[0025] See also Figures 1 to 7 As shown, it is an embodiment of the present utility model. This embodiment discloses a pressure testing device 100, and the pressure testing device 100 includes a test platform 1 and a testing mechanism 2 installed on the test platform 1.
[0026] It should be noted that the test platform 1 in this embodiment is described as being used in conjunction with the test mechanism 2, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the test platform 1 can also be used alone (e.g., sold) or used in conjunction with other components.
[0027] like Figures 1 to 5 As shown, the platform 1 to be tested in this embodiment includes a support frame 11, an aluminum alloy bearing plate 12 installed on the support frame 11, and a connecting layer 13 disposed between the support frame 11 and the aluminum alloy bearing plate 12, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the platform 1 to be tested may also omit the connecting layer 13 according to actual needs.
[0028] Specifically, the support frame 11 includes four table legs 111, three support bars 112 connected to the four table legs 111, and four bases 113 respectively arranged at the bottom ends of the four table legs 111. The two ends of each support bar 112 are welded to two of the table legs 111, and the three support bars 112 surround the four table legs 111 to form a U-shaped structure, that is, an opening 114 is formed on one side of the support frame 11. The connection layer 13 may be made of a 5T polished steel plate, but the present invention is not limited thereto.
[0029] In this embodiment, the four table legs 111 and the three support bars 112 of the support frame 11 are preferably made of 304 stainless steel square tubes, and the four base feet 113 are preferably made of shockproof adjustable foot pads, but the present invention is not limited thereto.
[0030] The aluminum alloy bearing plate 12 is disposed on the connection layer 13, and the aluminum alloy bearing plate 12 is provided with a plurality of screw holes (not shown in the figure). Furthermore, the connection layer 13 is provided with a plurality of connection holes (not shown in the figure), and the plurality of connection holes of the connection layer 13 are connected with the plurality of screw holes of the aluminum alloy bearing plate 12. Therefore, the aluminum alloy bearing plate 12 can be installed and fixed on the connection layer 13 and the support frame 11 through the screw holes and the connection holes. The number of the plurality of screw holes and the plurality of connection holes can be adjusted according to actual needs, and the utility model does not limit them.
[0031] It is worth mentioning that the aluminum alloy carrier plate 12 also includes a polished outer surface. In detail, the outer surface of the aluminum alloy carrier plate 12 is subjected to a hard anodic treatment, and the aluminum alloy carrier plate 12 is placed in a low-temperature electrolyte through the hard anodic treatment, and a metal film is generated on the outer surface of the aluminum alloy carrier plate 12 by passing an electric current, and the metal film has high hardness and wear-resistant mechanical properties. Accordingly, the mechanical properties and durability of the platform 1 to be tested can be further improved by the metal film on the aluminum alloy carrier plate 12, and the polished outer surface of the aluminum alloy carrier plate 12 of the platform 1 to be tested can ensure that the aluminum alloy carrier plate 12 is smooth and prevent the aluminum alloy carrier plate 12 from being scratched.
[0032] like Figures 2 to 5 As shown, a groove 121 is concavely disposed at the substantially middle position of the aluminum alloy bearing plate 12. The groove 121 is substantially in the shape of a rectangular parallelepiped, and the groove 121 further comprises a groove length L1, a groove width W1, and a groove depth G. The groove length L1 is greater than the groove width W1, and the groove length L1 is defined along an opening direction D1 of the opening 114. In other words, the groove 121 is disposed in the aluminum alloy bearing plate 12 along the opening direction D1, and the groove length L1 of the groove 121 is parallel to the opening direction D1.
[0033] In addition, if Figure 4 As shown, the aluminum alloy bearing plate 12 further includes a bearing plate thickness H, and the bearing plate thickness H is greater than the groove depth G. That is, the groove 121 is recessed in the aluminum alloy bearing plate 12 , and the groove 121 is spaced apart from the connecting layer 13 by the aluminum alloy bearing plate 12 .
[0034] In more detail, Figure 5 and Figure 6 As shown, the aluminum alloy carrier plate 12 and the groove 121 have an area ratio range, which is preferably between 1:8 and 1:12, and the aluminum alloy carrier plate 12 is used to set a test object X, and the groove 121 can be used to accommodate a metal block M of the test object X. In this embodiment, a length L2 and a width W2 of the aluminum alloy carrier plate 12 are preferably between 700 mm and 900 mm, respectively, and the depth of the groove 121 is preferably between 5 mm and 10 mm. Accordingly, by lengthening the length L2 and the width W2 of the aluminum alloy carrier plate 12 to at least 700 mm, the aluminum alloy carrier plate 12 can be applied to more different sizes of the test objects X (such as PCB boards).
[0035] like Figure 1 , Figure 3and Figure 4 As shown, the test mechanism 2 includes a fixing frame 21 and a force gauge 22 mounted on the fixing frame 21. The test mechanism 2 is mounted on the test platform 1 through the fixing frame 21, and the force gauge 22 is located directly above the groove 121. In this embodiment, the force gauge 22 is preferably a thrust gauge or a pressure gauge, and the test range of the force gauge 22 is preferably between 0 and 100N, but the present invention is not limited thereto.
[0036] In detail, the fixing frame 21 includes a fixing beam 211, a fixing column 212 connected to one end of the fixing beam 211, a fixing block 213 connected to the other end of the fixing beam 211, a slide rail 214 installed on the fixing block 213, and a turntable 215 installed on the fixing block 213.
[0037] Specifically, the two ends of the fixed beam 211 are respectively connected to one end of the fixed column 212 and one side of the fixed block 213, the other end of the fixed column 212 is fixed to the aluminum alloy bearing plate 12 of the test platform 1, and the fixed column 212 is disposed adjacent to one side of the groove 121. In other words, when one end of the fixed beam 211 is connected to one end of the fixed column 212, the fixed beam 211 and the fixed column 212 generally form an L-shaped structure.
[0038] In addition, one side of the fixing block 213 is connected to the fixing beam 211, and the other side of the fixing block 213 not connected to the fixing beam 211 is installed with the slide rail 214 and the turntable 215, and the force gauge 22 is disposed on the slide rail 214. The turntable 215 can be used to adjust the position of the force gauge 22 on the slide rail 214.
[0039] Among them, the fixing column 212, the fixing beam 211, and the fixing block 213 are arranged in sequence along the opening direction D1 toward the opening 114; that is, the side of the fixing frame 21 on which the force gauge 22 is installed is arranged facing the opening 114 of the supporting frame 11, and the position of the force gauge 22 is located above the groove 121.
[0040] like Figure 6 and Figure 7 As shown, the force gauge 22 can move along an operation direction D2 on the fixed block 213 through the operation of the slide rail 214 and the turntable 215. That is, when the user operates the turntable 215, the force gauge 22 can move up and down along the slide rail 214.
[0041] In more detail, when the object to be tested X is placed on the test platform 1, the user can operate the turntable 215 to move the force gauge 22 downward, and a test end 221 of the force gauge 22 can be pressed down onto the metal block M of the object to be tested X, and the test end 221 of the force gauge 22 can apply pressure to the metal block M. At this time, the force gauge 22 will display the pressure value applied by the test end 221 of the force gauge 22 to the metal block M of the object to be tested X.
