[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0029] See Figures 1-7As shown, a housing assembly mechanism for a bidirectional shut-off valve has the core function of achieving precise assembly of the bidirectional shut-off valve housing. It includes a base plate 1, a vertical plate 2 on the base plate 1, and a first carrier plate 3 above the vertical plate 2, which is an important component for placing one of the housings (first housing) of the bidirectional shut-off valve.

[0030] The first carrier plate 3 can move back and forth under the drive of the first moving assembly. Specifically, the first moving assembly includes a long rod cylinder 4 mounted on the vertical plate 2, and the piston end of the long rod cylinder 4 is fixedly connected to the first carrier plate 3 via a connector 5. When the long rod cylinder 4 is working, the extension and retraction of the piston is transmitted to the first carrier plate 3 through the connector 5, thereby realizing the back and forth movement of the first carrier plate 3. To ensure the smoothness and straightness of the movement of the first carrier plate 3, a first linear slide rail 6 is provided on the vertical plate 2. The first carrier plate 3 slides against the first linear slide rail 6 via a slider, effectively reducing friction and shaking during the movement.

[0031] To precisely limit the movement range of the first baffle 7 and thus control the movement stroke of the first carrier plate 3, ensuring the positional accuracy of the bidirectional shut-off valve housing during assembly, a first baffle 7 is fixedly installed on the first carrier plate 3, and a set of limiters 8 is installed on the vertical plate 2. The limiters 8 are used to limit the movement range of the first baffle 7 to avoid affecting the assembly quality due to excessive or insufficient movement.

[0032] A first mounting base 9 is provided near the proximal end of the first carrier plate 3, which provides a precise position for placing the first housing 10. Figure 7 As shown, the first cavity 91 opened on the first mounting base 9 has a shape and size that matches the first housing 10, and can play a preliminary positioning role for the first housing 10.

[0033] To ensure the first housing 10 remains stable during assembly, a clamping assembly is provided on the first carrier plate 3. Figure 6 As shown, the clamping assembly includes a clamping cylinder 25, which is mounted on the first carrier plate 3. The piston end of the clamping cylinder 25 is connected to one end of the connecting plate 11, and the other end of the connecting plate 11 is fixedly connected to the clamping block 12. The lower end of the clamping block 12 has a third cavity that matches the outer contour of the first housing 10. When the clamping cylinder 25 is activated, the extension and retraction of the piston causes the connecting plate 11 to move. The third cavity at the lower end of the clamping block 12 matches the outer contour of the first housing 10, allowing it to fit tightly against the first housing 10 and firmly fix it within the first cavity 91, ensuring assembly accuracy.

[0034] A set of sensors 13 is provided on the outside of the first mounting base 9. These sensors 13 can be common types such as photoelectric sensors, or other types of sensors capable of similar detection functions can be used as equivalent replacements. The first mounting base 9 is specifically provided with a sensing channel 92 communicating with the first cavity 91, allowing light emitted by the sensors 13 to pass through this sensing channel 92 without obstruction. When the first housing 10 is placed inside the first cavity 91, it blocks the light emitted by the sensors 13. The sensors 13 receive the light change signal, thereby determining that the first housing 10 has been placed inside the first cavity 91, providing accurate detection information for subsequent assembly processes.

[0035] A second carrier plate 14 is disposed on the outer side of the first mounting base 9. To enable flexible operation of the second housing 16, the second carrier plate 14 has the functions of vertical lifting and forward and backward movement under the drive of the second moving component. The second moving component can be in the form of a combination of a lifting cylinder and a forward and backward movement cylinder. The lifting cylinder realizes vertical lifting, and the forward and backward movement cylinder realizes forward and backward movement.

[0036] A second mounting base 15 is provided above the second carrier plate 14. A second cavity 151 is opened on the second mounting base 15, the shape and size of which are adapted to the second housing 16 for placing the second housing 16. To ensure that the second housing 16 is accurately and stably positioned in the second cavity 151, a clamping assembly is provided on the second carrier plate 14 for precisely positioning the second housing 16 in the second cavity 151.

[0037] Specifically, the second moving component includes a vertical cylinder 17 and a second linear slide rail 18 disposed on the vertical plate 2. The second linear slide rail 18 is connected to the third carrier plate via a slider. The vertical cylinder 17 is connected to the third carrier plate via a connector. When the vertical cylinder 17 extends or retracts, it drives the third carrier plate to rise and fall vertically along the second linear slide rail 18.

