A method for automatic detection of shafts

Abstract

The invention discloses an automatic shaft type detection method. The method comprises the following steps of: S1, assembling shaft parts into a guide assembly for positioning; and S2, detecting the shaft part assembled in the guide assembly by using a detection assembly. The detection assembly comprises a sliding table and detection needles. The detection needles are driven by the sliding table to move. Whether the shaft parts are in place or not is accurately detected by means of the detection needles touching the shaft parts in the guide assembly. According to the automatic shaft type detection method, the detection needles are driven by the sliding table to detect the shaft parts in the guide assembly; whether the shaft parts are in place or not, and whether missing shaft or shaft deformation exists or not are detected by the means of the detection needles touching the shaft parts; the mechanism is reliable in detection mode, and light and compact in structure; and whether a shaft,shaft deformation or the like exists in each detection through hole can be accurately detected in a narrow space.

Description

technical field [0001] The invention relates to an automatic shaft detection method, which belongs to the technical field of shaft detection. Background technique [0002] For some small motors such as small stepping motors, synchronous motors, etc., in the production and assembly process, there has always been a problem that the position of the small motor shaft cannot be detected before assembly. When the number of motor shafts that need to be assembled at the same time is large, the spatial position distribution is mixed, and the distance between the shafts is small, the photoelectric sensor detection device is usually used to directly detect the placement position of a single shaft, but this detection method The detected motor shaft interferes with other motor shafts to be detected in space, which is not conducive to the position detection. In addition, ordinary mechanical mechanisms are often used for position detection, but the mechanical mechanism is limited to a sma...

Problems solved by technology

[0002] For some small motors such as small stepping motors, synchronous motors, etc., in the production and assembly process, there has always been the problem that the position of the small motor shaft cannot be detected before assembly

When the number of motor shafts that need to be assembled at the same time is large, the spatial position distribution is mixed, and the distance between the shafts is small, the photoelectric sensor detection device is usually used to directly detect the placement position of a single shaft, but this detection method The detected motor shaft interferes with other motor shafts to be detected in space, which is not conducive to the position detection

In addition, ordinary mechanical mechanisms are often used for position detection, but the mechanical mechanism is limited to a small space, and it is impossible to detect whether all the identification axes have reached the specified position
