An automatic press-fitting machine for a retaining ring for a shaft and a work detection method

Abstract

The invention relates to an automatic pressing fit machine for a shaft check ring and a work detection method, and belongs to the technical field of automatic assembly and detection of shaft check rings. A part to be assembled is arranged in a positioning seat of pressing fit equipment, and an electric cylinder drives a pressing fit head to press the shaft check ring into a positioning groove. In the pressing fit process, a displacement sensor and a pressure sensor carry out digital / analog conversion on collected displacement data and pressure data and then upload the converted displacement data and pressure data to an industrial control computer. A pressure-displacement curve is obtained by using common Excel, Minitab and other software programs, and the correspondence relationship between pressure and displacement and the assessment criterion are displayed in real time through a display screen. The automatic pressing fit machine for the shaft check ring and the work detection method are not affected by human factors in the pressing fit process, and whether the pressing fit curve is qualified can be judged rapidly by monitoring the pressure-displacement curve used in the pressing fit process. The problems that according to an existing manual assembly method, the labor intensity of an operator is large, it can not be effectively guaranteed that the shaft check ring is completely assembled in a workpiece clamping spring groove, and a visual inspection method is low in accuracy are solved.

Description

technical field [0001] The invention relates to an automatic press-fitting machine for a shaft retaining ring and a working detection method, and belongs to the technical field of automatic assembly and detection of a shaft retaining ring. Background technique [0002] The existing shaft retaining ring assembly method is generally manual assembly by using a circlip pliers. After the assembly is completed, a visual inspection is carried out to confirm whether the shaft retaining ring is properly assembled. The disadvantage of this assembly method is that manual assembly cannot effectively ensure that the shaft retaining ring is completely assembled into the spring groove of the workpiece, and there is a risk of failure of the shaft retaining ring; the second is that the assembly process is manual operation, and the labor intensity of the operator is high. ; Third, the accuracy of the visual inspection method is not high. SUMMARY OF THE INVENTION [0003] The purpose of the...

Problems solved by technology

[0003] The object of the present invention is to, aiming at the deficiencies of the above-mentioned prior art, provide an automatic press-fitting machine and a work detection method for a shaft retaining ring, which ensures that the shaft retaining ring is 100% assembled in place during the press-fitting process, and the process of press-fitting Use the pressure-displacement curve to monitor, and judge whether the press-fitting process is qualified according to the testing standards; solve the problem that the existing manual assembly cannot effectively ensure that the retaining ring for the shaft is completely assembled into the circlip groove of the workpiece, and the labor intensity of the operator is high.
