Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen spring elastic force testing, in particular to a detection device used for nitrogen spring elastic force testing. Background Art

[0002] Nitrogen spring is a new type of elastic component that uses high-pressure nitrogen as the working medium. It has higher working performance and wider application fields than conventional elastic components such as metal springs, rubber and air cushions. Elastic force is one of the core performances of nitrogen springs, which is directly related to its effect in practical applications. Therefore, nitrogen springs need to be tested by testing equipment to ensure that the nitrogen springs meet the design requirements, screen out high-quality nitrogen springs, and ensure the stability and reliability of the product.

[0003] Existing testing equipment can only test the elastic force of nitrogen springs one by one, and each nitrogen spring needs to wait for the previous one to be tested before it can be tested.

[0004] For example, the patent publication number CN216645812U discloses an elastic force testing device for nitrogen spring testing. The testing device in this patent has only one testing station. A single testing station may cause a bottleneck in the production process. The nitrogen springs must be tested one by one, and two nitrogen springs cannot be tested at the same time. When a large number of nitrogen spring samples need to be processed, the testing speed will be limited, affecting the overall work efficiency. In this patent, the nitrogen spring is clamped by the first clamp and the second clamp. However, the first clamp and the second clamp can only clamp the left and right sides of the nitrogen spring, and there is no clamping at the front and back ends, resulting in fewer clamping points, which may cause uneven distribution of clamping force, thereby increasing the risk of displacement or deformation of the nitrogen spring during the detection process. This instability may affect the accuracy of the test results.

[0005] Therefore, it is necessary to invent a detection device for nitrogen spring elastic force testing to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a detection device for testing the elastic force of a nitrogen spring, so as to solve the problems of low detection efficiency and insufficient stability in clamping the nitrogen spring in the technology.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a detection device for nitrogen spring elastic force testing, comprising a machine body, an upper pressure plate, a pressure base, a storage platform and a limit plate, a control switch is arranged on the upper side of the machine body, columns are fixedly installed on both sides of the upper side of the machine body, a top beam is fixedly installed on the top of the column, a control panel is arranged on the side wall of the column, Y-axis transmission assemblies are arranged on the left and right sides of the top of the top beam, a lifting plate is arranged below the top beam, a pressure base is arranged above the machine body, a pressure sensor is arranged above the pressure base, a storage platform is arranged above the pressure sensor, a cylinder is arranged on the outer side of the storage platform, and the output end of the cylinder is fixedly connected to the limit plate.

[0008] Preferably, two columns are provided, and the two columns are perpendicular to the machine body, so that the columns can stably support the lifting plate.

[0009] Preferably, two Y-axis transmission assemblies are provided, and the two Y-axis transmission assemblies are centrally symmetrical with respect to the lifting plate, so that the two Y-axis transmission assemblies can improve the stability of the up and down sliding adjustment of the lifting plate.

[0010] Preferably, the lifting plate is arranged between two columns, and the lifting plate is slidably connected to the two columns. The two columns and the lifting plate transmit torque through a Y-axis transmission assembly, so that the Y-axis transmission assembly can drive the lifting plate to be adjusted up and down.

[0011] Preferably, upper pressing plates are provided on both sides below the lifting plate, and two upper pressing plates are provided, so that the upper pressing plates can detect the elastic force of the nitrogen spring when it is pressed downward.

[0012] Preferably, a storage platform is provided directly below the upper pressure plate, and two storage platforms are provided, and the center lines of the storage platforms coincide with the center lines of the upper pressure plate, so that the upper pressure plate can accurately contact and press down with the nitrogen spring inside the storage platform.

[0013] Preferably, the two storage tables are centrally symmetrical with respect to the machine body, so that the two storage tables can perform detection work on two nitrogen springs at the same time, thereby improving the working efficiency of the detection equipment.

