[0029] Firstly, mounting frame 1 is placed stably on workbench, to ensure that the whole tool is in horizontal and stable state. Then, the pneumatic valve body to be assembled is placed on the top of placement plate 3, and placement plate 3 is designed at the inner cavity bottom of mounting frame 1, to provide a stable support platform for the valve body.

[0030] Next, the fixing plate is aligned with the positioning groove 7 at the bottom of the moving plate 2 and placed inside. The precise design of the positioning groove 7 ensures that the fixing plate can be accurately positioned, providing a basic guarantee for the subsequent assembly process. Several suction holes 6 are provided on both sides of the top of the inner cavity of the positioning groove 7. These suction holes 6 are connected to the suction structure on the top of the moving plate 2. When the fixing plate is placed in the positioning groove 7, the suction structure is activated, generating suction through the suction holes 6 to firmly adhere the fixing plate to the positioning groove 7, achieving temporary fixation of the fixing plate and preventing displacement of the fixing plate during subsequent operations.

[0031] Next, the moving plate 2 is driven downward along the top of the inner cavity of the mounting frame 1 by the vertical lifting assembly until the fixed plate slowly descends to the top of the valve body. The precise control of the vertical lifting assembly ensures the stability and accuracy of the fixed plate during its descent, providing favorable conditions for the docking of the fixed plate with the valve body.

[0032] Once the fixing plate is properly aligned with the valve body, the tightening machine can be easily accessed. Because this fixture design eliminates the limitations of traditional clamps on the tightening machine's operating space, the tightening machine can quickly position the bolts to be tightened and efficiently complete the tightening process, firmly fixing the fixing plate to the valve body while simultaneously pressing down the lower spring to ensure the normal operation and stability of the valve body.

[0033] Finally, after fixing the fixing plate, close the adsorption structure and release the adsorption positioning of the fixing plate. At this time, the processed valve body can be quickly and easily removed, ready for the assembly of the next valve body.

This achieves the effect of enhancing the overall structural stability and durability of the tooling, ensuring long-term reliability and accuracy.

[0037] Example 3

[0038] Please refer to Figures 1-5 As shown in the drawings, the special tool for pressing the fixing plate of the pneumatic valve body of the embodiment comprises an adsorption structure, a moving plate 2, a placing plate 3 and a mounting frame 1. The adsorption structure comprises two air suction cylinders 5, the two air suction cylinders 5 are respectively communicated with a plurality of adsorption holes 6 on the two sides, and one side of the two air suction cylinders 5 is communicated with an air suction device. Specifically, when the fixing plate is placed in the positioning groove 7, the air suction device is started to generate strong suction force through the air suction cylinder 5 and the adsorption hole 6, so that the fixing plate is adsorbed in the positioning groove 7. The effect of realizing fast and stable adsorption and positioning of the fixing plate is achieved, the displacement of the fixing plate in the subsequent operation is avoided, and the precision and efficiency of assembly are improved.

[0039] The vertical lifting assembly comprises two guide rods 10 and a push air cylinder 4. The push air cylinder 4 is connected with the top of the inner cavity of the mounting frame 1.

The two sides of the moving plate 2 are slidingly connected with the adjacent guide rods 10. Specifically, the push air cylinder 4 drives the moving plate 2 to move up and down along the guide rod 10. The guide rod 10 provides accurate guiding effect, ensuring the stability and accuracy of the moving plate 2. The effect of realizing accurate and stable lifting of the moving plate 2 is achieved, which provides favorable conditions for the butt joint of the fixing plate and the valve body, and improves the precision and efficiency of assembly.

[0040] The two sides of the moving plate 2 are fixedly connected with sliding rods 8 which are slidingly connected with the guide rods 10. The bottom of the sliding rod 8 is connected with a return spring 9 having one end connected with the top of the side plate 12. Specifically, after the push air cylinder 4 drives the moving plate 2 to descend to complete the pressing of the fixing plate, the air cylinder is closed, and the return spring 9 provides elastic force to make the moving plate 2 quickly reset, preparing for the next assembly. The effect of realizing quick resetting of the moving plate 2 is achieved, which improves the continuous operation capacity and assembly efficiency of the tool, reduces manual intervention, and reduces labor intensity.

[0041] The scheme has the following working process:

[0042] Firstly, the mounting frame 1 is stably placed on the workbench to ensure that the whole special tool for pressing the fixing plate of the pneumatic valve body is in a horizontal and stable state. Then, the pneumatic valve body to be assembled is placed in the placing groove 11 on the top of the placing plate 3. The design of the placing groove 11 provides a stable support platform for the valve body, and the anti-skid pad connected with the inner cavity bottom provides additional friction force, which ensures that the valve body will not slide or displace during assembly due to external force, enhances the stability of valve body placement, and ensures the smooth progress of the assembly process.

[0043] Subsequently, the fixed plate is aligned with the positioning groove 7 at the bottom of the moving plate 2 and placed therein. The precise design of the positioning groove 7 ensures that the fixed plate can be accurately positioned, providing a foundation guarantee for the subsequent assembly process. On both sides of the inner cavity top of the positioning groove 7, a plurality of adsorption holes 6 are provided, which communicate with the adsorption structure on the top of the moving plate 2. The adsorption structure includes two air suction cylinders 5, which respectively communicate with the plurality of adsorption holes 6 on both sides, and one side is communicated with the air suction equipment. When the fixed plate is placed in the positioning groove 7, the air suction equipment is started, and a strong suction force is generated through the air suction cylinder 5 and the adsorption hole 6 to adsorb the fixed plate firmly in the positioning groove 7, realizing the rapid and stable adsorption positioning of the fixed plate, avoiding the displacement of the fixed plate in the subsequent operation, and improving the accuracy and efficiency of the assembly.

[0044] Next, the moving plate 2 is driven by the vertical lifting assembly to move downward along the inner cavity top of the mounting frame 1. The vertical lifting assembly includes two guide rods 10 and a push cylinder 4, the push cylinder 4 is connected with the inner cavity top of the mounting frame 1, and the two guide rods 10 are respectively connected with the top of the two side plates 12 made of metal material, providing additional support and stability for the whole tool. The output end of the push cylinder 4 is connected with the top of the moving plate 2, and the two sides of the moving plate 2 are slidingly connected with the adjacent guide rods 10. At the same time, the two sides of the moving plate 2 are also fixedly connected with the sliding rods 8 which are slidingly connected with the guide rods 10, and the bottom of the sliding rods 8 is connected with the reset spring 9 which is connected with the top of the side plate 12. The push cylinder 4 drives the moving plate 2 to move up and down along the guide rods 10, and the guide rods 10 provide precise guidance to ensure the stability and accuracy of the moving plate 2, realizing the effect of accurate and stable lifting of the moving plate 2, and providing favorable conditions for the butt joint of the fixed plate and the valve body.

[0045] When the fixed plate and the valve body are butt jointed in place, the tightening machine can be conveniently accessed into the operation space. Because the design of the tool removes the limitation of the traditional clamp on the operation space of the tightening machine, the tightening machine can quickly position the bolts to be tightened and efficiently complete the tightening work of the bolts, firmly fixing the fixed plate on the valve body and compressing the spring below, ensuring the normal work and stability of the valve body.

[0046] Finally, after completing the fixation of the fixed plate, the air suction equipment is turned off to release the adsorption positioning of the fixed plate, and the push cylinder 4 is also turned off. The reset spring 9 provides elastic force to make the moving plate 2 quickly reset, preparing for the next assembly. This design realizes the effect of quick resetting of the moving plate 2, improves the continuous operation ability and assembly efficiency of the tool, and reduces the labor intensity.
