Wrong Position Detection of Angle Rolled Shaft in Roller Process
Abstract
In the roller process of shafts, it is essential to detect possible wrong positions in order to ensure stationary operation and production safety. This paper summarizes the detection, analysis and control methods of shaft wrong position in actual application and calibration process, in order to provide useful reference for the operation, management and maintenance personnel of the shaft.
1 Introduction
Roller process of shaft is one of necessary machining processes of shaft in cold production. During the production processing, due to the improper operation, resulting in the wrong position of the shaft, it will not only affect the deflection of the shaft, but also increase the processing time and reduce the production efficiency. Therefore, the wrong position of the shaft during the roller process needs to be detected, analyzed, controlled and corrected in time, so as to ensure the stable operation of the production line.
2 Detection and analysis of wrong position in shaft roller process
During the roller process of shaft, the changing of wrong position includes the wrong angle and the wrong size of the shaft. These two conditions will cause certain dynamic errors to the production process.
2.1 Wrong angle detection
Wrong angle position in the process is mainly caused by the wrong process design. For example, the production process design does not meet the accuracy requirements, or the machining process parameters setting is wrong. The wrong angle can generally be detected with a caliper, measuring pins or a protractor. If the parameters are wrong, the parameters can be modified or the process needs to be corrected.
2.2 Detection and control of shaft size wrong position
Shaft size wrong position mainly includes shoulder and concave shoulder of shaft. When the wrong position of shoulder and concave shoulder appears, it is necessary to measure and analyze and make the necessary corrections.
2.2.1 Measurement and analysis of wrong position
The wrong size of the shaft can be detected and measured with a caliper, ruler or vernier caliper. After measuring, compare the size and actual design value of the shaft, to determine the errors and make correction judgments.
2.2.2 Correction of wrong position
In the correction process, the wrong size of the shaft can be corrected directly by numerical control machine tool, or use the correct tool to correct the wrong position. For the production of large series shaft, it is more suitable to correct the wrong position with numerical control machine, increase the work efficiency and improve the accuracy of production.
3 Summary
The wrong position of shaft roller process must be detected, analysed and corrected in time, in order to prevent the static error of production line and to ensure the normal operation of the production line. This paper summarizes the detection, analysis and control methods of shaft wrong positions in actual application and calibration process, which provides useful reference for the operation, management and maintenance personnel of the shaft.
