[0002] The durability test of the shock absorber buffer pad is to conduct continuous or repeated loading tests on the shock absorber buffer pad by simulating the dynamic loads and environmental conditions borne by the shock absorber during actual vehicle driving, so as to evaluate its durability performance and reliability under long-term use.

[0003] The special test bench for durability testing of shock absorber buffer pads includes a test bracket for fixing and supporting the shock absorber buffer pad, a loading system (hydraulic cylinder) for simulating the dynamic loads borne by the shock absorber during actual operation, a control system for controlling the test process, including setting, adjusting and real-time monitoring of test parameters, a data acquisition system, and a test result display system. The data acquisition system is used to collect various data during the test process in real time, and the test result display system is used to display the real-time data and final results during the test process.

[0004] At present, a test block with a detection sensor is configured on the test bracket for fixing and supporting the shock absorber buffer pad. The loading system pushes the downward block to reciprocate downward to apply a certain load to the buffer pad, and cooperates with the test block to conduct durability testing on the shock absorber buffer pad. At present, the installation height of the downward block of the test bench is fixed, so that the test bench can only adapt to the durability testing of shock absorber buffer pads of one specification, and the applicable range is limited. Summary of the Utility Model

[0005] The technical problem to be solved by the present invention is that in the above-mentioned prior art, since it can only adapt to shock absorber buffer pads of one specification and cannot be used to test products of other specifications, this limits the universality of its application. If shock absorber buffer pads of different specifications need to be tested, different test equipment is required, which increases the test time and complexity.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] A special test bench for durability of shock absorber buffer pads includes a bracket, a downward block and a lifting seat. A fixed seat is provided on the bracket, and a vertical guide rail is provided on the fixed seat; the downward block is fixed at the bottom of the lifting adjustment plate, and the downward block cooperates with the top of the shock absorber buffer pad for alignment and limitation, and the installation height of the downward block is adjusted by an adjustment bolt; the guide groove A at the rear of the lifting seat is guided and slid by the vertical guide rail, and the adjustment bolt at the top of the lifting adjustment plate penetrates through the lifting seat and is locked and positioned by a locking nut above the lifting seat.

[0008] Preferably, an upper support is fixedly provided on the top of the bracket, a descending hydraulic cylinder is fixedly provided on the upper support, and the end of the hydraulic rod on the descending hydraulic cylinder is fixedly connected to the lifting seat.

[0009] The downward hydraulic cylinder is fixedly connected to the lifting seat through the end of the hydraulic rod, which can effectively transmit hydraulic power and drive the lifting seat to move up and down.

[0010] Preferably, the locking nut is threadedly sleeved on the outer side of the adjusting bolt.

[0011] Through the threaded connection, the operator can easily turn the locking nut to adjust the position of the adjusting bolt, thereby changing the height of the lifting adjustment plate.

[0012] Preferably, the outer side surface of the adjusting bolt is sleeved with a spring located between the lifting adjustment plate and the lifting seat.

[0013] The spring can absorb and buffer the vibration generated during the test, improving the stability and durability of the durability test bench.

[0014] Preferably, the guide block on the rear side of the lifting adjustment plate cooperates with the guide groove B at the bottom of the lifting seat for sliding guidance.

[0015] Preferably, a support platform is fixed on the lower support at the bottom of the bracket, a guide seat is fixed on the top of the support platform, a linear module is embedded in the guide seat, a moving seat that cooperates with the guide seat for guiding and sliding is provided on the moving slide of the linear module, and a test block with a detection sensor is fixed on the top of the moving seat.

[0016] Preferably, the test block cooperates with the bottom end of the shock absorber buffer pad for positioning and limiting, and the test block is arranged vertically corresponding to the descending block.

[0017] After the test is completed, the linear module drives the moving seat to move to the loading and unloading station, thereby causing the position of the test block to be staggered relative to the downward hydraulic cylinder, so that when the operator loads and unloads the shock absorber cushion above the test block at the loading and unloading station, it will not be affected by the downward hydraulic cylinder, thereby ensuring the safety of the operator.

[0018] Compared with the prior art, the technical effects and advantages of the utility model are:

[0019] This special test bench for the durability of shock absorber cushions has a downward hydraulic cylinder fixedly connected to a lifting seat through the end of a hydraulic rod. The hydraulic system provides power to drive the lifting seat to move up and down to simulate the dynamic load of the shock absorber in an actual vehicle. By turning the locking nut, the position of the adjusting bolt is adjusted, changing the height of the lifting adjustment plate, and further adjusting the installation height of the downward block to adapt to shock absorber cushions of different specifications. The spring on the outer side of the adjusting bolt is used to absorb and buffer vibrations during the test, improving the stability and durability of the test bench. The cooperation between the guiding block and the guiding groove ensures the linear movement of the lifting adjustment plate during movement, avoiding shaking and deviation. A linear module is embedded in the guiding seat, and the moving seat on the moving slide can move precisely. It cooperates with a test block with a detection sensor to conduct durability tests. The test block is aligned and limited with the bottom end of the shock absorber cushion, and is vertically correspondingly arranged with the downward block to achieve accurate loading.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] The following will further elaborate on this application Figures 1-4 for a more detailed description.

[0029] The embodiment of this application discloses a special test bench for the durability of a shock absorber buffer pad, which includes a bracket 1, a downward moving block 4, and a lifting seat 7. A upper support 10 is fixedly provided at the top of the bracket 1, and a downward hydraulic cylinder 11 is fixedly provided on the upper support 10. The end of the hydraulic rod of the downward hydraulic cylinder 11 is fixedly connected to the lifting seat 7. The downward hydraulic cylinder 11 is fixedly connected to the lifting seat 7 through the end of the hydraulic rod, which can effectively transmit hydraulic power and drive the lifting seat 7 to move up and down. The use of the hydraulic system ensures that the movement of the lifting seat 7 is smooth and controllable, which is crucial for simulating the dynamic load during actual vehicle driving.

