[0039] EMBODIMENTS

[0040] Reference is made to Figures 1-4 ​In the embodiment, a bonding force detection device is provided for detecting the bonding force between a first object 100 and a second object 200. For the convenience of description, the bonding force detection device is referred to as a detection device hereinafter.

[0041] The detection device comprises a tool body 300, which is internally provided with a mounting hole 310 and a fluid passage 320 for fluid inflow. The mounting hole 310 is in communication with the fluid passage 320. The tool body 300 can be made of high-temperature-resistant and corrosion-resistant materials, such as alloy materials, high-molecular materials, etc.

[0042] The first object 100 is mounted in the mounting hole 310, and the second object 200 is at least partially arranged in the space between the inner wall of the mounting hole 310 and the first object 100.

[0043] The second object 200 is fixedly connected with the tool body 300. A sealing structure 400 is arranged between the second object 200 and the tool body 300, which is used to seal the gap between the second object 200 and the tool body 300, so that the fluid cannot be discharged from the gap between the second object 200 and the tool body 300.

[0044] In the embodiment, the second object 200 is at least partially arranged in the space between the inner wall of the mounting hole 310 and the first object 100, which makes the shape of the bonding surface between the first object 100 and the second object 200 more complex and more consistent with the actual application scenario.

[0045] When detecting, the fluid (gas or liquid) is delivered into the fluid passage 320. With the flow of the fluid, the fluid flows into the mounting hole 310. Due to the presence of the sealing structure 400, the only possible leakage path of the fluid is only in the bonding place between the first object 100 and the second object 200, so that the bonding force between the first object 100 and the second object 200 can be detected. By detecting the leakage of the fluid and according to the pressure of the liquid inside the mounting hole 310 or the fluid passage 320, the quantitative detection of the bonding force is realized, and accurate and quantitative data are obtained.

[0046] The test personnel can deliver liquid with different temperatures and different pressures into the fluid passage 320, so as to comprehensively test the related properties of the material, such as shrinkage, linear expansion coefficient, corrosion resistance, etc., not limited to static stress test.

[0047] In the embodiment, the first material is a rigid material, such as metal, glass, ceramic, etc., and the second material is a polymer.

[0048] As Figures 5-7As shown, the first object 100 includes an inserting portion 110 , and the second object 200 includes a first component portion 210 . Both the inserting portion 110 and the first component portion 210 are located in the mounting hole 310 .

[0049] The first component 210 is located in the gap between the inner wall of the mounting hole 310 and the first object 100 , wherein the protruding portion 110 is at least partially wrapped by the first component 210 .

[0050] Furthermore, the second object 200 further includes a second component 220, and the second component 220 is located outside the mounting hole 310. The first component 210 and the second component 220 are seamlessly connected, and the second component 220 is arranged along the circumference of the end of the first component 210.

[0051] The first object 100 further includes an exposed portion 120 , which is located outside the mounting hole 310 .

[0052] like Figure 8 As shown, the exposed portion 120 is partially wrapped by the second component 220, and the top of the exposed portion 120 protrudes from the upper end surface 2211 of the second component 220. Figure 8 In the figure, for easy distinction, the inserted portion 110 and exposed portion 120 of the first object 100 are marked with different cross-section lines, while the first component 210 and second component 220 of the second object 200 are marked with different cross-section lines. In actual manufacturing, the inserted portion 110 and exposed portion 120 can be a one-piece structure, and the first component 210 and second component 220 can be a one-piece structure.

[0053] Both the exposed portion 120 and the inserted portion 110 can be cylindrical, with the cross-sectional area of ​​the exposed portion 120 being greater than that of the inserted portion 110. The exposed portion 120 and the inserted portion 110 are coaxial. The exposed portion 120 and the inserted portion 110 are not limited to cylindrical shapes and can also be configured in other shapes as needed, such as prisms, spheres, etc. Because the inserted portion 110 is at least partially enclosed by the first component 210, the shape of the interface between the first object 100 and the second object 200 will also vary depending on the shape of the inserted portion 110.

[0054] In this embodiment, the first component 210 and the second component 220 are an integrated structure, and the second object 200 is fixedly connected to the tool body 300 via the second component 220 .

[0055] The first component 210 and the second component 220 can be integrally formed by injection molding or other processes. The second object 200 can be directly formed on the first object 100 by injection molding.

[0056] like Figure 6and Figure 7 As shown, the second component 220 includes a first connecting lug 222 and a second connecting lug 223 which are symmetrically arranged, and the first connecting lug 222 and the second connecting lug 223 are fixedly connected with the tool body 300.

