They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0022] In addition, the terms "horizontal" and "vertical" do not mean that the components must be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Some implementation methods of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 7 As shown, the valve body port wire cutting fixture described in the utility model includes a positioning plate 1, a rotating shaft 2, a side stop positioning block 3, and a rotating fixing screw 4. The positioning plate 1 is square and is used for overall positioning. A positioning step 11 is provided on the positioning plate 1. When connected to the wire cutting machine, the positioning step 11 plays a role in connection positioning, which facilitates the installation and positioning of the fixture.

[0026] The rotating shaft 2 is semi-cylindrical as a whole and is used to position the wire-cut product. A clamping portion 5 is provided at the front end thereof, and a rear end is provided on the positioning plate 1. The clamping portion 5 includes a fixed lower clamping portion and a movable upper clamping portion, and a positioning hole 10 is provided between the upper clamping portion and the lower clamping portion. A fastening screw 13 is provided on the holding portion 5, and the fastening screw 13 is used to connect the upper holding portion and the lower clamping portion to clamp the wire-cut product. The rotating fixing screw 4 is connected to the rear end of the rotating shaft 2, and the rotating fixing screw 4 can adjust the rotating shaft 2 on the positioning plate 1 from a horizontal position to a vertical position. Preferably, a blind hole 7 is provided on the positioning plate 1, and the blind hole 7 is 3 / 4 circular. The rear end of the rotating shaft 2 is provided in the blind hole 7, and the rotating shaft 2 can be rotated 90° in the blind hole 7, that is, from a horizontal position to a vertical position. A waist-shaped through hole 8 may also be provided in the blind hole 7, the trajectory of the waist-shaped through hole 8 is consistent with the rotation arc of the rotating shaft 2, and the rotating fixing screw 4 is connected to the rear end of the rotating shaft 2 through the waist-shaped through hole 8. A limiting boss 6 for preventing the wire cutting product from rotating is also provided on the rotating shaft 2, and the limiting boss 6 is adjacently provided on the inner side of the clamping portion 6, and a groove is provided in the middle of the limiting boss 6.

[0027] The side stopper 3 is connected to the front end of the rotating shaft 2 by connecting screws 9. A notch 14 is provided on the side of the side stopper 3 facing the rotating shaft 2, and the notch 14 is aligned with the positioning hole 10. During wire cutting, the side stopper 3 is used to position the front and rear directions of the wire cutting product.

[0028] The working principle of the utility model is as follows: loosen the fastening screw 13 on the clamping part 5 of the rotating shaft 2, put the wire cutting end of the valve 12 into the positioning hole 10 of the rotating shaft 2, so that the wire cutting end face of the valve contacts the side stop positioning block 3, and the threaded surfaces on both sides contact the limiting boss 6 on the rotating shaft 2. Tighten the fastening screw 13 so that the clamping part 5 clamps the valve 12. Loosen the rotating fixing screw 4, rotate the rotating shaft 2 to a horizontal position, tighten the rotating fixing screw 4, and start the wire cutting machine to perform the first wire cutting. After the first wire cutting is completed, loosen the rotating fixing screw 4, rotate the rotating shaft 2 to a vertical position, tighten the rotating fixing screw 4 again, and start the wire cutting machine to perform the second wire cutting. After the second wire cutting is completed, loosen the fastening screw 13 and remove the valve 12 from the clamping part 5 of the rotating shaft 2.

[0029] It should be noted that the rotating shaft 2 can be provided in multiple groups, that is, multiple groups of blind holes 7 are provided on the positioning plate 1, so as to realize one-time clamping and multi-station processing, which greatly improves the efficiency of wire cutting. At the same time, the rotating shaft 2 can be replaced according to the size of the wire cutting product, which increases the application scope of the utility model.
