Description

Technical Field

[0001] This utility model relates to tooling fixtures, and in particular to a tooling fixture for wire EDM products, belonging to the field of auxiliary tooling technology for cutting processes. Background Technology

[0002] Wire EDM product tooling fixtures are specialized devices that assist in wire EDM processing. They can accurately position and reliably clamp workpieces, thereby ensuring processing accuracy, improving production efficiency, and ensuring stable quality of wire EDM products.

[0003] Publication number CN219766999U discloses a wire EDM machining fixture, comprising: a fixed fixture, a replaceable fixture, and a fixing block; the fixing block secures materials to the replaceable fixture to form a replaceable assembly; the fixture operates as follows: First, materials are placed on the replaceable fixture, multiple materials are clamped by baffles and the fixing block, and the replaceable fixture and the fixing block are fastened together with screws to form a replaceable assembly; Second, the replaceable assembly is installed inside the fixed fixture, with a first groove and a second groove providing a wire EDM path to cut the materials into products; Third, the replaceable assembly is then removed, the screws are turned to loosen the fixing block, the product is poured out, and the materials are placed back on the replaceable fixture, repeating the above operation; this fixture allows for quick clamping of small-sized products, and after processing, only the replaceable assembly needs to be changed to continue processing, improving production efficiency.

[0004] As described above, traditional wire EDM fixtures are mostly fixed structures. This can easily lead to instability when clamping irregular workpieces due to limited force points, causing workpiece displacement during wire EDM and affecting machining accuracy. Furthermore, traditional fixtures lack angle adjustment capabilities, only allowing for planar cutting. When angle machining of the wire EDM cutting edge is required, multiple clamping and adjustment of the workpiece position are necessary. This is not only cumbersome and inefficient, but also results in cumulative errors due to repeated clamping, impacting machining accuracy and production efficiency. Improvements are needed to address these issues.

[0005] To address this, a tooling fixture for wire EDM products is proposed. Utility Model Content

[0006] In view of this, the present invention provides a tooling fixture for wire EDM products to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A wire cutting product tooling fixture includes a mounting plate and a base plate. An inner plate is installed on the top of the mounting plate, and an arc-shaped plate is sleeved on the inner plate. An arc-shaped guide groove is provided in the arc-shaped plate. A motor is installed on the inner plate, and a friction wheel is installed at the output end of the motor. A support plate is installed on the top of the arc-shaped plate. There are two sets of support plates, and a threaded rod is rotatably installed in one set of support plates. A guide rod is also installed in the support plate. A connecting block A and a connecting block B are installed below the other set of support plates. There are two sets of base plates, which are fixedly connected to the top of the support plates. Multiple sets of screws are threadedly connected to the base plates. A vertically penetrating positioning hole is provided in the base plates. A positioning rod is installed on the support plate, and a locking nut is threadedly connected to the positioning rod.

[0008] More preferably, the arc-shaped plate is slidably mounted on the inner plate via an arc-shaped guide groove.

[0009] More preferably, the connecting block B is provided with a threaded groove, and the connecting block B and the threaded rod are connected by a thread.

[0010] More preferably, the connecting block A is slidably mounted on the guide rod, and a crank handle is provided at one end of the threaded rod.

[0011] More preferably, the number of the mounting plate, inner plate, arc plate, motor and friction wheel are all two sets, and the arc plate located below the connecting block A and the connecting block B is provided with a sliding groove, and the connecting block A and the connecting block B are slidably disposed in the sliding groove.

[0012] More preferably, the friction wheel is in contact with the arc-shaped plate, and the friction wheel is made of rubber.

[0013] More preferably, the locking nut is located above the substrate.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. In this utility model, by setting an array of screws on the base plate, the screw insertion depth can be adjusted according to the shape of the workpiece, thereby changing its length extending beyond the base plate. This design enables efficient clamping based on the workpiece's outline, increases effective force points, and effectively ensures the stability of irregular workpieces assembled on the fixture, avoiding workpiece displacement due to wire slip during processing and affecting machining accuracy. Furthermore, the base plate and support plate adopt a modular connection, allowing for multiple combinations through the cooperation of positioning rods and different positioning holes, significantly improving flexibility.

[0016] II. In this utility model, by setting a mounting plate, an inner plate, an arc-shaped plate, a motor, and a friction wheel below the base plate, when the motor is working, the friction between the friction wheel and the wall of the arc-shaped plate drives the arc-shaped plate to adjust its position along the arc-shaped guide groove of the inner plate, thereby precisely driving the fixture and workpiece above to achieve angle adjustment. This structure facilitates the cutting edge processing of wire EDM and breaks through the limitations of traditional wire EDM in planar cutting.

