Description
Technical field
This utility model relates to screw rod drive mechanism technical field, particularly to a kind of screw rod actuating device.
Background technology
Screw rod actuating device is widely used in a lot of machinerys, existing screw rod actuating device primary structure is that spiral has nut on screw rod, drives nut to move back and forth thereon by the rotation of screw rod or drives screw rod reciprocating rotating by moving back and forth nut.But, the problem that this device also exists lack of lubrication.Due to nut and screw rod to screw togather gap less, the lubricating oil of its internal reservoir is not enough, when screw rod is with nut high speed motion, the situation of both lack of lubrication can occur, make to wear and tear between nut and screw rod, not only affect it and normally use, and shorten its service life.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of profit and changes effective, does not haves the screw rod actuating device of lack of lubrication situation when nut and screw rod high speed motion.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of screw rod actuating device, including screw rod and nut, described nut is axially provided with helical tooth, described helical tooth coordinates with the helicla flute of described screw rod, described screw rod two ends are arranged on fixed mount by bearing, described nut is fixed on connecting plate, pilot hole is had on described connecting plate, described pilot hole is interspersed with guide post, described guide post and described screw rod be arranged in parallel, and wherein one end of described screw rod is additionally provided with driving member.
Further, described nut is set to two, the respectively first nut and the second nut.
Further, the first described nut and the second nut are arranged on screw rod.
Further, the helical tooth on the first described nut and the second nut is uniformly arranged four.
Further, the described pilot hole in connector is arranged on its one end, and the other end is provided with two jig arm worked in coordination, and described nut is arranged between two jig arm.
Further, cooperate two described jig arm having through hole, the nut between said two jig arm is fixed by the fixing bolt through the through hole of two jig arm.
Further, described driving member is gear or sprocket wheel or belt wheel one therein.
What employing technique scheme this utility model obtained has the beneficial effect that described nut coordinates to come work by the helical tooth arranged with the helicla flute of screw rod, helical tooth is had in only having part due to the helicla flute of screw rod Yu nut screw connection position, remainder is used for storing lubricating oil, make lubricating oil can arrive whole positions of nut and screw rod contact surface, make its lubricant effect preferable, and two nuts are simultaneously located at together so that bigger active force can be born between nut and screw rod.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is A-A sectional structure schematic diagram of the present utility model；
In figure: 1. guide post, 2. connector, 2-1. pilot hole, 2-2. jig arm, 3. fixed mount, 4. bearing, 5. screw rod, 6. the first nut, 7. the second nut, 8. driving member, 9. oil groove, 10. fix bolt.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.At this it should be noted that be adapted to assist in for the explanation of these embodiments and understand this utility model, but it is not intended that restriction of the present utility model.As long as just can be mutually combined additionally, technical characteristic involved in each embodiment of this utility model disclosed below does not constitutes conflict each other.
In conjunction with attached Fig. 1 and 2, this utility model is further described, make enforcement this utility model that those skilled in the art are convenient.This utility model screw rod 5 actuating device, including guide post 1, connector 2, fixed mount 3, screw rod 5, nut；Described nut is screwed on described screw rod 5, described nut is preferable to provide two, it is respectively the first nut 6 and the second nut 7, the first described nut 6 and the second nut 7 are arranged on screw rod 5, spacing between described first nut 6 and the second nut 7 is reconciled according to requirements, and its spacing scope can also be determined according to the length of screw rod 5；Described nut is axially provided with helical tooth 9, and described helical tooth 9 coordinates with the helicla flute of described screw rod 5, and described helical tooth 9 offers four, arranges uniformly on the first nut 6 and the second nut 7；Described screw rod 5 two ends are arranged on described fixed mount 3 by bearing 4, described nut is fixed on described connecting plate, pilot hole 2-1 is had on described connecting plate, described guide post 1 passes from described pilot hole 2-1, described guide post 1 and described screw rod 5 be arranged in parallel, wherein one end of described screw rod 5 is additionally provided with driving member 8, and described driving member 8 can be arranged on the inner side of bearing 4 can also be arranged on the outside of bearing 4.
This utility model arranges two nuts, and screw rod 5 rotates forward when, the helical tooth 9 of one of them nut contacts with the helicla flute of screw rod 5；When screw rod 5 inverts when, the helical tooth 9 of another nut contacts with the helicla flute of screw rod 5.When connector 2 drives and moves back and forth about nut, be similarly a nut and contact with the helicla flute of screw rod 5, so interval contact work with screw rod 5, substantially increase the working time of nut, add service life.
Pilot hole 2-1 in connector 2 described in the utility model is arranged on its one end, and the other end is provided with two jig arm 2-2 worked in coordination, and described nut is arranged between two jig arm 2-2；Having through hole in cooperate two described jig arm 2-2, the described through hole in two jig arm 2-2 is passed by fixing bolt 10, is fixed on by nut between two jig arm 2-2.
Driving member 8 described in the utility model is gear or sprocket wheel or belt wheel one therein, it is also possible to for other driving members 8 beyond these three, show not to this further restriction.
This utility model to described nut to coordinate to come work by the helical tooth 9 arranged with the helicla flute of screw rod 5, helical tooth 9 is had in only having part due to the helicla flute of screw rod 5 with nut screw connection position, remainder is used for storing lubricating oil, 9 make lubricating oil can arrive whole positions of nut and screw rod 5 contact surface, make its lubricant effect preferable, and two nuts are simultaneously located at together so that bigger active force can be born between nut and screw rod 5.External power supply band follower link 2 reciprocating motion, thus drive screw rod 5 high speed positive and negative rotation, external power supply can also drive screw rod 5 positive and negative rotation, thus band follower link 2 moves back and forth at a high speed.
Above in association with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model is not limited to described embodiment.For a person skilled in the art, in the case of without departing from this utility model principle and spirit, these embodiments are carried out multiple change, revises, replace and modification, still fall within protection domain of the present utility model.
