[0032] like Figures 1-4 As shown, this utility model provides a technical solution: a high-precision PCBA board material testing device, including a support plate 4, and further comprising:

[0033] Adjustment component 5 includes a first guide groove 51 located on the top of the support plate 4, a sliding block 52 slidably mounted on the first guide groove 51, a moving rod 53 located at the bottom of the sliding block 52, an auxiliary rod 54 located at the bottom of the support plate 4, a sliding guide seat 55 slidably mounted inside the auxiliary rod 54, and a second guide groove 56 located at the top of the sliding guide seat 55. The moving rod 53 is engaged with the sliding guide seat 55 and the second guide groove 56. The first guide groove 51 is fixed to the top of the support plate 4, providing a lateral sliding track for the sliding block 52, and is driven by a power source. As it moves, the moving rod 53 at the bottom of the sliding block 52 moves accordingly and engages with the second guide groove 56 at the top of the sliding guide seat 55. The auxiliary rod 54 is located at the bottom of the support plate 4, and the sliding guide seat 55 inside it can slide along it, driving the moving rod 53 to move synchronously. Through the bidirectional sliding of the sliding block 52 and the sliding guide seat 55, the moving rod 53 moves in conjunction in the cross-shaped guide structure, driving the pressure component 6 to be precisely positioned at any position in the plane, realizing pressure test coverage of different test points on the surface of the PCBA board, and improving the adaptability and positioning accuracy of the equipment to diverse test scenarios.

[0034] The pressurizing assembly 6 includes a pressing column 63 located at the bottom of the moving rod 53. A fixing plate 61 is mounted on the pressing column 63, and a telescopic rod 62 is mounted on the top of the fixing plate 61. The top of the telescopic rod 62 is fixedly connected to the bottom of the sliding guide seat 55. A pressure plate 64 is mounted on the bottom of the pressing column 63. The pressurizing assembly 6 achieves pressure testing of the sheet metal through the cooperation of multiple components. The top of the telescopic rod 62 is fixed to the bottom of the sliding guide seat 55, and the bottom is connected to the fixing plate 61, driving the pressing column 63 to rise and fall. The pressure plate 64 at the bottom of the pressing column 63 directly contacts the sheet metal to transmit the test pressure. The fixing plate 61 serves as the connection hub between the telescopic rod 62 and the pressing column 63, ensuring stable force transmission. Through the telescopic control of the telescopic rod 62, the pressure plate 64 can apply pressure with different heights, strokes, and intensities to complete mechanical property tests such as sheet metal pressure resistance and bending, adapting to diverse testing needs.

[0035] Furthermore, such as Figures 1-3As shown: a support column 3 is provided at the bottom of the support plate 4, and a base 1 is provided at the bottom of the support column 3. The support plate 4 is connected to the base 1 through the support column 3.

[0037] Working principle: such as Figures 1-5 As shown, base 1 serves as the basic support structure, connected to support plate 4 via support column 3 to ensure overall stability of the equipment. In clamping assembly 2, guide base 21 is fixed to the top of base 1. Power supply causes sliding rod 22 to move along guide base 21, driving top moving seat 23 to adjust its position. The snap-fit ​​plate 24 on top of moving seat 23 initially positions the edge of the plate through snap-fit ​​groove 29. After the drive power supply 25 is started, it drives rotating plate 26 to rotate around snap-fit ​​plate 24, causing pressure plate 27 at the other end to press down. Bottom damping spring 28 provides elastic preload, firmly clamping the plate between snap-fit ​​plate 24 and pressure plate 27, achieving multi-dimensional fixation of the plate. In adjustment assembly 5, first guide groove 51 is fixed to the top of support plate 4. Power supply drives sliding block 52 to slide laterally along it. The bottom of sliding block 52... The movable rod 53 moves and engages with the second guide groove 56 at the top of the sliding guide seat 55. The auxiliary rod 54 is located at the bottom of the support plate 4. The sliding guide seat 55 inside the auxiliary rod 54 can slide along the auxiliary rod 54, causing the movable rod 53 to move synchronously. Through the bidirectional sliding of the sliding block 52 and the sliding guide seat 55, the movable rod 53 moves in conjunction in the cross-shaped guide structure, driving the pressurizing component 6 to be precisely positioned at any position in the plane. The top of the telescopic rod 62 of the pressurizing component 6 is fixed to the bottom of the sliding guide seat 55, and the bottom is connected to the fixed plate 61, driving the lower pressure column 63 to rise and fall. The pressure plate 64 at the bottom of the lower pressure column 63 directly contacts the plate and transmits the test pressure. Through the telescopic control of the telescopic rod 62, the pressure plate 64 can achieve pressure application with different heights, strokes and intensities, completing the mechanical property tests of the plate such as pressure resistance and bending.
