[0045] Embodiment 1

[0046] like Figure 1-Figure 4As shown, the process device for gluing the sealing strip 10 of the helicopter fire bucket valve plate 9 includes a horizontal quick clamp 3 and a vertical quick clamp 7;

[0047] The horizontal quick clamp 3 is fixed on the mounting base plate 1, and the vertical quick clamp 7 is also fixed to the mounting base plate 1;

[0048] During bonding, the sealing strip 10 coated with adhesive needs to be installed on the valve plate 9;

[0049] The horizontal quick clamp 3 is provided with a horizontal head 3.1, which is used for horizontally extruding the valve plate 9 and the sealing strip 10; the vertical quick clamp 7 is provided with a vertical head 7.1, which is used for vertically extruding the valve plate 9 and the sealing strip 10.

[0050] The present invention is provided with a horizontal quick clamp 3 and a vertical quick clamp 7, and the valve plate 9 and the sealing strip 10 can be firmly clamped by the horizontal head 3.1 and the vertical head 7.1, and the valve plate 9 with the sealing strip 10 can be taken out after the adhesive is completely cured. This device can ensure the tight combination of the sealing strip 10 and the valve plate 9, and the bonding quality and assembly efficiency can be greatly improved.

Furthermore, the vertical quick clamp 7, the cushion block 6 and the mounting base plate 1 are fixed together by bolts. Since the vertical quick clamp 7 applies pressure from top to bottom, the height of the vertical quick clamp 7 can be guaranteed after being raised by the cushion block 6. In addition, the reason for such arrangement is to avoid the vertical quick clamp 7 from being too large in size, and part of the height is achieved by the cushion block 6, which can reduce the volume of the vertical quick clamp 7 and reduce the weight of the vertical quick clamp 7.

That is, an external thread is provided on the positioner 8, and a corresponding internal thread is provided on the mounting base plate 1, and the positioner 8 is threadedly connected to the mounting base plate 1. The positioner 8 is used to prevent the valve plate 9 or the sealing strip 10 from deviating when pressure is applied. When the positioner 8 is cylindrical, the positioning hole is a circular hole, and the diameter of the positioning hole is 1-2 mm larger than the outer diameter of the cylindrical positioner 8.

[0055] The present invention also includes a pressing ring 4, which is composed of at least two arc plates, and there is a certain gap between the arc plates; when the valve plate 9 and the sealing strip 10 are in place, the pressing ring 4 is placed on the outside of the valve plate 9 and the sealing strip 10, and the horizontal head 3.1 of the horizontal quick clamp 3 directly acts on the pressing ring 4. Due to the existence of the gap, the pressing ring 4 can be forced to shrink.

[0056] The present invention further comprises a pressing plate 5 . When the valve plate 9 and the sealing strip 10 are in place, the pressing plate 5 is placed on the valve plate 9 and the sealing strip 10 , and the vertical head 7 . 1 of the vertical quick clamp 7 acts directly on the pressing plate 5 .

[0059] The mounting base 3.4 is fixed on the mounting base plate 1, and the horizontal handle 3.2 is connected to the horizontal head 3.1 through the connecting plate 3.3;

[0060] The horizontal handle 3.2 is hinged to the connecting plate 3.3 and the mounting base 3.4 respectively, and the connecting plate 3.3 is hinged to the horizontal head 3.1; the extension amount (or clamping force) of the horizontal head 3.1 can be controlled by turning the horizontal handle 3.2.

[0061] like Figure 6 As shown, the vertical quick clamp 7 includes a vertical head 7.1, a first connecting member 7.2, a second connecting member 7.3, a vertical handle 7.4 (just a name to distinguish it from the "horizontal handle 3.2", not necessarily arranged vertically) and a fixed base 7.5;

[0062] The fixed base 7.5 is fixed to the mounting base plate 1, the first connecting member 7.2 is L-shaped, the first connecting member 7.2 is hinged to the vertical handle 7.4 and the fixed base 7.5 respectively, and the second connecting member 7.3 is hinged to the vertical handle 7.4 and the fixed base 7.5 respectively; the downward pressure (or clamping force) of the vertical head 7.1 can be controlled by turning the vertical handle 7.4.

[0063] like Figure 1-Figure 4 As shown, the valve plate 9 is circular, and a plurality of (for example, 8) horizontal heads 3.1 of the valve plate 9 are all facing the center of the valve plate 9. A plurality of vertical quick clamps 7 (for example, 8 vertical quick clamps 7) are arranged on the outer side of the valve plate 9 to clamp the sealing strip 10 and the valve plate 9 from top to bottom.
