DETAILED DESCRIPTION

[0025] The following is a detailed description of a device for detecting the anti-fracture and pressure resistance performance of a computer hardware motherboard according to the present invention with reference to the accompanying drawings of the specification.

[0026] like Figures 1 to 6As shown, a device for detecting the anti-fracture and pressure resistance performance of a computer hardware motherboard of the present invention comprises a frame 1, a support seat 2, a motherboard clamping seat 3, a support rod 4, an L-shaped bracket 10, a detection pressure plate assembly and a blanking hole 14, the support seat 2 is symmetrically arranged on the left and right sides of the upper surface of the frame 1, the outer edges of the support seat are respectively hinged to the motherboard clamping seat 3, the L-shaped bracket 10 is arranged in the middle of the rear side of the frame 1, the detection pressure plate assembly is connected to the L-shaped bracket 10, the upper surface of the frame 1 is provided with a blanking hole 14, the pressure plate of the detection pressure plate assembly and the blanking hole, two support rods 4 are provided, and the two support rods 4 are arranged on the corresponding sides of the detection pressure plate assembly, one end of the support rod 4 is connected to the detection pressure plate assembly, and the other end of the support rod is connected to the motherboard clamping seat 3.

[0027] The detection plate assembly includes a second sleeve 5, a shift block 6, a pressure rod 7, a first sleeve 8, a spring 9, a detection cylinder 11 and a pressure plate 12. The output shaft of the detection cylinder 11 slides downward through the horizontal section of the L-shaped bracket 10. The bottom end of the output shaft of the detection cylinder 11 is coaxially fixedly connected with the pressure rod 7. The bottom end of the pressure rod 7 is provided with a pressure plate 12. The first sleeve 8 is rotatably sleeved on the outside of the pressure rod 7. The second sleeve 5 is rotatably sleeved on the outside of the first sleeve 8. A limited sliding groove is provided on the outer wall of the second sleeve 5. A shift block 6 is fixed on the outer wall of the first sleeve 8. The shift block 6 slides up and down or left and right along the limited sliding groove. The upper end of the second sleeve 5 is connected to the lower surface of the horizontal section of the L-shaped bracket 10 through the spring 9. The upper end of the spring is connected to the bottom wall of the horizontal section of the L-shaped bracket, and the lower end of the spring is connected to the top wall of the second sleeve.

[0028] The cross section of the pressure rod 7 is circular, and a circular ring 15 is integrally formed on the outer side wall of the pressure rod 7 . An annular groove matching the circular ring 15 is provided on the inner side wall of the first sleeve 8 .

[0029] The limiting slide groove includes a horizontal slide groove 17 and a vertical slide groove 16, and the horizontal slide groove 7 is connected with the vertical slide groove 16. The shift block 6 can slide in the horizontal slide groove 17 and the vertical slide groove 16 of the second sleeve 5 respectively as the first sleeve 8 rotates.

[0030] When the shift block 6 is located in the horizontal slot 17 of the second sleeve, the pressure rod 7, the first sleeve 8 and the second sleeve 5 move up and down together. When the detection cylinder 11 drives the pressure rod 7 to press down a short distance, the pressure plate has not yet contacted the test sample, but the second sleeve 5 drives the main board clamping seat 3 on both sides to rotate outward through the support rods 4 on both sides, so that the middle part of the test sample 13 is propped up, thereby realizing the pressure resistance test of the lower surface of the test sample; when the shift block 6 is located in the vertical slot 16 of the second sleeve 5, the second sleeve 5 does not move with the pressure rod 7 and the first sleeve 8 due to the tension of the spring 9, and the detection cylinder 11 drives the pressure rod 7 to press down until the pressure plate presses the upper surface of the test sample downward, thereby realizing the test of the upper surface of the test sample. After the upper surface of the test sample is squeezed and the lower surface is bent, if there is no breakage, it means that the product quality is qualified. If the test sample is broken, the broken sample is recovered through the blanking hole.

[0031] The mainboard clamping seat 3 includes a first horizontal plate 301, a second horizontal plate 302, a vertical plate 303 and a tightening bolt 304. The bottom end of the vertical plate 303 is located at the outer edge of the support seat 2 and is hinged to the support seat 2. The first horizontal plate 301 and the second horizontal plate 302 are parallel to each other and a space is left between them for placing the test sample 13. The surface of the second horizontal plate 302 is threadedly connected with a tightening bolt 304.

[0032] The lower end of the tightening bolt 304 is a smooth spherical surface that can reduce damage to the test sample. It is tightened on the surface of the test sample 13 so that the test sample 13 can move relative to the tightening bolt 304. To reduce the damage of the tightening bolt 304 to the test sample 13, there are three tightening bolts 304 on each side.

[0033] The lower surface of the pressing plate is a smooth curved surface convex downward, so that the test sample 13 can move relative to the pressing plate 12, thereby reducing the damage of the pressing plate 12 to the test sample 13.

[0034] One end of the support rod is hinged to the outer wall of the second sleeve of the detection plate assembly, and the other end is hinged to the upper end of the vertical plate of the mainboard clamping seat. When the second sleeve 5 moves downward, the upper end of the support rod 4 moves downward, and the lower end of the support rod 4 generates a downward and outward force on the mainboard clamping seat 3, so that the mainboard clamping seat 3 can rotate. Figure 6 The lower end of the tightening bolt 304 is a smooth spherical surface and is pressed against the surface of the test sample 13, so that the test sample 13 can move relative to the tightening bolt 304. When the mainboard clamping seat 3 rotates, the clamping parts at both ends of the test sample 13 also change, thereby supporting the clamped sample upward and testing the fracture resistance and pressure resistance of the lower surface of the sample.

[0035] The present invention can detect the upper and lower surfaces of the test sample 13 without turning over, thereby improving the efficiency of the detection. When the shift block 6 is located in the horizontal slide groove 17 of the second sleeve 5, the pressure rod 7, the first sleeve 8 and the second sleeve 5 move up and down together, and when the detection cylinder 11 drives the pressure rod 7 to press down a short distance, the pressure plate 12 has not yet contacted the test sample 13, but at this time, the second sleeve 5 drives the main board clamping seats 3 on both sides to rotate outward through the support rods 4 on both sides, so that the middle part of the test sample 13 is propped up, thereby realizing the detection of the lower surface of the test sample 13; when the shift block 6 is located in the vertical slide groove 16 of the second sleeve 5, the second sleeve 5 does not move with the pressure rod 7 and the first sleeve 8 due to the tension of the spring 9, and the detection cylinder 11 drives the pressure rod 7 to press down until the pressure plate 12 presses the upper surface of the test sample 13 downward, thereby realizing the detection of the upper surface of the test sample 13.

[0036] The above description is only used to illustrate some principles of the present invention. This specification is not intended to limit the present invention to the specific structure and application scope shown and described. Therefore, all corresponding modifications and equivalents that may be used belong to the patent scope applied for by the present invention.
