Description

Technical Field

[0001] The utility model belongs to the technical field of elastic detection of spring washers, and particularly relates to a spring washer elasticity experiment fixture. Background Art

[0002] As one of the key components for the assembly of high-strength, tough and weather-resistant bolts, a spring washer (also known as a spring washer) needs to provide necessary pre-tightening force to maintain the reliability and anti-loosening function of the bolt connection. To ensure that the spring washer can meet the high-standard requirements for the assembly and fastening of high-strength, tough and weather-resistant bolts, strict performance testing of it is an indispensable part. Traditional elasticity experiment fixtures mainly focus on applying a preset load and observing the macroscopic response of the spring washer, such as the degree of deformation, recovery ability, etc., but often lack direct and accurate measurement of the displacement change during the compression process of the spring washer. The main disadvantages of the commonly existing elasticity experiment fixtures in the market are as follows:

[0003] 1. Insufficient data accuracy: Due to the lack of integration of displacement sensors, the existing experiment fixtures cannot monitor the displacement change of the spring washer during compression in real time and accurately, and only rely on external observation or rough estimation by auxiliary tools, which greatly reduces the accuracy of the experimental data and is difficult to meet the requirements of high-precision measurement.

[0004] 2. Low experiment efficiency: The lack of automatic data acquisition ability means that experimenters need to manually record displacement data, which is not only time-consuming and laborious, but also prone to introducing human errors, reducing the overall efficiency of the experiment.

[0005] 3. Limited mechanical property analysis: The fixture without displacement detection function makes it difficult for researchers to directly obtain the stress-strain curve of the spring washer, thereby affecting the in-depth analysis and accurate calculation of key mechanical property indexes such as elastic modulus and yield strength, and restricting the comprehensive understanding and optimization of the material properties of the spring washer.

[0006] In view of the above deficiencies, it is particularly urgent to develop a spring washer elasticity experiment fixture integrated with a displacement sensor, aiming to improve the reliability of experimental data and the experiment efficiency through real-time and accurate displacement monitoring, and provide a more scientific and efficient experimental means for the in-depth research, performance optimization and new product development of spring washer materials. Content of the Utility Model

[0007] In order to solve the above technical problems, the utility model is solved by the following technical solutions.

[0008] A spring washer elasticity experiment fixture, comprising a base and a pressing plate. A placement area for placing the spring washer is provided on the base, and the pressing plate is located above the placement area. A displacement sensor is assembled inside the base, and a through hole for the detection end of the displacement sensor to pass through is provided on the placement area. Compared with the traditional experiment fixture without displacement detection function, the utility model realizes the accurate measurement of the displacement change during the compression process of the spring washer by integrating the displacement sensor, significantly improving the accuracy of experimental data and experimental efficiency. This design can not only monitor the elastic deformation of the spring washer in real time, but also further analyze key mechanical property indexes such as the elastic modulus and yield strength of the spring washer, providing a scientific basis for the research and development, quality control and product optimization of spring washer materials.

[0009] Preferably, a support plate is assembled on the base through a positioning pin, and the placement area is located on the support plate. This design can conveniently replace the support plate when it is damaged, ensuring that the continuity and accuracy of the experiment are not affected, and enhancing the stability and service life of the fixture.

[0010] Preferably, a placement groove for placing the displacement sensor is provided on the base, and a fixing hole is provided on one side of the placement groove. The fixing hole is used to assemble a fastener to fixedly connect the displacement sensor with the base.

[0011] Preferably, a wire outlet groove is provided below the placement groove on the base, facilitating the wire outlet of the displacement sensor, allowing the wires to droop naturally and be managed orderly, reducing the risk of wire entanglement and extrusion.

[0012] Preferably, the wire outlet groove penetrates through the base. This design can facilitate the staff to adjust the wire outlet position of the displacement sensor to optimize the wiring layout, improving the overall cleanliness and maintenance efficiency of the system.

[0013] Preferably, the ratio of the length of the wire outlet groove to the height of the base is greater than 1 / 2, ensuring that the wiring of the displacement sensor has a sufficient bending radius, avoiding damage to the wires due to excessive bending inside the base, and also facilitating wire management and maintenance by users.

[0014] Preferably, a limiting boss is provided on the placement area. The diameter of the limiting boss is smaller than the inner diameter of the tested spring washer, and the through hole is located at the center of the limiting boss. The design of the limiting boss can effectively prevent the spring washer from shifting or rolling during compression, ensuring that the detection end of the displacement sensor is always aligned with the center of the spring washer and guaranteeing the accuracy of the measurement data.

[0015] Compared with the prior art, the utility model has the following beneficial effects: integrating a displacement sensor, capable of accurately measuring the displacement change during the compression process of the spring washer, and helping the staff to further analyze key mechanical property indexes such as the elastic modulus and yield strength of the spring washer.
