Description

Technical Field

[0001] This invention relates to the field of inspection tooling technology for butterfly valve body castings, and more particularly to scribing inspection tooling for butterfly valve body castings. Background Technology

[0002] The butterfly valve body casting is a ring-shaped casting, which is prone to deformation during the casting process. Therefore, frequent dimensional inspections are required, including finding the horizontal and vertical center lines. However, due to the structure of the butterfly valve body, only the horizontal center line can be drawn; the casting cannot stand upright to draw the vertical center line. A crane must be used to lift the casting, and a vertical support plate must be used to help it stand upright before marking. This marking method often results in significant errors because the crane is not stable and the casting cannot be perfectly perpendicular to the platform. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a scribing inspection tool for butterfly valve body castings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fixture for scribing and inspecting butterfly valve body castings includes a base with a placement frame movably mounted on top of the base; it also includes a drive motor and transmission components for driving the placement frame to rotate on the base; a T-shaped groove is provided on the side of the placement frame, and a fastening component is movably disposed inside the groove. A pressing component is threaded onto one end of the fastening component extending to the side of the placement frame for pressing and fixing the butterfly valve body casting placed on the placement frame; a movable component is movably disposed inside the groove, and a support component is provided at one end of the movable component extending to the side of the placement frame for supporting the butterfly valve body casting placed on the placement frame. The movable component has a first cavity inside and a second cavity inside, with the interior of the second cavity communicating with the interior of the first cavity. An L-shaped limiting component is installed inside the first cavity via a spring. A horizontally positioned extension component is installed at one end of the limiting component extending into the second cavity, and a pressing component is installed at one end of the extension component extending to the side of the supporting component. The inner wall of the slide groove has spaced limiting grooves, and a limiting protrusion is provided at one end of the limiting component extending into the slide groove, with the position of the limiting protrusion corresponding to the position of the limiting groove. The component also includes a controller for controlling the drive motor.

[0006] Preferably, an arc-shaped bracket is installed on one side of the placement rack to support the side of the butterfly valve body casting when in a vertical position.

[0007] Preferably, the inner arc surface of the arc-shaped bracket has a groove, and a ball bearing is movably disposed inside the groove.

[0008] Preferably, the placement rack has a cross structure; the support components are located at the four ends of the placement rack.

[0009] Preferably, the pressing component is provided with an anti-slip component on the side near the butterfly valve body casting.

[0010] The beneficial effects of this invention are as follows:

[0011] During use, the butterfly valve body casting is placed on the placement rack. The position of the pressing component is adjusted by screwing the fastening components to press and fix the butterfly valve body casting. When placing the butterfly valve body casting, the support component supports the sides of the casting. The placement rack can be adjusted to horizontal or vertical positions via a drive motor and transmission components, facilitating scribing and inspection of the butterfly valve body casting in both vertical and horizontal positions, ensuring more accurate scribing measurements. Furthermore, the position of the support component within the groove can be moved according to the dimensions of the butterfly valve body casting. This device is suitable for butterfly valve body castings of different sizes and has a wide range of applications. When moving the support component, pressing the pressing component pushes the limiting component into the first cavity through the extension component, causing the limiting protrusion at one end of the limiting component to move away from the inside of the limiting groove. After the support component has moved, the limiting component returns to its original position under the elastic action of the mounting spring, and the limiting protrusion at one end of the limiting component inserts into the limiting groove, thus limiting the position of the support component and preventing the support component from sliding in the groove due to gravity when in the vertical working position.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Reference Figures 1 to 4 A scribing inspection fixture for butterfly valve body castings includes a base 1, on the top of which a placement frame 6 is movably mounted; it also includes a drive motor 2 and a transmission component 4 for driving the placement frame 6 to rotate on the base 1; a T-shaped slide groove 10 is provided on the side of the placement frame 6, and a mounting fastening component 8 is movably disposed inside the slide groove 10. A pressing component 7 is threaded onto one end of the mounting fastening component 8 extending to the side of the placement frame 6 for pressing and fixing the butterfly valve body casting body 11 placed on the placement frame 6; a movable component 13 is movably disposed inside the slide groove 10, and a support component 5 is provided at one end of the movable component 13 extending to the side of the placement frame 6 for supporting the butterfly valve body casting body 11 placed on the placement frame 6; the movable component 13... The moving part 13 has a first cavity 14 inside, and a second cavity 15 is provided inside the second cavity 15, which communicates with the interior of the first cavity 14. An L-shaped limiting part 18 is installed inside the first cavity 14 by a spring 20. A horizontally arranged extension part 16 is installed at one end of the limiting part 18 that extends into the second cavity 15, and a pressing part 17 is provided at one end of the extension part 16 that extends into the side of the support part 5. The inner wall of the slide groove 10 has spaced limiting grooves 19. A limiting protrusion is provided at one end of the limiting part 18 that extends into the slide groove 10, and the position of the limiting protrusion corresponds to the position of the limiting groove 19. The system also includes a controller 3 for controlling the drive motor 2.

