Detailed Implementation

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] Please see Figure 1-7 A heavy-duty three-head EDM machine includes a base module 1, a worktable 2 fixed on the base module 1, a column module 3 integrally formed on the side of the base module 1, three sets of X-axis slide plate modules 7 slidably arranged on the column module 3, a Y-axis crossbeam module 4 slidably arranged on the X-axis slide plate module 7, a Z-axis module 5 installed at the end of the Y-axis crossbeam module 4, and a head assembly 6 movably arranged on the side of the Z-axis module 5.

[0026] In practical use, by setting up the Y-axis crossbeam module 4, the X-axis slide module 7, and the Z-axis module 5, the entire head assembly can move along the X, Y, and Z axes. By setting up the first guide rail 303 and three sets of first ball screw structures on the column module 3, the second ball screw structure and the second guide rail 403 on the Y-axis crossbeam module 4, and the third ball screw structure and the third guide rail 503 on the Z-axis module 5, the head assembly 6 can move precisely along the X, Y, and Z axes with high accuracy. By setting up three sets of head assemblies 6, the three sets of head assemblies 6 can freely switch between collaborative and independent modes, significantly improving processing flexibility.

[0027] In this embodiment, the column module 3 is provided with three sets of first ball screw structures, which are respectively matched with three sets of X-axis slide modules 7. The first ball screw structure includes a first servo motor 301 and a first lead screw 302. The first servo motor 301 is installed in the column module 3, and the first lead screw 302 is installed at the output end of the first servo motor 301. The bottom of the X-axis slide module 7 is threadedly connected to the first lead screw 302. The column module 3 is provided with first guide rails 303 on both sides, and the X-axis slide module 7 is slidably mounted on the first guide rails 303. Specifically, the first servo motor 301 can be started to drive the first lead screw 302 to rotate, and the rotation of the first lead screw 302 can drive the X-axis slide module 7 to move. The setting of the first guide rails 303 can realize the precise movement of the X-axis slide module 7.

[0028] Among them, the three sets of first servo motors 301 can be connected to a microcontroller, and the three sets of first servo motors 301 can switch between collaborative / independent modes through microcontroller control.

[0029] In this embodiment, a second threaded block 703 is provided at the bottom of the X-axis slide module 7, and the second threaded block 703 is threadedly connected to the first lead screw 302. A first threaded block 701 is fixedly provided at the top of the X-axis slide module 7, and the first threaded block 701 is configured to cooperate with the Y-axis crossbeam module 4. Guide rails 702 are provided on both sides of the top of the X-axis slide module 7, and the guide rails 702 are configured to cooperate with the Y-axis crossbeam module 4. Specifically, the rotation of the first lead screw 302 can cause the second threaded block 703 to move. The movement of the second threaded block 703 can drive the X-axis slide module 7 to move along the X-axis direction, thereby driving the movement of the head assembly 6.

[0030] In this embodiment, a second ball screw structure is installed at the bottom of the Y-axis crossbeam module 4. The second ball screw structure includes a second servo motor 401 and a second lead screw 402. The servo motor 401 is installed at the bottom of the Y-axis crossbeam module 4, and the second lead screw 402 is installed at the output end of the servo motor 401. The second lead screw 402 is threadedly connected to the first threaded block 701. Second guide rails 403 are installed on both sides of the bottom of the Y-axis crossbeam module 4, and the second guide rails 403 are slidably connected to the guide rails 702. Specifically, the second lead screw 402 can be rotated by starting the second servo motor 401. The second lead screw 402 is threadedly connected to the first threaded block 701, and the first threaded block 701 is fixed to the top of the X-axis slide plate module 7. When the second lead screw 402 rotates, it will synchronously drive the second lead screw 402, the second servo motor 401, and the Y-axis crossbeam module 4 to move along the Y-axis direction. The setting of the second guide rails 403 and the guide rails 702 facilitates more precise movement.

[0031] In this embodiment, a third ball screw structure is installed on the Z-axis module 5. The third ball screw structure includes a third servo motor 501 and a third lead screw 502. The third servo motor 501 is installed on the top of the Z-axis module 5, and the third lead screw 502 is installed on the output end of the third servo motor 501. A threaded slider is provided on the side of the head assembly 6, and the threaded slider is threadedly connected to the third lead screw 502. A third guide rail 503 is installed on the side of the Z-axis module 5, and a guide groove matching the third guide rail 503 is provided on the side of the head assembly 6. Specifically, by starting the third servo motor 501, the third lead screw 502 is driven to rotate. The rotation of the third lead screw 502 can drive the head assembly 6 to move along the Z-axis direction. The setting of the third guide rail 503 and the guide groove can make the head assembly 6 move accurately along the Z-axis direction, which is highly practical.

[0032] In this embodiment, the bottom of the machine head assembly 6 is equipped with a machine head 601, which can be used to process products.

[0033] In this embodiment, the base module 1 is provided with a plurality of horizontal adjustment bolts 102 inside, and the ends of the horizontal adjustment bolts 102 are connected to support pads 101. Specifically, the support pads 101 can be moved by turning the horizontal adjustment bolts 102, thereby adjusting the tilt of the base module 1, which facilitates the horizontal placement of the entire EDM machine and provides auxiliary support for the entire EDM machine.

[0034] Operating principle: Operators adjust the leveling bolts 102 as needed to ensure the horizontal placement of the entire EDM machine and provide auxiliary support. By controlling three sets of first servo motors 301, three sets of Y-axis crossbeam modules 4 move along the X-axis. Independent or collaborative movement modes can be switched as needed. Starting the second servo motor 401 rotates the second lead screw 402. The second lead screw 402 is threadedly connected to the first threaded block 701, which is fixed to the top of the X-axis slide plate module 7. This ensures that when the second lead screw 402 rotates, it simultaneously moves the second lead screw 402, the second servo motor 401, and the Y-axis crossbeam modules 4 along the Y-axis. Starting the third servo motor 501 rotates the third lead screw 502, which in turn moves the head assembly 6 along the Z-axis, achieving precise movement of the head assembly 6 along the X, Y, and Z axes. After movement, the head assembly 6 and head 601 can be configured for machining operations.
