Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a mounting platform for a push-pull testing device. Background Technology

[0002] In modern industrial production, product quality control and performance testing are crucial for ensuring product consistency and reliability. Especially in fields such as precision manufacturing and electronic assembly, push-pull force testing is widely used as an important means of evaluating the connection strength, durability, and assembly stability of components.

[0003] Existing push-pull testing systems typically consist of a push-pull force machine, a loading platform, and sensors. The push-pull force machine generates axial load, while the sensors collect force change signals. Together, they are used to analyze the mechanical properties of the workpiece under test. However, these components in existing technologies are mostly separate structures, meaning that the push-pull force output device and the force acquisition device are independently deployed, lacking a unified structural platform or linkage control mechanism. This structural arrangement not only increases the complexity of system integration but also hinders efficient and synchronous test execution, especially in automated testing scenarios where there are significant limitations.

[0004] Furthermore, most push-pull testing devices widely used in the market employ a combination structure of guide rails and sliders for their displacement platforms. While this type of structure possesses a certain load-bearing capacity and adjustable stroke, it is prone to vertical or lateral loosening during actual operation due to the limited clearance between the guide rails and sliders. This mechanical looseness can cause slight swaying of the platform when push-pull forces are applied, resulting in warping, displacement, or non-axial shift of the workpiece under test during loading. This, in turn, affects the accuracy of the sensor's force value acquisition, leading to large fluctuations in test data and poor measurement repeatability.

[0005] Therefore, a mounting platform for a push-pull testing device is proposed to solve the above problems. Utility Model Content

[0006] The main purpose of this utility model is to provide a mounting platform for a push-pull testing device, which aims to solve the problem that the displacement platform of the existing push-pull testing device has mechanical misalignment, which causes the workpiece under test to warp during loading, affecting the acquisition of measurement values ​​and reducing measurement accuracy.

[0012] The upper surface of the slider is connected to the testing device, and the driving mechanism is used to drive the lead screw so that the slider slides along the lead screw.

[0013] Furthermore, it also includes an optical axis and a guide sleeve, the guide sleeve being slidably mounted on the optical axis, the two ends of the optical axis being fixedly mounted on the inner wall of the mounting cavity, the guide sleeve being flush with the slider and configured for mounting the testing device.

[0014] Furthermore, the testing device is positioned along the X direction of the guide sleeve and the slider.

[0015] Furthermore, the testing device is positioned along the Y direction of the guide sleeve and the slider.

[0016] Furthermore, there are two optical axes, which are respectively located on both sides of the lead screw.

[0017] Furthermore, the optical axis and the guide sleeve correspond one-to-one.

[0018] Furthermore, there is a gap between the guide sleeve and the slider.

[0019] Furthermore, it also includes an elastic element, with its two ends connected to the output shaft and lead screw of the drive mechanism, respectively, and is configured for buffering and shock absorption.

[0020] Furthermore, the elastic element is a metallic elastomer.

[0040] Reference Figures 1 to 3 An embodiment of this utility model provides a mounting platform for a push-pull testing device, comprising:

[0041] The base 100 has an installation cavity 110;

[0042] A drive mechanism 200 is disposed on the base 100, and the output shaft passes through the base 100;

[0043] A lead screw 300 is disposed in the mounting cavity 110 and connected to the output shaft of the drive mechanism 200;

[0044] The slider 400 is slidably mounted on the lead screw 300, and its upper surface is flush with the opening of the mounting cavity 110;

[0045] The upper surface of the slider 400 is connected to the testing device, and the driving mechanism 200 is used to drive the lead screw 300 so that the slider 400 slides along the lead screw 300.

[0046] The drive mechanism 200 is a servo motor.

[0047] This X-axis platform includes an integrated base 100, a drive mechanism 200, a lead screw 300, and a slider 400. A servo motor serves as the drive mechanism 200, with its output shaft passing through the base 100 and directly connected to the lead screw 300. The rotation of the servo motor drives the lead screw 300 to rotate, which in turn causes the slider 400 to slide axially, achieving linear forward or backward movement of the testing device. The upper surface of the slider 400 is flush with the opening of the mounting cavity 110, allowing for the installation of upper-level testing devices. The sliding motion enables testing actions. Precise control of the servo motor allows for accurate adjustment of the slider 400's displacement and speed, meeting the requirements of different push-pull force tests. In this embodiment, a servo motor drives the lead screw 300, enabling high-precision control of the slider 400's displacement and meeting the dual requirements of response speed and positioning accuracy in push-pull tests. Furthermore, the servo motor used in this solution is a servo A6 series motor.

[0048] The mounting platform for the push-pull testing device also includes an optical axis 500 and a guide sleeve 600. The guide sleeve 600 is slidably mounted on the optical axis 500. Both ends of the optical axis 500 are respectively fixedly mounted on the inner wall of the mounting cavity 110. The guide sleeve 600 is flush with the slider 400 and is configured for mounting the testing device.

[0049] The number of optical axes 500 is two, and the two optical axes 500 are respectively disposed on both sides of the lead screw 300;

[0050] The optical axis 500 and the guide sleeve 600 are in one-to-one correspondence;

[0051] There is a gap between the guide sleeve 600 and the slider 400.

