[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: An axial positioning mechanism for the output shaft of a pneumatic solenoid valve drive device, such as... Figures 1-4As shown, the device includes a cylinder body 1, an output shaft 2, and a valve body 3. The output shaft 2 is the output shaft of the cylinder body 1. The valve body 3 is installed on the outside of the cylinder body 1, and the cylinder body 1 is connected to the cylinder body 1 through an external pipe. An installation frame 4 is installed on the outer surface of one side of the output end of the cylinder body 1. Insertion slots 5 are opened on both sides of the upper end of the installation frame 4. Insertion connectors 6 are inserted into the two insertion slots 5 at the same time. Connecting plates 7 are connected to the outside of the two insertion connectors 6 at the same time. At least two side positioning blocks 8 are installed on the outer surface of the connecting plate 7. A central support block 9 is slidably arranged between the two side positioning blocks 8. The central support block 9 has an arc-shaped concave surface in the middle, and the specifications of the arc-shaped concave surface of the central support block 9 are consistent with the specifications of the outer surface of the output shaft 2. The outer surface of the output shaft 2 is in contact with the inner surface of the central support block 9.

[0027] Based on the operation support of the valve body 3 on the cylinder body 1, the normal stability of the cylinder body 1 during use is ensured. And with the support of the middle support block 9, the axial movement angle of the output shaft 2 is ensured to be accurate during load-bearing and movement. Specifically, firstly, the plug 6 is inserted into the plug slots 5 on both sides. Based on the connection guide of the connecting plate 7, the side positioning blocks 8 on both sides are positioned synchronously. Then, the middle support block 9 is aligned from below, so that it gradually contacts the outer surface of the output shaft 2 under the limiting guide of the side positioning blocks 8 on both sides. Then, the plug 6 and the middle support block 9 are positioned respectively, so that the middle support block 9 is stable below the output shaft 2, providing support for it and ensuring the long-term stability of the axial angle of the output shaft 2 during use, preventing the axial angle deviation due to long-term use and excessive use intensity.

[0028] like Figures 1-4 As shown, the connector 6 is L-shaped, and the horizontal part of the connector 6 extends to the outside of the mounting frame 4. The upper half of the connector groove 5 extends through to the outside of the mounting frame 4. The connector 6 and the connecting plate 7 have a certain space on the adjacent side, and the thickness of the space is the same as the thickness of the inner wall of the connector groove 5.

[0029] With the positioning and insertion of the connector 6, the connecting plate 7 is used in the positioning state. With the support of the space between the connector 6 and the connecting plate 7, the connector 6 is inserted into the insertion slot 5, ensuring the accurate connection of the connecting plate 7. This allows the mounting frame 4, the insertion slot 5, and the side positioning block 8 to be in the same stable state, thus forming a unified movement, which facilitates subsequent adjustment and movement.

[0030] like Figures 1-4 As shown, an auxiliary groove 601 is provided on the upper surface of the connector 6, a fastening top plate 10 is installed above the connector 6, and an auxiliary block 1001 is installed on the lower surface of the fastening top plate 10. The auxiliary block 1001 is inserted into the auxiliary groove 601.

[0031] The lower surface of the connector 6 is beveled on the outer side. A side push bracket 11 is provided on the lower side of the connector 6. The side push bracket 11 is slidably inserted into the interior of the side push bracket 11. A fastening bolt is threaded on the side push bracket 11. The side push bracket 11 is threadedly connected to the outer side of the mounting frame 4 through the fastening bolt.

[0032] After the connector 6 is inserted into the connector slot 5, the auxiliary block 1001 is inserted into the auxiliary slot 601 by moving the fastening top plate 10 downward. Then, the bolts on the fastening top plate 10 are tightened to fasten the fastening top plate 10 to the mounting frame 4. Thus, the output shaft 2 above the device provides a limit for the connector 6, ensuring the stability of the connecting plate 7 during use. The horizontal position of the side pusher 11 is adjusted so that it can be limited and fixed from below the connector 6, thus ensuring the reliability of the safe position of the connector 6. Furthermore, by pushing the side pusher 11, based on the inclination of the connection surface between the side pusher 11 and the connector 6, the connector 6 can be pushed upward, so that the connecting plate 7 and the side positioning block 8 can have the effect of height adjustment at the same time. Thus, under the simultaneous action of the fastening top plate 10 and the side pusher 11, the connection state of the connector 6 and the connector slot 5 is ensured, ensuring the overall stability and reliability of the device during use.

[0033] Example 2: An axial positioning mechanism for the output shaft of a pneumatic solenoid valve drive device, such as... Figures 1-4 As shown, the central support block 9 has positioning slots 902 on both sides. There are several positioning slots 902. Guide slides 901 are provided on both sides of the positioning slots 902. The guide slides 901 are installed on the surfaces of the central support block 9 on both sides.

[0034] At least two guide grooves 801 are provided on the surface of the side positioning block 8 near the middle support block 9. The guide slide 901 is slidably disposed inside the guide groove 801. A positioning insert 802 is provided between the two guide grooves 801. The positioning insert 802 slides through the opposite sides of the side positioning block 8 and is inserted into the positioning slot 902.

[0035] After the positions of the side positioning blocks 8 are fixed, firstly, the guide slides 901 on both sides of the central support block 9 are inserted into the guide slide grooves 801 on both sides. Then, the central support block 9 is continuously pushed to move it between the side positioning blocks 8. Based on the limitations of the specifications of the guide slide grooves 801 and guide slides 901, and the pre-set sliding distance, the accuracy of the moving position of the central support block 9 is ensured. Then, with the simultaneous insertion of multiple positioning plates 802 on both sides into the side positioning blocks 8 and the positioning slots 902, the central support block 9 is positioned between the side positioning blocks 8, thereby ensuring the stability and accuracy of the central support block 9 in moving and fixing its position. By setting the central support block 9 and the side positioning blocks 8 to be moved and installed separately, it is convenient to install them while allowing the support height of the central support block 9 to be adjusted individually, thereby improving the support strength.

[0036] like Figures 1-4 As shown, several positioning plates 802 are simultaneously connected to movable arc plates 12. Positioning bolts 13 are threaded through the movable arc plates 12. The positioning bolts 13 are threaded to the side positioning blocks 8, and the movable arc plates 12 are arc-shaped with the same specifications as the outer side of the side positioning blocks 8.

[0037] By pushing the movable arc plate 12, multiple positioning plates 802 can be moved synchronously. Then, with the fastening connection of multiple positioning bolts 13, the movable arc plate 12 is fixed to the outside of the side positioning block 8, forming a fixed and limiting support effect on the central support block 9, ensuring its stability during fixed use.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