[0057] Since the first connecting lug 222 and the second connecting lug 223 are symmetrically arranged and are fixedly connected with the tool body 300, the reliability and stability of the connection between the second object 200 and the tool body 300 can be ensured, and the situation that the connection between the second object 200 and the tool body 300 is loose due to excessive pressure of the fluid can be avoided.

[0058] In the embodiment, the second object 200 and the tool body 300 can be fixedly connected by means of bolt connection. In addition, the fixed connection can also be achieved by means of clamping, nailing, bonding and the like.

[0059] Specifically, the first connecting lug 222 and the second connecting lug 223 are both provided with a penetrating hole 224, and the tool body 300 is provided with a threaded hole 301, wherein the penetrating hole 224 corresponds to the threaded hole 301. In the embodiment, the penetrating hole 224 corresponds to the threaded hole 301 one by one.

[0060] In order to realize screw connection, the detection device further includes a connecting bolt 500, the connecting bolt 500 penetrates the penetrating hole 224 and is threadedly connected with the threaded hole 301. The connecting bolt 500 can be sleeved with a gasket 510, and the gasket 510 is pressed on the upper end surface 2211 of the second component 220 by the head of the connecting bolt 500. The gasket 510 has the functions of increasing the contact area, reducing the pressure, preventing loosening and the like. The upper end surface 2211 of the second component 220 includes the upper end surface 2211 of the first connecting lug 222 and the upper end surface 2211 of the second connecting lug 223.

[0061] Since the sealing structure 400 is arranged between the second object 200 and the tool body 300, the only possible leakage path of the fluid can only exist at the joint between the first object 100 and the second object 200, based on which the detection of the joint force of the first object 100 and the second object 200 is realized.

[0062] In the embodiment, the sealing structure 400 is arranged outside the mounting hole 310, and the sealing structure 400 is arranged between the lower end surface 2212 of the second component 220 and the mounting end surface 302 of the tool body 300. The sealing structure 400 is arranged around the mounting hole 310, and the lower end surface 2212 of the second component 220 faces the mounting end surface 302 of the tool body 300.

[0063] As shown in FIG. 4, the sealing structure 400 is arranged between the lower end surface 2212 of the second component 220 and the mounting end surface 302 of the tool body 300. Figure 7As shown, the lower end surface 2212 of the second component body is provided with a first embedding groove 225; as Figure 3 As shown, the mounting end surface 302 of the tool body 300 is provided with a second embedding groove 303. The sealing structure 400 is partially embedded in the first embedding groove 225 and partially embedded in the second embedding groove 303. Through the cooperation between the sealing structure 400 and the first embedding groove 225 and the second embedding groove 303, not only the positioning of the sealing structure 400 is achieved, but also the sealing effect is improved. The sealing structure 400 can adopt a sealing ring.

[0064] In other embodiments, the sealing structure 400 is arranged inside the mounting hole 310, and the sealing structure 400 is arranged between the outer wall of the first component 210 and the inner wall of the mounting hole 310. The sealing structure 400 surrounds the first component 210.

[0065] As shown, Figure 4 As shown, the mounting hole 310 includes a first hole end 311 and a second hole end 312, and the fluid passage 320 includes a first end 321 and a second end 322. The first hole end 311 is formed with a first opening 304 on the surface of the tool body 300, and the first end 321 is formed with a second opening 305 on the surface of the tool body 300. The second hole end 312 and the second end 322 are both located inside the tool body 300, and the second hole end 312 and the second end 322 are in communication. In this embodiment, the sealing structure 400 surrounds the first opening 304.

[0066] The second opening 305 is detachably mounted with a connector 600, wherein the connector 600 is used to connect with a pipeline conveying fluid. The connector 600 and the second opening 305 can be detachably connected by means of threaded connection or the like.

[0067] In this embodiment, the detection device further includes a liquid explosion device or / and a gas tightness detection device. The liquid explosion device is used to deliver high-pressure liquid into the fluid passage 320; the gas tightness detection device is used to detect the sealing property between the first object 100 and the second object 200. Through the explosion experiment and the gas tightness detection, accurate quantitative evaluation indexes can be obtained, so that the differences between different polymers can be more accurately compared. The explosion experiment is a destructive way to detect the strength of the combination of the first object 100 and the second object 200.

[0068] The liquid explosion device can refer to the existing technology.

[0069] The air tightness detection device can include an air pressure sensor, etc. The air pressure sensor can be prearranged in the fluid passage 320. When air tightness detection is performed, after a certain amount of gas is injected into the fluid passage, the second opening 305 is immediately closed, and the current pressure value is obtained by the air pressure sensor, which is set as the first pressure value; after a period of time, the current pressure value is obtained by the air pressure sensor, which is set as the second pressure value; comparison of the first pressure value and the second pressure value can realize judgment of air tightness.
