DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-4, the utility model provides an embodiment: a test fixture for a heat sink with a high aspect ratio, including a test table 1, a mounting support frame 2 is installed on the upper end of the test table 1, a cylinder 3 is installed on one side of the mounting support frame 2, a mounting plate 4 is installed on the lower end of the cylinder 3, a connecting plate 5 is installed below the mounting plate 4, a test device box 6 is installed below the connecting plate 5, a limited slide seat 8 is installed on the other side of the mounting support frame 2, a limited slide bar 9 is arranged above one end of the connecting plate 5, linear motors 10 are installed on both sides above the test table 1, a support plate 11 is installed above the linear motor 10, a support seat 14 is installed above the support plate 11, positioning seats 13 are installed on both sides of the support seat 14, and a limited placement seat 15 is installed above the support seat 14. It should be noted that in order to save space and highlight the innovative elements of this patent, such as the specific detection method and detection principle of the heat sink by the detection device box, they will not be repeated in this patent.

[0023] When in use, the linear motor 10 is turned on to make the sliding seat 12 drive the support plate 11 to move, so that the shockproof heat sink can be moved to a suitable position for detection. At this time, the positioning rod 7 is located directly above the positioning seat 13, and then the cylinder 3 is turned on to make the mounting plate 4 push the connecting plate 5 to move, and the detection device box 6 is moved through the connecting plate 5. At this time, the positioning rod 7 is installed into the positioning groove 1301 set in the positioning seat 13, and then the height, length and width of the heat sink 16 are detected through the components installed inside the detection device box 6. A limiting slide bar 9 is set at one end of the connecting plate 5. When the connecting plate 5 moves, the limiting slide bar 9 moves vertically along the direction of the limiting slide seat 8. In this way, the connecting plate 5 can move with the detection device box 6 for positioning, thereby avoiding displacement during the movement of the detection device box 6.

[0024] See also Figure 1 and Figure 2 The mounting support frame 2 is welded to the testing platform 1, and a mounting seat 301 is provided at one end of the cylinder 3. The mounting seat 301 and the testing platform 1 are fixedly connected by a fixing screw 302. One end of the fixing screw 302 passes through the mounting seat 301 and extends to the inside of the testing platform 1, which can make the structure between the mounting support frame 2 and the testing platform 1 more solid. The mounting seat 301 and the testing platform 1 can be easily installed and fixed by the set fixing screw 302.

[0025] See also Figure 1 and Figure 2 Positioning rods 7 are provided on both sides of the lower end of the connecting plate 5. Two positioning rods 7 are provided. The two positioning rods 7 are symmetrical about the vertical center line of the connecting plate 5. The installed positioning rods 7 can position the connecting plate 5 and the positioning seat 13, thereby avoiding offset and affecting the detection of the heat sink.

[0026] See also Figure 2 There are two limit slides 8, and the limit slide rod 9 and the connecting plate 5 are an integrated structure. The limit slide rod 9 is arranged corresponding to the limit slide 8. One end of the limit slide rod 9 passes through the limit slide 8 and extends to the outside of the limit slide 8, which can make the structure between the limit slide rod 9 and the connecting plate 5 more solid. Through this arrangement, the connecting plate 5 can be moved vertically along the direction of the limit slide 8 through the limit slide rod 9.

[0027] See also Figure 1 , Figure 2 and Figure 3 There are two linear motors 10, which are symmetrical about the vertical center line of the detection platform 1. A sliding seat 12 is installed at the lower end of the support plate 11. The sliding seat 12 is arranged corresponding to the linear motor 10. By turning on the linear motor 10, the sliding seat 12 can drive the support plate 11 to move, so that the shockproof heat sink can be moved to a suitable position for detection.

[0028] See also Figure 1 and Figure 2 There are two positioning seats 13, and the two positioning seats 13 are symmetrical about the vertical center line of the support plate 11. A positioning groove 1301 is provided inside the positioning seat 13. The positioning seat 13 is arranged corresponding to the positioning rod 7. By installing the positioning seat 13, the positioning rod 7 and the positioning seat 13 can be aligned and installed.

[0029] See also Figure 1 and Figure 4 A limiting placement groove 1501 is arranged inside the limiting placement seat 15, and a heat sink 16 is placed inside the limiting placement groove 1501. This arrangement can conveniently limit the placement of the heat sink 16 to avoid shaking of the heat sink 16 during movement, thereby affecting the detection of the heat sink 16.

[0030] Working principle: When in use, the heat sink 16 to be detected is placed inside the limit placement groove 1501 set by the limit placement seat 15, and then the linear motor 10 is turned on to make the sliding seat 12 drive the support plate 11 to move, so that the shockproof heat sink can be moved to a suitable position for detection. At this time, the positioning rod 7 is located directly above the positioning seat 13, and then the cylinder 3 is turned on to make the mounting plate 4 push the connecting plate 5 to move, and the detection device box 6 is moved through the connecting plate 5. At this time, the positioning rod 7 is installed into the positioning groove 1301 set by the positioning seat 13, and then the height, length and width of the heat sink 16 are detected through the components installed inside the detection device box 6. A limit slide bar 9 is provided at one end of the connecting plate 5. When the connecting plate 5 moves, the limit slide bar 9 moves vertically in the direction of the limit slide seat 8. In this way, the connecting plate 5 can move with the detection device box 6 for positioning, thereby avoiding the deviation of the detection device box 6 during the movement, thereby affecting the detection effect of the detection device box 6.
