Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical discharge machining equipment technology, and in particular to a large-stroke structure electrical discharge small hole machine. Background Technology
[0002] With the rapid development of modern manufacturing, the demand for precision parts processing is increasing. Electrical discharge machining (EDM) technology plays a vital role in many fields, such as aerospace, automobile manufacturing, mold processing, and medical device industries. These industries often require the processing of high-precision, high-quality small holes to meet the performance and assembly requirements of complex parts.
[0003] Traditional EDM small hole milling machines have gradually revealed some limitations when faced with increasingly diverse and demanding processing tasks. For example, when processing workpieces of different thicknesses, their lifting and adjustment functions are often not flexible enough, making it difficult to quickly and accurately adapt to changes in workpiece thickness. Many traditional machines only have a single lifting structure, which limits the range of workpieces they can process. When encountering workpieces with large thickness differences, additional tooling or complex adjustment steps may be required, which not only increases processing preparation time but may also introduce human error, reducing processing accuracy and efficiency.
[0004] Furthermore, traditional EDM small hole machining centers also have shortcomings in terms of positioning accuracy. Some machines are prone to coordinate jitter when adjusting the lateral position and angle of the worktable or machining head. This is extremely detrimental to high-precision small hole machining. The jitter will cause the discharge gap between the electrode and the workpiece to be unstable, which will affect the machining quality, resulting in a large deviation in the diameter of the machined small hole, increased roughness of the hole wall, and even scrap. Moreover, traditional machines lack effective guidance and stabilization mechanisms when operating such as rocker arm deflection, which can easily lead to error accumulation during the machining process, further reducing the stability of machining accuracy.
[0005] In summary, in order to meet the needs of modern manufacturing for high-precision, high-efficiency, and highly adaptable EDM small hole machining, this utility model proposes an EDM small hole machining machine with a large stroke structure.

Furthermore, the design of using servo motors for motors one, two, and three provides precise control capabilities for the entire equipment, making the processing smoother and more efficient, thereby achieving higher processing accuracy and efficiency.

Since motors 24, 34, and 51 are all servo motors, high precision is maintained during adjustment. The rigid rail 42 also prevents coordinate jitter during and after adjustment, resulting in more accurate positioning.
