[0002] A suspension tension and compression testing device typically refers to specialized equipment used for tensile and compressive testing of elastic components (such as springs) in automotive suspension systems. This device is widely used in numerous industries, including machinery manufacturing, automotive, and aerospace. Particularly in the automotive industry, this device is crucial for ensuring the quality and performance of suspension systems. Through testing, performance indicators such as tensile strength, elastic limit, and elongation of suspension springs, as well as key parameters such as fatigue life and reliability, can be evaluated. However, existing technologies have the following limitations:

[0003] Existing elastic suspension tension and compression testing devices, without pressure compensation clamping components, can only use fixed clamps or simple clamping methods, making it impossible to adjust the clamping force in real time. This may result in the elastic suspension being loosened due to insufficient clamping during the test, or excessive clamping force causing excessive compression damage to the elastic suspension. In addition, existing devices cannot precisely control and adjust the applied tension or compression, and cannot apply different levels of force to the elastic suspension according to different test requirements, resulting in poor accuracy of test results.

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0022] like Figure 1 , Figure 2As shown, this utility model provides a tension and compression testing device for an elastic suspension, including a base 10. A fixed seat 11 is fixedly connected to the top left side of the base 10. A central controller 12 is fixedly connected to the rear side wall of the fixed seat 11. Two side plates 15 are fixedly connected to the top of the base 10. Two symmetrical sliding rods 13 are fixedly connected to the opposite surfaces of the left and right side plates 15. A movable slide block 16 is slidably connected to the outer wall of the two sliding rods 13. A fixed frame 14 is fixedly connected to the top of both the fixed seat 11 and the movable slide block 16. A pressure compensation clamping assembly 2 is provided inside the two fixed frames 14. A testing assembly 3 is provided on the top right side of the base 10.

[0023] The base 10 is the basic support component of the entire device. The central controller 12 is fixedly connected to the rear side wall of the fixed seat 11. The central controller 12 plays a core control and coordination role in the entire testing process. It is responsible for receiving signals from different sensors and controlling and adjusting components such as the motor 25 and the tensile testing machine 30. Two symmetrical sliding rods 13 are fixedly connected to the opposite surfaces of the left and right side plates 15. The sliding rods 13 provide a sliding track for the movable slide block 16, so that the movable slide block 16 can slide smoothly back and forth along the sliding rods 13.

[0024] like Figure 3 , Figure 4 As shown, the pressure compensation clamping assembly 2 includes a pressure sensor 20, which is fixedly connected to the inner bottom wall of the fixed frame 14. A fixing block 21 is fixedly connected to the inner top wall of the fixed frame 14. Two symmetrical connecting rods 22 are rotatably connected to the bottom of the fixing block 21. A connecting block 23 is rotatably connected to the end of the rear connecting rod 22 away from the fixing block 21, and a threaded block 24 is rotatably connected to the end of the front connecting rod 22 away from the fixing block 21.

[0025] like Figure 3 , Figure 4 As shown, a motor 25 is fixedly connected to the rear side wall of the connecting block 23. The output end of the motor 25 passes through to the front side wall of the connecting block 23 and is fixedly connected to a screw 26. The outer wall of the screw 26 is threadedly connected to the threaded block 24. The front end of the screw 26 passes through to the front side wall of the threaded block 24 and is fixedly connected to a limit block 27. The bottom of both the connecting block 23 and the threaded block 24 are rotatably connected to connecting rods 28. The two connecting rods 28 are symmetrically arranged front and back and are rotatably connected to a fixing block 29 at their ends. The two connecting rods 22 and the two connecting rods 28 form a parallelogram structure. The bottom of the fixing block 29 is fixedly connected to a fixing extrusion plate 290.

[0026] like Figure 3 , Figure 4 As shown, the central controller 12 is electrically connected to the motor 25 and the pressure sensor 20, respectively.

[0027] When it is necessary to clamp and fix the elastic suspension, firstly, place both ends of the elastic suspension between the pressure compensation clamping assembly 2 on the fixed seat 11 and the movable slide 16. Then, start the motor 25 through the central controller 12. When the motor 25 starts, the outer wall of the output shaft of the motor 25 is rotatably connected to the connecting block 23, and drives the screw 26 fixedly connected to its output end to rotate. Due to the threaded connection between the screw 26 and the threaded block 24, the threaded block 24 will move along the axial direction of the screw 26. The bottom of both the connecting block 23 and the threaded block 24 are rotatably connected to the connecting rod 28. The ends of the two connecting rods 28 that are close to each other are rotatably connected to the fixed block 29. The connecting rod 22 and the connecting rod 28 form a parallelogram structure. As the threaded block 24 moves, due to the characteristics of the parallelogram structure, it will drive the fixed block 29 and the threaded block 24 to rotate. The fixed extrusion plate 290 at the bottom moves up and down, applying pressure to the elastic suspension and clamping it. During this process, the pressure sensor 20 on the bottom wall of the fixed frame 14 monitors the pressure in real time and transmits the pressure signal to the central controller 12. The central controller 12 adjusts the position of the threaded block 24 by controlling the speed and direction of rotation of the motor 25 according to the pressure signal, thereby achieving pressure compensation for the elastic suspension. Through the pressure compensation clamping component 2, the pressure can be adjusted according to the pressure signal fed back by the pressure sensor 20 to ensure that the clamping force on the elastic suspension is within a suitable range, avoiding loosening due to insufficient clamping force, and also avoiding local deformation or damage to the elastic suspension due to excessive extrusion, thereby improving the reliability of the test data.

