[0047] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0048] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0049] This disclosure provides a clamping fixture for multi-wire cutting, which is applied to multi-wire cutting equipment. The clamping fixture provided by this disclosure can effectively improve the problems of complex assembly process and poor clamping accuracy of multi-wire cutting equipment during use.

[0050] Please refer to Figures 1 to 7. The clamping fixture for multi-wire EDM provided in this disclosure includes a base 100, a clamping mechanism 200, and a positioning mechanism 300. The clamping mechanism 200 is connected to the base 100 and is used to clamp the workpiece. During the clamping process, the workpiece can be positioned by the positioning mechanism 300, thereby improving the accuracy of the workpiece in the clamping mechanism 200. The clamping fixture of this disclosure can effectively simplify the assembly process, shorten the production preparation time, and improve the overall production efficiency.

[0051] A first connecting base surface 101 for placing the workpiece to be cut is provided on the base 100, and a clamping mechanism 200 is disposed above the base 100. The clamping mechanism 200 is used to clamp the workpiece and fix the workpiece relative to the base 100.

[0052] It should be noted that multiple clamping mechanisms 200 are provided, and these multiple clamping mechanisms 200 are distributed at intervals on the base 100. Therefore, by using multiple clamping mechanisms 200 distributed at intervals on the base 100, multiple workpieces to be cut can be evenly connected on the base 100.

[0053] Specifically, through the coordinated operation of the clamping mechanism 200 and the positioning mechanism 300, the workpiece is accurately positioned and clamped, providing a stable and reliable precision guarantee for cutting processing.

[0054] Referring to Figures 1 to 7, in one embodiment, a first connecting panel 110 and a second connecting panel 120 are connected to the base 100. A clamping area is included between the first connecting panel 110 and the second connecting panel 120, and the workpiece is disposed within the clamping area.

[0055] Furthermore, the clamping mechanism 200 is disposed on the first connecting panel 110 and the second connecting panel 120. By setting the first connecting panel 110 and the second connecting panel 120 on the base 100 to construct a clamping area, a regular and stable placement space is provided for the workpiece, which facilitates unified clamping and management and improves operational convenience.

[0056] Specifically, multiple evenly distributed elongated slots 130 are formed on the first connecting panel 110 and the second connecting panel 120. Therefore, the clamping mechanism 200 can be positioned on the first connecting panel 110 and the second connecting panel 120 between two adjacent slots 130. It can be understood that by positioning the clamping mechanism 200 on the first connecting panel 110 and the second connecting panel 120 between adjacent slots 130, the structural characteristics of the panels and slots 130 allow for a more uniform distribution of clamping force, effectively improving the fixation of the workpiece and ensuring its stability and preventing displacement during the cutting process.

[0057] Referring to Figures 1 to 7, in one embodiment, the clamping mechanism 200 includes a clamping cylinder 210 and a limiting block 220 connected to the cylinder rod of the clamping cylinder 210. A single clamping mechanism 200 has two clamping cylinders 210, which are respectively connected to the first connecting panel 110 and the second connecting panel 120. The clamping cylinders 210 located on the first connecting panel 110 and the second connecting panel 120 can be symmetrically arranged. By symmetrically arranging the two clamping cylinders 210 on the first connecting panel 110 and the second connecting panel 120, and cooperating with the limiting block 220 to apply force synchronously from both sides, it is ensured that the workpiece is subjected to uniform force during the cutting process, remaining stable and not shaking, effectively improving cutting accuracy and quality.

[0058] Understandably, the workpiece used for cutting is clamped between two limiting blocks 220 disposed on the first connecting panel 110 and the second connecting panel 120.

[0059] Furthermore, to improve the applicability and convenience of this device in actual use, grooves 140 for accommodating the limiting blocks 220 can be respectively provided on the first connecting panel 110 and the second connecting panel 120. When the lever of the clamping cylinder 210 retracts, the limiting block 220 is located in the groove 140. And when the lever of the clamping cylinder 210 extends, the limiting block 220 protrudes from the groove 140, and the workpiece can be clamped between the two limiting blocks 220.

[0060] Understandably, by controlling the extension and retraction of the cylinder rod of the clamping cylinder 210 to move the limiting block 220 into and out of the groove 140, quick clamping and releasing of workpieces can be achieved, simplifying the operation process and significantly shortening the loading and unloading time, thereby improving production efficiency. At the same time, the groove 140 allows the limiting block 220 to be completely retracted when not in use, avoiding interference with other operations, while also being compatible with workpieces of different thicknesses and specifications, broadening the application range of the tooling and meeting diverse processing needs.

