[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0030] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 A radiator testing fixture, comprising a base plate 11;
[0031] The upper end of the base plate 11 is symmetrically fixedly connected with limiting blocks 13 for pre-positioning the base 121 of the radiator 12; the upper ends of the opposing side walls of the limiting blocks 13 on both sides are provided with rounded corners to facilitate the positioning of the base 121; the upper end of the base plate 11 is connected with a clamping mechanism 1 2 for clamping and fixing the base 121; the upper end of the base plate 11 is connected with a clamping mechanism 2 3 for clamping and fixing the heat sink 122 of the radiator 12.
[0032] The clamping mechanism 3 includes a driving component 31 and a stabilizing clamping component 32. The driving component 31, which drives the stabilizing clamping component 32 to move up and down, is connected to the upper end of the base plate 11. The stabilizing clamping component 32, which clamps and fixes the heat sink 122, is connected to the lower end of the driving component 31 and is located on the upper side of the heat sink 12.
[0033] In this invention, the operator places the radiator 12 on the upper end of the base plate 11 and pre-positions the base 121 using the limiting block 13. At this time, the clamping mechanism 2 clamps and fixes the base 121, facilitating the operator to test the spacing of the heat sink 122. When the clamping mechanism 2 releases its clamping fixation on the base 121, the drive assembly 31 drives the stabilizing clamping assembly 32 to move downwards, stabilizing the clamping assembly 32 to stably clamp the heat sink 122, preventing it from shifting due to equipment vibration. The drive assembly 31 drives the stabilizing clamping assembly 32 to move the radiator 12 upwards, suspending the base 121. At this time, the heat dissipation performance of the radiator 12 is tested. By clamping and fixing the heat sink 122 and controlling the suspension of the base 121, heat from the base 121 is prevented from being dissipated through heat conduction via other workpieces, ensuring the accuracy of the test results for the heat dissipation performance of the heat sink 122.
[0034] The clamping mechanism 2 includes a cylinder 21, an L-shaped block 22, a guide rail 23, a clamping block 24, a connecting block 25, a first synchronous pulley 26, a second synchronous pulley 27, and a synchronous belt 28. Two clamping blocks 24 for fixing the base 121 are symmetrically arranged front and back on the upper end of the base plate 11. Guide rails 23 are symmetrically arranged on the lower side of each clamping block 24, and the lower end of each clamping block 24 is fixedly connected to the slider of the guide rail 23. The lower ends of the guide rails 23 are fixedly connected to the upper end of the base plate 11. A cylinder 21 is fixedly connected to the front side of the upper end of the base plate 11. The cylinder 21... An L-shaped block 22 is fixedly connected to the output end; the right end of the L-shaped block 22 is fixedly connected to the left end of the front clamping block 24; a connecting block 25 is fixedly connected to the lower end of each clamping block 24; a synchronous pulley 26 is rotatably connected to the front side of the lower end of the base plate 11; a synchronous pulley 27 is rotatably connected to the rear side of the lower end of the base plate 11; the synchronous pulley 26 and the synchronous pulley 27 are connected by a synchronous belt 28; the lower end of the front connecting block 25 passes through the base plate 11 and is fixedly connected to the left side of the synchronous belt 28, and the lower end of the rear connecting block 25 passes through the base plate 11 and is fixedly connected to the right side of the synchronous belt 28.
[0035] In this invention, the output end of cylinder 21 drives L-shaped block 22 to move front clamping block 24 backward along front guide rail 23. Front clamping block 24 drives synchronous belt 28 through front connecting block 25 to move rear connecting block 25 forward. At the same time, synchronous belt 28 drives synchronous pulley 26 and synchronous pulley 27 to rotate. Rear connecting block 25 drives rear clamping block 24 to move forward along rear guide rail 23, so that front and rear clamping blocks 24 move synchronously to base 121 and clamp and fix base 121, which makes it convenient for operators to detect the spacing of heat sink 122.
[0036] The drive assembly 31 includes a stand 311, a second cylinder 312, and a C-shaped frame 313. The stand 311 is fixedly connected to the upper end of the base plate 11; the second cylinder 312 is fixedly connected to the upper end of the stand 311; and the output end of the second cylinder 312 is fixedly connected to the C-shaped frame 313.
[0037] The stabilizing clamping assembly 32 includes a drive motor 321, a threaded rod 322, a slide rod 323, clamping plates 325, and a connecting plate 326. The drive motor 321 is fixedly connected to the right end of the C-shaped frame 313. The left and right ends of the threaded rod 322 are rotatably connected to the inner walls of the left and right sides of the C-shaped frame 313, respectively, with the threads of the left and right ends of the threaded rod 322 having opposite directions. The output end of the drive motor 321 is fixedly connected to the right end of the threaded rod 322. The left and right ends of the slide rod 323 are fixedly connected to the inner walls of the left and right sides of the C-shaped frame 313, respectively. Multiple clamping plates 325 are symmetrically arranged on the left and right sides of the threaded rod 322, with the leftmost clamping plate being the largest. The left end of the threaded rod 322 is threadedly connected to the left end of the threaded rod 322, and the rightmost clamping plate 325 is threadedly connected to the right end of the threaded rod 322. Two connecting plates 326 are symmetrically arranged on the lower side of the C-shaped frame 313. The upper ends of the left clamping plates 325 are fixedly connected to the upper ends of the left connecting plates 326, and the upper ends of the right clamping plates 325 are fixedly connected to the upper ends of the right connecting plates 326. The side walls of the inner clamping plates 325 are provided with two through slots to avoid the threaded rod 322 and the slide rod 323. The width of the clamping plate 325 is smaller than the distance between adjacent heat sinks 122. The clamping plates 325 are slidably connected to the slide rod 323.
[0038] In this invention, the output end of cylinder 312 drives C-frame 313 to move multiple clamping plates 325 downwards. These clamping plates 325 are inserted into the gaps between the heat sinks 122. The output end of drive motor 321, via threaded rod 322, drives the clamping plates 325 on both sides to move inwards along slide rod 323 to clamp and fix the heat sink 122. The multiple clamping plates 325 work together to clamp and fix the heat sink 122, making the fixation more stable and preventing the heat sink 122 from shifting due to equipment vibration. At this time, cylinder 312 drives C-frame 313 to move the heat sink 122 upwards via clamping plates 325, causing the base 121 to suspend and not contact other workpieces. This prevents the heat from the base 121 from being dissipated through heat conduction via other objects, ensuring the accuracy of the test results for the heat dissipation performance of the heat sink 122.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
