Description
Technical Field

[0002] An active vibration isolator is a device used to isolate vibrations. It reduces or eliminates vibration propagation through active control. Unlike traditional passive vibration isolators that rely on elastic and damping elements, active vibration isolators typically consist of sensors, controllers, and actuators. After production, active vibration isolators require testing on a test bench to ensure performance. Existing test benches are difficult to adjust quickly and easily to accommodate isolators of different sizes. This leads to frequent changes in testing equipment or significant time spent debugging the test bench during actual testing, greatly reducing testing efficiency and increasing testing costs. Therefore, this invention proposes an active vibration isolator test bench. Utility Model Content

[0027] Example
[0028] like Figure 1 As shown, the present invention proposes an active vibration isolator test bench, comprising: a test bench 1 for testing, wherein a set of guide grooves 2 are provided on the upper surface of the test bench 1; a support frame 3 fixedly disposed on the upper surface of the test bench 1, wherein the support frame 3 is configured in an "L" shape, a motor 4 is disposed on the upper surface of the support frame 3, and a cam 5 is fixedly disposed on the output end of the motor 4 for driving the cam 5 to rotate; a test component 6 disposed on the support frame 3 for testing the active vibration isolator, which can stably test the active vibration isolator; and a fixing component 7 fixedly disposed on the upper surface of the test bench 1 for limiting the active vibration isolator, which facilitates fixing and limiting active vibration isolators of different sizes and improves the stability of the test.
[0029] like Figure 1 and Figure 2 As shown, the test assembly 6 includes a fixed rod 61 that runs through the support frame 3, allowing the fixed rod 61 to move vertically up and down. A first limiting nut 62 is threaded onto the upper end of the fixed rod 61, and a first spring 63 is sleeved on the outer wall of the fixed rod 61. One end of the first spring 63 is fixedly connected to the support frame 3, and the other end of the first spring 63 is fixedly connected to the first limiting nut 62, enabling the fixed rod 61 to move stably. A test pressure head 64 is fixedly connected to the lower end of the fixed rod 61, facilitating the application of pressure to the active vibration isolator by driving the test pressure head 64. A second limiting nut 65 is threaded onto the outer wall of the fixed rod 61, and a second spring 66 is sleeved on the outer wall of the fixed rod 61. One end of the second spring 66 is fixedly connected to the support frame 3, and the other end of the second spring 66 is fixedly connected to the second limiting nut 65, enabling the fixed rod 61 to move more stably.
[0030] like Figure 1 and Figure 3As shown, the fixing assembly 7 includes a set of bidirectional threaded rods 71 fixedly mounted on the upper surface of the test bench 1. A support seat 72 is rotatably mounted between the bidirectional threaded rods 71, and a bearing is provided at the connection between the bidirectional threaded rods 71 and the support seat 72 to ensure stable rotation of the bidirectional threaded rods 71. One end of the bidirectional threaded rod 71 passes through the support seat 72 and extends to be connected to a handwheel 73, which facilitates manual rotation of the bidirectional threaded rod 71. A threaded sleeve block 74 is threadedly fitted onto the outer wall of the bidirectional threaded rod 71. One end of the threaded sleeve block 74 is fixedly connected to a limiting plate 75. An installation through hole 76 is opened on the upper surface of the limiting plate 75. A slider 77 is fixedly connected to one end of the limiting plate 75. The slider 77 is slidably connected to the guide groove 2, which facilitates the rapid movement of the installation through hole 76 on the limiting plate 75, thereby enabling limiting installation tests on active vibration isolators of different sizes and improving test efficiency.
[0031] like Figure 1 and Figure 2 As shown, a fixed base 8 is fixedly installed at the bottom of the motor 4. The fixed base 8 is fixedly connected to the support frame 3 by bolts, which can ensure the stability of the motor 4 installation and facilitate disassembly and assembly.
[0032] Furthermore, a stabilizing frame 9 is fixedly installed on the upper surface of the support frame 3. The stabilizing frame 9 is rotatably connected to the output end of the motor 4, which can ensure the stability of the output end of the motor 4.
[0033] In addition, support legs 10 are provided at the four corners of the bottom surface of the test bench 1, and rubber pads 11 are fixedly installed at the lower end of the support legs 10 to reduce the transmission of vibration.
[0034] Furthermore, the guide groove 2 and the slider 77 are designed with a "T" shape, which makes the sliding of the guide groove 2 and the slider 77 more stable.
[0035] In this embodiment, when testing active vibration isolators of different sizes is required, the operator rotates the handwheel 73, which drives the bidirectional threaded rod 71 to rotate. Due to the characteristics of the bidirectional threaded rod, its rotation causes the threaded sleeve block 74 to displace along the axial direction of the bidirectional threaded rod. The slider 77 connected to one end of the threaded sleeve block slides within the guide groove 2, ensuring the stability and straightness of the displacement, thereby moving the mounting through hole 76 on the limiting plate 75. The bolts then securely mount the brake vibration isolator to the limiting plate 75. This allows for quick and convenient adaptation to vibration isolators of different sizes without frequent changes to the testing equipment, enabling rapid fixing and limiting of vibration isolators of different sizes, and significantly shortening the test preparation time.
[0036] During testing: Motor 4 is started, and its output drives cam 5 to rotate. The rotation of cam 5 pushes the fixed rod 61 to move vertically up and down. During this vertical movement, the fixed rod 61 moves the first limit nut 62 and the second limit nut 65. The first limit nut 62 and the second limit nut 65 respectively extend and retract the first spring 63 and the second spring 66, thus ensuring the stable vertical movement of the test head 64 at the lower end of the fixed rod 61. This allows for the testing of the fixed active vibration isolator below, simulating the stress conditions during actual operation, thereby completing the performance test of the active vibration isolator, improving testing efficiency, and ensuring the accuracy and reliability of the test results.
[0037] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