[0061] Please refer to Figures 1 to 7. In one embodiment, in order to improve the clamping accuracy of the workpiece, the workpiece can be positioned by the positioning mechanism 300.

[0062] Specifically, the positioning mechanism 300 includes a first positioning block 310 and a second positioning block 320. The first positioning block 310 has a first positioning reference surface 311 and is mounted on the base 100. The first positioning block 310 and the base 100 are detachably fixed together by bolts, facilitating replacement or adjustment of the first positioning block 310. The second positioning block 320 has a second positioning reference surface 321 and is mounted on the first connecting panel 110 and / or the second connecting panel 120. The second positioning block 320 can be integrally formed or separately mounted from the first connecting panel 110 or the second connecting panel 120.

[0063] Understandably, the first positioning block 310 is bolted for detachable connection, facilitating quick replacement or adjustment based on different workpiece sizes and shapes. The second positioning block 320 can be either integrally formed or separately designed, and its flexible angle design allows the tooling to adapt to the positioning needs of various types of workpieces, enhancing the equipment's versatility.

[0064] It should be noted that the first positioning reference surface 311 and the second positioning reference surface 321 are set at an angle. The size of the angle is set based on the specific shape of the workpiece. For example, in one embodiment, the two positioning surfaces of the workpiece used for cutting are set perpendicularly, then the first positioning reference surface 311 and the second positioning reference surface 321 are also set perpendicularly.

[0065] Specifically, in one embodiment, the first positioning block 310 is connected to the base 100, and the first positioning block 310 is provided near both the first connecting panel 110 and the second connecting panel 120. It should be noted that the first positioning reference surface 311 of the two first positioning blocks 310 is on the same horizontal plane.

[0066] To achieve the positioning effect of the second positioning reference surface 321, the limiting block 220 is provided with a wedge-shaped positioning guide surface 211, which is located on the side of the limiting block 220 closest to the second positioning reference surface 321. Therefore, when the limiting blocks 220 on both sides of the workpiece extend through the clamping cylinder 210, the wedge-shaped positioning guide surface 211 allows one side of the workpiece to fit tightly against the second positioning reference surface 321. Furthermore, this effectively ensures the clamping accuracy of the workpiece, thereby improving the subsequent cutting effect.

[0067] Understandably, the positioning mechanism 300, through the cooperation of the reference surfaces of the first positioning block 310 and the second positioning block 320, sets an included angle according to the shape of the workpiece, and cooperates with the wedge-shaped positioning guide surface 211 of the limiting block 220. This effectively ensures that the workpiece is accurately aligned with the positioning reference during clamping, effectively improving clamping accuracy and reducing cutting errors. At the same time, the wedge-shaped positioning guide surface 211 automatically corrects the workpiece position. The operator only needs to activate the clamping cylinder 210 to achieve rapid and accurate positioning and clamping of the workpiece, reducing the difficulty of manual calibration.

[0068] Referring to Figures 1 to 7, in one embodiment, an air distribution block 400, including an air inlet and multiple air outlets, may be provided on the base 100. An external air source module is connected to the air inlet, and the air outlets are respectively connected to the clamping cylinders 210. By providing the air distribution block 400, multiple clamping cylinders 210 can be controlled to work synchronously.

[0069] Based on this, the present invention also provides a multi-wire cutting device, which includes a clamping fixture for multi-wire cutting as described in any of the above embodiments.

[0070] According to the embodiments of this disclosure, the following technical effects are achieved:

[0071] The clamping fixture for multi-wire cutting achieves precise workpiece positioning and stable clamping through the reference surface of the positioning block, the wedge-shaped positioning guide surface 211, and the symmetrically arranged clamping cylinders 210, effectively reducing cutting errors and improving processing accuracy and product quality.

[0072] Meanwhile, the clamping cylinder 210 controls the extension and retraction of the limiting block 220, which, in conjunction with the groove 140 design, enables rapid clamping and unclamping of workpieces, simplifying the operation process and significantly shortening loading and unloading time. Furthermore, the wedge-shaped positioning guide surface 211 automatically corrects the workpiece position, reducing the difficulty of manual calibration and further improving production efficiency.

[0073] This can effectively improve the problems of complex assembly and poor clamping accuracy of multi-wire cutting equipment.

[0074] The specific embodiments described above do not constitute a limitation on the scope of protection of this disclosure. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