[0038] A support plate 19 and a horizontal cylinder 20 are fixedly mounted on the third carrier plate. A third linear slide rail is horizontally distributed on the support plate 19 and is connected to the second carrier plate 14 via a slider. The piston end of the horizontal cylinder 20 is connected to the second carrier plate 14 via a connecting plate 21. When the horizontal cylinder 20 operates, it pushes the second carrier plate 14 to move back and forth along the third linear slide rail, thereby realizing the two-dimensional motion of the second carrier plate 14.

[0039] Combination Figure 5 As shown, the second mounting base 15 adopts a structure in which the main body block and the step block are integrally formed. This design ensures the strength and stability of the overall structure. The connection between the main body block and the step block is a vertical plane, which provides a regular reference surface for the installation and positioning of subsequent components.

[0040] The main body block is provided with a second cavity 151 for precisely placing the second housing 16. The main body blocks on both sides of the second cavity 151 are also provided with insertion channels 152, which are connected to the second cavity 151. These insertion channels 152 can be used to insert positioning components to further fix the position of the second housing 16.

[0041] The upper surface of the stepped block has a protrusion 153, and a horizontal channel 154 is formed on the upper surface of the stepped block on one side of the protrusion 153. A set of sensors 21 are installed on both sides of the stepped block. The sensors 21 can be common types such as photoelectric sensors, or other types of sensors that can achieve similar detection functions can be used instead. The light emitted by the sensors 21 passes through the end face of the horizontal channel 154. When the second housing 16 is installed in place, it will block the light, and the sensors 21 will receive a signal change, thereby accurately monitoring whether the second housing 16 is installed in place, providing reliable quality inspection assurance for the entire assembly process.

[0042] Furthermore, the clamping assembly uses a double-headed clamping cylinder 22 as its power source. A clamping arm 23 is mounted on the double-headed clamping cylinder 22. The clamping arm 23 can be designed in different shapes and sizes to adapt to different installation environments. A clamping block 24 is provided on the clamping arm 23, and the shape of the clamping block 24 is adapted to the insertion channel 152. When the double-headed clamping cylinder 22 is activated, it drives the clamping arm 23 to move, causing the clamping block 24 to insert into the insertion channel 152, thereby firmly clamping and positioning the second housing 16 placed in the second cavity 151.

[0043] During assembly, one end of the first housing 10 is exposed outside the first mounting base 9, and a welding surface is carefully provided on this exposed part. This welding surface is the location for subsequent laser welding. During assembly, one end of the second housing 16 is precisely fitted onto the first housing 10, completely covering the welding surface. This structural design provides a stable connection basis for subsequent welding operations.

[0044] To improve the laser welding effect, a light-absorbing material coating is applied to the welding surface. This coating efficiently absorbs laser energy, causing the welding surface to heat up and melt rapidly, thus enhancing the weld's strength. This coating can be made from common laser-absorbing paints and applied evenly to the welding surface through processes such as spraying.

[0045] Accordingly, the second housing 16 is made of a light-transmitting material, such as transparent plastic or glass fiber reinforced plastic with high light transmittance, or other materials that meet the requirements for light transmittance and strength. This design allows the laser to penetrate the second housing 16 smoothly and act on the welding surface, achieving reliable welding and fixing of the first housing 10 and the second housing 16, and ensuring the quality and performance of the bidirectional shut-off valve housing assembly.

[0046] This invention utilizes a first cavity in the first mounting base, combined with a clamping assembly, to securely and precisely fix the first housing. The second cavity in the second mounting base, in conjunction with a double-headed clamping cylinder and clamping block, firmly clamps and positions the second housing. Furthermore, a second moving assembly allows for flexible adjustment of the second carrier plate, ensuring precise alignment of the second housing. Simultaneously, sensors located at the first mounting base and the stepped block monitor whether the first and second housings are properly positioned, providing timely feedback to prevent assembly errors. The light-absorbing material coating on the welding surface of the first housing, combined with the light-transmitting material on the second housing, facilitates laser welding penetration, enabling rapid melting of the welding surface, enhancing weld strength, and improving weld quality.