[0030] A fixed seat 2 is provided on the bracket 1, and a vertical guide rail 3 is provided on the fixed seat 2; the downward moving block 4 is fixed to the bottom of the lifting adjustment plate 5 and the top end of the downward moving block 4 is aligned and limited with the shock absorber buffer pad, and the installation height of the downward moving block 4 is adjusted by an adjustment bolt 6; the guide groove A8 at the rear side of the lifting seat 7 is slidably guided in cooperation with the vertical guide rail 3, and the adjustment bolt 6 at the top of the lifting adjustment plate 5 penetrates through the lifting seat 7 and is locked and positioned by a locking nut 9 above the lifting seat 7. The locking nut 9 is threadedly sleeved on the outer side of the adjustment bolt 6. Through the threaded connection, the operator can conveniently turn the locking nut 9 to adjust the position of the adjustment bolt 6, thereby changing the height of the lifting adjustment plate 5. The locking nut 9 can accurately lock the position of the adjustment bolt 6 to ensure the stability of the lifting adjustment plate 5 and the accuracy of positioning. A spring 12 is sleeved on the outer side of the adjustment bolt 6 and is located between the lifting adjustment plate 5 and the lifting seat 7. The spring 12 can absorb and buffer the vibrations generated during the test, improving the stability and durability of the special test bench for durability. The function of the spring 12 helps to protect the test bench and its connecting components from excessive vibrations and extends the service life of the equipment. The guide block 13 at the rear side of the lifting adjustment plate 5 cooperates with the guide groove B14 at the bottom of the lifting seat 7 for sliding guidance. The cooperation between the guide block 13 and the guide groove ensures the linear movement of the lifting adjustment plate 5 during the movement, avoiding unnecessary shaking and deviation.

[0031] By turning the locking nut 9, the position of the locking nut 9 on the adjusting bolt 6 is changed, thereby adjusting the height of the lifting and adjusting plate 5 relative to the lifting seat 7, adjusting the installation height of the lifting and adjusting plate 5, and adjusting the installation height of the downward block 4 to adapt to the durability tests of shock absorber cushions with different specifications and heights.

[0032] Through the adjusting bolt 6 and the locking nut 9, the height of the lifting and adjusting plate 5 can be conveniently adjusted, and then the installation height of the downward block 4 can be changed to adapt to the durability tests of shock absorber cushions with different specifications. This design enables the test bench to adapt to various shock absorber cushions with different heights on the market, greatly improving the application range and versatility of the test bench. When it is necessary to replace or adjust the shock absorber cushion, the operator can quickly complete the height adjustment, improving the test efficiency. The design of the vertical guide rail 3 and the guide groove A8 ensures the stable sliding of the lifting seat 7 and guarantees the accuracy of the test process.

[0033] A support platform 16 is fixedly provided on the lower support 15 at the bottom of the bracket 1. A guide seat 17 is fixedly provided on the top of the support platform 16. A linear module 18 is embedded in the guide seat 17. A moving seat 19 that is guided and slides in cooperation with the guide seat 17 is provided on the moving slide of the linear module 18. A test block 20 with a detection sensor is fixedly provided on the top of the moving seat 19.

[0034] The test block 20 is aligned and limited in position with the bottom end of the shock absorber cushion, and the test block 20 is vertically corresponding to the downward block 4.

[0035] The support platform 16 and the lower support 15 provide a solid support foundation for the test bench, ensuring the stability and reliability of the entire test bench. The linear module 18 is embedded in the guide seat 17, providing an accurate movement trajectory for the test bench and guaranteeing precise positioning during the test process. The moving seat 19 on the moving slide can move precisely along the track of the linear module 18 and can move to the loading and unloading station and the test station.

[0036] The detection sensor on the test block 20 can monitor and record key data during the test process in real time, such as force, etc., realizing the automation and digitization of the test. The data collected by the sensor is highly accurate, which helps to evaluate the durability performance of the shock absorber cushion. The sensor can provide real-time feedback on the test results, and the operator can adjust the test conditions in a timely manner to ensure the smooth progress of the test.

[0037] After the test is completed, under the action of the linear module 18, the moving seat 19 is driven to move to the loading and unloading station, and then the position of the test block 20 relative to the downward hydraulic cylinder 11 is staggered, so that when the operator loads and unloads the shock absorber cushion above the test block 20 at the loading and unloading station, it will not be affected by the downward hydraulic cylinder 11, ensuring the safety of the operator.

[0038] The special test bench for the durability of the shock absorber buffer pad can be adjusted in height, enabling the test bench to adapt to shock absorber buffer pads of different specifications, improving the versatility. The hydraulic system and the spring 12 shock absorption design provide a stable test environment, ensuring the accuracy of the test process. The detection sensors on the linear module 18 and the test block 20 achieve the automation and digitization of the test, improving the test efficiency and data accuracy. After the test is completed, the moving seat 19 can safely move the test block 20 to the loading and unloading station, avoiding the potential danger of the downward hydraulic cylinder 11 to the operator during loading and unloading. The design of the spring 12 and the guiding mechanism reduces the wear of the equipment and extends the service life of the equipment. The sensor can feedback the test results in real time, and the operator can adjust the test conditions in time to ensure the smooth progress of the test.

[0039] In summary, the design of this test bench combines precise mechanical structures and automated test technologies, not only improving the accuracy and efficiency of the test, but also ensuring the safety of operation and the durability of the equipment.