[0019] In use, the butterfly valve body casting 11 is placed on the placement rack 6. The position of the pressing component 7 is adjusted by screwing the fastening component 8 to press and fix the butterfly valve body casting 11. When placing the butterfly valve body casting 11, the support component 5 supports the side of the butterfly valve body casting 11. The placement rack 6 can be adjusted to be horizontal or vertical by the drive motor 2 and the transmission component 4, which facilitates the scribing and inspection of the butterfly valve body casting 11 in vertical and horizontal positions. The position of the support component 5 in the slide groove 10 can be moved according to the size of the butterfly valve body casting 11, making it suitable for different sizes. The butterfly valve body casting 11 has a wide range of applications. When the support component 5 is moved, the pressing component 17 is pressed, thereby pushing the limiting component 18 into the first cavity 14 through the extension component 16. This causes the limiting protrusion at one end of the limiting component 18 to move away from the inside of the limiting groove 19. After the support component 5 has moved, the limiting component 18 is reset under the elastic action of the mounting spring 20. The limiting protrusion at one end of the limiting component 18 is inserted into the limiting groove 19 to limit the position of the support component 5, thus preventing the support component 5 from sliding in the slide groove 10 due to gravity when in the vertical working position.

[0023] In a preferred embodiment of the present invention, the placement rack 6 has a cross structure; the support components 5 are located at the four ends of the placement rack 6.

[0024] In a preferred embodiment of the present invention, the pressing component 7 is provided with an anti-slip component on the side near the butterfly valve body casting 11.

[0025] In use, the butterfly valve body casting 11 is placed on the placement rack 6. The position of the pressing component 7 is adjusted by screwing the fastening component 8 to press and fix the butterfly valve body casting 11. When placing the butterfly valve body casting 11, the support component 5 supports the side of the butterfly valve body casting 11. The placement rack 6 can be adjusted to be horizontal or vertical by the drive motor 2 and the transmission component 4, which facilitates the scribing and inspection of the butterfly valve body casting 11 in vertical and horizontal positions. The position of the support component 5 in the slide groove 10 can be moved according to the size of the butterfly valve body casting 11, making it suitable for butterfly valve body castings of different sizes and with a wide range of applications. When pressing the pressing component 17, the extension component 16 pushes the limiting component 18 to its position in the first cavity 14, causing the limiting protrusion at one end of the limiting component 18 to move away from the inside of the limiting groove 19. After the supporting component 5 has moved, the limiting component 18 is reset under the elastic action of the mounting spring 20, and the limiting protrusion at one end of the limiting component 18 is inserted into the limiting groove 19 to limit the position of the supporting component 5, so as to prevent the supporting component 5 from sliding displacement in the slide groove 10 due to gravity when in the vertical working position. When adjusting the angle of the butterfly valve body casting 11 in the vertical working position, the ball 9 reduces the friction between the butterfly valve body casting 11 and the arc-shaped bracket 12.
