[0001] This utility model relates to the field of wire EDM machine tool clamping technology, specifically a clamping device for a CNC wire EDM machine tool. Background Technology

[0002] Wire EDM machines fall under the category of electrical discharge machining. The basic physical principle is that free positive ions and electrons accumulate in an field, quickly forming an ionized conductive channel. CNC wire EDM, like EDM forming, directly uses electrical and thermal energy to process the workpiece. It can process various conductive materials that are difficult to process by general cutting methods, such as high-hardness, high-brittleness, high-toughness, and high-thermal-sensitivity metals or semiconductor materials.

[0003] In the machining process of CNC wire EDM machines, precise workpiece clamping is a crucial step. Traditional clamping devices often suffer from unstable clamping and inaccurate positioning. Some devices, due to the unadjustable clamping force, may damage the workpiece or fail to clamp it securely. At the same time, some devices are cumbersome and inefficient in positioning the workpiece, failing to meet the demands of fast and precise production. Therefore, it is necessary to design a new clamping device for CNC wire EDM machines. Utility Model Content

[0030] Example 1:

[0031] A preferred embodiment of the clamping device for a CNC wire cutting machine provided by this utility model is, for example... Figure 1-4The image shows a clamping device for a CNC wire cutting machine tool, comprising a support leg 1, a CNC wire cutting machine tool body 2 fixedly mounted on the top of the support leg 1, a worktable 3 fixedly mounted on the top of the CNC wire cutting machine tool body 2, a control box 4 fixedly mounted on the top of the worktable 3, a cutting mechanism 5 fixedly mounted on the top of the worktable 3, a protective railing shell 31 fixedly mounted on the top of the worktable 3, a protective door 32 hinged to the front of the protective railing shell 31, and a handle 33 fixedly mounted on the front of the protective door 32; a centering clamping assembly 6, positioned above the worktable 3; the centering clamping assembly 6 includes: a centering alignment part 61 positioned above the worktable 3; and a limiting clamping part 62 positioned above the worktable 3, and the limiting clamping part 62 is located above the centering alignment part 61.

[0032] The center alignment part 61 includes: a mounting platform 611, which is fixedly installed on the top of the workbench 3; the top of the mounting platform 611 is provided with a mounting groove 612, and the top of the mounting platform 611 is provided with a sliding hole 613, which is located above the mounting groove 612; the bottom of the inner wall of the mounting groove 612 is fixedly installed with a sliding strip 614, which is two in a group, and there are two groups in total.

[0033] The top of the slide bar 614 is slidably connected to the slide seat 615. The top of the slide seat 615 is fixedly installed with the mounting plate 616, and there are two sets of them. The bottom of the inner wall of the mounting groove 612 is fixedly installed with the rotating column 617. The outer wall of the rotating column 617 is provided with the rotating plate 618 through the mounting ring.

[0034] The mounting groove 612, sliding hole 613, and slide bar 614 provide a track for the sliding seat 615 to slide. The sliding seat 615 can slide freely on the slide bar 614, thereby driving the mounting plate 616 above it to move.

[0035] A connecting block 619 is fixedly installed on the top of the mounting plate 616, and the connecting block 619 is centered. A connecting block 6110 is fixedly installed on the top of the rotating plate 618, and there are two sets of them, located at both ends respectively. A connecting rod 6111 is fixedly installed between the connecting block 619 and the connecting block 6110, and there are two sets of them.

[0036] By setting up a rotating column 617 and a rotating plate 618, and cooperating with the connection of connecting block 1 619, connecting block 2 6110 and connecting rod 6111, the rotational adjustment of the mounting plate 616 and the placement of the centering plate 6113 is realized, so that the workpiece can be finely adjusted on the horizontal plane to achieve the purpose of centering and alignment.

[0040] Example 2:

[0041] Based on Embodiment 1, a preferred embodiment of the clamping device for a CNC wire cutting machine tool provided by this utility model is, for example... Figure 1-4 As shown: The limiting clamping part 62 includes: a slide groove 621, which is opened on the top of the centering plate 6113, and there are two of them as a group, for a total of two groups; a second cylinder 624, which is fixedly installed on the outer wall of the centering plate 6113 via a support plate; a guide rod 622 is fixedly installed inside the slide groove 621, and an installation block is slidably connected inside the slide groove 621, and the installation block is movably sleeved on the outer wall of the guide rod 622; a sliding plate 623 is fixedly installed on the top of the installation block, and the connecting end of the second cylinder 624 is fixedly installed on the outer wall of the sliding plate 623 via a connecting rod.

[0042] The slide 621 and guide rod 622 provide a track and support for the sliding of the slide plate 623. The slide plate 623 can slide freely within the slide 621, while being restricted by the guide rod 622 to ensure the stability and accuracy of the sliding.

[0043] Limiting posts 625 are fixedly installed at equal intervals on the top of the slide plate 623, an L-shaped support plate 626 is fixedly installed on the top of the slide plate 623, and springs 627 are fixedly installed at equal intervals on the top of the slide plate 623.

[0044] The movement of the slide plate 623 is powered by a second cylinder 624. The extension and retraction of the second cylinder 624 can push the slide plate 623 to move along the slide groove 621, thereby achieving the clamping of the workpiece.

[0045] The limiting post 625 provides support and guidance for the clamping plate 629. The clamping plate 629 is movably sleeved on the outer wall of the limiting post 625 to ensure that it does not deviate from the track during clamping.

[0046] The L-shaped support plate 626 has a connection hole at the top, and an adjusting rod 628 is provided inside the connection hole. A pressure plate 629 is fixedly installed at the bottom of the adjusting rod 628, and the pressure plate 629 is movably sleeved on the outer wall of the limiting post 625. The bottom of the pressure plate 629 is fixedly installed on the top of the spring 627.

[0047] The clamping force of the pressure plate 629 on the workpiece is changed by adjusting the height of the adjusting rod 628, which is equipped with an L-shaped support plate 626, a spring 627, and an adjusting rod 628. Meanwhile, the spring 627 provides a buffering effect during clamping, preventing damage to the workpiece.

[0048] Furthermore, in this embodiment, a second cylinder 624 is provided to drive the slide plate 623 to slide rapidly along the slide groove 621 and the guide rod 622, so that the limiting post 625 is limited. At the same time, the clamping plate 629 is connected to the slide plate 623 through the spring 627 to prevent the workpiece from being damaged due to excessive force during the clamping process. With the help of the adjusting rod 628, the clamping force of the clamping plate 629 on the workpiece is adjusted, so that the clamping device can adapt to workpieces of different sizes and materials.

[0049] In operation, the workpiece is first placed on the centering plate 6113. Then, driven by cylinder 6112, the sliding seat 615 and the mounting plate 616 move along the slide bar 614 to adjust the horizontal position of the workpiece and achieve center alignment. Furthermore, by adjusting the rotating column 617 and the rotating plate 618, the angle of the workpiece can be further fine-tuned to ensure that the workpiece is completely aligned with the cutting path. After the workpiece position is determined, cylinder 624 starts working, pushing the sliding plate 623 to move along the slide groove 621 and the guide rod 622, so that the clamping plate 629 is close to the workpiece. By adjusting the height of the adjusting rod 628, the clamping force of the clamping plate 629 on the workpiece can be adjusted. Under the action of the spring 627, the clamping plate 629 can flexibly clamp the workpiece, which is both stable and safe. Finally, the cutting mechanism 5 is started, and the workpiece is precisely cut under the control of the CNC wire cutting machine body 2. Throughout the process, the protective railing shell 31 and the protective door 32 provide safety protection for the operator and prevent injury from flying debris generated during the cutting process.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
