Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a comprehensive mechanical testing machine for furniture. Background Technology

[0002] Comprehensive mechanical testing of furniture is a key step in evaluating furniture performance. It is mainly used to test the core indicators of furniture such as stability, stiffness, strength and durability under different stress conditions.

[0003] Currently, during testing, it is typically necessary to manually install limiting plates on the testing platform according to the furniture style to prevent significant displacement of the seat during testing. However, existing methods often involve fixing the limiting plates to the four corners of the furniture with bolts. This requires disassembly and readjustment every time the test furniture is changed, which is cumbersome and inefficient. Furthermore, due to the variety of furniture styles, to ensure the accuracy and consistency of test data, it is also necessary to replace the corresponding push end blocks according to different situations, which further increases the workload of debugging.

[0004] Therefore, there is an urgent need to design a comprehensive mechanical testing machine for furniture to achieve rapid clamping, automatic adaptation to various furniture structures, and convenient replacement of test components, thereby improving testing efficiency and standardization. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a comprehensive mechanical testing machine for furniture.

[0006] The technical implementation scheme of this utility model is as follows: A comprehensive mechanical testing machine for furniture includes a base, a support frame, an electric slide rail one, an electric slide rail two, an electric push rod one, a drive assembly, a clamping plate, a loading and unloading component, and contact blocks. The support frame is provided on the base. Electric slide rail one is installed on the upper and lower sides of the support frame. Electric slide rail two is provided between the sliders of two electric slide rail one on the same side. Electric push rod one is installed on the slider of each electric slide rail two. The telescopic end of electric push rod one is located inside the support frame. The telescopic end of electric push rod one is also provided with a loading and unloading component. A contact block is detachably provided on the loading and unloading component to place the test furniture on the base. Then, the electric push rod one drives the corresponding contact block to apply pressure toward the test furniture. The drive assembly is provided on the base. Clamping plates for limiting the position of the test fixture are provided on the moving parts on both sides of the drive assembly. Guide grooves for the movement of the clamping plates on both sides are provided on the base.

[0007] Optionally, the drive assembly includes a motor mounted on the base, a bidirectional threaded rod rotatably between the two inner walls of the guide groove, the shaft end of the bidirectional threaded rod being connected to the output end of the motor, and symmetrically sliding moving blocks within the guide groove, the two moving blocks being threadedly connected to one side of the bidirectional threaded rod, and the two clamping plates being connected to one side of the moving blocks.

[0008] Optionally, the loading and unloading components include mounting plates installed on one telescopic end of each electric push rod, each mounting plate being equipped with a sensor, and each mounting plate also having a plug that engages with the corresponding contact block.

[0009] Optionally, it also includes guide sleeves disposed on both sides of the housing of each electric actuator, with a sliding rod slidably disposed on the guide sleeve, the end of the sliding rod being connected to the corresponding mounting plate.

[0010] Optionally, the base may also include an assembly plate, with one assembly plate disposed around each of the four sides of the base.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0021] Example: A comprehensive mechanical testing machine for furniture, such as Figures 1-4 As shown, the system includes a base 1, a support frame 2, electric slide rail 1 3, electric slide rail 2 31, electric push rod 1 4, a drive assembly, a clamping plate 10, mounting and dismounting parts, and a contact block 14. The base 1 serves as the foundation platform for the overall structure, supporting the test furniture 5 and other functional components. The support frame 2 is fixedly mounted on the base 1. The support frame 2 is a hollow frame that serves as the main support structure for subsequent adjustment components. Electric slide rails 1 3 are mounted on the upper and lower sides of the support frame 2. Electric slide rail 2 31 is positioned between the sliders of two electric slide rails 1 3 on the same side. Each slider of electric slide rail 2 31 is equipped with an electric push rod 1 4. The telescopic ends of electric push rod 1 4 are located inside the support frame 2, and mounting and dismounting parts are also provided on the telescopic ends of electric push rod 1 4. A detachable connector is provided on the mounting and dismounting parts. The detachable design of the contact block 14 allows for easy replacement of contact modules of different shapes or sizes according to different testing needs, thus adapting to various force simulation scenarios. The extension and retraction of the electric push rod 4 drives the corresponding contact block 14 to apply pressure to the test furniture 5. Different contact blocks 14 apply pressure to different parts of the test furniture 5 to achieve mechanical testing of the test furniture 5. To ensure that the test furniture 5 does not shift or deviate during the test, a drive assembly is installed on the base 1. Clamping plates 10 are provided on the moving parts on both sides of the drive assembly to limit the position of the test fixture and clamp the test furniture 5. The base 1 has guide grooves 6 for the movement of the clamping plates 10 on both sides to ensure that the clamping process is stable and reliable.