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, this utility model embodiment provides a wire EDM product tooling fixture, including a mounting plate 1 and a base plate 8. An inner plate 2 is mounted on the top of the mounting plate 1, and an arc-shaped plate 3 is sleeved on the inner plate 2. An arc-shaped guide groove 4 is provided in the arc-shaped plate 3. A motor 5 is mounted on the inner plate 2, and a friction wheel 6 is mounted on the output end of the motor 5. A support plate 7 is mounted on the top of the arc-shaped plate 3. There are two sets of support plates 7, and a threaded rod 9 is rotatably mounted in one set of support plates 7. A guide rod 10 is also mounted in the support plate 7. A connecting block A11 and a connecting block B12 are mounted below the other set of support plates 7. There are two sets of base plates 8 and they are fixedly connected above the support plates 7. Multiple sets of screws 14 are threadedly connected to the base plates 8. A vertically penetrating positioning hole 15 is provided in the base plates 8. A positioning rod 16 is mounted on the support plates 7, and a locking nut 17 is threadedly connected to the positioning rod 16.

[0027] In one embodiment, the arc-shaped plate 3 is slidably mounted on the inner plate 2 via the arc-shaped guide groove 4. Because the friction wheel 6 is in contact with the wall of the arc-shaped plate 3, the arc-shaped plate 3 slides along the arc-shaped guide groove 4 of the inner plate 2 under the action of friction.

[0028] In one embodiment, the connecting block B12 is provided with a threaded groove, and the connecting block B12 is connected to the threaded rod 9 by a thread. When the threaded rod 9 rotates, the connecting block B12 moves axially along the threaded rod 9 under the action of the thread, and the connecting block A11 slides smoothly along the guide rod 10 at the same time.

[0029] In one embodiment, the connecting block A11 is slidably mounted on the guide rod 10, and a crank handle is provided at one end of the threaded rod 9. The crank handle facilitates the rotation of the threaded rod 9, thereby facilitating the assembly of the workpiece.

[0030] In one embodiment, the number of mounting plate 1, inner plate 2, arc plate 3, motor 5 and friction wheel 6 are all two sets, and a sliding groove 13 is provided on one set of arc plate 3 located below connecting block A11 and connecting block B12, and connecting block A11 and connecting block B12 are slidably disposed in the sliding groove 13.

[0031] In one embodiment, the friction wheel 6 is in contact with the arc-shaped plate 3, and the friction wheel 6 is made of rubber. Under the action of friction, the arc-shaped plate 3 slides along the arc-shaped guide groove 4 of the inner plate 2, while the arc-shaped plate 3 drives the upper support plate 7 and the clamped workpiece to move synchronously.

[0032] In one embodiment, the locking nut 17 is located above the base plate 8. By rotating the locking nut 17 on the positioning rod 16, the locking nut 17 is tightly attached to the top of the base plate 8 through threaded engagement, thereby achieving a stable connection between the base plate 8 and the support plate 7.

[0033] In operation, this invention first assembles two sets of base plates 8 and support plates 7. The positioning rod 16 on the support plate 7 is inserted into the corresponding positioning hole 15 on the base plate 8. The locking nut 17 on the positioning rod 16 is rotated, and through threaded engagement, the locking nut 17 is tightly fitted against the top of the base plate 8, achieving a stable connection between the base plate 8 and the support plate 7. Then, according to the outline of the workpiece, the threaded screws 14 on the base plate 8 are rotated one by one. Under the action of the threads, the screws 14 change the depth of their insertion into the base plate 8, thereby adjusting their length extending beyond the outer side of the base plate 8, until the ends of all sets of screws 14 are in contact with the workpiece surface. Through the adaptation and adjustment of multiple sets of screws 14, the effective force points of the workpiece and the fixture are increased, ensuring the workpiece is tightly clamped between the two sets of base plates 8. This prevents workpiece displacement due to wire cutting force during subsequent wire cutting, ensuring workpiece assembly stability and processing accuracy.

[0034] When it is necessary to perform angle machining on the wire EDM cutting edge, the motor 5 on the inner plate 2 is started, and the output end of the motor 5 drives the friction wheel 6 to rotate. Since the friction wheel 6 is in contact with the wall of the arc plate 3, under the action of friction, the arc plate 3 slides along the arc guide groove 4 of the inner plate 2. At the same time, the arc plate 3 drives the support plate 7 above and the clamped workpiece to move synchronously, realizing the precise adjustment of the workpiece machining angle, breaking through the limitations of traditional planar cutting, and meeting the special angle machining requirements such as the cutting edge. If it is necessary to adapt to workpieces of different sizes, the threaded rod 9 in one set of support plates 7 can be rotated: because the connecting block B12 below the other set of support plates 7 is connected to the threaded rod 9 by threads, and the connecting block A11 is slidably set on the guide rod 10, when the threaded rod 9 rotates, under the action of the threads, it drives the connecting block B12 to move along the axial direction of the threaded rod 9, and the connecting block A11 slides smoothly along the guide rod 10 at the same time, thereby driving the corresponding support plate 7 and base plate 8 to move, adjusting the distance between the two sets of base plates 8, adapting to workpieces of different widths or sizes, and improving the versatility and machining adaptability of the fixture.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
