Description

Technical Field

[0001] The invention relates to a method for quickly detecting the flatness of a part of a local arc installation surface, and belongs to the technical field of mechanical engineering quality control. Background Art

[0002] In the field of mechanical engineering, especially in industrial production and quality control, the flatness of the arc mounting surface is one of the most important indicators, which directly affects the operating efficiency and service life of the equipment.

[0003] Unlike the measurement of flatness of a plane, the measurement of the flatness of an arc surface is more complicated. High-precision measuring instruments such as laser interferometers and three-coordinate measuring machines are commonly used for flatness measurement. Although they can obtain very accurate results, there are many problems for measurement scenarios that do not require high precision: (1) Small and medium-sized enterprises or small production lines cannot afford the high cost of high-precision measuring instruments. (2) High-precision measuring instruments require professional personnel to operate, and the measurement process takes a lot of time and effort, which seriously reduces the progress of the production line. (3) High-precision measuring instruments have strict requirements for use conditions and are prone to failure in ordinary production environments. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a method for quickly detecting the flatness of parts such as local arc mounting surfaces, thereby solving the above-mentioned technical problems.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: a method for quickly detecting the flatness of parts of local arc mounting surfaces, characterized in that it includes the following steps: Step 1: Press diagonally, select two diagonal points of the arc installation surface, and apply a certain amount of pressing force respectively; Step 2: Use a dial indicator to measure the size changes in the diameter and circumferential directions of the arc mounting surface. Step 3: Data analysis: by analyzing the data of diagonal pressing and dial indicator measurement, determine whether the flatness of the arc installation surface meets the basic requirements; Step 4: Optimization and adjustment: According to the results of data analysis, the arc installation surface can be optimized and adjusted to achieve the required flatness; Step 5: Repeat the measurement. After completing the adjustment, repeat the diagonal pressing and dial indicator measurement of the arc installation surface to verify the adjustment effect and ensure that the flatness of the arc installation surface meets the requirements.

[0006] Furthermore, in step one, the magnitude of the pressing force can be determined according to actual conditions, and a pressing device can be used to apply a constant pressure with a pressure value of 400g-600g. A feeler gauge can also be used to assist in determining the relative height difference of the pressing point.

[0007] Furthermore, in step 2, the model of the dial indicator can be selected to have an accuracy of 0.01 mm. During measurement, multiple measurements are required to ensure the accuracy of the data. The measurement is performed three times, and the average value is taken as the final measurement result.

[0008] Furthermore, in step three, by setting a threshold, when the measured data exceeds the threshold, it can be judged that the arc installation surface is uneven and needs to be adjusted; specifically, the maximum allowable deviation in the diameter direction and the circumferential direction is set to 0.5mm. If the measured data exceeds this range, the arc installation surface is judged to be uneven.

[0009] Furthermore, in step 4, optimization and adjustment are performed by adjusting the tightness of the mounting bolts and correcting the shape of the mounting template.

[0010] The beneficial effects of the present invention are as follows: the method for quickly evaluating the flatness of an arc surface is simple and easy to implement, and can replace high-precision measuring instruments in small and medium-sized enterprises or small production lines, thereby greatly reducing the measurement cost.

[0011] Easy to operate: The operation steps of the method of the present invention are easy to master and can be performed by ordinary workers after simple training, thereby reducing the labor cost of the enterprise.

[0012] Strong practicability: The present invention is aimed at flatness measurement scenarios that do not require high precision, and can fully meet the needs of flatness measurement scenarios that do not require high precision, and is more practical.

[0013] Fast measurement speed: The measurement process of the present invention is fast, and whether the flatness of the installation surface of the product meets the requirements can be directly measured at the production site, which is suitable for fast production turnover and improves production efficiency.

[0014] In summary, compared with the prior art, the present invention has the advantages of low cost, simple operation, wide application range, fast measurement speed, moderate accuracy, and avoidance of excessive measurement. It is a fast, low-cost and efficient method for evaluating the flatness of arc mounting surfaces, and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
