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 every other embodiment obtained, shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of feed screw nut anti-rotation structure, including lead screw
1, lead screw 1 is fixedly connected with one end of Anti-rotary block 2, and the other end of Anti-rotary block 2 is fixedly connected with the tail end of screw rod 3, and on Anti-rotary block 2
It is cased with anti-rotation lantern ring 4, Anti-rotary block 2 is terrace with edge structure, and terrace with edge is fixedly connected compared with butt end with lead screw 1, and terrace with edge thinner end and screw rod 3
Tail end be integrally formed, through being equipped with anti-rotating hole 9, the shape of anti-rotating hole 9 and the cross-sectional shape phase of terrace with edge on anti-rotation lantern ring 4
Together, anti-rotating hole 9 is less than size of the terrace with edge compared with butt end cross section, and anti-rotating hole 9 is more than the size of terrace with edge thinner end cross section, anti-rotation
Lantern ring 4 is sleeved on the head of Anti-rotary block 2, due to Anti-rotary block 2 be terrace with edge structure, therefore anti-rotation lantern ring 4 moved to Anti-rotary block 2 it is deeper,
That then blocks between anti-rotation lantern ring 4 and Anti-rotary block 2 is closer.
It is threaded with nut 5 on screw rod 3, runs through on nut 5 and is equipped with mounting hole 6, bolt 7, anti-rotation are inserted in mounting hole 6
The outer surface insertion of lantern ring 4 is equipped with internal thread threaded hole 8, and bolt 7 is threadedly coupled with internal thread threaded hole 8, and the diameter of mounting hole 6 is less than
The diameter on 7 head of bolt, bolt 7 are rotatably inserted in mounting hole 6, and the quantity of mounting hole 6 is 2-4 groups, internal thread threaded hole 8 with it is solid
The quantity for determining hole 6 is equal and position is corresponding, and the diameter of anti-rotation lantern ring 4 is more than the diameter of nut 5, and the thickness of the nut 5 is more than
The thickness of anti-rotation lantern ring 4, and there are gap, the length sides of the length direction and lead screw 1 of bolt 7 between nut 5 and anti-rotation lantern ring 4
To being consistent, anti-rotation lantern ring 4 is sleeved on after the head of Anti-rotary block 2, nut 5 is threadedly coupled with screw rod 3, when 5 turns of nut
When moving 3 bottom of screw rod, mounting hole 6 is opposite with the position of internal thread threaded hole 8, is inserted into bolt 7 at this time, and by the bottom of bolt 7
