Abstract

The invention discloses a movement position detection mechanism, which comprises a fixed frame, which is used to be fixed on one of the moving parts and the running track; the roller shaft is rotatably fixed on the fixed frame; and the roller is fixed on the roller shaft. On, the surface of the roller is used to be in contact with the surface of the other of the moving part and the running track, and when the moving part moves, friction is generated between the roller and the contact surface of the other of the moving part and the running track Force, the roller rolls under the action of friction force, and drives the roller shaft to rotate; the position sensor, connected with the roller shaft, rotates under the driving of the roller shaft, and outputs the position signal of the moving part. The invention also discloses an X-ray imaging device. The invention uses the rolling friction force of the moving parts to rotate a roller fixed on the position detection mechanism, and converts the rotation of the roller to the position sensor, thereby realizing the position detection of the moving parts.

Description

technical field

[0001] The invention relates to a movement position detection mechanism and an X-ray imaging device adopting the movement position detection mechanism. Background technique

[0002] On some devices, some parts need to be moved manually, and the moving position of the moving part needs to be known, so the moving position of the moving part needs to be detected. Most of the position detection methods of moving parts currently used in some non-precision positioning equipment are to transmit the movement stroke of the moving parts to the movement position detection mechanism through some meshing transmission mechanisms, and finally to the position sensor. When this method of detecting the moving position of the moving part is adopted, there is a motion transmission between the moving position detection mechanism and the walking track of the moving part, which requires the existence of a transmission mechanism, that is, the contact surface of the two needs to be d...
