Motor drives forward or reverse, opened up on the minute hand plate it is long to the axial consistent slotted hole of the teeth-free guide rod, it is described
Teeth-free guide rod has and sample loading gun needle unit frame anodontia nut equal in number, the inside fixed one of each anodontia nut
A connecting rod, each connecting rod pass through an affixed sample loading gun needle unit frame after the slotted hole.
Further, fixed vertical plate is distinguished at the both ends of the minute hand plate another side, and the optical axis is hubbed on institute by bearing
It states on vertical plate, one end of the optical axis passes through fixed synchronous pulley A after the vertical plate, with the same side the synchronous pulley A
The fixed stepper motor in the inside of the vertical plate, the motor shaft of the stepper motor is fixed one after the vertical plate of the side
Winding synchronous belt on synchronous pulley B, the synchronous pulley A and synchronous pulley B.
Further, the screw pitch of the anodontia nut is different.
Teeth-free guide rod is also no spiral shell guide rod, anodontia screw rod, and anodontia polished rod matches, teeth-free guide rod with anodontia nut
Rotation input, frictional drive drive anodontia nut move along a straight line and be accurately positioned on teeth-free guide rod.Compared with lead screw, tool
Have: 1. without clearance, low noise；2. high transmission efficiency, low running loss；3. safety, nut can skid automatically when excess load does not damage
And other elements；4. high-seal, dust-proof feature.
Compared with prior art, the utility model has the following characteristics:
1. minute hand transmission is carried out using teeth-free guide rod/anodontia nut structure, compared to the transmission side of conventional cam structure
Formula has the characteristics of high transmission accuracy, speed is fast, low noise.It is possible to prevente effectively from backhaul gap
2. on the one hand reducing movement mechanism transverse width using teeth-free guide rod/anodontia nut structure, increase loading device
It is loaded flexibility, reduces equipment volume, still further aspect can increase the transmission accuracy of movement mechanism, reduce failure rate.
