On the one hand bar rotates, on the other hand move in a straight line, and finely tunes the essence that the rotary motion of screw rod can be finely tuned to needs at this time
Close parts apply the torsion of rotation, and frictionally damage is caused to precision parts.
Invention content
Its purpose of the invention, which is that, provides a kind of dead-beat fine motion adjustment mechanism, solves existing adjustment mechanism presence pair
Precision parts easily cause the problem of frictionally damage.
It adopts the technical scheme that achieve the above object, a kind of dead-beat fine motion adjustment mechanism, including is equipped with strip
The upper end of the fine tuning fixed plate in shape hole, the fine tuning fixed plate is horizontally fixed with fine-tuning stent, fine-tuning stent inner sleeve through round nut
Equipped with fine tuning screw rod, fine tuning screw rod between 1# holding screws and fine-tuning stent through being fixed, one end end of the fine tuning screw rod
It is fixed with dome-type nylon screw on face, finely tunes the other end of screw rod through being threaded with fine-tuning nut, one end of fine-tuning nut
It is placed in fine-tuning stent, fine-tuning nut between 2# holding screws and fine-tuning stent through being fixed, in the fine tuning fixed plate
High-head knurling screw is additionally provided in elongate holes.
Advantageous effect
The present invention has the following advantages compared with prior art.
It is an advantage of the invention that component part is few, simple in structure, by the cooperation between parts, precision is high, and operation is flat
Surely, manufacturing cost is low, easy to operate, and friction will not be caused to damage to the torsion for needing the precision parts finely tuned to apply rotation
Wound.
Description of the drawings
Below in conjunction with attached drawing, the invention will be further described.
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
A kind of dead-beat fine motion adjustment mechanism includes the fine tuning fixed plate 2 equipped with elongate holes, as shown in Figure 1, described micro-
It adjusts the upper end of fixed plate 2 to be horizontally fixed with fine-tuning stent 6 through round nut 4, fine tuning screw rod 7 is arranged in fine-tuning stent 6, finely tunes spiral shell
Bar 7 is fixed with dome-type through being fixed between 1# holding screws 5 and fine-tuning stent 6 on one end end face of the fine tuning screw rod 7
The other end of nylon screw 3, fine tuning screw rod 7 is placed in fine-tuning stent 6 through being threaded with fine-tuning nut 9, one end of fine-tuning nut 9
Interior, fine-tuning nut 9 between 2# holding screws 8 and fine-tuning stent 6 through being fixed, the elongate holes in the fine tuning fixed plate 2
Inside it is additionally provided with high-head knurling screw 1.
The fine tuning screw rod 7 is equipped with kidney slot, and 1# holding screws 5 are fixed in kidney slot.
The fine-tuning nut 9 is equipped with annular groove, and 2# holding screws 8 are fixed in annular groove.
It is connected through a screw thread between the fine tuning screw rod 7 and fine-tuning nut 9, is screw thread pair, rotary fine adjustment nut 9, fine tuning
Screw rod 7 will not be rotated along straight ahead or retrogressing, fine tuning screw rod 7, realize dead-beat fine motion adjustment.
In the present invention, the 1# holding screws 5 are embedded in the kidney slot of fine tuning screw rod 7, and finely tuning screw rod 7 in this way can only edge
Straight ahead or retrogressing cannot rotate, and thus will not cause to rub to the torsion for needing the precision parts finely tuned to apply rotation
It wears wound；The 2# holding screws 8 are embedded in the annular groove of fine-tuning nut 9, and such fine-tuning nut 9 is axial to be fixed,
It can only be rotated around fine-tuning stent 6；It is optical axis and fine-tuning stent 6 that the fine tuning screw rod 7, which only has latter half to have screw thread, first half,
Hole cooperation, primarily serve guiding role, not only make its stable movement, but also precision is high；The high-head knurling screw 1 is placed in
In the elongate holes for finely tuning fixed plate 2, it is easily installed entire dead-beat fine motion adjustment mechanism, is convenient for up and down adjustment；The hemisphere
Shape nylon screw 3 is fixed on fine tuning screw rod 7, the relatively soft precision parts for needing to finely tune convenient for protection of nylon.Finely tune screw rod 7
Be connected through a screw thread between fine-tuning nut 9, be screw thread pair, rotary fine adjustment nut 9, fine tuning screw rod 7 just along straight ahead or
It retreating, fine tuning screw rod 7 will not rotate, and realize that dead-beat fine motion adjustment, this dead-beat fine motion adjustment mechanism are not only simple in structure,
By the cooperation between parts, precision is high, operates steadily, and will not apply rotation to the precision parts for needing to finely tune
Torsion causes frictionally damage.
The structure feature of the present invention is 1）1# holding screws are embedded in the kidney slot of fine tuning screw rod, such rotary fine adjustment nut,
Fine tuning screw rod can only cannot be rotated along straight ahead or retrogressing, thus will not apply rotation to the precision parts for needing to finely tune
The torsion turned causes frictionally damage；2) 2# holding screws are embedded in the annular groove of fine-tuning nut, such fine-tuning nut it is axial into
It has gone fixation, can only have been rotated around fine-tuning stent；3) it is optical axis and fine tuning that fine tuning screw rod, which only has latter half to have screw thread, first half,
The hole of holder coordinates, and primarily serves guiding role, not only makes its stable movement, but also precision is high；4) high-head knurling screw is placed
In the strip hole of fine tuning fixed plate, it is easily installed entire dead-beat fine motion adjustment mechanism, is convenient for up and down adjustment；5) entire straight
The dynamic adjustment mechanism that declines contains only 9 parts, and simple in structure, manufacturing cost is low, easy to operate.
