Technical Field
[0001] This utility model belongs to the field of performance testing technology for finished wood products, and in particular relates to a device for testing the performance of finished wood products. Background Technology
[0002] Timber product performance testing is a process of conducting a series of tests on timber products to evaluate their physical and mechanical properties, ensuring that these products meet specific standards and usage requirements.
[0003] Traditional wood performance testing often relies on manual operation or semi-automatic equipment, making it difficult to precisely control the applied load location. This can lead to insufficient accuracy and poor repeatability of test results. Previous testing equipment was typically designed for specific types of wood or testing conditions, lacking flexibility. For example, evaluating the performance of different wood species in various environments may require different support conditions or simulations of different usage scenarios, but traditional equipment struggles to be quickly and easily adjusted to meet these needs. Ensuring the stability and safety of the testing platform is crucial during high-intensity load testing. If the wood sample slips or moves during the test, it will not only affect the accuracy of the test results but may also pose safety hazards.
[0004] To address these issues, we provide a device for testing the performance of finished wood products. Utility Model Content

The movable test assembly 500 includes a transverse linear guide rail 50. 1. A motor 502 fixed to the end of the transverse linear guide 501; a transverse moving seat 503 adapted to be installed inside the transverse linear guide 501; a vertical linear guide 504 fixed to the transverse moving seat 503; a motor 505 fixed to the top of the vertical linear guide 504; and a vertical moving seat 506 adapted to be installed inside the vertical linear guide 504. Through the transverse and vertical adjustment of the moving test assembly 500, the position of applying load to the wood can be precisely controlled, making the test more flexible and targeted, while improving the automation and efficiency of the test process.
[0028] The vertical moving seat 506 has a load-loading end 600 fixed on its outer side. The load-loading end 600 is equipped with a test end 601 on its lower side. The load-loading end 600 can adjust the load according to different test requirements, thereby evaluating the performance of wood under different stresses and helping to fully understand the mechanical properties of wood.
[0029] Specifically, the horizontal linear guide 501 and the vertical linear guide 504 are arranged perpendicularly, and both the horizontal linear guide 501 and the vertical linear guide 504 are ball screw structures. The load loading end 600 is interconnected with the external control end via a connecting line, and different loads can be applied through control. The lower end of the test end 601 is lower than the lower end of the vertical linear guide 504.
[0030] The test bench 100 has a wood board to be tested on its upper side. The positioning plate 204 clamps and presses the wood board to be tested against its side to ensure that the wood remains stable during the test, reduce measurement errors caused by wood movement, and improve test accuracy.
[0031] Furthermore, a filling area 101 is provided in the middle recess of the test bench 100. The filling area 101 is located directly below the test end 601. The filling area 101 can be fitted with panels of different materials. The panels are flush with the upper side of the test bench 100.

The transverse linear guide rail 501 is fixed to the side of the horizontal plate 400.
[0033] The specific operation steps of this embodiment are as follows: First, place the wood board to be tested on the upper side of the test bench 100, ensuring that it is located above the filling area 101. Select a suitable panel to replace it in the filling area 101 according to the test requirements to simulate different support conditions or test environments. Then, drive the traction plate 203 and connecting rod 202 to move through the hydraulic cylinder 201 in the positioning component 200, so that the positioning plate 204 clamps and presses the side of the wood board, ensuring that the wood remains stable during the test and reducing measurement errors caused by the movement of the wood. Next, start the moving test component 500, and drive the horizontal moving seat 503 and vertical moving seat 506 on the horizontal linear guide rail 501 and vertical linear guide rail 504 respectively through the motor 1 502 and the motor 2 505, precisely adjust the position of the load loading end 600 and the test end 601 below it, so that it is aligned with the position of the wood to be loaded. Adjust the load loading end 600 to apply different loads through the external control terminal to evaluate the performance of the wood under different stresses.
