[0006] Compared with the prior art, the beneficial effects of the utility model are:
[0007] The vehicle gas spring comprehensive test bench realizes the precise adjustment of the distance between the upper clamping plate and the lower clamping plate by sliding the movable rod in the groove of the fixed block, combined with the drive of the drive motor and the external threaded rotating rod. This design enables the test bench to flexibly adapt to gas springs of different sizes. Whether large or small, the gas springs can be stably and reliably clamped, thereby avoiding the test error caused by improper clamping.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] See also Figure 1-6 The utility model provides a technical solution: a comprehensive test bench for vehicle gas springs, comprising a comprehensive test bench body 1, a movable plate 2 is slidably connected to the top position of the front surface of the comprehensive test bench body 1, and a bottom end plate 3 is fixedly connected to the bottom position of the front surface of the comprehensive test bench body 1, and a plurality of fixed blocks 4 are fixedly connected to the front sides of the movable plate 2 and the bottom end plate 3. The two fixed blocks 4 arranged on the left and right are symmetrically arranged, and movable rods 5 are arranged on opposite sides of the two fixed blocks 4. The opposite sides of the two movable rods 5 arranged at the top are fixedly connected to the upper clamping plate 6, and the opposite sides of the two movable rods 5 arranged at the bottom are fixedly connected to the lower clamping plate 17. A groove 11 is provided inside the fixed block 4, and the opposite sides of the two movable rods 5 respectively penetrate into the inside of the two grooves 11 and are slidably connected to the grooves 11. An internal thread groove 14 is provided at the center of one side of the movable rod 5, and a driving motor 15 is fixedly installed on the opposite sides of the two fixed blocks 4, and an external threaded rotating rod 16 is fixedly connected to the output end of one side of the driving motor 15.
[0017] The inner wall of the upper clamping plate 6 and the inner wall of the lower clamping plate 17 are both fixedly connected with a sponge pad 7 near the top, and one side of the sponge pad 7 is fixedly connected with a pressing plate 8 .
[0018] A slider 13 is fixedly connected to one side of the top and bottom of the movable rod 5, and a slide groove 12 is provided at the top and bottom of the corresponding groove 11 inside the fixed block 4. The side of the slider 13 away from the movable rod 5 penetrates into the interior of the slide groove 12 and is slidably connected to the slide groove 12, which increases the stability of the movable rod 5 during movement, prevents the movable rod 5 from deflecting or shaking during sliding, and ensures the accuracy and reliability of the clamping process.
[0019] One side of the external threaded rotating rod 16 penetrates into the interior of the internal threaded groove 14 and is threadedly connected to the internal threaded groove 14. This design allows precise control of the moving distance of the movable rod 5, thereby achieving precise clamping and release of the tested gas spring.
[0020] The inner wall of the pressure plate 8 is fixedly connected with a plurality of anti-skid balls 9, which increases the friction force of the contact surface with the tested gas spring, effectively prevents the gas spring from sliding or falling off during the test, and improves the accuracy and safety of the test.
[0021] The front surfaces of the movable plate 2 and the bottom end plate 3 are provided with movable grooves 19 corresponding to the rear sides of the movable rod 5. The rear sides of the movable rod 5 are fixedly connected with a support plate 18. The rear sides of the support plate 18 penetrate into the interior of the movable groove 19 and are slidably connected with the movable groove 19, providing additional support and guidance for the movable rod 5, making the movable rod 5 more stable during the movement, thereby further improving the accuracy of the test.
[0022] The sponge pad 7 is internally fixedly connected to the limiting block 10, which ensures the shape stability of the sponge pad 7 during the force-bearing process, avoids excessive pressure or damage to the gas spring, and improves the reliability and safety of the test.
[0023] Working principle: The operator places the vehicle gas spring to be tested between the upper clamping plate 6 and the lower clamping plate 17, prepares for clamping, and starts the driving motor 15. The output end of the driving motor 15 drives the external threaded rotating rod 16 to start rotating. Since the external threaded rotating rod 16 is threadedly connected with the internal thread groove 14 on the movable rod 5, the rotation of the external threaded rotating rod 16 will drive the movable rod 5 to slide in the groove 11 of the fixed block 4. As the movable rod 5 slides, the upper clamping plate 6 and the lower clamping plate 17 gradually move toward the middle, gradually approaching and clamping the gas spring. During this process, the sliders 13 at the top and bottom of the movable rod 5 slide in the slide groove 12 of the fixed block 4, which increases the stability of the movable rod 5 during movement and prevents deviation or shaking. At the same time, the support plate 18 on the rear side of the movable rod 5 slides in the movable groove 19, providing additional support and guidance for the movable rod 5, further enhancing the stability. 6 and the lower clamping plate 17 completely clamp the gas spring, the driving motor 15 stops working. At this time, the gas spring is stably clamped on the test bench and is ready for testing. During the test, the anti-slip balls 9 on the inner wall of the pressure plate 8 increase the friction with the contact surface with the tested gas spring, effectively preventing the gas spring from sliding or falling off. The sponge pad 7 provides a soft clamping environment for the gas spring. At the same time, the limit block 10 inside it ensures the shape stability of the sponge pad 7 during the force-bearing process, avoiding excessive compression or damage to the gas spring. After the test is completed, the driving motor 15 is started again, but its rotation direction is changed to make the externally threaded rotating rod 16 rotate in the opposite direction. Driven by the reversely rotating externally threaded rotating rod 16, the movable rod 5 slides outward along the groove 11, driving the upper clamping plate 6 and the lower clamping plate 17 to gradually separate, releasing the gas spring. The operator takes out the tested gas spring, cleans the test bench, and prepares for the next test.
[0024] In summary: the vehicle gas spring comprehensive test bench realizes the precise adjustment of the distance between the upper clamping plate 6 and the lower clamping plate 17 by sliding the movable rod 5 in the groove 11 of the fixed block 4, combined with the drive of the driving motor 15 and the external threaded rotating rod 16. This design enables the test bench to flexibly adapt to gas springs of different sizes. Whether large or small, the gas springs can be stably and reliably clamped, thereby avoiding test errors caused by improper clamping. By arranging a slider 13 on the movable rod 5 to be slidably connected with the slide groove 12 of the fixed block 4, the stability of the movable rod 5 during movement is greatly enhanced. At the same time, the movable groove 19 on the movable plate 2 and the bottom end plate 3 is connected to the movable plate 2. The cooperation of the support plate 18 provides additional support and guidance for the movable rod 5, further improving the stability and reliability of the clamping process. This design ensures that the gas spring will not shake or fall off during the test, thereby improving the accuracy and safety of the test. The anti-slip ball 9 design on the inner wall of the pressure plate 8 effectively increases the friction with the contact surface of the tested gas spring, preventing the gas spring from sliding or falling off during the test, and the limit block 10 inside the sponge pad 7 ensures the shape stability of the sponge pad 7 during the force process, avoiding excessive compression or damage to the gas spring. This design not only improves the accuracy of the test, but also protects the integrity of the gas spring and extends its service life.
