Abstract
Description
Technical Field
[0001] This application relates to the field of wire EDM fixtures, and more specifically, to a special fixture for wire EDM processing. Background Technology
[0002] In the field of machining precision structural parts such as aerospace components that require CNC wire cutting, traditional clamping methods have many drawbacks.
[0003] On the one hand, traditional methods are difficult to achieve precise positioning, and the workpiece is prone to displacement during processing, resulting in difficulty in guaranteeing processing accuracy and a high defect rate; on the other hand, traditional clamping methods have a complex clamping process, which is difficult to meet the needs of mass production and has low processing efficiency.
[0004] Traditional methods rely heavily on manual operation, which makes them prone to errors due to human factors, increases the workload of workers, and results in poor product quality stability.
[0005] Therefore, this application proposes a special fixture for wire EDM to solve the above-mentioned problems.
[0006] Application content
[0007] To address the aforementioned problems, this application provides a special fixture for wire EDM machining.
[0008] The technical solution for a special fixture for wire EDM machining provided in this application is as follows:
[0009] A special fixture for wire EDM machining includes:
[0010] The fixture body includes positioning strips arranged vertically and symmetrically on the front, and a plurality of positioning grooves are evenly provided on the positioning strips;
[0011] A positioning post is also provided between adjacent positioning slots, and the positioning post is longitudinally arranged on the fixture body.
[0012] Furthermore, the positioning post has a detachable structure.
[0013] The above technical solution makes it easy to replace the positioning column, which can restore the high-precision positioning function of the fixture in a timely manner and ensure that the processing always maintains a high level. If the positioning column is accidentally damaged during the processing, the detachable structure allows for quick replacement, avoiding production stoppages caused by waiting for repairs or replacing the entire fixture.
[0014] Furthermore, the positioning strip is also provided with a locking screw that connects to the positioning groove, and the locking screw is used to lock the workpiece.
[0015] Through the above technical solution, during the online cutting process, factors such as machine tool vibration may cause the workpiece to shift. The fastening force provided by the locking screw effectively prevents such situations from occurring, ensuring that the workpiece remains stable throughout the processing, reducing processing errors caused by workpiece shifting, and significantly improving processing quality.
[0016] Furthermore, the locking screw is located on the front of the positioning strip and the threaded hole is a countersunk hole.
[0017] With the above technical solution, when clamping workpieces, operators can directly and quickly operate the locking screws from the front without complicated operating postures or additional tool adjustments, which significantly improves clamping efficiency; the countersunk hole design prevents the screw head from protruding from the surface of the positioning strip, preventing scratches on the workpiece surface during clamping or processing and protecting the appearance quality of the workpiece.
[0018] Furthermore, the back of the fixture body is provided with operating grooves on both sides, and the bottom of the operating groove is provided with a vertically downward U-shaped groove with an opening facing backward. A bolt post is detachably installed in the U-shaped groove, and the bolt post is used to fix the fixture body.
[0019] Through the above technical solution, the operating grooves on both sides of the back of the fixture body provide operators with convenient gripping and force application areas, reducing the difficulty and labor intensity of operation when installing the fixture onto or removing it from the machine tool worktable; the U-shaped groove at the bottom of the operating groove is vertically downward and opens to the rear, with removable bolt posts inside for fixing the fixture body. This design not only ensures the fixture is firmly fixed on the machine tool worktable and can effectively resist vibration during processing, but also facilitates flexible disassembly and reinstallation of the fixture according to processing needs, improving the convenience of fixture use and optimizing the entire processing flow.
[0020] Furthermore, the positioning pin is installed from the back of the fixture body from back to front.
[0021] With the above technical solution, the positioning pin is installed from the back of the fixture body from back to front, which is convenient for installation and operation, and can also prevent workpiece damage caused by positioning pin problems during processing due to the stable connection.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] (1) Through the coordinated operation of positioning bars, positioning grooves, positioning pins and locking screws, the workpiece is accurately positioned and securely clamped, effectively reducing the generation of defective products and ensuring stable and reliable product quality in mass production.
