Description

Technical Field

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

[0002] In the mechanical manufacturing process, clamping devices are usually used to fix the workpiece in place to ensure that it is in the correct position for processing.

[0003] Currently, in wire EDM, clamping devices are typically used to secure workpieces made up of multiple stacked thin sheet metals. Most existing clamping devices include a base plate with two sets of opposing clamping blocks. The workpiece is placed between the two sets of clamping blocks, and then the clamping blocks at both ends of the workpiece are locked to clamp it, facilitating subsequent cutting. However, the clamping blocks on both sides of the aforementioned clamping devices only apply pressure to the sides of the workpiece, while the middle of the workpiece lacks support and constraint. This results in uneven force distribution in the middle of the workpiece, causing deformation and warping, which affects the accuracy of wire EDM and reduces the production quality of the workpiece.

[0004] Therefore, there is an urgent need for a clamping device for wire EDM to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a clamping device for wire EDM to solve the problem that the middle part of the workpiece is easily lifted when the existing clamping device is clamped, which affects the accuracy of wire EDM.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0031] In one embodiment of this utility model, such as Figure 1-5 As shown, a clamping device for wire EDM is provided, including a base plate 10, a clamping assembly, a pressing assembly, and a conductive assembly 40. The base plate 10 has a clamping station for placing a workpiece. The clamping assembly includes two sets of clamping components 20. The two sets of clamping components 20 are respectively disposed on both sides of the clamping station for clamping both sides of the workpiece. The pressing assembly is disposed on the clamping station and spans the clamping assembly. The pressing assembly includes a first pressing component 30 and a second pressing component 31. The first pressing component 30 is slidably disposed within the clamping station. The second pressing component 31 is slidably disposed within the first pressing component 30 and is disposed opposite to the first pressing component 30. The conductive assembly 40 is disposed on the base plate 10 and located at one end of the clamping assembly for conducting current on the workpiece.

[0032] By setting up clamping and pressing components, the workpiece is placed on the clamping station and pressed by the clamping components 20 at both ends of the workpiece. Then, the position of the first pressing component 30 is adjusted to be close to the position of the workpiece to be processed. Then, the adjusting screw 313 is rotated to adjust the relative position between the first pressing component 30 and the second pressing component 31, so that the first pressing component 30 and the second pressing component 31 press the middle of the workpiece, preventing the middle of the workpiece from lifting due to uneven force, improving the accuracy of wire cutting, and thus improving the production quality of the workpiece.

[0033] Preferably, the first clamping component 30 includes a support frame 302 and a first clamping block 301. The support frame 302 is slidably disposed on the clamping station. The first clamping block 301 is disposed at the bottom end of the support frame 302 and located below the clamping station. By slidably disposing the support frame 302 on the clamping station and the first clamping block 301 being disposed at the bottom end of the support frame 302, and cooperating with the second clamping component 31, the workpiece is stably clamped between the first clamping component 30 and the second clamping component 31, preventing the workpiece from lifting due to uneven force in the middle, thus improving the accuracy of wire cutting. At the same time, the slidable placement of the support frame 302 on the clamping station facilitates adjustment of the workpiece's required clamping position, thereby improving the workpiece clamping effect.

[0034] Furthermore, the support frame 302 includes a top support plate 302a, a bottom support plate 302b, and two sets of side support plates 302c. The two sets of side support plates 302c extend from the bottom plate 10 and are located on either side of the clamping station. The top two ends of the top support plate 302a are connected to the top ends of the side support plates 302c. The bottom two ends of the bottom support plate 302b are connected to the bottom ends of the side support plates 302c, and the first clamping block 301 is located on the bottom end of the support. The support frame 302, composed of the top support plate 302a, the bottom support plate 302b, and the two sets of side support plates 302c, forms a frame-like structure, improving the overall structural stability of the support frame 302 and thus enhancing the workpiece clamping effect.

[0035] Furthermore, the second clamping component 31 includes a supporting connecting plate 311 and a second clamping block 312. The supporting connecting plate 311 is connected at both ends to the supporting side plate 302c and is located below the supporting top plate 302a. An adjusting screw 313 is provided between the supporting connecting plate 311 and the supporting top plate 302a. Rotating the adjusting screw 313 causes the second clamping block 312 to move downwards, adjusting the relative position between the first clamping block 301 of the first clamping component 30 and the second clamping block 312 of the second clamping component 31. This allows the first clamping component 30 and the second clamping component 31 to clamp the center of the workpiece, preventing the center of the workpiece from warping due to uneven force, improving the accuracy of wire cutting, and thus improving the production quality of the workpiece.

[0036] Furthermore, a spring 314 is provided between the support connecting plate 311 and the support side plate 302c. By providing the spring 314, when the adjusting screw 313 is loosened upwards, it is easy for the second clamping block 312 to reset.

[0037] Preferably, the clamping component 20 includes a clamping block 21 and multiple sets of limiting blocks 22. The clamping block 21 is disposed on the base plate 10. The clamping block 21 is provided with a first adjusting groove 211, which is connected to the base plate 10 by a first screw. Multiple sets of limiting blocks 22 are equally spaced on the base plate 10, and each limiting block 22 is provided with a second adjusting groove 221. The second adjusting groove 221 is connected to the base plate 10 by a second screw. When clamping the workpiece, the limiting blocks 22 are used to initially position the workpiece, and then the clamping blocks 21 clamp both sides of the workpiece, thereby achieving clamping at both ends of the workpiece. At the same time, by providing the first adjusting groove 211 and the second adjusting groove 221, the position adjustment of the clamping block 21 and the limiting blocks 22 is facilitated, which can adapt to workpieces of different sizes and shapes and improve the versatility of the clamping device.

[0038] Specifically, the clamping block 21 includes a support block 212 and a gripper 213. The support block 212 is disposed on the base plate 10 and located outside the limiting block 22. The gripper 213 is rotatably connected to the support block 212. A first adjusting groove 211 is located on the gripper 213. By rotatably connecting the gripper 213 to the support block 212, the gripper 213 can flexibly clamp the workpiece to accommodate workpieces of different sizes and shapes.

[0039] Furthermore, the gripper 213 has an arc-shaped portion corresponding to the support block 212. The limiting block 22 has a rotating groove corresponding to the arc-shaped portion. By setting the arc-shaped portion and the rotating groove, the position and angle of the gripper 213 can be easily adjusted to accommodate workpieces of different sizes and shapes.

[0040] Preferably, the conductive assembly 40 includes a conductive mounting base 41 and a conductive element 42. The conductive mounting base 41 is disposed on the base plate 10. The conductive element 42 is disposed on the conductive mounting base 41, and the conductive element 42 has an outwardly protruding pointed corner 43 at one end near the workpiece. By providing the pointed corner 43, during processing, the pointed corner 43 always abuts against the two side walls of the workpiece, ensuring stable current conduction to the workpiece. This improves the production quality of wire EDM.

[0041] Preferably, the base plate 10 is provided with a centering hole 11. By providing the centering hole 11, it is convenient for the operator to perform workpiece positioning and centering operations during the processing, thereby improving the processing accuracy and efficiency of wire EDM.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
