to the end of the Y-axis sliding member 220 and is located above the workbench 300. The spark head 240 is arranged at the bottom of the Z-axis sliding member 230.

[0039] The X-axis sliding member 210, the Y-axis sliding member 220, and the Z-axis sliding member 230 determine the control and displacement of the three directions of the spark head 240, thereby enabling the spark head 240 to freely move on the workbench 300. As a plurality of spark units 200 arranged on one side of the workbench 300, the plurality of spark units 200 can simultaneously perform synchronous electric spark machining on non-standard points of a workpiece on the workbench 300, and have strong practicability.

[0040] Specifically, the X-axis sliding member 210 comprises a first sliding rail 211, a first sliding table 212, a first driving motor 213, a first ball screw 214, and a first shaft head 215. The first sliding rail 211 is arranged on the top of the base 100. Since there is a certain load requirement above, the first sliding rail 211 of the present solution is provided with two symmetrical groups, and is respectively located at the two ends of the top of the base 100. The double-track design on both sides improves the precision and smoothness of sliding. The first sliding table 212 is slidingly connected to the first sliding rail 211. The first driving motor 213 and the first ball screw 214 are arranged on the top of the base 100. The first shaft head 215 is sleeved on the first ball screw 214 and is fixedly connected with the first sliding table 212. The fixed mode is bolted or clamped. The first driving motor 213 drives the first ball screw 214 to rotate, thereby driving the first shaft head 215 to slide. The first shaft head 215 slidingly drives the first sliding table 212 to slide on the first sliding rail 211.

[0041] Since a plurality of groups of X-axis sliding members 210 are arranged in parallel on the base, in order to avoid mutual interference, a limiting plate 216 is arranged on both sides of the first sliding table 212. The bearings at both ends of the first ball screw 214 form a limit to the limiting plate 216. At the same time, the limiting plates 216 of adjacent X-axis sliding members 210 can also limit each other to avoid interference. In order to utilize the effect of avoiding interference by abutting against each other, the limiting plates 216 of each group of spark units 200 are located on the same straight line.

[0042] Specifically, the Y-axis slider 220 includes a second slide rail 221, a second slide table 222, a second drive motor 223, a second ball screw 224 and a second shaft head 225. The second slide rail 221 is arranged on the top of the first slide table 212. Since there is a certain load requirement above, the second slide rail 221 of the present solution is provided with two symmetrical groups, and is respectively located at the top of the two ends of the first slide table 212. The second slide table 222 is slidingly connected to the second slide rail 221. The second drive motor 223 and the second ball screw 224 are arranged on the top of the first slide table 212. The second shaft head 225 is sleeved on the second ball screw 224 and is fixedly connected with the second slide table 222. The second drive motor 223 drives the second ball screw to rotate, thereby driving the second shaft head 225 to slide. The second shaft head 225 slidingly synchronously drives the second slide table 222 to slide on the second slide rail 221.

[0043] Specifically, the Z-axis slider 230 includes a third slide rail 231, a third slide table, a third drive motor 233, a third ball screw 234 and a third shaft head 235. The third slide table is slidingly connected to the third slide rail 231. Since there is a certain load requirement, and the third slide table has a certain volume, the third slide rail 231 of the present solution is provided with two symmetrical groups. The third shaft head 235 is sleeved on the third ball screw 234 and is fixedly connected with the third slide table. The third drive motor 233 drives the third ball screw 234 to rotate, thereby driving the third shaft head 235 to slide. The third shaft head 235 slidingly synchronously drives the third slide table to slide on the third slide rail 231.

[0044] The plurality of spark units 200 control the respective spark heads 240 to reach the specified working point by using the respective independent X-axis slider 210, Y-axis slider 220 and Z-axis slider 230. The spark unit 200 can freely move on the X, Y and Z axes, and can effectively process some non-standardized products.

[0045] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
