Therefore, the drawings and description are considered exemplary in nature and not restrictive.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] Example:

[0035] See Figure 1 and Figure 2 This embodiment discloses a fixture for an electrical discharge wire cutting device, including a housing 10, a rotor 20, a movable clamp 30, and a limiting assembly 40. The rotor 20 is rotatably mounted on the housing 10 and is located at one corner of the top surface of one side of the housing 10. One end of the rotor 20 is a clamping part 21 for clamping metal raw materials.

[0036] An arc-shaped groove 11 is provided on the housing 10. The groove 11 is located on the side of the housing 10 where the rotor 20 is mounted, and the center of the groove 11 is located on the rotation axis of the rotor 20. The aforementioned movable clamp 30 is slidably mounted on the groove 11, and one end of the movable clamp 30 is inserted into the housing 10.

[0037] A limiting component 40 is installed inside the housing 10. The limiting component 40 is connected to the movable clamp 30, and the limiting component 40 can directly drive the movable clamp 30 to slide in the slide groove 11. At the same time, the limiting component 40 can also fix the movable clamp 30 at any position in the slide groove 11.

[0038] Preferably, the arc of the groove 11 is equal to 90°, and one end of the groove is directly below the rotor 20, while the height of the other end is the same as the height of the rotor 20, so that the rotor 20, in conjunction with the movable clamp 30, can directly control the metal raw material to switch within any angle between the horizontal and vertical directions.

[0039] The working principle of this embodiment is as follows: a housing 10 is set up, the rotor 20 is rotatably mounted on the housing 10, and the metal raw material is clamped by the clamping part 21 on the rotor 20 and clamped on the movable clamp 30. Then, the position of the movable clamp 30 is adjusted by the limiting component 40, thereby driving the rotor 20 to rotate and driving the metal raw material to rotate. When the metal raw material rotates to the required angle, the position of the movable clamp 30 is fixed by the limiting component 40, and then processing is performed.

[0040] This technical solution utilizes a simple fixture structure to achieve the purpose of wire electrical discharge cutting of metal raw materials at an angle. At the same time, the control method of the fixture is very simple.

[0041] It should also be noted that appropriate counterweights need to be installed on the outside of the housing 10 to ensure that the clamp can support the metal material after it is clamped.

[0042] In one specific embodiment:

[0043] The clamping part 21 has an embedding groove, and the rotor 20 is provided with a locking bolt that can enter the embedding groove. The structure of the drive part is the same as that of the clamping part 21.

[0044] When clamping metal raw materials, the metal raw materials are installed in the embedding grooves of the rotor 20 and the movable clamp 30, and then the metal raw materials are locked by the locking bolts on the rotor 20 and the movable clamp.

[0045] Generally, in order to ensure the stability of metal raw materials during processing, two clamps are used symmetrically on both sides of the metal raw materials.

[0046] In another specific embodiment:

[0047] The housing 10 is provided with a connecting plate 50 that connects the rotor 20 and the movable clamp 30. By setting the connecting plate 50, the movable clamp 30 and the rotor 20 can always maintain a suitable angle, which makes it easy to clamp metal raw materials.

[0048] In another specific embodiment:

[0049] The limiting assembly 40 includes a drive block 41, a drive shaft 42, a limiting rod 43, a screw 44, a support block 45, and a bevel gear 46. The drive block 41 is horizontally positioned within the housing 10 and can reciprocate vertically within it. The drive block 41 has a drive groove 47 in its center, the length of which is greater than the radius of the corresponding slide groove 11. The projections of both ends of the slide groove 11 onto the drive groove 47 are located inside the drive groove 47. One end of the movable clamp 30, which penetrates the housing 10, is located within the drive groove 47.

[0050] A limiting rod 43 is provided on each side inside the housing 10, and a limiting hole is provided at each end of the driving block 41. The limiting rod 43 is slidably disposed in the limiting hole.

[0051] The drive block 41 has a connecting part that protrudes away from the rotor 20 in the middle. The connecting part has a threaded hole. The drive shaft 42 is poweredly connected to a screw 44, and the screw 44 matches the threaded hole.

[0052] The support block 45 is disposed inside the housing 10. The support block 45 is rotatably connected to the top end of the screw 44. The bottom end of the screw 44 is rotatably disposed at the bottom of the housing 10. In addition, a bevel gear 46 is provided at the top end of the screw 44. A bevel gear 46 is also provided on the aforementioned drive shaft 42. The two bevel gears 46 mesh with each other.

[0053] The drive shaft 42 is poweredly connected to the drive block 41 through a bevel gear 46, a screw 44 and a connecting part, and is used to drive the drive block 41 to reciprocate in the vertical direction;

[0054] The drive shaft 42 is located inside the housing 10, with one end of the drive shaft 42 inside the housing 10 and the other end outside the housing 10. The drive shaft 42 and the housing 10 are rotatably connected by a bearing. In addition, a hexagonal countersunk hole is provided on the end of the drive shaft 42 located outside the housing 10.

[0055] In this embodiment, the drive shaft 42 is rotated using a tool such as a hex wrench. This rotation, via the bevel gear 46 on the drive shaft 42 and the bevel gear 46 on the screw 44, drives the screw 44 to rotate. The screw 44, in turn, moves vertically through the threaded connection between itself and the connecting part. The connecting part is mounted on the drive block 41. Because the drive block 41 has limit rods 43 at both ends, it can only move vertically within the housing 10. At this time, the sliding groove 11 and the drive groove 47 restrict the position of the movable clamp 30, causing it to move within these grooves and changing its position. Due to the action of the connecting plate 50, the movable clamp 30 also rotates during its movement.

[0056] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