[0024] (2) The clamping method is quick and convenient, and multiple workpieces can be clamped at one time, which is suitable for batch processing and production, greatly improving processing efficiency and reducing the labor intensity of workers. Attached Figure Description

[0032] Example:
[0033] The following is in conjunction with the appendix Figure 1 -3 provides further detailed description of this application.
[0034] This application discloses a special fixture for wire EDM machining, including:
[0035] The fixture body 1 includes positioning strips 2 arranged vertically and symmetrically on the front, and a plurality of positioning grooves 3 are evenly provided on the positioning strips 2.
[0036] A positioning post 4 is also provided between adjacent positioning slots 3, and the positioning post 4 is longitudinally arranged on the fixture body 1.
[0037] See Figure 1 , Figure 2 and Figure 3 The positioning post 4 has a detachable structure; the detachable feature makes it easy to replace the positioning post 4, and can restore the high-precision positioning function of the fixture in a timely manner, ensuring that the processing always maintains a high level; if the positioning post 4 is accidentally damaged during the processing, the detachable structure allows for quick replacement, avoiding production stoppages caused by waiting for repairs or replacing the entire fixture.
[0038] See Figure 1 and Figure 2 The positioning bar 2 is also equipped with a locking screw 5 that connects to the positioning groove 3. The locking screw 5 is used to lock the workpiece. During the wire cutting process, factors such as machine tool vibration may cause the workpiece to shift. The fastening force provided by the locking screw 5 effectively prevents such situations from occurring, ensuring that the workpiece remains stable throughout the processing, reducing processing errors caused by workpiece shifting, and significantly improving processing quality.
[0039] See Figure 1 and Figure 2 The locking screw 5 is located on the front of the positioning strip 2 and the threaded hole is a countersunk hole.
[0040] With the above technical solution, when clamping the workpiece, the operator can directly and quickly operate the locking screw 5 from the front without complicated operating posture or additional tool adjustment, which significantly improves clamping efficiency; the countersunk hole design prevents the screw head from protruding from the surface of the positioning strip 2, preventing scratches on the workpiece surface during clamping or processing and protecting the appearance quality of the workpiece.
[0041] See Figure 1 , Figure 2 and Figure 3The fixture body 1 has operating grooves 6 on both sides of its back. The bottom of the operating grooves 6 has a vertically downward-facing and rearward-opening U-shaped groove 7. A bolt post 8 is detachably installed in the U-shaped groove 7 to fix the fixture body 1. The operating grooves 6 on both sides of the back of the fixture body 1 provide the operator with a convenient grip and force application area, reducing the difficulty and labor intensity when installing the fixture onto or removing it from the machine tool table. The U-shaped groove 7 at the bottom of the operating groove 6 is vertically downward-facing and rearward-opening, and the bolt post 8 inside is detachably installed to fix the fixture body 1. This design not only ensures the fixture is firmly fixed on the machine tool table and can effectively resist vibration during processing, but also facilitates flexible disassembly and reinstallation of the fixture according to processing needs, improving the convenience of fixture use and optimizing the entire processing flow.
[0042] The implementation principle of a special fixture for wire EDM in this application embodiment is as follows: When using the fixture, the fixture is first fixed firmly to the machine tool worktable by using the bolt column 8 in the U-shaped groove 7 at the bottom of the operating groove 6 on the back of the fixture body 1.
[0043] Next, the workpiece is inserted into the positioning groove 3 of the positioning strip 2 from the side, so that the bottom of the workpiece is in close contact with the positioning post 4 to achieve initial positioning; the operator uses the locking screw 5 to firmly lock the workpiece in the positioning groove 3 from the front of the positioning strip 2 to complete the clamping.
[0044] When wire EDM is performed on a machine tool, the fixture, with its precise positioning and stable clamping structure, ensures that the workpiece remains in a fixed position during the machining process, thereby achieving high-precision wire EDM.
[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
