Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The all other embodiment obtained, shall fall within the protection scope of the present invention.
It please refers to Fig.1 and Fig. 2, the utility model embodiment provides a kind of displacement detector of band bias adjustment function,
Including connecting shaft 1, gear 2, rack 3, encoder 4 and apart from adjustment component, wherein gear 2 fixation install in connecting shaft 1
One end, encoder 4 install the number of turns and angle for recording rotation in the other end of the connecting shaft 1, utilize rotary motion and straight line
The conversion relation of movement obtains displacement and position, and distance adjustment component is between the gear 2 and the encoder 4.In reality
In the work of border, before measurements, distance adjustment component adjustment the distance between 2 center of gear and rack 3 are first passed through so that tooth
Wheel 2 and rack 3 can engage well, then measure again, gear 2 rotates on rack 3, and encoder 4 will be correspondingly
It is recorded, to complete displacement detecting.Distance adjustment component is used, range deviation mistake between gear 2 and rack 3 is avoided
The problem of influencing measurement accuracy greatly.
