[0039] This application relates to a multi-functional test tooling, which will be explained in detail below through specific implementation manners.

[0040] A multi-functional test tooling includes:

[0041] A vibration base 1, which is arranged on a vibration machine table;

[0042] The vibration base 1 has 400 M3 screw holes for fixing the heat dissipation bottom plate 21 of the heat dissipation tooling 2 and the spacer block 28 with M2×20 cross recessed pan head screws;

[0043] The heat dissipation tooling 2, which is arranged on the vibration base 1 and has multiple groups;

[0044] It is characterized in that each group of heat dissipation tooling 2 includes:

[0045] A spacer block 28, which is arranged on the vibration base 1;

[0046] A test component 3, which is arranged above the spacer block 28;

[0047] A heat dissipation bottom plate 21, which is arranged on the test component 3, and multiple T-shaped grooves 212 and thermal pad placement grooves 211 are opened on the heat dissipation bottom plate 21;

[0048] There are 3 M2 mounting holes 11 on the heat dissipation bottom plate 21, and the test component 3 can be fixed on the heat dissipation bottom plate 21 with M2×5 pan head screws.

[0049] Heat dissipation fins 22, which are adapted to the T-shaped grooves 212 and are arranged in the T-shaped grooves 212.

[0050] The heat dissipation fin 22 is made in the form of two thin aluminum plates spliced together. They are two thin aluminum plates formed by wire cutting. The connection between the two aluminum plates is fixed by soldering to form a T shape.

[0051] In the utility model, a heat dissipation tooling 2 that contacts the test component 3 is designed on the vibration bottom plate. Compared with the traditional vibration tooling, this application can prevent the overheating phenomenon of the high heat consumption test component 3 during the vibration test. At the same time, this application has low manufacturing cost, is easy to install, and is convenient for processing.

[0052] Compared with the conventional vibration tooling, this tooling is more suitable for vibration testing of high-power components;

[0053] Compared with the conventional radiator, the fins of this tooling are more convenient to manufacture and cheaper in cost.

[0054] Compared with the conventional test tooling, this tooling has the functions of vibration screening, vibration testing, and heat dissipation at the same time.

[0055] In a further embodiment, mounting holes 11 are formed on the vibration base 1 for assembling with a vibration machine table.

[0056] In a further embodiment, a first limiting block 23 and a second limiting block 26 are respectively arranged on both sides of the heat dissipation bottom plate 21. During connection, they are fixed by M1.6 pan head screws.

[0057] In a further embodiment, a threaded adapter 24 connected to the test component 3 is arranged on the side of the first limiting block 23, and a threaded hole adapted to the threaded adapter 24 is formed on the side of the first limiting block 23.

[0058] In a further embodiment, a flange connector 27 connected to the test component 3 is arranged on the side of the second limiting block 26. A through hole adapted to the flange connector 27 is formed on the side of the second limiting block 26, and the flange connector 27 is locked into the second limiting block 26 by an M2 pan head screw.

[0059] In a further embodiment, a pressing block 25 that abuts against the test component 3 is further arranged on the heat dissipation bottom plate 21.

[0060] By designing the pressure applied to the heat dissipation bottom plate 21 on the pressing block 25, it is prevented that the pan head screw for fixing the test component 3 on the heat dissipation bottom plate 21 presses the test component 3 to warp, affecting the contact between the heat dissipation surface of the test component 3 and the heat dissipation bottom plate 21.

[0061] Principle of operation description:

[0062] 1. Vibration screening of components (no testing during screening):

[0063] Fix the test component 3 on the heat dissipation bottom plate 21 with M2 pan head screws and the pressing block 25;

[0064] Lock the heat dissipation base plate 21 and the spacer block 28 on the vibration base 1 with M3×20 pan head screws;

[0065] As Figure 7 shown, install the vibration base 1 onto the vibration machine table through the mounting holes 11, and then the vibration screening work can be started. This screening process does not involve power-on testing, and the test component 3 does not work.

[0066] II. Power-on vibration test for the components:

[0067] Fix the test component 3 on the heat dissipation base plate 21 with M2 pan head screws and the pressure block 25;

[0068] Fix the first limit block 23 and the second limit block 26 on the heat dissipation base plate 21 with M1.6 pan head screws;

[0069] Screw the threaded adapter 24 into the first limit block 23 through the threaded hole and connect it to the test component 3;

[0070] Lock the flange connector 27 into the second limit block 26 with M2 pan head screws and connect it to the test component 3;

[0071] Snap the heat dissipation fin 22 into the heat dissipation base plate 21 through the T-shaped groove 212 of the heat dissipation base plate 21;

[0072] Lock the heat dissipation base plate 21 and the spacer block 28 on the vibration base 1 with M3×20 pan head screws;

[0073] Due to the need for electrical signal transmission with the outside world during the test, the threaded adapter 24 and the flange connector 27 need to be externally connected with cables.

[0074] To enhance heat dissipation, a fan can be used to blow air at the ventilation openings of the heat dissipation fins 22, as Figure 8 shown.

[0075] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the protection scope of the present invention.