[0028] like Figure 5 As shown, the test assembly 3 includes a tensile testing machine 30, which is fixedly connected to the top right side of the base 10. A displacement sensor 31 is fixedly connected to the left side wall of the movable slide 16, and a pull ring 32 is fixedly connected to the right side wall of the movable slide 16. Two symmetrical side plates 34 are fixedly connected to the top right side of the base 10. Rollers 35 are rotatably connected to the opposite surfaces of the two side plates 34. A traction rope 33 is fixedly connected to the inner wall of the pull ring 32. The right end of the traction rope 33 passes around the roller 35 and is fixedly connected to the traction component of the tensile testing machine 30.

[0029] like Figure 5 As shown, the central controller 12 is electrically connected to the displacement sensor 31 and the tensile testing machine 30, respectively.

[0030] When the tensile and compressive test begins, the tensile testing machine 30 is started. The tensile testing machine 30 pulls the traction rope 33, which drives the pull ring 32, thereby pulling the movable slide 16. Since the movable slide 16 is slidably connected between the side plates 15 via the slide rod 13, the movable slide 16 will move along the slide rod 13. At the same time, the displacement sensor 31 on the left side wall of the movable slide 16 will monitor the displacement of the movable slide 16 in real time and transmit the displacement signal to the central controller 12. In addition, the tensile testing machine 30 itself will also transmit the tensile force data it applies to the central controller 12. During the tensile and compressive test, the tensile testing machine 30 can apply different magnitudes of tensile force according to different test requirements, and test the elasticity. During the tensile test of the elastic component suspension, the central controller 12 can receive signals from the pressure sensor 20, displacement sensor 31, and tensile testing machine 30. According to the preset program and test requirements, it controls the motor 25 and tensile testing machine 30 to coordinate the entire test process. Through the set test components 3, the device can accurately control and adjust the applied tensile or compressive force to meet different test requirements. This enables accurate testing and data recording of the tensile and compressive performance of the elastic component suspension, thereby accurately evaluating the performance of the elastic component suspension under different tensile and compressive conditions. This allows for in-depth analysis and comparison of the data, providing rich historical data for subsequent research and improvement.

[0031] It should be noted that the central controller 12 is model S7-200SMART, the displacement sensor 31 can be a linear displacement sensor, such as the MTSR series magnetostrictive displacement sensor, the tensile testing machine 30 includes drive components and traction components, and can be a microcomputer-controlled electronic universal testing machine, such as model MTSE43.105, and the pressure sensor 20 can be a piezoresistive pressure sensor, such as MPS20N0040D-S. All of the above components are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.

[0032] The working principle of this elastic component suspension tension and compression testing device will be explained in detail below.

[0033] like Figure 1-5As shown, when it is necessary to clamp and fix the elastic suspension, firstly, place both ends of the elastic suspension between the pressure compensation clamping assembly 2 on the fixed seat 11 and the movable slide 16. Then, start the motor 25 through the central controller 12. When the motor 25 starts, the outer wall of the output shaft of the motor 25 is rotatably connected to the connecting block 23, and drives the screw 26 fixedly connected to its output end to rotate. Due to the threaded connection between the screw 26 and the threaded block 24, the threaded block 24 will move along the axial direction of the screw 26. The bottom of the connecting block 23 and the threaded block 24 are rotatably connected to the connecting rod 28. The ends of the two connecting rods 28 that are close to each other are rotatably connected to the fixed block 29. The connecting rod 22 and the connecting rod 28 form a parallelogram structure. As the threaded block 24 moves, due to the characteristics of the parallelogram structure, it will drive the fixed block 29. The fixed extrusion plate 290 at its bottom moves up and down, applying pressure to the elastic suspension and clamping it. During this process, the pressure sensor 20 on the bottom wall of the fixed frame 14 monitors the pressure in real time and transmits the pressure signal to the central controller 12. The central controller 12 adjusts the position of the threaded block 24 by controlling the speed and direction of rotation of the motor 25 according to the pressure signal, thereby achieving pressure compensation for the elastic suspension. Through the pressure compensation clamping component 2, the pressure can be adjusted according to the pressure signal fed back by the pressure sensor 20 to ensure that the clamping force on the elastic suspension is within a suitable range, avoiding loosening due to insufficient clamping force, and also avoiding local deformation or damage to the elastic suspension due to excessive extrusion, thereby improving the reliability of the test data.

[0034] When the tensile and compressive test begins, the tensile testing machine 30 is started. The tensile testing machine 30 pulls the traction rope 33, which drives the pull ring 32, thereby pulling the movable slide 16. Since the movable slide 16 is slidably connected between the side plates 15 via the slide rod 13, the movable slide 16 will move along the slide rod 13. At the same time, the displacement sensor 31 on the left side wall of the movable slide 16 will monitor the displacement of the movable slide 16 in real time and transmit the displacement signal to the central controller 12. In addition, the tensile testing machine 30 itself will also transmit the tensile force data it applies to the central controller 12. During the tensile and compressive test, the tensile testing machine 30 can apply different magnitudes of tensile force according to different test requirements, and test the elasticity. During the tensile test of the elastic component suspension, the central controller 12 can receive signals from the pressure sensor 20, displacement sensor 31, and tensile testing machine 30. According to the preset program and test requirements, it controls the motor 25 and tensile testing machine 30 to coordinate the entire test process. Through the set test components 3, the device can accurately control and adjust the applied tensile or compressive force to meet different test requirements. This enables accurate testing and data recording of the tensile and compressive performance of the elastic component suspension, thereby accurately evaluating the performance of the elastic component suspension under different tensile and compressive conditions. This allows for in-depth analysis and comparison of the data, providing rich historical data for subsequent research and improvement.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