[0052] Based on the above embodiments, in order to further improve the guiding accuracy and structural stability of the slider 400 during operation, this embodiment also includes a guiding structure, specifically including an optical axis 500 and a guide sleeve 600.

[0053] Two optical axes 500 are arranged parallel to each other along the X-axis and located on both sides of the lead screw 300. Their two ends are fixedly installed on the opposite inner walls of the mounting cavity 110 of the base 100, forming a stable double guide rail support structure. The guide sleeves 600 are arranged one-to-one with the optical axes 500 and can be slidably sleeved on the corresponding optical axes 500. Each guide sleeve 600 is arranged on both sides of the slider 400 and is flush with the slider 400 in the axial position.

[0054] To balance the assembly precision of the slider 400 with the operational stability of the guiding system, a small gap is designed between the guide sleeve 600 and the slider 400. This gap ensures smooth sliding of the guide sleeve 600 on the optical axis 500 and effectively isolates the influence of stress or slight shaft misalignment generated during the drive of the lead screw 300 on the guiding fit precision of the guide sleeve 600-optical axis 500, thus avoiding jamming or uneven wear of the guiding mechanism due to coupling interference. The above structure forms a composite transmission mode of "helical drive of the lead screw 300 and linear guidance of the optical axis 500". As the slider 400 moves along the axial direction of the lead screw 300, the guide sleeve 600 slides synchronously on the optical axis 500, providing precise position guidance and support for the slider 400. This structure not only improves the overall guiding precision of the platform and the linearity of the slider 400's movement, but also exhibits excellent dynamic stability and anti-displacement capability when the slider 400 load-bearing testing device performs high-frequency or high-load push-pull tests.

[0055] In particular, by setting two optical axes 500 that correspond one-to-one with the guide sleeves 600, a double constraint is formed on the slider 400, which effectively improves the structural rigidity and symmetrical balance of the entire platform in the working state, making it less likely for the test device to wobble or tilt during loading, thereby improving the accuracy and repeatability of push-pull force measurement.

[0056] Based on the above embodiments, the testing device is arranged along the X direction of the guide sleeve 600 and the slider 400;

[0057] The testing device is arranged along the Y direction of the guide sleeve 600 and the slider 400.

[0058] In this embodiment, the testing device can be flexibly set along the X or Y direction of the slider 400 and the guide sleeve 600 according to actual testing needs, so as to adapt to workpiece inspection tasks in different directions. This design fully considers the realities of the changing positions of test objects and the diverse space constraints in industrial sites, thereby achieving a high degree of versatility and adaptability of platform structure and testing functions.

[0059] When the testing device is set along the X direction, its force application direction is consistent with the push-pull drive direction of the platform, and it can directly perform forward push-pull tests on the workpiece located in front of the platform, which is suitable for conventional linear loading test scenarios. When the testing device is set along the Y direction, although its body is perpendicular to the movement direction of the lead screw, the slider 400 and the guide sleeve 600 form a stable mounting surface in the middle of the platform, so the test force can still be accurately transmitted to the workpiece to be tested on one side of the platform through the lateral extension structure, realizing lateral loading test. This Y-direction arrangement is suitable for situations where the position of the workpiece body is limited and it is not possible to directly connect with the testing device, thus improving the platform's adaptability in complex testing environments.

[0060] The key advantage of this solution is that the working direction of the testing device can be adjusted independently of the platform structure. Users do not need to change the installation direction of the platform body or rearrange the platform axis. They only need to rotate or reposition the testing device according to the testing requirements to quickly switch between the X and Y directions, which greatly improves testing efficiency and equipment versatility. Especially on automated testing lines with multiple stations, multiple directions, and multiple batches, this solution avoids frequent disassembly and alignment operations, reduces the intensity of manual intervention, and also reduces the risk of errors.

[0061] In summary, by allowing the testing device to be flexibly arranged along the X or Y direction within the plane of slider 400 and guide sleeve 600, this embodiment significantly improves the platform's usability and directional compatibility, meeting the needs of diverse testing tasks. High-precision push-pull tests on workpieces in front or on the side can be completed without adjusting the platform itself, reducing the intensity of manual intervention.

[0062] The mounting platform for the push-pull testing device also includes an elastic element 700, with its two ends connected to the output shaft of the drive mechanism 200 and the lead screw 300, respectively, and is configured for buffering and shock absorption.

[0063] The elastic element 700 is a metallic elastomer.

[0064] This embodiment, through the cooperation of the dual optical axis 500 guiding structure and the slider 400, effectively enhances the stability and anti-deviation capability of the slider 400 during movement, and improves the load-bearing capacity, guiding accuracy, and test repeatability of the entire platform. The elastic element 700 is preferably an elastic coupling, one end of which is fixedly connected to the output shaft of the servo motor, and the other end is fixedly connected to the input end of the lead screw 300. This coupling can be a metal diaphragm coupling, a plum blossom coupling, or an elastic sleeve coupling, which has good torque transmission capability and elastic compensation performance. In actual use, when the servo motor starts and stops at high speed or reverses rapidly, its output shaft will generate a certain instantaneous impact force or angular acceleration fluctuation. At this time, the elastic coupling set between the motor and the lead screw 300 can effectively absorb the impact load in the transmission process, reduce the mechanical stress transmission between the shafts, make the testing device more stable during the detection process, and improve the measurement accuracy.

[0065] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
