Abstract
Description
Technical Field
[0001] This application relates to the technical field of machining positioning fixtures, and in particular to a wire EDM machining large-angle positioning fixture. Background Technology
[0002] like Figure 1 As shown, this application describes a serrated metal cutter with a serrated cutting edge in the middle section. The cutting edge angle is 45°, resulting in a cutting angle of -135°. Because of the serrated cutting edge, it cannot be ground using a machining center and must be produced using a laser cutting machine or a wire cutting machine. While a laser cutting machine can meet the processing requirements, its cost is too high. Although a wire cutting machine is cheaper, adjusting the molybdenum wire angle too much during large-angle cutting can cause the wire to derail, thus failing to meet the requirements for large-angle cutting. Utility Model Content
[0003] To address the aforementioned technical problems, this application provides a large-angle positioning fixture for wire EDM, which has the advantage of meeting the usage requirements of large-angle wire EDM.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A wire EDM machining fixture for large-angle positioning includes a positioning plate with a positioning groove for inserting a product. The positioning groove is inclined, and the positioning plate is provided with a positioning element for pressing the product into the positioning groove.
[0005] To achieve the above technical solution, after the product is inserted into the positioning groove and fixed in the positioning groove by the positioning component, the positioning groove itself is inclined so that the blade above the positioning plate is tilted after it is inserted into the positioning groove. Therefore, the actual cutting angle is reduced, thereby meeting the requirements of wire cutting and ensuring normal cutting.
[0006] As a preferred embodiment of this application, the positioning element includes a pair of positioning screws screwed onto the positioning plate, the positioning screws extending into the positioning groove, and a washer provided at one end of the positioning screw in the positioning groove.
[0007] The above technical solution is achieved by dropping the positioning screw into the positioning groove, thereby pressing the product into the positioning groove and fixing the product. In order to prevent crushing, a gasket is provided at one end of the positioning screw in the positioning groove so that the gasket can play a buffering and protective role.
[0008] As a preferred embodiment of this application, it also includes an angle adjustment component for adjusting the angle of the positioning plate.
[0009] As a preferred embodiment of this application, the angle adjustment component includes a bracket, a rotating shaft is provided on the positioning plate, the rotating shaft is rotatably mounted on the bracket, and a rotation adjustment component for driving the rotating shaft to rotate is provided on the bracket.
[0010] The above technical solution is achieved by driving the rotating shaft to rotate through the rotating adjustment component, which in turn drives the positioning plate on the rotating shaft to rotate, thereby adjusting the tilt angle of the positioning plate.
[0011] As a preferred embodiment of this application, the rotating adjustment component includes a worm gear rotatably mounted on a bracket, a worm wheel that engages with the worm gear transmission on the rotating shaft, and an adjustment wheel at the end of the worm gear.
[0012] The above technical solution is achieved by using the adjusting wheel to drive the worm gear to rotate, which in turn drives the rotating shaft to rotate, thereby fulfilling the need to adjust the angle of the positioning plate. At the same time, because the structure of the worm gear itself has a self-locking function, the stability after adjustment is ensured.
[0013] As a preferred embodiment of this application, an angle indicator is provided on the rotating shaft, and an angle indicator scale is provided on the side bracket of the rotating shaft.
[0014] The above technical solution is implemented to monitor the tilt angle of the current positioning plate in real time, thereby ensuring the angle of the product on it.
[0015] In summary, this application includes at least one of the following beneficial technical effects: After the product is inserted into the positioning groove and fixed in the positioning groove by the positioning component, the positioning groove itself is inclined so that the blade above the positioning plate is tilted after it is inserted into the positioning groove. Therefore, the actual cutting angle is reduced, which meets the requirements of wire cutting and ensures the normality of cutting. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0022] This application discloses a positioning fixture for large-angle wire EDM machining. (Refer to...) Figure 2 The wire EDM (Electrical Discharge Machining) large-angle positioning fixture includes a positioning plate 1. The positioning plate 1 has a positioning groove 11 for inserting the product. The positioning groove 11 is inclined, and the positioning plate 1 has a positioning element for pressing the product into the positioning groove 11. After the product is inserted into the positioning groove 11 and fixed thereby by the positioning element, the inclined positioning groove 11 causes the cutting edge above the positioning plate 1 to tilt, thus reducing the actual cutting angle and meeting the requirements of wire EDM, thereby ensuring normal cutting.
[0023] The positioning component includes a pair of positioning screws 12 screwed onto the positioning plate 1. The positioning screws 12 extend into the positioning groove 11. By dropping the positioning screws 12 into the positioning groove 11, the product is pressed into the positioning groove 11, thereby completing the product fixation. To prevent damage from pressure, a washer 13 is provided at one end of the positioning screw 12 in the positioning groove 11, so that the washer 13 has a buffering and protective effect.
[0024] To meet the need for a wider range of cutting angles, the wire EDM large-angle positioning fixture also includes an angle adjustment component 2 for adjusting the angle of the positioning plate 1. The angle adjustment component 2 can be a commonly available rotary cylinder or a hinged electric telescopic cylinder. In this embodiment, the angle adjustment component 2 includes a bracket 21, a rotating shaft 22 is mounted on the positioning plate 1, the rotating shaft 22 is rotatably mounted on the bracket 21, and a rotation adjustment component is mounted on the bracket 21 to drive the rotating shaft 22 to rotate. That is, the rotation adjustment component drives the rotating shaft 22 to rotate, thereby causing the positioning plate 1 on the rotating shaft 22 to rotate, thus adjusting the tilt angle of the positioning plate 1.
[0025] The rotating adjustment component includes a worm gear 23 rotatably mounted on a bracket 21, a worm wheel 24 on a rotating shaft 22 that drives the worm gear 23, and an adjusting wheel 25 at the end of the worm gear 23. That is, when the adjusting wheel 25 drives the worm gear 23 to rotate, it drives the worm wheel 24 to rotate, thereby achieving the effect of rotating the rotating shaft 22, thus fulfilling the requirement of adjusting the angle of the positioning plate 1. Simultaneously, because the structure of the worm wheel 24 and the worm gear 23 itself has a self-locking function, the stability after adjustment is ensured. An angle indicator 26 is provided on the rotating shaft 22, and an angle indicator scale 27 is provided on the side bracket 21 of the rotating shaft 22 for real-time observation of the current tilt angle of the positioning plate 1, thereby ensuring the angle of the product on it.
[0026] The implementation principle of a large-angle positioning fixture for wire EDM in this embodiment is as follows: After the product is inserted into the positioning groove 11 and fixed in the positioning groove 11 by the positioning component, the positioning groove 11 is inclined, so the cutting edge above the positioning plate 1 is tilted after it is inserted into the positioning groove 11, thus reducing the actual cutting angle and meeting the requirements of wire EDM, thereby ensuring normal cutting. When the adjusting wheel 25 drives the worm gear 23 to rotate, it drives the worm wheel 24 to rotate, thereby driving the rotating shaft 22 to rotate, thus achieving the requirement of adjusting the angle of the positioning plate 1.
[0027] 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.
