In the field of precision measurement and efficient testing, the rotary probe has become an indispensable tool in industrial production and quality inspection due to its unique design and working principle. This paper will analyze the structure, working principle, application field and advantages of the rotating probe in detail.
The rotating probe is mainly composed of rotating shaft, probe, circuit board and motor. Its working principle is that the rotating shaft is driven by the motor to rotate, so that the probe can rotate on the surface of the sample to be tested. In the process of rotation, the probe is in contact with the surface of the tested sample by means of its own weight and the force spring, so as to make accurate measurement.
Specifically, when the motor is started, the rotating shaft starts to rotate, which drives the probe to rotate on the surface of the sample to be tested. At this time, the probe maintains a certain contact force with the surface of the tested sample under the action of the force spring. When the probe moves on the surface of the sample to be tested, the sensor will sense the position change of the contact surface of the probe in real time and convert it into an electrical signal. After the circuit board receives the electrical signal, it will be processed and converted into a digital signal, and finally displayed through the display to obtain the corresponding test data.
Rotary probes are widely used in wire harness, switch testing, terminal testing, high current testing and other fields. Threaded rotating test probes are particularly common in automotive harness testing. Since the terminal of the automobile wiring harness usually has an internal thread structure, the thread on the probe can be matched with the needle sleeve of the internal thread to prevent the probe from shifting, thereby ensuring the accuracy and stability of the test.
The rotating probe can also be used to measure surface topography, roughness, hardness and other parameters. In industrial production, these parameters are of great significance for product quality control. Through the precise measurement of the rotating probe, enterprises can find problems in the production process in time and take effective measures to improve.
Advantages of rotating probes
High accuracy: The rotating probe adopts the measurement method of mechanical contact, which has high accuracy. At the same time, its unique rotating design can ensure that the probe is fully in contact with the surface of the sample to be tested, further improving the measurement accuracy.
Efficient and convenient: The operation of the rotating probe is simple and convenient, and the measurement task can be completed quickly. At the same time, the degree of automation is high, which can greatly reduce the difficulty and cost of manual operation.
Strong durability: The rotating probe is made of high-quality materials and has high durability. Under normal use, its service life is long and can meet the needs of long-term use.
In summary, with its unique structure and working principle, the rotating probe shows its performance and wide application prospect in the field of precision measurement and efficient testing.