[0022] In summary, the above structure constructs a furniture mechanical testing device that integrates automated clamping, multi-directional adjustment, and modular loading. It has the advantages of simple operation, accurate testing, and wide applicability, and can effectively meet the high standards required by the modern furniture industry for mechanical performance testing.

[0023] like Figure 3 As shown, the drive assembly includes a motor 8 mounted on the base 1, a bidirectional threaded rod 7 rotating between the two inner walls of the guide groove 6, the shaft end of the bidirectional threaded rod 7 being connected to the output end of the motor 8, and symmetrically sliding moving blocks 9 within the guide groove 6. The two moving blocks 9 are respectively threadedly connected to one side of the bidirectional threaded rod 7, and the two clamping plates 10 are respectively connected to one side of the moving blocks 9. The motor 8 drives the bidirectional threaded rod 7 to rotate, causing the two moving blocks 9 to move synchronously in opposite directions, thereby achieving automatic centering and clamping of the clamping plates 10, ensuring the stable positioning of the test furniture 5.

[0024] like Figure 4 As shown, the mounting and unloading components include mounting plates 11 installed on the telescopic ends of each electric push rod 4. Each mounting plate 11 is equipped with a sensor, specifically a pressure sensor, which is used to collect pressure data applied to the test furniture 5 in real time. The mounting plate 11 is also equipped with a plug rod 15 that engages with the corresponding contact block 14, thereby enabling the quick disassembly and replacement of the contact block 14.

[0025] like Figure 4 As shown, it also includes guide sleeves 12 disposed on both sides of the housing of each electric push rod 4. A sliding rod 13 is slidably disposed on the guide sleeve 12. The end of the sliding rod 13 is connected to the corresponding mounting plate 11. The guide sleeve 12 and the sliding rod 13 form a guide structure, which effectively prevents the electric push rod 4 from deviating or shaking during the pressure application process, and improves the linearity and repeatability of the pushing action.

[0026] like Figure 2 As shown, it also includes an assembly plate 16. An assembly plate 16 is provided on each of the four sides of the base 1. The assembly plate 16 can be used to connect external auxiliary equipment (such as protective covers, alarms, pneumatic systems, etc.) and reserve installation positions for subsequent functional upgrades.

[0027] like Figure 2 As shown, it also includes a searchlight 17, which is installed between the top two sides of the support frame 2. The searchlight 17 can provide sufficient local lighting in the test environment with insufficient light, making it easy to observe the test process and the deformation of the test furniture 5.

[0028] Optionally, the device also includes a mounting frame 18 and an electric push rod 19. Another electric slide rail 31 is provided between the two electric slide rails 3 at the top of the support frame 2. The mounting frame 18 is provided on the telescopic end of the other electric slide rail 31, and the electric push rod 19 is installed on the mounting frame 18. During testing, the worker suspends the steel ball on the electric push rod 19 and then starts the electric push rod 19. The telescopic end of the electric push rod 19 retracts inward. At this time, the telescopic end of the electric push rod 19 is retracted into itself, and the electric push rod 19 no longer provides support for the steel ball. The steel ball falls downward under the action of gravity and collides with the furniture 5 under test, thereby enriching the force simulation scenario and effectively improving the accuracy of the device test.

[0029] During use, the required contact block 14 is first prepared and fixedly installed onto the mounting plate 11 of the corresponding electric push rod 4 using the insertion rod 15, ensuring a secure connection of the contact block 14. Then, the test furniture 5 to be tested is placed on the base 1. Next, the motor 8 is started, driving the bidirectional threaded rod 7 connected to it to rotate. Under the action of the bidirectional thread, the moving blocks 9 on both sides slide synchronously along the guide groove 6, driving the clamping plate 10 to move towards the center, thereby fitting and clamping the test furniture 5, achieving its positioning and fixation. Once the position of the test furniture 5 is clamped and positioned, the next testing operation can proceed. Next, the electric slide rail 1 3 and electric slide rail 2 31 are started sequentially. Electric slide rail 1 3 drives electric slide rail 2 31 and the entire assembly to move horizontally to adjust the lateral testing position of the electric push rod 4; simultaneously, electric slide rail 2 31 can vertically adjust the height of the electric push rod 4, thereby achieving precise positioning of the contact block 14 in three-dimensional space, ensuring its alignment with the test part of the test furniture 5. After confirming the position is correct, the electric push rods 4, positioned around the perimeter, are activated. Their telescopic ends push the contact block 14 towards the test furniture 5, applying pressure to the furniture 5 in the horizontal, forward / backward, left / right, and vertical directions. During this process, the sliding rod 13 slides synchronously within the guide sleeve 12, providing guidance and support to ensure the stability and accuracy of the contact block 14's movement. Simultaneously, sensors monitor the applied pressure value in real time and feed the relevant data back to the control backend for recording and analysis until all testing tasks are completed.