[0014] Preferably, the limit plate is designed in an arc-shaped structure, and the limit plate is arranged inside the storage table. The limit plates are distributed in a circular uniform array, so that the limit plate can stably clamp and fix the nitrogen spring, ensuring the reliability and stability of the nitrogen spring during detection.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. Through the arrangement of the upper pressing plate, pressure base, pressure sensor and storage table, since there are two of each of the upper pressing plate, pressure base, pressure sensor and storage table, a double-station detection mode is formed, so that two nitrogen springs can be detected at the same time, avoiding the waiting time that may be generated by a single station, thereby speeding up the detection speed and improving the overall work efficiency;

[0017] 2. Through the setting of the limit plates, the four limit plates can be telescopically adjusted under the action of four cylinders. The four limit plates can more evenly distribute the clamping force on the nitrogen spring, reducing the risk of spring displacement or deformation caused by uneven clamping. The nitrogen spring can be maintained in a more stable state, ensuring that its position during the test is stable and accurate, thereby ensuring the reliability and stability of the test.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-5A detection device for nitrogen spring elastic force testing shown in the figure includes a body 1, an upper pressure plate 8, a pressure base 9, a storage platform 11 and a limit plate 13. A control switch 2 is arranged on the upper side of the body 1, columns 3 are fixedly installed on both sides of the upper side of the body 1, a top beam 4 is fixedly installed on the top of the column 3, a control panel 5 is arranged on the side wall of the column 3, Y-axis transmission assemblies 6 are arranged on the left and right sides of the top of the top beam 4, a lifting plate 7 is arranged below the top beam 4, a pressure base 9 is arranged above the body 1, a pressure sensor 10 is arranged above the pressure base 9, a storage platform 11 is arranged above the pressure sensor 10, a cylinder 12 is arranged on the outer side of the storage platform 11, and the output end of the cylinder 12 is fixedly connected to the limit plate 13.

[0027] In one aspect of the present embodiment, there are two columns 3, and the two columns 3 are perpendicular to the body 1. There are two Y-axis transmission assemblies 6, and the two Y-axis transmission assemblies 6 are centrally symmetrical with respect to the lifting plate 7. The lifting plate 7 is arranged between the two columns 3, and the lifting plate 7 is slidably connected to the two columns 3. The two columns 3 and the lifting plate 7 transmit torque through the Y-axis transmission assembly 6. Upper pressing plates 8 are arranged on both sides below the lifting plate 7. There are two upper pressing plates 8. A storage platform 11 is arranged directly below the upper pressing plate 8. There are two storage platforms 11. The center line of the storage platform 11 coincides with the center line of the upper pressing plate 8. The two storage platforms 11 are centrally symmetrical with respect to the body 1. The limit plate 13 is designed with an arc-shaped structure. The limit plate 13 is arranged inside the storage platform 11, and the limit plates 13 are distributed in a circular uniform array.

[0028] The two storage tables 11 can be used to test two nitrogen springs at the same time, which can significantly reduce the testing time of a single spring. The two testing tables work in parallel to increase the testing capacity, so that more springs can be tested at the same time to meet the requirements of large-scale production. The limit plates 13 can be set to evenly clamp and fix the nitrogen springs on all sides, which can ensure that the nitrogen springs maintain a stable posture during testing or working, which helps to reduce measurement errors caused by shaking or movement of the nitrogen springs and improve the accuracy of testing.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual Figure 1-5When using the utility model, first place the detection device stably at a suitable position, and connect the power supply of the detection device to the external power supply so that the detection device is in a powered-on and operable state, and then place the two nitrogen springs to be detected inside the two storage tables 11 respectively. When the nitrogen spring is placed inside the storage table 11, the four cylinders 12 drive the four limit plates 13 to evenly clamp the four sides of the nitrogen spring, thereby ensuring that the nitrogen spring can be maintained in a more stable state inside the storage table 11. Then the control switch 2 can be started so that the lifting plate 7 can drive the two upper pressing plates 8 to descend at the same time under the action of the two Y-axis transmission assemblies 6, so that the upper pressing plate 8 can forcefully press the two clamped nitrogen springs, thereby simultaneously performing the detection of the two nitrogen springs. At this time, the pressure sensor 10 can sense and measure the pressure applied by the upper pressing plate 8 to the nitrogen spring in real time, and it can accurately convert this pressure change into an electrical signal or other form of output, and transmit it to the control panel 5 for display, so as to facilitate subsequent processing, and then evaluate whether its performance meets the requirements.
