Description

Technical Field

[0001] The invention belongs to the technical field of computer hardware mainboard detection, and in particular relates to a computer hardware mainboard strength detection device. Background Art

[0002] A computer hardware motherboard is a circuit board, also known as a mainboard, motherboard, or system board. It is the core component of a computer system. It connects and communicates with the CPU, memory, storage devices, graphics cards, and other components, and provides power, interfaces, and expansion slots. Motherboard strength testing devices help manufacturers, engineers, and researchers assess the structural strength and stability of motherboards, ensuring that their design and manufacturing meet engineering requirements and maintain stability and reliability under various conditions.

[0003] The existing motherboard testing method is to clamp the motherboard horizontally, and then apply planar pressure to the motherboard through hydraulic means to complete the test. However, when the existing motherboard is in use, it is usually fixed vertically with bolts passing through the mounting holes, which is different from the horizontal clamping installation method used in existing testing, making this testing method unable to truly reflect the strength of the motherboard during actual use. Secondly, since there are many components of different heights installed on the front of the motherboard, when the existing method applies pressure to the motherboard, the pressure is mainly indirectly transmitted to the motherboard through the highest component, causing the pressure area of ​​the motherboard to change continuously, and then causing a difference between the applied pressure and the pressure on the motherboard. This not only increases the detection error, but also makes the pressure applied to the motherboard uneven, making it difficult to truly reflect the strength of the motherboard.

Then the compression spring is closed, and the telescopic hydraulic cylinder continues to extend to continue to apply pressure to the computer hardware motherboard, thereby performing strength testing on the computer hardware motherboard, thereby solving the problem that the existing method indirectly transmits pressure through components, resulting in a difference between the applied pressure and the pressure exerted on the motherboard, which not only increases the detection error, but also makes the pressure applied to the motherboard uneven, making it difficult to truly reflect the strength of the motherboard.

[0017] 3.

The installed through hole passes through the corner push rod 166 or the side push rod 178, and then the electromagnet 192 is energized to attract the permanent magnet 195 to move along the rectangular slide rod 193, so that the clamping plate 196 presses the edge of the computer hardware motherboard, and then the telescopic rod 176 is shortened, driving the side limit block 172 and the connecting rod 175 to move along the rectangular plate 171, and the connecting rod 175 will drive the side limit blocks 172 at both ends to move downward until the rectangular plate 171 and the side limit block 172 press and fix the computer hardware motherboard, thereby simulating the state of the motherboard in actual use, thereby solving the problem that the existing detection method cannot truly reflect the strength of the motherboard in actual use.

[0028] Among them, the right-angle plate 161, the corner rectangular block 165, the corner limit spring 167, the rectangular plate 171, the side rectangular block 177, and the side limit spring 179 are all fixedly connected to the movable slider 15, both ends of the connecting rod 175 are fixedly connected to the corner limit block 162, the telescopic rod 176 is fixedly connected to the rectangular plate 171 and the movable slider 15, the bottom block 191 is fixedly connected to the connecting block 18, the two clamping mechanisms 19 are symmetrically arranged, the drive motor 201 is fixedly connected to the connecting block 18, the two threaded rods 204 are rotatably connected to the connecting block 18, the two threaded rods 204 are threadedly connected to the two movable sliders 15, and the two fixed blocks 205 are fixed The plate 13 is fixedly connected, the diaphragm 12 is made of soft material, and the interior of the oil storage shell 6, the outer ring 10, the inner ring 11, and the diaphragm 12 on the left side of the sliding plate 7 are all filled with liquid.

Then the connecting seat 2 is moved to the appropriate position and fixed, thereby completing the bending test of one end of the motherboard; the middle part of the computer hardware motherboard is fixed by the clamping mechanism 19, and the bending test of both ends is performed, thereby greatly improving the scope of use of the present invention.

[0029] Working principle:

[0030] Before the present invention is used, the sliding block 4 is located at the lower end of the sliding shaft 3, the telescopic hydraulic cylinder 5 is in the shortest state, the control valve 9 is in the closed state, the two movable sliders 15 are located at the two ends of the sliding groove 14, and the telescopic rod 176 is in the longest state;

[0031] When the present invention is used, the driving motor 201 works, driving the driving gear 202 to rotate, and the driving gear 202 drives the meshing transmission gear 203 to rotate, and the two threaded rods 204 rotate, thereby causing the upper and lower movable sliders 15 to move closer to the connecting block 18 along the sliding groove 14. When the distance between the two movable sliders 15 is adapted to the size of the computer hardware motherboard to be tested, the driving motor 201 will stop working and the two movable sliders 15 will no longer move;

[0032] The computer hardware motherboard to be tested is placed on the surface of the corner rectangular block 165, the side rectangular block 177, and the bottom block 191. The through hole for installation passes through the corner push rod 166 or the side push rod 178. Then the electromagnet 192 is energized to attract the permanent magnet 195 to move along the rectangular slide rod 193, so that the clamping plate 196 presses the edge of the computer hardware motherboard. Then the telescopic rod 176 is shortened, driving the side limit block 172 and the connecting rod 175 to move along the rectangular plate 171. The connecting rod 175 will drive the side limit blocks at both ends. 172 moves downward until the rectangular plate 171 and the side limit block 172 press and fix the computer hardware motherboard. During this process, since the force required for the deformation of the side limit spring 2 179 is greater than the force required by the side limit spring 173, after the side push rod 178 contacts the side push plate 174, the side push rod 178 pushes the side push plate 174 to squeeze the side push plate 174, so that the side push rod 178 penetrates into the side limit block 172, and the side push rod 178 limits the computer hardware motherboard. The same applies to the corner push rod 166.

[0033] After the computer hardware motherboard is fixed, the connecting seat 2 is slid upward to the middle of the computer hardware motherboard and fixed. Then the telescopic hydraulic cylinder 5 is extended, driving the diaphragm 12 close to the computer hardware motherboard. During the process, the control valve 9 is opened. When the diaphragm 12 is in contact with the computer hardware motherboard, the diaphragm 12 squeezes the internal liquid into the oil reservoir 6 and pushes the sliding piece 7 to slide to the right and squeeze the compression spring 8 until the diaphragm 12 is adapted to the computer hardware motherboard. Then the compression spring 8 is closed, and the telescopic hydraulic cylinder 5 continues to extend to continue to apply pressure to the computer hardware motherboard, thereby performing a strength test on the computer hardware motherboard.

[0034] When the computer hardware motherboard is subjected to bending test at one end, the two movable sliders 15 will be located at both ends of the sliding groove 14, and one end of the computer hardware motherboard will be fixed by the upper or lower corner fixing mechanism 16 and the side fixing mechanism 17, while the other end will not exceed the connecting block 18. Then the connecting seat 2 is moved to the appropriate position and fixed. The remaining steps are the same as the strength test. When the bending test at both ends is performed, the middle part of the computer hardware motherboard is fixed by the clamping mechanism 19, and the remaining steps are the same as the one-end bending test.
