Description

TECHNICAL FIELD

[0001] The utility model belongs to new energy automobile bearing processing technical field especially relates to a kind of performance testing device of new energy automobile bearing processing. BACKGROUND

[0002] The bearing material performance tester for new energy automobile bearing processing is a precision instrument for detecting and evaluating the physical and chemical properties of bearing materials. It can measure the hardness, strength, toughness, fatigue life, wear resistance and corrosion resistance of materials, and ensure that the bearing materials meet the high performance requirements of new energy vehicles. Through these tests, the reliability and durability of bearings under extreme working conditions can be guaranteed, thereby improving the overall performance and safety of new energy vehicles. In the new energy vehicle industry, the selection and performance testing of bearing materials are crucial. These testers usually combine advanced sensing technology, automated control systems and data analysis software to provide accurate, reliable and efficient test results. Specifically, the new energy automobile bearing material performance tester is used to apply a predetermined load to the bearing material to simulate the stress conditions in actual work. This system can accurately control the loading speed, loading direction and maximum load amount to ensure the accuracy and repeatability of the test. These sensors are used to capture various physical responses of the bearing material during the stress process, such as displacement, deformation, vibration, etc. These data are important basis for evaluating material performance. The system is responsible for collecting data from sensors and performing real-time or offline analysis. Through advanced data processing algorithms, key performance indicators can be extracted and detailed test reports can be generated. In order to more realistically simulate the working environment of new energy vehicles, the tester may also be equipped with environmental simulation devices. These devices can adjust temperature, humidity, pressure and other environmental parameters to evaluate the performance of bearing materials under different conditions. When performing high-performance tests, the safety of operators must be ensured. Therefore, the tester is usually equipped with various safety protection devices, such as emergency stop button, overload protection device, etc. In summary, the new energy automobile bearing material performance tester is an indispensable important equipment in the manufacturing process of new energy vehicles. By accurately testing various performance indicators of bearing materials, it can ensure that the bearing quality of new energy vehicles meets the design requirements, thereby improving the overall performance and reliability of new energy vehicles.

[0003] The bearing material performance tester for new energy vehicle bearing machining is used to evaluate and ensure that the physical and chemical properties of the bearing material meet certain standards. It can measure the hardness, strength, toughness, fatigue life, corrosion resistance and other key parameters of the material, so as to ensure the reliability and durability of the bearing in new energy vehicles. Hardness is a physical quantity that measures the ability of a material to resist local pressure and deform. By testing the hardness of the bearing material, its wear resistance and fatigue resistance can be evaluated, which is crucial for the long-term stability of the bearing under high-speed operation and high-load conditions. Strength tests include tensile strength, compressive strength, etc. These tests help determine the maximum stress value that the material can withstand when subjected to external forces. High-strength materials can better resist fracture and deformation, thereby improving the safety and service life of the bearing. Toughness refers to the ability of a material to absorb energy without brittle fracture when subjected to impact or sudden loading. Through toughness testing, the impact resistance of the bearing material under complex working conditions can be evaluated, reducing the risk of bearing failure due to sudden impact. Simulating the cyclic loading conditions of the bearing in actual work, the fatigue performance of the bearing after long-term use can be evaluated. Fatigue life testing is important for predicting the service life of the bearing, optimizing design and material selection. New energy vehicles may be exposed to humid, salt spray and other corrosive environments, so corrosion resistance testing of the bearing material is necessary. By simulating the corrosion process under these environmental conditions, the corrosion resistance of the material can be evaluated to ensure the reliability of the bearing in harsh environments. New energy vehicles may generate high temperatures during operation, so the thermal stability of the bearing material needs to be tested. This includes evaluating the dimensional stability, strength changes and thermal expansion coefficient of the material at high temperatures to ensure that the bearing can maintain stable performance under high temperature conditions. In summary, the bearing material performance tester for new energy vehicle bearing machining plays an important role in ensuring the quality of bearings and improving the safety and reliability of new energy vehicles. The problem with the above technology is that during the performance testing of the bearing using the bearing material performance tester, the bearing needs to be assisted and limited by the placement block. However, when testing bearings of different sizes, the corresponding placement block needs to be replaced to drag and drop the bearing. Since the placement block and the bearing material performance tester are usually connected and fixed by multiple connectors and fixings, it takes a long time and effort for the user to disassemble and assemble the multiple connectors and fixings when replacing the placement block, thereby reducing the assembly convenience of the placement block.
